Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an electrical component wall mounting device for mounting electrical components such as outlets and switches on a wall body such as a partition wall of a building body by a so-called retrofitting method.

[0002]

[Prior art]

 2. Description of the Related Art Conventionally, there is a so-called pre-installed method as a method of attaching electrical parts such as outlets and switches to a wall such as a partition wall of a building frame. This is because after fixing the box to the pillar for the wall, the wall is fixed to the pillar, an opening is opened in the portion of the wall corresponding to the box, and the box is passed through the opening. In this construction method, first, the box is fixed, then the work is temporarily interrupted and the wall body is fixed, and then the electrical equipment is fixed with screws. It is necessary to restart the work and fix the electric parts to the box with screws, and it takes time to attach the electric parts, resulting in a low work efficiency.

A so-called post-mounting method has been developed as a solution to the drawbacks of the pre-mounting method, and an example thereof is a technique described in Japanese Utility Model Publication No. 50-137594. This is because the wall is fixed to the building frame, the opening is opened in the wall, the box is fitted into the opening, and the fixed stopper piece provided in the front part of the box is attached to the wall. By contacting the surface, and then rotating the stopper bolts rotatably provided on the upper and lower parts of the box, the movable stopper pieces arranged on the upper and lower parts of the box are erected to raise the back surface of the wall. And the movable stopper pieces are moved so as to be pressed against the back surface of the wall body, thereby fixing the box to the wall body. Subsequently, electrical parts such as outlets and switches are fixed to the box with fixing bolts.

[0004]

[Problems to be solved by the device]

 In the above-mentioned conventional post-installation method, a stopper bolt and a movable stopper piece are used to fix the box to the wall body, and fixing bolts are used to fix the electric parts to the box. In addition, the manufacturing cost is high, and the work of fixing the box and the work of fixing the electric parts need to be performed separately, which is troublesome and troublesome.

In view of the above-mentioned conventional problems, the present invention has a small number of parts and a low manufacturing cost, and furthermore, an electric part wall mounting device capable of quickly and easily attaching electric parts to a wall body. Is intended to provide.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the invention according to claim 1 is such that a support frame is fitted into an opening formed in a wall body such as a partition wall of a building frame, and the support frame is provided with an electrical component such as an outlet or a switch. A wall mounting device for electrical parts, wherein the support frame is fitted into the opening and a screw hole for bolting an electrical part is formed at a predetermined position, and a frame main body of the frame main body. A front stopper piece that is integrally formed on the front portion and abuts on the surface of the wall body; and a rear stopper piece that integrally projects from the rear portion of the frame body adjacent to the screw hole. The rear stopper piece is pressed by a bolt that is screwed into the screw hole, and is bent around a thin hinge portion formed at the root of the rear stopper piece so that the tip end of the stopper piece comes into contact with the back surface of the wall body. It is characterized by That.

The invention according to claim 2 is characterized in that the support frame is provided integrally with a rear portion of the frame main body and has an auxiliary stopper piece elastically pressed against the peripheral edge of the opening. .

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. 1 to 3, a support frame 3 is fitted into an opening 2 formed in a wall body 1 such as a partition wall of a building body, and an electrical component 4 such as an outlet or a switch is fixed to the support frame 3 with a bolt 5. It shows the wearing state.

As shown in FIG. 4, the support frame 3 is an integrally molded product made of synthetic resin and is fitted into the opening 2, and screw holes 6 for bolting electric parts are formed in the upper and lower parts. A rectangular frame main body 7, a front side stopper piece 8 which is integrally formed on a front side surface of the frame main body 7 and comes into contact with the front surface of the wall body 1, and the screw hole 6 at the rear portion of the frame main body 7. And a pair of rear stopper pieces 9 integrally projecting at a position adjacent to the rear stopper pieces 9. Each of the rear stopper pieces 9 has a substantially T shape and extends horizontally from the frame body 7 toward the rear. At the same time, a stopper piece body 9a having a thin hinge portion 11 formed at its root portion and a stopper portion main body 9a branched at a right angle from the central portion of the stopper piece body 9a to face the screw hole 6 and have a thin wall portion at the root portion. And a branch portion 9b in which the hinge portion 12 is formed, The branch portion 9b is pressed by the bolt 5, the stopper piece main body 9a is bent around the thin-walled hinge portion 11, and the tip end portion 9c thereof is brought into contact with the back surface of the wall body 1, thereby supporting The frame 3 is fixed to the wall body 1.

As shown in FIG. 4, a pair of auxiliary stopper pieces 15 are integrally projecting rearwardly on both side surfaces of the rear portion of the frame body 7 so as to extend outward, and both auxiliary stopper pieces 15 are pressed. After the frame main body 7 is fitted into the opening 2 while being elastically displaced inside the frame main body 7, the both auxiliary stopper pieces 15 are combined by releasing the pressing of the both auxiliary stopper pieces 15. The elastic force peculiar to the resin can be pressed against the peripheral portion of the opening 2, whereby the support frame 3 can be easily temporarily fixed to the opening 2. The anti-slip concave-convex portion 16 is formed on the surface of the auxiliary stopper piece 15 facing the opening.

In FIG. 1, reference numeral 17 denotes an exterior frame, which is attached to the electrical component 4 by screwing a screw 19 into a screw hole 18 formed in the support substrate 4 a of the electrical component 4 through the exterior frame 17. To be Reference numeral 20 is a through hole for the bolt 5 which is provided through the support substrate 4a.

In the above configuration, when the electric component 4 is attached to the wall body 1, after opening the opening 2 in the wall body 1 fixed to the building body, both auxiliary stopper pieces 15 are pressed to press the frame body. The frame main body 7 is fitted into the opening 2 in a state of being elastically displaced inside 7, and the front stopper piece 8 is brought into contact with the surface of the wall body 1 to release the pressing of the both auxiliary stopper pieces 15. As a result, both auxiliary stopper pieces 15 are elastically pressed against the peripheral edge of the opening 2, and the support frame 3 can be temporarily fixed to the opening 2. Next, as shown in FIG. 5A, the electric component 4 is fitted in the frame body 7, and the bolt 5 is screwed into the screw hole 6 through the through hole 20 of the supporting substrate 4a of the electric component 4. As a result, as shown in FIG. 5B, the tip of the bolt 5 presses the branch portion 9b of the rear stopper piece 9, whereby the stopper piece body 9a is bent outward with the thin hinge portion 11 as the center. Then, the tip portion 9c is brought into contact with the back surface of the wall body 1. Then, as the bolt 5 is further screwed in, the branch portion 9b is slightly bent around the thin hinge portion 12 as shown in FIG. It is possible to securely hold the engagement state of the piece 9 with the wall body 1 and to securely fix the support frame 3 to the wall body 1 and prevent loosening of the bolt 5; Thus, the electric component 4 can be securely fixed to the wall body 1.

[0015]

[Effect of device]
