Abstract

A CLOSURE MECHANISM, comprising the set consisting of two groups of separate but connectable pieces, the first of which groups consists of a relatively stationary base piece, carrying inside another piece of closure while the second group consists of a main piece carrier of a half-hollow projection, in the manner of a latch, inserted into a lateral opening facing the base part of the first group, with the characteristic feature that the said closing piece, sliding and guided inside the base part is carrier of a protruding appendage and has hinged at a point thereof a locking lever occupying two stable angular positions determined and controlled by a key external to the assembly, so that, on the one hand, the appendix in question is located so that during the sliding of the closing piece to its closing position, it is capable of penetrating into the hollow of the middle projection of the main piece of the second group locking the latter if the projection in question has been introduced into the side opening of the base part of the first group and, on the other hand, the hinged locking lever has an angular projection that, when the closure piece is found sliding in its closed position, it is in turn capable of adopting a blocking position for which said projection abuts a fixed part of the base part preventing the relative sliding of the closing part with respect to the base part, as well as another unlocking position for which said projection does not abut with said fixed part, leaving free to slide said closing part.
