20080229680 | WALL ANGLE WITH PRE-PUNCHED LOCATING TABS - A wall angle for a suspended ceiling, which may either be a drywall suspended ceiling or a lay-in tile suspended ceiling, has a cross-section forming a substantially right angle of the vertical leg and a horizontal leg. The horizontal leg is adapted to support an inverted tee-runner that has a vertical web and opposed flanges, the opposed flanges being adapted to rest on the horizontal leg of the wall angle. The horizontal leg is formed with a plurality of pairs of locating tabs, at least one tab in each pair being upwardly extending and vertically-oriented. The tabs in each pair are spaced apart a distance sufficient to accommodate the width of the opposed flanges of the tee-runner. At least one of the tabs in each pair has a downwardly extending detent adapted to permit installation of a tee-runner, but to inhibit removal of the tee-runner. The pairs of tabs are spaced, on center, a pre-determined distance that depends upon the intended application of the wall angle. | 09-25-2008 |
20080236068 | DRYWALL CHANNEL WITH PRE-PUNCHED LOCATING TABS - A wall channel for a drywall ceiling has a generally U-shaped cross-section with a vertical leg interconnecting two generally-horizontal legs. The lower horizontal leg is adapted to support an inverted tee-runner that has a vertical web and opposed flanges, the opposed flanges being adapted to rest on the horizontal leg of the wall angle. The lower horizontal leg is formed with a plurality of pairs of locating tabs that are spaced apart a distance sufficient to accommodate the width of the opposed flanges of the tee-runner. The upper horizontal leg is formed with a plurality of pairs of locating tabs that are spaced apart a distance sufficient to accommodate the width of the reinforcing bulb of the tee-runner. | 10-02-2008 |
20100077687 | ROTARY STITCH FOR JOINING SHEET METAL STOCK - A method for securing two pieces of sheet material is provided using a stitch preferably made by sequentially passing the grid member through two die sets. The first die set lances a strap out of the two sheets of metal such that, at the approximate center or midsection of the strap, the first layer of material is displaced completely out of the plane defined by the web, while the second layer is only partially displaced out of the plane of the web so that a portion of the second layer remains in the space vacated by the first layer of the strap. The lanced strap is then passed through a second die set, in which the first and second layers of the strap are deformed or “swaged” such that the first layer is flattened and expanded in width beyond the edges of the hole in the web created when the strap was lanced. This provides interference such that the first layer of the strap cannot pass back through the hole. Additionally, the strap in the second web is deformed and displaced into the first web to bond the two together. | 04-01-2010 |
20100242396 | Suspended Ceiling System - A grid system is provided that is particularly suited for the suspended ceiling system that varies in the vertical plane. An elongated carrier tube is provided the spans substantially the width of the grid system that has a slot therein adapted to receive the strengthening bulb of a main runner. A clip is provided that seats on the carrier tube that has opposed faces for capturing the bulb of the runner, so as to secure the runner to the tube carrier. | 09-30-2010 |
20110067337 | Concealed Ceiling Panel System - A flexible ceiling panel is preferably formed from sheet metal, such as aluminum sheet. Each ceiling panel has a generally rectangular shape (corresponding in width to the spacing between the main runners) and is formed with a hem on all four edges. A series of bendable tabs are formed integrally with the hem of the panel. To secure the panel to the associated grid system, the tabs are folded upwardly and outwardly from the panel along two axes to secure the panel to the grid system. Alternatively, a plurality of separate spring clips is used to secure the panel to the grid system. Each clip includes a first leg adapted to have at least a portion thereof received in the hem of the ceiling panel. A second leg extends generally perpendicularly from the first leg and includes a detent extending toward the first leg, the detent being adapted to secure the clip to the flange of the runner. | 03-24-2011 |
20110078968 | Single Strip - Double Web Ceiling Grid Member - A runner for a suspended ceiling grid is roll-formed from a single strip of sheet metal so as to have a generally symmetrical appearance about a vertical center line, with a double vertical web and a double-thickness flange for supporting ceiling tiles. The bottom surface of the flange is continuous across its exposed surface, so that there is no visible juncture of the opposed flanges with the double web when viewed from below, thus providing an aesthetically more-pleasing appearance. | 04-07-2011 |
20110314761 | Accessible Concealed Suspended Ceiling System - A suspended ceiling system is provided comprising at least first and second parallel inverted tee-runners. Each tee-runner comprises a horizontal flange and a vertical web, with the vertical web having at least two spaced openings therein. At least one ceiling panel is associated with the parallel tee-runners. The ceiling panel has opposed side walls and opposed end walls, with a pair of first tabs formed at one end of the ceiling panel and a pair of second tabs formed at the opposite end of the panel. The first tabs are relatively longer than the second tabs and have a length sufficient so that each first tab extends through one of the spaced openings in the web of the first inverted tee-runner and rests on the flange of the first tee-runner, with the second tabs being supported by the flange of the second tee-runner. | 12-29-2011 |
20130031863 | Accessible Concealed Suspended Ceiling System - A suspended ceiling system is provided comprising at least first and second parallel inverted tee-runners. Each tee-runner comprises a horizontal flange and a vertical web, with the vertical web having at least two spaced openings therein. At least one ceiling panel is associated with the parallel tee-runners. The ceiling panel has opposed side walls and opposed end walls, with a pair of first tabs formed at one end of the ceiling panel and a pair of second tabs formed at the opposite end of the panel. At least one of the first tabs is relatively longer than at least one of the second tabs, and has a length sufficient so that it extends through one of the spaced openings in the web of the first inverted tee-runner and rests on the flange of the first tee-runner, with the second tabs being supported by the flange of the second tee-runner. | 02-07-2013 |
