Description

Ski boot and snowboarder pull-out aid

The invention relates to an extension aid for taking off a snowboarder or ski boot comprising a manually operated lever arm, a lower attack element or a plurality of lower engagement elements, which are fixedly connected to the lever arm in a lower region of the lever arm and which can be attached to the shoe outer side, and a upper handle element which is connected to the lever arm in an upper area. The invention also relates to a manually operated rod part, which can embrace the upper edge of a ski boot on the rear side, so that the shoe can be stripped down, and a ski pole as a pull-out.

Furthermore, the invention relates to a method for taking off a snowboard or ski boot under the manual use of the extension aid according to the invention and the use of the pull-out invention for winter sports shoes, mountain boots, riding boots, rain boots, rubber boots, climbing shoes, inline skating shoes, ice hockey shoes, skating shoes, cross country boots or other difficult to extend Shoes.

Alpine boots, especially winter sports boots such as ski boots or snowboard school, must fit tightly on the foot. Therefore, hikers or athletes regularly have difficulty getting out of this school. Wet or frozen shoes are difficult to hold with your hands while the foot is pulled up with the thigh muscles to pull off the footwear. The back is regularly bent and bent forward to hold the boot with your hands on the back of the shoe while the foot is cumbersome drawn to the body. A cramping of exhausted muscles or tendon tears can not be ruled out in this strenuous and body-bending movement.

To remedy these problems hitherto cumbersome shoe constructions with built-in exit shaft, e.g. in EP 1 496 766 B1.

In general, pull-out aids to facilitate the removal of shoes, boots or the like footwear from the prior art are removable and known for example commonly known as "boot jackets." This usually consists of a wooden board, the one end has a U-shaped recess into which the footwear can be inserted and tilted, so that the person from a sitting position can remove the footwear to be pulled out by pulling up the foot.

The application of such an boot jack is shown in the patent document US 6,135,331. This ski boot remover includes a bottom surface and a contact lip stepped therefrom, which can engage with the rear binding extension of the ski boot. To use this ski boot remover, the person holds the bottom plate with one foot on the ground while using the other foot to maneuver the shooting boot into the contact angle and forcefully pull the foot up to slip out of the locked shooting boot. Then, the second shoe is pulled out, the now shoe-free foot must press the bottom plate down to fix it.

This Stiefelknechtanordnung has significant disadvantages. First, it needs a given rear side profile on the ski boot that fits exactly into the contact lip of the boot jack. In addition, the extraction of the boots with the bottom plate is very cumbersome, because always at least one foot must be used to fix the bottom plate, which is particularly unpleasant with the already extended foot on a wet floor slab. In addition, the boot can not be pulled out well when awkward with the other foot on the bottom plate must be pressed down.

In particular, using the boot jack, the anterior tibial muscles and posterior calf muscles are fully stressed when the shoe is removed, because the person must bring the foot to be pulled out into a raised position and hold it to pull it out of the shoe. The actual pulling force comes from the thigh muscles, especially in a sitting position, the thigh muscles have to apply the tensile force at an unfavorable angle, because the knee joint is strong, while the shoe flies itself in an unfavorable horizontal position on the bottom plate. In the state of boot jack is indeed often better to use, but this exhausted skiers can no longer sit down to take off the debtor. A help of other muscle groups such as the arms is not possible with this device. Just tight fitting tight shoes are to take off with this arrangement, only with great effort, because many people or children can not muster enough force in the anterior tibial muscle and posterior car muscles to set the foot sufficiently and in this upright position with the thigh muscles alone from the shoe to draw. In addition, the bottom plate must be bulky and quite heavy, in order to ensure the necessary contact surface for the second foot and to survive the force fracture resistant.

An improved construction provides the collapsible device for taking off ski boots, which is described in the utility model DE 20 2007 001 555 U l. Here, the base plate on an additional hinged shoe pad, which is provided with a holding claw, in which the shoe heel can be supported. By subsequently moving the shin in the vertical position, the foot pulls out of the ski boot. This device improves the extraction process by the better angle but otherwise is more complicated because the bottom plate can not be locked with the second foot and thus must be particularly heavy and cumbersome to prevent slippage of the plate when pulling out.

A further improvement is provided in the patent GB 2 445 404 A. Also described herein is a floor panel having two protruding hooks into which a rear ski boot extension can be inserted. It is possible to use this plate both while sitting and standing. The bottom plate can be brought with an executed support in an inclined position. This arrangement improves the angle when removing the shoe, makes the device but cumbersome in the state, because the base plate must be held with a second foot, a hand or the ski poles, so that they do not slip when pulling out. The ski boot can be pulled out by pressing the knee forward and putting on the foot. However, all forces must be developed from the leg muscles. In addition, the plate is quite heavy and bulky.

In the document US 4,666,070 another ski boot extractor is described which has a base plate and a hook for the rear boot binding extension. Here is the problem of locking the bottom plate thereby solved that the bottom plate is pressed with a fixable handle bar down. Thus, the ski boot can also be clamped to the front attachment process. This device has some disadvantages. First, a lightweight floor panel construction is pulled up by raising the foot at the rear. In addition, the user must pry the knee between the handle bar mounts to slip out of the shoe. Furthermore, the construction is very cumbersome and not suitable for mobile use. Different shoe designs do not fit into the given bottom plate dimensions or hooks, so this device is not universally applicable.

