    Closing shutter. Object of the invention.
    The object of the present invention is a closing shutter, intended to be mounted on doors, windows or any other access opening to a room; and that it presents constructive peculiarities oriented to allow the closing of the access opening and an upper opening or a lower opening thereof. Field of application of the invention.
    This invention is applicable in the field dedicated to the manufacture of enclosures for building openings and in particular blinds. State of the art
    Currently, window blinds, doors or the like are widely known, comprising: a frame provided with two vertical uprights with lateral guides and an upper upright; a set of articulated slats having at its upper end fastening straps to a rotating drum that can be operated manually or in a motorized way, in order to achieve the winding of the slats in the drum defining the blind a lower opening, or the unwind of the slats with the consequent closing of the blind.
    In this closed position the slats are arranged vertically and with their lateral ends housed in the guides of the vertical uprights.
    These blinds allow only the lower opening by lifting and winding the slats in the upper drum; so that the free space for lighting / ventilation is always located at the bottom. This implies that when the blind is raised, there is a significant danger of falling objects, animals or people outside because there is no protection element to avoid such risk.
    This opening of the blind is also incompatible with privacy when the open hole is found in the lower area of the enclosure and does not allow optimal use of sunlight.
    Therefore, the technical problem that arises is the development of a blind that allows the problem described above to be satisfactorily resolved. Description of the invention
    The closing shutter object of this invention is of the type mentioned in the pre-characterizing part of the first claim, comprising: a frame provided with two vertical uprights with lateral guides and an upper upright; and a set of articulated slats having at its upper end fastening straps to a first pulley of a rotating drum in which the slats are wound in a lower opening position of the blind.
    This blind has constructive particularities that, in addition to allowing the closing and the lower opening of the recess, analogously to a conventional blind, also allows a superior opening of the blind, so that the recess for ventilation / lighting of the room It can be defined, for convenience, both at the top and bottom of the blind.
    This blind therefore allows to increase the security and privacy of the occupants of the room without losing lighting / ventilation and keeping intact all the virtues and advantages of the blinds mentioned in the previous section and currently existing.
    To achieve the proposed objectives, the closing shutter object of this invention has the particularity of comprising clamping straps of the set of slats of a suitable length to allow the unwinding of the drum slat assembly and its descent, passing through a closed position to an upper opening position of the blind, in which at least a part of the lower slats are arranged horizontally and folded in a zigzag in a lower area of the frame, with a gap being opened above the slats, in the upper part of the framework.
    For this folding of the slats in the lower position to be viable; the vertical guides have: -a top portion of a fixed width for guiding the slats in a vertical position and -a lower portion of variable width for guiding the slats in a vertical position to a closed position, and their horizontal arrangement, folded in zigzag, in the upper opening position of the blind.
    These characteristics therefore allow the slats to exceed the closing position in the downward direction and overlap horizontally, folded in zigzag, in an upper opening position, in which they define a lighting / ventilation gap in the upper area of the frame.
    In accordance with the invention, the lower portion of variable width of the vertical guides comprises an open side, and a vertically movable profile, synchronized with the movement of the louvers of the blind, between a lower position in which said lower portion of the guides has a width equal to that of the upper portion; and an upper position in which said open side is exposed and said lower portion has a greater width, suitable for stacking the slats folded in zigzag.
    The movable profile of the vertical guides is connected by means of a clamping cable to a second winding pulley integral with the rotating drum; presenting the first winding pulley of the clamping straps of the slats and the second winding pulley of the clamping cable of the movable profile a predetermined diameter ratio, so that in the closed position of the blind the movable profile is arranged in the lower position; and in the upper opening position of the blind, said movable profile is arranged in the upper position, freeing the adequate space to allow the slats to be zigzag.
    This relationship of diameters is predetermined so that: when the slats are lowered to a closed position of the blind, the movable profile also descends to the lower position, guiding the slats in the vertical closing position of the blinds; and during the continuation of the lowering of the slats towards the zigzag stacking position and upper opening of the shutter said movable profile moves towards the upper area, discovering the open side in the lower portion of the guide and providing said lower portion of the guide of the necessary width so that the slats can be stacked horizontally in zigzag.
