ABSTRACT:
A device has removable, height-adjustable and positionable shelves. The device includes a pair of vertical struts inside of which suitable brackets of associated boards, can run. The vertical struts, have respective “racks” positioned in a back part of the struts, on which suitable toothed wheels are engaged that are located in a middle part of a rear end of each bracket. A lower end of each bracket a suitable toothed sliding back is located which, when the associated bracket is positioned in a normal horizontal position, i.e., at a right angle to the respective vertical strut, is engaged to a relative portion of the respective rack, but when the bracket is raised by being inclined upwardly at its front part, rotating around the associated toothed wheel, the sliding block is disengaged from the rack, thus being able to run freely vertically along the associated vertical strut. The device also has a related element for limiting the rotation and/or the support of the strut and suitable blocking elements capable of preventing any movement of the shelves.
