FIELD OF THE INVENTION

The field of the invention is horse shoes.

GENERAL PRIOR ART

For centuries, horses have misted up as the most popular solution for protecting their hooves from humans. But horseshoes are a very bad solution. Not only can a horseshoe hinder the natural growth of the hoof, but it can also limit the hoof's natural ability to expand and adapt during exercise. This can reduce the ability of the hoof to cushion impacts, which can result in injuries to the delicate soft tissue and joints of the hoof and lower leg. The hindrance of a horseshoe can cause a shortening of the hoof, which can lead to heel pain, severe lameness, and even loss of use. Other negative effects include lack of jet pressure and natural hoof support necessary for proper blood circulation.

In recent years, many horse owners prefer the more natural approach of having their horses go barefoot. Unfortunately, this can also hurt the hooves. Wild horses can well maintain their hooves by keeping them moving, but domestic horses tend to need additional protection for their hooves. Among other things, they are not able to harden their hooves within the limits of domestication and are often exposed to dangerous and unnatural soil conditions when riding.

One solution is to let the horse wear hoof boots. Two examples in the patent literature are discussed in U.S. Patent No. 5,661,958 (to Glase) and U.S. Design Patent No. D440,363 to Ford.

Unfortunately, the known hoof boots tend to be poorly adapted to various hooves, and tend to fall off the hoof during extreme movements. For example, in the design patents '958 and' 363, the shoes hold the heel in place by grasping the lowermost portion of the heel with a belt and using gripper teeth to grasp the hoof wall. The gripping and grasping, especially by the gripper teeth, can cause considerable damage to the hoof wall. Also, this holding method works only with horses that are fogged, or with barefoot horses, where the hooves are padded or glued. There is another problem in that the strength of the shoe and its closed design tend to pinch foreign matter between the shoe and the hoof during use. As soon as dirt and mud reach the hoof, they can cause painful bruises on the sole of the hoof. Therefore, shoes must be properly adjusted according to the '958 or' 363 patents and regularly inspected for foreign bodies.

US Patent Application Nos. 2004/0168813 (Ford), 2005/0150197 (Ford) and 2005/0166556 (Ford) describe improved hoof boots which can be worn like sneakers. Unfortunately, such shoes provide insufficient clearance on the shackles. An additional problem is that the belt tensioning mechanism directly loads the coronary band (junction from the horn to the soft tissue), which can damage the newly grown, fresh hoof horn or the delicate coronary band itself. Still further, the '197 and' 556 designs have not solved the problem of the incoming foreign objects which, as mentioned above, can damage the hooves.

Ford tried to solve the problem of foreign objects entering by using a "gaiter", see publication 2005/0066632. But in actual use, such leggings can even pick up foreign bodies and exacerbate the problem.

U.S. Patent No. 4,744,422 (Dallmer) provides a hoof shoe with mountable straps. Although the straps of this design are less stiff than a closed shoe, they still do not provide adequate flexibility and adequate support for the hoof. Furthermore, the '422 design has insufficient clearance for the dislocated tether bones and is open on the underside, thereby providing little protection for the sole of the hoof.

GB 2 128 867 A discloses a horse shoe assembly adapted to receive a hoof and comprise a body of elastomeric material. The horse shoe is open at the back and picks up the hoof through a rear opening. Further, the horse shoe includes soles to which a strap can be attached to close the horse shoe at the rear opening.

Consequently, there is a need for a hoof shoe that provides better fit, better grip of the hoof, and reduces entrapment of debris. BRIEF SUMMARY OF THE INVENTION

The present invention provides an apparatus, systems and methods in which a hoofshoe comprises a base, a heel-holding portion ("heel-holder") and a mechanism that movably couples the heel-holder to the base.

The base and the other components of the shoe may be made of any suitable substance or substances. At present, polymers are preferred, with the heel holder formed as a mesh with multiple openings. A liner under the heel cup can be used to provide extra protection. The sole of the shoe preferably has a maximum height of 9 cm from the top of the sole.

