Definitions

  • the present invention relates to a hoof protection for equines (e.g. horses, donkeys) as a combination product, comprising at least one hoof protection sole and a hoof protection strap system, for attachment to a hoof of the equine in particular for therapeutic purposes, and the method for its attachment without the need for nailing on Huf, as well as the method for producing the combination product by means of thermoplastic primary molding processes, in particular by means of injection molding processes.
  • equines e.g. horses, donkeys
  • Equidae especially horses, have been used for thousands of years as farm animals for pulling or carrying loads or for (their own) locomotion.
  • the applications of the invention described below relate not only to horses, but also to other equidae (e.g. donkeys), which are also meant herein.
  • the equidae are mammals of the order of the odd-toed ungulates, which represent the family of the horses, especially the horses as solipeds.
  • An equine and/or equine hoof is used as a synonym for the anatomical designation of the hoof capsule.
  • the hoof capsule of the equine consists of the hoof wall, which encloses the hoof laterally, the hard hoof sole, which ends at the ground and the hoof frog, the soft part of the hoof sole.
  • the bottom edge of the hoof wall, the so-called bearing edge, and the hoof sole are separated by the white horn line, which shows the farrier, for example, where nails can be hammered in without damaging the sensitive dermis.
  • the upper edge of the hoof capsule is called the hoof crown, which merges into the normal hairy skin.
  • the hoof capsule is divided into three areas from front to back. The front area is called the toe, the middle right and left is called the side wall and the rear area is called the heel.
  • hooves of domesticated horses on the other hand, which are used more frequently or more unilaterally for economic or leisure purposes than horses living in the wild, must be regularly protected.
  • Hoof protection hereinafter encompassing the various embodiments of horseshoes, hoof shoes, hoof protectors and hoof protection devices, is typically a necessity in the hoof care of domesticated horses.
  • the attachment of a hoof protector by the user has a direct influence on the gait mechanics and thus on the mobility of horses.
  • Optimal hoof protection is therefore of crucial importance in the entire equestrian sport sector, such as equestrian sports or vaulting.
  • An important tool is the optimal hoof protection in the therapy or rehabilitation of horses, especially in high-performance equestrian sports (e.g. show jumping, dressage, military, polo, horse racing). Hoof protection that can be worn 24 hours a day for a few weeks or months has proven to be particularly effective for therapeutic purposes and has developed into a high-selling product niche in its own right.
  • the demand for optimal hoof protection is not limited to therapy; veterinarians, horse breeders, blacksmiths and farriers are equally dependent on the development of commercially available hoof protection.
  • the demands on optimal hoof protection are as diverse as the horse's possible uses.
  • the high specific weight of a metal hoof protection is disadvantageous for the movement and can pose an increased risk of injury for the horse, its peers and humans. Due to its weight, the horseshoe is subject to high centrifugal forces during the horse's gait, especially at higher running speeds such as the trot or especially when cantering, which can irreversibly damage the horse's musculoskeletal system. Furthermore, the shock-absorbing effect of the hoof is significantly reduced by the metal shoe, so that the high-frequency impulses, which can be heard as the characteristic clicking sound of the horseshoe, can lead to physiological damage in the anatomical structure of the horse's musculoskeletal system, which is detrimental to the entire gait mechanism affects. In order to counteract a direct power transmission caused by the hardness of the metal, however, two-component systems such as damping plastic elements between the horseshoe as hoof protection and the hoof of a horse have not been able to establish themselves.
  • Plastic hoof protectors have been commercially available for several years and can be selected from a large number of plastic groups and their composites according to their diverse properties and depending on the requirements (e.g. subsoil, weather).
  • the profile of requirements for hoof protection is very complex and consists primarily of the requirements of the gait mechanics (constantly changing loading and unloading due to the weight of the animal, impact and abrasive processes), the changing soil conditions (meadow, sand, gravel, stones, pavement). , asphalt), the changing weather conditions (e.g. temperature fluctuations) and the chemical conditions (corrosion caused by faeces or damp stable flooring).
  • plastic plates are either too heavy for safe and long-term attachment or that the material of the hoof protection is not robust enough to meet the requirements of optimal hoof protection.
  • Plastics that meet these material requirements are often not sufficiently workable (cutting, flexing or sawing) after the production of the molded parts in order to achieve an individual fit for the hoof.
  • polymeric plastic materials for the use of a hoof protection which allow a mechanical post-processing, are usually too soft or so temperature-sensitive that a thermal post-treatment leads to an uncontrolled deformation (e.g. bulging).
  • a progressive deformation of a polymer hoof protection with the wearing time is already known due to the unidirectional and frequent force effect of the loading and unloading processes according to the movement mechanics of the horse, especially in heavy horses. Subsequent deformations of the hoof protection must be avoided in any case, as they can lead to pressure points or orthopedic damage to the horse.
  • Special additives such as plasticizers or fillers can be used to modify the mechanochemical properties of plastics to a limited extent, for example to improve traction, especially grip on a solid surface.
  • an integrated hoof protector divests the desire to combine the beneficial properties of metal and plastic for the hoof protector.
  • the integrated hoof protection designates a combination product from metal segments embedded in polymer.
  • products with a metal or carbon core embedded in plastic are known.
  • the use of different materials within the hoof protection is usually disadvantageous.
  • the hereinafter referred to as multi-component The situation described as a problem describes this intrinsic disadvantage of the incompatibility of individual components with regard to different claims. If several materials, in particular with different physicochemical properties, are used together in the same shaped body, the stability-related suitability of the shaped body consisting of several components is limited, for example.
  • the coefficient of thermal expansion is a substance-specific material constant that describes the changes in the dimensions of a molded body when the temperature changes and serves as a measure of the heat resistance.
  • Horse shoes designate a non-permanent hoof protection which, in contrast to the aforementioned hoof protection variants, is generally pulled over the hoof of a horse.
  • horse shoes made of plastic are commercially available in different sizes and/or standardized dimensions, an individualized adaptation of the hoof shoe is only possible to a limited extent.
  • the use of the hoof boot is limited to horses with hoof sizes close to standard measurements.
  • moisture or foreign bodies e.g. small stones
  • dirt can build up in the horse shoe, resulting in wet chafing and microbial Favored infestation to the point of rot.
  • Patent specification DE102006006880B4 discloses a hoof shoe (comprising a sole and a detachably connected shell-like upper with lateral boundary walls), the closed design of the sole enabling the gait to be supported over the entire hoof contact surface by a single elastic plastic material and thus a solution for the multi-component problem shows.
  • Patent specification DE202012101920U1 describes an orthopedic hoof protection made from a solid material made from thermoplastic polyurethane (TPU).
  • TPU thermoplastic polyurethane
  • the disadvantage here is that the base plate of a hoof protection is made from a cross-linked TPU, which severely restricts the flexibility of the sole.
  • hoof shoes, hoof protection or fittings made of iron or aluminum and their alloys as well as plastic or its composites have established themselves as unsatisfactory to date.
  • Metals show insurmountable disadvantages of high weight or lack of slip resistance.
  • Multi-component systems have not been able to establish themselves satisfactorily by gaining the advantageous properties of several materials, since the incompatibility of the individual components results in the disadvantage mentioned.
  • the most promising approach to optimal hoof protection is the use of synthetics.
  • Plastic hoof protectors are generally attached to the hoof with either nails or adhesives. Fixing the hoof protection with nails is invasive; it damages the horse's horn material, making the horn material unstable and susceptible to microbial colonization and/or putrefaction.
  • US1761241A describes the attachment of a hoof protector to a hoof by a plurality of inwardly oriented teeth and tines by means of three releasably attached L-shaped fingers, the attachment being similarly disadvantageous due to the number of parts and the time consuming attachment and removal of the hoof protector to the hoof.
  • Patent specification DE10346480A1 disclosed a product for releasably attaching a multi-part hoof protection by means of a hanger which adheres to the hoof and which is attached to the hoof protection unit with at least one traction means and is designed to remain on the hoof.
  • the disadvantage here is a short wearing time, due to the complex fastening structure using clamps, tensionable traction means and buckles.
  • DE 102016 110657 A1 includes a hoof protection whose base plate is fixed to a hoof by means of a Velcro fastener. This step solves the need for partial and time-consuming hoof protection application and the multi-component problem, but hook and loop fasteners are not beneficial for long-term therapeutic applications, nor in the dirty and microbial-laden environment of equine housing.
  • hoof protectors that are attached to the outside of the hoof with at least one attachment strap.
  • Tab systems made of tear-resistant elastomer are generally attached to the horse's hoof by bonding to a variety of plastic hardware by bonding the surface of the tab to the surface of the hoof wall.
  • Adhesives such as one-component adhesive kits, are used to bond tab systems with plastic fittings.
  • the adhesive attachment is not satisfactory for the long-term use of attaching a hoof protector to a horse's hoof because it is not very secure or reliable.
  • even the strongest adhesive bonds cannot permanently withstand the permanent mechanical and chemical demands of a hoof protection.

