Description

HORSESHOES FOR HORSES

DESCRIPTIVE MEMORY

FIELD OF THE INVENTION

The present invention consists of a horseshoe for horses. Specifically, the invention proposes a horseshoe for front limbs and a horseshoe for rear limbs whose structure helps to maintain the health of the horse, minimizes the time invested by the blacksmith in adapting and installing the horseshoe in the horse's hooves and provides a good finish or quality from the aesthetic point of view.

BACKGROUND OF THE INVENTION

Horseshoes for horses are pieces that are stuck or stuck on the rims of horses' hooves. These are "U" shaped, that is, they are formed in a single piece from two branches, where each branch seen from its free end is separated into four sections called heel, fourths, shoulders and clamp.

There is a great variety of horseshoes, of different materials and styles, developed for the different types of horses and the work they do, the most commonly used materials being steel, aluminum and plastic, although some specialized horseshoes are made of magnesium, titanium or copper.

Horseshoes are used to cover the animal's hooves to prevent damage and wear to these parts and to keep intact the natural movement of the animal in any task or Circumstance and mainly in competition activities, where the hardness of the tests and of the training subjects the structure of the legs to demands that test the integrity and functionality of the animal. Therefore, the horseshoe must be adapted to both the shape and size of the helmet, being large enough and long enough for it to have the necessary support. However, before being placed correctly, it is necessary to carry out an appropriate trimming and despalme to maintain the structure, the angle and the axis of the helmets as close as possible to the normal. This has special relevance, since the inadequate practices of ironwork can induce a deformation of the helmet and can be the cause of the presentation of diverse musculoskeletal pathologies generating the shortening or cessation of the useful life of the equines. Currently, research related to the development of horseshoes for horses focuses mainly on maintaining the health of the animal. Based on recent biomechanical studies, it has been proven that overloading the extremities of the horse leads to the development of future pathologies, such as navicular syndrome, fractures, degenerative joint disease, among others, having implications for performance and lifespan in the activity performed by the horse.

In the state of the art literature it is possible to find some solutions focused on the development of horseshoes that seek to address the problem of improving the health of animals, especially horses.

For example, document US 2007289750 proposes a special horseshoe for sport horses. In this document the problem of the weight of the horseshoes that causes the animals to be subjected to very strong demands is discussed and as a result of this, the lack of mobility of the foot generates serious muscular and joint injuries. This solution is based on a horseshoe in the which on the inner surface of each of its shoulders is configured an edge area whose interior has a curved inner profile and whose width is narrower than the clip.

For its part, document WO 2006088935 states that in order to make the horseshoes more efficient in racehorses, they must be flexible to allow the heel to extend in turn that the material must be resistant to impact, to impact and a good heat insulator. In addition, the configuration of the horseshoe must be designed differently for the front legs than for the rear legs. In this way, it proposes a set of horseshoes for racehorses made of nylon with a metal toe cap embedded with relief portions in the front pieces and with a thickening portion in the upper part of the rear pieces. On the other hand, document ES 2561299 proposes a horseshoe that seeks to solve the drawbacks associated with the high degree of difficulty in the manufacture and placement of pre-designed horseshoes to maintain the mechanism of the helmet and the padding of the helmet as intact as possible . For this purpose, the horseshoe clamp comprises physical markers provided directly opposite each other both on the surface in contact with the helmet and on the surface in contact with the ground, wherein said physical markers function as a guide for cutting through the Horseshoe clamp.

Finally, EP 0899037 relates to a method for manufacturing horseshoes with clips or tabs, which attempts to overcome the disadvantages associated with the formation of unwanted thick edges. In order to avoid this drawback, a method is proposed in which during the manufacture of the horseshoe two transversely directed slits are provided, wherein at least part of the material located between said slits is pushed to form the flange. In general, these and other solutions proposed in the state of the art although they are focused on improvements associated with the manufacture of horseshoes as well as in the very design of them to benefit the health of the animals, there is a need for a solution that benefits both the blacksmith and the animal. There is also the need to have a horseshoe whose finish or terminations are adequate and provide a harmonious and symmetrical design perceptible by sight.

Another relevant point to consider is that at present it is known that there are two types of anatomical conformations more common in the previous members of horses. The first is the conformation called "encastillada" or "topina" in which the hull has a more "cylindrical" shape where its wall angles with respect to the horizontal or soil tend to be straight, that is to say that it has a narrower base. The second conformation is called "Palmiplana" in which the hulls are wider in their base of contact with the ground.

