Definitions

  • the present invention relates to a snowshoe and more particularly an improvement which improves performance and comfort.
  • Snowshoes have been known for many years because they have been used for centuries by the Scandinavian populations to travel on snow. Until today, snowshoes were used for utility or military purposes, to allow the populations and the alpine troops to move on snow for their displacements necessary for the daily life. Currently, snowshoes are rather used by sportsmen who go for hikes and walks, or even competitions. But athletes, although practicing for their pleasure, are more and more demanding for the equipment they use, and it is true that the products currently sold do not give full satisfaction, especially during progression on difficult snow.
  • the present invention provides a new racket combining both good performance in hooking and support on the ground, while allowing easy progression both uphill and downhill, as well as in crossings.
  • the snowshoe consists of an openwork plate formed by a peripheral frame comprising a vertical wall and a sieve supporting the binding intended to hold the shoe of the user, while the central part is extended towards the front by a front part and towards the rear by a rear part, and is characterized in that the width between the lateral edges of the frame and / or of the screen has in the central part a narrowing in width with respect to the part front and rear, so that the width "Lc" at the narrowing is less than the width "La" of the front part and the width "Le” of the rear part.
  • the width between the lateral edges of the frame and / or the screen varies progressively from front to rear, decreasing from the front part and then increasing as the we get closer to the back.
  • At least one of the lateral edges of the frame and / or of the screen is concave in the central part occupied by the shoe.
  • the two peripheral side walls of the frame have a concave shape on both sides, while in another embodiment the two lateral edges of the screen have a concave shape on both sides.
  • the central part corresponds to the area occupied by the shoe.
  • the maximum narrowing in length that is to say where the frame and / or the sieve is (are) the narrower (s), is advantageously located in the occupied central part by the shoe.
  • Figures 1 to 7 illustrate a first embodiment given by way of example.
  • FIGS 1 to 2 are illustrations showing the racket according to the first embodiment with a binding, which binding is given by way of example.
  • Figure 1 is a top view, but without the shoe.
  • Figure 2 is a side view, the shoe being shown in thin dashed lines.
  • Figures 3 and 4 are views similar to Figures 1 and 2 but without the attachment and on another scale.
  • Figure 5 is a bottom view of Figure 3.
  • FIG. 6 is a view in longitudinal section along VI-VI of FIG. 5.
  • Figures 7a, 7b, 7c, 7d, 7e are sectional views along A-A, B-B, C-C, D-D, E-E, showing the variations in width of the frame.
  • Figures 8, 9, 10a, 10b, 10c, 10d, 10e are views similar to Figures 5, 6 and 7a, 7b, 7c, 7d, 7e.
  • Figure 11 is a top view of another alternative embodiment.
  • Figures 12, 13 and 14 are schematic top views of three alternative embodiments.
  • FIGS 15 and 16 illustrate two other alternative embodiments.
  • the racket designated under the general reference (1) is in the form of an openwork plate of general plane of symmetry (P) fixed under the shoe and which consists of a main frame (2) and a sieve ( 4), comprising a set of walls supporting the binding (5) intended to retain the shoe (6) of the user.
  • Said sieve (4) with its set of internal walls forms a general lower surface for bearing on the snow allowing the user not to sink too far into the snow, thanks to the relatively large bearing surface.
  • the binding (5) for retaining the shoe (6) is, according to the illustration given by way of example, articulated with respect to the screen (4) of the racket itself, along a transverse axis (XX ') .
  • said binding bearing the general reference (5) is constituted by an articulated plate (9) comprising retaining means for the shoe, namely front means (10) and rear means (11).
  • the front end (12) of the shoe is, for example, retained by a front stirrup (13), while its rear end (14) is, thanks to a pivoting rear stirrup (15) comprising a retaining lever (16).
  • the plate (9) is advantageously rigid and extends longitudinally, comprising an upper bearing surface (17) for supporting the sole of the shoe.
  • the racket of the invention can be equipped with any other type of shoe fixing device such as, for example, that described in French patent application No. 94 05919 of the applicant.
  • the racket (1) comprises a central part (20) extended, on the one hand, towards the front (AV) by a slightly raised front part (21) constituting the tip (7) and, on the other hand, towards the 'rear (AR) by a rear zone (22) constituting the heel (8).
