Definitions

  • the present invention relates to a drop-down screen incorporating a mechanism for extending the top of the screen concealed in the lower part, which offers better lifting performance than the mechanisms currently on the market.
  • the screen may be used in areas that are to be divided into open areas or to create temporary enclosures in open spaces.
  • a device In order to enclose a patio, a device is used that enables the space to be opened up to the open air when weather conditions permit. Many different devices are currently in use to enclose open patio-type spaces with greater or lesser success. Very frequently, screens are used with a fixed lower part and an upper part which, by means of a raising and lowering mechanism, can be concealed together with the lower part. It is also very common to use awning or curtain-type elements, which roll up into the top or side of the screen, leaving the space open, and which can be rolled out quickly and simply to enclose the open space.
  • Said screens can be used either -as mentioned- for enclosing terraces or to create independent spaces by means of separations in large spaces, for example to separate different areas within an office or different reception windows.
  • the counterweight system used in the drop-down screens known in the current state of the art is accessible from the exterior of the screen and has no fairing or other element to prevent access to the system. This causes safety issues, since entanglement may occur during raising and lowering of the system. Moreover, because it is exposed, particles of dust, beach sand and other foreign bodies can enter the counterweight system and this system therefore requires maintenance to prevent deterioration.
  • the present invention relates to a drop-down screen, comprising a fixed screen having a first frame containing two side pieces with at least one recess on each side and a first base, and a sliding screen having a second frame containing two side pieces with at least one flange on each side piece and a second base
  • movement of the sliding screen is guided by the position of the flanges inside the recesses and it contains at least one mechanism for raising the sliding screen.
  • Each mechanism for raising the drop-down screen according to the present invention contains a guide bushing attached to one side piece of the first frame, a piston containing a plunger and a body, a bracket attached to one end of the body of the piston, a pulley located in the bracket, and a pulley cable.
  • the plunger of the piston is attached to the first base, movement of the body of the piston is guided by the guide bushing, and the pulley cable is attached at one end to the guide bushing and at the other end to the second base and passes through the pulley.
  • the plunger of the piston is attached by means of a support to the first base of the first frame of the fixed screen.
  • the drop-down screen contains at least one inner cover attached to the interior of the first frame of the fixed screen, which covers the lifting mechanism.
  • the drop-down screen has slide seals housed in the recesses of the fixed screen which aid the movement of the sliding screen along the fixed screen.
  • the drop-down screen contains a safety locking element that prevents unauthorised manipulation of the drop-down screen.
  • the fixed screen contains a first buffer and the sliding screen contains a second buffer, such that the sliding screen moves along the fixed screen to a final position where the second buffer of the sliding screen comes into contact with the first buffer of the fixed screen, limiting the movement of the sliding screen along the fixed screen.
  • the drop-down screen (1) according to the present invention contains a fixed screen (2) and a sliding screen (3), with the fixed screen (2) containing a first frame, (4) along which the sliding screen (3) moves.
  • the drop-down screen (1) according to the present invention is positioned on the ground in such a way that, when the drop-down screen (1) according to the present invention is open, the fixed screen (2) is at the bottom and the sliding screen (3) has an upward and downward movement relative to the fixed screen (2).
  • the drop-down screen (1) according to the present invention is in the closed position, the fixed screen (2) and the sliding screen (3) are located one in front of the other.
  • the first frame, (4) of the fixed screen (2) contains side pieces having recesses (5) that guide the movement of the sliding screen (3) along the aforesaid first frame (4) and also a first base (20) located in the lowest position of the first frame, (4) in the operating position of the drop-down screen (1). Covering the recesses (5) in the top area of the fixed screen (2) there is an upper cover, (22) restricting access to a lifting mechanism (8) from the top area of the drop-down screen (1).
  • the sliding screen (3) has a second frame, (6) with side pieces containing flanges (7) that fit into the recesses (5) in the first frame, (4) of the fixed screen (2), in such a way that the movement of the sliding screen (3) is guided by the position of the flanges (7) inside the recesses (5).
  • the second frame (6) also contains a second base, (21) located in the lowest position of the second frame, (6) in the operating position of the drop-down screen (1).
  • the drop-down screen (1) contains slide seals (19) housed in the recesses (5) of the fixed screen (2) which aid movement of the sliding screen (3) along the fixed screen (2).
  • the slide seals (19) are formed by nylon bushings housed in the recesses (5) of the fixed screen (2).
  • the drop-down screen (1) contains a lifting mechanism (8) that governs the movements of raising and lowering the sliding screen (3).
  • This lifting mechanism (8) is situated either in one side piece or in both side pieces of the first frame, (4) of the fixed screen (2); locating it in the two side pieces of the fixed screen (2) offers greater safety since the effort of raising the sliding screen (3) is distributed between the two side pieces of the fixed screen (2).
  • the lifting mechanism (8) contains:
  • the plunger (13) of the piston (12) is attached by means of a support (24) to the first base (20) in the lowest area of the first frame (4) of the fixed screen (2).
  • the guide bushing (11) inside which the body (14) of the piston (12) runs is attached to a side piece of the fixed screen (2).
  • the power of the piston (12) incorporated in the fixed screen (2) is dependent on the dimensions of the sliding screen (3) and the characteristics of the glass in the sliding screen (3).
  • the position and size of the guide bushing (11) in the fixed screen (2) are such as to allow the body (14) of the piston (12) to move inside, and the movement of the body (14) of the piston (12) lifts the sliding screen (3) to its final position.
  • the pulley cable (15) is attached at one end to the guide bushing (11) at a first attachment point, (16), and at the other end to the sliding screen (3) at a second attachment point, (17) located in the second base (21) of the aforesaid sliding screen (3), with the pulley cable (15) passing through the pulley (9).
  • the sliding screen (3) is raised by the upward movement of the body (14) of the piston (12).
  • the lifting mechanism (8) provided in the drop-down screen (1) according to the present invention the movement of the sliding screen (3) duplicates the movement of the body (14) of the piston (12), which results in a greater elevation of the sliding screen (3) than that known in the current state of the art.
  • the sliding screen (3) contains at least one second buffer, (18b) which comes into contact with a first buffer, (18a) in the fixed screen (2) such that when the drop-down screen (1) is in the open position, the second buffer, (18b) of the sliding screen (3) comes into contact with the first buffer, (18a) of the fixed screen (2).
  • the drop-down screen (1) according to the present invention contains a safety locking element (25) that prevent movement of the sliding screen (3) once it is in the closed position, thus preventing unauthorised manipulation of the drop-down screen (1) according to the present invention.
  • this safety locking element (25) is formed by a pin situated in the upper cover of the fixed screen (2) and when the sliding screen (3) is in the closed position it fits into the top of the sliding screen (3) preventing any movement of this sliding screen (3).
