Publication number: 20240076907Abstract: A center slide assembly for a multi-point exit device. Upper and lower spool assemblies may be displaced from first positions to second positions along an inner region of a center slide. The displacement of the spool assemblies may displace upper and lower pull cables so as to retract latch mechanisms from extended positions to retracted positions. A first latching pin may be displaced, along with the displacement of the upper spool assembly, along an abutment surface of a tilting link so as to pivotally displace the tilting link from an unlocked position to a locked position. Displacement of the lower spool assembly may displace a second latching pin to a position wherein the second latching pin may be received and retained within a jog of the tilting link when the tilting link is in the locked position, which may thereby retain the associated latch mechanism in the retracted position.Type: ApplicationFiled: March 7, 2023Publication date: March 7, 2024Inventors: Sushanth Anand Rao Kondi, Mohammed Maksood Ali, Kemparaju Putaswamy, Michael D. Coleman, Matthew S. Graham

Patent number: 11359422Abstract: Latch mechanisms adapted to prevent unauthorized displacement of a latch bolt from an extended, locked position to a retracted, unlocked position. The latch mechanisms prevent the failure of a latch bolt of one latch mechanism to return to an extended lock position from interfering with the ability of a latch bolt of an inter-related latch mechanism from being able to return to an extended, locked position. Further embodiments provide a mounting bracket mounted to a door to allow the associated latch mechanism to be indirectly secured to the door. Additionally, the mounting bracket may have a plurality of mounting orifices that allow the mounting bracket to be used with a wide range of latch mechanisms, as well as provide adjustable attachment of the latch mechanism to the mounting bracket.Type: GrantFiled: October 8, 2019Date of Patent: June 14, 2022Assignee: Schlage Lock Company LLCInventors: Paul R. Arlinghaus, Mohammed Maksood Ali, Jonah M. Pattar, Kemparaju Putaswamy, Sushanth Anand Rao Kondi, Matthew S. Graham, Subashchandra Rai, Keshav Tantri

Publication number: 20180340353Abstract: In one form, a multipoint locking assembly included a first latch device, a second latch device, and a mortise assembly coupled to the first and second latch devices. The mortise assembly may comprise a first transmission coupled to the first latch device via a first flexible member, a second transmission coupled to the second latch device via a second flexible member, and an actuation assembly operable to actuate the first and second transmissions. At least one of the transmissions comprises a slack removal device operable to remove slack in the flexible member to which it is coupled, thereby ensuring proper transmission of pulling forces between the transmission and the latch device.Type: ApplicationFiled: May 1, 2018Publication date: November 29, 2018Inventors: Mohammed Maksood Ali, Sushanth A Kondi, Kemparaju Putaswamy, Matthew S.
