Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is mounted on a top plate of a bathroom vanity, a hair wash basin, a bathroom unit, etc., and enables the height and direction of a shower head, a spout of a spout pipe, etc. to be adjusted, and a shower head. The present invention relates to a water discharge stand used to support the above.

[0002]

2. Description of the Related Art As this water discharge stand, there is, for example, "Height adjustment device for shower head for wash basin" proposed in Japanese Utility Model Publication No. 3-40940. As shown in FIG. 10, this device "coaxially connects the base cylinder 1 and the tightening cylinder 7 attached to the top plate G of the washbasin, and at the same time, the base cylinder 1 and the tightening cylinder 7 are connected to each other. The movable cylindrical body 2 having the support pipe portion 16 and the through hole 14 communicating with the inner cavity of the support pipe portion 16 in the common insertion holes 3 and 3a provided in 7 is vertically slidable and can be positioned in height. A tension spring 1 which is supported and annularly formed in an annular groove 11 provided in the tightening portion 10 of the tightening cylinder body 7.
2 is wound, and the hose 13 connected to the shower head and the shower head 200 is inserted into the through hole 14 so that the hose 13 can be freely extracted. The height of the support tube can be freely adjusted by moving it up and down with one hand. It has the advantage that it can be performed.

However, in such an adjusting device,
The fact that the height can be freely adjusted with one hand has a problem that when shower water is sprayed from the shower stand, the shower nozzle is rotated by the reaction force of the momentum of the water. That is, this type of shower nozzle is designed so that the water spray direction can be performed not only from directly below but also from the side by rotating the shower nozzle with respect to the support tube portion. Means that the force to rotate in the lateral direction will be obtained by water sprinkling, and the water sprinkling will be done in an undesired direction.

If the shower nozzle is not easily rotated against the reaction force due to such water sprinkling, then the height adjustment in the vertical direction cannot be performed with one hand. In that case, it is considered that the rotation due to the reaction force can be prevented by forming the supporting tube portion or the like into a polygonal shape, or forming a groove or a convex shape in the longitudinal direction even if it is a circular tube. This time, since the support tube has an irregular cross section that is not circular, there arises a problem that it is difficult to seal. In other words, this type of shower head is attached to the top plate of a bathroom vanity unit or bathroom unit, and a seal must be provided to prevent water from leaking from the shower head to the bottom of the top plate. However, if the portion to be sealed has an irregular cross section other than a circular shape, it cannot be easily sealed.

In other words, with respect to the shower stand for attaching the shower head to the top plate of the vanity or the like so that the shower head can freely move in and out, it is necessary to simultaneously solve the following points. Support the shower head firmly to the top plate while freely passing the flexible pipe (pipe for passing hot and cold water) connected to the shower head. The height and direction of the shower head can be easily adjusted. Depending on the reaction force when sprinkling water, prevent the shower head from rotating so that its position does not change. Make sure to seal it so that water does not flow under the top plate.

The above can also be said for a stand that supports the water discharge port of the water discharge pipe so that its position and direction can be freely changed. That is, even when the water outlet of the water discharge pipe is applied instead of the shower head, the above points 1 to 3 must be solved for the water outlet.

The present inventors have described a shower stand of this kind and a stand for supporting the position of the water discharge pipe (in the present invention, these are collectively referred to as a water discharge stand).
The present invention has been completed as a result of various studies on how to satisfy the above items (1) to (3) at the same time.

[0008]

SUMMARY OF THE INVENTION The present invention has been made based on the above-mentioned background, and an object to be solved is to make the function necessary as a water discharge stand sufficient. .

That is, first of all, the object of the invention according to claim 1 is that the height and direction of the shower head and the spout can be freely adjusted, and the shower head and the spout are not affected by the reaction force at the time of sprinkling. Another object of the present invention is to provide a water discharge stand that can be made into a new one and can easily seal the underside of a top plate.

The object of the invention according to claim 2 is to achieve the same object as that of the invention according to claim 1 and yet to sufficiently counter the reaction force due to water sprinkling and to provide a shower head or a spout.