A classic Stiefelknecht is deposited in the utility model DE 295 12 289 U l. This pull-out aid has two handles with which the person can push the boot jack down to the ground. By putting on the clad foot, the shoe can engage in a jagged restraint at the top or heel of the shoe and thus be pulled off when the foot is raised further. Here, the power to take off the shoe is based exclusively on the leg muscles. There are also no leverage used. In addition, the wire construction is bulky in construction and the serrated retention device can damage the outer shoe wall.

The solutions described in the prior art therefore all have serious disadvantages.

It is therefore an object of this invention to provide a pull-out that significantly simplifies the extraction process of heavy and bulky alpine or winter sports shoes and facilitates the necessary movement sequence. In addition, the pull-out in the production should be cheaper, less bulky, lighter in weight and also portable. Furthermore, the device should be used universally for different boot sizes variable and also for exhausted, weaker or younger people easier and without much effort in the sitting position or be operated from a standstill.

These objects are achieved with a pull-out according to the claims.

In particular, these objects are achieved by a pull-out to take off a Snowboarder or ski boot with:

a manually operated lever arm,

a lower engagement element or a plurality of lower engagement elements, which are firmly connected to the lever arm in a lower region of the lever arm and which can be attached to the outside of the shoe,

wherein at least one lower engaging element releasably fix the extension to the outer shoe, and

an upper handle member connected to the lever arm in an upper portion.

This solution offers several advantages. In particular, she uses a completely new principle to take off a tight-fitting shoe. While previous systems relied on the leg or foot muscles, it is now possible, with the aid of the extended hands and the arm power, to strip the shoe from the foot with a leverage effect.

Furthermore, the extension aid according to the invention utilizes the advantageous effects of leverage forces which are transmitted via the lever arm on the shoe back. As a result, the shoe is not pressed down and stripped off relative to the foot, but additionally levered down. In this case acts at the lower point of attack on the shoe on the extension a wegdrückende force that pushes the shoe forward and downward of the body of the person while the foot can be pulled out of the shoe without complaint up or to the body.

The lever arm potentiates the forces, so that only small arm forces are necessary to exert sufficient pressure on the back of the foot, so that it can be easily removed. The lever arm should preferably be at least 1 00 mm long, but may have up to 1 500 mm in length. Particularly preferred are lengths between 250 and 700 mm. For some applications, a length of 400 mm to 900 mm is suitable; Particularly preferred in this case is a length of 500 mm to 750 mm. The pull-out with the lever arm and the other elements, such as attack elements or engagement devices, etc. may also generally preferred have the above total lengths.

The total length of the extension aid is chosen differently depending on the application. Two variants are conceivable. Either the pull-out aid is used sitting or standing. In the seat variant, the pull-out aid is shorter so that a person can comfortably put on the pull-out aid on the ski boot and pry it down. The ski boot is then stripped off the foot. Suitable overall lengths are here from 200 to 600 mm.

In the stand variant, the lever is correspondingly longer. Here, the lever is pushed backwards and downwards, so that the foot can be easily pulled upwards out of the shoe. Preferred overall lengths are here from 400 to 1000 mm.

The person skilled in the art, using his specialist knowledge, can set the corresponding overall length of the pull-out aid so that persons of different sizes or children can operate the pull-off aid without inconvenient body contortions. In a particular embodiment of the invention, the length of the extension aid is variably adjustable. For this purpose, a plurality of hollow rods can be guided into each other and be locked, for example by a screw. In a particular embodiment, the rods can be fixed against each other after pulling to the desired length without screw by turning the rods. Typical mechanisms for this are already known from the prior art for ski poles.

In addition, the shoe is preferably offset in a rotation in the direction of the lever forces. By this additional levered rotary movement, the exit from the shoe is also relieved, because the foot does not have to be so strong to slip out through the shoe channel can. The forces act from the shoe to the foot and not vice versa.

None of the previous solutions in the prior art recognizes the inventive lever and / or rotational action mechanism of the current technical solution.

The pull-out aid can be used standing up or sitting down. Even in the preferred seat variant while the knee joint must not be fully angled. Instead, the leg can also be stretched forward when sitting in order to develop better bodywork forces as in the stand version. In the extraction movement, only a slight angle of the knee joint is sufficient. It is particularly advantageous that with the lever, the hands can be used to take off the shoe without the people laboriously bend their back to prevent themselves with the arms and hands to the shoe edge. The present pull-out aid therefore also acts as an extension arm.

These features of the present invention are particularly beneficial for exhausted winter sports enthusiasts or the elderly, because they do not have so flexible joints and the usual diffraction and stretching movements when pressing down heavy ski boots or snowboard boots can no longer run free of complaints. Also, no bottom plate needs to be fixed with the second foot. Thus, the person can support himself with the second foot and gains when pulling out a higher stability without having to keep in balance while both legs have to perform complex movements.

