Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outside air blocking structure for a Western-style kotatsu, which is a set of desks and chairs, that is, a set of kotatsu.

[0002]

2. Description of the Related Art In conventional home kotatsu, a home kotatsu hanging hood is generally used as an outside air screen.

[0003]

The Western-style kotatsu desk is taller than the generally used Japanese-style kotatsu, and is a set together with the chair. When sitting on the chair, both sides of the chair, that is, Outside air blocking curtains on both sides of the knee may be lifted greatly from the floor, and outside air may enter. It is uneconomical to use an outside air screening curtain with a considerably large hanging portion on the floor as a preventive measure. There was a problem that it was inconvenient to carry in and out when carrying out a large outside air blocking curtain while being careful not to step on the curtain that drooped down greatly when using it.
In addition, it is essential that the chair that is used in combination with the desk shut off the outside air at the same time as the desk. Furthermore, the entrances and exits of the legs and knees of the desk are generally small, and the backward movement of the chair is necessary for the entrance and exit of the legs and knees. Therefore,
It is possible to enclose all under the chair without leaving a gap with the floor,
In this case, it is difficult to move the chair because there are no chair legs. There is also a problem of outside air intruding through a gap between the chair and feet or a chair with casters that is generally used for the chair and the floor. Further, when the chair is moved, the hanging outside air curtain is hooked on the foot of the chair or is stepped on and pulled in, which causes a problem that the chair does not move smoothly.

According to the present invention, even in a tall Western-style kotatsu, a Western-style kotatsu desk which does not require the above-mentioned considerably large outside air-shielding curtain and has an outside air-shielding curtain of a minimum area and whose legs and knees can easily come in and go out is provided. Furthermore, it is an object of the present invention to provide a Western-style kotatsu with a Western-style kotatsu chair that can smoothly move without any problem even when the chair is moved, by shutting out the outside air from the space between the chairs in the chair that is indispensable for use with the desk. . Further, it can be configured as a desk or chair that is generally used.

[0005]

In order to achieve the above object, in the western-style kotatsu of the present invention, one side of the substantially tunnel-shaped curtain, that is, one side is attached to the peripheral edge of the outside air cutoff point.

[0006] That is, one of the substantially tunnel-shaped curtains is attached to the entrance / exit of the legs or knees of the desk or the heating box accommodated in the desk. Further, one of the opposite sides is provided so as to project from the entrance / exit of the leg. Then, a part is opened so that a person's foot or knee can easily enter and leave from the side surface of the substantially tunnel-shaped curtain that is provided in a protruding manner.

The substantially tunnel-shaped curtain may be formed integrally with the desk or the heating box or the desk by projecting to the outside of the limb entrance / exit periphery of the heating box. Further, it is also possible to form a Western-style kotatsu outside air shielding curtain in which the legs and knees are opened in a conventional outside air shielding curtain and the above-mentioned substantially tunnel-shaped curtain is attached.

Next, as an outside air shielding means under the chair, one of four substantially tunnel-shaped curtains surrounding the entire circumference or at least three sides is attached to the chair, and the other one is projected on the floor and grounded. To shut off the outside air.

In the case where a substantially tunnel-shaped curtain grounding slightly on the floor is attached to the chair, the legs of the chair and the substantially tunnel-shaped curtain are attached so as not to contact each other even when the chair is moved. Alternatively, the feet of the chair can be retracted by the distance.

Further, when a substantially tunnel-shaped curtain greatly hung on the floor surface, which is abbreviated as a curtain, is attached to a chair, as a means for moving the curtain without obstruction without contacting the legs of the chair, the curtain movement described later is performed. Equipment should be installed around the lower part of the foot and knee entrance. In this case, one of the substantially tunnel-shaped curtains can be attached to the chair, and one of the opposite sides can be attached to the bottom surface of the heating room, that is, around the lower portion inside the desk or the heating box accommodated in the desk.

Further, it is possible to connect a part of the substantially tunnel-shaped curtains of the desk and the chair, which will be described later. It is also possible to connect the protruding lower part of the substantially tunnel-shaped curtain attached to the desk to a chair or an outside air shielding curtain provided on the chair and not substantially in the tunnel shape. In addition, it is preferable to provide an expansion / contraction moving device and a seat moving device which will be described later and do not require a hanging curtain. Since the Western-style kotatsu is constructed as described above, the outside air can be shut off by attaching a substantially tunnel-like curtain to a desk, a heating box, a conventional outside air shutoff curtain, or an outside air shutoff portion of a chair. Further, even when the chair is moved, there is no obstacle in the curtain, and it is possible to easily go in and out of the substantially tunnel curtain. Also, the minimum outside air shielding curtain with no waste is sufficient.

Although the substantially tunnel-shaped curtain 13 shown in FIGS. 7 and 8 surrounds three sides, it may surround four sides, that is, the entire circumference.

In FIG. 9, when the chair is retracted, there is no obstacle in the chair foot 11, but even when the chair foot 11 moves forward in the direction of arrow B, the substantially tunnel curtain 13 is stepped on by the chair foot 11. In order to avoid any obstacle such as pulling in, it is shown that they are mounted with a space as shown in the drawing, and are also slightly grounded to the floor surface 30. Therefore, it is possible to block outside air from a slight gap under the chair. In addition, it is preferable to use a soft material for the substantially tunnel-shaped curtain 13.

