Bar joist supported suspension clips

In combination with a bar joist of the type including a pair of closely laterally spaced horizontally elongated upright flanges including exposed upper marginal edge portions, a resilient clip including a pair of upstanding arm portions having upper and lower ends, at least the upper ends of said arm portions being spaced apart in the static condition of said clip, means joining said lower ends and including suspension structure adapted to suspend a selected article therefrom, said upper ends of said arm portions including integral downwardly and oppositely outwardly inclined catch flanges supported therefrom with each arm portion upper end and the associated catch flange defining a downwardly opening channel on the outer side of the corresponding arm portion remote from the other arm portion upper end, said catch flanges being relatively downwardly divergent and including remote upwardly convergent outer side wedge surfaces for camming the upper ends of said arm portions toward each other as said clip is upwardly displaced between said flanges from therebelow to a level with the lower ends of said catch flanges disposed above said upper marginal edge portions, said clip being sufficiently resilient, after the upper ends of said arm portions have been cammed together for passage between said flanges, to reassume said static positions thereof, whereby said channels will be aligned with said upper marginal edge portions and seatingly receive the latter therein when said clip is subsequently slightly lowered relative to said flanges and said clip will be anchored to said flanges against further downward displacement relative thereto, the spacing between the remote sides of the lower ends of said catch flanges, when the upper ends of the opposing sides of said arm portions are abutted against each other, being at least slightly greater than the spacing between the adjacent sides of said upright flanges, whereby upward insertion of the upper ends of said arm portions between the adjacent sides of said upright flanges necessitates not only flexure of said arm portions to positions with the adjacent sides of the upper end portions thereof abutted together but also inward flexure of the lower ends of said catch flanges toward the opposing outer sides of said arm portions.