In addition, the present pull-out aid is universally applicable and does not have to be adapted to specific boot sizes. Depending on the boot height, the lower attack element is higher or lower on the back of the shoe. In this case, the attack element can be set at the very bottom of the shoe sole or heel paragraph or higher on the back of the shoe.

It is also an embodiment conceivable in which the lower engagement element rests as an extension of the lever arm only on the outer shoe. However, this can lead to the action of the leverage forces the merely applied attack element slipping past the left and right of the back of the shoe. To avoid this, the lower engagement element should be shaped in such a way that it can fix the outer shoe reversible and thus prevent the extension aid at the level of the attack site from the side breaking. In the following, various variants for the formation of the lower attack element are presented.

In a preferred embodiment, the lower engagement element is designed as a semicircular jaw rail, which can accommodate the outer shoe. In this case, the engagement element forms a rail which surround the outer shoe and can fix it laterally. Thus, a lateral slipping of the engaging element is prevented by the shoe at the lower point of attack The sphincter is thereby introduced into the mouth rail and thus fixed. A variant of this first embodiment is shown in FIG. The mouth width is preferably between 40 mm and 1 20 mm.

Preferably, the extension aid also includes a lower tab or tongue which is connected to the lever arm or the lower engagement element and which can be guided under the shoe.

Especially in an embodiment without engagement device, this tongue is advantageous in order to transfer the leverage forces on the heel of the heel and possibly also the shoe sole of the boot. The pivot point here is at the level of the fixing rail. In this embodiment, the downward pressing force and the leverage are in the foreground, while only a comparatively small torque is transmitted to the shoe.

Preferably, however, the pull-out aid according to the first embodiment also comprises an engagement device which is fixedly or movably connected between the upper grip element and a lower engagement element with the lever arm and which can be inserted into the inner boot.

Basically, it is in all variants of advantage if the extension aid is formed in one piece and preferably contains no moving parts, so it is joint-free.

If there is an engagement device, then this should preferably be firmly and rigidly connected to the lever arm. The applied leverage may be high in strong people and bending of the lever arm or breakage at the location of the engagement device should be avoided. At this point, the material is modified in certain embodiments by welds, so it is good to introduce a reinforcement at this position. For this purpose, for example, a plate is attached to the back of the lever arm. This is preferably mounted on the opposite side to the engagement device. Suitable sizes of the plates are 40 to 1 60 mm, preferably 1 00 mm in length and 1 0 to 60 mm depth, preferably 30 mm depth to the rear, and 4 to 20 mm thickness, preferably 1 0 mm thickness (corresponding to the lever arm diameter). The attached plate prevents bending of the lever arm at the fulcrum. This can happen especially when the lever arm is used improperly in the state and pulled back without lifting the foot out of the shoe. When pulling out of the stand, it should therefore be noted that the heel is simultaneously pulled up to leverage.

Preferably, the plate still contains a cavity, e.g. a circular hole. Over this, the pull-out aid can be fitted with suitable fastening devices, e.g. a chain, to be secured without damage.

A further preferred embodiment of the invention is an extension aid for taking off a snowboard or ski boot with:

a manually operated lever arm,

an upper handle member connected to the lever arm in an upper portion, and

an engagement device which is fixedly or movably connected between the upper grip element and a lower engagement element with the lever arm and which is insertable into the inner boot.

This embodiment has additional advantages. The engagement elements are attachable to the shoe outside as in the first embodiment. By the engagement device, which can engage in the inner shoe, the pivot point is displaced upward compared to the first embodiment without engagement device. The leverage forces can be applied to the inner shoe rim, so that it is attracted to the person pulling on the lever arm, while at the lower engagement element an opposite force pushes the shoe away from the body of the person. As a result of the engagement device stronger leverage forces generated and exerted greater rotational forces on the shoe, without the person must have a special arm muscles. Thus, the force that is directed downwards and strips the shoe by pressing the pull-down aid down from the foot adds another lever and torque.

As an additional effect, the inside shovel edge becomes affected by the action of the engaging device leveraged and thus widened. The Fußferse can be easily guided along the rear wall of the liner and thus easily pulled out of the shoe.

Advantageous is an embodiment in which the Hebelarmgrundkörper is round and made of stainless steel or a light metal. A diameter of 1 0 mm is hereby regularly sufficient, whereby larger diameters are also possible.

Such a second embodiment is shown by way of example in FIG. In this case, the engagement device and the lower engagement element are arranged relative to one another such that when the shoe is pulled out, the calf region of the shoe is pulled backwards by pulling on the grip element and the heel region of the shoe is pushed forward by means of the lower engagement element.

Preferably, the engagement device comprises a tab, hook or tongue which can engage in the inner shoe at the upper shoe edge. Further embodiments of the engagement device are conceivable. For example, it is possible that the engagement device is rounded or flat. It may also preferably have a slight curvature, so that it can be better inserted according to the curvature of the liner. The width of the engagement device can be adjusted according to the Innenschuhmaße.

