Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a side cover device for a motorcycle.

(Prior art) Generally, in the frame below the seat of a motorcycle, there is a space sandwiched between the engine and the rear wheel that is approximately an inverted triangle when viewed from the side, and the upper half of this space A battery and other electrical components, an air cleaner, etc. are built into the body, a toolbox is built into the lower half, and a brake connection system is located on the right side of the body, while a chain for rear wheel drive passes through the left side. However, in order to hide these, side covers made of resin or the like have traditionally been used. However, if the battery, air cleaner, tool box, etc. are covered with one side cover on each side, the side covers will be large, the mold cost will be high, and it will take time to make the molds. Moreover, the large side cover must be removed in its entirety just to take out a simple tool, which is time-consuming. On the other hand, the upper half of conventional side covers has a large area and is easily noticeable, so even if you try to paint or plate only that part, it is almost impossible to work on the upper half alone, and it is not very noticeable. The lower half must also be painted or plated, and the entire body must be molded from an expensive resin suitable for painting or plating (such as ABS resin), which tends to increase costs. As a countermeasure to this problem, it is conceivable to divide the side cover into a large upper side cover and a smaller lower side cover. However, in this case, the front end of the upper side cover on the engine side occupies a position alongside typical metal mechanical parts such as cylinders and carburetors, so from the viewpoint of aesthetic balance, it is recommended to apply plating to give it a metallic color. preferable. Plating is also effective in reflecting engine heat so that it does not transfer to the driver's knees. For this reason, conventionally, only the part of the side cover immediately after the engine was made of a separate plated part (made of metal or resin), but in that case, the number of attachment parts increased and the structure became complicated. It also takes time to put on and take off. As a prior art, there is Utility Model Application Publication No. 120287/1983.

(Purpose of the invention) This invention divides the side cover into two parts: a large upper side cover that is opened and closed less frequently, and a smaller lower side cover that is opened and closed more frequently. The purpose of this invention is to enable manufacturing with easy resin, reduce costs by downsizing the mold, and allow plating to be applied only to the engine-side front half of the upper side cover, which extends relatively long and thin from front to back.

(Structure of the invention) The invention divides the side cover that covers the space in the frame between the engine and the rear wheel into a large upper side cover and a small lower side cover, and the front half of the upper side cover on the engine side. A side cover device for a motorcycle, characterized in that the rear half of the upper side cover is divided by a narrow and deep groove, the front half of the upper side cover is plated, and the rear half is painted. be.

The upper side cover is divided into the front and rear parts by a narrow and deep groove, so after plating the entire part, masking the area in front of the groove, and then painting the rear part. administer. As a result, the first half and the second half appear as if they were two completely independent parts, and there are a total of three mounting locations, for example, two locations on the front and back of the top end and one location on the bottom end.

(Example) In FIG. 1 showing the right side of a motorcycle to which the present invention is applied, 1 indicates an upper side cover;
2 is a lower side cover, which is located below the seat 3, occupies a position sandwiched between the engine 4 and the rear wheel 5, and narrows as it goes downwards when viewed from the side (Fig. 1). It covers an inverted triangular space. The above-mentioned inverted triangular space is formed in the center of the frame 6, and the upper side cover 1 covers the battery and other electrical components directly under the seat 3, as well as the air cleaner behind the engine 4 (on the left side in Fig. 1) (both of which are shown in Fig. 1). (not shown). The lower side cover 2 covers the tool box or also serves as the lid of the tool box. 7 is the radiator, 8 is the fuel tank, 9 is the handle, 10 is the front fork,
11 is a front wheel, and 12 is a rear fender.

In the present invention, the side cover is divided into two parts: a large upper side cover 1 that is long in the front-rear direction, and a relatively small lower side cover 2. The highly visible upper side cover 1 is designed so that it can be painted or plated. Made of high quality resin (e.g. ABS plastic). The battery, other electrical components, and air cleaner covered by the upper side cover 1 may be inspected less frequently, so the upper side cover is opened and closed less frequently. On the other hand, since the lower side cover 2 is a small, inconspicuous component, there is no need to use high-quality resin that can be painted or plated, and it can be made of inexpensive colored resin (for example, polypropylene).

