Definitions

  • the invention relates to a device for damping Flex movements of a ski or sliding board, with a damper unit, which two in a longitudinal direction against damping resistance damping elements which can be displaced relative to one another has and on the top of the ski or gliding board is arranged.
  • the damper unit is as double-acting hydraulic piston-cylinder unit, its cylinder and housing relative to flex movements can be moved towards each other, with an adjustable Throttle that hydraulically between two from the piston chambers arranged in the cylinder, hydraulic medium flows from one chamber to the other.
  • Throttle By corresponding adjustment of the throttle can be different Damping resistance can be set.
  • the object of the invention is now in a device of type specified at the beginning in addition to a setting with clear Damping of flex movements of the ski or the like also one To enable setting at which the constructively specified Flex characteristics of the ski or the like. practically completely remains unchanged.
  • This task is accomplished with the device specified at the beginning solved in that the one element of the damper unit on a first on the ski or the like. attached or attachable Abutment held and the other element coupled with another abutment on and off which is in the longitudinal direction away from the first abutment on the ski or the like is attached or attachable.
  • the invention is based on the general idea of the damper unit to arrange on and off by one Damper element mechanically decoupled from the associated abutment or can be coupled with the abutment.
  • one Damper element mechanically decoupled from the associated abutment or can be coupled with the abutment.
  • the damper unit In order to can be on the one hand between the two abutments Switch on damping-effective adhesion by one Damper element in its coupled state with the abutment brought.
  • the other element of the damper unit in the longitudinal direction firmly connected to a coupling part, which with a between two end positions adjustable mating coupling part of the other abutment cooperates, the coupling part in one end position of the mating coupling part in the longitudinal direction held positively relative to the other abutment and in the other end position of the mating coupling part in Is movable in the longitudinal direction.
  • the damper assembly is largely arbitrary, however, according to a preferred embodiment can be trained that so-called counterflex movements of the ski where the ends of the ski or Sliding boards down relative to the bond area swing, be effectively dampened during flex movements, where the ski ends move relative to the binding area move up, not or only slightly damped.
  • the counter coupling part formed as a slide, which in one End position holds a claw of the coupling part positively and releases in its other end position.
  • the counter coupling part is provided in particular train as a rotary valve, which the claw in his engages an end position with a part of its peripheral wall as well as in the longitudinal direction and in its other end position the claw with a recess in its peripheral wall Longitudinal direction releases.
  • the rotary bearing of the rotary valve can be set using a link guide take place outside the axis of rotation is so that for the claw within the peripheral wall of the A correspondingly large space is available stands.
  • damper in such a way that that it is only so-called Counterflex movements of the ski, i.e. Movements of the Ski ends down relative to the ski center area, dampens.
  • Counterflex movements of the ski i.e. Movements of the Ski ends down relative to the ski center area
  • Ski 1 is a first, essentially plate-shaped abutment part 2 arranged lying on the top of the ski.
  • the abutment part 2 is fixed on the ski 1 by means of a likewise substantially plate-shaped holding part 3, which is the right end of the abutment part 2 in FIG. 1 encompasses and with a toothing form-fitting in a counter toothing engages on abutment part 2.
  • the holding part 3 is attached to the ski 1 with screws, not shown.
  • abutment part 4 In the longitudinal direction of the ski from the holding part 3 is on the other Another abutment part 4 at the end of the abutment part 2 arranged, which is attached to the ski 1 with screws 5.
  • abutment part 4 which, like the abutment part 2 and the holding part 3 is made of plastic, is made of metal existing sliding guide 6 embedded, cf. Fig. 2.
  • This sliding guide 6 engages with C-shaped in cross section Wheels facing each other with their concave sides are, correspondingly shaped longitudinal edges of the abutment part 2, which changes when the ski flexes Ski longitudinal direction relative to the sliding guide 6 and the abutment part 4 moves. This is due to the fact that the abutment part 4 vertically away from the neutral bending zone the ski 1 arranged and in the longitudinal direction in a larger Distance from the sliding guide 6 by means of the holding part 3 is recorded.
  • a cylinder designed as a piston-cylinder unit hydraulic Damper 7 arranged under jamming or latching.
  • the Piston rod of the damper 7 is with a coupling part 8 - see.
  • Fig. 3 - connected, which is in a corresponding Longitudinal channel on the underside of the abutment part 2 extends and under a molded on the abutment part 4 Guide plate 9 - cf. Fig. 1 - passes.
  • the coupling part 8 acts with a counter-coupling part 10 together, which in the manner shown below as Rotary valve designed and around a vertical pivot axis S - cf. Fig. 1 - is rotatably supported on the abutment part 4.
  • the elements for the rotary mounting of the mating coupling part 10 are arranged at a distance from the pivot axis S and include essentially one molded onto the abutment part 4 and in Fig. 1 visible arcuate web 11, which in a 4 clearly recognizable groove 12 on the underside of the mating coupling part 10 engages with play in the direction of the arc, i.e. the groove 12 forms a guide link for the web 11, such that the mating coupling part 10 between two End positions can be rotated.
