Reference numeral 1 denotes a grip constituting the shower head, and reference numeral 2 denotes a head portion. The grip 1 and the head portion 2 are each formed of a synthetic resin and are divided from each other. Between the grip 1 and the head part 2, an angle adjusting means 3 capable of adjusting the direction of the head part is provided.
The grip 1 has a connection screw portion 4 at a base end portion, and this screw portion 4 is connected to a hose fitting (also made of resin) 6 attached to a shower hose 5. The shower hose 5 is connected to a mixing tap (not shown) as a water supply source. The hose fitting 6 is inserted into a U-shaped support hook 7 attached to the wall of the bathroom, whereby the shower head is detachably supported by the support hook 7.
A grip-side water passage 8 extending from the base end to the tip end is formed in the grip 1. A hose insertion port 8 a is formed at the tip of the water passage 8.
The head unit 2 includes a watering plate 10 on the front surface, and a plurality of watering holes 11 are formed in the watering plate 10. The water spray plate 10 is detachably attached to the head portion 2 by a presser ring 13 through a packing material 12 such as rubber for keeping water tightness.
Further, the head portion 2 is formed with a head side water passage 14 that guides water (hot water) flowing from the grip side to the water spray plate 10, and a proximal end of the head side water passage 14 that faces the grip 1. A hose insertion port 14a is formed in the part.

The angle adjusting means 3 provided between the grip 1 and the head part 2 will be described.
The angle adjusting means 3 includes a pair of left and right flexible connecting rods 16 and 16 and a flexible hose 17 as a water passage for guiding water flow from the grip side to the head side.
The flexible connecting rods 16, 16 can be bent when an external force is applied by hand to adjust the elevation angle of the head portion 2, and have a function of maintaining the bent shape when the external force is removed.
In the case of the present embodiment, the flexible connecting rod 16 is constituted by a multi-joint rod 18. As shown in FIG. 3, the multi-joint rod 18 is formed by alternately connecting a plurality of arms 19 and a plurality of sheath tubes 20. The arm 19 includes male spherical surfaces 19 a and 19 a at both ends. The sheath tube 20 has female spherical surfaces 20a and 20a on the inner surfaces of both ends. The male spherical surface 19a of the arm 19 is fitted to the female spherical surface 20a of the sheath tube 20, and the male spherical surface 19a and the female spherical surface 20a are slidably coupled with each other with a predetermined frictional force. . Since one arm 19 is slidably fitted to the female spherical surfaces 20a and 20a of the sheaths 20 and 20 adjacent to each other, the male spherical surfaces 19a and 19a provided at both ends have joint structures. 19 and the sheath tubes 20 and 20 can be bent with each other, and are in sliding contact with a predetermined frictional force, so that the bent shape is maintained. Therefore, one arm 19 and the two sheath tubes 20, 20 constitute two joint structures that are bent at both ends of the arm 19.
When a plurality of such arms 19 and sheaths 20 are connected to each other, a multi-joint rod 18 in which a large number of joints are connected is formed.
Two such multi-joint rods 18 are stretched over the grip 1 and the head portion 2 in parallel. In this case, both ends of the multi-joint rods 18 and 18 are fitted into the grip 1 and the head portion 2, respectively, and are fixed by bonding, screwing, or other means. The joint rods 18 and 18 are mechanically connected.

A flexible hose 17 is inserted between the two multi-joint rods 18 as a water passage. As shown in FIG. 4, the flexible hose 17 includes plug connectors 22 and 22 at both ends of a rubber hose 21 such as a water hose, a pressure hose for fiber reinforcement, or a silicone rubber. An O-ring 23, 23 as a rubber-like ring-shaped sealing material is attached to 22. The insertion connector 22 has a bamboo child port 22a, and both ends of the rubber hose 21 are inserted into the bamboo child port 22a by press fitting.
Such a flexible hose 17 inserts the connectors 22 and 22 at both ends into the hose insertion port 8a of the grip side water passage 8 and the hose insertion port 14a of the head side water passage 14 so that the grip 1 and the head side are connected. The water supplied from the shower hose 5 is guided from the grip side water passage 8 to the head side water passage 14.
Further, when the connectors 22 and 22 at both ends are inserted into the hose insertion port 8a and the hose insertion port 14a, the O-rings 23 and 23 are in close contact with the inner peripheral surfaces of the hose insertion ports 8a and 14a to prevent water leakage. Can be done.
Further, a cover tube 25 made of a bellows tube made of synthetic resin, rubber or the like is spanned between the grip 1 and the head portion 2, and both ends of the cover tube 25 are tightened belts 26 or the like, and the grip 1 and the head portion. 2 is attached.
The cover tube 25 covers the pair of multi-joint rods 18 and 18 and the flexible hose 17 so as to hide and protect the multi-joint rods 18 and 18 and the flexible hose 17 from appearing to be exposed, and to shower. Improve the aesthetic sense of the entire head.

