  • Patent number: 4346924
    Abstract: A briefcase is provided with a two-part releasable fastening device, the first part of which includes a movable fastening member for releasably fastening the parts together. The first part of the device further comprises a ball which, when the case is inverted, is urged by gravity into a retaining position in which it prevents releasing movement of the fastening member. When the lid of the case is uppermost, the ball permits movement of the fastening member to release the second part of the device.

  • Patent number: 4266816
    Abstract: A lock remote control device comprises a lock assembly and a manipulatable unit positioned spaced a distance from the lock assembly. The lock assembly includes a latch lever for selectively locking and unlocking a movable structural element, a first biasing spring for bringing the latch lever in position to lock the movable structural element. The manipulatable unit includes a movable member connected through a latch cable to the latch lever and movable between projected and retracted position, and an actuator operable to permit the movable member to move from the retracted position towards the projected position to bringing the latch lever against the first biasing spring in position to unlock the movable structural element when an external pushing force is applied thereto, but to block the movement of the movable member in the retracted position during the absence of the external pushing force. This movable member is normally biased to assume the projected position by a second biasing spring.
