Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cowling device C for a motorcycle or a tricycle.

In recent years, even in vehicles such as motorcycles that are intended to travel on rough terrain, opportunities to drive at high speeds on expressways have increased due to the increase in engine output, and the impact of driving wind on drivers has increased accordingly. It's becoming a big thing. Therefore, it is possible to install a cowling to protect the driver from the wind while riding, but if a large cowling with a transparent windscreen partial sound is installed on this type of motorcycle for riding on rough terrain, it is possible to install a cowling that protects the driver from the wind while riding (= Due to the presence of the C-ni blind screen in front of the driver's eyes, problems arise such as the original feeling of freedom and lightness being lost.

The present invention has been made based on the above circumstances.A transparent windscreen is housed inside a small cowling body surrounding the headlight, and this windscreen is provided so as to be able to protrude upward. When in use, C2 pulls out this wind screen upwards, and when it is no longer needed (C2 is stored inside the cowling body), creating a sense of freedom unique to vehicles such as motorcycles whose main purpose is riding on rough terrain. The purpose of the present invention is to provide a cowling device that is not only light but also has no effect on maneuverability.

The present invention will be explained below based on one embodiment C2 shown in all the drawings (2).

Figure 1 shows the entire motorcycle, where 1 is the frame, 2 is the front fork, 3 is the fuel tank, 41d, i/-),
5 each indicates an engine. The engine 5 of this embodiment is of a water-cooled type, and a radiator 6 for cooling the engine 5 is provided on both sides of the lower front end of the fuel tank 3.

The upper part f of the front fork 2 and the bifurcated headlight 7 are surrounded by a small cowling 8, and details of this cowling 8 are shown in FIGS. 2 and subsequent figures. That is, 1θ is a cowling body made of an opaque synthetic resin material, and has a substantially box shape that completely surrounds the headlight 7. Cowling body 1
The opening is continuous from the rear surface to the upper surface of 0 (2 and 52), and the front surface C2 has an opening 12 through which the front lens of the headlight 7 faces. The lower side C2 has elongated air guide holes 13, 13, and the inner surface C2 of the cowling body 10 has the air guide holes 13.
, 13 are integrated with air guide plates 14 and 14 extending toward the rear radiator 6 side C.

As shown by the arrow in FIG.
The cooling efficiency of the radiator 6 is improved.

Further, the upper side of the opening 12 on the front surface of the cowling body 10 forms an inclined surface 15 which is inclined upward (=advance C1, therefore, backward).The inner side of this inclined surface 15 (
- The windscreen 16 can be rotated upward and retracted (two are provided).

The wind screen 16 is made of a transparent synthetic resin material C2 such as polycarbonate.

There are two mounting structures C for this wind screen 16, and the third
To explain with reference to the figures to FIG. 6, the inclined surface 15
The left and right sides of the are bent rearward to form opposite side walls 17.17, and these side walls 17.17
Guide members 19 and 19 are fixed to the opposing surface C2 of the guide members 19 and 19 via rivets 18. The guide member 19.19 is connected to the above-mentioned both sides W171Z7 in the vertical direction, that is, in the inclination direction of the inclined surface 15 (2).
0f, and this guide member 19.19 has two sliding chambers 2θ, 20g (2, its longitudinal direction f1
A slit-shaped groove 21° 21 is formed along the line. A bolt head 23.23 of a lock bolt 22.22 is housed inside the sliding chamber 20.20, and its threaded portion 24.24 is led out through a groove 21.21. These lock bolts 22° 22 have grooves 21, 2
The threaded portions 24 of the lock bolts 22 and 22 pass through the lower end of the windscreen 16 and both left and right ends of the fixed support fittings 25, and the lock bolts 22 and 22 are provided so as to be movable up and down while being guided by the windscreen 16. - Exclusive to the inside of the clean 16, and this lead-out end (2) is screwed with a disc-shaped nut 26, 26, respectively. Therefore, when the nut 26, 26f is tightened, the support fitting 25 is guided. Part 19
．． 19, the entire windscreen 16 is fixed to the cowling body 10, and vice versa (when loosening the nut 26 and 26, the windscreen 16 becomes free C).
1, it becomes possible to move C2, and when this window cleaner 16 is pushed down by the maximum C2, the direct weight is stored inside the inclined surface 15 as shown by the imaginary line in FIG. Also, the center g2 of the inner surface of the inclined surface 15 is connected to the groove 2.
1. The hook 27 located on the upper end side of 21 and protruding from the center of the support metal fitting 25 is removable. It is designed to be positioned when the windscreen 16 is fully maxed out (2) and pulled up (2).

A soft felt 29 is attached to two surfaces of the protrusion 28 facing the windscreen 16 to prevent the windscreen 16 from being scratched.

According to the cowling 8f2 with such a configuration, for example, when driving continuously on a highway (the second is a nut 26
．． Loosen 26f and move the windscreen 16 to the inclined surface 15.
Pull out the upper f2 and tighten the nut again f26.26'f. Because of this (2), since the windscreen 16 is fixed in a state where it protrudes above the slope 15, the influence of the wind on the driver while driving is reduced, and the driver can be protected from the entire wind pressure.

On the other hand, when the C2 windscreen 16 is not required, for example when driving on rough ground (the second case is when the nut 26
．． If you loosen the nut 26f and push down the windscreen 16, the windscreen 16 will be stored inside the inclined surface 15, and then tighten the nut 26.26f again.
5 inside C2 is fixed.

In this way, the windscreen 16 can be freely opened by protruding above the cowling main body 10 or recessed into the main body 10, depending on the driving situation or necessity. Moreover, since the cowling body 10 itself is small enough to surround the Tudorite 7, there is little increase in weight, and it does not affect the maneuverability of this type of motorcycle when riding on rough terrain. Furthermore, since the windscreen 16 is stored inside the cowling body 10, there is an advantage that the appearance is not damaged when the windscreen 16 is not in use.

In addition, in the above embodiment, a wind guide plate was provided that extends toward the cowling body (the radiator side), but if the engine is an air-cooled type, it may be provided on the cylinder side of the ennon (it is sufficient to provide it facing both directions).
-+ The air guide plate of the octopus is integrally constructed with the cowling body (
= Not limited to this, it is also possible to rivet a separate item to the cowling body.

Furthermore, the mounting structure of the cowling main body is not limited to the above embodiment. A groove is formed along the direction, and two or more bolts are inserted into this groove and tightened with a wing nut or the like from the outside of the cowling body.

According to the present invention described in detail above, the windscreen is placed inside the small cowling body that surrounds the headlight, and the windscreen is provided so that it can protrude upwards. Depending on the situation or need (you can use the double windows as you like), the feeling of freedom and nimbleness characteristic of a vehicle that is primarily intended for driving on rough terrain is not impaired, and C1 is achieved.In addition, there is little weight increase, so there is no impact on maneuverability. This has the advantage that it does not affect the windshield's appearance (-), and when the windscreen is not in use, the screen is stored inside the cowling body, so the appearance is not impaired.
