Description

The present invention relates to a board for gliding on snow such as a ski, a monoski, a surf, or other. It concerns more particularly an improvement relating to a gliding board comprising a base and an additional element intended to receive the user's shoe retaining attachment.

The practice of sliding sports is gaining more and more followers and has evolved in recent years with more and more demanding practitioners as for the quality of the products. This is, for example, the case of sports slides on snow.

We already know many models of boards and in particular of skis which consist of an elongated beam whose front end is raised to form the tip, while the lower surface includes a sliding sole bordered by metal edges.

Despite all the efforts made by the manufacturers to satisfy customers, to date, there is no ski that perfectly combines the comfort of use and satisfactory characteristics of behavior in trajectories, whatever the type of terrain, and whatever whatever the user. Some attempts have been made as, for example, by the constructions disclosed by the French patents 2,670,392 and 2,675,391. The plaintiff, by his ski disclosed by the French patent 2,726,193, has already proposed a ski construction according to which it is planned a body on which is fixed a platform. However, despite the enormous progress that this construction brings, we realized that improvements are still possible.

The present invention provides versatile skis consisting a base and an additional element whose cooperation gives to the whole ski its necessary characteristics, as well as comfort than ski driving.

Thus, the snow gliding board according to the invention is of the type which has a main part, called body or base, which comprises at least in the skate area, on its upper surface, an element longitudinal complement intended to receive, the fixing (s) of retaining the user's shoe, said base having the shape of a elongated beam with a sliding sole, the end of which front is raised to form a spatula, the complementary element longitudinal in the form of an elongated plate laterally limited by a left side border and a right side border, the element additional comprising, moreover, a front part connected to a rear part by a middle part, and being characterized in that one at least side edges of the complementary element is supported lateral, by at least its middle part on a lateral stop cushioning in elastically deformable material.

According to one embodiment, the lateral damping stop is fixed on the upper surface of the base.

According to another embodiment, the lateral stop damping includes a damping element, sandwiched between the corresponding side border of the complementary element, and a lateral retaining projection secured to the base. So the element cushioning of the lateral cushioning stop can be integral of the lateral retaining projection, or be integral with the lateral edge of the complementary element.

According to a preferred embodiment, at least one of the borders side of the complementary element includes a hollow profile constituting, in the middle part of said complementary element, a smaller area, said hollow profile being intended to cooperate with the side cushioning of complementary shape.

According to an additional characteristic, the side border internal is in lateral support on the lateral damping stop which is arranged on the internal side of the ski.

According to another characteristic of the preferred mode, the front part of the complementary element consists of two longitudinal arms front extending from the middle part forward, while the part rear of the complementary element consists of two arms rear longitudinal extending from the middle part towards the rear.

According to another additional characteristic, the element is attached to the base on its upper surface thanks to fastening means, while the front part and the rear part of the complementary element are each fixed by fixing means to the base, ensuring relative lateral movement blocking between said element and the base, and a release of the relative longitudinal displacement, while the central part of the complementary element is fixed to the base by fixing means ensuring a locking in translation longitudinal of the complementary element with respect to the base and allowing a relative transverse movement of said element relative to said base.

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 as non-limiting examples.

Figure 12 is a top view of a ski according to a variant of realization of the complementary element.

The ski with the general reference (1) is a set of shapes elongated, having a median vertical longitudinal plane (P) of symmetry general, the front of which is raised to form the spatula (8).

The ski (1) consists of a main part which we call body or base (2) on the upper surface (17) of which is fixed at least in the area of the shoe (4) an additional element (3) intended to receive or the retaining attachment (27a, 27b) of the boot the user.

The base (2) is the element in contact with the snow and has the form of an elongated beam having on its lower surface a sole of sliding (6) bordered laterally by lateral edges (7a, 7b) metal.

The base (2) is an elongated beam whose front end is raised to form the tip (8) of the ski. This base (2) has its own distribution of thickness, coastline, width and stiffness and can be of all types of structures, geometries and constitutions.

