Abstract

A passive lock assembly is suitable for use with a door mounted to a door frame. The passive lock assembly includes a housing, a bolt, an actuator, and a stop member. The housing is mounted on the door. The bolt extends from the housing and is moveable between an extended position and a retracted position. The actuator is supported by the housing and is operably connected to the bolt. Additionally, the actuator is moveable to move the bolt between the extended position and the retracted position. The stop member is pivotably connected to the housing and pivotable between a first position and a second position. In the first position, the stop member engages an engagement surface of the actuator to obstruct movement of the actuator and prevent movement of the bolt to the retracted position, and in the second position, the stop member does not obstruct movement of the actuator.

Independent Claims | See all claims (21)

  1. 1. A passive lock assembly for use with a door mounted to a door frame and moveable between an open position and a closed position, the passive lock assembly comprising: a housing adapted to be mounted on the door, the housing including a face plate having an active bolt opening; a first bolt extending from the housing and moveable between an extended position, wherein the first bolt is adapted to engage the door frame to lock the door in the closed position, and a retracted position, wherein the first bolt is adapted to retract from the door frame to permit the door to move to the open position; an actuator supported by the housing and operably connected to the first bolt, the actuator being moveable to move the first bolt between the extended position and the retracted position, the actuator having an engagement surface; and a stop member pivotably connected to the housing and pivotable between a first position, wherein the stop member engages the engagement surface of the actuator to obstruct movement of the actuator and prevent movement of the first bolt to the retracted position, and a second position, wherein the stop member does not obstruct movement of the actuator, and wherein the stop member is repositionable from the second position to the first position when contacted by a portion of an active lock assembly extending through the active bolt opening of the face plate.
  2. 14. A passive lock assembly for use with a door mounted to a door frame and moveable between an open position and a closed position, the passive lock assembly comprising: a housing adapted to be mounted on the door, the housing including a face plate having an active bolt opening that provides a horizontal line of travel extending into the housing; a receiver adapted to be mounted on the door frame; a bolt extending from the housing and moveable between an extended position, wherein the bolt engages the receiver to lock the door in the closed position, and a retracted position, wherein the bolt retracts from the receiver to permit the door to move to the open position; an actuator supported by the housing and operably connected to the bolt, the actuator being moveable to move the bolt between the extended position and the retracted position, the actuator having an engagement surface; and a stop member supported by the housing and moveable between a first position, wherein the stop member engages the engagement surface of the actuator to obstruct movement of the actuator and prevent movement of the bolt to the retracted position, and a second position, wherein the stop member does not obstruct movement of the actuator, wherein at least a portion of the stop member is accessible through the active bolt opening and lies along the horizontal line of travel.
  3. 19. A door assembly comprising: a door frame; an active door mounted within the door frame and moveable between an open position and a closed position; a passive door mounted within the door frame in side-by-side relation with the active door and moveable between an open position and a closed position; an active lock mounted within the active door, the active lock comprising a latch bolt moveable between an extended position and a retracted position, and a first handle operably coupled to the latch bolt to move the latch bolt between the extended position and the retracted position; a receiver mounted in the door frame; and a passive lock assembly comprising: a housing mounted within the passive door, the housing having a face plate having an aperture therein; a shoot bolt extending from the housing and moveable between an extended position, wherein the shoot bolt engages the receiver to lock the passive door in the closed position, and a retracted position, where the bolt retracts from the receiver to permit the passive door to move to the open position; a retraction member supported by the housing and operably connected to the shoot bolt for moving the shoot bolt between the extended position and the retracted position; an actuator supported by the housing and operably connected to the retraction member, the actuator being moveable to move the shoot bolt between the extended position and the retracted position, the actuator having an engagement surface; a handle coupled to the actuator and adapted to be manipulated by a user to move the actuator; a first spring member coupled to the actuator to bias the actuator to a central position; a pivotable stop member pivotably connected to the housing and pivotable between a first position, wherein the stop member engages the engagement surface of the actuator to obstruct movement of the actuator and prevent movement of the shoot bolt to the retracted position and wherein the stop member is substantially normal to the engagement surface, and a second position, wherein the stop member does not obstruct movement of the actuator; and a second spring member coupled to the stop member to bias the stop member toward the second position, wherein when the active door and the passive door are in the closed positions and the latch bolt is in the extended position, the latch bolt extends into the housing and engages the stop member to move the stop member from the second position to the first position.
