Definitions

  • the invention relates to a device for the successive display of different images, for example, in the form of pictures, texts and the like, comprising a frame and image members adapted to turn about axes of rotation and journalled in said frame, said image members having a plurality of image faces at an angle to one another and being adjustable in the frame in a manner such that each time a plurality of image faces of adjacent image members display the desired image, each image member comprising a plurality of lamellae extending at least substantially parallel to the axes of rotation and being provided on both sides with an image face, said lamellae being arranged in the image member so as to be rotatable through 180° about their longitudinal axes and being supported by supporting members forming part of the image member and being rotatable about the axis of rotation of the image member, there being provided setting means with the aid of which lamella is turned about its longitudinal axis during the turn of the image member concerned.
  • French Patent Specification 433,182 proposes a construction of a similar device of which each lamella is subdivided into two parts which are relatively slidable in the direction of width of the lamella. This brings about a still more complicated mechanism for turning the lamellae and for setting the parts of the lamellae relatively to one another.
  • the lamellae are capable of reciprocating with respect to the supporting members in a direction away from the axis of rotation and in a direction towards the axis of rotation, whilst guide means are provided with the aid of which each lamella as a unit is guided between two consecutive positions in which it is located on the front side of the device, gradually in a direction away from the axis of rotation and subsequently in a direction towards the axis of rotation, whilst the lamellae and the frame of the device are provided with relatively co-operating cams and/or stops causing a turn of the lamella concerned about its longitudinal axis during the reciprocatory movement of the lamella with respect to the axis of rotation.
  • the means for displacing and turning the lamellae can be constructed in a simple manner and the lamellae, without the need for composing them from several parts, can have such a width that the lamellae forming a picture or the like getting into view in neighbouring image members adjoin one another at least substantially.
  • the device embodying the invention comprises a frame 1 in the form of a framework accommodating a plurality of image members 3 adapted to turn about vertical, relatively parallel axes of rotation 2.
  • the image members 3 can turn about vertical axes of rotation 2, it will be obvious that the axes of rotation may be arranged, as an alternative, at a different angle, for example, in horizontal positions.
  • the shafts 4 of the image members arranged coaxially with the axes 2 can be simultaneously turned with the aid of a driving motor 5 and a transmission mechanism 6.
  • image member of the kind schematically shown in Fig. 2 comprises three lamellae 7, 8 and 9, which are provided at their ends with stub shafts 10, which are coaxial with the longitudinal axes of the lamellae extending parallel to the axes of rotation 2 so that the lamellae are capable of turning about their longitudinal axes in the image member 3 concerned.
  • the stub shafts 10 fastened to the lower and top ends of the lamellae 7 and 9 are arranged in slots 11 in plate-shaped catches 12 fastened near the top and bottom ends of the lamellae to the shaft 4. From Fig.
  • each display member 3 At least near one end of each display member 3 a guide curve 13 is stationarily arranged for the stub shafts 10 located at the end concerned, the arrangement being such that the stub shafts 10 concerned will move through the curve during the turn of the image member 3 concerned.
  • the lamella 7 extends parallel to the front side of the device. From this Figure it will furthermore be apparent that the curve or groove 13, in which the ends of the pins 10 are moving during operation, is concentric by its part 14 directed towards the front side of the device with the shaft 4 through an angle of about 210°.
  • the ends of the part 14 of the curve 13 concentric with the rotary shaft 4 are adjoined by parts 15 and 16 being at least substantially at right angles to the front side of the device, which parts communicate with one another through a curved part 17 of the groove.
  • parts 15 and 16 being at least substantially at right angles to the front side of the device, which parts communicate with one another through a curved part 17 of the groove.
  • four stops 18 are fixed in the device so that these stops 18 are arranged symmetrically to a plane at right angles to the front side of the device and going through the axis of rotation 2 of the image member 3 concerned.
  • Each lamella is provided at the end concerned with a cam 19 co-operating with the fixed stops 18 concerned.
  • this lamella When the lamella has attained the position 7", this lamella will again lie at the front of the device after a next turn of the image member 3 through an angle of 120°. Owing to the turn described of the lamella 7 about its longitudinal axis the image face A first visible is replaced by the image face B at the front of the device.
  • the lamellae are not only turned about their longitudinal axes but also shifted with respect to a central shaft 4 of the image member, it remains possible to maintain a compact construction of the device, whilst the image surfaces visible at the front on neighbouring lamellae at least substantially join one another by their longitudinal edges.
  • the lamellae may have a different shape than the rhombic form shownin the Figures, they may be rectangular or elliptical.
  • the drive of the lamellae may be constructed in any desired manner. In the drive shown all image members are turning in the same direction, but as an alternative a drive is conceivable in which adjacent image members turn in opposite senses. It will be obvious that also in these cases the construction embodying the invention can be used by correctly arranging the various image faces on the various lamellae.
