Definitions

  • the present invention relates to a braking device for a binding for a gliding board, such as a ski or a monoski.
  • a ski binding includes a front portion, engaged by the front of a ski boot, and a rear portion, engaged by the heel. Vertical pressure engages the heel of the boot into the rear portion of the binding, which then retains the boot.
  • the rear portion of the ski binding generally incorporates a braking device comprising two lateral braking arms.
  • a return mechanism tends to maintain the arms in an active braking position, in which the arms are inclined in relation to the sliding surface of the ski, or ski sole, and extending downward from the ski to engage the ground or snow.
  • the arms rise above the ski sole, in a gliding position.
  • the braking arms In this gliding position, the braking arms should not be spaced too far apart from the longitudinal edges of the ski, in order not to interfere with the gliding of the ski. Indeed, the ski tilts in curves and the braking arm located inside the curvature can come into contact with the snow, thereby slowing the ski. Therefore, the braking devices often incorporate a mechanism which, in the gliding position, brings the ends of the arms closer to one another, above the ski and in the direction of the longitudinal median plane of the ski.
  • skis vary from one model to another, particularly in the central portion of the ski, on which the binding incorporating the braking device is mounted. Similarly, for the same ski model, the ski width can vary depending upon its length. Therefore, ski manufacturers must provide braking devices of various widths, adapted to each ski model and length, which is expensive and makes it difficult to manage stocks, for ski manufacturers, retailers and renters alike.
  • EP 1 731 202 A1 discloses a braking device of adjustable width solving the aforementioned problem, in which the unitary, single-piece braking arms are each connected to a notched adjusting element that cooperates with a base of the braking device. Due to the notched adjusting elements, the distance between the arms is adjustable, thereby making it possible to mount the braking device on skis of various widths.
  • This document describes a first embodiment in which the notched adjusting elements move in lateral translation.
  • the relative angle between the two adjusting elements has a direct influence on the relative angle between the two braking arms, because the arms are connected to the adjusting elements.
  • the two adjusting elements By rotating about the same central vertical axis, the two adjusting elements define a relatively large opening angle, regardless of the width of the ski. This translates into an equally large opening angle of the two braking arms.
  • the larger the opening angle of the two braking arms the greater the spacing of the ends of the arms, in the braking position.
  • the opening angle of the braking is relatively large.
  • This alternative embodiment has several drawbacks due to the rotation of the adjusting elements about the same vertical axis. Indeed, the opening angle of the braking arms hinders the storage, sole-against-sole, of the skis, because the braking arms, when defining a large opening angle, do not properly maintain the skis against one another, in relation to arms oriented parallel to the ski.
  • the ski equipped with this braking device is relatively bulky transversely, that is to say, perpendicular to the length of the ski. Furthermore, the lateral protrusion of the ends of the arms can cause injuries.
  • the kinematics about a single central axis involves a taxing space requirement of the braking device: the device is thick, as the two adjusting elements are caused to overlap one another in a direction perpendicular to the ski. This overlap causes friction which results in wear on the adjusting elements.
  • the device must also be long and wide due to the kinematics requiring a large range of movement to enable the arms to extend around the longitudinal edges of the ski.
  • the braking characteristics can vary significantly between two extreme width adjustment configurations of the device.
  • the present invention more particularly overcomes the aforementioned drawbacks.
  • the invention provides a braking device for gliding board of adjustable width, which is compact and easy to handle.
  • the invention further provides a braking device having a small opening angle for the braking arms in the braking position. This makes it possible to have relatively consistent braking characteristics, irrespective of the adjustment of the spacing of the braking arms.
  • the invention provides a braking device for gliding board, comprising:
  • the flanges are rotationally movable in relation to the plate, about axes of rotation that are separate from one another.
  • the spacing of the braking arms is achieved by adjusting the angular spacing of each flange about a distinct axis of rotation, that is to say that the axes of rotation are not aligned.
  • Each flange thus has its own axis of rotation, which substantially reduces the space requirement of the device.
  • the overlap of the flanges is thus avoided, thereby reducing the thickness of the device.
  • the opening angle between the distal portions of the arms is reduced.
