Improvements to Venetian blind apertures

These improvements involve the use of parts (4 and 5) designed to be mounted as an option on some of the sides of the blind aperture, forming respectively stops for the mounting in the light of a cover (3) without an insulator and a cover (3) with an insulator (31). The part (4) is of a "U" shape, with flanges (41 and 42) of different length, with teeth inside (43) to hold them on the tabs (12 and 13) of the side covers (1) of the frame, the larger flange having a step (44) to support the cover (3) without an insulator. The parts (5) have an "L" shaped cross section with arrow head feet (53) for mounting under pressure in the channel (21) formed in the lower profile (2) of the opening aperture.

Estos perfeccionamientos contemplan la utilización de unas piezas (4 y 5) destinadas a montarse opcionalmente sobre algunos de los laterales del marco del registro, conformando respectivamente unos topes para el montaje a luz de una tapa (3) sin aislante y de una tapa (3) con un aislante (31). La pieza (4) presenta una configuración general en "U", con unas alas (41 y 42) de diferente longitud, provistas de unos dientes interiores (43) para su retención sobre los apéndices (12 y 13) de las tapetas laterales (1) del marco, presentando el ala mayor un escalón (44) para el apoyo de la tapa (3) sin aislante. Las piezas (5) presentan una sección general en "L" con unas patillas (53) en punta de flecha para su montaje a presión en el canal (21) definido en el perfil inferior (2) del marco del registro.
