    TECHNICAL FIELD OF THE INVENTION
    The invention relates to a horseshoe for horses. The horseshoe according to the invention is suitable for sport horses, in particular for race horses.
    BACKGROUND OF THE INVENTION
    The horseshoes most commonly used in the past for racehorses are usually made of aluminum. This type of horseshoe is relatively light (approx. 127 grams), but quite stiff and strong. The abrasion of the aluminum fitting is low. An aluminum shoe lasts about 5 weeks, after which the horse has to be re-shoeed. Especially because the hoof grows back.
    The disclosure document US 2010/0 276 163 A1 proposes alternatively, inter alia, a horseshoe made of fiber-reinforced plastic, which protects the horse's hoof from abrasion and is relatively light. In a variant, a plastic floor layer is additionally proposed in the cited disclosure, whereby the fiber composite material is to be protected from erosion, while at the same time the static friction on hard surfaces, e.g. Concrete or asphalt, is to be raised and the impact is to be dampened.
    In many equestrian sports, especially in racing, robust horseshoes are a basic requirement for the sport to be practiced at all, including regular and intensive training. In addition to the resistance or durability of a hoof shoe, the performance of the animal is of particular interest in sport. Fittings available today are not optimal, especially not for horse racing, because they are not very robust and / or have an adverse effect on the horse's performance, for example due to excessive weight, poor grip, sliding properties and / or damping properties.
    TASK
    It is therefore an object of the present invention to provide a horseshoe for sport horses, in particular race horses, with which the horses can achieve high running speeds. Another object of the present invention is to largely eliminate the disadvantages mentioned at the outset and to provide a horseshoe which is low in weight and has little abrasion so that it can be used or left on the hoof for as long as possible, in particular at least four weeks. Furthermore, the horseshoe should offer a good grip, prevent sinking into soft ground as much as possible and remain as free of soil material as possible. The object of the present invention is also to provide a horseshoe that can be manufactured as simply and inexpensively as possible in the factory.
    SUMMARY
    [0006] These and other objects are achieved by the features of the independent patent claims. Further developments and / or advantageous design variants of the invention are the subject of the dependent claims.
    This invention fulfills the foregoing requirements by shoeing a hoof, especially for horses, made up of a fiber-reinforced plastic material which is coated with a wear layer of plastic, the fiber-reinforced plastic material forms a core which is on the bottom side (ie on the tread side ) and is covered with the wear layer running (in particular without interruption) at least over the bottom-side (ie running surface-side) outer edge of the core (and thus of the horseshoe). The wear layer therefore runs at least over the entire running surface of the horseshoe and covers the core over the outer edge and runs up to and over the outer edge of the core. In other words, the groove layer forms at least the tread and outer edge of the horseshoe. The wear layer expediently also runs equally over the bottom inner edge of the horseshoe, whereby the wear layer covers the horseshoe over the inner edge up to the inner horseshoe edge. In other words, the groove layer forms or shapes at least the running surface, outer edge and inner edge of the horseshoe. The wear layer thus preferably forms the surface of the running surface and the outer shoe edge, expediently also the inner shoe edge. The core is preferably coated on all sides of the shoe (i.e. on the running surface side, on the hoof side and on the edge side (i.e. surfaces that connect the running surface to the surface on the hoof side, in particular on the outside and inside of the edge) or covered or encompassed on all sides by the wear layer material In the manufacturing process, the nail hole wall can also be coated with wear layer material. The core is based on or consists of a plastic fiber composite material. The core is in particular a fiber-reinforced polymer core. The core is coated with the wear layer.
    From a physical point of view, the horseshoe according to the present invention has the elementary advantage of reduced weight. In addition, the horseshoe according to the invention also has advantages from a medical and application point of view. The advantages in contrast to conventional hoof hits such as Iron and Aluminum, are the following:Less abrasion.The core and wear layer form a connection that adheres even under heavy use (under competition conditions). Better slip resistance and better slide security.Better cushioning, which results in less stress on tendons and joints.Better elasticity for the hoof's own movement. This results in a lower expenditure of energy.Less weight and therefore less inertia.Optimized movement sequence of the racehorse at a gallop.
    Preferably, the core of the horseshoe is coated at least on the tread and all of the shoe edges, preferably the core is coated on all sides.
