Abstract

Un sistema di bloccaggio per un armadietto con una molteplicità di cassetti (10) che include numerosi meccanismi a nottolino (25) ciascuno dei quali è associato ad un rispettivo cassetto. Ciascun meccanismo a nottolino ha un organo di ritegno (28), un organo di sollecitazione (30) ed una molla (48) che agisce sull'organo di sollecitazione. Tutti gli organi di ritegno sono montati su un albero (39) che è sollecitato tramite una seconda molla (61). Quando i cassetti sono chiusi, camme (16) sui cassetti agiscono contro gli organi di sollecitazione (30) e gli organi di ritegno (28) vengono spinti in posizioni non operative dalla seconda molla (61) così che qualsiasi cassetto può venire aperto. Se un cassetto viene aperto l'organo di sollecitazione (30) associato spinge l'organo di ritegno (28) e tutti gli organi di ritegno (28) rimanenti in posizioni operative nelle quali gli organi di ritegno (28) rimanenti si impegnano con le rispettive camme (16) ed impediscono così che i cassetti (10) rimanenti vengano aperti.A locking system for a cabinet with a multiplicity of drawers (10) which includes numerous pawl mechanisms (25) each of which is associated with a respective drawer. Each pawl mechanism has a retaining member (28), a stressing member (30) and a spring (48) which acts on the stressing member. All the retaining members are mounted on a shaft (39) which is stressed by a second spring (61). When the drawers are closed, the cams (16) on the drawers act against the stress members (30) and the retaining members (28) are pushed into the non-operative positions by the second spring (61) so that any drawer can be opened. If a drawer is opened, the associated stress member (30) pushes the retaining member (28) and all the remaining retaining members (28) into operating positions in which the remaining retaining members (28) engage with the respective cams (16) and thus prevent the remaining drawers (10) from being opened.
