US4029330A — Cambered skateboard provided with longitudinally …

Claim 1

Independent Claim 162 words

In a skateboard having a longitudinally cambered board made from resilient material capable of limited flexing under the weight of a rider, the skateboard having substantially parallel deck and lower surfaces, and front and back longitudinally spaced trucks mounted to its lower surface for carrying a rider along a path selected by application of pressure to the deck surface; the improvement comprising: first mounting means for permitting longitudinal adjustment of one of the trucks with respect to the board, said first mounting means including: a rigid track assembly having an upper longitudinal surface complementary to the unweighted configuration of a cambered portion of the lower surface of the board, said track assembly being fixed to said cambered portion in surface-to-surface engagement between the upper surface of the track and the lower surface of the board; and releasable means operably engaged between said one truck and said track assembly for selectively fixing the longitudinal position of the truck relative to the track assembly.

Claim 2

Dependent Claim 162 words

In a skateboard having a longitudinally cambered board made from resilient material capable of limited flexing under the weight of a rider, the skateboard having substantially parallel deck and lower surfaces, and front and back longitudinally spaced trucks mounted to its lower surface for carrying a rider along a path selected by application of pressure to the deck surface; the improvement comprising: first mounting means for permitting longitudinal adjustment of one of the trucks with respect to the board, said first mounting means including: a rigid track assembly having an upper longitudinal surface complementary to the unweighted configuration of a cambered portion of the lower surface of the board, said track assembly being fixed to said cambered portion in surface-to-surface engagement between the upper surface of the track and the lower surface of the board; and releasable means operably engaged between said one truck and said track assembly for selectively fixing the longitudinal position of the truck relative to the track assembly.

Claim 3

Dependent Claim 41 words

A skateboard as set out in claim 1 wherein the cambered portion of the board immediately above said track is substantially more narrow in transverse width than the transverse width of the board along its length between the longitudinally spaced trucks.

Claim 4

Dependent Claim 23 words

A skateboard as set out in claim 2 wherein the remaining truck is mounted at a stationary position with respect to the board.

Claim 5

Dependent Claim 83 words

A skateboard as set out in claim 1 wherein said track assembly and said one truck are located adjacent the front or nose of the board and wherein the cambered portion of the board immediately above said track assembly is in the form of an elongated narrow tongue having a width substantially less than the transverse width of the board along its length between the longitudinally spaced trucks, there being an abrupt increase in the board width immediately rearward of said track assembly.

Claim 6

Dependent Claim 119 words

A skateboard as set out in claim 1 further comprising: second mounting means spaced longitudinally from said first mounting means for permitting longitudinal adjustment of a second truck with respect to the board, said second mounting means including: a rigid track assembly having an upper longitudinal surface complementary to the unweighted configuration of a cambered portion of the lower surface of the board, said track assembly being affixed to said cambered portion in surface-to-surface engagement between the upper surface of the track assembly and the lower surface of the board; releasable means operably engaged between the second truck and said last-named track assembly for selectively fixing the longitudinal position of the second truck relative to said last-named track assembly.

Claim 7

Dependent Claim 20 words

A skateboard set out in claim 1 wherein the upper longitudinal surface of the track has a concave longitudinal curvature.

Claim 8

Dependent Claim 21 words

A skateboard as set out in claim 1 wherein the upper longitudinal surface of the track has a convex longitudinal curvature.

Claim 9

Dependent Claim 35 words

A skateboard as set out in claim 1 wherein the track comprises a pair of transversely spaced rails identical to one another and fixed to the board in a parallel side-by-side relationship to one another.

Claim 10

Dependent Claim 97 words

A skateboard as set out in claim 1 wherein the track comprises a pair of transversely spaced rails identical to one another and fixed to the board in a parallel side-by-side relationship to one another; the lower surface of each rail being planar; said truck having an upwardly facing flat mounting surface complementary to the planar lower surfaces of the rails for surface-to-surface engagement therewith; said releasable means being connected between the truck and the respective rails to maintain the mounting surface of the truck in a fixed position engaged against the lower surface of each rail.
