摘要

The shelf (15) has an upper face provided with compartments forming housing for tools. A lower face (17) has a rotation unit (24) rotating around a transverse axis. A locking arm (30) is projected from a flank (20), and defines a lateral surface (31) and a horizontal surface (32) that is vertical and parallel to the transverse axis. A wall (29') is projected from the lower face on a lower portion (23) at a front end of the shelf, where the wall defines a front housing (34). The rotation unit has hooks projecting from the lower face around the transverse axis and a cutout (26) in the flank. An independent claim is also included for a ladder.
