The conventional bicycle frame is composed of a head tube, a seat tube, a top tube, a down tube, a seat stay, and a chain stay.

The head tube is connected to the steering wheel linkage at the upper end thereof, and the front wheel rotation linkage is connected at the lower end thereof. The seat tube is connected to the saddle linkage member at the upper end thereof and the chain drive member is connected to the lower end thereof.

The top tube and the down tube connect and support the head tube and the seat tube, and the seat stay and the chain stay connect and support the seat back tube and the seat back tube.

On the other hand, the bicycle frame may have both a top tube and a down tube, but occasionally one main tube may be connected between the head tube and the seat tube.

The structure of such a conventional bicycle frame may be suitable for maintaining the rigidity of the bicycle itself, but there is a problem that shocks and vibrations transmitted from the bicycle wheel are directly transmitted to the bicycle user.

Particularly, in bicycle traveling, the shock and vibration transmitted from the rear wheel is more severe than the front wheel, and this is transmitted to the user through the seat stay.

In recent years, a spring type shock absorber and a hydraulic shock absorber are mounted on a bicycle frame. However, the spring type shock absorber is heavy in weight and does not move smoothly, resulting in a reduction in the buffering force. The hydraulic shock absorber is expensive, . Therefore, there is a need to improve this.

Particularly, the bicycle 2 forms an outer shape by the support frame 30 and the connection frame 20. The support frame 30 serves to support a load from the user sitting on the saddle 8 against the front wheel 4 or the rear wheel 6. [ Thus, the support frame 30 is disposed so as to stand upright. Of course, one or more support frames 30 are provided. The connection frame 20 serves to reinforce the support frame 30 by connecting the support frames 30 disposed upright. Of course, one or more connecting frames 20 may be provided and may be formed in various ways.

In particular, the support frame 30 and the connection frame 20 are made of a rigid material and can be connected in various ways. More specifically, the support frame 30 and the connection frame 20 are made of a metal material having high durability.

The user grasps the steering wheel 10 extended to the support frame 30 or the connecting frame 20 to steer. Therefore, the support frame 30 connected to the front wheel 4 of the bicycle 2 receives a large load.

Therefore, the support frame 30 connected to the front wheel 4, or all the support frames 30, must be buffered.

Accordingly, the support frame 30 is divided into the first frame 110 and the second frame 120. The support frame 30 supported by the front wheel 4 is divided into the first frame 110 and the second frame 120 for convenience.

That is, the first frame 110 connects the wheels 4, 6 or transfers the load to the wheels 4, 6. For convenience, the first frame 110 is directly connected to the front wheel 4. Of course, the first frame 110 can be deformed into various shapes.

The second frame 120 is disposed in a straight line on the first frame 110 and supports a load applied to the saddle 8 or the like. For convenience, the second frame 120 is shown connecting and supporting the handle 10. Of course, the second frame 120 can be deformed into various shapes.

Further, the second frame 120 is buffered with respect to the first frame 110. That is, the buffer 130 functions to buffer the second frame 120 with respect to the first frame 110. At this time, the second frame 120 is buffered with respect to the first frame 110 in a non-contact manner while being spaced a predetermined distance from the first frame 110 in the axial direction.

The buffer 130 includes a first magnet member 132 and a second magnet member 134.

The first magnet member 132 is provided at the end of the first frame 110 facing the second frame 120. Since the first magnet member 132 is made of a magnetic material and the first frame 110 is made of a metal material, the first magnet member 132 can be attached to the first frame 110 simply, 1 frame 110 and fixed.

Then, the first magnet member 132 exerts a magnetic force of a specific polarity.

The second magnet member 134 is provided at the end of the second frame 120 facing the first magnet member 132. Since the second magnet member 134 is made of a magnetic material and the second frame 120 is made of a metal material, the second magnet member 134 can be simply attached to the second frame 120, 2 frame 120 and fixed.

In addition, the second magnet member 134 exerts a repulsive force with the first magnet member 132. Thus, the second frame 120 is buffered in a noncontact manner with respect to the first frame 110. Of course, the number and size of the first magnet member 132 and the second magnet member 134 are not limited.

On the other hand, the first magnet member 132 and the second magnet member 134 must be disposed in a straight line in the axial direction of the first frame 110 to generate a maximum repulsive force.

