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 (2) monté mobile à rotation selon un premier axe de rotation (X1) entre une position engagée et une position désengagée avec l'élément mobile, - un organe de verrouillage (3) monté mobile à rotation selon un deuxième axe de rotation (X2) 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 (20) dont la came coopère opérationnellement avec l'organe de verrouillage pour le déplacer vers la position de libération ; La came de l'actionneur est une came cylindrique (21) tournant autour d'un axe de rotation (X4) orthogonal aux premier et deuxième axes de rotation.
