Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a device for mounting appliances such as floor sockets.

Conventional techniques and problems to be solved by the invention Conventionally, for example, in the case of a floor outlet (floor-embedded outlet), the floor plate was fixed to the outlet box under the floor. Publication No. 1987-45789, Publication No. 173229-1983
There are mounting methods as shown in publications, etc. In other words, there are two methods: one is to use scissors and a nut, and the other is to directly attach it to a screw hole formed in the box coating cover of the outlet box. However, in the case of the conventional type, the scissor metal fitting type can only be attached using the scissor metal fittings. This is because the mounting screws are sized to fit inside through the round holes of the outlet box in the returned state, so the spacing between the mounting screws is smaller than the spacing between the round holes in the box. For this reason, the box cover has a convex part that protrudes toward the round hole side to form a screw hole for direct installation, and when using scissor metal fittings, this convex part can be cut or bent. This is what we do.

Therefore, the present invention has a mounting method using scissor metal fittings,
The purpose of the attachment of the instrument is to obtain a device in which different attachment methods such as a direct attachment method can be easily selected and the attachment can be carried out.

SUMMARY OF THE INVENTION The present invention provides a hole 27 in a device body, for example a floor plate 1 for a floor outlet, which is sized to encompass a plurality of fixing positions.
A plurality of bushings 28 are provided in the holes 27 and fitted into the bushings 28 at certain positions.
The mounting employs a configuration in which a mounting screw 20 is positioned at a fixed position, for example, a nut 26 or a screw hole 24, depending on the position.

The hole 27 formed in the working floor plate 1 has a size that includes a plurality of fixing positions, and the bushing 28 that fits into this hole 27 has an eccentric insertion hole 31 for the mounting screw 20 formed therein. By simply changing the fitting direction of the bushing 28 into the hole 27 and changing the position of the insertion hole 31, you can easily select whether to install the mounting screw 20 to the nut 26 or to the screw hole 24. It becomes possible to set.

Example An embodiment of the present invention will be described based on the drawings.

This embodiment is applied to a floor outlet.

Therefore, first we will provide an overview of floor outlets. First, a floor plate 1 placed on the floor has a circular opening 2 in the center, and a cover 4 with an integrally built-in outlet 3 is provided at the bottom of this opening 2. . This integral cover 4 is rotatable about a shaft 5, similar to that shown in the above-mentioned publication, and is biased upward by a torsion spring or the like (not shown), as shown by the dashed line in FIG. The outlet 3 is configured to be exposed to the outside through the opening 2. and,
A recess 6 is formed in a part of the floor plate 1, and a lever 7 is provided in the recess 6 so as to be freely movable in the radial direction. This lever 7 is attached to the cover 4 at the tip on the side of the opening 2.
A pawl 9 that engages and disengages from the locking portion 8 is attached by a screw 11 via a spacer 10, and an elongated hole 12 is formed in the floor plate 1 to guide the advancement and retreat of the pawl 9.

An operating cylindrical body 13 is arranged on such a lever 7 so as to be freely rotatable through a hole 14, slightly shifted to one side. A slit 16 is formed at the top of the operating cylindrical body 13, which can be rotated by a coin 15, for example. Further, a lock piece 1 is provided on the lower side of the operating cylindrical body 13 and protrudes in a predetermined direction.
7 is formed horizontally. A notch 18 into which the lock piece 17 engages and disengages is formed at a predetermined position on one side of the recess 6 of the floor plate 1 by cutting from the back side. Here, this locking and its release are determined in relation to the direction of the slit 16. First, when the slit 16 is rotated with the coin 15 so as to match the moving direction of the lever 7, the lock piece 17 is moved into the notch 18.
to be locked. on the other hand.

The lock piece 17 is set to come off from the notch 18 when the slit 16 is rotated perpendicular to the moving direction of the lever 7. In this state, by sliding the lever 7 outward, the claw 8 is disengaged from the locking portion 9, and the cover assembly 4 is projected to the outside together with the outlet 3.