Thus, the elongated beam constituting the base (2) can be of all types of structures such as those known to date such as, for example, sandwich type, box type, or even mixed and made up of set of elements and components known in themselves.

The complementary element (3) has the form of an elongated plate comprising two side edges (9a, 9b) extending between one end front (10) and a rear end (11).

The width (T1) of the complementary element (3), namely, the width (T1) measured between its lateral edges (9a, 9b) is less or equal to the width (T2) of the base (2) at the location of the measurement. According to one characteristic of the preferred embodiment of the invention, the complementary element (3) is such that at least one of its lateral borders (9a and / or 9b) comprises a hollow profile (12) so that said element complementary (3) includes a front part (13) connected to a part rear (14) by a middle part (16) comprising a zone of lesser width (15). It will be noted that the length (L1) of the complementary element (3) is less than the length (L2) of the base (2). For example, we note that the length (L1) of the complementary element (3) can be between 30% and 70% of the length (L2) of the base (2). So the length (L1) of the complementary element can have, for example, a length between 50 and 120 centimeters.

According to the preferred embodiment of the invention, it is the border internal lateral (9a) which includes the hollow profile (12), intended for cooperate with the internal damping stop, the internal side edge being for a right ski arranged on the left side, and for a left ski of the right side.

As for the base (2), the complementary element (3) has its own configuration and structure. It has its own thickness distribution, in width and stiffness and can be of all types of construction. So, said complementary element (3) can be a one-piece element made of one and the same material. But, it can be of a completely different conception as, for example, such that the front part (13) is different in its material and / or its design of the rear part (14), or as variant of Figure 11.

According to the preferred embodiment of the invention, the lateral retention of the middle part (16) of the complementary element (3) is produced by pressing on the lateral damping stop (5). According to this embodiment, the lateral damping stop (5) consists of an element damping (50) integral with a lateral retaining projection (18) fixed to the base (2). This lateral retaining projection (18) is arranged at the level of the hollow profile (12) of the complementary element (3). It is set at the base by any appropriate means such as screws or by gluing, or even welding or whatever. In addition, it includes an external wall substantially flat and an advantageously curved internal wall, covered with a layer of cushioning material, elastically deformable constituting the damping element (50) which, in cooperation together with the projection, constitutes the internal damping stop (5). We understand that the form cooperation between the lateral damping stop (5) and the hollow profile (12) which are of complementary shapes, also allows longitudinal retention of the complementary element.

According to the embodiment shown in Figures 1 to 10, the part front (13) of the complementary element (3) is constituted by two arms longitudinal front (13a, 13b) extending from the middle part (16) towards the front (10). Similarly, the rear part (14) of the complementary element (3) consists of two rear longitudinal arms (14a, 14b) extending from the middle part (16) towards the rear (11).

Thus, the front part (13) comprises an internal front arm (13a) and an outer front arm (13b) which extends parallel to the front arm external and separated from the latter by a front longitudinal space (19). Of likewise, the rear part (14) comprises an internal rear arm (14a) and a external rear arm (14b) which extends parallel to the external rear arm and separated from the latter by a rear longitudinal space (20).

The complementary element (3) is fixed to the base on its surface superior thanks to fixing means, which can be of any kind, but which, according to the embodiment given by way of example, are constituted by fixing screws. So depending on the mode of execution preferred, the front part (13) and the rear part of the element complementary (3) are each fixed by means of fixing to the base, ensuring a block in relative lateral movement between said element and the base, and a release of the relative longitudinal displacement. Furthermore, the central part (16) of the complementary element (3) is fixed to the base by fixing means ensuring a blocking in translation longitudinal of the complementary element with respect to the base and allowing a relative transverse movement of said element relative to said base.

Thus, the front part (13) of the complementary element is fixed to the base with two fixing screws, a left front screw (21a) and a screw front right (21b), each screw passing through an oblong hole corresponding, extending longitudinally, respectively a hole left oblong (22a) and a right oblong hole (22b). Similarly, the part rear (14) of the complementary element is fixed to the base by two screws a left rear screw (23a) and a right front screw (23b), each of the screws passing through a corresponding oblong hole, extending longitudinally, respectively a left oblong hole (24a) and a hole oblong right (24b).

