Title (EN) LOCKING ARRANGEMENT PREFERABLY AT TELESCOPICALLY DISPLACEABLE RODS
(FR) AGENCEMENT DE BLOCAGE, DE PREFERENCE DE BARRES TELESCOPIQUES
Abstract:
(EN) Locking arrangement at telescopically displaceable rods, a first rod (1), which carries one sleeve (6) surrounding a second rod (2), the sleeve being adapted to clamp the second rod by means of an operating part which has the shape of a sliding piece (14) which by means of in pair arranged sliding surfaces (15) co-operate with sliding surfaces on a slide (12, 13) on the sleeve. The sliding surfaces diverge wedge shaped from each other. The slide (12, 13) consists of two parts (12, 13) each carrying one of the said sliding surfaces and being displaceable in relation to each other in a direction which is transverse to the longitudinal direction of the sliding surfaces between a position in which the second rod (2) is locked by clamping the element (6) about it by forcing the parts (12, 13) of the slide into a certain position for the sliding piece (14) and a position in which the second rod (2) is free to be moved in the element in that the sliding piece (14) is in its second position in which a wider part between the wedge shaped diverging sliding surfaces co-operate with the slide.
(FR) Dans un agencement de blocage de barres télescopiques, une première barre (1) porte un manchon (6) qui entoure une deuxième barre (2) et qui serre la deuxième barre au moyen d'un élément fonctionnel en forme de coulisse (14) pourvue d'une paire de surfaces coulissantes (15) qui coopèrent avec des surfaces coulissantes d'une coulisse (12, 13) agencée sur le manchon. Les surfaces coulissantes en forme de coin divergent les unes des autres. La coulisse (12, 13) comprend deux parties (12, 13) qui portent chacune une desdites surfaces coulissantes et qui sont mobiles l'une par rapport à l'autre dans un sens transversal à la direction longitudinale des surfaces coulissantes entre une position dans laquelle la deuxième barre (2) est bloquée lorsque l'on serre l'élément de serrage (6) autour d'elle, forçant les éléments (12, 13) de la coulisse à se mettre dans une certaine position de retenue de la coulisse (14), et une position dans laquelle la deuxième barre (2) peut se déplacer librement dans l'élément de blocage, la coulisse (14) étant dans sa deuxième position, dans laquelle une partie plus large, située entre les surfaces coulissantes divergentes en forme de coin, coopère avec la coulisse.
