Abstract
A latch assembly is provided where a latch bolt is moveable to open and close a door by unblocking pivotal movement of the latch bolt. Turning a door knob or door handle does not directly result in a corresponding retraction of the latch within a sleeve, but rather unblocks the bolt to freely pivot away from a latched position. In some embodiments, the latch assembly may include a sleeve that allows for a backset to be infinitely adjusted relative to an aperture of the sleeve. In some embodiments, the latch assembly may further include a dead latch to provide additional security against forced entry.
Claims19
A latch assembly comprising:
- a housing having a first end and an opposite second end defining a longitudinal axis, wherein at least one opening is defined within the housing proximate the second end;
- a bolt disposed at the first end of the housing, the bolt selectively movable between at least an extended position and a retracted position, wherein in the extended position, the bolt extends at least partially out of the first end of the housing, and in the retracted position, the bolt substantially retracts into the first end of the housing;
- a latch arm having a first end and an opposite second end extending along the longitudinal axis and disposed within the housing;
- and
- a latch actuator disposed proximate the second end of the housing, the latch actuator including a receiver rotatable around a transverse axis orthogonal to the longitudinal axis and configured to receive a torque blade of a door handle and receive the second end of the latch arm, the receiver being in open communication with the at least one opening of the housing, wherein upon rotation of the receiver, the latch actuator moves the latch arm such that the first end of the latch arm is selectively engageable with the bolt, and wherein the receiver is slidingly coupled to the second end of the latch arm and the latch actuator is movable along the longitudinal axis relative to the first end of the housing such that a backset position of the receiver is adjustable along a length of the latch arm.

A latch assembly comprising:
- a housing having a first end and an opposite second end defining a longitudinal axis, wherein at least one opening is defined within the housing proximate the second end;
- an inner sleeve disposed within the housing proximate the first end and slidable along the longitudinal axis;
- a bolt pivotably coupled to the inner sleeve, the bolt selectively movable between at least an extended position and a retracted position, wherein in the extended position, the bolt extends at least partially out of the first end of the housing, and in the retracted position, the bolt substantially retracts into the first end of the housing;
- a latch arm having a first end and an opposite second end extending along the longitudinal axis and disposed within the housing;
- and
- a latch actuator disposed proximate the second end of the housing and aligned with the at least one opening, wherein the latch actuator is movable along the longitudinal axis relative to the first end of the housing such that a backset position of the latch assembly is adjustable, the latch actuator including a receiver rotatable around a transverse axis orthogonal to the longitudinal axis and configured to receive a torque blade of a door handle and receive the second end of the latch arm, wherein based on a rotational position of the receiver, the first end of the latch arm is selectively engageable with the bolt to prevent the bolt from pivoting.

A handle assembly comprising:
- at least one handle;
- a torque blade coupled to the at least one handle and rotatable around a first axis via the at least one handle;
- and
- a latch assembly comprising:
- a housing having a first end and an opposite second end defining a second axis orthogonal to the first axis, wherein at least one opening is defined within the housing proximate the second end;
- a bolt disposed at the first end of the housing, the bolt selectively movable between an extended position and a retracted position, wherein in the extended position, the bolt extends at least partially out of the first end of the housing, and in the retracted position, the bolt substantially retracts into the first end of the housing;
- a latch arm having a first end and an opposite second end extending along the second axis and disposed within the housing;
- and
- a latch actuator having a receiver aligned with the at least one opening of the housing, the receiver coupled to the torque blade and rotatable around the first axis, the receiver also coupled to the second end of the latch arm, wherein upon rotation of the at least one handle, the latch actuator moves the latch arm such that the first end of the latch arm is selectively engageable with the bolt, and wherein the receiver is slidingly coupled to the second end of the latch arm and the latch actuator is movable along the second axis relative to the first end of the housing such that a backset position of the receiver is adjustable along a length of the latch arm.
