Description

Section 2 folding device of bicycle having hinge structure

The present invention relates to a folding device of a bicycle, and more particularly to a folding device of a bicycle using a two-section hinge structure.

Recently, many folding bicycles are produced and used to facilitate the movement and storage of bicycles.

The general folding bicycle has a folding structure shown in Fig. 1 (folded state) and Fig. 2 (folded state).

Looking at the structure, the folding structure is a front frame 111 and the rear frame 121, the front frame 111 is connected to the front hinge plate 112 and the rear frame 121 is a rear hinge plate 122 Connected. The clamping is composed of a release lever 173, a rod clamp 171 and a pin clamp 172, the hinge pin 141 is mounted on the top.

Looking at the transition process from the state of FIG. 1 to the state of FIG. 2, the release lever 173 is raised upward by 90 degrees to release the clamping pressure, and the release lever 173 is rotated 90 degrees in the forward direction about the pin clamp. After the rod clamp 171 is separated from the shear hinge plate 111, the rod clamp 171 is lifted upward to separate the pin clamp 172 from the shear hinge plate 111. Then, the rear hinge plate 121 is rotated around the hinge pin 141 based on the front hinge plate 111 to fold the bicycle.

Since the conventional folding function of the bicycle is performed through several steps, the clamp release operation is very inconvenient, and the folding structure of the bicycle is larger than the frame outer size of the bicycle so that the frame folds out of the frame outer surface so that the appearance of the frame is poor. This is a problem and has the disadvantage of not being compact in terms of packages. Like the folding operation, there is an inconvenience that the folding operation must go through several steps.

An object of the present invention for solving the above-described problems, to simplify the folding structure of the bicycle to provide a folding device of the bicycle convenient folding and releasing operation.

In addition, by simplifying the folding structure of the bicycle and in terms of design so as not to protrude out of the outer surface of the frame of the bicycle to enhance the aesthetics from the styling point of view, to provide a folding device of the bike that can be compact in terms of packaging.

The folding device of the bicycle according to the present invention for solving the above problems, one end is integrally formed or connected with the shear-frame of the bicycle and the other end is folded with the second hinge support frame, the first hinge pin on one side A first hinge support frame hinged to the hinge rod by a hinge; A second hinge support frame having one end fixedly inserted into the rear-frame of the bicycle and the other end folded with the first hinge support frame, and hinged to the hinge rod by a second hinge pin at one end thereof; One end is hinged to the first hinge pin and the other end is hinged to the second hinge pin, the hinge rod is rotated using any one of the first or second hinge pin as the rotation axis.

Here, it is preferable that the first and second hinge support frames have a structure that is locked and released by folding pins.

Here, the first and the second hinge support frame is in contact with the end of the pin that is one end of the locking pin and the first and second hinges to be self-locking when unfolded in a folded state. It is preferable that the taper is formed on the support frame.

Here, the folding device of the bicycle having the two-section hinge structure, it is possible to configure another embodiment further includes a clamping rod for implementing the folding lock and release of the first and second hinge support frame.

Here, the clamping rod is implemented to be a position that does not protrude to the outermost surface of the first and second hinge support frame in the state that the bicycle is not folded.

Here, the folding device of the bicycle having the two-section hinge structure is clamped in the direction perpendicular to the folding direction of the first and second hinge support frame, the stopper is mounted on any one surface of the first or second hinge support frame. It is possible to configure another embodiment further comprising a.

Here, the stopper may be implemented to have the same surface as the outer surface of the first and second hinge support frame when clamping.

Here, the first and second hinge support frame has the same outer diameter as the outer diameter of the front and rear frame of the bicycle when fastening to the front and rear frame, the hinge rod is the first in the state that the bicycle is not folded It is preferably positioned so as not to protrude to the outermost surfaces of the first and second hinge support frames.

According to the above-described configuration of the present invention, the folding structure of the bicycle is simplified to provide easy convenience of folding and releasing operation, and in terms of design, it does not protrude out of the outer surface of the bicycle frame, thereby improving aesthetics in terms of styling. As a result, it is possible to provide a folding device of a bicycle that can be compacted in terms of packaging.
