[0002]

2. Description of the Related Art In recent years, a wash basin or a sink provided with a shower head connected to a faucet such as hot water using a flexible tube such as a hose has been widely used. In this type of wash basin or the like, a support device that accommodates and supports the base end of the shower head so that it can be freely inserted and removed with the flexible tube inserted is often used. Such a support device includes a housing support portion projecting substantially in a cylindrical shape, and a hollow bearing member mounted and fixed to the housing support portion, and a base end portion of the shower head is housed and supported in the support member. It is common. At that time, the base end of the shower head and the support member are connected by a method such as meshing using serrations or engagement between a slide projection and a slide groove. As a result, the entire shower head is supported by the support member and the pulling member. In many cases, the housing supporting portion is supported in a non-rotatable state.

[0003] On the other hand, it has been generally accepted that (a) screwing, screwing, or the like is used for fixing the bearing member to the accommodating and supporting portion. (B) In recent years, a fitting projection is provided on the bearing member. A method has also been proposed in which a projection is provided and the projection is fitted in a fitting hole provided in the housing support portion (Japanese Patent Application Laid-Open No. Hei 7-197501).

[0004]

However, the methods (a) and (b) have the following disadvantages. That is, if the former (a) screwing, screwing, or the like is used, a step of providing a screw hole, a screw hole, or the like in the housing support portion and the support member is required, or a male screw is screwed into this screw hole. And a step of driving a screw into a screw hole is required. In addition to this, the number of parts increases due to the use of screws and screws, so that the manufacturing cost of the support device is increased, and the manufacturing effort is easily increased. In addition, there is also a problem that stress cracking is likely to occur in a portion around a screw hole, a screw hole, or the like of the housing support portion.

Further, in the former case (a), in addition to screw holes, screw holes, etc., water, hot water, etc. which are connected to the support member from the shower head and the inside of the storage support portion are provided in the storage support portion. It is necessary to provide a drain hole in order to discharge water to the outside. Also, in the case of fitting the fitting projection and the fitting hole of the latter (b), it is necessary to provide a similar drainage hole in the housing support portion in addition to the fitting hole. Become. Therefore, in any case, the number of steps for manufacturing the supporting device is increased and the appearance of the supporting device is often reduced by the amount of providing the water draining hole separately from the hole for fixing the support member. In the latter case (b), it is necessary that the fitting projection provided on the support member and the fitting hole provided on the housing support part be fitted with high accuracy. For this reason, a certain amount of labor is required for forming the fitting protrusions and the fitting holes and for fixing the support member to the housing support portion. Thus, in the conventional shower head support device,
There are various problems due to the method of fixing the bearing member to the housing support.

An object of the present invention is to solve the above-mentioned problems, and an object of the present invention is to provide a shower head supporting device having high manufacturing efficiency and low manufacturing cost.

A drainage clearance through which water can flow or a drainage space through which water can flow is provided, and these function as drainage holes (holes). That is, one engaging through-hole provided in the housing support portion also serves as an engaging hole for fixing the support member and a drain port (hole). Therefore, it is not necessary to separately provide an engagement hole and a drain port (hole) for the accommodation support portion, and the number of manufacturing steps of the supporting device is reduced, and the manufacturing efficiency is improved and the manufacturing cost is reduced. be able to. Further, in this way, the number of holes provided in the accommodation support portion or the like can be minimized, so that the appearance of the support device can be improved.

[0009] Further, even in the point that parts such as screws and screws are unnecessary, the working efficiency can be improved and the manufacturing cost can be reduced. Furthermore, instead of fitting the engaging projections into the engaging through holes, the two are simply engaged with each other, and furthermore, a drainage clearance through which water can flow or a drainage space through which water can flow. Is planned to be provided. Therefore,
The function of the engagement hole and the drainage hole (hole) can be achieved without requiring very high precision in forming the engagement protrusion and the through hole for engagement. This also improves the production efficiency and the production cost. Inexpensive.

In addition, this device uses a predetermined hose S to house the base end K of the shower head H connected to the hot and cold water mixing faucet L so that the hose S can be inserted and removed freely. .

