[0002]

[Prior art]

 FIG. 6 shows an example of a conventional slide shower hook 21. Usually, this kind of shower hook 21 includes a hook portion 22 for locking the shower head, and a handle 25 for operating the stop position of the main body portion 23 with respect to the slide bar 40 inserted into the insertion hole 23a of the main body portion 23. It has and.

A conventional mechanism for stopping the main body 23 of the shower hook 21 with respect to the slide bar 40 has a structure as shown in FIG. That is, the main body portion 23 is provided with a through hole 23b penetrating from the end surface on the opposite side of the hook portion 22 to the insertion hole 23a through which the slide bar is inserted, and the push member is pushed toward the insertion hole 23a side of the through hole 23b. Interior 28. On the other hand, a female screw portion 23c is formed on the inner peripheral surface of the through hole 23b, and the bolt portion 27 of the handle 25 is screwed into the female screw portion 23c. With such a configuration, when the handle 25 is rotated to screw the bolt portion 27 toward the insertion hole 23a, the tip of the bolt portion 27 presses the push body 28, and the push body 28 is inserted into the insertion hole 23a. A pressing force is applied to the side peripheral surface of the slide bar thus made, whereby the main body portion 23 of the shower hook 21 can be stopped at a desired position of the slide bar.

[Problems to be solved by the device]

 The conventional slide shower hook 21 has the following drawbacks. Since the rotating operation of the handle 25 is performed manually, it is very difficult to make the tightening force constant when the shower hook 21 is stopped by the slide bar 40. Moreover, the psychology of the user tends to give an excessively large tightening force. Therefore, the pressing body 28, which is generally made of synthetic resin, is easily worn. Therefore, even if the orientation of the grip portion 26 of the handle 25 in the final tightened state when the shower hook 21 is stopped is initially set to an angle that is easy for the user to operate, By repeated use, the pushing body 28 is gradually shortened due to wear, and the direction of the grip portion 26 of the handle 25 is gradually changed, which finally makes it difficult for the user to operate the handle 25. Moreover, with the conventional shower hook 21, it is difficult to properly adjust the direction of the handle 25.

Further, as described above, when an excessively large tightening force is applied, a large load acts between the female screw portion 23c of the main body portion 21 and the bolt portion 27 of the handle 25. The main body 21 and the handle 25 had to be made of metal having excellent wear resistance and fracture resistance. Therefore, the conventional shower hook 21 has a drawback of high cost.

Further, since the pushing member 28 is pushed toward the side peripheral surface of the slide bar by rotating the handle 25 and screwing the bolt portion 27, the handle 25 is attached to the main body portion 21. On the other hand, there is a problem that it moves backwards and forwards, which makes it unattractive and constrains the design.

[Means for Solving the Problems]

 The present invention provides a slide type shower hook having a novel structure that can solve the above-mentioned conventional drawbacks, and is characterized in that the slide shower hook is inserted into the insertion hole of the main body. The connecting bush is interposed between the pusher that moves forward and backward with respect to the main body and the handle that operates the forward and backward movement of the pusher so that it does not fall off from the main body. Are connected by screw fitting, and the handle and the connecting bush are connected using a detachable rotation prevention structure, and the locking protrusion formed on the inner surface of the handle is within the range of the notch provided in the stopper. By locating the handle so that it can move, the rotation angle of the handle is restricted within a predetermined range.

[0009]

[Action]

 In the shower hook according to the present invention, a connecting bush is connected to a pusher that applies a pressing force to the slide bar by screw fitting, and a handle is connected to the connecting bush by using a rotation stop structure. The connecting bush is rotatable with respect to the main body and does not fall off from the main body. Therefore, by rotating the handle, it is possible to rotate the connecting bush that is connected using the anti-rotation structure, and thus to move the pusher, which is screwed into the connecting bush, back and forth without moving the handle back and forth. it can.

