Description

[Detailed Description of the Invention] [Purpose of the Invention] (Field of Industrial Application) The present invention relates to an electrical outlet, and particularly to an electrical outlet that can be used by extending a cord from the wall surface to which it is attached.

(Prior Art) In general, an electrical outlet has a jack part embedded inside a wall surface, and a plug connected to the tip of a cord on the side of an electric appliance is inserted into the jack on the wall surface.

(Problem to be solved by the invention) As is clear from the above explanation, the installation position of the outlet is fixed, so depending on the position where the appliance is used, for example, there may be insufficient cords, giving freedom of use. It has a small drawback.

The present invention has been made in view of the above circumstances, and aims to provide an outlet whose range of use can be expanded to a certain extent regardless of the installation position of the outlet.

[Structure of the invention] (Means for solving the problem) The present invention uses a rectangular three-dimensional case that forms the outlet body and a screw installed inside the case in an outlet that can be used by pulling out the cord. a body part which is movable by being screwed onto a shaft having the body; a base which is rotatably integrally engaged with the body part; and a spiral shaped body which is provided within the base and provides a repulsive force to the rotation of the body part. It consisted of a spring, and a cord that was wound around the body, had an insertion port at one end, was drawn out of the wall surface, and had its other end connected to a ring-shaped electrode provided on a base.

(Function) When the insertion port is pulled out, the cord is pulled out while rotating the body against the spiral spring. in this case,
The body rises according to the pitch of the shaft screw,
The cord is always wound in a position corresponding to the drawer opening, allowing for smooth drawout.

On the other hand, when storing the cord, if the force applied to the cord is relaxed, the cord will be entangled by the restoring force of the torso.

(Example) Examples will be described below with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of an electrical outlet according to the present invention, and is shown as a side sectional view in an installed state.

In FIG. 1, reference numeral 1 denotes an outlet main body, which is fixed inside a wall surface 2. Reference numeral 3 denotes a housing having a rectangular parallelepiped shape, and a shaft 4 is fixed at the center of the housing, and this shaft 4 is provided with a screw. Reference numeral 5 denotes a cylindrical body, which is integrally constructed by being rotatably engaged with a rectangular base 6 at its lower end (described later).

A cord 7 is wound around the body 5, and one end of the cord 7 is connected to an outlet (corresponding to a jack) 8, and can be pulled out through an outlet 9. The end is connected to the indoor distribution cable 10 via the base 6.

The body portion 5 is screwed together with the shaft 4,
In response to the pulling operation of the insertion port 8, the body 5 rotates and rises, so that the cord is pulled out from the body 5 at the following position:
It is always set at the position of the drawer opening 9 depending on the drawer.

FIG. 2 is a partially cutaway perspective view of the body 5, showing how the cord 7 is wound around the outer periphery of the body 5, and FIG. 3 shows the connection between the base 6 and the body 5. A partially cutaway cross-sectional view is shown.

In FIG. 2, reference numeral 11 denotes a protrusion provided on the periphery of the body portion 5, which engages with a recess 12 provided on the circular inner periphery of the base 6, as shown in FIG.

An elastic contact piece 1 is provided on the bottom plate 15 of the body 5.
3 and 14 are provided, of which the contact piece 13 contacts the ring-shaped electrode 16, and the contact piece 14 also contacts the ring-shaped electrode 17, and is configured to oscillate.

That is, a partition wall 18 is provided inside the base 6 having a rectangular shape, a ring-shaped electrode 16 is provided on one side of the partition wall 18, and a ring-shaped electrode 17 having a smaller diameter than the electrode 16 is arranged concentrically. Each wiring from the cable 10 is connected to each of these electrodes to serve as a power source.

Reference numeral 19 denotes a frame bar protruding from the bottom plate 15, and a spiral spring 20 is provided between this frame bar and the base.

That is, when the trunk 5 rotates via the protrusion 11,
When the spiral spring 20 is tightened and there is no rotational force on the body 5, the force of this spring causes the body 5 to
A force acts to return it to its original position. In addition, the first
21 in the figure is a cover.

Next, I will explain how it works.

First, since no force is normally applied to the body 5, the cord 7 is retracted by the force of the spiral spring 20 inside the base 6, and the body 5 is located at the lowest part of the housing 3.

Now, when using the cord, when a force is applied in the direction of the arrow in FIG. 1 against the force of the spiral spring 20, the body 5 rotates and the shaft 4 is raised.

In this case, the body 5 rotates separately from the base 6 via the protrusion 11, but as the body 5 rises, the base 6
The inner wall of the casing 3 rises integrally with the body 5.

For the rise of the trunk 5, the cord allowance 22
(Figure 3). Note that locking after the cord has been pulled out to a predetermined length is performed using a conventionally known configuration.

While the body 5 rotates and rises according to the pitch of the screw of the shaft 4, the contact pieces 13 and 14 continue to oscillate while maintaining contact with the ring-shaped electrodes 16 and 17.
Power supply is secured.

The state in which the cord 7 is pulled out is shown in FIG. 4. When the cord is unlocked after use, the body 5 is lowered by the restoring force of the spiral spring 20.
Return to the state shown in FIG.

Although the insertion port 8 is shown to protrude in FIG. 1, it is also possible to embed it inside the cover 21.

[Effects of the invention] As explained above, according to the invention, since the cord stored inside the wall can be pulled out and used, the range of use as an outlet is expanded, and the drawer and storage can be easily carried out. It becomes possible.
