Description

[Detailed Description of the Invention] The present invention relates to a removable side stand suitable for a motorcycle, particularly a competition motorcycle. Competition motorcycles generally do not even have a side stand on the body to avoid stiffness and to reduce weight. Therefore, a removable side stand is required to keep the vehicle upright when parking.

The present applicant has developed a side stand of this type that has a crotch part formed at the upper part to receive a protrusion on the side of the vehicle body, a leg part of a predetermined length that is in contact with the ground at the lower part, and which supports the vehicle body on the left or right side in the direction of travel. The first proposal was to support a structure tilted to
(see publication).

The side stand proposed above is lightweight, has a simple structure, and is easy to attach and detach from the vehicle body, but because it is configured to support the side of the vehicle between the front and rear wheels, it is difficult to park using the side stand. When you ride a car in a state where the front and rear wheels are supported by suspension, the car body moves up and down, and the angle of inclination of the car body changes accordingly.

In view of the above problems, it is an object of the present invention to provide a removable side stand that is stable and has very little change in the angle of inclination of the vehicle body due to the movement of the suspension even when the vehicle is ridden with the removable side stand in use.

In order to achieve the above object, the present invention provides a locking part 1 on the top of the side stand body 1 that is fitted onto and removed from one end of the rear wheel shaft of a motorcycle in the axial direction.
a, and a ground contact portion 1b having a predetermined length extending in the longitudinal direction of the vehicle body is provided at the lower part of the main body 1.

FIG. 1 shows an embodiment of the removable side stand of the present invention made using a steel bar material, in which a steel bar material 2 is bent into a substantially isosceles triangle so that both ends thereof become apexes 2a. A short bar piece 3 is fixed to the apex 2a of the triangular frame by welding or the like in a direction intersecting the triangular surface to form a locking part 1a, and the base of the triangular frame is used as a grounding part 1b.

In Fig. 2, a short rod piece 5 is fixed to the top of a substantially isosceles triangular plate 4 by welding or the like in the direction intersecting the plate 4 to form a locking part 1a, and the bottom side of the plate 4 is a grounding part 1b. be. In the figure, 6 is a hole punched in the center of the triangular plate 4 to make it lighter.

The shape of the side stand main body 1 is different from the triangular shape in the embodiments shown in FIGS. 1 and 2, for example, an inverted T shape.
The shape of the characters is arbitrary. The height of the main body 1 is made slightly lower than the radius of the wheel.

Note that the locking portion 1a in the above embodiment uses rod pieces 3 and 5 so that it can be inserted and locked at the end of the hollow rear wheel axle in order to reduce the weight of the vehicle.
If a is formed into a cap shape and is placed over the end of the rear wheel axle, it can be locked regardless of the configuration of the wheel.

To attach the removable side stand of the present invention to a motorcycle, as shown in FIGS. 3 and 4, with the vehicle body 7 upright, attach the locking part 1a of the removable side stand 1 to one end of the rear wheel axle 8. The stand 1 is fitted and locked in the axial direction, and the vehicle body 7 is tilted until the ground contact portion 1b of the stand 1 touches the ground E.
touches the ground beside the vehicle body 7, receives the load of the vehicle body 7, and supports the vehicle body 7.

To remove the detachable side stand 1 from the vehicle body 7, the vehicle body 7 is raised vertically, the ground contact portion 1b is lifted off the ground E, and the locking portion 1a is pulled out from the rear wheel axle 8 in the axial direction.

In the figure, 9 is the swing arm, 10 is the front wheel, 11
12 is a rear wheel, 12 is a front suspension, 13 is a rear suspension, 14 is an engine, 15 is a body frame, and 16 is a seat.

As described above, the removable side stand of the present invention supports the vehicle body 7 by engaging the upper locking portion 1a with the end of the rear wheel axle 8, so that it is possible to ride the vehicle with the side stand 1 attached to the vehicle body 7. In this case, the vehicle body 7 moves up and down by the front and rear suspensions 12 and 13, but the locking angle of the vehicle body 7 does not change, so stability is good.

Since the side stand 1 is locked using the rear wheel shaft 8, there is no need to separately provide a member for locking the detachable side stand 1 to the vehicle body 7, which is effective in reducing the weight of the vehicle body.

The locking portion 1a of the side stand 1 on the end of the rear wheel axle 8 is configured to be removed in the axial direction, so that the locking state can be firmly maintained, and the vehicle body 7 can be stood vertically. Therefore, the side stand 1 can be quickly and easily attached to and detached from the vehicle body 7.

In addition, the ground contact portion 1b of the side stand 1 is connected to the vehicle body 7.
Since it has a predetermined length extending in the front-rear direction, it has the effect of reliably restraining the movement of the vehicle body 7 in the front-rear direction.
