EP1481713A1 - Platform for raising a snowboardbinding - Google Patents

Abstract

The platform has a fixation unit mounted on a plate. The plate has two hooks reversibly cooperating with openings (23, 24) on front and back plates (9, 11) for positioning the plate and fixation unit at different predetermined longitudinal levels. The front and back plates are mounted on recesses (14) that are present on an upper surface of the platform, such that the hooks are placed in the recesses.

Description

The invention relates to a platform for receiving and raising the components of the attachment of a user's shoe to a board slides on snow.

Generally, a ski binding is composed of two cooperating elements with the front and back of the shoe. These elements, namely the toe piece and the heel piece, are usually arranged on either side, and equidistant, from a point called "Mid boot" determined on the ski. Depending on the size of the shoe, it is necessary to make the adjustments in the longitudinal position of the stop and the heel.

State of the art

• une embase en forme de plaque, destinée à être montée de façon quasi défmitive sur la planche de glisse, ladite embase présentant au moins une rangée longitudinale de logements ;
• une platine sur laquelle est monté l'élément de la fixation, ladite platine étant équipée sur sa face inférieure d'au moins une rangée de crochets aptes à coopérer avec les logements de l'embase, de manière à permettre le positionnement de la platine à différents niveaux longitudinaux prédéterminés ; et
• un moyen de verrouillage de la platine sur l'embase.

We know from document FR-2,756,747 a device for mounting a fastening element on a snow gliding board allowing its longitudinal displacement as a function of the shoe size of the user and comprising:

• a plate-shaped base, intended to be mounted almost definitively on the gliding board, said base having at least one longitudinal row of housings;
• a plate on which the fixing element is mounted, said plate being equipped on its underside with at least one row of hooks able to cooperate with the housings of the base, so as to allow the positioning of the plate to different predetermined longitudinal levels; and
• means for locking the plate on the base.

Also known from document EP-1,310,276 is a device for make an interconnection between a fastening element and a gliding board on snow and to adjust the longitudinal position of the fastener so to ensure an adjustment of the two fastening elements according to the size of the shoe of the user. The device comprises three plates arranged one on top of the other and that can move relative to each other. The device is inserted into a housing provided on the upper face of the gliding board.

However, such a device with its multiple plates is relatively complex and in addition requires a significant number of holes as well of each of the plates constitutive of the gliding board to ensure its joining. The plates and the corresponding screws cause a complete clamping of the pad area of the board. The holes also cause a weakening of the upper structure and internal of the board at this level. In addition, the presence of housing in the area of skate causes a change in behavior of the board.

It also appears that these mounting devices have only been provided to be mounted directly on the ski, but not on a raising platform, which must itself be secured to the upper face of the ski.

Let us briefly recall that a platform allows, on the one hand, to enhance the fixing relative to the upper level of the ski, and on the other hand, ensuring an unclamping the binding relative to the ski, that is to say to limit the influence of the stiffness of the user's shoe on the ski's intrinsic stiffness.

Statement of the invention

The main problem which the invention proposes to solve consists in providing a raising platform, allowing to have in addition fixing elements which are easily adjustable along the longitudinal axis of the snow gliding board. A second problem is that of using a platform to separate the left and right presses, in order to transmit the forces applied by the user on the board and transmit the forces generated more directly at the edge left or right edge. A third problem is that of developing a device for mounting the fastening elements on an adjustable board longitudinally and which makes it possible to choose a particular unlocking at the level of the zone skate.

The invention therefore relates to a raised platform equipped with at least one fastening element, and which is intended to be mounted on the upper face of a board for gliding on snow.

In accordance with one aspect of the present invention, the elevation platform is characterized in that it has at least one recess made on its face upper, and in that the fixing element is mounted on a plate having hooks under its underside, said hooks reversibly cooperating with openings made on a wafer, so as to allow the positioning of the plate and the fastening element at different predetermined longitudinal levels, the plate itself being mounted on the raising platform above the or recesses, so that the hooks are housed in the recess (s).

In other words, thanks to the plate embedded in the recess (s), a interface between the added platform and the plate of the element (s) of the fixing allows to adjust the longitudinal position of the latter. Due to presence of the recess (s), the height of the fastening elements, following the adding the platform is not going to be too important. The adapted platform assembly and fixing thus comprises several parts cooperating with each other and proving particularly advantageous for facilitating operations for adjusting the position of binding, especially for skis used on the rental market.

This set with platform also allows very easy adjustment of the general position of the toe piece and the heel piece, with a large amplitude, without require drilling on the platform. This positioning is carried out without mechanical play in a longitudinal or vertical direction.

