The invention relates to a closure assembly system for attaching a foot protection to a horn capsule of an animal by means of attachment means, which may be secured to a horn capsule wall of the horn capsule, and holding means, which are secured to the foot protection.
Equidae such as, for example, horses or donkeys and even-toed ungulates, so-called cloven-hoofed animals such as cattle or sheep, have hooves or claws formed of horn capsules at the lowermost part of the limbs. Just like claws and fingernails, they are worn out by use and therefore regrow constantly. Since such animals are today usually kept as domestic or farm animals, they are frequently no longer able to act out their natural movement behaviour, whereby growth and abrasion of hooves and claws often no longer match. In order to prevent diseases of the hooves or claws, they must be trimmed at regular intervals, depending on the strain, and, if need be, provided with a foot protection when the horn capsule is heavily stressed.
Especially with equidae, which are increasingly moved on hard ground, for example on tarred roads, the attachment of a foot protection is widely used. For horse, donkey and mule, a metal horseshoe is thereby nailed in most cases, which, however, might entail significant disadvantages for the body of the animal due to the lack of shock absorption and a rigid fixation of the movable tactile organ “hoof”. In addition, a hoof protection secured permanently for eight weeks by nailing has the disadvantage that the hoof horn, which regrows by two to four centimetres in the shoeing period, cannot rub off or be trimmed naturally so that the hoof increasing in circumference will remain fixed in its narrow initial position. This may lead to a faulty foot position and damage to bones, tendons and ligaments associated therewith.
Due to the shock-absorbing properties and the lower risk of injury, plastic shoes have increasingly been used in recent years, especially for horses used in leisure riding. A temporary nailless hoof protection permitting the natural movements of the hoof would be the ideal solution for preserving the animal's health. Solutions in the form of a shoe for hooves which can be strapped or glued on are already commercially available, with the disadvantage that, so far, they have had to be guided as far as over the fetlock joint, resulting in chafing and, due to the inaccurate adaptability, frequently in a loss of the hoof protection at faster gaits. The use of hoof shoes which are guided over the fetlock is not possible either in the sports sector, as they do not allow fast turning of the hooves on the ground at high speed.
A hoof shoe must be removed by the rider after the use of the animal, since the horse's leg sweats and rubs itself sore in the hoof shoe. For this reason, a hoof shoe should be limited exclusively to the attachment to the horn capsule and should be removable at any time on demand. In contrast, the hoof shoe should additionally be allowed to be left on the hoof for several days if necessary without running the risk of being lost or of chafe marks occurring.
Document DE 197 42 274 A1 discloses such a temporary hoof protection made of plastic, which is secured in the form of a hoof shoe to the horn capsule by means of a hook-and-loop fastener. A disadvantage of this hoof protection is the lack of adaptability to the hoof so that clearances between the hoof and the hoof protection occur, which is detrimental to the durability of the hoof protection on the hoof. Even if the hoof shoe is adapted precisely to the hoof shape of an individual animal, which would be very costly and expensive to buy and manufacture, the adaptation for this hoof protection is always only a snapshot, since the hoof grows and is thus in a permanent growth process. The document discloses a further hoof protection which is adaptable to the hoof of a horse to a certain degree. However, this hoof protection has turned out to be unreliable in practice.
The invention is based on the object of enabling a temporary foot protection for different hooves and claws, allowing a reliable connection between the foot protection and the horn capsule.
According to the invention, said object is achieved in that the foot protection has a sole plate and at least two adaption elements each having at least one leg and a base plate, wherein each leg is configured to be slidable essentially radially relative to the horn capsule wall by means of the base plate, which is configured to be slidable in a sole plate recess of the sole plate that is open towards the topside, and wherein each leg has one of the holding means, which are configured to be connectable with the attachment means in a sheer-resistant and detachable way.
