Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a floor outleft for taking out a telephone line or the like from the floor or providing an outlet.

[Conventional technology]

As an outleft for extending telephone wires that has been commercially available and widely used, there is one shown in FIG. 9. This floor outlet includes a base 52 disposed on the floor 51,
The base 52 has a cylindrical threaded portion 5 provided in a floor duct, etc. under the floor surface.
4 is screwed on. The outer box 53 is provided with an outlet 55 for electrical wires such as telephone lines, and a packing 5 for preventing rotation.
8 on the floor 51. In this state, insert the fixing screw 56 from the top surface of the outer shell 53 into the screw hole 5 of the base 52.
7 and tighten, the outlet 55 is fixed to the floor 11 in any direction.

[Problem to be solved by the invention]

However, this traditional floor outlet has a packing of 5
Since rotation is only stopped by the frictional force of 8, there is a problem that the direction of the outlet 55 changes if it is kicked by a person or hit by an object.

An object of the present invention is to provide a floor outlet that does not easily change direction even when hit by a person's feet or equipment.

[Means to solve the problem]

This invention provides a base with a threaded tube protruding from the lower surface of the mounting plate, screws the screw tube into the threaded portion of the wiring member under the floor surface, and connects the outer shell covering the base to the floor surface through the packing. In this floor outlet, the outer shell is placed on the floor and is fixed in a pressed state against the floor by a fixing screw screwed into the base, and the lower surface of the outer shell is provided with a rotation preventing protrusion that penetrates through the packing.

[Effect]

According to the configuration of the present invention, by tightening the fixing screw, the packing is drawn to the outside or the base and pressed together with the packing onto the floor surface. Due to the force of this pressing, the anti-rotation protrusion on the lower surface of the outer cover penetrates the packing and bites into the floor surface. This biting prevents rotation of the outer shell, and rotation is also prevented by the frictional force of the packing.

[Embodiment] A first embodiment of the present invention will be described based on FIGS. 1 to 7.

This floor outlet consists of a base 1, an outer frame 2, a decorative board 3, a rotation stopper banking 4, and a fixing screw 5.

The base 1 consists of a threaded cylinder 1a that is screwed onto the insert threaded part 6 of the floor duct 7, which is a piping member, and a mounting plate part 1b located on the upper surface of the floor 9. A screw hole 1C for screwing the fixing screw 5 is provided in the boss portion 1d.
is the provision. The screw holes 1c are provided at two locations corresponding to the diameter of the base 1.

The outer shell 2 is formed into a short cylindrical shape, and mounting seats 2a having screw insertion holes 2b into which the fixing screws 5 are inserted protrude from two locations on the inner surface. An inverted U-shaped outlet 2f for pulling out electric wires such as telephone lines is formed in the circumferential body of the outer shell 2 by cutting out from the lower end thereof. The outlet ports 2f are provided at one to four locations in the circumferential direction so as not to interfere with the mounting seat 2a. An annular protrusion 2 is provided on the lower end surface of the outer shell 2 to fit into the circumferential groove 4a on the upper surface of the banking 4, and a rotation preventing protrusion 2e is provided on the lower surface of the annular protrusion 2C. As shown in FIG. 2, the rotation stopper projection 2e has a triangular shape and is provided at the same circumferential position as each mounting seat 2a. Therefore, the rotation stopper projections 2e are provided at two locations in the circumferential direction.

As shown in FIGS. 4 and 5, the packing 4 is ring-shaped with a circumferential groove 4a formed on the upper surface, and holes 4b into which the rotation stopper projections 2e are inserted are provided on the bottom surface of the circumferential groove 4a. be. The hole 4b has a membranous bottom 4c, and the fixing screw 5 can be tightened from the outside 2 at the front, as shown in FIG.
The rotation stopper protrusion 2e is housed in the hole 4b. In addition,
The hole 4b may be a through hole. Further, as shown in FIG. 1, the packing 4 is formed with a U-shaped portion 4d that fits into the outlet 2f of the outer shell 2.

The decorative board 3 is formed into a disk shape with an outer diameter equal to the outer diameter of the upper surface of the outer shell 2, and is attached to the outer shell 2 by an elastic engagement piece (not shown) or the like.

The construction procedure for the above configuration will be explained. First, screw the base 1 onto the insert screw part 6 of the floor duct 7, and cover the base 1 with the outer shell 2 so that the electric wire (not shown) of the floor duct 7 can be pulled out from the outlet 2r of the outer shell 7. . The packing 4 is fixed to the outer shell 2 with adhesive or the like in advance. After that, the fixing screw 5 is inserted into the screw insertion hole 2b of the outer shell 2, screwed into the screw hole IC of the hess 1, and after tightening, the decorative board 3 is attached to the outer shell 2.

When the fixing screws 5 are tightened, the outer paddle 2 is drawn toward the base 1 and pressed against the floor 9. Therefore, the packing 4 is compressed and the rotation stopper protrusion 2 of the outer paddle 2
e breaks through the bottom 4c of the hole 4b of the packing 4, and the floor 9
(Figure 7). If the finishing material of the floor 9 is vinyl tile or the like, it will easily dig in. This biting provides a rotation preventing force, and in combination with the frictional force of the packing 4, the outer gear 2 can be reliably stopped from rotating. Therefore, even if it is kicked or hit by an object, the outer drawer 2 will not change the direction of the drawer opening 2f. In this embodiment, the rotation stopper projection 2
e is arranged at the same position in the circumferential direction as the fixing screw 5, so that force is easily transmitted when tightening the fixing screw 5, and the rotation stopper protrusion 2eV (1) can be bitten into the fixing screw 5.

FIG. 8 shows another embodiment. This example is an example in which the present invention is applied to a floor outleft in which the outlet 10 is housed in the outer enclosure 2. A reinforcing plate 11 is arranged on the upper surface of the outlet 10, and the outlet 10 is held down by the reinforcing plate 11 by tightening with a fixing screw 5 together with the outer cover 2. The outlet 10 is fitted into the outlet 2f of the outer box 2 to expose the front surface. The other configurations are the same as those in the first embodiment, and corresponding parts are given the same reference numerals and explanations thereof will be omitted.

In this configuration as well, the outer paddle 2 can be reliably prevented from rotating by the rotation preventing protrusion 2e in the same manner as described above.

In the above embodiment, the packing 4 is ring-shaped, but the packing 4 may be divided into a plurality of parts in the circumferential direction, and the rotation stopper projections 2e may be arranged in the divided parts. The shape of the rotation stopper projection 2e may be a cone, a pyramid, or the like. The number of rotation stopper projections 2e may be one, or three or more.

Further, in the above embodiment, the floor outlet is installed in the floor duct 7, but this floor outlet can also be attached to a threaded portion of a floor box or the like embedded in the floor 11.

[Effects of the Invention] In the floor layouts 1 to 3 of this invention, in the floor layout trend in which the deck is placed on the floor through packing and the deck is fixed to the base with fixing screws, the floor tray is rotated on the underside of the deck. Since the stop protrusion is provided, by tightening the outer shell to the base with the fixing screw, the outer shell is pushed toward the floor surface, and the rotation stop protrusion bites into the floor surface. Therefore, combined with the frictional force of the packing, it is possible to reliably stop the outer shell from rotating, and it has the effect that it will not easily change direction even if it is kicked by someone or hit by an object.
