Definitions
- the invention relates to a snowshoe having a support frame with an elongated structure and provided with a vertical peripheral wall delimiting an internal surface perforated by ribs to constitute a sieve, which comprises an intermediate part extending at the rear. by a tail and at the front by a spatula.
- Document EP-A-613 704 relates to a snowshoe having a flat sieve throughout the intermediate part.
- the lower surface of the screen comprises internal attachment walls, the lower edge of which protrudes below the attachment plane of the peripheral frame.
- the lift of the sieve on the ground and the hanging on a slope remain limited for a predetermined surface of the racket.
- Document FR-A-2772628 describes a snowshoe whose lateral sides of the frame have a profile in the shape of a vault extending outward and beyond the lateral flat edges of the frame.
- the presence of the vault stores and compresses a quantity of snow under the sieve to reduce the sinking in powdery or soft snow.
- the vault nevertheless increases the coefficient of penetration in the snow, which slows down the advancement for a given effort.
- the object of the invention consists in making a snowshoe of simple structure, having good grip and hooking on a slope, and facilitating sliding during advancement, regardless of the quality of the snow.
- V a pair of lateral support surfaces arranged in V, and connected at the front and at the rear respectively by wings and extensions so as to constitute a V-profile symmetrical with respect to the longitudinal median plane of the racket .
- the beam has an inverted U-shaped contour.
- the V-profile of the screen has an inclination with an obtuse angle of between 120 ° and 170 °.
- all of the internal ribs of the screen have lower edges situated in the same horizontal plane as that of the vertical peripheral wall of the frame.
- the outer edges of the V-shaped side surfaces of the intermediate part project above the horizontal central surface of the beam.
- the front part of the spatula is shaped like a bow.
- Figure 1 is a perspective view from above of the snowshoe according to the invention
- Figure 2 shows a bottom perspective view of the snowshoe according to Figure 1
- FIG. 3 represents a profile view of the racket according to FIG. 1
- Figure 4 is a plan view of Figure 3
- Figures 5-8 are respective sectional views along lines 5-5, 6-6, 7-7, and 8-8 of Figure 4
- - Figure 9 is a cross-sectional view on an enlarged scale of the intermediate part of the racket.
- a snowshoe 10 comprises a support frame 12 produced by molding an injected plastic, and having an elongated structure that is symmetrical with respect to the longitudinal median plane.
- the frame 12 is provided with a vertical peripheral wall 14 delimiting a perforated internal surface constituting a screen 16.
- the internal surface of the screen 16 is provided with a plurality of ribs 17 conferring lift and mechanical rigidity to the racket 10 when it rests on the snow.
- the frame 12 has an intermediate portion 18 extending at the rear by a tail 20, and at the front by a rounded tip 22 and raised upwards. The width of the frame 12 gradually decreases in the longitudinal direction, from the tip 22 to the tail 20.
- the intermediate part 18 comprises a longitudinal beam 24 in inverted U endowed with a horizontal and flat central surface 26 used for mounting the hinged plate for fixing the user's shoe.
- a pair of lateral surfaces 28, 30 of support arranged in a V at an obtuse angle.
- the value of the angle can advantageously be between 120 ° and 170 °.
- the front part of the spatula 22 is shaped according to a bow, having two wings 32, 34 arranged in V symmetrically with respect to the longitudinal median plane, and connecting to the two lateral surfaces 28, 30 of support of the intermediate part 18.
- a central opening 36 is formed in the screen 16 at the front end of the beam 24, to allow the tilting of the fixing plate or the shoe around the horizontal axis of articulation, in particular when the front of the plate is equipped with a knife.
- This bow structure of the front of the screen 16 facilitates the advancement of the racket 10 in deep snow, as well as the ascent, the descent, and on flat ground.
- the rear part of the tail 20 of the screen 16 is constituted by extensions 38, 40 in V of the two lateral surfaces 28, 30 of support.
- the lift of the screen 16 is increased for a predetermined width of the racket 10,
- all of the internal ribs 17 of the screen 16 have in the intermediate part 18 lower edges 17a situated in the same horizontal plane P as that 14a of the peripheral wall 14 vertical of the frame 12.
- the outer edges of the surfaces side 28, 30 in V of the intermediate part 18 are substantially projecting above the surface, central 26 horizontal of the beam 24.
- the ribs 17 of the central zone of the screen 16 under the longitudinal beam 24 of support the shoe are conventionally equipped by a plurality of studs 42 improving the grip in hard snow.
- all of the internal ribs 17 of the screen 16 have lower edges 17a situated above the horizontal plane (P) passing through the vertical wall of the frame.
- the racket according to the invention can also be made of metal or carbon.
