Patent application number | Description | Published |
20120023854 | GRID RUNNER - A roll-formed grid runner comprising a sheet metal strip folded into an upper hollow single wall reinforcing bulb, a double wall web below the bulb, a channel extending laterally from both sides of a lower end of the web to a bend and upwardly from the bend to a panel supporting elevation, the bend on each side of the web existing at a longitudinally extending score line where a thickness of the strip is locally reduced. | 02-02-2012 |
20120180420 | WALL BRACE SUPPORT FOR ACOUSTICAL CEILING TEE - A wall brace support for an acoustical ceiling tee having a bulb includes an elongated main portion having two ends; a wall attachment tab at one of the ends, the tab being operable to abut the wall and receive at least one fastener therethrough to fasten the tab to the wall; and an acoustical ceiling tee attachment structure at the other end, the structure being operable to receive at least one fastener therethrough to fasten the structure to the bulb at a location spaced away from the wall. | 07-19-2012 |
20130111963 | GRID RUNNER - A roll-formed grid runner comprising a sheet metal strip folded into an upper hollow single wall reinforcing bulb, a double wall web below the bulb, a channel extending laterally from both sides of a lower end of the web to a bend and upwardly from the bend to a panel supporting elevation, the bend on each side of the web existing at a longitudinally extending score line where a thickness of the strip is locally reduced. | 05-09-2013 |
20140000205 | GRID RUNNER TO PERIMETER TRIM CLIP | 01-02-2014 |
20140037366 | GRID RUNNER INTERSECTION CLIP - A sheet metal clip for connecting the ends of three or four grid runners with their longitudinal axii intersecting at a common center and at obtuse or acute angles relative to each other, the clip having a leg for each one of the grid runners, each leg, in use, extending in a vertical plane from the center and being permanently bendable at the center to allow the leg to be adjusted to a desired angle of a respective grid runner. | 02-06-2014 |
20140215957 | CLIP FOR PERIMETER TRIM - A single piece sheet metal clip including a trim engaging part and a mounting part extending or extendable from the trim engaging part at a right angle, the trim engaging part having a limited height when the clip is tilted from a vertical portion and a height greater than the limited height when upright whereby the trim engaging part may be inserted between opposed channels on a rear side of a trim strip and upper and lower edges are trapped in a respective channel when rotated from the tilted position to an upright position, the trim engaging part having an integral element resiliently deflected in a channel when the clip is turned upright, said resilient element releasably locking the clip against a reversal of said movement and thereby maintaining the trim engaging part trapped in said channels. | 08-07-2014 |
20140311078 | CEILING PANEL WIRE ANCHOR - A sheet metal fastener and method of use with a low density porous ceiling panel, the fastener comprising a plurality of blades adapted to be manually driven into a backside of a low density fibrous ceiling panel core, each blade being arranged to be pivoted about a horizontal axis in a direction opposite another one of the blades while embedded in the core to fix the fastener to the panel and an upstanding structure attached to said blades adapted to project upwardly from a rear side of the panel and having an aperture for receiving a suspension wire. | 10-23-2014 |
20150033657 | ACCESSIBLE STABILIZER BAR - An elongated stabilizer bar for maintaining a pair of grid runners in parallel upright positions to support a panel on respective grid runner support surfaces, the stabilizer bar having a horizontal leg and a vertical leg, the horizontal leg having self-penetrating tabs arranged to pierce and thereby grip a core of the panel to fix the stabilizer bar to the panel, a vertical leg having a vertical slot at each end, the slot having an open bottom, the slot having a horizontal width adapted to receive and confine an upper reinforcing bulb of a respective one of the pair of grid runners to thereby restrain the respective grid runner against excessive bowing and twisting deflection. | 02-05-2015 |
