Description

  The present invention relates to a bicycle, and more particularly, to a bicycle having a folding function and an auxiliary control handle.

  Conventional bicycles include a front control handle for the driver to control the direction of travel of the bicycle. Some bicycles have a rear control handle that is linked to the front control handle in addition to the front control handle, so that others can assist in controlling the traveling direction of the bicycle later. This type of bicycle is used for riding by children and allows parents to control later.

  For example, in the bicycle disclosed in Patent Document 1, wires are connected to both sides of the bottom end of the front and rear handles. Therefore, when the rear handle is rotated, the wire is interlocked with the front handle, thereby achieving the purpose of auxiliary control.

  In addition, the invention described in Patent Document 2 uses the same principle and further has a foldable function.

  However, in the invention described in Patent Document 2, there is a possibility that the wire may hinder the operation of folding, moving, or folding during folding. Here, in the invention described in Patent Document 3, a split structure is disclosed, and the two wires and the folding portion are split from each other, and the tension action at the time of folding the wire is controlled, and the auxiliary control and the folding function are combined. .

However, all the wires of the invention described in Patent Documents 1 and 2 are exposed to the outside of the vehicle body. Moreover, the division | segmentation structure of the invention described in patent document 2 has a large number of parts other than a vehicle body, and when a surface area and weight become large, storage property worsens.
The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a bicycle that has a reduced number of parts and improved storage.

  The present invention includes a front frame, a front wheel, a rear frame, a rear wheel, a folding part, a first wire, and a second wire. The front frame includes a front control handle, a front rotating portion, a front tube, and a first tube. The front control handle and the front rotating portion are in a relationship in which one rotates when the other rotates, and the front rotation The part is incorporated in the front tube, the first tube has a first tube front end and a first tube rear end, and the first tube front end is connected to the front tube.

When one of the front wheel and the front control handle rotates, the other rotates.
The rear frame includes a rear control handle, a rear rotating portion, a rear tube, and a second tube. When the one of the rear control handle and the rear rotating portion rotates, the other rotates, and the rear rotating portion is located in the rear tube. The second tube has a second tube front end and a second tube rear end, and the second tube rear end is connected to the rear tube.

  The rear wheel is rotatably connected to the rear frame and supports the rear frame.

  The folding part has a front connection unit (unit), a rear connection unit, and a pivot. The front connection unit and the rear connection unit can pivot relative to each other with the pivot as an axis. The rear connection unit is connected to the front end of the second tube.

One end of the first wire is provided in the front rotating part, and the other end is provided in the rear rotating part.
One end of the second wire is provided in the front rotating part, and the other end is provided in the rear rotating part.

  The first wire and the second wire connect the front rotating part and the rear rotating part through the insides of the first tube and the second tube.

  Thereby, it can suppress that a wire exposes outside by letting a 1st wire and a 2nd wire pass inside the 1st tube and the 2nd tube. Moreover, it can suppress that a 1st wire and a 2nd wire gather and interfere when folding. Further, the number of parts of the vehicle body can be reduced as compared with the conventional divided structure, and the structure of the vehicle body can be simplified.

  In addition, for example, a flexible tube and / or an elastic protective covering can be incorporated in the outer peripheral edge of the portion of the first wire and the second wire that are passed through the first tube and the second tube, so that the wire is not worn or worn. Attention pinching can be suppressed.

  Thus, since the 1st wire and 2nd wire of this invention are incorporated in the inside of a 1st tube and a 2nd tube, all are not exposed outside the vehicle body like the prior art. Since the first wire and the second wire are passed through the folding portion, the amount of deformation is reduced, and it is difficult to become a problem of clinging. In addition, since it is not necessary to form a split structure at the bottom of the vehicle body to suppress the winding of the wire, the vehicle body of the present invention is simpler than that of the prior art. In other words, the structure of the present invention is clearly simpler than the conventional bicycle with auxiliary turning control and folding function, and it is expected to reduce the overall weight and meet the needs of the market. Is done.

  The first tube is provided with at least one first through hole, and the second tube is provided with at least one second through hole. The first wire and the second wire are passed from the first through hole and the second through hole into the first tube and the second tube. Furthermore, at least one first outlet hole and second outlet hole are provided at locations adjacent to the folded portions of the first tube and the second tube. The first wire and the second wire are used to pass through the outer side of the folding part through the first consistent hole and the second through hole. Thereby, when the folding part is folded, the first wire and the second wire can be prevented from being damaged by being attached to other parts or being bent excessively.

In addition, the bicycle 1 has a saddle, a saddle tube, a rear fork, a five-way tube, a pedal, a crank, a chain, and a flywheel according to demand. ) Equipped with members that are always seen on the bicycle.

  The front frame 10 includes a front control handle 11, a front rotating portion 12, a front tube 13, and a first tube 14. When one of the front control handle 1 and the front rotating portion 12 rotates, the other rotates, the front rotating portion 12 is assembled in the front tube 13, and the first tube 14 includes the first tube front end 15 and the first tube. It has a rear end 16. The first tube front end 15 is connected to the front tube 13, and the first tube 14 has at least one first hole 17. In addition, the front wheel 20 maintains a relationship with the front control handle 11 in which the other rotates when one rotates.

  The rear frame 30 includes a rear control handle 31, a rear rotating part 32, a rear tube 33 and a second tube 34. The rear control handle 31 and the rear rotating portion 32 are in a relationship in which when one rotates, the other rotates, the rear rotating portion 32 is assembled in the rear tube 33, and the second tube 34 is connected to the second tube front end 35 and the second tube 34. It has a tube rear end 36. The second tube rear end 36 is connected to the rear tube 33, the second tube rear end 36 is directly or indirectly connected to the rear tube 33 (for example, by a rear fork), and the second tube 34 has a second hole 37. . In addition, the rear wheel 40 is rotatably connected to the rear frame 30 and supports the rear frame 30.

  As shown in FIG. 3, the folding unit 50 includes a front connection unit 51, a rear connection unit 52, and a pivot 53. The front connection unit 51 and the rear connection unit 52 are relatively pivoted directly about the pivot 53. The front connection unit 51 is connected to the rear end 16 of the first tube, and the rear connection unit 52 is connected to the front end 35 of the second tube, whereby the front frame 10 and the rear frame 30 are also pivoted on the pivot 53. As a relative pivot and can be folded. The first tube 14 and the second tube 34 are provided with at least one first outlet hole 18 and second outlet hole 38 at a position adjacent to the folded portion 50.
