    BRAKING DEVICE FOR FIXING A SLIDING BOARD
    The present invention relates to a braking device for fixing a gliding board such as a ski. The invention is more particularly intended for a mixed use of the gliding board, namely, a use for an alpine type practice and use for a hiking type of practice. In the first case, the brake must be continuously operational so that it can activate and stop the movement of the ski as soon as the skier triggers or loosens the binding. In the second case, the brake must be inhibited so that the brake remains inactive, when the skier raises the heel of his shoe, so as not to slow down his movement.
    In known manner, the braking devices comprise two lateral braking branches. Each branch pivots around an axis transverse to the ski. Elastic means tend to maintain the branches in an active braking position, in which the branches are sufficiently inclined relative to the sole of the ski so that a portion protrudes from the sole of the ski, downwards, to catch the snow. To inhibit the brake, it is sufficient to rotate the brake arms so as to raise the part, likely to hang the snow, above the sole of the ski. The branches are then in a sliding position.
    In practice alpine style, the branches are held in the sliding position by the heel of the shoe, when it is engaged with the binding.
    In a hiking type of practice, the shoe pivots about a transverse axis positioned at the front of the shoe. As a result, as soon as the skier raises the heel, he releases the brake. To avoid braking the ski at each step, it is necessary to provide a device for locking the brake in an inactive configuration in which the branches are held in a sliding position.
    For this, many documents describe braking devices provided with a lock for maintaining the branches in a sliding position. Such constructions are illustrated, for example, in EP 2 259 850, WO 2012/024809 or EP 2 666 525.
    All these constructions are characterized by a piece blocking the rotation of the branches to keep them in a sliding position. In these solutions, an elastic means exerts a force on the branches so as to rotate them only in a direction of rotation. This means that the locked brake configuration is an unstable position that is held only by the lock. Thus, the lock is continuously solicited when it blocks the branches. The lock must be dimensioned accordingly.
    The object of the invention is to provide an improved braking device.
    One goal is to provide a reliable and secure braking device.
    Another object is to reduce the number of components constituting the braking device. The invention proposes an article a braking device for gliding board, comprising: a base adapted to be secured to the gliding board, at least one braking branch capable of pivoting, with respect to the base, around a first axis of rotation substantially transverse to the gliding board, the braking branch comprising a control element extending along an axis substantially parallel to the first axis of rotation, a bearing plate movable relative to the base, the plate with a guide housing of the control element, the position of the control element in the guide housing varying according to the angular position of the brake arm, an elastic means acting on the control in a direction of actuation varying according to the angular position of the braking branch. The article is characterized by the fact that the support plate is designed to move with an amplitude covering at least two positioning ranges: a first positioning range for which the base, the braking arm, the plate support and the resilient means are arranged so that the elastic means acts on the control element so as to cause the rotation of the brake arm in a first direction and a second positioning range for which the base, the braking branch, the support plate and the elastic means are arranged so that the elastic means acts on the control element so as to cause the rotation of the braking branch in a second direction, which is the opposite of the first direction of rotation .
    Thanks to the invention, the device can rotate the branches alternately in one direction or in the opposite direction. This makes it possible to provide two stable positions for the braking arm or branches: an active braking position (in one direction) and a sliding position (in the other direction). This construction does not require an additional locking piece which simplifies the design. Moreover, the absence of additional locking piece intended to keep the device in an unstable position makes it possible to reinforce the reliability of the mechanism. This one then alternates between two stable configurations. The locking of branches in sliding position is secure. Indeed, in conventional constructions, if the lock breaks, the branches automatically switch to an active braking position. In the proposed construction, there is no need for a lock. On the other hand, the component parts are not very solicited, the dimensioning can be optimized.
    According to advantageous but non-obligatory aspects of the invention, such a braking device may incorporate one or more of the following features, taken in any technically permissible combination:
    The support plate is pivotable relative to the base around a second axis of rotation substantially parallel to the first axis of rotation.
    The braking device includes a latch that can be tilted into an abutment configuration for which the latch is able to interact with the backing plate so as to limit its rotation so that it can only remain in its first positioning range.
    The braking device includes a first actuator that can interact with the backing plate to cause rotation of the backing plate to tilt from its first positioning range to its second positioning range.
