FR2834905A1 - Ski or snowboard has additional side pieces fixed in edge recesses to receive boot fastenings - Google Patents

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.

IMPROVEMENT FOR SNOW SLIDING BOARD
The present invention relates to a board for gliding on snow such as a ski, a monoski, a surf, or the like. It relates more particularly to an improvement relating to a gliding board comprising a base and at least one complementary element.

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

 We already know very many models of gliding 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 comprises a sliding sole bordered by edges metal.

 Despite all the efforts made by manufacturers to satisfy customers, to date, there is no ski that perfectly combines user comfort with satisfactory behavioral characteristics in the trajectories, whatever the type of terrain, and whoever the user is.

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

 Other characteristics and advantages of the invention will emerge from the description which follows with reference to the appended drawings which are given only by way of nonlimiting examples.

 Figures 1 to 9 show a first embodiment of the invention.

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

<Desc / Clms Page number 3>

 The ski (1) is constituted by a main part which we will call body or base (2) on which are fixed at least in the area of the shoe (4) two complementary lateral elements (3a, 3b).

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

 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, coast line, 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 such as, for example, of the sandwich type, of the box type, or of the shell type, taken alone or in combination, even mixed and made up of a set of elements and components known in themselves.

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

 As for the base (2), each of the lateral complementary elements (3a, 3b) has its own configuration and structure. It has its own distribution of thickness, width and stiffness and can be of all types of construction. Thus, said complementary elements (3a, 3b) can be formed by a one-piece element made from a single material. But it can be of a completely different conception like, for example

<Desc / Clms Page number 4>

 example, formed by a succession of different materials and / or such that the material of its front part (13) is different from the material of its rear part (14).

 In the embodiment given as an example, each of the lateral complementary elements (3a, 3b) is a profile whose section decreases towards the front (AV) and towards the rear (AR), in width and in 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). Thus the base (2) comprises a left lateral clearance (5a) in which is fixed the left lateral complementary element (3a), and a right lateral clearance (5b) in which is fixed the right lateral complementary element (3b) .

 Of course, each of the lateral clearances is of complementary shape to receive the corresponding lateral complementary element.

 Note that each of the lateral clearances (5a, 5b) opens laterally outwards (EX) and upwards (HA), while it does not open downwards (BA).

 Note that the width of the clearances is variable longitudinally, to be wider in the center and decrease forwards and backwards.

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

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

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

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

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

 Thus, a given base (2) may correspond to several complementary elements of different lengths, and, for example, three complementary elements of different lengths, as illustrated in FIG. 7. Likewise, to a determined base (2) several complementary elements of different thicknesses can correspond. Note also that a given 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) characteristics of different behaviors. The different characteristics can be obtained by different thicknesses of the

<Desc / Clms Page number 6>

 complementary elements, or by a different structure, or even different materials, or even a different geometry.

 The attachment of the complementary elements (3a, 3b) to the base (2) is, of course, by embedding in the corresponding housing (5a, 5b), this connection being able to be produced, for example, by gluing, welding. This connection can be made over the entire surface of the complementary element (3) common with its housing, or over only a part of the surface such as, for example, in the front (13) and rear (14) areas.

 Of course, provision could be made for the connection of the complementary elements (3a, 3b) to the base (2) to be carried out mechanically, for example by embedding a projection in corresponding holes.

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

 Figures 8 and 9 illustrate how the ski bindings (9a, 9b) intended to hold the boot of the skier can be fixed. For this purpose, it is, for example, provided two stirrups, front (lOa) rear (lOb), on which are fixed the fasteners (9a, 9b), said stirrups being fixed on the complementary lateral elements.

 The fixings (9a, 9b) can also be fixed on the lateral complementary elements (3a, 3b) or, of course, on the base (2).

 Of course, the invention is not limited to the embodiments described and shown by way of examples, but it also includes all the technical equivalents and their combinations.