  • the nature of the monomers, the number of repeating units and the way they are linked determine the physicochemical properties of plastics to a large extent.
  • An effective modification of the properties of a plastic without changing its basic chemical building blocks and/or altering the composition of the monomers is technically very important and is possible through chemical crosslinking of the macromolecules. In this way, technically relevant parameters can be modified in an economically advantageous manner without a large number of different monomers being necessary as basic chemicals.
  • Crosslinking in the sense of an intermolecular ligation of mostly linear macromolecules, leads to a multiplication of the molecular weight of the polymers.
  • thermo-elastic properties of the crosslinked products with increasing crosslinking is relevant in terms of material technology, until the individual polymers are connected to form a common covalent network.

Abstract

La présente invention concerne une protection de sabot stable dans la durée à monter sur des équidés (par ex., chevaux, ânes)) se présentant sous forme de produit combiné, ladite protection de sabot comprend au moins une semelle de protection de sabot et un système de pattes de protection de sabot, à monter sur un sabot, en particulier à des fins thérapeutiques. La semelle de protection de sabot selon l'invention, destinée à un sabot d'équidé, comprend au moins une plaque de base constituée d'un polymère thermoplastique (TP), le TP présentant une dureté d'au moins 35 Shore (A) et la plaque de base présentant une face supérieure et une face inférieure, et la face inférieure de la plaque de base reproduisant sensiblement la forme de la surface de contact avec le sol du sabot, ce qui permet d'obtenir une protection de sabot qui est légère, résistante aux sollicitations chimiques et mécaniques, amortit les chocs et est adaptée par conséquent aux forces impulsionnelles des allures du cheval. Le procédé selon l'invention apporte une solution au montage de la protection de sabot et permet un montage et/ou remplacement rapide, simple et non invasif de la protection de sabot, sans nécessité de la clouer au sabot, l'invention comprenant un procédé économique de fabrication du produit combiné au moyen de procédés de préformage thermoplastiques, en particulier au moyen d'un procédé de moulage par injection.
