Abstract: A security device for obscuring an opening defined by a frame (100) is provided comprising a door panel portion (1) forming at least a part of a door which, in use, is supported relative to the frame. The door panel portion has a front face and a rear face and an aperture provided therein, a lock retaining member (2) having a first lock receiving aperture (6) provided therein and a second lock receiving aperture (7) provided therein. Each lock receiving aperture is adapted to receive a lock and the lock retaining member is adapted to be secured to the rear face of the door panel portion in at least a first and a second position and in which first position the first and second lock receiving apertures are visible through the aperture in the door panel portion, and in the second position only one of the lock receiving apertures is visible through the aperture.

Abstract: A locking ring includes two semi-annular ring portions with a U-shaped cross section. The locking ring serves to retain an electric meter in its meter socket in a manner which is well known. Both ends of each ring portion terminate in housings, each housing having an axial lock receiving aperture therethrough. When the ring halves are brought together to form a complete circle, the clockwise-most and counter-clockwise-most housings slide over each other until their lock receiving apertures are in axial alignment. A barrel lock can then be inserted into each of the two sets of aligned apertures, to secure the locking ring against opening. When a barrel lock is removed from either set of apertures, the ring can be opened at that location and removed from the meter.

Complete sealing with substantially increased security against unauthorized access to the door lock is attained in that the door lock takes the form of a casement lock and the cover lock that of a cylinder lock, a partial cover is secured to the lock plate which overlaps with the bolt cover in the locked position at the contact point and forms a sealed lock cover, and a cover for the cylinder lock is rotatably fitted on the bolt cover.

Abstract: An improved safe deposit assembly including an outer housing, a removable inner container, and one or more lock devices which may be in signal communication with a time-delay device for securing valuables within. To unlock and remove the inner container from the outer housing, a separate cover is slid in to a slot on the outer housing. The cover locks a lock before releasing a latch, and neither the lock or latch are accessible until the container is removed from the housing. But a first lock must be unlocked before the cover may be slid in. The first lock may be in signal communication with a time delay to device to thwart robbery attempts. As the cover is slid in it first becomes trapped by a spring lock on the inner container and then it releases a second spring bolt lock that both seals the inner container and releases it from the outer housing. The sealed inner container may only be opened by unlocking the lock device.
