Description

Description: FIELD OF THE INVENTION The present invention relates to floor outlets.

Conventional technology and problems to be solved by the invention Conventionally, in the case of floor outlets (floor-embedded outlets), the floor plate is attached and fixed to the outlet box under the floor. Gazette, Shokai 57
There are mounting methods such as those disclosed in Japanese Patent Publication No. -45789 and Japanese Utility Model Publication No. 55-173229. In other words, a method of attaching using scissors and nuts (fixing method using scissors)
There is also a method of directly attaching to the screw hole formed in the box coating cover of the outlet box (direct fixing method). However, in the case of the conventional type, the fixing method using the scissors metal fittings can be attached only by the scissors metal fittings. This is because the size is set such that the mounting screws are returned to the inside through the round holes of the outlet box, and thus the interval between the mounting screws is smaller than the interval between the round holes of the box. For this reason, the box cover is provided with a protrusion protruding toward the round hole to directly form the mounting screw hole,
It allows direct attachment, and when using scissors, this convex portion is cut out or bent.

In addition, as described in Japanese Utility Model Publication No. 50-16237, a long hole into which a mounting screw is inserted is provided in the device mounting frame as a device which can be mounted by adjusting the position of the device mounting frame. There is one in which a plurality of protrusions are formed on the inner periphery of the elongated hole so that the mounting screws can be fitted at different positions. However, when using this type for a floor outlet, it is not possible to select between a fixing method using scissors and a direct fixing method. Further, Japanese Utility Model Application Laid-Open No. 57-20308 discloses a boss-shaped washer having an eccentric hole, which is effective when it is used to fix two parts whose mounting holes are misaligned. Yes, the washer is moved to match the screw hole with the other party. Therefore, also in this case, when it is attempted to use it for a floor outlet, it is impossible to select between the fixing method using scissors and the direct fixing method.

Therefore, an object of the present invention is to obtain a floor outlet capable of easily selecting and installing different mounting methods such as a fixing method and a direct fixing method using scissors.

MEANS FOR SOLVING THE PROBLEMS The present invention includes an outlet body 4 and a plate 1 having an opening 2 in the center thereof capable of projecting and retracting the outlet body 4, and the peripheral side of the plate 1 is placed on a floor surface for mounting. In the floor outlet, a long hole 27 having a taper surface that expands to the front side in a size including a plurality of fixed positions in the direction along the peripheral direction from the central portion of the plate 1 is formed. A bushing 28 having a tapered surface corresponding to that of the slot 27 and having a size substantially the same as that of the slot 27, and provided with a bushing 28 that fits in the slot 27 at a plurality of mounting positions, and the bushing 28 is formed eccentrically. A mounting screw 20 is provided which is mounted in the hole 31 and is positioned at a fixed position selected according to the mounting position of the bushing 28.

The elongated hole 27 formed in the plate 1 has a size including a plurality of fixing positions, and the bushing 28 fitted into the elongated hole 27 has the insertion hole 31 for the mounting screw 20 formed eccentrically. By simply changing the fitting direction of the bushing 28 with respect to the long hole 27 and changing the position of the insertion hole 31, it is easy to select whether the mounting screw 20 is to be mounted with scissors or directly. It becomes possible to set.

Embodiment An embodiment of the present invention will be described with reference to the drawings. First, an outline of the floor outlet will be explained. First, the plate 1 arranged on the floor has a circular opening 2 in the center, and at the lower part of the opening 2, an outlet main body 4 integrally incorporating an outlet 3 is provided. . The outlet main body 4 is rotatable about a shaft 5 like the one shown in the above-mentioned publication, and is biased upward by a torsion spring or the like (not shown), as shown by a chain line in FIG. The outlet 3 is exposed to the outside through the opening 2. A recess 6 is formed in a part of the plate 1, and a lever 7 is provided in the recess 6 so as to be movable back and forth in the radial direction. A claw 9 that engages and disengages with the locking portion 8 of the outlet main body 4 is attached to the tip of the lever 7 on the side of the opening 2 with a screw 11 via a spacer 10, and a long hole 12 that guides the advance / retreat is formed. It is formed on the plate 1. In such a lever 7, the operation cylinder body 13 is slightly moved to one side
It is rotatably arranged by 14. This operating cylinder 13
A slit 16 that can be rotated by a coin 15 is formed on the top of the. Further, on the lower side of the operation cylinder body 13, a lock piece 17 which is projected in a predetermined direction is horizontally formed. A notch 18 for engaging and disengaging the lock piece 17 is formed at a predetermined position on one side of the recess 6 of the plate 1 by cutting from the back side. Here, this lock and its release are set in association with the direction of the slit 16. First, slit 16 to coin 15
When the lever 7 is rotated so as to match the moving direction of the lever 7, the lock piece 17 is locked in the notch 18. On the other hand, when the slit 16 is rotated so as to be orthogonal to the moving direction of the lever 7, the lock piece 17 is set to be disengaged from the notch 18. In this state, by sliding the lever 7 outward, the claw 8 is disengaged from the locking portion 9 and the outlet body 4 is projected outward together with the outlet 3.

