Patent number: 8635022Abstract: A locking mechanism is provided for a lock body and a rotatable key plug. The locking mechanism comprises pins having recesses, each of the pins adapted to be disposed in pin bores in the key plug for reciprocal and rotational movement. An elongated spring member simultaneously engages and biases the pins toward a keyway in the key plug. A locking bar moves between a first position and a second position where at least a portion of the locking bar is received in the recesses in the pins. The locking bar is prevented from moving to the second position unless the pins are in a position where the recesses are aligned with the locking bar. Upon insertion of a key in the keyway the pins are moved axially or rotated for aligning the recesses in the pins with the locking bar so the key can rotate the key plug.Type: GrantFiled: April 20, 2012Date of Patent: January 21, 2014Assignee: Corbin Russwin, Inc.Inventors: David T. Nguyen, Damon J. Lenk

Patent number: 6616203Abstract: A door latch operator mount comprises a coupling member and a bearing member. The coupling member includes a plurality radial flanges and an integral resilient arcuate tab member projecting angularly outwardly of the outer surface of the coupling member. The coupling member is mounted to a door for receiving the bearing member. The bearing member has an opening for rotatably receiving a shaft of the latch operator. The bearing member also includes a plurality of flanges and an arcuate channel which tapers in depth. When the bearing member is positioned against the coupling member, the distance of the bearing member flanges from the surface of the coupling member is less than the distance of the coupling member flanges form the surface. The tab member is received in the deeper portion of the arcuate channel.Type: GrantFiled: August 26, 2002Date of Patent: September 9, 2003Assignee: Corbin Russwin, Inc.Inventors: Damon J. Lenk, Zakhary Fayngersh

Patent number: 6393878Abstract: A mortise lock is provided including a housing for a latch bolt and a deadbolt which are mounted in the housing for movement between a retracted position where the latch bolt and deadbolt are inside the housing and an extended position where a portion of the latch bolt and deadbolt extend from the housing. A key-operated cylinder in the housing operates to move the deadbolt between the retracted and extended positions. A latch operator is also provided for retracting both the latch bolt and the deadbolt. A moveable blocking element in the housing prevents movement of the latch operator in one position of the blocking element. A locking lever operatively connects the deadbolt and the blocking element so that when the deadbolt is extended the blocking element is automatically moved to the position blocking the latch operator. The locking lever comprises an arm member integral with the locking lever.Type: GrantFiled: May 22, 2000Date of Patent: May 28, 2002Assignee: Corbin Russwin, Inc.Inventors: Zakhary Fayngersh, Damon J.

Patent number: 6349982Abstract: A reversible mortise lock comprises a latch bolt which is removable from the housing for ease of reversal. A securing member is disposed inside the lock housing for releasbly holding the latch bolt in the housing. The securing member includes a securing element having a blocking surface biased into engagement with the latch bolt for securing the latch bolt to the securing member. The securing element has a surface accessible from outside the lock housing which when pressed releases the latch bolt from the securing member. Once the latch bolt is freed, the latch bolt can be completely removed from the lock housing, reversed and reinstalled. This releasing surface is only accessible through the side walls of the lock housing. Therefore, latch bolt reversal must be performed before the lock is installed in a door. Once the lock is installed, the latch bolt cannot be reversed because the latch bolt cannot be removed from the lock.Type: GrantFiled: July 2, 1999Date of Patent: February 26, 2002Assignee: Corbin Russwin, Inc.Inventors: Zakhary Fayngersh, Damon J.

Patent number: 5414894Abstract: A door closer (20) is attachable to a door (24) and is formed with a chamber (44) in which a piston element (50) is movable to move fluid from the chamber to a reservoir (82) upon opening of the door. After the door (24) has been opened to a position, for example, of sixty to seventy-five degrees, continued opening of the door causes the fluid to be compressed within the chamber (44) and to be directed only through a back check valve (95) to the reservoir (82). This results in the development of an adjustable "back check" condition to provide a counterforce to the continued opening of the door. The adjustable valve (95) includes a spring biased ball (144), the biasing of which must be overcome by the force of the fluid being compressed in the chamber (44) to allow for fluid to pass through the valve to the reservoir (82).Type: GrantFiled: October 1, 1993Date of Patent: May 16, 1995Assignee: Corbin Russwin, Inc.Inventor: Zakhary Fayngersh

Patent number: 5386614Abstract: A door closer (20) is attachable to a door (24) and includes a cylinder (36) which forms a chamber (44) in which a piston element (50) is movable to move fluid from the chamber to a reservoir (82) upon opening of the door. After the door (24) has been opened to a position, for example, of ninety-five to one hundred degrees, continued opening of the door causes the fluid to be compressed within the chamber (44) and to be directed only through a back check valve (95) to the reservoir (82). This results in the development of an adjustable "back check" condition to provide a counterforce to the continued opening of the door. A passageway (150) is formed in cylinder (36) to allow fluid to flow relatively freely from chamber (44) to reservoir (82) until an inward end (56) of piston element (50) has travelled a prescribed distance "x." This prescribed distance of travel represents the opening of door (24) to ninety-five to one hundred degrees from the door's normally closed position.Type: GrantFiled: January 8, 1993Date of Patent: February 7, 1995Assignee: Corbin Russwin, Inc.Inventor: Zakhary Fayngersh
