Abstract
Abstract A shock absorbing and protective form of a horseshoe comprises a base that conforms to the shape of the perimeter of the horse's hoof, and from which protrudes a series of podded cleats that are strategically aligned and positioned below the horn of the hoof providing the prerequisite support for the horse. Each podded cleat has an internal air chamber, that when combined with the complying shape of the external wall allows partial or full collapse or deflation of this structural element effecting a most significant degree of cushioning, thus allowing a relatively high durometer elastomer for composition that would not otherwise provide sufficient compressibility, but having physical properties that surmount the factors of abrasion and wear and where such hard materials are identifiable as having a low frictional resistance in comparison to highly compressible, soft elastomers. The invention, wherein the action of the podded cleat is the inward, upward mechanical collapse, is enhanced with the memory retention of given elastomeric compounds thus allowing the podded cleat to recover upon release of load and reattain its original shape and dimensional form.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
144 words
A horseshoe comprising: a base member for attachment to a horse's hoof as a lower part thereof and having a bottom surface; and a plurality of podded cleats extending generally downwardly from the bottom surface of said base member in spaced relationship along at least the area of said bottom surface adjacent the peripheral region thereof to support the horn of the hoof around the peripheral region thereof; each podded cleat comprising a pod of elastomeric material protruding from the bottom surface of said base member, and a hollow cavity within said pod having a size and shape relative to the dimensions of the pod to form a wall surrounding said cavity which facilitates substantial compression of the pod under impact and compressive load by mechanical collapse of said wall to maximize cushioning of the impact and load on the horse's hoof in use.
Claim 2
Dependent Claim
144 words
A horseshoe comprising: a base member for attachment to a horse's hoof as a lower part thereof and having a bottom surface; and a plurality of podded cleats extending generally downwardly from the bottom surface of said base member in spaced relationship along at least the area of said bottom surface adjacent the peripheral region thereof to support the horn of the hoof around the peripheral region thereof; each podded cleat comprising a pod of elastomeric material protruding from the bottom surface of said base member, and a hollow cavity within said pod having a size and shape relative to the dimensions of the pod to form a wall surrounding said cavity which facilitates substantial compression of the pod under impact and compressive load by mechanical collapse of said wall to maximize cushioning of the impact and load on the horse's hoof in use.
Claim 3
Dependent Claim
42 words
A horseshoe as claimed in claim 1 wherein: said elastomeric material has resilient properties which in combination with the shape and size of said pods and hollow cavities therein restore said cleats to a given form upon release of the compressive load.
Claim 4
Dependent Claim
46 words
A horseshoe as claimed in claim 2 wherein: said cleats are aligned in spaced circumferential array, and vary in size, number and arrangement with respect to said base member and each other to accommodate specific impact and load bearing forces for specific areas of the hoof.
Claim 5
Dependent Claim
47 words
A horseshoe as claimed in claim 1 and further comprising: reinforcing filaments within said elastomeric material for improving resistance to wear and abrasion of the cleats; and wherein the composition of said elastomeric material promotes resilient displacement of said cleats under compressive load toward said base member.
Claim 6
Dependent Claim
85 words
A horseshoe as claimed in claim 1 wherein: said base member comprises a rigid metal plate having a shape to support the horn of the hoof in contact therewith; said podded cleats are attached to said metal plate along the entire peripheral region thereof; holes are provided in said metal plate aligned with said cavities so that said cavities extend through said metal plate; and means are provided on said metal plate to facilitate attachment of said metal plate to the horn of the hoof.
Claim 7
Dependent Claim
69 words
A horseshoe as claimed in claim 5 wherein: said base member further comprises a layer of elastomeric material on the bottom of said metal plate and attached to said metal plate to form a laminated base member, said cleats being integral with said elastomeric material layer; and holes are provided through said elastomeric material layer aligned with said cavities so that said cavities extend through said laminated base member.
Claim 8
Dependent Claim
27 words
A horseshoe as claimed in claim 6 wherein: each clat is in the form of a truncated cone having the larger base thereof adjacent said base member.
Claim 9
Dependent Claim
26 words
A horseshoe as claimed in claim 7 and further comprising: a metal cap attached over the outer surface of each cleat for protection against abrasive wear.
Claim 10
Dependent Claim
20 words
A horseshoe as claimed in claim 6 wherein: said rigid metal plate is embedded in said layer of elastomeric material.
Claim 11
Dependent Claim
27 words
A horseshoe as claimed in claim 9 wherein: each cleat is in the form of a truncated cone having the larger base thereof adjacent said base member.
Claim 12
Dependent Claim
26 words
A horseshoe as claimed in claim 10 and further comprising: a metal cap attached over the outer surface of each cleat for protection against abrasive wear.
Claim 13
Dependent Claim
43 words
A horseshoe as claimed in claim 1 wherein: said base member comprises a planar element of elastomeric material integral with said cleats; and holes are provided in said planar element aligned with said cavities so that said cavities extend through said planar element.
Claim 14
Dependent Claim
27 words
A horseshoe as claimed in claim 12 wherein: each cleat is in the form of a truncated cone having the larger base thereof adjacent said base member.
Claim 15
Dependent Claim
27 words
A horseshoe as claimed in claim 1 wherein: each cleat is in the form of a truncated cone having the larger base thereof adjacent said base member.
Claim 16
Dependent Claim
26 words
A horseshoe as claimed in claim 1 and further comprising: a metal cap attached over the outer surface of each cleat for protection against abrasive wear.
