DEVICE FOR CLOSING AND FIXING OF DOOR WITH SPRING MECHANISM

摘要

FIELD: mechanical engineering. SUBSTANCE: device has body containing cylindrical coil spring. Roller of this spring is seated on bracket. Detents for roller are made in the form of semi-circular flat springs. Spring-loaded rod which functions as lever serves as guide member for roller. One end of spring is made in the form of loop which accommodates spring-loaded rod. Body is made of tube which is square in cross-section. Spring mechanism of device for closing and fixing of door has body containing cylindrical coil spring, means for adjusting spring tension with adjusting slots made in end portion of tubular body which is of square cross-section. One end of spring is bent in the form of loop and embraces rod, other end of spring is made in the form of ring and can be repositioned in adjusting slots. EFFECT: higher efficiency. 2 cl, 5 dwg
