The inclination angle β between the hole and the back surface of the base plate is different.

  Hereinafter, although the shower hook of this invention is demonstrated, referring drawings, the shower hook of this invention is not limited to the aspect shown by drawing.

  FIG. 1 is an exploded perspective view for explaining a main part of the shower hook of the present invention. The shower hook 1 of the present invention includes a base plate 3 and a shower hook body 5 that is rotatably attached to the base plate 3. As shown in FIG. 2, the shower hook main body 5 includes a back surface portion 7 and a pair of grip portions 9 and 9 formed so as to protrude from the back surface portion 7 to the front side. The back surface portion 7 and the pair of grip portions 9, 9 form a through hole 15 for holding a shower head having an opening 11 on the front side and openings 13a, 13b in the vertical direction. 3 is a cross-sectional view taken along the line AA of the shower hook 1 of FIG. The through-hole 15 bends in a U shape with respect to the back surface 17 of the base plate 3, and penetrates the first through-hole 21 a penetrating from the bent portion 19 to the one opening 13 a and the bent portion 19 to the other opening 13 b. The second through hole 21b is formed in communication. The shower hook 1 of the present invention is characterized in that an inclination angle α formed by the first through hole 21a with the back surface 17 of the base plate 3 is different from an inclination angle β formed by the second through hole with the back surface of the base plate. In order to simplify the description, the means for fixing the shower hook body 5 and the base plate 3 are not shown in FIGS.

  The inclination angles α and β formed by the first through hole 21a and the second through hole 21b with the back surface 17 of the base plate 3, respectively, are such that the central axes of the first through hole and the second through hole intersect with the back surface 17 of the base plate 3. It is an angle to do. The central axis of the first through hole 21a is an axis connecting the center of the maximum inscribed circle inscribed in the opening 13a of the first through hole 21a and the center of the maximum inscribed circle inscribed in the opening of the bent portion 19. . The central axis of the second through hole 21b is an axis connecting the center of the maximum inscribed circle inscribed in the opening 13b of the first through hole 21b and the center of the maximum inscribed circle inscribed in the opening of the bent portion 19. . The back surface 17 of the base plate 3 is preferably a flat surface from the viewpoint of being easily attached to the wall surface of the bathroom. The inclination angles α and β have a positive sign from the back surface of the base plate toward the shower hook main body.

  The absolute value (| α−β |) of the difference between the inclination angle α and the inclination angle β is preferably 5 degrees or more, more preferably 10 degrees or more, and preferably 35 degrees or less. 30 degrees or less is more preferable, and 20 degrees or less is more preferable. This is because if the absolute value of the difference in tilt angle is less than 5 degrees, the magnitude of the change in the angle at which the shower head is held is insufficient. This is because if the difference in inclination angle exceeds 35 degrees, the change in angle is too large, and it becomes difficult to maintain the ease of use and stability of the shower head.

  The inclination angle α formed by the first through hole 21a with the back surface 17 of the base plate 3 is preferably −5 degrees or more, more preferably 0 degrees or more, preferably 10 degrees or less, and preferably 5 degrees or less.

Further, the length h1 of the first through hole is preferably 45 mm or less, more preferably 40 mm or less, and further preferably 35 mm or less. If the length h1 of the first through hole is more than 45 mm, the length of the first through hole is too long, and it becomes difficult to insert and remove the shower head from the shower hook. In addition, the shower hook main body becomes large, which causes a cost increase.

  The length h2 of the second through hole having the inclination angle β of 5 degrees to 30 degrees is preferably 10 mm or more, more preferably 20 mm or more, and further preferably 25 mm or more. If the length h2 of the second through hole is less than 10 mm, the length of the second through hole is too short, and it becomes difficult to stably hook the shower head. Further, the length h2 of the second through hole is preferably 45 mm or less, more preferably 40 mm or less, and further preferably 35 mm or less. If the length h2 of the second through hole is more than 45 mm, the length of the second through hole is too long, and it becomes difficult to insert and remove the shower head from the shower hook. In addition, the shower hook main body becomes large, which causes a cost increase.

  As shown in FIG. 3, the length h <b> 1 of the first through hole extends from the front edge of the first through hole opening 13 a to a straight line that passes through the bent portion 19 perpendicular to the back surface 17 of the base plate 3.
