Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to the improvement of a sunken kotatsu, and particularly to the improvement of a stile placed around a floor opening formed by opening the flooring.

(Conventional technology) Traditionally, the horigotatsu was made in 1694.
As shown in Japanese Patent Publication No. 59-138853, a furnace box is installed in a floor opening provided by opening the subfloor, with the upper end of the peripheral edge being substantially flush with the surface of the subfloor; It is generally well known that a stile is placed on the subfloor surface around the periphery of the floor opening inside a floor finishing material that has an opening slightly larger than the floor opening, and a turret that is installed on top of the stile. There is.

By the way, the above-mentioned stile is used to make the height of the periphery of the floor opening flush with the floor finishing material, and its thickness needs to be set in accordance with the thickness of the floor finishing material. .

However, in the past, horigotatsu were expected to be installed only in Japanese-style rooms, so it was only necessary to use tatami mats as the floor finishing material. Therefore, since the range of the thickness of tatami is limited, there was no particular problem in setting the thickness of the stile.

(Problem that the invention aims to solve) However, in recent years, horigotatsu have been installed in Western-style rooms, and in these cases, the thickness of the floor covering material has varied widely from 10 to 60 mm. It will cross. For this reason, the following problems have arisen when setting the thickness of the frame.

In other words, if the thickness of the stile is set thin to match the thin floor covering material, if the floor covering material is thick,
It is necessary to install a height adjustment material under the stile to adjust the height of the stile, but in this case, when viewed from the floor opening side, there is a height difference between the stile and the furnace box. Because the adjustment material and gaps are visible, the appearance of the periphery of the floor opening becomes poor. Particularly when there are irregularities on the upper edge of the furnace box or when locking members are provided, these are also exposed to the outside, further deteriorating the appearance.
Furthermore, since the stile is thin, the area where the calf of the foot touches the stile becomes narrow during use, making it uncomfortable to sit on.

Furthermore, in cases where the turret is supported by a turret support material protruding from the inner surface of the stile, there is a problem in that the stile is thin, making it impossible to ensure sufficient support for the turret. There is also.

Conversely, if the thickness of the stile is set to be thicker to match the thick floor covering material, if the floor covering material is thin, the top surface of the subfloor where the stile will be placed will need to be lower than the top surface of other subfloors. However, there is a problem that the construction work becomes extremely complicated.

The present invention has been developed in view of these points, and its purpose is to improve the above-mentioned stile and add height adjustment material to the underside of the stile in accordance with the thickness of the floor finishing material. Even when installing the floor opening, it is possible to maintain a good appearance around the floor opening, as well as improve seating comfort.
The purpose is to provide a horigotatsu with excellent strength and workability.

(Means for Solving the Problems) In order to achieve the above object, the solution taken by the present invention is that the upper surface of the periphery is placed in the floor opening provided by opening the subfloor, so that the upper surface of the periphery is approximately flush with the above-mentioned subfloor surface. A hearth box that is installed together, a stile that is placed on the subfloor surface around the periphery of the floor opening inside the floor finishing material that has an opening one size larger than the floor opening, and a turret that is installed on top of the stile. The stile is formed to approximately the same height as the thickness of the tatami mat, and a height adjustment material for adjusting the height of the stile can be stored on the lower surface of the outer periphery. A cutout is provided so that the cross section L
It is formed in a letter shape, and its inner circumferential portion is arranged inward from the circumferential edge of the furnace box.

(Function) With the above configuration, the stile is formed at approximately the same height as the thickness of the tatami, so even when using the thickest tatami among commonly used floor finishing materials, the bottom surface of the stile No gap is formed between the upper end of the furnace box and the upper end of the furnace box.

In addition, the stile has an L-shaped cross section with a notch on the lower surface of its outer periphery that can accommodate a height adjustment material for adjusting the height of the stile.
Even if the height adjustment material is placed in the notch according to the thickness of the floor finishing material, the height adjustment material and the furnace box will be covered by the inner periphery of the stile, causing the stile and the furnace box to overlap. No height adjustment material or gaps will appear between the two.

In addition, the stile has an L-shaped cross section, and the height of the inner surface is as large as the thickness of a tatami mat. Since the inner peripheral part is arranged inward from the peripheral part of the furnace box,
At the bottom of the stile, the feet leave the hearth box.

Furthermore, the stile is formed into an L-shaped cross section, and the height of its inner surface is as large as the thickness of a tatami mat.
Sufficient support strength can be ensured even when supporting the turret by protruding the turret support material from the inner surface of the stile.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

Figure 1 shows the overall structure of a sunken kotatsu A according to an embodiment of the present invention installed in a Western-style room, where 1 is a subfloor, 2 is a relatively thin floor finishing material, and 3 is a subfloor 1. and a rectangular floor opening formed in the floor finishing material 2, and the floor opening 3 is set to be one size larger in the floor finishing material 2 portion than in the floor base 1 portion. Reference numeral 4 denotes an opening frame member disposed in contact with the lower surface of the floor base 1 and facing the floor opening 3.

