Definitions

  • the present invention relates to ski brakes comprising two braking arms, arranged on either side of the ski, and which are subjected to the action of a spring tending to return them to their active position.
  • each braking arm may advantageously consist of a metal wire suitably bent to form a lower section carrying a brake shoe, an intermediate section pivotally mounted on the ski and an upper section subjected to the shoe pressure when it is in place.
  • the upper end of the two braking arms thus formed protects a control pedal, or a similar member, on which the boot comes to rest When it is put in place on the ski.
  • a control pedal or a similar member, on which the boot comes to rest
  • the shoe automatically causes the brake arms to pivot into their retracted rest position; but, under the effect of the return spring, these are deployed immediately as soon as the shoe escapes.
  • Some of these ski brakes include means ensuring the retraction of the brake pads in the retracted position, so that they do not overflow on the sides of the ski.
  • the retraction of the braking arm in the retracted position is obtained by pressing a plate fin or - mable or articulated quadrilateral disposed under the location of the shoe so as to be flattened by it during its installation.
  • the arrangement is such that the flattening of this plate or of this articulated quadrilateral then brings the two braking arms closer together, after they have been raised to the retractable position.
  • control plate is a curved blade
  • this exerts a high pressure under the shoe.
  • this is likely to disrupt the conditions for releasing the boot when the retaining binding is released on the ski.
  • control plate consists of an articulated quadrilateral, the system provided is particularly complicated and expensive. In addition, it is unreliable especially since its operation is sensitive to frost.
  • the retraction of a braking arm can be obtained by pivoting the latter in a bearing whose axis, located in a transverse plane, sal to the ski, is inclined relative to the upper face of this one (figure 11 of French patent 73 17074 : publication 2.228.506).
  • the advantage of such a system is that it is extremely simple.
  • it has the disadvantage that the slightest deformation of the braking arm can cause it to rub and possibly block on the edge of the ski, since the retraction of the arm is carried out at the same time as its lifting.
  • Another disadvantage lies in the fact that to obtain a sufficient retraction important, it is necessary that the articulation bearing is located relatively high, which is unacceptable if the brake is placed under the shoe.
  • This ski brake is essentially characterized in that the upper section of each of its braking arms carries a pivoting control flap connected to the flap of the upper section of the other arm by an upper hoop and in that each of these flaps has two separate bores serving as articulation bearings respectively for the upper section of the corresponding arm and for the respective branch of the upper connecting arch, these bores forming an angle between them such that the pivoting of the two flaps around the branches of the upper arch reason, under the effect of the pressure of the shoe, determines a bringing together of the lower sections of the braking arms.
  • This ski brake comprises two braking arms 1 arranged symmetrically with respect to the median longitudinal plane of the ski S. Each of these arms is bent in a plane so as to have a lower section 2 carrying a braking pad 3, an intermediate section 4 pivotally mounted in a bearing 5, and an upper control section 6.
  • the two bearings 5 are carried by a plate 7 serving as a base for mounting the assembly on the ski S by means of screws 8.
  • These two bearings are arranged so as to somehow materialize a transverse axis XY for pivoting of the two braking arms 1.
  • the intermediate sections 4 of these have a certain clearance inside these bearings.
  • each braking arm carries a pivoting control flap 9 and the two flaps thus provided are connected by an upper arch 10, made of metal wire, as are the braking arms 1.
  • Each of the flaps 9 has two separate bores 11 and 12 serving as articulation bearings, respectively at the end of the upper section of the corresponding arm and at the respective branch of the connecting arch 10.
  • the axes of these bores do not are not in the extension one on the other nor parallel. Indeed, they form an angle between them such that the flat folding of the two flaps 9 against the ski, by pivoting around the branch of the upper link arch 10, determines a bringing together of the braking pads 3 by movement of the intermediate sections 4 of the arms 1 inside the bearings 5.
  • the pivoting arms 1 are returned to their active braking position is provided by a helical tension spring 13, one end of which is attached to the elbow of the upper link arch 10, while its opposite end is attached to a fixed axis 14 carried by the mounting plate 7.
  • a rod 15 Inside this spring is arranged a rod 15 whose / length is such that it serves as a stop limiting the deployment of the pivoting arms in the desired position for braking.
  • the brake pads are arranged on either side of the edges of the. ski as shown in FIGS. 1 and 2.
  • the two control flaps 9 they are then slightly raised towards the outside.
  • the main advantage of the ski brake according to the invention lies in the simplicity and efficiency of the means provided for ensuring the retraction of the brake pads in their retracted position.
  • this retraction requires less effort than in the case where it is obtained by folding down a single control pedal pivoting about a transverse axis.
  • this retraction is obtained by the folding of the two flaps 9 pivoting around two axes extending in a longitudinal direction. This folding down therefore requires less effort and the forces exerted are much better distributed than in the case of pressing on a single pedal.
  • this facilitates the installation of the boot in the binding of the corresponding ski, because the final folding of the two control flaps is easier to achieve.
