Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a side stand for a motorcycle that has a full air ring that covers the front part of the vehicle body from above to the bottom or an under cowl (hereinafter collectively referred to as a cowling) that covers the lower part of the front part of the vehicle body.

A motorcycle cowling covers the vehicle body in a streamlined shape from the front to the sides, and not only improves aerodynamic performance while driving, but also guides air to the engine area to improve engine cooling. ,
It also has a design effect. Therefore, it is preferable that such a cowling extend as far back as possible along the side of the vehicle body.

On the other hand, motorcycles are usually provided with a side stand. The side stand is flipped up to a storage position along the side of the vehicle body when the vehicle is running, and rotates downward when the vehicle is stopped, protruding downward from the side of the vehicle body to support the vehicle body. The installation position of the side stand should be determined in relation to the center of gravity of the vehicle, that the driver can easily move the side stand to the extended position while straddling the vehicle, and that the side stand will not interfere with other vehicle body parts when raised to the retracted position. It must be determined by taking into consideration various conditions such as this, but in order to satisfy these conditions, it will inevitably be provided on the side of the lower front part of the vehicle body.

As mentioned above, this position is a good place to cover with a cowling to improve aerodynamic performance, but since the side stand must be able to protrude outward from the vehicle body for its function, it is not possible to cover this part with a cowling. I'm not going. Therefore, for motorcycles equipped with a side stand, the cowling must be cut off in front of the side stand position, or a notch must be provided in the cowling as a relief for the side stand. The effects and design effects had to be limited. Also, if the effect of the cowling was particularly important, the installation of a side stand had to be abandoned.

Therefore, it is an object of the present invention to provide a side stand that can be attached to a motorcycle having a cowling without impairing the effectiveness of the cowling.

In order to achieve this object, the side stand of the present invention is characterized in that a cover plate, that is, a cowl, is fixed to the outer side of the side stand, which forms a surface that is substantially integral with the cowling when stored. According to the present invention, when the side stand is raised to the retracted position during driving, the outer surfaces of the cowl and the cowling become the same surface, which improves the aerodynamic performance of the cowling and widens the design range.

The present invention will be explained below with reference to the accompanying drawings. FIG. 1 is a side view of a conventional motorcycle that has a cowling 1 that covers the front part of the vehicle body and a side stand 2. FIG. 3 is the front wheel, 4 is the rear wheel, 5 is the body frame,
An engine 6 is mounted on the front lower part of the vehicle body frame 5 and is attached to the frame 5. A cowling 1 is provided to cover the front of the cowling.
In the illustrated example, the cowling 1 is a full-face ring that covers the front part of the vehicle body from the top to the bottom, but some motorcycles have it divided into a fairing that covers the upper part and an under cowl that covers the lower part. In this specification, the full fairing and the under cowl are collectively referred to as a cowling. The cowling 1 extends rearward along the front side of the vehicle body, improves the aerodynamic performance of the vehicle by rectifying the air flowing along the side, and guides the air flowing into the cowling from an opening provided at the front. and guided around the engine 6 to efficiently cool the engine. Cowling 1 also affects the aesthetics of the car body and has a great design effect.

The side stand 2 is pivotally connected to the vehicle body frame 5 at the front of the lower side of the vehicle body, and when the vehicle is running, it is flipped up by spring force into the retracted position shown by the solid line in the figure, but when the vehicle is stopped, it is rotated downward and the vehicle is rotated downward by the chain line 2'. When lowered to the position shown, it becomes a support that supports the weight of the vehicle between it and the ground. Therefore, as mentioned above, the side stand 2 is attached to the front part of the vehicle body due to the position of the center of gravity of the vehicle body, ease of use, etc.
However, since this side stand must swing between the retracted position 2 and the support position 2' as described above, it cannot be completely covered by the cowling 1. As shown, cowling 1 was extended only to the vicinity of the front of side stand 2. The cowling 1 was provided with a relief or cutout 7 near the side stand 2.

