The present invention relates to a device for drawing in and out a chair for a stall table. To this end, according to the present invention there is provided a device for drawing in and out a chair for a stall table in which the chair is drawn in or out by a supporting leg of a table leg supporting a top plate of a table. The table includes a leg on a low surface of the top plate. The table leg includes a horizontal member extending outwardly from low ends of two supporting members and the supporting leg coupled to an end of the horizontal member. In addition, the device for drawing in and out a chair includes a hinge device provided at an upper portion of the supporting leg and a chair guide coupled to the hinge device through a connecting bar. The hinge device includes a hinge cap coupled to one side of the connecting bar toward the upper portion of the supporting leg. The chair guide is coupled to the opposite side of the connecting bar and a hinge fixing device is forcefully inserted into the supporting leg placed at an inner upper side of the hinge cap. A hinge cap supporting cover is coupled to an upper portion of the hinge cap, and a pneumatic cylinder is provided between the hinge cap supporting cover and the supporting member. A stopper is provided at a low portion of the hinge cap. Therefore, the structure is simple so that the producing cost may be reduced. In addition, the pneumatic cylinder may prevent the chair guide from being excessively folded and unfolded, so that the operation reliability is improved. |
