摘要

Improvements in cold rooms and more particularly in the mechanisms that determine the hermetic closing of its doors, whose mechanism includes, in collaboration: a general armature in which the whole device is organized, a pair of suspended sheaves, with the possibility of turning and simultaneously perform reciprocating rectilinear displacements, bolts, a pair of antagonistic springs that exert permanent pressure on said rollers in a reciprocal approach to retain between them a shank with a tip that is substantially rhomboidal.
