FR2852856A1 - Snow shoe for walking and sliding in snow, has loop line situated on body and obstructed by cover during passage of shoe and abutments placed on cover to release loop line during changing of shoe into slide - Google Patents

Abstract

The shoe has a body divided into two parts (1,2) longitudinally sliding one on top of another to increase a supporting surface. Clamps (4) are mounted on a pivot to fixing in snow. A hollow (14) is situated on the body and is obstructed by a cover (6) during the passage of the shoe from one state to another. Abutments are placed on the cover to open the hollow during the changing of the shoe into slide.

Description

Technical area

  The invention relates to the field of winter sports, and more specifically to that of snowshoeing on snow. It concerns a racket architecture allowing a versatile practice of hiking.

  Previous technique -1O For several centuries snowshoes have been used by mountain people or the military to move on snow.

  Nowadays, snowshoes are also used for sport hikes or walks.

  d1 By way of nonlimiting example, the invention relates to a snowshoe for hiking comprising: - a body of injected plastic material equipped with a bearing surface intended to authorize walking in snow without press down, said 2o bearing surface having an imprint in the form of an enlarged sole.

  - ice spikes located under the body intended to stabilize the user on ice or hard snow.

  - A fixing plate on which the shoe is supported, said plate being mounted on a pivot about a transverse axis housed in LE-S of the bearings located on the body.

  - Solid metal points at the front of the fixing plate allowing better grip on the ascending slopes (a recess on the body is necessary in order to let its points pass).

  - a blocking block movable between an active position and an inactive position, respectively for blocking or unblocking the fixing plate.

  - a climbing wedge movable between an active position and an inactive position, respectively to raise or not raise the rear of the 3 S fixing plate.

  - a heel support bracket, arranged in a slider, the longitudinal position of which on the plate is adjustable according to the size of the shoe.

  - various means of attaching the shoe to the fixing plate.

  2 2852856 Snowshoes currently allow the user to progress on a variety of snowy terrain. However, they have the major disadvantage of not being fully adapted to the descent. 5.

  To date, the only products on the market that allow you to slide downhill and progress on flat terrain or on uphill slopes are akin to the cross-country or ski touring family.

  The invention therefore proposes to solve the problem of progression on snowshoes in the descending zones.

Description of the invention

  The present invention provides a new method which allows snowshoes to be adapted to both walking and sliding on snow.

  In order to achieve these objectives, the present invention must: - ensure a smooth, sufficient bearing surface, in order to allow sliding downhill.

  - ensure good grip when walking to avoid possible slipping by the user.

  2-5 - allow rapid passage from one state to another without the use of tools or the addition of additional parts so that they can be transformed as often as desired by the user.

  The snowshoe according to the invention is characterized in that the body 3 Q of the snowshoe is divided into two parts, the front body (1) and the rear body (2), sliding one on the other in the longitudinal direction.

  The accompanying drawings illustrate the invention by way of non-limiting example Fig 1: Cross section of the invention Fig 2: Top view of the invention Fig 3: Partial section of the locking system Fig 4: Partial longitudinal section of the system of studs Fig 5: Partial longitudinal section of the stud system Fig 6: Partial top view of the cover system Fig 7 Partial top view of the cover system Fig 8 Perspective view of the closed assembly Fig 9 Perspective view of the 'open assembly Fig 10 Perspective view of the closed assembly E; Fig 11: Perspective view of the open assembly The object of the invention is to modify the body of the snowshoe, as well as the ice spikes.

  - Q - The racket body has been divided into two parts, the front body (1) and the rear body (2). A sliding connection between the front body (1) and the rear body (2) is ensured by a V guide (fig. 1). This technology is used to increase the bearing surface in the longitudinal direction (fig. 2).

  -1 E - A handle (5) is pivotally mounted on the rear body (2). It comprises a lug (7) so as to fit into recesses (13) located on the front body (1). These recesses (13) are placed so as to allow adjustment of the bearing surface. The handle (5) can be placed in the active or inactive position, respectively for blocking or unblocking the two bodies (1) and (2) (Fig 3).

  - the handle (5) is mounted on a spring (9) to automatically return to the active position (Fig 3).

  - Cleats (4) are mounted on a pivot around the axes (8). These axes (8) are integral with the front body (1). These crampons (4) can be placed 2.5 in active or inactive position, respectively to allow a grip in the snow or find the smooth surface of the racket (Fig 4).

  - These studs (4) are mounted on springs (10) to automatically return to the inactive position. From the position of the 3o bodies (1) and (2) depends the position of the studs (4) (Fig 4 and 5).

  - A cover (6) is located in the front body (1) in order to allow the obstruction of the recess (14) of this same body (1). A sliding connection between said cover (6) and the front body (1) is ensured by means of a V-shaped guide or the like (Fig 6 and 7).

  - Stops (12) are mounted on a pivot (15) on the cover (6) or the rear body (2). These stops (12) in contact with the rear body (2) or the cover (6) release the recess (14) of the front body (1) during the modulation of the state of gliding apparatus to that of racket (Fig 6 and 7).

  - Springs or elastic (11) are placed between the cover (6) and the rear body (2) in order to automatically obstruct the recess (14) of the front body (1) during the modulation of the racket state to that of sliding equipment (Fig 6 and 7).

  - The springs or elastic bands (11) are also used when modulating the state of the gliding apparatus to that of the racket, because they allow the bodies (1) and (2) to be automatically grouped in the longitudinal direction (FIG. 6 and 7).

  Functioning of the invention Transition from the racket state to that of sliding device (fig 8 to 1)> 0 The user exerts a pressure on the handle (5) in order to release the two bodies (1) and ( 2). The user can now increase the bearing surface by acting on the front body (1). The studs (4) are automatically placed in the inactive position in order to obtain a smooth surface. The cover (6) automatically obstructs the recess of the front body (1). The two bodies (1) and (2) are locked automatically when the lug (7) fits into the recess (13) of the front body (1).

  Transition from the sliding gear state to that of raMuette (fig 8 to 11) The user exerts pressure on the handle (5) in order to release the sliding connection between the bodies (1) and (2). The springs or elastic (11) automatically group the two bodies. The cleats (4) are automatically placed in the active position in order to obtain a grip in the snow. ú 5 The cover (6) automatically releases the recess (14) from the front body (1) thanks to the stop (12). The blocking is done automatically when the lug (7) fits into the recess (13) of the front body (1).
