As a result, in the shower hook A of the present embodiment, even when hot water is discharged from the held shower head 2 and the reaction force acts thereon, the shower head 2 can be firmly and firmly held. It is possible to reliably and favorably prevent inconvenience such as the shower head 2 being pulled out from the shower hook A.

Next, the head-side grip mechanism 9 of this embodiment is arranged in a clip lever insertion hole (movable hole) 18 provided in the rear wall portion 16 of the hook body 7, and is inserted through the shaft insertion hole 22. A clip lever (rotating member) 47 which is rotatably supported by a pivotally supported rotating shaft 21 in the vertical direction, and a grip which is integrally attached to the front surface of the upper end of the clip lever 47. A member (hook packing) 48 and a spring member (biasing member) 49 which is provided with one end connected to the rear surface of the upper end side of the clip lever 47 and biases the upper end side of the clip lever 47 forward. It is

The grip members 46 and 48 are made of, for example, a rubber material or an elastomer resin material, or are formed with vertical stripes, horizontal stripes, oblique stripes, or ridged surfaces so that the friction coefficient of the surface is large. I'm trying to be

In addition, the clip lever 47 is provided with an inclined surface 47a on the front surface of the upper end, which is gradually inclined forward from the upper end toward the lower end, and the inclined surface 47a is used as a guide surface.

In the head-side grip mechanism 9, when the hose joint 2a of the shower head 2 is inserted from above into the insertion hole 19 of the hook body 7, the hose joint 2a contacts the grip member and the upper end side of the clip lever 47 is pushed backward. At the same time, the clip lever 47 automatically rotates around the axis O4 of the rotating shaft 21 .

At this time, first, since the upper end of the clip lever 47 is provided with an inclined surface 47a, when the hose joint 2a of the shower head 2 is inserted from above, the lower end of the hose joint 2a hits the inclined surface 47a, As the hose joint 2a is inserted downward, the inclined surface 47a functions as a guide surface, so that the clip lever 47 can be preferably rotated.

Furthermore, at this time, the biasing force of the spring member 49 acts on the clip lever 47 so as to resist the rotation of the clip lever 47 . As a result, in a state in which the hose joint 2a is inserted into the insertion hole 19 of the hook body 7 and the shower head 2 is held, the grip member 48 attached to the clip lever 47 is moved by the urging force of the spring member 49 to the rear of the hose joint 2a. The outer surface of the side and the outer surface of the upper side on the rear side are pushed forward and supported, and the shower head 2 can be firmly held within the insertion hole 19 of the hook body 7 .

When the hose joint 2a is inserted into the insertion hole 19 of the hook body 7, the hooking surfaces 25a of the hooking portions 25 provided at the tips of the pair of side wall portions 17 of the hook body 7 come into contact. In this embodiment, for example, the lower side of the engaging surface 25a is configured to strongly abut.

As a result, the biasing force of the spring member 49 is transmitted from behind to the hose joint 2a of the shower head 2 inserted into the insertion hole 19 of the hook body 7 via the clip lever 47 (grip member 48), and the hose joint 2a moves forward. At the same time, the front side of the hose joint 2a is strongly pressed against the hooking surfaces 25a of the pair of hooking portions 25 provided at the ends of the pair of side wall portions 17 of the hook body 7, thereby firmly holding the hose joint 2a. be able to hold.

Also, when the shower head 2 is removed from the shower hook A, the clip lever 47 is automatically rotated by the biasing force of the spring member 49, and the shower head 2 is automatically returned from the held state to the initial state. can.

On the other hand, the hose holding mechanism (shower head pull-out prevention mechanism) 10 of the present embodiment is constructed by using a part of the components also as the head-side grip mechanism 9 .

Specifically, as shown in FIGS. 5, 6, 10 to 13, 15, and 20 to 23, the hose holding mechanism 10 of this embodiment includes a clip lever (rotating member) 47, A pair of left and right hose clip insertion holes (restriction member insertion holes) 20 provided in the rear wall portion 16 of the main body 7 and a pair of left and right hose clip insertion holes 20 are inserted so as to be forward and backward. It comprises a pair of left and right hose clips (restraining members) 50 that are pressed by the lower end of a clip lever 47 that advances and retreats in the front-rear direction T2 according to rotation and that follows the front-rear movement.

Each hose clip insertion hole 20 is provided with a clip guide projection (guide projection) 20a at a predetermined position on the inner surface thereof. Further, each hose clip 50 advances by a predetermined amount and abuts on the clip guide convex portion 20a, so that the tip portions of the pair of left and right hose clips 50 are guided to approach each other until the separation distance L becomes a predetermined separation distance. A clip contact guide portion (contact guide portion) 50a is provided.

