Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a motorcycle tail end frame cover attachment device.

Traditionally, this type of frame cover installation device was designed to use bolts, setscrews, etc., and the heads of the bolts and setscrews were exposed with protrusions on the surface, making it difficult for motorcycles to be installed. The appearance could be damaged.

Furthermore, since it takes time to operate bolts, set screws, etc., there has been a need to improve the efficiency of installation work.

Additionally, in the past, the tail end frame cover and rear combination were fixed to the vehicle body frame separately, so the boundary between the tail end frame cover and rear combination could shift or open. In some cases, this can damage the appearance of the motorcycle.

The present invention is intended to eliminate the above-mentioned problems pointed out with conventional mounting devices, and therefore the object of the present invention is to provide a simple and easy to operate mounting system with a minimum number of parts. Moreover, it is an object of the present invention to provide a mounting device for a tail end frame cover of a motorcycle, which prevents the boundary between it and the rear combination from shifting or opening.

The mounting device according to the invention uses a minimum number of bolts, set screws, etc. or none at all, and since there are no protrusions on the frame cover, it does not spoil the appearance of the motorcycle.

Hereinafter, a tail end frame cover attaching device according to the present invention will be explained with reference to the accompanying drawings.

Two frames 1 are shown in FIGS. 1 and 2 extending obliquely upward and parallel to each other from around an engine (not shown).

A rear combination (Units I, housing turn signal lights and brake lights) 3 is bolted to the frame 1 via a bracket 2 attached to the rear end of the frame 1.

Stays 4 project horizontally and forwardly at intervals above and below the left and right side edges of the rear combination 3, while another stay 5 projects downward at the lower center of the branching part 1' of the frame. It is set up.

A so-called H-shaped cushion 6 made of an elastic material such as rubber and having an H-shaped cross section is fitted into a hole drilled in each of these stays 4 and 5.

Note that when the stay 5 is used for screwing, the H-type cushion is not applied.

The tail end frame cover to be installed by the device according to the present invention is designed to cover both sides of the engine and the rear wheel, as shown in FIG.

As shown in FIG. 3, bosses 9 reinforced with ribs 8 are provided to protrude inward from the inner wall surface of the tail end frame cover 7 corresponding to the stays 4 or 4 and 5, respectively. There is.

An enlarged diameter portion 9' having an outer diameter larger than the hole diameter of the H-shaped cushion 6 is formed at the tip of each boss.
Since the shaped cushion is made of an elastic material such as rubber, when the enlarged diameter part 9' is pushed into the H-shaped cushion 6, the hole expands and the enlarged diameter part 9' can pass through the H-shaped cushion 6. The outer diameter of the enlarged diameter portion 9' is dimensioned accordingly.

The procedure of the installation work using the device according to the present invention will be explained as follows.

The stepped portions (not shown) at the front end of the tail end frame cover 7 are fixed to the inside of the upper frame cover 10 by providing tongues or holes and fitting them together according to a known method.

Next, the bosses 9 protruding from the inner wall surface of the frame cover 7 are applied to the stays 4 or each of the stays 4 and 5, and pressure is applied to the frame cover 7 by hand.

When the enlarged diameter part 9' of the boss 9 pushes and expands the hole in the H-shaped cushion 6 and passes through the H-shaped cushion 6, the H-shaped cushion 6 returns to its original state, and the enlarged diameter part 9' stops the removal. do work.

Therefore, once the frame cover is installed, there is no risk of the frame cover coming off.

Note that the frame cover 7 can also be fixed to the stay 5 with screws.

Since the notch provided between the rib 8 and the bottom surface of the enlarged diameter portion 9' is sized to the width of the H-shaped cushion 6, the frame cover 7 will not wobble after being attached. do not have.

Since the device according to the present invention is configured as described above,
Although the heads of bolts and set screws are not exposed on the outer surface of the frame cover, it has a beautiful appearance.

Moreover, since the installation work can be carried out with a one-touch operation, the work is quick and easy.

Furthermore, compared to conventional mounting devices that include a large number of stays and brackets and are fixed by tightening bolts, the mounting device according to the present invention is significantly cheaper.

Furthermore, since the rubber H-shaped cushion fitted into the stay acts as a buffer, another feature of the device of the present invention is that no noise such as chatter is generated.

Also, since the tail end frame cover is fixed to the stay of the rear combination, there is no possibility that the rear edge of the tail end frame cover and the front edge of the rear combination may shift or open. This makes it possible to make the appearance of the motorcycle more desirable.

[Brief explanation of the drawing]

FIG. 1 is a partially cutaway side view of a motorcycle to which a tail end frame cover mounting device according to the present invention is applied. FIG. 2 is a partial plan view illustrating a state in which the rear combination is fixed via a bracket attached to the rear end of the frame. FIG. 3 is an enlarged partial cross-sectional view taken along line A--A in FIG. 1.
