Definitions

  • the invention relates to a ski brake according to the preamble of claim 1.
  • Such a ski brake is described in DE-OS 31 36 079.
  • a displacement body is arranged in the base plate, which causes the connecting spring to bend when the actuation pedal is depressed and thus causes the free ends of the two wire brake mandrels to pivot in against the vertical longitudinal center plane of the ski brake.
  • This ski brake has the disadvantage that the force required for swiveling engages in the middle of the spring connecting the two wire brake mandrels, which is therefore subjected to great stress, especially since the angled ends of the wire brake mandrels inserted in the spring are at a distance from the center of the spring be found.
  • EP-AI 45 698 describes a ski brake in which the connecting spring between the angled and mutually directed end sections of the wire brake mandrels is designed as a leaf spring which is firmly connected to an actuating pedal.
  • this configuration has the result that the leaf spring is not only subjected to bending but also to torsion when the ski brake is depressed and swung up.
  • the two wire brake arms are brought up by a pull rod, which is articulated at one end on the pedal and at the other end with is provided with a piston.
  • This piston is guided in a cylindrical housing and acted on by a compression spring.
  • the leaf spring which is deflected in the braking position, is pivoted through an angle, which results in the leaf spring bending back and the inward rotary movement of the ends of the wire brake arms carrying the brake blades.
  • the invention has for its object to eliminate the disadvantages of the known designs and to provide a ski brake in which the contact surfaces of the swiveling force of the wire brake arms are in the region of the angled ends of the wire brake arms, so that the connecting spring has less bending stress due to direct force application is exposed. Furthermore, the designer should be given a greater opportunity with regard to the choice of materials.
  • the measure of claim 3 ensures that the free ends of the wire brake arms are pivoted into the ready position with reduced friction.
  • the subject of claim 4 ensures constant guidance of the intermediate member on the base plate.
  • the support surface and guide surfaces can be arranged separately from one another, as a result of which the designer can more easily carry out those structural measures which are necessary for pulling the free ends of the wire brake arms into the ready position.
  • the power flow from the base plate into the wire brake arms is improved.
  • the subject of claim 5 limits the range of motion of the free end of the extension, which is determined on one side by the guide surface, on the other side.
  • the measure of claim 6 enables reliable anchoring of the ends of the two leg springs in the extension of the intermediate member. '' Furthermore, the two leg springs can be dimensioned longer because their ends are next to each other.
  • the design of the extension according to the features of claim 9 enables the designer to determine the timing of the retracting movement of the two brake arms.
  • Claim 10 includes a measure by which an advantageous embodiment of the intermediate member in connection with separate support surfaces and guide surfaces is brought about.
  • the embodiment according to claim 11 is characterized in that the extension of the intermediate member is guided under positive locking.
  • the ends of the leg springs can be supported directly on the base plate and thus be independent of the extension. This also makes it possible to use a single spring, which is also easy to assemble.
  • claim 13 is characterized by a particularly simple structure, the designer having a greater scope for determining the distance between the guide surface and the support surface.
  • FIG.l is a section along the line II in Fig. 2 through a first embodiment in the braking position and in Fig.2 an associated plan view. 3 and 4, the ski brake during the depression of the actuation pedal is shown in section along the line III-III in FIG. 4 and in a top view. 5 is a section through the ski brake in the standby position along the line VV in FIG. 6 and FIG. 6 is an associated plan view. 7 shows a front view of the intermediate member of a second embodiment and FIG. 8 shows an associated side view.
  • FIGS. 9 is a section along the line IX-IX in FIG.
  • FIG. 10 through the ski brake in the braking position and FIG. 10 is an associated top view.
  • Fig.l 1 shows a section through this ski brake during the depression of the operating pedal along the line XI-XI in Fig.12 and Fig.12 an associated plan view.
  • Fig.13 illustrates a section according to the Line XIII-XIII through the ski brake in the ready position and Fig. 14 an associated top view.
  • FIGS. 15-17 show a fourth embodiment of the ski brake. 15 is a section through the ski brake in the braking position, FIG. 16 is an associated top view.
  • Figures 17 and 18 show this ski brake in the ready position, similar to Figures 5 and 6.
