FIG. 2 is a perspective view showing a shower hook as an embodiment of the present invention.
FIG. 3 is a side sectional view of a shower hook as an embodiment of the present invention.
FIG. 4 is a side sectional view of the shower hook of FIG. 3, which has a shallower cross-sectional depth than that of FIG.
The shower hook 1 includes a bracket portion 5 attached to the wall surface 131a (the wall surface of the first wall panel 131 in FIG. 1) and an arm 6 having one end side rotatably connected to the bracket portion 5 in the lateral direction. Has been done. A holding portion 7 for holding the shower head 3 (FIG. 1) is provided on the other end side of the arm 6.

The bracket portion 5 has a bracket assembly 9 in which ribs 8 are provided vertically and horizontally, and a substantially upper half portion of the bracket assembly 9 is covered with a bracket cover member 10.
The bracket portion 5 is a portion of the base portion 11 having a surface portion along the wall surface 131a, and is attached to the wall surface 131a by a screw or the like. The base portion 11 is a member that constitutes a portion of the bracket assembly 9.
The bracket assembly 9 has a shaft for connecting the arm 6 to the bracket portion 5 so as to be rotatable in the lateral direction. The shaft is composed of a substantially tubular hollow shaft body 13 that rises upward from the base portion 12 that occupies the lower part of the bracket assembly 9. The position of the hollow shaft body 13 which is the shaft is set so that the direction of the central axis X is the vertical direction (hence, parallel to the wall surface 131a).

The base portion 12 and the hollow shaft body 13 are integrally formed to form a shaft structure 14. The bracket assembly 9 is configured by fitting the shaft structure 14 to the bracket assembly main body 15 which will be described later with reference to FIG. That is, the bracket assembly main body 15 and the shaft structure 14 are fitted so that the hollow shaft body 13 of the shaft structure 14 fits into the lower shaft hole 13a and the upper shaft hole 13b of the bracket assembly main body 15.

On the other hand, in the arm 6, a substantially upper half portion and a tip end side portion of the arm assembly 17 in which ribs 16 are provided vertically and horizontally are covered with an arm cover member 18.
A shaft hole 19 that rotatably fits into the hollow shaft body 13 of the bracket assembly 9 is provided in a portion of the arm assembly 17 that protrudes toward the bracket portion 5 from the arm cover member 18. The shaft hole 19 of the arm assembly 17 and a portion around the shaft hole 19 are connecting portions 20 to which the arm 6 is rotatably connected in the lateral direction by the hollow shaft body 13 of the bracket portion 5. The center of the shaft hole 19 of the connecting portion 20 is located on the central axis X of the hollow shaft body 13 of the bracket assembly 9.
A holding portion 7 is provided on the other end side so as to be rotatable in the vertical direction with respect to one end side on which the connecting portion 20 of the arm 6 is formed.

In the shower hook 1 of the present embodiment, the connection portion from the base portion 11 which is the end portion of the bracket portion 5 on the wall surface 131a side to the end portion on the arm 6 side (specifically, the center position of the connection portion 20 shaft hole 19 of the arm 6). The length from the connection portion 20 (specifically, the center position of the shaft hole 19), which is the end portion of the arm 6 on the bracket portion 5 side, to the tip portion, which is the end portion on the holding portion 7 side. Shorter than that.
In other words, the length from the connection portion 20 (center of the shaft hole 19) on one end side of the arm 6 to the tip side (tip side on which the holding portion 7 is provided) is fixed to the wall surface 131a of the bracket portion 5. It is longer than the length from the base portion 11 which is a portion to the connecting portion 20 (center of the shaft hole 19) of the arm 6.
Therefore, if the arm 6 is operated by touching the tip end side of the arm 6 when the arm 6 is rotated in the lateral direction, the arm length in the rotating operation becomes relatively long, and the arm 6 is rotationally displaced in the lateral direction with a small operating force. Can be touched. Therefore, the operability regarding the position adjustment of the arm 6 in the lateral direction (left-right rotation direction) is excellent.

