Abstract

The board (2), which has a thickness between its lower (7) and upper (8) surfaces that varies in a transverse direction, has receiving zones (22, 24) for fastenings on its upper surface. The receiving zones are fitted with wedges (42, 43, 44, 45) to compensate for the variations in thickness and provide flat supporting surfaces for the fastenings. The wedges can be in pairs or in one piece or, in another variant, in the form of rectangular parallelepiped blocks let into recesses in the board surface. They can be fixed to the board by adhesive, welding or solvent, depending on the materials used.

Description

The invention relates to the field of sliding or rolling machines comprising a board.

These machines are used for the practice of sports like snowboarding or snowboarding, surfing on water or wakeboarding, skateboarding or skateboarding, or other.

A gliding or rolling machine according to the prior art comprises a board which has a length measured in a longitudinal direction between a first end and a second end, a width measured in a transverse direction between a first edge and a second edge, a height measured between a sliding or rolling face and a reception face, as well as a first and a second reception area for the feet of a user.

When driving, the impulses given by the user cause deformations of the board, in particular in bending along a transverse axis and in torsion along an axis longitudinal.

To give the board given mechanical characteristics, it is known to it give a structure such that its relief varies transversely in certain areas other as foot reception areas.

For example, it is possible to provide a central zone of the sectional board substantially triangular, the base of which is the sliding or rolling face, and the apex of which is towards the middle of the receiving face. In this area, such a structure makes it possible to increase the flexural strength along a transverse axis and reduce the torsional strength along a longitudinal axis of the board.

In the case of snowboarding, this structure makes the board easy to drive, especially on flat and hard surfaces.

Of course, other forms of section can be envisaged to give the board given characteristics. However, the reception areas of the feet have a surface relatively flat. This allows the placement of a shoe on the receiving face, whether either directly or via a base.

In the case of snowboarding, it is frequent that the base is part of a device for shoe retention. The base has a flat bearing face which bears on the face board reception in a reception area.

In all cases, the user is able to easily transmit pulses of driving with your feet to drive the board. The latter bends or twists in correlation with impulses.

Since to accommodate the feet of the user they have a surface relatively flat, the reception areas do not participate in determining the mechanical characteristics of the board, in particular with regard to the deformation in bending along a transverse axis and / or twisting along a longitudinal axis.

The object of the invention is in particular to involve the reception areas of the feet in the determination of the mechanical characteristics of the board.

For this, the invention provides a gliding or rolling machine comprising a board, the board having a length measured in a longitudinal direction between a first end and a second end, a width measured in a transverse direction between a first edge and a second edge, a height measured between a sliding face or taxiing and a receiving face, as well as a first and a second reception area for feet of a user.

The device according to the invention is characterized in that at least one of the reception areas has a relief which varies transversely, by the fact that the machine comprises at least one wedge which has a bearing face opposite to a face for receiving the wedge, the bearing face of the shim having a shape complementary, at least in part, to the receiving face the board as defined in a reception area, and by the fact that the hold is subject to the reception area.

The transverse variation of the relief of a reception area of the board gives the area of given mechanical characteristics.

The wedge, by its complementary shape to the receiving face of the board in an area home, mounts stably on the board. Consequently a shoe or the base of a fixation stably presses on the board in the reception areas, and the wedge provided by its receiving face a determined support area, preferably flat, for the shoe or the mounting base.

The use of one or more wedges has the advantage of giving freedom of design for the structure of the board, without hindering the reception of a shoe or base on the board.

Although the examples find an application for snowboarding, it should be understood that they also apply to other areas such as those mentioned above.

The first example is described below using Figures 1 to 3.

As is known in FIG. 1, a gliding apparatus 1 comprises a plate 2. The latter has a length measured in a longitudinal direction L1 between a first end 3 and a second end 4.

Plate 2 also has a width measured in a transverse direction between a first lateral edge 5 and a second lateral edge 6, as well as a height measured between a sliding face 7 and a receiving face 8.

Of course, the transverse direction is perpendicular to the longitudinal direction L1, and parallel to the sliding face 7.

As can be seen in FIG. 3, the board 2 comprises in the direction of its height, by example, a stack of a sliding layer 9, a first reinforcement 10, a core 11, a second reinforcement 12 and a protective layer 13.

Of course, other structures could be provided to make the board 1, such as than a molded plastic wrap or whatever.

Referring again to Figure 1, Plate 2 also shows, from the first end 3 to second end 4, a first end zone 20, a first line contact W1, a first intermediate zone 21, a first reception zone 22, a zone central 23, a second reception area 24, a second intermediate area 25, a second contact line W2 and a second end zone 26. Each reception zone 22, 24 is intended to respectively receive a device for retaining a foot of a user. For reasons of convenience, the devices are not shown.

There may be provided in each reception area 22, 24 a means of anchoring the detention. This anchoring means is represented in the form of a set of threaded holes 27. However, any other structure, such as a groove widened at its base, could be suitable.

According to the invention, at least one of the reception areas 22, 24 of the board 2 has a relief which varies transversely.

