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, to which at least one element is fixed 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 a shaped beam elongated whose front end is raised to form the spatula, while the bottom surface includes a slip 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, with a vertical plane of general symmetry, is type comprising a main part, called body or base, constituted by a longitudinal rib formed by two lateral clearances which open laterally outwards and upwards, while they do not not open down, to form a lower side border, while, in each of the clearances, is fixed an element lateral complement respectively, and is characterized in that the ski height corresponding to the distance between the upper surface of the additional side elements and the lower sliding surface is variable.

According to one of the embodiments, the thickness of the border lower side of the base and the height of the elements complementary are variable.

According to an additional characteristic of the embodiment previously mentioned, the thickness of the lower side border of the base and the height of the additional elements decrease gradually from the center of the ski, forward and / or backward.

According to another embodiment, the thickness of the border lower side of the base is constant while the height of the additional elements is variable, to gradually decrease from the center of the ski forwards and / or backwards.

According to another embodiment, the thickness of the border lower side of the base is variable to gradually decrease from the center of the ski to the front and / or rear, while the height of the complementary elements is constant.

According to an additional characteristic, the height of one to less of the lateral complementary elements, is equal to or greater than the height of corresponding clearances.

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

Add that the lateral complementary element (s) are advantageously of evolutive cross section in its dimensions and / or in its forms.

According to one of the embodiments, the width of the lateral elements is variable longitudinally, to be more important in the center of the ski, and decrease forwards and / or backwards.

According to another embodiment, the length of the elements additional side is equal to or greater than 30% of the length of the base, while the height of the profile of each of the elements complementary side is slightly greater than the height of the corresponding clearance.

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.

Figures 18, 19, 20 are side views of a ski along three variants.

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 coips 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 advantageously gradually decreases from the area central (40) forward (AV) and rear (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) comprises a left lateral clearance (5a) in which is fixed the left lateral complementary element (3a), and a clearance right lateral (5b) in which the lateral complementary element is fixed right (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 at the center (40) of the ski (1), and advantageously gradually decrease, towards the front (AV) or towards the rear (AR), and advantageously towards the front (AV) and towards the rear (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 progressively decrease, towards front (AV) or rear (AR), and preferably forward (AV) and backwards (AR).

According to a preferred mode, the height (H2) of the profile of at least one lateral complementary elements (3a, 3b) is slightly higher at the height (H1) of the corresponding clearance (5a, 5b), and this, on all or part of the length of the complementary element. But, depending on the mode preferred is the height (H2) of the profile of the two complementary elements lateral (3a, 3b) which is slightly greater than the height (H1) of the corresponding clearance (5a, 5b),

Thus, the general plane (P3) of the upper surface (30) of the additional lateral elements (3a, 3b) is located above the plane (P1) of the upper surface (110) of the longitudinal rib (11).

According to another embodiment illustrated in FIGS. 17A, 17B, 17C, 17D, 17E, the height (H2) of the profile of each of the elements lateral complements (3a, 3b) is equal to the height (H1) of the corresponding clearance (5a, 5b), over the entire length of the complementary element. So the general plane (P3) of the surface upper (30) of the lateral complementary elements (3a, 3b) is located in the same general plane (P1) of the upper surface (110) of the longitudinal rib (11).

We therefore understood that the height (H2) of the profile of at least one additional lateral elements (3a, 3b), or even each of them, can be equal to or greater than the height (H1) of the clearances correspondents (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 advantageously gradually decrease, from the center (40) of the ski (1), towards the front (AV) or towards the rear (AR), while their height (H2) is also advantageously variable advantageously gradually forward (AV) and backward (AR) longitudinally to be greater in the center (40) of the ski (1), and decrease towards the front (AV) or backward (AR), preferably forward (AV) and toward rear (AR).

We will add that the height (H), namely, the thickness of the ski (1), i.e. the base (2) plus additional lateral elements (3a, 3b), is equal to the distance between the upper surface (30) of the elements lateral complements (3a, 3b) and the lower sliding surface (6). Thus, the height (H) corresponding to the thickness of the ski (1) at the level of the lateral complementary elements (3a, 3b) is equal to the height (H2) of the additional lateral elements (3a, 3b) plus the thickness (H3) of the lateral edge (20) of the base (2).

Note that the height (H) is variable to decrease advantageously progressively forward (AV) or rearward (AR), and advantageously forwards (AV) and rearwards (AR).

a- une bordure latérale (20) d'embase (2) d'épaisseur (H3) variable qui diminue progressivement du centre (40) du ski (1), vers l'avant et vers l'arrière, tandis que la hauteur (H2) des éléments complémentaires (3a, 3b) est, elle aussi, variable pour diminuer progressivement du centre du ski vers l'avant et vers l'arrière tel que cela est illustré à la figure 18.

b- une bordure latérale (20) d'embase (2) d'épaisseur (H3) constante, tandis que la hauteur (H2) des éléments complémentaires (3a, 3b) est variable pour diminuer progressivement du centre du ski vers l'avant et vers l'arrière tel que cela est illustré à la figure 19.

c- une bordure latérale (20) d'embase (2) d'épaisseur (H3) variable pour diminuer progressivement du centre du ski vers l'avant et vers l'arrière, tandis que la hauteur (H2) des éléments complémentaires (3a, 3b) est constante tel que cela est illustré à la figure 20.

This variation in height (H) can be obtained in different ways, namely:

a- a lateral border (20) of base (2) of variable thickness (H3) which gradually decreases from the center (40) of the ski (1), towards the front and towards the rear, while the height ( H2) complementary elements (3a, 3b) is also variable in order to gradually decrease from the center of the ski forwards and backwards as illustrated in FIG. 18.

b- a lateral border (20) of base (2) of constant thickness (H3), while the height (H2) of the complementary elements (3a, 3b) is variable to gradually decrease from the center of the ski towards the front and backwards as shown in Figure 19.

c- a lateral border (20) of base (2) of variable thickness (H3) for gradually decreasing from the center of the ski towards the front and towards the rear, while the height (H2) of the complementary elements (3a , 3b) is constant as shown in Figure 20.

By way of example, it will be noted that the length (L3) of the elements complementary lateral (3a, 3b) can extend over all or part of the length of the base. It can be, for example, equal to or greater than 30% of the length (L4) of the base (2), as, for example, included between 30% and 90%. Thus, the length (L3) of the complementary elements can have, for example, a length between 50 and 150 centimeters, for a ski having a length of 170 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, 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, even its technical characteristics.

It goes without saying that the variations mentioned above are advantageously progressive, but it goes without saying that variations can be carried out by successive stairs, with or without interruptions.

We will add that the upper surface (30) of one of the elements complementary (3a) is not necessarily at the same level as the upper surface (30) of the other of the complementary elements (3b).

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.