Means for Solving the Problems In order to solve the above problems, first, means adopted by the invention according to claim 1 will be described with reference numerals used in the following embodiments.
"The stand base 10 that supports the shower head 200 and the like connected to the flexible tube 210 at its tip, the joint pipe 20 that is integrated with the other end of the stand base 10, and the joint pipe 20 that is detachable While supporting rotatably,
In a water discharge stand 100 including a holder 30 attached to a top plate 220 such as a vanity, the water is stored in a storage portion 31 formed on the tip side of the holder 30 and is elastically engaged with the holder 30. A stopper ring 40 which stops, and a winding spring which is interposed between the stopper ring 40 and the joint pipe 20 and whose both ends 52 and 52 are wound around the outer periphery of the joint pipe 20 in different directions. 5
0, an engaging portion 51 formed on a part of the winding spring 50 to engage with the stopper ring 40, and a seal 61 attached to the tip end portion of the holder 30 for the joint pipe 20. The water discharge stand 100 ″ includes a seal member 60.

That is, the water discharge stand 100 is
Taking a case where the shower head 200 is to be supported by this, as shown in FIG. 1, the shower head 200 is attached to a top plate 220 such as a vanity, and the tip of the stand base 10 is attached to the shower head 200. And the flexible tube 2 that is connected to the shower head 200.
10 is stored in the shaft center so that it can be freely moved in and out.
As shown in FIGS. 1 and 2, the water discharge stand 100 mainly has a stand base 10 for supporting the shower head 200 connected to the flexible tube 210 at its tip.
And a joint pipe 20 integrated with the other end of the stand base 10, and a holder for supporting the joint pipe 20 in a freely detachable and rotatable manner and attached to a top plate 220 such as a vanity table. The flexible tube 210 is housed so that it can be freely inserted and removed through the respective axial centers.

Incidentally, in this water discharge stand 100, as shown in FIGS.
A mounting portion 11 is formed so as to project at the tip of the mounting portion 1.
By inserting the shower head 200 into the shower head 1, the shower head 200 is supported as shown in FIG. In particular, in the stand base 10 of the embodiment, the serrations in the axial direction are formed on the surface of the mounting portion 11 of the stand base 10 so that the shower head 200 can be supported at different angles. In other words, in the water discharge stand 100, the height and angle of the shower head 200 supported thereby can be adjusted as shown in FIG.
As a matter of course, the shower head 200 can spray hot water in an oblique direction other than directly below, as well as in the range shown in FIG. Needless to say, the other end of the flexible tube 210 to which hot water is supplied is connected to the hot and cold water mixing faucet 230 as shown in FIG.

Here, the relationship between the joint pipe 20 and the holder 30 in the water discharge stand 100 when they are left as they are without any operation will be described.
It is as follows. Since the shower head 200 is supported by the mounting portion 11 with respect to the stand base 10, its gravity is applied to the joint pipe 20 side through the stand base 10, but the joint pipe 20 is not attached to the holder 3.
Since it is held as follows with respect to 0, it cannot be easily lowered by the gravity of the shower head 200 or the like.

That is, this joint pipe 20 is provided in the holder 3
Although it is simply inserted through its axis with respect to 0, since the outer diameter and the inner diameter of the holder 30 are very close to each other, a certain amount of frictional force against gravity is exerted between them. Occurs. Also, at the lower end of the holder 30,
As shown in FIG. 3, an engaging protrusion 37 having an inner diameter slightly smaller than the outer diameter of the joint pipe 20 is integrally formed, and the engaging protrusion 37 constitutes the lower end of the holder 30. The elastic arm 36 is integrally formed. Of course, each elastic arm 36
Is formed by forming an axial cut 36a in the lower end of the holder 30 so that the holder 30 itself has literal elasticity. Furthermore, a seal 61 that causes a frictional force against the joint pipe 20 of the seal member 60 that is screwed to the tip of the holder 30 is interposed.

From the above, with respect to the joint pipe 20 that is simply inserted into the holder 30, the top plate 22
Since various frictional forces are generated on the holder 30 side fixed to the 0 side, even if gravity of the shower head 200 or the like is applied to the joint pipe 20, the joint pipe 20 cannot easily move. is there. Of course, the frictional force generated in the joint pipe 20 cannot resist the force when the joint pipe 20 is moved up and down by hand, even if it resists gravity. Vertical movement is easy.

