Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the art of mounting appliances such as switches and outlets on m-planes.

When installing appliances such as switches and outlets on walls, frames are generally used to mount them.

The frame is generally made of a metal plate to form a rectangular main body, and an instrument insertion hole is formed in this main body, and engaging protrusions are provided protruding from both sides of the instrument insertion hole, facing each other. A substantially T-shaped caulking operation part is provided on the outside of the engagement protrusion, and a caulking operation hole is further formed around the T-shaped caulking operation part.

In the mounting formed in this way, the frame fits the instrument between the opposing engagement protrusions in the instrument insertion hole, engages the engagement protrusion on one side with the retaining part on one side of the instrument, and engages the engagement protrusion on one side with the engagement protrusion on the other side. Install the instrument by inserting an operating tool such as a screwdriver into the caulking operation hole on the side, pressing the caulking operation part, and engaging the retaining protrusion on the other side with the other engaging part of the appliance. I try to fix it neatly.

Therefore, when installing the device, the device must be caulked using an operating tool such as a screwdriver, which is inconvenient as the installation process is troublesome.

Therefore, for example, as described in Japanese Utility Model Publication No. 56-9297, the frame is made of synthetic resin, and the engaging protrusion is elastically engaged with the retaining part of the instrument. has been proposed to make the work easier.

Installation must be done by inserting a screwdriver from the back side of the frame into the gap provided, and when replacing equipment, the frame must be removed from the wall, which not only makes the work troublesome, but also The container is also installed on the frame! There are disadvantages such as the need for a special device that can form a gap with the l wall.

On the other hand, as described in Japanese Patent Application Laid-open No. 55-103015, a synthetic resin mounting with elastic protrusions has been proposed in which a screwdriver can be inserted from the front side of the piece to remove the instrument. has been done.

However, with this method, a screwdriver is inserted between the side of the device and the wall surface of the mounting piece, and the device is removed by pressing the elastic protrusion, which not only makes the work of inserting the screwdriver troublesome. There are disadvantages such as the operating angle of the driver is small, making it difficult to drive out of range.

The present invention has been made in consideration of the above-mentioned circumstances, and it is an object of the present invention to provide an instrument mounting frame that has a simple structure and allows for easy attachment and removal of instruments.

The present invention is equipped with an engaging protrusion, at least one of which is provided opposite the instrument insertion hole in the frame main body, and which elastically engages a retaining portion of the instrument; The device is characterized in that it is made of synthetic resin and includes a wall surface portion that comes into contact with the wall surface portion and an operation tool insertion portion that is cut out and opened on the front side of the wall surface portion.

The details of the invention will be explained below with reference to the illustrated embodiments. 1 is mounted on a frame, and the frame 1 is plate-like mounted on the frame body 2, and this mounting is performed on an instrument insertion hole 3 provided in the frame body 2 and opposite sides of this instrument insertion hole 3. The mating device ^ installation has part 4.5. In this embodiment, the frame body 2 is made of synthetic resin and formed into a rectangular plate shape.
A mounting piece 6.6 is provided at both ends;
A rectangular instrument insertion hole 3 is formed between ゜6, and
A pair of instrument mounting portions 4.5 located opposite to each other on both sides of the instrument insertion hole 3 are formed integrally with the frame body 2 from synthetic resin. One of the parts 4 is formed of a retaining piece 7 that protrudes into the instrument insertion hole 311, and the other part 5 protrudes toward the instrument insertion hole 3 and is elastically attached to the retaining part 4 of the instrument insertion hole 3, which will be described later. It is formed to include a retaining piece 8 that engages with a retaining piece 8, a wall surface portion 9 that comes into contact with the side surface of the instrument addition, and an operating tool insertion portion W that is cut out and opened in the front surface of the wall surface portion 9. There is.

To be more specific, the other instrument mounting section 5 is provided with a rising piece 11 formed in a square block shape, facing the retaining piece 7 of the one instrument mounting section 4, and behind this rising piece 11. A retaining piece 8 protrudes from the edge, a wall portion of the rising piece 11 is a wall portion 9, and a portion of the wall portion 9 is cut out to form an operating tool insertion portion 10.

12 is a mounting hole provided in the piece 6.6, and 13 is a plate mounting hole.

Furthermore, this attachment allows for additional appliances to be attached to the frame 1, such as switches, electrical outlets, and other wiring appliances. In this embodiment, this device attachment is a switch, and for example, as shown in FIG. The cover part is fixed with a connecting fitting 5, and frame-shaped retaining parts 21 integrally formed with the connecting fitting 5 are arranged on both sides of the cover part.

Next, the effect will be explained. To attach the instrument adder to the frame 1, insert the instrument adder into the instrument insertion hole 3, attach the stepped portion U to the back of the frame body 2, and attach one retaining portion 21 to the other retainer piece. Since the retaining piece 8 is formed to be elastically secured to the frame 1
It can be attached to the frame 1 without using any tools by simply pressing it.

Next, in order to install and remove the equipment from frame 1, please refer to Figure 3 1.
As shown, by inserting and prying the operating tool I such as a screwdriver into the operating tool insertion portion 10, the retaining piece 8 is inserted and the instrument is removed. At this time, the instrument is attached to the operating tool insertion section 1 of section 5.
Since 0 is formed with a notch, it is possible to easily insert the operating tool (materials), and the operating angle of the operating tool I can be increased by lever action using the front corner A of the instrument as a fulcrum.
Easy to add and remove equipment.

Although the invention has been described in detail with respect to the above embodiments, the invention is susceptible to various embodiments. For example, for installation, the frame body is formed of a metal plate, an engagement piece is formed integrally with the frame body on one side of the instrument insertion hole, and an engagement piece is formed on the other side of the instrument insertion hole. The mounting plate made of synthetic resin forming the piece, wall surface portion, and operating tool insertion portion may be formed by attaching a portion. Alternatively, the engaging piece, the wall surface portion, and the operating tool insertion portion may be provided oppositely to each other on both sides of the instrument insertion hole.

As described in detail above, the present invention includes a retaining piece in which at least one of the instrument mounting parts provided opposite to the instrument insertion hole of the frame main body elastically engages with the engagement part of the instrument; The device is made of synthetic resin, including the wall surface that abuts the side surface of the device and the operating device insertion portion that is cut out and opened on the front side of this wall surface, so that the device can be held in place by absorbing the elastic force of the engaging protrusion. It can be easily attached to the frame without using any tools, and when removing the device, insert an operating tool such as a screwdriver into the operating tool insertion part and use the front corner of the instrument as a fulcrum. It can be easily removed by levering the retaining piece. Moreover, when removing the instrument, the operating tool insertion portion serves as a guide for the operating tool, making it easier to remove the instrument.
