Description

description

Technical field of the invention The invention relates to a shoe for horses. The hoof fitting according to the invention is suitable for sport horses, in particular for racehorses.

Background of the Invention Horseshoes for racehorses, most commonly used in the past, are usually made of aluminum. This type of shoeing is relatively light (about 127 grams), but quite stiff and firm. The abrasion of the aluminum fitting is low. An aluminum fitting lasts about 5 weeks, after which the horse must be re-fogged. This especially because the hoof grows.

The disclosure US 2010/0 276 163 A1 proposes, inter alia, a shoeing made of fiber-reinforced plastic, which protects the horse's hoof from abrasion and is relatively easy. In a variant, a plastic bottom layer is additionally proposed in the mentioned disclosure, whereby the fiber composite material is to be protected against erosion, at the same time the static friction on hard ground, such as. Concrete or asphalt, to be increased and the serve should be damped.

In many equestrian sports, especially in racing, resistant hoof fittings are a prerequisite, for that the sport can be operated at all, this includes regular and intensive training. In addition to the durability or durability of a horseshoe, the performance of the animal is of particular interest in sport. Today available fittings are not optimal, especially not for the horse racing, as they are on the one hand too little resistant and / or adversely affect the performance of the horse, for example, by excessive weight, unfavorable traction, sliding properties and / or damping properties.

OBJECT It is therefore an object of the present invention to provide a horseshoe for sport horses, in particular racehorses, with which the horses can achieve high running speeds. It is another object of the present invention to largely remedy the disadvantages mentioned above and to provide a shoe fitting, which has low abrasion at low weight, as long as possible, especially for at least four weeks, can be used or left on the hoof. Next, the shoe fitting should provide a good grip, prevent sinking in soft ground as possible and remain as free of soil as possible. It is also an object of the present invention to provide a horseshoe fitting that is as easy to produce as possible from the factory.

Summary These and other objects are achieved by the features of independent claim 1. Further developments and / or advantageous embodiments of the invention are the subject of the dependent claims.

[0007] This invention meets the foregoing requirements by providing a hoof fitting, in particular for horses, constructed of a fiber reinforced plastic material coated with a plastic wear layer, the fiber reinforced plastic material forming a core which is bottom (ie, tread side). and at least on the bottom side (ie tread-side) outer edge of the core (and thus of the horseshoe) extending (in particular without interruption) is covered with the wear layer. The wear layer thus runs at least over the entire tread of the horseshoe and covers the core over the outer edge and extends to and over the outer edge of the core. In other words, the wear layer forms or forms at least the tread and outer edge of the horseshoe. Conveniently, the wear layer extends equally over the bottom-side inner edge of the horseshoe, whereby the wear layer covers the shoe fitting on the inner edge except for the inner Hufbeschlagsrand. In other words, the wear layer forms or forms at least the tread, outer edge and inner edge of the horseshoe. The wear layer thus preferably forms the surface of the tread and the outer Hufbeschlagsrands, expediently also the inner Hufbeschlagsrands. Preferably, the core is on all hinge sides, i. tread-side, hoof-side and edge-side, (i.e., surfaces which connect the tread to the hoof-side surface, in particular on the outside at the edge and on the inside at the edge) or coated on all sides or covered on all sides by the wear-layer material. Depending on the production process, the nail hole wall may 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.

The shoe fitting according to the present invention brings in physical terms the elementary advantage of a reduced weight. In addition, the inventive shoe fitting also brings advantages in terms of medical and application technology. The advantages in contrast to conventional hoof fittings, such. Iron and aluminum, are the following: • Less abrasion. • Core and wear layer form a bond, which is also liable under heavy use (under competition conditions). • Better slip resistance and better sliding safety. • Better cushioning, resulting in less stress on the tendons and joints. • Better elasticity for the proper movement of the hoof. This results in a lower energy consumption. • Less weight and therefore less inertial mass. • Optimized movement of the racehorse in a gallop.

Preferably, the core of the horseshoe is coated at least on the tread and all fitting edges, preferably, the core is coated on all sides.

The core has in the front region at the bottom recesses or through holes, which are filled with the wear layer material, e.g. to thereby produce an improved bond of core and wear layer, which in particular increases the durability of the fitting.

