Description

The present invention relates to a device for moving on snow,

  snowshoe type, comprising means for sitting a shoe articulated with respect to support means on snow or ice, said seat means being

  in rotation, on the one hand, along an axis transverse to said support means and, on the other hand, along a longitudinal axis with respect to said support means.

  The present invention is in the field of snow sports and mountain recreation, especially in traveling on snow, including snowshoeing.

  The invention more particularly relates to a snowshoe type snow moving device.

  A racket is known to support the weight of a person when moving on the snow, preventing it sinks. To do this, a racket generally comprises a seat for receiving the foot of a person through fastening means, said seat being secured to a tray of substantially different shape and design but which has the characteristic of increasing the support surface on the snow.

  To facilitate walking, it has been imagined to articulate the rotating seat relative to the plate through an axis placed under said seat and disposed transversely to the racket, perpendicular to the direction of travel.

  Such a racket is adapted for a displacement on most reliefs. However, when moving along a slope or across a slope, the plateau remains parallel to the ground, which is inclined, while the lower limbs, feet and legs, must remain substantially vertical so that the person maintains his balanced. This difference is compensated by the joints of the lower limbs, especially through the flexibility of the ankles and knees. But this position is very uncomfortable and tiring. It can also be dangerous, causing a fall or injury in case of imbalance.

  This drawback finds a solution in a racket of the state of the art, described in document FR 2 702 156, comprising an additional articulation under the seat along an axis of rotation that is longitudinal with respect to said plate, substantially along the axis of the symmetry of said racket.

  However, this type of racket does not offer complete satisfaction because of the precarious balance it provides to the person because the rotation is carried out under the foot of the latter, and therefore under its support.

  Another disadvantage of snowshoes of the state of the art appears ascent or descent in front of the slope. Indeed, to keep the foot substantially horizontal, it is necessary to add a wedge raising under the heel for the rise and to block the rotation of the plate relative to the seat for the descent. These operations do not necessarily happen easily depending on the case and can be bold.

  The invention aims to overcome the disadvantages of the state of the art by providing a snowshoe type of snow moving device easily allowing movement on a slope or a slope, while conferring a stable equilibrium.

  To this end, the invention relates to a device for moving on snow or ice, of the racket type, comprising means for seating a shoe articulated with respect to support means on the snow or ice, said means for seat being rotated, on the one hand, along an axis transverse to said support means and, on the other hand, along a longitudinal axis relative to said support means, characterized in that the axis of longitudinal rotation is disposed at least partly above said seating means so that said shoe is suspended.

  According to other features of the invention, it comprises fastening means before seating means adapted to receive said longitudinal axis above said seating means.

  Advantageously, the front fixing means are integral with said transverse axis.

  Preferably, the front attachment means comprise attachment means, in particular cleats.

  In addition, the device according to the invention comprises rear attachment means of the seating means adapted to receive the longitudinal axis above, at or below the seating means.

  Advantageously, the rear fixing means comprise means able to pass, on the one hand, a locking position of the rotation along the transverse axis of said seating means to, on the other hand, a position of raising of the back of the seating means.

  Preferably, the blocking and raising means are mounted in rotation on an axis orthogonal to said support means.

  In particular, the locking and raising means comprise a bearing surface of the seating means shaped so as to allow, in the raising position, the rotation of said seating means along the longitudinal axis.

  According to one embodiment, it comprises means for attaching the shoe adjustable in translation along the seating means.

  In addition, it comprises means capable of limiting the rotation along the longitudinal axis, including a stop.

  Other characteristics and advantages of the invention will emerge from the following detailed description of non-limiting embodiments of the invention, with reference to the appended figures in which: FIG. 1 represents a perspective view of the device of FIG. displacement according to the invention; - Figure 2 shows a perspective view at another angle of the displacement device; - Figure 3 shows two rear views and profile of the displacement device in position A and B; and FIG. 4 represents two side and side views of the device according to the invention in position A and C. The present invention relates to a device 1 for moving on snow, such as a racket or the like. The displacement device according to the invention is also intended for movement on ice, hard snow to frost.

  The displacement device 1 according to the invention comprises seat means 2 of a shoe. As can be seen in FIGS. 1 and 2, these seat means 2 can be in the form of a plate provided with attachment means for the boot. These are provided adjustable to fit the shoe size. To do this, the attachment means are mounted in translation along the seat means 2, for example in the form of a slider being shaped complementarily to the shape of the heel of a shoe so as to block the latter. In addition, additional fasteners may be added to hold the shoe on said platen, such as straps, ties, laces, clips, etc. The seating means 2 are hinged relative to the support means 4 on the snow or ice. According to Figures 1 and 2, these support means 4 may be in the form of a tray under and around the seating means 2 to increase the support surface on the snow. This plate may have a front portion rounded upwards, such as a spatula 5, to facilitate movement, especially by avoiding the end of the racket to penetrate or sink into the snow during movement.