Moreover, the rotation range of the handle is regulated within a predetermined range by setting the range of movement of the locking projection provided on the inner surface of the handle within the notch provided in the stopper of the main body. In other words, the rotation angle of the handle can be set so that the amount of forward movement of the pusher is the minimum necessary to stop the shower hook on the slide bar, and thus excessive tightening force is needed. It will not work.

【Example】

 FIG. 1 shows an embodiment of a slide type shower hook 1 according to the present invention, in which the pusher 5, the connecting bush 6, and the handle 7 are disassembled from the main body 3 of the shower hook 1. It is a perspective view. The shower hook 1 is provided with a hook portion 2 having an insertion space 2a for locking a shower head at one end of a main body portion 3 and a handle 7 at the other end. The handle 7 is for switching operation of stopping and moving the main body portion 3 with respect to the slide bar inserted through the insertion hole 3a. A pusher 5 and a connecting bush 6 are provided inside the main body 3, and a cosmetic cover 30 is provided on the surface of the main body 3.

FIG. 2 shows the internal structure of the shower hook 1 in the assembled state. The means for stopping the shower hook 1 with respect to the slide bar is by moving the pusher 5 forward toward the insertion hole 3a of the main body 3, and the mechanism is as follows in this embodiment. The configuration is adopted. The main body 3 is provided with a region where the pressing surface 5a faces the insertion hole 3a and the pusher 5 is housed therein, and the inner surface of the region is fitted with the protrusion 5b provided on the side surface of the pusher 5. The groove 3b is formed. Therefore, the pusher 5 can move back and forth along the groove 3b without rotating. Further, on the side of the pusher 5 opposite to the pressing surface 5a, a spiral shaft 5c having a peripheral surface engraved with a male screw is provided.

A connecting bush 6 having a female screw portion 6b is interposed between the pusher 5 and the handle 7, and the spiral shaft 5c is screwed into the female screw portion 6b. , The connecting bush 6 is rotatably connected to the pusher 5. A ridge 6a is circumferentially provided on the side surface of the connecting bush 6, and the ridge 6a is engaged with a stopper 4 provided at an end of the main body 3 on the handle 7 side to connect the connecting bush 6a. Are prevented from coming out of the main body 3.

In this embodiment, as a rotation preventing structure between the connecting bush 6 and the handle 7, a serration structure S including a large number of V-shaped projections along the axial direction is provided as shown in FIG. Then, as shown in FIG. 3, by engaging the serration structure, both of them rotate integrally. Further, by screwing the screw 9 inserted through the side end surface of the handle 7 into the nut member 8 mounted in the connecting bush 6, the handle 7 is detachably fixed to the connecting bush. A cosmetic cap 10 that covers the head of the screw 9 is attached to the side end surface of the handle 7.

Based on such a configuration, when the pusher 5 of the shower hook 1 is in the retracted position shown in FIGS. 4A and 4B, the handle 7 is moved in the direction of arrow P (D) in the same figure. When it is rotated by a predetermined angle to the position shown in Fig. 5, the connecting bushes 6 connected by the serration structure rotate simultaneously. Since the connecting bush 6 is prevented from coming off by the stopper 4 of the main body portion 3, the pusher 5 connected by screw fitting is guided to the groove 3b (see FIG. 2) of the main body portion 3 and is shown in FIG. As shown in (C), it moves forward in the direction of the insertion hole 3a. As a result, the pressing surface 5a of the pusher 5 presses the side peripheral surface of the slide bar inserted through the insertion hole 3a of the main body 3, and the shower hook 1 is stopped at the desired position of the slide bar. Of course, when the handle 7 is reversely rotated from the state shown in FIG. 7D to the state shown in FIG. 7B, the pusher 5 is retracted to the position shown in FIG.

Since the handle 7 and the connecting bush 6 are connected by using the serration structure as described above, there is an advantage that the meshing position between the two can be appropriately changed. That is, even if the position of the handle 7 that stops the shower hook 1 changes due to wear of the pusher 5 due to repeated use, etc., simply remove the handle 7 from the connecting bush 6 and change the meshing position of the serrations. Thus, the position of the handle 7 in the tightened state when the shower hook 1 is stopped by the slide bar can be easily corrected to an appropriate state with the best operability.

