    Heel for ski binding, binding and corresponding ski Technical field of the invention
    The present invention relates to a heel for ski binding, a ski binding comprising such a heel, and a ski equipped with such a binding. It relates more particularly to such a binding, which allows the user to progress, either in alpine mode or in hiking mode.
    State of the art
    Traditionally a ski binding comprises a front stop, intended to cooperate with the front end of a shoe, and a rear heel, intended to cooperate with the heel of this shoe. Two main modes of use of a ski binding can be distinguished, depending on whether the boot has a certain freedom of movement with respect to this binding. Thus, in said alpine mode, the shoe is secured to both the abutment and the heel, so that it is substantially immobilized relative to this attachment. In contrast, in so-called hiking or Nordic mode, the shoe is mounted on the front stop with a degree of freedom in rotation along a transverse axis, while the heel of this shoe is free with respect to this heel.
    The present invention is more particularly, but not exclusively, intended for skiers who wish to switch from locked heel mode to unlocked heel mode and vice versa without having to completely remove the boot. This invention will be very useful during the practice of ski touring on areas of moderate relief and having repeated changes of ascent and descent, but also to ski professionals, including trackers. In their day-to-day work, they are forced to progress along the tracks and then stop on a regular basis to perform various tasks. If these trackers use alpine skis, they must periodically carry out operations of heaving and then donning, especially in the case where they have to go up sections of tracks.
    It is therefore conceivable that, in this spirit, a telemark fixation is well suited. The tracker can then, both down the slope safely, while proceeding in a convenient way to stops or even ascent of slope. Nevertheless, in some cases, it is recommended, even necessary, that the shoe is held firmly at the heel. Examples include the carrying of heavy loads, or the transport of the wounded. It is furthermore conceivable that it is advantageous to be able to switch from alpine mode to nordic mode quickly and conveniently, in particular without having to take off.
    Fixations have been developed, which have a heel that can be locked and unlocked on the shoe, while avoiding the operations of heaving and shoeing. These include the products developed respectively under the reference ONYX® by the company Genuine Guide Gear, and under the reference VIPEC® by the company DIAMIR. These heels are equipped with a movable assembly in rotation, which comprises pins that can penetrate into the grooves of the shoe. In the advanced position of these pins, they immobilize the shoe while in their retracted position, the shoe is free relative to the heel.
    Moving the movable assembly can be achieved by means of a rear lever, capable of actuating the heel. If the user wishes to lock the shoe, namely to move the pins forward, it pivots the lever upwards. To retract the pawns and, therefore, unlock the shoe, it is to push down the aforementioned lever. These actions can be implemented with a ski pole, without having to take off.
    These known solutions, however, have certain disadvantages. Indeed, it has been found in practice that the aforementioned mobile assemblies are subject to frequent blockages, in particular due to the presence of ice. In addition, the actuation of the control lever is not completely instantaneous for the user. In particular, the pivoting of the lever upwards is achieved through the handle of the stick, which involves additional manipulations, including removing the strap of the stick.
    The problem that the present invention seeks to solve is therefore to achieve a heel that can ensure locking and unlocking the shoe without heaving, while reducing unwanted jamming phenomena encountered in the prior art. The invention also aims to provide such a heel, which is lightweight and compact. It also aims to provide such a heel, which can be implemented particularly quickly and intuitively.
    Objects of the invention
    According to the invention, the problem is solved by a heel for ski binding, intended for fixing a ski boot, said heel comprising - a plate comprising fixing means on the ski, - a body mounted on the plate - A locking member, comprising locking elements of the boot, this locking member being mounted movably relative to the body between an advanced locking position, in which the locking elements cooperate with the boot, and a retracted position of release, - a locking member of the locking member movable between an active locking position in which it immobilizes the locking member relative to the body, and an inactive unlocking position in which it allows the movement of the locking member relative to the body, the locking member comprising an actuating zone suitable for passing said locking member from its position of locking towards its unlocking position.
