  • Patent number: 6892743
    Abstract: A portable, modular greenhouse system that can be used to protect plants from harsh conditions. A green house according to the invention comprises a frame and a cover. The frame preferably comprises at least one panel constructed from a mesh of rigid wire, with a spacing between adjacent wires which is large enough to permit a gardener's hand to pass therethrough. The panels are preferably flexible and resilient, so that they return to their original shape after being bent. The cover preferably has sleeves formed in opposite edges thereof. Slats may be inserted into the sleeves, so that when the cover is on the frame the slats are located near the bottom of the frame, thereby weighing down the cover to keep it in place. The ends of the slats may be inserted through the mesh of the panels to further secure the cover to the frame.

The frame preferably comprises at least one panel constructed from a mesh of rigid wire, with a spacing between adjacent wires which is large enough to permit a gardener's hand to pass therethrough. The panels are preferably flexible and resilient, so that they return to their original shape after being bent. The panels may be manufactured in a plurality of standard sizes, so that they may be used to construct frames varying widely in size and shape. The frames are preferably able to be flattened for storage when the greenhouse is not being used. The cover preferably comprises a piece of light-transmitting plastic sized to fit over the frame. The shape of the cover will depend on the frame configuration. The cover preferably has sleeves formed in opposite edges thereof.
