Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a support for supporting a shower head used in a washbasin, a hair washer, etc. so that it can be taken in and out.

[Conventional technology]

2. Description of the Related Art Conventionally, hair washers installed in barber shops, beauty salons, etc. have generally had a shower head attached to the hair washing container so that it can be taken in and out.

In such a hair washer, in order to support the shower head, a cylindrical support 52 is fixed to a hose insertion hole 51 in a wall surface 50 of the hair washing container, as shown in FIG. This support 52 has an internal structure in which the lower end portion of the shower head can be taken in and out, and a hose connected to a water supply/hot water source can be inserted thereinto.

[Problem that the invention attempts to solve]

Incidentally, the support 52 is generally fixed to the wall 50 of the hair washer by forming a flange 53 on the support 52 and using screws 54 inserted through the flange 53 from the back side of the wall 50.

However, once the support 52 is fixed to the hair washer with the screws 54, it is necessary to remove it by entering the lower part of the hair washer.
Therefore, there is a problem in that the task of replacing the support 52 becomes complicated after the hair washer is installed.

Further, since the support 52 is fixed by the screw 54, the attitude of the support 52 with respect to the wall surface 50 is determined by the position of the screw 54. Therefore,
In order to fix the hair washer in a predetermined posture with respect to the wall surface 50, it is necessary to accurately set the screw hole positions in the wall surface 50, and the manufacturing precision of the hair washer must be increased.

The present invention was devised in view of these problems, and it not only simplifies the work of attaching and detaching the shower head to a hair washer or washbasin, but also allows the support to be accurately fixed in a predetermined position. The purpose is to do so.

[Means for solving problems]

In order to achieve the above-mentioned purpose, the present invention includes a cylindrical fixing bush that is fixed by inserting it through a mounting hole made in the wall of the installation surface, and a support body that has a seat for the shower head formed on the inner periphery. The present invention is characterized in that a gasket is disposed between the fixing bush and the support main body, and is threadedly connected to the surface side of the wall, and receives the fastening force caused by the screw engagement between the fixation bush and the support main body in the axial direction. .

〔Example〕

Hereinafter, the present invention will be specifically described based on embodiments shown in the drawings.

FIG. 1 is a vertical cross-sectional view of essential parts of a shower head support structure according to the present invention, and FIG. 2 is an exploded perspective view.

In the figure, a support 1 supports a shower head A together with a hose B such that it can be inserted into and taken out from a mounting hole 3 formed in a wall 2 of a hair washer or wash basin.

The support 1 includes a fixing bush 4 inserted through the mounting hole 3, a hose guide 5 connected to the fixing bush 4 on the front side of the wall 2, a support main body 6, and an integral part on the back side of the wall 2. The main element is a nut 7.

The fixing bush 4 is fixed in the mounting hole 3 by seating the stepped portion 10 on the outer periphery on the wall 2 through the packing 11, screwing the male screw 12 at the lower end into the nut 7, and interposing the packing 13. . Drain holes 14 are provided at two positions in the radial direction above the stepped portion 10 of the fixing bush 4. As shown in Fig. 3, the male screw 12 at the lower end is threaded on the arcuate portion of the oval peripheral wall, and the opening shape of the mounting hole 3 is such that the oval male screw 12 is inserted through the opening. Make it as elliptical as possible. The relationship between the shapes of the male screw 12 and the mounting hole 3 allows the drain hole 14 to be positioned in the vertical direction as shown in FIG.

The hose guide 5 has a male screw 16 formed on its outer circumferential surface to be screwed into a female screw 15 on the inner circumference of the upper end of the fixing bush 4, and has a drain hole 17 and a notch 18 for draining water at the upper and lower ends of the circumferential wall. They are each located at four positions in the circumferential direction. The hose guide 5 is connected to the fixing bushing 4 with a drainage gasket 19 interposed at its lower end, and has a drainage hole 1 as shown in FIG.
7 and notches 18 that are radially opposed to each other and are fixed in a state aligned with the drain hole 14 of the fixing bush 4.

In addition, as shown in the cross-sectional view of FIG. 4, the draining gasket 19 includes an outer peripheral portion 20 held between the fixing bush 4 and the hose guide 5, and a seal portion 21 with a circular cross section that comes into contact with the peripheral surface of the hose B. The thin wall portion 22 is integrated between the two. In this manner, by providing the thin wall portion 22, elastic deformation when the hose B moves is made quick, and the hose B can be smoothly taken in and out without chattering or the like.

Further, the upper end opening portion of the hose guide 5 and the lower end opening 33 of the bush 4 act as a guide when the hose B moves. Therefore, various structures can be adopted to make the movement of the hose B smooth. For example, by arranging coil springs in the circumferential direction on the inner periphery of the upper end opening of the hose guide 5 and the lower end opening 33 of the bush 4, or by attaching a roller to support the lower surface side of the hose B, the hose B can be smoothly moved. This allows for easy movement. In addition to such a mechanical structure, a structure in which the inner periphery of the upper end opening is shaped like a brush to allow the hose B to move easily can also be adopted.

