Definitions

  • the present invention relates to a device for raising and lowering packet blinds and pleated blinds, provided with means for orderly winding up the blind driving cords.
  • cords are usually used, which cords are coupled to a bottom or lower bar, associated with the bottom end portion of the blind, said driving cords being wound on spools, bobbins or the like, which are rotated either manually or by means of electric motors and electronically controlled electric motors.
  • each cords, as it is wound on its spool assumes, very frequently, a not ordered arrangement; in other words, the cord turns are frequently arranged on the winding spool in a random way, with continuous bridgings.
  • the task of the present in­vention is to overcome the above mentioned drawbacks, by providing a device for raising and lowering packet blinds and pleated blinds, provided with means for orderly winding the blind driving cords, adapted to evenly and orderly wind up the driving cords on the spool or winding body, so as to provide a constant or even diameter for each cord turn, thereby preventing the blind raising and lowering device for Jamming.
  • a device for raising and lowering packet blinds and pleated blinds in general provided with means for orderly winding up the blind driving cords, characterized in that said device further comprises a driving bar, driven into rotation by driving means, therewith there is associated, in a rotatively rigid and axial­ly sliding way, at least an outside threaded sleeve, engaging with a nut screw, formed on a supporting fixed bracket to axially displace said sleeve as said bar is rotated.
  • a blind raising and lowering cord which is wound about said sleeve and is re­spectively wound thereon and un-wound therefrom for raising and lowering a packet blind.
  • the device for raising and lower­ing packet blinds and pleated blinds in general, having means for orderly winding the blind driving cords comprises a driving bar 1, preferably of the slotted type, which comprises slots longitudinally extending through the overal length of said bar.
  • Said bar 1 at one end thereof, is asso­ciated with driving means which, in the embodiment being disclosed, consists of a driving assembly 2, which can be actuated by a ball chain 3 in order to cause said bar to rotate.
  • driving means which, in the embodiment being disclosed, consists of a driving assembly 2, which can be actuated by a ball chain 3 in order to cause said bar to rotate.
  • driving assembly 2 can also be replaced by other equivalent driving means, such as an elec­tric motor, an electronically controlled electric motor and the like.
  • said driving bar 1 there are coupled, with a spaced apart relationship, two sleeves 5, which, in their inside cavities, are pro­ vided with slots corresponding to said bar slots or, possibly, with a coupling pin for rendering said sleeves 5 rotatively rigid with said bar 1 but able of axially sliding with respect to said bar.
  • the sleeves 5 are provided with a thread 6 engaging with a corresponding nut screw 7 formed by suppor­ting fixed bracket 8 coupled to the section member 10 to be applied to a wall or a ceiling.
  • brackets 8 are pro­vided with a guide eyelet 11 therethrough said driving cords 12 are caused to slidingly pass, said brackets supporting the bottom bar 13 which, as it is conventional, is coupled to the bottom end por­tion of the packet blind.
  • the disclosed coupling causes said sleeves, rotatively rigid with said bar 1, because of their engaging with said nut screw 7, to be axially displaced, for a step, which de­pends on the pitch of the thread which has been set.
  • the driving cords 12, which are guided through the eyelets 11, will be wound on sub­sequent zones of the sleeve 5, so as to always pro­vide a proper winding arrangement.
  • the cords 12 which, as aforesaid, are af­fixed at their top ends to said sleeves 5, will be wound on said sleeves 5 with an even winding pitch, since the sleeve 5 will be displaced corresponding­ly to the rotation of said bar 1 for raising or lowering the blind, and, in this manner, the turns of the cords 12 will be not superimposed.
  • the disclosed coupling affords the possibility of safely preventing cord jammings from occurring and, accordingly, the raising and lowering speed of the blind will be held always at a constant value.
