JP 2002-364037 A (Claims, FIG. 1)

  However, although the thing of patent document 1 can change freely the height which latches a shower head, the height which set the shower hanger body which latches a shower head against the weight and water pressure of a shower head. Therefore, a strong spring force is required to securely hold. If such a strong spring force is provided, a large force is also required for the operation of pushing the lever member into the side surface of the shower hanger body in order to release the fixation. In addition, it is necessary to apply the force for releasing the fixing and the force for raising and lowering the hanger body in different directions. For this reason, if the shower hanger body is not grasped and operated, the lever member will be pushed. There is a risk of rotating or dropping rapidly. Further, since the spring member is accommodated in the outer position away from the slide bar, there is a problem that the protrusion of the hanger portion becomes large and obstructs.

  The present invention has been made in view of the above circumstances, and can operate the force for releasing the fixing of the shower hanger body and the force for raising and lowering in a direction that coincides with the operating force for releasing the fixing of the shower hanger body. To provide a shower head lifting support device that is small enough and does not cause the shower hanger body to rotate or slide down in the circumferential direction of the slide hanger even if the shower hanger body is not firmly grasped and operated. It is intended.

  In order to achieve the above object, a shower head lifting support device of the present invention comprises a slide rail and a shower hanger that is movably fixed to the slide rail, and the shower hanger includes the slide rail. A shower hanger body having a penetrating part to be inserted; a rail holding part provided on the shower hanger body for holding the slide rail; and a hook provided on one side of the shower hanger body for locking the shower head. The rail holding portion is disposed above and below the slide lock spring provided inside the shower hanger body and energizing the slide rail with a frictional force, and the slide lock spring inside the shower hanger body. Slide block movable relative to slide rail And a lever member that is connected to the slide block and protrudes to the outside of the shower hanger body, and the slide lock spring has a rail penetrating portion that penetrates to hold the slide rail. And, before compression at this rail penetration part, the slide rail is tightened by this rail penetration part by urging, and the rail penetration part is configured to be loosened to the slide rail by being compressed, (Claim 1).

  With such a configuration, the slide lock spring holds the slide rail and expands and contracts along the slide direction, and increases or decreases the frictional force of tightening. For this reason, it is easy to apply a small operating force to the upper lever member and push down the upper slide block.When the slide block is pushed down, the spring contracts and the frictional force decreases, and the shower hanger body is pushed downward. When the operating force is released, the shower hanger body is securely fixed to the slide rail without rattling. Similarly, when an operating force is applied to the lower lever member and the lower slide block is pushed up, the spring contracts and the frictional force decreases, the shower hanger body is pushed upward, and when the operating force is released, the shower hanger The main body is fixed to the slide rail.

  Further, in the shower head lifting support device according to the present invention, the rail holding portion includes a pair of fit blocks which are arranged above and below the slide block inside the shower hanger body and are slidably fitted on the slide rail. (Claim 2). In this case, it is preferable that the fit block is divided into two and is urged by a spring to be in close contact with the slide rail.

  In the shower head lifting support device of the present invention, it is preferable that at least the rail penetration portion of the slide lock spring is covered with a synthetic resin cover layer, and the cover layer is in sliding contact with the slide rail.

  In the shower head lifting support device of the present invention, it is preferable that the outer surface of the slide rail is cylindrical, and the shower hanger body is rotatable around the slide rail.

  As described in detail above, according to the shower head lifting support apparatus of the present invention, the following effects can be obtained because it is configured as described above.

  (1) According to the first aspect of the invention, the following excellent effects can be obtained.

  (1-a) Since the slide lock spring holds and tightens the penetration portion of the slide rail, the shower hanger body can be securely fixed to the slide rail without rattling.

  (1-b) Since the slide rail penetrates the slide lock spring, it is not necessary to provide a spring on the outside of the slide rail, and the lever member shower hanger can reduce the protrusion from the slide rail. It does not get in the way.

