Abstract
A folding boat having a T-shaped structure, capable of folding by means of folding supports which enable free movement of the structural parts, either the retaining studs, drawbar arms or rear axle shafts, so as to make its folding process much more practical and faster, as well as for more comfort while carrying it by means of the inclusion of a secondary axle for wheel coupling once the trailer has been used, thus obtaining a much smaller structure size after folding than when unfolded.
Description
Figure 3 shows the abovementioned folding supports in further detail, with their res seQtlve feat res and location within the trailer structure.
Figure 4 is a cross sectional wiew of the corner folding support.
Figure shows the unfolded trailer structure on the corner folding support, before being folded.
Figure 5-B shows the direction in which the structure is articulated and folded on the corner folding support.
Figure 8-Ά shows the unfolded trailer structure on the T-shaped folding support.
Figure 8-8 shows the direction in which the structurai parts are articulated and folded on the T-shaped folding support.
Figure 7~A shows the unfolded trailer structure on the tilted, folding. support.
Figure 7-B shows the direction In which the structure is articulated and folded on the tilte folding support.
Figure ~A shows the unfoldect trailer structure on the middle folding support.
Figure 8-B shows the direction in which the structural parts are ar eulated and folded on the middle folding support
Figure ¾ shows, in accordance with an alternative embodiment of the invention, an unfolded pivoting support coupled with one of the structural studs.
Mow, wit referenc to the Figures, i can be seen that the invention consists of a folding trailer, whose folding is obtained by articulating its parts by rneans of the abovementioned folding supports.
