Description

[Detailed description of the invention] The present invention relates to a mounting frame for attaching appliances such as outlets and switches, and more specifically, a mounting opening 2 is provided approximately in the center of the mounting frame 1, and a fixing protrusion is provided on one side of the mounting opening 2. 3 protruding,
One end of a lever 4 is rotatably pivoted near the other side of the mounting opening 2, and a cross groove 6 into which the tip of a Phillips screwdriver 5 can be inserted is provided on the upper surface of the pivoting side end of the lever 4. This relates to a mounting frame in which a movable protrusion 7 is formed on the other side of the mounting opening 2, and the movable protrusion 7 projects into the mounting opening 2 by a lever force when turned.

In the case of a conventional mounting frame, as shown in FIG. I could only use a flat head screwdriver 9.

Therefore, use Phillips groove screws for fixing the mounting frame.
Even if the construction is simplified, a flathead screwdriver must be used when installing the device, and it is time consuming to replace the screwdriver.

The present invention was developed in view of the above-mentioned drawbacks, and its purpose is to allow the movable protrusion to protrude using a Phillips screwdriver, and to allow the entire process from attaching the mounting frame to attaching the device to the mounting frame. To provide a mounting frame that can be worked with a Phillips screwdriver and has good workability.

The present invention will be explained in detail below with reference to the accompanying drawings.

What is shown in FIG. 2 is the first embodiment, in which a mounting opening 2 is provided approximately at the center of the mounting frame 1, a fixing protrusion 3 is provided on one side of the mounting opening 2, and Mounting opening 2 on the side
A movable protrusion 7 that can protrude inward is provided opposite the fixed protrusion 3, and a through hole 11 is bored in the center of the movable protrusion 7.

Further, upper bent portions 12 are provided upright on both sides of the outer periphery of the mounting frame 1.

Reference numeral 4 denotes a lever bent in a substantially oval shape, with a leg 13 hanging downward from the lower surface of one end of the lever 4, and a cross groove 6 bored in the upper surface of the lever 4 directly above the leg 13; At the same time, the minus groove 14 is also formed in combination with the cross groove 6.

This lever 4 has its leg 13 inserted into the through hole 11 of the movable protrusion 7, and after insertion, the lower end of the leg 13 is crushed and squeezed so that the lever 4 can rotate to the movable protrusion 7 of the mounting frame 1 and will not come off. It is pivoted to.

An active end 15 of the lever 4 opposite to the pivot side comes into contact with the inner surface of the upper bent portion 12 by rotating the lever 4.

Reference numeral 10 indicates a device such as an outlet or a switch, and a fitting recess 16 and a step portion 17 below the fitting recess 16 are provided on both sides thereof.

To attach the instrument 10 to the mounting frame 1, proceed as follows.

Insert the upper part of the instrument 10 into the mounting opening 2, fit one fitting recess 16 of the instrument 10 into the fixing protrusion 3 of the mounting frame 1, and bring the stepped part 17 of the instrument 10 into contact with the lower surface of the mounting frame 1. .

Next, when the tip of the Phillips screwdriver 5 is inserted into the cross groove 6 and the Phillips screwdriver 5 is turned in the A direction, the working end 15 of the lever 4 comes into contact with the upper bent portion 12 as shown in FIG. 5, the working end 15 strongly presses the upper bent part 12, and the reaction force causes the movable protrusion 7 to protrude into the mounting opening 2, as shown in FIG. The instrument 10 is fixed to the mounting frame 1 by being fitted into the matching recess 16.

Of course, there is a cross groove 6 and a minus groove 1 at the end of the lever 4.
4 is also provided, so it goes without saying that the instrument 10 can also be attached using a flathead screwdriver 9.

Conversely, to remove the instrument 10 from the mounting frame 1, insert the tip of the flathead screwdriver 9 into the driver insertion hole 18 provided on the side of the movable protrusion 7, and twist the flathead screwdriver 9f to remove the side protrusion of the movable protrusion 7. Each time the piece 19 is moved backward, the movable protrusion 7
The device 10 can be removed by retracting it.

Moreover, what is shown in FIG. 7 is a second embodiment of the present invention.

In other words, a leg 13 is suspended from the lower surface of one end of the straight lever 4, and a cross groove 6 and a minus groove 14 are formed in combination on the upper surface of the end of the lever 4 directly above the leg 13, and the other end of the lever 4 is further provided with a cross groove 6 and a minus groove 14. The working legs 20 are suspended.

The legs 13 of this lever 4 were inserted into the shaft circumferential holes 21 provided near the movable projection 7 of the mounting frame 1 as shown in FIG. 7, and the working legs 20 were inserted into the through holes 11 of the movable projection 7. back, leg 1
The lower end of the leg 3 is crushed and tightened, and the leg 13 is pivotally attached to the mounting frame 1 so that it can rotate and not come off.

Therefore, in order to attach the device 10 to the mounting frame 1, the method shown in FIG.
, l), insert the tip of the Phillips screwdriver 5 into the cross groove 6.
, turn the Phillips screwdriver 5 to rotate the lever 4 toward the mouth to project the movable protrusion 7 into the mounting opening 2, and fit the movable protrusion 7 into the fitting recess 16 of the instrument 10. Equipment 1
It is fixed at 0.

Conversely, in order to remove the instrument 10, it is better to turn the Phillips screwdriver 5 inserted into the cross groove 6 in the direction opposite to the direction of the mouth.

The above mounting frame is used as a recessed outlet or a recessed switch, and the mounting frame is attached to the recessed box so that the recessed box, such as an outlet or a switch, fits into the recessed box embedded in the wall, and the front side of the mounting frame is A decorative cover can be attached to the.

As described above, in this invention, the movable protrusion can be made to protrude into the mounting opening by turning a Phillips screwdriver whose tip is inserted into the cross groove, so the device can be attached to the mounting frame using the Phillips screwdriver. Therefore, the three steps of attaching the equipment to the mounting frame, screwing the mounting frame to the embedded box, and screwing the decorative cover to the mounting frame can all be done with a single Phillips screwdriver, resulting in excellent workability. There are advantages.