  • the braking device of the invention is thus adaptable to gliding boards of various widths, while optimizing the braking characteristics, regardless of the spacing position of the arms.
  • such a braking device can incorporate one or more of the following characteristics, taken in any technically permissible combination:
  • the spacing of the braking arms is achieved by adjusting the angular spacing of the blades using the assembly element. Adjusting the spacing of the arms is easy and intuitive.
  • FIG. 1 is an exploded perspective view of a braking device according to the invention
  • FIGS. 2 and 3 are side views of the device of FIG. 1 , in the braking position and the gliding position, respectively;
  • FIGS. 4 and 5 are top and bottom views of the device of FIG. 1 , in a minimum spacing configuration of the braking arms of the device, and
  • FIGS. 6 and 7 are bottom views of the device of FIG. 1 , in the intermediate and the maximum spacing configurations, respectively, of the braking arms.
  • FIGS. 1-7 illustrate a braking device 1 comprising a plate 2 fixed to a ski 10 shown partially, two flanges 3 a and 3 b rotationally movable in relation to the plate 2 , two braking arms 4 a and 4 b mounted to freely translate transversely and rotate on the flanges 3 a and 3 b , a heel piece 8 for supporting the heel of a ski boot, not shown, and a conventional drive device 9 for actuating of the device 1 .
  • the device 1 is symmetrical with respect to a longitudinal median plane P of the ski 10 .
  • the elements designated by a reference numeral followed by the character “a” are located in the background of FIG. 1 , in relation to the plane P, that is to say, toward the flange 3 a and the braking arm 4 a .
  • the elements designated by a reference numeral followed by the character “b” are located on the other side of the plane P, that is to say, in the foreground of FIG. 1 , in relation to the plane P, toward the flange 3 b and the braking arm 4 b.
  • the ski 10 is demarcated by an upper surface 11 , on which the braking device 1 is to be fixed, and by a sole 12 , including a gliding surface, opposite the upper surface 11 and in contact with the snow during use of the ski 10 .
  • the lateral surfaces 13 of the ski 10 extend upwardly and can be generally parallel to the plane P. When the ski 10 is parabolic, the surfaces 13 are slightly curved.
  • the plate 2 and heel piece 8 are stationary in relation to the ski 10 .
  • screws not shown, can be used to fix the heel piece 8 to the plate 2 and the plate 2 to the ski 10 .
  • the description takes into account that the terms “upper”, “above,” and “top” refer to a direction Z-Z′ perpendicular to the upper surface 11 of the ski 10 and extending from the sole 12 to the upper surface 11 , that is to say, a direction towards the upper portion of FIGS. 1 to 3 , whereas the terms “lower”, “below,” and “bottom” refer to an opposite direction.
  • the sole 12 of the ski 10 is laid on a horizontal flat surface, the axis Z-Z′ is vertical and the upper elements are higher than the lower elements.
  • the two flanges 3 a and 3 b form flat, thin blades that are parallel to the upper surface 11 of the ski.
  • the term “thin” is intended to refer to a thickness at least five times less than the width of the blade.
  • the term “blades” designates the flanges 3 a and 3 b .
  • the flanges are not necessarily flat blades. The advantage of using thin blades is mainly to reduce the space requirement and, more particularly, to significantly reduce the thickness of the device along the direction Z-Z′.
  • longitudinal is used to designate a direction substantially parallel to the length of the ski 10
  • transverse is used to designate a direction substantially perpendicular to the longitudinal direction; in other words, along the direction of the width of the ski 10 .
  • proximal designates the elements of the arms 4 a and 4 b that are closer to the drive device 9 . These elements therefore correspond to the “upper” elements of the arms 4 a and 4 b . Conversely, the “distal” elements are closer to an end 49 of the arms 4 a and 4 b adapted to engage the snow in the braking position. These elements therefore correspond to the “lower” elements of the arms 4 a and 4 b.
  • Two longitudinal lateral slots 21 a and 21 b are provided in the plate 2 and are separated by a central strip 22 parallel to and centered on the plane P.