    The heel piece of the invention may comprise all or some of the following features, insofar as they are technically compatible: the actuating zone is a support zone, able to cooperate with an elongated object, in particular a point of contact; a ski pole. - The locking member comprises biasing means, including elastic, adapted to return to its locking position. - The heel comprises means for limiting the stroke of the locking member in at least one direction and, preferably, in two opposite directions. - The means for limiting the stroke of the locking member comprises two opposite edges of a flat part of the locking member, adapted to abut against a stop member of the locking member. - The locking member comprises a pin or a mortise, adapted to cooperate with a mortise or tenon provided (e) on the locking member. - In its advanced blocking position, the locking member defines, with the walls facing the body, an insertion space of said elongated object. - The body has a notch having a bottom and flared walls, and the locking member has an end intended to be wedged against the bottom of the notch, and an intermediate portion adapted to tilt between the walls of the notch, during the passage of the locking member between its respectively locked and unlocked positions. - The body is secured at least in translation of the plate. - The heel further comprises an intermediate shaft integral or intended to be secured to the plate, the body being pivotally mounted on the barrel. - There is provided means for controlling the pivoting of the body on the barrel. - The locking member has a U-shape, the free ends of its wings forming said locking elements. - The locking member is movable in at least one slide of the body and has a single degree of freedom in translation relative to this body, according to the main direction of the slides. The invention also relates to a ski binding, comprising a front stop and a rear heel, this heel being in accordance with that described above. Finally, the subject of the invention is a ski comprising an attachment conforming to that described above.
    It is the merit of the Claimant to have identified that the disadvantages of ONYX® and VIPEC® fasteners are mainly related to the structure of their mobile locking assembly. Indeed, in the prior art, this mobile assembly is composed of a large number of parts, so that it is relatively bulky and has a substantial mass. In particular, this mobile assembly is caused to move in the immediate vicinity of the ski surface, where substantial accumulations of snow can be formed. In this way, this mobile assembly is subject to the jamming phenomena mentioned above.
    On the contrary, the invention provides for moving a reduced number of mechanical parts, since only the mechanical elements locking the shoe are moved. Moreover, the invention makes it possible to reduce the total number of mechanical elements constituting the heel piece. Finally, the implementation of the heel according to the invention is simple and fast. It will be noted in particular that, unlike the fasteners of the prior art, the locking and unlocking can be done through the tip of the stick, therefore without having to turn it or remove the strap.

    detailed description
    In this description, the terms "forward", "rear", "front", "behind", "forward" and "backward" refer to the direction of skiing in a normal use situation.
    The heel according to the invention, which is designated as a whole by the reference 1, belongs to a ski binding. The latter comprises, in addition to the heel of the invention, a not shown front retaining element, which is known as such. It may advantageously be the front retention element belonging to the "Dynafit®" fastener, which comprises two conical lugs which cooperate with hollow and conical inserts, situated laterally at the front of the sole of the boot.
    The heel 1 essentially comprises: - a mounting plate 10 on a ski - a shaft 20 mounted on the plate - a body 30 mounted to rotate on the shaft - a locking member 40 provided with a locking pin 50, mounted on the body - and a locking member 60, also mounted on the body.
    The plate 10, which is of generally rectangular shape, has a substantially flat bottom surface, intended to rest on the upper surface of a ski not shown. For attachment to the ski, this plate has several orifices 12, for the passage of fasteners not shown, of any suitable type. This plate is hollowed with a median notch 13, ensuring the establishment of the barrel 20. At its rear end, the plate is provided with an opening 14, for the passage of a threaded rod 15, which allows the setting of the axial position of the heel according to the shoe size. This rod 15 can cooperate with a nut 16, for the attachment of the barrel. On one side of the nut, there is further provided a washer 16 'while on the other side of this nut, there is provided a spacer 17 and a spring 17'. It should be noted that this attachment of the barrel is adjustable, namely that the barrel may have different positions along the notch 13. This allows different shoe sizes to be adapted to the same attachment, as explained above. Finally, in the vicinity of this rear end, the plate has a hollow stud 18 forming a lever zone for the end of a ski pole.
    The barrel 20, of generally cylindrical shape, comprises a lower flange 21 slidable along the walls of the plate, to facilitate the positioning of the barrel relative to the notch. This barrel 20 is first pierced with a smooth axial hole 22, intended to allow the free sliding of the aforementioned threaded rod 15, namely without driving the barrel. It is furthermore hollowed out with a transverse bore 23, which receives a tension spring 24, at the ends of which are placed two balls 25. This makes it possible to control the pivoting of the body 30 with respect to the barrel 20, as will be detailed in this document. following. In its upper part, this barrel is dug with a groove 26, extending on a portion of a circle on the periphery of this barrel. This groove 26 cooperates with an axis 27, whose function will be described below. Finally, the upper end of the barrel comprises another peripheral groove for receiving a seal 28 (see Figure 6).
