STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT
Not applicable.

Not Applicable.
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to revolutionizing the art of horses hoeing. More particularly, the invention relates to forming horseshoes in place, i.e. in situ, rather than fabricating the shoe away from the animal and tacking it to the hoof. More broadly, the invention relates to the addition to hoofs of various animals needing hoof protection. More particularly, the invention provides the benefits of shoeing to horses and other animals in an especially convenient and effective manner. The invention provides, for example, with respect to horseshoes, for the shoeing of horses with a resin composition that sets up instantly in situ on the horse's hoof in the near form of a horseshoe and is then trimmed to a perfect shape. The invention enables the periodic renewal of horseshoes with a minimum of effort, readily affords local variation in shoe thickness to compensate for hoof irregularities, and ensures an effective protection for the horse's hoof.
2. Description of the Related Art
Horseshoes have been fabricated of metals for centuries and more recently from synthetic materials, but always by prefabricating the shoe and then applying the prefabricated shoe onto the horse's hoof. See, for example, U.S. Pat. No. 5,699,861 to Sigafos where a kit for horses hoeing is described. The problems of prefabricated horseshoes, whether of metal or plastic is that the shape of the hoof to be shod varies making the application of a prefabricated shoe a process of trial and error, and a highly skilled and expensive to obtain art. Also, some hoofs need a thicker section in one place than in another. It is economically infeasible to market or inventory all the possibilities that may be encountered.
BRIEF SUMMARY OF THE INVENTION
What is needed is a more flexible approach, one that allows customizing of the shoes to the hoof on site without onerous or costly effort. It is accordingly an object of the invention to provide an in situ shoeing method and product. It is a further object to provide a system for the creation on the hoof itself of the shoe. It is a further object to reduce inventory requirement to merely a variously applicable resin system that is applied to the hoof in custom fashion without custom inventory. A further object of the invention is to deposit onto a prepared hoof shoeing surface a resin mass, that may comprise an intimate admixture of reactive resin components, in a profile approximating the intended shoe, that is malleable albeit non-flowing when applied, and modifiable to the desired exact contour to achieve any thickness, any thickness variation along the extent of the shoe, and of course a precise registration of the deposited resin system with the hoof contour without difficult bending of strong, prefabricated materials. It is a still further object to provide a mass resin system typically comprising A and B sides of a resin in the form of reactive thermosetting resin precursors, e.g. comprising urethane resin precursors, that is thixatroped to have a consistency allowing the resin during reaction to a formed, cured or hardened to a state to stand on the hoof shoeing surface without excessive flow off the surface. A further object is the provision of an animal or horse shoe of an intended profile comprising the resin mass in substantially the intended profile in situ on a horse hoof surface, more particularly a synthetic organic resin horseshoe formed in situ on a horse hoof surface, and the combination of a horse having a hoof, and a synthetic organic resin horseshoe attached to said hoof, the horseshoe having been formed in situ from the resin mass on the horse hoof. Other objects include: forming while shoeing a moisture barrier on the hoof surface, through the adhesion of the applied resin mass to the hoof surface material; providing a repair system for shoed hooves by addition of more resin mass where wear has occurred, which is effective because the resin mass in many embodiments will adhere to its previously cured self; preventing the horse from pulling a shoe, i.e. removing a shoe on an adjacent hoof with another hoof through a purchase gained at the so-called lip protruding rearwardly from the conventional horseshoe by eliminating the lip protrusion altogether with careful tailoring of the shoe so as to be narrow on the hoof; equalizing pressure on the hoof all about the hoof surface as an improvement over the use of nails which become as many as seven or more points of pressure; enabling shoeing of horses whose hooves are worn too much to tolerate nailing, but will accept a shoe formed in situ; adding spring to the horse's step through the resiliency of the in-situ-formed horseshoe, the profile of which can be modified to add a spring function; improving traction by customizing the shoe bottom surface to the anticipated terrain; adding color at the shoe, bodily or in accents, or other optical effects including patterns and glitter to reflect the stable that trained the horse, or a cause or event; and to have or provide a layer of resiliency at the hoof for comfort and longevity of the horse.
These and other objects of the invention to become apparent hereinafter are realized in the method for building a horseshoe of an intended shape in situ, including cleaning the surface of the shoe area of horse hoof of debris, shaping a temporarily generally malleable mass of resin on the cleaned hoof surface into generally a horseshoe-shape, and locally modifying the exposed surfaces of the horseshoe mass to conform to the final intended horseshoe shape on the shoe area surface after general malleability in the resin is lost, and the horseshoe product of the method.
In this and like embodiments, typically, the resin selected is one that self-adheres to the shoe area surface, and there is included also precoating the shoe area surface under the mass with a thin layer of the mass or similar resin having less than 25% of the depth of the intended horseshoe shape, selecting as the resin a reaction product of thermosetting resin precursors, selecting as the resin precursors thermosetting urethane resin precursors.
In a further embodiment, the invention provides a method for building a horseshoe of an intended shape in situ, including cleaning the surface of the shoe area of horse hoof of debris, applying a preshaped mass of resin on the cleaned hoof surface in generally a horseshoe-shape, and precoating the surface with a resin acting to bond the shaped mass to the surface before application of the shaped mass, and the product of the method.
In this and like embodiments, typically, the method further includes locally reshaping the horseshoe mass to conform to the intended horseshoe shape on the shoe area surface, selecting as the precoating resin the same resin as the shaped mass resin.
The invention further provides in combination, the indicated preshaped mass a resin adhesive adhering the mass of resin to the surface, the resin adhesive being distributed on the surface.
In a further embodiment, the invention provides a method for building a horseshoe of an intended shape in situ, including cleaning the surface of the shoe area of a horse hoof of debris, collecting an unconfined malleable resin mass beyond the shoe area surface, applying the mass onto the cleaned hoof surface in a generally horseshoe-shaped form, and then locally modifying the exposed surfaces of the horseshoe mass to conform to the final intended horseshoe shape on the shoe area surface.
In this and like embodiments, typically, the method further includes selecting as the resin mass a mass that self-adheres to the shoe area surface, and selecting as the resin mass a mass comprising a mixture of thermosetting resin precursors, such as thermosetting urethane resin precursors.
In a further embodiment, the invention provides a method for building an animal shoe of an intended shape in situ, including cleaning the