The wear layer thickness makes the bottom side under the core substantially at least a third, preferably at least half, the Hufbeschlagsstärke.

In a cross section of the front portion of the horseshoe, the ratio of wear layer portion to core portion is preferably greater than in a cross section of the rear portion of the horseshoe. Furthermore, in the front region of the horseshoe (ie at the toe tip), the core is set back at least on the floor opposite the hoof to be studded and replaced by wear layer material, which thereby has a thickened wear layer (or a wear side) in the front area (especially at least on the floor or tread side) Wear layer pad under the toe tip) forms, preferably the core material, so to speak replaced, to form hufbeschlagsvorderseitig a total thickened or enlarged wear layer edge. The wear layer material forms a wear layer edge in front of the front of the shoe fitting (i.e., that shoeing portion that is fogged under the foremost part of the hoof wall, i.e., under the tip of the toe, as it were) under the toe edge of the shoe. On the other hand, the wear layer is formed at the rear of the outside horseshoe side edges (i.e., those horseshoe areas that are misted under the lateral parts of the hoof wall) with a smaller thickness.

The core preferably has in the front region of the horseshoe on a reduced cross-sectional extent than the side or in the legs, so that the core is set against the hoof to be beaten in the front region of the horseshoe against the wear layer (or replaced so to speak by wear layer material) so that a kind of wear layer pad in the front area on the front of the horseshoe (ie, so to speak, under the toe of the horse) is formed.

If present, depressions or through holes, which are filled with the wear layer material, applied in the core bottom side behind the beveled edge.

The bottom surface or running surface of the horseshoe can be widened or enlarged in the front region, in particular on the beam side (i.e., towards the jet). This spreads in the front area of the tread of the horseshoe, whereby the sinking or the sinking depth can be reduced in soft soil.

The plastic fiber composite of the core includes fibers suitably selected from the group consisting of carbon fibers (also called carbon fibers or carbon fibers), polymer fibers such as carbon fibers. Ara-midfasern (i.e., Kevlar fibers), glass fibers, and combinations thereof, with carbon fibers being preferred. The plastic fiber composite is thus 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, thermoset and combinations thereof, with a thermoset is preferred.

The plastic, i. the plastic matrix of the plastic fiber composite material of the core is in particular selected from the group of epoxy resins. Preference is given to an epoxy resin which has cured to give thermosetting plastic. The core thus preferably consists of a fiber-reinforced thermoset (Duroplastmatrix offset with fibers).

The wear layer is based on or consists of a plastic.

The plastic of the wear layer is preferably selected from the group consisting of thermoset, thermoplastic, elastomer and combinations thereof, preferably a thermoset, a thermoplastic or a combination thereof.

The plastic of the wear layer is in particular selected from the group of polyurethanes, in particular from the group of thermosetting polyurethanes (i.e., crosslinked polyurethane) or thermoplastic polyurethanes.

The plastic of the wear layer may conveniently be reinforced with plastic fibers, preferably with carbon fibers, more preferably with aramid fibers.

The plastic fiber composite material of the core is e.g. made of short fibers (e.g., whiskers) blended with polymers. The material can be processed to form the fitting form via extruder or injection molding equipment. Alternatively, a plate made of plastic fiber composite by cutting, in particular by water jet cutting, are processed to the core.

A core-wear layer composite or shoeing can be prepared by the wear layer is poured or sprayed onto the core or by the wear layer and core are pressed together.

The horseshoe has substantially the shape of a U-shaped bar, which is optionally provided with holes for horseshoe nails.

The inner edge of the shoe horseshoe is preferably relatively sharp, in particular sharp-edged in the sense that the edge angle preferably has 90 degrees or less. Optionally, the edge angle is acute-angled, that is <90 degrees, e.g. in the range of 87 to 89 degrees. Preferably, the edge radius of the inner edge is 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 bottom or acts as anti-slip.

The inventive horseshoe is preferably designed for attachment to the horse's hoof by means of nails. The shoeing optionally has a bottom groove (fold) on the bottom, in which holes are inserted for nails for attachment to the horse's hoof or can be. This embodiment also serves a good better bottom grip or acts as anti-slip.

