Definitions

  • the invention relates to a ski brake, as specified in the preamble of claim 1.
  • Such a ski brake is described in AT-FS 372 007.
  • the base plate is designed in the manner of a flat plate on which the individual elements are arranged.
  • this can cause damage and possibly also give rise to icing.
  • the brake bracket is mounted on the base plate itself, and the bearing for the pedal can be moved in the longitudinal direction of the ski brake against the force of compression springs.
  • This design has the disadvantage that if the ski brake is dirty, the U-shaped bearing bracket for the pedal, the legs of which are displaced when the pedal is depressed in bores in the base plate against the force of compression springs, damages the walls of the spring housing, as a result of which the ski brake functions is questioned.
  • the invention has for its object to eliminate the disadvantages of the known designs and a. To create a ski brake in which the individual elements are protected both against dirt and against icing.
  • the design of the housing can be any. However, it has proven to be advantageous if, according to the invention, the features of claim 2 are realized in this housing.
  • a further embodiment of the invention is characterized in claim 3.
  • This embodiment has the advantage that when the brake bracket is in the braking position, the pressure exerted on the brake blades by the snow is passed directly into the base plate and does not load the spring or the springs.
  • the measure of claim 4 enables the brake blades to come to rest within the two sides of the ski during the journey and therefore not hinder the journey even when stones or branches protrude from the slope.
  • the measures of claims 5 to 16 also aim in this direction.
  • the measure of claim 5 makes the control of the two brake mandrels particularly easy by the conically widening bearing bore.
  • the funnel-shaped receiving bores for the sections of the brake mandrels forming the swivel axis are known, for example, from AT-FS 366 271, albeit with a one-piece brake bracket.
  • brake bars or brake mandrels are made from a wire material.
  • the wire material consists of spring steel, which allows an elastic deformation within certain limits.
  • the first solution specified in claim 10 has the advantage that the two brake mandrels are supported within the housing and therefore their guide surfaces are protected against contamination.
  • each brake mandrel could be attached to it by soldering or welding. This type of construction would have the disadvantage, however, that if the stop were damaged or worn, it would be difficult to remove it from the brake mandrel. In the construction specified in claim 11, however, the stop, if it should be worn, can be easily removed at any time and replaced by a new stop.
  • the measure of claim 12 has the advantage that the sleeve bears under prestress on the brake mandrel, and therefore can not wear out as easily as a sleeve that is placed on the brake mandrel with play.
  • the feature of claim 14 improves the abutment of the stop on the longitudinal side wall of the housing, so that point contact is avoided.
  • the second solution specified in claim 15 has the advantage that the stop can be designed in the form of a disk and is therefore easier to manufacture than the sleeve characterized in claim 11.
  • the measure of claim 16 enables the two stops to rest reliably against the outer boundary surface of the longitudinal side walls in any position of the pedal.
  • FIG. 1 is a section along the line I - I in Fig. 2 through a ski brake in the braking position and Fig. 2 is a plan view of the same.
  • a variant in top view is shown in the lower half of FIG. 2.
  • Fig. 3 is a partially sectioned side view of a third and Fig. 4 is an analog view of a fourth embodiment.
  • FIG. 5 shows a fifth embodiment in the braking position in section along the line V - V in FIG. 6 and in FIG. 6 a top view of this embodiment.
  • 7 and 8 show the same embodiment in the driving position in section along the line VII - VII in FIG. 8 or in part along the line VIII - VIII in FIG.
  • FIG. 9 is a Section through a further embodiment of a ski brake according to the line IX-IX in FIGS. 10 and 10 in the braking position, an associated plan view. 11 and 12, analog representations of the ski brake in the driving position are shown, FIG. 11 being a section along the line XI-XI in FIG. 12.
  • FIG. 13 shows a detail of a variant of the ski brake according to FIGS. 9 to 12.
  • a last embodiment is shown in FIG. 14.
  • the ski brake is designated 1 in its entirety. It has a housing 2 serving as a base plate, which is fastened on the upper side of the ski by means of screws, not shown is. Of course, the housing 2 can be held down by a ski binding part, integrated in it, guided on a ski binding part or also glued to the top of the ski.
  • the width of the housing 2 corresponds at least approximately to the width of the ski, which is not shown in the drawing.
  • a pedal 3 is pivotally mounted on an axis 4. At the free end of the pedal 3, a multiply cranked brake bracket 5 is articulated with its central section 5a.
