BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor outlet fixing ring for holding a floor outlet fixed on a carpet floor in a stable state for a long period of time.

[0002]

2. Description of the Related Art In recent years, a carpet is often attached to the floor surface in order to improve the habitability of the work space.
Therefore, when installing the floor outlet, the floor cylinder ring, which is a mounting flange plate exposed on the floor, is fixed to the floor surface side with the carpet sandwiched therebetween. FIG. 4 is a cross-sectional view showing how to install a floor outlet when the floor cylinder ring is of a screw type. An outlet box 5 having a floor base 3 attached to the upper surface is embedded in the concrete floor 1, and a horizontal adjustment ring 7 having a screw formed on the inner circumference is attached to the center of the floor base 3. A floor cylinder 11 having an outlet movable portion 9 therein is screwed into the inner periphery of the horizontal adjustment ring 7, and the floor cylinder 11 has a floor cylinder ring 13 formed at the upper end thereof exposed on the floor surface. Is becoming That is, the floor cylinder ring 13 presses the floor surface by being screwed into the leveling ring 7,
The carpet 15 is fixed to the floor while being sandwiched between the floor and the floor.

FIG. 5 is a cross-sectional view showing how the floor outlet is mounted when the floor cylinder ring is of the screw fixing type. Floor base 19 of outlet box 17
A horizontal adjustment ring 21 is attached to the horizontal adjustment ring 21, and a fixing piece 23 located below the floor surface is formed on the outer periphery of the upper end of the horizontal adjustment ring 21. A floor cylinder 25 is inserted into the horizontal adjustment ring 21 attached to the floor base 19, and a floor cylinder ring 27 is formed at the upper end of the floor cylinder 25. And the leveling ring 2
By inserting the floor cylinder 25 into 1, the floor cylinder ring 27 faces the fixing piece 23.
A screw hole is formed in the floor cylinder ring 27, and a screw 29 inserted in the screw hole is screwed into the fixing piece 23. That is, the floor cylinder ring 27 is fixed to the floor side in a state where the floor surface is pressed by the screw 29 being screwed into the fixing piece 23 and the carpet 15 is sandwiched between the floor surface and the carpet 15 as described above. -ing In this manner, the floor cylinder rings 13 and 27 are fixed in a state where the carpet 15 is sandwiched between the floor surface and the floor surface, the pressing force is retained, and the reaction force thereof prevents the loosening.

Further, a loosening prevention washer may be inserted between the floor cylinder ring and the carpet 15 in order to prevent the floor cylinder ring from loosening. The locking washer has a claw protruding from the lower surface side of the carpet, and the floor cylinder ring is tightened to press the floor surface so that the claw is fixed to the carpet. Therefore, the floor cylinder ring presses the loosening prevention washer, and its relative rotation is restricted by friction with the loosening prevention washer fixed and fixed, so that the loosening is stopped and fixed.

[0005]

Conventionally, when the carpet 15 is laid on the floor surface, the fixing of the floor outlet is
While the carpet 15 was sandwiched between the floor surface and the floor surface, the pressing force of the floor cylinder rings 13 and 27 was maintained, and the reaction force of the floor cylinder rings 13 and 27 prevented the loosening of the carpet, and the carpet 15 was fixed. However, depending on the fabric characteristics of the carpet 15, the waist (elasticity) may decrease over time, and in such a case, the reaction force against the floor cylinder rings 13 and 27 does not occur and the carpet 15 cannot be sandwiched, and the floor cylinder ring is 13, 2
There was a case where 7 was loosened. For this reason, it is difficult to maintain a stable fixed state for a long period of time, and it is necessary to confirm the fixed state by maintenance and to perform retightening for the purpose of preventing accidents such as electric leakage due to loosening.

[0006] In addition, there is a structure in which a loosening prevention washer is used for the purpose of structurally preventing loosening, and the loosening prevention washer itself is fixed to a carpet, and the floor cylinder ring is prevented from loosening by friction with the loosening prevention washer. ,
Since the lock washer and the floor cylinder ring are fixed only by the friction due to the pressing force, when the elasticity of the carpet deteriorates over time, a sufficient reaction force does not occur and the friction force is reduced. There was a risk of loosening.

The present invention has been made in view of the above circumstances, and provides a floor outlet fixing ring that does not cause the floor cylinder ring to loosen even if the elasticity of the carpet deteriorates over time, thereby eliminating maintenance work for loosening prevention. ,
The purpose is to prevent accidents due to loosening.

[0008]

The floor outlet fixing ring according to the present invention for achieving the above object is to be inserted between a mounting collar plate of a floor cylinder and a carpet when the floor cylinder is attached to an outlet box. In this case, a claw for fixing to the carpet is projected on one surface of the plate-shaped ring, a fixing hole is formed in the mounting flange plate of the floor cylinder, and the screw inserted in this fixing hole is It is characterized in that a screw hole to be screwed is formed in the ring.

[0009]

[Function] The floor outlet fixing ring (fixing ring) is inserted into the floor cylinder, the floor cylinder is screwed into the outlet box, and the mounting flange plate of the floor cylinder rotates the fixing ring while rotating relative to the separate fixing ring. It is fixed to the carpet by pressing it toward the carpet and fixing the claws to the fixing ring. By properly rotating the floor cylinder, the fixing holes of the mounting flange plate are aligned with the screw holes of the fixing ring, and the screws inserted in the fixing holes are screwed into the screw holes, so that the fixing ring and the mounting flange are screwed together. The board and the floor cylinder are fixed together, and the loose rotation of the floor cylinder is restricted via a fixing ring fixed to the carpet.