    The braking device includes a second actuator that can interact with the backing plate to cause rotation of the backing plate to tilt from its second positioning range to its first positioning range.
    The latch, the first actuator and the second actuator form a single piece.
    The part forming the latch, the first actuator and the second actuator pivots, relative to the base, about a third axis of rotation substantially parallel to the second axis of rotation.
    The braking device comprises a retractable wedge capable of interacting with a heel of a shoe so as to limit the vertical displacement of the heel in the direction of the gliding board so that the heel can not cooperate with a fastener element. a heel piece attached to the gliding board.
    The braking device comprises a holding means for holding the support plate in its second positioning range.
    The holding means is formed by an interaction between a bearing plate member and an actuating lever member, the actuating lever moving in a direction distinct from that of the bearing plate. Other features and advantages of the invention will be better understood with the aid of the following description, with reference to the accompanying drawings illustrating, according to non-limiting embodiments, how the invention can be realized, and in which : Figure 1 is a front perspective view of a ski equipped with a heel and a braking device according to the invention, in braking configuration; Figure 2 is a front perspective view of the ski equipped with Figure 1, the braking device being locked in slip configuration; Figure 3 is an exploded perspective view of the braking device; Figure 4 is a top view of the braking device; FIGS. 5 and 6 are sectional views along A-A of FIG. 4 respectively illustrating the braking device in the braking configuration and the braking device in the locked slip configuration; Figures 7 and 8 are sectional views along B-B of Figure 4 respectively showing the braking device in braking configuration and the braking device in locked slip configuration; Figures 9, 10, 11 and 12 are cross-sectional views along C-C of Figure 4 illustrating the different steps of switching the braking device from a braking configuration to a locked slide configuration; Figure 13 is a sectional view along C-C of Figure 4 illustrating a tilting step of the braking device of a locked slide configuration to a braking configuration; Figure 14 is a sectional view along D-D of Figure 4 illustrating the braking device in locked slip configuration; Figure 15 is a sectional view along C-C of Figure 4 illustrating the braking device in unlocked configuration gliding; Figure 16 is a rear view of a shoe resting on the braking device locked in slip configuration. The invention is illustrated through an embodiment shown in Figures 1 to 15. It relates to a braking device 1 assembled on a gliding device 2, for example, a ski. In this case, the braking device is associated with a fastening of a boot 4 on the ski. The attachment comprises a front retainer, called "stop", not shown, and a rear retainer 3, called "heel", illustrated in Figures 1 and 2. The front and rear retainers are intended to secure respectively the front and back of the shoe with the gliding machine. In downhill configuration, the two retainers cooperate with the boot. In climbing configuration, only the front retainer cooperates with the boot.
    In the rest of the description, terms such as "horizontal", "vertical", "longitudinal", "transversal", "superior", "lower", "up", "down", "before" will be used. , " back ". These terms must in fact be interpreted in a relative manner in relation to the normal position that the braking device occupies on a ski, and the normal direction of advancement of the ski. For example, "longitudinal" refers to the longitudinal axis of the ski.
    A mark will also be used whose longitudinal or front / rear direction corresponds to the X axis, the transverse or right / left direction corresponds to the Y axis and the vertical direction or up / down direction corresponds to the Z axis.
    The braking device 1 comprises a base 10 provided to be secured to the gliding board. Thus, when the base is assembled on the ski, the base is fixed relative to the ski. In this example, the base is fixed directly on the upper face 21 of the gliding board 2. Alternatively, the base can be slidably mounted longitudinally relative to the ski, to allow the longitudinal adjustment of its position. Once adjusted, the base is then immobilized longitudinally to make it integral with the ski. In a variant, the base is fixed on the body of the heel piece 3.
    In this embodiment, the braking device 1 also comprises two braking branches 11a, 11b, arranged symmetrically with respect to the longitudinal median plane XZ of the ski. The two braking branches 11a, 11b having identical operation, only a branch 11a will be described. The other braking branch 11b is composed of similar elements. It is arranged symmetrically with respect to the median vertical plane XZ.
