Perimeter clip

DETAILED DESCRIPTION OF THE INVENTION As seen in FIG.
7, a vertical dry or plastered wall 20 is supported from structure 21.
The wall 20 forms one side of a room within a building and extends from the floor to a structural ceiling.
A dropped ceiling of the grid type has a runner or beam 22 in the form of an inverted T.
Beam 22 has a flange portion 23, a web portion 25, and a bulb portion 26.
Beam 22 is suitably formed from a longitudinally extending flat strip bent to form the beam portions.
A cover piece 27 is wrapped around the flange portion 23 of the beam and is painted in a desired color.
Such beams are well known in the art and extend in grid fashion throughout the ceiling to form the grid structure for the acoustical tiles that are laid in the grids.
A wall molding 30 is secured to wall 20 by screws or fasteners 31.
The wall molding 30 extends horizontally along the wall at the desired drop ceiling height.
Molding 30 forms an angle in cross section having a vertical face 32 and a horizontal ledge 33.
The molding 30 is formed of a continuously extending strip bent into folds 35 to form smooth edges, and bent at a right angle along the longitudinal center line to form face 32 and ledge 33.
The face 32 and ledge 33 each are of a width equal to the width of the flange portion 23 of beam 22, so when the ceiling is in place, the wall molding ledge 22 and flange portion 23 appear identical.
Beam 33 has an offset portion 37, so that when beam 22 at its end is rested on shelf 33 as seen in phantom at 38 in FIG.
7, the lower surface of shelf 33 and flange portion 23 extends in the same plane to present a uniform appearance.
The perimeter clip 40 of the invention is used to secure the end of beam 22 to wall molding 30.
Clip 40, as seen particularly in FIGS.
1, 3 and 7, is in the form of a right angle having legs 41 and 42.
Leg 41 is of a single thickness of sheet metal and has a tab or ear 43 lanced out in a U-shape with the top of the U at 45 remaining integral with leg 41.
A space 46 as seen particularly in FIGS
