Support plate for an element for retaining a boot on a gliding board

Abstract

A support plate provided to be associated with an element for retaining a boot on a gliding board. It includes a base provided to be affixedly connected to the ski, a pedal fastened to the base, movable on both sides of a centered position, with an upper surface provided to receive the boot sole. A wire spring is fastened to the base on one side, and to the pedal on the other side, and between its points for fastening to the base and the pedal, the spring is bent with at least one elbow.

What is claimed is:  
     
         1 . A support plate provided to be associated with an element for retaining a boot on a gliding board, said support plate comprising: 
 a base to be affixed to the ski;    a pedal fastened to the base, said pedal being mounted for transverse movement on both sides of a centered position with respect to said base, said pedal having an upper surface to receive a sole of the boot;    a wire spring fastening said pedal to said base, said spring having a first side fastened to said pedal and a second side fastened to said base, said fastening of said wire spring to said pedal and said base solely guiding a trajectory of said pedal, and between said first and second sides of said spring fastened to said pedal and said base, said spring includes at least one bend having at least one elbow.    
     
     
         2 . A support plate according to    claim 1   , wherein: 
 said at least one bend of said spring comprises bends having a succession of linear segments and elbows.    
     
     
         3 . A support plate according to    claim 2   , wherein: 
 said spring is symmetrical with respect to a longitudinal median plane;    on opposite sides of said longitudinal median plane, said spring is formed by a succession of three linear segments joined two-by-two by elbows, ones of said segments closest to said longitudinal median plane being joined by a median elbow.    
     
     
         4 . A support plate according to    claim 2   , wherein: 
 beneath said base a recess is provided, a portion of said spring is housed in said recess.    
     
     
         5 . A support plate according to    claim 4   , wherein: 
 said spring includes ends bent generally vertically upwardly and engaged in bores provided in lateral surfaces defining said recess.    
     
     
         6 . A support plate according to    claim 4   , wherein: 
 said base includes a rear portion and a front portion, said rear portion being raised with respect to said front portion;    said pedal is located above said front portion;    a transversely extending surface is provided with a transverse slit demarcating said rear and front portions of said base.    
     
     
         7 . A support plate according to    claim 6   , wherein: 
 said spring includes a median loop extending through said transverse slit.    
     
     
         8 . A support plate according to    claim 1   , wherein: 
 said spring includes a median loop, said pedal being fastened to said median loop of said spring.    
     
     
         9 . A support plate according to    claim 8   , wherein: 
 said spring includes a median loop housed in a recess of said pedal, said recess being sealed by a latch including a plug housed within said loop.    
     
     
         10 . An element for retaining a boot on a ski, said element comprising a support plate according to    claim 1   .  
     
     
         11 . An element for retaining a boot on a ski according to    claim 10   , further comprising: 
 a jaw for engaging a portion of the boot.    
     
     
         12 . An element for retaining a boot on a ski according to    claim 11   , wherein: 
 said jaw is adapted to engage a front end of a boot;    said support plate extends rearwardly of said jaw.
