Definitions
- the present invention relates to a ski brake consisting of an articulated spring metal hoop transversely, by its sides, on a base and presenting, in its middle part, an open loop flattened bearing on the base to form a return spring tending to maintain the brake in active braking position, the middle part of the hoop carrying in addition a tilting pedal around said middle part, this pedal being intended to receive the pressure of the shoe for raise the brake against the action of said loop.
- Patent FR 2 322 627 discloses a brake provided with a pedal that rises horizontally under the effect of a spring horn horn, so as to place this pedal in a position favorable to its actuation by the shoe.
- brakes such as the brake represented in patents EP 0 893 144 and FR 2 741 275 comprising two separate brake arms articulated on a pedal further connected to the brake base by a auxiliary link so as to constitute a parallelogram type joint now the pedal in a substantially horizontal position.
- a auxiliary spring acts on the link to lower the brake in the active position.
- the present invention aims, in a brake consisting of a single arch of spring metal, without auxiliary spring for lowering it in position active, to ensure the recovery of the pedal in a substantially horizontal position without spring auxiliary.
- the brake according to the invention is characterized in that underside of the pedal has a protuberance of widening cross-section of the summit towards his base and engaging in the open loop of the rollbar in the raised position of brake, this protuberance having the effect of spreading elastically said loop when engaged in the loop, the pinching of the loop exerted on the protuberance having the effect, upon the release of the pressure on the pedal, to straighten at least partially pedal.
- Such a brake is very simple. It is consisting of a minimum number of parts, namely a metal bow, a base and a pedal, the base and the pedal being preferably made of injected plastic.
- the ends of the arch metal are preferably coated with plastic reducing aggression, as it is the case of all current brakes.
- the attached drawing represents, as an example, a implementation of the brake according to the invention.
- Figure 1 shows a side view
- Figure 2 is a back view, that is to say seen from the back of the ski towards the front.
- FIG. 3 represents the brake seen from below, in position raised under the pressure of a shoe but without the ski.
- the brake represented consists of three pieces, know a base 1 of plastic, a hoop 2 spring-loaded metal, for example steel, and a pedal 3 made of plastic, parts to which he must be added plastic coatings 4 and 5 of ends of the arms 21 of the arch 2.
- the base 1 is fixed by means of screws on a ski 6.
- the bow 2 has, on each side, a double elbow at the base 1, these doubles elbows defining two aligned horizontal sections between them 22 forming the axis of articulation of the brake in the base 1 which has for this purpose two notches 7 ( Figures 1 and 3) forming bearings for sections 22 of the hoop 2.
- the hoop 2 has two oblique symmetrical sections diverging 23 serving, in known manner, to bringing the arms 21 closer when the brake is raised by the support of these sections 23 on the base 1.
- the hoop 2 presents again two horizontal rectilinear sections aligned with one another 24 serving as an axis of articulation to the pedal 3.
- the middle part of the arch 2 forms a loop open downward and leaning on a flat face of the base 1 on which it can slipping.
- the plan of the open loop 25 is inclined relative to the vertical in the same direction as the plane of the sections 23, but with a steeper slope, forming an angle with the plane of the sections 23.
- the open loop 25 holds the hoop 2 in the base 1.
- the pedal 3 is retained on the hoop 2 by two tabs 31 passing over the straight sections 24 of the hoop 2 and fixed notch on two nipples 32 of the pedal.
- the pedal 3 On its underside, that is to say the same side that the tabs 31, the pedal 3 has a constituted protuberance, in the example shown, of a longitudinal median rib 33 extending according to the axis of symmetry of the pedal and having a trapezoidal section as can be seen in the figure 2.
- Figures 1 and 2 show the brake in position lowered active, that is to say in the absence of shoe.
- this pressure tends to turn the brake roll in the direction of the arrow F1, figure 1, that is to say to raise the brake in inoperative position.
- the plan containing the open loop 25 gets closer to the plane containing sections 23 because of the bracing and sliding of the buckle 25 on the base.
- This displacement is accompanied by a deformation of the arch 2 torsion at the level of sections 24, which effect of strongly arming the spring constituted by this arch.
- the pedal 3 comes to fall back substantially in the plane of sections 23, i.e. in the plane of the arch as shown in the figure 3.
- the brake roll When releasing the fixation, voluntary or case of fall, the brake roll resumes the position shown in Figures 1 and 2 under the pressure of the open loop 25.
- the loop 25 being further solicited to the spacing by the protuberance 33, she strongly clip this protuberance. This pinch acting on the ramps 34, it generates a component which tends to push the protrusion 33 out of the loop 25, so that the pedal 3 is rectify the position represented in Figures 1 and 2. If the plastic constituting the pedal 3 has a significant coefficient of friction, the pedal does not recover instantly, this recovery can take one or two seconds, this which is not a disadvantage. More plastic is hard plus the recovery is fast.
- the protuberance 33 could have a different shape, for example a spherical cap shape or a shape conical or frustoconical, or any other form capable to discard the loop 25 by generating a reaction expulsion, that is to say a cross-section widening from its summit towards its base.
- the protuberance could be formed by a insert, made of a material different from the material of the pedal.
- the protuberance could be covered of a material with a low coefficient of friction and sufficient hardness, for example in the form of a cap.

- Frein pour ski constitué d'un arceau en métal ressort (2) articulé autour d'un axe transversal, par ses côtés, sur une embase (1) et présentant, en sa partie médiane, une boucle ouverte aplatie (25) prenant appui sur l'embase pour constituer un ressort de rappel tendant à maintenir le frein en position abaissée active, la partie médiane de l'arceau portant en outre une pédale (3) montée basculante autour de ladite partie médiane, cette pédale étant destinée à recevoir la pression de la chaussure pour relever le frein contre l'action de ladite boucle ouverte, caractérisé en ce que la face inférieure de la pédale présente une protubérance (33) de section transversale allant en s'élargissant de son sommet en direction de sa base et s'engageant dans la boucle ouverte (25) de l'arceau en position relevée du frein, cette protubérance ayant pour effet d'écarter élastiquement ladite boucle ouverte (25) lorsqu'elle est engagée dans la boucle, le pincement de la boucle exercé sur la protubérance ayant pour effet, lors du relâchement de la pression sur la pédale, de redresser au moins partiellement la pédale.
- Frein de ski selon la revendication 1, caractérisé en ce que ladite protubérance (33) est en forme de nervure longitudinale de section trapézoïdale ou en V.
