  • deformable chambers are filled with a damping fluid.
  • two independent compensation chambers arranged, one of which is adjustable Throttle passage connected to a deformable chamber is.
  • Throttle passage connected to a deformable chamber is.
  • creating damping fluid via the throttle passages into the compensation chambers displaced or from these into the deformable chambers is conveyed back and according to the throttling effect the bending vibrations are damped.
  • the invention has for its object a ski, in particular to create a jump ski that is effective Dampening of vibrations occurring at the ski ends allows.
  • this object is achieved by a vibration damper solved, the one filled with a damping medium Damping chamber, which depends on the bending of the Skis changes volume, and has an opening through which Damping medium can escape from the damping chamber, one with a damping medium under excess pressure filled pressure accumulator is provided to which the Damping chamber can be connected via a valve.
  • the vibration damper according to the invention has the advantage that the damping forces counteracting the vibrating mass due to the overpressure of the stored damping medium be determined and not by the change in volume of the Damping chamber are dependent only.
  • a damping medium can therefore also serve a gas, because the compressibility of Gases from the supply correspondingly larger, the pressure accumulator removable gas quantities balanced under higher pressure can be.
  • the use of a gas as a damping medium ensures a low weight the damping device, what for the design of a Jumping ski is particularly important.
  • Vibration damper according to the invention can be seen in that the desired damping force is generated very quickly can and to build up the damping force also a deformation phase of the ski can be used where the Volume of the damping chamber increases. That way it is possible, the entire displacement stroke of the damping chamber to use for vibration damping.
  • Actuation of the valve to connect the damping chamber to the accumulator can be done in different ways either arbitrarily by the ski jumper or automatically depending on certain load conditions or external influences.
  • the relief of the ski or the lifting of the ski from its course when jumping off the jump from one Sensor detects and the corresponding signal from the sensor is used the damping chamber with the pressure accumulator to control connecting valve in open position.
  • the control of the valve is to be designed so that the Valve is closed again at the appropriate time.
  • a timer can be provided, for example, which activates simultaneously with the opening of the valve becomes.
  • Another way is with help a pressure sensor to the pressure in the damping chamber monitor and the valve depending on a pressure signal to control in the closed position.
  • a pressure sensor to the pressure in the damping chamber monitor and the valve depending on a pressure signal to control in the closed position.
  • a sensor which the bending vibration of the ski is detected, provided. In this case, the control of the pressurization of the Damping chamber depending on the vibration behavior of the ski.
  • Valve mechanical sensors and control means provided his.
  • an adjustable valve can exit have to the damping effect of the vibration damper to be able to influence in addition.
  • the setting this valve is preferably done by hand, but it can an electrically controllable valve can also be provided, which can be controlled depending on the vibration.
  • the vibration damper according to the invention can on the ski arranged or integrated into the ski.
  • the damping chamber preferably has a movable wall, for example a piston or a membrane on the one pushing and / or pulling force transmission member in such a way is coupled to a deformable end region of the ski that a bend in the end portion to a chamber volume changing movement of the movable wall leads.
  • a movable wall for example a piston or a membrane on the one pushing and / or pulling force transmission member in such a way is coupled to a deformable end region of the ski that a bend in the end portion to a chamber volume changing movement of the movable wall leads.
  • At the Movable wall can also be supported by resilient means be the the movable wall after the the resilient Mean opposite movement to the starting position Press back. This is necessary, for example, if the movable wall via a rope to the end area of the ski is coupled.
  • Figure 1 shows a jump ski 1, with two vibration dampers 2 is equipped.
  • the two arranged side by side Vibration damper 2 each consist of an middle area of the ski 1 arranged damping chamber 3 and one limiting the damping chamber 3 and in this axially movable piston 4, which has a piston rod 5 with the front end area of the jump ski 1 firmly connected is.
  • the vibration damper 2 are so arranged that bending vibrations of the front end region the jump ski 1 axial movements of the pistons 4 in the damping chambers 3 result.
  • Both damping chambers 3 are connected to one another via a line 6 connected and to an adjustable throttle valve 7 connected, its output in connection with the atmosphere stands.
  • both damping chambers 3 are one Valve 8 connected to a pressure accumulator 9.
  • the accumulator 9 can be integrated in the jump ski 1 and for Fill with a pressurized damping medium have a filling connection 10 with a check valve 11.
  • a pre-filled with damping medium interchangeable pressure storage cartridge can be provided when attached to the jump ski with the entrance of the valve 8 is connected.
  • the valve 8 is closed in its basic position, whereby the connection between the pressure accumulator 9 and the Damping chambers 3 is locked.
  • the valve 8 is in an open position movable, in which there is the pressure accumulator with the damping chambers 3 connects, causing print media from the accumulator 9 can get into the damping chambers 3.
  • the actuator 12 can by means of electrical, hydraulic, pneumatic or mechanical energy.
  • One is preferred for controlling the actuating device 12 electronic control device 13 provided, which depending on the signal from a sensor 14 Actuator controls.
  • the sensor 14 detects the Jump ski loaded by the ski jumper and transmitted a signal to the control device 13 when at Jump from the ski jumping hill 1 is relieved.
  • the damping medium used in the described damping device a gas, for example compressed air, is used.
  • the pressure accumulator 9 is up to the required Working pressure filled with the gas and the throttle valve 7 set.
  • the damping chambers 3 are continuous with the Atmosphere connected.
  • the pressure in the damping chambers 3 corresponds to the atmospheric pressure.
  • the valve 8 is closed. Remains on the hill during the start-up phase the damping device in the stated state, since the sensor 14 registers the load on the jump ski 1. If the ski 1 is relieved when jumping, so becomes the control device by the signal of the sensor 14 13 activated, whereby this actuating device 12 controls which opens the valve 8.
  • the control device 12 contains a timer activated by the signal from the sensor 14, which the duration of the opening of the valve 8 and thus the Pressurization of the damping chambers 3 on one suitable value. After closing the valve 8 is by escaping the inflowing gas over the Throttle valve 7 the pressure in the damping chambers 3 is reduced and accordingly the damping force takes the value 0 on.
  • the device described for vibration damping can of course in an analogous manner to dampen the Bending vibrations of the rear end of a jump ski be used by appropriately controlled vibration dampers 2 be arranged so that they are on the rear Act on the end of the jump ski.
  • FIG. 2 shows a jump ski 15 with a mechanical Vibration damper 16.
  • the vibration damper 16 has near the binding on the jump ski 15 longitudinally displaceable mounted housing 17, which by a rope 18th or a pole with the rear end of the jump ski 15 is firmly connected.
  • the housing 17 In the housing 17 there are two compression springs 19, 20 arranged with their facing each other Ends at an axially movable between them Spring cup 21 are supported.
  • the stronger compression spring 19 is between an end wall of the housing 17 and the Spring cup 21 clamped with great bias, the Spring cup 21 from a pivotally mounted on the housing 17 Latch 22 is held.
  • the compression spring 20 has a low pretension and therefore holds the ropes 18, 23 excited.
  • the bar 22 solved. This can be done either by hand through the Ski jumper or automatically by relieving the ski or the binding carrier plate. By releasing the latch 22, the locking of the spring cup 21 is released, so that the biased, stronger compression spring 19 the spring cup 21 Push the compression spring 20 so far can until the spring cup 21 on the spring plate 24 supports. In this process, the through increases Ropes 18, 23 acting on the end regions of the jump ski 15 Strength and causes a significant reduction the reverberation of the end regions after the jump from the hill. At the same time, the end areas are covered by the Force of the compression spring 19 in a favorable for the flight phase Situation stabilized.
