The present invention relates to an arrangement for

  the fixing on a gliding board of a device for attaching a boot, resting on the one hand on a plate positioned directly on the gliding board and comprising first connecting means and a lower element of the fixing device comprising second connecting means adapted to cooperate with the first connecting means. The invention therefore also relates to a gliding board plate, a bottom element of a shoe attachment device, and a fastening device and a gliding board as such.

  It is known from document FR2739572 that a device for attaching a ski boot can be fixed to the ski by means of a plate comprising a latch movable in translation under the effect of a spring and a lever. actuation of the latch, to release the lock and release the plate of its grip on a base fixed on the ski, this base comprising notches cooperating with the latch of the plate. This solution simultaneously makes it possible to fix the fastening device of a ski boot and to adjust its positioning to adapt it to any shoe size. A first disadvantage of this solution comes from the fact that the fixing on the ski of this fixing device requires the continuous actuation of a lever, which is not user friendly. A second disadvantage of this solution stems from its mechanical complexity, the number of parts used inducing significant cost and risk of failure.

  The document US2004 / 0051278 describes a solution similar to the previous one, in which the fixing device is fixed to the gliding board by means of a sliding plate in slides of a base mounted on the ski, this plate comprising a cooperating lever .R493.12EN.92 DA depot 2 with a latch movably mounted in lateral translation to cooperate or not with teeth of the base on the ski. This solution has the same disadvantages as the previous one.

  A general object of the present invention is a solution for attaching a shoe attachment device to a gliding board does not include all the disadvantages of existing solutions.

  More specifically, a first object of the present invention is a more user-friendly solution.

  A second object of the present invention is a simpler and less expensive solution.

  The invention is based in particular on the separation of the adjustment functions of the longitudinal positioning and fixing on the ski of the fixing device. Thus, the invention provides an automatic fixing solution, requiring no tools or actuating handle or lever, the device for attaching a shoe to a plate connected to a gliding board, this plate being moveable or not.

  More specifically, the invention is based on an arrangement for fixing on a gliding board of a shoe attachment device, comprising a lower element of the shoe fastening device and a plate of the gliding board, characterized in that that the fixing between the lower element of the fastening device of a shoe and the plate is formed by means of a light of a first of these two elements cooperating with a finger of a movable lock of the second of both of these elements. 30 .R493.12EN.92 DA deposition 3 The light may comprise a first part with a guide line allowing the lock to move against the force of a compression spring when the lower element for the device shoe attachment is moved relatively to the plate, then a second portion with a locking line oriented in a direction close to that of the movement of the latch, allowing the spring of compr a sudden detent to position the latch finger in a locked position within the light.

  According to one variant, the cooperation between the lower element and the plate may comprise a system of several wide-headed screws and oblong slots for filling at least part of the three-dimensional maintenance function of these elements. According to another variant, the cooperation between the lower element and the plate may further comprise a plurality of holding teeth allowing a function of longitudinal retention of these elements.

  Fixing the lower element on the plate can be obtained by a relative movement of these two elements in the longitudinal direction, the latch being driven by a transverse translation movement on one of the two elements and the locking line of the second part of the light being also substantially transverse.

  The light may have an initial point substantially aligned with the end point in the longitudinal direction. Its guide line of its first part may have a continuous slope, which may be approximately 45 degrees with respect to the direction of movement of the latch, the light generally having a V-shape. According to one embodiment, the light is disposed on the plate and the latch positioned within a housing of the lower element, in a mobile manner in translation, and connected to a compression spring.

  The invention also relates to a gliding board plate as such for fastening to this gliding board a shoe fastening device, characterized in that it comprises a light having a first part able to form a shoe. ramp relative to a direction of relative movement of a latch of a shoe attachment device and a second portion substantially parallel to the direction of relative movement of the latch, adapted to form a locking line of the latch of the fastener of the shoe; shoe.

  According to an alternative embodiment, the light has a V-shaped shape. According to an alternative embodiment, the plate further comprises one or more oblong aperture (s) capable of receiving a flat-head screw. a shoe attachment device for maintaining it, each light having a length substantially equal to the distance between the initial and final points of the light, measured in the direction defined by the axis of the oblong slots.

  The plate may further comprise one or more teeth adapted to receive a complementary tooth of a shoe attachment device 25 to ensure its maintenance.

  Finally, the plate may comprise lateral rails capable of a movable connection on a gliding board. The invention also relates to a lower element of a gliding shoe attachment device, comprising a latch positioned in a housing movably in translation relative to this element, the latch being connected to a compression spring and this lock comprising a lower finger capable of cooperating with a light of a plate of the gliding board.

  According to one embodiment, the lock is connected to the compression spring on a first end and its second end is accessible through a housing window for manual unlocking of the lock.

  According to one variant, the lock may comprise longitudinal holding teeth. The finger and / or the longitudinal holding teeth may be parts formed by a stamping process.

  The invention also relates to a gliding board comprising at least one plate as defined above.

  This plate can be movable longitudinally by slides. The gliding board may comprise two longitudinally movably mounted plates connected by a mechanism for co-ordinating their simultaneous movement. Alternatively, the plate may be fixed or integrated into the gliding board.

