Abstract

Abstract This is a sporting wishbone or Y-shaped board for supporting one or two riders in sliding over water or snow. The single bottom arm of the Y is as wide as the combined width of the two front arms of the Y plus the space in between, or approximately 16" to 18", being the total length of the sled 5' to 6'. The medial edges of the two front arms have a built up lip that gently starts from zero at their front tips and slowly becomes 3" to 4" tall near the crotch of the Y-shaped sled. At the very crotch, this built up lip is humped up 14" off the flat bed of the sled to form a racing bicycle seat-like cusp. The widest, single arm of the Y, smoothly curves upward towards the end of the sled forming a gentle letter S in longitudinal section, being the end of this curved up elevation approximately 14" over the flat bed of the sled. Symmetrical sets of fixed, soft straps are placed at various points to hold the rider's feet in the different positions possible for one or two riders for facing either opposite end of the sled. A small, downward pointing stabilizing fin is provided below the wide section.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 548 words
A one piece water and snow gliding board, a sled, biforked as a wishbone or letter Y, capable of supporting one or two riders, one behind the other, in the positions of standing, sitting, kneeling or lying, and capable of traveling in either of two opposite directions, comprising: a pair of ski-like members that represent the front of said sled when traveling in a first direction, front part that, as a fork, has the two said ski members symmetrical to one another with a free space in between and which measures, from the front tips of said skis to the point of bifurcation or crotch, 1/2 to 3/5 of the total length of said sled; a wide section that is the rear of said sled when traveling in said first direction, wide section that is approximately as wide as the combined width of the two said ski members plus their in-between free space, being the front-to-rear length of said wide section, from said crotch of said sled to its rear end 2/5 to 1/2 of the total length of said sled; a humped up seat, extruded out of the said crotch area of the said sled, seat that rises 12" to 16" above said sled and which is capable of accomodating one sitting rider when said sled travels in either of said opposite directions; an extruded up-turned lip that is formed, as a continuum, by the medial edges of the two said ski members, up-turned lip that starts at zero at the front of each ski member and gradually rises to 3" to 4" towards the said crotch of said sled, at which crotch area said lip is built up to form said humped-up seat; a vertical, down-pointing fin parallel with both said directions of traveling, located at the undersurface of the said wide section of said sled; a first foot receiving means for engaging the feet of the front rider traveling in said first direction when said rider sits on said humped-up seat with his/her feet placed over the front of the said ski members; a second foot receiving means for engaging the feet of the said front rider when said rider stands at mid-length of the said ski members and traveling in the said first direction with a second rider accomodated at the rear of said sled; a third foot receiving means for engaging the feet of a single standing rider when said rider places his/her weight on the sides of the said humped-up seat and traveling in the said first direction; a fourth foot receiving means for engaging the feet of the rider in various positions of standing, sitting and kneeling and facing the said rear of said sled and traveling in the said second direction; a first tow-rope engaging means shaped as a down-pointing hook and mounted at the front tip of the said humped-up seat, front of tip so considered when traveling in said first direction; a second tow-rope engaging means shaped as a down-pointing hook and mounted at the very rear of said sled, rear so considered when traveling in said first direction; a pair of hook/eye rings placed, each one respectively, at the very front tips of the said ski members, front tips so considered when traveling in said first direction.
Claim 2
Dependent Claim 548 words
A one piece water and snow gliding board, a sled, biforked as a wishbone or letter Y, capable of supporting one or two riders, one behind the other, in the positions of standing, sitting, kneeling or lying, and capable of traveling in either of two opposite directions, comprising: a pair of ski-like members that represent the front of said sled when traveling in a first direction, front part that, as a fork, has the two said ski members symmetrical to one another with a free space in between and which measures, from the front tips of said skis to the point of bifurcation or crotch, 1/2 to 3/5 of the total length of said sled; a wide section that is the rear of said sled when traveling in said first direction, wide section that is approximately as wide as the combined width of the two said ski members plus their in-between free space, being the front-to-rear length of said wide section, from said crotch of said sled to its rear end 2/5 to 1/2 of the total length of said sled; a humped up seat, extruded out of the said crotch area of the said sled, seat that rises 12" to 16" above said sled and which is capable of accomodating one sitting rider when said sled travels in either of said opposite directions; an extruded up-turned lip that is formed, as a continuum, by the medial edges of the two said ski members, up-turned lip that starts at zero at the front of each ski member and gradually rises to 3" to 4" towards the said crotch of said sled, at which crotch area said lip is built up to form said humped-up seat; a vertical, down-pointing fin parallel with both said directions of traveling, located at the undersurface of the said wide section of said sled; a first foot receiving means for engaging the feet of the front rider traveling in said first direction when said rider sits on said humped-up seat with his/her feet placed over the front of the said ski members; a second foot receiving means for engaging the feet of the said front rider when said rider stands at mid-length of the said ski members and traveling in the said first direction with a second rider accomodated at the rear of said sled; a third foot receiving means for engaging the feet of a single standing rider when said rider places his/her weight on the sides of the said humped-up seat and traveling in the said first direction; a fourth foot receiving means for engaging the feet of the rider in various positions of standing, sitting and kneeling and facing the said rear of said sled and traveling in the said second direction; a first tow-rope engaging means shaped as a down-pointing hook and mounted at the front tip of the said humped-up seat, front of tip so considered when traveling in said first direction; a second tow-rope engaging means shaped as a down-pointing hook and mounted at the very rear of said sled, rear so considered when traveling in said first direction; a pair of hook/eye rings placed, each one respectively, at the very front tips of the said ski members, front tips so considered when traveling in said first direction.
