Description

The present invention relates to stacking chairs, especially armchairs.

Chairs, especially armchairs, are usually stacked from the front, but the chairs are often approached from the rear, and if stacking is not done from the rear, the seats will get in the way and put a heavy burden on the lower back. Additionally, most conventional stacking chairs require the rear legs to be raised to the height of the seat, which is approximately 400 mm, making them extremely difficult to work with.

The chair of Patent Document 1 is a general stackable armchair, but when stacking, it is necessary to lift the back legs to the height of the seat surface. The chair of Patent Document 2 can be lifted at a low height, but if there is a table or the like in front of it, sufficient space must be secured. Although the chairs of Patent Document 3 can be stacked from the rear, they are not intended to be armchairs. Furthermore, there is a problem in that when the legs have a four-legged, three-legged, or two-legged shape, they cannot function as a stacking device.

Therefore, the present invention provides a seat plate receiving member, a seat plate, an armrest and A backrest member integrated with an armrest is arranged. By attaching an integrated armrest and backrest to the inside of the front legs, it is possible to stack them by simply lifting them slightly from the rear, regardless of whether the legs have four legs, three legs, or two legs. In addition, in the case of two legs, by attaching the lower part to the inside of the legs, it can be stacked from the front or the back.

Thanks to the invention, the chairs to be stacked can be placed on the armrests of the chairs to be stacked from the rear, or in the case of two-legged chairs from the front or from the rear or both.
