Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a synthetic resin mounting frame for mounting appliances such as switches, outlets, and indicator lamps.

A conventional mounting frame made of metal as shown in FIG. 1 is widely used.

That is, the mounting opening of the mounting frame A is provided with a hole C for a fixing screw that is screwed into a wall, an embedded box, etc., and a device E having horizontal holes 2 at both ends is fitted between the holes C and C. Further, the left and right connecting portions connecting the mounting portion openings are provided with a protrusion that engages with the horizontal hole 2, and one of the connecting portions is provided with a slot. A thin-walled portion with a protrusion is formed between the instrument hole and a screwdriver Y is inserted into the slot and pried to deform the thin-walled portion to protrude and engage the horizontal hole 2 of the instrument body. This is to fix the instrument E to the mounting frame A.

Therefore, during fixing work, it is necessary to bend the thin-walled part with a screwdriver Y, resulting in poor work efficiency.In addition, if the tool H breaks down for some reason, the first thing to do when replacing the tool is to use a screwdriver X to pry the thin-walled part. It is necessary to restore the deformation of the part to its original state, remove the instrument E, and then bend the thin part with a screwdriver Y to fix the new instrument E again.

Therefore, thin-walled parts may break due to repeated bending.

In addition, since the thin-walled portion A protrudes and deforms without providing a guide and engages the horizontal hole 2 of the instrument E, when multiple instruments E are fixed to one mounting frame A, the thin-walled It is a difficult task to bend the part evenly with the driver Y.

Therefore, due to the vertical ups and downs of this thin-walled part, the equipment is not aligned vertically, resulting in poor workmanship.

This invention was made focusing on the above circumstances,
The purpose of this product is to eliminate the need for bending with a screwdriver as it is made of elastic synthetic resin, to allow the instrument to be fixed with a single touch without the use of tools, and to allow repeatable instrument replacement. To provide a mounting frame which facilitates the removal of instruments and does not cause misalignment even when a plurality of instruments are fixed.

An embodiment of the present invention will be described below with reference to FIGS. 2 to 6 in which it is used in an electrical outlet.

Reference numeral 1 denotes an instrument, in which a container body 2 and a lid body 3 are assembled together using a fastening fitting 4.

A pair of protrusions 5 are provided on the fastening metal fittings 4 provided on both sides of the instrument 1.

Incidentally, this protrusion 5 may be provided directly on the container body 2 or the lid body 3.

Reference numeral 6 denotes a mounting part, in which fixing screws (not shown) are screwed into a wall, an embedded box, etc. at both ends of a frame 8 in which a window hole 7 is formed that is large enough to fix three instruments 1 in parallel. ) forms a hole 9 through which it passes.

By forming the stepped portions 10 at both ends of the mounting portion 6, it is possible to prevent the mounting frames X from shifting from each other when the mounting frames X are arranged in series.

Reference numerals 11a and 11b are connection parts, which connect the mounting parts 6 to each other, and one of the connection parts 11a has a rectangular hole 12 that engages the protrusion 5 provided on the instrument 1, and the other connection part 11b has a An elastic piece 1 is provided with a hanging piece 13 having an angular cross-section, and a U-shaped groove 14 is formed in the hanging piece 13 so that both side parts and the upper part are separated and bent, and a surface 15 is inclined inwardly and upwardly.
6 and corresponding to the elastic piece 16
A protrusion 17 protruding into the groove 14 is provided at position b.

18 is a recess formed inside the elastic piece 16.

A rib 19 is formed on the upper part of the elastic piece 16 and faces the protrusion 17, and serves as a guide when inserting the driver Y into the groove 14.

In order to fix the instrument 1 to the mounting frame X, first, the protrusion 5 of the instrument 1 is engaged with the hole 12 formed in the connecting portion 11a.

Thereafter, the instrument 1 is rotated using this engaging portion as a fulcrum.

Then, the protrusion 5 comes into contact with the surface 15 that is inclined inwardly and upwardly, and the elastic piece 16 bends due to the elasticity of the synthetic resin.When the protrusion 5 comes to a position corresponding to the upper part of the elastic piece 16, the protrusion 5 comes into contact with the lower surface of the connecting portion 11b, and the elastic piece 16
The instrument 1 is fixed to the mounting frame X by placing it on the upper part of the frame and locking it.

A hole 20 formed in the mounting portion 6 is for screwing a fixing screw (not shown) into the wall surface when the hole 9 is not available.

A pointed protrusion 21 provided on the back surface of the mounting portion 6 bites into the wall surface and prevents the mounting frame X from slipping.

The hole 22 is for attaching a plate (not shown) to the front surface of the mounting frame X.

The protrusion 23 is for collecting looseness between the mounting frame X and the instrument 1.

The L-shaped hole 24 is for locking an L-shaped fitting (not shown) for fixing the mounting frame X to a wall surface.

Further, to remove the instrument 1 from the mounting frame X, as shown in FIGS. 6a and 6b, a screwdriver Y is inserted into the groove 14 between the instrument body 1 and the elastic piece 16 using the rib 19 as a guide.

At that time, the driver Y is inserted into the recess 18 formed in the elastic piece 16.
This prevents the screwdriver Y from shifting when the protrusion 17 is used as a fulcrum to pry the screwdriver Y.

Note that the recess 18 may be provided in the instrument 1. Then, the device 1 is removed by bending the elastic piece 16 and removing the protrusion 5 that is locked to the upper part.

In addition, since the elastic piece 16 locks the protrusion 5, that is, returns to the original state formed by plastic molding and fixes the instrument 1, when a plurality of instruments 1 are fixed to one mounting frame Also, each elastic piece 16 locks the protrusion 5 uniformly.

As explained above, in this invention, one connecting part 11a is formed with a hole 12 for engaging the protrusion 5, and the other connecting part 11b is formed with a hole 12 for engaging the protrusion 5.
The hanging piece 13 is provided with a cross-section having an L-shaped cross section, and the hanging piece 13 has an elastic piece 16 which is bent by separating both side parts and an upper part and has a surface 15 that is inclined inwardly and upwardly.
Due to the elasticity of the screwdriver Y, the bending work by the screwdriver Y is eliminated, and the instrument 1 can be fixed in one touch by simply rotating the hole 12 as a fulcrum without using any tools, and the instrument 1 can be replaced easily. Furthermore, the tool 1 can be easily removed by simply inserting a screwdriver Y into the groove 14 between the instrument 1 and the elastic piece 16 and prying to deflect the elastic piece 16. Since the protrusion 17 is provided on the connecting portion 11b, the driver Y
When the elastic piece 16 is strained, the deflection of the elastic piece 16 increases, making it easier to remove the instrument 1.

Further, since each elastic piece 16 locks the protrusion 5, that is, returns to the original state formed by plastic molding and fixes the instrument 1, each elastic piece 16 locks the protrusion 5 uniformly. ,
The elastic piece 16 does not rise or fall.

Therefore, even if multiple instruments 1 are fixed to one mounting frame
A mounting frame that prevents the fixture 1 from being vertically uneven and has an electrically insulating effect can be obtained.