  • the frame (2) is constituted by a peripheral wall (3) perpendicular to the general horizontal plane (H) of the screen (4). Let us add that the central part (20) is bordered laterally on each side by the lateral border, on the one hand of the frame (2, 3), and on the other hand, of the screen (4).
  • the central part (20) of the racket (1) is bordered on the left side (GA) by the left side wall (30a) of the frame (2) and by the left side edge (40a) of the screen, while right side (DR) it is bordered by the right side wall (30b) of the frame (2) and by the right side edge (40b) of the screen.
  • the central part (20) is limited at the front by the front transverse plane (P1) separating it from the front part (21), while it is limited at the rear by the rear transverse plane (P2) .
  • the side wall (30a, 30b) of the frame (2) and / or the side edge (40a, 40b) of the screen (4) has a concave curvature in the horizontal plane in the central part (20) of the racket, that is to say to have in this central part a reduced width compared to the width of the front and rear.
  • Figures 1 to 7 show a first embodiment according to which it is the peripheral walls (3) of the frame (2) which have in the central part a concave profile to form a width narrowing (300) at the level of the occupied zone by the shoe.
  • the width "L" between the two side walls (30a, 30b) decreases progressively towards the rear from the front plane (P1) to the middle (P3) corresponding to the most narrow, then gradually increase backwards to the rear plane (P2).
  • the two side walls (30a, 30b) of the frame have a concave configuration curved according to an arc of circle of radius R, the center of the circle being in an area external to the racket (1).
  • Figures 7a, 7b, 7c, 7d, 7e illustrate in different successive sections the progressive variation in width "L” between the two side walls (30a, 30b). It can thus be seen that in section AA, the width “La” is greater than the width "Lb” measured in section BB, and the width “Lc” in the center according to section CC is less than the widths "La” and “Lb ". Similarly, in section EE, the width "Le” is greater than the width "Ld” measured in section DD, and the width "Lc” in the center according to section CC is less than the widths "Le” and "Ld” .
  • peripheral walls of the frame which serve as a hook during progression are close to the foot in the area of the foot and gradually move away from the plane (P) towards the front and towards the rear so that the support on the snow is sufficiently wide in the front and rear part of the racket.
  • the screen (4) was such that its width at the front and at the rear was greater than its width at the center, as illustrated by FIGS. 8, 9 and 10.
  • it is the lateral edges (40a, 40b) of the screen (4) which have in the central part a concave profile to form a width narrowing at the level of the zone occupied by the shoe.
  • the width "L" between the two lateral edges (40a, 40b) decreases progressively towards the rear from the line (XX ') to the middle (22') corresponding to the narrowest area, then gradually increase backwards to the line (YY ').
  • the two lateral edges (40a, 40b) of the frame have a concave configuration curved according to an arc of a circle of radius R, the center of the circle being an area external to the racket (1).
  • Figures 10a, 10b, 10c, 10d, 10e illustrate in different successive sections the progressive variation in width "L” between the two lateral edges (40a, 40b). It can thus be seen that in section AA, the width "La" is greater than the width "Lb” measured in section BB and that the width "Lc” in the center according to section CC is less than the widths "La” and "Lb ". Similarly, in section EE, the width "Le” is greater than the width "Ld” measured in the section DD and the width "Lc" in the center according to section CC is less than the widths "Le” and "Ld".
  • Figure 11 is a top view showing another embodiment in which it is associated the curvatures of the side walls (30a, 30b) of the frame of the embodiment of Figures 1 to 7 and the curvatures of the side edges (40a, 40b) sieve.
  • racket could be asymmetrical, as illustrated in FIGS. 12, 13 and 14 which illustrate three other embodiments of FIGS. 3, 8 and 11 where only the lateral border of one of the sides left or right is concave.
  • Figures 15 and 16 schematically illustrate other possible embodiments.
  • the left and right concave curvatures are asymmetrical with respect to the plane P.
  • another way of providing the concave shape of the borders which are produced by rectilinear segments is illustrated. instead of a curved shape.
  • central part (20) of the racket advantageously corresponds to the area occupied by the binding and the user's shoe.
  • the maximum narrowing in width that is to say where the frame and / or the screen is (are) the narrower (s) is advantageously in the central part occupied by the shoe, as can be clearly seen in the figures.
