Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to a home kotatsu frame.

[Conventional technology and its problems]

In a home kotatsu frame that includes a substantially square top frame and four legs that are hung from the corners of the top frame,
Generally, each leg is attached to or detached from a corner of the upper frame by screwing screws provided on the upper end surface of the leg back and forth.

When such a conventional home kotatsu frame is packed, the upper frame and the legs are separated from each other. In other words, the top frame is kept in its original shape, and the legs are attached to the top frame for packaging. Therefore, it is quite bulky and difficult to transport from the manufacturer to the user.

Therefore, the purpose of the present invention is to provide a home kotatsu frame that can be disassembled and assembled, is easy to disassemble and assemble, and can be put together compactly when disassembled. .

[Means for solving problems]

The home kotatsu frame of the present invention has a substantially square top frame and four legs that are hung from the corners of the top frame. One side of the peripheral frame to be formed and a leg corresponding to one end of the one side are integrally connected to form four L-shaped members, and one L-shaped member is bent. and the other end of one side of another L-shaped member adjacent to the L-shaped member are successively connected by a removable connection mechanism consisting of an insertion protrusion and a hole. .

[Effect]

The home kotatsu frame according to the present invention has four L-shaped members, a hole is formed in the bent part of the L-shaped member, and an insertion protrusion is formed in the other end of one side of the L-shaped member. In the case where a hole is formed in the bent part of one L-shaped member, a hole is formed in the other end of one side of the other L-shaped member adjacent to the L-shaped member. By inserting the insertion protrusions, two adjacent circumferences and two legs of the kotatsu frame will be formed. Therefore, if all the insertion protrusions of the four L-shaped members are inserted into the holes, a substantially square peripheral frame and four legs hanging from the corners of the peripheral frame will be formed. You can assemble the provided frame. Then, by pulling out the insertion protrusion from the hole, the frame can be disassembled. Further, the insertion protrusion of the coupling mechanism is formed in the bent part of the L-shaped member, and the hole of the coupling mechanism is formed in the L-shaped member.
Even when the frame is formed at the other end of one side of the character-shaped member, the frame can be assembled and disassembled in the same manner.

When disassembled, the two L-shaped members are combined to form a substantially rectangular shape, and the two substantially rectangular members can be stacked and stored.

Insert the screw 24 into the through hole 21 and screw it into the screw hole 16 of the insertion protrusion 13 to remove the insertion protrusion 1.
3 and the hole 11 are fixed. Note that the small diameter portion of the through hole 21 may be a screw hole and the insertion protrusion 13 side may be a normal hole, or all the holes may be normal pilot holes and the screw 24 may be a self-tapping screw.

Next, the internal frame 6 is formed from a cylindrical body having a substantially rectangular cross section, and has construction sides 20, 20 connecting the two opposing sides 8, 8 of the peripheral frame 4, and the construction sides 20 and connecting sides 22, 22 that connect the two. Insertion protrusions 15, 15 are protruded from both end surfaces of the construction side portion 20. Furthermore, blind holes 27 are formed on the inner surface 26 of the side portion 8 at predetermined intervals. In other words, the insertion protrusion 15
The inner frame 6 is attached to the surrounding frame 4, and the inner frame 6 is attached to the surrounding frame 4.

However, the kotatsu frame configured as described above,
When assembled and disassembled freely and when divided, two L-shaped members 7, 7 are formed as shown in FIG.
A space formed by forming a pair of substantially rectangular combinations, stacking the paired members vertically, and combining the two L-shaped members 7, 7 into a substantially rectangular shape. In part 23,
It is stored with the inner frame 6 inside. Therefore, the length dimension B of this kotatsu frame in the stored state is
With one side of the top frame slightly longer than the length, the width dimension A can be made approximately the same as the length of the leg 3, and the conventional kotatsu frame While it was stored while maintaining the same length, it is now more compact. In addition, the thickness dimension including the heat generating part 5 and the internal frame 6 is
If the thickness dimension is approximately the same as that when the L-shaped members 7 are stacked one on top of the other, the heat-generating portion 5 will not protrude in the stored state, making it easier to pack.

Next, FIG. 4 shows another embodiment, in which the width of the upper surface 19 of one side 8 of the L-shaped member 7 is smaller than the width of the upper surface 25 of the leg portion 3, Further, the outer surface 28 of the leg portion 3 and the outer surface 29 of the one side portion 8 are formed in the same plane. In other words, the notch portion 30 is formed on the inner surface side of the side portion 8. And this L-shaped member 7
As in the above embodiment, the other end surface 1 of the side portion 8
4 is formed with an insertion protrusion 13, and a bent portion 9.

If connected by 8, the four circumferences of the kotatsu frame and the legs 3
4 can be formed.

However, the kotatsu frame configured as described above,
When disassembled, as shown in Figure 5, one L
The notch 30 of the L-shaped member 7 and the side 8 of the other L-shaped member 7 are fitted together to form a pair of substantially U-shaped combinations, and the pair is formed into a substantially U-shape. In addition to combining into a substantially rectangular shape, the space portion 23
It is stored inside the inner frame 6. Therefore, when this kotatsu frame is stored, the length dimension B is slightly longer than the length of one side of the top frame, and the width dimension A is approximately equal to the length of the leg part 3. The dimensions can be the same, making it more compact.

In addition, in the present invention, the insertion protrusion 13 is provided on the bending portion 9.
