Abstract
Hollow decorative tubing fabricated from thin walled metallic stock material, the stock material preferably being stock tubing. Tubing is cold worked to impart any desired design such as simulated bamboo having realistic culm and node characteristics. The tubing is preferably formed into serial or repeating sections, each characterized by the desired design. For simulated bamboo, a realistic node is worked into the tubing between adjacent sections. The invention may be regarded as a method for manufacturing the resultant elongate hollow decorative tubing or, alternatively, an article of manufacture such as a chair incorporating the resultant elongate simulated bamboo article.
Claims7
A method for manufacturing hollow decorative tubing used in furniture manufacture, comprising:
- providing hollow, cylindrical tubing having an outer surface;
- providing a plurality of complementing dies which include a negative of a desired external design for the tubing;
- positioning the dies about the perimeter of the tubing;
- rotating the dies while holding the tubing stationary in a fixed position, without axial or rotational movement;
- and
- contacting the dies on the outer surface of the tubing while the dies are in rotation and forcing the dies against the outer surface of the tubing to deform the tubing to the desired external design of the dies.
A method for manufacturing hollow decorative tubing used in furniture manufacture, comprising:
- providing hollow, cylindrical tubing having an outer surface, the tubing being formed from one or more of rolled ferrous metal, extruded aluminum, extruded aluminum alloys, metals, metal alloy, polyvinyl chloride, plastics, or combinations thereof;
- providing four complementing dies which include a negative of a desired external design for the tubing;
- positioning the dies about the perimeter of the tubing;
- rotating the dies while holding the tubing stationary in a fixed position, without axial and rotational movement;
- and contacting the dies on the outer surface of the tubing by cold work while the dies are in rotation and forcing the dies against the outer surface of the tubing to deform the tubing to the desired external design of the dies, the external design simulating a culm of natural bamboo.
