Description

[Detailed description of the invention] Industrial applications The present invention relates to a horigotatsu.

Conventional structure and problems The horizontal cross section of the hori kotatsu's hori frame is polygonal, often rectangular, so when you put your foot in the corner, it feels like you're being wedged between the two walls.
It lacked comfort.

OBJECT OF THE INVENTION The present invention therefore improves comfort.

Structure of the Invention In order to achieve the above object, the present invention includes a moat frame having a polygonal horizontal cross section, a heating element unit that heats the inside of the moat frame, and a moat frame provided on each corner of the moat frame. It is equipped with a corner spacer and a stile provided on the upper part of the moat frame on both sides of the corner spacer, the upper surface of the corner spacer is covered with a cover made of synthetic resin, and the inner side of the moat frame of this cover is lowered into the moat frame. This descending portion is curved toward the outside of the trench frame in the horizontal direction.

DESCRIPTION OF THE EMBODIMENTS In FIG. 1, reference numeral 1 indicates a bottomed moat frame 1 made of wood, and the horizontal cross-sectional shape of the moat frame 1 is approximately square. Further, as shown in FIGS. 2 and 3, the peripheral edge of the trench frame 1 is fixed to the root 4 of the floor 3 using a metal fixture 2 with an L-shaped cross section and screws 2a. .

Note that the left and right clearance between the moat frame 1 and the neta 4 is set at 10 to 30 mm, making it easy to insert the moat frame 1.

Furthermore, a wooden stile 5 is provided at the upper end of the moat frame 1 corresponding to each side, and wooden corner spacers 6 are provided between each side. In other words, the stile 5 is provided on both sides of the corner spacer 6 at the four corners. The stile 5 and the corner spacer 6 are assembled by fitting the concave portion 5a of the stile 5 and the convex portion 6a of the corner spacer 6.

A cover 4 made of synthetic resin is attached to the upper surface of each corner spacer 6, and the moat frame 1 side of this cover 7 forms a wall surface 7a that descends into the moat frame 1, and this wall surface 7a extends in the horizontal direction. As shown in Figure 3, the moat frame 1 is curved outward at the base of the moat frame 1 to prevent discomfort when stepping in and out of the moat frame 1, and its lower end is lowered to the bottom of the moat frame 1 as shown in Figure 2. There is.

On the other hand, on the center of the bottom surface of the trench frame 1, a pillar 8 made of wood and having a prismatic shape is erected on the leg 9 of FIG. 1 as shown in FIGS. 4 and 5. The leg 9 is formed by combining wooden pieces into a square shape, and its outer diameter is smaller than that of the support column 8.
In this state, the cutout opening edge 10a of the carpet 10 on the bottom surface of the trench frame 1 comes into direct contact with the outer periphery of the leg 9 as shown in FIG. It is in a covered state.

Next, a heating element unit 11 shown in FIG. 1 is housed inside the support column 8 as shown in FIG.
Next, the structure of this heating element unit 11 will be explained.
The heating element unit 11 has a top plate 13 and a bottom plate 14 on the upper and lower ends of four pillars 12 arranged in a rectangular shape, and a heat shielding reflector 15 is provided horizontally slightly below the middle part to form an exterior body. ing. And top plate 13
An infrared heater 17 with a reflector 16 and a Shirotsuko fan 18 are provided between the heat shield reflector 15 and the heat shield reflector 15, and a motor 19 for driving the Shirotsuko fan 18 is provided between the heat shield reflector 15 and the bottom plate 14. There is.

In addition, openings 8a are provided on each of the four outer peripheral surfaces of the support column 8, which correspond approximately to the space between the top plate 13 and the heat shielding reflector plate 15.
0 are fitted respectively.

A rectangular wooden top plate holder 21 is fixed to the upper end of the column 8, and the top plate holder 21, the heating element unit 8, and the moat frame 1 are an example of a columnar first fixture. They are integrally fixed by a bolt 22 used as a bolt 22 and a nut 23 with a rotation stopper used as an example of a second fixture to be coupled with the bolt 22.

In other words, four holes 21a and 9a are provided in the top plate support 21 and legs 9, holes 21a in the lower end of each bolt 22 with a length of 60 cm, holes 24a in the wooden guide 24 at the upper part of the column 8, and holes 24a in each column 12. The nut 2
The three are connected, and as a result, the three are firmly fixed. In this state, bolt 2
The head 22a of the bolt 22 sinks into the recess 21a of the top plate holder 21 as shown in FIG.
3 is hermetically housed in a recess 25a formed in a wooden reinforcing body 25 provided on the bottom surface of the trench frame 1. In other words, since the area below the trench frame 1 is under the floor, the humidity is high, and if the joint between the metal bolt 22 and the metal nut 23 is left exposed here, it will oxidize and become difficult to release. This joint is hermetically housed in the recess 21b and shielded from moisture.

