Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an element for holding the rear of a shoe on an alpine ski.

[0002]

[Prior art]

 In a conventional manner, such an element is provided with a guide rail provided to be assembled in conjunction with the upper surface of the ski, a movable body along the guide rail, and a body for holding the body along the guide rail. It has a stud, a spring, commonly referred to as a retraction spring, housed between the stud and the body, and a jaw supported by the body, the jaw having two stable positions for holding and releasing the shoe. It is movable with respect to the elastic return force of the elastic return device.

[0003] Ski brakes, which are usually provided in most existing holding assemblies, are connected to a rear holding element.

[0004] Once the retaining element has been assembled on the ski, the rear retaining element has the main function of retaining the rear end of the boot and releasing the boot if excessive stress is applied. Another function of the retaining element is to adapt the retaining assembly to the length of the shoe. To that end, the position of the body of the element can be adjusted along the guide rails using a holding insert. Furthermore, in a conventional manner, from this position the body can be further retracted against the opposing return force, so that the body can pinch the boot and the retaining assembly can follow the deflection of the ski. .

[0005] The problem with these retaining elements lies in their configuration, in particular the mounting of the various elements, which must be as simple and functional as possible.

[0006]

[Problems to be solved by the invention]

 Thus, one of the objects of the present invention is to propose a structure of the rear holding element in which the mounting of the various elements is simplified. Another object of the present invention is to propose a structure in which the form of adjustment of the main body along the guide rail can be easily implemented.

[0007]

[Means for Solving the Problems]

 Other objects and advantages of the present invention will be described below. The holding element according to the invention is provided so as to be assembled in conjunction with the ski or the intermediate plate. The element consists of an elongated guide rail along the longitudinal direction, a body guided to slide along the guide rail, a movable jaw supported by the body, and a body for holding the body along the guide rail. The main body has a cavity below which a retraction spring for connecting the main body and the bracket is housed, and the cavity is vertically defined by a front wall and a rear wall, and the assembly is held by the main body. It is mounted so that it can be returned elastically forward at a position preset by the position of the bill.

In the holding element according to the present invention, the spring is connected to the bracket by a connecting latch lot, and the rear end of the lot has a folded portion sandwiched between the rear end of the spring and the rear wall surface of the cavity. The front end has a connecting hook provided for connection to a post and a connecting pawl directed rearward, the pawl being provided with a rearwardly folded portion of the latch lot behind the cavity. When supported on a wall surface, it is fitted into an edge located at the front of the main body, and in this latch lot position, the spring is placed in a compressed state.

[0009] According to a second feature, the folded portion of the latch lot has a concave or convex portion protruding rearward or depressed, the portion having a concave shape located on the rear wall surface of the cavity. Or cooperate with a concave-convex supplementary relief.

[0010] Thus, the subassembly formed by the body and the retraction system is particularly easy to install, and once installed, the connecting latch lock and the retraction spring protrude from their storage. It can operate without the traditional dangers.

The present invention will be more clearly understood from the following description with reference to the accompanying drawings.

[0012]

[Embodiment of the invention]

 FIG. 1 is a side view of a retaining element 1 mounted on a part 2 of a ski. A retaining element is provided so that the rear end of the boot can be released. To that end, the holding element has a jaw 4 supported by the body 3. As before, the jaw 4 is movable around the shaft 5 between two stable positions, a low position for holding the shoe and a high position for releasing. The spring 9 housed in the main body resiliently pushes back the piston against the inclination 4a located behind the jaw. It is this gradient that induces jaw movement between the two stable positions. Of course, other configurations are also possible.

[0013] The lever 6 for taking off the shoes allows the voluntary opening of the chin towards the higher position.

The body 3 is mounted so as to slide along guide rails 7 which are also provided to be assembled in conjunction with the ski along a defined longitudinal direction.

According to the embodiment shown here, a boundary wedge between the guide rail and the upper surface of the ski is inserted.

As can be seen in FIG. 2, the guide rail 7 has in its cross section a flat shape with a bottom 7 a of the guide rail 7 and two opposite return mechanisms 7 b and 7 c. At its base, the body has a lateral slide seat 12 fitted to slide in the guide rail return mechanism.

At the front, the holding element is distinguished from the main body, but includes a pedestal 14, which is an element mounted to slide along the guide rail 7 like the main body by lateral slide seats 15a and 15b. Have. The upper surface 16 of the pedestal is designed as a bearing surface for the sole.

A ski braking device 17 is mounted on the pedestal 14. In the embodiment shown, the rotary bearing 18 of the braking arm 20 is assembled to the pedestal 14. The braking arms 20 extend beyond the bearings by a branch having an operating pedal 19 at their ends.

The braking device is assembled to pedestal 14 by any suitable means. For example, the pedestal has a space 21 provided in a central portion thereof to accommodate the bearing of the braking device. Once installed, the bearing is held forward by the return mechanism 21a of the space 21 and rearward by one or several screws. As shown in FIG. 2, the bearing 18 of the braking device widely covers the upper side and the side surface of the pedestal 14. Other configurations are also conceivable.

The position of the main body along the guide rail is determined by a holding insert 22 housed in an upright hole 23 of the pedestal 14.

The deposit is a metal part formed by, for example, bending. On its underside, the insert has teeth 24 provided for fitting into the notches of a notch row 26 provided on the bottom 8 of the guide rail.

The insert is vertically movable into its upright hole 23. The insert is also returned lower by the spring 27 in the toothed position. The deposit is operated between a fitted position and an open position by a lever 28 housed in the upper portion of the pedestal 14.

For example, as shown, the lever 28 is housed in a cutout located in the upper part of the pedestal and is connected to the insert 22 by a vertically oriented stop pin 30.

