Abstract
Abstract Apparatus for the hydroponic cultivation of vegetables including substantially horizontal tubular structures for holding therein transplanted plants. The tubular structure is made of a troughlike member and lid members of elastically flexible material, yieldably closing the troughlike member and clamping the plant between contacting edges of the lids. The tubular structure is removable suspended on vertically movable vertical ropes guided by a system of pulleys.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
106 words
An apparatus for the hydroponic cultivation of vegetables including substantially horizontal tubular structures for holding therein transplanted plants, pipe means connected with said tubular structures for feeding therein a nutrient solution for the plants and adjustable supporting means for adjustably supporting said tubular structure, wherein, according to the improvement, each tubular structure comprises a trough-like member of substantially rigid material having two longitudinally extending substantially parallel, spaced apart edges, and resiliently deformable lid members secured on said edges, the lid members of each tubular structure having lip-like free ends thereof resting against each other thereby to cover said troughlike members and yieldably hold the plants therebetween.
Claim 2
Independent Claim
106 words
An apparatus for the hydroponic cultivation of vegetables including substantially horizontal tubular structures for holding therein transplanted plants, pipe means connected with said tubular structures for feeding therein a nutrient solution for the plants and adjustable supporting means for adjustably supporting said tubular structure, wherein, according to the improvement, each tubular structure comprises a trough-like member of substantially rigid material having two longitudinally extending substantially parallel, spaced apart edges, and resiliently deformable lid members secured on said edges, the lid members of each tubular structure having lip-like free ends thereof resting against each other thereby to cover said troughlike members and yieldably hold the plants therebetween.
Claim 3
Dependent Claim
24 words
An apparatus according to claim 1, wherein said lid members have forked rims adapted to receive therein said longitudinal edges of said trough-like member.
Claim 4
Dependent Claim
20 words
An apparatus according to claim 1, wherein said lid-members have removable fastening means for pressing the lips against each other.
Claim 5
Dependent Claim
106 words
An apparatus according to claim 1 wherein said adjustable supporting means comprise vertically movable rope-like elements, vertically extending and arranged at regular intervals along said tubular structures, bracket-like wire elements having each a semicircular portion in which said trough-like members are received, said bracket-like wire elements being arranged at regular intervals along said tubular structures and having each an extension of said semi-circular portion thereof terminating with a hook shaped end engaging the respective rope-like element, V-antenna-like wire elements arranged above said bracket-like wire elements at regular intervals, said V-antenna-like elements having at least one end thereof hook shaped and engaging the respective vertical rope-like element.
Claim 6
Dependent Claim
22 words
An apparatus according to claim 4, further comprising a net supported on said V-antenna-like elements and adapted to assume the V-shape thereof.
