Description

The present invention relates to a shower head holding adapter used by attaching to a shower hanger for holding a shower head.

Generally, the shower head is held by the shower hanger installed on the wall surface of the bathroom.
However, when the shower head is replaced with another shower head, the size and shape of the new shower head after replacement do not match the existing shower hanger, and the new shower head is properly held. There was a risk that it could not be done. Therefore, it is conceivable to replace the existing shower hanger with a shower hanger that fits the new shower head. However, in this case, it takes time to replace the shower hanger, and the existing screws for mounting the shower hanger are not suitable for mounting the new shower hanger, so that the new shower hanger cannot be mounted or the mounting state is not good. It may become stable.

Conventionally, adapters as described in Patent Document 1 and Patent Document 2 have been proposed.

The intermediate portion of the spring member 104 in the length direction is located within the rotation locus of the hooking recess 100 and the stopper portion 107. Therefore, when the holding member 96 is rotated up and down about the support shaft 93, one of the hooking recesses 100 is hooked on the spring member 104, and the rotation angle position of the holding member 96 is elastically maintained. .. Further, the upper and lower stoppers 107 regulate the vertical rotation range of the holding member 96.

Since the vertical rotation of the holding member 96 is guided by the guide protrusion 95 and the notch 101 is formed in the shaft 99, the vertical rotation of the holding member 96 is allowed by the notch 101. ..

A holding portion 108 that opens vertically and forward is formed in the front portion of the holding member 96, and the shower head 203 is detachably held by the holding portion 108.
Next, the operation of the adapter 20 configured as described above will be described.

First, when the adapter 20 of the present embodiment is attached to the existing hanger 200, a hexagon wrench is used to rotate the hexagonal hole 58 at the lower end of the screw shaft 51, and the screw acts as shown in FIG. , The cam member 61 is moved upward, and the cam surface 66 is retracted with respect to the pressing member 73 so that the pressing member 73 can move inward of the through hole 71.

In this state, the adapter shaft 41 is housed in the hanger portion 202 of the existing hanger 200 so as to be inserted from above, and the upper arm 23 is positioned on the upper surface of the shower hanger 200. Then, the adapter shaft 41 is rotated to pull down the cam member 61 by the action of the screw as shown in FIG. In this way, the cam surface 66 is lowered, and the pressing member 73 is projected and moved outward by the cam action. Therefore, the pressure contact body 75 made of the rubber material on the outer surface of the pair of pressing members 73 is pressed against the inner surface of the hanger portion 202. Therefore, the adapter 20 is fixed to the hanger 200 in the attached state.

In this state, if the front side of the adapter 20 is turned in the left-right direction, the frame 21 of the adapter 20 is positioned in the left-right direction while receiving resistance from the ring 48, and the angle in the left-right direction is arbitrarily set. Further, when the holding member 96 is rotated in the vertical direction, the spring member 104 is elastically hooked to one of the hooking recesses 100 with a click feeling, and the vertical angle is arbitrarily adjusted with a click feeling. Will be done. Therefore, the shower head 203 can be held by the holding portion 108 of the holding member 96 at arbitrary horizontal and vertical angles. Since the vertical angle adjustment range of the holding member 96 is regulated by the stopper portion 107, the shower head 203 held by the holding portion 108 is excessively downward and falls off from the holding portion 108 or is excessively upward. It is possible to prevent the wall surface 300 from colliding with the wall surface 300.

In this embodiment, the following effects can be obtained.
(1) The adapter shaft 41 attached to the hanger portion 202 of the existing hanger 200 is provided with a pressing member 73 that can move in the direction of protrusion from the outer peripheral surface thereof, and the pressing member 73 is pressed against the inner surface of the hanger portion 202. Since the screw shaft 51 is provided, the pressing member 73 is pressed against the inner surface of the hanger portion 202 by rotating the screw shaft 51.

That is, if the adapter shaft 41 of the adapter 20 is housed in the hanger portion 202 of the hanger 200 and the screw shaft 51 is turned, the adapter 20 is pressed against the existing hanger 200 by the pressure welding action of the pressure welding body 75 of the pressing member 73. The shape error is absorbed and it can be fixed without rattling without being influenced by its shape and size. Therefore, even if the shower head 203 is replaced with another one, by using the adapter 20 suitable for the shower head 203, the shower head 203 is connected to the hanger 200 via the adapter 20 without replacing the hanger 200. Can be held properly.

