CA 2584387

The invention relates to a threaded device (7) embodied in the form of an anti- twisting stop which is rotatably connected to a traction-pressure rod. The inventive device comprises two oppositely located ratchet devices which are connected by a body enabling to stop the traction-pressure rod in several rotational positions with a predetermined locking force and, afterwards, to release it each time. Said threaded device (7) facilitates the mounting of the traction-pressure rod by the fact that the twisting should not be locked by additional handling, thereby making it possible to carry out a fine adjustment without additional measures. The ratchet device (4) comprises, for example, two ratchet elements (10, 11) provided with one or several catch lugs (12) or a metal or plastic ring part on one side and a gear rim on the other side. In addition, said threaded device can be provided with a spring element and a second anti-noise threaded device.

L'invention concerne un dispositif fileté (7) réalisé sous forme d'un système de blocage en rotation, qui est raccordé, mobile en rotation, avec une barre de traction-compression. Le dispositif comprend deux dispositifs à encliquetage opposés, reliés par un corps, permettant d'immobiliser la barre de traction-compression en plusieurs positions de rotation, avec une force de verrouillage prédéterminée et de la libérer ensuite, à chaque fois. Ce dispositif fileté (7) facilite le montage d'une barre de traction-compression, du fait que la rotation n'a pas à être bloquée en recourant à des dispositions supplémentaires, ce qui permet d'avoir un réglage fin sans manipulations superflues. Le dispositif à encliquetage (4) comprend, par exemple, deux éléments d'encliquetage (10, 11) ayant un ou plusieurs nez de blocage (12) ou une bague partielle en métal ou en matière plastique sur un côté, et une couronne dentée sur l'autre côté. Ce dispositif fileté peut en outre être muni d'un élément à ressort et d'un second dispositif fileté anti-bruit.