In this way, the advantage is obtained that the foot protection can be adapted manually to a hoof or a claw quickly and easily as it is applied, whereby a shear-resistant and reliable connection between the foot protection and the horn capsule is formed immediately. Thereby, the connection between the attachment means and the horn capsule wall is configured to be stronger than the connection between the attachment means and the holding means. After use, the foot protection can be removed manually just as quickly and easily, while the attachment means may remain on the horn capsule.
Due to the reliable connection of the closure assembly system according to the invention, it becomes possible for the first time to attach a temporary foot protection precisely only to the horn capsule wall, preferably merely to a horn capsule side wall, of the hoof and to detach it therefrom. The adaption elements press the foot protection against the horn capsule so that advantageously a shear-resistant and detachable connection is rendered possible. In this connection, it is particularly advantageous that the attachment means for the horn capsule wall are attached to the horn capsule wall without damage. Thus, there is no penetration of a nail or a screw into the horn capsule wall, which would damage the horn capsule wall.
Advantageously, the holding means and/or the attachment means have a form-fit surface structure, preferably a surface structure according to 3M™ Dual Lock™, 3M™ DuoTec™ or VELCRO® Plastic Hooks. A form-fit connection between two such surfaces can be effected in a manually detachable way and, at the same time, has a particularly high shear strength.
Particularly advantageously, the holding means with such a surface structure are configured to be integral directly with a surface of the legs that is opposite to the attachment means. In this way, the manufacture of the adaption elements is simplified and the holding means need not be applied specifically to the legs.
The holding means and/or the attachment means can advantageously also be composed of a tape, preferably a one-sided adhesive tape having the form-fit surface structure. As a result, the holding means and/or the attachment means can be replaced easily and quickly.
Particularly advantageously, the surface structure is configured as a micro-structure. Due to their special surface properties, micro-structures enable novel actions and effects, for example, particularly stable connections or self-cleaning surfaces.
In a further advantageous embodiment of a closure assembly system according to the invention, the holding means and the attachment means are configured as an engagement connection, preferably as a snap-fastener closure or as a pressure cap brace or in the form of a press-lock or closure buckle. Those engagement connections have the advantage that the connection can be prestressed so that even in case of animals with difficult foot-to-ground behaviour (rotation of the hoof) the foot protection remains snugly on the hoof.
In a further advantageous embodiment of a closure assembly system according to the invention, the holding means and the attachment means are configured as a detachable cable tie closure, wherein preferably the attachment means are configured as a cable tie head and the holding means as a cable tie tab. This provides the advantage that the connection can be prestressed so that even in case of animals with difficult foot-to-ground behaviour (rotation of the hoof) the foot protection remains snugly on the hoof.
In a further advantageous embodiment of a closure assembly system according to the invention, the holding means and the attachment means are secured to the leg, wherein the attachment means have a suction cup structure or micro-structure facing the horn capsule wall and configured to form a sheer-resistant and detachable connection with the horn capsule wall, wherein the connection between attachment means and holding means is stronger than the connection between attachment means and horn capsule wall. In this way, the advantage is obtained that no attachment means must remain on the horn capsule. Particularly advantageously, the holding means and the attachment means are configured to be integral with a surface of the legs that is opposite to the horn capsule wall.
Suitably, the base plate of the adjustment members is insertable/displaceable into/in the sole plate in such a way that the position of the legs of the adjustment members is variable with respect to the sole plate. Thus, in connected holding means, a sole plate projection of the sole plate with respect to the leg of the adjustment member(s) is advantageously formed in the area of at least a portion of the following sections of the horn capsule wall: inner horn capsule side wall; outer horn capsule side wall; inner heel wall; outer heel wall. In this way, injuries caused by a possible supination (outward rotation/tilting) or pronation (inward rotation/tilting), i.e., “tilting over or buckling” of a limb of the animal, in particular of the horse, on the horn capsule 13, are advantageously prevented, and the foot protection according to the invention is also suitable for orthopaedic use, whereby malpositions can be corrected.