Furthermore, the central part (16) of the complementary element (3) is fixed to the base, for example, by two screws (25a, 25b) passing through each a corresponding oblong hole (26a, 26b) extending transversely. The screws (25a, 25b) can be positioned in the middle the corresponding oblong hole (26a, 26b), to allow movement lateral on either side of the screws (25a, 25b) of the central part (16). But these screws could be in contact with one end of the oblong holes (26a, 26b) to allow lateral movement only on one side, and more precisely on the side of the lateral support (5).

Figure 6 is a top view showing a variant according to which the complementary element (3 ') and, in particular, its middle part (16), and more particularly its lateral hollow profile (12), is in lateral support by its two lateral edges, on a stop lateral damping (5). Thus, the base (2) comprises two stops lateral damping, one on the internal side and one on the external side. Well understood, the ski could be such that the complementary element (3) is not lateral support on a damping stopper than on its external side.

According to the embodiment illustrated in Figures 1 to 6 and 8 and 8a, the damping stop (5) consists of a damping element (50) integral with a lateral retaining projection (18) fixed to the base (2), but it could, of course, be otherwise. The damping stop (5) could thus be a single piece made of an elastic material deformable, fixed to the base as illustrated in FIGS. 7 and 7a.

Note also that the lateral retaining projection (18) which, according to the embodiment described above, is an independent part of the base on which it is fixed, could be an integral part of the base, as illustrated in Figures 8 and 8a; protrusion against which the damping element (50) would be fixed, for example, by gluing, welding or whatever.

Figure 9 is a view similar to Figure 3 illustrating a variant according to which the damping element (50) is linked to the complementary element (3) being, for example, glued to the border side of the lateral hollow profile (12) produced in the middle part, while that the lateral retaining projection (18) is linked to or is a base (2) integral part.

According to the embodiments illustrated in Figures 1 to 9, the element complementary is in abutment against the lateral damping stop by at least its middle part. Thus, the lateral damping stop is located at the middle part (16) of the complementary element (3), to cooperate with the hollow profile (12) located there, but the lateral damping projection could extend forward and / or toward the rear, to extend beyond the zone of the hollow profile (12), and also retain laterally by damping the lateral border (9a, 9b) of the front part (13) and / or the side edge (9a, 9b) of the rear part (14) of said complementary element (3).

Figure 10 illustrates an example of such a variant where the side internal of the ski (1) is such that the complementary element (3) is retained laterally by a lateral damping stop (5) which extends from the central part of smaller width forwards and backwards, to laterally hold the lateral border (9a) of the part by damping front (13) and the side edge (9a) of the rear part (14) of said element complementary (3).

Figure 11 is a top view of an alternative embodiment of an additional element. According to this variant, the internal front arm (13a) and the internal rear arm (14a) are made with the middle part (16) with a first material (M1), while the outer front arm (13b) and the external rear arm (14b) are made of a second material (M2) different from the first material (M1). The said materials may, for for example, be a filled polyamide, or a thermoplastic elastomer, or any other appropriate matter.

Figure 12 is a top view of a ski according to a variant of realization of the complementary element. According to this variant, the stop lateral damping is not embedded by form cooperation in an additional element as in the embodiments described previously. In this variant, the complementary element (3) is a simple rectangular plate, whose side edges are linear, at least its border in contact with the lateral stop damping, while the damping stop is also shaped rectangular.

The lateral damping stop (5) and / or its element damping (50) are made of elastically deformable material, such as, for example, viscoelastic material and, for example, rubber, rubber elastomer, viscoelastic rubber, or any other equivalent or appropriate material. It goes without saying also that the lateral stop damping element (5) and / or its damping element (50) can be constituted by a deformable elastic blade such as, for example, metallic or made of composite material.

Of course, the invention is not limited to the modes of realization described and represented as examples, but it includes also all technical equivalents and their combinations.
