Transverse concealed latch system

A system, comprising:

• a latch mechanism configured for mounting to a door, the latch mechanism comprising:
• a latchbolt having a latching position and an unlatching position, the latchbolt comprising a channel, wherein the latchbolt is pivotable about a first axis;
• and
• a blocking member operable to selectively retain the latch in the latching position, wherein the blocking member is pivotable about a second axis transverse to the first axis;
• and
• a strike configured for mounting to a doorframe adjacent the door, the strike comprising a projection sized and shaped to be received in the channel;
• wherein the system has an installed state in which the latch mechanism is mounted to the door, and the strike is mounted to the doorframe;
• wherein, with the system in the installed state, the door in a closed position, the latchbolt in the latching position, and the blocking member in a blocking position, the projection is received in the channel, and the system prevents opening of the door;
• and
• wherein, with the system in the installed state, the door in a closed position, the latchbolt in the latching position, and the blocking member in an unblocking position, opening of the door is permitted, and opening of the door causes the strike to move the latchbolt to the unlatching position.

A method of operating a closure assembly comprising a latch mechanism mounted to a door and a strike mounted to a doorframe, the method comprising:

• with the door in an open position and a latchbolt of the latch mechanism in an unlatching position, engaging the strike with the latchbolt in response to movement of the door to a closed position, thereby causing the strike to pivot the latchbolt about a first axis to a latching position;
• and
• with the door in the closed position and the latchbolt in the latching position, pivoting a blocking member of the latch mechanism about a second axis from an unblocking position to a blocking position, thereby retaining the latchbolt in the latching position and causing the strike to prevent opening of the door;
• and
• wherein the first axis and the second axis are transverse to one another.
