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.

In addition to a main stand provided in the center of a two-wheeled vehicle such as a motorcycle, side stands are provided on the sides of the vehicle, which 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 will take longer to turn than when the vehicle is tilted forward when parked. It turns out you can't do it.

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, as mentioned above, when the stand rotated backwards, the vehicle body lifted up, causing loss of maneuverability and the risk of a 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 pivotally mounted at its upper end by a shaft 3, so that its front portion abuts against the protrusion 1a of the stand bracket 1 in the parked state.

The stand 2 is pivotally attached to the stand bracket 1 by providing an elongated hole 4 extending slightly upward, and inserting a shaft 3 fixed to the upper end of the stand 2 into the elongated hole 4.

Note that the elongated hole 4 is not limited to this embodiment, and may be provided horizontally.

FIG. 1 shows the vehicle when it is parked; the left side of the figure is the front part of the vehicle body, the stand 2 is slightly tilted forward, and its lower end is in contact with the road surface 5.

A return spring 8 is stretched between a pin 6 set up on the stand bracket and a pin 7 set up approximately in the center of the stand 2.

A pin 9 is further installed in the front part of the stand bracket 1, and between this pin 9 and the aforementioned shaft 3, a shaft 3 is inserted.
A spring 10 is tensioned to pull forward.

The strength of the spring 10 is set so that the force of the return spring 8 is greater than the force with which the shaft 3 is pressed against the rear end of the elongated hole 4.

Next, the function of this side stand will be explained. In order to change from the running state shown in FIG. 3 to the parking state shown in FIG. 1, the driver applies a pushing force Fl to the stand 2 with his/her foot.

As a result, this force F1 and the vehicle weight F2 in a direction substantially perpendicular to this force F1 are applied to the stand 2.

As a result, the stand 2 is pressed against the protrusion 1a of the stand bracket 1, and the shaft 3 moves backward in the elongated hole 4 against the tension of the spring 10 and stops at the rear end, as shown in FIG. become a state.

Even if the force F1 is removed to park the vehicle, this posture will be maintained due to the action of gravity F2.

Next, when the vehicle body is raised to start running, the spring 10 moves the shaft 3 forward against the tension of the return spring 8, resulting in the state shown in FIG.

In this case, the relative positions of the elongated hole 4 and the protrusion 1a are set so that the center line 11 of the return spring 8 is located slightly forward of the center line 12 of the shaft 3.

As a result, the stand 2 will maintain this state.

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, the stand 2 will be in the state shown in Figure 2, and the road surface will be The impact is small, and it can be flipped up and retracted without impeding maneuverability.

Since the present invention is configured as described above, although it has a simple structure, it has the effect of eliminating the danger when driving without raising the stand.

Claims (2)

[Scope of utility model registration request] (1) In a side stand for a two-wheeled vehicle, in which an arm-shaped actuator is pivotally attached to a stand bracket attached to the vehicle body, and a return spring is stretched between the stand and the stand bracket, the stand is pivotably attached to the stand bracket. This is done by providing a long hole in the stand bracket horizontally or in an approximately horizontal direction, fixing a shaft to the upper end of the stand, inserting the shaft through the long hole, and connecting the shaft and the stand bracket. A spring was placed between the holes in a direction that pulled the shaft forward, and the strength of the spring was set so that the strength of the spring was greater than the force of the return spring pressing the shaft against the rear end of the elongated hole. A side stand for two-wheeled vehicles. (2) A side stand for a two-wheeled vehicle according to claim 1, wherein the elongated hole provided in the stand bracket is oriented slightly rearwardly upward relative to the vehicle body.