    The braking branch 11a comprises a central cylindrical portion 111, extending along an axis of revolution Y111. On one side, at its outer end, the central portion 111 is extended by a cylindrical outer portion 112, in a first direction substantially perpendicular to the axis Y111. On the other side, at its median end, the central portion 111 is extended by a cylindrical inner portion 113, in a second direction substantially perpendicular to the axis Y111. This second direction is opposed to the first direction. The first and second directions are substantially parallel. The inner portion 113 is bent. It is thus continued by a cylindrical control portion 114, extending along an axis of revolution Y114, substantially parallel to the axis Y111 and distant by a length d11 of this axis Y111. This control portion 114 will be called "control element" thereafter. The four portions 111, 112, 113 and 114 constituting the braking branch 11a are combined without the same plane. In other words, the braking arm forms a "W" at right angles.
    The braking branch 11a is assembled to the base 10 at its central portion 111 by a pivot type connection. The base 10 thus comprises a lateral bearing 101 having an axis of revolution Y101, substantially transverse to the ski. This bearing makes it possible to guide the braking arm in rotation about its axis Y111. When the brake is assembled, the axis of revolution Y111 of the central portion and the axis of revolution Y101 of the bearing are substantially coincidental and define a first axis of rotation Y11 of the braking branch. To achieve the lateral bearing 101, the base may comprise two parts to facilitate assembly of the braking branch.
    The braking branch 11a and the base 10 are arranged relative to the ski so that the lateral position (Y) of the outer portion 112 is spaced from the lateral edge of the ski. Thus, when the braking arm rotates about its axis Y11, in a first direction S1, the outer portion 112 tilts so that its free end protrudes from the sole 22 of the ski, downwards, to hang the snow. This configuration of the braking device is designated as a braking configuration. The movement is stopped or, at least braked, by the portion of the outer portion 112 projecting from the sole and interacting with the snow. To improve the grip, the free end is generally equipped with a tip 115. On the other hand, when the braking arm rotates about its axis Y11, in a second direction S2, inverse to the first direction S1, the portion 112 exterior returns to a position set back, upwards, with respect to the sole 22 of the ski. In this configuration of the braking device, said gliding configuration, no part of the braking branch protrudes from the sole 22 of the ski. The braking device does not interfere with the movement of the ski.
    To rotate the braking arm, use is made of the inner part of the braking arm and more particularly the control element 114. Being oriented substantially parallel to the axis Y11 and at a distance d11 thereof, the control element 114 controls the rotation of the brake arm. Thus, the control element can move in a circular arc, centered on the axis of rotation Y11.
    To control the movement of the control element 114, the braking device comprises a support plate 12, pivotally mounted relative to the base 10, about a second axis of rotation Y12. The base 10 comprises bearings 102 for rotating the support plate 12 to rotate. The second axis of rotation Y12 is substantially parallel to the first axis of rotation Y11 and offset towards the front of the base. The support plate 12 comprises an upper surface 121 adapted to come into contact with a sole 41 of the ski boot 4. On each lateral side, the support plate comprises a guide housing 122 of the control element 114 a braking branch 11a, 11b. This guide housing 122 is in the form of an oblong opening extending in a direction X122. The guide housing is delimited longitudinally by a front face 1221 and a rear face 1222. The height of the guide housing is slightly greater than the diameter of the control element 114. The control element 114 is designed to fit into the guide housing 122 and to move along the oblong hole. Consequently, when the support plate 12 rotates about its axis of rotation Y12, this causes the displacement of the control element 114 in its guide housing 122, which results in the rotation of the braking arm 11a, 11b associated around its axis of rotation Y11.
    The braking device can take several configurations.
    A first extreme configuration, called braking, is illustrated in FIGS. 1, 5, 7 and 9. The support plate 12 is raised until the control element 114 abuts against the rear face 1222 of the guide housing. 122. In this case, the braking branch 11a can no longer rotate further in the first direction S1. The end of the outer portion 112 protrudes from the sole and is able to catch the snow. In this configuration, the axis of revolution Y114 of the control element is positioned above the plane defined by the first axis of rotation Y11 and the second axis of rotation Y12. The angle α between the plane of the braking branch and the upper surface 121 is less than 90 degrees and preferably less than 60 degrees, to facilitate the rotation of the support plate without being impeded by the braking branch.
