Description

IMPROVEMENT FOR SNOWSHOE

  The present invention relates to a snowshoe and more

  particularly its shoe retainer.

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

  the snow for their daily necessities.

  Currently, snowshoes are rather used by sportsmen who go for hikes and walks, or even competitions. But athletes, although practicing for their pleasure, are more and more demanding for the equipment they use, and it is true that

  the products currently sold are not entirely satisfactory.

  In fact, in most cases, the retention of the shoe is not sufficient, which causes inconvenience during progression. In addition, all the shoe retention devices are inconvenient to implement for the user who is often clumsy in his

manipulations.

  The present invention proposes to solve the drawbacks of known devices by proposing a device which combines simplicity,

  convenience, security and reliability.

  Thus, the snowshoe according to the invention is of the type comprising a shoe retaining device of the type comprising a plate carrying front retaining means and rear retaining means, and is characterized in that said rear retaining means are arranged sliding on said plate and are connected to at least one of the elements of said front retaining means by traction means so that the tension and the locking of said front retaining means cause said means to move forward

rear restraint.

  according to an additional characteristic, the front retaining means are formed in part by fixed elements integral with the front end of the plate and in part by at least one movable element while the rear retaining means comprise a movable rear part in sliding on the plate, said movable element being

  connected to the movable rear part by the traction means.

  According to another characteristic, the movable element is a cover pivoting about an axis on two lateral arms integral with the front end of the plate, said cover comprising two lateral pivot arms connected by a retaining wall and each comprising a hole

  passage, respectively intended to receive the traction means.

  In a preferred arrangement, the traction means consist of a strap comprising a locking loop, the middle part of which is engaged in a housing for hooking the rear part, while the two ends are engaged in the through holes of the cover. mobile, while the hanging housing is

  arranged under the movable rear part.

  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 1 shows in a perspective view the cover of

  front restraint constituting one of the elements of the front retaining means.

  Figures 12 and 13 illustrate by side views the

  operation of the device of the invention.

  Figure 14 is an alternative embodiment illustrated in perspective. The racket intended to be equipped with the device according to the present invention can, of course, be of any type and, for example, as

  this is shown in Figures 1 and 2.

  Thus, the racket designated by the general reference (1) is as illustrated in the form of a perforated plate which comprises an outer frame (2) constituted by a peripheral wall delimiting an inner zone (3) forming the screen properly. said which includes a set of transverse straps (4). Said frame has a generally elongated shape which can be raised slightly at the front to

build a front spatula (5).

  The user's shoe (6) is retained on the racket itself by a fixing constituting the retaining device according to the invention and bearing the general reference (7). According to a preferred embodiment of the invention, the retaining device (7) consists mainly of a plate fixed to the racket so as to be articulated on the frame (2) around a transverse axis (XX ') in order to be able to pivot in a manner known per se upwards as is

represented by the arrow "Fl".

  The shoe retaining device (7) (6) therefore consists of a plate (8) comprising retaining means for the shoe (6). Namely, front retaining means (9) and rear retaining means (10), said front retaining means being intended to retain the front end (11) of the shoe, while said retaining means

  rear retainer (10) are intended to retain the rear end (12).

  According to a characteristic of the invention, the rear retaining means (10) are arranged sliding on the plate (8) and are connected to the front retaining means (9) by traction means (13) so that the locking of said front retaining means (9) causes displacement forwards along F2 and against the rear of the shoe

rear retaining means (10).

  Thus the actual plate (8) carrying the retaining means is constituted by a horizontal wall (14) bordered laterally by two cylindrical guide profiles (15, 16). The front part of the plate comprising two cylindrical lateral projections (17, 18) of axis

  (XX ') and the front retaining means (9).

  The front retaining means (9) at the front stop partly consist of fixed elements integral with the front end of the plate

  and partly by a mobile element.

  Thus the fixed elements integral with the plate are constituted by two parallel side walls (19, 20) extending upwardly extended forward by two converging front walls (21a, 21b). Furthermore, the two side walls (19, 20) are connected at their respective lower end to the plate while their upper end is connected by a curved front wall (65) which comprises a central tongue (66) extending towards the 'back and up. The mobile element is itself constituted by a pivoting cover (25) pivotally retained on the two side walls (19, 20) around an axis (XlX'l). Thus said cover (25) comprises two lateral pivot arms (26, 27) connected transversely by a retaining wall (28). Each of the lateral pivot arms (26, 27) is articulated on the corresponding side wall (19, 20) about an axis, respectively (29, 30). Furthermore, each of said lateral arms comprises a passage hole (31, 32) into which is intended to be engaged a traction and retention strap (33) constituting the traction means (13) whose function will be described

thereafter.

