Definitions

  • the present invention relates to a snowshoe to allow easy movement in all snow conditions on various reliefs, snowy with or without load.
  • This snowshoe interests various areas such as hikes, walks, competitions, troop movements, shaking. risme.
  • the shoes are fixed flat on a sieve or flexible plate forcing the hiker to raise the legs excessively. The result is slow and painful progression. At each step, the snow on the rear part of the snowshoe is thrown into the back of the hiker, causing him inconvenience and presenting risks of cooling.
  • such a device avoids having to spread the legs excessively when using the rackets, thanks to the off-center of the frame; the device also avoids having to raise the legs excessively, thanks to the possibility of rotation of the frame around its axis of rotation.
  • the rotation of the frame relative to the racket is not limited; during descents, it often happens that the racket makes a complete rotation around the axis of rotation, causing dangerous falls.
  • the object of the present invention is in particular to avoid the drawbacks of known devices, by proposing a new form of snowshoe ensuring permanently excellent grip even on hard snow, whether uphill, downhill or overhanging.
  • the racket is provided with means for attaching a shoe permanently ensuring effective attachment of the shoe relative to the axis of rotation; the user thus retains control of the direction of his racket.
  • the means of --fixation of the shoe are adjustable, and offer the possibility of using varied and multi-size shoes, the adjustment being very fast.
  • the racket is provided with means ensuring a very good lift on snow for a given total surface of racket, without increase in weight.
  • the racket structure chosen makes it possible to produce a racket with sufficient lift by substantially reducing the total racket surface and its weight.
  • the racket is particularly suitable for use on slopes, allowing lateral penetration of the racket in the snow on the upstream side.
  • the racket has a good lagging effect without excessively braking the progression.
  • the racket while having a good grip capacity, also avoids kick phenomena.
  • the transverse axis of rotation forms a spacer opposing the bringing together of the side members of one another; a transverse intermediate spacer connects the side members below the sieve substantially below the user's heel; the screen comprises a flexible strap stretched between the side rails; a fin extends outwards the external lateral spar over its entire length and forms a sliding bearing surface; the pivoting frame comprises a base plate provided with a front stirrup and a rear heel piece intended to hold the front and rear of a shoe respectively, attachment means making it possible to secure the shoe on the frame.
  • the end members and crosspieces have a T-shaped section, the central branch of which is oriented towards the underside of the frame and has a height of between 15 and 30 mm, the height being progressively reduced in the posterior zone of the frame to define a portion of least attachment.
  • the presence of the central branch or lower rib provides excellent adhesion; associated with the flexible sieve and the posterior portion of less hooking, it does not produce any annoying phenomenon of kicking.
  • the frame has a generally oblong shape narrowing towards the rear, the side members being substantially rectilinear and forming between them an angle of between 10 and 20 degrees, the end crosspieces forming a rounded profile.
  • the external lateral fin allows the user to easily penetrate the upstream racket upwards into the snow when using it on a slope, and to slide it longitudinally, having only to lift the downstream part of the racket. .
  • the fin significantly increases the lift qualities, without increasing the weight and the total surface of the racket.
  • the racket comprises a removable strap and of adjustable length which connects the rear parts of the heel piece and the frame.
  • the strap avoids the complete rotation of the racket around the axis of rotation, and its overturning.
  • Figure 1 shows a bottom view of a left racket according to the invention.
  • a straight racket can be obtained by symmetry with respect to the median longitudinal axis A-A.
  • the racket comprises a rigid frame 1 generally planar, that is to say comprising a substantially planar part which can be raised at the front.
  • the frame is formed by an interior lateral spar 2 and an exterior lateral spar 3 secured to each other by a front end cross member 4 and a rear end cross member 5.
  • the side members 2 and 3 are substantially rectilinear, and the end cross members form a rounded profile, as shown in the figure.
  • the frame has a generally oblong shape, tapering towards the rear 6, the side members forming between them an angle of between 10 and 20 degrees.
  • the longitudinal members 2 and 3 and the cross members 4 and 5 have a T-shaped section whose central branch or rib is oriented towards the underside of the frame, and has a height of between 15 and 30 mm.
  • the central branch 7 has a progressively reduced height, to reach, in the posterior terminal zone 8, a height less than 15 mm.
  • the frame 1 is integral with a central sieve 9 forming an openwork bearing surface provided with a front opening or toe pass 10.
  • the sieve 9 comprises a flexible strap 11 passing successively through the openings of the inner side branch 12 of the side rails 2 and 3.
