ABSTRACT:
The present invention relates to a storage rack comprising upright posts resting on a ground, girders fastened in each case between a pair of posts, the girders being fastened to the respective posts in a line such that a roller conveyor supported by the girders is inclined at a slope with respect to the ground, there is a row of perforations arranged in each pair of posts, a mounting plate joined rigidly to the girder, the plate having at least one slotted hole arranged therein, and a fastening member thrust through a perforation and through a slotted hole whereby the girder is pulled firmly against the post, and the mounting plate is provided with a first toothing that extends in a direction perpendicular to the girder and co-operates with and, owing to the fastening member, remains engaged with a second toothing.
Preferably the second toothing is arranged in a separate retaining plate, through which the fastening member passes. Further it is advantageous that the first toothing in the mounting plate is arranged in at least one long edge of the slotted holes.
