Definitions

  • the invention relates to a ski brake according to the preamble of claim 1.
  • a ski brake of this type is described, for example, in AT-PS 37 ⁇ .11 ⁇ . Even if in this document the braking device itself consists of a one-piece, multi-curved single spring wire bracket, the possibility of manufacturing the braking device from a two-piece bracket, the individual bracket parts of which are also bent several times, is also disclosed.
  • an indentation running in the longitudinal direction of the braking device and approximately V-shaped in cross section is provided on the actuating pedal, the height of which approximately corresponds to the wire diameter.
  • the retraction of the two wire brake arms within the ski outline is achieved in the last phase of depressing the actuation pedal, but the extent of this pivoting is limited by the wire dimensions due to the design. This limits the use of the known ski brake to an arrangement directly on a ski.
  • the aim of the invention is to further develop a ski brake of the type mentioned at the outset in such a way that the braking device has an increased swiveling capacity and can therefore be used effectively in conjunction with a swivel plate or a touring plate.
  • the connecting spring is formed by a plastic spring
  • the supporting web of the plastic spring can be dimensioned independently of those areas of this spring which are articulated on the mutually facing sections of the two wire brake arms.
  • An embodiment according to the features of claim 8 enables a particularly simple and expedient design of the holder of the connecting spring.
  • the desired brake position of the ski brake can also be determined independently of the length of the plastic spring, whereby plastic springs of the same dimensions can be produced for different types of ski brakes, for example for adults and children.
  • FIGS. 1 and 2 in mutually associated cracks, show a first exemplary embodiment of a ski brake according to the invention in the braking position, FIG. 1 being a longitudinal section along the line II in FIGS. 2 and 2, a plan view of FIG. 1 3 and 4 cracks similar to Fig.l and 2 with the difference that the connecting spring is biased and the two wire brake arms are spread apart and the Fig.5 and 6 cracks also similar to Fig. 1 and 2 in the Braking device ready.
  • 7 and 8 show, in mutually associated cracks, a second exemplary embodiment of the ski brake according to the invention in the braking position, FIG. 7 being a longitudinal section along line VII-VII of FIG 8 and 8 is a plan view of FIG. 7 and FIGS. 9 and 10 also show cracks similar to FIGS. 7 and 8 in the standby position of the braking device.
  • 1 to 6 show a ski brake designated in its entirety with 1, the base plate 2 of which is formed, for example, in one piece with a pivotable soleplate or a touring plate or is mounted on a ski in any known manner and at one end bearing points 2a for a pivot axis 6 are provided.
  • additional bearing points 2b are arranged on the base plate 2, in which sections of wire brake arms 5 to be described later are mounted.
  • the bearing points 2b for the wire brake arms 5 are expanded upwards and open. They are, for example, U-shaped rails which are symmetrical with respect to the longitudinal axis of the ski brake and have oblong holes 3a (seen from the front or from the rear). 3 completed which rails 3 in .
  • the base plate 2 has an approximately rectangular relief 2c for an actuation pedal 4 articulated on the pivot axis 6.
  • a guide track 2e running in its longitudinal direction and a groove 2f likewise running in its longitudinal direction.
  • the actuating pedal 4 is approximately rectangular and has an approximately square opening 4b in its upper surface designed as a step surface 4a symmetrical to its longitudinal axis and at a short distance from the pivot axis 6.
  • Side walls 4c and a front wall 4d of the operating pedal 4 are bent toward the top of the ski.
  • the side walls 4c are provided with elongated rounded recesses 4e for the wire brake arms 5.
  • the side walls 4c In the pedal section remote from the pivot axis 6, the side walls 4c have cranked tabs 4f in the direction of the longitudinal axis of the ski brake 1.
  • the Opening 4b in the actuating pedal 4 is equipped with boundary walls, the front being 4h, the side 4i and the rear 4j.
  • the front boundary wall 4h has an exemption 4k.
  • the front section of the actuation pedal 4 forms a guide 4g for the sections of the wire brake arms 5, which is delimited by the tread plate 4a, the side walls 4c, the front wall 4d, the tabs 4f and the front boundary wall 4h of the opening 4b.
  • the wire brake arms 5 consist of a multiply bent spring wire and, as can be seen particularly from FIGS. 2, 4 and 6, are designed symmetrically. As can be seen in FIG. 6, sections 5a of the wire brake arms 5 are arranged approximately parallel to the longitudinal axis of the ski brake 1 in the plan view. These sections 5a can, for example, be provided with plastic injection (not shown here) and are referred to below as brake mandrels. Sections 5b of the wire brake arms 5 adjoin the brake mandrels 5a at an acute angle to the longitudinal axis of the ski brake 1. Further cross sections 5c, each acting as a pivot axis of the individual wire brake arms 5, are connected to it.
  • the cross sections 5c of the wire brake arms 5 are pivotally mounted in the bearing points 2b of the base plate 2. This is followed by further wire sections 5d, which extend parallel to the longitudinal axis of the ski brake 1 and extend within the actuation pedal 4 and are held by the tabs 4e. Further brake arm sections 5e each run at an obtuse angle to the longitudinal axis of the ski brake 1. They carry a connecting spring 7, which is equipped with legs 7a, the end regions of which form a loop 7b. A part of the loop 7b designed as a crosspiece 7c runs in the guideway 2e of the base plate 2.
  • Leg springs serving as set-up spring 8 are arranged around the pivot axis 6, their side walls 4c of the actuating pedal 4 adjacent legs 8a act on the actuating pedal 4 in the direction of the active braking position of the ski brake 1, while the legs 8b of the positioning springs 8 which are adjacent to the longitudinal axis of the ski brake 1 hold down the transverse web 7c, at least one hook section 8c of the legs 8b engaging over the transverse web 7c.
  • the connecting spring 7 lies at least partially on the front boundary wall 4h of the opening 4b, the actuating pedal 4 being simultaneously pressed up by the leg spring 8.
  • the connecting spring 7 is slightly bent and the brake mandrels 5a extend at a short distance from the side surfaces of the ski brake 1 or the ski (not shown here) (see FIG. 2).
  • the brake mandrels 5 simultaneously perform an outward movement and then back again during the pivoting movement from the ready position into the brake division inside towards the ski. Damage to the side surfaces of the ski (not shown here) is avoided on the one hand, and on the other hand, when using the ski brake according to the invention with a plate binding, an obstacle to the braking process by the pivotable sole plate is excluded.
  • FIG. 7 to 10 show a ski brake designated in its entirety by 10, the base plate 20 of which, for example, is formed in one piece with a pivotable soleplate or a touring plate or is mounted on a ski in any known manner and at one end of bearing positions 20a for a pivot axis 60 are provided. At a distance from the pivot axis 60, additional bearing points 20b are arranged on the base plate 20, in which sections of wire brake arms 50 to be described later are mounted. The bearing points 20b for the wire brake arms 50 are expanded at the top and are open.
  • the base plate 20 has an approximately rectangular exemption 20c for an actuation pedal 40 which is angled on the pivot axis 60, the exemption 20c being delimited by a base 20d.
  • the actuation pedal 40 is approximately rectangular and has an opening 40b in its upper surface designed as a step surface 40a symmetrical to its longitudinal axis and at a short distance from the pivot axis 60.
  • Side walls 40c and a front wall 40d of the actuation pedal 40 are bent in the direction of the ski surface.
  • the side walls 40c are provided with elongated rounded recesses 40e for the wire brake arms 50.
  • the side walls 40c In the pedal section remote from the pivot axis 60, the side walls 40c have tabs 40f bent in the direction of the longitudinal axis.
  • the opening 40b in Actuator pedal 40 is equipped with boundary walls, the front with 40h, the side with 40i and the rear with 40j. Through the opening 40b, snow that may accumulate can be pressed out.
  • the front section of the actuation pedal 40 forms a guide 40g, which is defined by the tread plate 40a, the side walls 40c, the front wall 40d, the tabs 40f and the front boundary walls 40h of the opening 40b, for sections of the wire brake arms 50 which will be described in more detail later.
  • the wire brake arms 50 consist of a multi-curved spring wire and, as can be seen particularly from FIGS. 8 and 10, are designed symmetrically. As can be seen in FIG. 10, sections 50a of the wire brake arms 50 are arranged approximately parallel to the longitudinal axis of the ski brake 10 in plan view. These sections 50a can, for example, be provided with a plastic injection, not shown here, and are referred to below as brake mandrels. Sections 50b of the wire brake arms 50 adjoin the brake mandrels 50a at an acute angle _ ⁇ ur the longitudinal axis of the ski brake. Further, each acting as a pivot axis of the individual wire brake arms 50, cross sections 50c are connected to it.
  • the cross sections 50c of the wire brake arms 50 are pivotally mounted in the bearing points 20b of the base plate 20. This is followed by further wire sections 50d, which extend parallel to the longitudinal axis of the ski brake 10 and extend within the actuation pedal 40 and are held by the tabs 40e.

