Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
181 words
A skateboard comprising: a low elongated substantially horizontal body having a front and a rear end, front and rear ground engaging support wheel means carried by corresponding end portions of said body, the latter being adapted to support a load thereon, and brake means on said body for slowing said body by engagement with the ground in response to pivotal movement thereof by the load supported on said body, said brake means including a substantially planar member, spring hinge means for pivotably connecting said member to the rear end of said horizontal body and biasing said member upwardly relative to said horizontal body, a depending stop on the rear portion of said planar member for engaging the ground upon pivoting said planar member against the bias of said spring hinge means, at least one hook catch pivotably mounted on the bottom surface of said horizontal body adjacent the rear end thereof, and at least one pintle on the bottom surface of said planar member adapted to cooperate with said hook catch to lock said planar member by precluding pivotal movement thereof.
