Publication number: 20240125159Abstract: Telescopic assembly with locking device in retracted configuration A telescopic assembly (10) includes: a first (12) and a second (14) body; the second body comprising a rod capable of sliding into the first body between extended and retracted configurations; and a device (18) for locking in the retracted configuration. The locking device includes a ferrule (60) positioned on the rod, the ferrule comprising an internal stop (80) and the first tubular body comprising a counter-stop (34), capable of cooperating to lock the first tubular body and the ferrule. The ferrule is locked in translation relative to the second body (14) and rotatable around said second body, between an unlocked position, allowing the sliding of the second body into the first body (12), and a locked position retaining the second body in the retracted configuration.Type: ApplicationFiled: September 20, 2023Publication date: April 18, 2024Applicant: LISI AEROSPACEInventors: LAURENT RENARD, BASTIEN BELLAVIA

Patent number: 11384575Abstract: The invention involves a keeper (20) to interact with a bolt (16) of a lock (10); The keeper includes a bracket (22) for attachment to a structure, and a keeper rod (24) secured to the bracket, the keeper rod extending from one surface (27) of the bracket. In the keeper, a shaft (32) is attached to the bracket and can rotate freely relative to the bracket such that it extends in a longitudinal direction (X); a blade (40) is mounted on the shaft (32) on one side of the bracket near the keeper rod in such a way as to always rotate along with the shaft; an angular position indicator (46) is also mounted so as to always rotate along with the shaft; the blade being so positioned that it can be rotated by the latch when the latch hooks on to or releases from the keeper rod, and the angular position indicator (46) being capable of indicating the angular position of the blade. The invention is for example intended to be used on an aircraft door such as that of a helicopter.Type: GrantFiled: July 11, 2018Date of Patent: July 12, 2022Assignee: LISI AEROSPACEInventors: Bastien Bellavia, Boris Hummel

Patent number: 11352814Abstract: The present invention relates to a locking device (10), comprising a threaded rod (12) and a tapping tube (14), which are movable relative to each other. An outer surface of the tube includes a first anti-rotation form. The device further comprises: a locking sleeve (16) positioned around the rod and comprising a second anti-rotation form (60, 62) capable of being assembled to the first anti-rotation form; and an elastic element (18) connected to the locking sleeve. In a locked position, the first (38, 40) and second (60, 62) anti-rotation forms are assembled; and in a release position, said anti-rotation forms are axially spaced apart, whereby the tube is free to rotate relative to the sleeve.Type: GrantFiled: March 11, 2020Date of Patent: June 7, 2022Assignee: LISI AEROSPACEInventors: Yannick Astier, Bastien Bellavia, Boris Hummel

Patent number: 9297401Abstract: The invention relates to a quick-release fastener (100) of the ball-pin type, consisting of a tubular body (102) provided with a radial opening (108), an enlarged head (104), a rod (112) that can move axially within the body and through the head, a ball (110) capable of moving radially between a released position in which it rests in a reduced cross-section (132) of the rod (112) inside the body and a locked position in which it protrudes radially beyond the body through the radial opening (108), and a lever (114) that pivots about a pin (118), which lever includes at least one cam surface (142) that is in contact with the head. The rotational actuation of the lever draws the rod toward the head and causes the ball to move into the released position.Type: GrantFiled: October 17, 2014Date of Patent: March 29, 2016Assignee: LISI AEROSPACEInventors: Sebastien Langlais, Vincent Defrance, Bastien Bellavia
