Variable geometry frame without central pillar - comprises square arms with ferrules at ends fitting, at top, in central piece slots, and at bottom resting on ground

摘要

The frame, without a central pillar, comprises square frame arms (3) acting as pillars and carrying beams. There is a central piece (1) which acts as repository for the frame arms and a horizontal pivot. The central fixing piece has fixing slots, which allow choosing the desired angle, where U ferrules (2) at the arm upper end are seated. At the other end of the arms (3), resting on the ground, are second ferrules (4) which provide vertical pivoting. USE/ADVANTAGE - Frame, not having a central pillar, which may be erected on variable ground surfaces and a have a variable height. Can be mounted rapidly.
