Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an improvement of a shower head whose water spray angle can be adjusted.

(Prior art and its problem) Conventionally, various structures have been known as a shower head capable of adjusting a watering angle and changing a watering state by rotating a handle provided on the showerhead, for example, actual opening. There are those having the structure described in Japanese Patent Laid-Open No. 59-150543. According to the structure described in the publication, the water spray plate moves along with the rotation of the handle, and in such a structure, the water spray angle cannot be visually confirmed by the rotation angle of the handle, There is a drawback that the adjustment of the water spray angle is troublesome, and there are drawbacks such that the engagement portion is worn and the screw portion is damaged when the handle is continuously rotated. Furthermore, with this type of conventional product, it is necessary to continue turning the handle to obtain the desired sprinkling angle, and there is the problem that the sprinkler plate and the support of the sprinkler plate will fall off with rotation. The handle had to be rotated many times to adjust the water flow, which made it difficult to obtain an appropriate water spray angle.

(Means for Solving the Problems) The present invention has been devised in view of the above-mentioned conventional problems, and does not provide a shower head that does not drop the water spray plate and that can adjust the water spray angle by an easy operation. For the purpose of
The gist of the present invention is that in a shower head configured so that the water spray plate is retracted by rotating the rotation lever attached to the head of the main body to adjust the water spray angle, the front side of the shower head is inside the main head. An opened storage chamber is formed, and a regulation plate protruding forward is fixedly provided in the storage chamber, and an outer periphery of the cylindrical rotation lever attached to the front side of the storage chamber is outward. A handle is formed in a protruding shape, and on the rear surface of the rotation lever, a regulation projection that abuts on the regulation plate and regulates rotation of the rotation lever when the handle is rotated within a predetermined angle range is provided to the storage chamber side. That is, the protrusion is formed.

(Operation) Since the rotation restricting means including the restricting plate and the restricting protrusion is arranged in the head portion of the main body, the shower head has a neat appearance, and the restricting protrusion comes into contact with the restricting plate to restrict the rotation range. The turning range is narrowed, and accordingly, the turning operation can be easily performed, and the sprinkler plate and the like can be favorably prevented from falling off. In addition, the standard of the water spray angle can be easily determined by the position of the handle, and the water spray angle of the shower water ejected from the shower head can be easily visually determined from the outside.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is an exploded perspective view of a shower head of this example, FIG. 2 is an external perspective view of an assembled state, and FIG. 3 is a front view of the assembled state. Further, FIG. 4 shows a side sectional view in an assembled state.

In the figure, the main body 2 of the shower head 1 is formed in a rod shape that can be held by a hand, and the inside thereof is hollow to form a water passage for passing hot water. A circular head 2a is formed at the upper end of the main body 2, and a lower member 3 is attached to the lower end of the main body 2 in a watertight manner. A hose can be connected to the hose connecting portion 3a that is protruded from the hose so that hot water or the like can be supplied from the hose to the head portion 2a through the inside of the main body 2.

The inside of the head 2a is a storage chamber S that is open to the front side, and a cylindrical support portion 4 is formed in a protruding shape in the center of the storage chamber S, and the support portion 4 has four sides at the periphery. A locking plate 5 is projected in a cross shape, and a screw hole 4a is formed in the central portion. Further, one side of the locking plate 5 is further extended outward to form a restriction plate 6.

A rotation lever 7 can be attached to the storage chamber S of the head portion 2a from the front side. The rotation lever 7 includes a cylindrical outer ring 7a and an inner ring 7 inside thereof.
b, and the outer ring 7a has a handle 9 projecting outward.
Are formed. Further, in the inner ring 7b, a spline groove (not shown) carved in a cross shape opening to the front side is formed. Further, on the rear surface side of the rotation lever 7, a pair of restricting protrusions 8 are formed in a protruding shape.

Therefore, when the rotation lever 7 is attached to the head portion 2a, the rotation is possible within a range in which the regulation protrusions 8 and 8 come into contact with the regulation plate 6. That is, FIG. 5 shows the operating state of the plane, and when the rotation lever 7 is attached to the head 2a and rotated, the pair of restricting projections 8 rotate the peripheral edge of the locking plate 5. , Any one of the regulation projections 8 is rotated until it abuts on the regulation plate 6, and the rotation is locked in a state of abutting on the regulation plate 6. That is, in this example, the rotation lever 7 can be rotated within a rotation range of about 180 °, and the handle 9 of the rotation lever 7 can be rotated by 180 °.

Further, a stopper 10 is brought into contact with the supporting portion 4 of the head portion 2a from the front side, penetrates the central portion of the stopper 10 and a mounting screw 13 is screwed into the screw hole 4a from the front side. Thus, the stopper 10 can be fixedly mounted on the support portion 4. Since the cross-shaped engaging groove 10a is formed on the rear surface side of the stopper 10, the engaging groove 10a of the stopper 10 engages with the locking plate 5 and the stopper 10 is firmly fixed to the support portion 4. . An outer screw 10b is threaded on the peripheral portion of the stopper 10.

When the stopper 10 is fixed to the head 2a by the mounting screw 13, the rotation lever 7 is rotatably attached to the head 2a by the stopper 10.

As shown in FIG. 4, a bush ring 16 and a packing 17 are provided on the sliding portion of the head 2a and the rotation lever 7.
Is installed to ensure water tightness.

In this state, the main cap 11 and the sprinkler plate 12 from the front side.
Is attached. That is, the water sprinkling plate 12 is formed in a ring shape, and has a large number of water sprinkling grooves formed in the outer peripheral portion thereof in the axial direction, and is fitted and integrated with the outer peripheral portion of the main cap 11.

The main cap 11 has four cross-shaped splines 11b, 11b, 11b, 11b extending rearward.
Is formed, and the splines 11b, 11b, 1
1b and 11b are fitted in the spline groove formed in the inner ring 7b of the rotation lever 7, and the main cap 11 and the sprinkler plate 12 are fitted in the rotation lever 7 so as to be retractable in the front-rear direction. An inner screw 11a is formed on the inner peripheral surface of the main cap 11, and the inner screw 11a is screwed into the outer screw 10b of the stopper 10.

Further, from the front side of the main cap 11, the packing 14
The cap 15 is attached via the, and the cap 15, the main cap 11, and the rotation lever 7 are visually recognized from the front side. Since the locking projection 15b is formed on the back side of the cap 15 and the turning groove 15a is formed on the front side, a coin or the like is fitted into the turning groove 15a to easily attach the cap 15 to the main cap. Since the mounting screw 13 is exposed in this state, the mounting screw 13 is loosened from the front side with a screwdriver or the like, and the main cap 11, the stopper 10, and the rotation lever 7 are headed as described above. It can be removed and disassembled more easily than 2a.

In the assembled state as shown in FIG. 4, the handle 9 is held on the head 2a and the rotation lever 7 is rotated, so that the rotation of the rotation lever 7 causes the main cap 11 and the sprinkler to sprinkle through the spline 11b. Board 12
Will rotate, but at this time, the stopper 1
Since 0 is fixed to the head 2a side and the main cap 11 is screwed with the outer screw 10b of the stopper 10, the main cap 11 and the sprinkler plate are guided along the outer screw 10b of the stopper 10 as they rotate. 12 will move forward or backward. Accordingly, the rotation of the rotation lever 7 causes the water spray plate 12 together with the main cap 11 to move in and out of the rotation lever 7, and the water spray angle from the water spray groove formed in the peripheral edge portion of the water spray plate 12 is adjusted.

That is, the state will be described with reference to FIGS.
As shown in FIG. 6, three kinds of water sprinkling grooves A, B, C having different inclination angles are alternately arranged on the peripheral edge of the water sprinkling plate 12, and as described above, the rotation lever 7 is rotated. When the sprinkler plate 12 is moved in and out in the front-rear direction accordingly, for example, in the state shown in FIG. It will be ejected almost straight.

Further, when the sprinkler plate 12 is located outside the rotation lever 7 as shown in FIG. 8, the shower water passing through the sprinkler groove is diffused to the outside as shown by the arrow.

