  • Patent number: 4475753
    Abstract: A latch member is mounted on the free swinging edge of a door and a mount is supported from a door frame toward which the door free swinging edge is moved to the closed position. The mount is supported for oscillation about an axis paralleling the door frame portion and an elongated hasp has one end pivotally supported from the mount for oscillation about an axis normal to the axis of oscillation of the mount and the other end of the hasp includes structure for latchingly engaging the latch member. In addition, the latch member is supported from a door edge mounted support and the longitudinal mid portion of the hasp and the mount include co-acting structure operable to interlockingly engage with each other and lock the door in the closed position. The hasp, when the end thereof remote from the mount is engaged with the latch member, is operative to allow slight movement of the associated door toward the open position and to prevent the door from being further opened.

The upper upstanding flange includes horizontally outwardly projecting guide structure extending over and outwardly beyond the horizontal flange and an upstanding blade is dependingly supported from the guide structure for movement therealong toward and away from the side of the upstanding flange facing the direction in which the lower horizontal flange projects. The lower marginal edge portion of the blade is spaced slightly above the plane of the lower horizontal flange and is therefore movable inwardly over the lower horizontal flange toward the upstanding flange.