The operation of the first embodiment having such a configuration will be described.
Since this shower head has the grip 1, the user can hold and operate the grip 1, and if the shower water is discharged from the watering plate 10, the shower water can be directed to a desired location. .
And when both hands are closed, the shower head is used by being hooked on the support hook 7 on the bathroom wall. In this state, the direction of the watering plate 11, that is, the shower water injection direction is a constant direction.
When it is desired to change the direction of the shower water, the user grasps the head portion 2 and applies a force upward or downward. Then, the two multi-joint rods 18 and 18 respectively connect a plurality of arms 19 having male spherical surfaces 19a and 19a at both ends and a plurality of sheath tubes 20 alternately, and the male type of each arm 19 is provided. Since the spherical surface 19a and the female spherical surface 20a of the sheath 20 are slidably coupled with each other with a predetermined frictional force, the male spherical surface 19a and the female spherical surface 20a constitute a joint, and in this way Since a large number of joints are formed in the axial direction, the two multi-joint rods 18 and 18 can be bent and maintain a bent form.
Therefore, the direction of the head part 2 can be bent from the upright posture shown in the part (A) of FIG. 1 in the winding direction as shown in the figure (B). As a result, the shower water injection direction, that is, the elevation angle can be adjusted.
When the multi-joint rods 18 and 18 are bent in this way, the flexible hose 17 inserted inside is also bendable, so that the multi-joint rods 18 and 18 bend following the bending of the multi-joint rods 18 and 18. A water flow path from the side toward the head part 2 side can be ensured and water leakage can be prevented.

As shown in FIG. 3, the multi-joint rods 18 of the first embodiment are bent by connecting a plurality of arms 19 and a plurality of sheath tubes 20 to connect a plurality of joints. Although the flexible flexible connecting rod 16 is configured, if at least two joint portions are formed, the amount of bending can be increased as compared with the conventional single spherical joint type.
For this purpose, as shown in FIG. 5, one arm 19 having male spherical surfaces 19a and 19a at both ends and two sheath tubes 28 and 28 having female spherical surfaces 28a at one end are connected to each other. If it connects so that sliding is possible, a flexible joint part can be formed in two places.
Therefore, when the joint rod 18 is constructed, it is implemented by using at least one arm 19 with male spherical surfaces 19a, 19a at both ends and a pair of sheath tubes 28, 28 having a female spherical surface 28a at at least one end. In order to further increase the joint portion, a sheath tube 20 having female spherical surfaces 20a, 20a at both ends may be added and connected.

Next, Example 3 will be described with reference to FIG.
FIG. 6 is a sectional view of the shower head according to the third embodiment.
In the first embodiment, an example in which the multi-joint rod 18 is used as the flexible connecting rod 16 has been described. However, in this third embodiment, as a flexible connecting rod that can be bent and deformed and maintains its bent shape when bent. An example using a soft metal wire is shown.
As the soft metal, a soft iron wire, copper or copper alloy wire, etc. are effective, and a metal wire that can withstand repeated deformation is desirable.
Moreover, although it is also possible to use one wire independently, the wire 30 which twisted 2 or 3 or more bundles can be used.
Two twisted wires 30 are stretched between the grip 1 and the head portion 2 in parallel on the left and right sides of the flexible hose 17. These twisted wires 30 and 30 are fitted into the grip 1 and the head portion 2 at both ends, and are fixed by bonding, screwing, or other means. For this reason, the grip 1 and the head portion 2 are twisted together. The wires 30 and 30 are mechanically connected.
Other configurations may be the same as those in the second embodiment, so the same members are denoted by the same reference numerals and description thereof is omitted.
In the case of Example 3, when a force is applied to change the direction of the head portion 2, the twisted wires 30 and 30 are bent and deformed in the direction in which the force is applied, and when the bending force is released, the wire is bent. Keep in shape. Therefore, the direction of the head part 2 can be changed in the vertical direction, and the jetting direction of the shower water can be adjusted.

  As described above, according to the present invention, since the direction of the head portion can be changed, the shower water injection direction can be freely changed. Moreover, the angle adjusting means for connecting the grip and the head is a flexible connecting rod that can be bent and deformed. Therefore, the bending amount can be increased as compared with the conventional single spherical joint type, and the injection direction can be adjusted. The range becomes larger and the usability improves.
