DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a frame device with a top plate on which a top plate is placed on the upper surface of the frame.

[0002]

2. Description of the Related Art An electric kotatsu is a typical one that is used by placing a top plate on the upper surface of a frame.

[0003] This is because electric kotatsu is originally used for warming in winter, but due to changes in lifestyle, in spring, summer and autumn, a top plate is placed directly on the top of the frame. This is because they are often used as tables and sitting tables. (Japanese Utility Model Application Laid-Open No. 60-140821) The electric kotatsu used throughout the year is to be handled as easily as possible, for example, when cleaning a room or when putting in and out of a room every few weeks. The legs attached to the frame can be folded freely. (Japanese Patent Laid-Open No. 5-
No. 215344)

[0004]

However, when the frame and the top plate are not used, they are stacked and pushed in or leaned against one corner of the room. However, when the frame and the top plate are overlapped, the overall thickness becomes considerably thick. When a large storage space was required and the wall was leaned against the wall of the room, the top plate slipped off the frame and was dangerous.

According to the present invention, when the frame is not used, the total thickness of the frame and the top plate when they are stacked is reduced to reduce the storage space and prevent the top plate from moving.

[0006]

According to the present invention, there is provided a frame having a plurality of foldable legs mounted thereon, and a synthetic resin top plate mounted on an upper surface of the frame. A plurality of recesses for receiving a part of the legs in a folded state are integrally formed on one surface.

The recess is provided with an enclosing wall surrounding the leg in a folded state.

The frame is formed in a square shape, a heating device is attached to the center of the frame, and the legs are folded in a diagonal direction of the frame. The top plate is formed in a square shape and the concave portion is formed. The place is provided in the diagonal direction of the top plate corresponding to the folding direction of the leg, and each of the recesses is connected to each other, and the opening provided at the end portion is provided outside the top plate. It is the one facing the edge.

Further, an outlet of a commercial power supply is provided on an outer edge of the top plate.

Next, the state of use will be described. Legs (2)
(2) FIG. 3 shows a usage pattern in which (2) (2) is raised and placed on the upper surface of the top plate (5) on the upper surface of the frame (1).
The power plug of another electric appliance such as a personal computer, a word processor, a fluorescent lamp, etc. mounted on the top of the top plate (5) is connected to the outlet (8) as necessary to supply AC power. .

When used as an electric kotatsu in winter,
A quilt (not shown) is hung on the upper surface of the frame (1), the top plate (5) is placed on the upper surface, and the plug of the power cord (4) of the heater unit (3) is connected to an outlet ( 8).

FIG. 1 shows a case where the inside of a room is cleaned or moved to another room with the frame (1) and the top plate (5), or stored in a closet or a storeroom due to off season. After folding all legs (2), (2), (2), and (2) in advance as described above, the recesses (7), (7) of the top plate (5)
(7) The legs (2), (2), (2), and (2) are housed in (7).

In this state, most of the legs (2), (2), (2) and (2) projecting from the lower surface of the frame (1) are mostly recessed (7) (7) (7) (7). ) And frame (1)
And the top plate (5) are superimposed, so that even if it is placed leaning on the wall in the room, the surrounding walls (6), (6) ... are legs (2) (2) (2) (2) The top plate (5) does not slide down from the frame (1) on the side wall of (1).

(10) and the recesses (7), (7), (7), (7), are released to the atmosphere from the openings (11), (11), (11), (11), and the dew condensation on the lower surface of the top plate (5) is reduced. To prevent.

[0021]

As described above, according to the present invention, a recess for accommodating the folded leg attached to the frame is integrally formed on one surface (upper surface) of the top plate. When cleaning the unit, storing it in a closet or a storage room, even if it is leaned against a wall, the top plate does not separate from the frame and can be stably held without slipping down, and the overall thickness is slightly reduced, so it is a little narrow space Can be stored.

Further, since the recess is provided with an enclosing wall surrounding the periphery of the leg, the enclosing wall is provided with a reinforcing action for maintaining the shape of the recess and the mutual contact between the top plate and the frame in contact with the leg. Rattling can be prevented.

Furthermore, since the plurality of recesses are connected to each other and the opening at the end faces the outer edge of the top plate, high-temperature air on the lower surface of the top plate due to heating by the heating device is passed through the recesses. To release the air from the opening to the atmosphere to prevent the top plate from being thermally deformed and also to prevent moisture from being generated on the futon, for example, hung on the upper surface of the frame.

Since an outlet of a commercial power supply is provided on the outer edge of the top plate, it is possible to easily secure a space for wiring inside the top plate in addition to insulating the top plate with a synthetic resin material. At the same time, it is possible to supply power to other appliances from the outlet, and it is possible to expand applications by using a combination of the frame and the top plate.