Therefore, if the water spray plate 12 is moved forward with respect to the rotation lever 7, the water spray angle is widened, and if the water spray plate is moved rearward with respect to the rotation lever 7, the water spray angle is narrowed.

Further, as described above, the water spray grooves A, B, and C have different inclination angles, the water spray groove A has an inclination angle of about 9 °, and the water spray groove B has an inclination angle of about 6 °. , The sprinkling groove C has an inclination angle of about 3 °, so that the sprinkling grooves A,
The spray angles of the shower water sprayed from B and C are different, and the shower water sprayed from the spray plate 12 is sprayed over almost the entire area within the adjusted spray angle.

By rotating the rotation lever 7 in this manner, the sprinkling plate 12 appears and disappears in the front-rear direction, and the sprinkling angle of the shower water spouted is adjusted well, but in the present example, the rotation lever 7 is rotated. The rotation range is
Since the rotation range is regulated by the regulation means constituted by the regulation projection 8 and the regulation plate 6, the rotation is possible only within this range. That is, the handle 9 is 18 in this example.
It is possible to rotate in the range of 0 °.
In the figure, if the water spraying angle is set to be maximum when the handle 9 is in the horizontal state in the front left direction, the water spraying angle is minimized by turning the handle 9 by 180 ° and rotating it to the right horizontal position. Can be a handle 9
The water spraying angle in the intermediate state can be obtained at the position where the stand rises in parallel with the main body 2, and the guideline of the watering angle can be easily determined by the position of the handle 9, and the shower spouted from the shower head 1 The water sprinkling angle can be easily visually determined. For example, when the handle 9 is located at the intermediate position, the operation may be performed within a range of 90 ° to the left and right in order to adjust to the minimum water spray angle or the maximum water spray angle, and the operation is extremely easy.

Further, if a picture or the like is displayed at the position of the maximum water spray angle or the minimum water spray angle, the water spray angle can be visually checked very easily, and the operation becomes easier. Further, in this example, since the turning range of the handle 9 is 180 °, the handle 9 does not come into contact with the root of the head portion 2a, and damage and dirt can be prevented well.

Further, since the rotation range of the rotation lever 7 is regulated to 180 ° as described above, the rotation lever 7 does not rotate unnecessarily, so that the sprinkler plate 12 and the main cap 11 are not rotated.
Will not be taken out excessively and will not be pulled out, so that the sprinkling plate 12 and the like will be favorably prevented from being pulled out.

In this example, the rotation lever 7 is rotated in the range of 180 °.
Although the rotation of the control lever 8 is restricted, by appropriately changing the formation position of the restriction protrusion 8 protruding from the rotation lever 7,
The rotation range can be changed, and the stopper 1
0 external screw 10b and main cap 11 internal screw 11
By changing the pitch or the like of a, it is possible to arbitrarily change the moving amount of the sprinkler plate 12 with respect to the rotation lever 7 that appears and disappears.

(Effects of the Invention) The present invention provides a shower head configured to adjust a water spray angle by rotating a rotation lever attached to the head of the main body so that the water spray plate is retracted and retracted. A storage room with a front opening is formed in
A regulation plate protruding forward is fixedly provided in the storage chamber, and a handle is formed on the outer circumference of the cylindrical rotation lever attached to the front side of the storage chamber so as to project outward. A regulation projection is formed on the rear surface of the rotation lever, which abuts on the regulation plate when the handle is rotated within a predetermined angle range and regulates the rotation of the rotation lever. Since the rotation restricting means consisting of the plate and the restricting projection is arranged in the head of the main body, the shower head has a neat appearance, and the restricting projection comes into contact with the restricting plate to restrict the rotating range so that the rotating range is reduced. It becomes narrower, so that the turning operation can be easily performed, and the sprinkler plate and the like can be favorably prevented from falling off.

Further, there is an effect that the standard of the sprinkling angle can be easily determined by the position of the handle, and the sprinkling angle of the shower water ejected from the shower head can be easily visually determined from the outside.
