PREFERRED EMBODIMENT OF THE INVENTION

(15) In the example of embodiment shown in FIGS. 1 to 9, the system for closing through openings has a quick opening door provided with a vertically moveable flexible panel (1), connected to a motor driven drum (2) and assembled on a pair of vertical guides (3), comprising a fixed lower part (31) and a moveable upper part (32), being the lower parts (31) of the guides respectively arranged on each of the sides of a through opening (H) as shown in FIG. 2, reaching the total height of said opening, while the upper moveable part (32) is located above the opening, having two abutment elements (33), formed in this case by two parallel bars on which runs the flexible panel (1) of the quick opening door.

(16) The flexible panel (1) has in his lower end a bag (5) containing a heavy element (51) to facilitate the descent of the flexible panel in the operation of closing the quick opening door.

(17) As can be observed in FIG. 3, said bag (5) is thicker than the flexible panel (1) and thicker than the through opening defined between the abutments (33) linking the two upper portions (32) of the vertical guides (3) of the quick opening door. During normal operation (that is, without emergency) the quick opening door performs successive opening and closing movements and its lower end reaches in the opening position the maximum height (H) of the through opening.

(18) As can be observed in the attached drawings the system comprises, in combination with the quick opening door, a fire door (6) capable of moving lengthwise on a horizontal guide (7) between an opening position shown in FIGS. 1 and 2 and a closing position shown in FIGS. 7 and 8, said fire door (6) having in its top area a side extension (61) directed to the wall or surface in which the through opening (H) is defined. Said horizontal guide (7) is secured by different points (T) to the wall or surface in which the through opening (H) is defined.

(19) The fire door (6) performs its closing action against a closing surface comprising at least two vertical struts (8) on the external sides of the frame (3) of the quick opening door. In this closing position the side extension (61) defined in the upper part of the fire door has to establish a closing action above the lower part (31) of the vertical guides (3) for the quick opening door.

(20) To this end and in order that the side extension (61) of the fire door does not collide against the upper part of the vertical guides (32) of the quick opening door on occasion of an emergency actuation in case of a fire warning, the quick opening door carries out an over-opening, raising its lower end above the through opening (H); in this way, the bag (5) secured to the lower end of the flexible panel acts on the abutment elements (33) moving the upper part (32) of the vertical guides (3) towards the upper area as shown in FIGS. 4, 6 and 7, and defining between the upper part (32) and the lower part (31) of the guides (3) a sufficiently ample passage in order that the fire door (5) can move to the closing position as shown in FIGS. 4, 5 and 6 establishing the closing with the side extension (61) above the through opening door as shown in FIGS. 7 and 8, without said side extension interfering with the upper part (32) of the vertical guides or with any other element of the quick opening door.

(21) As shown in FIG. 9, the fire door (6) has in its vertical frame a plurality of abutments elements (62) aimed at blocking the door in the closing position against the flameguard (8) in one of its sides and against a vertical strut (8) in another of its sides. Said abutment elements enhance the stability of the closing of the fire door (6) in case of fire or explosion.

(22) The system has actuating means (9) connected to a fire warning system (not shown) which means are scheduled to carry out a normal actuation of the quick opening door up to the maximum height of the through opening, keeping the fire door open; or carrying out alternately an emergency actuation to provoke the over-opening of the quick opening door and the closing of the fire door.

(23) In the variant which has been shown in FIGS. 10 to 13 it has been provided the fire door (6) of the system to be mounted in a swiveling way instead of a sliding way, so that the proposed solutions can be adapted to places where no sufficient space is available to locate the fire door, as may be a corridor, because no side spaces exist to permit the opening of the fire door.

(24) In case of needing such a version, the structure of the quick opening door (3) will be still subdivided in a lower portion (31) and an upper portion (32) which serve as guide for the flexible panel (1) of the quick opening door and, in case of a warning signal being received by the actuation means (9), provokes the flexible panel (1) of the quick opening door to carry out an ascent movement acting against the abutments (33), displacing the upper portion (32) of the vertical guides (3) toward the upper area.

(25) In said version, the fire door of the original embodiment (6) is formed by one or two leaves (63, 63), which function is to close the through opening (H) in case of fire, overlapping one of the leaves on the other leave in case of two leaves, or swiveling only in one of the swiveling points (T).

(26) In said version, the part (61) attached to the fire door (6) may be substituted by a swiveling part (64) with the suitable size that in case of a warning signal and at the same time the flexible panel (1) of the quick opening door is running upwards towards the over-opening position by the action of said warning signal, displacing the upper portion (32) of the vertical guides (3) towards the upper area, swivels on a shaft or hinge (65) under the action of the over-opening movement of the upper portion (32) of the vertical guides (3), so that, said swiveling part (64) switches from a vertical position to a horizontal position as can be seen in FIG. 13, covering in this way the upper part of the through opening (H) and acting in its turn as closing upper frame for the swiveling leaves (63, 63) of the fire door.

(27) After having sufficiently described the nature of the invention, as well as a preferred embodiment of the same, it is stated to all effects that the materials, shape, size and arrangement of the described elements can be modified, whenever the changes do not mean the alteration of the essential characteristics of the invention, which is claimed as follows.