In relation to the above, it is observed that the models of horseshoes of the state of the art present a single format for helmets of previous members, which although they differentiate the right member from the left, do not consider the type of conformation of the helmet (Encastillada or Palmiplana ), aspect that turns out to be of great importance to obtain a good performance in the tasks to be developed by the horse as well as to avoid injuries and maintain its health.

This is how many of the animal's needs in terms of the characteristics that the horseshoe must have to adapt to the type of helmet and ensure its health, especially in the competitive field, are now supplied by the blacksmith himself. Such is the case, for example, of the recess that is usually made in the same for the release of pressure, which is required in the examinations of certification of blacksmiths and that is usually done manually by these, through the use of the hammer with finishes that they are not often aesthetically acceptable in terms of symmetry, roughness, brightness, among others. Also, the beveling of the edges of the horseshoe is a very common request by veterinarians to prevent injuries in sports horses. Another need is to have a horseshoe that has a constant claw and branch width to allow for the collapse in the ground to be even and not cause injuries to the animal's limb.

As mentioned above, this type of task is usually done by the blacksmith manually with a hammer and / or rasp and / or roughing machine. These tasks require that the blacksmith invest time, effort and money, costs that could be saved if it had a horseshoe that meets the needs and biomechanical needs of the animal and also provides a pleasing aesthetic to the eye ensuring quality from a Factory product.

Therefore, the object of the present invention is to provide horseshoes with formats that resemble a greater number of anatomical varieties of the helmets, to reduce the time and effort required by the blacksmith for its correct adaptation to these, thus helping maintain the health of the horse and at the same time achieving a visually more harmonious work.

DESCRIPTION OF THE INVENTION

To solve the aforementioned technical problem, the present invention consists of a horseshoe for the forelimbs and a horseshoe for the hindlimbs of a horse, which are biomechanically more respectful with the animal member. In particular for the previous members we propose a unique horseshoe model with two formats that resemble the two anatomical conformations of helmets most commonly found in horses (Encastillada and Palmiplana) and from which, it is much easier to adapt them to all helmets. The proposed horseshoe has as its first advantage that it has a suitable proportion between the width of the horseshoe and the size of the hull of the horse, being considered for the horseshoes of the previous members two different width measurements depending on the type of conformation of the case according to the anatomy of the member . This proportion results in a correct support for the animal. The horseshoe also has an improved ratio between the vertical support tab (clip) and the horseshoe itself, proposing different modalities that may include 1 and 2 clips or none, depending on the anatomy of the helmet or the function to be performed. This benefits both the horse and the blacksmith since it provides a better fixation to the helmet according to the type of conformation (anterior limbs), which is fundamental both in normal hardware as well as with the use of studs or rivets. In addition if you have to use templates, the tab is large enough to continue to fulfill its function properly with a suitable contact surface so as not to break the helmet.

In the proposed horseshoe, two characteristics associated with the perforations for the nails have been improved. First, they were placed so that they are correctly located on the white line of the horses' hooves. This is achieved by a correct proportion of the horseshoe material between the inner and outer hull area. Secondly, the perforations for the nails have a shape and angulation such that they provide a guide to achieve a good exit of the nail for its subsequent rivet. In this sense it is proposed for the two horseshoe formats for anterior limbs, piercing angles for nails (claveras) different between them to allow a placement of the nails more compatible with the angle of the helmet wall that resembles anatomically each type .

Advantageously, on the face of the horseshoe in contact with the helmet and specifically between both quarters, enough material has been removed to generate a real release of pressure in the palmar area. This prevents discomfort or pain in the most sensitive area of the helmet.

Also on the face of contact with the helmet, the horseshoe of the invention has beveled outer edges that progressively increase from the widest part of the horseshoe to the heels. This improvement advantageously decreases the chances of the horse removing the horseshoe when stepping on it with one of its other members or those of another horse and also the risk of a self-inflicted injury in case of hitting the horseshoe itself.

On the face of contact with the ground, the proposed horseshoe comprises a lower slab at the outer edge of the clamp area between both shoulders, which also has a differentiated length for each format of previous members. Advantageously, this bevel facilitates the start of the passage of the horse in the driving phase. It also helps reduce the hyperextension of both interphalangeal joints (distal and proximal), as well as reduces the tensions required in the deep flexor tendon.