As can be seen in FIG. 3 for the second reception area 24, the height of the plate 2 is more important towards the middle than at the edges 5, 6. In this zone 24 the receiving face 8 is formed by two sides 35, 36, which meet towards the middle of the plate 2 to form a vertex 37.

The latter is represented as a slightly rounded edge, but it could be constituted by a sharp edge, or on the contrary by a wider band. In this case strip could be parallel to or form an angle with the sliding face 7.

Each panel 35, 36 is shown in the form of a substantially planar face, but it could have been convex, concave, or even have a relief itself such as a ripple, streaks, or any other form of recess or protrusion.

As can be seen in FIG. 1, the gliding apparatus 1 comprises a first wedge 40 disposed in the first reception area 22, and a second wedge 41 disposed in the second reception area 24.

Each wedge 40, 41 is an intermediate element between the board 2 and the shoe or a shoe retainer. This element can be in one piece or made up of several separate parts.

In this case for the first example the first wedge 40 comprises a first part 42 and a second part 43, and the second wedge 41 comprises a first part 44 and a second part 45.

As seen in Figure 3 the first part 44 of the second wedge 41 has a bearing face 46 opposite a receiving face 47, and the second part 45 of the second wedge 41 has a bearing face 48 opposite a receiving face 49.

Each bearing face 46, 48 of the second wedge 41 has a shape complementary to the receiving face 8 of the board 2, as defined in the second reception area 24.

Thus ribs 55, 56, 57 and 58, 59, 60 of the bearing faces 46, 48, of the two parts 44, 45 of the second wedge 41, are supported on the receiving face 8 of the board 2. The ends of the ribs 55, 56, 57 and 58, 59, 60 respectively constitute the surfaces bearing parts 44, 45 of the wedge 41 on the board 2. Since the sides 35, 36 are substantially flat, the ends of the ribs 55, 56, 57 and 58, 59, 60 are contained respectively in a plane. Of course, the use of ribs is not compulsory, and the bearing faces 46, 48 could have been flat.

As shown in FIG. 2 in the case of the first part 44 of the second wedge 41, the ribs on the side of the bearing face 46 give this face a honeycomb appearance. The fact of making ribs on the bearing face 46, 48 makes it possible to lighten the wedge.

Referring again to FIG. 3, each part 44, 45 of the second wedge 41 has the general shape of a corner. These parts 44, 45 are dimensioned so that the faces of reception 47, 49 of the parts 44, 45 of the wedge 41 are substantially coplanar.

Preferably the receiving faces 47, 49 of the second wedge 41 are projecting by relative to the apex 37 of the receiving face 8. This facilitates the mounting of a device for retained in the second reception area 24 of plate 2.

The parts 44, 45 are secured to the board 2 by any means. Preferably it is provided a non-removable securing means such as bonding, welding or the like. For welding the wedge 41 and the protective layer 13 of the board 2 can be the same nature, or compatible natures. Thus a localized fusion, for example by ultrasound or at using a solvent, allows the wedge to be welded to the board. The materials used can be a polyurethane-based synthetic material, acetyl butadiene styrene, or other.

Of course, it can be provided that the means for securing the wedge 41 to the board 2 either removable. It can be made by snap-fastening, with screws, any force fitting, or other.

Of course, what has been described for the second reception area 24 applies to the first reception area 22.

As can be seen in FIG. 1, the profile of the two reception areas 22, 24 of the board is of a substantially identical triangular shape. This profile gives plate 2, in the reception areas 22, 24, given mechanical characteristics. In this case the triangular profile increases the bending stiffness along a transverse axis of the board 2, and reduces torsional rigidity along a longitudinal axis of the board 2.

The use of wedges 40, 41 made it possible to give the reception areas 22, 24 these specific characteristics while allowing flat support for the foot or for the device of restraint.

In addition, the central area 23 of the board 2 also has a relief which varies transversely.

According to the first example, the relief of the central zone 23 is substantially the same as that of the reception areas 22, 24. Thus the structure of the board 2 is substantially uniform along the three reception areas 22, 24 and central 23. This makes it possible to decline specific mechanical characteristics over the entire part of the board 2 which extends from one foot to the other of the user. Again the triangular profile of the central area 23 increases the rigidity in bending and reduces torsional rigidity. The central zone 23 may possibly have a triangular profile whose section progressively evolves between the two reception areas 22, 24.

The other exemplary embodiments of the invention will be described later using the figures. 4 to 8. For convenience, only the differences from the first example are highlighted.

For the second example according to FIG. 4, a sliding device 70 comprises a board 71 and a shim 72.

Plate 71 has a relief which varies transversely, with two sides 73, 74 which are join to form a summit 75 in a reception area 76.

The wedge 72 is shown in the form of a single piece. It has a face support 77 opposite a receiving face 78.

The bearing face 77 has a shape complementary to the receiving face of the board 71 as defined in the reception area 76.

The receiving face 78 is substantially flat to accommodate a shoe or a retainer. The receiving face 78 is parallel to the plate 71, but it could be tilted and form an angle with it.

