ABSTRACT:
A folding tubular frame structure and subcombination for use in a folding beach and deck chair and in a folding table. The subcombination comprises a cast or machined joint member having the concentric combination of a male insert or stub member and, surrounding said member, an annular groove seat. A tubular strut such as a chair leg fits snugly into the seat and telescopes loosely over the male insert member. A connector member is pivotally pinned into a slot in the end of the stub and receives one end of a tension spring at the outboard end thereof. The tension spring runs through the tubular strut and is fastened to an insert portion of a terminal member such as a foot. The tension spring resiliently urges the foot into the outboard end of the tube and further resiliently urges the tube into the annular slot. However, the spring permits the tube to be pulled from the slot and rotated along with the connector member and spring into a folded position.