The heels have also been beveled gradually to allow the sinking of these in the landing phase of the pass. With this improvement, the chances of injury are reduced in both the suspensory ligament and the superficial digital flexor tendon when sharing tensions with the deep digital flexor tendon.

In the proposed horseshoe no edge presents an angle of 90 °. All these edges are beveled, achieving a horseshoe more secure, economical in time and effort of the blacksmith, besides aesthetically harmonic. A horseshoe has also been designed in which it is ensured that the width of the clamp and of the branches is constant to allow the inferior slab to work correctly and an even collapse of the horseshoe. Advantageously, the angles of the inner side of the heels of the horseshoe do not interfere or damage the integrity of the area of the frog or padlock of the horse's hull. Also, consider their way to allow for easier cleaning.

Another feature of the present invention is that in the horseshoes of the rear members, two areas without perforating or grooving are provided in the shoulders to facilitate the drilling of holes for studs or studs. This area, as it does not have the material cast traditionally made, provides a better and safer fixation for the frequently used elements to improve traction and avoid skidding. In addition, by preventing an excessive decrease in the material of the horseshoe, it is possible to increase the resistance of the same and therefore prolong its useful life in the horse. The horseshoe of the present invention has been advantageously designed in such a way that in its modality for hind limbs, it is asymmetrical in its branches, in other words, the dimensions and proportions of the left branch are different from those of the right branch with the object of fitting in a better way to the hull of the horse, thus respecting its anatomy, maximizing the effectiveness of the step and diminishing the injuries. Finally, the proposed horseshoes that are described in more detail later, will advantageously have different "sizes" or "numbers" for different sizes of horse hulls, in which, only the thickness of the horseshoes and the rest of the horseshoes remain constant. dimensions vary proportionally among them being this an improvement to maintain the constant proportion between the different sizes of helmets and horseshoes. In this way if it is required to manufacture a horseshoe for a certain size of a horse helmet, it is enough to obtain the measurement of a single parameter and by means of this value the other measures are obtained with the exception of the thickness based on a previously established and standardized proportion . This allows to obtain horseshoes suitable according to the size of the horse hulls that maximize their performance and at the same time reduce the work of adaptation or modification by the blacksmith.

DETAILED DESCRIPTION OF THE FIGURES

According to Figures 1 to 6b, there is a horseshoe for front members 100 of a horse made up of two branches 110 joined by their front area or clamp 120. The horseshoe for front members 100 illustrated in Figure 1 has an upper face 101 flat and a concave upper recess 121 of smaller width and thickness than the branches 1 10, which extends on part of the inner edge of the horseshoe, specifically throughout the area of the tweezers 120, shoulders 120a and fourths 120b.

Additionally, the upper face 101 of the horseshoe, specifically in the area adjacent the upper recess 121 of the shoulder area 120a and fourth parts 120b comprises perforations 122 spaced equidistantly in each branch 110 and preferably rectangular in shape.

Following with Figure 1, the horseshoe has the ends of the heels 103 angulated by a chamfer, so that the outer edge of the heels 103 has a greater length than the inner edge. This configuration adapts to the anatomy of the animal, specifically to the area of the frog legs. According to Figure 3, the perforations 122 are located inside a groove 123 formed in the lower face 11 1 of the horseshoe, which has a first interior wall 124 and a second interior wall 125, both angled to adapt to the angled shape of the head of the nails and to direct the nails towards the correct position in the hull of the horse, further configuring in said second inner wall 125 closer to the outer edge of the horseshoe, interior recesses 126 that connect the bottom edge of the slot 123 with each perforation 122. Preferably, the inner recesses 126 have a trapezoidal shape to guide the nails convergently towards the perforations 122 during the process of installing the horseshoe and to fix them to the interior of the channel so that there is no Relative movement or "play" between the nail and the horseshoe. Figure 4 illustrates the section A-A shown in Figure 3, in which the angle α formed between the horizontal and the projection line of the nail between the angled inner walls (124, 125) of the channel is observed, providing a guide to achieve an appropriate exit of the nail that is inserted in each perforation 122. Preferably, the values of the angle α are comprised in the range between 80 ° and 87 °, with 82 ° and 85 ° being the preferred values. According to a preferred embodiment of the invention, the horseshoe for front members 100 comprises four perforations 122 located in each groove 123 that is configured in each branch 110.