The length of the front tongue of the engaging device can be varied and is typically between 10 mm and 1 00 mm, or 1 50 mm. Preference is given to a length of 1 5 mm to 90 mm. The nose of the engaging device should have sufficient length to be well inserted into the liner and not slip out again when using the pull-out. Good lengths are here 35 mm to 85 mm, especially 45 mm to 75 mm or preferably 50 mm or 70 mm in length. Such lengths can be used advantageously in all variants of the extension. Shorter tongue lengths and larger distances between the tongue and the Hebelarmgrundkörper have the disadvantage that there is too much play in the lever rotation, which means that the lever arm is already at an angle before the forces can act. A longer tab also has the advantage that the fabric of the liner is not too much worn out and worn when frequently used the pull-out.

In a particular embodiment, the engagement device on the Hebelarmgrundkörper extendable. Particularly good are spring mechanisms that release the engagement device on pressure and hold the engagement device in a close-fitting position on the lever arm when pressed again. Height-understandable and variable screw-engageable engagement devices are also conceivable.

The engagement device should be built so stable that it does not break off at the applied leverage. Embodiments comprising iron, stainless steel or reinforced materials have proven to be suitable. In order to better absorb the forces, the engagement device is firmly connected to the Hebelarm- or rod part body. In the alternative, inserted triangular supports or material thickening can prevent bending or breaking off of the engagement device. For wood or plastic versions, metal rails can be used for reinforcement.

Furthermore, the distance between the engaging device and the Hebelarmgrundkörper should not be too large, otherwise there is too much play in the lever movement and the lever arm is already biased before the leverage forces can act. Suitable distances are from 1 0 mm to 30 mm; better is 20 mm.

The distance of the engagement device to the inner end of the lever arm is preferably between 1 00 and 300 mm, more preferably between 1 50 and 250 mm, more preferably between 1 90 and 230 mm, most preferably 215 mm. The distance to the upper grip element is preferably between 1 50 and 350 mm, more preferably between 200 and 250 mm.

But it is also possible to fix the lever arm on the upper outer shoe via an alternative fixing mechanism, which allows the tightening in the upper portion of the Schuhrϋckens on the lever arm.

In a preferred development of the invention, the extension aid can be releasably fixed to the outer shoe with a lower engagement element. This serves in particular to stabilize the lever arm, which is attached via the lower engagement element to the outer shoe of the boot to be pulled out. As a result, a lateral slippage is avoided at the point of attack during the lever movement.

Different variants and characteristics of this fixing mechanism are possible. It is preferred that a lower engagement element forms a semicircle, which the Can embrace Schuhαußenseite. Such an option is illustrated by way of example as a half-ring body in FIG. 2. In this case, the torque can be transferred by pressure on the locked attack element on the shoe backs. At the same time, the engagement device at the top of the inner shoe edge prunes it backwards. The pivot point in this case is the lever arm between the lower engagement element and the upper engagement device. Typically, the semicircle or semi-ellipse has an opening of between 1 0 mm and 1 50 mm, preferably 50 mm and 1 20 mm. Particularly preferably, the distance of the end points of the engaging element in the form of a semicircle or a semi-ellipse of 70 mm to 95 mm, more preferably from 80 mm to 90 mm or 85 mm.

In a further preferred embodiment of the extension aid according to the invention, the lower engagement element forms a dovetail, which can embrace the outer side of the shoe. Such is exemplified in Figure 3.

Alternatively, the lower engagement element may be formed as a crescent. Reference is made to FIG. 4. This alternative is particularly advantageous if the extension aid and / or the lower engagement element are made of a lightweight material, which should have a thicker material to increase the stability. This applies in particular to the variants in which the extension aid is made of wood, so as to be lighter, for example, for use in children's ski boots and to achieve better handling. For fixation of children's shoes, the opening of the lower attack element is less wide. Typical values here are between 60 and 80 mm, or preferably 70 mm. The embodiment 4 is particularly suitable for children's boots.

Alternative formations of the lower attack element are also possible. In order to prevent the breaking out under the influence of the lever forces, these can be fixed to the outer shoe via alternative mechanisms. For example, the engagement element as a button, clip, hook or Velcro can be reversibly connected to the outer shoe.

In a very particularly preferred embodiment, the lower engagement element is formed in a V-shape. The arms of the V-shape are on Hebelarmgrundkörper attached and thereby preferably form an angle of 30 ° to 90 °, more preferably about 60 °. This arrangement according to the invention has some advantages. While some semicircular formations can only firmly grip around the ski boot backs when they have the corresponding circumference of the outer back of the ski boot, the arms of the V-shaped engagement element take the ski boot back independently of its circumference in a pincer grip and fix the shoe respectively to one of the Hebelarmgrundkörper closer or further away position. Thus, the V-shaped embodiment can be used for different shoe sizes, without the lower attack element loosely surrounds the shoe back or the shoe back does not fit into the opening of the engaging element.