  (1-c) When the upper slide member is pushed down by the upper lever member, the spring contracts and the frictional force is reduced, the shower hanger body is pushed downward, and the lower slide member pushes the lower slide block. When pushed down, the spring contracts and the frictional force is reduced and the shower hanger body is pushed upward, so that the force for releasing the fixation of the shower hanger body and the force for raising and lowering can be applied in the same direction. For this reason, it is not necessary to hold and operate the shower hanger body firmly, and the shower hanger body can be fixed with a small operating force.

  (1-d) Since the slide lock spring has a frictional force that decreases in response to contraction, an appropriate frictional force is applied to the slide rail even when the lever member is operated. It can be moved smoothly.

  (2) According to the invention described in claim 2, since the pair of fit blocks are separated from each other and are in close contact with the slide rail, in addition to the above (1), when the shower hanger body is further raised and lowered, Moment action is unlikely to occur, and movement without shaking of the shower hanger body is guaranteed.

  (3) According to the invention described in claim 3, in addition to the above (2), since the rattle can be prevented by the biasing of the spring, the movement function of the shower hanger body does not deteriorate and the movement is free of rattling. Is guaranteed.

  (4) According to the invention described in claim 4, in addition to the above (1) to (3), the synthetic resin cover layer covering the slide lock spring is in sliding contact with the slide rail. When stopping, the frictional force can be increased and the slide rail can be securely locked, and when the shower hanger body is raised and lowered, the metal touch can be suppressed to prevent the generation of unpleasant noise.

  (5) According to the invention described in claim 5, in addition to the above (1) to (4), the shower hanger body can be further rotated in the circumferential direction of the slide rail. . And since operation force is small, even if it does not grasp and operate a shower hanger main body firmly, there is no possibility of rotating a shower hanger main body to the circumferential direction of a slide rail.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the best embodiment of the present invention will be described in detail with reference to the accompanying drawings.

First Embodiment FIG. 1 is a perspective view showing a state in which a shower head is hung on a shower head lifting support device according to a first embodiment of the present invention.

  The shower head lifting / lowering support device 100 includes a slide rail 10 having a handrail function fixed in a vertical direction on a wall surface of a bathroom and the like, and a shower hanger 20A fixed to the slide rail 10 so as to be movable up and down. .

  The slide rail 10 is formed of, for example, a stainless steel pipe material. The upper and lower ends are fixed to a pair of brackets 11 and 12 that are fixed to a wall surface of a bathroom in a vertical arrangement by screws, so that the slide rail 10 is provided in parallel with the wall surface of the bathroom. Then, cosmetic caps 13 and 14 are fitted on the upper and lower ends of the slide rail 10. The brackets 11 and 12 and the decorative caps 13 and 14 are formed of a molded product made of synthetic resin or aluminum die cast, for example.

  The shower hanger 20 </ b> A includes a shower hanger body 21 that holds a slide rail 10 and combines a symmetrical half body. The shower hanger body 21 has a box shape, and the slide rail 10 penetrates up and down. The shower hanger 20 </ b> A includes a shower hanger body 21 that forms a penetrating portion 21 b through which the slide rail 10 is inserted in the upper and lower surfaces by combining the split molded body 21 a. In the shower hanger body 21, a slide lock spring 22 is provided at the center, a pair of slide blocks 23 are provided above and below the slide lock spring 22, and a pair is provided above and below the slide block 23. The fitting block 24 is provided (see FIGS. 2 and 3).

  The slide lock spring 22 is means for urging and locking the friction force on the slide rail 10. The slide lock spring 22 includes a spring body 22a formed by opening two rail penetrating portions 22b, which are circular holes slightly larger than the diameter of the slide rail 10, in a long rectangular stainless steel thin plate, The cover layer 22c is made of a synthetic resin that covers the through portion 22b and has high durability. The cover layer 22c is formed of a soft synthetic resin and is covered on the spring body 22a by dipping or the like, for example. Furthermore, the slide lock spring 22 has a tongue-like tightening portion 22d (see FIG. 4).

