Description

  The present invention relates to a showerhead cover fixing structure.

  Conventionally, the following fixing structures for shower head covers are known. In FIG. 3, a shower face 100, which is an example of a “cover”, is fixed to the main body 106 side of the shower head 104 using screws 102. 4 is for fixing the shower face 108 itself to the main body 106 side by screwing. A male screw portion is engraved on the outer surface of the shower face 108, and this male screw portion is provided on the main body 106 side. A female threaded portion that is screwed with is engraved (there is a case where the male threaded portion is provided on the main body 106 side and the female threaded portion is provided on the shower face 108 side), and both are fixed (for example, Patent Document 1 and Patent Document). 2).

Japanese Utility Model Publication No. 5-9659 (FIG. 1) Japanese Patent Laid-Open No. 2001-220785 (FIG. 1)

  In the conventional first fixing structure described above, the screw 102 is exposed on the surface of the shower face 100, so the appearance of the shower head 104 is very poor. Further, the conventional second fixing structure cannot be used when a screw portion is not provided on the shower face 108 or the main body 106 side. In particular, if the shower face 108 has a perfect circle shape like the shower head 104 in FIG. 4, the orientation of the shower face 108 will not be a problem depending on the position at which the screw is tightened, but the rectangular shape in plan view has been increasing in recent years. For an elliptical shower face, the orientation of the shower face at the position where the screw is tightened becomes a problem. For example, it is very difficult to engrave the threaded portion so that the longitudinal direction of the shower face coincides with the longitudinal direction on the head portion side at the position where the screw is tightened.

  The present invention solves the above-described problems of the conventional shower head cover fixing structure, does not impair the beauty of the shower head, and is a screw portion for screwing the cover onto the cover itself or the main body side. It is an object of the present invention to provide a fixing structure that can fix the cover securely and firmly even when it is difficult to provide the cover.

  In order to solve the above problems, means taken by the present invention will be described below. The shower head cover fixing structure of the present invention is a shower head cover fixing structure for mounting a built-in component such as an inner to the shower head main body and fixing the cover to the main body. The shower head cover fixing structure is fixed to the main body and is also fixed to the built-in component (Claim 1).

  According to the present invention, since the screw is not attached, the appearance of the shower head is not impaired, and the orientation of the cover becomes a problem. Even in such a case, the cover can be securely and firmly fixed by engaging and fixing to the main body and the built-in components while corresponding the direction of the cover to the main body side.

  The “cover” referred to in the present invention includes a cover for fixing a separate shower face to the main body, and a cover having a shower face itself. “Built-in parts” include all the parts to be mounted on the main body of the shower head, in addition to the illustrated inner member and the like, as well as flow path members such as pipes. Examples of means for “locking and fixing” include “projections” and “concaves”. The “main body” of the shower head refers to all parts of the shower head except “cover” and “built-in parts”.

  Further, the built-in component may be applied to a part exposed outside the shower head.

  By locking and fixing the cover to the built-in component, the adhesion between the cover and the built-in component is enhanced. Here, when the built-in component is exposed to the outside of the shower head, if a gap is generated between the cover and the built-in component, there is a risk that the appearance of the shower head may be impaired. Since the adhesiveness with the built-in parts is enhanced, the possibility that such a gap is generated can be reduced.

  Further, the locking direction between the cover and the main body may be different from the locking direction between the cover and the built-in component (claim 3).

  In this way, even if the shower head is accidentally dropped, for example, the cover and the main body are locked in the shower head vertical direction, and the cover and the built-in component are locked in the horizontal direction of the shower head. By locking in different directions, it is possible to make it difficult to release all the locking even when a force is applied to the cover from a specific direction. “Different directions” includes not only making the directions different from each other in the orthogonal direction as in this example but also making them different at other angles. “Locking direction” means a moving direction of means such as locking protrusions and locking holes when they are fixed / released.

  Since the present invention is configured as described above, a cover that is difficult to fix to the main body by providing a screw part such as a rectangular cover is securely and firmly fixed to the main body without impairing the beauty of the shower head. can do. In particular, in the fixing structure according to the second aspect, the adhesion between the cover and the built-in component can be enhanced, so that the aesthetic appearance can be further improved. In the fixing structure of claim 3, the cover is not easily detached even when a strong force is applied such as when dropped, and the cover can be fixed more securely and firmly.

  Next, an embodiment of the shower head cover fixing structure of the present invention will be described in detail with reference to the drawings.
