A track laying gear (2, 3) which can be coupled to a wheelchair (1) in particular for negotiating steps, possesses a running gear part (2) having motor-drivable caterpillar tracks (16) and an adaptor (3) for fixing the wheelchair in a backward-tilted driving position. In order to enable the wheelchair driver himself to perform the coupling and uncoupling, and to manoeuvre, the adaptor (3), having an automatic coupling (21) for a corresponding counter-coupling (27) attached to the wheelchair (1), is connected to the running gear part (2) via a lifting device (31 to 36), which can be actuated by the wheelchair driver via actuation or control members (32, 33), optionally to lift the wheelchair (1) relative to the running gear (2) or to lift the running gear with the wheels (9) of the wheelchair remaining on the ground, both in the normal driving position and when the wheelchair (1) is in the tilted position. …<IMAGE>… |
