Abstract
Interface device between a ski and front and rear bindings (3, 4), designed to hold in place the ends of a boot on the ski. The device comprises a longilinear plate (15), each end of which is fastened to the ski to the front and rear of the bindings. One end (16) of the plate is attached to the ski. The other end (23) of the plate is movable in relation to the ski, and linkage (24) exerts a force against a block (20) fastened to the ski, thereby pretensioning the plate (15) under traction, and, by reaction, prestressing the central portion of the upper ski surface under compression. Preferably, this pretensioning ceases beyond a determinate ski flection.
Claims18
Interface device adapted to be inserted between a ski and front and rear bindings retaining ends of a boot on said ski, said device comprising
- (a) a longilinear plate adapted to be positioned atop a central portion of a ski, said plate being inextensible and rigid in flexion and having first and second ends adapted to be connected to said ski;
- (b) said plate having toward one end thereof a front mounting zone for attachment of a front binding, and a rear mounting zone for receiving a rear binding;
- (c) a first end of said plate being adapted for rigid attachment to said ski, while a second end of said plate is movable relative to said ski solely longitudinally of said ski during flexion of said ski;
- (d) a block being adapted to be attached to said ski under said second end of said plate;
- and
- (e) a first support stop establishing a unidirectional support connection between said second end of said plate and said block such that said plate is constrained in traction and, in reaction, said central portion of said ski between said block and said first end of said plate is constrained in compression when said ski is at rest.
