FASTENERS FOR FRIEZES OF RAILINGS, GRATINGS AND THE LIKE

摘要

Fasteners for friezes (7, 9) of railings, gratings and the like are constituted of annular bodies from elastic material, integral (1) or sectional (1'), on whose external (5) and internal (2, 3) surfaces parallel protrusions (10, 10') are present, which are sequentially arranged in the form of annular saw-tooth indentations that are inclined, the external ones (10) in a direction, the internal ones (10') in the opposite direction with respect to the symmetry axis (11) of said annular bodies. They are pressure-interposed between the peripheral surfaces of holes (6 and/or 8) of friezes, and the external surfaces of the coupling standards (4), with the indentations (10, 10'), oriented in such a way as to facilitate the pressure-coupling and to prevent the subsequent detachment attempts.
