Abstract

The strap (11, 50, 55) described is anchored at one end in the handle (3, 37) of a ski-stick while the other end, after passing at least partly round the index finger (31) of the hand gripping the ski-stick to form a loop (32, 53, 56), is attached to the handle of the stick. In this way, the ski-stick handle is linked to the hand by means of the elastically extendable strap fo form a flexible coupling. The ski-stick handle (3, 37) thus cannot slip out of the hand even when no longer held by the hand. This allows the grip exerted by the hand to be loosened and the handle released occasionally.

Description

Description: Loop arrangement for a pole grip, in particular ski pole grip.

Description

The invention relates to a loop arrangement for a pole grip, in particular a ski pole grip, with a loop band that can be anchored to the pole grip to form a closed loop.

Such a loop arrangement is known (DE 35 12 371 AI). There, a larger wrist strap and additionally a smaller wrist strap made of loop straps that are separate from each other and anchored to the stick handle are provided on opposite sides of the stick handle. Due to the commonly used wrist strap, the entire hand is pushed through before grasping the stick grip, so that the strap encloses the wrist area. Accordingly, when you release the stick handle, the stick does not fall straight to the floor but sticks to the forearm with the wrist strap. Since the wrist strap is comparatively wide with regard to slipping through with the whole hand, the wrong stick movement or due to a lack of concentration or exhaustion of the runner repeatedly causes the ski stick to slip and fall to the ground, which is not only With Loss of time and a corresponding falling back in a running competition, but in particular also with an accident risk for the runner himself and for subsequent runners, whereby the damage can go far beyond a broken stick.

The additional smaller hand strap is also unable to solve these difficulties satisfactorily. The four fingers of the hand holding the stick handle are pushed through this hand strap, ie not the thumb, the middle hand then lying in the hand strap. This hand strap is intended to improve the power transmission from the runner to the stick. In cross-country skiing with a space-consuming pole insert, the ski pole is so strongly inclined at the beginning and end that the correspondingly inclined pole grip is no longer gripped by the hand as is necessary for full direct power transmission from the hand to the pole grip. This is where the wrist strap comes into effect, which is pulled downwards from the edge of the hand, which is far from the thumb, in the direction of the stick and thereby contributes to the transmission of force to the stick. According to this function, as an alternative to the hand strap, an L-shaped hand support integrally molded onto the stick handle is provided, the projecting leg of which overlaps the back of the hand and the lower connecting leg can support the distal palm edge.

Although the known hand strap is adjustable in length, it is always so far functionally that the hand is supported only in the sense of the power transmission described above, but otherwise slides easily out of the hand strap as long as the hand is not closed or the stick handle closes. Therefore, the hand strap does not lead to a more or less firm connection between the hand (or the glove) and the stick handle, which would enable the runner to open the hand briefly without losing or disturbing displacement of the stick and its tension to loosen. An occasional loosening of the hand gripping the stick grip could prevent fatigue or even a cramp-like posture of the hand. In addition, the possibility of loosely grasping the stick handle in the no or less force Phases serving the transfer open a more harmonious stick movement in adaptation to the respective walking or running rhythm.

Accordingly, the invention is based on the object of designing the loop arrangement described at the outset in such a way that it offers the hand additional freedom of movement during the run without fear of the stick grip slipping, but rather quickly and conveniently at all times can be taken.

This object is achieved according to the invention in that the loop band forms a finger loop which receives at least one finger, in particular the index finger, and thus holds the stick handle between the thumb and the index finger in a ready position accessible by closing the hand.

The finger loop according to the invention is a narrow loop, which preferably only encloses the index finger and possibly also the middle finger - comparable to a finger ring, even if the loop band does not tightly enclose the inner phalanx over the entire finger circumference due to its anchoring to the stick handle. The finger loop leads to a kind of articulation of the ski stick in the area of its stick grip on the index finger, with the result that the ski stick can pivot relative to the hand when the hand is relaxed or open, but not out of the hand or between the thumb and the index finger formed opening of the hand slips. Therefore, the runner can loosen the hand tension during the run and open the hand more or less without fear of losing a stick and it is also guaranteed that the stick grip can be easily gripped again simply by closing the hand, possibly in Connection with a slight twist or swivel of the hand.