(2) The pressing member 73 has a high coefficient of friction and is pressed against the inner surface of the hanger 200 by a pressure welding body 75 made of a flexible rubber material. Therefore, it is possible to prevent the pressure contact body 75 from moving on the hanger 200 in the pressure contact state of the pressure contact body 75 with respect to the hanger 200, and it is possible to prevent the hanger 200 and the pressing member 73 from being partially excessively concentrated stress. Therefore, it is possible to prevent the adapter 20 from moving in the mounted state with respect to the hanger 200, and to prevent the pressure contact body 75 and the hanger 200 from being scratched.

Further, since the pressure contact body 75 is contracted against its own elasticity in the pressure contact state, the repulsive force due to the contraction is transmitted to the threaded portion between the male screw 57 and the female screw 62. Therefore, the screwed state of the screwed portion is prevented from being loosened naturally, and the fixed state of the adapter 20 can be maintained.

(3) The pressing member 73 is pressed by the action of the cam surface 66 of the cam member 61. Therefore, the pressing member 73 can be brought into a pressure contact state with a small force by utilizing the cam action.
(4) Moreover, since the pressing member 73 is subjected to a pressure welding operation by screwing the male screw 57 and the female screw 62, the pressing member 73 can be brought into a pressure welding state with a smaller force by utilizing the action of the screw.

(5) Since the hexagonal hole 58 for the hexagon wrench is provided at the lower end of the screw shaft 51, the screw shaft 51 can be easily turned by using the hexagon wrench. If a minus or plus groove is provided instead of the hexagonal hole 58, the screw shaft 51 can be turned by a screwdriver.

(6) Since the screw shaft 51 and the cam member 61 are housed in the outer cylinder 42 of the adapter shaft 41, the appearance can be improved.
(7) As shown by the solid line and the alternate long and short dash line in FIG. 3, the lateral angle of the holding member 96 for holding the shower head 203 can be adjusted, so that it depends on the structure of the bathroom, the installation position of the hanger 200, and the like. The lateral orientation of the shower head 203 in the held state can be adjusted. Therefore, the shower head 203 can be held in an easy-to-use orientation.

(8) Since the vertical angle of the holding member 96 can be adjusted, the shower head 203 can be held at an appropriate vertical angle as shown by the two-dot chain line in FIGS. 1 and 2, for example, the shower head 203. This is convenient when washing the hair while holding the adapter 20. Then, when the vertical angle of the holding member 96 is adjusted, the holding member 96 is held at the adjusting position by the hooking recess 100 and the spring member 104, and a click feeling is generated when the angle is changed. The vertical angle can be easily recognized.

(9) Since the upper arm 23 extending forward from the portion of the adapter shaft 41 faces the upper surface of the hanger 200, the upper arm 23 is the hanger 200 even if the pressure welding state of the pressing member 73 by the pressure welding body 75 is eliminated. By hitting the upper surface, it is possible to prevent the adapter 20 and the shower head 203 from falling from the hanger 200.

Therefore, a stronger fixed state can be obtained, and the pressing member 122 can be put in a loosening prevention state.

(13) Since the grip portion 125 on the lower side of the pressing member 122 is formed to have a small diameter, it is difficult to rotate the pressing member 122 with a strong force. Therefore, it is possible to prevent the pressing member 122 from being excessively pressed against both arm portions 201, and it is possible to avoid a state in which the pressing member 122 is in contact with both arm portions 201 in a locked state.

(14) Since the cam surface is composed of the spherical surface portion 123, the contact angle between the both arm portions 201 and the spherical surface portion 123 becomes smaller as the spherical surface portion 123 enters between the both arm portions 201, in other words, both. The contact surfaces of both the arm portion 201 and the spherical portion 123 approach parallel to each other. Therefore, even if a force acts in the direction in which the spherical surface portion 123 enters between the both arm portions 201, an unreasonable force is not applied to both the arm portions 201 by the spherical surface portion 123. Therefore, it is possible to prevent the spherical surface portion 123 from being pressed more strongly than necessary against both arm portions 201, and the contact area between both arm portions 201 and the spherical surface portion 123 is widened to prevent the pressing member 122 from loosening. be able to.

(15) Since the protruding portion 135 as a thick portion is formed on the back surface side of the recess 140 forming the click means of the adapter frame 111, the rigidity of the recess 140 is improved. Therefore, the deformation of the recess 140 of the substrate portion 134 can be suppressed, a click feeling between the claw member 157 and the claw 158 due to the rotation of the holding member 151 can be appropriately generated, and the holding member 151 can be formed. It can be properly held at the required rotation angle position.

(16) Since a plurality of types of hold grips 113 having different thicknesses, hardnesses, shapes, etc. are prepared, an unreasonable force acts on the hanger 200 and the adapter 110 by selecting an appropriate type of hold grips 113. There is no rattling between the two. Therefore, the adapter 110 can be appropriately supported by the hanger 200 even if the size and shape do not match.
