Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a windshield with a roof that can be attached to a motorcycle to prevent wind and rain from the front and the top of a driver.

(Prior Art) In recent years, an all-weather type motorcycle is widely used in which a box-shaped vehicle body having both side surfaces opened is attached to the motorcycle so that the motorcycle can be easily driven even in the wind and rain.

Originally, this box-shaped car body should be weighed as much as possible in order to be mounted on a low horsepower motorcycle, and is usually made of a thin synthetic resin plate, and hits the rear end of the roof part in terms of strength. It is usual that a rear wall or left and right side-by-side columns are connected to the part and the lower end thereof is fixed to a rear loading platform of the motorcycle, etc., and the whole is formed in a trapezoidal shape when viewed from the side.

(Problems to be solved by the invention) However, the conventional roof windshield has the following points to be improved.

Conventional roofed windshields are generally made of plastic in a single-layer structure, and in such a structure the strength of the part of the roof that connects to the front wall is weak, and especially the roof projects rearward from the upper end of the front wall. In the case of a canopy-shaped structure, that is, a structure without a rear wall or a pillar, there is a possibility that the roof part may be swollen upward and damaged due to a gust of wind.

In addition, the conventional windshield with a roof is integrally formed, and the motorcycle equipped with this cannot replace the entire windshield as a whole if a part of the windshield is damaged in an accident such as a collision. I shouldn't have.

Furthermore, considering driving comfort, it is preferable that ventilation be performed appropriately in summer, when the temperature is high, but the windshield covers the front of the driver considerably and blocks the wind. , I had no choice but to deal with it when it was hot and humid.

It is an object of the present invention to provide a windshield with a roof, in which the above-mentioned disadvantages of the prior art are improved.

(Means and Actions for Solving the Problem) In order to achieve the above object, according to the present invention, a waist plate portion is superposed and fixedly mounted on a front surface of a frame of a motorcycle, and a main body portion is superposed on a front surface of the main body portion. A front wheel cover portion fixedly attached integrally, the main body portion is an integral member having a roof portion protruding rearward at the upper end of the front transparent window portion connected to the waist plate portion, There is provided a windshield for a motorcycle having a hollow structure made of a thin-walled fiber-reinforced plastic in which the integral member is formed into a series of cavities inside and provided with communication holes in place to communicate with outside air. 1).

In this windshield with a roof, the roof portion is simply shaped like an eaves projecting rearward, and the whole is formed into an integral hollow structure so as to be lightweight and to maintain required strength. That is, the hollow structure means that a hollow metal shaft (hollow shaft) made for the purpose of reducing the weight, for example, can withstand a sufficient load without significantly lowering its strength as compared with a solid shaft. . Similarly, in the case of a windshield with a roof, sufficient strength can be obtained by forming the whole with a thin synthetic resin hollow body. However, in this case, a communication hole for communicating the inside of the cavity with the outside air is provided in an appropriate place. Therefore, it is possible to prevent damage due to expansion of the internal air even under hot weather. Furthermore, this windshield with roof has a structure in which two parts, the main part directly attached to the motorcycle and the front wheel cover part that uses the upper part of the front wheel of the motorcycle, are overlapped to further increase the strength and prevent accidents such as collisions. On the other hand, the safety is maintained. In other words, in an accident such as a collision, the front wheel cover part first hits and breaks, but in most cases the damage is stopped here, and since this part acts as a bumper, the main part is not affected. It is rare and therefore safer for the driver, and it is economical to replace only the damaged front wheel cover with another. In particular, when using a motorcycle equipped with a windshield for business use, the front wheel cover portion can be easily replaced with another motorcycle, so that the motorcycle does not have to be rested, which is efficient. Also, since the front wheel cover part can be easily attached and detached, by replacing it with a different design front wheel cover part, the design as a whole bike will be redesigned and it will be possible to meet various needs of users. become.

