Description

[Detailed explanation of the invention] This invention is a modification of floor outlets installed on wooden floors.
Regarding this, when the middle cylinder with the outlet is stored inside the cylindrical part of the floor plate, the entire middle cylinder is covered by the outer cover and the lid to prevent electrical leakage caused by moisture under the floor. To provide a floor outlet for a wooden floor that prevents rodent damage, etc., and has a female screw on the inner peripheral surface of the outer cover so that a floor plate can be screwed onto this so that it can be easily and firmly installed on a wooden floor. The purpose is to provide

EMBODIMENT OF THE INVENTION Hereinafter, the specific structure of this invention will be explained in detail based on the illustrated Example.

The floor outlet for wooden floors of the present invention includes an outer cover 6 with an opening on the upper surface, which is made up of a bottom plate 3 having an outlet 2 for the lead wire 1, a cylindrical peripheral wall 5 having a female screw 4 on the inner peripheral surface, and A male screw 7 corresponding to the female screw 4 of the outer cover 6 is provided on the outer circumferential surface of the cylindrical portion 8, and a flange portion 1 abuts against the floor surface 9 on the upper part.
a floor plate 11 in which 0 are connected in series; a middle cylinder body 13 having an outlet 12 loosely inserted into the cylindrical part 8 of the floor plate 11; a coil spring 16 installed between the spring receiver 14 and a spring receiver groove 15 annularly provided at the lower end of the middle cylinder 13; and a top surface of the middle cylinder 13. The cover body 17 is fixed to the cover body 17.

First, the outer cover 6 is made up of a cylindrical peripheral wall 5 and a bottom plate 3, and is open at the top.The bottom plate 3 has an outlet 2 for the lead wire 1 in the approximate center thereof, and a rubber bush 18 at the periphery of the outlet 20. Insert.

Further, the cylindrical peripheral wall 5 has a diameter that can be fitted into a mounting hole opened in the floor surface 9, and a female screw 4 is provided approximately at the center of its inner peripheral surface.

Next, the floor plate 11 includes the cylindrical portion 8 and the flange portion 10.
A male screw 1 corresponding to the female screw 4 of the outer cover 6 is provided at the lower part of the outer peripheral surface of the cylindrical portion 8.

In addition, a wood screw 1 is attached to the floor surface 9 at an appropriate place on the upper surface of the flange portion 10.
A small hole is drilled for screwing 9.

The inner cylindrical body 13 equipped with the outlet 12 is loosely inserted into the cylindrical part 8 of the floor plate 110, and has a locking protrusion 20 protruding from the outer periphery of the flat end. The protrusion 20 comes into contact with and is locked to a stopper 21 protruding from the inner peripheral surface of the portion 8, and when the inner cylinder 13 is turned, the engagement with the stopper 21 is released. It looks like this.

Note that the spring receiver 14 provided at the lower end of the cylindrical portion 8 of the floor plate 11 and the spring receiver provided at the lower end of the middle cylindrical body 13 are activated by the elastic force of the coil spring 16 installed between the groove 15. The middle cylindrical body 13 is designed to protrude above the floor surface 9, and the middle cylindrical body 13 is pressed downward against the elastic force of the spring 16, and the protrusion 20 is latched to the stopper 21 described above. If you do this, it will be in the stored state.

In addition, 22 in the figure is a mounting screw for fixing the lid body 17 to the upper surface of the middle cylinder body 13.

The present invention has the above-mentioned structure, and when installing, the cylindrical part 8 of the floor plate 11 is inserted into the outer cover 6,
At the same time as screwing together, the outer cover 6 is inserted into the round mounting hole made in the floor surface 9, the flange portion 10 of the floor plate 11 is brought into contact with the floor surface 9, and it is fixed to the wooden floor with wood screws 19. When using the outlet 12, the lid 17 is rotated using the knurling cut on the outer periphery of the lid 1γ as a guide, and the protrusion 20 of the middle cylinder 13 is disengaged.
3 protrudes above the floor surface 9.

Note that since the upper end of the cylindrical portion 8 of the floor plate 11 has a stepped portion 23 that protrudes inwardly, the middle cylindrical body 13 protrudes to a predetermined height and is locked.

The floor outlet for wooden floors of the present invention has the above-mentioned structure and function, and when the inner cylinder with the outlet is housed inside the cylindrical part of the floor plate, the entire middle cylinder is completely covered by the outer cover and the lid. Since it is covered, it is possible to completely prevent electrical leakage and rodent damage caused by moisture under the floor.

In addition, the cylindrical part of the floor brake (7') is screwed onto the inner circumference of the outer cover, and the flange part of the floor plate is fixed to the wooden floor, making installation extremely easy and providing a sturdy floor outlet. can be provided.
