Description

[Detailed description of the invention] [Technical field] This invention relates to a sunken kotatsu whose main body is installed under the floor.

[Background technology]

As shown in FIG. 7, the conventional horigotatsu has a main body 30 installed under the floor and a heater box 31 at the bottom, and an inner stile 33 protruding from an outer stile 32 at the upper edge of the main body 30. A low table part 3 consisting of legs 34 and a top plate 35 attached to this inner stile 33
It consists of 6.

In such a conventional horigotatsu, the low table part 36
Since the inner stile 33 is required in addition to the outer stile 32 to support the legs of the foot, there is a problem in that the amount of material used increases and the cost increases.

[Purpose of invention]

The purpose of this invention is to provide a sunken kotatsu that can stably support the legs of a low table without using a conventional inner stile.

[Disclosure of invention]

The horigotatsu of this invention consists of a stile that is installed on the upper edge of the main body installed under the floor and has a framework to form an opening in the floor, and a stile that is attached to the inner surface of the stile at the corner of the floor opening. A leg support having a receiver having a first screw insertion hole in a receiving surface protruding from the inner surface, and a second screw insertion hole arranged on the receiving surface of the receiver and communicating with the first screw insertion hole. a base, a leg whose lower end surface is placed on the leg support base to support a low table top plate, a female threaded portion is formed on the lower end surface, and the area of the lower end surface is smaller than the area of the leg support base; A male thread is screwed into the female threaded portion of the leg from the lower surface of the receiver through the first and second screw insertion holes to fix the leg to the leg support.

In this way, according to this invention, a receiver is attached to the inner corner of a floor opening formed by framing a conventional outside stile, and a leg support is placed on the receiver for a low table. Since the legs are placed on top, there is no need for an inner stile like in the past, and the amount of material used can be reduced. Further, since the legs are not supported directly by the support but via a leg support having a larger surface area than the legs, the legs do not feel like they are floating in the air and a high sense of stability can be imparted.

Embodiment An embodiment of this invention will be described based on FIGS. 1 to 5. That is, as shown in Fig. 1, this horigotatsu has a stile 4 that is installed at the upper edge of the main body 1 installed under the floor and has an opening 3 formed in the floor 2...a holder attached to the inner surface. The lower end surface of the leg 7 is placed and fixed on the leg support 6 via the leg support 6.
The top plate 8 for a low table is supported by.

The leg support 6 is arranged at the inner corner A of the floor opening 3, as shown in FIG. For more details,
As shown in FIG. 3, a receiver 5 is attached to the inner surface of the stile 4 on one side of the corner A of the floor opening 3, and a leg support 6 and a leg 7 are sequentially placed on the receiver 5. do. The receiver 5 has a first screw insertion hole 9 formed in a receiving portion 5a that projects from the inner surface of the stile 4, and the leg support 6 has a second screw that communicates with the first screw insertion hole 9. An insertion hole 10 is formed. Further, a female threaded portion 11 is formed in the lower end surface of the leg 7 by embedding a blind nut, and the first and second screw insertion holes 9,
The leg 7 is screwed together with the male screw 12 inserted through the leg 10.
is fixed on the leg support 6. FIG. 4 shows the fixed state of the legs 7. In this way, the legs 7 that support the low table top 8 are not directly received by the fixtures 5, but are fixed via the leg supports 6, so that the legs 7 do not feel like they are floating in the air. Further, since the area of the leg support 6 is larger than the area of the lower end surface of the leg 7, an even higher sense of stability can be provided. Furthermore, since the conventional inner stile is no longer necessary, the amount of material used can be reduced and costs can be reduced.

The leg support stand 6 and the stile 4 have the same height, and are constructed so that the upper surface of the leg support stand 6 and the upper surface of the stile 4 are on the same plane, as shown in FIG.

Another embodiment of this invention will be described based on FIG. That is, as shown in FIG. 6, this sunken kotatsu is such that the upper surface of the leg support 6' is located lower than the upper surface of the stile 4', and a step B is formed between them.

Therefore, in this embodiment, in addition to the effects of the previous embodiment, when the low table is placed on the leg support 6', the lower end of the leg 7 is positioned on the inner surface of the stile 4', so the leg 7' This has the effect of making positioning easier. The rest is the same as the previous embodiment.

[Effect of idea]

According to this idea, a receiver is attached to the inner corner of a floor opening formed by framing a conventional outside stile, and legs for a low table are placed on the receiver via a leg support. This eliminates the need for the conventional inner stile, reduces the amount of materials used, and reduces costs. Additionally, the legs are placed on a leg support that has a larger surface area than the legs, rather than being supported only by a support, so the legs do not feel like they are floating in the air, giving a high sense of stability. .
