A lock mechanism is received in a mortise of the door and having a handle actuatable to displace at least one driver in translation. A depth adjustment adaptor comprises a interface connected to the elongated member, with or without a joint with at least one degree of freedom connecting the interface to the driver to adjust a depth of the interface relative to the driver and to a lateral surface of the door to actuate the axial translation of the elongated member by movement of the driver. ## Claims ### Claim 1 A lock system for a door comprising: at least one elongated member adapted to axially and vertically translate in the door so as to be moved in and out of engagement with a lock catch of a door frame;

the lock system comprising: at least one elongated member received in the at least one channel of the door and axially and vertically translatable therein to be moved beyond the end surface of the door and in and out of engagement with a lock catch of a door frame; a lock mechanism received in the mortise of the door and having a handle actuatable to displace at least one driver such that the at least one driver is movable in translation; and a depth adjustment adaptor for said at least one elongated member, the depth adjustment adaptor comprising an interface releasably connected to the at least one elongated member, and a joint with at least one degree of freedom, the joint being connected to the interface and allowing movement of the interface in the direction in which the depth of the door extends to adjust a position of the interface relative to the at least one driver and to the lateral surface of the door, the position of the interface is adjusted by movement of a portion of the interface relative to the at least one driver in the at least one degree of freedom, the depth adjustment adaptor connecting the at least one driver to the at least one elongated member such that actuation of the handle displaces the at least one driver which in turn causes the axial and vertical translation of the at least one elongated member in the channel, wherein the interface includes a carriage with a cavity for receiving a free end of the at least one elongated member, a fastener being in screwing engagement with the carriage, a tightening of the fastener blocking movement of the carriage via the joint. ### Claim 10 (depends on 9) The assembly according to claim 9, wherein the door comprises an astragal, the mortise being defined in the astragal and the door. ### Claim 11 (depends on 9) The assembly according to claim 9, wherein the at least one degree of freedom of joint is a translation in the direction in which the depth of the door extends and that is perpendicular to the at least one channel, wherein the direction in which the depth of the door extends is perpendicular to the axial and vertical translation of the at least one elongated member. ### Claim 12 (depends on 9) The assembly according to claim 9, wherein the joint comprises a scale with indicia indicating a value related to a depth of the at least one elongated member relative to the lateral surface of the door. ### Claim 13 (depends on 9) The assembly according to claim 9, wherein the carriage has an abutment slidingly moving within a slot on the at least one driver to form the joint. ### Claim 14 (depends on 9) The assembly according to claim 9, wherein the carriage comprises at least one set screw releasably pressed against the free end of the at least one elongated member in the carriage, a tool end of the at least one set screw being oriented toward the lateral surface of the door. ### Claim 15 (depends on 14) The assembly according to claim 14, wherein the lock mechanism has a faceplate, with a hole being defined in the faceplate to access the at least one set screw. ### Claim 16 (depends on 9) The assembly according to claim 9, wherein the at least one channel includes two channels the at least one driver includes two drivers, and the at least one elongated member includes two elongated members concurrently moving in opposite directions as a result of actuation from the lock mechanism, wherein the depth adjustment adaptor corresponding to each elongated member is between each elongated member and a corresponding one of the drivers. ### Claim 17 A lock system for a door comprising: at least one elongated member adapted to axially and vertically translate in the door so as to be moved in and out of engagement into a lock catch of a door frame;