Tests have confirmed this result. Even without permanently closing the hand, there is an advantageous contact between the hand and the stick handle, the stick responding quickly and precisely to a slight movement of the body. Furthermore, the finger loop contributes to optimal power transmission from the stick to the floor. By the poss The change between using force and loosening results in comfortable and energy-saving handling, which at the same time gives the runner the feeling of security.

The finger strap according to the invention can be provided in connection with the usual wrist strap or replace one. It is not only suitable for a ski pole (cross-country skiing, downhill, slalom) and as a roller skate, but also for other poles such as mountain poles and the like. Both beginners and top athletes benefit from the advantages of the finger strap.

Appropriate refinements and developments result from the subclaims. These are aimed inter alia at simple manufacture and handling, additional functions, individual adaptability and easy interchangeability of the loop band.

The use of a Velcro fastener has proven to be particularly advantageous, which enables individual loop formation or loop band guidance with the hand holding the stick grip. Moreover, even with such a detachable loop fastener, it is not necessary to release the fastener again after each run, because in particular in the case of longitudinal elasticity of the loop band, the fingers can be pulled out of the finger loop and reinserted into the finger loop. It is particularly simple if the used glove remains in the finger loop or on the stick handle.

In Figure 1, only the upper end of the pole tube 2 with the pole grip 3 is shown, which is intended for the right hand. This has a shape ergonomically adapted to human hands. It can be made in the usual way from plastic, rubber, light metal or the like and optionally coated or coated, for example with cork, synthetic leather or the like. The cane tube 2 and the cane handle 3 are firmly connected to one another via an integrally molded connecting pin 4 which engages in the upper end of the cane tube 2. A conventional wrist strap 5 is also provided on the stick handle 3, of which only the two ends are shown which are wedged in the handle attachment 6, the length of the wrist strap 5 being adjusted and possibly replaced by loosening the wedge leaves. In this respect, the training corresponds to the state of the art.

As a special feature, the stick handle 3 has a vertical anchoring slot 7, which extends transversely through the stick handle 3 between its side surfaces. Possibly. the anchoring slot 7 can also have a position which deviates more or less from the vertical orientation and the exact transverse orientation. The anchoring slot 7 has a wider slot section 8 and a narrower slot section 9, which are aligned with one another in the center, so that, according to FIG. 2, two shoulders 10 are formed approximately in the center or in the axis of the pole grip 3.

In Figures 3 and 4, a loop band 11 is shown, which is elastically stretchable as a rubber band. The loop band 11 has a width corresponding to the height of the anchoring slot 7. The left end or anchoring end in the illustration is bordered by a U-shaped material strip 12 to form an eyelet 13, as shown in FIG. 4. The material strip 12 is connected to the loop band 11 by a seam 14. Possibly. a clamp connection or other connection can also be provided. Accordingly, the anchoring end of the loop band 11 has a band thickening 15. The symmetrically designed and arranged material strip 12 has projecting ends 16 over the connection point or seam 14, which ends can accordingly be pivoted, as is indicated in FIG. 4 by an arrow.

At the right end or fastening end of the loop band 11 in FIGS. 3 and 4, a Velcro strip tongue 18 is connected by means of a seam 17 or clamping, which has a first Velcro closure half 19 of a coarse structure and a narrow outer grip section 20. As can be seen from FIG. 3, the Velcro strip tongue 18 is connected to the loop band 11 with an angular deviation which can be, for example, approximately 10 ° to 20 °. The reason for this will become clear below.

Furthermore, according to FIGS. 3 and 4, a narrower additional Velcro tape 21 is attached to the loop band 11, which extends over the central region of the loop band 11 and at its end facing the anchoring end or the band thickening 15 by means of a seam 22 or through Clamping is connected to the loop band 11. The additional Velcro tape 21 has an inner Velcro strip 23 of a coarse structure and an outer Velcro strip 25 of a fine structure connected by a connecting seam 24, which is followed by a narrow grip section 26. Accordingly, as indicated in FIG. 4, the outer Velcro strip 25 can be folded over onto the inner Velcro strip 23, the two Velcro strips 23 and 25 being releasably held together in this position by the Velcro fastening effect. The meaning of this additional Velcro tape 21 will be explained later.