  • Two sections 5c of the brake bracket 5 parallel to the middle section 5a, which are connected to the middle section via two sections 5b and serve as a pivot axis of the brake bracket 5, are mounted in bearing parts 6, which are displaceably mounted in the housing 2 between two guides 2a and 2b and according to Art are formed by sliding blocks.
  • Each bearing part 6 has on the side facing away from the axis 4 an extension 6a, which serves to mount a spring 7 designed as a helical compression spring, the other end of which is accommodated in a recess in the housing 2, which is located between the two guides 2a and 2b.
  • Each section 5c of the brake bracket 5 is followed by a section 5d which runs parallel to the vertical longitudinal center plane of the ski brake 1 and carries a brake paddle 8 at its free end.
  • longitudinal slots 2c are cut out, which are penetrated by the sections 5c of the brake bracket 5.
  • the ski brake is in the braking position 1 in the position shown in FIGS. 1 and 2.
  • the pedal 3 is depressed by the foot of the skier, the two bearing parts 6 move between the guides 2a and 2b against the force of the springs 7 away from the pivot axis 4.
  • the brake bracket 5 in FIG. 1 is pivoted counterclockwise until the toggle lever formed by the pedal 3 and the brake bracket 5 is just above the extended position. In this position, the two brake blades 8 run approximately parallel to the housing 2, but are located outside the outline of the same in a plan view.
  • a variant of the ski brake 1 ' is shown, which differs from the first embodiment only in that a spring 7' designed as a tension spring is provided on each side of the vertical longitudinal center plane of the ski brake, which is articulated on the one hand on section 5c of the brake bracket 5 and on the other hand on a bolt 9 which penetrates the housing 2 in the transverse direction parallel to the underside of the housing.
  • FIG. 3 A similar embodiment of the ski brake 1 "is shown in FIG. 3.
  • a spring 7" acting directly on the pedal 3 is provided, which tries to push the pedal into the position in which it is the brake bracket 5 is in the braking position. If the pedal 3 is depressed by the foot of the skier, the spring 7 "is bent so elastically that the individual sections are in a plane that runs parallel to the depressed pedal 3.
  • FIG. 4 A further embodiment of the ski brake 1 "'is shown in FIG. 4.
  • the pedal 3 is acted upon by a spring 7"' designed as a leg spring, which is wound around the axis 4 of the pedal 3 and of which one leg is at the bottom of the Housing 2 'and the other leg is supported on a shoulder 3a of the pedal 3.
  • the last-discussed embodiment ensures that the pressure exerted by the snow on the brake blade from the side of the axis 4 when the brake blade 8 is in the braking position is passed directly into the housing 2 'and does not load the spring 7 "'.
  • the two brake blades 8 are in the driving position above the top of the ski, but outside the outline of the ski viewed in plan view, which has certain disadvantages, especially since the ski brake gets caught on one protruding branch or stone is not excluded.
  • the situation is different in the embodiment of the ski brake 1 IV shown in FIGS. 5-8.
  • a housing 2 " is provided, in which a pedal 3 'is mounted on an axle 4.
  • the brake bracket in this embodiment is divided into two brake mandrels 5' which are mirror images of the same the pedal 3 'at its free end does not have a cylindrical bend or cylindrical bore, but a recess 3'b, which has a circular cross-section at both ends, but widens approximately conically in the horizontal longitudinal center plane towards the longitudinal center plane of the pedal 3' , so that pivoting of the end sections 5'a of the two brake mandrels 5 'is possible about the point 3'c.
  • sections 5'c of the two brake mandrels 5' forming the pivot axis of the brake bracket 5 ' are in receiving bores 6'c in FIGS Slidable bearing parts 6 'mounted, which expand outwards in a funnel shape, so that here, too, pivoting of the sections 5'c by a predetermined angle in a parallel plane to the top of the ski is possible.
  • a stop body 12 is formed in one piece with the housing 2 ".
  • each brake mandrel 5 ' Since the supporting surface of section 5'a of each brake mandrel 5 'is in the vicinity of the side wall of pedal 3, the contact points of sections 5'c on shoulders 12a of stop body 12, on the other hand, are in the vicinity of the vertical longitudinal center plane of ski brake 1 IV , there is a pivoting of each brake mandrel 5 'about the point 3'c when the toggle lever system formed from the pedal 3' and the brake mandrels 5 'is pressed into its extended position. At the same time, the section 5'a migrates outwards until the position shown in FIG. 8 is reached, in which the bends adjoining the end sections 5'a bear against the longitudinal side walls of the housing 2 ". In order to allow the sections 5 to slide sideways To prevent 'c from the shoulders 12a of the stop body 12, vertical bolts 11 are arranged on arms 10, which extend from the bearing parts 6' to the vertical longitudinal median plane.