The device includes a device main body 1 and a support member 2. Among these, the apparatus main body 1 is provided with a housing support portion 11 projecting obliquely upward from a basin (not shown).
It has. As shown in FIGS. 2 and 3, the housing support portion 11 has a substantially cylindrical shape. A substantially planar rectangular cutout 11a is provided in the wall below the protruding end. Further, as shown in FIGS. 1 and 2, a drain portion 11 b having a substantially donut shape is attached to a lower portion of the housing support portion 11. Note that a packing made of rubber, resin, or the like can be used as the drainer 11b. However, the hole provided in the center of the drainer 11b needs to be provided in a size that does not hinder the movement of the hose S due to the insertion and removal of the base end K. The drainer is the main unit 1
It is not limited to a separate member, and may be formed integrally with the housing support portion 11. Although not shown, the draining section may be provided with a draining section only at the lower portion of the housing support section 11 such as a donut plate having a substantially semicircular shape, as long as it can substantially completely prevent the water from flowing down.

A substantially planar elliptical engaging through-hole 11c is provided in a lower wall portion of the housing supporting portion 11 on a protruding end side of the draining portion 11b. In addition, this through-hole 11c
And the notch portion 11a are aligned on the same straight line along the axis of the storage support portion 11. The notch 11
“a” is slightly wider than the engagement protrusion 24.

On the other hand, the support member 2 is a hollow article made by integrally molding an elastic material such as resin. This support member 2
As shown in FIGS. 2 and 3, a base portion 21 having an outer shape in which a lower wall portion excluding a front end side of a cylindrical shape is cut out in a substantially planar rectangular shape, and a lower wall portion on a front end side of the base portion 21. A cantilever-shaped extending beam portion 22, a projecting portion 23 projecting downward from a lower wall portion on the front end side of the base portion 21, and an engagement projecting downward from a rear end of the beam portion 22. And a projection 24. The protrusion 23 is provided at a position where the support member 2 can be aligned with the notch 11a when the support member 2 is mounted on the housing support portion 11, and the outer shape of the protrusion 23 is as follows.
The outer shape and the unevenness of the cutout portion 11a are reversed.

The engaging projection 24 is substantially in the shape of a tongue piece, and has a transverse section approximately one-third the size of the engaging through-hole 11c. Then, as shown in FIGS. 4 and 5, when the support member 2 is mounted on the housing support portion 11, the engaging through-hole 1 is provided.
It is aligned with the front side of 1c (the protruding end side of the housing support 11). Specifically, the front outer surface of the engaging projection 24 engages with the front inner surface of the engaging through-hole 11c. An empty portion, that is, a drainage space P through which water can flow is formed between the outer surface behind the engagement protrusion 24 and the inner surface behind the through hole 11c for engagement. The engagement projection 24 and the projection 23
Are also provided on the same straight line along the axis of the support member 2. FIG. 4 is a partial vertical cross-sectional view when the support member 2 is mounted on the housing support portion 11, and FIG. 5 is a partial rear view for explaining the relationship between the engaging protrusion 24 and the engaging through-hole 11c ( (Observed from the direction of arrow X in FIG. 1).

As shown in FIG. 2, the inner wall of the support member 2 is stepped. A groove M that meshes with a serration R provided in front of a base end K of the shower head H is provided in an inner wall portion having a large inner diameter located in front. However, the method of connecting the base end K of the shower head H and the support member 2 is not limited to the engagement using the serrations R and the grooves M. For example, a slide projection provided on the base end K may be engaged with a slide groove provided on the support member 2.

Next, a brief description will be given of a method of attaching the support member 2 to the accommodation support portion 11. First, as shown in FIG.
The rear end of the support member 2 is disposed in front of the projecting end of the housing support 11. At this time, the engagement projection 24c and the projection 23 provided on the support member 2 are located below.
Next, the support member 2 is inserted into the housing support portion 11 while bending the beam-shaped portion 22 toward the inside of the support member 2. At this time, the engaging projection 24 of the support member is inserted into the notch portion 11a, and the support member 2 is inserted straight into the housing support portion 11 as it is. As described above, the through hole 11c and the notch 11
“a” are aligned on the same straight line along the axis of the housing support portion 11, and the notch portion 11a is
Since the width is slightly wider than that, the positioning guide of the circumferential angle of the support member 2 can be easily performed, and the mounting workability of the support member 2 can be improved. Further, when the support member 2 is linearly pushed in, the engagement projection 24 is positioned at a position where the projection 23 starts to be inserted into the notch 11b when the engagement projection 24 exceeds at least the rear end of the notch 11a. And the projection 23, the mounting operation can be performed without the support member 2 being substantially rotated with respect to the apparatus main body 1. Further, when the engagement protrusion 24 reaches the engagement through-hole 11, the beam-shaped portion 22 is restored. Then, the engagement protrusion 24
Are engaged with the through holes 11c for engagement, and this mounting is completed. At this time, a drainage space P that functions as a drain port (hole) is formed behind the engagement protrusion 24.

