Patent ID: 8915341

Claim:
A current collector for a device that can be displaced along a conductor line in—and opposite to—a traveling direction, the current collector comprising a current collector trolley displaceable along a guide element of the conductor line in a guided fashion and at least one first lever assembly between the current collector trolley and the displaceable device, the at least one first lever assembly including a first drive lever arm, the first end of which can be rotatably connected to the displaceable device and the second end of which is rotatably connected to a second end of at least one first tension lever arm, the first end of which is rotatably connected to the current collector trolley, wherein a first adjustment drive is provided to move the current collector trolley between a retracted position on the displaceable device and an extended position away from the displaceable device, wherein a first locking device is provided to lock the first drive lever arm in a predetermined extended position when the displaceable device is displaced in the traveling direction and wherein a first flexible draw gear element is provided as the first locking device and arranged on the displaceable device and on the first drive lever arm, wherein the draw gear element is tensioned when the first drive lever arm is extended and the current collector is displaced in the traveling direction.