As shown in FIG. 3, a plurality of annular positioning grooves 22 are formed on the outer circumference of the joint pipe 20, and the elastic arms 36 on the holder 30 side are formed in the positioning grooves 22. By engaging the engaging projections 37 formed in the above, the joint pipe 20 is positioned with respect to the holder 30 to some extent. That is, the joint pipe 2
The positioning of 0 with respect to the holder 30 is performed by the positioning groove 22 on the side of the joint pipe 20 and the engagement ridge 37 on the side of the holder 30, which allows the joint pipe 20 to move up and down with a certain degree of moderation. It has become so. Of course, since each positioning groove 22 engages with the engaging projection 37 on the holder 30 side, it is not a literal groove, but an annular projection formed integrally on the outer periphery of the joint pipe 20. May be

In the water discharge stand 100, as shown in FIG. 9, the joint pipe 20 integrated with the stand base 10 is moved in and out of the holder 30 fixed to the top plate 220. The height and the angle of the shower head 200 supported by the stand base 10 are adjusted by moving or the like. The operation in that case will be described in relation to each component of the present invention. , As follows.

First, the angle of the stand base 10, that is, the top plate 2 of the shower head 200 supported by the angle.
When adjusting the horizontal angle with respect to 20,
In order to do this, the tip of the shower head 200 or the stand base 10 is touched, and the stand base 10 and the joint pipe 20 integral therewith are rotated as shown by the arrow in FIG. is there.

At the portion of the joint pipe 20 inside the holder 30, as shown in FIG. 4, a winding spring 50 which is also shown in FIG. 7 is literally wound, and each end portion 52 thereof is
For example, as shown in FIG. 8A, it is in contact with the surface of the joint pipe 20. Therefore, when the joint pipe 20 is rotated, one end 52 of the winding spring 50 is further caught by the joint pipe 20, and the winding spring 50 and the joint pipe 20 are integrated. Become. However, the winding spring 50 has an engaging portion 51, which engages with the engaging portion 43 of the stopper ring 40 housed in the housing portion 31 of the holder 30. Therefore, the winding spring 50 and the stopper ring 40 tend to be rotated by the rotation of the joint pipe 20.

The stopper ring 40 has a stopper 41 (a metal ball in the example shown in FIG. 4) provided on a part thereof.
Is elastically engaged with any one of the recesses 32 on the holder 30 side by the spring 42,
The reaction force generated by the water spray from the shower head 200 does not rotate with respect to the holder 30, but in this case, the joint pipe 20 is rotated by hand, that is, the reaction force generated by the water spray from the shower head 200 does not occur. Since it is about to be rotated by a force greater than the force, the stopper ring 40
The holder 30 against the biasing force of the spring 42.
It will be rotated in the storage part 31 of the. In the holder 30 of the embodiment, since each recess 32 is formed in a large number on the circumference as shown in FIG.
As the stopper ring 40 rotates together with the joint pipe 20, the stopper 41 elastically engages with each recess 32. Therefore, the joint pipe 20 is rotated with a sense of moderation, which is convenient for use.

In other words, since the joint pipe 20 is a cylinder, it should be able to freely rotate within the holder 30, but the stopper 41 on the stopper ring 40 side should be able to rotate freely.
Is elastically engaged in any one of the recesses 32 on the holder 30 side by the urging force of the spring 42, so that a certain amount of force (specifically, the shower head 20
By applying a force larger than the reaction force due to water sprinkling from 0), it is rotated with a feeling of moderation. In other words, it means that the joint pipe 20 cannot be rotated with a reaction force due to water sprinkling from the shower head 200. Stand base 10 and shower head 200 supported thereby
It does not rotate in an unexpected direction.

This time, the height of the stand base 10, that is, the top plate 2 of the shower head 200 supported by the stand base 10.
This is a case of adjusting the height with respect to 20. In this case, the stand base 10 or the joint pipe 20 may be held in the hand and moved up and down. In this case, the holder 3
Winding spring 50 housed in the housing 31 of 0
Has no effect, that is, the joint pipe 20 and the holder 30, and the joint pipe 20, the seal member 60 and the seal 61.
Since only the frictional force between and acts on the joint pipe 20, the joint pipe 20 can be easily moved up and down.

In the water discharge stand 100 of the embodiment described in detail below, since the cushioning material 12 is attached to the lower end of the stand base 10, the operation is rapid when it is pushed down to the lowermost end of the joint pipe 20. Even in this case, since the cushioning material 12 comes into contact with the seal 61, not only abnormal noise does not occur but also the impact at that time is softened to protect the stand base 10 and the seal 61. On the other hand, since the end stopper 21 having the O-ring 21a is also formed at the lower end of the joint pipe 20, the end stopper 2
Since the joint pipe 20 is prevented from coming off from the holder 30 by 1 and the O-ring 21a serves as a cushioning material for the lower end on the holder 30 side, an abnormal noise is generated when the joint pipe 20 is vigorously pulled out. Not only is it suppressed, but the lower end of the holder 30 and the end stopper 21 are protected.