In the hose holding mechanism 10 constructed in this way, the hose 2b is passed between the pair of side wall portions 17 of the hook body 7 and thus between the pair of hose clips 50 from the front and arranged in the insertion hole 19, and the hook The shower head 2 (hose joint 2a) is inserted into the insertion hole 19 of the main body 7 from above. Then, the shower head 2 comes into contact with the clip lever 47, and following the insertion of the shower head 2, the clip lever 47 rotates in one direction. Since the clip lever 47 rotates in one direction and the lower end portion of the clip lever 47 moves forward, the pair of left and right hose clips 50 are pressed by the lower end side of the clip lever 47 and follow the hook body in a synchronous manner. It advances into the insertion hole 19 of 7, and protrudes.

A lower hose 2b connected to the hose joint 2a is surrounded by a portion surrounded by a pair of projecting hose clips 50 and the inner surface of the hook body 7. - 特許庁Further, when the hose joint 2a of the shower head 2 is completely inserted into the insertion hole 19 of the hook body 7 and held, the separation distance L (L2) between the tips of the pair of hose clips 50 of the hose holding mechanism 10 becomes The thickness of the hose 2b becomes smaller than that of the hose 2b, and the hose 2b does not come off from between the tips of the pair of hose clips 50. - 特許庁

That is, the pair of hose clips 50 have a separation distance L (L1) between the tips in the state of the initial posture larger than the diameter of the hose 2b (the size of the object to be restrained), and the insertion hole 19 is inserted from above into the shower head 2 ( When the hose joint 2a) is inserted, the separation distance L (L2) of the tip becomes smaller than the diameter of the hose 2b (the size of the object to be restrained), and the hose 2b can be restrained.

Thus, in the shower hook A of this embodiment, the shower head 2 can be held, and the hose 2b connected to the shower head 2 can be automatically restrained and held. Therefore, the hose 2b is held not only by the hook body 7 and the head-side grip mechanism 9 (apart from the grip mechanism 9), but also by the hose holding mechanism 10, and the shower head 2 in the held state can be restrained.

When the shower head 2 is removed from the shower hook A, the clip lever 47 is automatically rotated by the urging force of the spring member 49 to retract the pair of hose clips 50 and return them to their original positions to hold the hose 2b. The state can be automatically released.

Therefore, in the shower hook A of this embodiment configured as described above, by providing the hose holding mechanism (shower head pull-out prevention mechanism) 10, not only the friction (engagement) due to the stepped portion, the projecting portion, and the taper portion , the shower head 2 can be inserted into the insertion hole 19, and the hose 2b and thus the shower head 2 can be mechanically restrained and held.

Therefore, according to the shower hook A of the present embodiment, for example, when the shower head 2 is hooked and held by the shower hook A arranged below, the hose 2b connected to the shower head 2 is connected to the counter or the like. It is possible to reliably prevent the shower head 2 from being pulled out even when a force acts to pull the shower head 2 upward due to contact or the like.

That is, it is possible to reliably prevent the shower head 2 in the held state from coming off due to the recoil when spouting water, and it is possible to greatly improve the handleability and convenience of the shower hook A as compared with the prior art.

Although one embodiment of the shower hook according to the present invention has been described above, the present invention is not limited to the above one embodiment, and can be appropriately modified without departing from the scope of the present invention.

For example, in the present embodiment, the handrail 3 extending horizontally is used as a shower bar, and the shower hook A according to the present invention is attached to the handrail 3 . On the other hand, the shower hook A according to the present invention is attached to the shower bar 3 extending in the horizontal lateral direction T1, the oblique direction, and the vertical vertical direction T3, and the shower bar 3 configured by combining these extending directions. It is of course possible to use Also, the shower bar 3 to which the shower hook A is attached may not necessarily serve as a handrail.

Further, in the present embodiment, the shower head pull-out prevention mechanism 10 according to the present invention is described as holding the hose 2b, but it may be configured to hold the shower head 2 (hose joint 2a, etc.). Also in this case, it is possible to obtain the same effects as in the present embodiment.

Furthermore, if the showerhead 2 held by the shower hook A can be prevented from being pulled out due to the recoil when water is spouted, the configuration of the showerhead pull-out prevention mechanism 10 does not necessarily have to be limited as in the present embodiment. That is, as long as the shower head 2 can be inserted into the insertion hole 19 and followed by it to constrain the shower head 2 and the hose 2b, there is no particular need to limit the configuration.

For example, in the present embodiment, the shower head 2 is inserted into the insertion hole 19, and a pair of hose clips (a pair of restraining members) 50 are advanced to surround and restrain the hose 2a. However, the shower head 2 or the hose 2a may be sandwiched between a pair of restraining members 50 and restrained. In this case, the shower head 2 can be restrained and held more firmly.