Further, by coupling the bolt 22 and nut 23, a wooden accessory case 26 is also integrated into the upper part of the support column 8.

In other words, there is a concave notch 8 in one opposing part of the upper part of the support column 8.
b, and an accessory case 26 opposite to this notch 8b and having a concave cross-section and a larger opening than this notch is provided in the support 8, and in this state, the accessory case 26
The lower part of 6 is supported by the receiver 27, the left and right sides are held inside the guide 24, and the upper part is pressed downward by the top plate holder 21, thus making them integrated.

Next, the lower part of a rubber non-slip 28 is fitted into the four corner recesses (not shown) on the outer circumference of the top plate holder 21, and the upper surface of this non-slip 28 is used as a kotatsu in winter, as shown in Fig. 5. A wooden top plate 30 comes into direct contact with the lower surface of the button 29 except in winter. As shown in FIG. 4, the outer diameter of the top plate 30 is larger than the outer diameter of the top plate holder 21, and the peripheral edge curves downward to form an edge 30a. And this edge 30a
The top plate support 21 is located in the inner space, and the inner upper part a of the edge 30a hangs down, then slopes outward and widens b, and then horizontally spreads outward c. The dimension A of the edge 30a is 39 mm, the dimension B is 22 mm, the B dimension of the top plate holder 21 is 23.5 mm, and the protrusion dimension of the anti-slip 28 from the top plate holder 21 is 5 mm. The reason why the slope b is provided on the inside of the edge 30a of the top plate 30 is that when the kotatsu button 29 is used as shown in FIG. This is to prevent the edge 30a of the top plate 30 from slipping down on the top plate holder 21. In other words, the button 29 that would fall if there was no slope b
Due to the thickness of the top plate 30, the lower end of the edge 30a of the top plate 30 is located above the top plate holder 21, causing the top plate 30 to slide down.

In addition, 31 in FIG. 1 is a spacer when the top plate holder 21 is installed slightly above, and as can be seen from FIG.
2 is provided with a hole 31a through which the top plate holder 21 passes, and a protrusion 31b that projects into a recess (not shown) on the lower surface of the top plate support 21. FIG. 8 shows a configuration in which two spacers 31 are provided, and the protrusion 31b of the lower spacer 31 is designed to protrude into a hole (not shown) in the upper spacer 31.

Again, 32 in FIG. 1 is a lead wire that supplies power to the infrared heater 17 and motor 19, and this lead wire 32 penetrates the bottom of the moat frame 1 and then proceeds outside the moat frame 1 (not shown). passes through the floor 3 and is guided to a controller 34 on a wall 33 of the room.

The controller 34 controls the supply of electricity to the infrared heater 17, and has a power switch 35 and a pilot lamp 36 on its surface, and contains electronic parts for controlling the supply of electricity, such as a thyristor, for controlling the supply of electricity.

A thermostat (not shown) for detecting the temperature inside the trench frame 1 and a variable resistance knob 37 for setting the temperature are attached to the column 8, and these thermostats, knobs 37, and controller 34 are connected to each other. The electronic components for controlling current flow are the control components.

In the above configuration, when the kotatsu button 29 and the top plate 30 are set on the top plate holder 21 as shown in FIG. will be held.

Then, the infrared heater 17 becomes red hot, and the infrared rays are emitted obliquely from the gaps between the louvers 20 toward the feet.

When the motor 19 drives the Shirotsuko fan 18, the air in the trench frame 1 is sucked upward into the column 8 from the top of the louver 20 due to the inclination of the louver 20, and is converted into warm air by the infrared heater 17. After that, it is blown out from the center of the Shirotsuko fan 18 to the outer periphery, and then blown out from the gap at the bottom of the louver 20 and downward toward the feet due to the inclination of the louver 20.

In other words, the feet are effectively heated by infrared rays and warm air.

Next, the characteristic parts of this embodiment will be explained.

In other words, in this embodiment, the curved wall surface 7a is provided at the corner of the moat frame 1, so even if you put your foot in from this corner, you will not feel that your foot is pinched from both sides, making it comfortable to use. can be done.

Effects of the Invention The present invention provides a moat frame whose horizontal cross section is polygonal;
a heating element unit that heats the inside of the moat frame; a corner spacer provided on each corner of the moat frame;
This corner spacer is provided with a stile provided on the upper part of the moat frame on both sides, and a cover made of synthetic resin is placed on the upper surface of the corner spacer, and the inner side of the moat frame of this cover is lowered into this moat frame, and this lowering Since the part is curved horizontally toward the outside of the moat frame, even if you put your feet in from the corner part of the moat frame, your feet will not feel like they are being pinched from both sides, making it comfortable.

Also, as a result of this, many people can use it because they can put their feet in from the corner.
