Definitions
- the invention relates to a device for influencing bending movements of a ski, with a pushing part arranged or attachable in the longitudinal direction of the ski, which has a section arranged or attachable in the manner of a ski and a region spaced therefrom in the longitudinal direction of the ski and displaceable in the longitudinal direction of the ski, with an area which is fixed or attached to the ski attachable abutment is coupled or coupled via power transmission means.
- the push part is designed to be bendable in the manner of a flat band, one end of the flat band being held ski-like underneath the heel-side binding unit and the other end movable in the longitudinal direction of the ski being guided in ski-fixed guides below the toe-side binding part.
- the front end of the flat band-like thrust part shifts in the longitudinal direction of the ski relative to the top of the ski, because the thrust part lies outside the neutral bending zone of the ski.
- the front end of the pushing part is now supported by spring-loaded tongues on an adjustable abutment on the ski side, with the result that the ski is stiffened in a controllable manner.
- the object of the invention is now to provide a construction which can be easily adapted to different force transmission means in a device of the type specified at the outset.
- a translation device is interposed between the force transmission means and the displaceable area and transmits the movement stroke of the displaceable area relative to the ski to the force transmission means with a predetermined or predefinable transmission ratio.
- the invention is based on the general idea of changing the extent of the effective displacement stroke of the displaceable region of the thrust part by means of a gear arrangement in order to enable an optimal adaptation to the respective force transmission means.
- a hydraulic steamer is to be effective between the displaceable area of the thrust part and the ski-fixed abutment.
- Such steamers are much easier to tune when large lifting movements occur.
- the invention be used hydraulic dampers to implement the stroke of the displaceable portion of the thrust part in an enlarged stroke of the shock absorber.
- FIG. 1 is a schematic plan view of a first embodiment
- Fig. 3 is a plan view of the underside of a second embodiment
- Fig. 4 is a perspective view of the second embodiment.
- a flat band-like thrust part 2 is arranged on the top of a ski 1, the right end of the thrust part 2 in the drawing being arranged in a ski-like manner and for this purpose, for example, screwed to the ski.
- the left end of the pushing part 2 in FIG. 1 is designed as a free end and accordingly shifts relative to the ski 1 in the long ski direction when the ski 1 is bent. This is based on the fact that the thrust part 2 is arranged outside, and above, the neutral bending zone of the ski 1.
- the left free end of the thrust part 2 is connected to a slide 3 or is formed as such, which is slidably received in a ski-fixed guide 4 in the longitudinal direction.
- This leadership essentially exists from a plate 4 'fastened on the upper side of the ski and U profiles 4 "formed on the long edges of the plate 4', which face each other with their concave sides. Long edges of the slider 3 protrude into these U profiles 4" so that the slide 3 can only be moved in the long ski direction.
- a bearing pin 5 is arranged which pivotally supports a double-armed lever 6.
- This lever 6 is articulated with a short arm on the slide 3, a pivot pin 7 arranged on the slide 3 projecting into an elongated hole 8 on the lever 6.
- the longer arm of the lever 6 is connected in an articulated manner to a plunger 9, which forms the piston rod of a hydraulic steamer 10 arranged fixedly on the guide 4.
- a hinge pin 11 fastened to the plunger 9 projects into a further elongated hole 12 on the lever 6.
- the elongated holes 8 and 12 ensure that the lever arms of the lever 6 are able to pivot freely when the plunger 9 and slide 3 are moved in the longitudinal direction of the ski.
- a collar 13 is arranged on the plunger 9, which serves as a plunger-side abutment of a helical compression spring 14 concentric with the plunger 9, the other end of which is supported on the facing end face of the steamer 10.
- the plunger 9 is pulled out of the housing of the steamer 10 when the ski 1 makes a bend in which the ski ends move in an upward direction relative to the center of the ski.
- the helical compression spring 14 arranged concentrically with the plunger is increasingly relaxed.
- the plunger 9 is pushed into the steamer, at the same time the helical compression spring 14 is increasingly tensioned.
- the plunger 9 can be moved comparatively easily in the rebound stage, ie with a displacement m FIG. 1 to the right, while a movement in the compression stage, ie m FIG. 1 to the left, a greater resistance occurs. Accordingly, bending movements of the ski 1 are not or only weakly damped, while increased bending occurs during the bending back. In principle, however, a different tuning of the steamer 10 is also possible, such that increased damping occurs in the rebound stage or the rebound and compression stages have the same damping effect. In this way, bending movements of the ski 1 can then be intensified or steamed in the same way as backbends of the ski 1.
- the thrust part is designed as a rigid base plate 20 for a ski boot, not shown, which is held on the base plate 20 by heel-side and toe-side binding units, not shown, arranged thereon.
- the right end of the base plate 20 in the drawing is on the ski with screws or the like. firmly held, which are used in screw punches 15.
- the left end of the base plate 2 in the drawing is displaceably guided in a 40 m long ski direction.
- This guide 40 which is fixedly arranged on the ski 1, in principle resembles the guide 4 in FIGS. 1 and 2.
- the guide 40 has lateral U-profiles 40 "into which the base plate 20 with longitudinal longitudinal webs molded onto it engages slowly.
- openings 41 are arranged on the U-profiles 40 of the guide 40, into which rocker arms 42, which extend essentially in the direction of the ski, project, which extend between the plate 40 ' Guide 40 and the base plate 20 are arranged and facing each other with their free ends, the aforementioned openings 41 forming the pivot bearings of the rocker arms 42.
- rocker arms can be designed as flat ribbon-like parts with a flat ribbon plane parallel to the top of the ski 1.
- projections are arranged on the underside of the base plate 20, for example in the form of pins 43, which lie laterally on each rocker arm 42 between its ends.
- the end of the base plate 20 held in the guide 40 moves in the longitudinal direction of the ski.
- the projections or pins 43 press the rocker arm 42 by pivoting against the buffer part 44, so that the piston of the steamer 10 is inserted into the steamer cylinder 10 '. Since the projections or pins 43 on the rocker arms 42 m engage a greater distance from the free ends of the rocker arms 42 which are in contact with the buffer part 44, the piston rod of the steamer 10 carries out a lifting movement, the dimension of which is significantly greater than the dimension of the relative displacement. slide between the base plate 20 and the guide 40. The extent of the stroke ratio is determined by the ratio between the length of the rocker arm 42 and the distance of the respective projection or pin 43 from the pivot bearing (opening 41) of the rocker arm 42.
- the rocker arms 42 can also be articulated at their mutually facing ends, e.g. through a film hinge if the rocker arms consist of plastic according to an advantageous embodiment.
