  • the tilt mechanism for the slats can be provided in a number of ways of which a single, presently preferred embodiment will be described in the detailed description of the invention. It is emphasised that although the tilt mechanism of the present invention is described specifically in connection with a system comprising a pantograph mechanism, the tilt mechanism according to the invention could also be applied in other systems of slats, which are to be tilted, for instance other forms of shutters or Venetian blinds, which do not comprise the pantograph mechanism described in the present specification.

  • FIG 1 there is shown an embodiment of a shutter according to the invention generally designated by reference numeral 1 and comprising a at least partially hollow frame 2 comprising juxtaposed sidepieces 2' and top and bottom portions 2",
  • an elongated opening or recess 14 serving as guide tracks for the rotational axes of the individual slats is provided extending longitudinally in the sidepieces 2' to such an extent that the slats 3 (or rather their rotational axes) can be displaced sufficiently in these to be able to cover the inner region of the frame or a desired portion hereof
  • the rotational axles 4 of the individual slats 3 are passed through these elongated openings/guide tracks 14 and into the hollow interior of the frame.

  • FIG 3 only shows one of the sidepieces 2 ! of the frame 2
  • the juxtaposed sidepiece can be designed similarly, but according to a preferred embodiment of the invention the juxtaposed sidepiece comprises only the pantograph mechanism, while the tilt mechanism is only provided in one of the sidepieces.
  • Figure 3 shows the guide track or longitudinal opening 14 through which the rotational axles 4 of the individual slats 3 are passed
  • the said pantograph mechanism designated by reference numeral 5 which mechanism as shown is composed of a series of cross-sections 5', through the central, crossing part of which the rotational axles 4 of the slats 3 are passed, so that these are freely rotatable in the crossings of the pantograph mechanism.
  • a lever 8 is located, said lever at the end of the arm that is positioned farthest away from the rotational axle being provided with a first pin or roller 9.
  • the lever 8 When the lever 8 is tilted as shown by the arrows B, the corresponding slat is tilted
  • said first pin or roller 9 is in engagement with a groove 10 of substantially the same width as the diameter of the pin or roller 9.
  • the groove 10 is provided in a bar 1 1 extending in the longitudinal direction of the sidepiece 2', which bar 11 can be displaced both longitudinally and laterally in the sidepiece 2'
  • the lateral displacement is indicated by the arrows A in figure 3
  • the bar 1 1 In order to attain the simultaneous displacement longitudinally and laterally in the sidepiece 2', the bar 1 1 is on the face hereof away from the groove 10 provided with another pin or roller 13, which can be displaced in an oblique groove or track 12 provided in the outer face of the sidepiece 2 1 .
  • the oblique groove or track need not necessarily be visible from the outside of the sidepiece 2, or be provided in the sidepiece at all, but may be provided in a separate member, which may be displaceably connected to the inner face of the sidepiece in such a manner that it is not visible from the outside.
  • the displacement of the second pin or roller 13 in the groove 12 thus provides the simultaneous displacement of the bar 1 1 longitudinally and laterally in the sidepiece 2', and thus results through the engagement between the first pin or roller 9 on the lever 8 and the groove 10 in the bar 1 1 in the desired tilting of the slats 3-
  • the tilt function will be operative regardless of where the individual slats are located within the frame.
  • the groove 12 can in principle extend at any angle ⁇ between 0 and 90 degrees relative to the longitudinal axis of the sidepiece 2', although from a practical point of view it has been shown to be advantageous if this angle is in the order of magnitude of 30 degrees.
  • levers 8 and hence the slats even in the most collapsed state of the pantograph mechanism can be tilted over the largest possible angular interval and in order to ascertain that the Severs 8 can be made as long as the hollow interior of the sidepieces allows, it is advantageous to design the levers as shown in figure 3a, I e. with a bended middle section joining two substantially parallel distal sections receiving the rotational axle 4 of the slat and the tip or roller 9, respectively.
  • the pantograph mechanism 5 will in principle cause the distance between the points where the rotational axles 4 of the slats 3 are passed through the crossings to remain the same for all slats for any extension of the pantograph mechanism
  • the pantograph mechanism is retracted from its maximally extended state, where the slats cover the whole of the inner region of the frame, to a more collapsed state, the same distance will in principle always be provided between any neighbouring slats regardless of where in the system of slats these are located.
  • the slats thus remain evenly distributed over that portion of the inner region of the frame, which is covered by the slats
  • reference numeral 15 generally designates a fixed connection to the relevant part of the frame. As appears, one distal crossing point 15 of the pantograph mechanism 5 will in all of the shown embodiments be fixedly connected to the frame by attachment means allowing a corresponding slat to tilt over the desired angular interval.
  • FIG 4a shows a first embodiment of drive means for the pantograph mechanism
  • the pantograph mechanism is in suspended form 15 (the direction UPWARD is indicated in the figure) and two lift cords 16 are attached to the lowermost crossing at 17,
  • the lift cords 16 may be passed through suitable guide means 18 at the other crossings as shown.
  • the lift cords 16 will be connected to suitable drive means (not shown in the figure) provided in the top portion 2" of the frame, for instance comprising a motor, which via a suitable transmission drives a drum for winding/unwinding of the lift cords.
  • suitable drive means not shown in the figure
  • the lift cords 16 will retract (collapse) the pantograph mechanism in an upward direction and conversely the force of gravity acting on the slats will be utilised for the downward movement of the slats
  • FIG 4b an alternative way of operating the system is shown, the system still being suspended from a fixed point 15 and thus for the downward movement of the siats still at least to some extent relying on the action of gravity on the siats.
  • the two lift cords shown in figure 4a are replaced by a single lift cord 19, one end of which is attached to the top portion 2" of the frame and which via suitable guide means 20 is passed over a spool or pulley 21 attached to the lowermost crossing, from which the iift cord 19 via said guide means 20 is passed to a drive mechanism, for instance of the kind described in connection with figure 4a.
