Snowshoe with a climbing bar

Abstract

A snowshoe comprising a frame, a plate, a first pivot linkage of transverse axis being laid out between the front portion of the plate and the front portion of the frame, and a cleat [pivotally mounted with the back portion of the frame by means of a second pivot linkage of transverse axis. The cleat comprises at least one transverse axial portion extended with a cylindrical portion and the frame comprises at least one transverse bored portion for receiving the cylindrical portion. Position holding means are laid out between the frame and the axial portion on the cleat so that said cleat may be at least held in an abutment position under the back portion of the plate and be retracted upon imposed initiation of pivoting.

1 . A snowshoe comprising a frame, a plate provided with means for attaching a shoe, a first pivot linkage with a transverse axis being laid out between the front portion of the plate and the front portion of the frame so as to allow angular displacement towards the top of the plate with respect to a rest position according to which said plate is substantially located in the plane of the frame, and a cleat pivotally mounted with the back portion of the frame by means of a second pivot linkage with a transverse axis so as to pivot the cleat from a retracted position according to which the plate may be positioned in the rest position, to an abutment position according to which said cleat is supported under the back portion of the plate in order to maintain a minimum angular displacement of the plate with respect to the frame, wherein the cleat comprises at least one transverse axial portion extended with a cylindrical portion and the frame comprises at least one transverse bored portion for receiving the cylindrical portion, and in that position holding means are laid out between the frame and the axial portion on the cleat in order to allow said cleat to be held at least in an abutment position and to retract upon imposed initiation of pivoting. 
     
     
         2 . The snowshoe according to  claim 1 , wherein the cleat has at least one portion with the shape of a U turned upside down provided with a base and two side branches the base being supported under the back portion of the plate in the abutment position, both branches having their ends, bent in the opposite transverse direction and coaxially, said bent ends each forming a transverse axial portion extended with a cylindrical portion. 
     
     
         3 . The snowshoe according to  claim 1 , wherein the cylindrical portion is formed by a cylindrical head added to the end of the axial portion. 
     
     
         4 . The snowshoe according to  claim 1 , wherein the position holding means comprise at least one flat laid out on the axial portion, the position of the flat corresponding to the abutment position of the cleat, and a blocking part subjected to the frame, the blocking part comprising at least one flexible leaf held in the compressed condition so as to bear upon the axial portion in order to block rotation of the cleat when the leaf is flattened on the flat. 
     
     
         5 . The snowshoe according to  claim 4 , wherein the axial portion comprises at least two flats, the positions of which respectively correspond to the abutment position and to the retracted position of the cleat according to which the leaf is flattened on the corresponding flat. 
     
     
         6 . The snowshoe according to  claim 5 , wherein the axial portion comprises two pairs of flats each respectively corresponding to the abutment position and to the retracted position of the cleat, the blocking part comprising two flexible leaves flattened on one of the pairs of flats depending on the position of the cleat. 
     
     
         7 . The snowshoe according to  claim 6 , wherein the blocking part comprises at least one U-shaped portion, the branches of which form both flexible leaves. 
     
     
         8 . The snowshoe according to  claim 7 , wherein the blocking part comprises a second portion forming a bottom firmly attached to the base of the U of the first portion, said bottom comprising an orifice for letting through the cylindrical portion of the cleat. 
     
     
         9 . The snowshoe according to  claim 6 , wherein the frame comprises an accommodation area having at least two lateral sides, said area giving the possibility of at least receiving and holding in the compressed state two flexible leaves of the blocking part on said lateral sides. 
     
     
         10 . The snowshoe according to  claim 9 , wherein the ends of both flexible leaves are bent outwards, the flexible bent portions bearing upon the lateral sides of the accommodation area by exerting a return of the leaves bearing against the pair of flats. 
     
     
         11 . The snowshoe according to  claim 9 , wherein the accommodation area has the shape of a U, the base of which allows reception of the base of the first portion of the blocking part. 
     
     
         12 . The snowshoe according to  claim 11 , wherein the U-shaped accommodation area is open on the lower face of the frame of the snowshoe. 
     
     
         13 . The snowshoe according to  claim 9 , wherein a sealed closure system is laid out so as to be added onto the frame and to make the accommodation area hermetically sealed. 
     
     
         14 . The snowshoe according to  claim 4 , according to which the blocking part is made in spring stainless steel. 
     
     
         15 . The snowshoe according to  claim 4 , wherein at least the flexible leaf(ves), of the blocking part has(have) a hardness comprised between 30 and 35 HRC and a thickness comprised between 0.3 and 0.6 mm. 
     
     
         16 . The snowshoe according to  claim 2 , wherein blocking means are laid out between the cleat and the frame for delimiting the retracted position of the cleat and the abutment position of the cleat upon pivoting the latter with respect to said frame, to either one of said positions. 
     
     
         17 . The snowshoe according to  claim 16 , wherein two extensions are laid out substantially at right angles at the lower portions of the side branches while extending towards the rear of the snowshoe, the shapes of the side branches and of the lateral sides of the frame being laid out so as to come into abutment on each other in the retracted position of the cleat, also the shapes of the extensions and of the lateral sides of the frame are laid out so as to come into abutment on each other in the abutment position of the cleat. 
     
     
         18 . The snowshoe, according to  claim 17 , wherein the upper portions of the side branches and the rear ends of the extensions each comprise a notch laid out so as to notably receive the tip of a stick.
