Abstract
Disclosed are seating made from pressure vessels, such as cylindrical propane tanks with hemispherical ends, as well as methods for making this kind of seating. The methods involve cutting sections of the reclaimed tanks and placing those sections on a jig that establishes defined, ergonomic positions for seat and back portions of the furniture, and welding appropriate ends or supports to the sections to form the piece of furniture. The pieces of furniture are made without bending, rolling, or otherwise changing the shape of the cut sections from the pressure vessel.
Claims15
A method of making seating, comprising:
- cutting a preformed pressure vessel into seating parts using one or more templates to define the shape of the parts, the seating parts being of continuous curvature with defined radii of curvature derived from the pressure vessels;
- temporarily securing at least some of the seating parts to a jig, the jig including a curved seat position member and a curved backrest position member arranged generally perpendicular to one another, the seat position member being arranged such that (1) a highest point of the seat position member lies at about 17 inches from a ground level, and (2) an overall depth of a seat of the seating is about 20-21 inches with at least about 12-13 inches extending rearwardly of the highest point of the seat position member when the seat is placed on the seat position member such that a highest point of the seat curvature coincides with the highest point of the seat position member;
- and
- with the seating parts secured to the jig, securing the seating parts together into the seating.

A method of making seating, comprising:
- cutting a preformed pressure vessel having a cylindrical center section and hemispherical end sections into a curved seat portion and curved first and second supports, the seat portion having a line of maximum curvature;
- securing the cut seat portion onto a corresponding curved seat position member of a jig, the curved seat position member having a line of maximum curvature arranged about 17 inches from a ground level, such that the line of maximum curvature of the seat portion aligns with the line of maximum curvature of the seat position member, and such that an overall depth of the seat portion is about 20-21 inches with at least about 12-13 inches extending rearwardly of the line of maximum curvature of the seat position member;
- with the seat portion attached to the jig, attaching the first and second supports to the seat portion to assemble the seating;
- and
- releasing the seating from the jig.
