US Patent 7937806 Door safety device

An apparatus is disclosed for permitting or preventing a panel from closing an opening within a wall. A hinge secures the panel to the wall for pivoting the panel relative to the opening. The apparatus comprises an inverted generally u-shaped frame defining a slot for positioning to the panel. A bar member includes a first end and a second end. A fulcrum pivot is interposed between the first end and the second end for pivotably mounting the bar member to the inverted generally u-shaped frame. The fulcrum pivot pivots the bar member between a generally vertical position and a generally horizontal position. The bar member pivots to the generally vertical position for disengaging the second end from the wall for permitting the panel to close the opening of the wall. The bar member pivots into the generally horizontal position for engaging the stopper end with the wall for preventing the panel from closing the opening of the wall.