By the way, in the present embodiment, the locking projection 7b is provided on the inner peripheral surface of the handle 7, and the notch 4a is formed between the stoppers 4 and 4 provided at the end of the main body 3 to make the shower hook 1 In the assembled state, the locking projection 7b of the handle 7 can be moved only within the range of the notch 4a between the stoppers 4 and 4. With this configuration, the rotation angle of the handle 7 can be restricted within a predetermined range. Therefore, if the range of the notch 4a is set so that the rotation angle of the handle 7 is set to the minimum necessary for the advance amount of the pusher 5 to stop the shower hook 1, the handle 7 will be more than necessary. There is no risk of applying excessive tightening force to the pusher 5 by rotating it.

As shown in FIG. 2, the hook portion 2 and the main body portion 3 are connected by screwing a bolt 12 into a nut member 13 attached to the main body portion 3. In the drawings, 11 is a cosmetic cap for closing the opening of the hook portion 2 into which a screwdriver or the like is inserted to rotate the bolt 12.

Depending on the usage of the shower hook 1, it may be desired to change the angle of the hook portion 2 with respect to the main body portion 3. In this embodiment, an angle adjustment between the hook portion 2 and the main body portion 3 is possible by the following mechanism. That is, as shown in FIGS. 2 and 5 (A), on the hook portion 2 side of the connection portion between the hook portion 2 and the main body portion 3, a joint surface J having a large number of radial V-shaped grooves radially formed on the surface thereof. _The ring-shaped joint member 14 having 1 is attached. On the other hand, a ring-shaped joint member 15 having a joint surface J _{2 in} which a similar V-shaped groove is partially formed, as shown in FIGS. Mounting. Then, between the former ring-shaped joint member 14 and the hook portion 2, and between the latter ring-shaped joint member 15 and the main body portion 3, appropriate anti-rotation means are provided. Further, as shown in FIG. 2, a spring 16 is compressed and mounted between the main body 3 and the ring-shaped joint member 15 mounted on the main body 3, and the hook 2 is attached to the main body 3 by a bolt 12. When assembled, the former joint surface J ₁ of the ring-shaped joint member 14 and the latter joint surface J _{2 of} the latter ring-shaped joint member 15 are engaged with the V-shaped groove provided in each spring 16 It is configured to be closer to the urging force of.

With the above configuration, when the main body 3 is fixed to the slide bar or the like and the hook 2 is given a rotational force larger than the predetermined value, the ring-shaped joint member 15 on the main body 3 side urges the spring 16. It is possible to move the hook portion 2 backward by a slight amount, and rotate the hook portion 2 by one mesh of the V-shaped groove. If the force is further applied, it is possible to rotate the hook portion 2 by the number of two V-shaped grooves engaged with each other or more.

The embodiments of the present invention are not limited to the above. For example, as the detent structure between the connecting bush 6 and the handle 7, a spline structure can be adopted in addition to the serration structure. Further, it may be possible to adopt a key structure, but in this case, it becomes necessary to consider that it is difficult to adjust the angle of the handle. Besides, the present invention does not prevent appropriate modifications according to the embodiments.

[0022]

[Effect of device]

 In the slide shower hook according to the present invention, the rotatable angle of the handle is regulated by the stopper for preventing the connecting bush interposed between the pusher for pressing the slide bar and the handle from falling off the main body. Therefore, there is no danger of applying excessive tightening force. Therefore, wear and fatigue are less likely to occur in each part of the shower hook, and it is possible to manufacture the entire shower hook with a synthetic resin having low durability.

Further, when the handle is rotated, the pusher in the main body does not move forward / backward at the screw-fitting portion with the connecting bush, and the handle itself does not move forward / backward, so there is no externally accessible portion. As a result, the usage condition looks good and there are fewer restrictions on the design.