The support main body 6 is a cylindrical body with a substantially elliptical cross section, and the upper end is provided with two positioning notches 25 that function for positioning the shower head A, and the lower end is provided with positioning notches 25 for discharging water toward the bowl side of the hair washer. A drainage notch 26 is formed. Furthermore, this support main body 6
On the inner periphery of the shower head A, there is a stepped portion 28 for inserting the packing 30 between the seat 27 of the shower head A and the upper end of the fixing bush 4, and a female screw for screwing into the male screw 31 of the fixing bush 4. A screw 29 is formed respectively.

The procedure for attaching the support 1 made up of such elements is as follows.

First, a draining gasket 19 is interposed between the fixing bush 4 and the hose guide 5, and they are integrated with each other by a female screw 15 and a male screw 16, respectively. Next, by positioning the packing 11 on the lower surface of the stepped portion 10 of the fixing bush 4 and inserting it into the mounting hole 3, attaching the packing 13 and screwing the nut 7 onto the male screw 12, the fixing bush 4 is installed. Fix the bush 4 to the wall 2. When installing this fixing bush 4, as shown in FIG. It is necessary to connect the fixing bush 4 and the hose guide 5 in such a manner.

Next, bring the support main body 6 from above and connect the female screw 29 at the lower end to the male screw 3 of the fixing bush 4.
Connect by screwing into 1. In this connection work, a gasket 30 is placed on the lower surface of the stepped portion 28, and the gasket 30 is pressed between the upper end surfaces of the fixing bushes 4. Note that 32 is a slip washer.

Here, the support main body 6 is fixed so that the positioning notch 25 and the drainage notch 26 of the shower head A provided at its upper and lower ends are oriented in a predetermined direction. That is, when the lower end portion of the shower head A is inserted and held in the support 1, the positioning notch 25 is set so that the shower head A faces the front of the hair washer, and the drainage notch 26 is set so that the water drains out. It is necessary to position it so that it is located on the lower end side suitable for. Note that a protrusion a that fits into a positioning notch 25 is formed on the outer periphery of the lower end of the shower head A, and as shown in FIG. At some point, shower head A
The position is to face the front of the hair washer. At this time, the drainage notches 26 are also located at the upper and lower ends in the cross section including the axis of the support main body 6, and water can be drained from the drainage notches 26 on the lower end side.

As described above, the fixing position of the support main body 6 needs to be in an appropriate posture for supporting the shower head A and draining water, and this operation is performed by utilizing the elastic deformation of the packing 30.

That is, when the support main body 6 is fastened to the fixing bush 4, the gasket 30 is gradually compressed and deformed, and due to this compressive deformation, a fastening force is exerted mutually between the support main body 6 and the fixation bush 4. do.
Therefore, the thickness of the packing 30 and the male screw 31
By adjusting the thread pitch of the female screw 29 appropriately, the amount of rotation can be set so that the support main body 6 is in the required position, and it can be fixed in the state shown in FIG. 1. In addition, the positioning notch 25 and the drainage notch 26
are provided at two positions in the radial direction, so they can be connected without excessive or insufficient tightening force.

For the support 1 fixed in the above manner, the first
As shown in the figure, once the shower head A to which the hose B is connected is set, the shower head A can be freely pulled out and used. In addition, the drops that flow through hose B after use should be removed from draining gasket 1.
It is wiped away by 9. Then, these drops are discharged from the notch 18 of the hose guide 5 and the drain hole 14 of the fixing bush 4, and are further discharged from the ball of the hair washer or washbasin through the gap between the drainage notch 26 of the support body 6 and the wall 2. Drainage is carried out in the direction. Furthermore, even if water enters from the upper end of the support main body 6, the water drain hole 17
The water then flows into the hose guide 5, and thereafter is drained onto the wall 2 in the same manner as described above. In this way, by providing the draining gasket 19, when the hose B is stored after use, drops adhering to the hose B and water entering from the outside will not flow into the back side of the wall 2.

Furthermore, the support main body 6 can be easily removed by working from the surface side of the wall 2, and can be prevented from entering the cabinet of the hair washer or washbasin.

Furthermore, since the posture of the support main body 6 can be optimally set by using the packing 30, it is less susceptible to the effects of poor screw hole positioning, etc., compared to the conventional screw fastening structure that penetrates the wall 2. It can be installed without any problems. In particular, considering that in a ceramic hair washer, there is a large error in dimensional accuracy such as drilling, the structure that allows tightening with the gasket 30 is extremely effective.

[Effect of idea]

As explained above, in the shower head support structure of the present invention, the support main body for supporting the shower head is detachable from the installation surface side. Therefore, there is no need to work under the hair washer, washbasin, etc., and parts can be easily replaced. Furthermore, since the connection between the support body and the fixing bushings utilizes the compressive deformation of the gaskets that are compressed by these members, the posture of the support body can be easily set to a predetermined position. . Therefore, compared to the conventional screw fastening structure, the support can be fixed at a predetermined position and in a desired posture without being affected by manufacturing errors of the hair washer or washbasin.