    When the support plate 12 is pressed, the control element 114 is actuated via the guide housing 122. Thus, the guide element translates longitudinally inside the housing, which results in the rotation of the braking branch about its axis Y11, in the direction S2. The braking device then reaches a tilting configuration in which the first axis of rotation Y11, the second axis of rotation Y12 and the axis of revolution Y114 of the control element are aligned in the same plane. In this example, they are aligned in the same plane as the plane of the braking branch. This tilting configuration is illustrated in FIGS. 11 and 13. The guide member 114 has reached an extreme position in its guide housing. To achieve this tilting configuration, it is necessary that the front face 1221 of the guide housing is sufficiently spaced from the rear face 1222 so as not to interfere with the displacement of the guide element.
    When the rotation of the support plate 12 is continued, the control element 114 returns towards the rear face 1222, inside its guide housing 122. However, the rotation of the support plate is limited by stubborn. In this example, as seen in FIG. 6, a lower abutment surface 123 comes into contact with a part of the braking branch, in this case the internal portion 113. Alternatively, the plate can come into abutment against a layout of the base. When the support plate is in abutment, the outer portion 112 of the brake arm is raised above the upper face 21 of the ski. No more element of the brake disturbs the glide of the ski. In this case, the braking branch 11a can no longer rotate further in the second direction S2. This second extreme configuration, illustrated in FIGS. 2, 6, 8 and 12, corresponds to the locking configuration of the braking device. In this configuration, the axis of revolution Y114 of the control element is positioned below the plane defined by the first axis of rotation Y11 and the second axis of rotation Y12.
    The term braking configuration of the braking device, a configuration for which the outer portion 112 is sufficiently raised to no longer protrude from the sole 22 of the ski and therefore no longer slow the movement of the ski. As a result, the lock configuration, described above, is a first glide configuration.
    To ensure the operation of the brake, the device comprises an elastic means 13 acting on the control element 114 so as to return it to a defined position of the guide housing 122. In this example, the elastic means is a tension spring of which one end is fixed on a shaft 124, supported by the support plate 12, at its rear end, and whose other end is fixed on a connecting piece 14 connecting the control element of a braking branch 11a to the control element of the other braking branch 11b. The spring is centered laterally with respect to the backing plate. The spring is dimensioned so that it is in tension when the braking device is in its braking configuration, as illustrated in FIG. 7. The spring acts on the control element in a varying direction of operation X13. the angular position of the braking branch (in the fixed XYZ reference linked to the ski). The spring 13, the shaft 124 and the connecting piece 14 are arranged so that the elastic means 13 tends to bring the control member 114 back to the rear face 1222 of the guide housing 122, regardless of the configuration of the device braking.
    This elastic means 13 thus allows the braking device to have two stable configurations.
    The first stable configuration of the braking device corresponds to the braking configuration described above and represented in FIG. 7.
    When the bearing plate pivots in a first positioning range, placing the braking device in a configuration between this braking configuration and the previously described tilt configuration, a first unstable configuration of the braking device is obtained. As soon as the support plate is released, the elastic means 13 brings the device back to its first stable configuration. The elastic means 13 thus acts on the control element 114 so as to cause the rotation of the braking arm in a first direction S1 until the control element comes into abutment against the rear face 1222 of its housing. This first unstable configuration range of the braking device thus defines the first positioning range of the support plate.
    When the bearing plate pivots more than before, in a second positioning range, so as to place the braking device in a configuration beyond the failover configuration and up to the locking configuration described above, one obtains also a second unstable configuration of the braking device. However, in this range of rotation of the plate, the elastic means 13 tends to bring the device back into its second stable configuration. The elastic means 13 thus acts on the control element 114 so as to cause the rotation of the braking arm in a second direction S2, which is the opposite of the first direction of rotation S1, until the control element arrives stop against an element of the device. In this example, the control element bears on the inner portion 113 of the braking branches. This second unstable configuration range of the braking device defines the second positioning range of the support plate.
    The second stable configuration of the braking device corresponds to the locking configuration shown in FIG.
    In the conventional brake constructions of the prior art, the devices are designed for a single unstable configuration range. The backing plate always remains in its first positioning range and never reaches a position placing the device in its tilt configuration. The elastic means only makes it possible to cause the rotation of the braking branch in only one direction S1. There is therefore only one stable position corresponding to the braking position. In these solutions, the brake is locked in an unstable configuration. If the lock fails, the brake switches to its unique stable braking configuration.
