Description

[Detailed explanation of the invention] (a) Purpose of the invention <Field of industrial application> The invention is a mobile or portable kotatsu,
In particular, it relates to a hori-kotatsu type kotatsu with an assembled chair.

<Prior art> Traditionally, mobile kotatsu were built in the form of a tower, placed on tatami mats, the floor, and equipped with an independent heating element inside, or installed on the ceiling inside the tower, with a kotatsu futon, etc., hung from above. This type of kotatsu is convenient because one kotatsu can double as a heating system for each room. Young people tend to avoid using kotatsu because they require sitting down on the tatami and inserting the legs horizontally, and for this reason, some families keep Yagura kotatsu that are no longer in use. Not a few.

In addition, the hori kotatsu is a sitting type that is comfortable for the body to use for long periods of time, but it is not easy to install it in an existing room, and it is impossible to install it in modern condominiums. I can't even try. There are problems such as it takes up a relatively large amount of space.

<Problems that the invention aims to solve> Therefore, the present invention takes advantage of the heat retention, thermal efficiency, and ease of use of the hori-kotatsu, and creates a kotatsu with an assembly type chair that combines the movability of the kotatsu and the ability to be installed anywhere. We have developed a movable sitting hori kotatsu that eliminates the inconveniences of conventional Yagura Kotatsu, and that can be disassembled into individual parts and stored when not in use, requiring no space for storage. The purpose is to provide.

(b) Structure of the invention <Means for solving the problems> The invention has each of the constituent requirements described below in order to achieve the above purpose.

(1) Four rectangular plates are joined at right angles to each other at opposite sides, and can be assembled and disassembled.
A rectangular frame having the same length as between the adjacent legs of the kotatsu tower is formed, and a shelf board that supports each leg end of the kotatsu tower is attached to the middle part of the four inner corners of the frame to connect the frame and the kotatsu tower. and,
It is assembled through the legs of a tower, and the upper edge of each side of the rectangular frame is provided with protrusions that can be engaged and detached from engagement grooves provided on the lower surface of the seat plate of the chair with folding legs. Mobile sitting kotatsu.

(2) No. (1) above, in which each leg end of the kotatsu tower is removably screwed to the middle of the four corners inside the rectangular frame.
The movable sitting hori kotatsu mentioned in the section.

(3) When assembling and disassembling four rectangular plates, use the locking holes of the plates with locking holes installed along the opposite sides of each rectangular plate.
The movable seat hori kotatsu according to item (1) or item (2) above, which is arranged in series by forming rectangular frames, and is configured by inserting and removing pins into the locking holes. .

<Function> Four rectangular plates are assembled to form a frame, which is installed on the tatami mat or floor (hereinafter referred to as the floor).A heat source is housed inside, and a kotatsu tower is placed on the top of the frame. In addition, the protrusion provided approximately at the center of the upper edge of each side forming the frame is fitted into the engagement groove on the lower surface of the seat plate of the chair with folding legs, and the legs of the chair are opened and the seat plate is connected to the protrusion. After assembling it to support the space between it and the floor, cover it with a kotatsu futon or a blanket to keep it warm so that at least the upper edge of the frame is hidden from above.

The heat source is usually an electric heating element, which is installed on the bottom floor inside the frame to warm the feet.The frame is designed to block the warm air inside from the cold air near the floor, so the frame is equipped with insulation. It is desirable to install them in parallel.
By bringing the upper edge of the frame into close contact with the lower surface of the seat of the chair, and by using a thermal blanket to close the gap between the frame and the kotatsu tower, excellent heat retention is achieved by preventing hot and cold air from entering and exiting from the inside. It can provide good performance and thermo-economic efficiency.

This seated Horigotatsu can be used while sitting down on a chair like a regular Horigotatsu, so you can use it for a long time without feeling any resistance even with a few layers, and without making your legs numb. It is easy to use, and has a remarkable effect on keeping the legs warm. Since it is mobile, it can be placed under the dining table to heat the legs and other areas during meals. Furthermore, if the size of the frame is appropriate, a used kotatsu tower can be reused.

