The tower 27 can be prevented from moving horizontally. A closing plate 32 having a thickness H is detachably fitted on the upper part of the tower 27. A futon (not shown) is hung on the closing plate 32, and the top plate 33 is placed thereon. It has been done.

The closing plate 32 is fitted over the frame 16 or the box 8 with its peripheral edge fitted into the step 13 for the closing plate.

FIGS. 1 to 6 show a normal use state. FIG. 7 shows a case where the dugout 7 and the scaffold 27 are not used temporarily (for example, when the dugout 7 is used in a normal use state in the daytime and temporarily closed to lay a futon when going to sleep at night). The state of is shown. The protrusion 22 is removed from the recess 21 and the auxiliary saw 20 is removed,
The frame 16 is closed by the closing plate 32. FIG.
Indicates a state where the dug 7 and the scaffold 27 are not used for a long time. The auxiliary saw 20 and the frame 16 are removed, and the auxiliary saw 20 and the disassembled four frames 17 are stored in the box 8. Then, the box body 8 is closed by the closing plate 32, and the tatami 2 housed in a closet or the like is placed thereon.

[Second Embodiment of the Invention] (See FIGS. 9 to 11) In this description, the front means the front side of FIG. 9, the rear means the back side, and the left means FIG. The left side and the right side mean the right side in FIG.

At a required portion of the floor 42 of the Western room 41, a rectangular opening 6 having a stepped portion 43 around it is formed.
The horizontal part of the mounting bar 10 is attached to the step part 11 of the step drop part 43. A decorative edge 44 made of an extruded aluminum material or the like is attached to the upper peripheral edge of the opening 6.
The frame 16 is placed on a horizontal portion or the like of the mounting bar 10.

FIG. 9 shows a normal use state. FIG. 10 shows a state in which the dug 7 and the scaffold 27 are not used temporarily. The projection 22 is removed from the recess 21, the auxiliary saw 20 is removed, and the frame 16 is closed by the closing plate 32. The upper surface of the closing plate 32 has the same or substantially the same design as the upper surface of the floor 42. FIG. 11 shows a state in which the dug 7 and the scaffold 27 are not used for a long time. The auxiliary saw 20 and the frame 16 are removed, and the auxiliary saw 20 and the disassembled four frames 17 are stored in the box 8. Then, the box body 8 is closed by the closing plate 32, and the two crosspieces 48 housed in a closet or the like are placed on the front and rear portions of the closing plate 32 such that the longitudinal direction is directed to the left and right. On the crosspiece 48, the upper surface was housed in a closet or the like, and the upper surface was made the same or almost the same design as the upper surface of the floor 42.
A plurality of floor members 49 are placed so as to be aligned in the left-right direction and so as to be flush with or substantially flush with the upper surface of the floor 42. A decorative rim 50 made of an extruded aluminum material or the like is attached to a peripheral portion of each floor material 49. The opening 6 having no frame 16 is closed by the three floor members 49.

[0019]

[Modifications and the like] Modifications and the like will be described below. (1) FIG. 12 shows a modified example of the frame 17. In FIG. 12, the inner plate 24 does not have a portion protruding below the main body 23. (2) The kotatsu heater 14 may not be provided. In this case, since the futon is not required, the top plate 33 may be fixed to the tower 27. (3) The projection 22 may not be provided. (4) Thickness of closing plate 32, step portion 1 for closing plate of box 8
The height of 3 and the height of the step 13 for the closing plate of the frame 16 may be substantially equal. In short, when the closing plate 32 is put on the box body 8 or the frame 16, it is only necessary that there be no level difference that hinders walking or the like. (5) The size of the opening 6 is arbitrary. (6) The floor material 49 may be one sheet. By attaching short legs or the like to the lower part of the floor material 49,
Can be omitted. Further, the floor material 49 and the crosspiece 48 may be connected and fixed. The upper surface of the floor member 49 may not have the same or almost the same design as the upper surface of the floor 42.

[0020]

According to the present invention, the following effects can be obtained by the above-described configuration. According to the first aspect of the present invention, as described in the embodiment of the present invention, when dugout is not used temporarily,
Even if you do not use digging for a long time,
This is extremely convenient because it is possible to cope with the situation by effectively using one closing plate. Further, since the step portion for the closing plate of the frame is formed by attaching the inner plate so as to form the step portion for the closing plate with respect to the main body of the frame, Since the stepped portion for the plate is not formed by troublesome cutting of the work, the cost can be reduced and the yield of the raw material (raw material) can be improved. According to the second aspect of the present invention, when the closing plate is not used, the closing plate does not interfere. According to the invention of claim 3, as described in the embodiment of the invention, when the digging is not used temporarily, the frame can be easily closed by the closing plate,
When excavation is not used for a long period of time, the frame is removed so that the closing plate can be stored in the upper part of the box, and at the same time, the box is closed by the closing plate, so that dust and insects can enter the box. It can be prevented from entering. Further, since the stepped portion for the closing plate of the frame is formed by attaching the inner plate so as to form the stepped portion for the closing plate with respect to the main body of the frame, that is,
Since the stepped portion for the closing plate is not formed by troublesome cutting of the work, the cost can be reduced and the yield of the raw material (raw material) can be improved. According to the invention of claim 4, the rectangular opening without the frame is closed by the floor material having the same or almost the same design as the upper surface of the floor of the Western room, and the digging is performed while the design of the floor is unified. Can be concealed.
