The Fiji agricultural sector

A support structure has a folding leg movement based upon a "scissors" mechanism, one section of which is pivoted to a support frame, and the other section to a link member also connected to the frame. A diagonal latch locks the extended position of the structure by fixing the position of the junction between the link and the latter leg section. A tension spring neutralizes the weight of the structure by interconnecting the upper extremities of the "scissors" configuration. This spring is also used as a guide for the diagonal latch. The folded position of the structure is secured by interengaging a part of the leg system with the frame so that the unit can be stored vertically. Full wheel support is provided in the folded position, and partial wheel support in the extended position.