  The invention also relates to a shoe binding device for a gliding board, characterized in that it comprises a lower element as described above.

  This lower element can be separate and separable, or integrated and inseparable from the fixing device. Finally, the invention relates to a gliding board comprising a shoe attachment device fixed to the gliding board by an arrangement as described above.

  These objects, features and advantages of the present invention will be set forth in detail in the following description of a particular embodiment made in a non-limiting manner in relation to the appended figures among which:

  FIG. 1 represents an exploded perspective view of a ski binding device on a ski according to an embodiment of the invention; Figure 2 is a bottom perspective view of a lower member of the shoe fastener; Figure 3 is a side view of a boot fastener lock; Figure 4 is a perspective view from below of the latch; Figure 5 is a top view of a ski plate cooperating with the shoe attachment device according to the embodiment; FIG. 6 shows the relative positioning of the connecting elements of the lower element of the shoe binding device with the complementary connecting elements of the ski plate in an unsecured configuration; Figure 7 the relative positioning of the connecting elements of the lower element of the shoe attachment device with the complementary connecting elements of the ski plate in a fastening configuration; Figure 8 schematically illustrates the operation of the connecting elements according to the concept of the invention.

  The figures illustrate the implementation of the invention in the context of skiing. However, this concept could be implemented on all boards of glide, for example surfing.

  FIG. 1 thus represents a device 30 for fastening a boot, comprising a front stop 31 and a heel piece 31 ', these two shoe attachment sub-devices including similar connecting means in their lower part 32, 32', for their attachment to respectively front plates 2 and rear 2 ', movably positioned on a ski 1, through front 3 and rear 3' slides.

  In known manner, these plates 2, 2 'are connected by a mechanism 4 allowing their simultaneous movement to maintain their symmetry around a central point regardless of the chosen configuration.

  FIG. 2 illustrates in more detail a lower element 32, or 32 ', of the front fastening device 31, or rear fastener 31', which notably comprises a housing 35 for the reception of a lock 40, which will be described below. after referring to Figures 3 and 4, the latch being movable in translation in the transverse direction under the effect of a spring 50 not shown bearing on the one hand on a side end 33 of the housing 35 and on the other hand on one end 43 of the latch 40. The other lateral end of the housing 35 has a window 34 allowing access to the second end 44 of the latch 40, for its actuation during a phase unlocking which will be explained later. Finally, this lower element 32 comprises three locations 36 for screwing head screws 37 whose function will be explained later.

  The lock 40, illustrated in Figures 3 and 4, comprises a substantially flat bottom face with a vertical finger 41 and holding teeth 49, obtained by stamping.

  The plate 2, 2 'of the ski, illustrated in FIG. 5, comprises a slot 10 comprising a first portion with a boundary 11 forming a guide ramp 11 and a second portion with a boundary 12 forming a locking line, substantially transverse to the plaque. This plate further comprises holding teeth 19, two oblong front slots 20 which we will call buttonholes, and a partial rear light. Lateral slides 17 allow its longitudinal movement in slides 3 arranged on the ski 1. Alternatively, this plate could be fixed on the ski, either in the form of a separate element attached to the ski or in the form of a integrated part of the ski.

  Figures 6 and 7 schematically illustrate the operation of the previously described elements in a fixing phase of a shoe attachment device. In a first step, the fixing device is positioned on the plate so that the finger 41 of its latch occupies the initial position 13 within the light 10, the wide heads of the front screws 37 then penetrating into the large circular openings 21 the rear end of the buttonholes 20 to position themselves under the surface of the plate 2.30 .R493.12EN.92 DA deposition 9 The fixation on the ski of the shoe fastening device is automatically obtained by a simple longitudinal movement of the fastening device of shoe, ie in the direction of the length of the ski, according to a short race. Under the effect of this longitudinal movement, the finger 41 of the latch 40 will initially be guided by the ramp 11 of the first part of the light 10 of the plate, compressing a spring 50 connected to the latch 40, as shown in FIG. Figure 8. During this phase, the latch 40 moves in transverse translation relative to the lower member 32 of the shoe attachment device.

  At the end of this first phase, the finger 41 reaches a breaking point 15 located at the end of the first part of the light 10 and enters the second phase in which it faces the second part of the light which is extends substantially in the same direction as the degree of freedom of translation of the latch 40 under the fixing device 32. Under the effect of the compressed spring 50, which suddenly relaxes, the latch 40 moves rapidly in translation, until the finger 41 reaches the end 14 of the light 10. This second rapid phase is accompanied by an audible click and a sudden locking of the fixing device, which informs the user that the Shoe attachment device is well positioned. The direction of the locking line 12 of the second portion of the light 10 is such that it prevents any backward movement of the finger 41 and thus ensures the stable holding of the finger 41 in this fixing position.

  Only the manual actuation of the latch 40, for example by a tool that would be actuated at the opening 34 of the lower element of the shoe attachment device to push the end 44 of the latch 40, until the finger 41 exceeds the breaking point 15 allows the unlocking and release of the fixing device. As a variant, this unlocking function could be implemented by means of an articulated lever mounted on one of the elements and capable of acting on the latch to obtain its unlocking.