The below-mentioned advantageous embodiments lead alone or in combination with each other to further improvements of the inventive article.

DESCRIPTION OF THE INVENTION A shoe for horses is in particular a hoof protection, which is attached to the horse's hoof, in particular from the hoof underside on the hoof wall by means of a plurality of nails.

Depending on the material common hoof fittings are very different in weight: - Steel: 4 x 200 g = 800 g - Aluminum: 4x127 g = 508 g - Carbon: 4 χ 65 g = 260 g Based on model calculations on energy balance considerations (in particular, based on Appendix 3 to Racing and Recreational Horse Gallop Training by Dr. Stefan Brosig, Books on Demand, Holland, 2008, ISBN 978-3-83702-640-6) for race conditions in a gallop race over a distance of 2000 m (one lap) it is assumed that a weight reduction of 100 g in the horseshoe gear corresponds to an average weight reduction of 2.3 kg in the saddle. Since the influence of the weight of the horseshoe depends very much on the condition of the soil, effective soils will have a weight reduction in the saddle in the range of effectively 2.6 kg to 3.8 kg and in deep soils in the range of effectively 1.6 kg 2.6 kg assumed.

Due to the reduced weight of the inventive Hufbeschlags increases the effective racing performance of a horse. The reasons are as follows: The power as a physical quantity denotes the energy converted in a time span in relation to this time span. If the speed of a certain mass is to be increased, more power must be provided. However, it is assumed that a particular horse will only receive a certain, i. Limited performance, the goal is to increase the speed while maintaining the same performance. This can e.g. be achieved by reducing the mass.

The available energy of a racehorse is required during a race by the acceleration and the braking of the total mass, by overcoming the air resistance, by 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 would be on the saddle. Reason is the hoof speed (120 km / h), which is quadratic in the equation of the kinetic energy (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 about 9 kg. This means that a race distance of 2000 meters could save up to about 1.4 seconds when using a 50% lighter hoof fitting.

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 of the slip (ie slipping backwards), a reduction in the sinking depth of Hoof in the ground, a reduction in the adhesion force (suction) when lifting and a reduction in the sticking when forward swinging of the leg (which also has to do with the sinking depth and traction).

According to model calculations, a sinking depth of 1 cm less in the ground reduces the energy expenditure of the horse by the same factor as if it carried 18.5 kg less saddle weight.

Preventing the adhesion when lifting the hooves reduces the horse's energy expenditure by the same factor as if it carried 5 kg less saddle weight.

A reduction of the slip by 1 cm reduces the horse's energy expenditure by the same factor as if it carried 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 Hufbeschlags, leads to the following consequences: From the above estimates follows that with respect to the horseshoe in addition to a weight reduction of the horseshoe and adhesion properties, sinking depths and handle properties of the horseshoe should be considered in the development of a new horseshoe to effectively increase the horse's performance.

BRIEF DESCRIPTION OF THE DRAWINGS Further advantages and features of the horseshoe according to the invention will become apparent from the following description of an embodiment of the invention with reference to schematic illustrations. Said preferred features can be realized in any combination - unless they are mutually exclusive. It shows in not to scale, schematic representation:

DETAILED DESCRIPTION OF THE FIGURES Hereinafter, like reference numerals indicate like or functionally identical elements in the same or different figures. An additional apostrophe can denote areas of tea.

In FIGS. 1a and 1b, hoof fittings 7 according to the invention for the forequarters (FIG. 1a) and for the hindquarters 9 (FIG. 1b) of horses from below or from the bottom side (ie running surface) 11, 13 are shown , A typical Hufbeschlag 7.9 is partially ring-shaped bent with two expiring to the rear lateral legs 15, 17, 19, 21 and a pointing in the direction of the leg connecting front portion 23, 25. According to the anatomical hoof shape of the shoe fitting 7 for the forehand rounder and spans a larger area than the hoof fitting 9 for the hindquarters, while the hoof fitting 9 is elongated for the hindquarters and spans a smaller area than the hoof fitting 7 for the forequarters. Partial ring-shaped hoof fittings are sole side fastened to the hoof wall edge. Horseshoes are conveniently provided in various clothing sizes (not shown here), so that the size of the horse's hoof can be chosen according to a matching or shaped hoof fitting.

