Patent number: 9021745Abstract: An exit device includes a rail having opposite first and second ends and a rear portion with a first opening adjacent the first rail end for attachment to the door surface, the first rail end further having a front portion that inhibits access to the first rail opening in a direction normal to the rail rear portion. The method for installing it includes securing a mount having a cantilevered portion extending therefrom to the door at the surface first end such that the mount cantilevered portion provides a space between the cantilevered portion and the door and placing the rail against the door surface such that the mount extends through the first rail opening, sliding the rail to engage the rail rear portion adjacent the first rail opening between the mount cantilevered portion and the door and securing the second rail end to the door surface.Type: GrantFiled: January 21, 2013Date of Patent: May 5, 2015Assignee: Assa Abloy Inc.Inventors: Thomas Harris, David Eveland, John F.

Patent number: 8991881Abstract: An anti-ligative ergonomic type door-knob primarily of the institutional type, essentially serving to defeat the effort of a temporarily mentally-depressed room occupant from succeeding in committing self-hanging via contrived ensnaring by which to secure a cord like hanging-noose. Generic-variant embodiments of my anti-ligative doorknob are set forth, including both a circular and semi-circular escutcheon-plate for I-shaped V-shaped Y-shaped X-shaped fin-levers, and also a non-finned hemispherical iteration. The novel critical minimum approximate 40-degree anti-ligative principle of my LIFESTARâ„¢ doorknobs reliably prevents a person ensnaring any heretofore problematically hazardous to portion of the door-knob assembly, while my optionally cooperating door latchbolt is formed to a matching critical minimum approximate 40-degree anti-ligative tri-beveled latchbolt as well.Type: GrantFiled: May 5, 2014Date of Patent: March 31, 2015Assignee: Assa Abloy, Inc.Inventor: Steven J.

Patent number: 8517747Abstract: A data transfer hinge is disclosed. Embodiments of the present invention provide a door hinge that facilitates transmission of data from LAN wiring in a building through a door frame to a door mounted device. Power and ground connections can also pass through the hinge. Channels (207, 211, 607, 611) run in each leaf from an edge coincident with the knuckles of the leaf to a passageway (110, 112) in the face of the leaf. Twisted pairs of data wires (106, 108) having a specified number of twists per unit length run through the passageway and the channels in the leaves. Each wire of a twisted pair is of a gauge and has insulation of a specified thickness and permittivity so as to cooperate with the channel to maintain an even distribution of capacitance and appropriate impedance for connection within a local area network.Type: GrantFiled: March 26, 2010Date of Patent: August 27, 2013Assignee: Assa Abloy, Inc.Inventors: Mark Daniel Bryla, Eriks A. Zusmanis, Paul Marquis

Patent number: 7856856Abstract: An independently interactive interconnected lock includes an interconnecting mechanism that retracts a latchbolt and a deadbolt when an inner handle is moved between an up position, an intermediate position and a down position. The deadbolt is retracted by a deadbolt lock mechanism as the inner handle moves from the up position to the intermediate position. The latchbolt is retracted by a latchbolt lock mechanism as the inner handle continues to move from the intermediate position to the down position. When the inner handle is moved to the up position, both the latchbolt and deadbolt are extended and the deadbolt lock mechanism is disconnected from the latchbolt lock mechanism such that manipulation of the latchbolt lock mechanism to retract the latchbolt does not retract the deadbolt. The inner handle operates with low handle torque because the deadbolt and the latchbolt are not retracted simultaneously.Type: GrantFiled: February 20, 2008Date of Patent: December 28, 2010Assignee: Assa Abloy, Inc.Inventor: Vladimir Shvartz
