Abstract

La presente invención se refiere a un sistema de enclavamiento de un dispositivo lineal de ajuste rápido y de bloqueo de una pieza móvil con relación a una pieza fija, este dispositivo lineal comprendiendo al menos un par de elementos de tornillo-tuerca llevados por una caja que coopera con las dos piezas fija y móvil y cuyo ángulo de tornillo es suficientemente elevado para que el rendimiento de la traslación hacia la rotación sea ligeramente positivo, el sistema estando provisto para poder enclavar el elemento giratorio del par de tornillo-tuerca después del ajuste de la posición de la pieza móvil, caracterizado en que los medios de enclavamiento de la tuerca comprenden: una porción de cilindro de enclavamiento provista de roscas interiores conjugadas a las roscas exteriores de la tuerca y, en estas dos series de roscas están realizadas acanaladuras complementarias, paralelas al eje del tornillo, la porción del cilindro de enclavamiento siendo solicitada por un órgano elástico contra un tope integral de la caja y sujetado con las acanaladuras de la tuerca bloqueando esta en rotación, el dispositivo estando entonces en descanso, un roscado estando formado en la caja y similar a las roscas de la tuerca, de manera que la tuerca puede girar en el roscado de la caja desplazándose axialmente en la misma y en las roscas del dispositivo de enclavamiento, cuando el cilindro de enclavamiento no está sujetado con la tuerca y, medios de mando manual que permiten desplazar axialmente al cilindro de enclavamiento para desacoplarlo de las acanaladuras de la tuerca y desenclavar está última a fin de permitirle girar en el roscado de la caja.