Hufbeschläge 7, 9 substantially on the bottom side (ie running surface side) on a part-ring-like surface 11, 13, which is designed for attachment to the hoof with a plurality of square nail holes 27, 29, which on the bottom side (ie running surface side) left and right on the respective two legs 15 and 17 or 19 and 21 divided, are lined up along this.

The edges of the nail holes 27, 29 are preferably broken on the bottom side, so that the nail heads can be taken flush at tread level. Optionally, a nail groove or furrow on the bottom side, run rule-kangängsorientiert, the nail holes are arranged within the groove or furrow. The groove or furrow increases the grip and reduces the weight of the horseshoe.

In the front region 23, 25 of the shoe fitting 7, 9 is preferably bevelled at its bottom-side leading edge and forms a slope 31,33. This is beneficial for the unimpeded locomotion of the horse forward. The bottom-side edge at the ends of the legs 35, 37, 39, 41 is usually also bevelled 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 Vorderhufbeschlags 7. Fig. 2b shows a cross section in the front region of the horseshoe 7 for the forehand. Fig. 2c shows a cross section in the front region of the horseshoe 9 for the hindquarters.

In each of the cross sections of the hoop core 51 and the surrounding wear layer 53 are shown. In Fig. 2a, the cross section also extends beyond the square nail hole 27 away. 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. At the bottom (i.e., tread side), the wear layer 55 desirably has a greater layer thickness than the hoof side (i.e., sole side). Preferably, the bottom-side wear layer 55 is several times thicker than the wear side wear layer 57. The layer thickness of the wear side wear layer 57 is preferably less than 2 mm, more preferably less than 1 mm. Optionally, the core 51 can be free of wear on the hoof side. The layer thickness of the bottom-side wear 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 wear layer thickness 55 can be in particular one third or more, preferably half or more, more preferably approximately half of the core thickness 61. This means that core and bottom-side wear layer can have a similar or approximately the same thickness. The thickness of the core 51 may be e.g. in the range of 3 to 8 mm, preferably in the range of 4 to 7 mm. The thickness of the bottom-side wear layer 55 may be in the range of 3 to 8 mm, preferably in the range of 4 to 7 mm. The thickness of the horseshoe itself is preferably in the range of 6 to 16 mm and more preferably in the range of 9 to 12 mm.

While in the areas of the legs 15, 17, 19, 21 of the core 51 of the horseshoe 7, 9 essentially specifies the cross-sectional width and thus the ground contact surface (ie the wear layer 53 laterally of the horseshoe compared to the core width 63 low or is insignificant), projects the wear layer 53 in the front region 23,25 in the direction of travel against the core 51 clearly before, so preferably a kind of wear layer pad 65 is formed over which the horse can repel while running. The wear layer pad can be regarded as a useful view (or thickened or enlarged wear layer edge) which is thickened or enlarged at the front outer horseshoe edge (edge). The thickened wear layer edge 65, 67 has a thickness extent of e.g. at least 4 mm, preferably at least 5 mm, more preferably at least 6 mm. In particular, a thickness expansion in the range of 4-15 mm and more preferably of 5-12 mm is preferred. In contrast, the wear layer thickness at the outer edge of the legs 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 approximately the same dimensions, the core width 69 in the front portion 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, where appropriate, the core width 63 in the front portion 23 of the horseshoe 7 for the forehand less than the core width 63 in the region of the legs 15, 17 of the same horseshoe 7. Further, the core width 69 may be formed larger in the front portion 25 of the horseshoe 9 for the hindquarters as the core width in the region 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 already mentioned, in the front region 23, 25 of each horseshoe, preferably the bottom-side leading edge is broken or chamfered. The corresponding chamfered surface 31, 33 is formed in particular in the wear layer 53 or the wear layer pad 65, 67.

On the bottom side, the horseshoeing inner edge 71, 73 is made as sharp as possible, that is preferably not rounded. Optionally, the horseshoe inner edge 71, 73 can be made at an acute angle, i. an angle less than 90 degrees, e.g. ranging from 89 to 85 degrees. This increases the grip of the horseshoe.

