Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bicycle which is mounted on a back hawk and a hub shaft of a frame, maintains an upright state when the vehicle is stopped, and flips the legs during traveling to maintain a substantially horizontal position. The present invention relates to a stand and a method of mounting the stand.

[0002]

2. Description of the Related Art As shown in FIG. 13, a conventional bicycle stand having a single leg is pivotally attached to a mounting member 1 for mounting an upper portion of a leg portion 7 to a back hawk 3 of a frame.
The operation member 12 is axially fixed to the leg portion 7, the spring 13 is suspended and attached to the operation member 12 and the mounting member 1, and the operation member 12 is pivoted against the elastic force of the spring to provide the operation member 12 above the operation member 12. The stopper or edge has a structure that allows engagement and release of the mounting member 1 to allow the legs to stand or flip up. The rear surface of the upper portion of the mounting member 1 is located outside the back hawk 3. And a hub nut 6 is fixedly mounted on the hub shaft 9 mounted on the back hawk 3 via the washer 5.

In a conventional bicycle stand having two legs, one leg has the same structure as that of the one leg stand, and the other leg has a mounting member 1 and a leg 7 as an axis. Then, the spring 13 is suspended and attached to the mounting member 1 and the leg portion 7, and the lower ends of the two leg portions are connected to form a "U" shape. This stand also has two mounting members. 1 is brought into contact with the outside of the back hawk 3, and is fixedly attached to the hub shaft 9 mounted on the back hawk 3 to the outside of the back hawk 3 with the hub nut 6 via the washer 5.

In the conventional one-legged and two-legged stand described above, a claw is provided in the back direction at the upper edge and the middle of the side edge of the mounting member 1, and the back hawk 3 is sandwiched between the claws above and below. There is something.

[0005]

In the above-mentioned conventional stand, the vibration of the rotation of the leg portion 7 is directly transmitted to the hub nut 6, and the hub nut 6 is loosened by the repeated rotation, so that the stand is not fixed and the wheel is not fixed to the wheel. As a result, the wheel rattles and the safety during traveling is adversely affected.
In the conventional mounting member 1 provided with upper and lower claws, the width of the back hawk 3 varies depending on the manufacturer's product, so a gap may occur between the upper and lower claws and the upper and lower edges of the back hawk 3. Yes, in that case the upper and lower claws do not function,
After all, the vibration caused by the rotation of the leg directly affects the hub nut 6.

In the conventional stand, the hub nut 6 is loosened by the vibration due to the rotation of the leg portion 7 as described above, and when the leg portion 7 is rotated, the mounting member 1 is also swung, so that the mounting member 1 is a back hawk. There is a possibility that not only the appearance will be unsightly, but also the back hawk 3 will be easily corroded by rust, by rubbing the surface of 3 to remove the paint.

[0007] In a stand with one leg, when standing up, the gravity of the bicycle causes a pressure to bend the mounting member 1 to the outside, but the pressure is supported only by the hub nut 6 and the washer 5, and the area is small. Therefore, there is a drawback that the mounting member 1 is easily bent around the hub nut 6 and the washer 5, and when the mounting member 1 is bent, the bicycle is likely to fall when the stand is erected.

In the conventional stand, when mounting and replacing the back hawk 3, it is troublesome to remove the hub nut 6 from the hub shaft 9 and mount the mounting member 1 and then tighten the hub nut 6.

The present invention can be applied to any manufacturer made back hawk 3 having different widths, or a back hawk 33 having a reverse claw 34 and an inclined bay entry portion 35, in which the bay entry portion 35 has a different inclination angle. A stand that can be fitted and that prevents the hub nut 6 from loosening and the mounting member 1 from bending due to the rotation of the legs 7, or prevents the hub nut 6 from loosening and bending the mounting member 1 and removes the hub nut 6 from the hub shaft 9. An object of the present invention is to provide a stand that can be easily attached to the back hawk 3 without removing the hub shaft from the back hawk, and a method for mounting the stand.

[0010]

According to the stand of the present invention, the mounting member is placed inside the back hawk, that is, the front surface of the mounting member is brought into contact with the inner surface of the back hawk, and the lower edge of the back hawk is the upper surface of the stepped portion or the shelf portion of the mounting member. Since the hub nut can be screwed to the outside of the back hawk without contacting the hub nut with the mounting member, the vibration of the leg rotation is not directly transmitted to the hub nut when it is attached to the back hawk, and the hub nut does not loosen. Prevent.

Further, particularly in a one-legged stand, the weight of the bicycle is applied to the attachment member when the legs are erected, and in the conventional stand, the weight acts to separate the attachment member from the back hawk. Since the washer and the hub nut that are attached to the outside of the back hawk and support the attaching member member are only the washer and the hub nut, there is a drawback that the attaching member is easily bent around the hub nut and the washer as described above. At times, the mounting member is in contact with the inside of the back hawk, and the back hawk supports the mounting member against the above-mentioned heavy pressure, and the lower edge of the back hawk is supported by the step portion, the shelf portion, or the protruding portion of the mounting member. Moreover, there is an effect that the mounting member is hard to bend.

The stand using the mounting member provided with the notch has the above-mentioned effect at the time of mounting, and in addition, the hub shaft can be removed from the back hawk even after the rear wheel is already mounted on the back hawk. Instead, simply loosen the hub nut to push the mounting member, insert the hub shaft into the notch through the notch opening, and tighten the hub nut to mount the mounting member. A conformable, mounted hub shaft and step, ledge, or ridge strongly pinch the lower fork of the back hawk to strengthen the attachment of the attachment member to the back hawk and hub shaft, and thus the stand.
