Device for the angular orientation of a boot on a gliding or rolling board

Abstract

A device for the angular orientation of a boot to be associated with a gliding or rolling board. The device includes a disk and a plate, the disk having a peripheral toothing. The plate is rotationally guided in relation to the disk. The plate is provided with an arm that has a toothed end. The arm is journalled with respect to tie plate along an axis that is parallel to the thickness of the plate, and an elastic mechanism biases the arm such that the toothed end of the arm is engaged with the peripheral toothing of the disk.

What is claimed is:  
     
         1 . A device for the angular orientation of a boot to be associated with a gliding or rolling board, the device comprising: 
 a disk and a plate, the disk having a peripheral toothing, the plate being rotationally guided in relation to the disk along an axis substantially perpendicular to a thickness of the plate and to the thickness of the disk, the plate being provided with an arm having a toothed end, the arm being journalled with respect to the plate along an axis substantially parallel to the thickness of the plate, and an elastic mechanism biasing the arm such that the toothed end of the arm is engaged with the peripheral toothing of the disk.    
     
     
         2 . A device according to  claim 1 , wherein the arm is housed in a channel provided in the plate.  
     
     
         3 . A device according to  claim 2 , wherein the channel is oriented longitudinally, in a direction substantially perpendicular to the axis of an opening of the plate provided to receive the disk.  
     
     
         4 . A device according to  claim 1 , wherein the journal axis of the arm is contained in a plane which also contains the peripheral toothing of the disk.  
     
     
         5 . A device according to  claim 1 , wherein the profile of the teeth of the disk is obtained by a generating line parallel to the axis of the disk, and wherein the profile of the teeth of the arm is obtained by a generating line perpendicular to the thickness of the arm.  
     
     
         6 . A device according to  claim 1 , wherein a handle is connected to the arm.  
     
     
         7 . A device according to  claim 6 , wherein the handle is arranged laterally with respect to the device.  
     
     
         8 . A device according to claims  1 , wherein the elastic mechanism that biases the arm, such that the toothed end of the arm is engaged with the peripheral toothing of the disk, is a spring.
