Elongated body e.g. round leg, assembling system for e.g. table, has intermediate piece comprising wings whose shape is such that imaginary surface surrounding external surface of wings is in conical shape

摘要

The system (1) has a plastic connection piece (2) provided with a conical interior cavity (3), and a plastic intermediate piece (4) locked in the cavity. The pieces are made of plastic material, where the plastic material of the connection piece is reinforced by glass fibers. The intermediate piece comprises wings (6) on a part of height of an external surface (5). Shape of the wings is such that an imaginary surface surrounding an external longitudinal surface (6b) of the wings is in conical shape, which is complementary to the conical shape of the cavity of the connection piece.