The loop band 11 is intended to be anchored on the pole grip 3. For this purpose, it is threaded through with the Velcro strip tongue 18 through the anchoring slot 7 from its wider slot section 8 to the narrower slot section 9, such as it illustrates arrow 27 in Figure 5. The loop band 11 cannot be pulled through completely. Rather, when threading through, the two ends 16 of the material strip 12 are folded over, the thickening 15 abutting the shoulders 10 of the anchoring slot 7 in the anchoring position according to FIGS. 5 and 6.

Despite this secure anchoring, in which the anchoring end of the loop band 11 with the material strip 12 is completely absorbed by the wider slot section 8 and no longer protrudes outward beyond the stick handle 3, the loop band 11 can be easily removed by using the flat 13 on the eyelet 13 Tool or the tip of the other ski stock a tensile force is applied. In this way, a worn loop band 11 can be exchanged for a new one, or it can also be exchanged between different loop bands 11 of different lengths or extensibility.

The loop band 11 anchored on the stick handle 3 can be attached to the stick handle 3 with its free end opposite the anchoring end. For this purpose, the handle attachment 6 is provided with a Velcro ring 29 which has a fine structure of a second Velcro half 30 assigned to the first Velcro half 19 of the Velcro tongue 18.

FIGS. 7 and 8 illustrate the function of the loop band 11. The loop band 11 anchored to the stick handle 3 is placed around the index finger 31 of the hand already resting on the stick handle 3, the loop band between the middle finger and the somewhat spread-out one, shown in FIG. 7 pointing index finger 31 is performed. Then the end of the loop band 11 is guided to the handle attachment 6 with the Velcro ring 29 and fastened to it by means of the Velcro tongue 18. The Velcro tab 18 can be continuously attached to the Velcro ring 29, so that the length or size of the finger loop 32 can be adapted exactly to the circumstances. FIG. 9 makes it clear that the angling of the Velcro strip tongue 18 with respect to the loop strip 11 causes the Velcro strip tongue 18 to extend in the fastening position in the circumferential direction of the Velcro strip ring 29, which in the fastening area anyway already has an inclination which accommodates the rising loop band course.

After fastening the Velcro strap tongue 18 to the Velcro strap ring 29 or the interaction of the respective Velcro halves 19 and 30, the hand can be released from the ski pole without loosening the Velcro strap tongue 18 from the Velcro strap ring 29. The Zeigefin¬ ger 31 can namely be pulled out of the finger loop 32, which is formed by the loop band 11 after attachment to the Velcro ring 29. Thereafter, the index finger 31 can slip back into the finger loop 32 before gripping the stick handle 3, as is indicated by the arrow 33 in FIG. 7. This pulling out or sliding in of the index finger 31 into the finger loop 32 is facilitated by the longitudinal elasticity and thus extensibility of the finger loop 32 as well as by the additional Velcro tape 21, which — with Velcro sections 23 and 25 lying one on top of the other and attached to one another — corresponding to FIG. 7 a simple removal of the loop band 11 from the stick handle 3 and thus a momentary enlargement of the finger loop 32 enables.

The index finger position in FIG. 7 does not yet correspond to the hand position when skiing, but only represents an intermediate position. According to FIG. 8, the index finger 31 (with the remaining fingers) is pivoted out of this with respect to the stick handle 3 such that the fingers only have to be closed in order to encompass the stick handle 3. It is clear that the loop band 11 encloses the index finger 31 to an increased extent, as a result of which an increased connecting effect between the index finger and the stick handle is achieved. At the same time, this pivoting process makes it clear that no rigid connection but a kind of articulation of the stick handle 3 on the index finger 31 and thus on the hand is achieved, this articulation also being present without firmly closed fingers and the stick handle 3 or the ski pole 1 having a pivoting movement within the hand incision between the thumb and index finger. Therefore, even when the hand is open, the stick does not slip from the hand, but can be safely grasped at any time by closing the hand in a functional position. An additional fixation of this position according to FIG. 8 can thereby take place that, as shown, the additional Velcro tape 21 is opened and its inner Velcro strip 23 is connected to the Velcro ring 29 in the position according to FIG. 8 - in addition to the Velcro strip 18.

According to FIGS. 7 and 8, it is provided that the loop band 11 is brought directly into contact with the index finger 31 of the bare hand. However, it is also possible for the runner to wear gloves. Then the index finger together with the corresponding glove finger is picked up by the finger loop 32.

