 An embodiment of a height position adjusting device for a shower head according to the present invention will be described below with reference to the drawings.

Reference numeral 11 in the drawing denotes a top plate such as a sink, a wash basin, and a hair wash basin. As shown in FIG. 2, an attachment socket 14 as an attachment member is fitted into the attachment opening 12 formed in the attachment surface of the top plate 11 or the like, and the attachment socket 14 has a screw cylinder shape. At the same time, the through hole 13 is formed therein. Then, the mounting socket 14 is mounted on the ceiling plate 11 by tightening the nut 17 via the packing 15 arranged on the upper side and the lower side of the top plate 11 and the spring washer 16 arranged immediately below the lower packing 15. It is fixed to the plate 11.

As shown in FIGS. 2 and 8, an annular recess 18 is formed in the upper portion of the mounting socket 14, and a positioning means H for a slide pipe 22, which will be described later, is formed in the annular recess 18. Will be deployed. On the upper part of the mounting socket 14, a mounting base 19 as a mounting member is mounted from above so as to cover the positioning means H and the mounting socket 14. The mounting table 19 has a through hole 19 a communicating with the through hole 13 therein, and is a component of the positioning unit H and a storage unit 19 b for storing the U packing K that contacts the positioning unit H. It is provided with an annular projection 19d that comes into contact with a leaf spring 21 (described later). Further, as clearly shown in FIG. 6, a third protrusion 19c having a partially protruding shape and an annular recess 19e are provided on the upper part of the mount 19, and the O-ring O is provided in the annular recess 19e. It is installed. As shown in FIG. 8, the mounting socket 14 is provided with protrusions 14a at positions every 90 degrees on the outside of the upper part thereof, and on the inner bottom portion of the mounting base 19 is shown in FIG. As described above, the mounting seat plate 19g having the protrusions 19f is installed at every 90 degrees. Therefore, the mounting base 19 is mounted so as to cover the mounting socket 14 and the mounting base 19 is rotated by a predetermined angle with respect to the mounting socket 14 so that the respective projections 19f and the respective projections 14a do not hit each other. Then, each protrusion 19f is hooked on each protrusion 14a. As a result, the mounting base 19 is fixed to the mounting socket 14.

As shown in FIG. 3, the positioning means H includes a pair of support members 20 which are arranged opposite to each other with a slide pipe 22 interposed therebetween, and which are made of, for example, a resin material having good wear resistance, and these support members. A pair of elastic members mounted so as to be hooked on 20 are provided, for example, an arc-shaped leaf spring 21. Each supporting member 20 is provided with a central protrusion 20a for rotation prevention provided so as to fit into a plurality of recesses 18a provided on the same wall of the annular recess 18, and on both sides of this protrusion 20a. The protrusion 20b is formed. Then, by engaging both ends of each leaf spring 21 with each protrusion 20b of the one side support member 20 and each protrusion 20b of the other side support member 20, the respective support members 20 are attracted to each other. The outer peripheral portion of the slide pipe 22 is elastically abutted. In this case, the size of the diameter formed inside these support members 20 is set to be slightly smaller than the diameter of the slide pipe 22, and these support members 20 are arranged relative to the slide pipe 22 as shown in FIG. Since the contact surface is arcuate in cross section, point contact with low frictional resistance is possible. Accordingly, the plurality of support members 20 attracted by the leaf springs 21 are elastically pressed against the outer peripheral portion of the slide pipe 22 to be inserted to support and fix the slide pipe 22, and this support and fixation can be easily performed by an external force. It is designed to be released. In this way, the pair of support members 20 and the pair of leaf springs 21 function as the positioning means H for the slide pipe 22, but the support members 20 and the leaf springs 21 are always configured as a pair as described above. It may not be provided, and the number may be three or more.

Then, the slide pipe 22 described above is movably inserted into the through hole 13 of the mounting socket 14 and the through hole 19a of the mounting base 19, and one end (upper end) of the pipe 22 is a base of the shower head portion S. It is attached to the insert nut N inside the end as follows. That is, the base end portion of the shower head portion S serves as a decorative pipe P that is fixed to the slide pipe 22, and an insert nut N is attached to the inside of the lower end of the decorative pipe P so that it is above the slide pipe 22. The threaded portion formed at the end is screwed onto the insert nut N. Further, the tightening ring 23 is screwed to the threaded portion formed on the outside of the lower end of the decorative pipe P. A shower hose 24, which is a long flexible tube connected to a hot and cold water mixing plug (not shown), passes through the inside of the slide pipe 22 and further extends to the shower head portion S.