The not previously discussed embodiments of the lower attack elements has in common that they can serve as a standing platform for the pull-out. Preferably, the pull-out is thus stable set up. But so that the lever can not tilt away after stopping, the Hebelarmgrundkörper in relation to the surface of the attack elements at an angle of less than 90 °. The angle is preferably between 80 ° and 88 °. Thus, the Hebelarmgrundkörper tilts slightly in the direction of the opening of the attack elements. Preferably, the handle element is slightly obliquely guided to the rear side of the lever arm and inclined in the opposite direction, as the Hebelarmgrund body.

In a preferred embodiment of the invention, the pull-out comprises two lower engagement elements, which are connected to the lever arm and can fix the outer shoe on the left and right side of the outer shoe or can be attached to two positions on Schuhrϋcken.

Such an arrangement is exemplified as trident or pitchfork variant in FIG. Here are the two lower attack elements left and right attack on the outer shoe. As a result, the lateral breaking out of the lever arm is prevented. The distance between the two attack elements should be at least 20 mm and can be up to 200 mm, depending on the shoe boot size. However, it has been shown that for most boots the distance should be less than 90 mm. In order to be able to effectively apply the lever forces on the lower outer shoe, the Points of attack are not so far apart that they are each led past the side of the shoe and thus leverage forces can no longer be exercised, except there are laterally on the side shoe two lateral stops to which the lower attack elements can be applied. The engagement elements therefore preferably have a lateral spacing of 30 mm to 75 mm, more preferably from 35 mm to 60 mm, most preferably 45 mm or 55 mm.

The trident variant has even more advantages, because many modern ski boots have on the rear outer boot a Drehverschi uss or a knob which is mounted to the rear. This rearward bulge may interfere with the attachment of the engagement elements in some embodiments. However, the attack elements are passed laterally in the trident variant of this bulge and thus can attack the outer shoe trouble-free. The distance between the attack elements can be from 32 mm to 80 mm.

In a further development with three or more attack elements, the third element can rest centrally on the spine.

It is preferred that a lower engagement element or a plurality of lower engagement elements are connected relative to the lever arm or relative to the engagement device offset to the rear with the lever arm. This is advantageous in order to be able to introduce the engagement device into the inner boot without a lower engagement element standing in the way and hindering the insertion. The distance with which the engagement device protrudes forward relative to the lever arm of a lower engagement element, or the lower engagement elements are offset relative to the engagement device or the lever arm to the rear, can be varied according to the Schuhausfertigung. A preferred distance is in this case between 1 0 mm and 60 mm. By way of example, this arrangement is shown in FIGS. 3, 5 and 6. Particularly preferred is a distance of 1 2 mm to 35 mm, most preferably 20 mm. It is important that there is enough clearance between the engagement device and the engagement elements so that the deployment aid can be inserted well into the shoe. For this purpose, depending on the shoe often at least 1 5 mm needed, preferably more than 20 mm. On the other hand, the engaging device must sit well in the shoe and not slip out during the lever movement. Therefore, the should Distance should not be more than 45 mm. Favorable for this purpose is a distance of 20 mm.

Typically, the engagement elements have a length of 30 mm to 400 mm. It has been shown that a greater length leads to stronger leverage. Therefore, these elements may preferably have 1 80 mm to 300 mm. Particularly preferred is e.g. a length of 250 mm. Compared to the shorter lengths, a better leverage is exercised.

It is preferred that the lower engaging element or elements comprise or are provided with a material suitable for not damaging or scratching the outside of the shoe when fixed and manually levered and / or provided with a non-slip surface is suitable to prevent slippage of the attack element of the ski boot.

In a preferred embodiment, the engagement device is connected as a direct continuation to the lever arm. Such an arrangement is shown by way of example in FIGS. 3, 5 and 6. This has above all the advantage of easier production. The attack elements can then be additionally mounted on the Hebelarmgrundkörper.

It has been shown in some versions with the trident variant that with very strong leverage the attack elements can be moved apart. This leads to the attack elements are pushed past the spine and no longer fix the shoe. Therefore, the engagement elements should be formed of a stable material and not be too long. In special variants, between the attack elements, e.g. halfway up a gutter, which prevents them from being pushed apart.

In order to take the different shoe sizes into account, it is favorable if the engagement device can be adjusted in position. It is therefore particularly preferred that the engagement device can be fixed in height-adjustable manner along the lever arm and / or is rotatable and / or lockable about the lever arm main axis.

Due to the height adjustment, the engagement device can always be adjusted so that it can be easily inserted into the liner. FIG. 4 shows such an arrangement. For example, in a round lever arm, the engagement device may be provided with an opening corresponding to the lever arm, into which the Hebelαrmkörper can be introduced. To lock the Eingreifvorrichtung the expert can use common means, such as a locking screw. In a lever arm base with straight surfaces, the opening of the engagement device can be adapted to these shapes accordingly. Thus, a square-shaped lever arm would have a corresponding square opening in the engaging device.

The extension aid preferably comprises two, three or more engagement devices whose extensions which can be inserted into the inner boot each have a different distance from the lever arm.

In a very particularly practical variant of the invention, these engagement devices are connected to one another. This is illustrated, for example, in version 2 in FIG. Such a Janus-headed engagement device can be used according to the required distance for insertion in the ski boot with either the one or the other head. As a result, the pull-out aid can be used, for example, for both adult and children's shoes.

