Snowshoe with Sole Comprising Crampon Areas

Abstract

A snowshoe with a base structure forming a flotation zone having a plurality of transverse tread elements ( 20 ) of substantially elongate shape. The tread elements ( 20 ) have front lateral walls ( 25 ) and rear lateral walls ( 26 ),In the front portion of the flotation zone, at least a portion of the tread elements ( 20 ) have a rear lateral wall ( 26 ) that is inclined toward the rear of the snowshoe; and in the rear portion of the flotation zone, at least a portion of the tread elements ( 20 ) have a front lateral wall ( 25 ) that is inclined toward the front of the snowshoe.

1 . A snowshoe having: a base structure forming a flotation zone, said snowshoe comprising: a contact face and a securing face, said flotation zone comprising, on the contact-face side:
 (i) a plurality of tread elements made of elastomeric material and arranged over all or part of a foot zone, said tread elements being of elongate shape, passing across the flotation zone over a width greater than 25% of the width of the flotation zone in which said tread elements are situated, said tread elements comprising front lateral walls and rear lateral walls;   (ii) in the front portion of the flotation zone, at least a portion of the tread elements comprise a rear lateral wall that is inclined in such a way that the a free edge ridge of this the rear lateral wall is offset toward the rear of the snowshoe compared with the edge ridge contiguous with the rest of the sole;   (iii) in the rear portion of the flotation zone, at least a portion of the tread elements comprise a front lateral wall that is inclined in such a way that a free edge ridge of the front lateral wall is offset toward the front of the snowshoe compared with the edge ridge contiguous with the rest of the sole,   wherein said snowshoe comprises a plurality of elongate peripheral tread elements made of elastomeric material, oriented in the longitudinal direction of the snowshoe, arranged over at least one of the lateral overhangs, said tread elements comprising outside lateral walls and inside lateral walls, at least part of the peripheral tread elements comprising an inside lateral wall that is inclined in such a way that the free edge ridge of this wall is offset towards the centre of a sole of the snowshoe compared with the edge ridge contiguous with the rest of the sole.   
     
     
         2 . (canceled) 
     
     
         3 . The snowshoe according to  claim 1 , wherein the inclination of the inclined walls is between 5° and 30. 
     
     
         4 . The snowshoe according to  claim 1 , wherein said tread elements are continuous or discontinuous. 
     
     
         5 . The snowshoe according to  claim 1 , wherein said tread elements pass across the foot zone over a width greater than 50% of the width of the foot zone in which said tread elements are situated. 
     
     
         6 . The snowshoe according to  claim 1 , wherein said tread elements have their main axis substantially parallel to the transverse axis of the snowshoe. 
     
     
         7 . The snowshoe according to  claim 1 , wherein said tread elements are substantially rectilinear. 
     
     
         8 . The snowshoe according to  claim 1 , wherein said tread elements are in the shape of a “V”. 
     
     
         9 . The snowshoe according to  claim 1 , wherein said tread elements are arranged in such a way that their main axis forms an angle, alpha, smaller than 60° with respect to a transverse axis of the snowshoe. 
     
     
         10 . The snowshoe according to  claim 2 , wherein the inclination of the inclined walls is between 8° and 20°. 
     
     
         11 . The snowshoe according to  claim 8 , wherein the angle alpha is smaller than 45°.