Thus, the floor plate 1 is attached to an outlet box 19 placed under the floor using attachment screws 20. Here, a box cover 2 having a round hole 21 is installed on the top of this outlet box 19.
2 is attached by screws 23. A screw hole 24 for direct fixing is formed in the coating margin around the round hole 21 of the box cover 22. Further, a scissor fitting 25 and a nut 26 held by the scissor fitting 25 are attached to the lower part of the floor plate 1, and the scissor fitting 25 has dimensions such that it fits into the round hole 21 of the box cover 22 in the free state. has been done. The nut 26 held by the scissors 25 and the screw hole 24 are in the same radial direction, with the nut 26 being on the inside.

The screw hole 24 is set on the outside.

The floor plate 1 has two screws for mounting screws 20.
holes 27 are formed. This hole 27 is formed as an elongated hole with a size that includes the nut 26 portion as the fixing position of the mounting screw 20 and the screw hole 24 portion, that is, the size that extends inside and outside the round hole 21 of the box cover 22. , whose interior is tapered and narrow. Further, a bushing 28 shaped to fit into this hole 27 is provided. Here, in order to ensure the fitting position between the hole 27 and the bushing 28, a rib 2 is provided between the hole 27 and the bushing 28.
9 and a recess 30 are formed as a pair. The bushing 28 has an eccentric insertion hole 31 for the mounting screw 20 formed therein.

According to such a configuration, first, the bushing 28 is inserted into the hole 2.
7, the insertion hole 31 is located inside the box cover 22 (on the side of the opening 2). It faces the nut 26 held by the metal fitting 25.

Therefore, by fitting the mounting screw 20 into the insertion hole 31 and tightening it, the mounting screw 20 will fit into the nut 26. As a result, as shown in the above-mentioned publications, the scissor fitting 25 holding the nut 26 is inserted into the round hole of the box cover 22 by tightening the mounting screw 20.
It can be expanded and installed within 1.

On the other hand, insert the bushing 28 into the hole 27 through its insertion hole 31.
If the fitting is done in such a way that is located on the outside, the insertion hole 31 will be in a position opposite to the screw hole 24 formed in the coating margin outside the round hole 21 of the box cover 22. Therefore,
By fitting the mounting screw 20 into the insertion hole 31 and tightening it, the mounting screw 20 is fitted into the screw hole 24.

As a result, the floor plate 1 can be directly mounted through the screw holes 24 of the box cover 22 by tightening the mounting screws 20.

In this way, according to this embodiment, the hole 27 of the floor plate 1
By changing the fitting direction of the bushing 28 and changing the mounting position, if the insertion hole 31 is placed inside, a fixing method using the scissors 25 can be adopted.
If the bushing 28 is fitted so that the edges are on the outside, it is possible to directly fix the box to the box using the screw hole 24.

In addition, by using such a bushing method, the insertion hole 31
The mounting part of the lower outlet box 19 can be seen through it, and the workability of the mounting process is improved.

Furthermore, even if the installation is changed later, loosen the mounting screw 20 from the nut 26 or screw hole 24, remove the bushing 28 from the hole 27, rotate the bushing 28, and then remove the bushing 28 from the hole 24.
Since all you need to do is change the fitting direction for bushing 2.
There is no need to remove the bushing 8 from the mounting screw 20, and there is no risk of losing the bushing 28 during construction.

In this embodiment, the floor plate 1 has an elongated hole 27.
However, it may be formed in a round hole shape as long as it has a size that includes the fixing positions of the plurality of mounting screws 20 such as the nut 26 and the screw hole 24. In this case as well, the hole may be formed in a round shape.

The insertion hole 31 for the mounting screw 20 may be formed eccentrically so that the bushing 28 can be fitted into the hole.

In addition, in this embodiment, since the explanation is based on an example of application to a floor outlet, the scissor metal fitting 25 method and the direct fixing method are selected, but different fixing methods at different positions can be adopted for other devices as well. If it can be obtained, it can be similarly applied.

Effects of the Invention As described above, in the present invention, a hole is formed in the main body of the device to a size that includes a plurality of fixing positions, and a bushing is provided in the hole to fit in a plurality of fixing positions, and the plurality of fixing positions are provided in the bushing. Since the insertion hole for the screw is formed eccentrically, the bushing can be installed to the hole in the device body simply by changing the position of the insertion hole, and it is possible to determine which fixed position the installation screw should be installed to. It can be easily selected and set, has a simple structure, and can be mounted in a desired manner.
