Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a stand device for a motorcycle.

(Conventional Technique #I) In a motorcycle, in order to make the vehicle body independent on the ground when parking, a stand member is usually pivotally supported at the bottom of the vehicle body so as to be freely rotatable in the vertical direction. in this case.

The work for making the vehicle body independent on the ground is performed as follows.

That is, first, the stand member in the storage position that has been rotated upward is rotated downward, and its rotating end is once grounded.Next, it is rotated upward to lift the vehicle body around this grounding point. At this time, the vehicle body is supported on a stand member that stands up about the grounding point, thereby making the vehicle body independent.・ (Problem to be solved by the invention) By the way, since motorcycles are generally heavy, it takes a lot of effort to lift the body to make it stand on its own on the ground as described above. It is said that Therefore, this task is not easy.

(Objective of the Invention) The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to make it possible to easily carry out work for making a vehicle body independent on the ground with little effort.

(Structure of the Invention) A feature of the present invention for achieving the above object is that a stud member is pivotally supported in the lower part of the vehicle body so as to be freely rotatable in the downward direction, and a stud member is supported in the lower part of the vehicle body as to be freely rotatable in the vertical direction. The movable lever is pivotally supported, and a foot part is formed at the rotating end of the tread lever, and the longitudinal midway part of the tread lever and the rotating end side of the stand member are connected by a connecting rod. It is in.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

A is a motorcycle, and the body frame 2 of the vehicle body 1 is
An engine 3 is supported. Further, a front wheel 5 is supported at the front part of the body frame 2 via a front fork 4, and a rear wheel 8 is supported at the rear part of the body frame 2 via a rear arm 7. This rear wheel 8 is interlocked and connected to the engine 3. 9 is the fuel tank, l
O is a seat, and a footrest 12 is attached to the vehicle body frame 2 in correspondence with this seat lO.

A stand device 14 that allows the vehicle body 1 to stand on its own is provided at the rear lower portion of the vehicle body frame 2. This stand device 14 will be explained below.

This stand device 14 has a stand member 16, and this stand member 16 is pivotally supported by a bracket 18 protruding from the vehicle body frame 2 so as to be freely rotatable in the vertical direction. The stand member 16 includes a pair of left and right leg members 16a, 16a, each end of which is pivotally supported by a bracket 18, and these leg members 16.
Arch member 16b installed between each rotation end of a and 16a
It has

A spring 20 that selectively biases the stand member 16 either upward or downward is attached between the bracket 18 and the midway portion in the longitudinal direction of the leg member L6a.

Further, by rotating the stand member 16 upward, it can be placed in the storage position (as shown by the dashed line in FIG. 1).
A stopper (not shown) is provided to prevent the stand member 16 from rotating further from this position. on the other hand,
If the stand member 16 is rotated downward, the vehicle body l can be placed in a position where it is supported independently (as shown by the two-dot chain line in the figure), and the stand member 16 is prevented from rotating further from this position. A stopper (not shown) is provided.

Near the rear of the stand member 16, a pedal lever 22 is pivoted to the bracket 18 via a pivot shaft 23 so as to be freely rotatable in one downward direction. A foot section 24 is formed at the rotating end of the foot lever 22.

Further, a connecting rod 26 is installed between the midway in the longitudinal direction of the pedal lever 22 and the rotating end side of the leg member 16a. The upper end of this connecting rod 26 is pivotally supported by an upper pivot shaft 27 to the tread lever 22, and the lower end of the connecting rod 26 is pivotally supported to the leg member 16a by a lower pivot shaft 28.

(Function) Next, a procedure for making the vehicle body 1 self-supporting with the above configuration will be explained.

The dashed-dotted line in FIG. 1 shows a state in which the stand member 16 is rotated upward by the biasing force of the spring 20 and is in the storage position. From this state, when the foot part 24 is stepped on and the foot lever 22 is rotated downward, the stand member 16 is rotated downward via the connecting rod 26. Here, first, the first
The rotating end of the stand member 16 is brought into contact with the ground G as shown by the solid line in the figure.

Next, the vehicle body 1 is rotated upward about this grounding point, but in this case, weight is applied to the foot pedal 24 to rotate the pedal lever 22 downward. Then, the stand member 16 is rotated about the grounding point via the connecting rod 26, and the vehicle body 1 is supported on the stand member 16 so as to be independent (as shown by the two-dot chain line in FIG. 1).

(Effects of the Invention) According to the present invention, the tread lever is pivotally supported at the bottom of the vehicle body so as to be rotatable in the vertical direction so that the rotating end becomes the foot pedal, and the longitudinal midway part of the tread lever is connected to the stand. Since the rotation end side of the member is connected with a connecting rod, when the car body is made to stand on its own, when you put your weight on the foot pedal and rotate the pedal lever downward, the force increases according to the lever ratio of the pedal lever. The resulting rotational force acts on the stand member. Therefore, by using body weight, the vehicle body can be slightly rotated upward around the grounding point of the stand member, and this vehicle body can be supported on this stand member. Therefore, the work to make the vehicle body independent on the ground is possible. can be easily done with little effort.