  The tongue-shaped fastening portion 22d is provided with a short tongue piece projecting inwardly on one side of a circle when the rail penetrating portion 22b is machined into a long rectangular stainless steel thin plate. It is a portion that is bent at a substantially right angle with respect to the opening surface of the penetrating portion 22b and covered with the cover layer 22c. The presence of the tongue-like tightening portion 22d ensures a large contact area of the cover layer 22c with the slide rail 10, and increases the wear resistance of the cover layer 22c.

  Further, the slide lock spring 22 penetrates the slide rail 10 through the rail penetration portion 22 b, and the cover layer 22 c is in sliding contact with the slide rail 10. The slide lock spring 22 applies a force to both ends to bring the both ends closer to each other and reduce the bending angle of the “<” shape, thereby accumulating the return force, so that the slide rail 10 is inserted into the two rail penetration portions 22 b. After penetrating, by releasing the force applied to both ends, a frictional force is applied to the slide rail 10 so as to be held (see FIG. 3).

  In this way, the slide lock spring 22 is fixed to the slide rail 10 by applying a frictional force to the slide rail 10 at the upper and lower edges in the inclination direction of each rail penetrating portion 22b and applying force to both ends. When both ends approach each other and the bending angle of the “<” character decreases (compresses), the tightening of the slide rail 10 by the upper and lower edges in the inclined direction of each rail penetration portion 22 b is loosened. Has been.

  The slide block 23 is formed of, for example, a synthetic resin molded body, and protrudes from a block main body 23a having a shape in which a circular hole 23c for passing the slide rail 10 is provided in a thick rectangular plate, and both side surfaces of the block main body 23a. It consists of a provided locking projection 23b. The block main body 23a protrudes outside through the window portion 21c provided on the side surface of the shower hanger main body 21. This slide block 23 is capable of a stroke of, for example, 3 mm in the longitudinal direction of the slide rail 10 in the shower hanger body 21 (see FIGS. 2 and 3).

  The fit block 24 is accommodated in a partition partitioned by partition ribs 21h projecting inward from the inner surface of the shower hanger body 21 (see FIG. 3). The fit block 24 has a plurality of sliding contact ribs 24d parallel to the inner surface of the semicircular shape (in the drawing, five cases are shown), and is formed in two, and is urged by a spring 25 to be slid by the slide rail 10. It is closely attached to. In this case, as shown in FIG. 6, the spring 25 is accommodated in a state of projecting outward in the spring receiving recesses 24 a provided at two locations on the outer surface of the one fit block 24, and the other fit. Both fitting blocks 24 are urged by springs 25 by screwing fixing screws 24c passing through the molded body 21a of the shower hanger body 21 into screw holes 24b provided at two locations outside the block 24. It is in close contact with the slide rail 10.

  The fit block 24 can prevent rattling by the urging of the spring 25 and can reduce friction with the slide rail 10 by the sliding contact rib 24d provided on the inner surface when the shower hanger body 21 is lifted or lowered. Therefore, it can be raised and lowered smoothly. Thereby, the movement function of the shower hanger body 21 is not lowered and movement without rattling is ensured.

  The shower hanger 20A includes a total of four lever members 26 outside the shower hanger body 21 (see FIGS. 1 to 3 and 6). In this case, each lever member 26 has a square hole 26 a on one side surface, and this square hole 26 a is formed on the locking projection 23 b of the slide block 23 protruding from the window portion 21 c provided on the side surface of the shower hanger body 21. It is inserted. The lever member 26 is movable in the longitudinal direction of the slide rail 10 with a stroke of, for example, 3 mm within the window portion 21c (see FIG. 3).