It is preferred that the engagement device comprises or is provided with a material suitable for not damaging the instep, heel, innerboot, and footwear fabrics and socks when inserting the engagement device into the innerboot. Good materials here are felt, fabrics, materials with a soft and / or smooth surface, plastics, smooth wood, smooth metal, iron, brushed steel, etc.

Also material combinations are possible. Thus, the demanding tongue of the engaging device may e.g. consist of a metal, which may be thinner pronounced due to its higher bending stiffness and thus can be better introduced into the liner, while the pull-out otherwise made of wood (see Figure 4).

It is further preferred that one or more of the following elements of the extraction aid:

Lever arm, engagement device, lower attack elements, upper grip element

one or more of the following materials include:

Stainless steel, wood, steel, metal, hard plastic, plastic molded body, thermoplastic, acrylic-butadiene-styrene, polycarbonate, polyethylene terephthalate glycol or a Material which is suitable to withstand manual leverage when removing the shoe without damage.

Particularly suitable are light but stable materials that are break-resistant. Also, protective surfaces or coatings are conceivable, for example, to reduce the corrosion or oxidation sensitivity of a material.

In preferred embodiments, the extension aid is painted. Powder coatings, preferably in white or black color, have proved to be favorable. In this case, a handle is preferably attached to the lever arm after painting. This has the advantage that the lever arm at the handle end can have a small suspension device for painting, for example a hole, which is then covered by the attached handle. It is particularly preferred that the diameter of the lever arm is selected so that after the painting or coatings of the handle with a lever arm corresponding cavity is just placed on this and is firmly connected. This avoids additional sticking of the handle.

In general, the elements of the extension aid have a material diameter which is suitable for not compromising the integrity of the elements under the high leverage. Fractures or inelastic material strains must be absolutely excluded. Therefore, in preferred embodiments, the elements of the extension aid have a diameter of 5 mm to 20 mm, more preferably 8 mm to 1 5 mm, more preferably about 10 mm. However, the material thickness can also be less than 10 mm to save weight and cost. In another embodiment, one or more elements of the extraction aid are hollow inside and have a wall thickness of e.g. about 1 mm.

Furthermore, the extension aid comprises a handle element with which the lever arm can be operated manually. In a particular embodiment, the upper handle element is slightly obliquely guided by the lever arm to the rear (Figure 2). Alternatively, the handle element can be connected perpendicular to the lever arm with this (Figure 1). Finally, the gripping element at the end of the lever arm can be designed as a semicircular handle (FIG. 3). Preferably, the upper handle element is designed as a wooden handle or plastic handle or provided with a felt. The handle should be non-slip and a pleasant Have Hαptizität. Conceivable is a felt or fabric cover or finger hollows for better grip stability.

In special situations, the extension aid must also have a characteristic marking. This is especially the case in the mountain rescue, in the recovery and supply of avalanche victims or Skiunfallopfern the case. Here, the extractor can be used either to pull the shoes off very quickly and without great effort by third parties, or to gently strip the shoe, if e.g. Injuries are present. Using the leverage, the undressing succeeds without bending the foot strongly.

In such situations, the ski boot should be marked conspicuously so that it can be found immediately by the rescuers. A suitable marking is warning colors or attached phosphorescent luminous color or light emitters, which facilitate the rescue at night. It is particularly preferred to sweep the entire extension with red paint, so as to obtain a completely red pull-out.

It is also possible to form the pull-out as a ski pole, walking stick, climbing, mountain or ice ax, so that they can simultaneously act as a ski pole, hiking stick or ice ax and at the same time as a pull-out. Common ski pole or -Stockausführungen are conceivable here, which are typically used in pairs skiing or cross-country skiing, to ensure lateral stability and to allow the support.

In this case, the above floor or bar comprises one or more of the formative elements of the extension aid described above. Preferably, the ski pole, walking stick, climbing, mountain or ice ax comprises one or more engagement devices and / or lower engagement elements of the extension aid according to the invention. Advantageously, the engagement device and / or the engagement elements are in this embodiment, the ski bar itself. Thus, only an object must be taken, which can be used for both applications. This pull-out aid with ski pole is therefore particularly practical. The ordinary ski poles preferably with lower plate and / or the usual upper handles and hand straps can be used for this purpose. The Hebelarmgrundkörper is formed by the ski pole itself. However, it must be ensured that the ski pole is not under The Hebelbelαstung breaks or the material is bent. Therefore, it is possible to use stabilizing materials in the ski boot hollow body or, preferably, to use stronger materials, such as, for example, carbon materials. For this purpose, break-resistant plastic foam fillings can be used. For stainless steel or iron versions, attention must be paid to a corresponding wall thickness of the rod body. Lightweight and thin aluminum versions are therefore not suitable because the strong leverage forces can lead to bending of the material. It is a compromise between sufficient wall thickness and bar weight to meet.

The invention therefore also relates to a ski pole comprising or with an extension aid according to one of the described embodiments, as well as the use of a ski pole as a pull-out. Alternatively, the pull-out aid according to the invention may comprise a ski stick. Here, the Skistabgrundkörper replaced the lever arm or the rod part body according to the invention.

