Description

[Detailed description of the invention] [Industrial field of application] The present invention relates to the improvement of a washer used when fixing a floor outlet installed on the floor of an office to a floor member, and is particularly suitable for use with raised floors. The present invention relates to a washer for a floor outlet suitable for use when installing a floor outlet on a double floor.

[Conventional technology]

OA equipment such as word processors, fax machines, office computers, and copiers has increased in offices.
In order to handle the wiring for these OA equipment, a floor component consisting of a floor panel, etc. is further laid on top of the conventional basic floor surface, and cables are run through the space created between the basic floor and the floor panel. A raised access floor is being constructed. When constructing this raised floor, if the space between the base floor and the floor panel is set too large, the height from the floor to the ceiling will become low, which will worsen the office environment. There is a reason that it cannot be made too large.

On the other hand, cables running in the space between the basic floor and the floor panel are generally taken out via a floor outlet, but when installing this floor outlet to a floor component, conventionally An outlet box or the like is placed at the bottom of the floor plate, the outlet lead wire and cable are connected within the outlet box, and a tightening ring is screwed onto the cylindrical part of the floor plate via a washer. Therefore, a method is used in which the floor plate is fixed to the floor member using the tightening ring and washer.

[Problem that the invention attempts to solve]

As mentioned above, conventionally, the connection between the outlet lead wire and the cable was made inside the outlet box placed at the bottom of the cylindrical part of the floor plate, so the thickness of the outlet box caused problems. Therefore, there is a problem in that when there is not enough height from the basic floor to the floor panel, it is virtually impossible to attach the floor plate to the floor panel.

In addition, since the outlet box was placed at the bottom of the floor plate, the height from the floor panel to the ceiling was reduced by that amount, creating a poor office environment.

The purpose of the present invention is to eliminate the above-mentioned conventional problems by extending one side of the washer used when attaching the floor plate to the floor panel to form a tongue piece, and attaching the outlet lead wire and cable to the tongue piece. To provide a washer for a floor outlet, on which a connection terminal for connection with a floor plate is attached, and an outlet box at the bottom of a floor plate, which was conventionally indispensable, can be removed.

[Means for solving problems]

To explain in detail the structure of the present invention to solve the problem, there is a floor plate which is equipped with an outlet inside and has a flange-like part connected to the upper surface of a cylindrical part with a screw groove carved on the outer circumferential surface. A washer for a floor outlet used when fixing to a floor member,
A tongue piece is formed by extending one side of the washer member main body, which has a through hole in the center that is large enough to fit the cylindrical part of the floor plate, and the outlet socket is attached to the tongue piece. A washer for a floor outlet, characterized in that a connection terminal for connecting a lead wire and a cable is attached, and a tongue piece is provided with a step extending to one side of the washer member body, and the lower surface of the tongue piece is provided. By attaching a connecting terminal to the floor outlet, it is possible to provide a washer for a floor outlet with good operability.

Therefore, according to the present invention, the outlet box at the bottom of the floor plate, which was indispensable in the past, is no longer necessary, and the space between the basic floor and the floor panel can be narrowed by that much, and the distance from the floor panel to the ceiling can be reduced accordingly. Since the height of the floor can be set to a sufficient height, it has a great effect on improving the office environment.

〔Example〕

EMBODIMENT OF THE INVENTION Hereinafter, the specific structure of this invention is demonstrated in detail based on the illustrated Example.

Fig. 1 is an exploded perspective view of the floor outlet washer of the present invention, a floor plate, and a tightening ring, and Fig. 2 is a vertical sectional view showing an example of the usage state of the inventive floor outlet washer. A floor member made of a panel material or the like is shown, which is laid on the upper surface of a basic floor 2 such as a concrete slab while maintaining a predetermined space 3. A cable 4 for supplying power to OA equipment is wired within a space 3 formed between the floor member 1 and the basic floor 2.

