Abstract
A safety door barrier includes a barrier post, barrier body, and a barrier stopper. The barrier post has upper and lower seats at the upper and lower ends thereof respectively. The upper seat has an upper stop with an upwardly slanted bottom and a lower stop with a downwardly slanted top. The lower stop has a lower stop hole, and the lower seat has a lower seat hole. The barrier body has an upper projection and a lower projection corresponding to the lower stop and the lower seat respectively, an upper pivot and a lower pivot extending downwardly from the upper and the lower projections respectively corresponding to the lower stop hole and the lower seat hole, and a latch device composed of a latch and a spring disposed at a lateral side of the barrier body opposite to the upper projection. The barrier stopper provides a latch hole corresponding to the latch device. The barrier body can be raised up and pushed forward or backward to open. The latch is inserted into the latch hole to lock the barrier body as soon as the barrier body is back.