Thus, the first magnet member 132 and the second magnet member 134 must be protected so as to be arranged in a straight line. In one embodiment, either the first frame 110 or the second frame 120 extends the sleeve 136 to enclose the first and second magnet members 132, 134. For convenience, the sleeve 136 extends through the sleeve 136 of the first frame 110. As a result, the first magnet member 132 is fixed in the sleeve 136 and the second magnet member 134 is linearly reciprocated along the inner surface of the sleeve 136.

Of course, the sleeve 136 is applicable in a variety of shapes and is fixedly mounted to the first frame 110. The sleeve 136 is made of a non-metallic material so that the second magnet member 134, which is reciprocated, is not attached. The sleeve 136 is fixedly connected to the first frame 110 in various manners.

Further, the sleeve 136 may have a stopper 137 protruding from the inside thereof. One of the first frame 110 and the second frame 120 is hooked by the stopper 137 to prevent the first frame 110 and the second frame 120 from completely separating from each other. For the sake of convenience, the latching jaw 139 is formed to protrude from the second frame 120.

Therefore, the second magnet member 134 and the second frame 120, in which the repulsive force is generated and pushed by the first magnet member 132, are prevented from completely separating from the sleeve 136. At this time, the stopper 137 and the stopping jaw 139 may be variously deformed, and the stopping jaw 139 may be formed on the second magnet member 134.

FIG. 5 is an exploded perspective view of a shock absorber of a bicycle according to a second embodiment of the present invention, and FIG. 6 is a sectional view of a shock absorber according to a second embodiment of the present invention.

5 and 6, a shock absorber of a bicycle according to a second embodiment of the present invention includes a first frame 110, a second frame 120, and a buffer 130.

The first frame 110, and the second frame 120 are replaced with those described above.

The side magnet member 138 serves to prevent the sleeve 136 from being damaged by the first magnet member 132 or the second magnet member 134 being reciprocated by the repulsive force against the sleeve 136 do.

That is, the side magnet member 138 is formed on the first magnet member 132 or the second magnet member 134 so that the corresponding second magnet member 134 or the first magnet member 132 is inserted It serves as a guide. The side magnet member 138 is shown extending along the edge of the second magnet member 134 in the direction of the first magnet member 132 to insert the first magnet member 132 for convenience. Of course, the first magnet member 132 is formed in a protruding shape or a conical shape so as to be inserted into the side magnet member 138. At this time, the side magnet member 138 is formed to correspond to the shape of the first magnet member 132 to minimize the swinging of the first magnet member 132.

Accordingly, the sleeve 136, which is a non-metallic material, does not collide with the second frame 120 of the metallic material, which is reciprocated by the side magnet member 138, and the second magnet member 134 which is magnetized.

At this time, the side magnet member 138 has a magnetic repulsive force with the first magnet member 132 to be inserted. Thus, the first magnet member 132 is linearly reciprocated within the side magnet member 138. Of course, the side magnet member 138 can be deformed into various shapes and can be manufactured integrally with the second magnet member 134. [

The reference numerals not described are replaced with those described above.

The buffer 130 includes a first magnet member 132, a second magnet member 134, a sleeve 136, and a spring member 140.

Here, the first magnet member 132, the second magnet member 134, and the sleeve 136 are replaced with those described above.

At this time, the first magnet member 132 and the second magnet member 134 are buffered by the repulsive force in a state where they are spaced apart from each other, the buffer response speed may be lowered, and the buffer force is significantly lowered when the repulsive force range is exceeded.

As a result, the buffering force of the second frame 120 with respect to the first frame 110 can be compensated.

Thus, the spring member 140 elastically supports the second frame 120 relative to the first frame 110 in a complementary manner.

The spring member 140 is a coil spring made of a non-metallic material, and is provided inside the sleeve 136. One end of the spring member 140 is resiliently supported by the engagement protrusion 139 of the second frame 120 and the other end of the spring member 140 is resiliently supported at the end of the first frame 110 corresponding to the inner bottom surface of the sleeve 136, do. In addition, the spring member 140 is prevented from laterally bending by inserting the first magnet member 132 and the second magnet member 134 therein.

The reference numerals not described are replaced with those described above.
