Abstract
Supporting members with alternating positions (5) are disclosed for raising and lowering bulky transport goods (2). The supporting members (5) are pivotally arranged on a transport structure and can be connected with auxiliary pivoting means. The structure can be lowered onto the floor (9) or into a low position and brought back into a high position by corresponding pivoting movements (6) of the supporting members (5). The supporting members (5) are preferably designed as knee links and their axes of articulation are parallel to the vehicle axles. This new solution can also be implemented by means of centering cones and centering funnels in combination with a device for alternatively moving a vehicle between a standing position and a transport position.
Claims10
A change-over support for moving a load between low and high positions, comprising:
- at least a first strut comprising a first elongated member one end of which is pivotally supported in a plane disposed substantially in the low position, a second elongate member connected at one end to a second end of the first elongated member for limited pivotal movement in a predetermined direction and a third elongated member connected at one end to a second end of the second elongate member for limited pivotal movement in the predetermined direction;
- means at the connection between the second and third elongated members for supporting the load;
- and
- means for connecting a second end of the third elongate member to means for exerting thereon a tractive force for pivoting the first, second and third elongate members in the predetermined direction whereby the first, second and third elongated member comprise a force arm and the first and second elongate members comprise a load arm and the ratio of force arm to load arm diminishes during the movement in the predetermined direction.
