Description

[Detailed description of the invention] TECHNICAL FIELD The present invention relates to digging.

The conventional horigotatsu shown in FIG. 1 can be stored in a stile 2 provided at the inner periphery of the opening of the hole 1 under the floor so that the tower legs 4 of the tower 3 are connected to the upper frame 5a of the tower as shown in the figure. It was attached inside the lower frame 5b.

As a result, the dimensions between the legs of the tower were narrow and the number of people who could use it was small.

The present invention has been made in view of the above-mentioned drawbacks, and its purpose is to allow the tower to be stored in a hole under the floor instead of the conventional structure, and to increase the dimension between the legs of the tower during use. We provide horigotatsu that can be used by many people.

The present invention will be explained below with reference to drawings of embodiments.

The floor 6 is open and a square box-shaped under-floor hole 1 is provided under the floor.

This under-floor hole 1 is formed by fitting a box-shaped main body A in advance, and a heater box γ is disposed below the bottom of the main body A. The heat from the heater 8 is transmitted into the main body A through an opening 9 at the bottom of the main body A.

A slatted heater lid 10 is fitted into the opening 9 of the main body A and covers the top surface of the heater box 1.

A frame-shaped stile 2 is provided at the inner periphery of the opening of the hole under the floor, that is, at the inner periphery of the opening in the floor 6, and a person sits on the floor 6 around this stile 2 and places his seat and feet in the hole under the floor. This puts it within 1.

The tower 3 is composed of an upper tower frame 5a in the form of a surrounding frame, a lower tower frame 5b of the same shape, and four tower legs 4, and a tower lid 11 is fitted into the tower upper frame 5a. .

The tower upper frame 5a has four portions 12 on the upper surface of the four corners, and shaft holes 13 are bored on the lower surface of the four corners so that the upper ends thereof open at the bottom surfaces of the recesses 12.

On the other hand, the tower lower frame 5b has a shaft hole 43a penetrating through the upper and lower surfaces thereof at a position corresponding to the shaft hole 13 of the tower upper frame 5a.

However, the shaft holes 13, 13a of the upper and lower frames 5a, 5b of the tower
Upper shaft 14a and lower shaft 14 provided at the upper and lower ends of the tower legs 4
The tower 3 is constructed by pivoting the shafts b such that they can rotate freely.

The tower legs 4 are made of, for example, metal plates or rods that are bent into a U-shape and have hair flocked on the surface. At the tip, the lower shafts 14b are integrally extended in the downward vertical direction, and by rotating the shafts 14a, 14b as centers, the vertical pieces 16 can be moved to the upper and lower frames 5a, S.
It is possible to go in and out of the room or outside.

18a. Reference numeral 18b denotes a removal stopper which is inserted into the upper shaft 14a and the lower shaft 14b, respectively.

In other words, the external dimensions of the tower upper frame 5a and the tower lower frame 5b are stile 2.
It is formed smaller than the internal dimensions so that it can be inserted into and out of the hole 1 under the floor through the opening of the stile 2, and when the horigotatsu is not in use, each tower leg 4 can be attached to the tower as shown in Figure 3. The entire tower 3 can be housed in the underfloor hole 1 by rotating it so that the upper and lower frames 5a and the vertical pieces 16 in the Sb opening are arranged.

In this case, the lower tower frame 5b is placed on the surface of the bottom surface of the main body A, which is on the road surface, and the upper surface of the heater lid 10, and the upper surface of the tower upper frame 5a and the lower surface of the stile 2 are approximately equal. If you set the length of the vertical piece 16 and press the button, the same floor material as that of the floor 6 can be used.If the floor piece 6a is fitted into the opening of the stile 2, the floor piece 6a/ /'i, it is placed and supported on the tower 3 and can constitute a part of the floor 6.

On the other hand, when using a horigotatsu, the tower legs 4 are
Rotate around 4a and 14b to remove the upper and lower horizontal pieces 15.
a, 15b are arranged in a position where they can be fitted into the fitting grooves 17 cut radially on the lower surface of the four corners of the tower upper frame 5a, and the vertical pieces 16 of each tower leg 4 are placed below the outside of the tower upper frame 5a. Dispense as shown in Figure 4.

As shown in Fig. 5, the lower horizontal piece 1 of each tower leg 4 is
5b is placed and engaged with the upper surface of the stile 2, the lower frame 5b of the tower is fitted into the opening of the stile 2, and the entire tower 3 is supported and arranged above the hole 1 under the floor.

At this time, as the tower upper frame 5a and tower lid 11 move downward, the upper shaft 14a moves above the recess 12 as shown in FIG. 6, and the upper horizontal piece 15a is inserted into the fitting groove 17 as shown in FIG. They fit together.

This prevents the tower legs from rotating 40 times and prevents the tower 3 from wobbling.

The load applied to the casing tower 3 is stopped by the lower horizontal piece 15b coming into contact with the upper surface of the stile 2.

In addition, as shown in FIG. 8, the lower shaft 14b is inserted into the shaft hole 19 drilled in the soil surface of the stile 2 without using the above-mentioned tower lower frame 5b.
may be inserted and detached.

As described above, the present invention forms a tower upper frame having an external dimension that allows entry and exit into the under-floor hole through an opening surrounded by a stile at the inner periphery of the opening of the under-floor hole, and is bent into a substantially U-shape. The upper shafts that protrude vertically from the tips of the water droplets of the four tower legs are attached to the four corners of the lower surface of the upper frame of the tower so that they can rotate freely in the horizontal direction, and the vertical pieces of each tower leg are connected to the tower. Since the upper frame can be freely moved in and out of the inner lower part and the outer lower part, the lower horizontal piece of the tower leg with the vertical piece protruding from the outer lower part of the upper frame is placed on the upper surface of the stile to raise the tower. The frame can be supported and arranged above the floor, and in this case, the dimension between the vertical pieces of the tower legs can be made larger than the width of the upper frame of the tower, that is, the width of the opening of the stile, which is different from the conventional method. Compared to a tower, more people can sit between the vertical legs, which has the effect of accommodating a large family.Moreover, the vertical legs of the tower are located below the inside of the upper frame of the tower. Since the tower upper frame and the tower legs can be stored in the hole under the floor, there is an effect that the tower can be stored in the hole under the floor as in the conventional case.

Claims (1)

[Claims] 1. A hole under the floor is created by opening the floor to allow people to put their feet under the floor, and a stile is placed around the inner circumference of the opening of the hole under the floor, so that it is possible to enter and exit the hole under the floor from the opening surrounded by the stile. A tower upper frame with external dimensions is formed, and upper shafts protruding vertically from the ends of four tower legs bent in a substantially U-shape are attached to the four corners of the lower surface of the tower upper frame, respectively.