As seen in Figures 1 and 2, the horseshoe for front members 100 comprises a bevel 130 extending from the inner edge of the horseshoe, specifically from each end of the upper recess 121 and running the entire outer perimeter of the latter. In addition, the bevel comprises a steeper zone 131 at the ends of the heels of each branch 110. Similarly and as seen in Figures 2 and 3, the horseshoe further comprises in the anterior area of the lower face 11 1, specifically in the area of the tweezers 120, a roughing lower 132 located forward of the slots 123. In addition, all the lower vertices of the horseshoe are rounded, thus avoiding the 90 ° angles.

According to the embodiment illustrated in Figure 5a, the horseshoe for front members 100 comprises a flange 140 or vertical support clip which preferably consists of a body of triangular section with rounded top vertex. The flange 140 is located on the leading edge of the upper face of the clamp 120. Preferably, the configuration of the flange 140 is equilateral and its thickness is greater in the base than in the upper end. In addition, the ratio between the width and height of the clip is preferably 3: 2.

According to the embodiment illustrated in Figure 5b, the horseshoe for front members 100 comprises two flanges 140 as described above, which are located on the outer edge of the upper face of each branch 110, where preferably the midpoint of the eyelashes 140 coincides with the midpoint of separation of the central perforations 122.

Figures 6a and 6b show two examples of configurations that the horseshoe can adopt for previous members of the present invention which have been developed for reasons of resembling and being functional to the two types of anatomical conformations of helmets more common in horses (Encastillada and Palmiplana).

First, a horseshoe was constructed as illustrated in Figure 6a which corresponds to a horseshoe of the "palmiplana" type, which has a length of 144 mm, a width of 145 mm and a height of 8 mm. This configuration has a width of branches and clamp p of 23 mm, a width of recess greater than _r of 10 mm, a length of upper recess L of 84 mm and a depth of recess greater than 2 mm. The distance d between the anterior perforations of each shoulder is 83 mm and the minimum distance s between the inner vertexes of the heels is 59 mm. The chamfered edge of both heels forms an angle β of 31 °. In addition, the separation of the perforations of each branch is 21 mm. Following the configuration illustrated in Figure 6a, it is found that the bevel (130, Fig. 1) was made with a pronounced 4 mm high heel area (103, Fig, 1). For its part, the lower roughing (132, Fig. 3) has a height of 4 mm and a maximum length of 10 mm in the center of the clamps.

Secondly, the horseshoe of Figure 6b corresponds to a horseshoe of the "Encastillada" type, which was manufactured with a length 1 of 150 mm, a width of 139 mm and a height of 8 mm. This configuration has a width of arms and clamps p of 22 mm, a width of recess greater than _r of 9 mm, a length of upper recess l _r of 82 mm and a depth of recess greater than 1, 5 mm. The distance d between the anterior perforations of each shoulder is 73 mm and the minimum distance s between the inner vertices of the heels is 61 mm. The chamfered edge of both heels forms an angle β of 40 °. In addition, the separation of the perforations of each branch is 21 mm.

Following the configuration illustrated in Figure 6b, it is found that the bevel (130, Fig. 1) was made with a pronounced 4 mm high heel area (103, Fig. 1). For its part, the lower roughing has a height of 4 mm and a maximum length of 9 mm in the center of the clamps.

In the modalities of the horseshoe comprising flanges, these were considered to have a width of 30 mm, a height of 20 mm, a base thickness of 2 mm and an upper end thickness of 1 mm.

The dimensions described above are maintained on a proportional scale in the size variation between the "sizes" or "numbers" of horseshoes for horses.

Figures 7 to 9 illustrate a horseshoe for rear members 200 of a horse made up of two branches 210 joined in their front area or clamp 220, which according to the The embodiment illustrated in Figure 7 has a flat upper face 201 and a concave upper recess 221 of smaller width and thickness than the branches 210, which extends over part of the inner edge of the horseshoe, specifically throughout the area of the clamps 220 , shoulders 220a and fourth parts 220b.

Unlike the horseshoe for front limbs 100, shoulders 220a of the horseshoe for rear members 200 comprise a straight portion 202 which provides a shape more suitable for the anatomy or shape of the hind legs of the horse.

Like the horseshoe for front limbs 100, the horseshoe for rear members 200 also comprises on the upper face 201, specifically in the area adjacent to the upper recess 221 of the fourth parts 220b, perforations 222 with a preferably rectangular shape. However, it comprises an undrilled or grooved zone 226 which produces a separation between a group of perforations 222 and an insulated perforation 227.

