Multi-point sliding door lock

A multi-point sliding door lock comprising:

• a lock assembly including:
• a lock housing elongated along a longitudinal axis, the lock housing having a locking face and a rear face, the locking face and the rear face opposite one another relative to a transverse axis that is orthogonal to the longitudinal axis;
• a pair of latch elements pivotally coupled to the lock housing, each of the pair of latch elements configured to move between an extended position relative to the locking face and a retracted position;
• and
• a slide plate disposed within the lock housing and slidable along the longitudinal axis, the slide plate engaged with the pair of latch elements such that sliding movement of the slide plate moves each of the pair of latch elements between the extended position and the retracted position, wherein the slide plate includes a plurality of transverse grooves spaced along the longitudinal axis and open relative to the rear face;
• and
• a cartridge assembly including:
• a cartridge housing insertable at least partially into the lock housing from the rear face in a direction parallel to the transverse axis, the lock assembly configured to receive the cartridge assembly in a plurality of different positions corresponding to the plurality of transverse grooves;
• a hub rotatably mounted at least partially within the cartridge housing and defining an opening configured to receive a torque blade, the hub includes at least one radially extending arm;
• and
• a pin supported by the at least one radially extending arm and the cartridge housing, wherein the pin engages with one of the plurality of transverse grooves when the cartridge assembly is received by the lock assembly such that rotation of the hub drives the sliding movement of the slide plate.

A method of installing a multi-point sliding door lock comprising:

• providing the multi-point sliding door lock that includes a lock assembly with a lock housing elongated along a longitudinal axis, the lock housing having a locking face and a rear face, the locking face and the rear face opposite one another relative to a transverse axis that is orthogonal to the longitudinal axis, a pair of latch elements pivotally coupled to the lock housing, each of the pair of latch elements configured to move between an extended position relative to the locking face and a retracted position, and a slide plate disposed within the lock housing and slidable along the longitudinal axis, the slide plate engaged with the pair of latch elements such that sliding movement of the slide plate moves each of the pair of latch elements between the extended position and the retracted position, the multi-point sliding door lock also includes a cartridge assembly with a cartridge housing and a hub rotatably mounted at least partially within the cartridge housing and defining an opening configured to receive a torque blade, wherein the hub engages with the slide plate when the cartridge assembly is received by the lock assembly such that rotation of the hub drives the sliding movement of the slide plate, and wherein the slide plate defines a plurality of hub mounts spaced along the longitudinal axis and facing towards the rear face of the lock housing, each of the plurality of hub mounts configured to engage with the hub of the cartridge assembly;
• inserting the cartridge housing at least partially into the lock housing at one of the plurality of hub mounts, wherein the cartridge housing is inserted from the rear face of the lock housing and in a direction parallel to the transverse axis;
• setting a backset distance of the opening of the hub relative to the locking face of the lock housing by selectively positioning the cartridge housing along the transverse axis and relative to the lock housing;
• and
• mounting the lock assembly with the cartridge assembly attached thereto to a sliding door.