Further, the central axis X of the hollow shaft body 13 of the bracket portion 5 that rotatably connects the arm 6 is vertical. Therefore, the runout of the tip end side of the arm 6 in the lateral direction (left-right rotation direction) is along the horizontal plane, and there is no discomfort when the arm 6 is rotated in the lateral direction to adjust the position, and the operability is good.
Further, the arm 6 is attached to the bracket portion 5 so as to extend in a direction inclined downward from the direction perpendicular to the wall surface 131a (horizontal direction in this example). Since the arm 6 protruding from the wall surface 131a longer than usual is directed in the direction in which the tip is lowered in this way, it is easier for the user to use than when it is directed in the horizontal direction or in the direction in which the tip side is raised. Excellent for.

Next, the structure of the holding portion 7 on the tip end side of the arm 6 and the mounting portion thereof will be described.
The holding portion 7 is formed with a concave surface portion 7a having a relatively large diameter (loose curvature) on the tip side (upper side) corresponding to the tapered pipe portion connected to the shower hose 4 of the shower head 3. The holding portion 7 is substantially circular in side view, and the concave surface portion 7a is formed along the diameter direction of this circle. On the outside of the holding portion 7, the shaft body 21 (see FIG. 4) protrudes from each of the left and right positions (in FIGS. 3 and 4, the front side and the back side of the paper surface) corresponding to the center of the substantially circular shape. It is installed. Further, a boss 22 for restricting the rotation range is projected in parallel with the shaft body 21 at a position separated from the center of the shaft body 21 in a substantially circular shape by a predetermined distance.
A shaft hole 23 into which the shaft body 21 is rotatably fitted and an arc-shaped elongated hole for restricting the rotation range in which the boss 22 is fitted are rotatably fitted to the pair of protruding ribs 16a on the tip side of the arm assembly 17 of the arm 6. The rotation control hole 24 is provided. The holding portion 7 can rotate up and down about the axis of the shaft body 21 within a range in which the boss 22 can move in the rotation restricting hole 24 (shown by a two-dot chain line in FIG. 3).

The uneven ratchet tooth portion 25a of the ratchet mechanism 25 is formed on the curved surface of the outer periphery of the holding portion 7 facing the tip end side of the arm assembly 17. Further, a ratchet tooth stop portion 25b having an uneven portion corresponding to the ratchet tooth portion 25a is provided on the tip end side of the arm assembly 17. The ratchet tooth stop portion 25b protrudes from the urging portion 25c by an elastic body or the like behind the ratchet pawl portion 25b, and is elastically fitted to the ratchet tooth portion 25a. When the vertical rotation operation force of the user to the holding portion 7 via the shower head 3 becomes equal to or higher than a certain level, the ratchet tooth stopper 25b is elastically retracted and the ratchet tooth portion 25a is moved with respect to the ratchet tooth stopper 25b. The holding portion 7 is displaced relative to each other, and the holding portion 7 rotates step by step from one stable position of the ratchet mechanism 25 to the next stable position. The number of rotation stages is determined by the operation of the user, but the rotation range is restricted within the range in which the boss 22 is allowed to move in the rotation regulation hole 24.

Next, a mechanism for changing the direction of the shower hook 1 (arm 6 thereof) in the lateral direction will be described with reference to FIGS. 3 and 5.
FIG. 5 which is referred to in addition to FIG. 3 described above is a diagram illustrating a mechanism for changing the direction of the shower hook in the lateral direction as an embodiment of the present invention. FIG. 5 is a view showing the shower hook 1 in a plan view by breaking the upper part of the bracket portion 5 and the arm 6.
In FIG. 5, the corresponding parts with those in FIG. 3 are designated by the same reference numerals, and the description of the corresponding parts will be omitted as appropriate. In FIG. 5, the position when the arm 6 is rotated laterally from the position perpendicular to the wall surface 131a in a plan view is shown by a chain double-dashed line.

