Description

[Detailed description of the invention] The present invention relates to a mounting device for wiring devices, and its purpose is to install wiring devices that allow easy attachment and removal of wiring devices without applying excessive force to the mounting frame or wiring devices. We are here to provide you with the equipment.

Conventionally, in order to embed wiring devices such as switches and outlets into the wall, a mounting frame was attached to a wiring box in a recessed part of the wall, and when installing the wiring device to the mounting frame, the sixth
Using the mounting frame 4' as shown in the figure, fit the wiring device 1' into the fitting hole 5' of this mounting frame 4', and insert the wiring device 1' into the locking claw 6' on one side of the fitting hole 5'. Lock one side, insert the screwdriver into the driver groove 9, and swage the locking claw 6'' on the other side of the fitting hole 5' and the locking recess 10 on the other side of the wiring device 1' to fix it. However, in this case, the fixing strength varies depending on the skill level of the worker, for example, if the device is assembled backwards (upside down) or if the wires are connected incorrectly, it may be necessary to use a screwdriver to remove the device. This is not easy and requires a considerable amount of work, requiring labor savings.

In addition, when attaching and detaching, it is necessary to secure the mounting frame and the device with one hand and operate the screwdriver with one hand, resulting in poor workability.

The present invention solves these conventional drawbacks.

The present invention will be explained in detail below based on the illustrated embodiments.

The wiring device 1 is installed by being embedded in a fixed position such as a wall or floor, such as a switch or an outlet, and the mounting frame 4 is installed by being embedded in a wall or floor in order to fix the wiring device 1 in a fixed position. It is installed in a built-in wiring box.

At one end of the wiring device 1, as shown in FIG.
1 is attached by means of attachment means such as screws, rivets, caulking, etc., and a substantially U-shaped second frame 12 is similarly attached to the other end.

Protruding pieces 13 are provided on the upper surface of the first frame 11, and these protruding pieces 1
A through hole is provided in 3.13 to form the locking portions 2, 2.

On both sides of the second frame 12, hooks having claw portions 8, 8 at the upper end are extended upward from the claw pieces 3, 3'.

The claw piece 3 of this hook has elasticity, and the upper surface of the hook/nail part 8 is on a slope 14.

The mounting frame 4 is provided with a fitting hole 5, and one end edge of the fitting hole 5 has a locking pawl 6 corresponding to the locking portions 2, 2.
．． 6 are provided, and projecting pieces 20 and 20 are provided in a slightly forward position of both ends of the other end edge 7 by cutting and raising to constitute a support portion Y.

When installing the wiring device 1 to the mounting frame 4, please refer to Figure 3a.
Place the wiring device 1 on the underside of the mounting frame 4 as shown in the figure, hold it diagonally, hook the locking parts 2, 2 onto the locking claws 6, 6, and then push up the wiring device 1 as shown by the arrow to remove the third As shown in the figure, the hooks of the claw pieces 3, 3 hook the claw portions 8, 8 onto the other end edge 7 of the fitting hole 5.

During this push-up operation, each hook is attached to the slope 14 of the claw portion 8.
slides on the other edge 7 of the fitting hole 5, and each hook is connected to the claw piece 3.
is press-fitted and passed through the fitting hole 5 against the spring elasticity.

When removing the wiring device 1, as shown in FIG.
, push down the jig X in the direction of the arrow using the protruding piece 20 as a fulcrum, displace the claw piece 3 backwards, detach the claw part 8 from the other edge 7, and remove the wiring device. 1 can be removed from the mounting frame 4.

FIG. 4 shows a mounting frame 4 according to another embodiment of the present invention, in which protruding pieces 20', 20' are provided protrudingly at positions along both side edges of the fitting hole 5, and the supporting portion Y It consists of

When removing the wiring device 1 from the mounting frame 4, one leg 21a of a jig The wiring device 1 is removed from the mounting frame 4 by being engaged with the portion 8 and pinched from both sides, the hook displacing the claw piece 3, and the hook disengaging the claw portion 8 from the other end edge 7 of the fitting hole 5. Can be done.

In the above embodiment, the first frame 11. When the second frame 12 is attached to the wiring device 1, it is fixed using a driving stud.
Of course, other means such as caulking may also be used.

As mentioned above, the present invention provides a locking part at one end of the wiring device, and a spring-elastic hook is provided on both sides of the other end, and the fitting hole of the mounting frame is locked at one edge of the hook. Since a claw is provided, when installing the wiring device, all you have to do is to lock the locking part into the locking claw, and then forcefully push up the wiring device. It is deflected by the wire and passes through the fitting hole, and after passing through, it is restored by its own spring elasticity and the hook is caught on the other edge of the fitting hole, making it difficult to install the wiring device. On the other hand, when removing the wiring device, the fulcrum of the jig is supported by the protruding piece, so there is no need to apply excessive force to the mounting frame itself. Since it can be displaced using a jig, the wiring device can be easily removed even if the removal work is performed while holding the mounting frame with one hand, and as mentioned above, the direct hook allows the claw to be easily displaced. Since the hook can strengthen the spring elastic force of the claw piece, the wiring device can be fixed without wobbling, and as mentioned above, the hook uses the spring elasticity of the claw piece to attach the wiring device. Therefore, there is no difference in fixing strength due to different installers as in the past, and anyone can install with the same strength.

In particular, since the hook protrudes from the front end in the width direction of the hook piece, the hook can be hooked by the hook part in a direction where the hook piece is less likely to bend, so it can be securely fixed. Wiring devices cannot be easily removed by external force.