The Hufbeschlagsaussenkante 75 (side) in the region of the legs 15, 17, 19, 21 is conveniently rounded. This prevents tripping or falling in lateral drifting of the horse.

In Fig. 3a and 3b, a preferred form of a respective core 81, 83 of the horseshoe for the forequarters or the hindquarters in the bottom-side or tread-side view is shown. In the front region 85, 87 of the core 81, 83 a plurality of openings or boreholes 89, 91 (preferably four openings or boreholes) are created. A wear layer to be applied to the core can be particularly well connected to the core 81, 83 due to these hole structures. The mechanical pressure and / or tensile forces, which act on a shoe fitting, resists a provided with a wear layer shoe fitting with such a core 81, 83 better and longer than a shoe fitting without corresponding hole structures.

A preferred hoop fitting core 81, 83 according to the present invention has a concave-shaped indentation in the front region 85, 87 at the front forward edge 93, 95 in the forward direction, rather than normally a more convex (or bulbous) shaped curve. The indentation provides space for the application of a wear layer pad (for example, application by spraying or pouring), which protects and supports the hoof wall at the front of the finished horseshoe after misting the hoof at the front end of the hoof.

The apertures or boreholes 89, 91 include holes which are more central and others which are located laterally in the front region, in which case it is preferred that the central holes are located farther back and the lateral holes are more forward in the running direction are arranged. This results in that the openings or boreholes 89, 91 (corresponding to the front edge 93, 95) are preferably arranged in a line which is concave in the direction of the front edge 93, 95.

For reasons of weight of the invention Hufbeschlag made of plastic or plastic fiber composite is produced. In order to obtain particularly good strength properties, coupled with good grip properties and further coupled with good damping properties, in particular a composite of fiber-reinforced plastic material in the core (in particular a duroplastic), 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 hoof fitting according to the invention thus preferably consists of a fiber-reinforced thermoset core and of a wear layer of plastic with or without fiber reinforcement. Due to the fiber reinforced thermoset material, the core is stiff but light at the same time. Thus, in particular the inventive shoe fitting is easy compared to conventional metal hoof fittings such as iron or aluminum. In contrast, the wear layer material is selected in particular because of its advantageous abrasion properties, in particular the abrasion should be low for a period of at least 4 or 5 weeks, at least so low that the wear layer in normal use (ie on the fogged hoof) at any point during this period rubbed off to the core. The polyurethane plastics proposed for this purpose are particularly suitable as wear-resistant wear layer.

Formation of cavities in the shoe fitting, in particular in the core, could further reduce the weight and favor the damping.

To protect the hoof, hoof fittings are usually attached tread-side with nails on the outer edge of the hoof part of a hoof. The hoof fittings protect and support the bottom side, in particular the edge of the hoof wall. Due to different functions of the horse's forelimbs and hind limbs, the hooves of the forequarters have a more circular shape and the hooves of the hindquarters have a more pointed shape. Horseshoes are therefore shaped differently accordingly. The shape can be largely referred to as U-shaped 3/4 ring, with the bottom side of a tread and hoofside a contact surface. Optionally, in the fitting on the bottom side (i.e., running surface side) in the middle a groove (fold) is created, where the holes for the nails are introduced. The grooves or the fold serve / serves as anti-slip.

Especially 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. As further advantages of the plastic according to the invention, as compared to known plastic fittings, which are particularly useful for racehorses, a lower sinking depth, a higher grip and reduced abrasion and wear are the advantages.

The special design for front and Hinterhuf described in the figures ensures an optimal grip, reduces the sinking depth and reduces dirt pickup, which also leads to energy savings.

The invention will be explained below with reference to examples.

EXAMPLES

Particularly good test results gave hoof fittings (similar to that of Test No. 5, Table 1) comprising a 2 mm thick core of carbon fiber, incorporated in thermosetting matrix, said core of fiber and matrix material with a wear layer of polyurethane, which advantageously reinforced with fibers of aramid. This ensures minimal abrasion. The lifespan is 5-6 weeks. The technical data of this particularly advantageous horseshoe are as follows:
