Definitions
- the present invention relates to a knife for snowshoeing intended to be mounted on a snowshoe in a removable manner. It is also relative to a snowshoe intended to be equipped with said knife.
- Snowshoes have been known for many years because they have been used for centuries by Scandinavians to move on snow. Until today, snowshoes were used for utilitarian or military purposes, to allow alpine populations and troops to travel on snow for their daily needs. Currently, snowshoes are used by sportsmen who hike and walk, or even competitions, But athletes, although practicing for their pleasure, are increasingly demanding for the equipment they use, and it is true that the products currently sold are not entirely satisfactory.
- snowshoes must combine hook and lift criteria while maintaining maximum comfort for their users.
- the combination of these criteria is of particular importance, especially in difficult conditions such as, for example, in hard or icy snow or in conditions of steep slope.
- the current rackets do not unfortunately allow to obtain sufficient grip in such conditions and make it difficult to progress their users.
- patent FR 2 769 242 has already proposed to solve the aforementioned drawbacks by means simple, reliable, safe and inexpensive.
- This patent presents an improvement for snowshoeing intended to allow the snowshoe to adapt to snow and slope conditions by hooking means, such as a knife, said means advantageously adapting in a removable manner on the racket if necessary and according to the desire of the user.
- the present invention provides another improvement for adapting the snowshoe snow conditions and further improved slope.
- the subject of the invention is a knife for snowshoes having a bottom wall with at least one zone to which at least one lug is intended to be removably fixed, the knife comprising locking means enabling it to be assembled. and detachable to the racket, characterized in that the locking means are constituted by at least one locking lug, allowing locking to the racket via at least a portion of a removable fastener forming complementary locking means, when said member is in position fixed to the bottom wall of the racket in the same attachment area as the crampon.
- the fixing member is the crampon.
- spike a spur whose tip is the area of hanging on the snow.
- the term "knife” means an elongated element forming a wall and whose blade constitutes the snow-hung zone.
- the locking according to the invention therefore does not add any piece (s) additional (s) that may (e) protrude unnecessarily and therefore affect in particular the general aesthetic appearance of the racket.
- Such a solution also makes it possible to manufacture a simpler knife with only a functional blade profile and a locking tab.
- the user can very easily and quickly, either remove the knife from the racket which can also keep the crampon as a unique means of hanging, or conversely remove the crampon of the racket which can maintain a knife as a unique means of hooking locked through the fastener in the area provided for fixing the crampon.
- the invention advantageously makes it possible to use an existing racket manufactured to receive at least one removable crampon for adding a knife by locking said crampon in a fixed position.
- Figure 1 illustrates the preferred embodiment of the knife, the crampon and the associated snowshoe.
- FIG. 1 is a perspective view from below of the racket to which two curved knives and six studs according to the invention are attached,
- Figure 2 is a perspective view from below of the racket to which are attached two other curved knives and four crampons according to another embodiment of the invention.
- Figure 3 is a bottom view of the racket to which are attached two other straight knives and six crampons according to another embodiment of the invention.
- Figure 4 is an exploded side view of Figure 1 with unassembled knives and cleats not fixed to the racket according to the invention.
- Figure 5 is a perspective view of an alternative embodiment of a knife according to the invention.
- Figure 6a is a perspective view of an alternative embodiment of a stud according to the invention.
- Figure 6b is a sectional view of another alternative embodiment of a crampon according to the invention.
- the racket designated under the general reference (1) is in the form of a perforated plate of vertical plane of general symmetry (P) fixed under the shoe and which consists of a main frame (2) consisting of a wall lower peripheral (3) delimiting an inner zone or sieve (4), comprising a set of internal walls supporting the attachment for retaining the user's shoe, the attachment for retaining the shoe not being shown here.
- P vertical plane of general symmetry
- the attachment for retaining the shoe is preferably articulated relative to the sieve (4) of the racquet itself, along a transverse axis to be pivoted vertically.
- said attachment is constituted by an articulated plate comprising retaining means for the boot, namely, front retaining means and rear retaining means.
- a knife (5) for snowshoe (1) having a lower peripheral wall (3) to which at least one clamp (6) is removably attached.
- Said knife (5) comprises locking means (50) for removably assembling and locking it to the racket (1), which consist of at least one locking lug (50) locked to the racket (1) at less in part by the crampon (6) forming complementary locking means (60), when the crampon is in position fixed to the bottom wall (3) of the racket (1).
