Description

Detailed Description of the Invention

The present invention relates to a binding element for supporting the ends of shoes on bearings on skis (in particular skis). More precisely, the invention relates to a binding element for holding the rear end of a shoe.

The invention also relates to a binding unit for holding a shoe on a ski which comprises such binding elements.

Numerous binding units already exist. In most cases, these units include a front binding element and a rear binding element. Each binding element has a shoe-holding jaw carried on the body. In the case of the front binding element, the body is generally connected integrally with the ski. The body of the rear binding element is movable in the longitudinal direction of the ski along a pedestal or slide guide, and a spring, commonly referred to as a "return spring", pushes the stopper to elastically move the body rearward. Resist. The stopper, which is typically a bolt or screw that cooperates with the slide guide, determines the nominal position of the body. This nominal position is changed to match the binding element to the length of the shoe or to correct the return force that the return spring exerts on the body when the shoe is laid down.

The rear binding element also includes a support plate for receiving the rear end of the sole. This support plate is usually attached to the main body or the slide guide.

Recently, there has been a search for improved operability of skis on snow and damping or attenuating vibrations or shocks to the skis, resulting in skier comfort.

Published French patent application No. 2 680697 describes a device which is mounted on both front and rear binding elements. This device modifies the natural distribution of the ski with respect to the snow, depending on the bearing stress exerted by the skier on his ski. The device comprises a pressing member connected to the pedestal of the front binding element and a movable sensor on which the rear end of the shoe rides. This sensor captures the bearing stress of the shoe and transmits it to the pressing member. The sensor comprises a front extension of a slide guide which is adapted to move about a transverse axis local to its rear portion. In addition, a spring (more generally an elastic means) is interposed between the slide guide and the ski. This measure damps the vibrations passing between the ski and the shoe and contributes to the comfort of the skier.

According to the improvement described in French patent application No. 2687325, the stiffening member is removable and it is the restoring energy of the ski brake that pushes it back upwards.

According to another refinement described in WO 94/02220, an elastic cartridge is arranged at the connection between the pressing member and the front pedestal. This cartridge forms a kind of valve to prevent damage to the device when the ski is severely and greatly bent.

This kind of structure gives good results. However, considering that the device always exerts a mechanical action on the ski, this structure requires improvement, and
Not suitable for all snow types. The same applies to the damping function of the sensor part on which the shoe sole rides.

It is an object of the present invention to improve the conditions under which a device of this type works, as well as the damping conditions of a movable sensor on which a part of the sole rides.

Another object of the invention is to optimize the compromise between the damping function of the shoe part and the accuracy of skiing in response to snow conditions.

Another object is to propose a structure that is easy to manufacture.

These objects are achieved by the binding element defined in the first claim.

The movable bolts allow the various functions and damping conditions of the rear binding element to be easily selected and thus the damping conditions to be selected according to the snow conditions or the type of ski used.

In the case of mechanical devices, the bolt advantageously acts on the connecting means connecting the movable sensor to the pressing member. In such a situation, the entire device is blocked.

According to another embodiment of the invention, the front and rear binding elements are independent and only one of them is buffered. Bolts can adapt the damping conditions of the binding element to snow conditions.

According to a further embodiment, the front and rear binding elements are independent and both are buffered.

Other objects and advantages of the present invention will become apparent upon reading the following description and the accompanying drawings, which form a part thereof.

FIG. 1 shows a fastening unit, most of which is known from French patent application No. 9308913 (not yet published as of the filing date of the present patent) filed in the name of the present applicant. 1 shows a central part of an alpine ski with a binding element 3 and a rear binding element 4.

The binding unit is attached to the central part of the ski 1. The binding unit consists of a front element 3 and a rear element 4 of suitable type. Front element is pedestal 13
The main body is attached to the pedestal, and the pedestal itself is raised by the substrate 14. This unit may be attached to the ski by any suitable means (such as a screw). The pedestal extends rearward through the substrate 7 on which the shoe sole rests.

The rear binding element comprises a jaw 13 carried on a body 16. The body is movably mounted along a pedestal 17 that fits the slide guide.

The slide guide is a support plate 30 on which the shoe sole rests.
It extends forward through.

The slide guide 17 is connected to the ski by a pedestal 18 integral with the ski. This slide guide is inserted into the rear rim of the substrate 18 and is attached to the mounting guides 28 located at the rear of the slide guide.
Substrate 1 centered on the transverse horizontal axis embodied by
It is movable with respect to 8.

The substrate 18 is adapted to enable the rotational movement of the slide guide about the virtual axis. This movement has an amplitude limited by the mounting hardware 28 which is closed down at the bottom of the substrate and up at the side edges of the slide guide and at the top of the slide guide.

