Adjustable joint between panel frames
Abstract
Abstract EACH OF A PAIR OF FRAMES HAS A SIDE MEMBER WITH AN OUTWARDLY OPENING CHANNEL PROVIDED WITH PARALLEL SIDE FLANGES HAVING TRANSVERSELY ARCUATE INNER SURFACE EXTENDING LENGTH-WISE THEREOF. THESE SIDE MEMBERS ARE DISPOSED IN SPACED PARALLEL RELATION. A JOINT MEMBER EXTENDS LENGTHWISE OF EACH CHANNEL AND IS ROTATABLY MOUNTED THEREIN, WHILE A RIGID CONNECTED STRIP EXTENDS ALONG EACH JOINT MEMBER AND IS JOINED TO IT. THE STRIPS PROJECT LATERALLY BETWEEN THE JOINT MEMBERS IN OVERLAPPING RELATION TO CLOSE THE SPACE BETWEEN THE FRAMES. THE CONNECTING STRIPS ARE HELD AGAINST LATERAL MOVEMENT ACROSS EACH OTHER. BY ROTAT- ING AT LEAST ONE OF THE FRAMES ON THE JOINT MEMBER THEREIN, THE ANGLE BETWEEN THE TWO FRAMES CAN BE CHANGED.