Preferably, the cutout of the pedestal communicates laterally, and the lever 28 projects into this zone relative to the side edge of the pedestal so as to access the side of the pedestal.

In this way, the deposit can be very easily operated by means of a very natural movement of the hand. First, place your palm on the body of the element. Thus, the tip of the thumb is naturally placed on the tip of the lever 28. Thus, the thumb is inserted under the tip of the lever, the lever is pushed upward, the metal is removed, and the teeth are opened. Thus, the hand placed on the main body can move the main body along the guide rail toward a new position. Once this position has been reached, the insert is loosened and its teeth fit into the notches in the guide rail. As before, if the teeth are not in front of the notch, the body only needs to be moved slightly forward or backward so that the teeth fall into the nearest notch.

Advantageously, due to the presence of the shoe, the deposit is covered by the sole, so that no undesired operation can take place during the sliding.

From the position defined by the deposit, the body 3 can be further retracted against the restoring force opposite the retraction spring that returns the body so as to hit the pedestal 14.

As before, such a resilient movement causes the boot to be sandwiched between the front and rear holding elements, so that the ski can flex more freely.

Referring to FIG. 3, the retraction spring 32 is housed in a cavity 33 located in the lower portion of the body. Further, the latch lot connects the pedestal 14 and the spring 32. In particular, the latch lot 34 as shown in FIG. 5 is a metal part having an elongated shape. The latch lot extends forward by a connecting hook 36 and rearward by a fold 35, which is located in the rear of the pedestal 14 and fits into a groove 38 of corresponding shape and dimensions. The folded portion supports the rear end of the spring. Forward, the spring is supported by the front wall of cavity 33.

In addition to the connecting hook 36, the front end of the latch lot has a connecting claw 39 oriented rearward. According to the illustrated embodiment. The connecting pawl is a small protruding tooth which is cut off in the bottom of the latch lot and folded back so as to be directed obliquely towards the rear of the latch lot.

A connecting pawl is provided to cooperate with a lip 40 located in the lower part of the body, the tip of the pawl being fitted above the tip of the rim, as shown in FIG. It is.

The distance between the pawl 39 and the rear turning portion 35 is substantially equal to the distance between the front end of the edge 40 and the rear wall surface 42 of the cavity 33. In this way, when only the main body is operated outside the guide rail, the rear turning portion 35 of the latch lot is sandwiched between the tip of the spring 32 and the rear wall surface 42 of the cavity 33, and the connecting pawl 39 Is held by the rim 40. In this way, there is no danger that the spring and the latch lot will come off the rest of the body. The body with retraction spring and latch lot can be operated as a free standing sub-assembly without any special attention. It goes without saying that the spring is only slightly compressed once it is placed in the cavity, so that in the absence of stress, it is only slightly longer than the cavity.

Preferably, as shown in the attached drawings, the rear folded portion 35 of the latch lot further has a projection 45 fitted into the storage portion 44 of the rear wall surface 42. In this way, the latch lot is held in the body at the level at both ends. Of course, the relative positions of the protrusions and the housing could be reversed.

Furthermore, the pedestal 14 is extended rearward by a second edge 43 covering the edge 40. This second edge covers the leading end of the connecting latch lot. In addition, during skiing, repeated back-and-forth movements of the body can remove any snow that may accumulate in this zone.

The attachment of the spring and the latch lot to the main body is not difficult, and can be performed by utilizing the elasticity of the spring.

As shown in FIG. 6, the latching hook 36 of the latch lot, once installed in the main body, protrudes toward the front of the main body. At this time, the pedestal 14 is placed at a position where the hook 36 is fitted into the groove 38. In this way, the sliding seats of the main body and the pedestal penetrate each other into the extension. Thus, the assembly is also fitted into the guide rail. Preferably, groove 38 is provided such that the engagement of hook 36 causes a slight additional compression of retraction spring 32. In this way, when the main body is returned so as to hit the pedestal, the play between the main body and the pedestal can be eliminated.

There are other ways to first fit the body into the guide rails, then connect to the pedestal 14 and then slide the assembly to the desired position. To facilitate this operation, preferably, the lateral slides 15a, 15b of the pedestal extend only forward of the pedestal, and the pedestal is rearward, in particular in the zone of the deposit, rearward. Have no. In this way, as shown in FIG. 6, the body is located in front of the guide rail and returns the pedestal on the guide rail to connect the latch lot to the pedestal. This further raises the deposit by the teeth hitting the bottom of the guide rail. Next, the assembly is retracted in the guide rail until the insert teeth fall into the first notch of the guide rail.

The braking device is assembled to the pedestal before or after the mounting of the pedestal in the guide rail, depending on the type of assembly in which the assembling screw is provided for screwing up or down.

Once installed in the guide rail, the retaining element can be attached to the ski by any suitable means, in particular screws.

In this way, the assembly of the holding element is simplified as long as the body with the retraction spring is assembled as a self-supporting sub-assembly and the insert, which is also a self-supporting sub-assembly, is connected to the main body. Is done.

Furthermore, the deposit is placed in front of the body, not behind it. Thereby, the body has a more compact structure, the rear of which is largely released above the ski.

Of course, the present invention is only a guide and other embodiments of the present invention could be adopted without departing from the scope of the present invention.

In particular, it is also possible to configure the latch lot and the edge connecting pawl in other ways. Importantly, when only the body is operated outside the guide rails, the pushing force on the retraction spring connects the latch lot at least in front of the body.

Furthermore, the connection between the pedestal and the body could be configured in various ways. Importantly, the connection is made by fitting or engaging along the direction perpendicular to the longitudinal direction of the guide rail, so that the element does not fall apart once it is fitted in the guide rail. Is a point.
