[Industrial application field]

This invention relates to a bicycle stand. Relates to those provided at the grounding part of. Bicycles such as so-called practical bicycles and minicycles have their rear wheels lifted off the ground. It is equipped with a bicycle stand that can be kept stationary in a suspended state. This bicycle stand is the left side that is fixed to the back fork end of the bicycle frame. Place the stand legs, which are almost U-shaped when viewed from the rear, in an approximately upright position against the right pair of brackets. It is roughly configured by rotatably supporting the area from 1 to 3. has been done. A tension coil spring is installed between the stand legs and the above bracket. , when the stand legs are in the upright position, This state is held stably by the tension of the spring, while the stand legs are When rotated backward, the axis of the above spring crosses the support axis of the stand leg. , the stand legs are automatically moved to a nearly horizontal flip-up position by the tension of the spring. It is now possible to run it.

0002 By the way, the above stand legs have conventionally been formed by simply bending metal bars. As a result, the following problems were pointed out. In other words, the stand legs are made of bent metal bars, so this stand The contact area between the stand legs and the ground is extremely small, and there is no slippage on the metal surface. Since there is usually no means of stopping, the grounding part of the stand legs The frictional force between the ground and the ground is not sufficient, resulting in operational or functional issues. There are problems like. In other words, the stand legs that have been flipped up backwards can be rotated to an upright position while automatically Let's stabilize the bicycle by supporting the rear weight of the bicycle on these stand legs. When doing so, first contact the ground surface of the stand legs with the ground, and while maintaining this state, It is necessary to pull the bicycle back, but at this time, the stand legs are not in contact with the ground. Slippage occurs between the surface and the ground, making it difficult to position the bicycle as described above. There may be cases where

0003 You can also ride the bicycle with the stand legs upright as shown above and the wheels floating. Even if the positioning operation is successful, if the ground is sloped, do not stand upright. The stand legs may stand up due to insufficient friction between the ground contact part of the stand legs and the ground. There is also the problem that the entire bicycle may shift when the bicycle is in a tilted position. above If you simply want to solve the problem of insufficient friction between the stand legs and the ground, then For example, you can wrap rubber around the ground contact part of the stand legs mentioned above. However, even if such rubber is wrapped, it will not be possible to wrap it using insert molding, for example. The equipment and operations required for this purpose are complicated, leading to a significant increase in costs. The situation is such that it is not easy to recruit.

0004 In addition, only the left and right corners near the ground contact area of the stand legs, for example, can be fitted with an inset type. It is also possible to attach rubber to prevent friction, but if the left and right parts are separated like this, If two pieces of anti-friction rubber are fitted, the anti-friction rubber will fit into the stand legs. Due to the lack of adhesion force, it is difficult to secure the bicycle using the stand legs or to jump the stand. If this type of fitted rubber easily comes off as you repeatedly lift it up, This problem may arise.

[0005] The present invention was devised under the above-mentioned circumstances, and it We are working on the anti-slip material that is installed to increase the friction between the base and the ground. It can be easily attached to the stand legs, and the installation is more reliable. The task is to raise the level.

[0006]

[Means to solve the problem]

In order to solve the above problems, the present invention takes the following technical measures. In other words, the present invention provides a pair of back fork ends that support the rear wheels. For the pair of left and right brackets that are fixed, the pair of left and right leg shafts and this The stand is approximately U-shaped when viewed from the rear and has a horizontal grounding shaft that connects the lower ends of the leg shafts. The hand legs are rotatably supported at the upper ends of the pair of left and right leg shafts. In the bicycle stand, From the lower end of each of the above leg shafts to the above ground horizontal shaft A pair of left and right corner fitting parts that cover the front and rear sides of the insulator, and each corner fitting part along the lower surface of the grounding horizontal shaft part. A non-slip member integrally formed with the middle part connecting the frame fitting part is attached to the stand leg. It is characterized by being fitted and attached to.

[0007]

[Functions and effects of the idea]

The corner fitting part of the It has a connected structure.

[0008] Each corner fitting part is located on the outer surface of the lower end of the leg shaft, and below the ground contact horizontal shaft. It is configured to cover the surface or the front and back sides, and each of these corner fittings is When fitted into the stand leg, it is connected by the intermediate portion. death Therefore, the intermediate portion allows the left and right corner fitting portions to be drawn toward each other. from the outside to the inside of the corner fitting part between the leg shaft part or the ground contact horizontal shaft part. A full fitting force can be applied to each corner. Therefore, the invention for bicycles The anti-slip member on the stand is fitted into the stand legs from below. While it can be attached to the stand legs with simple operation, its attachment strength is However, it can easily come off due to the pulling action of the left and right corners by the intermediate part. It can be made sufficient without.

[0009] The anti-slip member is made of, for example, synthetic rubber or synthetic resin. The bottom surface of each corner can be provided with unevenness to prevent slipping. Can also be done. Therefore, the invention of the present invention, which is equipped with such a non-slip member, According to the stand for bicycles, it is difficult to set up the stand and keep the bicycle stationary. However, the above work is sufficient to prevent the ground contact part of the leg shaft from sliding on the ground. This can be done easily without any difficulty, and even if the road surface is sloped when it is in a stationary state, Even if the bicycle is placed in a stationary position, the entire bicycle may shift inadvertently. It will be resolved.

0010 As mentioned above, the anti-slip member is attached to the stand leg with sufficient mating force. Because it is attached to the stand, it is not possible to stand the stand legs or flip it up If the above-mentioned anti-slip member accidentally comes off and jumps even after repeated operations, problems are also avoided.