Further, according to the present invention, the waist plate portion is composed of a main body portion which is fixedly attached to the front surface of the frame of the motorcycle, and the main body portion is eaves rearward at the upper end of the front transparent window portion connected to the waist plate portion. An integral member having a roof portion protruding in a shape and a front wheel cover portion connected to the waist plate portion,
Further, the integral roof part is provided with a roof windshield for a motorcycle, which is formed in a hollow structure made of thin-walled fiber-reinforced plastic, the inside of which is made into a series of cavities and provided with communication holes in place to communicate with outside air. Claim 2).

This windshield with roof has the same advantages as the windshield described above (claim 1) in terms of strength. In these roofed windshields, a plurality of communication holes communicating with the outside air are provided, one of which is connected to an intake hole provided on the front surface of the front wheel cover portion, and the other one is opened to the inner surface of the upper portion of the main body portion to discharge the outside air. It is preferable to form it (claim 3). This makes it possible to effectively prevent damage due to expansion of the internal air under hot weather even though the main part is composed of a hollow structure made of fiber reinforced plastic, and also to the driver. Ventilation can be performed appropriately, and weather resistance and driving comfort are improved.

Further, according to the present invention, the waist plate portion is superposed and fixedly mounted on the front surface of the frame of the motorcycle, and the main body portion is superposed on the front surface of the main body portion and integrally fixedly mounted or integrally formed with the main body portion. A front wheel cover portion, the main body portion is an integral member having a roof portion protruding toward the rear of the upper end of the front transparent window portion connected to the waist plate portion,
Further, from the rear end of the roof portion, a rear wall integrally formed with the roof portion is formed continuously, or two pillars standing in parallel are continuously provided, and the integrated member is formed as a thin single-layer structure made of fiber-reinforced plastic. Further, in the upper part of the front transparent window portion of the main body portion, an opening for taking in outside air, a visor arranged in the vicinity of the opening for promoting the taking in of outside air, and an outside air intake amount are adjusted. Provided is a windshield with a roof for a motorcycle, which is provided with an opening adjustment door for operating the windshield. In this case, the comfort due to ventilation is improved as in the case of the windshield described above.

(Embodiment) An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a side view of a motorcycle having a roof windshield of the present invention. As this bike, an appropriate one that is commercially available is used, but a three-wheel scooter is generally common because the stand operation is easy.

The roof windshield of the present invention comprises a main body portion 2 and a main body portion 2 which are fixedly mounted directly on the front surface of a frame 1 of a motorcycle.
And a front wheel cover portion 3 which is fixed to cover the lower half portion of the main body portion and the upper portion of the front wheel of the motorcycle.
As shown in FIG. 2, the main body part 2 covers the front part of the seat of the motorcycle, and the front transparent window part 5 and the roof part 6 are sequentially connected to the waist plate part 4 which is made to have a width exceeding the both ends of the steering wheel. The front wheel cover portion 3 has its upper half portion overlapped with the lower front half of the main body portion 2, and the lower half portion is formed into a front wheel mudguard 7 that extends forward in a hemispherical shape, and A square hole 8 for mounting a headlight and round holes 9, 9 for mounting a winker lamp are provided in each half. The main body portion 2 and the front wheel cover portion 3 are each made of fiber reinforced plastic (FRP), and in particular, the main body portion 2 is formed as a relatively thin hollow structure having a hollow inside as described above.

The main body portion 2 is a waist plate portion 4 as shown in FIGS.
Except for the central part, the whole is made into a blow-molded hollow structure, and the polycarbonate transparent body 10 of the waist plate part 4 and the front transparent window part 5 is sandwiched from the left and right as is clear from the sectional view of FIG. From the window frame and the front transparent window 5 to the roof 6
The portions connected to are a series of hollow portions a, b, b, c, c that communicate with each other. Then, in the portions corresponding to the hollow portions a and c, c, there are communication holes 12, 1 communicating with the outside air, respectively.
1,11 have been opened. In this embodiment, in particular, the communication holes 11 and 11 are formed as outside air suction holes, and the communication holes 12 are formed as outside air ejection holes, and ventilation is performed using these communication holes. That is, the front wheel cover portion 3 is provided with intake ports 13, 13 at positions substantially corresponding to the communication holes 11, 11 of the main body portion 2, and the communication hole 12 has an opening control door 14 as shown in FIG. Is attached, the outside air is taken in through the intake ports 13 and 13 and the cool air is blown above the driver's head from the outside air ejection hole which is the communication hole 12 during traveling.