  A first feature of the invention lies in the fact that the seat means 2 are rotatably mounted relative to the support means 4 along a transverse axis 6. This transverse axis is integral with means 7 for fixing the front portion. seat means 2 so that the plate pivots relative to the plate at the tip of the shoe.

  In particular, in order to improve the movement, especially on hard snow to frost or ice, the front fastening means 7 comprise means 8 of attachment. These can be in the form of crampons, partially visible in Figure 1. These spikes can be provided removable relative to said front fastening means or directly molded therein during their manufacture. Therefore, these hooking means can be made of any material, but preferably of metal or plastic. In addition, the crampons are provided protruding relative to the plate when the plate is in the rotational position relative to the plate.

  According to another characteristic of the invention, the seat means 2 are rotatably mounted along a longitudinal axis 9 with respect to said support means 4. This additional degree of freedom allows the support means 4 to pivot in order to adapt to a slope or inclination, especially when moving along a slope. Therefore, the support surface of the racket remains parallel to the ground surface while the person keeps his balance remaining substantially vertical. This position of inclination of the plate relative to the plate corresponds to the position B, visible in FIG.

  In addition, the displacement device 1 comprises means capable of limiting the rotation along the longitudinal axis, in particular a stop. This stop, particularly visible in views A and B of Figure 3, blocks the plate in its swing, limiting its rotation at a maximum angle.

  An innovative feature of the invention lies in the fact that the longitudinal axis 9 is disposed at least partly above said seat means 2 so that said shoe is suspended. Indeed, the rotation of the plate then takes place above the support of the shoe, greatly improving the balance.

  To do this, the displacement device 1 comprises means 10 for fixing the rear part of the seat means 2. These rear fixing means are capable of receiving the longitudinal axis 6 above, at or below the means. 2. Thus, the rotation of the rear of the plate can respectively be performed above or under the support of the heel of the shoe.

  Advantageously, the displacement device 1 is characterized in that the rear fixing means 10 comprise means 11 able to block the rotation of said seat means 2 along the transverse axis 6. This locking position is represented in FIG. position A of Figures 3 and 4. In addition, these locking means 11 are able to raise the rear of the seat means 2. To do this, these blocking and raising means 11 are able to move from the blocking position A at the raising position C, visible in FIGS. 3 and 4.

  In order to allow this passage from one position to another, the blocking and raising means 11 are mounted in rotation along an axis orthogonal to said support means 4. Preferably, they can be rotated by 180. The locking and raising means 11 may be substantially in the form of a half-cylinder so that in raising position C, the half-cylinder is disposed under the rear part of the seating means 2, preferably under the means rear attachment 10, thus serving as a wedge.

  This raising position C is particularly suitable when climbing on a slope or slope to increase the inclination of the boot relative to the support means 4 so that the latter remain substantially parallel to the inclined surface.

  The locking and raising means 11 comprise a bearing surface 13 of the seat means 2 shaped so as to allow, in the raising position C, the rotation of said seat means 2 along the longitudinal axis 9. To do this this surface 13 has a rounded, arcuate, concave shape, coaxial with the longitudinal axis 9, so as to allow the oscillation of the rear part of the plate.

  In this regard, the seat means 2 or the rear attachment means 10 may have a convex complementary shape to facilitate rotation.

  In particular, the displacement device 1 comprises means 14 adapted to prevent rotation along the transverse axis 6. These means 14 may be in the form of a tenon, sliding in an orifice formed in the locking and raising means 11. This tenon can then go from a retracted position to a protruding position in which it prevents rotation along the transverse axis 6 by maintaining the rear part of the seated means 2 or the rear fixing means 10.

  This locking by tenon offers the possibility of combining or not the two rotations along the transverse axis 6 and / or the longitudinal axis 9.

  In particular, the end of said tenon may comprise a notch or groove intended to cooperate with the rear end of the seat means 2 or rear fixing means 10. This notch has a width substantially equal to the thickness of the means of 2 or rear mounting means 10. Therefore, during the sliding of the tenon, the end of the seat means 2 or rear fastening means 10 fits into said notch.

  In addition, the tenon may have a second notch for locking the seat means 2 in an intermediate position of rotation along the longitudinal axis 6, between the position A and the position B. The second notch is then made obliquely relative to to the first.

  A third notch can be made symmetrically so as to allow this intermediate locking in the other direction.

  The displacement device 1 according to the invention imparts improved stability and balance to any type of relief, in particular by offering the user a pendulum position of the seat of his shoe with respect to the bearing surface of the racket.

  Of course, the invention is not limited to the examples illustrated and described above which may have variants and modifications without departing from the scope of the invention.
