The present invention relates to a safety device for preventing outward protrusions from an elevator door frame, and preventing hand jamming by giving off a warning light or a warning sound so as to warn a passenger of hand jamming while having a simple structure by using magnets, the safety device allowing a first magnet (50) and a second magnet (52) to approach each other such that current runstherethrough so as to stop the operation of an elevator hall door (D) or control the opening/closing speed thereof, while allowing a rotary frame (30) to rotate when the hand of a person is jammed ina gap between the door frame and a door, thereby preventing the hand of the person from entering the gap, and allowing the rotary frame (30) to rotate outward by a repulsive force between the same magnetic poles of the first magnet (40) and the second magnet (52) when external force acting on the rotary frame (30) disappears, and, at this point, allowing a stopping protrusion (32) of the rotary frame (30) to be caught by a stopper (42) of a support frame so as to prevent the rotary frame (30) from protruding outward from the door frame (10).

    本发明涉及如下的防夹手的安全装置,即,防止转动框架向门框外侧突出,由于利用了磁铁,结构变得简单,进行警告或发出警告音来警告乘客被夹手来防止夹手,若人的手被门框和门之间的间隙所夹到,则转动框架(30)在进行旋转的过程中,第一磁铁(50)与第二磁铁(52)相互靠近并通电来停止电梯厅门(D)的工作或控制开闭速度,由此防止人的手被上述间隙所夹到,若作用在转动框架(30)的外力消失,则借助上述第一磁铁(50)与第二磁铁(52)的相同磁极的斥力,转动框架(30)向外侧旋转,在此情况下,转动框架(30)的卡定部(32)被卡在支撑框架的挡止部(42),以此防止转动框架(30)向门框(10)外侧突出。
