Abstract

Brazo de fuerza provisto de acoplamiento de enganche de un organo de autorregulación de su posición, generalmente paralelas dos a dos, dos de las cuales están constituidas por placas, dicho brazo siendo montado giratorio con relación a una estructura alrededor de un eje sensiblemente perpendicular a dichas placas y provisto del acoplamiento de enganche de un tornillo de autorregulación de su posición con relación a la estructura, dicho acoplamiento comprendiendo particularmente un dispositivo de articulación del tornillo y su soporte que permite un desplazamiento de este tornillo sensiblemente paralelo al desplazamiento del brazo con relación a la estructura, y que está constituido por prolongaciones de dichas placas más allá de las caras del brazo que son distintas de estas placas, caracterizado en que comprende un puntal tubular, cuya longitud está sensiblemente igual a la distancia entre dichas prolongaciones, que esta dispuesto entre estas prolongaciones y atravesado por un eje con unaextremidad roscada que coopera con un tuerca al mantenimiento del puntal entre las prolongaciones.