In the embodiment shown in FIG. 10, one side of the substantially tunnel-shaped curtain 23 is attached to the seat of the chair 5 in (a), and one side of the opposite side, that is, one of the curtain hanging largely on the floor surface, is placed in the heating room 7. To the bottom of the. Then, the hanging curtain moving tool 16 is attached to the lower portion of the chair 5 so that the hanging curtain does not obstruct the chair legs 11.

The bottom surface of the hanging-paper moving tool 16 is attached to the floor surface 30. Then, when the chair 5 is moved forward, the hanging curtain of the substantially tunnel-shaped curtain 23 is adjusted and attached so as to move without sagging as shown in the drawing. The place of attachment may be the lower part of the chair 5 or the lower part of the rigid, substantially tunnel-shaped curtain 15. In addition, chair 5
When retreating, the slack of the flap of the substantially tunnel-shaped curtain 23 is eliminated and the chair leg 11 does not have the above-mentioned obstacle. It should be noted that it is preferable to provide a backward stopper such as a backward stopper on the floor surface 30 at a proper position with respect to the backward movement of the chair leg 11. Further, a fiber rug or the like is suitable for the floor because it blocks the outside air.

In (b), the banner moving tool 1
6 shows a shape of No. 6. That is, the device does not have to have the illustrated shape as long as it is a device that can smoothly move a curtain that hangs largely. Further, the banner moving tool 16 may be separately slidably attached to the floor surface, or may be integrally formed with the lower portion of the chair 5. It is also possible to mount one of the substantially tunnel-shaped curtains 23 on the seat without mounting it on the seat.

The embodiment shown in FIG. 11 is another embodiment of FIG. One side surface of the substantially tunnel-shaped curtain 3 and the side surface or side of the substantially tunnel-shaped curtain 23 are connected by, for example, stitching between the positions C and D. Therefore, when the chair 5 is retracted, as shown in (a), the flap of the substantially tunnel-shaped curtain 23 is extended, and when the chair 5 is advanced, as shown in (b), the flap moving tool 26 is used. Move while hanging the banner. At this time, since C and D are connected to each other, it is shown that slack is also generated between E and F of the substantially tunnel-shaped curtain 3. It should be noted that the substantially tunnel-shaped curtain 3 and the substantially tunnel-shaped curtain 23 on the opposite side surface with respect to the one side surface connected are not connected because the foot and knee of a person come in and go out. Illustration is omitted.

On the bottom surface of the heating box, a retreat stopper 17 is attached so as not to pull the curtain when the chair 5 retreats. Further, a groove 18 is formed in the bottom surface of the heating box 8 between the moving ranges of the banner moving tool 26 as shown in FIG.

The upper part of the banner moving tool 26 is attached to the lower part of the chair 5. The lower tip is configured to slide on the groove 18. Therefore, the banner moving tool 26
Since the lower part of is lower than the bottom surface of the heating box 8, the banner located on the bottom surface of the heating box 8 can be moved without the obstacle.

The embodiment shown in FIG. 12 is still another embodiment of FIG. In (a), C to D
11 is the same as that of the embodiment of FIG. 11, but is not connected, but is formed by the substantially tunnel-shaped curtain 33 in which the protruding lower portion of the substantially tunnel-shaped curtain attached to the desk is continuously attached to the chair. Is. The central portion of the lower side of the hanging curtain of the substantially tunnel-shaped curtain 33 is attached to the desk 1 or the upper end of the front lower part of the heating box 8 as illustrated. As shown in (b), the curtain is adjusted so as not to obstruct the chair legs 11 even when the chair 5 moves forward. Therefore, in the embodiment of FIG. 12, the above-mentioned hanging curtain moving tool is not necessary.

In addition, in the case of connecting the one side C to D in FIG. 11, since the lower portions of the side surfaces E to G of the substantially tunnel-shaped curtain 3 and the side surface of the substantially tunnel-shaped curtain 23 at the same place overlap each other, the substantially tunnel-shaped curtain 23 is formed. It is also possible to cut this overlapping part of the curtain 23. That is, the substantially tunnel-shaped curtain 3 does not necessarily have to be used together with the substantially tunnel-shaped curtain 23 because it guarantees the outside air shielding of the knee side surface. , It is also possible to connect, and it is possible to block the outside air from the side of the knee.

In the embodiment shown in FIG. 13, the expansion / contraction device 19 provided with expansion / contraction means that does not require a banner moving tool.

Spring storage cylinders 29 are provided as expansion and contraction means on both sides of the lower portion of the desk 1 or the heating box 8, and one of the spring 39 and the shaft 49 in the spring storage cylinder 29 is connected. The other side of the shaft 49 and the moving plate 59
And are connected. The expansion / contraction moving device 19 is shown in which an upper portion of the moving plate 59 is connected to the outside air shielding curtain 130, and a lower portion of the moving plate 59 is provided with a long roller 69.

