WIPO Patent Application WO/2005/108122
Kind Code:
A1
Abstract:
The invention relates to a manually displaceable transport trolley (1) comprising a chassis (2) that is equipped with front and rear directional steering rollers (8, 9) that adopt a tracking position. Either the front steering rollers (8) or the rear steering rollers (9) are fixed to the chassis (2) with the aid of elements, which respond to the load of the transport trolley (1), in such a way that when the transport trolley is loaded, the pivoting axis (10) of the steering rollers (8) or (9) that are influenced by said elements adopts an inclined position in the direction in which the transport trolley (1) is pushed. The invention is characterised in that the elements are formed by a flexible elastic support part (12) comprising an upper limb (13) and a lower limb (17). The upper limb (13), which is connected to the lower limb (17) by means of a connecting section (16), is fixed to the chassis (2) and the lower limb (17) is designed to support the front steering rollers (8) or the rear steering rollers (9).