Of course, in the water discharge stand 100, since the seal 61 of the seal member 60 attached to the upper end of the holder 30 is always interposed between the joint pipe 20 and the holder 30 described above, the joint pipe is Even if the water transmitted through 20 tries to enter under the top plate 220, the invasion thereof is blocked by the seal 61 on the seal member 60 side. This prevention is performed regardless of the position of the joint pipe 20 with respect to the holder 30, and is always stable. Since such a seal 61 can form the joint pipe 20 and the holder 30 forming the water discharge stand 100 into a cylindrical shape, it can be formed with a simple structure, specifically, an annular shape. Therefore, the sealing effect can be surely achieved.

In order to solve the above-mentioned problems, the means adopted by the invention according to claim 2 is that, in the water discharge stand 100 according to claim 1, the stopper ring 40 is elastically locked to the holder 30. 40 or a plurality of recesses 32 formed on a surface facing the holder 30 or the stopper ring 40 and having a stopper 41 that is attached to the holder 30 side so as to be freely retractable and is elastically supported by a spring 42. This is done by engaging with.

That is, in the water discharge stand 100 according to the second aspect of the present invention, the spring 42 and the stopper 41 are housed in the housing groove 41a formed in the stopper ring 40, for example, and the housing portion 31 of the holder 30 is housed. A plurality of recesses 32 are formed on the circumference, and one stopper 41 on the stopper ring 40 side is elastically engaged with any one recess 32 on the holder 30 side. Is. As a result, the turning force of the joint pipe 20 due to the reaction force due to water sprinkling in the shower head 200 can be resisted, and the joint pipe 20 can be manually rotated with a sense of moderation.

In order to solve the above-mentioned problems, the means adopted by the invention according to claim 3 is as follows.
In the water discharge stand 100 according to the first embodiment, the winding spring 50 is composed of the upper winding spring 50a and the lower winding spring 50b. With this configuration, for example, the one shown in FIG. 7 is turned upside down, and if it is interposed between the joint pipe 20 and the stopper ring 40 as shown in FIG. 4, it is necessary. The water spring stand 50 can be used as the winding spring 50.
Not only can the whole 0 be manufactured easily, but also the assembling work can be easily carried out.

The operation of each of the above-described inventions has been described mainly in the case where the water discharge stand 100 shown in the following embodiments is one in which the flexible tube 210 is inserted into the axial center thereof. The flexible tube 210 is the water discharge stand 1
The same applies to the case of being arranged outside 00. Further, the above is also applicable to the case where the water discharge stand 100 supports the water discharge port of the water discharge pipe so that its position and direction can be freely changed.

A shower head 200 is connected to the tip of the joint pipe 20. The shower head 200 has an angle (sprinkling water) on the mounting portion 11 formed as a protrusion having axial serration at the tip (left end in FIG. 1) of the stand base 10 that constitutes the water discharge stand 100. (Direction) It can be freely inserted and removed, and water is sprayed when washing hair. As shown in FIG. 1, the other end of the flexible tube 210 is connected to a hot and cold water mixing faucet 230 that is separately attached to the top plate 220 or the like. In the present embodiment, the top plate 220 is used. By the operation lever 231 arranged above, supply to the flexible tube 210 side and temperature adjustment can be performed.

As shown in FIGS. 2 and 3, the water discharge stand 100 according to the present invention has a holder 30 inserted from above a mounting hole formed in the top plate 220 and an axial center hole of the holder 30. And a holder 30 which are inserted from below into the joint pipe 20 to which the stand base 10 is attached at the upper end.
And a seal member 60 attached to the upper end portion of the holder 30, and the holder 30 includes a seal member 34a and a slip plate 34b.
It is fixed to the top plate 220 by the fixing nut 34 via. As shown in FIG. 4, the portion of the holder 30 above the top plate 220 has a diameter larger than that of the mounting hole of the top plate 220.
A retaining portion 31 for accommodating and assembling a stopper ring 40 and a winding spring 50, which will be described later, is formed.

As shown in FIGS. 1 to 3, the stand base 10 is substantially L-shaped, and its axis has a flexible tube similar to the joint tube 20 connected to the lower end thereof. An insertion port is formed to store 210 in a freely accessible manner. Further, at the tip of the stand base 10, a mounting portion 11 having an axial serration is integrally formed so that the rear portion of the shower head 200 to be supported can be inserted and supported at a predetermined angle. I am doing it. That is,
