    DETAILED DESCRIPTION

    [0036] The closure system object of the invention is installed on a wall (P) separating two adjoining rooms and featuring a door opening (H) between said rooms.

    [0037] This system comprises a quick-opening door (1) and a fire door (2), which can be operated independently and are suitable for the opening and closing of the door opening (H).

    [0038] The quick-opening door (1) comprises a flexible roll-up sheet (11) that can be rolled up on a motorised drum (not represented) housed in an upper casing (12) and able to be vertically displaced along guides (31) defined in vertical uprights (3), and between an opening position and a closing position of the door opening (H).

    [0039] The quick-opening door (1) is adjustedly installed within the door opening (H), and can be entirely or mostly housed in said opening (H) depending on the thickness of the wall (P).

    [0040] In FIGS. 1 to 7, the fire door (2) comprises a sliding fireproof layer (21) arranged on one of the sides of the wall (P) and installed being able to be horizontally displaced with respect to a support guide (22), between an opening position and a closing position of the door opening (H).

    [0041] Said support guide (22) is fixed to the aforementioned side of the wall (P) forming the door opening (H), and located above, i.e., at a height greater than said door opening.

    [0042] The fire door (2) comprises a perimeter frame that forms a support area in the closing position and is made up of the vertical uprights (3), carriers of the guides (31) along which the flexible sheet (11) of the quick-opening door (1) circulates, and of a rearward fireproof cover (4) of the upper casing (12) of the quick-opening door (1); so that both doors have a common clearance opening.

    [0043] In the embodiment of FIG. 4, the vertical uprights (3) are formed by single-piece profiles (32) with a uniform cross section, filled with fireproof material.

    [0044] In the embodiment of FIGS. 5 and 6, the vertical uprights (3) comprise: a front profile (33), wherein the vertical guides (31) of the quick-opening door (1) are defined; a rear profile (34) fixed to the front profile (33); and a layer of insulating material (35) located between the front and rear profiles (33, 34).

    [0045] The detail view of FIG. 6 shows the rearward fireproof cover (4) of the upper casing (12) of the quick-opening door (1), which together with the vertical uprights (3) forms the closure area of the fire door (2).

    [0046] The contact of the fireproof layer (21) against the closure area can be determined by a counterweight, by a change in direction of the support guide (22), or by any other means, since this does not affect the essence of the invention.

    [0047] With the aforementioned features, the quick-opening door (1) and the fire door (2) can be operated independently, which enables them to be simultaneously or individually displaced to either the opening or closing position, without interfering with each other.

    [0048] FIGS. 7, 8 and 9 show a fire door (2) that can be opened, with two fireproof layers (23) that, if required, make frontal contact against the perimeter frame made up of the vertical uprights (3) and of the rearward fireproof cover (4) of the upper casing to perform the fire closure.

    [0049] This alternative to the invention is provided to be able to locate the concept of this combined door in spaces wherein the placement of a sliding fire door is not possible due to lack of space on the sides. In this variant of the invention, the fire door has two layers although it can also have a single layer, depending on the dimensions.

    [0050] The operation of this variant of the invention is the same as in the case of the sliding fire door (2). That is, the fire door that can be opened has the fireproof layers (23) in the normally open position, the quick-opening door (1) being the one that opens and closes the door opening (H) located in the wall (P) and, in the event that a fire is detected, the fireproof layers (23) of the fire door close automatically, either by means of an electromagnet that stops holding them in the open position or in another way, so that the door opening (H) is closed and protected against fire.

    [0051] Having sufficiently described the nature of the invention, in addition to a preferred exemplary embodiment, it is hereby stated for the relevant purposes that the materials, shape, size and layout of the described elements may be modified, provided that it does not imply altering the essential features of the invention claimed below.