The third exemplary embodiment of the invention is presented using FIG. 5.

A sliding device 90 comprises a board 91 and a wedge 92.

Plate 91 has a relief which varies transversely in a reception area 93 between a first edge 94 and a second edge 95.

The shim 92 is shown in the form of a single piece with a bearing face 96 opposite a receiving face 97. The wedge 92 has a first raised end 98 to proximity of the first edge 94 of the board 91, as well as a second raised end 99 to proximity of the second edge 95. The statement of the ends 98, 99 gives the receiving face 97 a concave aspect in transverse direction. This shape is particularly well suited at the reception of the sole of a shoe.

Of course, it is possible to make a block in several parts, as in the first example, with raised transverse ends.

The fourth exemplary embodiment is presented using FIG. 6. A gliding device 110 includes a board 111 and a wedge 112. The board 111 has a relief which varies transversely, in a reception area 113, between a first edge 114 and a second edge 115. The receiving face 116 of the board 111 has successively, from the first edge 114 at the second edge 115, a first lateral rib 117, a central rib 118, and a second lateral rib 119. Between the ribs, the height of the board 111 is reduced. The respective vertices 120, 121 and 122 of the ribs 117, 118 and 119 are preferably included in the same plan.

The wedge 112 has a support face 125 and a receiving face 126. The face support 125 is provided for fitting onto the receiving face 116 of the board 111, and consequently has intermediate ribs 127, 128. However, it could have been provided that the bearing face of the wedge 112 is substantially flat, to press only on the vertices 120, 121, 122 of the ribs 117, 118, 119 of the board 111.

Such an architecture gives the board 111, at least in the reception area 113, a high flexural strength along a transverse axis, and high flexibility along an axis longitudinal.

The fifth embodiment of the invention is presented using FIG. 7.

A sliding device 140 comprises a board 141 and a wedge 142. The board 141 has a relief which varies transversely, in a reception area 143, between a first edge 144 and a second edge 145.

The receiving face 146 of the board 141 has only a first rib lateral 147 at the first edge 144 and a second lateral rib 148 at the second edge 145. This architecture gives board 141, at least in the area 143, great flexibility along a longitudinal axis.

The sixth exemplary embodiment of the invention is presented using FIG. 8.

A sliding device 160 comprises a board 161 which has a length measured between a first end 162 and a second end 163. a width measured between a first side edge 164 and a second side edge 165, and a height measured between a sliding face 166 and a receiving face 167.

Plate 161 notably presents a first reception area 168, a central area 169 and a second reception area 170.

In the first reception area 168, the plate 161 has a central rib 180 of the side of receiving face 167.

On each side of the rib 180, in a transverse direction, a plane 181, 182 forms the junction between the rib 180 and the lateral edge 164, 165.

A first wedge 183, comprising two parts 184, 185, is arranged so that each of the parts rests on a plan 181, 182. The parts 184, 185 of the wedge 183 are represented in the form of parallelepipedic plates. But they could have other shapes like corner shapes.

The second reception area 170 is similar to the first in terms of its structure. The wedge it receives is also in two parts.

The seventh exemplary embodiment of the invention is presented with the aid of FIG. 9.

A sliding device 190 comprises a board 191 and a wedge 192.

Plate 191 has a relief which varies transversely, with two sides 193, 194 which meet to form a trough 195 in a reception area 196.

The wedge 192 is shown in the form of a single piece. It has a face support 197 opposite a receiving face 198. The shim can protrude relative to the hollow 195, flush the edges 199, 200, or fill only part of the hollow 195.

In all cases the bearing face 197 of the wedge has a shape complementary to the receiving face 201 of the board 191 as defined in the reception area 196.

In this case the bearing face 197 of the wedge 192 has a projection whose shape is in part at least complementary to the hollow 195 of the receiving face 201 of the board 191.

The receiving face 198 is substantially flat to accommodate a shoe or a retainer. The receiving face 198 is parallel to the board 191, but it could be tilted and form an angle with it.

For all the examples the invention is made from materials and according to techniques of implementation known to those skilled in the art.

Of course, the invention is not limited to the embodiments described above, and includes all technical equivalents which may fall within the scope of the claims which will follow.

In particular the cross sections of the board can be very diverse along the board, and the shapes of the wedges can also be various.

In all cases, the support face of the wedge can be complementary to the receiving face part of the board only.

The invention makes it possible in fact to very freely evolve the cross section of the board based on the desired effects, while ensuring stable support for the feet.

Different materials may also be provided for the holds or parts of the holds.

For the first example, a first flexible wedge 40 can be provided for the first zone. 22, and a second wedge 41 harder than the first for the second zone 24. This differentiates the nature of the driving impulses for each end 3, 4 from Plate 2.

It is also possible to provide that the first parts 42, 44 of the shims towards the first lateral edge 5 of the board 2 are flexible, while the second parts 43, 45 of the shims towards the second side edge 6 of the board 2 are harder than the first. This differentiates the nature of the driving pulses on each side 5, 6 of the board 2.
