Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a flash lamp mounting structure for a motorcycle with a cowling.

(Prior Art) Generally, in a motorcycle with a cowling, a cowling stay 3 is fixed to a head pipe 2 at the front end of a pipe frame 1, and the front end of a cowling body 4 is supported by the cowling stay 3, as shown in FIG. ing. Flasher lamps 6 (only the left side is shown) for direction indication are attached to the cowling body 4 on both the left and right sides of the headlamp 5. 7
is a front wheel, 8 is a rear wheel, 9 is an engine, and 10 is a seat.

The mounting structure of the right flasher lamp in the - cross section of FIG. 3 is as shown in FIG.
3 protrudes horizontally in one piece, and a male thread 14 that is one step thinner at the tip of this boss shaft 13 fits into a hole 17 in a bottom vertical wall 16 of a recess 15 provided in the cowling body 4, and a nut 18 connects the vertical wall 16 to the boss. It is fastened to the end face 19 of the shaft 13. The boss shaft 13 passes through a hole 21 of a hollow cylindrical intermediate stay 20 made of a flexible material such as resin or rubber. The intermediate stay 20 is attached to the boss 12 by tightening the nut 18.
and the vertical wall 16, thereby preventing the flasher lamp 6 from wobbling. 22
is the lead wire.

However, according to the structure shown in Fig. 4, although the installation workability is good, the flasher lamp 6 is damaged when it falls, and at the same time the cowling body 4 is damaged by the impact.
is also easily damaged. The cowling body 4 is generally a large resin-made component and is expensive, resulting in a heavy burden on the user.

FIG. 5 shows another conventional structure, in which an intermediate stay 20 made of resin or rubber is passed through a hole 24 in the cowling body 4, and is attached to the cowling stay 3 within the cowling body 4 with a bolt (external thread 14), a nut 18, etc. ing. The hole 24 is formed by a rubber grommet 25 attached to the cowling body 4, and the intermediate stay 20 is in elastic contact with the grommet 25 over its entire circumference. 26 is a vibration-proof damper made of a thick rubber plate or the like, and 27 is a washer. According to this structure, when the vehicle falls over, the strong cowling stay 3 receives the impact from the flasher lamp 6, so damage to the cowling body 4 can be reduced, but the installation is done inside the cowling, resulting in poor assembly workability. As a prior art, it was published in 1983
There is No. 4709.

(Purpose of the invention) The object of the invention is to provide good assembly workability and to reduce damage to the cowling body by making it easier to separate the flash lamp from the cowling body in the event of a fall.

(Structure of the invention) The first invention is to fix the bottom of a hollow bottomed cylindrical intermediate stay made of rubber-like elastic material to the flatsher lamp, and to fit the tip of the intermediate stay into a hole having approximately the same shape as the intermediate stay mounting hole of the cowling body. A joint part, a step part that contacts the outer edge of the intermediate stay mounting hole, and a step part that contacts the inner edge of the intermediate stay mounting hole are provided, and a metal or resin groove is provided in the annular groove provided on the inner surface of the protruding part in the cowling body of the intermediate stay. This is a flasher lamp mounting structure for a two-wheeled motor vehicle with a cowling, characterized in that the flasher lamp is held on a cowling body by fitting a plate.

When the flash lamp receives an impact such as when falling down, the fitting portion of the intermediate stay comes off from the intermediate stay mounting hole of the cowling body, preventing transmission of impact force to the cowling body. A plate made of metal or resin prevents deformation of the intermediate stay inside the cowling body, and increases the rigidity with which the flash lamp is held against the cowling body. Therefore, the size of the plate may be large or small regardless of the intermediate stay mounting hole.

A second invention is a flat lamp mounting structure for a two-wheeled motor vehicle with a cowling, characterized in that the size l1 of the intermediate stay fitting portion in the first invention is made larger by the size l2 of the metal or resin plate. be.

When the flash lamp receives an impact force, the tip of the intermediate stay also comes off outward together with the plate.

The third idea is to fix the bottom part of a hollow bottomed cylindrical intermediate stay made of rubber-like elastic material to the flatsher lamp, and at the tip of the intermediate stay, a fitting part having approximately the same shape as the intermediate stay mounting hole of the cowling body, A step part that contacts the outer edge of the stay mounting hole and a step part that contacts the inner edge of the stay mounting hole are provided, and only when an impact force is applied to the flash lamp, the intermediate stay deforms and each step part closes the intermediate stay mounting hole. This is a flash lamp mounting structure for a two-wheeled motor vehicle with a cowling, characterized in that each of the stepped portions is made low enough to allow passage inward or outward. If the material of the intermediate stay is limited and, for example, resin or the like or hard rubber is used, the holding rigidity of the intermediate stay can be ensured even without using the plate.

