Description

[Detailed Description of the Invention] This invention relates to a shower head for use in sanitary appliances such as washstands, dressing tables, or sinks, and in particular to a shower head having a discharge head for both shower and direct current use.

Conventionally, the height of the discharge head of a shower head can be adjusted in a general manner using the Utility Model Publication No. 37-2858.
There is a drawing in the publication (Figure 6 of the drawings of the present application).

To explain with reference to FIG. 6 above, a support rod 53 is vertically supported on the wall structure 51 via brackets 52, 52, and a movable bearing 54 that is vertically slidable is supported on this support rod 53. The vertical locking hole 57 provided at the base of the shower head 56 is fitted into the arm 55 bent upward of the movable bearing 54 for support, and the height of the discharge head 58 of the shower head 56 is movable. This was done by tightening or loosening the lock handle 59 of the bearing 54.

In the case of the above, since the support rod is installed close to the wall structure, if there is a washbasin or sink below the shower head that protrudes from the vertical surface of the wall structure, these will be blocked. It was extremely difficult to operate the movable bearing. Also,
When the surface of the wall structure is formed of a decorative board, there are disadvantages such as significant damage to the wall surface when the bracket is attached.

In addition, as a general shower head equipped with a washbasin, a long flexible pipe with a free drawer connected to one end leading to a water supply source is shown in Fig. 2 of Japanese Utility Model Publication No. 37-26770 (Fig. 7 of the drawings of the present application). There is something like that.

To explain with reference to FIG. 7, a long flexible pipe 6 has one end connected to a branch pipe 62 fixed to a washbasin 61 and a mixing pipe 63 which leads to both a water supply and a hot water supply source.
4, and the other end is connected to the base 66 of the shower head 65 via an inverted truncated conical fastening ring 67, so that the base 66 supports the conical hole 68 of the branch pipe 62. In the case of the above, the base of the shower head is supported by simply dropping into the conical hole of the branch pipe through the tightening ring, so there is no need to raise the discharge head of the shower head to a higher position than the washbasin. In some cases, the user has to lift the shower head with one hand, and in turn, has to use only one hand to wash his hair or face, making it difficult to wash his hair or face as he would like.

This invention solves the above problems and makes it possible to freely and easily adjust the shower head to the required height for hair washing, face washing, and other purposes. The aim is to improve.
