Title
(EN) RELEASE MECHANISM
(FR) MECANISME DE LIBERATION
Abstract
(EN)
A release mechanism for releasably joining two objects, such as straps, cables, ropes or the like, as well as two rigid members, such as pipes, tubing, beams, columns or the like. The mechanism is usable for releasing loads which are under tension and, in certain embodiments, also transmits compression and torsional forces. One mechanism includes a pair of pivoting plates (24, 26) connected to the ends of a bifurcated strap (90). The plates engage elongated surfaces on a root member (56) connected to an opposite strap (46). An indexing arrangement (52, 54, 82, 84) is provided to prevent relative sliding movement. The plates are biased for outward movement. Outward movement is prevented by releasable securement links or straps (94, 96). An alternative form of securement is provided in the form of a sliding enclosure (202). An alternative embodiment for flexible or rigid members is provided in the form of a central root (324) surrounded by outwardly pivoting leaves (306, 308, 310, 312). Pivoting members (334) connected to the leaves engage projections (332) on the root member. Alatch and release mechanism (342, 352) controls the movement of the leaves. A rope release mechanism has a pair of plates (412) received by a transverse root (430) connected to one rope (428). The plates are connected to the bifurcated end of the other rope (414). The root has a circumferential groove (444) which receives a rubber band (442) which releasably secures the bifurcations. The ends of the plates are releasably secured together.

Un mécanisme de libération permet de relier de manière libérable deux objets, tels que des sangles, des câbles, des cordes ou autres, ainsi que deux organes rigides tels que des tubes, des tubages, des poutres, des colonnes ou autres. Le mécanisme peut être utilisé pour libérer des charges qui sont sous tension et, dans certains modes de réalisation, également pour transmettre des forces de compression et de torsion. Un mécanisme comprend une paire de plaques pivotantes (24, 26) reliées aux extrémités d'une sangle bifurquée (90). Les plaques engagent des surfaces allongées sur un pied de retenue (56) relié à une sangle opposée (46). Un agencement pourvu de divisions (52, 54, 82, 84) est prévu pour empêcher un mouvement de coulissement relatif. Les plaques sont sollicitées pour se déplacer vers l'extérieur. Ce mouvement vers l'extérieur est empêché par des organes de liaison ou des sangles d'attache libérables (94, 96). Une forme alternative de fixation consiste en une fermeture coulissante (202). Un autre mode de réalisation d'organes flexibles ou rigides est prévu sous la forme d'un corpscentral (324) entouré par des tenons pivotant vers l'extérieur (306, 308, 310, 312). Des organes de pivotement (334) reliés aux tenons engagent des éléments faisant saillie (332) sur le pied de retenue. Un mécanisme de verrouillage et libération (342, 352) commande le mouvement des tenons. Un mécanisme de libération d'une corde possède une paire de plaques (412) reçue par un organe transversal (430) relié à une corde (428). Les plaques sont reliées à l'extrémité bifurquée de l'autre corde (414). L'organe transversal possède une rainure circonférentielle (444) qui reçoit une bande de caoutchouc (442) qui fixe de manière libérable les bifurcations. Les extrémités des plaques sont fixées l'une à l'autre de manière libérable.
