Abstract

A latch assembly includes a bolt selectively moveable between an extended position and a retracted position. A cam blocker is included and positionable in different configurations. In one configuration, the cam blocker allows the bolt to move towards the retracted position with actuation of a handle in two different rotational directions. In another configuration, the cam blocker allows the bolt to move towards the retracted position with actuation of the handle in only one rotational direction. The latch assembly is also adjustable between at least two different backset distances.

First claim

What is claimed:

1 . A latch assembly comprising:
a housing having a first end and an opposite second end, the first end and the second end defining a longitudinal axis, the housing also having a first horizontal sidewall and an opposite second horizontal sidewall; a bolt slidably mounted at least partially within the housing at the first end, the bolt selectively moveable between at least an extended position and a retracted position relative to the first end of the housing; a cam rotatably mounted at least partially within the housing proximate the second end, the cam selectively rotatable around a rotation axis, the rotation axis substantially orthogonal to the longitudinal axis and substantially parallel to the first and second horizontal sidewalls of the housing, wherein the cam includes at least one radial projection; a slide arm assembly coupling the bolt with the cam such that rotation of the cam around the rotation axis drives movement of the bolt along the longitudinal axis; and a cam blocker mounted to the housing and configured to selectively engage with the at least one radial projection of the cam, the cam blocker positionable in at least a first position, whereby the cam is freely rotatably in both directions around the rotation axis and towards both the first and second horizontal sidewalls of the housing, and a second position, whereby the cam blocker selectively engages with the at least one radial projection so as to block rotation of the cam around the rotation axis relative to the first horizontal sidewall of the housing.

2 . The latch assembly of claim 1 , wherein the cam blocker is positionable in a third position, wherein in the third position the cam blocker selectively engages with the at least one radial projection so as to block rotation of the cam around the rotation axis relative to the second horizontal sidewall of the housing.

3 . The latch assembly of claim 2 , wherein the first position of the cam blocker is located between the second and third positions of the cam blocker.

4 . The latch assembly of claim 1 , wherein the cam blocker includes a pin substantially parallel to the rotation axis and slidably mounted to the housing.

5 . The latch assembly of claim 4 , wherein the housing defines at least one slot configured to receive at least a portion of the pin, the at least one slot being substantially C-shaped.

6 . The latch assembly of claim 4 , wherein the cam blocker further includes a biasing block biasing the pin towards the cam along the longitudinal axis.

7 . The latch assembly of claim 1 , wherein the latch assembly has an adjustable backset between at least two different backset positions.

8 . The latch assembly of claim 1 , further comprising a sleeve rotatably mounted at the first end of the housing, wherein rotation of the sleeve in a first direction around the longitudinal axis extends the sleeve and at least a portion of the bolt relative to the first end of the housing, and rotation of the sleeve in an opposite second direction around the longitudinal axis retracts the sleeve and at least a portion of the bolt relative to the first end of the housing.

9 . The latch assembly of claim 8 , wherein rotation of the sleeve corresponds to rotation of at least a portion of the bolt around the longitudinal axis.

10 . The latch assembly of claim 8 , wherein the bolt includes an oblique surface, the oblique surface facing a first direction when the sleeve and the bolt are extended relative to the first end of the housing and facing an opposite second direction when the sleeve and the bolt are retracted relative to the first end of the housing.

11 . The latch assembly of claim 8 , wherein the bolt includes an outer housing and an inner body, the inner body coupled to the slide arm assembly and having a helical groove such that the outer housing is rotatable relative to the inner body.

12 . A latch assembly comprising:
a housing defining a longitudinal axis; a bolt slidably mounted at least partially within the housing and moveable between at least an extended position and a retracted position along the longitudinal axis; a cam rotatably mounted at least partially within the housing, the cam configured to couple to a torque blade rotatable around a rotation axis substantially orthogonal to the longitudinal axis; a slide arm assembly coupling the bolt with the cam such that rotation of the torque blade drives movement of the bolt; a sleeve rotatably mounted to the housing proximate the bolt, wherein a rotation position of the sleeve relative to the housing defines a backset position of the latch assembly; and a cam blocker selectively engageable with the cam and positionable between at least a knob configuration and a lever configuration, wherein when in the knob configuration, the cam is rotatable in both directions around the rotation axis to drive actuation of the slide arm assembly and movement of the bolt towards the retracted position, and wherein when in the lever configuration, the cam is rotatable in only a single direction around the rotation axis to drive actuation of the slide arm assembly and movement of the bolt towards the retracted position.

13 . The latch assembly of claim 12 , wherein the cam blocker includes a pin slidable on a C-shaped slot defined in the housing, the pin biased by a biasing block along the longitudinal axis, the lever configuration defined by the pin positioned at one of the ends of the C-shaped slot and the knob configuration defined by the pin centered within the C-shaped slot.

14 . The latch assembly of claim 13 , wherein the lever configuration includes a first lever configuration having the pin positioned at a first end of the C-shaped slot and preventing rotation of the cam in a first direction around the rotation axis and a second lever configuration having the pin positioned at a second end of the C-shaped slot and preventing rotation of the cam in an opposite second direction around the rotation axis.

15 . The latch assembly of claim 12 , wherein the bolt includes an outer housing and an inner body, the outer housing rotatable relative to the inner body, the inner body coupled to the slide arm assembly, and wherein rotation of the sleeve relative to the housing rotates the outer housing relative to the inner body.

16 . The latch assembly of claim 15 , wherein rotation of the outer housing relative to the inner body moves the outer housing relative to the inner body along the longitudinal axis.

17 . A method of installing a latch assembly on a door, the method comprising:
providing the latch assembly that includes a housing, a sleeve coupled to a face plate at a first end of the housing, a bolt extendable and retractable relative to the first end of the housing and having an oblique surface, a cam rotatably mounted to the housing and defining a rotation axis, a slide arm assembly coupling the cam to the bolt, and a cam blocker; configuring the latch assembly to a first backset position, wherein the first backset position is defined by rotating the sleeve relative to the first end of the housing; orienting the latch assembly relative to a swing orientation of the door; and setting the cam blocker to one of a knob configuration and a lever configuration, wherein when in the knob configuration, the cam is rotatable in both directions around the rotation axis to drive actuation of the slide arm assembly and retraction movement of the bolt, and wherein when in the lever configuration, the cam is rotatable in only a single direction around the rotation axis to drive actu
