ES235404U - Closure for registration boxes. (Machine-translation by Google Translate, not legally binding) - Google Patents

Abstract

Closing for register boxes, essentially characterized in that the cover of the box has in each of its vertices a hole perpendicular to it, through which passes a rod provided with a larger diameter head that has a conventional element for its rotation, said stem being partially wrapped by a helical spring that is supported by one of its ends on said head, while at its opposite end it does so in a step provided in the lower mouth of said hole in the lid, with the particularity that said rod, near its lower extremity, has a diametrical hole in which a transverse pivot acting as a locking element is housed, provided that the body of the box has at each corner with a lateral fin equipped with a through hole, endowed with diametrically opposed expansions in formal and positional correspondence with emerging limbs s of the transverse pivot, passing through said hole the lower end of said rod as well as its transverse pivot, so that by printing a rotation to the rod the ends of the transverse pivot stop being in correspondence with the lateral prolongations of the body orifice, producing thus the interlocking of the whole.