Next, the operation of the present apparatus will be described. In the present device, one engagement through hole 11 provided in the accommodation support portion 11 is provided.
c serves both as an engagement hole for fixing the support member 2 and a drain port (hole). Therefore, since it is not necessary to provide a plurality of holes separately in the housing support portion 11, the number of manufacturing steps can be reduced,
It is possible to improve the production efficiency and reduce the production cost. In addition, since the number of holes provided in the housing support portion 11 can be minimized, the appearance of the support device can be improved.

Further, as described above, it is possible to easily perform the work of mounting the support member 2 to the housing support portion 11, thereby improving the manufacturing efficiency and reducing the manufacturing cost.
In particular, in this operation, since no screws, screws, or the like are used, the production efficiency can be improved and the production cost can be reduced. It is also excellent in that it does not cause inconveniences such as "stress cracking" as in the case of using screws and screws. Furthermore,
In the present apparatus, the production efficiency is improved and the production cost is reduced even in the point that not very high accuracy is required for forming the engagement projection 24 and the engagement through-hole 11c.

Further, the function of the protrusion 23 and the notch 11a allows the support member 2 to be further fixed to the housing support 11 by the function of the protrusion 23 and the notch 11a.
Be strong. In addition, from the viewpoint that the positioning of the support member 2 and the housing support portion 11 is easy, the improvement of the manufacturing efficiency and the like are achieved. Further, many of the conventional wash basins have a housing support 11.
A tray and the like for storing water and hot water flowing down from the inside of the sink to the inside of the wash basin are arranged inside. However, in the present apparatus, even when water or the like enters the inside of the housing support portion 11, the water is smoothly discharged to the outside of the apparatus through the drainage space P. In addition, the draining portion 11 is provided below the accommodation support portion 11.
Since b is mounted, it is possible to almost completely prevent the water or the like from flowing down into the inside of the wash basin (not shown). Therefore, by using this device, the productivity of the wash basin can be improved,
The structure can be simplified, the manufacturing cost can be reduced, and the like.

In the "supporting device" (JP-A-7-197501) according to the prior art, the inner peripheral surface of the support member (hook) is located closer to the projecting end than the drain hole of the inner peripheral surface. It has been proposed to provide a "projection" for weakening the flowing water flow. This is considered to be intended to reliably guide the water flow to the drain hole. On the other hand, in the present device, the flowing water or the like is filled with two notched spaces provided between the beam-shaped portion 22 of the support member 2 and the base portion 21 (d and e in FIG. 3). To the drainage space P without fail. For example, even if the water passes through the drainage space P, the water draining portion 11b provided behind the space P dams the water or the like flowing down. Therefore, in the present apparatus, it is possible to almost completely prevent water or the like from flowing down into the inside of a washstand (not shown) without dare to provide the “projection” shown in the above-mentioned prior art.

The scope of the invention described in each of the claims is as follows:
The present invention is not limited to the specific embodiments described above. That is, in addition to the above-described embodiment, various modified examples can be exemplified. First, the engaging through-hole 11c
The shape of the engagement projection 24 is not limited to that shown in the above embodiment. For example, as shown in FIG. 6, the hole shape of the through-hole 511c for engagement may be circular, and the shape of the engagement protrusion 524 may be a semi-disc shape. This drawing is a partial back view for explaining the relationship between the engaging protrusion 524 and the engaging through-hole 511c.

