Abstract
Abstract A protective boot which can be removably attached to the legs of horses, that may be engaged in a variety of activities such as galloping, jumping and the like, in a position extending over the shank and contiguous fetlock joint areas, and which comprise a body portion formed of an outer layer of flexible synthetic plastic sheet material and an inner cushion layer of foamed synthetic plastic material having their confronting surfaces bonded together, the inner layer also being formed to provide a plurality of ribs separated by open-sided grooves extending longitudinally of the body and lengthwise of the horse's leg. Through-going perforations in the grooves and ridges permit evaporation of sweat. Attaching bands or straps are integrally formed with the outer layer of plastic sheet material for engagement by clamping devices, and in which these bands have strengthening fabric inserts and transverse laterally spaced apart ridges to prevent slippage in the clamping device. The holding bands and coacting clamping devices at the fetlock joint area are in converging relation with respect to parallel bands and clamping devices in other areas.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
114 words
A protective boot for application about the leg of a horse, comprising: a main elongate body portion; fastening means for releasably securing the body portion in desired position around a leg portion of the horse; said body portion having an outer flexible backing layer bonded to an inner cushion layer provided with a plurality of longitudinally extending ribs separated by open-sided grooves extending longitudinally of the body portion and substantially lengthwise of the leg when applied thereto, and said body portion being provided with throughgoing perforations in spaced relation, each having ends respectively communicating with the outer contact surfaces of the ribs of the cushion layer and the outer surface of the backing layer.
Claim 2
Dependent Claim
114 words
A protective boot for application about the leg of a horse, comprising: a main elongate body portion; fastening means for releasably securing the body portion in desired position around a leg portion of the horse; said body portion having an outer flexible backing layer bonded to an inner cushion layer provided with a plurality of longitudinally extending ribs separated by open-sided grooves extending longitudinally of the body portion and substantially lengthwise of the leg when applied thereto, and said body portion being provided with throughgoing perforations in spaced relation, each having ends respectively communicating with the outer contact surfaces of the ribs of the cushion layer and the outer surface of the backing layer.
Claim 3
Dependent Claim
36 words
A boot according to claim 1, in which: said body portion includes other perforations in spaced relation, each having ends respectively communicating with the outer surface of the backing layer and the grooves separating said ribs.
Claim 4
Dependent Claim
104 words
A boot according to claim 1, in which: said inner layer is comprised of a foamed synthetic plastic material and said outer layer is comprised of a flexible synthetic plastic sheet material; and said fastening means includes spaced apart elongate securing bands integral with the outer layer material and extending from an edge thereof, and buckles secured along an opposite edge margin of the outer layer respectively having a clamping element for engaging said band, and said bands have transversely extending surface ridges in laterally spaced apart relation longitudinally of the band for opposing slippage between said clamping element and the clamped securing band.
Claim 5
Dependent Claim
17 words
A boot according to claim 3, in which: said bands are bonded to the outer layer material.
Claim 6
Dependent Claim
22 words
A boot according to claim 3, in which: said bands have a tensile strength greater than that of the outer layer material.
Claim 7
Dependent Claim
23 words
A boot according to claim 3, in which: said bands have a layer of longitudinally extending reinforcing material positioned between its opposite surfaces.
Claim 8
Dependent Claim
145 words
A boot according to claim 1, in which: said outer layer is comprised of flexible synthetic plastic sheet material; and said fastening means includes spaced apart elongate securing bands extending from one edge of said layer, and band fastening elements secured along an opposite edge margin of the outer layer for respectively engaging the securing bands and holding the boot in an applied position with the lower marginal portion of the boot extending around the fetlock joint of the leg and with the upper of said bands and associated fastening elements being in substantially parallel relation, and a lower band and associated fastening element being angularly disposed in relation to the upper bands and fastening elements to compensate for the angular displacement of the connected edges of the outer layer at the fetlock joint, and thereby uniformly stress the lower band along its opposite edges.
Claim 9
Dependent Claim
29 words
A boot according to claim 7, in which: the lower band and lower fastening device respectively extend in outwardly converging relation to said parallel upper bands and fastening devices.
