Definitions

  • the present invention relates to a track mechanism, for the orientation and displacement of the strips of a vertical strip blind.
  • vertical strip blinds are largely utilised for the covering and decoration of windows in general, such blinds being constituted by adjacent strips of suitably reinforced fabric.
  • Such strips are suspended from conveniently formed members slidable along a hollow track support and able to cause coordinated orientation of the strips themselves by making them turn through a given angle about their vertical axes which are all parallel to one another.
  • assemblies which are commercially available at present for obtaining, with a single control, the displacement and orientation of the strips have a significant structural complexity and are therefore of rather high cost.
  • This structural complexity moreover, can detrimentally affect, at least in general, the correct operation of the product, or at least require frequent adjustments and/or replacement of parts.
  • the conventional type of displacement and orientation members for the strips usually have a not insignificant linear bulk, which only allows them to be used on rectilinear sections.
  • the document EP-A-0 081 465 which is a state of the art according to Article 54(3), discloses a mechanism for operating a vertical strip blind, including a first spindle supported by a prismatic box-like body at one end of which spindle there is formed a worm wheel and on which is fitted with the interposition of resilient biasing means an element provided with a circumferential projection having external teeth, the worm wheel of said first spindle engaging the partially toothed shaped end of a second spindle the axis of which is vertical, carrying a suitable shaped hook for support of the strip which constitutes a part of the blind; the prismatic box-like body being housed, with the first spindle disposed on one side in a sliding track provided with opposed guides for the passage of a flexible control member which is engageable with the toothed projection formed on the element which acts on the first spindle.
  • the object of the present invention is to eliminate the previously described disadvantages by providing a mechanical device for the manipulation of vertical strip blinds which will be structurally simple and therefore of low cost.
  • a particular object of the present invention is to provide a mechanical device for operating vertical strip blinds; which has a substantially limited bulk in such a way as to be used even on curved profiles.
  • Another object of the present invention is to provide a mechanical device for operating vertical strip blinds which will allow blinds having a central opening to be formed using only a single sliding track of suitable shape.
  • Another object of the present invention is to provide a mechanical device for operating vertical strip blinds which is made from a limited number of component parts cooperating together in such a way as to provide an extremely secure and reliable product for the user.
  • the said first spindle is disposed obliquely with respect to the second spindle; in this case, obviously, the corresponding toothed and partially toothed wheels formed at their facing ends and mutually engaging one another are of conical type, namely bevel wheels.
  • the operating mechanism for a vertical strip blind in question comprises a suitably shaped prismatic box-like body 1 having an almost trapezoidal shape, with a projecting portion 1' in which are formed mountings for housing and supporting a spindle 2 disposed with its axis preferably inclined or else vertical.
  • the spindle At its base portion the spindle is formed with a perimetral toothed wheel 3 similar to a toothed ring, above which is located a fixed collar 4. Upwardly from the toothed wheel 2 the spindle has a first cylindrical portion 2' and above this a second cylindrical portion 2" of smaller diameter.
  • the said resilient biasing means can be constituted by a coil spring or by a length of rubber tube, or by other functionally equivalent members suitably dimensioned and placed in compression by the pressing action of a resilient washer 19 for the purpose of acting as a friction clutch between the hollow cylindrical element 6 and the collar 4.
  • the lower toothed ring 3 of the spindle 2 is engaged by the upper end 20 of a second spindle 8 which has a mushroom head and teeth around part of its periphery. This latter is housed in such a manner that it can turn in a suitable seat 9 formed in the base of the box-like body 1 adjacent its projecting portion 1'.
  • the portion of the box-like body 1 constituting the said seat 9 further defines outer guides 10 for retaining and sliding along the flanges 11 of a C-shape section 12.
  • This section having a vertical plane of symmetry, has, in particular, at the inner faces of the two lateral walls respective open channels 13 of suitable section which can house a slidable member 14 which acts to cause rotation of or to draw along (in one of two directions) the toothed ring 7.
  • the said slidable member can be constituted, as required or preferred, by a cord or by a chain carrying balls or other suitable projecting elements, or by a perforated band or the like able to engage the teeth of the toothed ring.
  • the projecting members of the said slidable operating member should extend from the channels 13.
  • the toothed ring 7 the rotation of which is essentially resisted by the action of the resilient means 5, starts, at first, to turn putting the partially toothed upper end 20 of the spindle 8 into rotation through the toothed ring 3.
  • the lower end of the spindle 8 carries a suitably shaped support hook 15 for one of the strips 16 of the blind.
  • a resilient tongue 17 which, by abutting against a projection 18 formed in the middle of the profile 12, improves the retention of the box-like body itself within this latter.
  • this tongue is able to guarantee a perfect stability of the box-like body against the inevitable stresses transmitted by the movement of the displacement member.
  • the perfect mirror image symmetry of the section constituting the sliding track allows the box-like bodies to be introduced with the projecting portion 1' facing either the right (with reference to Figures 1 and 3) or towards the left that is to say with the box-like body itself rotated through 180° with respect to its vertical axis.
  • box-like bodies with the toothed ring arranged for right hand movement of the slidable operating bodies 14 can be fitted on the right hand section of a track whilst bodies arranged with the teeth on the left can be fitted to the left hand section of the same track for sliding movement in the opposite sense from that of the right hand section.