To attach the roof windshield of this invention to a motorcycle, after removing the front cover (front loading platform) and headlights of the motorcycle, the main body portion 2 is provided with the bolt holes 15 provided in the lower half portion thereof. The front windshield main body 3 is fixedly mounted by engaging the front cover mounting bolts of the same, and the front wheel cover portion 3 is also engaged with the bolt holes of the mounting rod (not shown) laterally provided on the rear surface thereof to the above mounting bolts. 2 After stacking on the front surface and tightening together to form a windshield with a roof, the headlights, winker lamps, etc. described above may be incorporated into the square hole 8 and the round holes 9, 9 of the front wheel cover portion 3, respectively.

The present invention has been described above with reference to an embodiment, but the present invention is not limited to this, and various modifications and changes can be made.

For example, the main body portion and the front wheel cover portion may be integrated into a double structure. In this case, there is no advantage as described above that the two parts are configured separately,
In terms of structural strength, it has the same advantages as described above.

Further, according to the present invention, as shown in FIGS. 7 and 8, the rear portion of the roof portion 6'is connected to the two columns 20 or the rear wall (not shown) and the main portion In the case where 2'is formed in a single structure made of fiber reinforced plastic, an opening 21 for taking in outside air is formed above the transparent window portion 5, and a visor 22 is provided in a roof portion 6'slightly above the opening 21. Along with the mounting, the opening 21 may be provided with an opening adjusting door 23 similar to that shown in FIG. In this case, there is an advantage that the ventilation comfort described in the above-described embodiment can be obtained.

(Effect of Device) As described in detail above, according to the device of claim 1,
The roof portion 6 is simply made of an eaves-like member protruding rearward,
It is convenient to handle because there is no rear wall or columns behind it, and the main body part 2 which is a hollow structure can be maintained with sufficient strength as a whole because it is a hollow structure.
Since the upper half of the plate-like front wheel cover portion 3 is overlaid and integrally assembled, the strength is further compounded. In particular, where the front wheel cover portion 3 and the main body portion 2 overlap each other, the front wheel cover portion 3 has the same strength as the double structure although it has a single structure. Further, since the front wheel cover portion 3 is formed as a part of the windshield with a roof and is independent of the rotation of the front wheel, safety is maintained during driving. That is, in the case of the conventional type in which the front wheel is covered as it is, when another object collides from the side, the front wheel is forcibly laid sideways, and as a result, there are many accidents of falling, but in this invention the shock of collision is generated. Is absorbed by the front wheel cover portion 3 and the directionality of the front wheels is less likely to be changed. Therefore, in the past, in the case of a collision with another object, the entire windshield was damaged and was unusable. However, in the case of the windshield of the present invention, the front wheel cover portion 3 is damaged only by the damage, and Part 2 is not affected.

Further, since the front wheel cover portion 3 can be easily attached and detached,
By replacing it with another front wheel cover part with a different design, you can change the design of the bike to your liking,
It can meet the needs of users.

According to the invention of claim 2, as in the case of the invention of claim 1, the conventional drawback in terms of strength is improved.

According to the third aspect of the invention, in addition to the advantages of the first and second aspects, there is an advantage that the driver is appropriately ventilated, so that comfortable driving can be performed even under conditions such as in the hot sun.

According to the invention of claim 4, as in the case of the invention of claim 3, there is an advantage that a comfortable driving can be performed even under the conditions such as the hot sun.