An embodiment of the present invention, which is an improvement on such a conventional motorcycle, is shown in FIG. 2 and subsequent figures. In these drawings, similar parts to those in FIG. 1 are given similar reference numerals.

2 and 3 are enlarged side views of the vicinity of the side stand of the motorcycle, and the relationship between the mounting position of the side stand 2 and the entire vehicle body is the same as that in FIG. 1. The side stand 2 is pivotally mounted on a down tube 8 constituting the vehicle body frame via a pivot 9. The cowling 1 extends further to the rear than in the case shown in FIG. 1, and almost covers the engine. Reference numeral 10 denotes a step, and the side stand 2 is provided at a position where it does not interfere with other vehicle body parts.

A notch 11 is provided in the cowling 1 at a position corresponding to the side stand 2, which serves as a relief when the side stand 2 rotates from the retracted position shown in FIG. 2 to the extended position shown in FIG. passes through this notch 11 and pivots 9
This side stand 2 can be rotated around the
A cover plate or cowl 12 is fixed to the outer side of the cover plate. This cowl 12 has a shape that almost matches the notch 11, and as shown in FIG. Forms a substantially integral outer surface that is continuous with the outer surface. Therefore, the airflow that passes along the outer surface of the cowling 1 during running is not disturbed by the notch 11 and flows along the substantially integral surface formed by the cowling 1 and the cowl 12. It flows smoothly.

Since the cowl 12 is fixed to the side stand 2, when the side stand 2 is projected downward to support the vehicle body, it rotates together with the side stand 2 and comes out of the notch 11. FIG. 4 is a front view showing the vehicle body supported by the protruding side stand 2.

The cowl 12 is fixed to the side stand 2 with screws 13 and nuts 14, as shown in FIGS. 5 and 6. That is, a mounting seat 15 is provided protruding from the middle portion of the rod-shaped side stand 2, and a mounting boss 16 is provided protruding from the inner surface of the cowl 12 at a position facing the mounting seat 15. The mounting boss 16 is provided with a nut 14, and the end face of the mounting boss 16 is brought into contact with the end face of the mounting seat 15, and the screw 1 is inserted through the hole provided in the mounting seat 15.
3 to the nut 14, the cowl 1
2 and the side stand 2 are fixed to each other with a sufficient gap 17 (FIG. 5) interposed therebetween.

One end of a spring 18 is also attached to the outside of the intermediate portion of the side stand 2, and the other end of the spring 18 is attached to the vehicle body at a position displaced from the pivot 9. During driving, the side stand 2 is pressed and held in a substantially horizontal retracted position along the side of the vehicle body as shown in FIG. 2 by the force of the spring 18.
When it is rotated past the dead center position around the pivot 9 against the force of , and comes into contact with a suitable stop, it is held in the extended position by the force of the spring 18.
During such rotational movement of the side stand 2, the spring 18 moves relative to the side stand 2, so there is a sufficient gap 1 between the side stand 2 and the spring 18 to allow the above relative movement.
7 is provided. The spring 18 may be provided inside the side stand 2, that is, on the opposite side from the cowl 12, and in this case, it is not necessary to provide the gap 17.

7 and 8 show other embodiments of the invention. In this embodiment, the side stand 2 is positioned rearward from near the rear end of the cowling 1 when it is stored, and therefore the cowling 1 is not provided with a notch as in the previous embodiments. However, in this embodiment as well, a cowl 12 is fixed to the side stand 2, and this cowl 12 forms a surface that is substantially integral with the cowling 1 when the side stand 2 is stored, so that the same effect as in the previous embodiment can be obtained.

As described above, in the present invention, since the cowl that forms a substantially integral surface with the cowling when stored is fixed to the outer side of the side stand, the integral continuous surface formed by the cowling and the cowl during driving is fixed. The sides of the vehicle are covered all the way to the rear, improving aerodynamic performance and increasing the cooling effect of the lower part of the engine.

Also, since the cowling surface becomes substantially wider,
The scope for effective design is also expanded.