  • the two brake mandrels 5 ' When the toggle lever system is depressed, the two brake mandrels 5 'are pivoted in a plane parallel to the top of the ski.
  • the two brake blades which are fastened to the sections 5'd of the brake mandrels 5 ', come to rest on the top of the ski (see FIG. 8). Since the two brake mandrels 5 'are made of spring steel wire, they are somewhat tensioned when they are brought into the extended position of the toggle lever system, which facilitates their return to the braking position. Since, as has already been stated, the brake blades are in the driving position within the two side surfaces of the ski, the danger is of the brake vanes or the sections 5'd carrying them stuck at an obstacle.
  • the ski brake 1 v shown in the figures mentioned has a housing 2 "'in which a pedal 3" is pivotally mounted on an axis 4'. At the free end of the pedal 3 ", two brake pins 5" made of steel wire are mounted with their upper ends. These brake mandrels 5 “are angled several times and have a section 5" a with which they are mounted in the pedal 3 ", a section 5" b adjoining this, a section 5 "c parallel to section 5" a, which defines the pivot axis of the Brake mandrel 5 ", and a portion 5" d, which carries a brake pad, not shown.
  • longitudinal slots 2 "" c are left in the longitudinal side walls of the housing 2 ", which run parallel to the base of the housing 2"'.
  • the pedal 3 is under the influence of a leg spring 16 which is arranged on the axis 4 'and which tends to pivot the pedal 3" upwards.
  • a hole 3" b is cut out, which in the area of its two ends is circular in a side view, but widened in a wedge shape towards the vertical longitudinal center plane of the housing 2 in a parallel plane to the underside of the pedal, so that a pivoting movement of the sections 5 "a of the brake mandrels 5" is possible.
  • each brake mandrel 5 must be "a sleeve 18 is placed, which slides on the inside of the associated side wall of the housing 2" '.
  • This sleeve 18 is provided with a slot 18a which extends over the entire length of the sleeve and is used to place the sleeve on the section 5 "c of the brake mandrel 5".
  • a groove extends from one end of the sleeve 18 and is intended for receiving the section 5 "b of the brake mandrel 5".
  • the end of the sleeve 18 opposite the groove is bevelled or cylindrically curved in order to facilitate the sliding of the sleeve 18 on the longitudinal side wall of the housing 2 "'. In the area of the two longitudinal slots ZZ2"' c the two longitudinal side walls of the housing 2 " '' curved or angled.
  • the ski brake 1V In the braking position, the ski brake 1V assumes the position shown in FIGS. 9 and 10.
  • the pedal 3 is erected under the influence of the leg spring 16, and the sections 5" c of the two brake mandrels 5 "are located on the left ends of the longitudinal slots 2" 'c.
  • the section 5 "a of each brake mandrel 5" is on the other hand right limit of hole 3 "b.
  • the sleeve 18 'shown in Fig. 13 differs from the sleeve 18 shown in Figs. 9 to 12 only in that it is made of resilient material. For this reason, the slot 18'a is narrower than the diameter of the section 5 "c of the brake mandrel 5". The sleeve 18 'therefore lies under tension on the section 5 "c. The groove 18'b has a width which corresponds to the diameter of the section 5" b of the brake mandrel 5 ".
  • the ski brake 1 VI shown in FIG. 14 is very similar to the last one. It differs from this only in that, instead of sleeves, stops 20 in the form of disks are arranged on the sections 5 "'c of the brake mandrels 5"', which stops slide on the outside of the side walls of the housing 2 IV . Furthermore, a tension spring 21 is arranged between the two brake mandrels 5 "'instead of a compression spring.
  • the invention is in no way tied to the exemplary embodiments shown in the drawing and described above. Rather, various modifications thereof are possible without leaving the scope of the invention.
  • the sections of the brake mandrels used for storage in the elongated holes do not have to be mounted directly in the longitudinal slots. Rather, they can also be stored in sliding blocks which are guided in corresponding guideways in the elongated holes in the side walls of the housing.
