Definitions

  • the invention relates to a ski brake according to the preamble of claim 1.
  • the known ski brakes of this type had the disadvantage that the brake blades sometimes damaged the upper ski edges during the pulling-in process and got stuck on the upper ski edges when the skier fell, i.e. when the brake blades were to be released, which was particularly the case with icing.
  • the object of the invention is therefore to eliminate these disadvantages and to create a ski brake which prevents damage to the upper ski edges and also prevents the two brake blades from getting caught.
  • the already existing clamping claws which serve to fix the guide rail are also to be used for guiding the brake blades, for which they have not previously been used.
  • a U-shaped wire bracket serving as a pedal which is under the influence of a positioning spring and whose leg ends are mounted in a housing, can be pivoted together with this housing on a ski-fixed transverse axis by a certain angle.
  • brake blades are mounted on axes which are formed by the two legs of the bracket and which run in the longitudinal direction of the ski when the ski brake is in the ready position, and pivotable by 90 °.
  • the two brake vanes are - seen in the direction of their axes - angular and are in the ready position with their one end area on one of the prismatic sliding blocks, each with an inclined surface, and with their other end area on one of the support blocks assigned to them, which are also on the Ski top are attached.
  • the bracket serving as a pedal is first pivoted up from its ready position, the individual brake blades sliding outward over the contour line of the ski on the inclined surfaces of the slide blocks assigned to them.
  • the two brake plates are pivoted through 90 °, so that the plate plane is perpendicular to the longitudinal direction of the ski.
  • This ski brake is not only complicated in its structure, but also difficult to assemble, since a total of four blocks have to be fastened separately on the top of the ski.
  • the clamping claws which are already present and are intended for fastening the guide rail for a ski binding part, in particular for the heel holder, are designed such that they guide the brake vanes. The clamps are therefore used for two different purposes at the same time.
  • wedge pieces are attached to the upper side of the ski, the upper boundary surfaces of which serve as guide surfaces for the two cranked brake mandrels, but these guide surfaces serve only the purpose, when the pedal is depressed, to move the brake mandrels in the longitudinal direction of the ski entails lifting the central sections of the brake mandrels.
  • a recess delimited by a control curve is provided in the edge of the shell-shaped pedal.
  • the ski brake according to DE-AS 2605506 does have lateral guide surfaces for the two brake blades, but these surfaces are arranged on a holder by which the support plane for the ski shoe is raised in an undesirable manner. Similar explanations are shown in US Pat. No. 4,687,221 and PCT-WO 80/01759.
  • the measure of claim 3 increases the stability and at the same time simplifies assembly, especially since the holder thus formed can be resiliently placed as a unit on the guide rail.
  • each clamping claw design the guide surface of each clamping claw as a curved surface, e.g. as a conical or cylindrical surface.
  • the embodiment according to claim 4 has proven to be particularly advantageous for reasons of manufacture.
  • the subject of claim 5 makes pivoting and retracting the brake blades easier.
  • the measure of claim 6 has the advantage that an accumulation of snow on the two clamps is prevented.
  • the feature of claim 7 ensures a reliable position of the brake blades in the ready position of the braking device.
  • FIG. 1 shows a side view of the ski brake in the braking position and FIG. 2 shows an associated top view.
  • FIG. 3 illustrates a side view of the ski brake which is in the ready position and
  • FIG. 4 shows an associated top view.
  • FIG. 5 is a section along the line VV in FIG. 4.
  • FIG. 6 shows a section similar to FIG. 5, but in a position in which the two brake mandrels with the brake blades are in the process of being pivoted in or out or after the ski brake is ready.
  • 1 denotes a ski, on the top 1a of which a guide rail 2 is fastened.
  • This guide rail 2 carries at its front end a ski brake 3 to be described in more detail, which is fastened to the ski 1 by means of screws 4 which pass through holes in embossments 2c of the base 2a of the guide rail 2.
  • the ski brake so as to be adjustable relative to the guide rail 2.
  • the guide rail 2 is not itself screwed, but is held here by two clamping claws 5, which are fastened to the ski 1 by screws 4, which also penetrate lateral recesses 2d of the guide rail 2. This construction facilitates a deflection of the ski 1 when driving through hollows.
  • the two clamping claws 5 are made of plastic and are formed in one piece with a web 5a connecting them with a thickness of 0.5-1 mm.
  • Each claw 5 has one in the longitudinal direction of the ski extending, from the ski brake 3, rear area 5b, which is penetrated by the screws 4 and forms the actual holder of the guide rail 2. This is adjoined by an area adjacent to the ski brake 3, which is designed as an extension 5c and which carries a flat guide surface 5d. This includes with the upper side 1a of the ski 1 - seen in cross section according to FIG. 5 - an angle ⁇ between 20 ° and 65 °, preferably an angle of 45 °.
  • the guide surface 5d is slightly inclined in the direction of the ski brake 3, so that the edge 5f formed by the guide surface 5d and the outer boundary surface 5e forms an acute angle ⁇ of up to 10 °, preferably 5 °, with respect to the upper side 1a of the ski 1 .
  • the bearing surface 5i which adjoins the guide surface 5d, is inclined at an angle ⁇ with respect to the upper side 1a of the ski 1, the size of which lies in the range of the angle ⁇ , in the present case corresponds to that of the angle ⁇ .
  • the end face 5g of each clamping claw 5 is also inclined with respect to the upper side 1a of the ski 1, specifically at an angle ⁇ between 45 ° and 75 °, preferably at an angle of 60 °. 5h denotes the edge between the end face 5g and the guide surface 5d.
  • the ski brake 3 itself is of a known type. It has a base plate 3a, in the edges of which two multi-angled brake mandrels 3b made of steel wire are pivotally mounted, the upper ends of which are directed towards the vertical longitudinal center plane and are accommodated in a pedal 3c. The free ends of the brake mandrels 3b carry brake blades 3d.
  • the pedal 3c is pivotally mounted at one end in the base plate 3a.
  • heel holder On the guide rail 2 a known, not shown, heel holder is slidably guided.
  • This has a latching device, the latching member of which can optionally engage in one of the recesses 2b in the base 2a of the guide rail 2.
  • This allows the heel holder to be fixed in different positions.
  • a ski boot is indicated, with which the pedal 3c is depressed when entering the heel holder.
  • the invention is not tied to the exemplary embodiment shown in the drawing and described in the foregoing. Rather, various modifications thereof are possible without leaving the scope of the invention.
  • the two clamping claws do not have to be connected to one another by a web, but rather can separately attached to the ski.
  • the extensions of the clamping claws can also overlap the guide rail from above.
