  • Patent number: 11044826
    Abstract: The present disclosure relates to a cover-securing mechanism for a transmitter housing closed by a screwed-on cover. The cover-securing mechanism includes a securement pin with a screw arranged at a first end region of the securement pin. A passageway, which is embodied to accommodate the securement pin, is integrated in the cover. A groove includes a circularly shaped section and is introduced into a cover facing region of the transmitter housing. The securement pin is securable at a transmitter housing far end of the cover in the passageway such that in a secured state a second end region of the securement pin protrudes inwardly into the groove and, as such, a twisting of the cover screwed onto the transmitter housing is constrained relative to the transmitter housing.

  • Patent number: 10787844
    Abstract: Methods and apparatuses can be configured to facilitate the guarding of doors to replace the need for a lock or to supplement a lock to help bar access to a room via a door. Embodiments of the apparatus can be configured as a door guard. The door guard can be mountable adjacent a door and be configured for attachment to a door via a mounting device attached to a rear of a door so that a door guard can be positioned quickly in the event of an unanticipated emergency situation. The door guard may block opening of a door outward out of a room and into an adjoining hallway of a building by preventing extending to opposite sides of a door frame or walls defining the door opening to prevent an attacker from pulling the door open.

  • Patent number: 9493965
    Abstract: A door lock assembly operates a deadbolt between unlocked and locked positions. It includes an actuator, a ring, and a spring member. The actuator includes an integral arm, that extends inwardly, to the center of the ring, and the arm has a cam provided upon the center axis, and receives the torque blade from center key cylinder. In the preferred embodiment, when the ring is turned in a clockwise direction, it locks the deadbolt of the latch bolt assembly, by shifting it to a locking position, and all of this can be achieved because the key cylinder is on a center axis, and the axis of the latch bolt assembly and deadbolt intersects that same center axis in their operation.

    Abstract: A door lock secures a door when closed within a doorframe. The lock includes a bolt guide, a bolt, a bolt actuator, and a bolt receiver. The bolt includes a first portion that is adjacent to a proximal end and a second portion that is adjacent a distal end of the bolt. The actuator moves the bolt along the bolt guide between a locked position and an unlocked position. The second portion extends beyond the guide when in the locked position and is received by the receiver. The bolt deforms within the receiver and thereby predominantly absorbs energy from an intrusion load. A maximum deformation of the bolt prior to failure of the lock from the intrusion load is at least 4%, 25%, or 120% of a thickness of the bolt. A maximum deformation of the bolt prior to failure of the lock may be at least 40%, 55%, or 72% of a maximum overall deflection of the lock. The receiver may include a deformation guide that guides deformation of the bolt.

  • Patent number: 7530245
    Abstract: A door lock includes outer assemblies, latch assemblies and inner assemblies. The inner assemblies has a turning switch, fixing bolts, an interior rose and a detent device that includes an inner plate, a stop plate, a stop seat, a rotating spring, a retaining spring and a sprag. By pressing down the stop plate as the latch bolt is in a casing, a protruding block of the stop seat is engaged with a protruding member of the stop plate. The spindle can not rotate backward and maintains in an unlocked state. After the stop plate is pressed upward, the turning switch returns to a locked state and the latch bolt extends out of the casing. Therefore, the detent device can keep the latch bolt in the casing and keep the lock in the unlocked state.

  • Patent number: 7377076
    Abstract: A handle-latch assembly mounted on a horizontal sliding door and coupled to a vertically movable latch bolt which protrudes outwardly from a top or bottom door edge, and which enables the inside and outside handles of the door to be respectively used for moving the door in closing and opening directions. The door has a manual lock actuator on the inside of the door, and an optional key-lock actuator on the outside of the door, whereby latching the door in the closed position requires a deliberate manual manipulation of either the inner lock actuator or the outer key actuator. The assembly permits sequential unlocking and opening of the door from the inside by application of a single horizontally-directed force to the inner handle. The handle-latch mechanism includes cooperating linkages, and the linkages are automatically reset into an unlocked position whenever the locked door is opened from the inside.

  • Patent number: 7213426
    Abstract: A method and apparatus for providing a storm door mortise lock that prevents lockout with a lock body having opposed side plates and a cam in between the side plates, the cam being in operative interaction with a dead bolt assembly. The mortise lock body also may include one or more stops within the deadbolt assembly to limit the rotation of the cam and prevent a lockout situation. A thumb turn button and key cylinder are secured to opposite escutcheon plates. A spindle traverses from the key cylinder through the cam through hole and terminates in the mounting slot of the thumb turn button. Rotation of either the thumb turn button or the key cylinder turns the spindle and actuates the cam that actuates the dead bolt assembly.

  • Patent number: 7207199
    Abstract: A deadbolt mechanism including a lock out mechanism that functions to disable the operation of the deadbolt from at least one side of the deadbolt mechanism. The deadbolt mechanism includes a deadbolt, key cylinder, housing, turn knob and a shaft that connects the key cylinder and turn knob. To place the deadbolt mechanism in lock out mode, the turn knob is moved to the locked positioned and then pulled outward away from the door. By pulling the knob outward, the shaft engages a portion of the housing which prevents rotation of the shaft and thereby prevents movement of the deadbolt from the locked position.

  • Patent number: 7000440
    Abstract: A plurality of separately keyed padlocks, ranging in number from 7 to 150 or more, are securely held within a circular assembly that is rotated for selection of a specific padlock. This assembly of locks can be placed at a level for easy reach from a car window. Visible imprinted numbers provide a quick way for authorized members of a group to locate the padlock which a specific key will open. When opened and the padlock is turned opposite a slotted bar, moving the bar actuates a separately installed automatic gate-opener for access to an area. Alternatively, the system can be adapted for use manually by authorized personnel to lock or unlock a gate, door, or secured equipment. No padlock can be removed from the assembly except for periodic changing of a lock when an individual leaves the group and thus is no longer permitted to enter the closed area.