In a particularly favorable embodiment, the plate can have downward curved side edges. These side edges can then penetrate into the recess (s) made on the upper face of the platform. These side edges can also enter a groove made on the face upper part of the platform, at the outer periphery of the recess (s). Platinum may also have side edges curved downward. These side edges can penetrate a groove made on the upper face of the platform, in outer periphery of the recess (s). The blister may present favorably two rows of openings, each of these two rows corresponding to an area of the platform.

Advantageously, the platform can be formed of two parts mechanically separated longitudinal sections. Locking the plate on the plate can be done by means coming to be housed between the two longitudinal parts of the platform, in order to avoid any further drilling of the platform and / or the board.

In a second embodiment, the plate can optionally have a central groove embedded between the two longitudinal parts of the platform. According to a first variant for choosing a type of unclamping, the plate can present means ensuring its attachment to the platform. According to a second variant and to choose another type of unlocking, the plate may have means ensuring its attachment to the platform and to the snow gliding board.

Detailed description of the invention

A classic snowboard, such as an alpine ski (1) includes a front area with a spatula, a rear area with a raised heel, a central area called the skate area (2), an outer face (3) and a face lower forming the gliding sole (4) delimited on both sides by the two side edges (6).

A platform (7) for raising the elements of the binding, that is to say the front stop (8) and the heel piece is positioned at the level of the skid zone (2). A first type of monobloc platform (7) can be used (see Figures 1 and 2). The platform (7) receives two plates (9 and 11) which are firmly fixed by appropriate screw connections, using the holes (12) drilled for this purpose in the plates (9 and 11). In the form illustrated in Figure 2, the front plate (9) which will accommodate the plate front receiving the stop (8) has a length less than the rear plate (11) which will accommodate the rear plate receiving the heel.

According to the invention, the platform (7) has two recesses (14 and 16) formed on its upper face (17). The front recess (14) is formed at the front of the platform (7) and is intended to receive the front plate (9). The rear recess (14) is provided at the rear of the platform (7) and is intended to receive the plate rear (11). The front recess (14) thus has a length very slightly greater than the length of the front plate (9) and the rear recess (16) has a length very slightly greater than the length of the rear plate (11). The width of the two recesses (14 and 16) is similar to the width of the platform (7).

Alternatively, the total width of the recesses (14 and 16) may be reduced in the case of the monobloc platform (7). This allows to have two zones by plate, or in total four half-recesses, which are located in below the openings (23 and 24) which receive the hooks of the plate. By reducing the total width of the recess and keeping a full central area (not shown), it material will remain on the upper part of the platform (7), which improves its mechanical resistance.

A second type of platform in two longitudinal parts (18 and 19) mechanically separated (see Figures 3, 4 and 5) can also be provided. These platforms in two parts could be similar to those described in the documents FR- 2.827.184, FR- 2.831.453 and FR- 2.831.829. Both front and rear recesses (14 and 16) are formed both in the two longitudinal parts (18 and 19) in thus creating four half-recesses (14a and 14b). The width of the two recesses (14, 14a, 14b and 16) is provided in the two longitudinal parts (18 and 19) so as to leave two lateral ribs (21 and 22) at the free edges of each of the two longitudinal parts (18 and 19).

The plates (9 and 11) can be placed on the platform (7, 18 and 19) during operations that are completely separate from mounting the plate, and for example from leaving the ski manufacturing plant (1). Installation of fastening elements through the characteristic plates is then carried out either by the user fmal, or by the operator of a rental ski park.

With reference also to documents FR-2,756,747 and FR-2,833,850, each of these plates (9 and 11) has two rows of housings or openings (23 and 24), of substantially rectangular shape made in the thickness of the plate metallic forming the plates (9 and 11). These openings (23 and 24) are distributed on either side of the median longitudinal plane of the plate (9 and 11), in the part central of the latter. Another establishment could be possible, as soon as the hooks located in the plate are installed according to the additional configuration.

At the front of the front plate (9), screws (13a) will secure the this plate (9) at each of the two longitudinal parts (18 and 19), crossing the holes (12) drilled for this purpose (see Figure 7). These screws (13a) have a length less than the thickness of the platform (18 and 19). Such a joining allows a unclamping before the ski (1). At the rear of the front plate (9), at an area plate (9a) tilting towards the platform (18 and 19), screws (13b) will ensure the attachment of this plate (9) to each of the two longitudinal parts (18 and 19) (see Figure 8). These screws (13b) have a greater length and are anchored thus both in the platform (18 and 19) and in the ski (1).

