    摘要: A door lock apparatus including a door lock housing, a door lock, and a keypad operatively connected to the door lock housing and to the door lock. The keypad includes a protective layer, a decorative layer, and a light source, wherein the protective layer is disposed next to the decorative layer and the decorative layer is disposed between the protective layer and the light source. The decorative layer includes a first surface having a first material located thereon and a second surface having a second material located thereon, and wherein the first material and the second material are generally aligned to provide indicia having a three-dimensional appearance with the indicia being offset from a background plane.

    摘要: A tamper resistant lock. A lock has a lock housing with housing indentation. A cylinder is rotatably housed within the housing. A locking pin is connected to the cylinder and is inserted into the housing indentation when the lock is in a locked position and the locking pin is clear of the housing indentation when the lock is in an unlocked position. An anti-tampering mechanism is positioned between the housing and the cylinder. The anti-tampering mechanism receives a user's key and also includes a relative motion hole. A key extension portion is rotatably inserted inside the anti-tampering mechanism body and includes a relative motion indentation. The key extension portion is keyed to the cylinder. A lock ball is inserted into the relative motion hole and the relative motion indention, thereby preventing relative motion between the anti-tampering mechanism body and the key extension portion. A flexible band is wrapped around the anti-tampering mechanism body and covers the lock ball and holds the lock ball in place in the relative motion hole and relative motion indentation. The flexibility of the flexible band is sufficient to permit the lock ball to leave the relative motion indentation while simultaneously retaining the lock ball in the relative motion hole if the anti-tampering mechanism body is rotated while the locking pin is inserted into the housing indentation, thereby permitting relative motion between the anti-tampering mechanism body and the key extension portion. In a preferred embodiment the tamper resistant lock is a padlock.

    摘要: The present disclosure relates to a rotating lock latch bolt and a lock having rotating lock latch bolt. In certain embodiments, rotating lock latch bolt may include a first cylindrical body and a second cylindrical body connected co-axially below the first cylindrical body. The lock may include a lock latch, a lock latch control mechanism, a rotating lock latch bolt, and a rotating lock latch bolt control mechanism. Lock latch control mechanism may be configured to drive lock latch to a first position to lock the lock, and to a second position to unlock the lock. The rotating lock latch bolt may be configured to bolt the lock latch to prevent the lock latch from moving when the lock latch is in the first position. The rotating lock latch bolt control mechanism may be configured to rotate the rotating lock latch bolt to bolt and release the lock latch.

    摘要: An electrical mechanical locking device. A lock has an outer shell with an indentation. An inner body is rotatably housed within the outer shell. A contact pin is connected to the inner body. A printed circuit board frame is rigidly connected to the inner body. A printed circuit board is attached to the printed circuit board frame. A driver arm support bracket is rigidly connected to the printed circuit board frame. A lock microprocessor is connected to the printed circuit board and electrically connected to the contact pin. The lock microprocessor is connected to a key identification code verification database. An electrical actuator is electrically connected to the lock microprocessor. A driver arm is pivotally connected to the driver arm support bracket. The electrical actuator is connected to the driver arm. A jam plate is connected to the driver arm. A jam plate return spring is connected to the jam plate and the printed circuit board frame. A locking pin is covered by the jam plate and inserted into the outer shell indentation when the electrical mechanical device is locked. When the electrical mechanical device is unlocked the locking pin is not covered by the jam plate and rises clear of the indentation. A powered key includes a key microprocessor. A battery power source is electrically connected to the key microprocessor. The key microprocessor has access to key database that includes a programmable key identification code for identifying the key. The key also includes a contact tip for insertion into the lock and for making electrical contact with the lock contact pin. In a preferred embodiment the electrical actuator is a nitinol wire.