    The body 30 is made in the form of a roughly cylindrical cap intended to cooperate with the above-mentioned barrel 20. One of the side walls of this body is first hollowed out with a bore (not shown) intended to receive the barrel. 27. In operation, this axis 27 can move along the groove 26, which ensures the mutual rotational movement of the barrel 20 and the body 30. On the other hand, this axis prevents any substantial movement of the body 30 by relative to the barrel, according to a vertical translation, which ensures a so-called "anti-flight" function of the body 30 relative to the barrel. This body further comprises, at its upper end, two longitudinal rails 32, namely that they extend from back to front. Each of them opens at the same time on the two frontal faces of the body, as well as on one of its lateral faces.
    On one 30 'of the side walls of the body, there is provided a ramp 33 communicating with the corresponding slide. The other side wall 30 "is provided with a notch 34 (see in particular Figure 3), whose rear end has a flared shape. In other words, the height of this notch 34 is greater in its rear part, to ensure a movement of the locking member, as will be detailed in what follows. Finally, this side wall 30 "is hollowed out with a vertical hole 35 (see also FIG. 3), opening at the same time in the slideway 32 and the notch 34. This hole is intended for receiving the locking pin 50, as this will be explained in the following. The locking member 40 is constituted by an elastic thread in one piece, made for example of spring steel. This member 40 has a substantially constant diameter, typically between 2 and 3 millimeters. It comprises first a rectilinear section 41 whose end 42 abuts against the bottom of smaller diameter, belonging to the notch 34. This section also extends into the flared portion of the notch, so that there is a clearance between this section 41 and the walls opposite this notch, in a vertical direction. The section 41 has a certain elasticity, while being prestressed. In other words, it can move downwards relative to the notch 34 under the effect of an external force, but when this force is removed, this section returns to its upper position against the upper wall of the 'notch.
    This section 41 is extended by a so-called support region 43, generally U-shaped in rear view. This region 43, which extends opposite the rear end face of the body 30, is provided with a fold of material 44, against which can bear the end of a ski pole, as will be seen in this following. Finally the support region43 is terminated by a so-called stop portion 45, L-shaped in plan view. This section 45 has a wing 46, which defines a second end of the locking member 40. This wing 46 is intended to cooperate with the locking member to limit its axial movement, as will be seen in what follows.
    The locking pin 50, which is substantially cylindrical in shape, is slidable relative to the walls of the lid. For this purpose, it is hollowed out with a notch 51, in which the tilting portion 41 is received. The pin 50 is thus integral in translation with the member 40, namely that it can be displaced in the vertical direction, under the effect of a corresponding movement of the section 41. It will be noted that the transverse dimensions of the passage are slightly greater than those of this section 41, so as to allow a certain clearance between these two mechanical elements, in particular during the tilting of the aforementioned section. At its upper end, opposite the notch 51, the locking pin 50 is provided with a projection 52, of rectangular shape. As will be detailed below, this projection forms a tenon, capable of cooperating with a mortise formed in locking member 60.
    As shown in particular in FIG. 7, this locking member 60 is made in the form of a cylindrical element, for example a metal element, which is folded on itself in the manner of a U. It therefore comprises two parallel wings 61, 62 mutually connected by a rounded core 63. By way of example, the diameter of the locking member 60 is typically between 4 and 6 millimeters, preferably close to 5 millimeters in order to fit into the complementary shapes of the shoe.
    A first wing 61 is hollowed out with a groove 64, defining a mortise that can cooperate with the pin 52. In addition, the second wing 62 is hollowed out with another groove defining a flat 65, whose longitudinal edges can abut against the end 46 of the member 40. Note that the groove 64 is located further back than the flat 65, that is, it is closer to the core 63. The length of the flat, between its opposite longitudinal edges , is advantageously between 5 and 15 millimeters. This length defines the sliding stroke of the locking member 60 relative to the body 30 of the heel.
