ABSTRACT:
Gravity actuated door safety devices, which prevent injury to fingers and pet's tails, are provided. A swinging door safety device comprises a pair of spaced parallel bars connected to one another at one end by a crossbar. At the opposite end of each bar, a counterweight is provided. Each bar has a ring attached at a point between the first and second ends. With the rings mounted to oppositely facing door knobs such that the crossbar spans the leading edge of the door, gravity acting on the counterweight biases the device to rotate such that the bars extend outward from the leading edge and prevent closure of the door by contacting the door jamb. The device is manually rotatable to a position wherein the bars do not extend forward of the door leading edge in order to fully close the door. A sliding door safety device comprises a mounting bracket secured near the leading edge of the sliding door. A lever is pivotally mounted to the bracket and rotatable between a stop position and a retracted position. Gravity acting on the lever automatically deploys the lever to the stop position when the door is opened due to the lever geometry.
