FR2677550A1 - Apparatus permitting the assembly of parallel skis - Google Patents

Abstract

The invention relates to a device making it possible to keep two skis parallel while leaving the skis the ability to pivot laterally in both directions. It consists of a front spatulate part (tip) (1), of a central strip (2) and of a rear part (3) with a tunnel (6). The skis (7) are connected to the device by means of silent blocks (5) at the front and (4) at the rear. The user keeps his feet bearing on the two skis which are kept parallel. The device according to the invention is intended for skiing.

Description

 The present invention relates to an apparatus for mounting parallel skis.

 In Patent 87.11174 the front spatula part (1) and the rear part (4) are only connected via the axes (14) and (16) at the front and the axes (13) and (15) in back.

 This device has the following drawbacks: - when the skier prepares his turn and during his execution, or when he is crossing (more or less perpendicular to the slope line) under a strong thrust, mainly from the upstream ski, he produces a deflection of the front part (1) and the rear part (4) deviation that the springs (Addition certificate 88.02910) alone cannot avoid.

- the springs (14) and (16) at the front and the springs (13) and (15) at the rear are not strong enough to prevent the front spatula part (1) and the rear part (4) from get up in heavy and deep snow.

This phenomenon causes an accumulation of snow at the front hinge as well as at the rear hinge producing blocking at the front and braking at the rear. In addition, the skier, who must have a rear support on the device in difficult snow, does not feel this support enough because the rear part is too flexible and gets up.

- the lack of material between the skis (2) and (3) causes an annoying accumulation of snow.

 The device according to the invention overcomes these drawbacks.

 The accompanying drawings illustrate the invention.

 Figure 1 shows in perspective the device according to the invention.

 Figure 2 shows a front view of the device.

 Figure 3 shows a top view of the device.

 In reference to these drawings, the device comprises a front spatulated part (1) which is extended in its central part by a strip of material (2) which is received between the skis (7) and this up to the rear part (3). with which it is united.

 The dimensions of the front spatula part (1) can vary in length and width between 21cm and 31cm.

 The dimensions of the central band (2) can vary in width between 5cm and 12cm and in length between 80cm and 180cm depending on the length of the skis used.

 The dimensions of the rear part (3) can vary in length and in width between 21cm and 31cm.

 The thickness of the device corresponds to the thickness of traditional skis; approximately 0.5cm at the front and rear and 1.5cm in the central part.

 Fn as regards the rear part (3), this has in its central part and over its entire length a tunnel (6) whose width corresponds to the width of the central strip (2) and whose height can vary between 2cm and 5cm. The central strip (2) is joined to the rear part (3) at the top of the tunnel (6) and joins the front spatulated part (1) with a slight slope distributed over the entire length of the central strip (2 ).

 The front spatulated part (1), the central strip (2) and the rear part (3) and its tunnel (6) are one and the same piece.

 The two front edges (8) of the rear part (3), on either side of the central tunnel (6) are spatulated and they extend to overlap 2cm to 5cm in height and 3cm to 8cm in length au- above the rear of the two skis (7), this to allow the fixing of the silent-blocks (4).

 The skis (7) are connected to the front spatula part (1) by means of silent-blocks (5).

 These silent-blocks are fixed on the tips of each ski (7) and on the front tip part (1) on each side of the central strip (2).

 The skis (7) are connected to the rear part (3) by means of silentblocks (4). These silent-blocks are fixed on the rear of each ski and on the two legs (8) of the front edges, which overlap the skis (7), of the rear part (3) on both sides. other of the tunnel (6).

 During assembly, the distance between the silent-blocks (5) of the front spatula part (1) and the distance between the silent-blocks (4) of the rear part (3) can be adjusted according to the desire for use. (wider skis, greater distance between skis). These silent blocks must always be mounted in the axis of the skis and have the same spacing at the front as at the rear so that the skis (7) always work in parallel.

If the device is manufactured in one go either by molding or injection in traditional materials for the manufacture of skis (synthetic fibers of "polyester", "kevlar", "carbon" or polyurethane foam) the length of the central strip (2) is determined before manufacture based on the skis used.

 The dimensions recommended for the device are - for the front spatula part (1) width 26cm length 25cm.

- for the central strip (2) the width is 8cm at the start of the spatula part (1) and 9cm at the entrance to the upper part of the tunnel (6) from the rear part (3). The length of the central part (2) depends on the length of the skis used.

- for the rear part (3) the width at the front is 26cm and 27cm at the rear, the length is 25cm.

- for the tunnel (6) the width is 9cm and the length is the same as that of the rear part (3) 25cm.

- the height of the tunnel (6) is 2cm at the entrance and 3cm at the exit.

 -the center distance between the silent-blocks (5) of the front spatula part (1) is 18cm and the center distance between the silent-blocks (4) of the rear part (3) is also 18cm .

 The device according to the invention is particularly intended for the practice of parallel skiing with the feet resting on the two skis.
