Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a structure in which a storage box is installed by being embedded in the wall of a room.

[Prior art]

Conventionally, when installing the storage box 1 by embedding it in the wall W, the storage box 2 is placed between the vertical members 1 to be installed, which are erected to face each other with a gap between them, as shown in FIGS. 6 and 7. Install the storage box 2 by screwing the mounting screws 3' into the vertical member 1 to be installed from the inner surface of the side plate 8 of the storage box 2, and then attach the external threaded part 6' of the shelf support dowel 9' to the side plate 8. A vertical support dowel 9' was attached by screwing into the side plate 8 from the inside surface.

[Problem that the invention attempts to solve]

In the conventional example described above, the mounting screws 3' are simply screwed into the inner surface of the side plate 8 for installation, so there is a problem that the heads of the mounting screws 3' are exposed on the inner surface of the side plate 8, resulting in poor appearance. be. Also, the shelf support dowel 9' is attached by screwing the male threaded part 6' into the side plate 8, so in order to install the shelf support dowel 9', it is necessary to screw it into the side plate 8 like a wood screw. There was a problem that the mounting structure was complicated, and since it was simply screwed into the side plate 8, the mounting strength was weak.

[Means to solve the problem]

In order to solve the problem of the head of the mounting screw 3' being exposed, the mounting screw 3 with the screwdriver bit insertion groove 7 formed in the head 4 is inserted into the through hole 12 of the side plate 8 of the storage box 2 from the inner surface of the side plate 8. The problem is that the head 4 is inserted and screwed into the vertical member 1 to be attached, and the head 4 is positioned in the through hole 12, and the installation of the shelf support dowel 9' is complicated, and the installation of the shelf support dowel 9' is complicated. In order to solve the problem of weak strength, the male threaded part 6 formed on the shelf support dowel 9 is screwed into the female threaded hole 5 of the mounting screw 3, and the shelf support dowel 9 is made to protrude from the inner surface of the side plate 8. Ta.

〔Example〕

Reference numeral 2 in the figure is a wall-embedded storage box, which is installed between vertical members 1 to be installed such as wall studs. 10 is placed on it. Reference numeral A denotes a storage box mounting bracket, which is composed of mounting screws 3 and shelf support dowels 9. The threaded portion 11 of the mounting screw 3 is formed into a conical shape, and the maximum diameter of the threaded portion 11 is approximately the same as the outer diameter of the cylindrical head 4 of the mounting screw 3. A female threaded hole 5 is formed in the head 4 of the mounting screw 3 in the axial direction, and a driver bit insertion groove 7 is cut out in the peripheral wall of the female threaded hole 5. The shelf support dowel 9 is formed in a cylindrical shape with approximately the same diameter as the head 4 of the mounting screw 3, and a male threaded portion 6 is integrally formed with the shelf support dowel 9 on the axis of the shelf support dowel 9. ing. In order to embed and fix the storage box 2 to the wall W using the storage box mounting bracket A configured as described above, first place the storage box 2 between the vertical members 1 to be installed, and then insert the side plate 8 from the inner surface of the side plate 8. Insert the mounting screw 3 into the through hole 12, insert the screwdriver into the screwdriver bit insertion groove 7, and insert the mounting screw 3 from the side plate 8 into the vertical member 1 to be mounted.
At the same time, the head 4 of the mounting screw 3 is positioned in the through hole 12 of the side plate 8. Finally, the male threaded part 6 of the shelf support dowel 9 is screwed into the female threaded hole 5 of the head 4 of the mounting screw 3 while rotating by hand, so that the shelf support dowel 9 is projected inward of the storage box 2.

FIG. 5 shows another embodiment of the present invention, in which a stepped through hole 12 is provided in the side plate 8 of the storage box 2, and the mounting screw 3 is screwed into the vertical member 1 to be installed through this through hole 12. The structure is such that the head 4 is positioned in the deep hole of the through hole 12, and a part of the shelf support dowel 9 with the male screw part 6 screwed into the female screw hole 5 is inserted into the through hole 12. be.

[Effect of idea]

In this invention, a mounting screw with a screwdriver bit insertion groove in the head is inserted into a through hole in the side plate of the storage box from the inside surface of the side plate, screwed into the vertical member to be installed, and the head is positioned in the through hole. As a result, the head of the mounting screw is not exposed on the inner surface of the side plate, improving the appearance. Since the shelf support dowel is made to protrude from the inner surface of the side plate, it goes without saying that the head of the above-mentioned mounting screw becomes even more invisible when the shelf support dowel is installed.
The installation work of the shelf support dowel only requires screwing into the pre-formed female thread part, which improves the efficiency of the installation work.Moreover, the shelf support dowel is integrated with the mounting screw, so the shelf support dowel The installation condition becomes stronger,
Furthermore, there is an advantage that the shelf support dowel is not damaged during the installation work of the shelf support dowel.
