Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a mirror stopper for fixing the upper end of a mirror to a target wall such as a room wall.

(Prior Art) As shown in FIG. 9, the mirror B holds the lower end of the mirror B by a mirror stopper metal fitting A'which clamps the lower end of the mirror B, and then the mirror stopper metal clamp A which clamps the upper end of the mirror B is attached to the mounting target wall C. The screw body 1 screwed to the above is pushed down as a guide, and the upper end of the mirror B is held by the metal fitting A.

As a mirror stopper for fixing the upper end of the mirror, those shown in FIGS. 7 and 8 are known.

FIG. 7 shows a board a ₁ having a slot a ₆ for guiding the mounting screw ₁
A holding part a ₅ composed of a horizontal piece a ₂ and a vertical piece a ₃ is integrally formed on the upper end to form a metal fitting A, and a long hole formed in the base plate a _{1 of the} metal fitting A.
The substrate a ₁ is screwed to the target wall C with the screw 1 via the a _6, and the upper end of the mirror B is clamped between the packing material 3 hooked to the metal fitting A and the vertical piece a _3. ing.

FIG. 8 shows the packing material 3 in which the board a ₁ of the metal fitting A having the same structure as that of FIG.
The surface of the substrate a ₁ is covered with one half, and the covered portion 3 ′ and the metal fitting A
The upper end of the mirror B is clamped between the vertical piece a ₃ and the vertical piece a ₃ .

(Problems to be solved by the invention) However, in the above-mentioned conventional technique, the metal fitting A is lifted up on the hood due to being caught during cleaning of the mirror or the wall of an adjacent room, or the metal fitting A is gradually oscillated due to vibration of the wall due to opening / closing of the door. There is an incident that the mirror B slips up and the mirror B comes off the metal fitting A and the mirror B falls and is damaged.

This moves the metal fitting A downward, and the packing material 3 and the vertical piece
For particularity of mounting operations for clamping the mirror B upper end between a _3, caused by processing can not be performed to consolidate the just fastening the bracket A in accordance with threaded body 1 to a subject wall C.

In order to prevent this, for example, it can be proposed that the elongated hole for guiding the screw body is partially narrowed and the narrowed portion is used as a stopper in the lower half of the screw shaft portion of the screw body.

However, if such a means is adopted, the stopper may be scraped or bent by the pointed portion of the screw shaft whenever the lifting force acts on the mirror stopper, which may reduce the hanging force. Yes, the reliability of the mirror stop becomes poor.

The present invention has been made in view of the above conventional circumstances, and its technical problem is that when a lifting force acts on a mirror stopper, it can be converted into a clamping force to firmly hold the mirror stopper.
Further, it is an object of the present invention to provide a mirror stopper which can surely maintain the action of converting the holding force over a long period of time.

(Means for Solving the Problem) The technical means taken by the present invention to achieve the above-mentioned object is to bulge forward in a mountain shape at both edges of a middle part of a long hole for a screw guide for wall stop. The gist of the invention is to form a hooking protrusion.

(Operation) According to the above configuration, the threaded body that penetrates the elongated hole is screwed to the target wall such as the chamber wall, and the latching protrusion is positioned lower than the threaded body so that the mirror stopper is attached to the target wall. Then, the upper end of the mirror is held by the holding groove of the mirror stopper. When a lifting force is applied to the mirror stopper in this state, the front surface of the latching protrusion bites into the back surface of the lower half of the head of the screw body to firmly hold the mirror stopper between the head and the target wall. To prevent the mirror stopper from moving (raising). Also, the hooking protrusion is formed so as to bulge forward in a mountain shape, and since the bulging surface is brought into surface contact with the back surface of the lower half of the head, it is attached to the mirror stopper. There is no fear that the latching protrusion will be scraped or bent even if it comes into contact with the screw head each time the lifting force acts, and thus the movement of the mirror stopper can be reliably prevented for a long period of time.

(Effects of the Invention) As described above, according to the present invention, the latching protrusions that bulge forward in a mountain shape are formed on both edges of the middle portion of the elongated hole for guiding the screw, and the surface of the latching protrusion is formed. Since the back of the lower half of the head of the screw is hooked, the head of the screw pushes the surface of the hook every time a lifting force is applied to the mirror stopper, Firmly clamp the mirror stopper between the head and the wall.

Therefore, for example, unlike the case where the long hole is locally narrowed to form the hooking portion, the hooking edge is not scraped off by the pointed portion of the screw shaft portion, and the mirror stopper is attached. It is possible to firmly hold it and prevent it from being lifted, and it is possible to exert a stable detachment prevention function for a long period of time.

