Mobile unit for the movement of a load carrier, for example wheelchair, over stairs

摘要

The invention is concerned with the arrangement of a switch on mobile units (1) for the movement of load carriers (5), for example a wheelchair, over stairs. For this purpose, the mobile unit (1) is equipped with motor-driven crawler tracks (3). Provided as a pull grip (11) on the inside of a handle part (4) is a switch arrangement (10) which acts by means of a Bowden pull (14) on the motor drive of the crawler tracks (3), in order to move the mobile unit (1) backwards or forwards. Locating the switch arrangement (10) on the inside prevents the switch (20, 11) from becoming inoperable during the backward movement of the mobile unit (1) in the event that the operator comes up against a wall. <IMAGE>
