Description

[Brief explanation of the drawing]

Figure 1 is an overall front view showing a schematic diagram of one embodiment of the present invention, and Figure 2 is an exploded view of the main parts of the horizontal pipe of the first embodiment, consisting of the straight upper pipe and the vertical pipe. FIG. 3 is an enlarged perspective view illustrating the top pipe of the horizontal pipes in the embodiment in FIG. 1, and FIG. 4 shows the front bent part in the embodiment in FIG. 1. An enlarged perspective view showing an example of disassembly, Fig. 5 is an enlarged plan view of the front bent part when the same body is used on a bicycle, and Fig. 6 shows the same body bent into a U-shape to be used as a carrier, a chair, etc. An enlarged plan view illustrating the front folding part in use,
FIG. 7 is an enlarged plan view illustrating a later-generation bending section in which the vehicle body is bent into a U-shape similar to FIG. 6, FIG. Figure 1 is a schematic plan view showing the process of folding the two-wheeled vehicle of the embodiment;
Fig. 11 is a schematic plan view showing the state in which the two-wheeled vehicle in the embodiment shown in Fig. 1 has been completely folded. A schematic plan view illustrating the state, FIG. 12 shows the process of transforming a tricycle into a twin cylinder or twin carrier by bending the tricycle and its front wheel by the composite configuration of the embodiment in FIG. 1, and the structure of the four-wheel vehicle. The schematic plan view shown in FIG. 13 is a schematic plan view showing the process of folding the tricycle of the complex shown in FIG.
