Definitions

  • the invention relates to the field of winter sports, and more specifically to that of snow-moving vehicles such as in particular snowshoes hiking on snow. It is more particularly aimed at racket architecture allowing a versatile practice of hiking.
  • a racket has a surface bearing surface very much greater than that of the sole of a shoe, and this in order to take a large support on the snow and to distribute the pressure corresponding to the weight of the user, and thus prevent the user from sinks into the snow.
  • this bearing surface has means of attachment of the user's shoe. We know many variations of making this type of racket. So very many different shapes have been proposed. It has also been proposed to open up this bearing surface to achieve weight gains. It has also been proposed to give the shoe a articulation capacity in relation to the bearing surface to facilitate walking.
  • the ski comprises on each of these edges, a set of hinges allowing the pivoting of the two lateral wings to bring them one position where they are parallel to the surface of the ski corresponding to walking in racket configuration, to a position where they are raised laterally to only use the ski function.
  • this device has multiple drawbacks, namely a apart, that the use of hinges is tricky in terms of reliability in conditions of humidity and frost encountered in the practice of hiking on snow.
  • the position raised wings, and in particular internal wings which are opposite a foot to the other poses a problem of space and impedes the progression of the user.
  • the problem which the invention therefore proposes to solve is that of facilitating the progression of the snowshoe in the descent areas, using a simple machine, ergonomic and mechanically robust.
  • the invention therefore relates to a snow-moving vehicle, of the type comprising a bearing surface intended to bear on the snow and to distribute the pressure corresponding to the weight of the user, means for securing the boot of the user with the machine, as well as an area constituting a short ski of slips.
  • the machine according to the invention is characterized in that the sliding surface of said short ski is adjacent to the bearing surface and forms an angle with said bearing surface.
  • the invention consists in giving the racket a shape specific enabling it to simultaneously provide the lift function for walking on the flat and uphill, and the sliding function downhill.
  • the passage from one configuration to another is effected by pivoting the racket corresponding to an angle of 60 to 120 ° formed between the two useful surfaces.
  • the machine is monolithic and does not undergo any configuration changes for move from one function to another.
  • the bearing surface is limited by a frame of which one of the edges constitutes the short gliding ski.
  • the characteristic frame performs both the support function of the surface bearing and sliding skate.
  • the side of the frame opposite the short gliding ski can be advantageously of a height clearly lower than that of the skate. when the racket is in the sliding position, the frame is offset from the base of the skate sliding.
  • the frame has a general shape rectangular with the front and rear ends corresponding to the short sides of the rectangle are curved.
  • one of the long sides of the rectangle serves as a ski short of gliding and the curved ends act as raised ends for this same skate.
  • the frame has two spacers connecting two opposite sides of the frame serving as support by securing the shoe to the bearing surface.
  • the spacers can be transverse and connect the side forming the ski short of sliding and the opposite side.
  • the side forming the short gliding ski has additionally a means of securing the boot to the short ski of slips.
  • the means for securing the shoe to the surface can be pivoted relative to the short gliding ski to serve as a means of securing the shoe to the gliding pad.
  • the bearing surface is formed by two front and rear frames respectively connected by a connecting element serving as sliding skate.
  • the bearing surface is broken down into two separate areas. The association of these two frames is then advantageously carried out by the gliding pad itself.
  • the bearing surface is formed of a rigid reinforcement consisting of a main beam and transverse branches, and a light structure secured to the main beam and the transverse branches rigid reinforcement.
  • Figure 1 is a top view of a machine according to a first mode of realization of the invention.
  • Figure 2 is a side view of the same element.
  • Figure 3 is a median cross section along arrows III-III of the Figure 2, shown in the on position.
  • Figure 4 is an identical section of the same racket shown in position sliding.
  • Figures 5 and 6 are summary perspective views of a pair of snowshoes according to the invention shown excessively apart, respectively in the running position and in the sliding position.
  • Figures 7 and 8 are schematic rear views of a pair of snowshoes fitted, in walking and sliding positions respectively.
  • Figures 9 and 10 are summary perspective views of a racket according to a second embodiment of the invention, shown respectively in walking and sliding position.
  • Figure 11 is a top view of another alternative embodiment.
  • the racket according to the invention has a surface load-bearing intended for walking in solidarity with a sliding shoe allowing it, like a ski, to slide on a downhill slope.
  • the racket consists of a frame (1) of generally elongated shape.
  • this frame (1) has two parallel sides (2, 4) connected by the front and rear ends (3, 5) forming arcs of a circle.
  • the lower face (6) of this frame (1) is planar except in the ends (3,5), and receives the bearing surface (7) of the racket.
  • This bearing surface (7) can be made up in a wide variety of ways, for example by an attached solid plate, or advantageously by one or more perforated plates, without this modifying the spirit of the invention.
  • this bearing surface (7) is subdivided into two fractions (8, 9) located respectively in the front and rear part of the racket.
  • one of the sides (2) of the frame (1) constitutes the gliding pad which makes it possible to progress like a skiing, on a downhill slope.
  • this side (2) has an external face (10) arranged to present a reduced coefficient of friction. It can be for example a sole in one material used to make the skis possibly bordered by metal edges (not shown).
  • the height (H2) of the side (2) forming the shoe glide is clearly greater than the height (H4) on the opposite side (4).
  • the sole (10) of the skate glide (2) forms with the bearing surface (7) a characteristic angle.
  • this angle a is between 60 and 120 °, and preferably around 100 °.
  • edge (4) it is also useful for the edge (4) to come to rest on the shoe or on the user's calf to allow a more efficient edge grip, so better grip of the gliding pad.
  • the frame (1) has two transverse spacers connecting the sides (2, 4). These spacers (20, 21) reinforce the transverse rigidity of the racket and receive a plate (15) for fixing the user's shoe.
  • these crosspieces (20, 21) can be replaced by any equivalent means, in particular a transverse plate or longitudinal (not shown).
  • the upper face (22) of the gliding pad also receives a plate (16) for fixing the ski boot.
  • the user can, in the "on” position, either have the sliding pads (10) on the outside of each of its legs (see FIG. 7), or inside (not shown), as well as in the "sliding" position, it can have the load-bearing surface (7) either inside (see Figure 8) or outside (not shown) of each of its legs.
  • the bearing surface can be separated into two zones (30, 31) respectively before and rear connected by the gliding pad (33).
  • these bearing surfaces individual (30, 31) are arranged coplanarly and in alignment with the edge (34) of the gliding pad (33).
  • the sliding surface (30, 31) can be perpendicular gliding pad (33).
  • the shape of the bearing surfaces (30, 31) can be optimized in such a way that the plumb of the gliding shoe at the level of the fixing (35) is cleared.
  • the mounting plate (35) is advantageously articulated with respect to the shoe (33) about a longitudinal axis (36) to allow the attachment of the shoe in the two positions of the racket with the same means.
  • the locking in position of the mounting plate (35) can by example be made by a retractable stop (38), sliding along the axis longitudinal of the short ski.
  • the surface load-bearing (40) is constituted by a rigid, branched frame (41) comprising a central beam (42) and transverse branches (43,44), on which is stretched a light structure (45).
  • This light structure can be produced, as already said, from multiple ways, and in particular by an openwork plate or a textile fabric, without change the spirit of the invention.
  • the short ski (46) has its surface of slides (47) almost perpendicular to the bearing surface. The short ski is connected to the bearing surface (40) by the ends (48) of certain transverse branches (43).
  • the racket according to the invention allows concomitantly ensuring walking in a flat or uphill snowfield, and progression by sliding on a snowy slope.
