Abstract (en)
Braking mechanism for controlling and attenuating the roll-up speed of a roll fly-screen which has on the one end a spring for its automatic roll-up. The mechanism is mounted internally on the fly-screen axis (1) and is comprised by a nut (2) which rotates along with the axis (1) and is forced into an axial movement on the screw thread of the stable screw (3). The nut's movement causes the length variation of the spring (4) and the development of friction between the friction element (5) and the ratchet lock (6) as well as on the surface between the ratchet lock (6) and the friction element (7). During the extension of the fly-screen, the ratchet lock allows the free rotation of the fly-screen axis (1) creating braking only during its roll-up stage. The initial position of the nut (2) in relation to the spring determines both its initial prestress and the braking force that would be developed at the friction elements.