  The shower hanger 20 </ b> A includes a hook 27 on one side of the outer surface of the shower hanger body 21. The hook 27 is supported at both ends by a pair of brackets 21d and 21d protruding from one side of the outer surface of the shower hanger body 21 (see FIGS. 1 and 2). Further, as shown in FIG. 6, the hook 27 is inserted so that both end faces are in close contact between the pair of brackets 21 d and 21 d, and both ends are fixed by set screws 28. The set screw 28 penetrates the hole 21e provided in each bracket 21d from the outside of each bracket 21d and is firmly tightened in the screw hole 27a provided in the end face of the hook 27. Since the set screw 28 and the bracket 21d are fitted in the relationship between the shaft and the bearing, the hook 27 can rotate integrally with the set screw 28 in a vertical plane.

  The hook 27 includes a shower head locking surface 27b that penetrates a tapered space having a large diameter on the upper side and a small diameter on the lower side in the center of the horizontal axis cylindrical body, and is open on the front side. The shower head SH can be inserted and hooked from above (see FIGS. 2, 3 and 6). The hook 27 is provided with a protrusion 27c at the center of the back surface, and this protrusion 27c is inserted into and engaged with a vertically long recess 21g provided in the shower hanger body 21, so that the swingable range in the vertical plane is limited. (See FIG. 3).

  Further, the hook 27 is provided with locking grooves 27d that are continuous in a wave shape when viewed from the side on both cylindrical surfaces sandwiching the protrusions 27b on the back surface, and in one trough portion of the locking grooves 27d, the shower hanger body 21 is provided. On the outer surface, a locking rib 21f having a substantially triangular vertical section projecting by a spring bias (not shown) is positioned and index-locked. The locking rib 21f can escape from one trough of the locking groove 27d and move to an adjacent trough (see FIG. 2).

  Therefore, when the hook 27 is swung in the vertical plane, the operator moves when the locking rib 21f biased by the spring from the inside moves from one valley portion to the other valley portion of the locking groove 27d. The tilt angle of the shower head SH can be adjusted by positioning with a split angle of 10 °, for example, while giving a click feeling to the hand.

  According to this embodiment, the shower hanger 20A is engaged with the slide rail 10 so as to be movable up and down and rotatable (see FIGS. 2 and 3).

  In order to change the inclination of the shower head SH, the inclination of the hook 27 for locking the shower head SH is changed. In this case, the inclination of the hook 27 can be changed by grasping the shower head SH. To change the height of the shower head SH, the height of the shower hanger 20A is changed. When the upper slide block 23 is pushed down, the inclination angle of the upper rail penetration part 22b of the slide lock spring 22 becomes smaller and the inclination angle of the lower rail penetration part 22b becomes smaller. Since the tightening force on the slide rail 10 is weakened and the pair of upper and lower fit blocks 24 are in close contact with the slide rail 10, the shower hanger 20 </ b> A is pushed downward without rattling. And if the force which pushes down the slide block 23 is cancelled | released, the shower hanger 20A will be reliably fixed to the slide rail 10 without backlash (refer FIG.3 (b)).

  Similarly, when the lower slide block 23 is pushed up, the inclination angle of the lower rail penetration part 22b of the slide lock spring 22 is reduced and the inclination angle of the upper rail penetration part 22b is reduced. The tightening force of the penetrating portion 22b against the slide rail 10 is weakened, and the shower hanger 20A is pushed upward without rattling. And if the force which pushes up the slide block 23 is cancelled | released, the shower hanger 20A will be reliably fixed to the slide rail 10 without rattling.

  According to the above embodiment, the direction of the shower head SH can be changed by re-fitting the shower head SH with the hook 27 and changing the direction, but the shower hanger 20A can be rotated around the slide rail 10. Therefore, convenience can be improved. In order to rotate the shower hanger 20A around the slide rail 10, an operating force is applied to the upper and lower slide blocks 23 to bring the upper and lower slide blocks 23 closer to each other, and the clamping force of the slide lock spring 22 to the slide rail 10 is increased. After loosening and rotating the shower hanger 20A around the slide rail 10, when the hand is released from the upper and lower slide blocks 23, the tightening force of the slide lock spring 22 is increased and the shower hanger 20A is fixed to the slide rail 10 again. .

