• (ii) when the disconnect member portion is in its disconnecting position, to provide no driving connection between the handle and bolt structures;
• (e) key-control means connected to one of the structures and having a locking member movable between locked and unlocked positions, the key-control means being operable:
• (i) when the locking member is in its unlocked position, to position the disconnect member portion in its connecting position;
• and,
• (ii) when the locking member is in its locked position to position the disconnect member portion in its disconnecting position;
• (f) the disconnect means additionally including guide means mounting at least a segment of the disconnect member for movement along a fourth path of travel within the passage in response to movement of the handle structure between its normal and operating positions such movement along the fourth path of travel being in conjunction with movement of the bolt structure along the first path of travel when the disconnect member portion is in its connecting position, and being relative to the bolt structure when the disconnect member portion is in its disconnecting position;
• and,
• (g) the first, second and fourth paths of travel extending within the passage substantially parallel to each other and lying in a substantially common plane, and the third path of travel extending substantially laterally within the passage with respect to at least one of the first and second paths of travel.

A door lock comprising:

• (a) a body structure defining an elongate bolt-mounting passage thereon;
• (b) a bolt structure positioned at least partly in the passage for movement along a first path of travel between latching and unlatching positions;
• (c) a handle structure connected to the body structure for movement between normal and operating positions;
• (d) an operating formation connected to the handle structure for movement within the passage in response to movement of the handle structure between its normal and operating positions, the movement of the operating formation following a second path of travel;
• (e) disconnect means interposed between the operating formation and the bolt structure, and including a disconnect member positioned at least partly within the passage and being movable between connecting and disconnecting positions, the disconnect means being operable:
• (i) when the disconnect member is in its connecting position to intersect the first and second paths of travel to drivingly connect the handle and bolt structures such that, when the handle structure is moved to its operating position, the bolt structure is caused to move to its unlatching position;
• and,
• (ii) when the disconnect member is in its disconnecting position, to provide no driving connection between the handle and bolt structures;
• (f) key-control means connected to one of the structures and including a locking member movable between locked and unlocked positions, the key-control means being operable:
• (i) when the locking member is in its unlocked position, to position the disconnect member in its connecting position;
• and,
• (ii) when the locking member is in its locked position, to position the disconnect member in its disconnecting position;
• and,
• (g) the disconnect member being movable in two distinctly different modes within the passage, one mode being in response to movement of the locking member and the other mode being in response to movement of the handle structure, the movement of the disconnect member in said other mode being in conjunction with movement of the bolt structure along the first path of travel when the disconnect member is in its connecting position, and being relative to the bolt structure when the disconnect member is in its disconnecting position.

A flush-mountable door lock, comprising:

• (a) a body structure having side and back walls which cooperate to define a forwardly-facing recess, having an opening formed through the back wall, and having structure defining a bolt-mounting passage;
• (b) an elongate bolt structure slidably supported on the body structure at a location behind a portion of the back wall, the bolt structure being movable within the passage along a path of movement between a projected position wherein the bolt structure is extended with respect to the body structure, and a retracted position wherein the bolt structure is retracted with respect to the body structure, the bolt structure having a receiving formation communicating with the back wall opening;
• (c) a handle structure mounted on the body structure and being movable between a nested position wherein the handle structure is nested within the recess, and an operating position;
• (d) key-control means carried by the body structure and a locking member movable between locked and unlocked positions;
• (e) connecting means carried by the handle structure and being movable therewith, the connecting means extending through the back wall opening, into the passage and into the receiving formation of the bolt structure;
• (f) disconnect linkage means positioned at least partly in the passage, having a first portion extending into the receiving formation for engaging the connecting means, and having a second portion extending longitudinally of the bolt structure toward the key-control means, at least a part of the disconnect linkage means being movable transversely with respect to the path of movement of the bolt structure between a connecting position wherein it is operable to drivingly interconnect the handle and bolt structures such that when the handle structure is moved out of its nested position the bolt structure is caused to retract, and a disconnecting position wherein no driving connection is provided between the handle and bolt structures;
• (g) the disconnect linkage means being movable longitudinally with respect to the path of movement of the bolt structure:
• (i) in conjunction with movement of the bolt structure when the first portion is in its connecting position and the handle structure is moved out of its nested position;
• and,
• (ii) relative to the bolt structure when the first portion is in its disconnecting position and the handle structure is moved out of its nested position;
• and,
• (h) the locking member being engageable with the second portion of the disconnect linkage means for moving the disconnect linkage means to its connecting position when the locking member is moved to its unlocked position, and for moving the disconnect linkage means to its disconnecting position when the locking member is moved to its locked position.
