Title (EN) RATCHET DEVICE,ESPECIALLY FOR AWNINGS
(FR) DISPOSITIF D"ENCLIQUETAGE, EN PARTICULIER POUR TENTES
Abstract: front page image
(EN)Ratchet device, especially for awnings, comprising two rotatably interconnected elements (2, 14), one element (2) having a portion formed as a sector of a ratchet wheel and the other element (14) being provided with a pawl (20) cooperating with the teeth (6) of the first element (2), and a movable member (23) which prevents resp. permits interengagement of the pawl and the teeth due to relative rotation in the elements. In a known device of this type, the movable member is a control tooth rotatably connected to the pawl. This demands a complicated construction which, when the parts are subjected to wear, may cause malfunction of the device. In the device according to the invention, the movable member (23) is arranged movably in relation to the second element (14) and is adapted to be moved upon influence of the frictional force which is brought about between the member (23) and the first element (2) during relative rotation of the element (2, 14).
(FR)Un dispositif d"encliquetage, en particulier pour les tentes, comprend deux elements lies de maniere rotative (2, 14), un element (2) ayant une partie formee comme un secteur d"une roue d"encliquetage et l"autre element (14) etant pourvu d"un linguet (20) cooperant avec les dents (6) du premier element (2), et un organe mobile (23) qui empeche, respectivement permet, l"engagement du linguet et des dents en raison de la rotation relative des elements. Dans un dispositif connu de ce type, l"element mobile est une dent de commande liee de maniere rotative au linguet. Ceci implique une construction compliquee, qui, lorsque les pieces sont soumises a une usure, peut provoquer le mauvais fonctionnement du dispositif. Dans ce dispositif, l"element mobile (23) est mobile par rapport au second element (14) et est adapte pour se deplacer sous l"influence de la force de friction qui vient s"exercer entre l"element (23) et le premier element (2) pendant la rotation relative des elements (2, 14).
