Abstract

A latching handleset assembly includes a handle, a trigger, and a latch driver. The handle has a handle portion and a top mounting portion that extends from an escutcheon. The top mounting portion has a top surface and a bottom that is at least partially obscured by the handle portion. The trigger includes an exterior end located along the bottom of the top mounting portion and an interior end extending into the escutcheon. The trigger is pivotable about a pivot point positioned within the escutcheon. The latch driver is movable between a neutral position and a latch actuating position in response to actuation of the trigger.

Claims (37)

1. A latching handleset assembly comprising:

a handle having a handle portion and a top mounting portion extending from an escutcheon, the top mounting portion having a top surface and a bottom with a recess at least partially obscured by the handle portion;

a trigger comprising an exterior end located along the bottom of the top mounting portion proximate the recess, the exterior end at least partially exposed relative to the top mounting portion, and an interior end extending into the escutcheon, the trigger being pivotable about a pivot point positioned within the escutcheon, wherein the exterior end is positioned opposite of the interior end relative to the pivot point;

a housing assembly including a bracket biased into a neutral position by a spring, the interior end of the trigger engaged with the bracket; and

a latch driver movable between a neutral position and a latch actuating position in response to actuation of the trigger.

2. The latching handleset assembly of claim 1 , wherein the trigger is pivotable between a neutral position and an actuated position, such that when the trigger is pivoted from the neutral position to the actuated position, at least a portion of the exterior end is movable from an exposed position to a recessed position within the top mounting portion.

3. The latching handleset assembly of claim 1 ,

wherein the bracket is movable from the neutral position to an actuated position in response to actuation of the trigger, the bracket including a rack; and

wherein the latch driver includes a geared end operatively engaged with the rack to move the latch driver between the neutral position and the latch actuating position.

4. The latching handleset assembly of claim 3 , further comprising a latch assembly including a bolt movable between an extended position and a retracted position in response to actuation of the trigger.

5. The latching handleset assembly of claim 4 , wherein a direction of movement of the bracket between the neutral position and the actuated position is perpendicular to a direction of movement of the bolt between the extended position and the retracted position.

6. The latching handleset assembly of claim 3 , wherein the bracket resides at least in part within the escutcheon.

7. The latching handleset assembly of claim 3 , wherein movement of the bracket from the neutral position to the actuated position compresses the spring.

8. The latching handleset assembly of claim 3 , wherein the spring biases the bracket toward the neutral position such that, upon release of the trigger, the bracket returns to the neutral position and the trigger moves from an actuated position to a neutral position.

9. The latching handleset assembly of claim 1 , wherein the handle further includes a bottom mounting portion extending from the handle portion to a secondary escutcheon.

10. The latching handleset assembly of claim 1 , further comprising a locking cylinder extending through the escutcheon.

11. A method for operating a latching handleset assembly having a top mounting portion, a handle portion, and a trigger at least partially obscured by the handle portion, the method comprising:

actuating an exterior end of the trigger, causing the trigger to pivot about a pivot point positioned within an escutcheon, the exterior end at least partially exposed relative to the top mounting portion;

wherein:

pivoting the trigger causes an interior end of the trigger located within the escutcheon to engage a bracket within a housing assembly biased into a neutral position by a spring so as to actuate a latch driver, the exterior end is positioned opposite of the interior end relative to the pivot point; and

actuating the latch driver causes the latch driver to move between a neutral position and a latch actuating position.

12. The method of claim 11 , wherein when the trigger is pivoted from a neutral position to an actuated position, at least a portion of the exterior end of the trigger is movable from an exposed position to a recessed position within the top mounting portion.

13. The method of claim 11 , wherein in response to actuation of the trigger, the bracket biased by the spring moves from the neutral position to an actuated position, and the latch driver including a geared end operatively engaged with a rack causes the latch driver to move between the neutral position and the latch actuating position.

14. The method of claim 13 , wherein in response to actuation of the trigger, a latch bolt is movable between an extended position and a retracted position.

15. The method of claim 14 , wherein a direction of movement of the bracket between the neutral position and the actuated position is perpendicular to a direction of movement of the latch bolt between the extended position and the retracted position.

16. The method of claim 13 , wherein when the bracket moves from the neutral position to the actuated position, the spring is compressed.

17. A latching handleset assembly comprising:

a handle having a vertical handle portion and a top mounting portion extending in a horizontal direction from an escutcheon mounted on a door, the top mounting portion having a top surface and a bottom with a recess at least partially obscured by the handle portion;

a trigger having an exterior end located along the bottom of the top mounting portion proximate the recess, the exterior end at least partially exposed relative to the top mounting portion, and an interior end extending into the escutcheon, the trigger being pivotable about a pivot point positioned within the escutcheon, wherein the exterior end is positioned opposite of the interior end relative to the pivot point;

a housing assembly including a bracket biased into a neutral position by a spring, the interior end of the trigger engaged with the bracket;

a latch driver movable between a neutral position and a latch actuating position in response to actuation of the trigger; and

a latch assembly including a latch bolt movable between an extended position and a retracted position in response to actuation of the trigger.

18. The latching handleset assembly of claim 17 , wherein the trigger is pivotable between a neutral position and an actuated position, such that when the trigger is pivoted from the neutral position to the actuated position, at least a portion of the exterior end is movable from an exposed position to a recessed position within the top mounting portion.

19. The latching handleset assembly of claim 17 ,

wherein the bracket is movable from the neutral position to an actuated position in response to actuation of the trigger, the bracket including a rack; and

wherein the latch driver includes a geared end operatively engaged with the rack to move the latch driver between the neutral position and the latch actuating position.

20. The latching handleset assembly of claim 19 , wherein a direction of movement of the bracket between the neutral position and the actuated position is perpendicular to a direction of movement of the latch bolt between the extended position and the retracted position.
