Detachable frame for fixing and tensioning e.g. canvas on table utilized by painter, has hole permitting screwing of end screw to permit longitudinal displacement of each post with respect to element and separate posts from one another

摘要

The frame has a metal face (4), and threaded holes (2) formed transversally with respect to a longitudinal axis of straight or bent hollow posts (1) at the level of a projecting part (1a), where n is an integer greater than/equal to three and the frame is in polygonal, circular or oval shape. Each hole permits screwing of a conical end screw (6) that is displaced in axial translation by exerting force on a contact face (3a) of an arm of a connection element (3), to permit longitudinal displacement of each post with respect to the element and separate the assembled posts from one another. The posts and the connection element are formed from different materials such as wood, natural agglomerated materials such as wood chips or filler woods, synthetic materials, aluminum alloy or derived materials.
