Definitions

  • This invention relates to a support framework for any type of rolling curtains and associated device for a quick and final stretching unrolling adjustment of said rolling curtains.
  • rolling curtains which are generally used, for example, to protect a room from excessive light - as a screen - or from insects getting in - as a mosquito-net -, are generally wound up around an upper roller which rotates on its axis and is supplied with an internal spring which, when loaded by the curtain unrolling, rolls the support roller whenever the bottom bar fixed to the curtain bottom- either along its full length or along most of it - is released upwards.
  • This invention aims to avoid the above inconvenient.
  • Another aim is to supply a framework with associated device for the curtain height unrolling adjustment overcoming the above mentioned disadvantage.
  • This invention also aims at providing adequate means to keep the curtain edges within the sliding guides, made to ensure proper protection, and, at the same time, to avoid unnecessary thickening of the edges in the guides due to thickening or similar other means generally adopted in this sector.
  • This invention also aims, once the apparatus is fitted on site, at ensuring that the curtain unrolling and uprolling parts can work freely.
  • the support framework for any type of rolling curtains and in particular for window opening protecting mosquito nets is of the type including a box containing a longitudinally grooved hollow roller with a screen, which is the actual curtain, wound around it, at the two box ends a first and a second head being fitted for the free support of said roller and of said screen elastic uprolling devices and vertical guides for said screen edges and hooking elements for keeping the curtain tight when in straight position, and it is mainly characterized by the fact that the second head is supplied with a device for a quick and final stretching unrolling adjustment of said screen, that a distance piece is provided to ensure clearances required between the parts, that the head is fitted on the said framework after cutting the box and associated parts according to the desired length, thus allowing direct framework mounting without previous inspection for the necessary measurements.
  • Drawing No. 7 shows a detail of the stop element acting as a pin for the curtain uprolling roller and as an anchor for the helical spring.
  • the framework - which is generally referred to with 1 - mainly includes a parallelepiped box 2 containing a hollow roller 3 with a longitudinal groove 4 and having wound around it a screen 5 which is the actual curtain, advantageously a mosquito-net, and which comes out of box 2 through a longitudinal slit 6, on the box 2 ends being fitted, vertical guides 7 with a height corresponding to the one of the window opening where the framework is to be mounted.
  • the box 2, the roller 3 and the curtain 5 are directly assembled at the factory according to standard measures not necessarily corresponding to the ones of the window opening where the framework and relevant curtain are to be mounted in.
  • a support cylinder 8 will be placed which is fixed on the first head 9 of the box 2, the roller 3 being free to rotate on this cylinder.
  • the said element 8 has a threaded and frustum tapered end to house, according to a well known technique, one end of a spring 10 able to give the roller 3 the energy needed to roll up the screen 5 again , the second end of the said spring engaging another element 44 which is contained inside the hollow roller 3 and is supplied with an appendix cooperating with the groove 4, thus enabling this element to run freely along the said roller, without however rotating with reference to the latter, thanks to the appendix interference with the said groove during spring 10 loading and, of course, unloading.
  • the device for a quick and final stretching unrolling adjustment of the screen 5 includes a second head 11 which is to cooperate with the box 2 end opposite to head 9, at its centre being provided with a round hollow 12 and a vertical hollow 13 off-centre with respect to the said hollow 12.
  • the wheel 17 has a hub 19, which is also a support of roller 3 end, from the front of which 20 a peg 21 protrudes which in its turn, as described below, engages a similar peg 22 on the side of an internally threaded sleeve which is to engage pin 16 thread.
  • the vertical hollow 13 is off-centre with respect to round hollow 12 and will house a bolt 25 which can have a slotted hole 26 for an adjusting and locking screw 27.
  • the said latch 25 goes in between the notches of the wheel 17 to stop roller rotation at a pre-determined position, chosen by the person installing the unit, of roller 3, thus achieving a proper stretching of the curtain once it is hooked via bar 29 to the height-adjustable lower stop 31 for example of the screw type.
  • the said element 25 has an asim- metric upside-down "V" shape.
  • each vertical guide has a substantially C-shaped cross section engaging inside of it and along the whole guide length a brush lip seal 28.
  • the lower edge of the screen 5 is tied to a bottom bar 29 with constant section along its full length.
  • Number 34 indicates a head element to be inserted in the botton bar 29, which functions both as sliding element inside the guides 7 and as stop-peg in the lower blocking-de- , vice element of the bar by engaging itself with the edge 35 underneath screw 31, as schematically shown in Drawing No.5.
  • the said element 34 is inserted in the hollows existing in the bar head profile, in particular the base 43 will engage itself in the bar upper groove 36 and the ⁇ peg 37 will engage itself in the central opening 38.
  • element 34 at the two bar ends allows the said bar to be cut according to the required length without having to prolong the lock wing 35 beyond necessary.
  • this stop element 34 is a separate piece, it may be built of a material different from the bar 29 one, such as of synthetic material like plastic, being thus more suitable to stand wearing conditions caused by interference with the head 31, thereby making the whole unit much more effective and reliable.
  • Number 39 shows a short handle, built of any material suitable for the purpose, with a dovetail-shaped rear for fitting into the bar 29 groove 40 and for making it reach, whatever bar 29 length, the central part, this bar/handle engagement solution also reducing the overall weight of the whole unit, without affecting practical use.
  • Number 41 indicates curtain 5 operating string, which engages on bar 29 by inserting it and having it slide inside the upper hollow 36 until it reaches the curtain centre line.
  • the string 41 may also be inserted in the groove 40 and, instead of a single centrally placed handle 39, there may be two or more of them- i.e. for much larger window openings, the string 41, however, being able to reach, always by sliding, the central part of bar 29, that is to say of the curtain 5, in the space between one handle and the next.
  • Number 33 indicates a shimming, used as a distance piece, supplied with a grip 30, such as an external ring, for example, to facilitate hooking and pulling.
  • a framework 1 having about the same length and width as the maximum ones of the window opening on which the rolling curtain has to be installed: no previous inspection is necessary before proper installation.
  • the window opening width is carefully measured and the box 2, the roller 3 and the screen 5 are simultaneously cut according to the window opening width, as well as the bottom bar 29.
  • roller 3 ends is placed on the support cylinder 8 the head of which 9 has been previously mounted inside the window opening and on the opposite end of the roller itself the threaded pin 16 is inserted engaging the grooved 4 sleeve 23 appendix 24; pin 16 end 15 is inserted in hole 14 of the head 11 in order to place the wheel 17 inside the round hollow 12.
  • Head 11 is then placed inside window opening opposite to head 9; sleeve 23 works as support element opposite to support element 8.
  • the screen 5 final height unrolling adjustment is performed against spring 10 contrasting action and peg 22, which follows a helicoidal trajectory according to pin 16 pitch, at a certain stage of unrolling, interferes with peg 21 making the wheel 17 turn.
  • the screen 5 With a pressure on the bottom bar 29, the screen 5 will be stretched according to its vertical fibres and it will be maintained stretched by hooking the protruding element 35 underneath the hooking element 31.
  • the screen 5 longitudinal edges are kept inside the guides 7 by the elastic pressure exerted by the brush lip seal 28, whereas the proper tightness between the bottom bar 29 and the window opening lower edge is obtained by means of an extension 32 of the screen 5 inserted into the lower hollow of bar 29 and protruding from below.
  • hollow 13 can even be on axis with round hollow 12 and stop element 25, on the point, even though in a less reliable manner, can even have a simmetric upside-down "V" shape.
