Description

[Detailed description of the invention] [Field of industrial application] This invention relates to an improvement of a floor outlet.

[Conventional technology]

Among conventional floor outlets, there is an outlet box with an internal outlet that can be freely inserted and removed from a hole in a box cover, with the outlet protruding from the floor only when in use and stored inside the floor when not in use.

[The problem that the idea aims to solve]

However, the above-mentioned conventional floor outlets have problems such as dust and moisture getting into the space between the hole provided in the box cover and the outlet box, causing the outlet box to become stuck or rusting. Ta. Furthermore, the above-mentioned conventional floor outlets have problems in that they lack safety, durability, and shock resistance against people and objects when the outlet part is exposed from the floor, and the outlet part is stored inside the floor. In the case of such a structure, it is easy for objects to pass through or get on top of the structure, so vertical loads are often applied to the structure, which sometimes causes damage.

Therefore, the floor outlet of this invention was created in order to solve the problems that the conventional floor outlets have.

[Means for solving the problems]

Therefore, in this invention, a ring 4 provided with a slide lever 3 is arranged around a circular hole 1 formed in a box cover 2, and the inner diameter of the ring 4 is contracted by operating the slide lever 3. It is designed to be brought into close contact with the side circumference of the outlet box 6. When the outlet section 5 is exposed from the floor, the shape of the exposed part of the outlet box 6 is made into a curved surface, and when the outlet section 5 is stored in the floor, the shape of the exposed part of the outlet box 6 is made into a gentle shape. It has a curved surface.

[Effect]

As a result of implementing the above-mentioned measures, this invented floor outlet has a seal between the circular hole 1 provided in the box cover 2 and the outlet box 6, and when the outlet part 5 is exposed from the floor, it can be used as an outlet for people and objects. Even if an impact is applied to the box 6, the impact will be weakened, and when the outlet section 5 is housed in the floor, it will be difficult for objects to pass over the floor outlet, and it will also be difficult for objects to ride on the floor outlet. Become.

〔Example〕

Hereinafter, the configuration of this invention will be explained based on the drawings shown as examples.

The floor outlet of this invention includes a box cover 2 with a circular hole 1, a ring 4 with a slide lever 3, an outlet box 6 with an outlet section 5 inside, a holding plate 7 for the outlet box 6, and a storage area for the outlet box 6. It consists of case 8.

In this embodiment, a ring groove 9 is provided around the circular hole 1 of the box cover 2. A part of the ring groove 9 is removed by a step portion 10.
is fitted into this step portion 10 from the inside of the circular hole 1, and the ring 4 is fitted into the ring groove 9.

The ring 4 is made of elastic synthetic resin or the like, and has a notch 1 at a position opposite to the slide lever 3.
1, and the slide lever 3 is connected to the notch 11.
By pushing in the direction, the ring 4 slides along the ring groove 9, and the notch 11 closes, thereby contracting the inner diameter of the ring 4. The inner diameter of the ring 4 can be contracted by any suitable structure other than sliding it along the ring groove 9 provided around the circular hole 1 of the box cover 2 as shown in this embodiment. Needless to say, it can also be implemented.

Furthermore, in order to lock the slide lever 3 in the stepped portion 10 of the box cover 2 and the slide lever 3 of the ring 4 in a state where it is pushed in toward the notch 11, one side is a convex portion and the other is a convex portion. An appropriate locking mechanism (not shown) such as a structure in which the two are fitted together as a recess is provided.

The outlet box 6 has a small circular part 12, which is formed by cutting the upper part of the sphere along a tangential plane, and has a gently curved surface, and a small circular part 13, which is formed by cutting the diagonally lower part of the sphere along a tangential plane, serves as an outlet part inside the outlet box 6. I made it so that the insertion side is 5. Further, support shafts 15, 15 are protruded from opposite positions on the outer surface of the outlet box 6, and the support shafts 15, 1
5 is supported by bearings 16, 16 of a holding plate 7, which will be described later, and by rotating the outlet box 6, the outlet part 5 can freely protrude and retract from the floor through the circular hole 1 of the box cover 2. ing. When the outlet part 5 is exposed from the floor, the spherical surface of the outlet box 6 is exposed, and when the outlet part 5 is stored in the floor, the gently curved surface of the outlet box 6 is exposed.

In this case, a torsion coil spring (not shown) or the like is interposed between the support shafts 15, 15 and the bearings 16, 16, so that the outlet box 6 rotates and the outlet part 5 is exposed from the floor. It is designed to stop at the position where it is placed or when it is stored in the floor.

The holding plate 7 is formed in a ring shape, and bearings 16, 1 of the support shafts 15, 15 of the outlet box 6 are provided at opposing positions on the inner circumference of the ring.
There are 6.

The storage case 8 is provided with a flange 18 at the upper end of the storage cylinder 17, and surrounds the outlet box 6 when the outlet section 5 is stored in the floor.

In addition, the cord (not shown) of the outlet section 5 is
Wiring is conducted through holes (not shown) provided at appropriate positions on the spherical surface of the outlet box 6.

[Effect of the invention]

The floor outlet of this invention is constructed as described above, and by operating the slide lever 3, the inner diameter of the ring 4 can be contracted and the ring 4 can be brought into close contact with the side circumference of the outlet box 6. , the space between the circular hole 1 provided in the box cover 2 and the outlet box 6 is sealed,
During this time, dust and moisture got into the outlet box 6 and the outlet box 6 no longer became stuck or rusted. Furthermore, in the floor outlet of this invention, when the outlet part 5 is exposed from the floor, the spherical surface of the outlet box 6 is exposed.
Even if a shock is applied to the outlet box 6 by a person or an object, the shock is weakened, making it extremely safe, durable, and shock resistant. Since the gently curved surface of the outlet box 6 is exposed, it is difficult for objects to pass over the floor outlet, and it is also difficult for objects to ride on the floor outlet, so there is less vertical load and there is a risk of damage. It has excellent effects such as:
