Abstract

Abstract A series of panels are hingedly interconnected to form an enclosure. One panel is solid, one comprises a door frame and door, and the remaining panels have removable upper and lower sections. A domed roof is supported by radial tubes. The panel sections and roof are fabricated of plastic materials with the proper light transmission and air-impervious characteristics required for the plants. Benches for supporting the plants are secured to the insides of certain panels. The solid panel supports a heater, vent fan and thermostats.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 216 words
In a portable folding greenhouse, a plurality of rectangular flat panels each having side, upper, lower and horizontal central portions, means hingedly connecting the side portions of adjacent panels together so they may be either folded into a collapsed position or unfolded into an erect circular arrangement, each panel having removable upper and lower sections, with each section having a plastic insert with light transmitting but airimpervious properties, means anchoring the lower edges of said panels to the ground, one of said panEls being a door panel, a solid panel opposite said door panel, a heater and vent fan mounted on said solid panel, a low temperature-responsive control for said vent fan, radially arranged tubes removably connected to a central hub and having outer ends engaging a cable which runs through the upper portions of said panels, a cover on said tubes forming a roof, the cover continuously extending outwardly from said hub to said panels and being fabricated between the hub and panels entirely of a plastic material having light transmitting but air-impervious properties, a plurality of adjacent benches within said greenhouse, said benches having legs collapsibly connected to tops and inwardly angled edges so that the benches will interfit with each other, and brackets securing said benches to the side portions of said panels.
