Description

[Detailed Description of the Invention] The present invention relates to an auxiliary standing device that allows the main stand of a motorcycle to be easily erected.

Motorcycles have a sub-stand that maintains the body when it is tilted and a main stand that holds the body in an upright position.The main stand has an inverted U-shape when viewed from the front. It is pivotally attached to the vehicle body at the top and is biased and retracted in the direction of collapse by a spring, so that it does not get in the way of driving. Lift it while moving it.

This operation of raising the main stand must be performed from one side of the vehicle body, which is difficult to operate and requires lifting the vehicle body, which is difficult work.
In particular, large motorcycles have a large body weight, which makes raising the main stand extremely difficult and requires a large amount of force. Therefore, a fixed foot pedal is attached to one of the legs of the main stand, and the pedal force is used to raise the main stand, but a sufficient effect of assisting in standing up cannot be expected.

The present inventor devised the present invention in order to solve the above-mentioned problems in raising the main stand of a motorcycle. This and the push-up arm, which is removably engaged with the vehicle body, are pivotally connected with a rod, and a lever-linked booster mechanism is constructed using pedals, rods, etc., aiming for a simple mechanism and reliable operation. To provide a main stand raising assist device for a motorcycle, which allows the main stand to be raised easily and easily.

Next, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Fig. 1 is a schematic side view of the rear part of a motorcycle; 1 is a frame formed of pipe material, etc.; the figure shows the middle rear lower part of the frame; the frame is arranged symmetrically on the left and right, and includes cross members (not shown), etc. are connected with. The figure shows an exhaust pipe 2 extending to the rear of the frame 1 and a rear wheel 3, and a bracket 4 is installed at a suitable position on the frame 1 in the figure, extending downward to the rear in the figure. The upper part of the main stand 5, which is shaped and wide at the end, is pivoted on a support shaft 6 so that it can be raised and lowered freely, and specifically, the left and right legs 5 of the main stand 5
A pipe member 5b connecting the upper ends of the pipe members a and 5a is fitted onto a support shaft 6 fixedly mounted on the bracket side, and is pivotably supported so as to be able to rise and fall.

A receiving piece 4b is integrally extended to one of the left and right brackets 4, for example, the left bracket 4a, and a link 7 forming a push-up arm is pivotally connected to the receiving piece 4b by a pin 7a. On the other hand, a bearing part 5c is fixedly installed on the leg of the main stand 5 in the same direction, and the base part of the operating pedal 8 is fitted and pivotally supported on the bearing part 5c. A base end portion 8c projects inside the leg through the bearing portion 5c, and a connecting piece 9 is integrally fixed to this.

The lower end of a rod 10 forming a push-up link is pivotally connected to the tip of the connecting piece 9 by a pin 10a, and the upper end of the rod 10 is pivotally connected to the free end of the link 7 by a pin 10b. The main stand is fixed and engaged in a guide hole 11 provided at the rear of a receiving piece 4b on the bracket side, which has a rectangular cross section as shown in FIG. 3 and has a cutout 11a facing downward. The pin 10b is connected to the other end of a return spring 12 whose one end is locked to the receiving piece 4b, and a regulating pin 13 is provided protruding from the inside of the leg piece provided with the above mechanism.

FIG. 1 shows a state in which the main stand 5 is retracted. From this state, the main stand 5 is swung diagonally downward, the tip is in contact with the ground, and the foot part 8a of the pedal 8 is
Step on it with your foot and push it down. As a result, the connecting piece 9 of the pedal 8 swings in the opposite direction using the bearing portion 5c as a fulcrum, which functions as a lever for the ratio between the fulcrum of the connecting piece and the pedal, and the link mechanism, that is, the rod 10 and the link 7, are pushed up. , this pushing up force is applied to the pin 10b connecting the link 7 and the rod 10 to the receiving piece 4b.
is transmitted to the inner edge of the guide hole 11, and the receiving piece 4b is lifted, that is, the frame 1 is lifted and moved upward and rearward. This state is shown in FIG.

Further depression of pedal 8, accompanied by rod 1
Frame 1 rises with the push-up swing of 0, and rod 1
When the pin 10b swings at 0, the pin 10b swings together, and the notch 11a of the guide hole 11 of the receiving piece 4b
, and when the stand 5 is in the upright position, the pin 10
b comes out of the guide hole 11 and becomes free, as shown in FIG. 4, and the link mechanism is disengaged from the frame side and becomes free. The swing limit of the link mechanism is regulated by a regulating pin 13 as shown in FIG.

The lever action and link mechanism allow the main stand 5 to stand up very easily, and in order to fold down and store the main stand from the state shown in Figure 4, lift the pedal 8 and move the vehicle forward to fold down the stand 5. The stand 5 falls down, the pin 10b of the rod 10 restrained by the pin 7a engages with the guide hole 11, and the state shifts from the state shown in FIG. 2 to the retracted state shown in FIG. 1.

FIG. 7 shows a modified embodiment in which a pandagraph type link mechanism is used, and the connecting piece 109 of the pedal 108 is pivotally mounted on the arm 105a of the stand 105.
is pivotally connected to one end of the link 110, the other end of the link 110 is pivotally connected to the intermediate link 114 pivotally connected to the intermediate part of the arm 105a, and the link 115 extending beyond this, and the free end of the link 115 is connected to the vehicle body. It is pivoted to the side support piece 104.

As is clear from the above, according to the present invention, it is possible to stand up a heavy motorcycle such as a large motorcycle with light weight and extremely easy using the feet, and mechanically it employs a lever and link mechanism. It has many advantages such as reliable operation and simple structure.