  • Figure 19 shows a top view of the base plate and Figure 20 shows a top view of the intermediate member. For the sake of simplicity, the top views of the skis were not shown.
  • the ski brake shown in FIGS. 1-6 is designated 1 in its entirety. It has a base plate 2 with a base 2a which is attached to a ski 10 e.g. is attached by means of screws 3. At the base 2a are upwardly projecting strip-shaped side parts 2b which run in the longitudinal direction of the ski brake 1. A transverse axis 4 is fastened in the bores of the two side parts 2b, on which on the one hand an actuating pedal 5 and on the other hand two set-up springs designed as leg springs 6 are mounted.
  • the operating pedal 5 has a stop 5a and two bent tabs 5b.
  • funnel-shaped transverse bores 2c are recessed in the two side parts 2b of the base plate 2, in which two wire brake arms 7 are pivotally mounted with their transverse sections 7b.
  • Each wire brake arm 7 has a section located outside of the base plate 2, which may have a plastic encapsulation serving as a brake blade (not shown in the drawing) and is referred to below as the brake mandrel 7a, the section 7b already mentioned, a section 7c adjoining this, which runs approximately parallel to section 7a, and an end section 7d connected to section 7c at an obtuse angle.
  • the end sections 7d of the two wire brake arms 7 are directed towards one another and connected to one another by a connecting spring 8.
  • the end sections 7d of the wire brake arms 7 are mounted in the actuating pedal 5 in a known and therefore not described manner.
  • An intermediate member 9 is placed on the connecting spring 8, which is designed as a helical spring, and has a cylindrical sleeve 9a with an extension 9b adjoining it.
  • the extension 9b extends approximately radially to the cylindrical sleeve 9a.
  • This extension 9b is designed like a frame, angled ends 6a of the two leg springs 6 being suspended in the frame, the other ends of which are supported on the underside of the actuation pedal 5.
  • the sleeve 9a of the intermediate member 9 has a hole that is elongated towards the two sides of the ski brake 1 (see FIG. 7). This favors a swiveling apart of the end sections 7d of the two wire brake arms 7 with reduced friction and prevents them from jamming.
  • the extension 9b of the intermediate member 9 is at a distance from the top of the ski 10.
  • the intermediate member 9 is held in one position by the angled ends 6a of the two leg springs 6, in which the sleeve 9a abuts the stop 5a of the actuating pedal 5.
  • the intermediate member 9 is supported in the end position (ie in the ready position of the ski brake 1) with its extension 9b against the force of the connecting spring 8 as a Support area 2f acting area of the guide surface 2e.
  • the end sections 7d of the two wire brake arms 7 are furthest away from the transverse axis 4, and the two sections 7a are pivoted in against the vertical longitudinal center plane of the ski brake 1.
  • the displacement of the end sections 7d in the longitudinal direction of the actuation pedal 5 is brought about essentially according to the toggle lever principle.
  • the free ends of the two brake mandrels 7a of the wire brake arms 7 have a distance a ⁇ .
  • this distance increases to a2, as a result of which the free ends of the brake mandrels 7a are at a greater distance from the two side surfaces of the ski 10. This enables the two brake mandrels 7a of the wire brake arms 7 to pass the two side surfaces of the ski more easily and without the risk of getting caught.
  • FIG. 7 and 8 show a variant for the configuration of the intermediate member 9 ', the extension 9'b of which is T-shaped in plan view.
  • the transverse section 9'c of the extension 9'b there are recesses 9'd which serve to receive the hook-shaped bent ends of the two leg springs which are intended to be used to set up the actuation pedal.
  • FIGS. 9-14 The embodiment of a ski brake 1 "shown in FIGS. 9-14 is similar to that described first. It also has a base plate 2" a base 2 "a, which is fastened to a ski 10" by means of screws 3 ".

Abstract

Un frein (1) pour skis comprend deux branches de freinage (7) en fil métallique montées de façon pivotable sur une plaque de base (2) et dont les sections terminales (7d) sont mutuellement reliées par un ressort (8). Le frein (1) est maintenu en position de fonctionnement par une pédale d'actionnement (5) agencée du côté supérieur du ski et que l'on enfonce contre la force d'au moins un ressort de levage (6). Les extrémités libres (7a) des branches de freinage (7) en fil métallique pivotent dans le sens de l'axe longitudinal du ski (10). Afin d'améliorer la transmission de forces de la plaque de base (2) aux branches de freinage (7) en fil métallique lorsque l'on enfonce la pédale d'actionnement (5), un organe intermédiaire formé d'un manchon cylindrique (9a) relié à une saillie (9b) est monté de manière articulée sur les sections terminales (7d). Dans la position de fonctionnement, la saillie (9b) s'appuie sur une surface d'appui (2f) de la plaque de base (2).