In (a), when the chair leg 11 is retracted, the moving plate 59 is brought into close contact with the chair leg 11 and simultaneously retracts by the spring 39. Further, in (b), on the contrary, when the chair leg 11 moves forward, the moving plate 59 also moves forward while being pushed by the chair leg 11 at the same time. (C)
[Fig. 6] is a cutaway front view showing a main part of a telescopic moving device 19 having a telescopic means.

Therefore, since the outside air blocking curtain 130 under the chair is connected to the upper part of the moving plate 59, there is no need for a space like the above-mentioned hanging curtain. Since the long roller 69 of the telescopic moving device 19 is in close contact with the floor surface 30 as shown in (c), the outside air is shut off. The telescopic moving device 19 is
The long roller 69 is not particularly required as long as the outside air is blocked from the gap of the floor surface 30 and the structure can be smoothly moved. For example, it is possible to attach an outside air blocking curtain to the bottom of the moving plate 59, which slightly contacts the floor surface. Further, the spring 39 is an example of the expansion / contraction means, and the spring 39 may not necessarily be used.

Another embodiment of a Western-style kotatsu table in which a substantially tunnel-shaped curtain 3 is attached to the peripheral edge thereof is shown.

In the embodiment shown in FIG. 15, it is a plan view showing that the leg / knee entrance / exit 22 is opened in the conventional outside air shielding curtain without attaching the substantially tunnel curtain 3 to the desk 1 as described above. . It is possible to configure the outside air blocking curtain 21 in which the substantially tunnel-shaped curtain 3 is attached to the periphery of the leg / knee entrance / exit 22. The perspective view of the outside air blocking curtain 21 having the above-described structure set on a Western table is very similar to the perspective view of FIG. Further, it is possible to open the shape of the foot / knee entrance / exit 32, 42, 52 and attach a substantially tunnel-shaped curtain matching this shape, and it is also possible to provide a foot / knee entrance / exit of this shape on the desk,
Various shapes are possible.

The embodiment shown in FIG. 16 is an embodiment of a western-style kotatsu chair 55 provided with a seat moving device 45.
A detachment preventing male member 75 is attached to the lower portion of the seat 65. Further, a seat pedestal 85 is attached to the upper portion of the chair leg 110. A long roller 95 is attached to the seat pedestal 85 and a detachment preventing female member 105 is attached to both sides thereof, and the detachment preventing male member 75 is inserted and slidable. Therefore, an example of a device in which only the seat 65 can be moved back and forth by the long roller 95 even if the chair leg 110 does not move is shown. Seat 6 as shown in (b)
There is no possibility of the above-mentioned trouble even with a hanging curtain on the floor surface by a substantially tunnel-like curtain attached to the lower part or the upper part of 5.

FIG. 17 shows the above problems when the chair 5 is set by using the conventional outside air shielding curtain 20. As shown in the figure, when the chair 5 is set, both sides of the outside air blocking curtain 20 are pulled laterally as indicated by an arrow H. At the same time, the bottom of the outside air blocking curtain 20 is also lifted greatly as indicated by arrow I, indicating that there is a problem in blocking the outside air. Since the seat of the chair 5 is projected from the desk 1, it becomes higher when a person sits down, and pulling from the side of the outside air blocking curtain 20 and lifting from the bottom is even more difficult.

[0036]

Since the present invention is configured as described above, it has the following effects.

One of the substantially tunnel-shaped curtains is a desk, a heating box, or
By attaching to the periphery of the leg knee entrance of the conventional outside air blocking curtain, the outside air blocking curtain does not pull from both sides or lift up greatly from below, and it also holds the outside air blocking on the side of the knee when sitting, The limit is the outside air curtain.

Further, it is easy to use when used, and the legs and knees can be easily moved in and out without the above problems.

Further, since it is necessary to move the chair, even in a chair in which casters or the like are attached to the legs of the chair, the effect of shutting off the outside air from under the chair can be obtained by attaching the substantially tunnel curtain to the lower part of the chair. Further, if the expansion / contraction moving device / draft moving device / seat moving device is provided, the above-mentioned obstacle due to the hanging curtain does not occur.

It is needless to say that with the structure of the present invention, it is possible to create a dedicated Western-style kotatsu, but it is also possible to use a general desk or chair that is not a Western-style kotatsu as the Western-style kotatsu. .

With the Western-style kotatsu having the structure of the present invention attached to a desk or chair, there is an effect that it is easy to get in and out, does not get irritated, and can concentrate on office work and study.

The above description of the embodiments is for explaining the present invention, and should not be construed to limit the invention described in the claims or to limit the scope thereof. Further, it goes without saying that the configuration of the present invention is not limited to the above-described embodiment, and various changes can be made within the technical scope described in the claims.

For example, it is also possible to connect to a chair without legs on the lower side surface of the substantially tunnel-shaped curtain 3 or to one side of a general flat outside air shielding curtain which is not a substantially tunnel-shaped curtain and is connected to the chair.

Further, the shape of the substantially tunnel-shaped curtain does not necessarily have to be a tunnel shape having a semicircular upper portion, and various shapes can be changed according to the shape of the mounting position of the desk or chair.
