Description

DETAILED DESCRIPTION OF THE INVENTION

[0001] The present invention relates to the area of a device for holding shoes on a gliding board for surfing on snow.
More specifically, the present invention relates to a user (surfer)
The present invention relates to a holding means that allows a bending (or tilting) movement of a leg with respect to a foot of the subject.

When performing surfing on snow, a user steers his board on a substantially straight or curved trajectory. In each case, maneuvering can be performed accurately only if the bearing of the board to the snow surface is controlled by the user.

[0003] When the track is relatively straight, the bearing can be controlled well, but when the track is curved,
Experience has shown that this control is difficult or even impossible.

In practice, the user must constantly move his torso and limbs in order to balance while maneuvering the board. Obviously, it is extremely difficult to perfectly balance balancing and maneuvering the board in a curved trajectory or during a turn or on a bumpy slope.

[0005] Actually, the operations performed to maintain the balance are:
Impedes the control of the bearings required for accurate maneuvering. In particular, when the user bends or tilts the legs in order to maintain a balance, it cannot at the same time avoid a sudden and sometimes sharp change in the degree of inclination of the board relative to the ground.

[0006] This change in inclination usually results in an abrupt change in the area of contact of the board with the ground. As a result, maneuvers are disrupted and trajectory control becomes uncertain. The reason for this is that the ground reaction to the board can be very different.

This phenomenon is particularly evident when the user needs to balance and be supported on the ground by the side of the board on his back.

In the prior art, devices have been proposed that provide some flexibility in positioning between each foot and the board.

For example, French Patent No. 2,650,752
In the case of a signal, its purpose is to provide the most comfortable and most balanced during the turning movement of the user by means of a flexible hinge connection arranged between the foot and the board. Is to be able to be in a different posture. However, the device according to French patent 2,650,752 does not allow the user to control the bearing change. In fact, the flexibility of the hinge connection does not facilitate accurate maneuvering, nor does it make it possible to correctly identify the sensory information received by the user. As a result, this device is not satisfactory in practice, and control of curved trajectories is difficult and even impossible.

[0010] DE 8902125 proposes a device for holding a shoe on a board comprising a shell hinged to a soleplate along a transverse axis. This hinge connection allows the device to be folded for transport. Removable resilient means can hold the shell in use with respect to the bottom plate. This elastic means serves to limit the bending movement of the lower leg towards the foot. As a result, the user is easily supported at the forefoot.

On the other hand, due to the flexibility of the device, the user cannot easily control the curved trajectory.
In particular, it is virtually impossible to keep the trajectory selected when balancing and at the same time controlling the ground support together with the side of the board on the back side of the user.

The present invention aims at obviating the disadvantages listed above. To this end, the present invention proposes a device for holding shoes on a gliding board,
The device includes, inter alia, a rear bearing element for securing a rear bearing of the lower leg and a sole plate for receiving the sole, which rear bearing element has a substantially transverse axis Y-
It is hinged on the bottom plate along Y '.

A feature of the present invention is that at least one elastic means is provided on the bottom plate in accordance with a hinge (joint) movement along the axis YY 'in the direction of bending of the lower leg toward the foot (ie, from back to front). The purpose is to bias the rear bearing element.

In fact, this arrangement allows the lower limb to tilt with respect to the board, so that, regardless of the trajectory of the board, the rear bearing element always remains in contact with the lower leg. As a result, the user can continuously perceive the sensory information.

According to one embodiment, the invention is characterized in that the back bearing element is a single block. This structure provides the device with lateral stiffness to the foot that is suitable for maneuvering during turns.

According to another embodiment, the invention relates to an apparatus for controlling the X-axis, wherein the back bearing element lies in a substantially longitudinal plane of the device.
A shell and an arcuate member hinged to each other along X 'are included. This structure provides the device with lateral freedom of the lower leg relative to the foot, which is suitable for implementing the correct form of the figure.

The invention also provides for the articulation (hinge) movement of the rear bearing element relative to the soleplate along the axis YY 'in the direction of extension of the lower leg relative to the foot (ie, from front to back). Is limited.

Therefore, the user can take a rigid rear support against the ground when the balance must not be changed suddenly.

A variant embodiment of the device according to the invention is:
The resilient means is a compression spring, one end of which biases the rear bearing element and the other end of which biases the bottom plate in the direction of separation.

