Abstract

Abstract A skateboard has a guide which allows a vertically elongated plunger to pass through a hole in the board. The guide allows the plunger to move up and down, while preventing rotation thereof. At the lower end of the plunger, below the skateboard, is attached a wooden block. A compression spring pushes the block and plunger upwardly. At the upper end of the plunger is attached a transversely extending cylindrical rod. A pedal is disposed at the upper end of the plunger. The brake is actuated by depressing the pedal.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 226 words
A skateboard device comprising: A horizontally disposed skateboard having front and rear ends and having a vertical bore therein adjacent the rear end, said board having top and bottom surfaces; Front and rear roller means secured to the bottom surface of the skateboard intermediate the bore and the front end; First and second guide pieces secured to the top and bottom surfaces respectively each guide piece having a hole aligned with said bore, each hole having two diametrically opposed tongues therein which are spaced from each other, the tongues in one piece being aligned with the tongues in the other piece; a vertical cylindrical plunger extending slidably through the bore, said plunger having oppositely disposed vertical grooves in its outer surface engaged by said tongues whereby the plunger is vertically slidable in the bore but cannot rotate therein, said plunger having an upper end extending above the guide piece on the top surface of the board and a lower end extending below the guide piece on the lower surface of the board; a horizontal pedal secured to the upper end of the plunger; a horizontally elongated block secured to the lower end of the plunger; and a coil spring disposed around the plunger between the handle and the guide piece on the top surface of the board to normally bias the plunger into fully raised position.
