Abstract (en)
Improved grating frame consisting of an external strip (1) which defines a closed and hollow figure on which male appendages (7) and female appendages (8) are located with the conditions of being symmetrical with respect to a longitudinal axis and that for each male appendage (7) there is a female appendage (8) situated in symmetrical position so that by turning the body 180 degrees said part coincides with another identical one in order to form the grating frame. In addition to the perimetric strip (1) there exist interior strips (2) also distributed in a symmetrical manner with respect to the symmetry axis of the body. <IMAGE>
