Description

[Detailed Description of the Invention] The present invention relates to a side stand for a two-wheeled vehicle such as a motorcycle, and is designed to prevent danger even when the user forgets to raise the stand while driving.

A two-wheeled vehicle such as a motorcycle has a main stand provided in the center thereof, as well as a side stand provided on the side thereof that can be easily operated.

The general structure of this side stand is that an arm-shaped stand is pivotally supported on a stand bracket attached to the vehicle body, and a return spring is stretched between the stand and the stand bracket.

In this side stand, when the stand is parked, the stand is tilted slightly forward from a state perpendicular to the road surface, so that the stand does not naturally rise due to the weight of the two-wheeled vehicle.

Therefore, when this stand is rotated around the pivot point of the stand bracket, when the stand is perpendicular to the road surface, it cannot be rotated without raising the vehicle compared to when it is tilted forward when parked. It turns out.

Therefore, when raising the stand, the driver must hold the handle of the two-wheeled vehicle and raise it slightly to the side opposite to the side to which the stand is pivoted.

In this way, you can raise the stand and drive, but if you forget to raise the stand and drive, the tip (lower end) of the stand will come into contact with the road surface, which is dangerous. When the vehicle was about to stand up, the lift of the vehicle body when the stand rotated backwards, as described above, could disrupt maneuverability and cause the vehicle to fall.

The present invention has been made in view of this point.

One embodiment of the present invention will be explained with reference to FIG. 1. 1 is a stand bracket, and a vehicle body (frame not shown)
It is a plate-shaped thing attached to the bottom of the.

This stand bracket 1 includes an arm-shaped stand 2.
is pivoted by a shaft 3 at its upper end.

This figure shows the vehicle when it is parked.The left side of the figure is the front of the vehicle, the stand 2 is slightly tilted forward, and its lower end is on the road surface.
is in contact with

A return spring 7 is stretched between a pin 5 set up on the stand bracket 1 and a pin 6 set up approximately in the center of the stand 2.

At the front part of the stand 2 of the stand bracket 1, a lever 8 having a shape slightly bent at the center of the lever is pivotally mounted at the bent part by a shaft 9.

When this lever 8 is rotated, its lower end is connected to the stand 2.
An elastic member 11 made of a compression spring is interposed between the protrusion 10 of the stand bracket 1 and the upper end of the lever 8.

The stand bracket 1 is provided with a stopper 12 with a bent pin and a stopper 13 with the stand bracket 1 bent. 1) to a state substantially perpendicular to the road surface (the state shown in FIG. 2), and is regulated so as to be in contact with the front part of the stand 2.

Note that the position of the stopper 12 is determined by the position of the stand 2 as described above.
is designed to push the stand 2 to a position almost perpendicular to the road surface, but at this time the center line 14 of the return spring 7 is set to be located slightly forward of the center line 15 of the shaft 3. (See Figure 2).

Next, the function of this side stand will be explained. In order to change from the driving state shown in FIG. 3 to the parking state shown in FIG. 1, the driver presses the stand 2 with his foot.

This will add a certain amount of pressure.

As a result, the stand 2 receives this force F1 and the vehicle weight F2, which is almost orthogonal to the force F1.

Then, due to the force Fxt, the stand 2 rotates the lever 8 clockwise against the elasticity of the elastic member 11, and the posture shown in FIG. 1 is obtained.

At this time, the lower end of the lever 8 is in contact with the stopper 13.

After that, even if the force F1 is removed, the no-turn spring 7 urges the stand 2 clockwise (forward), so the stand 2 will not rotate backward (counterclockwise) due to its own weight F2.

Next, when the vehicle body is raised to start driving, the stand 2 is pushed rearward via the lever 8 by the force of the elastic member 11, resulting in the state shown in FIG.

In this case, as described above, since the center line 14 of the not-turn spring 7 is located slightly forward of the center line 15 of the shaft 3, the stand 2 will maintain this state unless an external force is applied to the stand 2.

Raise the vehicle and move stand 2 backwards with your foot (right side of the diagram)
If you kick it up and put it in the state shown in Figure 3 (stored state), you can drive, but if the driver forgets this and drives, stand 2 will be in the state shown in Figure 2. Even when the stand is parked, the impact from the road is smaller compared to a conventional stand that leans forward, and the stand can be flipped up and stowed without impeding maneuverability.

Since the present invention is constructed as described above, it has a simple structure with a few additional parts added to the conventional side stand.
This has the effect of eliminating the danger of driving while forgetting to raise the stand.
