Abstract

Si descrive un saliscendi perfezionato per apparecchi di illuminazione, caratterizzato dal fatto di comprendere un gruppo frizionante costituito da una ruota dentata di frizione stretta tra un raccordo filettato accoppiato al perno centrale di rotazione del rocchetto di avvolgimento del cavo di sospensione del saliscendi ed una ghiera controdado filettata avvitata su detto raccordo, il quale avendo assieme al suo controdado 1a filettatura di senso opposto a quello di rotazione del rocchetto durante la discesa del cavo, mantiene sempre compressa e frizionata detta ruota dentata di frizione, così da autoregistrarla durante l'uso, compensando qualsiasi gioco che si creasse col tempo. Il saliscendi presenta inoltre un notevole numero di ulteriori perfezionamenti che lo rendono più economico, più facile da assemblare, di durata maggiore e di qualità uniforme nella produzione in serie.An improved ups and downs for lighting fixtures is described, characterized in that it comprises a friction assembly consisting of a clutch sprocket tightened between a threaded fitting coupled to the central rotation pin of the spool for winding the up and down suspension cable and a locknut nut threaded screwed onto said fitting, which having together with its lock nut a thread in the opposite direction to that of rotation of the spool during cable descent, always keeps said friction gear wheel compressed and frictioned, so as to self-register it during use, compensating any game created over time. The ups and downs also have a significant number of further improvements which make it cheaper, easier to assemble, longer lasting and of uniform quality in series production.
