SEMI-AUTOMATIC FOLDING APPARATUS FOR STAND CHAIR OF MOVABLE TYPE

摘要

A semi-automatic folding device for a movable grandstand according to the present invention includes a first support plate, and a second support provided under the first support plate and slidably moved to one side in the horizontal direction with respect to the first support plate to be drawn out or accommodated. plate; a folding chair part provided on the first support plate; and an unlocking movable part for unlocking the folding chair part with respect to the first support plate when the second support plate is slidably moved with respect to the first support plate and accommodated therein. and a semi-automatic folding module for rotating the folding chair part by the unlocking movable part. In the semi-automatic folding device of the movable grandstand according to the present invention, the unlocking movable part is inevitably operated in the process in which the second support plate is accommodated with respect to the first support plate, and thereby the folding chair part can be automatically folded. The workload and device operation time of the device can be reduced, and equipment such as a separate electric motor is eliminated, thereby simplifying the device structure and reducing the device cost compared to the prior art.
