Abstract

Abstract The ski structure has a front ski and a rear ski, vibration dampers and a mechanism for converting a lateral pressure into a rotary motion, associated with one of the skis. The front and rear skis can be temporarily mutually loosely interconnected by at least one tab and can be rigidly interconnected by a removable mechanical bridge. Thus, the rear ski follows the direction assumed by the front ski, and the ski structure can be disassembled for easy transport.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 193 words
Ski structure comprising; a front ski having a rear end, an upper surface provided on said rear end of said front ski, a rear ski, means for dampening vibration connected to one of said front ski and said rear ski, means for converting a lateral pressure into a rotary motion being associated with one of said front ski and said rear ski, at least one tab, said tab temporarily mutually loosely interconnecting said front ski and said rear ski, and a removable mechanical bridge rigidly connecting said front ski and said rear ski, wherein said front ski and said rear ski have different lengths, wherein said tab protrudes in front of said rear ski, said tab having a slightly smaller thickness than said rear ski, said tab furthermore having a slightly inclined configuration and lying on a plane, said plane being parallel to, and higher than said rear end of said front ski, wherein said ski structure further comprises a spoiler defined at said rear end and protruding from said upper surface of said rear end, and wherein said tab of said rear ski is positioned between said spoiler and said upper surface.
Claim 2
Dependent Claim 193 words
Ski structure comprising; a front ski having a rear end, an upper surface provided on said rear end of said front ski, a rear ski, means for dampening vibration connected to one of said front ski and said rear ski, means for converting a lateral pressure into a rotary motion being associated with one of said front ski and said rear ski, at least one tab, said tab temporarily mutually loosely interconnecting said front ski and said rear ski, and a removable mechanical bridge rigidly connecting said front ski and said rear ski, wherein said front ski and said rear ski have different lengths, wherein said tab protrudes in front of said rear ski, said tab having a slightly smaller thickness than said rear ski, said tab furthermore having a slightly inclined configuration and lying on a plane, said plane being parallel to, and higher than said rear end of said front ski, wherein said ski structure further comprises a spoiler defined at said rear end and protruding from said upper surface of said rear end, and wherein said tab of said rear ski is positioned between said spoiler and said upper surface.
Claim 3
Dependent Claim 132 words
Ski structure according to claim 1, wherein said mechanical bridge has bridge ends, said bridge ends being connected to said means for dampening vibration, said mechanical bridge being constituted by a first half-bridge and a second half-bridge, said ski structure further comprising means for mutually temporarily engaging said first half-bridge and said second half-bridge, wherein said first half-bridge has a first half-bridge free end, and wherein said second half-bridge has a second half-bridge free end, an engagement element protruding at said first half-bridge free end, said engagement element being constituted by a bar, said bar having an end, a hook protruding from said end of said bar, said hook removably engaging an eccentric pivot, said eccentric pivot being rotatably connected transversely to said second half-bridge proximate to said second half-bridge free end.
Claim 4
Dependent Claim 199 words
Ski structure according to claim 1, wherein said mechanical bridge has bridge ends, said bridge ends being connected to said means for dampening vibration, said mechanical bridge being constituted by a first half-bridge and a second half-bridge, said ski structure further comprising means for mutually temporarily engaging said first half-bridge and said second half-bridge, wherein said first half-bridge has a first half-bridge free end, and wherein said second half-bridge has a second half-bridge free end and a lower surface, an engagement element protruding at said first half-bridge free end, said engagement element being constituted by a bar, said bar having an end, a hook protruding from said end of said bar, said hook removably engaging an eccentric pivot, said eccentric pivot being rotatably connected transversely to said second half-bridge proximate to said second half-bridge free end, and wherein said eccentric pivot has eccentric pivot ends, said eccentric pivot ends being connected to a handle, said handle being located external to said second half-bridge, said handle having wings, said wings being connected to a base, said base being arranged parallel and adjacent to said lower surface of said second half-bridge during mutual securing of said hook and said eccentric pivot.