Particularly advantageously, the adjustment members each have a base plate, via which base plate they are connected to the foot protection, wherein the base plate is configured to be detachable from the foot protection. As a result, different adjustment members may, for example, be exchanged with different holding means which are compatible with the respective attachment means in a form-fitting and/or different way, for example, in a non-positive and/or firmly bonded way. Furthermore, adjustment members or holding means, respectively, which are broken or are to be cleaned can be removed and/or replaced easily.
Advantageously, the adjustment members and/or the foot protection are made at least in part from metal, in particular stainless lightweight steel, or aluminium, rubber, plastics, fibre-reinforced plastics or carbon, which provides the foot protection with the necessary stability. For example, the shock-absorbing properties can be improved by a plastic sole, and carbon has a particularly high strength at a relatively low density.
In an advantageous advanced embodiment of a closure assembly system according to the invention, the legs of the adjustment members are bendably connected with the foot protection or the base plate of the adjustment members via a joint or a living hinge. As a result, the adjustment members and the holding means can be adapted to the horn capsule wall.
In the following, the closure assembly system according to the invention is explained in further detail in a non-limiting manner on the basis of exemplary embodiments illustrated in the drawings.
In the following, reference is made to
The foot protection 1 has a sole plate 2. For reducing the dead weight, the sole plate 2 may have a recess 3. The sole plate 2 has an outsole 4 on its lower side facing away from the horn capsule in the applied state of the foot protection 1. The foot protection 1 has a toe protection 5 in its front area.
According to
In the present first embodiment, the sole plate 2 exhibits, in some areas, conical nubs on its side facing the horn capsule in the applied state of the foot protection 1, the nubs improving the adhesion of the foot protection 1 and the horn capsule in the applied state of the foot protection 1. For adjusting the flexibility of the foot protection 1 in the movable part of the heels of the hoof, a so-called “spacer” 19 in different degrees of hardness is insertable in the rear region of the sole plate 2. Thus, the flexibility of the foot protection 1 can be adapted individually to the needs of the animal.
The foot protection 1 comprises six adjustment members 9. Each adjustment member 9 has at least one leg 10 and a base plate 11. The leg 10 is connected to the base plate 11 via a living hinge 23. The living hinge 23 is formed of several weakening lines introduced into the material, thus allowing a flexible adjustment of the leg 10 relative to the horn capsule wall 14 as well as simplified pressing against and detaching from the horn capsule wall 14. Alternatively, the leg 10 and the base plate 11 may also be connected via a joint, whereby the leg would be rotatable about the hinge axis.
Via the base plate 11, each adjustment member 9 is connected to the sole plate 2. For that, the base plate 11 is configured to be slidable essentially radially relative to the horn capsule wall 14 of the horn capsule 13, whereby the legs 10 are adjustable relative to the horn capsule wall 14. The base plate 11 is thereby configured to be insertable into and withdrawable from a sole plate recess 17 of the sole plate 2 along an insertion direction ER running essentially radially to the horn capsule wall 14.
The base plate 11 and the sole plate 2 each have complementary surface structures 18, in particular sawtooth structures, which form a resistance against the insertion direction ER, on the surfaces which contact each other.
Each leg 10 comprises holding means 8. Those holding means 8 are integrated directly into a surface 20 of the leg 10. This surface 20 faces the horn capsule wall 14 in the applied state of the foot protection 1. Now, if attachment means 21 are secured to the horn capsule wall 14, the holding means 8 and the attachment means 21 are located opposite from each other and can be connected to each other in the applied state of the foot protection 1.
The adjustment members 9, which comprise the holding means 8 on the legs 10, and the attachment means 21, which can be secured to the horn capsule wall 14, thus form the closure assembly system 22 according to the invention for attaching the foot protection 1 to the horn capsule 13.
