Description

[Detailed Description of the Invention] The present invention relates to a table that can be stored under the floor and can also be used as a kotatsu table in winter.

Tables are generally installed in living rooms, dining rooms, etc. and are used for multiple purposes, such as a place for people to eat, hang out, or work, but they are not always necessary and often get in the way. Often. For this reason, when it is not needed, a part of it can be folded down to make it smaller.
As seen in Publication No. 73880, hollow tubes were erected at the four corners of a buried box with a bottom, and the four legs attached to the four corners of the table were inserted into these hollow tubes, and the entire kotatsu was placed under the floor. A device that can be stored has been developed. However, the former type of foldable table is not only extremely inconvenient, but also laborious as there are few places to put it away these days, where many homes are cramped. On the other hand, the latter under-floor storage table was very convenient because it allowed the table to be put away without constricting the living space, but the conventional one had hollow tubes installed in the four corners. Therefore, the hollow tube gets in the way when sitting in a corner, and the actual volume inside the vertical hole is reduced.
There was a problem that the number of seats was reduced, as well as that the storage work under the floor and the assembly work were troublesome. In addition, since the four legs are inserted into hollow tubes at the four corners, it is necessary to hold the table horizontally when raising and lowering the table plate, or the direction in which the legs will slide and the hollow tube The direction of the hollow is different from that of
There is a problem in that it takes time to assemble the table when the legs do not slide smoothly and the table is heavy.

On the other hand, horigotatsu are essential especially in winter, but they are unnecessary outside of winter and must be put away in an appropriate place. However, the conventional method is extremely inconvenient because it requires removing the tower, arranging it in an appropriate location, and then covering the floor with boards or the like, and the tidying up work is troublesome.

The present invention was developed in view of the above circumstances, and consists of a vertical hole provided in the floor with a post erected approximately in the center, and a retractable leg with a table board attached to the top end of the post. However, the table plate is positioned above the vertical hole with the telescopic legs fixed to the above-mentioned supports, and the table plate is formed so as to close the opening of the vertical hole when the retractable legs are retracted. It can be easily used as a horigotatsu, and there is no obstruction when sitting in the corner.Furthermore, the volume inside the vertical hole can be effectively used, making full use of the number of seats, and making it possible to use the table board. It is an object of the present invention to provide an under-floor storage table that can be put into use or storage by simply raising and lowering it, and can be stored and assembled under the floor extremely easily.

The present invention will be explained in detail below based on the drawings.
The figure shows an embodiment of the present invention, in which one support 2 is erected inside a vertical hole 1 provided in the floor F.
This support column 2 is attached with telescopic legs 3 to which a table plate 4 is attached at the upper end.

The vertical hole 1 is dug into the floor F so as to use the surrounding floor surface as a seat, and is composed of a furnace box 10 and a stile 11 attached to the upper end of the furnace box 10. Here, the furnace box 10 is formed from a member having a required heat retention property, and a locking portion 12 is provided on the inner surface near the bottom surface of the furnace box 10.
A fitting portion 18 is provided inside the stile 11 . Furthermore, in the locking portion 12 of the furnace box 10,
A support frame 14, which has been appropriately reinforced, is removably attached by connecting means such as screws.

The support column 2 is vertically provided approximately at the center of the upper surface of the support frame 14, and is configured to fit within the vertical hole 1 together with the support frame 14. Further, on the upper surface of the support frame 14, a gridiron 15 is laid over almost the entire surface surrounding the support column 2, so that feet can be placed thereon.

Next, the telescopic leg 3 has two upper and lower links 16.
It consists of a pair of left and right bending members 17, in which a and 16b are bendably connected by a hinge 28c. Said telescopic legs 3
The lower end of is a corner formed by the support frame 14 and the support column 2, and is located on the upper surface of the support frame 14.
It is rotatably attached via a hinge 28b. Further, the upper end of the telescopic leg 3 is rotatably attached to the lower surface of the table board 4 via a hinge 28a. Here, the telescopic leg 3 is removably fixed by a connecting means such as a screw 18 at a position where it abuts the outer surface of the support column 2 and is perpendicular to it in the extended state. In this extended state, the table plate 4 is positioned above the vertical hole 1 and is in use. On the other hand, when the telescopic legs 3 are retracted, the table plate 4 is fitted into the fitting portion 18 and stored in the vertical hole 1 with its upper surface substantially aligned with the surrounding floor surface.

Next, the operation of the embodiment will be explained. FIG. 1 shows the machine in use, with the telescoping legs 3 extended and the table board 4 positioned above the vertical hole 1. When using this, sit on the floor around the vertical hole 1 and place your feet on the drainboard 15. When using this as a kotatsu, a heater 25 and a heat sink 26 are provided in the furnace box 10, and a kotatsu cover 27 is placed over the table board 4. On the other hand, when storing under the floor, the screws 18 are removed, the telescopic legs 3 are removed from the support columns 2, and the table board 4 is retracted, and the table board 4 is fitted into the fitting part 13, and the table board 4 is stored in the state shown in FIG. 2. In this case, since the telescoping legs 3 are formed of bendable members 17, the telescoping legs 3 can be
moves up and down smoothly. Therefore, even if it is a heavy table board, it does not take much time. In addition, here, table board 4 is adjusted according to the surrounding situation.
You may also place a carpet, etc. on top.

By the way, in the above embodiment, the table plate 4
is formed from a simple plate material, but as shown in FIG. It is also possible to configure the tatami mat 23 with a top plate 24 that is placed on top of the tatami mat 23. In this way, if the top plate 24 is removed when the tatami mat 23 is stored under the floor, the tatami mat 23 can be seen on the top surface. It is possible to provide a table with an extremely good appearance in terms of design. Furthermore, when using it as a regular table, the slatted 15
Instead of this, you may place a board or the like on which you can place the feet.

As mentioned above, in this invention, the extendable legs are attached along the outer surface of the support column installed approximately in the center of the support frame installed in the vertical hole, so that the table board can be raised and lowered, so that it can be easily used when sitting in a corner. There are no obstacles in the way, and a sufficient number of seats can be secured, and even with the installation of pillars, the space inside the shaft can be fully utilized. In addition, the telescoping legs are made of a bending member that connects two upper and lower links, and a table board is attached to the top end of the telescoping legs to allow the table board to move up and down, making it possible to move smoothly even with heavy table boards. It can be raised and lowered without any hassle.
In addition, the table board can be used or stored simply by raising and lowering it, and there is no need to install hollow tubes in the four corners of the vertical hole or attach feet to the four corners of the table board, so it is not necessary to install or assemble the table board. Effects such as making under-floor storage work simpler and easier can be obtained. In addition, in this invention, since the support column is installed approximately in the center of the support frame, the extendable legs can be fixed in an extended state by attaching the extendable legs along the outer surface of the support frame. , Therefore, it also has the effect of being able to hold the table board in a used state.