Reference numeral 5 denotes a furnace box disposed below the floor opening 3, and the upper side wall of the furnace box 5 has its upper end surface flush with the upper surface of the floor base 1, and the opening frame members 4,... On the other hand, the bottom of the furnace box 5 is provided with a firing box containing a heating element (not shown). A stile 7 made of four frame members 6, 6, . . . assembled into a rectangular shape is disposed at the upper edge of the furnace box 5 (the edge of the floor opening 3). on the other hand,
A turret 12 consisting of a rectangular upper frame 10 and vertical members 11, 11, . . . is installed on the furnace box 5 while being supported by the stile 7.

The stile 7 has an outer surface of each frame material 6 in contact with the inner surface of the floor opening 3 of the floor finishing material 2, and an inner surface of each frame material 6 is closer to the floor opening 3 than the periphery of the floor opening 3 of the floor base 1. In addition, the thickness of each frame material 6 is thicker than the thickness of the floor finishing material 2,
As before, the thickness is set to be approximately the same as the thickness of tatami mats. As shown in detail in FIG. 2, each frame member 6 of the stile 7 is provided with a notch 13 on the lower surface of the outer circumference opposite to the upper edge of the furnace box 5, so that the frame member 6 has an L-shaped cross section. The notch 13 fits into the upper edge of the furnace box 5, and even though the thickness of the frame 7 is greater than the thickness of the floor finishing material 2,
The upper surface of the frame material 6 and the upper surface of the floor finishing material 2 are set to be flush with each other. Above hearth box 5, stile 7 and tower 1
2 constitutes the horigotatsu A of the present invention. In FIG. 2, reference numeral 14 denotes a locking member fixed to the upper peripheral edge of the furnace box 5.

Next, to explain the function and effect of the horigotatsu A, when the thickness of the floor finishing material 2 is thin as in the above embodiment, as shown in FIG. 1 and FIG. By fitting the notch 13 into the upper peripheral edge of the furnace box 5 and arranging the stile 7, the upper surface of the floor finishing material 2 and the upper surface of the stile 7 can be made flush.

On the other hand, if the floor finishing material 2 is thick, or if the horigotatsu A is installed in a Japanese-style room, for example, as shown in FIG. The stile 7 is interposed with a height adjusting material 15 having
By arranging this, the upper surface of the floor finishing material or the upper surface of the tatami mat 16 and the upper surface of the stile 7 can be made flush.

Moreover, in this case, the height adjusting member 15 and the upper end of the furnace box 5 are covered from the inside of the floor opening 3 by the inner circumference of the stile 7, and the height adjusting member 15 and the furnace box 5 are covered from the inside of the floor opening 3. The irregularities on the upper end surface, the locking member 14, etc. are not exposed to the outside, and no gap appears between the stile 7 and the furnace box 5. For this reason, floor finishing material 2
As in the case where the thickness is thin, the appearance can be maintained good, and the aesthetic appearance can be improved.

In addition, when using the horigotatsu A, the inner circumference of the stile 7 protrudes from the side wall of the hearth box 5, and the thickness of the inner periphery is approximately the same as the thickness of the tatami mat 16, so that the calves of the legs are attached to the stile 7. In addition to ensuring a wide area for contact with the stile 7, the feet are separated from the side wall of the furnace box 5 below the stile 7, making it extremely comfortable to sit on.

In addition, since the inner circumference of the stile 7 is thick, it is easy to cut and reinforce the turret support material when protruding from the inner surface of the stile 7, and the supporting force of the stile 12 is not sufficiently increased. can be secured.

Furthermore, the structure of the horigotatsu A is simply that a notch 13 is provided on the inner surface of the outer circumference of the stile 7 facing the upper edge of the hearth box 5, and the cross-sectional shape of the stile 7 is made into an L-shape. Moreover, there is no need to lower the opening frame material 4 below the level of the floor subfloor, which is very advantageous in terms of implementation.

In addition, since the inner peripheral part of the stile 7 is set to protrude from the side wall of the hearth box 5, the size of the turret 12 is slightly smaller than the size of the hearth box 5, so that the horigotatsu There is also an advantage that the tower 12 can be easily stored in the furnace box 5 when the tower A is not in use.

(Effects of the invention) As described above, according to the horigotatsu of the present invention, since the stile is formed at approximately the same height as the thickness of the tatami, even when tatami is used as a floor finishing material, the bottom surface of the stile and the hearth box are There is no gap formed between the upper surface of the periphery of the stile, and the lower surface of the outer periphery of the stile has a notch that can accommodate the height adjustment material and is formed into an L-shaped cross section, making it possible to finish the floor. Even if the height adjustment material is arranged according to the thickness of the material, the height adjustment material and the upper end of the furnace box will not be visible because they are covered by the inner circumference of the stile.
The appearance of the periphery of the floor opening can be maintained well, and the aesthetic appearance can be improved.

In addition, the height of the inner surface of the stile is made as large as the thickness of a tatami mat, and the inner periphery of the stile is placed inward from the periphery of the hearth box, so the area that touches the calves during use is wide. In addition to being able to secure the area, the feet are away from the furnace box below the stile, so
Improves sitting comfort.

Furthermore, since the height of the inner surface of the stile is formed to be as large as the thickness of a tatami mat, sufficient support strength can be ensured even when the stile support material is provided protruding from the inner surface of the stile to support the stile.

Furthermore, since the structure itself is simple, simply providing a notch on the lower surface of the outer periphery of the stile and making the cross-sectional shape of the stile L-shaped, there is no need to lower the periphery of the floor opening below the flooring. , which is very advantageous in implementation.
