Abstract
Abstract A patio structure is disclosed involving a canopy and a supporting structure made in modular units. One unit is generally rectangular in shape, and two other units are generally segmental in shape. An essential feature of the invention is that the end frames involved in each of the modular units are identical in size and shape, each frame having the contour of approximately one-quarter of an ellipse positioned with the longer semi-axis on the ground and the shorter semi-axis vertical.

Claim 1
Independent Claim
312 words
Patio canopy structure including a main roof sheet support comprising two generally identical end frames each comprising a beam having essentially the shape of one-quarter of an ellipse whose lower end at the apex of the longer ellipse axis is adapted to rest on the ground and whose upper end is at the distal end of the short ellipse axis, each of said beams comprising two substantially parallel upper and lower bars lying in the same vertical plane and filler structure lying in said vertical plane and having inclined portions rigidly secured near their opposite ends to said upper and lower bars respectively and providing a truss effect between said bars, each end frame including a vertical column L-shape in section rigidly secured to said distal end of its associated beam, each vertical column including two vertical planar beams at right angles to each other, each of these last named beams comprising an outer bar at the end of each leg of the L-shape and comprising a common inner bar at the apex of the L-shape, each of said vertical planar beams having a filler structure lying in the same plane as the associated bars and rigidly secured to said associated bars and providing a truss effect there, structure rigidly connecting the lower ends of said two end frames, a stringer rigidly connecting the upper ends of said two end frames, a plurality of sheet supporting roof ribs spaced between said end frames and rigidly connected at their opposite ends to said connecting structure and to said stringer respectively, said ribs having the same quarter-elliptical shape as the upper bars of said end frame beams, and a flexible roof cloth covering said canopy structure and secured to said end frames and to said structure rigidly connecting the lower ends of said two end frames and to at least some of said ribs.
