Description

The present invention relates to an electric kotatsu that allows four legs provided at corners of a frame to be freely folded.

(B) Conventional technology Conventionally, an electric kotatsu in which the legs are folded is disclosed, for example, in Japanese Utility Model Publication No. 37-30149, but in such a configuration, the electric heater is largely lowered from the butt of the kotatsu main body. Since the protruding portion is protruded, there is a drawback that if the device is used as a low table in this state, the electric heater becomes an obstacle and the electric heater deforms on the floor surface.

(C) Problems to be Solved by the Invention Therefore, the present invention can be used as a low table in a state where the legs are folded, and also prevents breakage of the assemblage even when an overload is applied from above when using the low table. In addition, it is possible to prevent the electric heating unit from hitting the floor surface or a pillar or wall of a house beforehand, thereby preventing the electric heating unit from being deformed or damaged.

(D) Means for Solving the Problems A first configuration of the present invention is a frame combined in a rectangular shape, a plurality of joints combined in a well shape in the internal space of the frame, and An electric heating unit which is mounted between the lozenges so as to be substantially flush with the lower end surface of the lozenge so that its corners are located on a diagonal of the frame, and the frame provided at the corners of the frame. And four legs that can be folded in the diagonal direction, and a part of the legs is configured to be freely foldable so as to be horizontal. It is configured to be in contact with and cover the lower surface of the electric heating unit.

According to a second configuration of the present invention, the frame is combined in a rectangular shape with four long plates via a mounting bracket, and the legs are fixed to the mounting bracket and the fixed legs. The fixed legs are interposed between the ends of the frame, and constitute the corners of the frame.

(E) Operation With this configuration, even if the leg is folded and the kotatsu is placed on the floor surface to be used as a low table, the leg abuts on the lower surface portion of the stay and the electric heating unit can be pushed in. Therefore, deformation of the electric heating unit can be prevented. In addition, since the legs are folded in the diagonal direction of the frame, even when a heavy load is applied from the top of the frame when using it as a folded low table, the legs can be spread over a wide area below the frame. Can be prevented from being broken. In particular, when the leg is moved after folding, a part of the leg covers the electric heating unit, so that even if the kotatsu body hits a pillar or a wall of the house, the electric heating unit is not deformed or damaged.

(F) Example (1) shows a kotatsu main body, and a frame (3) in which four long plates are combined in a frame via a mounting bracket (2) having a substantially U-shaped cross section. In the internal space of the frame (3), four ridges (4) combined in a well shape and these ridges (4) ...
An electric heating unit (5) for forcedly generating hot air in a substantially square shape disposed in the space defined by the above, and four legs (6) provided at the corners of the frame (3), etc. It is formed with.

The electric heating unit (5) has a thin shell composed of a decorative plate (7) and a protective guard (8), and a flat air guide plate (9) and a pair of air guide plates inside these internal spaces. And a fan (12) rotatably driven by a motor supported by a support plate (11). (13) is a hot air control knob for controlling the power supply to the heaters (10) and (10), and (14) is a power cord. The electric heating unit (5) is housed and arranged in a space formed by a plurality of rods (4)... And the lowermost end of the electric heating unit (5) is as shown in FIG. The lower end surface of the slab is substantially flush with or slightly recessed. The electric heating unit (5) is fixed from the side surfaces of the housing (4) by screws (15) (15).

The leg (6) is connected to the mounting bracket (2) with a bolt (20).
And a folding leg (6b) that can be folded and operated by a pivoting mechanism (not shown) with respect to the fixed leg (6a). ing. The fixing leg (6a) is interposed between the ends of the plate of the frame (3) and is fixed to the mounting bracket (2), and as shown in FIG. 1 and FIG. It constitutes a corner. The folding legs (6
The length b) is set to cover the lower surface of the electric heating unit (5) as shown in FIG. Moreover, the folding legs (6b) are 2
The abutments (4) and (4) of the book are configured to contact the lower surface of the mating portion (T).

Therefore, since the electric heating unit (5) is configured so as to be recessed or substantially flush with the lower end surface of the housing (4), the folding leg (6b) of the leg (6) is connected to the electric heating unit (5). The lower surface of (4) can be folded so as not to be disturbed by 5), and can be folded so as to abut the mating portion (T). As a result, the lower surface of the electric heating unit (5) can be covered with the folding legs (6b). Thus, as shown in FIG. 3, the leg body (6) is folded and the kotatsu body (1) is leaned against a wall, or when being carried, the kotatsu body (1) is attached to household electric appliances and furniture in the room.
, The electric heating unit (5) is protected by the folding leg (6b) of the leg (6).

And the folding leg (6b) is simply an electric heating unit (5)
In addition to covering the lower surface of the electric heating unit (5), the folding leg (6b) does not directly deform the protective guard (8) of the electric heating unit (5) by pressing it from below. ) To be in contact with the lower surface.

Moreover, the folding leg (6b) is the joint (T) of the ridge (4) ...
4 or only slightly touch the lower surface of the electric heating unit (5). Therefore, when the leg (6) is folded and used as a low table as shown in FIG. Even if external force due to household electrical appliances or furniture is applied to the folding leg (6b) of the leg (6) from above, most of the external force is absorbed and dispersed in the joint (T) of the inn (4). Since no external force is applied to a single lodge (4), partial deformation or breakage of the lodge (4) is prevented, and deformation of the entire kotatsu body (1) is prevented. It is.

It is sufficient that the folding leg (6b) slightly covers the lower surface of the electric heating unit (5), and it is particularly preferable that the folding leg (6b) is folded diagonally from the corner of the electric heating unit (5). Naturally, the longer the folding legs (6b), the better.

(G) Effects of the Invention Since the present invention has such a configuration, even when the legs are folded and used as a low table, the folded legs directly press the lower surface of the electric heating unit strongly. Instead, the electric heating unit is prevented from being deformed or damaged on the mounting surface such as the folded legs or the floor surface because the electric heating unit is in contact with the lower surface portion of the housing.

And since the leg is provided so as to be foldable in the diagonal direction of the frame, the leg is positioned below the ridge inside the frame at the time of folding, and even if a large excess is applied to the center of the upper surface of the frame, the leg may be folded. The body is protected by the body and does not break.

In particular, when the leg is moved after folding, part of the leg covers the electric heating unit, so even if the leg acts as a guard of the electric heating unit and the kotatsu body hits the pillar or wall of the house, the electric heating unit will not No deformation or breakage.

In addition, since the fixing legs are provided on the end surface of the frame, even if a horizontal force is applied to the frame, the fixing legs serve as a cushioning material to prevent twisting and to prevent twisting. The frame is maintained in a stable state regardless of whether the leg is used as a folded low table or as a standing kotatsu.