    The core has in the front area on the bottom side depressions or through bores which are filled with the wear layer material, e.g. in order to create an improved bond between core and wear layer, which in particular increases the durability of the fitting.
    The wear layer thickness makes up on the bottom side under the core essentially at least a third, preferably at least half of the horseshoe thickness.
    In a cross section of the front area of the horseshoe, the ratio of the wear layer portion to the core portion is preferably greater than in a cross section of the rear area of the horseshoe. Furthermore, in the front area of the horseshoe (i.e. at the tip of the toe) the core is set back at least on the bottom side in relation to the hoof to be shoeed and replaced by wear layer material, which in the front area (in particular at least on the bottom side or running surface side) has a thickened wear layer a wear layer pad under the tip of the toe), preferably replacing the core material, so to speak, in order to form a thickened or enlarged wear layer edge overall on the front of the shoe. The wear layer material forms in the front area of the horseshoe front side (i.e. that area of the horseshoe which is shod under the foremost part of the hoof wall, i.e. under the tip of the toe, so to speak) a wear layer edge that is thickened compared to other edge areas of the horseshoe. In contrast, the wear layer in the rear area on the outside edges of the shoeing (i.e. those shoeing areas which are shod under the lateral parts of the hoof wall) is formed with a smaller thickness.
    The core preferably has a reduced cross-sectional dimension in the front area of the horseshoe than laterally or in the thighs, so that the core is set back (or replaced by wear layer material, so to speak) in the front area of the hoof to be shoeed in the front area of the horseshoe. So that a kind of wear layer pad is formed in the front area on the front of the horseshoe (ie under the horse's tip toe, so to speak).
    If present, depressions or through bores which are filled with the wear layer material are created in the core on the bottom side behind the beveled edge.
    The bottom surface or running surface of the horseshoe can be widened or enlarged in the front area, in particular on the jet side (i.e. towards the jet). As a result, the running surface of the horseshoe spreads in the front area, whereby the sinking or sinking depth in soft ground can be reduced.
    The plastic fiber composite of the core contains fibers which are expediently selected from the group consisting of carbon fibers (also called carbon fibers or carbon fibers), polymer fibers such as e.g. Aramid fibers (i.e., Kevlar fibers), glass fibers, and combinations thereof, with carbon fibers being preferred. The plastic fiber composite is therefore preferably a carbon fiber reinforced plastic.
    The plastic of the plastic fiber composite material of the core is preferably selected from the group consisting of thermoplastic, thermosetting plastic and combinations thereof, a thermosetting plastic being preferred.
    The plastic, i.e. the plastic matrix of the plastic fiber composite material of the core is selected in particular from the group of epoxy resins. An epoxy resin which has hardened to form a thermoset is preferred. The core thus preferably consists of a fiber-reinforced thermoset (thermoset matrix mixed with fibers).
    The wear layer is based on a plastic or consists of it.
    The plastic of the wear layer is preferably selected from the group consisting of thermosetting plastic, thermoplastic, elastomer and combinations thereof, preferably a thermosetting plastic, a thermoplastic or a combination thereof.
    The plastic of the wear layer is selected in particular from the group of the polyurethanes, in particular from the group of the thermosetting polyurethanes (i.e. crosslinked polyurethane) or the thermoplastic polyurethanes.
    The plastic of the wear layer can expediently be reinforced with plastic fibers, preferably with carbon fibers, particularly preferably with aramid fibers.
    The plastic fiber composite material of the core is e.g. made from short fibers (e.g. whiskers), which are mixed with polymers. The material can be processed using extruder or injection molding systems to form the fitting shape. Alternatively, a plate made of plastic fiber composite can be processed into the core by cutting, in particular by water jet cutting.
    A core-wear layer composite or the horseshoe can be produced by pouring or spraying the wear layer onto the core or by pressing the wear layer and core together.
    The horseshoe has essentially the shape of a U-shaped curved bar, which is optionally provided with holes for horseshoe nails.
    The inner edge of the horseshoe fitting is preferably relatively sharp-edged, in particular sharp-edged in the sense that the edge angle is preferably 90 degrees or less. If necessary, the edge angle is acute, i.e. <90 degrees, e.g. in the range of 87 to 89 degrees. The edge radius of the inner edge is preferably less than or equal to 1 mm, more preferably less than or equal to 0.5 mm, more preferably less than or equal to 0.1 mm. The sharp-edged design of the inner edge ensures a good grip on the ground and acts as anti-slip protection.
    The horseshoe according to the invention is preferably designed for attachment to the horse's hoof by means of nails. The horseshoe optionally has a central groove (fold) on the bottom, in which holes for nails for fastening to the horse's hoof are or can be made. This embodiment also provides a better grip on the ground and acts as anti-slip protection.
    The advantageous embodiment variants listed below lead, alone or in combination with one another, to further improvements of the subject matter according to the invention.
    DESCRIPTION OF THE INVENTION
    A hoof pad for horses is in particular a hoof protection which is attached to the horse's hoof, in particular from the underside of the hoof, to the hoof wall by means of a plurality of nails.
    Depending on the material, common horseshoes are very different in terms of their weight: steel: 4 × 200 g = 800 g aluminum: 4 × 127 g = 508 g carbon: 4 × 65 g = 260 g
    On the basis of model calculation based on energy balance considerations (in particular based on Appendix 3 to canter training for racing and leisure horses by Dr. Stefan Brosig, Books on Demand, Holland, 2008, ISBN 9783837026406) for racing conditions in a horse race over a distance of 2000m (one round) it is assumed that a weight reduction of 100 g when shoeing corresponds approximately to an average weight reduction of 2.3 kg in the saddle. Since the influence of the weight of the horseshoe depends heavily on the nature of the soil, a weight reduction in the saddle in the effective range of 2.6 kg to 3.8 kg is assumed for good soils and in the range of effective 1.6 kg to 2.6 kg for deep soils.
    Because of the reduced weight of the horseshoe according to the invention, the effective racing performance of a horse increases. The reasons are as follows:The power as a physical quantity describes the energy converted in a period of time in relation to this period of time. If the speed of a certain mass is to be increased, more power must be provided. However, if it is assumed that a certain horse only has a certain, i.e. can provide limited performance, the goal is to increase the speed while maintaining the same performance. This can e.g. can be achieved by reducing the mass.The available energy of a racehorse is required during a race through the acceleration and braking of the total mass, through overcoming the air resistance, through the deformation of the hoof on the ground, etc.The influence of the mass on the hoof and thus the energy consumption is 38 times greater than if the mass were on the saddle. The reason is the hoof speed (120km / h), which is included in the equation of kinetic energy as a square (2nd Newton's law, Isaac Newton, 1642–1727).
    A weight reduction of a conventional aluminum horseshoe by 50% (60 g instead of 120 g) is equivalent to a reduced weight in the saddle of approximately 9 kg. This means that over a race distance of 2000 m up to approx. 1.4 seconds could be saved if a shoe that is 50% lighter is used.
    Other speed-increasing factors in addition to the reduced horseshoe weight, which are directly related to the design of the horseshoe, in particular the structural design and / or the material of the horseshoe, are a reduction in the slip (ie the slipping backwards), a reduction in the sinking depth of the Hoof in the ground, a reduction in the adhesive force (suction force) when lifting and a reduction in the sticking when swinging the leg forward (which also has to do with the sinking depth and the grip on the ground.
    According to model calculations, a sinking depth of 1 cm less in the ground reduces the horse's energy expenditure by the same factor as if it were carrying 18.5 kg less saddle weight.
    Preventing adhesion when lifting the hooves reduces the horse's energy expenditure by the same factor as if it were carrying 5 kg less saddle weight.
    A reduction in the slip by 1 cm reduces the horse's energy expenditure by the same factor as if it were carrying 2 kg less saddle weight.
    The findings of these estimates with regard to an optimization of the horseshoe, in particular the construction of a carbon horseshoe, leads to the following consequences:
    From the above estimates it follows that with regard to the horseshoe, in addition to a weight reduction of the horseshoe, adhesion properties, sinking depths, and grip properties of the horseshoe should be considered when developing a new horseshoe in order to be able to effectively increase the performance of a horse.