The slide guide is preferably maintained in a high position in a supported state with respect to the mounting hardware 28 by means of a block 32 made of an elastically compressible material. This block may be of a cushioning or viscoelastic material.

As described above, the slide guide 18 and the support plate 30 can elastically swing downward in a limited amplitude range by compressing the block 32.

The front portion of the slide guide is supported on a substantially horizontal arm 34 of a swing member 35 hinged about a shaft 36 carried by the base plate 18.

This rocking member has a support surface 41 provided in the front for cooperating with a support surface 53 having a connecting plate 45 in the rear portion. This connecting plate 45 is connected to the substrate 14 in front of it by a hinged connection or by a cartridge which can be elastically compressed by itself. Such an elastic cartridge is disclosed, for example, in International Application No. WO 94 /
It is known from the specification No. 02220 and will not be described in detail here.

The connecting plate 45 is pulled back upward by a pulling arm 58 which is operated by a spring 60.
The lifting arm is attached to the substrate 18 and
Two braking arms 10 so as to form a ski braking device 9.
Extending through.

The rear part of the connecting plate 45 is the contact surface 5 for the sole of the shoe.
Becomes 6. When the shoe is inserted into the binding element, the connecting plate is pulled down to the low position until the contact surface 56 reaches the location of the sensor 30.

The length of the connecting plate 45 is determined so that the bearing surface 53 cooperates with the surface 41 of the rocking member in the low position. The change in the bearing stress of the shoe with respect to the sensor 30 is changed by the rocking member 35, the connecting plate 45, and in some cases the connecting plate 45.
Is transmitted to the front substrate 14 via an elastic cartridge that connects the substrate 14 to the substrate 14. Therefore, these external forces are transmitted to the ski, altering the pressure distribution of the ski against snow.

The connecting plate 45 is preferably manufactured by combining the two parts 48 and 49 with each other using some suitable means (eg bolts). These two parts are slidable with respect to each other, which makes it possible to adjust the total length of the connecting plate.

In addition, the fastener unit shown in each drawing is
It has a movable bolt for stopping the vertical movement of the slide guide 17.

The bolt has an active central portion 46.
As can be seen in FIGS. 2 and 3, this central part
The block 3 that can be deformed with the swing member 35 on the bottom of the substrate
It slides between the two, and from the rear to the front under the horizontal branch portion 34 of the swinging member 35 until it comes to rest around the shaft 36 of this swinging member. There is.

The width of the active central portion 46 is approximately equal to the width of the rocker member. The thickness of this active center portion is designed to fix the horizontal branch portion 34 of the rocking member 30, while the slide guide is at a higher position and is supported by the mounting hardware 28.

It is preferable that the active central portion be slightly chamfered forward so that the active central portion can easily enter under the swing member.

The active central portion is at the position shown in FIG. 2 (that is, the position at which the active portion is disengaged from the swing member 35).
And a position shown in FIG. 3 (that is, a position where the rocking member 35 enters below), the movement is performed from the front to the rear.

The active center is driven by any suitable means (eg, by two lateral pressing members 47a and 47b accessible from both sides of the substrate 18). In the embodiment shown, the pressing member is connected to the active central part by a sheet metal. The sheet metal penetrates the side wall of the substrate at the location of the longitudinal opening provided for this purpose. The pressing member can be moved forward or backward by being sandwiched between the fingers of the hand.

The device described above functions as follows. In the rear position of the bolt shown in FIG. 2, the insert is inactive and the stress captured by the sensor 30 is transferred to the substrate 14 as previously described.

At the front position of the bolt (insertion) shown in FIG. 3, the swinging member 35 is blocked at a position corresponding to the high position 18 of the slide guide. The sensor itself does not move. At this time, the connecting plate 45 acts as a static stiffening plate that increases the rigidity of the ski. When this connecting plate is connected to the front substrate by means of an elastic cartridge, the cartridge serves to damp the curvature of the ski. That is, when the ski bends, the cartridge receives an external force. Furthermore, if the cartridge is adjustable, the stiffening effect of the connecting plate on the ski can be adjusted by adjusting the cartridge. The cartridge, in the locking position,
If the length of the connecting plate 45 exactly matches the distance between the front substrate 14 and the swinging member 35, the connecting plate 4 along the bearing surface 41 will be described.
This is advantageous as it facilitates the insertion of five.

It is also advantageous to block the rocker member itself with an insert (bolt). Because it allows the movement of the moving parts of the device to be maximally fixed,
Therefore, uncontrollable movements that cause premature wear and reliability problems are prevented. In addition, rattling of the rocking member that may occur when the ski is bent is also prevented.