The heel-holding member may be coupled to the base in any suitable manner. Preferred coupling mechanisms provide sufficient clearance to provide free-standing heel hold up / down and fore / aft displacement of at least 1.2 cm. A particularly preferred coupling mechanism is a mechanically favored belt system with Velcro fasteners. The belt preferably extends through a channel and the pivoting mechanism has a boundary point at which the belt leaves the channel. Such mechanisms are particularly advantageous in that they allow the heel holder at least three degrees of freedom of movement relative to the lower part.

The lower part of the shoe may comprise a sole with a top, and the pivoting mechanism is preferably arranged at a boundary point within 2 cm from the top of the sole. In many cases, the boundary point is also located at least 4-6 cm to the rear from the front of the base. In other aspects, the base may have a front side and a rear side, and the pivot mechanism may have a boundary point that is rearwardly located at least 50% of the distance between the front side and the back side. In still other aspects, the pivot mechanism (which could be a pivot pin) may advantageously have a rotatable or other boundary point within 2 or 3 cm from the back of the base. By advancing the pivot pin in the direction of the cable guides, the action of the heel holder rotated by the pivot pin is improved in a manner more consistent with the non-rotatable version. As an extreme example, if the pivot pin were in perfect back alignment, the action of the heel cup would be identical to the non-pivotal version in terms of its ability to move with the foot. In this context, there is a "sweet spot", which achieves a balance between movement, restriction and support.

Clamping mechanisms are preferably mechanically favored to some extent, and may also include a locking device. A tongue may advantageously be under the tensioning mechanism.

Various objects, features, aspects and advantages of the present invention will become more apparent from the following detailed description of preferred embodiments of the invention, taken in conjunction with the accompanying drawings, which are generally drawn to scale and in which like numerals represent like components.

DETAILED DESCRIPTION

In FIG. 1, a hoof shoe 10 generally comprises a base 20, a heel holder 30, a tether 40, a hook tape 50 with ropes 60, and a liner 70.

As shown in FIGS. 2 and 3, a heel holder 30 may comprise a single contoured portion having a domed top surface 106, a strap holding portion 104 extending from a bale 105 on each side of the heel cup 30, an attachment position 101 on each side, which also extends from the bale 105, and an edge 108. The belt holding portions 104 and the fixing positions 101 extend from a bale 105 on each side of the heel holder 30.

The domed top 106 extends from one of the belt retaining portions 104 to the other, as seen in FIGS. 2 and 3. Preferably, the domed top 106 has a U-shape or other fit that provides adequate clearance for the anklebone area of the hoof, as shown in FIG. As explained above, when the horse is carrying a weight, the tether bones are very low and may approach at angles parallel to the ground or at lower angles near or below the ground surface, especially at higher or faster gaits such as fast trot, canter or gallop , The arched top surface 106 is advantageously adapted to the contours of the soft tissue of the tether bones to allow ample bones ample headroom for alopecia without compromising the bones and tendons, or to abrade the soft tissue and lateral cartilages of the lower leg. Another advantage of the domed design of the top 106 in Figure 4 is that it provides adequate closure and support of the heel of the hoof within the shoe.

Extending from the domed top 106 to the rim 108, the heel holder has two bale sections 105, one on each side. In preferred embodiments, the bale sections 105 have a concave-arched design that conforms to the contours of the horse's hoof. Of course, hoof boots may require different contours for animals other than horses, and all of these contours have been provided since the present inventive subject matter provides applications for other ungulates including, in particular, mules and other equine animals.

In contrast to the toe area of a hoof, the heel area comprises sensitive soft tissue, tendons, cartilage structures that surround most of the heel and lower leg. The customization of the hoof shoe in the heel area is important to reduce pressure points on the soft tissue, tendons and lateral cartilages and will minimize the potential for hematopoiesis, chafing and abrasion of the hoof capsule. By conforming to the contour of the bale, the bale sections 105 can advantageously provide customizable flexibility and comfort to the heel and hold the heel in the shoe and withstand tremendous forces acting on the heel inside the shoe.

