Description

[Detailed explanation of the invention] (a) Industrial application field This invention is a horigotatsu that can be used to do office work or keep warm while sitting with legs stretched out at home. It is designed to be able to be raised and lowered.

(b) Prior Art Previously, the same applicant has filed a prior application regarding a lifting-type horigotatsu.

For example, Utility Application No. 59-106989 (Utility Application No. 61-21201)
(Refer to Publication No.).

(c) Problems that the invention aims to solve However, in the conventional elevating type horigotatsu, the top plate of the low table is supported by a single telescoping column installed below and can be moved up and down. It was hot, so when I started the lift motor, the top plate rotated along with the motor, and while it was still warmed by the kotatsu,
If the lifting mechanism was activated due to an erroneous operation and the top was lowered, there was a risk that Person A's legs, which were hanging inside while sitting, could get caught between the floor and the top and be injured.

The present invention is intended to eliminate such inconveniences.

In addition, for other purposes, the low table 1 can be used as a heating device.
In addition to using a low table 1 in a normal Japanese-style room, we also provide a low table 1 that allows people with leg disabilities to sit with their legs stretched out. It is necessary that the entire low table 1 can be removed in order to avoid creating obstacles during the stage of putting your feet in and sitting down.

The present invention takes into account the convenience of sitting at a table in such home treatment.

(d) Means for solving the problem The purpose of the present invention is as described above. Next, the configuration for achieving the purpose will be explained.

A rectangular box-shaped furnace box with an open top is placed on an elevating lift device placed in a lift storage under the floor. The leg portion 1a is placed thereon.

(E) Embodiment The purpose and structure of the present invention are as described above. Next, the structure of the embodiment shown in the attached drawings will be explained.

Figure 1 is a side cross-sectional view of the lifting-type Horikotatsu of the present invention, Figure 2 is a side cross-sectional view showing the safety in the event that the kotatsu is stored with the foot inside due to an error, and Figure 3 is a side cross-sectional view of the horigotatsu of the present invention. Side sectional view of the stored state,
FIG. 4 is a perspective view showing the top surface and floor surface 5 of the low table 1 in the same stored state, FIG. 3 is a plan sectional view showing the relationship with the upper surface of the side plate 2. FIG.

The overall configuration will be explained with reference to FIGS. 1, 2, and 3.

An elevating lift space B is formed between the floor surface 5 and the ground surface by concrete blocks or the like.

The vertical lift space B has an outer wall portion formed by a side wall 8 and a bottom wall 20, and has a lift storage body inside. The lift storage body is configured in a square shape by the lift storage body side plate 9 and the lift storage body bottom plate 18.

A lower seal 16 is fixed to the upper surface of the lift housing bottom plate 18, and an x-shaped lift device is interposed between the lower seal 16 and the upper rail 15 fixed to the lower surface of the furnace box bottom plate 3.

The x-shaped lift device is composed of cross links 10 and 11.
One end is connected to the upper rail 1 by pivot shafts 12 and 13.
5 and one end of the lower rail 16.

Rotating rollers 14, 16 are pivotally supported at the other ends of the cross links 10, 11, and as the elevating cylinder 4 expands and contracts, the cross angles of the cross links 10, 11 change, and along with this, the rotating rollers 14, 16 change.
16 slides while in contact with the upper rail 15 and the lower rail 16.

With this configuration, the furnace box body placed on the elevating and lowering lift device is moved up and down.

The furnace box body is configured in a square shape similar to the storage body, and defines a foot space C therein, and is fitted into the inner surface of the storage body.

The furnace case is composed of a furnace case side plate 2 and a furnace case bottom plate 3, and as shown in FIG. It is constructed in such a way that there is a step difference.

Because of the presence of the step of height a, the structure is such that the table 1 does not shift when the leg portion 1a of the table 1 is placed on the side plate 2 of the furnace box body. .

In the present invention, the furnace case side plate 2 and the low table 1 are completely separate bodies, and are simply placed on the furnace case side plate 2.

The fixing of the low table 1 to the side is done at the height a mentioned above.
This is done by

With this configuration, even if the elevating/lowering lift device is lowered due to an erroneous operation while the person A is seated with his/her feet inserted as shown in Fig. 2, the bottom surface of the low table 1 will not reach the top of the feet. The low table 1 is placed on the hearth box side plate 2 without pushing the feet down.
They become separated from each other.

Due to the separation of the furnace box side plate 2 and the low table 1, the human A
This eliminates the risk of shearing the legs.

In addition, when a person with lameness, such as a home treatment patient, wants to sit at table 1 with his or her legs stretched out, he or she may remove table 1 and table space D to make it wider, and then sit with his or her legs stretched out. After the table is inserted, the low table 1 can be placed thereon.

Reference numeral 19 is a structural frame that supports the floor surface 5, and 25 is a frame portion that is constructed as a rectangular frame on the floor surface 5.

As shown in FIG. 4, when the horigotatsu of the present invention is stored, the upper surface of the low table 1 and the upper surface of the floor surface 5 are constructed so as to coincide with each other.

As shown in FIGS. 1 and 5, if a kotatsu futon is placed over the low table 1 and the top plate 7 is placed on it, it becomes a heating device in winter.

As mentioned above, when used as a low table 1 for a home therapist, the kotatsu futon can be omitted.

(f) Effects of the invention Since the invention is constructed as described above, it has the following effects.

First, since the furnace box side plate 2 and the low table 1 are completely separate and can be separated, even if the furnace box falls due to an erroneous operation with the person A putting his/her foot in, the
With the low table 1 placed over the feet of the person A, the two are separated, eliminating the risk of injury to the feet.

Second, even if home therapists cannot sit at the low table 1 with their legs stretched out, by making it into a horigotatsu shape, they can stretch their legs and work at a desk in a Japanese-style room, allowing them to do desk work in a Japanese-style room. Because you sit at a lower position relative to the floor than when sitting on a chair and desk, you can maintain a stable posture.

In this case, the low table 1 can be removed when sitting down or standing up.
It is something that you can put your feet in without worrying about it.
