TROLLEY INTENDED FOR A MEDIACL APPARATUS AND COMPRISING WHEELS PROVIDED WITH A CABLE PUSHER

摘要

A trolley intended for a medical apparatus and comprising wheels (19, 21) for displacement on a floor surface (61). In order to push aside cables running on the floor of the working environment, the wheels (19, 21) are provided with a cable pusher (43) having a pushing edge (44). The plate (43) constituting the cable pusher is provided with approximately triangular cut-outs which receive stationary cams. If no external forces act on the plate (43), it is pressed onto the cams by springs in such a manner that the apex (52) of the triangular cut-outs (45) bears on the cams. The springs are proportioned so that an obstructing cable is pushed aside by the plate (43); however, when this plate comes into contact with a fixed obstacle, for example a threshold, the plate is pushed upwards. Damaging of the cable pusher is thus avoided and the risk of overturning of the trolley is reduced.
