Abstract
Abstract An elongated horizontal board for standing upon with both feet and of a length approximately five to six times the length of the average shoe and of a width approximately two to three times the length of an average shoe. The forward end of the board is rounded in plan shape and slightly upwardly curved and the rear opposite side marginal edge portions of the board are slightly rearwardly convergent. The rear end quarter of the board is inclined approximately 20* rearwardly and upwardly and includes at least one depending brake member engageable with a surface over which the board is moving when the board is excessively rocked backward over a fulcrum area thereof defined at the juncture of the rear end quarter and forward portion of the board. When the board is rocked moderately rearwardly over the fulcrum area lateral foot pressure in opposite directions in opposite sides of the fulcrum area may be utilized to angularly displace the board about an upstanding axis passing through the fulcrum area for steering purposes.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
177 words
An elongated horizontal board for standing upon with both feet and including a forward end portion which curves upwardly at least slightly toward its forward extremity, a substantially planar rear end portion which is angled rearwardly and upwardly toward its rear end, and a generally straight horizontal center portion interconnecting said front and rear end portions, the undersurface portions of said board at the juncture of said rear end portion and said center portion defining a fulcrum area onto which said board may be rearwardly rocked by greater downward foot pressure on the rear end portion from above preparatory to foot pressure being applied to either side of said board for changing the direction of forward motion, guide means disposed longitudinally on the undersurface portion of said center portion for guiding said board in a forward direction and extended to said fulcrum area, said rear end portion being formed with a depending friction brake member defining at least one transverse abutment the lowermost end of which terminates above a plane containing the undersurface of said central portion.
Claim 2
Dependent Claim
177 words
An elongated horizontal board for standing upon with both feet and including a forward end portion which curves upwardly at least slightly toward its forward extremity, a substantially planar rear end portion which is angled rearwardly and upwardly toward its rear end, and a generally straight horizontal center portion interconnecting said front and rear end portions, the undersurface portions of said board at the juncture of said rear end portion and said center portion defining a fulcrum area onto which said board may be rearwardly rocked by greater downward foot pressure on the rear end portion from above preparatory to foot pressure being applied to either side of said board for changing the direction of forward motion, guide means disposed longitudinally on the undersurface portion of said center portion for guiding said board in a forward direction and extended to said fulcrum area, said rear end portion being formed with a depending friction brake member defining at least one transverse abutment the lowermost end of which terminates above a plane containing the undersurface of said central portion.
Claim 3
Dependent Claim
