Abstract

See full text

A folding chair provided with 8 rods, 4 of which stand vertically a distance apart defining the four corners of the chair and four of which are diagonally crossed and pivotly secured to each other near their midpoints. The lower end of each diagonal rod is connected to the lower portion of a vertical rod and the upper end of the diagonal rod is connected to the upper portion of the vertical rod located at the corner diagonally opposite the first vertical rod. A seat bottom comprised of flexible material and two bracing rods is supported at four corners where the upper ends of the diagonal rods meet the vertical rods. Arm and back supports of a flexible material are supported by portions of the vertical rods extending upward beyond the seat level. Each vertical rod is connected to a diagonal rod in two locations. In the first embodiment, one connection is a releasable joint and the other connection is pivoted joint. In the second embodiment, two pivoted joints on each vertical rod are allowed to move towards and away from each other by means of an expanding and contracting rod. Both of these constructions permit the chair to be collapsed into a compact linear storage configuration in which the diagonally crossed rods pivot into a position alongside one another while the vertical rods assume a position alongside the diagonal rods.
