Abstract

The ski or snowboard (1) has a main part, such as a body or base (2), fitted with additional side pieces (3a, 3b) set in edge recesses that have surfaces pointing upwards (HA) and outwards (EX), but not downwards (BA). The width and depth of the recesses vary along their length, being greatest in the middle of the ski and reducing towards the front and rear ends. The additional side pieces are of similarly varying section; they project slightly above the edges of the recesses, and have a length equivalent to 30 - 60 per cent of the length of the base. They can incorporate transverse flexible or shock absorbing elements.

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, on which is fixed, at least one element complementary.

The practice of sliding sports is gaining more and more followers and has terribly evolved in recent years with more and more practitioners more demanding in terms of product quality. This is, for example, the case snow sports.

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 with satisfactory characteristics of behavior in trajectories, whatever the type of terrain, and whatever whatever the user.

The present invention provides versatile skis consisting a base and at least one additional element, the cooperation of shapes, dimensions and structure, gives the whole skiing its necessary characteristics, both comfort and ski driving.

Thus, according to the invention, the snow gliding board such as a ski, monoski or surf, is of the type which includes a part main, known as body or base, to which is fixed, at least in the area of the skate, at least one complementary element, and is characterized in that that the complementary element (s) are retained in a corresponding lateral clearance, which opens laterally towards outside and upwards, while it does not open downwards.

According to an additional characteristic, the base has its own distribution of thickness, sideline, width and stiffness, while according to the preferred embodiment, it includes a rib longitudinal bordered by two lateral clearances, the width of which is less than the width of the bottom.

According to other additional characteristics, the width and / or the height of the clearances is variable longitudinally, to be more important in the center of the ski, and decrease forwards and / or backwards.

According to another characteristic, the element (s) complementary side are formed by elongated profiles, which are advantageously of evolutive cross section in its dimensions and / or in its forms.

Add that the width and / or the height of the side elements is variable longitudinally, to be more important in the center of the ski, and decrease forwards and / or backwards.

In the preferred mode, note that the length of the elements additional side is between 30% and 60% of the length of the base, while their height is slightly greater than the height of the corresponding clearance.

According to an additional characteristic, to a base determined corresponds to a set of several complementary elements different sides, by their length, and / or their width, and / or their thickness, by their mechanical characteristics, by their structure, or their geometry.

Note that there are two stirrups, a front stirrup and a stirrup rear, on which are fixed the fasteners intended to retain the shoe of the user.

According to a variant, the two stirrups are connected to each other to form a single stirrup.

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.

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

The ski (1) consists of a main part which we call body or base (2) on which are fixed at least in the skate area (4) at least one additional element, and depending on the mode preferred execution, two complementary lateral elements (3a, 3b).

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 and constitutions.

Thus, the elongated beam constituting the base (2) can be of all types of designs such as those known to date as, for example, sandwich type, box type, or shell type, or still of the type combining shell and lateral fields, taken alone or in combination, even mixed and made up of a set of elements and components known in themselves.

Figure 10 'is a schematic cross-sectional view of a type ski associating a hull, and side fields.

The two lateral complementary elements (3a, 3b) are formed by elongated profiles, the cross section of which in a section transverse is advantageously scalable, in its dimensions and / or in its forms.

As for the base (2), each of the complementary elements side (3a, 3b) has its own configuration and structure. He has his own distribution of thickness, width and stiffness and can be of all types of constructions. Thus, said complementary elements (3a, 3b) can be formed by a one-piece element made in one and the same material. But it can be of a completely different conception like, for example example, formed by a profile having substantially the shape of a tube comprising an external wall made for example of material composite, the central part of which is empty or filled with a material of filling, like synthetic foam.

In the exemplary embodiment, each of complementary lateral elements (3a, 3b) is a profile whose cross-section decreases forwards (AV) and backwards (AR), in width and thickness.

According to a characteristic of the invention, the base (2) comprises lateral clearances (5a, 5b) in each of which is fixed one of the corresponding lateral complementary elements (3a, 3b). So the base (2) includes a left lateral clearance (5a) in which is fixed the left lateral complementary element (3a), and a lateral clearance right (5b) in which is fixed the right side complementary element (3b).

Of course, each of the lateral clearances is shaped partially complementary to receive the complementary element lateral (3a, 3b) corresponding.

Note that each of the lateral clearances (5a, 5b) opens laterally outward (EX) and upward (HA), while not not lead down (BA).