According to Figure 7, the horseshoe has the ends of the heels 203 angled by a chamfer, so that the outer edge of the heels 203 has a greater length than the inside edge. This configuration adapts to the anatomy of the animal, specifically to the area of the frog legs.

According to Figure 8, the group of perforations 222 is located inside a slot 223 formed in the lower face 211 of the horseshoe, which has a first interior wall (not shown) and a second interior wall 225 , both angled to adapt to the angled shape of the head of the nails and to direct the nails towards the correct position in the case of the horse, also configuring in said second inner wall 225 closer to the outer edge of the horseshoe, interior recesses 229 that connect the lower edge of the slot 223 with each perforation. Preferably, the inner recesses 229 have trapezoidal shape to guide the nails convergently towards the perforations during the process of installing the horseshoe and to fix them to the interior of the channel so that there is no relative movement or "play" between the nail and the horseshoe. For its part, the insulated perforation 227 is located inside an insulated slot 228 separated from the slot 223 and closer to the front edge of the shoe, which also comprises a first interior wall and a second interior wall, both angled and an interior recess is configured in one of them. The perforations of the horseshoe for the hind limbs are also shown in Figure 4, in which the angle α formed between the horizontal and the projection line of the nail between the angled inner walls of the grooves is observed, where the angle values α are in the range of between 80 ° and 87 °, with 85 ° being the preferred value.

According to a preferred embodiment of the invention, the horseshoe for rear members 200 comprises a group of three perforations 222 located in each slot 223 that is configured in each branch 210.

As seen in Figure 7, the horseshoe for rear members 200 comprises a bevel 230 extending from the inside edge of the horseshoe, specifically from each end of the upper recess 221 and running the entire outer perimeter thereof. In addition, the bevel comprises a steeper zone 231 at the ends of the heels of each branch 210. Similarly and as seen in Figure 8, the horseshoe for rear members 200 also comprises in the anterior area of the lower face 211, specifically in the region of the clamp 220, a lower slab 232 which is configured in front of the insulated slot 228. Furthermore, all the lower vertices of the horseshoe are rounded, thereby avoiding the 90 ° angles.

According to the embodiment illustrated in Figure 9, the horseshoe for rear members 200 comprises two flanges 240 or vertical support clip each consisting of a body of triangular section with a rounded top apex. The 240 tab are located on the edge exterior of the upper face of the branches 210, preferably in the non-perforated or grooved zone 226 of each branch 210. Preferably, the configuration of the flange 240 is equilateral and its thickness is greater in the base than in the upper end. In addition, the ratio between the width and height of the clip is preferably 3: 2.

Preferably, in the horseshoe for rear members 200 the elements of a branch 210 may have different dimensions or proportions with respect to those of the opposite branch 210, whose purpose is to adapt to the anatomy or shape of the horse's rear hooves, which are asymmetrical on its flanks. In this manner and according to the present invention, the configuration of the branches of a horseshoe for the right rear member will have an opposite configuration to a horseshoe for the left hindlimb. According to the above, the example of figure 10 illustrates a bottom plan view of the configuration of a horseshoe for the right rear member, which has a length of 1 of 143 mm, a width of 139 mm and a height of 8 mm. This configuration has a width of branches and clamp p of 23 mm, a width of upper recess of 10 mm, a length of upper recess of 86 mm and a depth of upper recess of 1.5 mm. The distance d between the isolated perforations of each shoulder is 71 mm and the minimum distance s between the shoulder heels is 67 mm. The chamfered edge of both heels forms an angle β of 30 ° between them. In addition, the separation ri of the group of perforations of the lateral branch is of 15 mm whereas the separation r ₂ of the group of perforations of the medial branch is of 16 mm (reverse configuration in horseshoe for left posterior member). The gap ji between the perforation located later with the isolated perforation of the lateral branch is 32 mm, while the separation j ₂ between the perforation located later with the isolated perforation of the medial branch is 33 mm (inverse configuration in horseshoe for left hind limb). The bevel of this horseshoe was made with a pronounced 4 mm high area. For its part, the lower roughing has a height g of 4 mm and a maximum length of 8 mm in the center of the clamps.

In the modality of the horseshoe comprising flanges, these have been manufactured with a width of 30 mm, a height of 20 mm, a base thickness of 2 mm and an upper end thickness of 1 mm.

As for the horseshoes of previous members, the dimensions previously described allow to standardize the manufacturing process of the horseshoes and obtain a proportional scale in the variation of size between the "sizes" or "numbers" of horseshoes for horses.
