Definitions

  • This invention relates to a shutter blind unit having novel and improved utilities and advantages over prior venetian blind type units.
  • objects of the invention include the obtaining of the benefits of the types discussed above together with other novel advantages.
  • an object of the present invention include the obtaining of a compact track unit of shutter blinds having aesthetically pleasing appearance while being easily operable and being of few and uncomplicated and easily assembled elements.
  • Another object is to obtain a revolvable shutter blind which closes tightly by freedom to rotate a full 180.
  • Another object is to obtain a shutter blind which overlaps a lower shutters edge such as to totally block line of sight and the passage of light.
  • Another object is to' obtain a shutter blind which overlaps a lower shutters edge irrespective as to the di rection in which the upper shutter is turned to close the shutter.
  • Another object is to provide an easy and uncomplicated locking mechanism for locking blinds in any desired point of elevation.
  • Another object is to obtain a simple and effective mechanism for retaining against gravity raised shutters at desired heights together with ease of raising and low- I tion in angle on a fixedly mounted axis extending preferably through the respective opposite slots and each extended axis including laterally radially outwardly extending axis structure as a lever having pivotably attached to an outer portion of the lever structure linking elements linking together outer portions of upper and lower lever structures of upper and lower axes of the various horizontally extending shutters, and there being included retainer means for securing the shutters at any desired point to which they have been raised, and preferably also there being lock elements for securing the shutters imovably in predetermined positions of lowered or partially raised state or the like.
  • overlapping seating structure between the adjacent edges of the shutter slats for obviating the passage of any light and also preferably a special slidable slat which brings about overlapping irrespective of the direction of tilt by virtue of the slat being slidable by the pull of gravity, to slide on a shutter frame.
  • light between shutter ends and the support upright slot structures is obviated by shoulder structures extending inwardly into the window space along the upright length of each of the support upright slot-defining structures to thereby block-out and thus obviate any possibility of light therethrough when the shutters are down and/or closed.
  • cranks and/or cords or the like to raise and/or lower the blinds, or alternatively the raising may be by mere manual adjustment of the slats upwardly and downwardly as desired.
  • a plastic or other suitable strip having a flexible edge, lineally along both slots extending into the slots sufficiently, or at least into the path of the oppositely extending shutter axes sufficiently as to press against the respective axes to bias the axes against the opposite walls of the respective slots to thereby prevent the axes from sliding downwardly by the pull of gravity on the mass of the shutter structures, but being typically sufficiently flexible as to yield to light pressure or force serving to slide the axes along the respective slots.
  • the axes there are slanted notches in the face of the wall on one or the other side of the slot such that the axes may be seated therein at any desired level or height as a means of securing the shutters at that height, or as a means of lowering from the top the shutters to a selected desired point.
  • the notches are along a separate strip mounted in a biased state against the respective axes and having lever and handle structural elements for relieving pressure of the spring-biased notched strip away from the respective slots out of the paths of the axes thereby allowing the shutters to be raised and/or lowered.
  • the connector includes two links pivotably interconnected to one-another at one end of each, and at the remaining opposite ends of the respective links, being connected each pivotably to the lever arms being interconnected by the connector, the intermediate pivotable link action permitting a full freedom of tilt of the respective tilt lever arms in the tilting angularly of the respective shutter slats.