(Example) In FIG. 1, the boss 12 of the flash lamp 6
is equipped with a short boss shaft 13, and this boss shaft 13 is made of a soft material equivalent to rubber (rubber-like elastic body) and has a hole 21 formed in the bottom part 30a of a hollow-bottomed cylindrical intermediate stay 30.
By fitting the intermediate stay bottom 30a into the boss 12 and screwing the nut 18 onto the concentric male screw 14,
It is tightened. 31 is a washer. The open tip portion 30b of the intermediate stay 30 has a fitting portion 33 having approximately the same cross-sectional shape as the intermediate stay mounting hole 32 on its outer circumferential surface, an outer step portion 34 and an inner step portion 35 that sandwich the fitting portion 33. The portions 34 and 35 are in elastic contact with the outer and inner peripheral edges surrounding the hole 32. The outer periphery of a sheet metal plate 37 for holding the shape of the intermediate stay tip 30b is fitted into an annular groove 36 provided on the inner surface of the protrusion inside the cowling body of the intermediate stay tip 30b. Stay tip 30
The inward flange 39 of b is fastened to the plate 37. The profile of the plate 37 is slightly smaller than the intermediate stay attachment hole 32. That is, l shown in FIG.
1 is the long axis of the intermediate stay mounting hole 32, l2 is the long axis of the plate 37, and there is a relationship of l1>l2, l1
-l2 is, for example, 2 mm (the difference around the circumference is 1 mm). Moreover, the height of the inner and outer step portions 34 and 35 is as small as, for example, 1 mm with respect to the intermediate stay attachment hole 32 (longer diameter l1) (l3-l1=2). The plate 37 has a hole 40 in the center through which the lead wire 22 passes.

In order to attach the flasher lamp 6 to the cowling body 4, the flasher lamp 6 must be installed in the previous process.
The intermediate stay 30 is fixed with the nut 18, the fitting part 33 of the intermediate stay 30 is elastically pushed into the intermediate stay attachment hole 32 of the cowling body 4, and then the annular groove 3 is inserted from the inside of the cowling body 4.
A plate 37 is fitted into the inside of the flange 39, and the plate 37 is fixed to the flange 39 with machine screws 38 to prevent it from coming off. The material of the plate 37 is sheet metal,
It may be made of resin.

When the impact force shown by arrow P1 acts on the flasher lamp 6 from the lateral direction during a fall, the intermediate stay 30
The tip 30b of the outer step 34 is deformed and the outer step 34
It passes through the inside and enters into the cowling body 4.
Furthermore, when an impact force is applied in the direction of arrow P2 due to a fall during running, the intermediate stay tip 30b is deformed so that the front step 35a passes outward through the hole 32, and the rear step 35 continues to deform. The flash lamp 6 also passes outward through the hole 32, and the flash lamp 6 is thus removed from the cowling body 4.

FIG. 1a shows another embodiment in which the intermediate stay 30 is connected to the boss 12 of the flat lamp.
The distal end portion 30 of the intermediate stay 30 is formed integrally with a relatively hard resin or hard rubber.
A reinforcing plate as shown in FIG. 1 is not attached to the inner surface of b.

(Effect of the invention) According to the first invention, the flat lamp 6 and the cowling body 4 are connected to the intermediate stay 30 made of a rubber-like elastic body.
Since the tip 30b of the intermediate stay 30 is connected to the cowling body 4 by connecting it with
It becomes easier to come off from the cowling body 4, and damage to the cowling body 4 is reduced. In other words, during a standstill, the outer step portion 34
When the intermediate stay 30 receives a load, the intermediate stay tip 30b deforms and the intermediate stay 30 comes off to the inside of the cowling body 4, so that damage to the cowling body 4 is reduced. Furthermore, when the vehicle falls while running, the inner step portion 35 is deformed and detached from the cowling body 4 to the outside, and damage to the cowling body 4 is similarly reduced.

Next, according to the second invention, since the plate 37 with the relationship l1>l2 is attached, the shape of the intermediate stay tip 30b is maintained, and it can be removed inwardly or outwardly only when a predetermined impact force is applied. be able to.
Also, when the plate 37 is fixed with the small screws 38,
The load when it comes off outward can be increased,
Effective in preventing theft. In other words, the rigidity of holding the intermediate stay increases.

According to the third invention, by forming the intermediate stay with a relatively hard elastic material such as resin or hard rubber, the above-mentioned reinforcing plate can be omitted, and furthermore, the tip of the intermediate stay can be adjusted appropriately when an impact force is applied. The cowling body is deformed appropriately, passes through the intermediate stay mounting hole inwardly or outwardly, and comes off without causing damage to the cowling body. Therefore, costs can be reduced by reducing the number of parts.