  • a nylon type polyamide strap welded at its two ends by ultrasound can be successfully used.
  • the strap is stretched forming N, as shown in Figure 1, with alternately a transverse branch and an oblique branch. This arrangement ensures good tension of the screen.
  • the frame 1 receives a transverse axis of rotation 14, disposed at the posterior end of the toe pass 10.
  • the two ends of the axis 14 are housed in the side rails 2 and 3.
  • the side member 3 has a housing 15 for receiving the axis 14.
  • Figure 13 shows the housing in cross section
  • Figure 14 is a top view
  • Figure 15 illustrates the method for engaging the axis in his accommodation.
  • the housing 15 is partially open upwards through an opening 16 limited by two lateral lips 17 and 18 and a transverse bevelled lip 19.
  • the lips 17 and 18 are spaced apart by a distance slightly less than the diameter of the axis 14, while the transverse lip 19 is spaced from the lip corresponding to the spar 2 by a distance slightly less than the length of the axis 14. It will be understood that the insertion of the axis 14 is done by exerting pressure on the axis, as shown by arrow 20 to elastically spread the lips 17, 18 and 19.
  • the transverse axis of rotation 14 forms a spacer opposing the bringing together of the side members of one another.
  • the axis of rotation 14 receives, in its intermediate part, a pivoting frame 21 provided with attachment means for receiving and fixing the shoe of a user.
  • the pivoting frame 21 comprises a rigid base plate 22 secured to a front stirrup 23 intended to hold the front of the sole of the shoe.
  • the rear part of the plate 22 receives a heel piece 24 adapted by means of adjustment and locking in the longitudinal position.
  • the base plate comprises, at its front part, lower housings 25 and 26 forming bearings for the passage of the axis of rotation 14.
  • the plate 22 comprises, at its rear part, upper notches 27 cooperating with the means for adjusting the position of the heel piece 24. As shown in FIGS.
  • the heel piece 24 comprises a body 28 ensuring the abutment of the heel of the shoe; two oblong cutouts 29 and 30 allow the passage of an attachment strap for fixing the shoe.
  • the body 28 comprises a base with two walls 31 and 32 between which slides the plate 22.
  • An elastic tongue 33 is cut in the upper wall 31, its end comprising a lug 34 intended to penetrate, under the effect of the elasticity of the tongue, in the notches 27 of the plate 22 for blocking the heel piece 24 in position on the plate 22.
  • a boss 35 can be provided in the upper part of the tongue 33, boss which is pushed back by the heel of the shoe and which forces the introduction of the lug 34 into the notches 27.
  • the notches 27 have an asymmetrical profile, as shown in FIG. 8, with an inclined rear face and a straight front face, allowing the advance adjustment of the lug once the shoe is in place; the retraction of the lug can only be carried out by lifting the tongue 33 by gripping the boss 35.
  • the stirrup 23 has two raised edges 36 and 37, with oblong slots for the passage of an attachment strap. The edges are folded at 90 degrees and converge to allow the position and the abutment of the shoe. The front part of the stirrup 23 is folded down to form a crampon 38, in order to increase the grip on hard snow.
  • the plate 22 is held laterally in position on the axis 14 by two tubular spacers 39 and 40 of adequate length threaded on the axis 14, as shown in Figure 1 .
  • the inner spacer 39 is slightly shorter than the external spacer 40, for shifting the armature 21 towards the internal spar 2.
  • the external lateral spar 3 is extended towards the outside, over its entire length, by a fin 41 forming a solid bearing surface.
  • the frame 1 has a T section whose width is substantially equal to the height, the thickness of the branches of the T preferably being between 3 and 6 mm.
  • the fin 41 can have the same thickness, between 3 and 6 mm, and constitutes a slightly flexible and relatively penetrating and slippery surface when the user applies the racket on its edge in the snow.
  • the fin 41 has a width preferably between 25 mm and 60 mm, and may include a stiffening rib 42.
  • the anterior part of the carrying surface of the racket is produced by protuberances 43 of the anterior end cross member 4, protuberances extending in the rearward direction and forming a carrying surface.
  • a removable and adjustable strap 44 connects the rear part 45 of the heel piece and the rear part 46 of the frame 1.
  • the strap 44 allows the shoe to move freely up to a maximum inclination fixed by the length of the strap 44, avoiding the complete reversal of the racket with respect to the shoe.
  • the frame 1 can be made from molded plastic, also comprising the spacer 13 and the protuberances 43.