    SHORT FIGURE DESCRIPTION
    Further advantages and features of the horseshoe according to the invention emerge from the following description of an exemplary embodiment of the invention with reference to schematic representations. The preferred features mentioned can be implemented in any combination - as long as they are not mutually exclusive. These show, in a schematic representation not true to scale: FIG. 1: a view of a horseshoe according to the invention, (a) shape for the forehand, (b) shape for the hindquarters; FIG. 2: Cross sections of a horseshoe according to the invention according to FIG. 1 at three different points, (a) section A-A of FIG. 1a, (b) section B-B of FIG. 1 a, section C-C of FIG. 1b; and FIG. 3: a top view of a core (without a wear layer) of a horseshoe according to the invention, (a) shape for the forehand, (b) shape for the hindquarters.
    DETAILED DESCRIPTION OF THE FIGURES
    In the following, the same reference numbers stand for the same or functionally identical elements in the same or different figures. An additional apostrophe can denote partial areas.
    In Figs. 1a and 1b, horseshoes 7 according to the invention are shown for the forehand (Fig. 1a) and for the hindquarters 9 (Fig. 1b) of horses from below or from the ground side (i.e. running surface) 11, 13. A typical horseshoe 7, 9 is partially curved with two side legs 15, 17, 19, 21 tapering to the rear and a front area 23, 25 pointing in the direction of travel connecting the legs. Corresponding to the anatomical shape of the hoof, the horseshoe 7 is for the forehand rounder and spans a larger area than the horseshoe 9 for the hindquarters, while the horseshoe 9 for the hindquarters is more elongated and spans a smaller area than the horseshoe 7 for the forehand. Hoof fittings are partially annular and can be attached to the edge of the hoof wall on the sole side. Horseshoes are expediently provided in different sizes (not shown here), so that the size of the horse's hoof can be selected according to the size of the horseshoe.
    On the bottom side (ie running surface side) horseshoes 7, 9 essentially have a partially ring-like surface 11, 13, which is designed for attachment to the hoof with a large number of square nail holes 27, 29, which are on the bottom side (ie running surface side) on the left and right the respective two legs 15 and 17 or 19 and 21 are divided along these are lined up.
    The edges of the nail holes 27, 29 are preferably broken on the bottom side, so that the nail heads can be driven in flush at the level of the tread. Optionally, a nail groove or also a furrow on the bottom side can run along the length of the leg, the nail holes being arranged within the groove or furrow. The groove or furrow increases grip and reduces the weight of the horseshoe.
    In the front area 23, 25 of the horseshoe 7, 9 is preferably beveled at its bottom front edge and forms a slope 31, 33. This is beneficial for the unhindered forward movement of the horse. The bottom edge at the ends of the legs 35, 37, 39, 41 is usually also beveled and rounded.
    In Figs. 2a, 2b and 2c three cross-sections of the horseshoes 7 and 9 are shown. FIG. 2a shows a cross section through a nail hole 27 on the left leg of the forefoot shoe 7. FIG. 2b shows a cross section in the front area of the horseshoe 7 for the forehand. Fig. 2c shows a cross section in the front area of the horseshoe 9 for the hindquarters.
    In each of the cross-sections, the horseshoe core 51 and the utility layer 53 surrounding it are shown. In FIG. 2 a, the cross section also runs over the square nail hole 27. Parts 51 ', 51' 'of the core 51 and parts 53', 53 '' of the wear layer 53 are shown on the left and right of the nail hole 27. On the bottom side (i.e. the running surface side), the wear layer 55 expediently has a thicker layer than the hoof side (i.e. the sole side). The bottom-side wear layer 55 is preferably several times thicker than the hoof-side wear layer 57. The layer thickness of the hoof-side wear layer 57 is preferably less than 2 mm, more preferably less than 1 mm. The core 51 can optionally be free of a wear layer on the hoof side. The layer thickness of the bottom-side useful layer 55 is preferably greater than 2 mm, more preferably greater than 3 mm and even more preferably greater than 4 mm. On the bottom side, the useful layer thickness 55 can in particular be a third or more, preferably half or more, more preferably approximately half of the core thickness 61. This means that the core and the bottom-side wear layer can have a similarly large or approximately the same thickness. The thickness of the core 51 can e.g. in the range from 3 to 8 mm, preferably in the range from 4 to 7 mm. The thickness of the bottom-side useful layer 55 can be in the range from 3 to 8 mm, preferably in the range from 4 to 7 mm. The thickness of the horseshoe itself is preferably in the range from 6 to 16 mm and more preferably in the range from 9 to 12 mm.
