BRIEF SUMMARY
DESCRIPTION
1. Technical Field
The present invention relates to a combination chair which can be used as one chair by combining a plurality of chairs.
2. Background Art
In a dining room, for example, a table and a plurality of chairs are provided. Usually, the chairs are prepared so as to correspond to the number of members in the family. Therefore, in the case where there is a guest or the like, and the number of people using the dining room increases, the number of chairs must be increased in accordance with the number of guests added.
It is possible that extra chairs are always prepared for guests in advance; however extra chairs occupy some space in the room. Therefore, when they are not used, they take up much space. In a house of a narrow living space, it is, in many cases, difficult to reserve a space for placing extra chairs.
SUMMARY OF THE INVENTION
An object of the present invention is to provide a combination chair, in which a plurality of chairs are stacked up into one chair, or vice versa, and therefore the number of chairs can be increased or decreased in accordance with an increase or decrease in number of people using chairs, thus avoiding the occupation of an extra space.
Another object of the present invention is to provide a combination chair in which chairs, when they are stacked up, can be combined into one chair without looseness.
According to an embodiment of the present invention, there is provided a combination chair comprising a plurality of chairs, characterized in that: said plurality of chairs each having a seat portion supported by legs and a backrest provided on the seat portion, and the backrests of the chairs are jointed to be adjacent to each other by one side in the width direction, and lengths of the legs are set so that lower ends thereof coincide with each other.
According to another embodiment of the present invention, there is provided a combination chair comprising a plurality of chairs, characterized in that each of the chairs has a seat portion supported by legs and a backrest provided on the seat portion, the seat portion of each chair is supported by said legs at such a height that the seat portions are stacked one upon another in an up-and-down direction, and inner surfaces of the legs of a chair situated on an upper side are fitted to outer surfaces of the legs of a chair situated on a lower side when the chairs are combined so that the seat portions are stacked up.
According to still another embodiment of the present invention, there is provided a combination chair comprising of a plurality of chairs, characterized in that each of the chairs has a seat portion supported by legs and a backrest provided on the seat portion, the backrest of a chair whose seat portion is located on an upper side, and the backrest of a chair whose seat portion is located on a lower side is fitted in a frame of the backrest of the chair whose seat portion is located on the upper side when said plurality of chairs are combined so that the seat portions thereof are stacked up in the up-and-down direction.
With the above-described structures, a plurality of chairs can be used separately as a single chair, and they can be combined together to be used as one chair. Therefore, the present invention can follow an increase/decrease in the number of users.
When the plurality of chairs are combined together, the slipping movement in the up-and-down direction and horizontal direction can be suppressed, and therefore the combination chair can be easily used as one chair.
