ABSTRACT:
Disclosed is a modular structural member comprised of a plurality of modular elements. Fully assembled, the modular structural member is particularly suitable for furniture, toys, or the like. Each modular structural member has two rods. Disposed on each rod may be hollow wooden beads. The beads may be in the form of turnings or other decorative elements. Each rod may be threaded in one direction: the first rod being threaded in the right hand or clockwise direction and the second rod being threaded in the left hand or counterclockwise direction. A coupling, also in the shape of a turning, is internally threaded to receive at one end the clockwise threaded rod and at the other end the counterclockwise threaded rod. At the opposed and oppositely threaded ends of the rods may be disposed appropriately threaded unions. By rotation of rods by the coupling, the entire assembly is rotated into respective unions to form a secure self contained member. The beads are held securely in place and sandwiched by the unions by means of the turnbuckle effect.
