Abstract: A non-key operated lock for the door of an occupied room comprising a vertically elongated prop member pivotally mounted to a guide member at its upper end for oscillation about a horizontal axis for movement between a first inoperative downwardly and outwardly inclined position with the lower end of the prop member spaced above the lower marginal edge of the door and a second operative position with the lower end of the prop member swung toward the door and projecting at least slightly below the door lower marginal edge for engagement with a horizontal surface, such as a floor, over which the lower marginal edge moves when the door is moved toward the open position thereof.

Abstract: A base is provided for stationary mounting from a door and includes an elongated upright guide for positioning against the surface of the door which faces in the direction in which the door is moved toward the open position and with the guide located adjacent the lower marginal edge portion of the door near the free swinging edge thereof. A vertically elongated prop member is pivotally mounted at its upper end from an upper portion of the guide for oscillation about a horizontal axis generally paralleling the door surface and for movement between a first inoperative downwardly and outwardly inclined position with the lower end of the prop member spaced above the lower marginal edge of the door and a second operative position with the lower end of the prop member swung toward the door and projecting at least slightly below the door lower marginal edge for engagement with a horizontal surface, such as a floor, over which the lower marginal edge moves when the door is moved toward the open position thereof.

Abstract: An occupant safeguarding door stop for use on the interior surface of the lower edge portion of a sliding door or window or vertically hinged inwardly openable door has a base securely mountable on the interior surface of the door in a portion thereof adjacent to but above the level of a sliding door or window, or a lower edge portion of the vertically hinged door. A rigid leg member aligned with the base is pivotally joined to the base, and has a foot portion arrangeable for being forcibly pressed and readily actuated toward a gripping portion engaging the overhead frame of a sliding door or window, or a floor associated with the door by foot or hand applied pressure.

Abstract: An elongated wedge member is pivotally supported at its minor dimension end on the free swinging edge of a door for swinging relative to the door about an axis generally paralleling the axis about which the door may be swung and for movement of the wedge member between first and second active and inactive positions with the wedge projecting outwardly of the inner side of the door and swung toward the hinged edge of the door overlying the inner side thereof, respectively. In addition, an elongated tapered and open-sided channel member is provided and has its minor dimension end pivotally supported from the jamb of the aforementioned door for swinging about an axis generally paralleling the pivot axis of the door and movement between first and second active and inactive positions with the channel member projecting outwardly of the inner side of the jamb and swung away from the door overlying the inner side of the jamb.
