Patent number: 10119325Abstract: A tilt latch system that comprises an actuator movable from a first position to a second position; a lock-out member movable from a retracted position to an extended position upon movement of the actuator from the first position to the second position; and an engagement member movable from an engaged position to a disengaged position upon movement of the actuator from the first position to the second position is provided. The actuator and the engagement member are maintained in the second and disengaged positions, respectively, when the lock-out member is in the extended position. The actuator and the engagement member are automatically biased to the first position and the engaged position, respectively, upon movement of the lock-out member from the extended to the retracted position. The tilt latch system may further comprise a lock-out device and/or be optionally utilized in a modular configuration.Type: GrantFiled: July 29, 2016Date of Patent: November 6, 2018Assignee: MILGARD MANUFACTURING INCORPORATEDInventors: Michael A.

Patent number: 8870250Abstract: The present invention relates to a sliding door latch having a locked and unlocked position for a sliding door having an open and closed position. The sliding door latch includes a handle assembly with a handle and a locking mechanism. The handle is a first position, wherein the locking mechanism is engaged and the sliding door latch is locked, to a second position, wherein the locking mechanism is disengaged and the sliding door latch is unlocked. The locking mechanism may prevent the handle from moving from the second position to the first position when the sliding door is open. The handle is pivotable between the first position and the second position only when the door is closed. Resistance forces may prevent the handle from moving from the second position to the first position when the sliding door is closed without an application of force by a user.Type: GrantFiled: June 25, 2013Date of Patent: October 28, 2014Assignee: Milgard Manufacturing IncorporatedInventors: Gordon H.