In this modification, the shapes of the through-holes for engagement 511c and the engagement projections 524 are simplified, so that the production efficiency of the support device is further improved and the production cost is further reduced. However, the shapes of the engaging through-holes 11c and 511c and the engaging protrusions 24 and 524 are shapes other than those shown in the embodiment and this modification (planar triangular, planar rectangular, etc.).
Can also be selected. Further, as a second modified example,
The apparatus shown in FIGS. 7A and 7B can be exemplified. FIG. 7A is a partial vertical cross-sectional view when the support member 62 is mounted on the housing support portion 611, and FIG.
FIG. 9 is a partial rear view for explaining the relationship between the fourth through hole 4 and an engaging through hole 611c.

In this modification, as shown in FIGS. 7A and 7B, the outer circumference of the engaging projection 624 along the cross section is made substantially equal to the size of the engaging through hole 611c, and In the center of the 624, a through hole 624 penetrating the front and back surfaces
a (P) is provided. When the support member 62 is fixed to the housing support portion 611, the through hole 624a (P)
Becomes the drainage space P. According to this modification, the same effect as that of the embodiment can be obtained. In this modification, it is considered that the engagement protrusion 624 is fitted or pushed into the engagement through-hole 611c. However, since the engagement protrusion 624 has the through-hole 624a (P) and can be relatively easily compressed and deformed, the engagement protrusion 624 and the through-hole 6
The formation of 11c need not be so precise.
Further, as a third modified example, one shown in FIG. 8 can be exemplified. FIG. 8 shows the engagement protrusion 724 and the through hole 711 for engagement.
It is a partial back view for explaining the relationship with c. In this modification, notches 724a are formed on both front and back surfaces of the engagement protrusion 724 instead of the through holes 624a (P) of the second modification.
(P) is provided. And also in this modified example,
Functions similar to those of the second modification are exhibited.

As a fourth modification, FIG.
Examples shown in (b) can be exemplified. 9A is a partial vertical cross-sectional view when the support member 82 is mounted on the housing support portion 811. FIG. 9B illustrates the relationship between the engagement protrusion 824 and the through hole 811c for engagement. FIG.
In this modification, as shown in FIG.
4 is made longer and its lower end 824a is
It protrudes outside of 1. In addition, the engagement protrusion 824
Are engaged with the front and rear ends of the inner surface of the engagement through-hole 811c, and drainage spaces P1 and P2 are formed on both sides of the engagement protrusion 824. In this modification, the water, hot water, etc., which have entered the drainage spaces P1 and P2,
Of the engaging projection 824.
4a, and the liquid is dropped from the lower end 824a. Therefore, according to this modification, the water and the like drawn out from the drainage spaces P1 and P2 cause the outer wall 81 on the lower side of the apparatus main body 1 to be removed.
a can be reliably prevented.

FIG. 10A shows a fifth modification.
Examples shown in (b) can be exemplified. FIG. 10A is a partial vertical cross-sectional view when the support member 92 is mounted on the housing support portion 911, and FIG. 10B illustrates the relationship between the engagement protrusion 924 and the engagement through hole 911c. FIG. In this modification, the cross section of the engagement protrusion 924 is slightly smaller than the engagement through-hole 911c. When fixed to the housing support portion 911c of the support member 92, a gap between the outer surface of the engagement protrusion 924 and the inner surface of the engagement through hole 911c, that is, the drainage clearance Q through which water can flow.
Is caused. In this modified example, the clearance Q functions similarly to each of the drainage spaces. Generally, a gap between the engaging projection and the hole is formed in a range of usually 0.2 to 0.3 millimeters with normal accuracy in a manufacturing process, and water can flow through the gap.
In this case, such a gap generated with normal accuracy in the manufacturing process of the engagement projection and the engagement through hole functions similarly to the drainage space. Therefore, the formation of the engagement projections and the through holes for engagement does not require very high precision, so that the manufacturing efficiency is improved and the manufacturing cost is reduced.

[0028]

As described above, according to the present invention, it is not necessary to separately provide an engagement hole and a drainage hole (hole) in the accommodation support portion, so that the number of manufacturing steps of the support device can be reduced. It is possible to improve the production efficiency and reduce the production cost. Also,
Since the number of holes provided in the housing support portion can be minimized, the appearance of the support device can be improved. Further, since the number of parts can be reduced without using screws, screws, and the like, improvement in work efficiency and reduction in work cost can be achieved. In addition, the production efficiency is improved and the production cost is reduced, since not too high precision is required for forming the engagement projection and the engagement through-hole.