Furthermore, the insert is located near the bearing plate of the shoe. Therefore, the insert efficiently fixes the slide guide in the base plate, and enables direct and accurate connection between the base plate and the ski, regardless of the external force in the vertical direction or the laterally inclined external force of the shoe. To do.

With respect to this embodiment of the invention, the types of connections between the front binding elements and the rear binding elements are not limited to this, and also other coupling methods (that is, couplings which have a different effect on the ski). It goes without saying that the method) is also applicable.

According to a variant of the invention shown in FIG. 5, the rear binding element 64 is of the same type as the binding element 4 previously described. The body of this element is slidably mounted along a slide guide 65 guided inside a base plate 66 integral with the ski. The movement of this slide guide is substantially vertical, and this movement applies a compressive external force to the block 67 made of a compressible elastic material. The movement of the slide guide is limited above by, for example, a stopper formed by an attachment hardware 68 of the substrate 66, which is bent above the slide guide.

The slide guide is a support plate 69 on which the shoe sole rests.
It extends forward through.

The binding element 64 is to be assembled to any suitable type of front binding element. However, unlike the previously mentioned device, there is no connection between the front and rear binding elements in this case.

Furthermore, the slide guide can be fixed to the substrate by means of an insert (bolt). This money is shown in FIG. The insert has an active central part 72 and two lateral pressing members 73a, 73b.

The width of the active center 72 is close to the width of the slide guides in this area. The height of this active center is such that it fills the vertical space between the slide guide and the bottom (or ski) of the base plate, while the slide guide is supported upwards on the mounting hardware 68. Is in a state.

The pressing members 73a and 73b are connected to the active center by, for example, a thin metal plate. This thin metal plate penetrates the side wall of the substrate at the opening 75.

The position and length of the opening 75 are such that the active central portion is the position shown in FIG. 6 (that is, the position where the active central portion 72 is out of the slide guide) and the position shown in FIG. The target central portion is inserted under the slide guide and can be moved together with the pressing member between a position where the slide guide is immovable with respect to the mounting hardware 68).

If desired, it is desirable to take some suitable means to display these positions with hard points that avoid uncontrolled movement of the insert.

FIG. 9 shows a modification of the insert. According to this variant, the active central part of the insert is formed by a member 80 extending forwards through a flat section steel 81. The shaped steel plate 82 is attached to the lower surface of the substrate 66.
Get on. The plate 82 has a central cutout 83,
Within this cut-out portion, the area of the shaped steel 81 that is deformed downwards comes and goes.

The shaped steel has a diametrically flat half-moon shaped opening 85 in its front part. This diameter is oriented in the direction of movement of the insert.

The flat button 86 in the shape of a screw head is
This button 8 together with the eccentric rib portion 87 provided on the lower surface
It cooperates with the half-moon shaped opening 85 for advancing or retracting the active part 80 every six half revolutions.
The body of the button is retained in the opening 88. This opening is at the location of the reinforcing crosspiece 89 where the bearing plate 69 is attached to the base plate 66 at its front part. The button has a screw groove on its upper surface, and this groove is accessible from above the base plate in front of the support plate 69. As can be seen from FIG. 9, the horizontal member 89 also has a hollow portion, and the shaped steel 81 and the plate 82 are housed in this hollow portion.

FIG. 10 shows another embodiment variant for the front binding element. The illustrated fastener element 90 is of any suitable type. The binding element comprises a base 9 hinged about a transverse axis 92 to a base plate 93 integral with the ski.
Mounted on 1. The pedestal 91 carries a shoe support plate 95 at the rear.

The pedestal can swing about the shaft 92, and an external compression force is applied to the elastically compressible block located between the pedestal and the ski. In addition, the stopper limits the upward movement of the pedestal. This stopper is formed, for example, by a side mounting hardware 98 of the substrate which is folded over the pedestal.

As in the case described above, the insert can block the rocking movement of the pedestal. The insert has an active part 99 which can be inserted under the shoe 97 of the pedestal located at the bottom of the pedestal. When viewed from the side, the insert has a pressing member 100 accessible from the outside, and the pressing member can move the insert.

Naturally, this variant embodiment can be combined with the embodiment of FIG. in this case,
The skier may choose to cushion for both binding elements, or for either one, or neither.

The fact that the cushioning of one and / or the other of the binding elements can thus be voluntarily deactivated means that the binding unit is required for snow conditions, such as hard or soft snow, and especially for comfort. Alternatively, it is considered that the suitability can be improved in accordance with the skier's desire for accuracy and high performance.

The invention is not limited to the embodiments described above, but also encompasses other embodiments, variants and equivalents as defined in the claims.