    While in the areas of the shekels 15, 17, 19, 21 the core 51 of the horseshoe 7, 9 essentially specifies the cross-sectional width and thus the ground contact area (ie the wear layer 53 on the side of the horseshoe is therefore small or small compared to the core width 63). is insignificant), the wear layer 53 protrudes clearly in the front areas 23, 25 in the direction of the running direction with respect to the core 51, so that a kind of wear layer pad 65 is preferably formed, over which the horse can repel while running. The wear layer pad can be viewed as a use view (or a thickened or enlarged wear layer edge) that is thickened or enlarged on the front outer hoof shoe edge (edge side). The thickened or enlarged wear layer edge 65, 67 has a thickness of e.g. at least 4 mm, preferably at least 5 mm, more preferably at least 6 mm. A thickness extension in the range of 4-15 mm and more preferably 5-12 mm is particularly preferred. In contrast, the wear layer thickness on the legs on the outer edge side is a maximum of 3 mm, preferably a maximum of 2 mm, thick. While the wear layer pad 65, 67 in the running direction in the horseshoe 7 for the forehand and in the horseshoe 9 for the hindquarters preferably have approximately the same dimensions; the core width 69 in the front area 25 of the horseshoe 9 for the hindquarters is preferably greater than the core width 63 in the front area 23 of the horseshoe 7 for the forehand. In addition, the core width 63 in the front area 23 of the horseshoe 7 for the forehand is smaller than the core width 63 in the area of the legs 15, 17 of the same horseshoe 7. Furthermore, the core width 69 in the front area 25 of the horseshoe 9 for the hindquarters can be larger than the core width in the area of the legs 19, 21 of the same horseshoe 9. This in order to provide the largest possible ground contact surface on the hindquarters.
    On the bottom side, as mentioned earlier, in the front area 23, 25 of each horseshoe, the bottom front edge is preferably broken or beveled. The corresponding beveled surface 31, 33 is formed in particular in the useful layer 53 or the useful layer pad 65, 67.
    On the bottom side, the inner rim 71, 73 is made as sharp as possible, so preferably not rounded. Optionally, the shoe inner edge 71, 73 can be designed with an acute angle, i.e. an angle less than 90 degrees, e.g. in the range of 89 to 85 degrees. This increases the grip of the horseshoe.
    The horseshoe outer edge 75 (laterally) in the area of the legs 15, 17, 19, 21 is expediently rounded. This prevents stumbling or falling if the horse drifts sideways.
    In Fig. 3a and 3b a preferred shape of a respective core 81, 83 of the horseshoe for the forehand and the hindquarters is shown in the bottom or tread-side view. In the front area 85, 87 of the core 81, 83, several openings or drill holes 89, 91 (preferably four openings or drill holes) are made. A wear layer to be applied to the core can connect particularly well to the core 81, 83 due to these hole structures. The mechanical compressive and / or tensile forces which act on a horseshoe are resisted by a horseshoe provided with a wear layer with such a core 81, 83 better and longer than a horseshoe without corresponding hole structures.
    A preferred horseshoe core 81, 83 according to the present invention has a concave indentation in the front area 85, 87 on the front edge 93, 95 located at the front in the running direction, instead of normally a more convex (or bulbous) shaped rounding. The indentation creates space for the application of a wear layer pad (e.g. application by spraying or pouring), which protects and supports the hoof wall on the bottom side in the front area of the finished shoe after shod at the front end of the hoof.
    The breakthroughs or drill holes 89, 91 contain holes that are more centered and others that are more arranged to the side in the front area, it is preferred that the central holes are arranged more to the rear and the side holes more to the front in the running direction are arranged. As a result, the openings or drill holes 89, 91 (corresponding to the front edge 93, 95) are preferably arranged in a line that is concave towards the front edge 93, 95.
