Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a brush for a car wash which can be effectively used particularly when cleaning the body of an automobile.

<Prior art> As a brush for washing a car, for example, Japanese Utility Model Application No. 58-681
As described in Japanese Patent No. 29, there is known a configuration in which a brush is provided at the tip of an extendable handle, and a water injection port is provided on the back or inside of the brush.

<Problem to be Solved by the Invention> However, the brush for car washing having the above-described configuration is difficult to use because the use mode at the time of car washing is one side where the brush is provided, and the car cannot be washed quickly and effectively. Further, if the brush is damaged, it cannot be used, and cannot be used when the outer surface is relatively strongly rubbed with a brush and washed as in a metallic painted car.

<Means for Solving the Problems> The present invention has been proposed in view of the above. An extendable water guide pipe is extended to a cylindrical holding portion, and a hollow frame-shaped head portion is provided at the tip of the water guide pipe. The head part above has a water outflow hole almost all around except the tip head,
Provided is a car wash brush provided with a coating piece that covers a part of an outer surface of an outflow hole to reduce an opening area of the outflow hole and has flexibility in a water outflow path, and forms a brush portion on the outer surface. It is.

<Example> Hereinafter, the present invention will be described in detail based on an example of the drawings.

In the brush 1 for car washing of the present invention, an extendable water guide pipe 3 is extended at the tip of a cylindrical grip portion 2, and a head portion 4 is provided at the tip of the grip portion 2. This is a configuration in which a water outflow hole 5 is opened all around and a brush portion 6 is formed on the outer surface. The details of the outlet hole 5 will be described later with reference to FIG. 3, which is an enlarged sectional view of a main part of the head unit 4.

The grip portion 2 has a connection port 7 for connecting a water hose a at a rear end, and the water guide pipe 3 integrally extends at a front end.

The water pipe 3 is composed of a first water pipe 8 extending integrally from the grip portion 2 and a second water pipe 9 that can be extended and contracted with respect to the first water pipe 8. At the tip of the first water guide pipe 8, a reduced diameter portion
10 and a trumpet-shaped enlarged diameter portion 11 that increases in diameter toward the open end portion continuously from the reduced diameter portion 10.

On the other hand, the second water pipe 9 is a reduced diameter portion of the first water pipe 8.
A pipe member having an outer diameter enough to be inserted through the pipe 10 and having a rear end located inside the first water guide pipe 8, which is joined to the inner surface of the reduced diameter portion 10 and slidably contacts the inner face of the first water guide pipe 8. It has a diameter portion 12, and a nozzle portion 13 which is thinner than the second water guide pipe 9 and has an open end extends at the end.

The head portion 4 has a hollow frame shape, and has a reduced-diameter opening portion 14 fitted at the base end of the outer surface of the nozzle portion 13 and fixed with an adhesive or the like. The outer diameter portion 15 that is continuous with the outer diameter portion is made to match the inner surface shape of the diameter expansion portion 11 described above. As described above, a water outflow hole 5 is formed on almost the entire surface of the head portion 4, and a brush portion 6 formed by densely implanting relatively soft hair is formed on almost the entire outer surface. However, the outflow hole 5 is not formed in the head 16 of the head 4.

It is desirable that the bristle of the brush portion 6 is soft enough to hang down by its own weight when it is horizontal.

The brush 1 for car washing according to the present invention has the above-described configuration, and has the enlarged diameter portion 12 of the second water guide pipe 9 movably positioned inside the first water guide pipe 8 and the nozzle portion of the second water guide pipe 9.
When the reduced diameter mouth portion 14 of the head portion 4 is fitted to the 13 base end and fixed with an adhesive or the like, the second water pipe 9 can move with respect to the first water pipe 8 so that the water pipe 3 can expand and contract. so,
Further, the water injection port at the tip of the nozzle portion 13 is located in the middle of the head portion 4. In the extended state of the water guide pipe 3, as shown in FIG. 1, the enlarged diameter portion 12 of the second water guide pipe 9 is in a crimped state on the inner surface of the reduced diameter portion 10 of the first water guide pipe 8. There is no possibility of leaking even if water is passed through the inside of 3. In addition, even when the water pipe 3 is in a contracted state, the enlarged diameter portion 12 of the second water pipe 9 is pressed against the inner surface of the first water pipe 8 as shown in FIG.
15 is pressed against the inner surface of the enlarged diameter portion 11 of the second water pipe 9, so that even if water passes through the inner surface of the water pipe 3, there is no leakage.

In order to use the car wash brush 1 formed in this manner, a water hose a is fitted to the connection port 7 in a watertight manner, and the second water pipe 9 is moved to an appropriate position with respect to the first water pipe 8. The length of the water guide pipe 3 is adjusted, and water is supplied from the water hose a to the inside of the head part 4 via the grip part 2 and the water guide pipe 3. As a result, the jet pressure of the water supplied to the inside of the head portion 4 is reduced, and the pressure is reduced due to the collision of water with the inner surface of the head portion 16 of the head portion 4 in particular.
This is the extent to which water flows out of the outflow hole 5 located on the lower side. Therefore, when the lower side of the head portion 4 is rubbed against the vehicle body of the automobile, the vehicle body can be washed with the water flowing out of the outflow holes 5, and it is not necessary to consider the directionality of the head portion 4 when cleaning the automobile. . In addition, since water is not sprayed from the entire circumference of the head unit 4, the water does not scatter around.

When the head 16 of the head 4 is formed of rubber or a flexible synthetic resin, the nozzle 16 of the second water pipe 9 can be used.
The pressure of the water supplied from 13 to the inside of the head unit 4 can be further reduced, and the water is not sprayed from the entire peripheral surface of the head unit 4.

In addition, each outflow hole 5 opened in the above-mentioned head part 4 has:
As shown in FIG. 3, a covering piece 5 'which covers a part of the outer surface to reduce the area of the opening of the outflow hole and provides flexibility in the outflow path of water is provided. This coating piece 5 ′ makes it difficult for water supplied into the head portion 4 to flow out. Therefore, when the head portion 4 is vertically washed, the water flows out only from the lower side of the head portion 4 due to the gravity of the water, and the water does not jet to the upper side of the head portion 4 when the vehicle body is washed.

Although the present invention has been described based on the embodiment of the drawings, the present invention is not limited to the above-described embodiment, and can be implemented in any manner unless the configuration described in the claims for utility model registration is changed. be able to.

<Effects of the Invention> In short, the present invention extends a water guide pipe that can be extended and contracted to a cylindrical holding portion, and provides a hollow frame-shaped head portion at the tip of the above-described water guide pipe. A water outflow hole is set up almost all around except for the outer surface of the outflow hole to reduce the opening area of the outflow hole and provide a coating piece that forms flexibility in the outflow path of the water. Since the brush portion is formed, there is no trouble in cleaning the vehicle body while selecting the direction of the brush portion, and water is not sprayed or scattered upward or to the side during the cleaning, so that the device is easy to use. In addition, if the water drips from the head part, the brush part can be strongly rubbed against the vehicle body for cleaning, and even if a part of the brush is damaged, it can be used in another part, so that it can be used for a long time. In addition, it is possible to provide a car wash brush which is easy to use and has a high use value.