(Embodiment) Next, several embodiments of the present invention will be described with reference to the drawings.

First, the first embodiment shown in FIGS. 1 to 4 will be described. A is a mirror stopper, 1 is a screw, B is a mirror, 2 and 2 are latching projections, and 3 is a packing material.

The mirror stopper A is located on the upper end of the substrate a ₁ and has a horizontal piece a ₂ and a vertical piece a ₃
A holding groove a ₄ composed of and, and at the middle part of the long hole a ₆ opened in the central part of the substrate a _1, on the back surface of the lower half part of the head part 1 a of the screw body 1 screwed to the target mounting wall C. The latching projections 2, 2 for latching are integrally formed.

In this mirror stopper A, a ₇ is a hooking step of a packing material 3 which will be described later, and a predetermined range is stepped up from the both side surfaces of the board a ₁ across the long hole a ₆ and the board is stepped up. The cross-sections of both side portions of a ₁ and the portion parallel to the both side portions are open.

The hooking protrusions 2, 2 are formed in a mountain shape so as to have a width of about 3 mm and a height of about 1 mm at portions facing each other at the hole edge on the long side of the long hole a ₆ .

The packing material 3 has a round mouth whose diameter is approximately the entire length of the long hole a _{6 in} the center, and a portion corresponding to the hook step a ₇ is a thin portion 3 a, and further at four corners, on the back surface of the mirror B. The intimately pressed protrusion 3b is integrally formed on the front surface side.

The packing material 3 is made by mounting a mirror fasteners A by engaging the thin-walled portion 3a by utilizing the elasticity locking stepped portion a _7,圧漬projections 3b and mirror fasteners A during mounting A space slightly smaller than the mirror thickness is formed between the vertical piece a ₃ and the vertical piece a ₃ (Fig. 3).

Then, the holding groove a ₄ is positioned on the upper end of the mirror B, and the screw body 1 which penetrates the long hole a ₆ is screwed into the target mounting wall C, and the hole edge of the long hole a ₆ is screwed into the screw body 1. The head 1a and the target mounting wall C are attached to each other. At this time, the hooking protrusions 2, 2 are located above the screw body 1.

In this state, when the mirror stopper A is artificially pushed down, the hooking protrusions 2, 2 are elastically deformed by the back surface of the head 1a and do not hinder the lowering of the mirror stopper A.漬用projections 3b slightly by圧漬guided to clamping groove a _4.

On the other hand, the hooking projections 2, 2 pass through while rubbing against the back surface of the head 1a, then return to the original state and hook on the back surface of the lower half of the head 1a of the screw body 1 (FIG. 4).

Therefore, the back surface of the lower half of the head 1a of the screw body 1 and the hooking projections 2, 2
Unless the mirror stopper A is deliberately lifted with a stronger force against the hooking force with the surface, the mirror stopper A will not be lifted and the upper end of the mirror B will always be firmly attached.

In detail, when the mirror stopper A is lifted, the hook projections 2 and 2 bite into the back surface of the lower half of the head 1a, and the mirror stopper A is firmly fixed to the head 1a and the target mounting wall C. Sandwich between.
At that time, the back of the lower half of the head 1a and the hooking protrusions 2 and 2
Since the surface has a surface hooking relationship, the durability of the hooking projections 2 and 2 is also improved, and even if the hooking head 1a comes into contact each time a lifting force acts on the mirror stopper metal fitting A, the hooking projection 2 There is no fear that the second and second parts will be scraped or bent, so that the movement of the mirror stopper A can be reliably prevented for a long period of time.

Next, a second embodiment shown in FIGS. 5 and 6 will be described. This embodiment is the inner edge 2 of the hooking projections 2, 2 of the first embodiment.
a, 2a of the elongated hole a ₆ width is projected to narrow about 1 mm, its inner edge 2a, 2a is that configured to engaging in the lower half screw shaft portion 1b of Nishitai 1.

In this embodiment, the work of holding the upper end of the mirror B by the mirror stopper A is the same as that of the first embodiment, so the description thereof will be omitted. 2 and 2 are the back surface of the lower half of the head portion 1a of the screw body 1 and the screw shaft portion 1b.
Since it has a two-step disengagement prevention structure that locks on each of the lower half parts, the locking force is increased, and lifting of the mirror stopper A can be prevented more reliably, and the two-step disengagement prevention function is also lifted. Since the drag force is shared, the latching force is shared by the latching protrusion 2 and its inner edge 2a, preventing the burden on one side from increasing, and the durability of the latching protrusions 2, 2 is further improved. There is an advantage to