A belt holding portion 104 is located on both sides of the heel holder 30. The design of the heel holder is an open mesh architecture. Preferably, instead of a closed continuous part, the heel holder 30 comprises a part with different sized holes 107. It is provided that the holes 107 have an oval shape and average 1.5 cm x 1.0 cm in size. Other shapes such as rectangular, triangular or any irregular shapes are also provided. Likewise, the size of the holes may vary from small 0.1 cm diameter circles to 5 cm diameter circles. The belt holding portions 104 are essentially two large holes that can receive a holding belt 30. They look like the heel of the heel. The advantage of open mesh design is that dirt and debris can escape from the hoof. Enclosing or wrapping the hoof with a closed shoe may, in use, pinch foreign matter such as sand, stones, dirt, gravel, water, mud, and snow between the shoe and the hoof. If debris remains there for any length of time, it can cause damage ranging from bruising to chafing to abrasion. This is especially problematic on the heel part of the hoof because there is quite a soft tissue in this area. Therefore, the open mesh design allows debris to fall out of the shoe rather than being trapped.

As shown in Figures 4 and 5, the edge 108 of the heel holder is a straight edge, which adapts to the contours of the body of the heel holder 30. In preferred embodiments, the rim 108 is open and separated from the underside 22 of the base 20 of the heel cup 30. The open nature of this connection between the heel holder and the lower part also allows the ejection of foreign bodies. Those skilled in the art will understand that there is no attachment to the rearmost portion of the shoe. The lack of attachment in the back of the shoe allows the heel holder to follow the hoof and snugly and snugly conform to the hoof, minimizing puncture pressure. This not only serves to reduce the formation of bruising and chafing, but also to maximize the holding and holding capacity of the heel holder. As shown in FIG. 5, the hoof (not shown) in the shoe 10 may be pulled up, out, and down out of the shoe without having to apply uneven or punctate pressure to the heel cup 30 since it is connected to the caudal portion the hoof cooperates and tries to hold on to it.

In an alternative embodiment shown in FIGS. 6 and 7, the heel holder 30 is fastened to the underside 22 of the lower part 20 via a hinge 110. The hinge 110 sits in the central region of the rim 108 and is connected to an edge of the underside 22 by inserting a steel rod (not shown). The hinge 110 is then pressed into the bottom 22 and the steel rod passes through both the bottom 22 and the hinge 110 to form a secure connection. The action of the joint allows flexibility of the heel-holder and allows the top of the shoe to open wide, which makes putting on and removing the shoe much easier. In extreme conditions, such as trotting through heavy mud, deep snow, or other rough terrain, when the hooves need more grip, horses can wear hoof boots with a heel-to-toe joint. For example, in deep mud, the vacuum or suction of the mud causes an extreme force on the shoe, resulting in undesirable movement of the shoe in its normal relationship with the hoof. With prior art shoes, such forces can easily cause the shoe to partially or completely slip off the hoof.

However, where the heel holder is pivotally connected to the lower part of the shoe, the hoof must remain in the shoe. Even if the horse tries to free itself of the shoe, or for some other reason there is an extreme unpredictable movement of the horse or obstruction by the opposite hooves, the heel holder with the joint can move freely along the hoof.

Both in the embodiments of the present invention and in those without a joint, the action of the shoe can automatically adapt and the shoe bottom can automatically tighten, thereby increasing the holding and holding force of the heel holder and making it almost impossible that the shoe unintentionally releases the hoof.

In another alternative embodiment (see Figure 17), the version of the shoe with the joint is combined with a complete tethered heel liner and a tether strap or ankle strap to provide even better foot and / or shoe support. This variant is particularly good at holding the foot when the interior of the shoe becomes slippery, as in the case of use in deep mud or deep snow. By using the joint and a hamstring, the heel inside the heel cup is even more limited than in a variant without a joint.

