Masonite International has been granted a patent for a multipoint lock assembly for swinging doors. The assembly includes a mortise housing installed in the door panel, with latch and lock operating mechanisms. The latch mechanism can be transitioned between left- and right-hand orientations, and a latch retainer secures it in the desired orientation. The lock mechanism extends a deadbolt and shoot bolts from the door edges, which are also secured against forced back-drive.

A lock mechanism for a swinging door panel
A recently granted patent (Publication Number: US11746565B2) describes a lock mechanism for doors that can be easily reconfigured to accommodate both left-handed and right-handed swing orientations. The lock mechanism includes a latch operating mechanism that is installed within the door panel and a latch with an inner and outer portion. The latch can be retracted from an extended position to a retracted position, and it can be transitioned between left-hand and right-hand swing orientations by rotating it 180 degrees about its longitudinal axis. A latch retainer is also included, which rotates with the latch and selectively secures it in either swing orientation.
The patent claims that the latch can transition between swing orientations without disassembly or removal of the lock mechanism from the door panel. This allows for easy reconfiguration of the lock mechanism to accommodate different door swing orientations.
The latch includes an adjustment slot that can be engaged to rotate the latch between swing orientations. The latch retainer consists of a base and a first retainer spring that biases a retainer spring tab outwardly. The retainer spring tab can be nested in a first or second notch to secure the latch in the left-hand or right-hand swing orientation, respectively.
The lock mechanism is designed to be installed within a mortise box in the door panel, with a face plate securing the latch retainer in place. The latch retainer rotates when the latch is rotated, and the retainer spring tab engages walls defining the respective notch to secure the latch in the desired swing orientation.
The patent also describes a door panel assembly that incorporates the lock mechanism. The assembly includes a door panel with a hinged edge and a lock edge, and the lock mechanism is installed between the first and second faces of the door panel adjacent to the lock edge. The assembly can be configured as a left-handed or right-handed swing door by securing the hinged edge to a door frame accordingly.
Additionally, the patent describes a deadbolt operating mechanism that works in concert with the lock mechanism to transition the deadbolt, first auxiliary retainer, and second auxiliary retainer between extended and retracted positions. The deadbolt operating mechanism includes a four bar linkage that prevents back driving of the components in the extended position.
Overall, this patented lock mechanism offers a convenient solution for reconfiguring door swing orientations without the need for disassembly or removal of the lock mechanism.