Equivalently, at the front of the rear plate (11), screws will ensure the connection of this plate to each of the two longitudinal parts (18 and 19), by crossing the holes (12) drilled for this purpose (see Figure 4). These screws have a greater length and are thus anchored both in the platform (18 and 19) and in skiing (1). At the rear of the rear plate (11), screws will ensure the securing of this plate (11) to each of the two longitudinal parts (18 and 19). These screws have a length less than the thickness of the platform (18 and 19). Such an attachment allows back unlocking of the ski (1). This type of anchoring common saves the screws used and avoids excess drilling of the platform.

In a second embodiment (see Figure 9), the plate (9) has a central groove (25) provided between the two rows of openings (23 and 24). This central groove (25) will be fitted between the two longitudinal parts (18, 19) of the platform. The securing screw (not shown) of the plate (9) is positioned at the bottom of the central groove (25).

The plate (9 and 11) has on each side folded portions (26) coming in contact with the platform (7), and more precisely coming into and resting on at the bottom of the recess (14 and 16). Due to this configuration, the central part of the plate (9 and 11) is found substantially at the same level as the upper face (17) of the platform (1), thus allowing the introduction of a hook into the openings characteristics (23 and 24).

As illustrated in Figures 3 and 4, each of these plates (9 and 11) receives by its upper face a plate (27 and 28). Each plate (27 and 28) has two rows of hooks (29 and 31) made by cutting and stamping and oriented under the underside of the plate (27 and 28). The plate (27) intended to receive the stop, is located at the front, has two series of hooks (29 and 31) while the plate (28) intended to receive the heel, is located at the rear, and comprises four series of hooks (not visible). Of course, this number can vary depending on the size and mechanical stresses that one wishes to see supported by the device.

The plate (27 and 28) has on each side folded portions (32) coming to the contact of the upper face (17) of the platform (7), and more precisely coming penetrate into, and lean against, the recess (14 and 16). Two grooves (no shown) can be made on the upper face (17) of the platform (7, 18 and 19), at the outer periphery of the recess (s) (14, 14a, 14b and 16) and are hollowed out in the two lateral ribs (21 and 22). Side edges curved down (32) of the plate (27 and 28) will enter the two grooves.

The plate (27 and 28) will rest on the plate (9 and 11). The folded portions (32) of the plate (27 and 28) will cover the folded portions of the plate (9 and 11). Due to this configuration, the central part of the plate (27 and 28) is appreciably very slightly raised relative to the upper face (17) of the platform (7, 18 and 19), thus allowing the height of the elements of the binding and so for the skier's shoe.

The hooks (29 and 31) of the plates (27 and 28) cooperate in a reversible manner with the plate (9 and 11) by each penetrating respectively into the openings (23 and 24). The hooks (29 and 31) and the openings (23 and 24) may have conformations similar to those described in document FR-2,833,850. Thanks to the presence of the folded portions (26) of the plate (9 and 11), the hooks (29 and 31) pass through the openings (23 and 24) are housed in the recess (s) (14, 14a, 14b and 16) of the platform (7).

The locking of the plate (27 and 28) on the plate (9 and 11) is effected by a screw (not shown) passing through two corresponding threads. A first internal thread (33) is produced through the plate (27 and 28) on its longitudinal axis median and a second thread (34) is formed in the plate (9 and 11) on its axis longitudinal median. The longitudinal blocking of the plate (27 and 28) relative to the plate (9 and 11) requires only one screw. In the case of the use of a platform in two longitudinal parts (18 and 19), the locking screw will be housed in the central central area between the two parts (see Figure 5).

To allow locking of the plate (27 and 28) in different positions longitudinal with respect to the plate (9 and 11), the latter therefore has a plurality of second threads (34) regularly spaced as a function of the spacing between each of the openings (23 and 24) of the plate (9 and 11) and each corresponding hooks (29 and 31) of the plate (27 and 28).

Additional threads (36) are provided, in the illustrated form, at the four corners on each plate (27 and 28). These threads (36) are intended to accommodate the mounting screws of the stop (8) and the heel on the plate (27 and 28). In practical, the threads (33 and 34) for locking the plate (27 and 28) on the plate (9 and 11), and the threads (36) for mounting the fixing on the plate (27 and 28) are different, to avoid any risk of confusion, when adjusting the position of fixation.

The plate (27 and 28) and the plate (9 and 11) are covered by several elements (37) made for example of plastic, and which provides a covering of all. The upper face of these cover elements (37) serves as a support for the installation of the stop (8) and of complementary members. These cowling elements (37) allow in particular to avoid any intrusion of snow which could disturb the operation of the plate (9 and 11) and of the plate (27 and 28).

The present invention is not limited to the embodiments described and illustrated. Many modifications can be made, without leaving the framework defined by the scope of the set of claims.
