Definitions

  • the present invention relates to a tensioning device for a ski boot according to the preamble of claim 1.
  • a tensioning device of this type is known, for example, from FR-A 2 561 878 or the corresponding USA 4,631,839.
  • a winding element for winding and unwinding a band-shaped tensioning element and a coaxial transmission member are detachably coupled to one another via a toothing.
  • the transmission member is rotatably guided in a stationary, rotatably mounted cylinder body, but is displaceable in the axial direction.
  • the cylinder body Via a driving connection active in the winding direction of the winding element, the cylinder body is connected to a bearing element which is rotatably mounted in a housing about the axis of the winding element and the tensioning element and on which a lever-shaped actuating element is pivotably arranged about a shaft running at right angles to this axis and intersecting it.
  • the cylinder body and thus the transmission member are prevented from rotating counter to the winding direction by means of a return catch device.
  • a spring presses the transmission member in the opening direction of the clutch against the actuating element, which is formed eccentrically on its periphery in the region of the shaft.
  • the actuating element To wind up the tensioning element, the actuating element is moved out of its rest position, in which it rests against the housing of the tensioning device 90 ° pivoted about the shaft so that it runs approximately in the radial direction with respect to the axis of rotation of the transmission member and the winding element.
  • the coupling to the transmission element and the winding element is always kept closed, since the periphery of the actuating element is cylindrical in the corresponding area to the shaft.
  • the actuating element is pivoted back and forth in a working swivel area, as a result of which the winding element is driven intermittently in the winding direction.
  • the actuating element is pivoted back into the rest position, the clutch being engaged and thus the tension being retained in the tensioning element. If the tensioning device is now to be released, the actuating element is pivoted from the rest position by 180 ° about the shaft, as a result of which the transmission element can be displaced in the direction of its axis of rotation under the force of the spring, since the distance between the periphery of the actuating element and the transmission element lies against it. to the shaft decreases in the area of the second half of this pivoting movement. This opens the clutch and releases the take-up element for turning in the unwinding direction.
  • This known tensioning device is complicated both in structure and in operation.
  • FIG. 1 Another tensioning device with a rotatably mounted winding element for winding and unwinding a cable-shaped tensioning element is known from FR-A 2 593 682 and the corresponding US-A 4,719,670.
  • a shaft protrudes, on which a substantially hollow cylindrical Transfer member sits freely rotatable. This is prevented from rotating against the winding direction by means of a return locking device.
  • the transmission member In the area facing the winding element, the transmission member is disc-shaped and has a recess into which a pin protruding from the winding element engages.
  • the transmission member On the side facing away from the winding element, the transmission member is also disc-shaped and has a further recess.
  • the transmission element is carried along by the driving lug and the winding element by the pin engaging in the recess of the transmission element. If the actuating element is moved counter to the winding direction, the transmission element and thus the winding element is prevented from rotating in this sense by the return latching device, the driving lug disengaging from the corresponding recess.
  • the shaft and thus the winding element are pressed down, for example by means of the ski pole, as a result of which the pin disengages from the corresponding recess in the transmission member. This will release the take-up element.
  • a disadvantage of this tensioning device is that a tool, for example the ski pole, is necessary for loosening.
  • FIG. 1 Another tensioning device is known, for example, from US Pat. No. 4,433,456.
  • This has a drum-shaped winding element for winding and unwinding two tensioning cables, which is permanently connected to a transmission element via a gear transmission.
  • the transmission member and thus the winding element are detachably prevented from rotating against the winding direction by means of a decoupling return catch device.
  • On a thread on the transmission member there is an actuating element as a nut which, when twisted in the winding direction in the axial direction, runs onto a driving stop on the transmission member and drives the transmission member or the winding element in the winding direction.
  • the actuating element To unwind the tensioning cable, the actuating element is rotated counter to the winding direction, which moves away from the driving stop in the axial direction of the transmission member and has a releasing action on the return catch device. As a result, the transmission member and thus the winding element for unwinding the tensioning cable is released.
  • the actuating element In this known tensioning device it is disadvantageous that in order to release the winding element in order to unwind the tensioning cable, the actuating element must be rotated through a large angle. Moreover, it is necessary for the actuating element to be rotated in the unwinding direction to unwind the tensioning cable, otherwise by rotating the transmission element with regard to the actuating element, the return latching device is reactivated and further unwinding of the tensioning cable is prevented.
  • Another tensioning device is known from EP-A 0 255 869. This also has a drum-shaped winding element for winding and unwinding tensioning cables, which is permanently connected to a transmission element via a Maltese, gear or planetary gear.
  • a two-armed locking lever is pivotally mounted with the one lever arm biased in the direction against locking teeth on the housing of the tensioning device.
  • the other lever arm engages in a control curve of an actuating element, which is connected via a driving connection which, when the direction of rotation of the actuating element changes, permits an empty pivoting angle of the actuating element with respect to the transmission element.
  • the control cam When the actuating element is rotated in the winding direction, the control cam releases the latching lever and the driving connection takes the transmission member and thus the winding element in the winding direction.
  • the latching lever engaging in the latching toothing prevents the transmission member and thus the winding element from rotating against the winding direction.
  • the actuating element is rotated counter to the winding direction, as a result of which the control cam now releases the latching lever from the latching toothing and the driving connection takes the transmission member and thus the winding element in the unwinding direction.
  • a twisting of the actuating element by a smaller angle is probably necessary for releasing the locking lever.
  • the actuating element must be used to unwind the tensioning cable be rotated continuously in the unwinding direction, otherwise the control cam releases the locking lever again and thus further loosening of the tensioning cable is prevented.
  • the tensioning device is operated by pivoting the actuating element about a single axis. This simplifies the construction and increases the ease of use.
  • the return catch device preferably has a freewheel which is effective in the winding direction. This enables a practically infinitely variable tensioning of the tensioning element, since freewheels engage immediately when changing the direction of rotation of the transmission element.
  • a particularly preferred and simple embodiment of the tensioning device is specified in claim 3. This means that no special actuator is required to release the clutch.
