Definitions

  • the present invention relates to a gate assembly comprising a plurality of parallel bars in a guide and actuator.
  • Gates are known which are constituted by vertical bars connected to one another by diagonal elements articulated in the shape of a parallelogram: the gate is arranged between an upper sliding guide and a lower sliding guide, and, when opened, they are packed at one side of the opening in which they are mounted.
  • Horizontally sliding gates of this type have the disadvantage of reducing the width of the gap, window or door in which they are mounted and they are furthermore easily attacked at the sliding couplings with the guides; said guides are in fact usually constituted by profiled elements with a U-shaped cross section, inside which the upper and lower ends of the bars simply slide, and it is easy to force said guides and twist off the ends of said bars.
  • the technical aim of the present invention is to obviate the above described disadvantages by providing a gate assembly comprising a plurality of parallel bars in a guide and actuator by means of which doors and windows are closed in an extremely solid and secure manner and which can be actuated in an extremely rapid manner and without physical strain.
  • an object of the present invention is to achieve the above described aim with a simple structure which is relatively easy to execute in practice, safe in use and effective in operation as well as relatively modest in cost.
  • a gate assembly comprising a plurality of parallel bars in a guide and actuator assembly which includes vertical slide guides, threaded stems rotatably mounted inside each of said guides and connected by kinematic coupling means rotatably actuated by a motor unit, a respective female thread being engaged along each of said stems, said bars being connected to one another by diagonal elements articulated in the shape of a parallelogram, characterized in that said bars (3) are guided with their ends into openings provided at said vertical slide guides and only the last lowest bar is rigidly associated with said female thread.
  • the numeral 1 generally indicates the guide and actuator assembly for a gate 2 according to the invention.
  • the gate 2 is of the type constituted by a plurality of parallel bars 3 which are connected to one another by diagonal elements (not illustrated) articulated in the shape of a parallelogram.
  • each of the bars 3 has respective guide skids 4 which have a T-shaped plan cross section.
  • Each vertical guide 5 comprises profiled elements 6a, 6b, joined by L-shaped elements 6c to define a substantially C-shaped cross section having an opening facing the opening of the opposite vertical guide; the skids 4 are loosely fitted to slide in the openings of the guides 5.
  • Profiled elements 6 are fixed by means of screws 7 to the wall all around the gap, window or door to be closed, and, optionally, a shaped profiled element 8, defining a vertical channel 9 for a blind (not illustrated), may be rigidly associated with said profiled elements 6; an outer wooden frame 10 can be fixed to said shaped profiled element 8, and the window or door is provided with the conventional frame for the glass pane toward the inside of the room.
  • a threaded stem 14 is rotatably mounted inside each of said guides 5 by means of upper bearings 11 and lower bearings 12 which are supported by respective ledges 13 fastened with screws inside the profiled elements.
  • a female thread 15 is threaded onto the stem 14 and is welded to an extension 4a of the skid of the last bar 3a (for example the lower one) of the gate, whereas the first bar 3b of the gate is fixed to the upper beam 17 by means of a bolt which blocks a lateral extension 19 of the bar.
  • the bearing 11 is supported by a ledge 13 which is arranged at a distance from upper beam 17 approximately corresponding to the thickness of the packed bars 3, when the gate is open.
  • the threaded stem 14 is connected to a similar threaded stem 14 of the other side of the window (not illustrated) by kinematic coupling means 20 which, in the case illustrated in the figure, are constituted by toothed sprockets 21 keyed to the lower ends of the stems 14 and connected in pairs by chains 22.
  • Said means 20 are contained inside the lower beam 25 of the window frame and are preferably actuated by means of an electric motor-reducer unit or manually with a crank.
  • the kinematic coupling means 20 are constituted by bevel gears which connect the threaded stems to a horizontal shaft contained in the lower beam 23.
  • the bars 3 of the gate 2 are usually constituted by two profiled elements 3c, 3d which are spaced with U-shaped cross sections, the openings whereof are opposite; parallelogram-shaped diagonal elements are mounted therebetween.
  • the female thread 15 is defined in a small block 29 which is rigidly associated with two parallel arms 30 which are fixed by welding, riveting or the like to the profiled elements 3a and 3b.
  • This embodiment allows to avoid the machinings required to fix the skids to the bars and reduces the weight of the movable parts (there is no longer the skids weight).
  • the upright is eliminated and the threaded stem is mounted between the profiled elements 3a and 3b which, if required, are perforated along vertical axes to allow the loose passage of the threaded stem.
  • opening and closure end stop switches or even mechanical stops constituted by unthreaded terminal regions of the stems (with lower stroke limit springs for the re-engagement of the female threads), or clutches or motor-overload releases are provided.
  • the lower bar can be equipped with a key-lock, for locking it to the lower beam, and the motor switch may be activated by a security key.