  • the strip 22 is slightly raised in relation to the remainder of the plate 2 , and a projecting pin 23 extends downward from the central strip 22 towards the ski 10 , along a vertical direction, i.e., along a direction perpendicular to the upper surface 11 of the ski when the plate is fixed to the ski.
  • the arms 4 a and 4 b are symmetrical to one another, in relation to the plane P.
  • the arms each comprise a cylindrical metal rod 43 , and an anchoring element 42 , made of a plastic material are fitted to the distal end 49 of the rod 43 .
  • the arms 4 a and 4 b are movable in relation to the blades 3 a and 3 b , between a braking position, shown in FIG. 2 , and a gliding position, shown in FIG. 3 .
  • the arms 4 a and 4 b each include a distal braking portion 41 , which is anchored in the snow when the device 1 is in the braking position, an angled drive portion 45 cooperating with the drive device 9 , and a rectilinear and transverse connecting portion 44 connecting the portions 41 and 45 .
  • each arm 4 a and 4 b is guided by a blade 3 a or 3 b .
  • the connecting portion 44 is mounted in a housing 340 a or 340 b of the corresponding blade 3 a or 3 b , which extends along an axis A 34 a or A 34 b .
  • the axes A 34 a and A 34 b extend along a transverse, or even substantially transverse, direction depending upon the adjustment of the spacing of the braking arms 4 a and 4 b.
  • the housings 340 a and 340 b are sized to permit rotation of the arms 4 a and 4 b about the axes A 34 a and A 34 b , and transverse translation of the arms 4 a and 4 b in relation to the blades 3 a and 3 b , that is to say, translation along the direction of the axes A 34 a and A 34 b.
  • the drive portion 45 of each arm 4 a and 4 b is located between the side surfaces 13 of the ski 10 , and the braking portion 41 projects partially outside of the ski 10 , beyond the surface 13 .
  • the proximal end of the drive portion 45 of each arm 4 a and 4 b forms the proximal end 48 of the braking arm 4 a or 4 b and extends along a substantially transverse axis A 48 .
  • the distal end of the braking portion 41 of each arm 4 a and 4 b form the distal end 49 of the braking arm 4 a or 4 b .
  • the axes A 34 a , A 34 b and A 48 are substantially parallel.
  • the drive device 9 includes a support plate 91 , the drive portions 45 of the braking arms 4 a and 4 b and a torsion spring 93 .
  • the support plate 91 cooperates with the proximal ends 48 of the arms 4 a and 4 b .
  • the torsion spring 93 maintains the arms 4 a and 4 b in the braking position by default, with the arms 4 a and 4 b inclined in relation to the ski 10 and overlapping below the sole 12 to brake the ski 10 , for example in the case of a fall when the skis are released.
  • the arms 4 a and 4 b are rotationally movable in relation to the blades 3 a and 3 b about the axes A 34 a or A 34 b , respectively.
  • the drive device 9 incorporates a mechanism which, in the gliding position, makes it possible to bring the distal ends 49 of the braking portions 41 of the arms 4 a and 4 b above the ski 10 , in the direction of the plane P.
  • the arms 4 a and 4 b are movable in transverse translation in relation to the blades 3 a and 3 b , along the direction of axis A 34 a or A 34 b.
  • this mechanism is comprised of ramps, not shown in the drawings, which are provided on the underside of the support plate 91 .
  • the ramps guide the drive portions 45 of the arms 4 a and 4 b , so that the arms 4 a and 4 b come transversely closer to one another when the braking device 1 switches from the braking position to the gliding position.
  • the spring 93 is structured and arranged to push the arms 4 a and 4 b against a stop formed by the blades 3 a , 3 b .
  • the spring 93 is centered around the proximal ends 48 of the arms 4 a and 4 b .
  • the spring 93 is arranged so as to exert a lateral force on the arms 4 a and 4 b in order to space them apart. Consequently, each arm 4 a , 4 b tends to move laterally outward of the ski 10 until its angled drive portion 45 is in contact with a portion of the corresponding blade 3 a and 3 b .
  • This stop is located in the area of the housing 340 a , 340 b .
  • the blades 3 a and 3 b should also be immobilized.