An advantage of the present invention is that the spring can remove snow clogs.

Another variant embodiment of the invention is characterized in that the resilient means is a coil spring, one end of which is connected to the back bearing element and the other end of which is connected to the bottom plate. The variant embodiment has the advantage that it is not bulky.

The features and advantages of the present invention will be better understood from the following description, given by way of non-limiting example, with reference to the accompanying drawings, which illustrate how the invention may be practiced.
Will be better understood.

FIGS. 1a and 1b show a gliding board 1,
A pair of devices 2 for holding a user's (surfer's) shoe 3 is fixed on this board. Each holding device 2 includes a bottom plate 4 for holding the feet and a rear bearing element 5 for the user to lean against the rear edge and to receive a special support in the swivel against the slope. The holding devices 2 each
The tip of the foot is oriented substantially transverse to the board 1 such that it is close to the front longitudinal side 6 of the board 1 and the heel is close to the back longitudinal side 7.

Each holding device 2 comprises means for holding the shoes 3 on the holding device 2, represented in the form of strips 8, 9, 10; the two strips 8, 9 are at the foot. The shoe 3 is held on the soleplate 4 and one strip 10 holds the shoe 3 to the back bearing element 5 at the lower leg.

Each holding device 2 has a hinge, here represented in the form of a rivet 11, so that the rear bearing element 5 can pivot with respect to the bottom plate 4 about a substantially transverse axis YY 'of the holding device 2. It is hingedly connected to the bottom plate 4 by connecting means. The axis YY ′ is substantially transverse to the longitudinal direction of the holding device 2 extending from the toes to the heel.

According to the spirit of the invention, the elastic means urge the back bearing element 5 against the bottom plate 4 according to a rotational movement about the axis YY 'in the direction of bending of the lower leg towards the foot. This elastic means may be a compression spring 12 shown in FIGS. 1a, 1b, 2, 3 and 4.

According to various alternative embodiments, without changing the spirit of the invention, the stress applied by the elastic means may be permanent or temporary.

As shown in FIG. 4, the spring 12 is guided by a rod 13 having a cylindrical cross section. The spring 12 is supported at one end by a small dish-shaped member 14 integrally connected to the bar member 13 by any suitable means (for example, welding) 15. The spring 12 is supported on the stopper 16 via the other end,
The plug itself is fixed to the sleeve (sheath) 17 by, for example, a threaded portion 18. The plug 16 is provided with a boring portion 19 at the center thereof serving to guide the rod member (rod) 13 in the compression direction or the extension direction of the spring 12. The sleeve 17 has an end facing the stopper 16
The hole 21 of the shaft 22 extends through the drilled plate-shaped flat portion 20. The rod member 13 has an end protruding from the boring hole 19 and extends through a thick plate-like flat portion 23 in which the hole 24 of the shaft 25 is formed.

Accordingly, the rod member 13 can be guided in the sleeve 17 by the bore hole 19 of the plug 16 and can enter the sleeve 17 against the action of the spring 12.

As shown in FIGS. 1a and 1b, the sleeve 1
7 is, in effect, hinged on the rear bearing element 5 to the stop pin 26, the hole 21 of the plank 20 and the two holes (orifices) of the pedestal 27 by means of a common shaft 22.

The rod member 13 is hinged on the bottom plate 4 to the fixing pin 28, the hole 24 of the thick plate-like flat portion 23, and the two holes of the pedestal 29 by a common shaft 22.

Since the spring 12 urges the small dish-shaped member 14 and the plug 16 in a direction of separating the back plate supporting member 5 and the bottom plate 4, the spring 3 is urged in the bending direction of the shoe 3.

As shown in FIG. 4, the means for stopping the movement of the back support element 5 with respect to the bottom plate 4 in the direction of extension of the foot is realized by, for example, the cooperation of the bottom 35 of the sleeve and the end 36 of the bar member 13. When the bottom 35 and the end 36 come into contact, the spring 12 is in maximum compression.

The holding device 2 thus manufactured is
The action of the spring 12 urges the rear longitudinal side 7 towards the ground and allows the user to flex the leg quickly and easily. As a result, contact is realized between the back side surface 7 and the ground when the user turns his / her back on the slope of the land or when turning at an uneven portion of the slope. Therefore, the operation of the body and the legs performed to maintain the balance does not hinder the operation of the board 1.
