Abstract

La boîte à ressort (1) de dispositif antichute comporte une bobine formée de deux flasques (3a,3b), sur laquelle est enroulé le rideau, tournant autour d'un arbre fixe (2), et un ressort de compensation (5) dont l'extrémité intérieure est fixée sur cet arbre (2) et dont l'extrémité extérieure (6) est fixée sur une barrette (13) mobile en translation dans des boutonnières (14) agencées à la périphérie des flasques (3a,3b). L'extrémité de la barrette (13) libère le doigt (10) d'un verrou basculant (8), articulé sur l'un des flasques (3a), en direction d'une roue crantée (7) solidaire de l'arbre fixe (2), en cas de rupture du ressort (5). Des éléments de sûreté (24,25) empêchent un déclenchement intempestif du dispositif antichute, notamment un levier de sûreté (24), muni de crans (29,30) coopérant avec la barrette (13), adjacent au verrou (8), ou une pièce de liaison (25) entre la barrette (13) et la bobine (3a,3b) jouant le rôle de « fusible ».
Application aux rideaux roulants motorisés ou mus à la main.

Figure imgaf001
The spring box (1) of the fall arrest device comprises a coil formed of two flanges (3a, 3b), on which is wound the curtain, rotating around a fixed shaft (2), and a compensation spring (5) of which the inner end is fixed on this shaft (2) and whose outer end (6) is fixed on a bar (13) movable in translation in buttonholes (14) arranged at the periphery of the flanges (3a, 3b). The end of the bar (13) frees the finger (10) of a rocking latch (8) hinged to one of the flanges (3a), in the direction of a toothed wheel (7) integral with the shaft fixed (2), in case of rupture of the spring (5). Safety elements (24,25) prevent an inadvertent release of the fall arrest device, in particular a safety lever (24), provided with notches (29,30) cooperating with the bar (13), adjacent to the lock (8), or a connecting piece (25) between the bar (13) and the coil (3a, 3b) acting as a "fuse".
Application to motorized or hand-driven rolling curtains.
