PURPOSE: To improve assembly workability by fixing a joiner having an approximately equilateral triangular cross section and a hinge at an apex section at the end section of a lever forming a framework, etc., connecting the mutual hinges by pins and combining the lever at various angles.
CONSTITUTION: A joiner 3 having inclined planes 23 and 24 and a hinge 5 at the apex section of the joiner 3 is fixed at the end sections of levers 1, 2 forming a framework, a frame, etc. The adjacnet hinges 5 are combined mutually, and connected by a pin 8 consisting of a bolt, etc., thus forming a hinge 30. A plurality of the levers 1, 2 can be connected by forming straight lines, right angles, T shapes, crosses and arbitrary angles, and formed in a free shape on a design. Accordingly, the levers can easily be mounted at a free angle.
