Description

[Detailed explanation of the idea] This invention relates to the improvement of a sunken kotatsu.

The conventionally used horigotatsu cannot support the legs in a horizontally stretched state when lying down, resulting in an unnatural posture with the legs hanging down, resulting in inconveniences such as uncomfortable sleeping.

In order to eliminate this inconvenience, it is conceivable to install a footrest member on the top opening of the furnace box and support the feet in a horizontally extended state. There are problems such as the distance from the heater and the reduced heating effect.

Therefore, the present invention solves the above-mentioned drawbacks at once by configuring the receiving member for placing the feet so that it can be held in position at the bottom or top opening of the furnace box, and by integrally attaching the heater to the lower surface of the receiving member. It is intended to provide horigotatsu.

Hereinafter, one embodiment of the present invention will be described in detail based on the drawings.

In the horigotatsu 1 shown in Figs. 1 and 2, 2
is a furnace box with an open top surface, a heater box 3 having a flat rectangular storage chamber 3a is integrally formed in the center of the bottom portion 2a, and a stepped portion 2b is formed on the outer periphery of the top surface of the heater box 3. .

Reference numeral 4 designates a slatted support member for placing feet, and its peripheral edge 4a is fitted into the stepped portion 2b of the furnace box 2, so that it is flush with the bottom surface 2c of the furnace box 2.

Reference numeral 5 denotes a heater consisting of an infrared lamp, which is fixed to the upper surface of the rectangular substrate 6 and integrally connected to the lower surface of the receiving member 4 via support rods 7, 7, 7, 7 provided upright at the four corners of the rectangular substrate 6. are doing.

8 is a height adjustment mechanism for holding the receiving member 4 in position at the upper opening 2d of the furnace box 2, and the rectangular substrate 6
The four corners 6a, 6a, 6 of the rectangular board 6 can be removed by lifting the receiving member 4 and rotating it to the right or left when viewed from above.
A, 6a are made to correspond to the upper surface of the stepped portion 2b to form the storage chamber 3a.
It prevents the receiving member 4 from falling into the upper surface opening 2b.
It is formed to maintain its position.

9 is a tower, and a stile 10 on the top of the hearth box 2
It is supported by

When using the Horikotatsu configured as described above in a seated position, the heater 5 is stored in the storage chamber 3a of the heater box 3, and the receiving member 4 is placed in the stepped portion 2b of the furnace box 2, as shown in FIG. When inserted, the receiving member 4 is located at the bottom 2a of the furnace box 2, and the footwell becomes deeper, allowing a comfortable sitting position and allowing the user to relax comfortably without feeling numbness in his or her feet.

Next, when lying down with the upper body folded down, the support member 4
Lift it up and rotate it to the right or left when viewed from above to align the four corners 6a, 6a, 6a, 6a of the rectangular board 6 with the step part 2.
If it falls in a state corresponding to the top surface of b, the rectangular substrate 6
is supported by the stepped portion 2b, so the receiving member 4 is supported by the third
As shown in Fig. 4, it is held at a high position close to the opening 2d of the hearth box 2, and the legs do not droop and can be stretched out to the side, allowing a comfortable posture and a comfortable sleeping position without the legs becoming numb. Good.

Moreover, since the heater 5 moves upward together with the receiving member 4, it does not move away from the feet and the heating effect does not decrease, so there is no need to strengthen the heater to keep the foot warm.

Moreover, the upper surface of the heater box 3 is connected to a rectangular substrate 6.
The space inside the furnace box 2 is reduced, the heating efficiency is improved, and the heating cost can be greatly reduced.

In the above embodiment, the height adjustment mechanism of the receiving member is configured to engage or disengage the rectangular substrate 6 and the stepped portion 2b, but as shown in FIGS. 6 and 7, the heater box is shaped like a mortar. In the horigotatsu, the four corners 4 can be adjusted by lifting and rotating the receiving member 4.
b, 4b, 4b, 4b may be engaged with the upper surface of the lower frame 9a of the tower 9, so that the receiving member 4 can be held at the position shown by the imaginary line.

Further, the height adjustment mechanism is not limited to the one described above, but the height may be adjusted by suspending the receiving member 4 with a rope or chain, or another adjustment mechanism consisting of an elevator such as a jack can be used. Effects can be obtained.

Note that the receiving member is not limited to a slatted one, but may be a net plate-like one as long as it allows light and heat from the heater to pass through easily.