    The operation of the heel 1, described above, will now be explained in what follows. This heel has a locked configuration, in which the locking member 60 is immobilized relative to the body 30, in an advanced position. It also has an unlocked configuration, in which the locking member 60 is movable relative to the body 30, between this advanced position and a retracted position.
    Figures 2 to 5 illustrate more particularly the locked configuration of the heel. The tilting section 41 of the locking member 40 is elastically pressed against the upper wall of the notch 34 and, consequently, maintains the pin 52 of the pin 50 in the mortise 64 of the locking member. The latter is thus immobilized in its locking position, advanced relative to the body 30, namely that the free ends 61 'and 62' of the wings 61 and 62 project beyond the front end face of the body 30.
    In this position, these free ends 61 'and 62' form locking fingers, which penetrate into notches provided in a ski boot, not shown. These indentations, of a type known per se, are, for example, in accordance with those fitted to the shoes marketed by the company SCARPA under the reference MAESTRALE. In this locking configuration, the distance between the walls facing the core 63 and the body 30 is advantageously between 1 and 20 millimeters. These walls thus delimit an interspace 70, allowing the insertion of a point 81 of a ski pole 80.
    If it is desired to move the locking member 40 from its locked position described above to its so-called unlocked position, the tip 81 of the stick is inserted into the spacer space 70, so that the tip 82 of this point comes into support against the fold 44 (see Figures 8 and 9). This fold is then pressed along the arrow F1, so that the section 41 also tilts downwards with respect to the end 41 along the arrow F2. This induces a displacement corresponding, also downwards, the tenon 52 which then emerges from the mortise 64 according to the arrow F3. The fold 44 thus forms an actuation zone, making it possible to move the locking member from its active position to its inactive position, by pressing the ski pole.
    While maintaining this downward force, it is then to switch the stick 80 backwards, according to the arrow F4. Since the tenon no longer cooperates with the mortise, the locking element is then free to slide along the slideways 32. The free ends 61 'and 62' move towards the front wall facing the body, up to retract inside these slides along the arrow F5 (see Figures 10 and 11). They then no longer project towards the front of the body 30, so that they no longer cooperate with the indentations in the shoe. The latter is no longer immobilized relative to the heel, so that it can pivot upwards around the front stop. This position, said inactive or retracted from the locking member, therefore corresponds to a Nordic use, or hiking, fixation.
    At the beginning of the sliding movement of the locking member 60, as described above, the end flange 46 of the locking member 40 abuts against the rear edge 65 'of the flat (see FIG. 12 ). Then wing 46 progresses along this flat, until it abuts against the front edge 65 "thereof (see Figure 13). These two opposite edges thus define end stops for the sliding movement, which is allowed to the locking member. In other words, in the normal framework of use of the heel, this locking member can not move beyond these two aforementioned edges 65 'and 65 ".
    If it is now desired to move the blocking element from its retracted position to its initial blocking position, the point 81 of the stick is introduced into the hollow stud 18 (see FIGS. 14 and 15). Then, the stick 80 is tilted forward, according to the arrow F6, which allows to slide the blocking element forward. At the end of this sliding movement, represented by the arrow F7, the pin 50 is again facing the mortise 64. By elasticity, the section 41 is lifted upwards (arrow F8 in FIG. 17) and pushes the tenon 52 in this mortise 64, which locks again the locking element 40.
    As seen above, the body 30 is pivotable relative to the shaft 20, along a vertical axis. In use, the spring 24 pushes the balls 25 against the inner walls facing the body, so as to create a resistant component against this pivoting. Depending on the preload of the spring 24, it will be possible to control the resistance and / or the amplitude of this pivoting. Thus, with a highly preloaded spring, this pivoting can only occur in the presence of a high external force.
    In the embodiment described and shown, the elastic thread 40 provides on the one hand the locking function and, on the other hand, the stop function thanks to the section 45 and the wing 46 of the latter. This is advantageous insofar as a single mechanical member provides two functions. As a variant not shown, it could be provided to produce two independent mechanical members, providing the respective functions of locking and abutment.
    The heel of the invention can be integrated into a binding, well suited for different types of ski. Among others, the MEIDJO fastener manufactured by THE M Equipment.
