ABSTRACT:
An improved channel beam clamp and locking skirt assembly for a suspended ceiling grid system. The channel beam clamp has a recess for receiving a channel of the ceiling grid system. The channel beam clamp is suspended from the channel in an essentially vertical plane. The channel beam clamp has a plurality of prongs extending from the lower end thereof. Each of these groups has an inwardly curved portion at its lower end which bulge outwardly from the vertical plane so that a pair of opposite prongs of the plurality of prongs define a receiving space therebetween for receiving a bulb of a ceiling grid member of the ceiling grid system. The assembly includes an inverted essentially U-shaped locking skirt which has a pair of legs depending from a slotted horizontal base. The lower end of the channel beam clamp with its plurality of prongs is slid through the slot and the channel beam clamp is slid upwardly. The plurality of prongs can again spread apart after they have passed through the slot. The bulb of the ceiling grid system is then introduced into the receiving space between the plurality of prongs so as to press them toward each other and to clamp the bulb therebetween. A first leg of the pair of legs of the locking skirt has an inwardly bent portion which extends underneath and lower edge of at least one of the prongs and thereby inhibits an upward sliding movement of the locking skirt along the channel-beam clamp after assembly.