A ratchet mechanism 26 is also provided at a portion where the arm 6 is rotatably connected to the bracket portion 5 in the lateral direction.
The ratchet mechanism 26 includes a concavo-convex ratchet tooth portion 26a formed on the peripheral surface of the outer periphery of the hollow shaft body 13 facing the base end side of the arm assembly 17, and a ratchet tooth portion on the base end side of the arm assembly 17. It is configured to include a ratchet pawl portion 26b provided so as to face the 26a. The ratchet tooth stop portion 26b protrudes from the urging portion 26c by an elastic body or the like behind the ratchet pawl portion 26b, and is elastically fitted to the ratchet tooth portion 26a. When the user's left-right (lateral) rotational operation force on the arm 6 exceeds a certain level, the ratchet tooth stopper 26b is elastically retracted and the ratchet tooth portion 26a is displaced relative to the ratchet tooth stopper 26b. .. In the ratchet mechanism 26, the position of the ratchet tooth portion 26a formed on the outer periphery of the hollow shaft body 13 is fixed, and the position of the ratchet tooth stop portion 26b on the arm assembly 17 side moves. The arm 6 rotates step by step from one stable position of the ratchet mechanism 26 to the next stable position. The number of rotation stages is determined by the operation of the user, but the rotation range is regulated within a predetermined rotation angle by a mechanism unit (not shown).

Here, the connection mechanism between the bracket portion 5 of the shower hook 1 and the arm 6 will be described with reference to each of the above-described drawings together with FIG.
FIG. 6 is a view showing a sliding portion in the connection mechanism between the bracket portion of the shower hook and the arm according to the embodiment of the present invention, and is a perspective view of the bracket assembly main body 15 described above.
The bracket assembly main body 15 is provided with a lower shaft hole 13a and an upper shaft hole 13b through which the hollow shaft body 13 of the shaft structure 14 described with reference to FIG. 3 penetrates. The surface of the lower shaft hole 13a on the upper open end side constitutes a receiving surface 28 that faces and receives the lower surface sliding contact portion 27 on the lower surface side of the connecting portion 20 of the arm 6. That is, the receiving surface 28 is a surface portion on the bracket portion 5 side corresponding to the lower surface sliding contact portion 27 (see FIG. 4) on the arm 6 side in the connecting portion 20 which is a portion for connecting the arm 6 so as to be rotatable in the lateral direction. be.

The receiving surface 28 is provided with a sliding contact rib 29 in order to reduce friction due to sliding contact with the lower surface sliding contact portion 27, and the receiving surface 28 is inclined with respect to a horizontal plane. This inclination in this example is an inclination that descends forward in the front-rear direction, which is a direction vertically separated from the wall surface 131a when the bracket portion 5 is attached to the wall surface 131a on the base 11 side. The angle of inclination is relatively gentle, but due to this inclination, water does not easily stay in the gap between the upper surface side of the receiving surface 28, that is, the lower surface sliding contact portion 27 on the arm 6 side and the receiving surface 28, and drainage is possible. Excellent for. Further, the sliding contact ribs 29 are arranged as one ridge on each of the left and right sides of the lower shaft hole 13a on the receiving surface 28 so as to extend in the front-rear direction with a length exceeding the diameter dimension of the lower shaft hole 13a. .. Corresponding to the inclination of the receiving surface 28 as described above, the height of the sliding contact rib 29 from the receiving surface 28 is inclined so as to increase toward the front. Therefore, the upper surface of the sliding contact rib 29 is maintained horizontal even though the receiving surface 28 is inclined downward. Therefore, while adopting a structure in which the central axis X of the hollow shaft body 13 of the shaft structure 14 fitted to the bracket assembly main body 15 is parallel (substantially vertical) to the wall surface 131a, the arm 6 is moved in the left-right direction. Good operability is ensured without causing discomfort in the rotation operation.