The front half 1b of the upper side cover 1 occupies a position immediately behind the engine 4 and the carburetor behind it, and is integrally continuous with the rear half 1c via a narrow and deep groove 13, and the front half 1b is made of metal. The rear part 1c has a brightly colored chrome plating or other plating surface, and the rear part 1c has a painted surface that is modest enough to make the front part 1b stand out. To manufacture this upper side cover 1, the entire body is molded from ABS resin, the entire body is plated, and then the rear half 1c is coated with a predetermined coating while the front half 1b is masked. The width of the groove 13 is approximately 1 mm as shown in Figure 6.
It is made of moderately narrow and deep grooves, and the cut groove 13
The ribs 14 forming the upper side cover 1 extend downwardly toward the rear, increasing the rigidity of the relatively long upper side cover 1.

Next, the mounting structure of the upper and lower side covers 1 and 2 will be explained. The upper side cover 1 is provided with one protrusion 15 on the inner surface of both the front and rear ends, and each protrusion 15 is press-fitted and held in a grommet 17 fitted into a hole in a frame side bracket 16 as shown in FIG. The lower edge portion 1a of the upper side cover 1 forms a flange that is lower than the upper portion thereof.
A is placed on a bracket 18 protruding from the frame, and is fixed onto the bracket 18 by screwing a screw 19 into a weld nut 20 on the inner surface of the bracket 18. The lower edge 1a of the upper side cover and the screw 19 are covered by the lower side cover 2, and a lock bar 22 of a lock 21 attached to the lower side cover 2 engages with the bracket 18. The lower side cover 2 has a lock 21 at the rear end of the upper edge, and a T-shaped protrusion 2 at the inner surface of the upper and lower ends of the front edge.
3 (FIG. 3), and this protrusion 23 is held by being fitted from the front into a front-opening hatch channel-shaped locking piece 24 provided on the frame. A buffer rubber 25 (FIG. 4) is attached to the locking piece 24, and the rubber 25 has a U-shaped recess 26 for receiving the small diameter shaft portion 23a of the protrusion 23.
(Figure 5).

To remove the lower side cover 2 to take out tools, first insert a key (not shown) into the lock 21, turn the lock bar 22 to remove the lock bar 22 from the bracket 18, and then remove the lower side cover 2 from the third position. When the protrusion 23 is removed from the locking piece 24 by shifting it forward in the direction of arrow A in the figure, the lower side cover 2 is released. When screw 19 hidden by lower side cover 2 is removed from nut 20, upper side cover 1 is removed from the second
It can be removed laterally in the direction of figure B. To attach the side cover, first attach the upper side cover 1, screw the screw 19 into the nut 20, and then tighten the screw 1.
Attach the lower side cover 2 so as to hide 9.

(Effect of the invention) As explained above, according to the invention, the side cover covering the space inside the frame 6 between the engine 4 and the rear wheel 5 is divided into a large upper side cover 1 and a small lower side cover 2. The engine-side front half 1b of the upper side cover 1 and the rear half 1c behind it are divided by a narrow and deep cut groove 13, and the surface of the front half 1b of the upper side cover 1 is plated, and the rear half 1c is Since the surface is painted, the following special effects can be obtained. In other words, by masking the first half 1b and then painting the second half 1c, the first half 1b and the second half 1c appear as if they were separate parts, and also look like the engine 4, carburetor, etc. By giving the front half 1b a metallic color that lines up with metallic-colored mechanical parts, it is possible to achieve a balance in appearance, resulting in a product that improves the aesthetics and attracts the attention of young people. Moreover, since the upper side cover 1 has an integral structure with the front half 1b and the rear half 1c, it can be securely fixed to the frame 6 in a total of three places, two on the upper side and one on the lower side. The number of parts is kept to a minimum, making it easy to attach and detach. The simple structure also reduces manufacturing costs. The ribs 14 surrounding the grooves 13 provide an inclined reinforcing structure to the upper side cover 1 that extends relatively long in the front and back, increasing the overall rigidity and causing the upper side cover 1 to curve when the upper side cover 1 is attached or detached. This makes it possible to reliably prevent a decrease in work efficiency. Another advantage is that it can prevent vibrations during driving. Cut groove 13
Since the surface is deep, painting work after masking becomes easier. In addition, since the large top side cover 1 that stands out and the small bottom side cover 2 that is not very noticeable are separated, the top side cover 1 is made of commercial quality resin that can be painted or plated, while the bottom The side cover 2 can now be made of low-quality resin, which has the advantage of reducing the overall cost and improving the aesthetic appearance. In addition, a structure can be adopted in which the upper side cover 1 cannot be removed unless the lock 21 of the lower side cover 2 is removed. Since it is provided only on the side cover 2, it suits the actual situation of opening and closing work and improves work efficiency.
