Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a window glass cleaning device.
In particular, it relates to cleaning devices for windshields, etc. of ships, automobiles, etc.

[Prior Art] Conventionally, for example, a windshield of an automobile is equipped with a wiper, and when necessary, the wiper is activated to wipe the area of the rotation locus of the wiper.

[Problems to be Solved by the Invention] In the conventional windshield wiping operation using the wiper, the rotating operation of the wiper is projected onto the driver's field of vision in front of the driver, and furthermore, the wiper Sweeping is performed only within the range of the rotation locus, so there is a portion left to be swept.

Therefore, a technical problem has arisen that needs to be solved in order to enable cleaning of the entire surface of the window glass without obstructing the driver's view, and the purpose of this invention is to solve this problem. .

[Means for Solving the Problems] This invention was proposed to achieve the above object, and consists of doubling the window glass to form a gap between the front and rear glasses, and then forming a film-like film from the bottom of the gap. A transparent body is inserted, and the transparent body wraps around the front glass at the upper part and reaches the lower part while contacting the front surface of the front glass.Furthermore, the lower part is cleaned and wiped, and the motor is heated. It is an object of the present invention to provide a window glass cleaning device characterized in that the transparent body is formed to be rotatable.

[Function] In the present invention, window glasses are formed at the front and back, and a gap is formed between them. Then, a film-like transparent body is inserted from the lower part of the gap, and at the upper part, the transparent body is wound around the front glass surface of the window glass via a roller or the like,
Furthermore, it extends downwardly while contacting the front glass surface. Then, the roller is wound again at the lower part to form an endless body shape. In addition, the transparent body that has descended from the front glass to the bottom is passed through a detergent solution for cleaning, and then passed between sponge rollers, thereby cleaning the entire surface of the transparent body. Of course, this transparent body is rotated by the motor when necessary.

In such a case, the transparent body extends from the bottom to the top of the back of the front glass, is wound from the top, passes through the surface of the front glass, reaches the device at the bottom, is cleaned, and is inserted again into the back of the front glass. It rotates. When such a movement is repeated, the window glass is always maintained in a clean state, and since it is a transparent body and the front is viewed through the rear glass, the movement state of the transparent body is almost invisible, so there is nothing obstructing the forward view, and there is also almost no remaining area to be swept away. Furthermore, since the cleaning process is performed at the lower part as described above, most of the oil film and the like are also cleaned.

[Example] Hereinafter, an example of the present invention will be described in detail with reference to the accompanying drawings. The window glass (1) is divided into a front glass (11) and a rear glass (1b) in this embodiment. Although this window glass (1) has been applied to the windshield of an automobile, it can also be applied to all types of window glass including ships. Therefore, this window glass 0)
The front glass (!1) and the rear glass (1b) are fixed to the frame (2) on both sides with a certain gap between them. Therefore, the fixing means should not be particularly limited. Moreover, at the top of the window glass (1), a roller (
3) (3) is pivotally mounted. And the mouth, -ra (
3) The rollers (3) are arranged in parallel, one roller (3) is pressed against the other roller (3) by a spring (4), etc., and the top plate (5) and the roller (3) are in contact with each other. A rotating roller (6) can be pressed against the roller (3) to close the gap.

Further, a roller (η) is provided at the bottom of the window glass (1), and the roller (3) in front of the upper part and the lower roller (
A film-shaped transparent body (8) is wound between the 9 spaces to form an endless body. This endless transparent body (8) is rotated in the direction of the arrow in FIG. 1 by a motor (not shown). The transparent body (8) is made of a strong material such as a polyethylene film, and is made of a colored or uncolored transparent body. Further, the transparent body (8) is inserted into the gap between the front glass (1a) and the rear glass (1b), is wound around the upper front roller (3), and is wrapped around the surface of the front glass (1m). reaches the bottom while being in contact with the
It is wound around the lower roller (5) to form an endless body.

Note that the material of the transparent body (8) should not be particularly limited. Further, in the lower part of the window glass (1), the transparent body (8) passes through a detergent liquid tank (9) containing a detergent liquid, and furthermore, a large number of detergent liquid tanks (9) which face each other and are in pressure contact with each other. The sponge rollers 00) 00) are arranged to be interposed between them. Accordingly, the detergent liquid can be kept warm by using engine heat if necessary, and the device should not be specified. Furthermore, the liquid can also be used to wipe away oil films and the like. Moreover, the sponge roller (Ill) (l

8), and the roller (7a) is pressed against it from the front and rear by rubber pads Q+)QQ, etc. This rubber pad Q +) is attached with a spring (not shown) from behind.
It may be pressed by.

Since this embodiment has the above-described configuration, when rainwater adheres to the window glass 0) and the forward view is blocked during rainy weather, the motor is started and the transparent body (8) is rotated. It is. In such a case, the transparent body (8), which has been cleaned by passing through the lower detergent liquid tank (9) and the sponge roller Qo) Qo)...
It rises through the gap between the front glass (Ib) and reaches the lower device while sliding on the surface of the front glass (1) via the upper roller (3).
Rainwater and other sewage adhere to the surface of the transparent body (8) that passes through the surface, but this portion is immediately transferred to the device below by the operation of the motor. When passing through the detergent liquid tank (9), dirty water or oil film etc. are washed away, and the surface of the transparent body (8) is further cleaned by sponge rollers Qo)Qo)... and water droplets etc. is removed. Therefore, the cleaned transparent body (8) enters the gap between the front glass (11) and the rear glass (1b) and repeats the above operation.

In this way, the window glass (1) does not use anything like a conventional wiper, so it does not obstruct the forward view, and the window glass (1) can always be seen through in a transparent state.
The rotation speed of the transparent body (8) can be adjusted as appropriate depending on the degree of adhesion of rainwater, etc.

[Effects of the Invention] As detailed in the above-mentioned embodiment, the present invention is a window glass of a ship, an automobile, or the like, and when looking through the window glass, there is no obstacle to the forward view. .

That is, in conventional automobile wipers that wipe the window glass surface with a rotating action, the action of the wiper obstructs visibility, but this defect is eliminated and the window glass surface is wiped away. Dirty leftover parts caused by cleaning only the area within the rotation trajectory of the wiper are almost eliminated.

Furthermore, the transparent object that moves while sliding on the surface of the front glass is cleaned in a detergent tank in the lower unit, and then moisture is removed by a sponge roller and transferred to the upper part, where it is passed between the front glass and the rear glass. and reaches the surface of the front glass, so when looking through the front of the window glass from behind the rear glass, the state of movement of the transparent body is hardly discernible; You can see through it.

Furthermore, even if the front view is blocked by frost or the like in winter, the frost can be easily washed away by rotating the transparent body, and a sufficient field of view can be maintained. Furthermore, since the front glass of the window glass of the present invention is covered with the transparent body, even if there is a collision or the like, the front glass will not be scattered around.

Note that this invention can be modified in various ways without departing from the spirit of the invention, and it goes without saying that this invention extends to such modifications.
