Definitions

  • the present invention consists of a horseshoe for horses. Specifically, the invention proposes a horseshoe for front limbs and a horseshoe for rear limbs whose structure helps to maintain the health of the horse, minimizes the time invested by the blacksmith in adapting and installing the horseshoe in the horse's hooves and provides a good finish or quality from the aesthetic point of view.
  • Horseshoes for horses are pieces that are stuck or stuck on the rims of horses' hooves. These are "U" shaped, that is, they are formed in a single piece from two branches, where each branch seen from its free end is separated into four sections called heel, fourths, shoulders and clamp.
  • Horseshoes are used to cover the animal's hooves to prevent damage and wear to these parts and to keep intact the natural movement of the animal in any task or Circumstance and mainly in competition activities, where the hardness of the tests and of the training subjects the structure of the legs to demands that test the integrity and functionality of the animal. Therefore, the horseshoe must be adapted to both the shape and size of the helmet, being large enough and long enough for it to have the necessary support. However, before being placed correctly, it is necessary to carry out an appropriate trimming and despalme to maintain the structure, the angle and the axis of the helmets as close as possible to the normal.
  • the horseshoe clamp comprises physical markers provided directly opposite each other both on the surface in contact with the helmet and on the surface in contact with the ground, wherein said physical markers function as a guide for cutting through the Horseshoe clamp.
  • EP 0899037 relates to a method for manufacturing horseshoes with clips or tabs, which attempts to overcome the disadvantages associated with the formation of unwanted thick edges.
  • a method is proposed in which during the manufacture of the horseshoe two transversely directed slits are provided, wherein at least part of the material located between said slits is pushed to form the flange.
  • this type of task is usually done by the blacksmith manually with a hammer and / or rasp and / or roughing machine. These tasks require that the blacksmith invest time, effort and money, costs that could be saved if it had a horseshoe that meets the needs and biomechanical needs of the animal and also provides a pleasing aesthetic to the eye ensuring quality from a Factory product.
  • the object of the present invention is to provide horseshoes with formats that resemble a greater number of anatomical varieties of the helmets, to reduce the time and effort required by the blacksmith for its correct adaptation to these, thus helping maintain the health of the horse and at the same time achieving a visually more harmonious work.
  • the present invention consists of a horseshoe for the forelimbs and a horseshoe for the hindlimbs of a horse, which are biomechanically more respectful with the animal member.
  • a unique horseshoe model with two formats that resemble the two anatomical conformations of helmets most commonly found in horses (Encastillada and Palmiplana) and from which, it is much easier to adapt them to all helmets.
  • the proposed horseshoe has as its first advantage that it has a suitable proportion between the width of the horseshoe and the size of the hull of the horse, being considered for the horseshoes of the previous members two different width measurements depending on the type of conformation of the case according to the anatomy of the member .
  • the horseshoe also has an improved ratio between the vertical support tab (clip) and the horseshoe itself, proposing different modalities that may include 1 and 2 clips or none, depending on the anatomy of the helmet or the function to be performed.
  • This benefits both the horse and the blacksmith since it provides a better fixation to the helmet according to the type of conformation (anterior limbs), which is fundamental both in normal hardware as well as with the use of studs or rivets.
  • the tab is large enough to continue to fulfill its function properly with a suitable contact surface so as not to break the helmet.
  • the perforations for the nails have been improved. First, they were placed so that they are correctly located on the white line of the horses' hooves. This is achieved by a correct proportion of the horseshoe material between the inner and outer hull area. Secondly, the perforations for the nails have a shape and angulation such that they provide a guide to achieve a good exit of the nail for its subsequent rivet. In this sense it is proposed for the two horseshoe formats for anterior limbs, piercing angles for nails (claveras) different between them to allow a placement of the nails more compatible with the angle of the helmet wall that resembles anatomically each type .
  • the horseshoe of the invention has beveled outer edges that progressively increase from the widest part of the horseshoe to the heels. This improvement advantageously decreases the chances of the horse removing the horseshoe when stepping on it with one of its other members or those of another horse and also the risk of a self-inflicted injury in case of hitting the horseshoe itself.
  • the proposed horseshoe On the face of contact with the ground, the proposed horseshoe comprises a lower slab at the outer edge of the clamp area between both shoulders, which also has a differentiated length for each format of previous members.
  • this bevel facilitates the start of the passage of the horse in the driving phase. It also helps reduce the hyperextension of both interphalangeal joints (distal and proximal), as well as reduces the tensions required in the deep flexor tendon.
  • the heels have also been beveled gradually to allow the sinking of these in the landing phase of the pass. With this improvement, the chances of injury are reduced in both the suspensory ligament and the superficial digital flexor tendon when sharing tensions with the deep digital flexor tendon.
  • no edge presents an angle of 90 °. All these edges are beveled, achieving a horseshoe more secure, economical in time and effort of the blacksmith, besides aesthetically harmonic.
  • a horseshoe has also been designed in which it is ensured that the width of the clamp and of the branches is constant to allow the inferior slab to work correctly and an even collapse of the horseshoe.
  • the angles of the inner side of the heels of the horseshoe do not interfere or damage the integrity of the area of the frog or padlock of the horse's hull. Also, consider their way to allow for easier cleaning.
  • Another feature of the present invention is that in the horseshoes of the rear members, two areas without perforating or grooving are provided in the shoulders to facilitate the drilling of holes for studs or studs.
  • This area as it does not have the material cast traditionally made, provides a better and safer fixation for the frequently used elements to improve traction and avoid skidding.
  • by preventing an excessive decrease in the material of the horseshoe it is possible to increase the resistance of the same and therefore prolong its useful life in the horse.
  • the horseshoe of the present invention has been advantageously designed in such a way that in its modality for hind limbs, it is asymmetrical in its branches, in other words, the dimensions and proportions of the left branch are different from those of the right branch with the object of fitting in a better way to the hull of the horse, thus respecting its anatomy, maximizing the effectiveness of the step and diminishing the injuries.
  • the proposed horseshoes that are described in more detail later, will advantageously have different "sizes” or "numbers" for different sizes of horse hulls, in which, only the thickness of the horseshoes and the rest of the horseshoes remain constant. dimensions vary proportionally among them being this an improvement to maintain the constant proportion between the different sizes of helmets and horseshoes.
