Patent number: 7503597Abstract: An exit device for a door having a first stile, a second stile, and a midrail coupled to the first and second stiles and defining a cutout. The exit device comprises a latching mechanism positioned in the cutout. A pushbar positioned in the cutout encloses the latching mechanism and has a front surface. The front surface is positionable in an extended position and a depressed position. The front surface defines a plurality of apertures which communicate with the latching mechanism. A lid slideably engages the front surface and has a closed position and an open position. The lid covers the plurality of apertures in the closed position.Type: GrantFiled: June 18, 2004Date of Patent: March 17, 2009Assignee: Dor-O-Matic, Inc.Inventors: Richard Bettin Cohrs, Jr., Eric K.

Patent number: 7249477Abstract: A control assembly configured for a narrow stile door and for interaction with an exit device. The control assembly provides a means to translate user input, such as rotating a lever to operate a centercase. The control includes a slider for sliding movement within a housing between a first position extending a latchbolt of the exit device and a second position withdrawing the latchbolt. The control assembly configuration incorporates a swivel locking latch rotatable into the path of the slider to prevent the slider from moving out of the first position.Type: GrantFiled: July 15, 2005Date of Patent: July 31, 2007Assignee: Von Duprin, Inc.Inventors: David V. Toloday, Marlin Austin, Loren D. Mueller, Paul D. Bilyeu

Patent number: 7118141Abstract: A securing mechanism for coupling an exit device to a door. The securing mechanism comprises a bracket coupled to the exit device and a shaft having a first end and a second end and defining a longitudinal axis. The bracket defines a first aperture and a second aperture. The first end of the shaft extends through the first aperture and the second end of the shaft extends through the second aperture. The securing mechanism also comprises a first anchor slideably coupled to the shaft and moveable along the longitudinal axis between a first locked position and a first unlocked position and a second anchor slideably coupled to the shaft and moveable along the longitudinal axis between a second locked position and a second unlocked position. The first anchor frictionally engages the door in the first locked position and the second anchor frictionally engages the door in the second locked position.Type: GrantFiled: August 30, 2002Date of Patent: October 10, 2006Assignee: Dor-O-Matic, Inc.Inventors: Richard Bettin Cohrs, Jr., Eric K.