    According to the invention, the support plate is designed to move an amplitude covering at least the two positioning ranges defined above. For the first positioning range of the support plate, the base, the braking leg, the support plate and the elastic means are arranged so that the elastic means acts on the control element so as to cause the rotation of the braking branch in a first direction S1. For the second range of positioning of the bearing area, the base, the braking leg, the support plate and the elastic means are arranged so that the elastic means acts on the control element so as to cause the rotation of the braking branch in a second direction S2, opposite to the first direction of rotation. This characteristic thus makes it possible to obtain the two stable configurations described above.
    In the embodiment, the elastic means is a tension spring. Other types of elastic means can be envisaged. For example, it may be springs working in compression. In this case, the springs are placed at the front of the support plate, between the second axis of rotation Y12 of the support plate and the axis of revolution Y114 of the control element. It is also possible to use two springs, mounted in parallel, and arranged symmetrically with respect to a vertical median plane XZ of the support plate. The elastic means may be a part having suitable elastic properties. Moreover, the connecting piece 14 is optional, the elastic means being directly connectable to one or both control elements 114.
    According to one embodiment, the traction means 13 acts on the control element 114 in a direction X13 extending in a plane passing through the second axis of rotation Y12 of the support plate and by the axis of revolution. Y114 of the control element 114 when housed in its guide housing 122. This construction makes it possible to reduce the parasitic friction during the displacement of the control element 114 in its guide housing 122.
    In this example, the braking device comprises an actuating lever 15 for configuring the device.
    The actuating lever 15 pivots, relative to the base, around a third hinge axis Y15, substantially parallel to the second hinge axis Y12 of the support plate and offset towards the rear of the base. This third hinge axis Y15 is positioned between the first hinge axis Y11 and the second hinge axis Y12. The base 10 comprises bearings 103 for guiding in rotation the operating lever 15. The operating lever 15 is in the form of a "U" comprising two lateral branches 151a, 151b connected by a transverse bar 152 The third hinge axis Y15 passes through the free end of the lateral branches 151a, 151b of the "U" profile. At each of these ends, the actuating lever 15 comprises an extension 153, extending transversely, towards the other end. This extension 153 supports a cam surface 154 surrounding the extension. This cam surface 154 is arranged such that when the braking device is assembled, the cam surface 154 is positioned opposite a lower contact surface 125 of the backing plate 12.
    We will now describe the switching of the device from a braking configuration to a locking configuration.
    The locking of the brake is obtained by the tilting back of the actuating lever 15.
    In the first configuration of the braking device, called braking, the lever is tilted forward until it abuts against the ski or the base. This configuration is illustrated in FIGS. 9, 1, 5, 7 and 14. In this case, the cam surface 154 is able to interact with the lower contact surface 125 so as to limit the rotation of the support plate 12 so that it can only stay in its first positioning range. The backing plate can not reach a position placing the device in its tilt configuration. The cam surface 154 acts as a latch that has tilted into an abutment configuration. The device is in a classic alpine skiing configuration. When the heel 42 of the shoe 4 presses on the upper surface 121 of the support plate 12, this causes the rotation of the support plate and, consequently, the rotation of the braking branches 11a, 11b until that the outer portion 112 is raised enough to no longer project downwardly from the sole 22 of the ski 2. The braking device is in a second sliding configuration, as shown in Figure 15. This position of the heel 42 is held by the heel 3. When the heel is triggered, the shoe disengages from the binding, the heel moves away from the support plate. The spring 13 acts on the braking branches 11a, 11b to return them to a first position where they will interact with the snow. The braking device is then in its first stable configuration corresponding to the braking configuration.
    When turning the actuating lever 15, to tilt it backwards, it bears against the upper surface 121 of the support plate, as seen in FIG.
    When the rotation of the operating lever 15 is continued, this causes rotation of the support plate 12 to a position placing the device in its tilting configuration, as seen in FIG. The backing plate can achieve this positioning because rotation of the operating lever 15 has caused rotation of the cam surface 154 which is no longer able to interfere with the lower contact surface 125. The actuating lever acts as a first actuator operable to interact with the backing plate to cause rotation of the backing plate to tilt from its first positioning range to its second positioning range.
