发明名称 Safety lock for folding chair
摘要 A safety lock for folding chair includes a top portion and two lateral wall portions to define an open-bottomed receiving space therebetween. The safety lock is mounted to a rear end of a seat frame tube of the folding chair by extending a shaft pin through two shaft holes provided at a rear end of the safety lock and two through holes provided on the seat frame tube, so that the safety lock may be pivotally turned about the shaft pin between a lock position, in which the seat frame tube is clamped in the receiving space and the folding chair is prevented from collapsing, and a release position, in which the safety lock is turned away from the seat frame tube. The two lateral wall portions have two bottom edges that are always located at finger accessible open positions to facilitate easy turning of the safety lock.
