By bending the flexible tube 4, the ejection surface of the nozzle 9 is formed. Can be oriented in any direction. Various types of nozzles 9 can be selected according to the purpose of use, for example, a shower nozzle that ejects only hot water, a jet nozzle that ejects a mixed fluid of hot water and air, a jet flow that switches between a shower flow and a jet flow. If the composite nozzle etc. to be selected becomes the target of selection, and if it is further classified,
Each of the nozzles is divided into a nozzle for continuous jetting of hot and cold water and a nozzle for intermittent jetting, and a desired nozzle is used. In this embodiment, a composite nozzle having a jet ejection hole 5 in the center of the nozzle ejection surface and a shower ejection hole 6 around the ejection hole 5 is adopted. By operating a lever 7, a jet jet and a shower jet are formed. It can be used by switching between and.

The handle 3 has both sides and a back face (later-described engaging protrusions).
A plurality of engaging recesses 8 are formed at a pitch at equal intervals in the length direction on the surface facing the 17).

Further, a hose 10 leading to the discharge side of a hot water supply pump (not shown) is fitted to the base end side of the handle 3. Further, on the base end side of the handle 3, a rotating sleeve 11 for adjusting the jetting pressure of hot and cold water is provided.

On the other hand, the holder 2 has a holding function of the nozzle 1 with a handle and a backing function of a bather, and a suction cup 12 (Fig. 2) is fixed to the back side of the holder 2. It is adsorbed and fixed to a desired inner wall surface position of the bathtub 13. The main body portion 14 of the holder 2 may be integrally formed of a plastic material, but in the present embodiment, the surface side of the main body portion 14 is constituted by a flexible member 15 such as rubber, and a cushion suitable for a backrest is formed.

A vertical fitting groove 16 is formed in the central portion on the front surface side of the holder 2, and a plurality of (two in the drawing) engagements are made on the wall surface of the fitting groove 16 (bottom wall surface of the groove 16 in the drawing). The convex portion 17 is formed. The engagement protrusions 17 are formed in a shape that fits in the engagement recesses 8 on the handle 3 side, and the arrangement intervals (arrangement pitches) of the engagement protrusions 17 are the same as the arrangement intervals of the engagement recesses 8. Match. The opening width of the fitting groove 16 on the opening end side is set to be slightly smaller than the diameter (width) of the handle 3. When the handle 3 is pushed in from the opening end side, the sidewall of the opening end of the groove 16 is set. Is elastically expanded to fit the handle 3 into the fitting groove 16 with an elastic force.

Further, the surface of the holder 2 is an inclined surface that is inclined from the left and right ends toward the central fitting groove 16 side toward the back side (direction of thinning), and the surface side of the holder 2 is used as a backrest. At this time, a gap is formed between the center of the surface of the holder 2 and the back so that the spine does not hit the surface of the holder 2.

The first embodiment is configured as described above, and
An example of its use will be described.

First, as shown in FIG. 2, the holder 2 is fixed to the bathtub 13 or the tile surface 18 near the bathtub by using the suction cup 12. In this state, if the handle 3 is pushed in together with the engaging recess 8 and the engaging protrusion 17 from the opening end side of the fitting groove 16, the side wall of the opening end is elastically expanded and the handle 3 is fitted. The engaging concave portion 8 and the engaging convex portion 17 are engaged with each other (fitting) at the same time, and the nozzle 1 with the handle is held by the holder 2. In this holding state, since the engaging concave portion 8 and the engaging convex portion 17 are engaged with each other, the handle 3 does not slide down due to its own weight, and furthermore, when the fitting of the handle 3 is completed, the fitting groove 16 Since the opening end is closed and contracted from the expanded state to the original state by the elastic restoring force and the opening width of the opening end is smaller than the width of the handle 3, the handle 3 does not come out of the fitting groove 16 naturally. Rather, the nozzle 1 with handle is held stable in the desired position. When hot water is supplied to the nozzle 9 in this holding state, the jet flow is ejected from the nozzle 9 toward the stiffened portion, and you can enjoy a massage in the bath without holding the nozzle 1 with the handle in your hand (Fig. 2 (a), (b),
(c)). Then, during this massage, the surface of the holder 2 functions as a backrest portion, but as described above, since the central portion of the backrest surface is formed with a relief so as not to hit the spine, the spine is the surface of the holder 2. You can comfortably take a massage while taking a bath without feeling uncomfortable.

At the time of this massage, the handle 3 is once pulled out from the fitting groove 16, and the engaging concave portion 8 and the engaging convex portion 17 are engaged with each other (pair).
By changing and fitting, the height position of the nozzle 9 can be arbitrarily changed, and different parts can be massaged according to preference. Further, as shown in FIGS. 2 (a) and 2 (b), the nozzle 9 side of the nozzle 1 with a handle may be placed downward (see FIG. 2).

In both cases, a jet nozzle and a shower nozzle are constituted by a compound nozzle which can be switched and selected by operating the lever 7, but of course other types of nozzles may be used, and the number of nozzles 9 is two. However, the number of nozzles may be three or more.

Similar to the first embodiment, the engaging recesses 8 are formed in the handle 3, but in the second embodiment, the engaging recesses 8 form valley grooves on the outer surface of the handle 3 at equal pitch intervals. It is formed by installing.

On the other hand, the fitting groove 16 of the holder 2 is provided with a holding member 20 having an arc-shaped cross section, which is shaped like a plastic pipe divided in half. The chevron-shaped projections that fit into the troughs are formed at the same pitch intervals as the troughs, and these serve as anti-slip folds to form the engaging projections 17 that engage with the engaging recesses 8.

The opening width (inner diameter width) of the holding member 20 is set to be slightly smaller than the outer diameter of the handle 3. Therefore, similarly to the first embodiment, the handle 3 has the opening end of the holding member 20. The side wall of the is elastically opened and fitted into the fitting groove 16 to prevent unintended removal. Further, the half-divided surface 21 of the holding member 20 is in a state of being retracted from the backrest surface of the holder body 14, so that the spine does not hit the half-divided surface 21 when the surface of the holder 2 is used as a backrest surface. Has become.

According to the second embodiment, the height position of the nozzle 9 can be arbitrarily changed by changing the engaging position of the engaging concave portion 8 and the engaging convex portion 17 by attaching and detaching the handle 3.
