摘要

Improvements introduced in the construction of posters in mobile units, of the type comprising a rectangular frame made of metal profiles, which are characterized by the fact that stringers formed by slanted bars that meet at their upper end, whose bars are raised from the side rails thereof. They are joined in their middle part by a horizontal crossbar and from this crossbar there are some stones that go to one of the crosspieces of the frame, thus creating trestles arranged by opposing pairs on whose inclined sides the posters are hung; underneath the level of the frame and hung from the crosspieces thereof transverse hollow bars are arranged through which slides are moved which are capable of moving outside the area of the frame and carrying at their end a vertical spindle that rests on a flat plate; vertical bars arranged equidistantly at the periphery of the frame to mount on them a skirt trim that covers the lower part thereof; lateral wheel axle that rests on leaf springs and a front projection on the end of which the brake device itself is mounted and in connection with that of the tractor vehicle.