Thus, the plate 1 is attached to the outlet box 19 arranged under the floor by the attaching screw 20. A box cover 22 having a round hole 21 is attached to the upper portion of the outlet box 19 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 scissors 25 and a nut 26 held by the scissors 25 are attached to the lower portion of the plate 1, and in a free state, the scissors 25 are sized to fit into the round holes 21 of the box cover 22. There is. This scissors metal fitting 25
The nut 26 and the screw hole 24 held by the screw hole 24 are set so that the nut 26 is on the inner side and the screw hole 24 is on the outer side in the same radial direction. The plate 1 has a mounting screw 20
Two long holes 27 are formed. This long hole 27. It is formed as a long hole of a size that includes the nut 26 portion and the screw hole 24 portion as the fixing position of the mounting screw 20 (that is, the size that extends inside and outside the round hole 21 of the box cover 22), and the inside thereof. Are tapered so as to narrow. In addition, a bushing shaped to fit in this long hole 27
28 are provided. Here, in order to ensure the fitting position between the long hole 27 and the bushing 28, the rib 29 and the recess
30 and 30 are formed in pairs. And this bushing 28
An insertion hole 31 for the mounting screw 20 is eccentrically formed in the.

According to this structure, first, the bushing 28 is formed in the long hole 27.
With respect to the insertion hole 31, if the mounting position is set such that the insertion hole 31 is located inside (the opening 2 side), the insertion hole 31 comes into the round hole 21 of the box cover 22, and the scissors 25 Will face the nut 26 held by the. Therefore, the mounting screw 20 is fitted into the nut 26 by mounting the mounting screw 20 in the insertion hole 31 and tightening it.
As a result, as shown in the above-mentioned publications, the scissors metal fitting 25 holding the nut 26 by tightening the mounting screw 20.
Is installed by expanding it in the round hole 21 of the box cover 22.

On the other hand, if the bushing 28 is fitted into the elongated hole 27 as a mounting position such that the insertion hole 31 is located outside, the insertion hole 31 is a screw formed in the coating margin outside the round hole 21 of the box cover 22. The position is opposite to the hole 24. Therefore, by attaching the mounting screw 20 to the insertion hole 31 and tightening it, the mounting screw 20
Will be fitted into the screw hole 24. As a result, the plate 1 is directly mounted by the screw holes 24 of the box cover 22 by tightening the mounting screws 20.

As described above, according to the present embodiment, by changing the fitting direction of the bushing 28 with respect to the long hole 27 of the plate 1 to change the mounting position so that the insertion hole 31 is on the inner side, the fixing method by the scissors metal fitting 25 is adopted. If the bushing 28 is fitted so that the insertion hole 31 is on the outside, a direct fixing method to the box by the screw hole 24 can be adopted. Further, by such a bushing system, the mounting portion of the lower outlet box 19 and the like can be seen through the insertion hole 31, and the workability of mounting is improved. Further, even if the change is made after the mounting, the mounting screw 20 is loosened from the nut 26 or the screw hole 24, the bushing 28 is pulled out from the long hole 27, and the bushing 28 is rotated to change the fitting direction to the long hole 27. Since it is only necessary to change the bushing 28, it is not necessary to remove the bushing 28 from the mounting screw 20, and there is no risk of the bushing 28 being lost during construction.

As described above, the present invention is a floor outlet provided with an outlet main body and a plate having an opening at which the outlet main body can be retracted in the center, and the peripheral side of this plate is mounted on the floor surface. The plate, a long hole having a tapered surface that expands to the front side in a size including a plurality of fixed positions in a direction along the peripheral direction from the central portion is formed, and a tapered surface corresponding to the tapered surface of the long hole is formed. And a bushing that is approximately the same size as the long hole and is fitted in the long hole with a plurality of mounting positions.The bushing is attached eccentrically to the bushing and is attached according to the mounting position of the bushing. Since the mounting screw positioned at the selected fixed position is provided, the long hole formed in the plate has a size including a plurality of fixed positions, and the fitting hole fitted in the long hole is formed. Since the insertion hole for the mounting screw is eccentrically formed in the single, the mounting screw can be fixed by a scissors bracket by simply changing the position of the insertion hole by changing the fitting direction with respect to the long hole of the bushing.