  • the spring 93 is replaced by any suitable elastic mechanism for spacing the arms 4 a and 4 b apart.
  • an assembly element 7 makes it possible to rotationally immobilize the blades 3 a and 3 b in relation to the support 2 , in order to adjust the spacing between the braking portions 41 of the arms 4 a and 4 b , that is to say, the transverse spacing of the arms 4 a and 4 b necessary to pass on either side of the longitudinal edges 13 of the ski.
  • This spacing can be expressed through various transverse distances D between specific portions of each arm, which are measured perpendicular to the plane P.
  • the specific portion can be the proximal end 48 of a braking arm, the distal end 49 of a braking arm, the proximal end 411 of a braking portion 41 of an arm, or the point of the braking portion 41 of an arm that is the closest to the plane P when the arm is in the braking position. It should be noted that it is more appropriate to measure this spacing, that is to say, the transverse distance, in the area of the braking portions 41 .
  • the transverse distance D is measured perpendicular to the plane P, in the area of the proximal end 411 of the braking portions 41 of the arms 4 a and 4 b , that is to say, in the vicinity of the elbow connecting the braking portions 41 to the connecting portion 44 .
  • the braking portions 41 of the arms 4 a and 4 b are not rectilinear but move apart from the plane P between the proximal end and the distal end 49 of the braking portions 41 . Therefore, the proper functioning of the braking device 1 , with respect to the passage of the arms 4 a and 4 b above the ski 10 between the braking position and the gliding position, is dependent upon the dimensioning of the transverse distance D.
  • the blades 3 a and 3 b are flat and coplanar; in other words, they do not overlap one another but extend in the same plane parallel to the upper surface 11 and to the sole 12 of the ski 10 . This reduces the vertical space requirement of the device 1 .
  • a first end 38 a or 38 b of each blade 3 a and 3 b comprises a hinge hole 380 a or 380 b cooperating with a pin 20 a or 20 b projecting from the plate 2 and extending upward along a vertical direction, i.e., along a direction perpendicular to the upper surface 11 of the ski when the plate is fixed on the ski.
  • the hinge hole 380 a or 380 b and the pin 20 a or 20 b jointly form the rotational articulation of the corresponding blade 3 a or 3 b with the plate 2 about the axes Z 3 a and Z 3 b , respectively.
  • the axes of rotation Z 3 a and Z 3 b are located on both sides of the plane P and therefore are distinct, i.e., non-aligned.
  • the axes Z 3 a and Z 3 b are perpendicular to the upper surface 11 of the ski 10 , to the sole 12 of the ski 10 , and to the plate 2 .
  • the axes Z 3 a and Z 3 b are parallel and separated by a non-zero distance. Alternatively, they can be inclined in relation to a direction perpendicular to the upper surface 11 of the ski 10 , to the sole 12 of the ski 10 , and to the plate 2 .
  • the pins 20 a and 20 b translationally immobilize the blades 3 a and 3 b in relation to the support 2 , because they make a pivot connection by cooperating with the hinge holes 380 a and 380 b of the blades 3 a and 3 b .
  • the assembly of the pin 20 a or 20 b in the associated hinge hole 380 a or 380 b can be carried out using conventional clip-on fasteners.

  • the blades 3 a and 3 b behave like two gears that are rotationally movable along the axes Z 3 a and Z 3 b , the tooth 35 constantly meshing with the notch 36 .
  • the tooth 35 abuts against the bottom of the notch 36 .
  • at least one of the lateral walls of the tooth 35 is in contact with the walls of the notch 36 .
  • the tooth 35 cooperates with the notch 36 so that a rotation of one of the blades 3 a or 3 b , in a first direction and about its axis of rotation Z 3 a or Z 3 b , causes the rotation of the other blade 3 b or 3 a in the opposite direction, about its axis of rotation Z 3 a or Z 3 b .
  • This specific feature enables a fast and balanced adjustment of the spacing of the blades 3 a and 3 b , and therefore of the braking arms 4 a and 4 b . Indeed, the angular displacement of one blade 3 a or 3 b is thus automatically reflected on the other blade 3 b or 3 a , symmetrically in relation to the plane P.
