Definitions

• Device for adjusting the position of a binding on a gliding board, in particular a snowboard and gliding board suitable for such a device for adjusting the position of a binding on a gliding board, in particular a snowboard and gliding board suitable for such a device.
• the present invention relates to a device for adjusting the position of a binding on a gliding board. It relates more particularly to a device suitable for a board of the 'Snowboard' type.
• the invention also relates to a snowboard fitted with the device.
• Snowboarding is done using an elongated board, the front end of which, at least, is raised to form the tip.
• the user's two shoes are immobilized on the board by suitable retaining elements.
• the positions adopted for the practice of this sport are very variable depending on the disciplines practiced, the level or habits of the user, or according to his morphology.
• the feet are very wide apart on the other and are very inclined relative to the longitudinal axis of the snowboard in a substantially transverse position, generally not parallel to each other.
• the surfers adopt a so-called "duck” position of the feet to allow the practice indifferently in one direction or another.
• the feet are less spaced from each other and approach, in inclination, the median longitudinal axis.
• Patent AT 1387/92 discloses an adjustment system of this type for the support of a snowboard binding. According to this device, the choice of positions remains limited, in particular along the longitudinal direction of the board. Similarly, the adjustment requires the use of a tool such as a screwdriver and therefore makes handling long and tedious, and therefore generally impossible in the field. These devices are also not suitable for rental where the ease and speed of adjustment are paramount.
• One of the aims of the present invention is therefore to propose a device for adjusting the position of a binding which actually provides a wide choice of adjustment possibilities, in particular in angular orientation and in longitudinal position while remaining easily and quickly maneuverable without having special tools.
• Another object of the invention is to propose a device which adapts, in particular in snowboarding, to most of the current fixing base systems which uses the usual standard 4x4 thereby serving as an adjustment interface between the snowboard and the base.
• the present invention also relates to a snowboard particularly suitable for receiving the position adjustment device according to the invention.
• One of the goals is therefore also to offer a snowboard with integrated adjustment device which adapts to most of the current fixing base systems used.
• the board offers a range of continuous adjustment in the longitudinal position allowing to obtain an adaptation to the different disciplines practiced in snowboarding.
• Another object of the invention is also to propose a snowboard which has a high resistance to tearing of the bindings under the harshest conditions of use.
• the present invention is presented as a device for adjusting the position of a binding on a gliding board intended to cooperate in a portion of rail formed in the board, characterized in what he understands:
• An actuating means which controls the central rod in translation to modify the relative vertical position of the sliding member inside the rail portion; between a position freed from the plate in rotation and in translation along the portion rail and a clamping position during which the lower surface of the plate compresses the friction means against the upper face of the board.

It is therefore not in the spirit of the present invention to limit itself to the use of a particular type of fixing.
• each device comprises a central plate 3 connected to the board by a particular mechanism which will be described later.
• a base 4 whose main function is to support the shoe retaining means is shown in dotted lines by way of example. The base is secured to the plate and is oriented along a main axis O forming an angle of inclination ⁇ relative to the longitudinal axis (M 1 ).
• One of the objects of the invention is to be able to vary the angle of inclination ⁇ , at will, by releasing the central plate 3 in rotation and by providing a rapid locking mechanism in the desired angular position.
• the snowboard also includes two portions of rails 5 arranged along the longitudinal axis (11 1 ) and spaced from one another.
• the length of each portion of rail and the spacing between them are parameters easily determinable by those skilled in the art to cover all, or at least most, of the usual adjustments used and sought by users.

