Description

IMPROVEMENT FOR LINKING A FOOTWEAR TO A

SNOW RACKET

  The present invention relates to a snowshoe and more particularly to an improvement in the binding of the boot which

  improves performance and comfort.

  Snowshoes have been known for many years because they have been used for several centuries by the Scandinavian populations to travel on snow Until today, snowshoes were used for utility or military purposes to enable populations and the Alpine troops to move on

  the snow for their daily necessities.

  Currently, snowshoes are rather used by sportsmen who make hikes and walks, even competitions. But sportsmen, although practicing for their pleasure, are more and more demanding for the material which they use, and it is true that the products currently sold do not give complete satisfaction, and in particular during the progression on packed, hard or icy snow, as well

  than on a side course on a slope.

  Thus, according to the invention, the snowshoe comprising a sieve carrying a binding intended to receive the shoe of the user, is characterized in that said binding is connected to said sieve so as to

  ability to pivot laterally around a longitudinal axis.

  According to one of the provisions, the longitudinal axis is arranged in the general plane of symmetry of the racket, while in another

  layout, it is biased relative to it.

  According to an additional characteristic, the attachment is linked to a support articulated on the screen around the longitudinal axis, and according to a preferred arrangement, said support is a support frame whose two side walls are such that their lower edges project under the

lower surface of the racket.

  According to another characteristic, the fixing is arranged pivoting upwards relative to the support around a transverse axis, which is

  located above said longitudinal axis.

  Furthermore, and according to a preferred embodiment, the transverse axis is disposed above the upper surface of the racket,

  while the longitudinal axis is arranged below this surface.

  Other characteristics and advantages of the invention will emerge

  of the description which will follow with regard to the appended drawings which are not

  given only by way of nonlimiting examples.

  Figure 1 is a top view of the snowshoe according to the invention.

Figure 2 is a side view.

  Figure 3 is a perspective view illustrating so

  schematically the racket with its articulation system.

  Figure 4 is a side view with partial longitudinal section.

  Figure 5 is a sectional view along V-V of Figure 2, the

  snowshoe resting on a horizontal snow plane.

  Figure 6 is a view similar to that of Figure 5 showing the

  racket resting on sloping ground.

  Figures 7 and 8 are perspective views showing

  details of the attachment.

  Figures 9 and 10 illustrate two other embodiments.

  The racket designated under the general reference (1) is in the form of an openwork plate of general plane of symmetry (P) fixed under the shoe and which consists of a main frame (2), consisting of a part peripheral (3) delimiting an interior zone (4), comprising a set of internal walls supporting the binding (5) intended to retain the shoe (6) of the user Said main frame has a generally elongated shape extending at the rear by a tail (7) of reduced width, while the front is raised and substantially shaped

  pointed to form the front spatula (8).

  All of the internal walls and the main frame form a general lower support surface (9) on the snow allowing the user not to sink too far into the snow, thanks to the large bearing surface. the binding (5) intended to retain the shoe (6) is according to the invention articulated with respect to the frame (2) of the racket itself, along two axes, a first axis, called the transverse axis (XX ') and a second axis, called longitudinal axis (YY ') Advantageously, said binding bearing the general reference (5) is constituted by an articulated plate (10) comprising means for retaining the shoe, namely front means (11) and rear means (12) Thus, the front end (60) of the shoe is retained by a front stirrup (110), while its rear end (61) is, thanks to a pivoting rear stirrup (120) comprising a retaining lever (121) The plate (10) is advantageously rigid and extends longitudinally, comprising an upper bearing surface (13) for supporting the sole of the shoe. It should also be noted that the position of the rear stirrup (120) is preferably adjustable by means of a succession of holes d 'lateral hooking (15) In addition, the fine adjustment allowing a perfect adaptation to the length of the shoe, is ensured by two

  lateral nuts (16 a, 16 b) arranged on the tie rods of the rear caliper.

  According to a preferred arrangement, the transverse axis (XX ') is arranged above the longitudinal axis (YY), said transverse axis (XX') being, in the rest position, perpendicular to the plane of general symmetry (P), while said longitudinal axis (YY ') is in turn located in said plane (P) Note also that the transverse axis (XX') is also disposed slightly above the upper general plane (90) of the screen (4 ), while the longitudinal axis (YY ') is disposed slightly below said plane (90) Thus, and as can be seen more particularly in FIG. 3, the plate (10) can pivot relative to the racket proper,

  vertically along Rl and R 2 and laterally along R 3 and R 4.

  The central part of the screen (4) comprises a central hole (17) extending longitudinally and in which takes place a support frame (18) pivoting about the longitudinal axis (YY ') The central hole (17) extending towards the front (AV) through a front hole (170) allows the passage of the front of the plate (10) during its pivoting, as well as of the front end (60) of the shoe This support (18) has the general shape of a rectangular frame bounded peripherally by two vertical side walls (19, 20) and by two vertical end walls (21, 22) These last two walls (21, 22) each comprising a hole, respectively a hole front (23) and a rear hole (24) whose axes are aligned and each intended to receive a pivot axis (25, 26)

  each linked to the sieve (2) to make the longitudinal axis (YY ') together.

  Furthermore, the front end of said support frame (18) comprises two lateral projections (27, 28) extending upwards and being pierced with a hole (270, 280), intended to receive the axis (29) of the plate (10) for making together the transverse axis (XX) of pivoting up or down according to Rl, R 2 Note that advantageously, the axis (29) is disposed backwards d 'a distance (D) from the front (30) of the shoe so that the pivot axis (X') is disposed at the metatarsals and thus allow better support Furthermore, and according to a complementary characteristic, the walls lateral (19) and (20) have a height (H) sufficiently large so that the lateral lower flanges (190, 200) protrude relative to the lower general plane of support (9) of the screen (4), like this appears more particularly in FIGS. 2, 4 and 5. In addition, note that the lateral lower edges (190, 200) are also th n protrusion under the plane (Pi) defined by the flange

  lower (30) of the wall (3) of the main frame.

  It goes without saying that it would not go beyond the scope of the invention if the longitudinal axis (YY ') was disposed at an angle relative to the longitudinal plane (P) of general symmetry of the racket, as is

  shown as an example in Figure 9.

  Of course, it could be that the binding of the shoe is different from that described, and moreover, it could only be associated with the racket to be able to tilt laterally, as is

  shown schematically in Figure 10.

  Of course, the invention is not limited to the embodiments described and shown by way of examples, but it also includes all the technical equivalents and their combinations.
