Description

The present invention relates to a two-wheeled vehicle self-supporting holding device, and more particularly, to a two-wheeled vehicle self-supporting holding device that eliminates an unstable state when the two-wheeled vehicle is at a low speed, stops, and starts and holds the two-wheeled vehicle independently .

Two-wheeled vehicles such as bicycles and motorcycles may be unstable and fall down at low speeds before stopping, when waiting for traffic lights, etc., and when starting off, and must be supported with a foot while stopping. A large force is required to support the combined weight of the two-wheeled vehicle (load caused by tilting), and there are many safety issues.

In order to solve such problems, when the motorcycle is stopped, by operating the handle portion while in the riding position, the motorcycle is operated so as to ground the stand to the ground, so that the vehicle can be maintained in an independent state. In order to support the large force that combines the weight of the driver with the weight of the motorcycle by remotely controlling the operation of the stand at the handle portion, the stand device for interlocking the handle portion with the stand is proposed. Various interlocking mechanisms are required, and there is a problem that it is difficult to respond to changes in response to changes in the road surface.

The second pivot shaft 11 is rotated about the second pivot shaft 11, and the rear end portion of the stand 9 is grounded so that the two-wheeled vehicle can be prevented from falling down.

In general, the height of the saddle of a two-wheeled vehicle, particularly a bicycle, should be set so that the driver's knees are slightly bent when the pedal comes to the lowest point, especially when considering exercise efficiency. Most drivers have the saddle at this height, which is a position where the driver's feet do not reach the ground when stopped, and is extremely unstable.

For this reason, many ordinary drivers who repeatedly stop and start in urban areas are able to lower the saddle position so that they can touch the ground when stopping and starting. You are forced to drive in an easy-to-use state.

According to the two-wheeled vehicle self-supporting holding device, such a problem can be solved, and in particular, the configuration in which the front portion of the saddle is supported so as to tilt downward and the saddle is supported so as to be movable forward and downward. If the front part of the saddle is tilted downward and the saddle is moved forward and downward, the position where the driver sits is lowered and the driver can easily touch the ground. In addition to grounding the stand, if necessary, the driver can also ground to keep the motorcycle more stable and ensure safety.
