Patent number: 5078198Abstract: A roller on which a curtain is rolled up has its respective ends closed by a washer and by a cap having two opposed recesses one inside and the other outside the roller. A first support in the outer recess supports one end of a threaded rod passing inside the roller and inserted at its other end, in a second support fastened to the washer. The threaded rod crosses two opposed bodies one of which is fixed and the other is movable, by virtue of its coupling with the threaded rod and the rod's axial rotation. Between the two bodies, a helical spring has its ends fastened to the same bodies, so that, the rotation of the roller causes the rotation of the movable body, which twists the spring, but at the same time moves along the threaded rod, thereby changing the longitudinal space available to the spring.Type: GrantFiled: May 7, 1990Date of Patent: January 7, 1992Assignee: Sunproject S.r.l.Inventor: Giovanni Tedeschi
