Description

  The present invention relates to a mirror mounting structure for a mirror cabinet, and more particularly to a technique for preventing the mirror from rattling and dropping with respect to a substrate to which the mirror is mounted.

  2. Description of the Related Art Conventionally, there has been known a mirror mounting structure for a mirror cabinet in which a mirror is attached to a substrate disposed on the front surface of a mirror cabinet of a vanity with a mirror press mounting member (see, for example, Patent Document 1).

  As an example, as shown in FIG. 5, for example, the mirror locking portion 2 provided on the front surface of the mirror press 6 is locked to the edge 1a of the mirror 1, and the elastic deformation provided on the rear portion of the mirror press 6 is possible. A simple hook portion 5 is passed through a through hole 4 provided in the substrate 3 and engaged with the back surface 3 a of the substrate 3, so that the mirror 1 is pressed and attached to the substrate 3.

  However, the thickness E of the mirror 1 and the thickness F (thickness) of the substrate 3 may vary depending on product specifications and the like. For example, when the thickness E of the mirror 1 is reduced from 5 mm to 3 mm, it is common. When the mirror retainer 6 is used, a gap 11 between the back surface 3a of the substrate 3 and the projection 17 for preventing the hook portion 5 is widened. For this reason, for example, the mirror 1 is transported from the factory to the site with the substrate 3 attached. In this case, there is a problem that the backlash in the front-rear direction occurs in the mirror 1 due to vibration during transportation. Therefore, in the past, a new mirror retainer having a shape that prevents the mirror retainer 6 from being detached from the substrate 3 in accordance with the thickness E of the mirror 1 and the thickness F of the substrate 3 and that can prevent backlash in the front-rear direction. 6 is manufactured individually, and the manufacturing cost is high.

Furthermore, in order to prevent the mirror retainer 6 from coming off due to vibration during transportation, the hooking margin 12 of the hook portion 5 with respect to the substrate 3 may be increased. In this case, the hook portion 5 is inserted into the through hole 4 of the substrate 3. It becomes difficult to pass. Therefore, in order to facilitate the attachment work of the mirror retainer 6, the hook allowance 12 of the hook portion 5 cannot be made too large. As a result, the mirror retainer 6 may come out of the through hole 4 due to vibration and the mirror 1 may fall. there were.

  The present invention has been invented in view of the above-described conventional problems, and can reliably prevent the rattling and dropping of the mirror during vibration during transportation and the like, and can facilitate the mounting operation of the mirror presser. The object is to provide a mirror mounting structure for a mirror cabinet that can be used in common even if the thickness of the mirror changes.

  In order to solve the above-mentioned problems, the present invention is a mirror mounting structure for a mirror cabinet in which the mirror 1 is attached to a substrate 3 disposed on the front surface of the mirror cabinet body by means of a mirror pressing mounting member 7. The mounting member 7 is an elastically deformable hook portion 5 that passes through the mirror locking portion 2 that is locked to the edge 1 a of the mirror 1 and the through hole 4 provided in the substrate 3 and is locked to the back surface 3 a side of the substrate 3. And an insertion ring 8 that holds the hook portion 5 at a position away from the back surface 3a of the substrate 3 by being inserted into the hook portion 5 from the back surface 3a side of the substrate 3. The insertion ring 8 is configured to face the back surface 3 a of the substrate 3.

  By adopting such a configuration, the mirror locking portion 2 of the mirror retainer 6 is drawn toward the substrate 3 by the insertion ring 8, so that backlash in the front-rear direction of the mirror 1 is prevented as much as possible even when vibration is applied during transportation. become able to. Moreover, since the insertion ring 8 is disposed opposite to the back surface 3 a of the substrate 3, it is possible to prevent the mirror holder 6 from coming off by the insertion ring 8, thereby preventing the mirror 1 from dropping due to vibrations, and to the substrate 3. The hooking portion 12 of the hook portion 5 can be reduced, and the mirror holder 6 can be easily attached. Further, even when the thickness of the mirror 1 or the thickness (wall thickness) of the substrate 3 is reduced, the mirror ring 6 can be prevented from rattling and fall off by the insertion ring 8, so that the mirror holder 6 is used as a common part. Can be used.

  The hook portion 5 is formed between a pair of elastically deformable arm portions 14 projecting from the rear end side of the shaft portion 13 of the mirror presser 6 to the left and right sides, and between each arm portion 14 and the shaft portion 13. Left and right insertion spaces 18, and the insertion ring 8 includes a gripping piece 15 to be gripped by a finger and a pair of insertion pieces 16 respectively inserted into the left and right insertion spaces 18. The pair of insertion pieces 16 are formed such that the insertion portion 9 into the insertion space 18 is curved inward from the substrate facing portion 10 disposed opposite to the back surface 3a of the substrate 3. In this case, the insertion piece 16 of the insertion ring 8 does not fall out of the insertion space 18 due to the bending of the insertion piece 16, and the insertion ring 8 has a spring property. Even after plugging Without simply disengaged, it is possible to reliably prevent dropping mirror 1.

