Abstract

Abstract The invention is a manually operated brake for a skateboard which is connected by means of a tether cable to either the front or rear truck, there being two or more alternative means by which the braking of the wheels may be implemented, and the braking cable is disengageable from the skateboard so that the board may be alternatively used in the conventional fashion having no braking capacity.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 299 words
A skateboard assembly having a combination tether and hand brake comrpising: (a) a deck portion having a cleared upper surface to provide a platform for the unfettered feet of the user, said deck portion also having an undercarriage sturcture; (b) a plurality of truck means and support wheels journalled on said truck means in said undercarriage structure beneath said deck permitting steering said skateboard assembly completely by the use of the feet; (c) a frictional member and means mounting same on said skateboard assembly beneath said deck and being movable such that said frictional member can move from a first position clear of said wheels to a second position frictionally engaging at least one of said wheels to brake same; (d) a flexible Bowden wire cable having an outer sheath and an inner core, and doubling as a brake line and a tether, one end of said cable being mounted to said skateboard assembly such that said sheath is substantially immobile relative thereto and said core is connected to said frictional member such that axial motion of said core moves said frictional member between said first and second positions; (e) a hand grip means mounted on the other end of said cable, said hand grip means being operable to displace said core axially relative to said sheath when said hand grip means is squeezed to brake said skateboard assembly, said cable representing the only connection between the rider and said skateboard save standing contact on said platform, whereby the operator of said skateboard may ride same with his feet and body completely unhindered, and upon engaging said hand grip in the hand have said skateboard assembly securely retained on the end of said cable and prevented from escaping and have complete braking control over said skateboard assembly as well.
Claim 2
Dependent Claim 299 words
A skateboard assembly having a combination tether and hand brake comrpising: (a) a deck portion having a cleared upper surface to provide a platform for the unfettered feet of the user, said deck portion also having an undercarriage sturcture; (b) a plurality of truck means and support wheels journalled on said truck means in said undercarriage structure beneath said deck permitting steering said skateboard assembly completely by the use of the feet; (c) a frictional member and means mounting same on said skateboard assembly beneath said deck and being movable such that said frictional member can move from a first position clear of said wheels to a second position frictionally engaging at least one of said wheels to brake same; (d) a flexible Bowden wire cable having an outer sheath and an inner core, and doubling as a brake line and a tether, one end of said cable being mounted to said skateboard assembly such that said sheath is substantially immobile relative thereto and said core is connected to said frictional member such that axial motion of said core moves said frictional member between said first and second positions; (e) a hand grip means mounted on the other end of said cable, said hand grip means being operable to displace said core axially relative to said sheath when said hand grip means is squeezed to brake said skateboard assembly, said cable representing the only connection between the rider and said skateboard save standing contact on said platform, whereby the operator of said skateboard may ride same with his feet and body completely unhindered, and upon engaging said hand grip in the hand have said skateboard assembly securely retained on the end of said cable and prevented from escaping and have complete braking control over said skateboard assembly as well.
Claim 3
Dependent Claim 204 words
In combination, a brake attachment and a skateboard assembly having a deck portion with a plurality of support wheels, including a pair of spaced coaxial wheels, mounted thereto said attachment comprising: (a) a frictional member comprising a bar dimensioned to span said spaced wheels; (b) mounting means mounted to said frictional member and attachable to a skateboard assembly mounting said bar to a skateboard to permit motion of said bar from a first position clear of said wheels to a second position frictionally engaging at least one of said wheels when said frictional member is mounted to a skateboard assembly; (c) a flexible Bowden wire cable having the core thereof connected at one end to said frictional member with the sheath thereof engageable in a seat in said skateboard assembly, said cable being operated at the other end by means of a hand grip means to move said frictional member between said first and second position, whereby the user of said skateboard can brake same manually while riding; and (d) a quick-release means incorporated in said Bowden wire cable to permit quick manual release of said hand grip assembly and at least a portion of said cable to permit conventional operation of said skateboard.
Claim 4
Dependent Claim 204 words
In combination, a brake attachment and a skateboard assembly having a deck portion with a plurality of support wheels, including a pair of spaced coaxial wheels, mounted thereto said attachment comprising: (a) a frictional member comprising a bar dimensioned to span said spaced wheels; (b) mounting means mounted to said frictional member and attachable to a skateboard assembly mounting said bar to a skateboard to permit motion of said bar from a first position clear of said wheels to a second position frictionally engaging at least one of said wheels when said frictional member is mounted to a skateboard assembly; (c) a flexible Bowden wire cable having the core thereof connected at one end to said frictional member with the sheath thereof engageable in a seat in said skateboard assembly, said cable being operated at the other end by means of a hand grip means to move said frictional member between said first and second position, whereby the user of said skateboard can brake same manually while riding; and (d) a quick-release means incorporated in said Bowden wire cable to permit quick manual release of said hand grip assembly and at least a portion of said cable to permit conventional operation of said skateboard.
Claim 5
Dependent Claim 141 words
A skateboard assembly comprising: (a) a deck portion having an undercarriage structure; (b) a plurality of support wheels journalled in said undercarriage beneath said deck; (c) a frictional member and means mounting same on said skateboard assembly beneath said deck such that said frictional member is movable from a first position clear of said wheels to a second position frictionally engaging at least one of said wheels; (d) a flexible Bowden wire cable operably connected at one end to said skateboard assembly to control said frictional member and being operable by means of a hand grip assembly mounted to the other end of said cable to move said frictional member between said first and second position, whereby the user of said skateboard can brake same manually while riding; and (e) a spring-loaded reel mounted to said skateboard for storing said cable.
Claim 6
Dependent Claim 141 words
A skateboard assembly comprising: (a) a deck portion having an undercarriage structure; (b) a plurality of support wheels journalled in said undercarriage beneath said deck; (c) a frictional member and means mounting same on said skateboard assembly beneath said deck such that said frictional member is movable from a first position clear of said wheels to a second position frictionally engaging at least one of said wheels; (d) a flexible Bowden wire cable operably connected at one end to said skateboard assembly to control said frictional member and being operable by means of a hand grip assembly mounted to the other end of said cable to move said frictional member between said first and second position, whereby the user of said skateboard can brake same manually while riding; and (e) a spring-loaded reel mounted to said skateboard for storing said cable.