  According to the embodiment, since the force for releasing the fixing of the shower hanger body 21 and the force for raising and lowering can be applied in the same direction, the operation force for releasing the fixing of the shower hanger body 21 is small and sufficient. Even if the shower hanger body 21 is not firmly grasped and operated, there is no possibility that the shower hanger body 21 is rotated in the circumferential direction of the slide rail or rapidly lowered.

Second Embodiment FIG. 7 is a cross-sectional view showing a fixed state of a second embodiment of the shower head lifting support device according to the present invention.

  In the shower hanger 20B of the second embodiment, the slide lock spring 29 and the slide block 30 are different from the slide lock spring 22A and the slide block 23 of the first embodiment, and other configurations are the same as those of the first embodiment. Is the same. For this reason, about the shower hanger 20B, another structure, an effect | action, and an effect attach | subject the code | symbol same as the corresponding component of the shower hanger 20A of 1st Embodiment, and abbreviate | omit description.

  This shower hanger 20B employs a slide lock spring 29 made of a compression coil spring. The slide lock spring 29 is formed by coating a compression coil spring made of a stainless steel wire with a synthetic resin. The slide lock spring 29 is coiled so that the coil inner diameter in a non-compressed state is slightly smaller than the outer diameter of the slide rail 10, for example, 1 mm, and is compressed so that the coil inner diameter is larger than the outer diameter of the slide rail 10. The diameter is increased and the slide rail 10 is penetrated inside. Accordingly, the slide lock spring 29 is wound around the slide rail 10 to urge and tighten the frictional force.

  The slide block 30 is formed in a shape that accommodates the winding end of the slide lock spring 29 in the recess. When the slide block 30 is pressed, the pressing force can be transmitted to the winding end of the slide lock spring 29 in the coil axis direction.

  According to the above embodiment, when changing the height of the shower hanger 20 </ b> A, when the upper slide block 23 is pushed down, the slide lock spring 29 is compressed and the coil inner diameter is expanded larger than the outer diameter of the slide rail 10. Therefore, the tightening force of the slide lock spring 29 on the slide rail 10 is weakened, and the pair of upper and lower fit blocks 24 are in close contact with the slide rail 10 without rattling, so that the shower hanger 20A is pushed downward without rattling. When the force that pushes down the slide block 23 is released, the pair of upper and lower fit blocks 24 are in close contact with the slide rail 10 without rattling, so that the shower hanger 20A is securely fixed to the slide rail 10 without rattling.

  Similarly, when the lower slide block 23 is pushed up, the slide lock spring 29 is compressed and the inner diameter of the coil is expanded larger than the outer diameter of the slide rail 10, so that the clamping force of the slide lock spring 29 against the slide rail 10 is increased. Is weakened, and the shower hanger 20A is pushed upward without rattling. And if the force which pushes up the slide block 23 is cancelled | released, the shower hanger 20A will be reliably fixed to the slide rail 10 without rattling.

  According to the second embodiment, the direction of the shower head SH can be changed by re-fitting the shower head SH to the hook 27 and changing the direction. However, the shower hanger 20A can be moved around the slide rail 10. Since it can be performed by rotating, the convenience can be improved. In order to rotate the shower hanger 20A around the slide rail 10, an operating force is applied to the upper and lower slide blocks 23 to bring the upper and lower slide blocks 23 closer to each other, and the tightening force of the slide lock spring 29 on the slide rail 10 is increased. After loosening and rotating the shower hanger 20A around the slide rail 10, when the hand is released from the upper and lower slide blocks 23, the tightening force of the slide lock spring 29 is increased and the shower hanger 20A is fixed to the slide rail 10 again. . The slide lock spring 29 is compressed by the slide block 23, the inner diameter of the slide lock spring 29 is increased, the tightening force of the slide lock spring 29 against the slide rail 10 is gradually loosened, and the inner diameter of the slide lock spring 29 is slid. When the diameter is increased larger than the outer diameter of the rail 10, the shower hanger 20 </ b> A can be moved and rotated.