A liner within the articulating shoe may further prevent abrasion of the hoof when the hoof moves relative to the heel holder, in the same manner a sock may assist in preventing a person's heel from rubbing against the back heel to protect a shoe.

It will be understood that heel retainers, as discussed herein, may be designed to automatically conform to the heel height of the hoof, which may vary from animal to animal. Furthermore, heel retainers may be shaped to provide close contact with the connected and bulbous contours of the rear hoof area. Still further, heel retainers may be made of sufficiently flexible, flexible and conformable materials to maximize close contact and reduce the potential for punctiform pressure that may be caused by variations in the contours of various hooves. Presently preferred embodiments include an integral fitting of urethane, rubber or other elastomeric material, or a single material or composite of materials such as urethane, leather, rubber, vinyl, plastic, a flexible one

Plastic plate, a sponge neoprene plate, heavy fabrics or canvas, various cords, straps and / or other textile materials. All of these minimize or at least reduce the possibility of wound chafing and bruising.

In Figure 8B, there are mounting positions 101 on both sides of the heel holder 30. In adaptation to the open design, the mounting positions 101 are preferably of circular shape and have on the side 102 of the heel holder 30 has a slot 103 through which introduced a pulley becomes. This allows ropes 60 to pass through slot 103.

In FIGS. 13 and 14, the lower part 20 of the shoe has two sides 304, a front flap 302 and a bottom 22.

The sides 304 are conformed to the shape of the hoof and extend from the back of the shoe and continue in a curved shape on both edges of the shoe to form a sloped and round shape. On each outer surface of the rim there is a cable guide 62. The cable guides 62 are projecting portions that include at least one hole on one side and two holes on the other side to allow the cables 60 to move from the front to the heel holder extend.

In preferred embodiments, the front flap 302 extends from the underside 22 and covers the sides 304. To prevent damage to the soft tissue, the front flap 302 takes into account the structure of the hooves. It is envisaged that the front flap 302 will not cover the top portion of the hoof wall. More preferably, the front flap 302 sits below the toe. This lower version prevents foreign bodies from reaching the sensitive soft tissue. The prior art ends at or near the soft tissue at the toe where the hard hoof wall horn is not fully developed. Having a higher front area will damage the hoof. Old shoe outer skin may rise over the toe, allowing foreign bodies to enter the soft tissue, which may cause bruising, abrasion, and abrasion, especially if foreign matter is trapped between the hoof and the shoe.

In a preferred embodiment, the front flap 302 acts like a tongue, which is enclosed with protruding sides. It is envisaged that the front flap is a maximum of 10 cm and preferably 9 cm high. The lower version of the front flap allows deviations in the hoof angle, which allows the shoe to adapt well to the hoof wall. Hoof angle varies from hoof to hoof and from horse to horse. The thickness of the front flap is preferably not more than 1 cm. The minimum thickness is desirable in the toe area as it reduces the possibility of damage to the horse's hoof. The protruding features of the front flap 302 on the sides form a strong closure which serves to protect against foreign objects. This protruding front flap is in contrast to the prior art, which includes a V-joint between the adjustable portion and the front portion or a fork-shaped folding tab that is generally loose and does not close well.

The lower part of the shoe can be made of any suitable material. Preferred embodiments include a flexible, hard, resilient and elastic material that allows for normal expansion and contraction of the hoof while allowing blood to circulate the hoof and cushioning impacts. It is envisaged that the material of the lower part should not hinder the natural movements of the hoof, z. B. a lateral vertical displacement when the hoof comes into contact with different terrain. It is important to avoid overloading bones, joints, ligaments, tendons and other connective tissues in the horse's foot and lower legs. It is also envisaged that the base can have a variety of colors and owners can decorate the base with different features such as glitter and rhinestones.

