Connection method for frame profiles.

摘要

At the mitre-angle of a frame the abutting frame parts are fastened together by inserting the legs of an angle into box sections made on the respective frame parts and interposing between each leg and the respective box parts a clamping body having chamfered ends and finally rotating the clamping body so that it becomes wedged between the leg and the respective box parts to establish a clamping action which tightly connects the frame part and the angle together.
