Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a ski stopper, and more particularly, to a stopper that prevents skis from drifting away down a slope when the skis are removed from the skier after the safety binding has been disengaged due to a fall of the skier. Regarding.

This type of device replaces the safety belts used up to now.

Such a device consists of at least one restraining arm rotatably attached to the ski forming a six spade.

Under normal conditions, the spade is in a stop position protruding downward from the running surface of the ski, and at this time, the spade is held in this position by activation means made of an elastic member.

When the shoe contacts the binding attached to the ski, the shoe maintains the spade in an inactive position where it is above the surface of the ski.

When the binding is released, the spade moves into the active position and penetrates the snow surface somewhat, so that the ski remains immobile and can be easily retrieved by the skier.

Skis are therefore prevented from drifting down the slope, causing harm to other skiers located below, and skis are not lost.

Various types of ski stops are known in which the centerline of the spade is parallel to the plane of the upper surface of the ski, but inclined to its longitudinal centerline.

In these cleats, the spade is returned above the ski when the ski is put on.

However, this required nearly 270 degrees of movement of the spade, thereby making it impossible to use these chocks with the activation means advantageous to treadles.

In such a stop, the spade has a rotation angle of 9
It forms an angle greater than 0 degrees, and when rotated it describes a cone.

Other cleats are also known in which the center line of rotation of the spade lies in the transverse plane with respect to the ski and slopes downwardly from the outside to the inside.

In this case the spade defines a plane perpendicular to the axis of rotation and partially located above the ski when rotated.

All these known devices are not completely satisfactory.

This is because the use of simple actuation mechanisms is not possible, and the volume and height are large.

The object of the invention is to overcome the above-mentioned disadvantages and to obtain a flow stop of very simple construction by means of a special arrangement of the center line of rotation of the spade.

According to the invention, when the sole is placed on the ski, it is mounted on a pivot so as to be rotatable about a center line between an inoperative position, in which it is retracted onto the ski, and an active position, in which it protrudes from the running surface of the ski. at least one spade member pivotally mounted and actuating means for displacing the spade member from the inactive position to the activated position, the centerline of the spade member being between the longitudinal centerline of the ski and the front or rear of the ski. A ski stop is provided which slopes toward the ski.

Due to this particular arrangement of the center of rotation, i.e., that it is inclined with respect to three reference planes formed by the horizontal plane of the upper surface of the ski, the vertical plane passing through the longitudinal axis of the ski, and the vertical transverse plane, 18 defining a cone
It is possible to move the spade from its inactive position to its active position (or vice versa) with a rotation amount clearly less than 0 degrees.

The ski stop of the present invention can be easily used in conjunction with known treading devices.

Furthermore, in the inactive position the spade is clearly located above the ski and therefore does not interfere with the use of the ski.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

However, it goes without saying that the present invention is not limited thereto.

The ski stop according to the invention, the main part of which is shown schematically in FIG. 1, essentially comprises a spade member 1 which bottoms out a restraining arm that is thrust into the snow.

The spade member 1 is mounted rotatably about a centerline 3 by a pivot 3, and the shaft 3 is mounted in a bearing 4 supported by the ski.

The rotation 0 imaginary centerline 2 of the spade 1 is shown as a projection in three perpendicular planes.

That is, its projection in the horizontal plane is XX' (Fig. 2), its projection in the vertical longitudinal (in other words parallel to the ski axis) plane is YY' (Fig. 1), and its projection in the vertical transverse plane is is represented by ZZ' (Figure 3).

According to the invention, the center line 2 is the horizontal plane of the ski (projection YY
') and also with respect to the lateral vertical plane (projection xx').

The center line 2 is thus inclined downwards towards the interior of the ski and towards the rear of the ski.

According to another aspect of the invention, the spade member 1 and its pivot 3 form an angle of less than 90 degrees in all figures.

The spade 1 is shown in a non-operating position by a solid line, and in an active position by a broken line.

In the first inactive position, spade 1 extends above the ski and is approximately parallel to the upper surface of the ski, and pivot 3
The direction extends from the ski to the rear of the ski.

Preferably, the spade 1 is bent from the pivot 3.

In order to be moved into the working position, the spade 1 defines a part of a cone having a center line 2 and an apex formed by the bending point 6 of the spade 1 and the pivot 3 forming said center line.

Figures 1 to 3 show the projection ellipse of the basic circle defined by the free end of the spade 1, if the spade 1 could describe a perfect cone.

The thick line on this ellipse shows the trajectory that the free end of the spade 1 effectively forms between its activated and inactive positions.

A first practical example of the flow stopper according to the present invention will be explained with reference to FIGS. 4 and 5.

In this case the spade 1 and the pivot 3 are constituted by elastic rods or wires of considerable diameter, for example iron wires made from spring steel.