According to the present embodiment described above, the following effects are achieved.
(1) The shower hook 1 of the present embodiment has a bracket portion 5 attached to the wall surface 131a and a holding portion 7 having one end side rotatably connected to the bracket portion 5 in the lateral direction and holding the shower head 3 on the other end side. The length from the end of the bracket portion 5 on the wall surface 131a side to the end on the arm 6 side is the end portion (connection portion 20) of the arm 6 on the bracket portion 5 side. It is shorter than the length from to the end on the holding portion 7 side.
In this configuration, the length from the connection portion 20 (center of the lower shaft hole 13a and the upper shaft hole 13b), which is the end portion of the arm 6 on the bracket portion 5 side, to the end portion (tip portion) on the holding portion 7 side is It is longer than the length from the base portion 11 which is the end portion of the bracket portion 5 on the wall surface 131a side to the end portion on the arm 6 side.
Therefore, if the arm 6 is operated by touching the tip end side of the arm 6 when the arm 6 is rotated in the lateral direction, the arm length in the rotating operation is long, so that the arm 6 can be rotationally displaced in the lateral direction with a small operating force. .. Therefore, the operability of the lateral position adjustment of the arm 6 (position adjustment related to the left-right rotation shown by the alternate long and short dash line in FIG. 5) is excellent.

(2) In the shower hook 1, a hollow shaft body 13 (direction of the central axis X in FIG. 3) for connecting the arm 6 to the bracket portion 5 so as to be rotatable in the lateral direction is vertically provided.
Therefore, the movement when the arm 6 is rotated in the lateral direction substantially draws a locus along the horizontal direction, and there is no sense of discomfort in the movement, which is convenient for the user.

(3) The shower hook 1 has a sliding contact rib on the receiving surface 28 on the bracket portion 5 side corresponding to the lower surface sliding contact portion 27 on the arm 6 side at a portion where the arm 6 is rotatably connected to the bracket portion 5 in the lateral direction. 29 is provided and the receiving surface 28 is inclined with respect to the horizontal plane.
Therefore, due to the inclination of the receiving surface 28, water is less likely to stay in the upper surface side of the receiving surface 28, that is, in the gap between the lower surface sliding contact portion 27 on the arm 6 side and the receiving surface 28, and the drainage property is excellent. Further, the lower surface sliding contact portion 27 and the receiving surface 28 do not come into direct contact with each other on the entire surface, but are slidly contacted with a limited contact surface with the sliding contact rib 29 interposed therebetween. Therefore, the frictional resistance of the sliding contact is reduced, and the arm 6 can be easily rotated in the lateral direction.

(4) In the shower hook 1, the arm 6 is inclined and extends so as to be lowered from the bracket portion 5 side toward the holding portion 7 side.
For this reason, the arm 6 projecting from the wall surface 131a longer than usual has its tip oriented in the descending direction, so that the user does not feel uncomfortable and is more convenient than when the arm 6 is oriented in the horizontal direction or in the upward direction. Excellent for.

(5) In the shower hook 1, the holding portion 7 holds the shower head 3 so as to be rotatable in the vertical direction.
Therefore, the holding portion 7 can rotate the shower head 3 in the vertical direction with respect to the arm 6 which itself can rotate in the lateral direction, and the direction of the shower head 3 can be adjusted in a wide range. It can be done and is easy for the user to use.

The present invention is not limited to the above embodiment, and the present invention includes modifications and the like within the range in which the object of the present invention can be achieved.
For example, in the above embodiment, the bracket assembly main body 15 of the bracket portion 5 supports the hollow shaft body 13 of the shaft structure 14 with shaft holes vertically separated from the lower shaft hole 13a and the upper shaft hole 13b, and also supports the hollow shaft body 13 of the shaft structure 14. Both shaft holes 13a and 13b are vertically separated from each other, and are configured to pivotally support the connecting portion 20 of the arm 6. However, the connection mode between the bracket portion 5 and the arm 6 is not limited to this. It can be sandwiched between the thick plate-shaped connecting portions, and the shaft holes of the protruding member on the bracket portion 5 side and the upper and lower connecting portions on the arm 6 side can be aligned and connected through the hollow shaft body 13. In addition to this, various aspects can be adopted.