Presently preferred embodiments comprise a one-piece molding of a polymeric substance or an elastomer material having a Shore D hardness of 40. It is envisaged that other materials are possible. Materials such as urethane, rubber or other elastomeric material or a single material or composite of materials such as urethane, leather, rubber, vinyl, plastic, a flexible plastic plate, a sponge neoprene plate, heavy fabrics or canvas, various cords, straps and / or other textile Materials can be used.

The sole 500, as shown in Figure 18, is a shape similar to that of the barefoot of the horse. In preferred embodiments, the sole 500 has a protruding outer edge 502 and a jet pressure zone 504 that tapers from the sole towards the center of the shoe. Jet pressure is particularly important for maintaining the correct hoof extension and contraction during loading and unloading. The shape allows the shoe to maintain the natural ground pressure and traction capabilities of the barefoot while wearing the shoe.

In preferred embodiments, the heel holder 30 is attached to the lower part at fastening positions 101, which are shown in a rotational movement in FIGS. 1, 2, 4, 5, 9, 11 and 12. The rotational movement involves the use of loose pivot points that have more than one degree of freedom of rotation and allow the heel holder to move in all directions. In FIGS. 11 and 19, pulley block 122 includes two end pieces 128 and a connecting piece 129 about which the rope is arranged. As shown in Figures 8B and 11, the cables 60 pass through the cable guide 220 to the front of the base 20 and allow the heel holder to have elasticity when worn. Preferably, the cables 60 extend through the cable guides 220 to the front of the base and change to the opposite side. The mechanically favored cable belt reduces the clamping forces required by the cable tensioning mechanism due to the continuous cables running around the cable pulley. The use of a mechanically-biased web also serves to reduce the effort required by the user in tensioning the belt system, thereby eliminating the need for splined or similar systems.

The pulley block 122 is preferably designed flush with the general contour of the heel holder. The pulley block 122 may be made of any suitable material, including plastics. Other attachment types and modes may be used alternatively or additionally.

Preferably, the ropes 60 are made of stainless steel, but other types of resilient, flexible and durable ropes are provided. In preferred embodiments, the diameters of the cables are no greater than 1 cm.

The rope tensioning mechanism, also known as the coupling system, provides free-standing heel-holder up / down and fore / aft displacement of at least 0.5 cm, preferably 1.0 cm, and most preferably 1.2 cm.

In a particularly preferred embodiment, the rope from the rope tensioning mechanism arrives at or near the top portion of the tongue, traverses rearwardly the lateral rope guides around the pulley block located at the forward distal ends of the heel holder, then forward through the lateral rope guide and continue on the cable guide, switch to the opposite side and the same applies to the other side. This web serves to reduce the tension forces required by the cable tensioning mechanism due to the rope passing through and around the pulley block. The use of the roller system to increase the mechanical advantage is well understood and its use here is to reduce the effort required by the end user to tighten and secure the cables, whether the shoe is now with a rope lock reel / reel or a Velcro strap or other means for Clamping and securing the ropes is used. The use of a mechanically-biased chuck system is also advantageous because it alleviates unfavorable disengagement that would tend to occur in a direct chuck system.

Figure 4 illustrates the perspective view of the rope tensioning mechanism in action. It shows how the heel holder can freely rotate in extreme motion along the hoof by allowing the heel holder to hold not only the hoof in the shoe but also enough Movement to the side and up and down allows, so that the hoof can move freely. The cables increase in tension as the hoof moves upwards, which in turn increases the holding pressure of the heel and further reduces the possibility of the hoof inadvertently loosening from the shoe during use.

The heel holder 30 may be attached to a shoe base by any suitable means, including, for example: adjustable ropes, cords, straps or other similar structures. Preferred heel retainers only emerge from the front lateral distal ends of the heel holder and then rotate on the lateral region of the shoe bottom without other direct attachments thereto. This method of attachment allows the heel cup to move freely along the hoof as the hoof moves in use relative to the shoe, allowing the heel cup to retain maximum and closest contact with the hoof, allowing for maximum effectiveness in the shoe to keep the hoof.