    The change of downward-ascending movement of the movable profile during the descending movement of the slats and the rotation of the drum in the same direction is determined because initially the support cable of the movable profile is unwound from the second pulley, said movable profile descending , and by continuing to rotate the drum in the same direction said support cable begins to wind in the opposite direction on said second pulley, causing the rise of said movable profile.
    Since in the upper opening position of the blind the movable profile is arranged superiorly leaving the open side of the lower portion of the guides uncovered, the vertical uprights of the frame comprise a fixed stop, facing said open side of the lower portion of the vertical guides and that together with said lower portion of the guides delimit an area for the horizontal arrangement of the slats, folded in zigzag.
    This fixed stop prevents the folded slats can move frontally and be removed from the inner hollow of the frame. Description of the figures.
    To complement the description that is being made and in order to facilitate the understanding of the characteristics of the invention, a set of drawings is attached to the present specification in which, for illustrative and non-limiting purposes, the following has been represented:
    - Figure 1 shows an elevational view of an embodiment example of the closing shutter according to the invention, seen from its inner face and in a lower opening position.
    - Figure 2 shows a view analogous to the previous one with the blind in a closed position.
    - Figure 3 shows a view analogous to the previous ones with the blind in an upper opening position.
    - Figure 4 shows a partial perspective view of the closing shutter in the closed position, sectioned by a vertical plane, and seen from its outer face.
    - Figure 5 shows a view analogous to Figure 4, passing the slats from a closed position to an upper opening position of the blind, during the ascent of the movable profile of the vertical guide.
    - Figure 6 shows a view analogous to Figures 4 and 5, with the slats stacked in zigzag, in the upper opening position of the blind and with the profile movable in the upper position. Preferred embodiment of the invention.
    The closing shutter shown in figures 1 to 3 comprises: a frame (1) provided with two vertical uprights (11) with lateral guides (12) and an upper upright (13); and a set of articulated slats (2) whose upper end is fixed by means of fastening straps (21) to a first pulley (31) of a rotating drum (3), said first pulley (31) having a predetermined diameter.
    This rotating drum (3) is operable in one or another direction of rotation by means of a manually operated belt (32), allowing the winding and unwinding of the slats (2) on it.
    Depending on the rolled or unwound position of the slats (2) on the drum (3), the blind can be arranged in: a lower opening position represented in Figure 1; a closing position represented in figure 2 or in an upper opening position represented in figure 3 and in which the slats are arranged horizontally superimposed, and folded in zigzag in the lower part of the frame, as it is observed more clearly in figure 6.
    To allow such positions the vertical guides (2) have an upper portion (12a) of a fixed width for guiding the slats in a vertical position and - a lower portion (12b) of variable width depending on the position of a profile movable (4) vertically, said lower portion (12b) allowing the vertical clamping of the slats (2) in the closed position of the blind as shown in Figure 4, and the horizontal arrangement of the slats (2), folded in zigzag, in an upper opening position of the blind as shown in figure 6
    The lower portion (12b) of the vertical guides comprises an open side, which is covered by movable profile (4) when it is in a lower position shown in Figure 4, and which is discovered when said movable profile (4) is disposed in an upper position represented in figure 6.
    Said movable profile (4) is connected by means of a clamping cable
    (41) to a second winding pulley (33) integral with the rotating drum (3).
    The first winding pulley (31) of the clamping belts (21) of the slats and the second winding pulley (33) of the clamping cable (41) of the movable profile (4) have a predetermined diameter ratio, so that during the movement of the slats (2) towards the closed position, the movable profile moves towards the lower position as shown in figure 2 and when the slats (2) continue to descend towards the upper opening position, such as shown in figure 5, said movable profile (4) moves towards the upper position, exposing the open side of the lower portion (12b) of the vertical guides (12) so that the slats (2) can be Stacking in zigzag, until reaching the upper opening position of the blind represented in figure 6.
    As can be seen in Figures 4 to 6, the vertical uprights (11) have a fixed stop (14) facing the open side of the lower portion (12b) of the vertical guides and which delimits together with said lower portion (12b) of the guides (12) an area for the horizontal arrangement of the slats (2), folded in zigzag, without the possibility of being extracted frontally from the frame (1).
    Once the nature of the invention has been sufficiently described, as well as a preferred embodiment, it is stated for the appropriate purposes that the materials, shape, size and arrangement of the described elements may be modified, provided that this does not imply an alteration. of the essential features of the invention that are claimed below.