Attachment holes 5 are drilled in predetermined locations in the floor member 1, and a floor plate 6 installed in the attachment holes 5 is equipped with an outlet 7 inside, and
It is equipped with a cylindrical part 8 having a threaded groove carved on its outer peripheral surface, and a flange-shaped part 9 extending perpendicularly to the cylindrical part 8 on the upper surface of this cylindrical part 8. The structure is such that the lower surface is in contact with the upper surface of the floor member 1.

Then, the lower surface of the brim portion 9 is brought into contact with the upper surface of the floor member 1, and the tightening ring 11 is screwed through the washer member main body 10 from the lower side of the cylindrical portion 8 inserted into the mounting hole 5. , the floor plate 6 is fixed to the floor member 1 by the washer member main body 10 and the tightening ring 11.

As shown in FIG. 1, the washer member main body, indicated by 10 in the figure, has a through hole 12 having a size in which the cylindrical portion 8 of the floor plate 6 can be inserted, approximately in the center thereof. A tongue piece 15 is formed on one side thereof to attach a connecting terminal 14 for connecting the lead wire 13 of the outlet 7 and the cable 4.

This tongue piece 15 is an extension of one side member of the washer member main body 10, but in order to improve the operability in use, one side part of the washer member main body 10 is bent downward, and It is preferable that a horizontal portion is extended perpendicularly to this bent portion to form the tongue piece 15.

The connection terminal 14 has a normal structure with a terminal insertion opening opened only on one side, and when it is attached to the lower surface of the tongue piece 15, a screw 17 is screwed in from the outside of the cover body 16. , may be screwed to the tongue piece 15, or may be attached to the tongue piece 15 using an adhesive.

Regarding the structure of the floor outlet, in the illustrated embodiment, a middle cylinder that can protrude upward by the elastic force of a spring 18 is provided in a cylindrical part 8 having an outer diameter that can be loosely fitted into the mounting hole 5. A body 19 is attached, and the outlet 7 is disposed within this inner cylindrical body 19.
When a coin or the like is inserted into the groove formed in the upper surface of the lid body 20 and turned, the engagement of the middle cylinder body 19 in the cylindrical part 8 is released, and the middle cylinder body 19 is moved to the floor by the spring 18. Although the structure of the floor outlet is such that it projects upward from the plate 6, the structure of the floor outlet in which the washer member of the present invention can be used may be other than the type that projects upward as in this illustrated embodiment. Of course.

When using the floor outlet washer of the present invention, the cylindrical part 8 of the floor plate 6 is inserted into the mounting hole 5 opened in the floor member 1, and the lower surface of the brim part 9 is inserted into the mounting hole 5 of the floor member 1. Lock it against the top surface.

Next, the washer member main body 10 and the tightening ring 11 are inserted into the space 3 through another hole opened in the floor member 1, and the washer member main body 10 is fitted from the lower side of the cylindrical part 8 and tightened. The ring 11 is screwed onto the cylindrical portion 8. Then, the floor plate 6 is sandwiched between the washer member main body 10 and the brim portion 9, and can be firmly fixed to the floor member 1.

Then, by inserting the tip of the lead wire 13 of the outlet 7 and the tip of the cable 4 into the terminal hole of the connection terminal 14, an electrical connection between the two is achieved.

[Effect of idea]

The floor outlet washer of the present invention has the above-mentioned configuration and function, and can connect the outlet lead wire and cable with a simple operation.
Since there is no need to use an outlet box at the bottom of the floor plate as in the conventional case, it is possible to set the space between the base floor and the floor member narrower. Therefore, according to the present invention, it is possible to construct a raised floor by narrowing the space between the base floor and the floor components compared to the conventional method, and the height from the floor components to the ceiling is less affected. , it also has a great effect on improving the office environment. Further, according to the present invention, there is an advantage that the floor plate can be attached to the floor member even if there is not much margin in the height from the basic floor to the floor member.