It has the same usability as a horigotatsu, but can be moved to another location, and can be used in places where a full-fledged horigotatsu cannot be installed due to its structure. This frame has enough room to fit up to eight chairs, so even a large family can use it without any inconvenience.

Since the frame body and the chair can be assembled and disassembled, they can be disassembled and stored when not in use, saving space for storage.

<Example> Fig. 1 is an assembled perspective view of the movable seated moat kotatsu of the present invention, excluding the tower, and Fig. 2 is an enlarged perspective view of the corner of the frame. is a rectangular frame board made of thick plywood, etc., and is approximately 35 to 40 cm in height and 70 to 75 cm in width. Plates 2, 2'... with locking holes are provided at the top and bottom along the sides, and when the adjacent frames 1, 1 are joined at right angles on each side, the plates 2, 2' are locked. The stop holes are arranged in series, pins 3, 3, . If necessary, attach heat insulating material to the outside of the frame. Reference numeral 4 denotes a shelf plate supporting the leg end of the kotatsu tower, which has a triangular plane and is screwed to the frame plate 1 at the middle or slightly above each corner of the frame in the height direction.

FIG. 3a shows an enlarged plan view of that part, with the leg ends of the kotatsu tower resting on the support leg plate 4. Therefore, the distance between adjacent legs of the kotatsu and the width of the frame board 1 are approximately the same length. In this case, the kotatsu tower is placed on the support leg plate 4 from above the frame and is detachable. If there is no problem even if the kotatsu tower and frame are integrated, please refer to Fig. 3b.
As shown in the figure, the legs of the tower can be screwed to any corner of the frame.

Reference numeral 5 denotes a protrusion provided at the center of the upper edge of each frame 1, which is fitted into an engagement groove bored into the lower surface of the seat plate 6 of the seat chair, which will be described later, and as shown in FIG. It has the effect of placing the tip of the seat plate of the folding chair on and assembling and fixing it. However, in the case shown in the first drawing, only one chair is assembled, and each chair is attached to each frame plate 1 forming the frame body. Can be attached.

Figure 4a shows the unfolded plan view of the seat;
In the figure, 6 is the seat plate of the chair, and an engagement groove 9 into which the protrusion 5 is fitted is bored in the center of the back surface of the seat plate, and the groove has an opening closer to the folding leg 7 side. , the protrusion 5 is guided into the groove 9 from the opening. The rear end of the seat plate 6 is connected to a folding leg 7 via a hinge 8, and the length of the leg is the same as the height of the frame plate 1, so that when the chair is assembled to the frame body, the seat plate 6 is I try to keep it level. Figure 4b is
This is a side view of the chair when the legs are erected. Due to the mounting structure of the hinge 8, the seat plate 6 and the legs 7 intersect at right angles and stop.

Note that the sitting chair may be provided with a backrest if necessary.

Returning to FIG. 1 again, when the folding chair is assembled to the frame, the weight applied to the seat plate 1 is correctly supported by the frame and the legs 7, so that it will not be deformed or damaged. do not have.

As mentioned above, the movable sitting hori kotatsu according to the present invention can be completely disassembled into parts except for the kotatsu tower, so it requires less space for storage and storage when not in use. Further, no special skills are required to assemble it for use, and anyone can easily use it.

(c) Effects of the invention As described above, according to the sitting hori kotatsu of the present invention, it is possible to easily move the equipment to rooms where it is impossible to install a full-fledged hori kotatsu or where it is difficult to remodel. Since it is a seat type kotatsu, it is easy to use and is often used by young people.
If you place it under the dining table, you can eat while heating the legs. Additionally, if you set the top of the yagura gotatsu high, you can place a base plate on top of it and use it as a dining table. Furthermore, depending on the number of family members or users, it is possible to assemble one to eight chairs as desired.

It has better thermal efficiency and is more economical than traditional Yagura Kotatsu.

Since it is an assembly type, it takes up relatively little space when not in use.

It is also possible to reuse an old kotatsu tower by providing a frame and folding chairs.

These and other special functions and effects cannot be expected from the well-known kotatsu towers and horigotatsus.
