Abstract
Abstract A hothouse has at least two elongate cultivation corridors beside each other for a series of cultivation wagons which are transversely shiftable along the cultivation corridors in order, during the cultivation cycle, to be progressively moved around in the hothouse. A plant treatment area is provided outside the extent of the cultivation corridors for the starting, care and harvesting of the plants cultivated on the cultivation wagons. Transfer wagons are provided for transfer of the cultivation wagons between the elongate cultivation corridors and also for removal of optional cultivation wagons to the plant treatment area, the transfer wagons having a corridor section for receiving the cultivation wagons during their transfer from one cultivation corridor to the other and during their transfer to and from one cultivation corridor and the plant treatment area. The transfer wagons are reciprocal along transfer corridors which extend transversely of the cultivation corridors. The elongate cultivation corridors may be disposed in hothouse sections lying beside each other and interconnected via transfer areas which may, at the same time, serve as plant treatment areas.

Claim 1
Independent Claim
94 words
A hothouse, primarily intended for the cultivation of tomatoes or lettuce, comprising (a) at least two corridors, the ends of one corridor being adjacent the ends of the other corridor, (b) a plurality of cultivation wagons in adjacent relationship in each said corridor, (c) transfer means at the adjacent ends of said corridors for transferring cultivation wagons from one corridor to a corridor adjacent thereto, (d) a plant treatment area adjacent to at least one said corridor, and (e) transfer means for transferring cultivation wagons between said plant treatment area and said adjacent corridor.
Claim 2
Dependent Claim
94 words
A hothouse, primarily intended for the cultivation of tomatoes or lettuce, comprising (a) at least two corridors, the ends of one corridor being adjacent the ends of the other corridor, (b) a plurality of cultivation wagons in adjacent relationship in each said corridor, (c) transfer means at the adjacent ends of said corridors for transferring cultivation wagons from one corridor to a corridor adjacent thereto, (d) a plant treatment area adjacent to at least one said corridor, and (e) transfer means for transferring cultivation wagons between said plant treatment area and said adjacent corridor.
Claim 3
Dependent Claim
30 words
The hothouse of claim 1, said corridors having rails for guiding the wheels of said cultivation wagons, at least one said transfer means having rails alignable with said first-mentioned rails.
Claim 4
Dependent Claim
12 words

Claim 5
Dependent Claim
12 words
The hothouse of claim 1, said corridors being in adjacent, parallel relationship.
Claim 6
Dependent Claim
17 words
The hothouse of claim 1, said plant treatment area being intermediate the ends of one said corridor.
Claim 7
Dependent Claim
51 words
The hothouse of claim 1, said hothouse having two additional corridors in spaced parallel relationship to said first two corridors, said plant treatment area being intermediate said first mentioned corridors and transfer means for transferring cultivation wagons between at least one of said first corridors and one of said additional corridors.
Claim 8
Dependent Claim
35 words
The hothouse of claim 1, said hothouse having at least two additional corridors substantially in line with said first two corridors, said plant treatment area being intermediate said first mentioned corridors and said additional corridors.
Claim 9
Dependent Claim
29 words

Claim 10
Dependent Claim
41 words
The hothouse of claim 8, said plant treatment area having personnel carrier means therein, and means for raising and lowering and longitudinally or transversely moving said personnel carrier in relation to the said wagon received on said first mentioned carrier means.
Claim 11
Dependent Claim
46 words
The hothouse of claim 1, and a transfer area at one end of said corridors, said first mentioned transfer means comprising a wagon and comprising means for transferring said cultivation wagons on said last mentioned wagon to and from a said corridor and said transfer area.
Claim 12
Dependent Claim
15 words
The hothouse of claim 10, and partition means between said transfer area and said corridors.
Claim 13
Dependent Claim
19 words
The hothouse of claim 10, and means in said transfer area for processing material carried by said cultivation wagon.
Claim 14
Dependent Claim
70 words
The hothouse of claim 1, said corridors being adjacent and parallel, said hothouse having two additional corridors in spaced parallel relationship to said first two corridors, a first section of said hothouse containing said second mentioned corridors, a cultivation section between said first and second sections of said hothouse, and transfer means for transferring cultivation wagons between at least one of said first corridors and one of said second corridors.
Claim 15
Dependent Claim
43 words
The hothouse of claim 1, said hothouse comprising means for emitting heat beneath at least some of said cultivation wagons, cultivation trays carried by said cultivation wagons, and gaps between said cultivation trays for the upward passage of heat past said cultivation trays.
Claim 16
Dependent Claim
41 words

Claim 17
Dependent Claim
40 words
The hothouse of claim 1, said corridors being in one section of said hothouse, said transfer means and said plant treatment area being in other sections of said hothouse, and said corridor containing section being longer than said other sections.
Claim 18
Dependent Claim
40 words
