Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seat chair, and more particularly to a seat chair that can be used in various ways.

[0002]

2. Description of the Related Art Chairs are widely used in Japanese life. In a conventional seat chair, a backrest portion is provided on a seat portion so as to be able to be turned upside down, and an armrest is attached to this in some cases. However, the conventional seat chair only considers how to use the chair so that the backrest is tilted at the most, and cannot be used for a long time. Especially, in the chair with armrest, the sitting position,
There was also the problem that even the posture was restricted and it was inconvenient.

[0003]

DISCLOSURE OF THE INVENTION The present invention solves the drawback of the conventional seat chair in that the method of use is fixed,
It is an object to provide an easy-to-use seat chair that can be used more freely and in various ways.

[0004]

Means for Solving the Problems As a result of research to eliminate the drawbacks of conventional seat chairs, particularly seat chairs with armrests, the present inventor has found that the backrest portion or an auxiliary rest portion (such as an armrest) (Sometimes simply referred to as the "rest") can be freely rotated independently of the seat, so that the seating posture is not restricted, and the auxiliary back rests on the feet. The present invention has been completed by finding that it can also be used as a stand or the like and can be used in various ways.

That is, according to the present invention, there is provided a seat chair having a base portion and a seat portion rotatably attached to the base portion, and a leaning portion attached to each of the base portion and the seat portion so as to be able to tilt up and down. Is provided.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in more detail with reference to the drawings showing embodiments of the present invention. 1-10
It is a figure showing the sitting chair which is one example of the present invention. In the seat chair of this embodiment, a base portion to which an auxiliary backrest portion is attached so as to be able to tilt up and a seat portion to which a backrest portion is attached so as to be tiltable are attached so as to be rotatable in their planes. In the figure, 1 is a base portion, 2 is a seat portion, 3 is a backrest portion, 4 is an auxiliary leaning portion, and 5 is a plane rotary plate.

FIG. 1 is a side view of the external appearance. In FIG. 1, 1 is attached so that 4 can be tilted up and 2 is attached so that 3 can be tilted up. Then, 1 and 2 are rotatably connected by 5. The sizes of 1 and 2 are not particularly limited, but they have almost the same area, and when 2 rotates, it becomes 4
The size is preferably such that it does not come into contact with. Also, 3
The ratio of the heights of 4 and 4 is not particularly limited, but 4 is preferably about 1/2 to 1/3 of the height of 3. Note that, as in the case of a normal seat chair, the reference numerals 2, 3 and 4 are formed by wrapping those frame structures, which will be described later, with an elastic body such as urethane, and further with a cloth, vinyl cloth or the like.

2 and 3 are a side view and a plan view showing the frame structure of the seat chair of FIG. In the figure, 6 is a base frame, 7 is a seat frame, 8 is a back frame, and 9 is a back frame.
Indicates an auxiliary leaning skeleton, and 10 and 11 are gears for making the skeletons 8 and 9 tiltable. 2 shows a state in which 8 is rotated 180 degrees with respect to 9, and FIG. 3 shows a state in which 8 is rotated 90 degrees with respect to 9.

In the drawing, the plane rotary plate 5 is provided with a rotary shaft vertically between two base surfaces so that the base surface can be rotated 360 °. The base surfaces of the flat rotary plate are fixed to 6 and 7, respectively, so that 6 and 7 can be rotated while having an appropriate friction. Also, 10
As the gears 11 and 11, the gears for multi-stage reclining generally used for chairs can be used.
With this gear, 8 and 9 are 0 to about 90 relative to the plane.
It is possible to keep the angle at any angle.

FIGS. 4 to 10 are views showing examples of usage of the chair according to the present invention. FIG. 4 and FIG. 8 are drawings showing a usage state as a seat chair with a footrest.
For use in such an embodiment, 2 may be rotated with respect to 1 and 4 may be placed at a position of 180 ° with respect to 3, and the angles of 3 and 4 may be arbitrarily adjusted. According to this aspect, unlike the conventional seat chair, since all the feet can be placed on the seat chair, the center of gravity of the body does not enter into 2 and leans toward 3 without becoming unstable. .

FIG. 5 and FIG. 9 show a mode of use as a seat chair with armrests. To use in such a mode, 2 is rotated with respect to 1 and 4 is converted into 3 It should be at a 90 ° position. 4 as this armrest
Can be taken to any position on the left or right.
Also, the angle of 4 can be changed.

Further, FIGS. 7 and 10 are views showing a mode of use as a sleeping chair. In order to use in such a mode, it is sufficient to place 4 at a position of 180 ° with respect to 3, tilt 3 and adjust 4 to a suitable angle as a pillow as shown in FIG.

Furthermore, FIG. 6 is a view showing a mode of use as a normal seat chair. In order to use in this manner, 4 should be placed at 0 ° with respect to 3,
The 4 hides behind the 3 and is unobtrusive.

11 to 13 are views showing a seat chair according to another embodiment of the present invention. In the seat chair of the present embodiment, a base portion 1 to which a backrest portion 3 is attached so as to be tiltable and a seat portion 2 to which an auxiliary backrest portion 4 is attached so as to be tilted are attached so as to be rotatable in their planes. It is a thing. All symbols in the figure have the same meanings as described above.

FIG. 11 is a side view of the appearance.
The structure is the same as that of the seat chair of the first embodiment except that 4 is attached to 2. Further, FIG. 12 is a drawing showing a use state as a seat chair with a footrest, and FIG. 13 shows a use state as a seat chair with an armrest, both of which are the seat chairs of the first embodiment. It can be used like a child.

14 to 18 are views showing a seat chair according to another embodiment of the present invention. The chair of this embodiment is
The auxiliary back portion 4 and the backrest portion 3 are attached to the base portion 1 and the seat portion 2, respectively, having the same size and the same height without distinction from each other. All symbols in the figure have the same meanings as described above.

FIG. 14 is a side view of the appearance, which is the same structure as the seat chair of the first embodiment except that the sizes and heights of 3 and 4 are the same. FIG. 15 is a view showing a use state as a seat chair with a footrest. To use in such a mode, 2 is rotated by 1 and 4 is rotated by 180 ° with respect to 3. It may be placed at a position and the angles 3 and 4 may be adjusted arbitrarily.

16 to 18 show a mode of use as a corner type chair. In order to use in such a manner, it is sufficient to rotate 2 with respect to 1 and position 4 with 90 ° with respect to 3. In this case, the person using the chair will be seated in the triangular space formed by 3 and 4, but 3 and 4 serve as an armrest at the same time as a backrest (waist), so it is comfortable. You can relax.

[0019]

Since the seat chair according to the present invention is provided with the backrest portion and the auxiliary leaning portion which can be tilted up freely, it is possible to adjust the positions of the backrest portion and the auxiliary leaning portion and their angles. It is possible to use various modes, and it is extremely convenient because it can be used according to the application and mood at that time.