  • the counter coupling part engages 10 the guide plate 9 of the abutment part 4 with a radially outwardly projecting edge 13.
  • the claw-shaped end 15 of the coupling part 8 is inside the recess 14 of the mating coupling part 10 held in the longitudinal direction of the ski, with the result that the piston rod of the damper 7 when flexing the Skis 1 is moved relative to the cylinder of the damper 7 and the damper 7 accordingly one of the flex movements counteracting damping resistance generated.
  • the piston rod of the damper 7 weak in the push-out direction is biased so that it from one in the cylinder crawl out of the damper 7 inserted position examined. This can ensure that the claw-shaped End 15 after a certain delay time again Position in the recess 14 of the mating coupling part 10 assumes and accordingly a rotary adjustment of the counter coupling part 10 with insertion of the locking piece 16 in the bolt recess 17 is made possible.
  • the rotational end positions of the mating coupling part 10 are as locking positions formed, in which, not shown, to the abutment part 4 molded locking elements with locking recesses 20 cooperate on the mating coupling part 10.
  • the top of the left end region in FIG. 1 of the abutment part 4 and the top of the holding part 3 are used for Inclusion of toe-side or heel-side shoe holder assemblies 21 a ski binding. These shoe holder assemblies 21 are indicated by dashed lines in FIG. 1.
  • the invention Device for damping flex movements of a Skis or the like also takes on the function of a stand or Spacer plate for ski binding.
  • damper 7 This is a piston-cylinder unit with a cylinder 22 and a piston 23 displaceable therein formed with a piston rod 24 arranged on one side.
  • the cylinder 22 has a multiply stepped cylinder bore 25 which is at the right in Fig. 5 end of the cylinder 22 into a filling bore coaxial with the cylinder bore 25 26 continues, which is formed in one piece on the cylinder 22 Bottom 27 arranged and through a in the filling hole 26 pressed ball 28 is closed.
  • cylinder bore 25 Within the portion of the cylinder bore adjacent to floor 27 25, which has a slightly smaller diameter than the central portion provided for the piston 23 Has cylinder bore 25 is a compressible foam body 29 with closed porous, gas-filled cell structure and a filling bore 26 which continues coaxially and completely penetrating the foam body 29 Axial bore held by an interference fit.
  • the foam body 29 can consist, for example, of cellular rubber or silicone foam with a density of approximately 0.5 g / cm 3 .
  • At least one throttle gap 30 is formed, over which the cylinder bore parts in front of and behind the piston 23 communicate with each other.
  • a piston 23 arranged axially stepped bore 31, with respect to the Diameter larger section arranged on the piston rod side is such that the opening cross-section is partially covered by a ring step 32 on the piston rod 24 becomes.
  • spherical closing body 33 arranged with which the conical Ring step 34 of the step bore 31 in the manner of a valve seat cooperates, that is, the closing body 33, whose diameter is smaller than the diameter of the Closing body 33 receiving part of the stepped bore 31, and the ring stage 34 form a check valve, which opens at a pressure drop in the direction of the piston rod 24 and closes at the opposite pressure drop.
  • a guide bush 35 e.g. from Delrin 100, for the Piston rod arranged.
  • This bush 35 is axially between an inner cone on the cylinder 22 and a disc-shaped Soil 36 held by a flanged or with the bottom 36 pressed front edge of the cylinder 22 held becomes.
  • the guide bush 35 is on the outside by an O-ring opposite the cylinder 22 and inside by a grooved ring the piston rod 24 sealed.
  • Piston 23 and piston rod 24 are in the example shown connected to each other in that the piston 23 with a centric axial bore on a threaded extension 37 of Piston rod 24 pushed on and by means of a thread extension 37 unscrewed nut 38 against the ring step 32 of the piston rod 24 is tensioned.
  • the damper 7 is completely prefabricated, however, without pressing the ball 28 into the filling bore 26.
  • the piston rod 5 pulled out to the left so that the piston 23 reached its end position on the packing 35. Now the cylinder 22 through the filling bore 26 with hydraulic Medium filled. This filling can if necessary with overpressure. Then the filling bore 26 closed by means of the ball 28.
  • the foam body 29 is increasingly elastically compressed, since the piston rod penetrating into the cylinder 22 24 Hydraulic medium displaced.
  • the foam body 29 forms So a "volume buffer" through which the hydraulic medium kept bubble-free in the cylinder 22 and, if necessary is also kept under constant overpressure, independently on the temperature of the hydraulic medium.
  • piston 23 and piston rod 24 lead relatively to cylinder 22 during flex movements of the ski when the Move the ski ends upwards relative to the binding area, weakly damped pressure strokes. In contrast, counterflex movements occur of the ski when the ski ends are relative Move down to the binding area of the ski, heavily damped Lifting steps.
  • the seal package 35 constantly pressurized. This is beneficial because the sealing elements are always hydraulic on adjacent surfaces of the piston rod 24 or the cylinder 22 are pressed down and remain sealed.