According to the first embodiment of the closure assembly system 22, the holding means 8 comprise a mushroom head-like surface structure according to
Because of this connection, it is possible to secure the attachment means 21 exclusively to the horn capsule side wall 15 rather than also to the heel wall 16 and the toe wall 12, which is beneficial for the animal and the user. Alternatively, the attachment means 21 may additionally or exclusively also be secured to the toe wall 12, the heel wall 16 and/or any other part of the horn capsule wall 14. The fixation of the attachment means 21 or the foot protection 1, respectively, can thus be adjusted according to the hoof shape of the animal, the application of the foot protection 1 or depending on the number and design of the adjustment members 9.
Due to the insertability or displaceability according to the invention of the base plate 11 into or, respectively, in the sole plate recess 17 of the sole plate 2, a sole plate projection 29 of the sole plate 2 with respect to the leg 10 of the inserted adjustment member(s) 9 can additionally be provided. This is shown in
The attachment means 21 may, for example, be configured as a one-sided adhesive tape which exhibits the form-fit surface structure on the side not comprising the adhesive. The adhesive tape is then glued to the horn capsule wall 14 or the horn capsule side wall 15, respectively, with the side comprising the adhesive.
Alternatively, the mushroom head-like surface structure of the holding means 8 and the attachment means 21 may also be configured as a micro-structure, e.g., in the form of a “gecko tape”. Furthermore, the surface structure of the holding means 8 and the attachment means 21 may be configured as hooks and loops or as “Metallic Velcro” made of spring steel.
A typical method of securing the foot protection 1 with the closure assembly system 22 according to the invention may be as follows: A foot protection 1 is chosen which is slightly larger than the hoof of the animal, for example having a diameter of about 13 centimetres. The foot protection 1 is then held against the horn capsule 13 and optionally reduced to the actual size of the hoof. In a following step, the hoof is cleaned with alcohol, and the attachment means 21 are secured, for example glued, to the horn capsule wall 14. Then, the foot protection 1 is held against the horn capsule 13, and the adjustment members 9 are pushed manually toward the horn capsule wall 14. Once the holding means 8 are accurately aligned relative to the attachment means 21 to a sufficient degree, the mushroom head-like surface structure of the holding means 8 is pressed manually or by means of a plastic roller into the mushroom head-like surface structure of the attachment means 21, and the sheer-resistant connection is thus produced. After use, the foot protection 1 can easily be removed from the hoof manually, whereby the holding means 8 are withdrawn from the attachment means 21.
Alternatively, the cable tie tab may also form the attachment means 25 glued, for example, to the horn capsule wall 14. The adjustment members 9 may exhibit a cable tie head which is integrated into the leg 10 and through which the cable tie tab is pulled.
Alternatively, the attachment means 27 and the holding means 26 may also be firmly glued together or even formed in one piece, since the hoof protection 1 is, again in this case, configured to be connectable in a detachable way, and, hence, the technical effect of the invention is not impaired. Alternatively, the attachment means 27 have a micro-structure, for example, a gecko structure, which faces the horn capsule wall 14 and is configured to form a sheer-resistant and detachable connection with the horn capsule wall 14.
Advantageously, the sole plate 2 is made of a particularly resistant, hard material of low density, for example aluminium, plastics such as, e.g., polyethylene (PE) or polypropylene (PP), particularly advantageously of a particularly resistant, hard material of particularly low density, for example carbon.
Advantageously, the outsole 4 is made of a resistant material with good shock-absorbing properties, for example plastics such as, e.g., ethylene vinyl acetate (EVA), or rubber.
Advantageously, the toe protection 5 can be used for safety purposes, for example using an attached light-reflecting passive reflector element, for information purposes, for example using an attached name of the animal or a code number, or for marketing purposes, for example using an attached emblem.
Advantageously, the holding means 8 can, in addition, also be connected positively to the attachment means 21 by applying an additional force acting essentially radially on the horn capsule wall 14. An additional screw connection may, for example, serve for this purpose.
In all embodiments of the invention, the attachment means for the horn capsule wall can be attached to the horn capsule wall without damage. Thus, there is no penetration of a nail or a screw into the horn capsule wall, which would damage the horn capsule wall. This improves the durability and health of the animals with regard to their hooves or claws.
