Abstract

Self-fastening bar for curtains and the like, characterized by being formed by three tubular sections, the central one of which is smaller in diameter than the other two, and has, at one of its ends, a transverse shaft with a spring or sharp-end clamp and divergent that appear outside and exceed its diameter, introducing this central section, at its opposite end, inside the smooth section of the other two, so that the divergent clamp is at the mouth of the latter and, pulling the first, forced introduction into the second to the desired depth, while the free end of the central section is introduced into the second section of greater diameter, in which depressions have been made that hold the base of an inner helical spring on which supports said free end of the central section, so that the total length of the bar, obtained with the forced introduction of the divergent clamp, is slightly greater than e the distance between the walls in which it is applied, producing the lace overcoming the resistance of the inner spring, until getting the ribs that finish off the lateral sections are fitted between said walls and held firmly in said position by the pressure of the inner spring, without the central section being able to move by embedding the ends of its clamp on the inner walls of the corresponding section, and being able to disassociate the assembly by actuating the side provided with the inner spring.