In this particular variant, the engagement device and / or the engagement elements should be as little as possible bulky and heavy and not protrude far from the bar base body; preferably not more than 50 mm, preferably less than 25 mm. For this purpose hooking or clip mechanisms which engage the shoe are advantageously used for the engagement elements, so that the engagement elements preferably protrude laterally less than 20 mm from the ski base body. Half-ring bodies with smaller openings, preferably of less than 50 mm, more preferably less than 35 mm, are also suitable (see analogous to FIG. 2). The engagement device may be a smaller tab or tongue, as described above, which also does not protrude laterally, or only slightly (less than 25 mm) beyond the ski-bar dimensions. In particular, in this embodiment, it is therefore preferred that the engagement device is extendable on the lever arm body. Particularly good are spring mechanisms that release the engagement device on pressure and hold the engagement device in a close-fitting position on the lever arm when pressed again. Height-understandable and variable screw-engageable engagement devices are also possible.

The engagement device and / or the engagement elements can in this case be arranged centrally on the ski pole or at the lower end. At the lower end, the forces are greater and the Shoe can be easily removed from the stand. For applications in the sitting position, the engagement device and / or the engagement elements can be arranged higher on the ski pole, for example in the middle or variable positionable. Decisive are the appropriate methods of application and the size of the person in order to facilitate easy removal. If the ski pole has an engagement device, then this can be positioned centrally or at a position between the end points of the ski pole or attached to the lower end.

In the particular combination design, in which one or more elements of the extension aid are attached to a ski pole, the ski plate is preferably used as an attack element. In order to grasp the ski back loosely releasable but fixing, the plate must take certain special forms that are compatible with the ski boot back. In this case, the forms of the previous embodiments can be used. Particularly suitable are simple or symmetrically double executed arcs, semicircles, half moons or V-shaped plates.

In addition, the tip should not protrude too far below the plate, because otherwise it can scratch when using the ski pole as a pull-out in the sitting position down along the ground. Short stick tips of a few centimeters are therefore preferred.

A great advantage of the present invention is generally that it is easy to handle and transport in contrast to the previous extension aids. It is lighter and less bulky than known floor tile solutions. As a result, it can easily be passed on in a group of people. In larger groups of people and especially with a larger number of children, the boots can be pulled out much faster. Even tired skiers with a full stomach do not have to bend forward enough to take off the boots and back cuffs are no longer necessary. In addition, the pull-out can be easily taken in a luggage bag and is therefore suitable for outpatient use.

The present invention also includes a method for taking off a snowboard or ski boot under the manual use of the extension aid according to the invention, comprising the following steps: α) the upper grip element is grasped with one or more hands,

b) the lever arm is attached to the shoe outer side via the lower engagement elements,

c) the extension aid is pressed down and pulled away from the shoe to the rear, the lower engagement elements remain in contact with the shoe outer side, and

d) stripping the shoe from the foot.

In this method, the removal of the shoe takes place in large part via a downward pressing force, as it is carried out analogously when removing the shoe with his hands. The pull-out aid acts as an extension arm. In addition, there is a torque that can be exerted on the lever arm on the lower part of the shoe back.

Preferably, the method further comprises prior to step b), the introduction of an engaging device at the upper shoe edge in the inner shoe, so that this engagement device in step c) remains in engagement with the liner.

In this improved embodiment of the method, stronger leverage and torques can be transmitted to the shoe. The removal of the shoe succeeds easily.

A particularly ingenious method uses the pull-out not only to take off a ski boot or snowboard boot but also to put on the shoe. It is of course possible to extend the shoe conventionally with the lever to the rear and enter. This is done even more effectively by levering the tongue forward. Here, the fabric strap is made to the tongue to use.

First, the pull-out aid is pulled through the tongue bracket in a first step. Thereafter, the engagement element, e.g. the semicircle of the second embodiment, attached to the front of the toe. In most cases, the attack elements fit on the Schuhrundung at the top, because these correspond approximately to the heel circumference.

Often is at the back of the lever arm at the junction to the engaging device a small ring or extension, which can serve as a catch for the fabric hanger. Then the lever is pulled upwards and forwards. This opens the tongue and you can easily get into the shoe.

You can also put the lever arm from above, without introducing it into the latch. Then you pull the strap using the Eingreifvorrichtung upwards.

In the trident variants, boarding also works. The lever arm is inserted or placed in such a way that the cloth hanger can be hung in the engagement device. When pulling the tongue, the engaging device pulls on the cloth hanger.

With these methods, heavy ski boots can not only be taken off, but also put on easily. The pull-out aid works like a shoehorn but with a completely new principle.

The use of the pull-out aid according to the invention is particularly suitable for snowboard boots, ski boots, winter sports shoes, mountain boots, riding boots, rain boots, rubber boots, boots, footwear, laces-free shoes, climbing shoes, inline skating shoes, ice hockey shoes, ice skates, cross country boots or other hard-to-remove shoes.