  The rear (10) or heel retention means consist of a movable rear part (67) sliding along F2 or F3 on the plate (8), said movable rear part (67) is formed mainly by an interlocking wall ( 34) secured to a sliding rear support (35). The interlocking wall (34) is substantially vertical and comprises a rear portion (36) in cylinder portion extended laterally by two substantially parallel rear rear retaining walls (37, 38). Furthermore, the sliding rear support (35) comprises a horizontal support wall (39) for the boot and two sliding housings (40, 41), each of these being intended to

  receive the corresponding cylindrical guide profile (15, 16).

  Note that the retention of the heel of the shoe (6) in the rear cavity (42) formed by the support (35) and the interlocking wall (34) is ensured by a rear strap (43) engaged in a passer-by (44 ) integral with the rear wall (36) said belt comprising a closing latch (45). In the road position, the rear strap (43) surrounds the kick (46) of the user. There is provided under the rear support (35) a hooking member (47) for the traction means (13), that is to say for receiving the traction strap (33). The hooking member (47) disposed under the movable rear part (67) is formed, for example, by a stirrup (48) forming a hooking housing (49) in which the middle part of the strap is engaged. traction (33) whose two ends (50, 51) are engaged in the through holes

  (31, 32) corresponding to the movable cover (25).

  The traction strap (33) is therefore engaged in its central part in the latching member (47) to be engaged by its free ends by the through hole (31, 32) of the cover (25). The two ends (50, 51) being secured to the top of the retaining wall (28) by means of a locking mouth (330) as is more particularly illustrated in FIG. 3. The bringing together of the two ends (50, 51 ) causes, on the one hand, the pivoting downwards, in the hood retaining position (25) and, on the other hand, the rearward movement of the rear retaining means (10) by pulling the strap traction, the shoe being thus urged forward against the front stop and downward pressing on the plate, the heel being retained in the heel. Note that the traction strap (33) which is hung on the rear moving part (67) of the rear retaining means (10) is such that its two strands (50, 51) pass on each side of the shoe to

  join above the retaining cover (25).

  Figures 12 and 13 illustrate the operation of the device.

  Figure 12 shows the device in its open position. In this position, the rear retaining means (10) being in the retracted position while the movable retaining cover (25) of the front retaining means (9) is pivoted upward about the axis (XlX'1) according to F4, the traction strap (33) being released. In the backward position it is then possible to introduce the boot (6) between said front retaining means (9) and said rear retaining means (10) until the bottom (60) of the boot (6 ) either resting on the one hand on the surface

  (14) of the plate (8) and, on the other hand, on the support wall (39).

  It then suffices (see FIG. 13) for the user to tighten the traction strap (33). Which causes, on the one hand, the displacement forwards along (F2) of the rear retaining means (10) by traction (T) of the traction means and, on the other hand, the closure according (F5) of the hood (25)

  until it contacts the top of the front of the shoe.

  Note that the forward movement of the rear retaining means (10) urges the front end of the shoe to bear on all of the front walls of the plate (8). The user then only has to lock the strap (33) with the locking loop (330), then surround his kick (46) with the rear strap (43) in order to retain the heel of the shoe. The shoe is thus firmly retained

on the pivoting retaining plate.

  Note that the position of the pivoting axis (Xl, Xl) of the cover (25) can be adjustable and in particular adjustable in height relative to the surface (14) of the plate. It is thus possible to provide several holes (75, 75a,

  b) for the axes (29, 30) as shown in FIG. 12.

  FIG. 14 illustrates a variant according to which it is one and the same strap (130) which ensures both the function of traction member, like the strap (13) of the previous embodiment, and both the rear kick blocking function (43) replacing the rear strap (43). The single strap (130) is in this case engaged two

times in the rear loop (44).

  Of course, the invention is not limited to the embodiments described and shown by way of examples, but it includes

  also all technical equivalents and their combinations.
