Abstract

A door latch assembly having a latching mechanism and a substantially flush-mounted actuator. The actuator may raise and lower a latch within the latching mechanism to engage and disengage the strike plate of an adjacent door jam. Similar to the actuator, a key cylinder may be substantially flush-mounted on an opposite side of the door. The key cylinder may lock or unlock the latch assembly.

Claims

1. A latching assembly for use with a door having a frame, a front edge, and two sides, the latching assembly comprising:

a pocket substantially flush-mounted in one side of the door;

an actuator substantially disposed within the pocket;

a latch mechanism disposed within the frame; and

a latch disposed within the latch mechanism;

wherein the latch assembly is responsive to the operation of the actuator such that the latch may extend from the front edge of the door and engage an adjacent object in a locking position.

2. The latching assembly of claim 1, wherein the latch assembly is responsive to the operation of the actuator such that the latch assembly is substantially enclosed within the front edge of the door in an unlocked position.

3. The latching assembly of claim 1, further comprising:

a key cylinder having a surface and a body;

the key cylinder body disposed within the frame substantially opposite of the knob and operable with the knob; and

the key cylinder surface being substantially flush with the frame;

wherein, the key cylinder is capable of transitioning the latch to a locking position.

4. The latching assembly of claim 1 further comprising a hand pull substantially flush with the side portion of the door.

5. A latching assembly for use with a sliding door, the sliding door having a frame, a front edge, and two sides, the latching assembly comprising:

a pocket having a body and a rim;

a knob;

a lever;

a latch mechanism having a hook;

the pocket being substantially recessed within the frame such that the rim of the pocket is substantially flush with one side of the door;

the actuator disposed within the pocket;

the lever disposed substantially within the frame and operable in response to the knob; and

a latching mechanism disposed substantially within the frame and operable in response to the lever;

wherein the knob is capable of actuating the lever which in turn actuates the latch mechanism such that the hook extrudes from the front edge of the door into a locking position.

6. The latching assembly of claim 5, wherein the knob is capable of actuating the lever which in turn actuates the latching mechanism such that the hook is substantially retracted into the body of the door in an unlocked position.

7. The latching assembly of claim 5, further comprising:

a key cylinder having a surface and a body;

the key cylinder body disposed within the frame on the opposite side of the door from the knob and operable with the knob; and

the key cylinder surface being substantially flush with the frame;

wherein, the key cylinder is capable of transitioning the hook to a locking position.

8. The latching assembly of claim 5 further including hand pulls that are substantially flush with the side portion of the frame.

9. A latching assembly for use with the frame of a sliding door, the latching assembly comprising:

a body having a front surface, a side surface, and an interior space;

a pocket disposed on the side surface and extending into the interior volume;

a knob dispose substantially within the pocket;

a hand pull disposed on the sliding door for moving the sliding door;

a hook assembly disposed within the interior surface and responsive to the operation of the knob such that the hook assembly is transitional between a locking position where the hook assembly is partially extruded from the front surface of the body and an unlocked position where the hook assembly is mostly enclosed within the body.

10. A latching assembly for use with the frame of a sliding door, the frame having a body, a front portion, and a side portion, the latching assembly comprising:

a recess within the side portion of the frame;

a knob substantially disposed within the recess; and

a hook assembly disposed within the body of the frame;

wherein the hook assembly is responsive to the operation of the knob such that the hook assembly is transitioned to a locking position.

11. The latching assembly of claim 10, further comprising:

a key cylinder having a surface and a body;

the key cylinder body disposed within the frame substantially opposite of the knob and operable with the knob; and

the key cylinder surface being substantially flush with the frame;

wherein, the key cylinder is capable of transitioning the hook to a locking position.

12. The latching assembly of claim 10 further including hand pulls that are substantially flush with the sides of the door.

13. A latching assembly for use with a sliding door having a body, a front portion, and sides, the latching assembly comprising:

a pocket having a body and a rim;

a knob;

a lever;

a hook assembly having a body and a hook;

the body of the pocket being substantially recessed within the frame such that the rim of the pocket is substantially flush with the side portion of the frame;

the knob disposed within the pocket;

the lever dispose substantially within the body of the frame and operable in response to the knob; and

the hook assembly disposed within the body of the frame and operable in response to the lever to the lever;

wherein the knob is capable of actuating the lever which in turn actuates the hook assembly such that the hook transitions to a locking position.

14. The latching assembly of claim 13 further including hand pulls that are substantially flush with the sides of the door.

15. A latching apparatus for use with a door having a frame, a front edge, and two sides, the latching assembly comprising:

a pocket substantially flush-mounted in one side of the door;

an actuator substantially disposed within the pocket;

a latch mechanism disposed within the frame;

a hand pull on each side of the frame and each handpull being offset from the other; and

a latch disposed within the latch mechanism;

wherein the latch assembly is responsive to the operation of the actuator such that the latch may extend from the front edge of the door and engage an adjacent object in a locking position.

16. A latching apparatus for use with a door having a frame, a front edge, and two sides, the latching assembly comprising:

a pocket substantially flush-mounted in one side of the door;

an actuator substantially disposed within the pocket;

a latch mechanism disposed within the frame and the latch mechanism disposed a distance from the actuator; and

a latch disposed within the latch mechanism;

wherein the latch assembly is responsive to the operation of the actuator such that the latch may extend from the front edge of the door and engage an adjacent object in a locking position.

17. A latching apparatus for use with a door having a frame, a front edge, and two sides, the latching assembly comprising:

a pocket substantially flush-mounted in one side of the door;

an actuator substantially disposed within the pocket;

a shaft flipper, where the actuator is disposed a distance from the shaft flipper;

a latch mechanism disposed within the frame; and

a latch disposed within the latch mechanism;

wherein the latch assembly is responsive to the operation of the actuator, which is responsive to operation of the shaft flipper, such that the latch may extend from the front edge of the door and engage an adjacent object in a locking position.

18. A latching structure for use with a door having a frame, the latching structure comprising;

a primary latch assembly integrated with the frame;

a secondary latch assembly integrated with the frame; and

a linkage;

wherein the linkage operably connects the primary and secondary latch assemblies such that the latch assemblies operate substantially in unison.