  Further, the grip piece 15 of the insertion ring 8 is preferably bent with respect to the insertion direction of the insertion piece 16. In this case, the insertion piece 16 can be easily inserted into the insertion space 18 by grasping the grip piece 15 with a finger. Therefore, the workability at the time of attaching the insertion ring 8 is further improved.

  The present invention uses an insertion ring separate from the mirror holder to hold the mirror holder hook part away from the back surface of the substrate, thereby preventing backlash in the front-rear direction of the mirror even when vibration is applied during transportation. It is possible to prevent as much as possible, and by placing the part other than the insertion part into the insertion space of the insertion ring opposite to the back side of the substrate, it is possible to prevent the insertion of the mirror holder from being prevented and to prevent the insertion of the mirror holder. It becomes easy to attach. Furthermore, even if the thickness of the mirror or the thickness of the substrate changes, the mirror holder can be used in common, so that the mirror holder and the thickness of the substrate are matched to the thickness of the mirror and the thickness of the substrate as in the past, With a shape that can prevent backlash in the front-rear direction, there is no need to manufacture a new mirror holder, and the cost of the mirror holder can be reduced.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  The mirror press attachment member 7 of this embodiment is used for pressing and attaching the mirror 1 to the substrate 3 in the mirror cabinet of the vanity.

  The substrate 3 is made of a synthetic resin molded product having a predetermined thickness F as shown in FIGS. The substrate 3 is formed with a through hole 4 through which a hook portion 5 of a later-described mirror presser 6 passes.

  The mirror retainer mounting member 7 includes a mirror retainer 6 and an insertion ring 8.

  In the following example, a structure in which the lower edge 1a of the mirror 1 is pressed and attached will be described.

  As shown in FIGS. 3 (a) and 3 (b), the mirror retainer 6 of this example is obtained by bending a leaf spring material into an L shape, and is a mirror locking portion that is locked to the edge 1a of the mirror 1 by the bent portion. 2 is formed, and a shaft portion 13 with a hook portion 5 having a hook shape is formed by a flat plate portion.

  The hook-shaped hook portion 5 includes a pair of left and right arm portions 14 projecting from the rear end of the shaft portion 13 to the left and right sides, and each arm portion 14 can be elastically deformed in the expanding and contracting direction indicated by the arrows in FIG. It has become. Here, the rear end side of the shaft portion 13 is formed thin, and the left and right arm portions 14 are inclined in a direction away from the shaft portion 13 from the base end portion connected to the rear end of the shaft portion 13 toward the distal end portion 14b side. Each arm portion 14 has an inclined portion 14a, the tip portion 14b of each arm portion 14 extends substantially parallel to the shaft portion 13, and the space between the tip portion 14b of each arm portion 14 and the shaft portion 13 serves as an insertion space 18, respectively. ing. Further, a protruding protrusion 17 is provided on the outer surface portion of the boundary between the distal end portion 14b and the inclined portion 14a of each arm portion 14 and is located behind the insertion space 18. Here, when the hook portion 5 is pushed into the through hole 4 of the substrate 3, the left and right arm portions 14 are elastically contracted (in the state shown in FIG. 3C), and the outer dimension C between the retaining projections 17 is the substrate. 3 is equal to or smaller than the inner dimension A of the through hole 4 (FIG. 2) (C ≦ A), the hook part 5 can pass through the through hole 4, and the arm part 14 is expanded after passing ( 3 (a)), the outer dimension B between the retaining projections 17 becomes larger than the inner dimension A (FIG. 2) of the through hole 4 (B> A), and does not come out of the through hole 4. It becomes a structure.

  On the other hand, the insertion ring 8 has both a backlash prevention function and a dropout prevention function of the mirror 1 by holding the hook portion 5 of the mirror retainer 6 away from the back surface 3 a of the substrate 3. As shown in FIG. 4, the insertion ring 8 of this example is formed by bending a wire material having a spring property into a substantially U shape, and its head portion is a grip piece 15 that is gripped by hand, and both leg portions are as described above. The insertion piece 16 is inserted into the insertion space 18 of the hook portion 5. Here, the gripping piece 15 is bent at a substantially right angle with respect to the insertion direction of the insertion piece 16 so that it can be easily gripped with a finger. Further, the left and right insertion pieces 16 are formed symmetrically, and an intermediate portion of each insertion piece 16 is an insertion portion 9 that is curved inward. It becomes the board | substrate opposing site | part 10 which curved to the direction. In a state where the insertion portion 9 of the insertion piece 16 is inserted into the insertion space 18 of the hook portion 5, the substrate facing portions 10 on both the upper and lower sides are opposed to the back surface 3 a of the substrate 3, and in this state, the insertion piece Reference numeral 16 is arranged at a position closer to the front side (the back surface 3a side of the substrate 3) than the protruding convex portion 17 of the hook portion 5.

