Elastic Patents (Class 168/28)
  • Patent number: 10463035
    Abstract: A hoof soling element to be attached under the hoof of an animal, in particular a horse, wherein said hoof soling element (1) is of uniformly increasing height which enables an area of the soling element (1) that is of lesser height to be attached under the front portion of the hoof and an area of greater height under the rear portion of the hoof, wherein said hoof soling element (1) is composed of a material having a Shore-A hardness ranging between 60 and 90. Said hoof soling is particularly suited for the treatment of laminitis and enables the load acting on the foot to be shifted to the healthy rear hoof portion, wherein as a result of the hardness of the material a sufficient amount of elasticity on the one hand and resistance on the other is achieved.

  • Patent number: 9179661
    Abstract: A horseshoe with a stabilizer-feature and splaying has a U shaped metallic unitary body with left-right wings and an integral compliant leaf-spring disposed proximate to or in the horseshoe toe area. The leaf-spring may be crescent-shaped or chord-shaped and resiliently deforms upwards, exerting sideways-pressure causing splaying of the left-right wings. The leaf-spring may have a groove on either side to assist preparation before horseshoe installation. The crescent-shaped leaf-spring forms a cavity with the hoof underside in use, which cavity is optionally filled with a resilient material, e.g., silicone, obviating accumulation of dirt/debris. Stabilizers comprising a plurality of rows of beads formed integrally with the horseshoe bottom form a negative camber on the horseshoe-underside. The stabilizer rows may be staggered and assist in the stability of the horse during racing, especially at track-curves. The horseshoe may be cast/forged, blanked, or welded and can be mass-produced.

    Abstract: The present invention relates to sole support pad for hoofed animals but more particularly to sole support pad for horses with laminitis or other foot problems. Said sole support pad comprises a curable resin-coating tiny expandable polystyrene balls which can be placed directly to the foot with or without shoes in a matter of seconds. It further relates to a process of producing said sole support pad comprising the steps of; coating polystyrene balls with poly-isocyanate prepolymer under dry atmosphere; allowing isocyanate and polyol to react; hardening the resin upon wetting with tertiary amine or organic peroxide solutions, and packaging coated balls in impervious package to prevent contact with atmospheric pressure.

    Abstract: An equine hoof appliance for horses, comprising a substantially flat pad having the general shape of the footprint of a horse's hoof and defining a curved toe portion and a substantially flat rear edge portion. The pad attaches to the ground-contacting surface of a horse's hoof and, on its opposite surface, mounts a horseshoe disposed around a ground contacting forwardly sloping and distally extending caudal projection on the pad. The caudal projection emulates and exaggerates the hoof frog and in so doing accomplishes two important objectives. The projection encourages heel first foot placement for maintenance of healthy phalanges alignment. Simultaneously the projection stimulates proprioceptive functions in the hoof to improve the horse's balance.

  • Patent number: 4565250
    Abstract: A horse shoe pad is formed of a shock absorbing layer and a stabilizing fabric layer. The shock absorbing layer may be made of a dense non-cellular polyurethane of essentially linear structure containing unsatisfied hydroxyl groups, having a compression set of less than 15%, and preferably less than 5%, an elongation at break of at least 500%, a recovery after compression which is delayed by about 0.7 seconds, and a hardness on the Shore 00 scale of approximately 70. The fabric reinforcing layer may be a woven nylon fabric. In addition to these two layers, some embodiments include an additional layer of stabilizing fabric on the opposite side of the shock absorbing layer and/or layers of polyester urethane forming base and/or top layers.

  • Patent number: 4557334
    Abstract: In order to prevent extraneous matter from adhering to hooves, expel any extraneous substances adhering thereto and assist the movement of the animal, a horseshoe-shaped insert body 1 is formed by a bent-over toughly elastic strip of material, the bend forming a tube 2 which contains an air chamber 5 of high resistance to counter-pressure immediately followed by air chamber 5' of low resistance to counter-pressure. The insert body has preliminary cuts 7 which, after being cut open, enable the width to be increased and also reduced. Closures 4 in the tube 2 separate the air chambers 5' of low resistance to counter-pressure which immediately follow them and of which the end parts 6 are open.

  • Patent number: 4513825
    Abstract: A horseshoe full pad to be interposed between a metal horseshoe and the hoof is made of an energy absorbing microcellular urethane foam having a tough outer skin. The pad is characterized by having a central layer or sheet which covers and can be trimmed to the hoof. Stabilizer bars and heel shock reducers are molded into the turf side of the pad and rise to about the level of the horseshoe so that they along with the shoe take up and absorb some of the shock. A frog pad may be molded into the hoof side of the pad to further protect and/or stimulate it.
