The folding trailer, with four types A-B-C-D for the transportation of two wheel motorcycles, has two main parts. One part is the web and it consists of four parts (25,27,29,23). The unfolded assembly of these parts has the form of a "U" channel. This assembly opens and closes lengthwise, firstly by means of joints (1,2,3,4) fitted at the ends of the four parts: part (25) folds within part (27), whereas part (23) folds onto part (29) and then both these couples (25,27) and (23,29) slide into each other. The entire assembly is connected to the second part, the suspension frame (33). In the case of type C, the frame (33) unfolds to the sides of part (29) and the wheels of the folding trailer are fitted onto this frame (33). The wheel axles are trapped within the hubs (2) of the frame (33) by means of two yokes (1) (safety pins) for frequent mounting, dismounting of the wheels. Figure 1 illustrates the trailer, fully developed, ready to receive the motorcycle. The motorcycle is secured starting with the front belt figure 1 (a) to the front wheel and then belts (b,c) to the top part of the rear wheel, where we wind a small belt with loops for the clamps (tighteners) (d,e) for the safe transportation of the motorcycle.
Figure 28 illustrates the trailer folded and ready for storage.