    By continuing the rotation of the operating lever 15, the support plate 12 switches to an unstable position. The spring 13 then acts on the braking branches 11a, 11b to return them to a second position where they are set back relative to the upper face 21 of the ski 2. The support plate 12 will automatically continue to rotate until abut against an element 113 of the braking device. In this case, the actuating lever 15 is no longer in contact with the support plate 12. The braking device is then in its second stable configuration corresponding to the locking configuration which is illustrated in FIGS. 12, 2 , 6 and 8.
    To arm the braking device, that is to say, make it active, it is necessary to tilt the actuating lever 15 forward. Indeed, when the operating lever is turned to fold it back to the before, the lever reaches an angular position for which the cam surface 154 comes into contact with the lower contact surface 125 of the backing plate. If the rotation of the actuating lever is continued, the cam surface causes rotation of the backing plate until the braking device reaches its tilt configuration, as shown in FIG. 13. continuing slightly the rotation of the lever, it brings the support plate in an unstable position corresponding to the first unstable range of the braking device. The spring 13 acts on the braking branches 11a, 11b to return them to a first position where they will interact with the snow. The support plate 12 will automatically continue its rotation until the control element 114 abuts against the rear face 1222 of its guide housing 122. The braking device then returns to its first stable configuration corresponding to the configuration of the braking. The brake is armed. The actuating lever acts as a second actuator that can interact with the backing plate to cause rotation of the backing plate to tilt from its second positioning range to its first positioning range.
    Advantageously, when the braking device is in its locking configuration, the actuating lever 15 has tilted backwards and bears against the base 10 or a part of the ski. In this configuration, the actuating lever 15 has a bearing surface 155 oriented, upwards, on which the sole of the shoe can come to rest, at the heel. This bearing surface 155 is remote from the upper face 21 of the ski so that, when the boot is resting on the actuating lever, the shoe is slightly inclined forwardly in order to improve the support on the ski during the ascension phases. The operating lever thus acts as a conventional climbing wedge. Preferably, with this arrangement, the bearing surface 155 is positioned so that, when the heel in contact with the actuating lever, the shoe 4 can not cooperate with a fastening element 31 of the heel piece 3. In this example, the heel 3 comprises two rods 31 corresponding to the fixing element described above. Each free end of these rods is intended to be guided in a guide path formed in the rear face of the heel until it is positioned in a housing 43. Once the free end of the rods 31 is positioned in this housing 43 , the heel is engaged. The shoe is engaged with the heel that prevents vertical movement up the heel as the vertical force exerted by the heel remains below a trigger threshold. When the actuating lever 15 has tilted backwards, the bearing surface 155 blocks the downward vertical movement of the bead 42 so that the free ends of the rods 31 can not be positioned in their respective housing 43 of the heel 42 of the shoe 4. This configuration is illustrated in Figure 16. According to another embodiment, the heel attachment element is a jaw rotatably mounted about a transverse axis. In all cases, the actuating lever 15 acts as a retractable wedge capable of interacting with a heel 42 of a boot 4 so as to limit the vertical displacement of the heel towards the gliding board so that the heel can not move. not engage with a fastener 31 of a heel 3 secured to the gliding board.
    Thus, when the braking device is in a locking configuration or a first gliding configuration, the boot 4 can not be in engagement with the heel piece 3. This specificity brings a safety of use because it assures us that the user can not engage the heel when the braking device is in lock configuration. Therefore, when he wants to practice alpine skiing, he can not engage the fixation only when the brake is active or armed.
    According to one embodiment, the actuating lever comprises indexing means relative to the base for holding the actuating lever in one or more stable positions. For example, the position of the lever completely folded forward, this position corresponds to the braking configuration of the braking device. It can also be the position of the lever completely folded backwards, this position corresponds to the locking configuration of the braking device. Between the stable positions, it can provide an energization of the actuating lever so that it switches to a close stable position when it is in an intermediate position. The indexing can be performed, for example, by a deformable pin cooperating with a complementary housing. Ramps can also be added to bring energization. Energization can also be achieved by an elastic means.
