Title (EN) IMPROVEMENTS IN OR RELATING TO STAIRLIFTS
(FR) PERFECTIONNEMENTS APPORTÉS OU SE RAPPORTANT À DES MONTE-ESCALIER
Abstract:
(EN) The invention describes a mechanically-based arrangement for locking a stairlift chair relative to a stairlift carriage in the event of a failure within the drive that is provided to maintain the chair level as the stairlift is in operation. The arrangement uses inter-engaging components that are engaged and dis-engaged in timed relationship to rotation of the levelling motor. At all times at least one set of inter-engaging components are engaged.
(FR) La présente invention concerne un agencement mécanique pour verrouiller une chaise de monte-escalier par rapport à un chariot de monte-escalier en cas de défaillance à l'intérieur de l'entraînement qui est prévu pour maintenir le niveau de la chaise lorsque le monte-escalier est en fonctionnement. L'agencement utilise des composants de mise en prise mutuelle qui sont mis en prise et désaccouplés en relation synchronisée avec la rotation du moteur de mise à niveau. À tout moment, au moins un ensemble de composants de mise en prise mutuelle est mis en prise.