As shown in Figure 5, a preferred heel cup may be loose and freely movable, flexible and upwardly adjustable, allowing the heel cup to conform to different heel heights of the hoof which vary from hoof to hoof and from animal to animal can. This is in contrast to prior art designs where the heel cup is attached to the rearmost portion of the shoe, requiring constant adjustment of the shoe. Many fittings are also required to find the appropriate size for the hooves. It is envisaged that heel retainers could be designed such that they do not require any adjustments or fittings and instead automatically adapt to different heel heights as they are pulled over the hoof. Additional benefit in addition to this automatic adaptability is the fact that a hoof may vary in height from day to day, week to week, and month to month, making shoes, adjustments, or parts replacement in use impractical would have to deal with heel height adjustment to accommodate the potentially frequent variability of any hoof.

At the front of the shoe lower part, a belt and loop fastener is used to receive the cable tensioning mechanism. Figures 8A and 9 show a hook strap 50 on the base 20 with a buckle adapter 202 on each side.

In preferred embodiments, the hook strap 50 is a continuous material 206 that folds in two plies, as shown in FIGS. 10 and 11. The hook strap initially loops around the buckle adapter 202 on both sides for a secure connection, then the hook strap passes through the outer portion of the buckle adapter and buckles the bottom layer. The inside of the layers comprises an adhesive material, preferably a hook and loop fastener or other velcro material, which allows the two layers to close each other and form a strong bond. This mechanism is similar to the rope tensioning mechanism in that the hook strap allows for elasticity and adjustment without causing damage to the shoe and hoof.

The hook strap is made of any belt material that is resilient, durable and easy to use. Preferred materials include plastic with an adhesive portion or an array of hooks and loops that allows attachment to adhere to itself.

An alternative embodiment of the front tensioning mechanism is shown in FIG. Instead of a hook strap and loop adapter system, this embodiment uses the take-up knob 300. The take-up button 300 functions like a cable reel in which the base plate engages the pawl 330 and rotates the take-up knob clockwise until the desired tension is achieved. By moving the take-up knob 300 in the opposite direction, the tension is released. Not only does this release all of the ropes from the rewind button, it also helps to eject dirt and debris under and around the mechanism and facilitates cleaning with a simple brush.

The take-up button 300 utilizes a "high-speed" action to release and wind the ropes 60. The mechanism could be closed, but is preferably an open system that continues to function even in the presence of dirt and debris.

In preferred embodiments, a tether strap 40 couples to the heel cup 30 through strap positions 104. The tether strap 40 stably holds the tether bone, which increases grip in the shoe in use, particularly in extreme conditions such as deep water, snow or mud galloping.

Preferably, the tether strap is made of nylon or other suitable materials which can be adjusted and released by means of a retaining cam buckle 306 or a hook and loop fastener.

In yet another preferred embodiment, an optional liner 70 as shown in Figures 15 and 16 may be incorporated into the heel holder for additional cushioning. Preferably, neoprene is used, but other suitable materials and fabrics that are comfortable and fit with the body, including viscoelastic foams, are provided. The liner 70 has a center strap 250 and two side straps 252 which can be securely fastened by means of the holes of the heel holder 30. The straps may use Velcro or other suitable fastening means to secure the heel holder. The liner provides comfort to the hoof without causing chafing and abrasion in the area. It can be quickly and easily installed or removed with the strap or Velcro fastener.

In yet another preferred embodiment, the liner 70 has holes corresponding to the open mesh of the heel holder to release foreign matter trapped between the shoe and the hoof. Various sizes are provided for the lining. Depending on the size, the lining can be wrapped over the front, side and all other directions of the tether bone. Various shapes are also provided, including a full height liner, shown in FIG. The tether 40 can stably hold the liner over the ankle bone area of the hoof.