    To avoid unintentional unlocking of the braking device, it may comprise a holding means for maintaining the braking device in its second unstable configuration range. Unintentional unlocking can, for example, occur by an action on the braking limbs, in particular by pressing down on the folded external portions. To maintain this locking configuration, it is important to limit the rotation of the support plate so that it remains in its second positioning range, in other words, it does not reach a position placing the device in its configuration. failover. The holding means may be fastening means between the actuating lever and the base. It can be clips, magnets, a movable lock ... In a variant, the holding means can be fastening means between the support plate and the base. It can be clips, magnets, a movable lock ... Alternatively, the holding means can be means of attachment between the actuating lever and the support plate. Again, it may be clips, magnets or a form interacting with a complementary shape due to the relative kinematics between these two parts, they do not rotate around the same axis of rotation. It is also possible to envisage a holding means acting directly on the braking limbs so as to limit their rotation. The holding means can be actuated directly by the user or via an intermediate piece, such as, for example, the operating lever 15.
    In the example illustrated, in particular in Figure 14, the support plate 12 comprises lateral lugs 126, projecting in a transverse direction, outwardly. These lateral lugs are intended to cooperate respectively with notches 156 formed in the inner face of the lateral branches 151a, 151b. When the support plate 12 has tilted to a stable position corresponding to the locking configuration of the braking device, the operating lever can easily tilt into its rear position because the notches 156 are dimensioned to receive the lateral pins 126, without interference. However, the dimensioning of the notches 156 is such that when the bearing plate is rotated forwards, the lugs 126 cooperate with the notches 156 so as to jam, which makes it possible to block the rotation of the plate. support for it to stay in its second positioning range. This construction makes it possible to have a self-locking locking of the braking limbs. Indeed, the operation is irreversible. Thus, one can act freely on the operating lever in one direction and cause the rotation of the support plate in the same direction. One can also act freely on the operating lever in the other direction. However, when acting on the support plate in the other direction, the rotation thereof is blocked by the holding means. And, in this case, the more one forces the rotation of the support plate in the other direction, the more one blocks the kinematics. Thus, the holding means is formed by an interaction between an element of the support plate 12, namely the lugs 126, and a member of an actuating lever 15, namely the notches 156. To obtain the self-locking, the actuating lever moves in a direction distinct from that of the support plate. Here, the axis of rotation Y15 of the operating lever is distinct from that Y12 of the support plate. Alternatively, the support plate can be translated. In this case, the actuating lever must not translate in the same direction as the translation of the support plate. It can be envisaged that the support plate and the actuating lever have distinct movements. One turns while the other is translated.
    In the illustrated embodiment, we have seen that the actuating lever 15 has several functionalities. It can act as a lock, a first actuator, a second actuator and a shim. Alternatively, each of these functions can be performed by a separate, separate piece. Similarly, the same room can perform one, two or three of the aforementioned functions.
    In the description, the braking device has a simple conventional brake structure. This choice has essentially simplified the description. It is understood that the invention also extends to other types of brake. For example, the invention is particularly well suited to a so-called reentrant brake structure such as that illustrated in documents EP 0 025 786 or EP 1 731 202. The re-entrant brakes are characterized by the fact that the external portions of the braking limbs offset laterally, when the braking device is in a gliding configuration, to be positioned above the upper face of the ski. In this case, the connection between the braking arm and the base may be of sliding pivot type rather than pivot type. The braking branch can pivot about the axis of rotation Y11 and / or translate laterally with respect to this axis. Guide ramps are provided in the component parts of the brake to cooperate with a portion of the braking limbs to allow the desired kinematics. In another variant, the connection between the braking arm and the base is of the ball type, possibly with the possibility of moving the braking arm transversely.
    In the description, reference is made to a notion of "substantially" to characterize the element arrangement with respect to a reference frame: an axis or element being "substantially" parallel, perpendicular or transverse. This notion means that the orientation can vary by an angle of plus or minus 30 degrees. For example, with a so-called re-entrant brake, the kinematics of the brake arms is complex, which means that the braking arms do not necessarily rotate, and all the time, around a transverse axis. Similarly, the braking branches may comprise portions arranged differently, with a specific angle between these portions. Therefore, it is desirable to introduce a tolerance in this arrangement feature to cover construction variants of the same inventive concept.
    In this example, the support plate 12 is a pivoting part. Alternatively, the support plate may have another kinematics. It can have a translation movement or a combination of translation and rotation. The invention is not limited to these embodiments. It is possible to combine these embodiments. The invention is not limited to the previously described embodiments but extends to all the embodiments covered by the appended claims.
