Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
104 words
A portable greenhouse comprising a light-transmitting roof section comprising a roof panel of synthetic resin having opposed end edges and opposed lateral edges with at least one fold line extending between said end edges and disposed between said lateral edges, said roof panel being folded along said fold line to form said roof section having open ends, and a pair of end panels, one each removably attached to said roof section adjacent each said end edge thereof to at least partially close the ends of said greenhouse, portions of each said end panel being slotted to straddle portions of the adjacent said roof section.
Claim 2
Dependent Claim
104 words
A portable greenhouse comprising a light-transmitting roof section comprising a roof panel of synthetic resin having opposed end edges and opposed lateral edges with at least one fold line extending between said end edges and disposed between said lateral edges, said roof panel being folded along said fold line to form said roof section having open ends, and a pair of end panels, one each removably attached to said roof section adjacent each said end edge thereof to at least partially close the ends of said greenhouse, portions of each said end panel being slotted to straddle portions of the adjacent said roof section.
Claim 3
Dependent Claim
21 words
A portable greenhouse according to claim 1 wherein said roof panel score line is disposed generally centrally of said lateral edges.
Claim 4
Dependent Claim
75 words
A portable greenhouse according to claim 2 wherein said roof panel further includes a pair of intermediate fold lines extending between said end edges and disposed on opposite sides of and generally parallel to said centrally disposed fold line, whereby the roof panel may be further folded along the fold lines to form upper roof portions between the opposed intermediate fold lines and side portions between the fold lines and the respectively adjacent lateral edges.
Claim 5
Dependent Claim
25 words
A portable greenhouse according to claim 3 wherein said roof section comprises said roof panel folded and maintained in the shape of a mansard roof.
Claim 6
Dependent Claim
26 words
A portable greenhouse according to claim 1 wherein said roof panel may selectively be erected for use or folded flat along said fold line for storage.
Claim 7
Dependent Claim
44 words
A portable greenhouse according to claim 1 wherein said roof panel includes one slot adjacent each said end edge, each said slot extending transversely of said fold line, and wherein each said end panel is at least partially receivable through one of said slots.
Claim 8
Dependent Claim
52 words
A portable greenhouse according to claim 6 wherein portions of said end panels are slotted to straddle portions of said roof panel adjacent the ends of said slots, whereby the straddling engagement between the end panels and the roof panel may serve to retain the roof panel in a predetermined folded configuration.
Claim 9
Dependent Claim
23 words
A portable greenhouse according to claim 1 wherein said roof and end panels comprise double walled panels of extruded, internally ribbed synthetic resin.
Claim 10
Dependent Claim
14 words
A portable greenhouse according to claim 8 wherein said panels are formed of polypropylene.
Claim 11
Dependent Claim
75 words
A portable greenhouse according to claim 1 wherein the height of said end panels is less than the height of said roof section, whereby, upon attachment of the end panels to the roof section, the top of the end panels may be spaced below the roof section such that a gap may remain between the top of the end panel and the top of the roof section to serve as a vent for the greenhouse.
Claim 12
Dependent Claim
93 words
A portable greenhouse according to claim 1 wherein said roof section comprises a plurality of said roof panels aligned longitudinally along said fold lines, a portion of one end of each said panel overlapping the adjacent said roof panel, and which further comprises an additional said end panel which is attachable to said overlapping portion of each said adjacent pair of said roof panels to join said roof panels together, whereby the end panels attachable to the outermost end edges of the longitudinally outermost said roof panels define the ends of the greenhouse.
Claim 13
Dependent Claim
77 words
A portable greenhouse according to claim 11 wherein each said roof panel includes a slot adjacent each said end edge, each said slot extending transversely of said fold line, and wherein one of said end panels is at least partially receivable through each said slot, whereby, when adjacent roof panels are overlappingly aligned with their adjacent slots superimposed, the reception of one of the additional end panels therethrough may serve to lock the adjacent roof panels together.
Claim 14
Dependent Claim
38 words
A portable greenhouse according to claim 1 further comprising anchor means connected to each end panel for selective insertion into the earth, whereby, upon such insertion of the anchor means the greenhouse may be anchored to the earth.
Claim 15
Dependent Claim
37 words
A portable greenhouse according to claim 13 wherein said anchor means comprises a stake connected to each said end panel, whereby the greenhouse may be anchored to the earth by insertion of the stakes into the earth.