FIG. 10 is intended to illustrate that the loop band 11 anchored on the pole grip 3 can simply be looped around the pole grip or around both pole handles of a pair of pole assemblies, the Velcro strip tongue 18 interacting with the outer Velcro strip 25 of the additional Velcro strip 21. In this way, a disruptive protrusion of the loop band 11 which is not currently required is prevented and the transportability of the stick 1 or stick pair is improved if necessary.

FIGS. 11 and 12 show an alpine pole 35 with a pole tube 36 and a pole grip 37, to which an approximately L-shaped handrest 38 with an upstanding leg 39 and a thumb rest 40 are molded or attached, as shown in FIG. FIG. 12 illustrates the support of the hand 41 with the hand edge 43 remote from the thumb resting on the lower connecting leg 42 and the thumb 44 resting on the thumb rest 40. The stick grip 37 has grooves 45 which improve grip and which have the greatest depth in the middle stick grip section and run out to the front and to the rear of the stick handle. The stick handle 37 is provided with a handle attachment 46, which carries on its upper side parallel ribs 47 which extend in an arc between the front and the rear.

This stick handle 37, like the stick handle 3 according to FIG. 1, is also provided with an anchoring slot 7 and a Velcro ring 29. An additional Velcro strip 49 is attached to the outside of the upstanding leg 39 of the hand rest 38. Accordingly, there is the possibility of optionally fastening the loop band 11 anchored in the anchoring slot 7 with the Velcro strip tongue 18 sewn onto its free end on the Velcro band ring 29 or on the Velcro strip 49. Although in the latter case it is also possible to wrap fingers with the loop band 11, the Velcro fastener 18, 49 is primarily intended for the special case that the runner wears mittens, so that it is therefore not possible to wrap individual fingers around one another.

The loop band 50 shown in FIG. 13 is fastened in the anchoring slot 7 of the stick handle in the manner already described. The loop band 50 is double-layered with a first band section 51 and a second band section 52, which on the one hand are firmly connected at the anchoring end and on the other hand merge seamlessly into one another, so that a closed finger loop 53 is formed from the outset. Their size can be adjusted in that a clamping device 54, buckle or the like which is adjustable along the loop band 50 is provided for connecting the two band layers or band sections 51 and 52. Corresponding clamping devices 54, which can be released by pressing in a part under spring tension and then displaced, are known. The finger loop 53 is shown in FIG. 13 in connection with a stick handle 3 (FIG. 1), but it is particularly suitable for the stick handle 35 according to FIGS. 11 and 12.

As FIG. 13 shows, the finger loop 53 is turned over the stick handle 3, so that it only partially encloses the index finger 31 and only completely together with the stick handle 3. Since the stick handle 3 thus keeps the finger loop 53 open, the index finger 31 can easily be inserted into the finger loop, even without the need to adjust the clamping device 54. In the case of an elastic loop band 50, the finger loop 53 can additionally be opened by pulling on the clamping device 54 or on the band sections 51 and 52 which are held on the outside. Although the loop band 50 already has a closed finger loop 53, a Velcro strip tongue 18 is in turn at the loop band end projecting outward sewn on, which can be attached to the Velcro ring 29, not shown, of the stick handle 3 in order to avoid a disturbing protrusion of the loop band 50.

The loop band 55 shown in FIGS. 14 and 15, like the loop band 50, has two layers and is provided with a finger loop 56 which is closed from the start. The size of which can be adjusted by means of a clamping stop 57 which has a release button 58 which can be pressed in against spring force. A flat ring 59 surrounding the loop band 55 prevents the clamping stopper 57 from being pulled off the loop band 55.

The loop band 55 is intended not to be put over the stick handle 3, so that the two layers of the finger loop 56 lie flat on top of one another between the stick handle 3 and the clamping stopper 57 before the index finger 31 is inserted 55 an insertion flap 60 is sewn inside the finger loop 56, which is wider than the loop band 55 and accordingly protrudes. This measure makes it easier for the index finger 31 to slip into the finger loop 56.

Another possibility for facilitating the penetration of the index finger 31 is shown in FIG. 16. A pull tab 61 is sewn to the loop band 11 there along a band edge. Corresponding tension leads, as indicated in FIG. 16, to an arching of the finger loop on the side from which the index finger 31 is to be inserted into the finger loop. This pull tab is not only suitable in conjunction with a double-layer loop band, but is particularly suitable for a single-layer loop band 11 and can replace the additional Velcro band 21 according to FIG. 7, for example.
