    DESCRIPTION
    Folding screen
    Object of the invention
    The present invention relates to a folding screen that incorporates a mechanism to extend the upper part of the hidden screen in the lower part, whose performance 5 for elevation improves the mechanisms existing in the market. The screen is applicable in any space that you want to divide into diaphanous areas or make temporary enclosures in open spaces.

    Technical problem to be solved and background of the invention 10
    In the hospitality industry, due to legal restrictions for smoking inside the premises, the use of terraces, which are traditionally used only in the summer stage, is increasingly used, but with facilities that allow its use throughout the year , so that the users of the terraces can smoke in them because they are open spaces. fifteen

    To be able to close a terrace, a device is used that allows the space to be opened outdoors when the weather conditions so recommend. There are many devices that manage to make a more or less good closure of open terrace spaces. The use of screens is very widespread, which have a fixed lower part 20 and an upper part which, by means of an up and down mechanism, can be hidden next to the lower part. The use of awning, or curtain, elements that are rolled up on the top of the screen or on the side of the screen is also very widespread, leaving the space open, and that unfold quickly and easily, closing The open space. 25

    The aforementioned folding screens can be used either for the closing of the terraces as already mentioned, or to create independent spaces by separating them in large spaces, for example as elements for separating areas within an office or reception windows. 30

    In offices it is often necessary for the type of work to develop the separation between co-workers, which, to date, is carried out by removable screens that, when a modification of the office configuration is required, must be disassemble and reassemble at another location or discard the screen, so the use of separation screens from those currently in
    In use, it has the disadvantage that the configuration of the office must be planned in the very long term and the changes are costly and complicated. With a folding screen of those currently in use, the problem is that the mechanisms of rise and fall, because they are exposed and used very infrequently, get stuck and damaged.
     5
    The current screens, to perform the rise and fall of the upper part, have a mechanism consisting of a counterweight that balances the upward / downward movements of the screen, which presents problems throughout the life of the mechanism.
     10
    The counterbalance of the mechanisms known in the state of the art generates problems in the assembly and transport of the screen, since it requires a space inside the lower part of the screen that therefore elevates the dimensions thereof.

    Likewise, the counterbalance system used in the folding screens known in the state of the art is accessible from the outside of the screen without any fairing or any element that prevents access to the system, which creates security problems, since that during the up and down movements of the system entrapments can occur, in addition, when exposed, dust particles, beach sand and any foreign element are introduced into the counterweight system, so this system entails some work of maintenance in order to avoid its degradation.

    The first frame (4) of the fixed screen (2) comprises sides where recesses (5) are located that guide the movement of the mobile screen (3) along said first frame (4) and also comprises a first base (20) located in the lowest position of the first frame (4) considering the operating position of the folding screen (1). Covering the recesses (5) by the highest area of the fixed screen (2) 20 is an upper cover (22) that protects access to a lifting mechanism (8) from the upper area of the folding screen (1) .

    The mobile screen (3) comprises a second frame (6) with sides that comprise projections (7) that fit into the recesses (5) of the first frame (4) of the fixed screen (2), so that the movement of the mobile screen (3) is guided by the position of the projections (7) inside the recesses (5), the second frame (6) also comprises a second base (21) located in the lowest position of the second frame (6) considering the operating position of the folding screen (1).
     30
    The folding screen (1) object of the invention comprises sliding joints (19) housed in the recesses (5) of the fixed screen (2) that facilitate sliding of the mobile screen (3) on the fixed screen (2) . In the preferred embodiment of the invention, the sliding joints (19) are formed by nylon bushings housed in the recesses (5) of the fixed screen (2). 35

    The folding screen (1) object of the invention comprises a lifting mechanism (8) that governs the movements of ascent and descent of the mobile screen (3). Said lifting mechanism (8) is located only on one side or on both sides of the first frame (4) of the fixed screen (2), the situation on both sides of the fixed screen (2) provides a greater safety since the effort to raise the mobile screen (3) is divided between the two sides of the fixed screen (2).

    The lifting mechanism (8) comprises:
    - a pulley (9),
    - a fork (10), 10
    - a guide bushing (11),
    - a piston (12) comprising a plunger (13) and a body (14), and
    - a drag cable (15).

    The piston (13) of the piston (12) is fixed by means of a support (24) to the first base (20) in the lower zone of the first frame (4) of the fixed screen (2). Fixed on one side of the fixed screen (2) is the guide bushing (11) through which the body (14) of the piston (12) runs. In the body (14) of the piston (12), at the opposite end of the piston (13), is the fork (10) on which the pulley (9) is located.
     twenty
    The piston (12) incorporated in the fixed screen (2) develops a power that is determined by the dimensions of the mobile screen (3) and the characteristics of the glass incorporated in the mobile screen (3).

    The position and size of the guide bushing (11) in the fixed screen (2) is such that it allows the displacement of the body (14) of the piston (12) inside, and the displacement of the body (14) of the piston (12) performs the lift to a final position of the mobile screen (3).

    The drag cable (15) is fixed at one end to the guide bushing (11) at a first 30 fixing point (16), and at the other end to the movable screen (3) a second fixing point (17) located in a second base (21) of said movable screen (3), with the drag cable (15) passing through the pulley (9).

    The displacement of the body (14) of the piston (12), in an upward motion, raises the movable screen (3). By means of the lifting mechanism (8) arranged in the screen
    folding (1) object of the invention the travel of the mobile screen (3) doubles the travel of the body (14) of the piston (12), which translates into an elevation of the mobile screen (3) greater than the elevation of the screens known in the state of the art.

    Also, to prevent the mobile screen (3) from accidentally exiting its movement from the fixed screen (2) preventing the projections (7) from leaving the recesses (5), the mobile screen (3) comprises at least one second stop element (18b) that contacts a first stop element (18a) of the fixed screen (2) such that when the folding screen (1) is in the deployed position, the second stop element (18b) of the mobile screen (3) contacts the first stop element (18a) of the fixed screen 10 (2).

    The folding screen (1) object of the invention comprises a safety closing element (25) that prevents the movement of the mobile screen (3) once said mobile screen (3) is in the folded position, so that it is prevented an unauthorized manipulation of the folding screen (1) object of the invention.

    This safety closing element (25), in one embodiment, is formed by a pin that is placed on the upper cover of the fixed screen (2) and when the mobile screen (3) is in a folded position it adjusts to the upper part of the mobile screen (3) preventing 20 any movement of said mobile screen (3).

    Protecting the lifting mechanism (8), inside the first frame (4) of the fixed screen (2) is an inner cover (23), which covers the gap in which the lifting mechanism (8) is located preventing the entry of dirt into the lifting mechanism (8) and also provides security preventing access to said lifting mechanism (8) and therefore unauthorized manipulation of the folding screen (1).

    The invention should not be limited to the particular embodiment described herein. Experts in the field can develop other embodiments in view of the description 30 made here. Accordingly, the scope of the invention is defined by the following claims.
