Abstract

Abstract A ski board including an elongated riding platform, a pair of mounting brackets, a pair of skis, and resilient means for joining the skis. The elongated riding platform is of a length sufficient to permit a person to stand on the platform with one foot in front of the other. The mounting brackets are attached to the underside of the elongated riding platform in longitudinally spaced relationship. The skis are attached to the mounting brackets in longitudinally aligned relationship for pivotal movement about horizontal axes. The resilient means for joining the skis connects the rear edge of the leading ski to the tip of the trailing ski. With this construction, the trailing ski will track the leading ski over uneven terrain without the possibility of bottoming out.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 191 words
A ski board comprising an elongated riding platform, a pair of mounting brackets attached to the underside of said riding platform in longitudinally spaced relationship, each of said mounting brackets including means permitting pivotal movement of said mounting bracket about a horizontal and a vertical axis relative to said riding platform, a ski having a curved tip and a planar rear edge attached to each of said mounting brackets in a normal longitudinally aligned position to define a leading ski and a trailing ski wherein said tip of said trailing ski slightly overlaps said rear edge of said leading ski, each of said skis including means permitting pivotal movement of said ski about a horizontal axis relative to said mounting bracket, and means for joining said rear edge of said leading ski to said tip of said trailing ski including a resilient disc and a ski-joining bolt extending therethrough, said joining means limiting pivotal movement of said skis about said horizontal and vertical axes by exerting a force tending to restore said skis to said normal longitudinally aligned position whereby said trailing ski will track said leading ski over uneven terrain.
Claim 2
Dependent Claim 191 words
A ski board comprising an elongated riding platform, a pair of mounting brackets attached to the underside of said riding platform in longitudinally spaced relationship, each of said mounting brackets including means permitting pivotal movement of said mounting bracket about a horizontal and a vertical axis relative to said riding platform, a ski having a curved tip and a planar rear edge attached to each of said mounting brackets in a normal longitudinally aligned position to define a leading ski and a trailing ski wherein said tip of said trailing ski slightly overlaps said rear edge of said leading ski, each of said skis including means permitting pivotal movement of said ski about a horizontal axis relative to said mounting bracket, and means for joining said rear edge of said leading ski to said tip of said trailing ski including a resilient disc and a ski-joining bolt extending therethrough, said joining means limiting pivotal movement of said skis about said horizontal and vertical axes by exerting a force tending to restore said skis to said normal longitudinally aligned position whereby said trailing ski will track said leading ski over uneven terrain.
Claim 3
Dependent Claim 32 words
The ski board of claim 1 in which each of said mounting brackets includes means for adjusting the longitudinal position of said mounting bracket relative to the underside of said riding platform.
Claim 4
Dependent Claim 42 words
The ski board of claim 2 in which said longitudinal adjustment means of each of said mounting brackets includes a slotted block at the upper end of said mounting bracket to receive bolts for attachment to the underside of said riding platform.
Claim 5
Dependent Claim 31 words
The ski board of claim 1 in which each of said skis includes means for adjusting the longitudinal position of said ski relative to the corresponding one of said mounting brackets.
Claim 6
Dependent Claim 44 words
The ski board of claim 4 in which said longitudinal adjustment means of each of said skis includes a plate cooperatively associated with the corresponding one of said mounting brackets having slots to receive screws for attachment to the upper side of said ski.
Claim 7
Dependent Claim 54 words
The ski board of claim 1 in which said means for joining said rear edge of said leading ski to said tip of said trailing ski includes an angle bracket attached to said rear edge of said leading ski and said ski-joining bolt joins said tip of said trailing ski to said angle bracket.
Claim 8
Dependent Claim 65 words
The ski board of claim 6 in which said ski-joining bolt passes through said tip of said trailing ski, a resilient disc and said angle bracket; said ski-joining bolt cooperating with a nut to secure said trailing ski, resilient disc, and angle bracket in assembled relationship; said nut being adjustable to vary the force tending to restore said skis to said normal longitudinally aligned position.
Claim 9
Dependent Claim 22 words
The ski board of claim 1 in which said riding platform includes a toe fitting adjacent the front edge of said platform.
Claim 10
Dependent Claim 22 words
The ski board of claim 1 in which said riding platform includes a roughened surface on the upper side of said platform.
Claim 11
Dependent Claim 29 words
The ski board of claim 1 in which said riding platform includes an impact cushion on the underside of said platform immediately above said tip of said trailing ski.
Claim 12
Dependent Claim 44 words
The ski board of claim 1 in which said riding platform includes a removable rope connected thereto for towing said ski board having a length sufficient to also permit a rider to grip said rope in a standing position on said platform for balance.