Abstract

Frein de ski constitué d'un étrier métallique en deux parties, dans lequel les parties individuelles de l'étrier sont pliées en U ou repliées plusieurs fois, et qui comporte deux bras métalliques de freinage. On peut faire pivoter le frein de ski, à l'encontre de la force d'au moins un ressort de redressement, d'une position de freinage à une position d'attente, dans laquelle les extrémités libres des deux bras métalliques de freinage pivotent en direction de l'axe longitudinal du ski, c'est-à-dire qu'elles rentrent ou pivotent vers l'intérieur au-dessus de la partie supérieure du ski. Le frein de ski est pourvu d'une pédale d'actionnement sur laquelle appuie la chaussure de ski, la face inférieure de ladite pédale formant au moins partiellement un guide pour des sections des deux parties d'étrier; les deux parties se faisant face des bras de freinage portent un ressort de jonction. Ce ressort de jonction (7) possède une pièce centrale transversale (7c) avec laquelle il repose contre ou dans une voie de guidage (2e) de la plaque de base (2). En position de freinage, le ressort de jonction (7c) se trouve partiellement sur la paroi de délimitation frontale (4h) d'une ouverture (4b) ménagée dans la pédale d'actionnement (4). Deux ressorts en spirale sont prévus pour faire office de ressort de redressement (8). Le ressort de jonction (70) peut également être réalisé sous forme d'un ressort en plastique ayant sensiblement une forme en U lorsqu'il est vu de l'avant.
