Abstract

L'invention est relative à un boîtier d'accrochage pour retenir sélectivement en position un élément mobile tel qu'un atterrisseur ou une trappe, le boîtier comportant un corps portant : - un crochet monté mobile à rotation selon un premier axe de rotation entre une position engagée et une position désengagée avec l'élément mobile, - un organe de verrouillage monté mobile à rotation selon un deuxième axe de rotation parallèle au premier axe de rotation entre une position de blocage du crochet en position d'engagement et une position de libération du crochet, - et au moins un actionneur à came dont la came (21) coopère opérationnellement avec l'organe de verrouillage pour le déplacer vers la position de libération. Dans l'actionneur, la came de l'actionneur est reliée en rotation à deux roues libres (33, 34), elles-mêmes entraînées par des moteurs électriques (35, 36) respectifs.The invention relates to a hooking box for selectively retaining in position a movable element such as a landing gear or a hatch, the box comprising a body carrying: - a hook mounted movable in rotation about a first axis of rotation between a engaged position and a disengaged position with the movable element, - a locking member mounted movable in rotation along a second axis of rotation parallel to the first axis of rotation between a position of locking the hook in the engaged position and a release position of the hook, - and at least one cam actuator, the cam (21) of which cooperates operationally with the locking member to move it to the release position. In the actuator, the actuator cam is rotatably connected to two free wheels (33, 34), themselves driven by respective electric motors (35, 36).
