Problems solved by technology

However, these systems either require the use of mechanical fixing members on the relevant building opening frame, which means that the construction process is relatively time consuming, or require the modification of the opening frame for the relevant enclosure structure
These lattices are generally heavy and difficult to manufacture, and they contain relatively complex locking systems, especially those disclosed in FR2647497, FR2661449

Embodiment Construction

[0065] shown in Figure 1A The protective device of the present invention comprises a single extendable rod 2 to which three rigid slats 4 are detachably fixed approximately in their middle by clips (not shown) and perpendicular to the Extendable rod2. The separation distance 5-1 between the three slats 4 provides a gap in the barrier 5a formed by the set of three rigid slats 4 . The distance 5-1 between two consecutive slats is less than or equal to the width of the slats.

[0066] Each slat 4 is formed by two complementary slat elements 4a, 4b, one of which is nested within the other and can slide longitudinally in said other. exist Figure 1A Among them, the plug-type component 4b protrudes from both ends of the socket-type component 4a. The user may be provided with plug-type elements 4b of various lengths in order to configure the plug-type elements based on the size of the passage opening to be blocked with the device of the invention.

Abstract

The invention relates to a self-contained protective device (1, 1a-1b) for temporarily blocking passages (10), such as corridors, doors or windows, characterized in that it comprises at least one longitudinally extendable rod (2, 2a-2b ), preferably a telescopic rod configured to be actuated by an actuator (3) to extend, and the rod is configured to be detachably locked in its extended state in two Between wall surfaces (10a, 10b), called locking surfaces, said extendable rod supports a blocking element, preferably a plurality of blocking elements (4), to form a protective barrier (5) blocking said passage , 5a, 5b), wherein said one or more blocking elements are preferably detachably fixed.

Description

technical field [0001] The invention relates to a self-contained protective device for temporarily blocking passages, such as corridors, doors or windows. Background technique [0002] Various systems of detachable intruder-resisting gratings are known for openings in buildings, and there are even systems designed to prevent people from falling out of windows. However, these systems either require the use of mechanical fixing members on the relevant building opening frame, which means that the construction process is relatively time consuming, or require modification of the opening frame for the relevant enclosure structure. These lattices are generally heavy and difficult to manufacture, and they contain relatively complex locking systems, notably those disclosed in FR2647497, FR2661449. [0003] Roller gate type systems have also been proposed, notably in FR2360073, WO94 / 20723 and FR2814230. However, these systems also require the use of mechanical fixing members on the ...
