Abstract

La regolazione della distanza di una guida (20) del supporto scorrevole (10) di cassetti o ripiani di un mobile contenitore rispetto alla guida opposta viene ottenuta mediante una coppia di blocchetti parallelepipedi (30, 30') fissati sul dorso (23) della detta guida ed accoglibili entro opportune sedi (66), presentanti forma e dimensioni congruenti con quelle dei blocchetti, ricavate integralmente all'interno del primo componente (60) del distanziatore scatolare (80) del complesso di supporto, ogni blocchetto presentando un foro filettato passante (34) nel quale viene accolta una vite di manovra (35) dotata di una testa allargata (36) e, all'estremità opposta, di un intaglio (38) per cacciavite, accessibile dall'esterno, detta vite di manovra facendo riscontro su una protuberanza (72) ricavata all'interno del secondo componente (70) del detto distanziatore.(Fig. 1).
