For both of the above situations there heretofore have been few satisfactory answers other than the construction of costly greenhouses or special greenhouse windows for homes.

Briefly, the portable greenhouse of this invention comprises a light-transmitting roof section of synthetic resin and a pair of end panels, one each removably attached to the ends o the roof section. The roof sect,ion comprises a panel having opposed end edges and opposed lateral edges with at least one fold line extending between the end edges and disposed between the lateral edges, the roof panel being folded along that fold line to form a roof section having open ends.

5 ¦incorporate an ultraviolet stabilizing ingredient to reduce
6 ¦degradation oE the plastic by sunlight.
7 The panels from which the greenhouse of Fig. 1 is ¦assembled are illustrated in Fig. 2. Since end panels 6 and ¦8 are substantially identical in configuration, only one of 10 ¦the panels 6 is illustrated. The roof panel 4 is defined by Il ¦opposed end edges 12 and 14 and opposed lateral edges 16 and 12 18. A central score line 20 extending between the end edges 13 ¦12 and 14 is disposed generally centrally of the lateral 14 ¦edges 16 and 18 and defines a fold line, preferably 15 bisecting the panel 4. A pair of intermediate score lines 16 22 and 24 also extend between edges 12 and 14 and are 17 ¦positioned on either side of and generally par~llel to the 18 ¦central sco~e line 20 and define additional f~ld lines. The 19 ¦central score line 20 facilitates folding of the panel 4 to ~0 ¦form the peak or ridge 26 of the roof section 2. Similarly, 21 ¦the intermediate score lines 22 and 24 facilitate the 22 add`itional folds 28 and 30 illustrated in Fig. 1. By 23 folding th~e roof panel 4 along these th~ee score lines, the 24 panel may be formed into a shape ~esembling a mansard roof 25 as illustrated in Fig. 1. In this configuration the roof 26 sec~ion thus comprises a pair of upper roof portions 32 and 27 34 and a pair of side portions 36 and 38.

These slots preferably are of about 3/8 11 ¦ inch width, or about twice the thickness of the roo~ panel 12 ¦ 4. Preferably, each of these end panels includes an 13 anchoring stake 48, suitably of galvanized steel rod, -- 14 ¦ inserted between a pair of adjacent internal ribs o~ the end 15¦ of panel. The diameter of the anchoring stake 4B is 16 desirably such that it will provide an inter~erence fit 17 within the channel provided by those adjacent ribs to retain 18 the stake ~rictionally in place.

19 The assembly of the greenhouse of this invention is ~0 illustrated in Fig. 1 and is achieved by first folding roof 21 panel 4 along fold lines 20, 22 and 24 into the mansard roof 22 shape illustrated. Then the bottoms of the end panels Ç and ; 23 8 are inserted through the respective slots 40 and 42, and 24 the side portions 36 and 38 of the roof section 2 are aligned to engage slots 44 and 46 in the end panels. At 26 ,that point, the end panels 6 and B are s1id into the 27 position illustrated in Fig. 1, with the roof scction 2 ` 28 maintained in its configuration by the straddled engagement 29 of the side p~rtions 36 with the slots 44 and 46 in the end 3 panels 6 and B.

Similarly, 7 ¦ while the end panels 6 and 8 are illustrated as being o 8 slightly less height than the peak 26 of the roof section,
9 ¦ such end panels could equally easily be dimension~ of equal or greater height than roof peak 26, and be only partially 11 ¦ received through the slots 40 and 42. However, by having 12 the end panels 6 and 8 of this slightly lesser height, a 13 small ventilation gap at each end is provided between the 14 top of the end panel and the peak 26 of the roof, a 15¦ frequently desirable feature.
16¦ When the portable greenhouse of this invention is 17¦ assembled as illustrated in Fig. lr it is quite rigid and, 18¦ due to its light weight, may easily be moved to any desired 19¦ location. ~owever, when used outdoors, this desirable light 2Q weight and portability reyuires anchoring of the structure 21¦ to prevent any disturbance by winds.
