Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiper for removing water droplets and dirt adhered to a window surface of vehicles such as various vehicles and ships, and more particularly to a dirt such as a windshield of an automobile with a small amount of cleaning liquid. It relates to a wiper that can be removed well.

[0002]

2. Description of the Related Art Conventionally, in order to remove dirt from a windshield of an automobile or the like, a cleaning liquid is sprayed onto a windshield from one or several cleaning liquid injection ports provided on a bonnet.
A wiper that sweeps and wipes the glass surface with a flexible elongated wiper blade such as rubber is often used.

[0003]

However, in the above-mentioned conventional wiper, the cleaning liquid sprayed from the bonnet far from the windshield is applied to only a small portion of the glass, and the high-speed running of the automobile is difficult. The cleaning solution scatters when it is subjected to a medium or strong wind, and it is difficult to spray the cleaning solution over the entire area of the windshield.

The present invention has been made to solve the above-mentioned drawbacks of the conventional wiper. The cleaning liquid can be efficiently supplied to the entire area of the glass, and the cleaning liquid is scattered even during high-speed running or strong wind. It is an object of the present invention to provide a suitable wiper that is unlikely to be damaged. As a result, there is no danger that the cleaning liquid tends to be insufficient even when used for a long period of time, and a sufficient amount of the cleaning liquid is supplied to the entire surface of the glass so that dirt can be reliably removed in a short time. It is.

[0005]

In order to achieve the above object, a wiper according to the present invention is a wiper for removing dirt from a window surface by moving the wiper blade on the window surface. The contact portion is formed with a concave groove for retaining the cleaning liquid supplied from the cleaning liquid supply means.

Further, a passage is formed inside the wiper blade for sending the cleaning liquid supplied from the cleaning liquid supply means into the concave groove.

[0007] The concave groove is formed over the entire length of the window surface contact portion of the wiper blade.

[0008] A passage for sending out the cleaning liquid is provided at a central portion in the longitudinal direction of the wiper blade.

Further, the window surface is a glass surface in vehicles such as various types of vehicles and ships.

[0010]

1, 2 and 3 show an embodiment of a wiper 1 according to the present invention. The wiper 1 moves by contacting a window surface contact portion 3 a at the tip with a surface of a glass 2. Flexible wiper blade 3 and the wiper blade 3
And a wiper arm 4 that rotates left and right around the base end, and a cleaning liquid tank (not shown) inside the hood.
And a flexible cleaning liquid pipe 5 for supplying the cleaning liquid to the wiper blade 3 via a pump as cleaning liquid supply means.

As shown in FIGS. 2 and 3, the wiper blade 3 has a groove 7 for storing the cleaning liquid 6 in a window surface contact portion 3a that contacts the glass 2, and the cleaning liquid 6 is formed in the groove 7. In the central part in the longitudinal direction of the wiper blade 3, a passage 8 consisting of a through hole communicating with the concave groove 7 is provided, and a tip 5 a of the cleaning liquid pipe 5 is inserted above the passage 8. . 9 is a claw for fixing the wiper blade 3 to the wiper arm 4.

Although the groove 7 can be formed at one or a plurality of positions, it is practical to form the groove 7 over the entire length of the window surface contact portion 3a of the wiper blade 3.

A cleaning liquid pipe 5 connected to a cleaning liquid supply means (not shown) is guided from the base end of the wiper arm 4 along the arm or through the arm to the central portion of the wiper blade 3, where the cleaning liquid is supplied. The cleaning liquid 6 is sent out into the concave groove 7 of the wiper blade 3 by pressurizing the cleaning liquid 6. The pressure applied to the cleaning liquid 6 does not need to be as large as that of the conventional cleaning liquid jetting pressure, because the wiper arm 4 reciprocates in an arc shape, so that the wiper blade 3 is moved into the concave groove 7 above the central portion in the longitudinal direction. This is because the cleaning liquid 6 is sent by centrifugal force, and flows naturally downward into the concave groove 7 below the central portion of the wiper blade 3 by its own weight.

FIG. 3 shows a state in which the wiper of the present invention cleans the surface of the glass 2. The window surface contact portion 3 a of the wiper blade 3 holds the cleaning liquid 6 in the concave groove 7 and the right side. The surface of the glass 2 is cleaned while moving in the direction.

FIG. 4 shows another embodiment of the wiper blade of the wiper according to the present invention, in which the concave groove 11 and the outer shape of the wiper blade 10 are more curved than those of the above-described embodiment. . The shape and cross-sectional area of these concave grooves are appropriately set according to the delivery pressure of the cleaning liquid and the angular velocity of the wiper arm, and the delivery pressure of the cleaning liquid also needs to be appropriately set according to the angular velocity of the wiper arm. .

In the wiper of the present invention having such a configuration, since the cleaning liquid flows along the window surface in the concave groove of the wiper blade, the cleaning liquid is used even when the automobile is running at a high speed or in a strong wind. And there is almost no scattering, and sufficient washing can be performed in a short time.

[0017]

As described above in detail, according to the wiper of the present invention, in a wiper for removing dirt on the window surface by moving the wiper blade on the window surface, the wiper blade is disposed on the window contact portion of the wiper blade. By forming a concave groove for retaining the cleaning liquid supplied from the cleaning liquid supply means, it is possible to preferably clean the window surface with which the wiper blade contacts by merely passing a small amount of the cleaning liquid into the concave groove of the wiper blade. The cleaning liquid can be used effectively and efficiently without wasting spray liquid even during high-speed running or under strong wind, and can be cleaned in a short time, so safety in driving of automobiles etc. This is extremely effective in improving the quality of resources and effective utilization of resources.

Further, since a passage for sending the cleaning liquid supplied from the cleaning liquid supply means into the concave groove is formed inside the wiper blade, the cleaning liquid can be surely supplied into the concave groove from the cleaning liquid supply means. Can be.

Further, by forming the concave groove over the entire length of the window surface contact portion of the wiper blade, the window surface can be quickly and efficiently cleaned according to the entire width of the wiper blade.

Further, by providing a passage for the cleaning liquid in the central portion of the wiper blade in the longitudinal direction, the reciprocating motion of the wiper arm in an arc shape allows the wiper blade to be centrifuged into the concave groove above the central portion in the longitudinal direction. The cleaning liquid is sent by force, and flows naturally downward into the concave groove below the central portion of the wiper blade by its own weight, which is extremely efficient.