Note that the width (L1) of the clearances is advantageously longitudinally variable, to be wider in the center of the ski, and decrease forward (AV) and / or backward (AR).

Similarly, the height (H1) of the clearances (5a, 5b) is advantageously variable longitudinally, to be more important in the center of the ski, and decrease forwards (AV) and / or backwards (AR).

According to a preferred mode, the height (H2) of the profile of each of the lateral complementary elements (3a, 3b) is slightly greater than the height (H1) of the corresponding clearance (5a, 5b).

Furthermore, the width (L2) of the complementary elements (3a, 3b) is advantageously variable longitudinally, to be wider at center of the ski, and decrease towards the front (AV) and / or towards the rear (AR), while their height (H2) is also advantageously variable longitudinally, to be more important in the center of the ski, and decrease forward (AV) and / or back (AR).

By way of example, it will be noted that the length (L3) of the elements additional lateral (3a, 3b) can be between 30% and 60% of the length (L4) of the base (2). So the length (L3) of the elements complementary can have, for example, a length between 50 and 100 centimeters.

The two lateral complementary elements (3a, 3b) have advantageously the same length, but may have lengths different.

The shape of the cross section of each of the elements can be as shown, but may be square, round, rectangular Or other. Note also that the shape of the section can be scalable and vary longitudinally.

According to an additional characteristic, a base (2) can match a set of several lateral complementary elements (3a, 3b- 3'a, 3'b - 3 "a, 3" b).

Thus, a given base (2) can correspond several complementary elements of different lengths (L3, L'3, L "3), and, for example, three complementary elements of lengths different, as shown in Figure 7. Likewise, at a base determined (2) may correspond to several complementary elements of different thicknesses. Note also that at a specific base (2) may also correspond, several complementary elements of different mechanical characteristics, intended to give the ski (1) constituted by the base (2) and its complementary elements (3a, 3b) of characteristics of different behaviors. The different characteristics can be obtained by different thicknesses of complementary elements, or by a different structure, or even different materials, or even a different geometry.

The fixing of the complementary elements (3a, 3b) on the base (2) is, of course, by positioning and fixing in the housing corresponding (5a, 5b), this connection being able to be carried out, for example, by bonding, welding. This connection (9) can be carried out over the entire surface of the complementary element (3) common with its housing, like this is illustrated in Figure 8, or this connection (9a, 9b) can be made only on only part of the surface like, for example, in the areas of front (13) and rear (14), as shown in Figure 9.

Of course, one could foresee that the connection of the elements complementary (3a, 3b) on the base (2) is made mechanically such as, for example, by embedding a projection (15) in holes correspondents (16), as shown in FIG. 10.

It will be noted that the thickness of the complementary elements (3a, 3b) can be constant or variable.

Figures 11 and 12 illustrate how the ski bindings (9a, 9b) intended to retain the skier's boot. In this effect, for example, two stirrups are provided, front (10a) rear (10b), on which are fixed the fasteners (9a, 9b), said stirrups being fixed on the additional side elements. Note that the bracket can be fixed on the lateral complementary elements (3a, 3b) by any known means, bonding, screws, etc.

The fixings (9a, 9b) may not be fixed on a bracket intermediate, such as the brackets previously described, but be fixed on the lateral complementary elements (3a, 3b) or, of course, on the base (2).

Figure 13 is a view similar to Figure 12, showing a variant according to which the two stirrups (10a, 10b) are connected to each other to form a single stirrup (10).

Figures 14, 15, and 16 are perspective views showing three variant embodiments, according to which elements of deformation and damping (20a, 20'a, 20b, 20'b, 20c, 20'c, 20d, 20'd) in the additional elements (3a, 3b). These elements of deformation are made of elastic or elastomeric or viscoelastic material, such than foam, natural or synthetic rubber or other.

We understood that in the area occupied by the elements complementary lateral, that the base (2) included a rib longitudinal (11) bordered by the two lateral clearances (5a, 5b), of which the width (L5) is less than the width (L6) of the lower part (12) of said base (2). Each of the lateral clearances is therefore limited towards the plane of symmetry (P) by the longitudinal rib (11) and downwards by the lower part (12) of the base which includes the metal edges (7a 7b) and the sliding sole (6).

We will also add that the ski (1) can be such that the element left side complementary (3a) is different from the element right lateral complement (3b), by its length as already mentioned previously, but by its section, its transverse dimensions, its constructive characteristics, see its technical characteristics.

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.
