B. is not supported on the backdrop, the translational mobility of the clamping disc is released so that the jamming of the friction wheel canceled and the clamping plate can be transferred to the position below the connecting line.
  • a particularly simple possibility for realizing a translational mobility of the clamping disk is that the clamping disk has a slot and is held in the slot on an axis. With the slot the clamping disc is pivotally mounted on the axle. In the direction of the largest axis of the slot, the clamping disc is also translationally movable. The orientation of the slot in the clamping disc is chosen so that the guide through the gate of the actuating element, in particular the support on the gate of the actuating element, is possible.

  • the pivoting movement of the clamping disk 32 is limited by the clamping disk housing 33. Due to the position above the connecting line 54 described above, this position of the clamping plate 32 is also referred to briefly as the upper position. In contrast, the in FIG. 5 shown position of the clamping disc referred to as the lower position.
  • FIG. 8 shows a configuration of the braking device with braked drum 12.
  • the voltage reached by the withdrawal of the scroll spring 14 acts. With this voltage, the spring 14 tries to rotate the drum 12 in the winding direction and retract the cable again. For a brief moment then rotates the drum 12 and with it the friction wheel 22 in a direction opposite to the previous direction when pulling off the cable direction. Due to the contact between clamping disc 32 and friction wheel 22 caused by the leaf spring 38 and the resulting frictional engagement between contact surface 52 and friction surface 40, the clamping disc 32 is again moved towards the lower position - "the friction wheel 22 would like to return the clamping disc 32 to the lower position take". However, since the brake lever 30 in the in FIG. 7 shown position with its inclined surface 47 of the clamping disc 32 leaves no room for a translational movement, this jammed the friction wheel 22.
