Description

Holding Stand for Bicycle Using Plural Roller

The present invention relates to a bicycle mounting stand using a plurality of rollers, and more particularly, to mount a bicycle without a side stand, and to exercise using a bicycle without a separate cycle exercise device indoors, The present invention relates to a bicycle mounting stand using a plurality of rollers that can facilitate the wheels for maintenance and cleaning.

A general bicycle may be easily mounted on the ground when the bicycle is not equipped with a cradle installed to be folded in the main body. However, since extreme sports (mountain sports) or mountain bikes are used in mountain roads with a lot of obstacles, there is no collapsing cradle because there is a risk of collision with the surrounding obstacles.

In this case, when the bicycle is to be stored, the bicycle must be leaned against the wall, or the bicycle must be stored with a separate mounting stand.

However, since the conventional mounting stand is fixed in size, it may not be inserted in the mounting stand or loosely fixed when mounted due to various sizes of bicycles, sizes of bicycle wheels and widths of bicycle wheels according to the driver's body shape, and the like. There is a problem.

In addition, for the chain and rim cleaning, there is a problem in that the chain and rim cleaning of the bicycle should be performed by holding or separating the front and rear wheels from the cradle to the ground.

At this time, the first central axis 410 to the third central axis 430 may be made of a hinge.

The first roller 310, the second roller 320 and the auxiliary roller 330 described above are all different only in the coupling position, the shape is all made of the same configuration. The first roller 310, the second roller 320, and the auxiliary roller 330 are driven by the rollers 310, 320, 330 and the bicycle wheels 510, 520 in contact with the bicycle wheels 510, 520. It consists of a support plate formed to extend in the left and right ends of the roller portion to prevent the departure.

Next, the first roller 310, the second roller 320, and the third roller 330 will be described at a time by dividing the respective embodiments.

Roller according to the first embodiment

4 is a front view of the roller according to the first embodiment of the present invention. As shown in FIG. 4, the first roller 310, the second roller 320, and the auxiliary roller 330 according to the first embodiment may contact the roller wheels 510 and 520. The outer circumferential surface of the 330 is made of a curved surface to correspond to the bicycle wheels (510, 520). As such, when the outer circumferential surfaces of the rollers 310, 320, 330 are curved, the center of the width of the bicycle wheels 510, 520 is automatically coupled to the center of the rollers 310, 320, 330 along the curved surface. By reducing the vibration of the bicycle wheels (510, 520), the rotation is facilitated, and can be stably coupled to the bicycle mounting stand (10).

Roller according to the second embodiment

5 is a cross-sectional view of the roller according to the second embodiment of the present invention. The first roller 310, the second roller 320 and the auxiliary roller 330 according to the second embodiment of the bicycle wheel (510, 520) because the size of the bicycle also varies depending on the user's physique, etc. The widths of the first roller 310, the second roller 320 and the auxiliary roller 330 may be varied to correspond to the widths of the 510 and 520. At this time, the first roller 310, the second roller 320 and the auxiliary roller 330, as shown in Figure 5, the first member 350 which is symmetrical with each other by longitudinally terminating one side of the center of the width and It is divided into the second member 360. In this case, an insertion groove 351 is formed at one side of the split surface center of the first member 350, and an insertion protrusion 361 corresponding to the insertion groove 351 is protruded at one side of the split surface center of the second member 360. Is formed.

Threads are formed in the inner circumferential surface of the insertion groove 351 and the outer circumferential surface of the insertion protrusion 361 along the longitudinal direction. As a result, the first member 350 and the second member 360 may be fastened and separated along the threads formed in the insertion grooves 351 and the insertion protrusions 361. 310, the widths of the second roller 320 and the auxiliary roller 330 may be varied. That is, when the insertion groove 351 and the insertion protrusion 361 are rotated to the maximum to combine the first member 350 and the second member 360, the first roller 310, the second roller 320 and the auxiliary roller The width of 330 is minimum. In addition, the first member 350 and the second member 360 may be varied so that the widths of the first roller 310, the second roller 320, and the auxiliary roller 330 gradually become wider while being released along the thread. .

Roller according to the third embodiment

6 is a cross-sectional view of the roller according to the third embodiment of the present invention. The first roller 310, the second roller 320, and the auxiliary roller 330 according to the third embodiment of the present invention are divided into the first member 350 and the second member 360 like the second embodiment. The insertion grooves 351 and the insertion protrusions 361 are formed, respectively.

At this time, the inner peripheral surface of the insertion groove 351, as shown in Figure 6, by adjusting the locking position of the insertion protrusion 361 of the second member 360 of the auxiliary rollers 330 to the first roller 310 A plurality of fixing grooves 352 are formed along the insertion direction of the insertion protrusion 361 to adjust the width. The fixing groove 352 may be provided in plural on one virtual straight line on one side of the inner circumferential surface of the insertion groove 351, or may be provided in plural on the plurality of virtual straight lines along the inner circumferential surface of the insertion groove 351.

One end portion of the outer circumferential surface of the insertion protrusion 361 is inserted into the insertion groove 351 to fix the first member 350 and the second member 360, but when a force higher than a reference pressure is applied, the insertion groove 351 The fixing protrusion 362 may be separated to change the fixing position so that the widths of the first roller 310, the second roller 320, and the auxiliary roller 330 may be varied. The fixing protrusion 362 is composed of a fixed ball 365, an elastic member 364 and the fixed ball receiving portion 363.

The fixed ball receiving portion 363 is formed at a position corresponding to one side of the outer circumferential end of the insertion protrusion 361, preferably the fixing groove 352 provided on the innermost side of the fixing groove 352 of the insertion groove 351. To accommodate the fixed ball 365 and the elastic member 364.

The elastic member 364 is a device inserted into the fixed ball receiving part 363 to elastically support the fixed ball 365 in the direction of the fixing groove 352 of the first member 350. The elastic member 364 may be any type as long as it can elastically support the fixing ball 365 in the fixing groove 352 direction, but it is preferable to use a coil spring.

When the fixed ball 365 is supported by the elastic force of the elastic member 364 and moves to a position coinciding with the fixing groove 352, the fixing ball 365 is inserted into the fixing groove 352 to be the first member 350 and the second member 360. It is a device for fixing.

That is, the fixing ball 365 of the fixing protrusion 362 is inserted into the fixing groove 352 to fix the first member 350 and the second member 360, and the first member 350 and the second member ( When the pulling force 360 or the pressing force is greater than the elastic force of the elastic member 364, the fixing ball 365 is separated from the fixing groove 352 to change the position of the auxiliary rollers 330 to the first roller. The width of 310 is varied.

Roller according to the fourth embodiment
