Clip for joining and maintaining alignment of acoustical tile in a starting row thereof

A metal clip for joining acoustical tiles and contacting a support structure therefor to hold the tiles in the starting row of a suspended acoustical ceiling structure in edge-aligned relationship with each other, said clip comprising:

• a. a body member having planar, longitudinally-extending side portions which lie in a single plane, said body member including an intermediate portion which joins the side portions of the body and has a central portion which is elevated above the plane thereof, said intermediate portion including side portions which extend downwardly from the central portion thereof in planes which are at an angle to each other and to the plane of the sides, said body member being adapted to overlie the back surface portions of adjacent tiles adjacent their opposing edges and extend lengthwise therealong into abutting relationship with a support member for said tiles;
• and
• b. prong means on each side portion of said body adjacent one end only thereof, the opposite end being devoid of prongs, said prong means comprising substantially triangularly-shaped portions of the longitudinally-extending side portions of said body which have been struck downwardly therefrom and have flat surfaces which lie in a plurality of planes parallel to each other and substantially perpendicular to the plane of the sides, the prongs on each side being in longitudinal alignment with each other and substantially equally spaced apart, said prong means being adapted to penetrate the back surface portions of adjacent tiles adjacent their opposing edges at a point remote from a tile support member when the end of said body which is devoid of prongs is in abutting relationship with said tile support member, thereby securing the tiles against movement relative to each other and to the support member.
