发明名称 AN ARRANGEMENT IN CARRIAGES WHICH MOVE ON WHEELS ALONG A CARRIAGE SUPPORTING SURFACE
摘要 The invention relates to an arrangement for manually steering and manoeuvering a trolley (2) during movement of the trolley on wheels (3, 4, 6) along a trolley supporting surface (1). At least one of the trolley wheels (6) is arranged for pivotal movement via a steering column (7) having a central rotational axis line (8), such as to steer the trolley during its movement along the supporting surface (1) in dependence on a selected pivot position. The arrangement further comprises a steering device (9) which co-acts non-rotatably with the steering column and with the pivotable wheel (6), which is driven by a wheel drive arrangement connected to the wheel. The steering device (9) includes a manually gripable stick (12) or handle located to one side of the rotational axis line (8). The handle or stick (12) is located forwardly of the rotational axis line when the trolley moves in a forward direction. The steering column (7) and its rotational axis line (8) extend vertically or substantially vertically. The stick (12) is pivotably, displaceably and/or tiltably connected to an upper support (13) rigidly connected to the steering column, so as to activate the wheel drive arrangement (10) to drive the wheel (6) in response to the non-neutral setting of the stick (12). The stick (12) and the steering column (7) can be rotated freely (through 360 DEG ) in both directions thus acting as a new type of joy stick function.