  Next, when the mirror 1 is attached to the substrate 3, the mirror locking portion 2 of the mirror holder 6 is aligned with the lower edge 1a of the mirror 1 from the front indicated by the arrow D in FIGS. While, the hook portion 5 of the mirror holder 6 is pushed into the through hole 4 of the substrate 3 from below the edge 1 a of the mirror 1. At this time, the left and right arm portions 14 of the hook portion 5 are elastically contracted (in the state shown in FIG. 3C) and pass through the through-hole 4 and then expanded (in the state shown in FIG. 1A). The protruding protrusion 17 of the portion 14 has a diameter larger than that of the through hole 4 and is in a state of preventing the through hole 4 from coming off. In this retaining state, the mirror 1 is likely to be loose in the front-rear direction due to the front-rear gap 11 between the back surface 3 a of the substrate 3 and the retaining projection 17.

  Thereafter, the right and left insertion pieces 16 of the insertion ring 8 are pressed inward with fingers from the back surface 3a side of the substrate 3 so as to straddle the shaft portion 13 of the mirror holder 6 and inserted into the left and right insertion spaces 18 from above. . At this time, by inserting the insertion portion 9 of the insertion piece 16 into the insertion space 18 as shown in FIG. 2, the substrate facing portions 10 that protrude outwardly on both the upper and lower sides respectively face the back surface 3 a of the substrate 3. As a result, the mirror retainer 6 does not come out of the through hole 4 of the substrate 3. Further, at this time, the insertion piece 16 is prevented from moving rearward by the inclined portion 14a (FIG. 2) of the arm portion 14, whereby the insertion piece 16 is forward of the retaining projection 17 in the insertion space 18 (substrate). 3 (on the back surface 3a side) 3 (the state shown in FIGS. 1A and 1B).

  Thus, the insertion ring 8 is inserted from the back surface 3 a side of the substrate 3 into the insertion space 18 provided on the hook portion 5 side that penetrates the through hole 4 of the substrate 3, and the hook portion 5 is moved away from the back surface 3 a of the substrate 3. By holding in this way, the front-rear direction gap 11 a (<gap 11) between the substrate 3 and the insertion ring 8 is narrowed, and as a result, the mirror locking portion 2 of the mirror holder 6 is made to move to the substrate 3 by the insertion ring 8. Since it is attracted to the side, it is possible to prevent backlash in the front-rear direction of the mirror 1 as much as possible even if vibration during transportation is applied.

  In addition, since the substrate facing portion 10 of the insertion ring 8 is disposed opposite to the back surface 3a of the substrate 3, the mirror holder 6 can be reliably prevented from coming off by the insertion ring 8, and thus the mirror 1 caused by vibration during transportation can be prevented. Can be prevented, and the hooking portion 12 of the hook portion 5 with respect to the substrate 3 can be reduced, so that the mirror holder 6 can be easily attached. That is, if the hooking allowance 12 of the hook part 5 is increased so that the mirror retainer 6 is not pulled out, it will be difficult to pass through the through hole 4 and hinder the attaching work of the mirror retainer 6. In this case, there is a problem that the hook portion 5 is easily pulled out of the through hole 4 due to vibration of transportation and the mirror 1 falls, but in the present invention, there is no such problem by using the insertion ring 8. The mirror holder 6 can be easily attached and the mirror 1 can be reliably prevented from falling.

  Further, even when the thickness E of the mirror 1 and the thickness F of the substrate 3 are reduced, the effect of preventing the backlash and dropping of the mirror 1 by the insertion ring 8 can be obtained. It can be used as a part. As a result, the new mirror retainer 6 is shaped so as to prevent the mirror retainer 6 from being detached from the substrate 3 in accordance with the thickness of the mirror 1 and the thickness of the substrate 3 as in the prior art, and to prevent backlash in the front-rear direction. It is not necessary to manufacture the mirror holder 6 and the cost of the mirror holder 6 can be reduced.

  In addition, since the insertion ring 8 is not pressed against the back surface 3a of the substrate 3, an excessive force is not applied to the substrate 3, and there is an advantage that the substrate 3 as a molded product can be protected.

  Moreover, in this example, since the insertion site | part 9 of the insertion piece 16 is curving inward, the insertion piece 16 does not fall out from the insertion space 18, Furthermore, the insertion ring 8 has spring property. Therefore, it does not easily come off after being inserted into the insertion space 18 of the mirror holder 6, and therefore the insertion ring 8 can be easily detached from the mirror holder 6 even when the mirror 1 is rattled due to vibration during transportation. There is an advantage that the mirror 1 can be more reliably prevented from falling.

  Further, in this example, the gripping piece 15 of the insertion ring 8 is bent at a substantially right angle with respect to the insertion direction of the insertion piece 16, so that the gripping piece 15 is grasped with a finger and the insertion piece 16 is inserted into the insertion space 18. It becomes easy and workability | operativity at the time of attachment of the insertion ring 8 becomes still better.

  In the above-described embodiment, the case where the mirror holding member 7 is attached to the lower edge 1a of the mirror 1 has been described, but the case where it is attached to the upper edge of the mirror 1 is also possible.
