FIG. 3 is an explanatory diagram illustrating an example when the bicycle 100 is transported. FIG. 4 is an explanatory view illustrating an example of the top tube of the bicycle 100. FIG. 5 is an explanatory view illustrating an example of a method for fixing the top tube of the bicycle 100. FIG. 6 is an explanatory diagram for explaining an example of a folding method of the bicycle 100. FIG. 7A is an explanatory diagram illustrating an example of the handle fixing member 17 of the bicycle 100. FIG. 7B is an enlarged explanatory view illustrating an example of the handle fixing member 17 of the bicycle 100. The configuration of the bicycle shown in FIG. 1 and the like is an example, and the present invention is not limited to the bicycle shown in FIG.

  As shown in FIG. 1 and FIG. 2, the bicycle 100 according to the present invention can bend the top tube 10 to save space (M0 in FIG. 1). The bicycle 100 according to the present invention includes at least the top tube 10 as a frame that plays a role of supporting the weight of the rider by connecting the front and rear wheels.

  As shown in FIG. 2 (b), the bicycle 100 according to the present invention can stand on its own in a folded state using a base member 16 (described later) (M3 in FIG. 2). At this time, as shown in FIG. 2B, the bicycle 100 according to the present invention accommodates the pedal (M2 in FIG. 2) and rotates the base member 16 by 90 degrees with respect to the seat post (FIG. 2). M3), can be independent.

  As shown in FIG. 3, the bicycle 100 according to the present invention tilts the bicycle 100 as a whole by pushing and pulling the handle in a folded state (M4 in FIG. 3) and transports it using wheels. (M5 in FIG. 3). The bicycle 100 according to the present invention can be transported like a suitcase. That is, the bicycle 100 according to the present invention can stand up in a folded state and can be transported in a folded state. Note that the handle 100 may be Y-shaped so that the bicycle 100 can be easily transported by grasping the center of the handle.

  Each configuration will be described below.

  As shown in FIG. 4, the top tube (10 in FIG. 1) is connected to the first frame 11 on the saddle side, the second frame 12 connected to the first frame 11, and the second frame 12 in this embodiment. And a substantially cylindrical fixing member 14A, 14B for fixing the positions of the first frame 11, the second frame 12, and the third frame 13. Note that the bicycle 100 according to the present invention may have one fixing member. Further, the fixing member may be a quadrangular column or a polygonal column.

  As shown in FIG. 4, the first frame 11 includes a substantially circular insertion opening 11S. The second frame 12 includes a substantially circular through-hole 12S. The third frame 13 includes a substantially circular arrangement opening 13S in which the fixing members 14A and 14B are arranged. In the bicycle 100 according to the present invention, when riding a bicycle, the fixing members 14A and 14B arranged in the third frame 13 are passed through the through-hole 12S of the second frame 12, and the fixing members 14A and 14B penetrated through the through-hole 12S are the first. It is inserted into the insertion opening 11S of one frame 11 (M6, M7 in the figure). Thereby, the bicycle 100 according to the present invention can fix the positions of the first frame 11, the second frame 12, and the third frame 13 and be able to ride the bicycle. Here, as shown in FIG. 5, the bicycle 100 according to the present invention may fix the positions of the fixing members 14 </ b> A and 14 </ b> B with the attachment members 15 </ b> A and 15 </ b> B. A known technique can be used as a method of fixing the positions of the fixing members 14A and 14B by the attachment members 15A and 15B.

  As shown in FIG. 4, when the bicycle 100 according to the present invention is folded, the fixing members 14A and 14B are accommodated in the arrangement opening 13S of the third frame 13 so that the first frame 11 and the second frame 12 are substantially omitted. The second frame 12 and the third frame 13 are bent at approximately 90 degrees by bending at 90 degrees. Specifically, as shown in FIGS. 6A to 6D, the bicycle 100 according to the present invention rotates and removes the hook member 11A rotatably attached to the first frame 11 when the bicycle is folded. As shown in FIGS. 6E to 6G, the third frame 13 is arranged in the recess at the tip of the hook member 11A, and the first frame 11 and the third frame 13 are connected. Thereby, the bicycle 100 according to the present invention can maintain a folded state.

  As shown in FIG. 2 (a), when the bicycle 100 according to the present invention is folded, the saddle is moved downward (M1 in the figure), the pedal is folded (M2 in the figure), and the seat of the saddle. The base member 16 attached to the lower end of the post (so that it can rotate 90 degrees with respect to the seat post) is taken out (M3 in the figure). As a result, the bicycle 100 according to the present invention can place the pedestal member 16 on the ground in a folded state, and can ensure a stable self-supporting state at three points of the front wheel, the rear wheel, and the pedestal member 16 ( Can support folding bikes).

  As shown in FIGS. 7A and 7B, the bicycle 100 according to the present invention moves the fixing members 14A and 14B forward (M9 in the figure) when the bicycle is folded, so that the handle fixing member 17 It can be inserted into the insertion portion 17a. Thereby, the bicycle 100 according to the present invention can prevent the handle from rotating when the bicycle is folded. The bicycle 100 according to the present invention can prevent the handle from rotating during bicycle transport, and can be transported easily.

  As described above, according to the bicycle (foldable bicycle) according to the present invention, the bicycle can be self-supported in the folded state and can be transported in the folded state. Moreover, according to the bicycle (foldable bicycle) according to the present invention, even a heavy bicycle such as a bicycle with an electric assist can be easily made to stand in a folded state and can be easily transported in a folded state. can do.

  As mentioned above, although embodiment which concerns on this invention was described, this invention is not limited to said embodiment. That is, the present invention can be variously modified, changed, or arbitrarily modified based on the contents described in the claims for utility model registration.
