Document Type and Number:
Japanese Patent JP2005517571
Kind Code:
A
Abstract:
The present invention relates to an arrangement in a wheel lifting mechanism designed to lift at least one wheel ( 1 ) running on an underlying surface so that it is capable of negotiating an obstacle (h) rising above the underlying surface. The arrangement comprises an element ( 7 ) which is formed with a contour convexly curved towards the underlying surface and is moveably supported in relation to the axle of the wheel ( 1 ). The said element is designed, when the contour of the element ( 7 ) engages with the obstacle (h), to bring about the said lifting of the wheel ( 7 ) as the element ( 7 ) is rotated about its point of engagement with the obstacle (h). The arrangement further comprises a chassis ( 4 ), to which the wheel axle is firmly connected. Between the chassis and the element ( 7 ) there is an operative connection designed, when the element ( 7 ) engages with the obstacle (h), to allow the chassis ( 4 ) firstly to undertake lifting of the wheel ( 1 ) from a home position of the element ( 7 ) during a displacing movement relative thereto in the direction of movement of the wheel, and secondly to bring about a return to the home position once the wheel ( 1 ) has been lifted to the level of the obstacle (h).