  In addition to the preceding mechanism of automatic fixing, the described embodiment provides means for three-dimensional support of the shoe attachment device. Thus, when the finger 41 of the latch 40 is in its final position 14 in the light 10, the shoe attachment device has made a short longitudinal stroke on the ski, which allows to bring the screws 37 to the front ends 22 of the buttonholes 20. This configuration definitively blocks any forward displacement of the shoe attachment device as well as any lateral displacement, since the width of the slots 22 substantially corresponds to the diameter of the screws 37. On the other hand, the wide heads of the screws 37, of diameter greater than the width of the light 20 at point 22, also guarantee the vertical maintenance of the device. In addition, in this locked position, the holding means 49 of the latch 40 are in abutment in front of the complementary holding means 19 of the plate, which guarantees the longitudinal retention by preventing any retreat of the fixing device.

  These holding means guarantee the durable locked positioning of the shoe attachment device, allowing it to withstand high stresses during the practice of skiing. Any other form of holding means could be envisaged without departing from the concept of the invention. The finger 41 of the lock also participates in this holding function. In its final position, it withstands the longitudinal stresses exerted on the fixing device. Advantageously, the second portion of the light, delimited at the rear by the locking line 12, may comprise a non-parallel front line so that the width of the light narrows towards its end 14 to ensure proper retention .R493. 12FR.92 DA deposition 11 of the finger 41 in its final positioning and reduce the playability of the device. This finger could alternatively be replaced by a wide-head screw similar in shape and operation to the screws 37, which would enhance the longitudinal holding performance while adding vertical support.

  Finally, the concept of the invention is based on this combination between the light 10 on the one hand and the latch 40 on the other hand, allowing a positioning and a very simple and easy-to-use automatic attachment of the shoe attachment device. The light could have different shapes from the one illustrated to fulfill the same function. The imposed points are the starting point 13, corresponding to the latch in its rest position under the fixing device, the spring 50 being preferably close to its rest position, as well as the arrival point 14, which also allows the lock to get closer to its stable state of rest. For this reason, the two points 13 and 14 are aligned in the longitudinal direction in the example shown. Then, the rear locking line 12 of the second portion of the lumen is preferably in a transverse direction, perpendicular to the longitudinal direction, to represent an obstacle to any automatic backward movement of the fastener. The breaking point 15 between this rear edge 12 of the lumen 10 and the edge 11 of the first portion of the lumen 10 corresponds to a certain level of compressive force of the spring, defined as a compromise between a large force to prevent any unlocking. accidental device while allowing manual unlocking and automatic locking. To achieve this automatic locking, the first part of the light 10 has been represented by a ramp 11 having a continuous slope, close to 45 degrees relative to the longitudinal direction, which allows a continuous effort of displacement of the device in the initial phase lock, before the click. This deposition 12 gives a V-shape of this light-guiding part 10, the two bars of the V being the lines 11 and 12, and the vertex of the V the point 15. This geometry and the operation of the device are schematically represented in FIG.

  However, as a variant, any other discontinuous shape could be envisaged for the first part of the light 10, as long as a slope is maintained at an angle allowing the finger 41 to move without locking until it reaches point 15. The solution is described with a overall V-shaped light, however the edges 11 and 12 are particularly important in guiding the finger 41 of the latch 40. The other edges of the light 10 could be any while obtaining a satisfactory operation of the device. For this reason, we will understand by light a broad notion of the term.

  The assembly has been designed for transverse translation movement of the latch under the fixing device, but any other direction of translation could be envisaged, the light of the plate being subjected to a simple rotation to adapt to the direction of the translational movement. lock. Similarly, the assembly has been designed for a longitudinal displacement of the shoe attachment device in its fixing phase on the ski. However, any other direction of attachment is theoretically possible, the geometry of the various elements easily reproducing in any other direction.

  On the other hand, the means of cooperation between the plate 2 of the ski 1 and the lower element 32 of the fixing device 31 could be symmetrically reversed, the light being on the latch of the fixing device and a guide finger on the plate. Alternatively, the movable lock could be on the plate. In the example shown, the plate 2 on the ski is provided with a longitudinal adjustment mechanism, linked to the rear plate, to obtain a simultaneous adjustment of the positioning of these plates and therefore the fastening device to accommodate different size shoes. However, the solution according to the invention can be applied to any other configuration of longitudinal adjustment of the binding. In particular, the movements of the rear plates 2 'and before 2 could be decorrelated. A plate could even be fixed on the ski, possibly integrated into the structure of the ski itself and no longer in the form of a separate plate attached to the ski.

  Similarly, the lower element 32 of the shoe attachment device can be in the form of a separate element and added under an existing device, as an adapter for the implementation of the solution. In such a case, this element may possibly fulfill a booster function to adjust the height of the fixing device. According to another variant, this lower element may be an integrated part of the device, not dissociating itself from the rest of the device.

  This solution thus makes it possible to respond to the objects of the invention and to offer the following advantages: it is simple and user-friendly since the fixing device is automatically fixed; it is inexpensive because of its simplicity.