• the central housing 32 has a sufficient depth relative to the surface 31 to contain the actuating means 23 without exceeding the lever 231 when the latter is in the retracted position corresponding to the clamping position of the plate.
• the device operates as follows in the unlocked position, shown in FIG. 5, the lever 231 is raised, so that the cam eccentric member which is integral with it, is released from the surface of the central plate 3
• the plate being mounted by a pivoting link sliding on the rod 21 can then be oriented in the desired angular position.
• the sliding member, or slide 20 is released in translation in the rail portion, also making it possible to move the entire device in the chosen direction A or B.
• a sliding member 20 is housed inside the rail portion 5 and is connected to a central rod 21 integrally.
• the central rod passes through the central bore 33 of the plate. It is mounted free in axial translation relative to the plate by a slide link. To allow transmission of the vertical movement, the rod is locked in rotation by a flat 211.
• the actuating means 23 has a lever 231 which rotates an annular ramp member 234 mounted by a pivoting link sliding relative to the central rod 21 and which acts on one or more radial lugs 210 of the central rod to move that -ci in axial translation upwards to reach the clamping position and, conversely downwards, to reach the released position.
• the central rod is provided with two radially opposite lugs 210.
• the annular ramp member has two ramp surfaces 234a for guiding the pins and which each have a progressive slope ending in the high position with a radial recess 234b for locking each lug in the clamping position of platinum.
• the central plate 3 has an upper receiving surface 31 and a central housing 32 of sufficient depth relative to the upper surface, to contain the annular ramp member without protruding either from it or from the end of the central rod relative to the upper receiving surface 31 when the high blocking position is reached.
• the device comprises a second housing 34 formed under the plate, set back with respect to the lower surface 30 of the plate in contact with the friction means, which communicates with the central housing 32 on the one hand and which opens out through an opening 34a on the side of the plate on the other hand.
• the lever meanwhile, is provided with an arm 231a which connects the annular ramp member 234 through said housing and which extends out of the opening 34a by a lever 231 b actuable in rotation.
• an elastic means such as one or more Belleville washer (s) 24, housed in the rail portion and which offers an elastic resistance to compression for keep the sliding member under pressure. More specifically, the 'Belleville' washer is simply mounted through the central rod and housed between the slide 20 and a support washer 25 whose width is chosen greater than the opening 50 of the rail.
• the clamping passage of the device to the released position, and vice versa is done simply by actuating the lever 231 b of the lever by a rotation of about a quarter of a turn.
• Figures 9 and 10 detail another variant of the invention with an actuating lever offset from the plate; which has the advantage of allowing adjustment without having to disengage the shoe from the retaining means directly or indirectly attached to the plate.
• the device has an actuating means 23 which comprises a transmission element 235 housed, at least in part, in the rail portion 5.
• the element is connected to the central rod 21 by a sliding pivot connection. It has a first elongated portion 235a which ends with a support means 236 offset by a certain distance d1 relative to the axis of the central rod.
• the support means 236 is in the form of a cylindrical part of width greater than the opening 40 of the rail.
• the actuating means has a second elongated portion 235b which extends on the side opposite to the first portion, and is connected by an offset clamping member 237, located at a distance d2 from the axis of the rod.
• the distance d1 of the first portion 235a is less than the distance d2 of the second portion 235b, so that the clamping action of the offset clamping member 237 causes a lever effect which displaces the central rod 21 in translation axial down to the clamping position of the plate.
• the transmission element 235 comprises, between the two elongated portions 235a, 235b, a support disc 235c, through which the central rod passes.
• the disc 235c bears against the sliding member 20 to push it down, by lever effect generated during the clamping action of the offset clamping means 237.
• the offset clamping means 237 comprises:
• a second sliding member or slide 237a housed inside the rail portion
• the rod 237b is provided with a threaded portion on which is screwed a threaded adjustment means 237e.
• the eccentric member 237c is pivotally mounted directly on the threaded adjustment means by means of two radial pins 237f.
• the adjusting means 237e can be a hexagon nut for example. Its function is to allow the adjustment of the clamping force of the clamping means 237.
• the central rod 21 of the device is also provided with a threaded upper portion 212a. It is blocked in translation relative to the plate by an adjustable threaded element 212b, of the nut type for example. This element allows a backlash of the device.
• the threaded element takes place in a central housing 32 sufficiently wide to be able to handle it by means of a tool such as a key.
• Figure 1 1 shows the device in a locking configuration.
• the lever 237d of the offset clamping member 237 is in the retracted position; which has the effect of placing the cam of the eccentric member 237c in the support position on the end of the second elongated portion 235b, which therefore moves downwards and approaches the member sliding 237a which moves it upwards by translational driving of the rod 237b.
• the downward support on the end of the second elongated portion is transmitted by an upward support from the support end 236 and by a greater traction force due to the leverage on the rod central which tends to bring the plate closer to the surface of the board and to compress the friction means 22.
• the lever In the unlocked position, the lever is in the high position; so that the cam of the eccentric member 237c no longer applies a clamping force to the end of the second elongated portion 235b. Therefore, the downward traction force exerted on the slide disappears which frees the device in translation, and the plate which no longer exerts compression on the friction means is released, in turn, in rotation.
• the entire device including the offset clamping member can be moved in translation in the rail portion in the desired direction A or B.
• the friction means plays an important role since it has the function of creating between the lower surface of the plate and the upper surface of the board, an interface which when it is subjected to a compressive force , participates in the immobilization of the plate in rotation by friction effect.
• Such a means can consist of a disc of material chosen from those having significant compressibility and elasticity properties.
• materials likely to be suitable mention may be made in particular of natural and artificial rubbers, certain plastics, cork and felt.
• the disc constituting the friction means can be glued or screwed on the lower surface of the plate or on the upper surface of the board in order to facilitate the movement of the device in the rail portion.
• the plate has the shape of a disc provided with at least four threaded holes 3a, 3b, 3c, 3d forming a quadrilateral for the reception of a suitable fixing base (FIGS. 3 and 4).
• the holes are separated two by two by a distance of 4 cm to meet the usual standard of snowboarding.
• the turntable can take other forms than that of a disc.
• it may be an elongated plate of substantially identical shape to the sole of a shoe for the direct reception of a snowboard binding of the 'shell' type or the like.
• each rail portion consists of a profiled element 6 having a substantially rectangular transverse profile.
• the profiled element also comprises lateral anchoring edges 67, 68 which extend the bottom wall and extend outwards, in order to improve the resistance of the anchoring in the structure of the board.
