Abstract

A locking device includes a base having openings therein for joining the base to a first surface, such as the surface of the door, and a cover hinged to the base plate by a solid bar passing through apertures in flanges near the upper end of the base plate and cover. This solid bar is sufficiently long to engage an opening in a second surface, such as a door jamb. Joined to and extending laterally from the solid bar is a second bar that lies between the flanges of the cover plate, thus confining the second bar to the space between them, and preventing removal of the solid bar from the device. Projecting from the inner surface of the plate and from the inner surface of the cover are lock-receiving flanges having apertures which lie proximate one another when the cover plate is closed against the base. The apertures in these lock-receiving flanges lie at least partly in the same plane, permitting the hasp of a padlock to pass through both, thus locking the cover to the base plate. When the solid bar engages the opening in the second surface, the second bar lies on the side of the lock-receiving flanges nearer the opening. Locking the flanges together prevents disengagement of the solid bar from the opening in this situation.

Dependent claims

Locking means including a base plate and a cover plate hinged thereto, the base plate including:

flanges extending laterally from opposite sides of said base plate, each base plate flange including an aperture near one end of said base plate, the apertures lying at least partly in the same plane, and means for joining the locking means to a first surface;
the cover plate including flanges extending laterally from opposite sides of said cover plate, each cover plate flange including an aperture near one end of said cover plate, said apertures lying at least partly in the same plane;
the cover plate flanges alone, the base plate flanges alone, or both together bridging the spaces between the edges of base and cover plates on said opposite sides;
said base plate and cover plate each including a lock-receiving flange on its inner surface, each lock-receiving flange including a lock-receiving aperture, said lock-receiving apertures lying at least partly in the same plane when said cover plate is closed against said base plate;
first bar means passing through the apertures in the base plate and cover plate flanges and joining the plates hingedly and being sufficiently long to engage a second surface when said second bar means lies on the side of at least one of said lock-receiving flanges nearer the second surface;
and
second bar means joined to and extending laterally from said first bar means at least to the lock-receiving flange on said base plate.
