Abstract:
A traction corner for releasably assembling a pair of hollow frame members having corresponding obliquely cut faces, said traction corner comprising:a right-angle body having a pair of arms, one of said arms being adapted to be inserted in one of said hollow frame members, the other of said arms being adapted to be inserted in the other of said hollow frame members; a connecting clip captively retained in said right-angle body, said connecting clip having a pair of wings, each of said wings having a hook portion at a free end thereof, said hook portions being adapted for captively engaging said wings in said hollow frame members, whereby said corresponding obliquely cut faces are face-to-face with a gap therebetween; an expansion mechanism connected to a corner of said right-angle body for exerting pressure against the junction of said pair of wings and against said right-angle body such that, with said wings being held captive in said hollow frame members, said free ends of said wings are displaced toward each other to pull said obliquely cut faces in tight co-planar engagement and under said exerted pressure of said expansion mechanism.
