  EMBODIMENT OF THE INVENTION The form for implementing the antifouling mirror for bathrooms which concerns on this invention is demonstrated below with reference to drawings based on an Example.

(Example)
An embodiment of a bathroom antifouling mirror according to the present invention will be described with reference to FIGS. As shown in FIG. 1A, the bathroom antifouling mirror 1 of this embodiment has a hydrophilic added film 3 attached to the surface of the mirror body 2.

  The hydrophilic added film 3 has various configurations, and an example is shown in FIG. The film 3 shown in FIG. 1 (b) has a base material 6 formed of a resinous transparent thin film, a hydrophilic layer 7 provided on the surface of the base material 6, and an adhesive provided on the back surface of the base material 6. And a layer 8.

  As the hydrophilic layer 7, a well-known hydrophilic material such as a layer made of a material having a hydroxyl group, a photocatalyst layer, or a layer having irregularities on the surface is used. The adhesive used for the adhesive layer 8 is an adhesive such as acrylic urethane, urethane, or acrylic.

  As shown in FIG. 2A, the end face of the film 3 is obliquely chamfered with respect to the main surface 11 of the film 3, and the end face of the film 3 has a slope shape. A slope 12 (referred to as a “chamfered slope”) 12 formed by such oblique chamfering is provided so as to be continuous with the chamfered slope 13 of the mirror body 2.

  The chamfered slope 13 of the mirror body 2 is formed by obliquely chamfering a part of the vertical surface 10 at the end surface around the mirror body 2. The thickness t1 of the mirror body 2 is, for example, about 5 mm.

  The thickness t2 of the film 3 is, for example, about 100 μm. The angle α of the oblique chamfering with respect to the main surface 11 of the film 3 is, for example, about 40 ° to 70 °, and the horizontal width w of the chamfered slope 12 is preferably 200 μm or less.

  In order to chamfer the film 3 in this way, the end surface around the mirror body 2 is chamfered first to form a chamfered slope 13, the film 3 is attached to the surface of the mirror body 2, and the mirror 3 is then mirrored. The oblique chamfering of the film 3 is performed so that the slope becomes a continuous slope according to the angle of the chamfered slope 13 of the main body 2.

  Alternatively, the film 3 may be chamfered in advance, or the peripheral end surface may be formed into a sloped shape when the film 3 is manufactured, and the film 3 may be attached to the mirror body 2 that is chamfered separately. Alternatively, the film 3 and the mirror body 2 may be obliquely chamfered simultaneously (continuously) after the film 3 is attached to the mirror body 2.

  As described above, when the end surface around the film 3 is formed as the chamfered slope 12 continuously to the chamfered slope 13 around the mirror body 2, as shown in FIGS. 1 (a) and 2 (b), Around the mirror body 2, a chamfered slope 12 of the film 3 and a chamfered slope 13 of the mirror body 2 positioned so as to surround the outside are formed in a plan view.

  The corners 14 at the four corners of the mirror body 2 are cut off linearly in plan view, leaving a chamfered slope 13, and a cut-off surface 15 is formed as shown in FIGS. 2 (b) and 3 (a). Yes. The cut-off surface 15 includes a chamfered slope 16 and a vertical surface 17.

  Corresponding to the corners 14 at the four corners of the mirror body 2, the corners 20 at the four corners of the film 3 are also cut off in a straight line in plan view, leaving the chamfered slope 12, and FIG. As shown to 3 (a), the cut-off surface 18 is formed.

  The cut-off surface 18 of the corner 20 of the film 3 is also formed as a chamfered inclined surface having a gradient with respect to the main surface 11, similarly to the other chamfered inclined surfaces 12 of the film. When the corner portion 21 of the bathroom antifouling mirror 1 is viewed from the front, the cut-off surface 18 of the film 3 is formed in a trapezoidal shape as shown in FIG.

  The corner 20 of the film 3 is not linear, but may be cut in an arc shape in plan view to form a cut surface 22 as shown in FIG.

  Thus, even if the corner portion 20 of the film 3 is cut into an arc shape, the cut surface 22 is formed as an inclined surface having a gradient with respect to the main surface 11. The cut-off surface 22 of the corner 20 of the film 3 has a substantially fan shape in a plan view as shown in FIG. 4A, and a substantially fan shape in a front view as shown in FIG. 4B. Yes.

(Function)
The operation of the bathroom antifouling mirror 1 having the above configuration will be described. The configuration shown in FIG. 5A is a comparative example, and the film 3 is added to the upper surface of the mirror body 2, but the chamfered slope 12 is not formed on the end surface around the film 3, and the end surface Is a vertical surface 25.

  If the end surface of the film 3 is formed as the vertical surface 25 as in this comparative example, the user's finger or other object may be caught, and if the finger is caught, it will affect the end surface. Since the force acts as a turning force of the film 3, the film 3 is turned from its end surface, which causes a problem that it is easily peeled off.

  On the other hand, in the bathroom antifouling mirror 1 according to the present invention, the chamfered slope 12 having a gradient is formed on the end surface around the film 3, so that the user's finger and other objects are chamfered slopes. The film 3 is difficult to be caught by the chamfered slope 12 and hardly peeled off.

  In the bathroom antifouling mirror 1 according to the present invention, the film 3 is hydrophilic, and the contact angle of water droplets to the main surface 11 of the film 3 (the angle formed by the water droplets and the main surface 11) is small. The water droplets on the surface 11 spread flat and thin, are easy to dry, and water is easily removed. As a result, not only antifogging properties can be obtained, but also scar marks, dirt, mold and the like caused by residual water are less likely to occur.

  In particular, the water remaining near the end face around the film 3 tends to flow down along the chamfered slope 12 formed on the end face around the film 3. Accordingly, in the vicinity of the end face around the film 3, residual water is hardly generated on the surface of the film 3, and dirt traces, dirt, mold, and the like are hardly generated.

  FIG. 5B is another comparative example, but as shown in FIG. 5, the corner 20 of the film 3 is not cut off at the corner 14 of the mirror body 2 (see FIG. 2B). These are formed at right angles in a plan view and protrude from the corners 14 of the mirror body 2. The film 3 having such a configuration is easily turned off from its corners.

  On the other hand, in the bathroom antifouling mirror 1 according to the present invention, the corners of the film 3 are cut off at the corners 14 of the mirror body 2 as shown in FIGS. Since the mirror 3 does not protrude from the corner portion 14 of the mirror body 2, the film 3 is difficult to turn from the corner portion 20.

  Further, according to the film 3 of the present invention, as shown in FIG. 2B, the cut-off surface 18 having a slope is also formed in the corner portion 20 of the film 3, so that a human finger or the like is scratched. The film 3 is difficult to turn over, and the film 3 is difficult to turn over from the corner 20 and is difficult to peel off from the corner 20.

  As mentioned above, although the form for implementing the antifouling mirror for bathrooms concerning this invention was demonstrated based on the Example, this invention is not limited to such an Example, and is described in a claim It goes without saying that there are various embodiments within the scope of technical matters.

  Since the antifouling mirror for bathrooms according to the present invention is configured as described above, it can be applied not only to mirrors for bathrooms but also to mirrors for bathrooms used in the field of housing equipment, etc. It can also be widely applied to mirrors used in, for example.
