Recessed lock actuating device for sliding doors

1. A lock assembly comprising:

an interior lock actuator assembly, including:

an interior escutcheon presenting a substantially planar outer surface and including a first handle portion recessed relative to the outer surface, and a first control;

a first rotatable drive disk;

a second rotatable drive disk; and

slide arm operably coupled with the first drive disk, the second drive disk, and the first control;

an exterior lock actuator assembly comprising an exterior escutcheon presenting a substantially planar outer surface and including a second handle portion recessed relative to the outer surface and a second control, the second control operably coupled with the second drive disk; and

a lock mechanism comprising a housing and at least one lock element, the at least one lock element selectively shiftable between an unlocked position in which the at least one lock element is contained in the housing and a locked position in which the at least one lock element extends from the housing, wherein the first drive disk is operably connected with the at least one lock element so as to drive shifting of the at least one lock element between the unlocked position and the locked position when the first drive disk is rotated, and wherein the first control and the second control are selectively operable to rotate the first drive disk.

2. The lock assembly of claim 1 , wherein the first control is a thumb slide.

3. The lock assembly of claim 2 , wherein the thumb slide is coupled to the slide arm so as to vertically shift the slide arm, and the slide arm is coupled to the first drive disk such that vertical shifting of the slide arm rotates the first drive disk.

4. The lock assembly of claim 1 , wherein the second control is a key cylinder.

5. The lock assembly of claim 4 , wherein the key cylinder is operably coupled to the second drive disk.

6. The lock assembly of claim 1 , wherein the at least one lock element is a hook.

7. A sliding door assembly, comprising;

a door panel slidably mounted in a frame, the frame including a jamb; and

a lock assembly in the door panel, the lock assembly comprising:

an interior lock actuator assembly, including:

an interior escutcheon presenting a substantially planar outer surface and including a first handle portion recessed relative to the outer surface, and a first control, an outer surface of the interior escutcheon being substantially flush with an inwardly facing surface of the door panel;

a first rotatable drive disk;

a second rotatable drive disk; and

a slide arm operably coupled with the first drive disk, the second drive disk, the first control;

an exterior lock actuator assembly comprising an exterior escutcheon presenting a substantially planar outer surface and including a second handle portion recessed relative to the outer surface and a second control, an outer surface of the exterior escutcheon being substantially flush with an outwardly facing surface of the door panel, the second control operably coupled with the second drive disk; and

a lock mechanism comprising a housing and at least one lock element, the at least one lock element selectively shiftable between an unlocked position in which the at least one lock element is contained in the housing and a locked position in which the at least one lock element extends from the housing to engage a keeper in the jamb, wherein the first drive disk is operably connected with the at least one lock element so as to drive shifting of the at least one lock element between the unlocked position and the locked position when the first drive disk is rotated, and wherein the first control and the second control are selectively operable to rotate the first drive disk.

8. The sliding, door assembly of claim 7 , wherein the first control is a thumb slide.

9. The sliding door assembly of claim 8 , wherein the thumb slide is coupled to the slide arm so as to vertically shift the slide arm, and the slide arm is coupled to the first drive disk such that vertical shifting of the slide arm rotates the first drive disk.

10. The sliding door assembly of claim 7 , wherein the second control is a key cylinder.

11. The sliding door assembly of claim 10 , wherein the key cylinder is operably coupled to the second drive disk.

12. The sliding door assembly of claim 7 , wherein the at least one lock element is a hook.

13. A lock actuator assembly comprising:

an interior lock actuator assembly, including:

an interior escutcheon presenting a substantially planar outer surface and including a first handle portion recessed relative to the outer surface and a control;

at least one rotatable drive disk; and

a vertically slidable arm operably couple with the at least one drive disk so as to rotate the at least one drive disk when the arm is shifted vertically with the control;

an exterior lock actuator assembly comprising an exterior escutcheon presenting a substantially planar outer surface and including a second handle portion recessed relative to the outer surface; and

wherein the at least one rotatable drive disk is adapted to couple with a lock assembly so as to shift the lock assembly between a locked position and an unlocked position when the at least one rotatable drive disk rotates, the lock actuator assembly further comprising second rotatable drive disk operably coupled to the arm such that rotation of the second drive disk vertically shifts the arm.

14. The lock actuator assembly of claim 13 , wherein the control is a thumb slide.

15. The lock actuator assembly of claim 13 , wherein the exterior lock actuator assembly comprises a second control rotatably coupled to the second drive disk.

16. The lock actuator assembly of claim 15 , wherein the second control is a key cylinder.
