Abstract

Disclosed is a safety device for an opening/closing door in which a door framework is assembled with a door flap by a hinge so as to open and close the door flap while rotating the door flap about the hinge, including: an inside tension plate member 11 fixed to an edge of a door flap 100; an outside tension plate member 12 spaced away from the inside tension plate member 11 in a predetermined distance; a sliding bar 13 formed between the inside tension plate member 11 and the outside tension plate member 12 and capable of sliding in a longitudinal direction; an inside tension bar 14 for connecting the inside tension plate member 11 and the sliding bar 13 in which one end is rotatably connected to the sliding bar 13 by a rotation pin 131 and a torsion spring 132 and the other end is rotatably connected to an inner side bracket 113 fixed to the inside tension plate member 11 by a hinge pin 111; and an outside tension bar 15 for connecting the outside tension plate member 12 and the sliding bar 13 in which one end is rotatably connected to the sliding bar 13 by a rotation pin 131 and a torsion spring 132 and the other end is rotatably connected to an outside bracket 123 fixed to the outside tension plate member 12 by a hinge pin 121. Further, the inside tension plate member 11 includes inside front and rear surface cover plates 16 and 16a on a front surface and a rear surface, respectively, and the outside tension plate member 12 includes outside front and rear surface cover plates 17 and 17a on a front surface and a rear surface, respectively. The safety device can appear and disappear according to applying or removing exterior force to or from the outside tension plate member 12 so as to hurt and fracture someone, even when a finger has been caught between the door framework and the door flap.