- the tab (50) has an eyelet (500) in which the crampon (6) is housed in part.
- a portion (60) of the crampon (6) comes, in the fixed position of the crampon (6) on the racket (1), in abutment against the eyelet (500) itself abuts against the housing of the crampon (6) arranged in the bottom wall (3).
- the knife (5) further comprises at least one support tongue (51) for pressing the knife (5) against a portion (30) of the bottom wall (3) racket (1).
- the knife (5) is formed of an elongate blade (52) whose lower edge (520) is toothless in the area where the locking tab (50) is located.
- the crampon (6) forms a complementary locking means (60) which cooperates with the locking tab (50) of the knife (5) described above.
- the crampon (6) has an outer shoulder (60) forming a washer which directly locks the locking tab (50), when the crampon being in position fixed to the racket.
- the spike (6) has an inner radial groove (61) for locking the locking tab (50) of the knife (5) via a pin not shown.
- the crampon (6) is first attached to the lower part of the racket (1), for example by screwing the net (62) in a complementary net formed directly in the racket, then the locking tab (50) is disposed around the crampon (6) below its inner radial groove (61) and the pin is inserted into the radial groove (61) by spacing its two branches from one another.
- the shape and the dimensions of the pin will be chosen so as to ensure on the one hand a play-free locking between the crampon (6) and the locking lug (50) and on the other hand an insertion and removal in the internal radial groove (61) easy for the user of the racket.
- the crampon (6) has at its fixing end (62) a thread (63) to cooperate with the thread formed in the lower part of the racket in order to fix the crampon removably to the racket (1). ).
- the crampon (6) has at its attachment end (62) a thread (63) to cooperate with a screw (7) intended to pass through the sieve of the racket to fix the crampon (6) removably to the racket (1) ( Figure 4),
- the knife (5) is first installed along the bottom edge of the sieve each cleat (6) is inserted into the eyelet (500) and into the housing usually made for this purpose in the sieve and then the screws (7) are screwed inside each corresponding crampon (6).
- the crampon (6) has an external shoulder (60) forming a washer and, as removable means for fixing the crampon (6) to the racket (1), pusher system (64) with ball (640) and spring (641) implanted transversely inside the crampon (6) and which makes it possible to fix and remove the crampon (6) more easily from the racket (1).
- a lumen opening to receive the ball (641) must be made in a portion of the stud housing so that said ball (641) blocks the crampon in its housing.
- This variant allows the user to be able to remove the cleat simply by manual pushing on the ball (641) housed in a locked position in said through hole. It goes without saying that the implantation of the opening hole will be chosen so that the user has easy access to it.
- the snowshoe (1) thus comprises the locking means (5, 50, 6, 60) allowing the knife (5) to be locked in position on the racket (1) are constituted at least in part by the removable cleat (6,60) in a fixed position on the racket which cooperates with the locking lug (50) of the knife (5).
- the knife (5) comprises a side wall (53) provided with a succession of teeth (53a, 53b, 53c, 53d, 53e ...) as shown in FIGS. 1 and 2.
- the locking tab (s) (50) is (are) disposed transversely to the side wall (53).
- the teeth (53a, 53b, 53c, 53d, 53e ...) of the same side wall (53) are of different size and shape, as shown by FIG. Figures 1 and 2.
- the knives (5) shown in Figures 1 and 2 are of elongate shape with a curved profile with an alternating concave zone and convex zone that follows the profile of the lower peripheral wall (3) thanks in particular to the fact that the knife (5) is made of elastically deformable material transversely to the wall (53) and via the support tongues (51).
- the two knives (5) according to the invention may be of elongate shape but with a substantially straight profile.
- each locking tab (50) illustrated in Figures 1 to 4 has at its end an eyelet (500) which can be housed around a portion of the crampon (6), according to another embodiment illustrated in FIG.
- the end of the locking tab (50) may have a half-eyelet shape (501) whose inner profile matches that of the crampon (6).
- This alternative embodiment allows for the user of the racket (1) according to the invention to be able to separate the (s) knife (s) (5) of the racket (1) without having to completely unscrew the crampon (6) and to remove it from its slot provided for this purpose in the lower rack wall (3) (1).
- the invention allows a racquet user to easily and quickly change surface (s) hooked by locking or not the knife (s) with the (s) cleat (s) already fixed (s) on the racket and / or removing or not one or more crampons and keeping the knife locked on the racket by a fastener, for example another crampon or other means, such as a screw, housed, for example by screwing, in the housing provided for a crampon.
