Abstract

Movement assembly (20) for a gate (10) with folding doors, where such a gate is of the type comprising a first door (12) and a second door (14) configured to rotate around said first door (12), the movement assembly comprising: - a first lever (22) with a first end (22a) configured to be integrally hinged to the ground and an intermediate point (22b) configured to be operatively connected to the first door so that a rotation of the first door rotates such a first lever (22) in the opposite direction around the aforesaid first end (22a); - a slider (26) with a first end (26a) operatively connected to a second end (22c) of the first lever (22) and with a second end (26b) configured to be operatively connected to the second door, where such a slider (26) is configured to translate parallel to the extension plane of the first door so that a rotation of the first lever (22) around the aforesaid first end (22a) causes the second door to rotate in the same direction; - an arm (23) with a first end (23a) configured to be integrally hinged to the ground; - a second lever (24) with a first end (24a) hinged at the aforesaid second end (22c) of the first lever (22) and with an intermediate point (24b) hinged to a second end (23a) of the arm (23) so that a rotation of the first lever (22) around the first end (22a) pushes the second lever (24) towards the slider (26) with gradually decreasing speed during the opening phase of the first door.

Abstract

The present invention relates to a shatterproof gate (10), comprising: - a substantially rectangular movable wall (20) comprising at least one reinforcing cable (22) arranged along the longitudinal extension of the movable wall (20) and fixed at its ends (22a, 22b) at the side perimeter edges (20c, 20d) of the movable wall (20); - sliding means (21, 32) configured to allow the translation of such a movable wall (20) along its longitudinal extension axis and orthogonally to the ground plane; - a support structure (30) provided with a base configured to be fixed to the ground and with at least a first gap (31) for the passage of the movable wall (20) through the support structure (30); - a reinforcing structure (40) provided with a base configured to be fixed to the ground and with at least a second gap (41) adapted to accommodate one end of the movable wall (20) when the aforesaid shatterproof gate (10) is in the closed position. It is highlighted that the movable wall (20) comprises a blocking profile (25) fixed along a second side perimeter edge (20c) of the side perimeter edges (20c, 20d) and configured to block the translation of the movable wall (20) in the opening direction by mechanical interference with the reinforcing structure (40) around the second gap (41) when the shatterproof gate (10) is in the closed position and following a flexural deformation of the movable wall (20) with respect to its longitudinal extension axis.

Abstract

The present invention relates to an articulated sliding gate (10), comprising: - an articulated barrier (11), comprising at least two sections (11a, 11b) mutually articulated with hinging means with vertical axis (Y); - a plurality of rest and sliding wheels (12, 13) for the articulated barrier (11), said rest and sliding wheels (12, 13) being connected to a respective section (11a, 11b) each by means of a wheel-holder element (15) and by means of push means of the wheel-holder element (15) towards a sliding guide (14); - a sliding guide (14) for the rest and sliding wheels (12, 13). The push means of a wheel-holder element (15) comprise: - a bearing body (16) constrained to a lower portion of a section (11a, 11b); - hinging means (17) for the rotatable constraint of the wheel-holder element (15) with respect to the bearing body (16) around an axis of rotation (X2) parallel to the axis of rotation (X1) of the wheel (12, 13); - elastic push means (18) configured to push the wheel-holder element (15) to rotate around the axis of rotation (X2) so that the rest and sliding wheel (12, 13) moves away from the bearing body (16). The bearing body (16) is constrained to the lower portion of a section (11a, 11 b) with rotatable constraint means (80) with vertical axis.

Abstract

System (1) for driving a telescopic gate (40) with adjacent doors, comprising two juxtaposed cable-guide units (2, 3) each provided with a support structure (5) carrying a plurality of pulleys (7, 8) for guiding a cable (4) according to respective guide planes (W, Y, Z) and connectable to two respective juxtaposed lateral edges (41a, 41b) of a first door (41) in operating positions such that the pulleys guide the cable (4) along a loop-like trajectory around the first door (41). The support structure (5) of each cable-guide unit (2, 3) defines a through channel (6) extended according to a longitudinal direction (X) to receive the respective lateral edge (41a, 41b) of the first door (41), the corresponding cable-guide unit (4) carrying: two first pulleys (7) facing the corresponding juxtaposed sides of the through channel (6) and having the corresponding guide planes (W, Y) parallel to each other; two second pulleys (8) facing the bottom of the through channel (6), having the corresponding guide planes (Z) mutually coplanar and arranged so that each can return the cable (4) from a first pulley (7) to the other second pulley (8).