    For reasons of weight, the horseshoe according to the invention is made of plastic or plastic fiber composite. In order to obtain particularly good strength properties paired with good grip properties and further paired with good damping properties, a composite of fiber-reinforced plastic material in the core (in particular a thermosetting plastic), e.g. Carbon fiber in an epoxy matrix, and another plastic material in the wear layer, e.g. a plastic based on polyurethane resin with or without fiber reinforcement, particularly preferred are thermoset polyurethane plastics or thermoplastic polyurethane plastics. The horseshoe according to the invention thus preferably consists of a fiber-reinforced thermoset core and a wear layer made of plastic with or without fiber reinforcement. Due to the fiber-reinforced thermoset material, the core is stiff but at the same time light. Thus, in particular, the horseshoe according to the invention is light compared to conventional horseshoes made of metal, such as iron or aluminum. The wear layer material, on the other hand, is selected in particular on the basis of its advantageous abrasion properties, in particular the wear should be low for a period of at least 4 or 5 weeks, at least so low that the wear layer during normal use (i.e. on the shod hoof) at any point during this period is rubbed off to the core. The polyurethane plastics proposed for this purpose are particularly suitable as an abrasion-resistant wear layer.
    The formation of cavities in the horseshoe, particularly in the core, could further reduce the weight and promote damping.
    To protect the hoof, horseshoes are normally attached to the tread side with nails on the outer edge of the horn part of a hoof. The horseshoes protect and support especially the edge of the hoof wall on the bottom. Due to the different functions of the horse's fore and hind limbs, the hooves of the fore quarters have a more circular shape and the hooves of the hind quarters have a pointed shape. Horseshoes are therefore shaped differently accordingly. The shape can largely be described as a U-shaped 3 / i-ring, with a running surface on the bottom and a contact surface on the hoof side. Optionally, a groove (fold) is created in the bottom of the fitting (i.e. on the running surface side), where the holes for the nails are also made. The grooves or the fold serve as anti-slip protection.
    In particular, the low weight, a certain damping effect and a less restricted blood supply in the hoof compared to conventional hoof fittings are among the advantages of the plastic fitting itself. Further advantages of the plastic fittings according to the invention over known plastic fittings which are particularly useful for racing horses are a smaller sinking depth, greater grip and reduced abrasion and wear.
    The special design for the front and rear hooves described in the figures ensures an optimal grip, reduces the sinking depth and reduces the absorption of dirt, which also leads to energy savings.
    The invention is explained below on the basis of examples.
    EXAMPLES
    Particularly good test results gave horseshoes (similar to that of test no. 5, Table 1) containing a 2 mm thick core made of carbon fiber bound in a thermosetting matrix, this core made of fiber and matrix material with a wear layer made of polyurethane, which advantageously with Aramid fibers are reinforced, is covered. This guarantees a minimum of abrasion. The lifespan is 56 weeks. The technical data of this particularly advantageous horseshoe are as follows: Core: carbon fiber in epoxy matrix (total approx. 2 mm thick) Wear layer: polyurethane with aramid fibers Manufacture: hot-pressing process (core), resp. Injection molding (wear layer) Sizes: three different sizes according to the size table (table 1) Weight: approx. 60 grams (for size 6) Application: Cold shoeing analogous to hoof shoeing made of alternative material (e.g. aluminum) Advantages: - Weight reduction by approx. 50% compared to aluminum Horseshoes- High elasticity- Optimal movement
    The horseshoes according to the invention are expediently available in prefabricated sizes. Below is a size table with sample sizes. Table 1: No. Front hoof rear hoof X in mm Y in mm X in mm 1 Y in mm 4 120 120 110 110 6 130 1130 120 120 8 140 140 130 130 X = width, Y = length
    Further test results relating to the choice of material and design options are listed in Table 2. In particular, various materials were tested for the manufacture of the core and the wear layer. Furthermore, structurally different core-wear layer composites were examined.
    In summary, the core preferably consists of a material made of carbon fibers in a thermoset matrix (e.g. epoxy resin matrix) and the wear layer preferably consists of a further thermoset (e.g. a cross-linked polyurethane) or a thermoplastic (e.g. thermoplastic polyurethane). The wear layer can optionally be reinforced with synthetic fibers (e.g. aramid fibers in a polyurethane matrix). Advantageously, the edge to the running surface on the front side of the fitting is provided with a wear layer reinforcement or wear layer pad and behind (i.e. behind the wear layer reinforcement or the wear layer pad) in the core there are pegs with wear layer material inclusions.
    While specific embodiments have been described above, it is obvious that different combinations of the possible embodiments shown can be used, provided that the possible embodiments are not mutually exclusive.
    While the invention has been described above with reference to specific embodiments, it is apparent that changes, modifications, variations and combinations can be made without departing from the spirit of the invention.
