ABSTRACT:
A safety device for use in indicating whether a closure member, such as a door or window, disposed in a frame defining an opening in a room of an edifice, has been opened, comprises an elongated, unitary, relatively thin planar stationary member secured to a face of the closure member adjacent the frame at an angle to the horizontal, the stationary member having one end disposed adjacent the frame and an other end remote from the frame with the one end being at a higher elevation than the other end and an elongated, unitary, relatively thin planar movable member pivotally secured to the first member adjacent the other end of the stationary member for pivotal movement about an axis extending substantially at right angles to the planes of the first and second members, the movable member having a rounded edge remote from the one end thereof and is of a length such that the edge abuttingly engages and is partially supported by the frame, the movable member being movable under the influence of gravity from a first position whereat the movable member completely conceals the stationary member from view and the edge means engages the frame when the closure member is closed to a second position when the closure member is opened whereat the movable member exposes the first member to view and wherein the stationary and movable members are of different colors.
