Abstract

Improved rack for the elevation of a compass tube for the closing of aeration of greenhouses, characterized in that it is constituted by a bar, whose profile has the shape of a t, whose lateral fins constitute effective reinforcements of its structure, and the toothing of the rack, is practiced on the edge of the partition perpendicular to the fins, so that the operations of opening or closing the enclosure of the aeration of the greenhouse, will not be hindered by the absolute guarantee that the rack, will not suffer warps or folds the violent action of winds on the open enclosures, at which time the rack is in its position of maximum height and greater distance from the gear pinion.
