Patent number: 7740309Abstract: A folding chair utilizes a gear train to control a folding motion and to achieve a compact closed form. While holding a handle integrated into a backrest, the weight of the chair allows it to open and unfold automatically into an open position. The folding chair locks in place in the open position. To refold the chair, a button is depressed to release the lock and the seat is pulled toward the backrest. The gear train refolds the front and rear legs. In the compact folded position, the lightweight chair can be carried with one hand in a relaxed position, similar to an attache case. The handle is contoured so that it is possible for an adult to carry two chairs back to back in each hand.Type: GrantFiled: May 16, 2008Date of Patent: June 22, 2010Inventor: Robert P. Mayercheck
