Patent number: 7926238Abstract: A stab-in connector that locks with an opposing identical connector, through a slot in the main beam of a suspended ceiling grid. The connector has a straight locking latch that is cantilevered from a bend at a base of the connector. The bend is in the form of an arc. The bend forms a pivot for the latch. Contact between the cantilevered straight locking latch and the side of the slot is delayed as the connector is being stabbed into the slot. During the delay, the connectors are positioned within the slot, and relative to each other, so that substantially less force is needed than the force that was necessary to engage prior art stab-in connectors into locking position.Type: GrantFiled: January 9, 2004Date of Patent: April 19, 2011Assignee: Worthington Armstrong VentureInventors: Brett W. Sareyka, Yu Lin, William J. Platt

Patent number: 7614195Abstract: Joint clips of the invention are used in grids for suspended ceilings, at selected intersections, to create separate areas of ceiling that move independently of one another during an earthquake, to prevent a buildup of momentum in the entire ceiling. In one embodiment disclosed herein, the clips extend laterally of a selected main beam, and are formed of a pair of loosely connected identical segments that are slidably secured to a selected main beam by a cut-out in the segments. The clip extends laterally across a selected main beam and slidably receives the end of a cross beam in a pocket of the clip that extends laterally on each side of the selected main beam.Type: GrantFiled: August 27, 2007Date of Patent: November 10, 2009Assignee: Worthington Armstrong VentureInventors: William J.

Patent number: 7520095Abstract: The invention relates to a right-angle connection in the grid of a suspended ceiling, between inverted T-beams having a vertical web extending between a bulb at the top and flanges at the bottom. A connector on the end of a cross beam hooks into a slot in the web of a main beam. The connector has a plastic encasement that forms abutments about a metallic core. The abutments position the connector within the slot in the web, and prevent further entry of the connector into the slot, under normal conditions. The plastic abutments melt away during a fire, so that the beam can expand longitudinally into the slot to relieve stresses in the beam, without the beam buckling. Ridges on the bottom of the metallic core that engage the web at the bottom of the slot, prevent pullback of the connector from the slot, during a fire, to prevent the ceiling from sagging or drooping.Type: GrantFiled: May 17, 2005Date of Patent: April 21, 2009Assignee: Worthington Armstrong VentureInventors: William J. Platt, Yu Lin
