Abstract

Brake device for ropes, especially intended for locking, in the position that in each case is of interest, of the flexible steering rods of the rolling shutters, characterized in that it comprises a body provided with fixing means to the vertical surface of interest, which forms a parallelepiped cavity sensibly elongated, arranged to be installed with its horizontal axis and equipped in its upper and lower walls with two central openings through which it is traversed, with considerable clearance, by the tie that is to be governed; inside which cavity is housed an independent piece, of elongated shape, endowed with a rounded central notch, with a chamfered edge, which fits approximately in that in its length, and presents, with respect to the section transversal, a clearance that allows it to perform certain movements of ascent and descent and of rotation; everything so that when the rope is located in the vertical position, fitting in the central notch of the internal part, it can slide freely, with minimal friction and in any direction, with respect to the whole, while it is enough to print it a lateral movement, displacing it from said notch, so that it is wedged against the expressed piece, being blocked with all certainty thanks to the impulse of twist that it undergoes, as a consequence of the tendency of the rope to slide upwards, because of the weight of the wound portion of the blind.
