Sliding Patents (Class 70/118)
  • Patent number: 11814877
    Abstract: A conventional safe proper becomes useless when unable to be locked or unlocked, thereby causing a waste of resources. Locks capable of being locked/unlocked are provided to unfasten a common fastening member, so as to open a door or lid from the body, allow each lock to be freely mounted on and dismounted from a lock mounting portion, and dispose a false lock on each lock. An operating means of locking/unlocking any one of the locks is provided to enable persistent use of a common latch disposed at an identity opening of a safe proper.

  • Patent number: 11808057
    Abstract: Electromechanical lock utilizing magnetic field forces. An actuator is moved (1202) from a locked position (260) to an open position (400) by electric power. In the locked position (260), a permanent magnet arrangement directs (1204) a near magnetic field to block an access control mechanism to rotate, and simultaneously the permanent magnet arrangement attenuates (1206) the near magnetic field towards a far magnetic break-in field originating from outside of the electromechanical lock. In the open position (400), the permanent magnet arrangement directs (1208) a reversed near magnetic field to release the access control mechanism to rotate, and simultaneously the permanent magnet arrangement attenuates (1210) the reversed near magnetic field towards the far magnetic break-in field.

  • Patent number: 11208832
    Abstract: An adapter and interface permits a standard mortise lock to drive top and bottom latch mechanisms of a multi-point lock system. An actuator permits in situ adjustment of the top and bottom vertical latch projections of adjusting these projections while the door is hung in the door frame. An installation tool assists in the installation of the vertical rods in a door. A connector and carrier secures the vertical rods to the actuator and permits verification of retention of the rods in a multi-point latching system. A latch dogging indicator allows for end-user adjustment between a single-point lock and a multi-point lock system when desired. These different aspects may be employed in combination or separately with other locking systems.

    Abstract: A security enclosure with an electronic lock, a concealed hinge door and lock wheel which operates a lock internal to the security enclosure. The electronic lock operates by a key pad into which a required security code may be entered. When the correct code is entered, a solenoid within the enclosure retracts moving a pin which allows the lock wheel to rotate. When the lock wheel is rotated, strike bolts extending into the top and bottom of the enclosure and left and right strike bars extending to the sides of the enclosure are retracted enabling the door to be pulled open. The door construction is such that there are no external hinges which may be drilled out, and the door itself is recessed so that it cannot be pried open. Attempts to turn the lock wheel when the solenoid is engaged have no effect because the wheel cannot be turned without breaking.

The rotatable actuator plate member enables all of the actuators to be moved from a single location so that a plurality of cams, etc., are not needed to move locking bolts positioned about the perimeter of the door between open and locking positions. In an additional aspect of the invention, horizontally extending actuator bars are adjustably attached to elongate locking bars having a plurality of locking bolts attached thereto, so as to enable assembly of the locking structures of the door locking mechanism without assembly, and to enable interchangeability of parts.

  • Patent number: 5632166
    Abstract: A locking mechanism for furniture unit is provided which utilizes a single component for translating rotary motion of a tumbler cylinder of a key lock into reciprocating, linear motion of a pair of opposing lock rods. The mechanism includes a base having a pair of linear guide channels which are defined by spaced sidewalls, a lock rod received in each of the linear guide channels, each of the lock rods having a radially extending projection engaging the sidewalls of one of the guide channels, a key lock, and an actuator which is attached to a drive shaft connected to the tumbler cylinder of the key lock. The actuator includes a pair of arcuate channels, each of which is at least partially defined by spaced camming surfaces which engage opposing sides of the projections on the lock rods, whereby rotation of the actuator in one direction retracts the rods to the unlocked position and rotation in the opposite direction extends the rods to the locked position.

  • Patent number: 5404737
    Abstract: A lock assembly has a main lock housing, a bolt movable in the housing between a locked position projecting from the housing and an unlocked position largely recessed in the housing and a double cylinder having an outside key-operable part rotatable by an appropriately bitted key and an inside part rotatable by the outside part and also rotatable independently of the outside part. The inside part carries an actuator movable on rotation of either part. A gear linkage between the actuator and the bolt displaces the bolt. A secondary housing is provided adjacent the lock housing and an actuator element coupled and movable with the linkage extends from the lock housing to the secondary housing. The element moves relative to the secondary housing on movement of the bolt between its positions. An electric motor on the secondary housing connected to the element is energizable for displacing same and thereby also displacing the bolt between its positions.

  • Patent number: 5245846
    Abstract: A locking mechanism for use with lightweight security doors includes a first gear and a mechanically associated second gear. A lock disposed proximate the second gear is adapted to form a releasable locking engagement with the second gear. The first gear is mechanically associated with a locking assembly which intercooperates with the door frame of the security door to produce a locking engagement therewith. The locking assembly is actuated by the rotation of the first gear. A rotation of the first gear causes a corresponding rotation of the second gear and vice versa. The second gear is mounted to be manually displaceable whereby the second gear can be displaced out of engagement with the lock and thereby become rotatable notwithstanding that the lock has been set in its locked condition.

  • Patent number: 4679415
    Abstract: A locking mechanism which includes a rack-and-pinion-type gearing arrangement positioned on the interior surface of a security cabinet door surface is disclosed. The pinion-type gear is made rotatable by a shaft affixed thereto which communicates with the exterior surface of the door. The rack portion of the gearing arrangement is fixedly mounted to a plurality of shaft-like members which are adapted to be slidably displaced along the interior surface of the door. The shaft-like members position a plurality of bolt-like members about the perimeter of the door and function to extend those bolt-like members beyond the perimeter of the door and thereby secure the door when it is in a closed position. A bolt-like locking mechanism is positioned in conjunction or proximity to the shaft-like extensions whereby the locking mechanism may be employed to preclude the further displacement of the shaft-like extensions and thereby maintain the safe in a secured, locked position.
