Title (EN) ROTATIONALLY SELECTABLE LOCK OF SHAFT TO HOUSING
(FR) VERROUILLAGE SÉLECTIONNABLE PAR ROTATION D’UN ARBRE SUR UN BOÎTIER
Abstract:
(EN) A rotationally selectable lock apparatus includes an outer element having a plurality of locking pins that are radially spring loaded to extend and retract through the outer element. An inner element is substantially encircled by the outer element and coupleable to a driveshaft. The inner element is configured to cause the plurality of locking pins to retract through the outer element in response to the driveshaft rotating in a first direction and extend through the outer element to engage a housing in response to the driveshaft rotating in a second direction, opposite to the first direction.
(FR) La présente invention concerne un appareil de verrouillage sélectionnable par rotation qui comprend un élément externe ayant une pluralité de broches de verrouillage qui sont radialement sollicitées par ressort pour se déployer et se rétracter à travers l’élément externe. Un élément interne est sensiblement entouré par l’élément externe et peut être couplé à un arbre d’entraînement. L’élément interne est configuré pour amener la pluralité de broches de verrouillage à se rétracter à travers l’élément externe en réponse à la rotation de l’arbre d’entraînement dans une première direction et à se déployer à travers l’élément externe pour mettre en prise un boîtier en réponse à la rotation de l’arbre d’entraînement dans une deuxième direction, opposée à la première direction.
