Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a side stand for a two-wheeled vehicle, in which the side stand is automatically retracted when the vehicle is raised to start, and even when parked on a downhill slope, depending on the weight of the vehicle. This prevents the side stand from rotating to ensure safety, and when the side stand is pulled out to a predetermined angle, the detent works from that position, improving usability.

In addition to a main stand that supports the rear wheel by raising it above the road surface, a two-wheeled vehicle is provided with a side stand that allows the two-wheeled vehicle to be parked at a slight incline for convenient parking. This side stand has the upper end of an arm-shaped stand pivoted to a stand bracket attached to the vehicle body, and a spring is tensioned between approximately the center of the stand and the stand bracket, allowing the stand to be raised rearward for driving. The stand is kept in the raised position when the machine is opened.

With conventional models, when the vehicle is stopped using the side stand, the spring applies force to the stand in the opposite direction to the direction in which it is stored, so if you forget to raise the stand while driving,
This stand had the disadvantage that it came into contact with the road surface, creating a danger. Furthermore, when the side stand is used to park the vehicle on a downhill slope, when the two-wheeled vehicle starts moving forward due to the weight of the vehicle, there is a risk that the stand will be raised, causing the vehicle to fall.

The present invention aims to eliminate these drawbacks. One embodiment of the present invention will be described with reference to FIG. 1. Reference numeral 1 denotes a side stand, which includes a stand support 4 whose upper end is pivotally connected to a stand bracket 3 by a shaft 2, and a bent lower part of the stand support 4. The stand 6 is fitted into the hole 5 and supported by the stand support 4 so as to be movable in the longitudinal direction thereof. At the lower end of the stand 6, there is a stand show 6a.
is formed.

A pin 7 is installed at the rear end of the stand bracket 3, and this pin 7 and the stand support 4
A return spring 9 is stretched between the pin 8 and the pin 8 that is set up approximately in the center of the spring. As a result, when the side stand 1 is raised up, the return spring 9 applies a force in the counterclockwise direction in the figure.

One end of the connecting plate 0 is pivotally mounted above the stand support 4 by a shaft 11. The other end of the connecting plate 10 is pivotally attached to the upper end of the stand 6 by a shaft 12 provided at the upper end of the stand 6. As a result, the stand 6 is supported by the stand support 4 so as to be movable in its longitudinal direction. Reference numeral 13 denotes a spring, which is hung between a pin 14 set up approximately at the center of the connecting plate 10 and a pin 15 set up slightly below pin 8 of the stand support 4. 10 hits the stopper 16 provided on the stand support 4,
A force is given to the side stand 1 to move it downward in the figure.

At the bottom of stand bracket 3 is stand 6.
the step part 17 that receives the upper end of the stand support 4;
A step portion 18 is formed to receive the holder in an upright state. When the stand 6 is raised relative to the stand support 4 by parking the motorcycle, the stepped portion 17 receives and engages the shaft 12 at the upper end of the stand 6 as shown by the broken line in the figure, and the side stand 1 The stepped portion 18 prevents the stand support 4 from rotating counterclockwise in the figure.
This restricts rotation in the clockwise direction in the figure after the upright state (the state shown by the broken line).

19 is a plate whose upper end is fixed to the stand bracket 3. The lower part of this plate 19 has one surface as a cam surface 20a,
A guide plate 20 having a valley portion 20b is attached to the top of the cam surface 20a.

An arm-shaped check plate 21 is pivotally mounted approximately at the center of the plate 19 by a shaft 22. As shown in FIG. In the free state, this check plate 21 is in contact with the upper end of the guide plate 20 as shown in the figure due to its own weight, but this is because a coil spring 23 is provided as shown in FIG. plate 2
1 may be given a rotational force in the clockwise direction in FIG.

This side stand configured in this way 1
In order to park a motorcycle, when the side stand 1 is raised as shown by the broken line in FIG. rise to a certain point. As a result, the connecting plate 10 rotates clockwise about the shaft 11 and stops when the shaft 12 at the upper end of the stand 6 contacts the stepped portion 17 (or at a position immediately before contact). In this state, even if you try to start the motorcycle, the shaft 12 of the stand 6 is engaged with the step 17, so the side stand 1 is moved in the storage direction (counterclockwise direction).
It does not rotate.

The above is the basic operation at the time of parking in this embodiment, but the present invention further operates as follows. That is, when pulling out the side stand 1 to park the motorcycle, the shaft 12 moves along the cam surface 20a of the guide plate 20,
Eventually, the check plate 21 will be pushed up and the valley 2 will be removed.
0b. In this state,
Even if the driver takes his foot off the side stand 1, the side stand 1 will not return to the stowed state.

The general operation for a driver to raise the side stand is immediately after stopping the motorcycle, while still riding the motorcycle, pull out the side stand from the vehicle body with your feet, and then raise the side stand so that the lower end of the pulled out side stand is in contact with the road surface. We lean towards it. Therefore, the side stand is pressed down with the foot that is used to tilt the vehicle, creating the risk of the vehicle tipping over. In this regard, in the present invention, as described above, even if the driver takes his foot off the side stand 1, the side stand 1 does not return to the stowed state, so there is no risk of the vehicle falling over and the vehicle can be parked perfectly. When the vehicle body is tilted with the side stand 1 detented in this manner, the stand shoe 6a touches the road surface and raises the stand 6 relative to the stand support 4, so the shaft 12 pushes up the check plate 21 and rises. and step part 1
7.

Next, when the vehicle body is raised to start, the stand shoe 6a of the stand 6 is separated from the road surface, so the stand 6 is lowered by its own weight, and the connection plate 10 and the stepped portion 17 are disengaged.
As a result, the side stand 1 is no longer prevented from rotating, so it is automatically rotated counterclockwise by the return spring 9 and stored. Note that since the spring 13 acts in the direction of lowering the stand 6, this operation is ensured. When the vehicle body is raised to start, the shaft 12 disengages from the stepped portion 17 and descends, but the presence of the check plate 21 prevents it from falling back into the valley portion 20b.

As explained above, the device of the present invention is easy to use because the side stand automatically retracts when the vehicle is raised to start, and it also rotates depending on the weight of the vehicle when parked on a downhill slope. This has the advantage of significantly improving safety. When the side stand is pulled out to a predetermined angle, the detent works from that position, so there is no risk of it falling over, and the driver can operate it with peace of mind, significantly improving usability. In addition, in the above embodiment, it is possible to omit the connecting plate if the stand is properly held with respect to the stand support.
