Abstract
Abstract A training device for skiers in the form of a pair of skate boards for attachment to the feet of the skier and adapted for sidewise rolling movement over a supporting floor surface with a friction brake responsive to sidewise tilting or ''''edging'''' of the boards to control sidewise rolling while permitting sidewise pivoting of the boards.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
109 words
A ski training device comprising an elongated, generally flat board for attachment to the foot of a person; wheel-supporting axle means carried in depending, relatively spaced parallel relation to the central longitudinal axis of said board; a plurality of wheels rotatively carried on said axle means at spaced intervals along the length of said board and supporting said board for sidewise movement on a supporting surface; and brake means including a friction block carried on said axle means beneath said board and arranged to be pressed into frictional engagement with such supporting surface upon transverse tilting of said board to retard sidewise movement of said board on such surface.
Claim 2
Dependent Claim
109 words
A ski training device comprising an elongated, generally flat board for attachment to the foot of a person; wheel-supporting axle means carried in depending, relatively spaced parallel relation to the central longitudinal axis of said board; a plurality of wheels rotatively carried on said axle means at spaced intervals along the length of said board and supporting said board for sidewise movement on a supporting surface; and brake means including a friction block carried on said axle means beneath said board and arranged to be pressed into frictional engagement with such supporting surface upon transverse tilting of said board to retard sidewise movement of said board on such surface.
Claim 3
Dependent Claim
18 words
A ski training device according to claim 1, wherein said friction block is adjustable longitudinally of said board.
Claim 4
Dependent Claim
48 words
A ski training device accordIng to claim 1, wherein said friction block includes a resiliently compressible member adjacent the undersurface of said board arranged to progressively increase the coefficient of friction between said block and such supporting surface with a progressively increasing angle of tilt of said board.
