Title (EN) STAY
(FR) ETAI
Abstract:
(EN) The stay comprises an external support-tube (1) in which can axially slide over a certain length a height-adjusting screw (3), axially actuated by a rotating nut (6a, 6b). To prevent said screw (3) from rotating when the nut (6a, 6b) rotates and from accidentally coming apart when the whole assembly is being manipulated, said screw (3) is made angularly integral with the external tube (1) by means (19a, 20a; 19b, 20b) which also prevent the screw (3) from having a too long and unwanted travel. Thus the screw cannot rotate when the nut (6a, 6b) is actuated while the external tube (1) is manually blocked and the screw (3) cannot accidentally come out of the external tube (1) when the whole assembly is manipulated.
(FR) L'étai est du type comprenant un tube-support extérieur (1) dans lequel peut glisser axialement sur une certaine longueur une vis (3) de réglage en hauteur, actionnable axialement par un écrou rotatif (6a, 6b). Pour empêcher une rotation de cette vis (3) lors de la rotation de l'écrou (6a, 6b) et son déboîtement accidentel lors de la manipulation de l'ensemble, des moyens (19a, 20a; 19b, 20b) solidarisent angulairement cette vis (3) du tube extérieur (1) et empêchent également une course trop longue et non souhaitée de la vis (3). Ainsi une rotation de la vis (3) ne peut pas se produire lorsqu'on actionne l'écrou (6a, 6b) tandis qu'on immobilise à la main le tube extérieur (1) et la vis (3) ne peut pas sortir accidentellement du tube extérieur (1) lors de la manipulation de l'ensemble.