Very particularly preferred is the use of the present invention for ski boots or snowboard school. However, the extension aid according to the invention can also be used very advantageously for other shoes. Above all skating shoes or inline skating shoes often have to be pulled out in the sitting position, because otherwise they can break out when pulling out due to the rollers. In the folded seating position, however, it is particularly difficult to take off these tight-fitting shoes. Therefore, the pull-out aid according to the invention can be used particularly effectively here, because when pulling out with the lever arm, the leg can be stretched forward and thus better body lever forces are used without the person having to reach with their hands for the upper shoe edge to this at To take off.

The objects of the invention are further achieved by an additional embodiment of the invention (see also FIG. 7). This embodiment of the pull-out aid for taking off a snowboard or ski boot comprises: a manually operated rod part,

a lower engagement device formed at the lower end of the rod part,

wherein the lower engagement device is shaped so that it can embrace the upper edge of the ski boot and thereby releasably fix,

an upper handle member connected to the rod member in an upper portion.

Preferably, the lower engagement device comprises two downwardly directed extensions, wherein a first inner extension can be inserted into the inner shoe, and a second outer extension can fix the shoe on the outside. Thus, the encompassed shoe edge between the outer appendage and the inner appendage is releasably fixed. Other engagement devices that encompass the upper shoe edge are easily accessible to the skilled person.

A suitable engaging device can be achieved by removing a U-shaped recess from the lower end of the rod part. As a result, this end forms a trough into which the upper shoe edge can be inserted. This notch embraces the shoe edge. Preferably, the lower end of the rod part forms a thickening for this purpose, wherein the engagement device can be formed at the lower end of the rod part and / or the grip element in one piece with the rod part. It is favorable, e.g. the use of wood in the manufacture of this rod part, because it combines a high stability with a relatively low weight, wherein the handle element and the engagement device with the rod part can be practically milled from a piece of wood.

The rod body itself is typically somewhat stronger than in the previous embodiments and regularly has a diameter of 1, 5 cm to 5 cm, preferably 2.5 cm.

Preferably, the rod part at a distance of a few centimeters (eg 5 cm) from the handle element on a round notch. This serves to mark the end of the handle portion and a slipping of the hand from the handle portion on the Stδngenteil to prevent. Thus, the right grip position can be felt even in the dark. The grip element is advantageously characterized by a thickening at the end of the rod part. Also, the rod part between Endverdickung and notch on a round bead, which can be enclosed by the hand. This allows you to better grip the rod and push it towards the engagement device without the hand slipping off; see also FIG. 7.

This variant of the extension aid is used as an extension arm and can be used with a straight downward force to take off the shoes. The use of additional leverage is not necessary. However, by applying the forces at the rear end of the shoe, a certain rotational force will arise, which facilitates the sliding of the foot out of the shoe.

In a further method according to the invention, therefore, this extraction aid is manually introduced with one of the extensions in the shoe and fixed the upper shoe edge between the inner and outer processes. The shoe is then pushed down and / or the leg tightened. This allows the foot to be pulled out of the shoe without the person having to bend down with his hands to pull out.

This embodiment of the invention is particularly simple and inexpensive to manufacture. In addition, it is very compact and material-saving due to the straight rod shape. Due to the flat shape, the pull-out aid is easy to stow away.

In a further embodiment of the invention, the engagement device comprises a Velcro strip. Such a variant is shown in FIG. This variant is particularly easy and inexpensive to manufacture. Instead of a firmly connected or welded metal tongue, the engagement device consists of a Velcro strip. This Velcro strip is made of plastic and has on the bottom Velcro hooks, which can stick together with the Innenschuhfϋtterung. This band can also be formed from a specific tissue. It should be able to withstand high tensile forces. Advantageously, a length dimensioning of 40 to 1 50 mm on both sides of the lever arm. Thus, the Velcro tape has a total length of 80 to 300 mm. The width is between 20 and 80 mm. Particularly advantageous is a 1 60 mm long Velcro tape, which is 40 mm wide. The lever arm in this embodiment consists of a curved rod. The curve shape prevents further bending under tension. Due to the bends in the lower area it is possible to pick up the spine. The attack elements may be those as already described above. It is advantageous as attack element, the V-shape which can take as a two-pronged "crow's foot" below the shoe.

In addition, in the upper part of a plastic handle can be wound up.

The Velcro tape has an opening centrally so that it can be guided over this opening along the lever arm. The opening may contain a ring; However, it is also possible to enable a position fixed but movable suspension of Velcro on the lever arm with a simple penetration of the plastic material. The Velcro is preferably mounted movably. In the area of the puncture, or the opening ring, the Velcro material or fabric is reinforced with an additional tape.

The operation of this embodiment is surprisingly simple. To remove the ski boot, the Velcro tape is inserted into the inner lining of the shoe. The Velcro surface attaches to the liner surface. When levering the shoe, the Velcro strip is firmly connected to the inner shoe and thus acts according to the engagement device previously shown en. Thus, the shoe can be levered back. This embodiment is suitable for variable shoe sizes and very easy to manufacture in manufacture.

For further understanding of the invention, the preferred embodiments of the invention will now be explained with reference to the figures. The lengths are given in millimeters.