As shown in FIG. 1, a nut 26 is fastened to the other end (lower end) of the slide pipe 22 via a packing 25 so that the pipe 22 does not come out of the through hole 13 of the mounting socket 14. Functions as a stopper material. Further, a recess W is formed on the outer periphery of the slide pipe 22, and the support member 20 is fitted into the recess W when the lower end of the mounting socket 14 contacts the nut 26. Therefore, when the nut 26 of the slide pipe 22 comes into contact with the lower end of the mounting socket 14, the shower head portion S is located farthest from the top plate 11. The nut 26 is provided with a partially protruding first locking portion 26a on the outer peripheral portion thereof, and at the lower end of the mounting socket 14 is provided with a partially protruding second locking portion 14b. When the slide pipe 22 rotates, the first locking portion 26a and the second locking portion 14b come into contact with each other at a predetermined angle position. That is, as shown in FIG. 4, the second locking portion 14b is a protrusion formed along a part of the outer periphery of the lower end of the mounting socket 14, and the first locking portion 26a is the second locking portion. The shower head portion S and the slide pipe 22 freely rotate within a range that does not hit the stop portion 14b (a range X in the drawing). As a result, the first locking portion 26a engages with the second locking portion 14b provided at the lower end of the mounting member 14 in a state where the shower head portion S is farthest from the top plate 11, The turning angle of the shower head S is restricted. Therefore, the swinging angle of the shower head S can be regulated within a certain range, so that, for example, accidentally rotating the same head S carelessly and damaging a mirror or the like attached in the vicinity can occur. It can also be prevented. The first locking portion 26a does not need to be attached to the nut 26, and may be attached to the slide pipe 22.

A fourth locking portion 28 is provided at the lower end of the decorative pipe P of the shower head portion S, as shown in FIG. The fourth locking portion 28 is in the form of a projecting step portion left uncut on the outer periphery of the base end portion of the decorative pipe P, and is provided on the partially projecting third locking portion 19c described above. The shower head portion S and the slide pipe 22 can freely rotate within a range where the end surface of the fourth locking portion 28 does not hit. Therefore, when the base end portion of the decorative pipe P contacts the mounting base 19, the shower head portion S is located closest to the top plate 11, and at this time, the fourth locking portion 28 is By engaging with the third locking portion 19c on the mounting base 19, the rotation angle of the shower head portion S is regulated. Therefore, since the swinging angle of the shower head S can be regulated within a certain range, for example, it is possible to prevent accidents such as accidentally rotating the head S and tilting the object on the top 11. You can also

When the shower head portion S is located midway between the farthest position and the closest position with respect to the top plate 11, the first and second locking portions 26a and 14b, and the third and third locking portions 26a and 14b. 4 Since the locking portions 19c and 28 do not engage with each other, the shower head portion S and the slide pipe 22 can rotate 360 degrees. However, since the support member 20 is elastically pressed against the outer peripheral portion of the slide pipe 22 by the leaf spring 21, there is a frictional resistance between the slide pipe 22 and the support member 20, so that the head portion S Also, the slide pipe 22 cannot be easily rotated, and prevents the head portion S from unintentionally swinging.

The shower head part S is provided with a discharge part 27 capable of switching the discharge water to a shower or a direct current at the tip thereof, and a shower hose 24 is provided in an inflow passage of the discharge part 27 via a driving socket (not shown). It is connected so that hot and cold water supplied from a hot and cold water mixing tap (not shown) can flow in.

When washing the hair using the shower head portion S, it is necessary to adjust the discharge height to some extent. Therefore, the base end portion of the shower head portion S is gripped with one hand, and the slide pipe 22 is lifted up against the pressing force of the leaf spring 21 as it is. If the hand is removed at the required height, the pressing force of the leaf spring 21 can again support and fix the shower head portion S at the adjusted position. After the washing of the hair, if the proximal end portion of the shower head portion S is grasped again and the slide pipe 22 is pushed down as it is, it can be fixed at a predetermined height position by the same action as described above.

The present invention is not limited to the above-described embodiments, but various modifications can be made. For example, the shapes of the first locking portion 26a, the second locking portion 14b, the third locking portion 19c, and the fourth locking portion 28 in the above-described embodiment may be changed. Further, the elastic member hooked on the plurality of support members 20 may be a spring material other than the leaf spring, and may be a rubber material or the like. Further, the shower head portion S may be composed of only a normal shower head or may be provided with other members.