As mentioned above, the pivot 3 forming the center of rotation of the spade 1 is inclined downwardly towards the centerline and rear of the ski.

At the lower end, opposite the bending point 6 forming the apex forming the cone, the pivot is taken over by an internal longitudinal arm 7, which extends forward approximately parallel to the base of the spade 1.

In the inoperative position of FIG. 5, the front arm 7 is pressed against the upper side of the ski in the vicinity of the longitudinal axis of the ski, while the rear subate 1 is parallel to the rear from its surface at a height above the ski. It extends to

At the front end, the arm 7 is succeeded by a transverse force-directing web member 8, the end of which is bent rearward to form a section.

This member extends to the rear of the ski by an external arm 9 which is inclined towards the center line of the ski, in other words towards the internal front arm 7.

The outer arm 9 is bent outwards at its rear end to form a transverse finger member 10 housed in a guide bearing 11, in which displacement movement is prevented.

As stated above, the inner arm 7, the transverse web 8 and the outer arm 9 form a rearwardly open, elastically deformable loop.

The guide bearing 11 for the end transverse finger 1o is located forward with respect to the rotation bearing 4 of the pivot 3.

When the spade 1 is in the operating position shown in broken lines in Figures 4 and 5, the arms 7, 8 and the web 8 extend forward over the ski and form a pedal against which the heel of the shoe 12 rests when the ski is put on again. .

The spade 1 holds itself in the working position by tension due to the deformation of the rod or elastic wire that constitutes it.

Alternatively, this action may be performed by suitable activation means integrated into the bearing 4.

The pedal formed by the two arms 7.8 and the web 8 also forms a loop, the two transverse arms 7.9 of which are variable in angle, so that the loop has a variable amount due to elastic deformation. This means that energy can be stored.

Is shoe 12 a pedal? , 8 and 9, the spade 1 rotates clockwise as shown in FIG. 4-5.

At a certain moment during this rotation, the inner arm 7 is positioned above the surface of the ski, while the nib 8 and outer arm 9 are still tilted above and below the ski.

Continuing to apply pressure by the heel of the shoe 12 on the web 8 and the outer arm 9 causes the loop to deform by twisting around the center line of the inner arm 7, thus accumulating an amount of elastic force, which The force is built up upon release and facilitates the passage of spade 1 from its inactive position to its activated position.

It is possible to devise other structures for the pedals forming part of the spade 1, in order to store the amount of energy that results from the deformation of the spade 1 by bending or twisting or both.

In the variant shown in FIGS. 6 and 7, the pivot 3 of the flow stop extends forward by an internal longitudinal arm 7 and a transverse force-directing web 8. In the variant shown in FIGS.

The web 8 is the pedal on which the ski is refitted - on which the heel of the shoe 12 is placed either directly or on the front lateral pivot 1.
It is placed on a small plate 13 pivoted around 4.
Configure.

In this case, additional activation means are required to move the spade 1 from its inactive position to its activated position.

This is because the spade is free in the bearing 4 without being subject to any elastic forces.

In order to perform this activation, means as shown in FIGS. 8 and 9 are provided within the bearing 4.

This means places the piston 1 in the recess 16 in the body of the bearing 4.
5 is accommodated in the lateral direction with respect to the rotation center 3 of the spade pivot 3.

The piston 15 is a compression spring 17 provided within the housing 16.
is constantly pushed back against the lateral surface of the pivot 3.

The pivot 3 has a diametrically flat portion 3a against which the piston 15 abuts when the spade is in the operating position as shown in FIGS.

As soon as the spade 1 leaves its working position due to its displacement into the inactive position, one of the edges defining the flat 3a pushes the piston 15 against the spring 17 and automatically brings the spade 1 into the working position. The spring is compressed to cause the transition to .

This type of activation device has a rotation of spade 1 of up to 90 degrees.
Used alone when there is a degree.

This device is particularly simple and advantageous for ski locking according to the invention.

This is because spade 1 must be moved 9 degrees around axis 2 in order to move the spade from the activated position to the unactivated position (or vice versa).
This is because it only needs to be turned less than 0 degrees.

In the actual case of the present invention explained above, the rotation center line 2 of the spade
and pivot 3 is shown as being angled downwardly towards the interior and rear of the ski.

However, this is in no way limiting.

This is because a similar but opposite arrangement is possible in the sense that the ski stop is activated by the front of the shoe.

In this case, the center of rotation 2 is tilted towards the interior and front of the ski, so that the spade 1 extends to the front of the ski.

It should be noted that in the inoperative position, no part of the stop extends beyond the width of the ski, allowing for comfortable skiing.

Therefore, the above embodiments are illustrative and not restrictive, and various modifications can be made without departing from the spirit of the present invention.

For example, two spades with a single loop,
5, or by simply connecting the spades by a wire which is elastically deformed when the ski is refitted due to the convergence of their axes.
