A clip is provided for securing a cross tee to a main runner in a suspended ceiling grid system. The clip comprises a first leg configured to extend through the slot in the web of the main runner so as to lie alongside the web of a cross tee whose connector extends through the slot in a direction opposite to that of the first leg; a second leg extending generally perpendicularly to the first leg so as to lie alongside the web of the main runner; and a third leg extending generally perpendicularly to the second leg and generally parallel to the first leg. The third leg is sized to extend through an aperture in the web of the main runner and then be bent to lie alongside the web of the main runner on a side opposite to that of the second leg.

A cross member for a narrow channel in a suspended ceiling grid comprising a carrier and a cover, the carrier having a web and a planar flange on a lower edge of the web, end connectors at opposite ends of the carrier web, the cover having a three-dimensional cross-section with an overall width generally equal to the width of the carrier flange and integral bendable tabs, the tabs being adjacent the ends of the cover and short in comparison to a length of the cover, the tabs being constructed to be manually folded over the flange of the carrier to lock the cover to the carrier.
摘要:
A short cross member for a narrow utility channel formed of malleable sheet metal and having a vertical double ply web and a horizontal flange symmetrically disposed on both sides of a lower edge of the web, integral end connectors formed on each end of the cross member from sheet material contiguous with the web, the integral end connectors being arranged to support the flange in coplanar relation with flanges of the channel, the end connectors and the web being weakened at a predetermined vertical line whereby the cross member can be assembled in a narrow channel by bending at the associated line of weakness to shorten the effective overall length of the cross member.

A lighting fixture for installation in a ceiling grid includes a lighting assembly and at least one pivotable rail assembly attached to the lighting assembly. The rail assembly includes at least one mounting bracket, a rail and a spring. The rail is pivotable relative to the at least one mounting bracket. To insert the lighting fixture into the ceiling grid, the rail is rotated relative to the mounting bracket such that the rail will clear the ceiling grid, thereby compressing the spring. The lighting fixture is inserted into the ceiling grid and the rail is released. The compression of the spring is relaxed, and the rail rotates back into its original position. The rail, now extending beyond the boundary of the ceiling grid, rests on the ceiling grid is thereby secured within the ceiling grid.
摘要:
An electrically powerable grid element having first and second conductive members of opposing polarity. The grid element includes first and second electrical access slots which expose the conductive members. The grid element includes a tap which has a conductor engaging means which forms an electrical connection with the first and second conductors via the first and second electrical access slots.

A roll formed sheet metal grid runner, and method of its manufacture, for a suspended ceiling grid having indexing tabs stamped from a central web of the runner profile, the tabs being effective to reliably locate ceiling panels and, when the grid runner is nested with other identical runners in a package, avoid marring of visible surfaces.

An assembly for connecting a sprinkler to a branch line of a fire suppression system includes a flexible conduit having one end attached to the branch line. The opposite end is attached to the sprinkler. An adapter may be positioned between the conduit and the sprinkler, between the conduit and the branch line, or between the conduit and both the branch line and the sprinkler. The adapter contains a rotating joint which prevents torque from being applied to the conduit. The joint may be a coaxial joint.

In a panel suspended ceiling for seismic prone areas, a superstructure extends from and above the ceiling grid. The superstructure is engaged within a lateral support bar that slidably supports the superstructure, and ceiling, during a seismic event.
