Definitions

  • the invention relates to a device for displaying illustrations, texts or the like provided with a frame and with a plurality of display means which are rotatable about parallel axes of rotation, said display means comprising a few surfaces extending at least substantially parallel to said axes of rotation and including an angle with each other, said surfaces being provided with parts of the illustrations, texts or the like to be formed, whilst wheel-shaped driving means are disposed near ends of said display means, which wheel-shaped driving means can be rotated about their central axes extending transversely to the axes of rotation of the display means in order for said display means to be rotated, whereby said wheel-shaped means co-operate with pins secured to the ends of said display means.
  • a device of this type is known from European Patent Application No. 0 539 308.
  • Various illustrations, texts or the like can be displayed in succession with such a device by rotating the display means.
  • the object of the invention is to provide a device wherein the above drawbacks are avoided.
  • this object is accomplished in that pins secured to a display means extend parallel to the axis of rotation of the respective display means and are disposed in regularly spaced-apart relationship in a circle extending concentrically about the axis of rotation of the display means, whilst the wheel-shaped means is provided with a projecting nose, on either side of which passages are present in said wheel-shaped means, all this in such a manner that when the wheel-shaped means is rotated, a pin is engaged by the nose so as to effect a rotation of the respective display means, whereby two pins are each guided through a passage from one side of said wheel-shaped means to another side of said wheel-shaped means.
  • One embodiment of the device according to the invention is characterized in that said wheel-shaped means is provided with two parallel flanges positioned on the same side of said nose, said flanges near said nose being provided with passages for guiding a pin from a side facing said nose of the flange located near said nose to a side facing away from said nose of the other flange, and vice versa.
  • the nose is in engagement with said pins only over a particular part of a revolution of the wheel-shaped means.
  • the flanges provide an accurate guiding and positioning of the pins positioned between the flanges.
  • Figure 1 is schematically shows one end of a display means with pins secured thereto and a wheel-shaped means co-operating with said pins.
  • Figure 2 is a larger-scale view of a wheel-shaped means.
  • Figure 3 is a side view of Figure 2.
  • Figure 4 is a sectional view of Figure 3, along line IV-IV in Figure 3.
  • Figures 5a-5g schematically show relative positions, seen from the central axis of the wheel-shaped means in the direction of the outer circumference of the wheel-shaped means, which pins secured to a display means and the wheel-shaped means take up with respect to each other when the wheel-shaped means is rotated in order to effect a rotation of the display means.
  • Figure 6 is a perspective view of a second embodiment of a device according to the invention.
  • Figure 7 is a perspective view of the device shown in Figure 6, in another position thereof.
  • Figure 8 is a larger-scale view of a wheel-shaped means according to the invention shown in Figure 6.
  • Figure 9 is a side view of Figure 8.
  • Figure 10 is a sectional view of Figure 8, along line X-X in Figure 8.
  • Figures 11A-G schematically show relative positions, seen from the central axis of the wheel-shaped means in the direction of the outer circumference of the wheel-shaped means, which pins secured to a display means and the wheel-shaped means take up with respect to each other when the wheel-shaped means is rotated in order to effect a rotation of the display means.
  • Figure 1 shows one end of a display means 1, which is provided with three surfaces 2 including an angle with each other, which surfaces 2 form an equilateral triangle, seen in sectional view of the display means 1.
  • a plurality of such display means are arranged in parallel relationship, and are journalled in supports 3 in such manner as to be rotatable about axes of rotation extending in the longitudinal direction of the display means, said supports 3 forming part of a frame of a device for displaying illustrations of which display means 1 forms part.
  • the surfaces 2 are thereby intended for being provided with illustrations, texts or the like.
  • a shaft 4 is mounted on one end of display means 1, the central axis of said shaft coincides with the axis of rotation of display means 1.
  • a disc 5 extending perpendicularly to shaft 4 is mounted on the end of said shaft 4.
  • Three pins 6 - 8 are mounted on said disc, on the side facing away from shaft 4, said pins extending parallel to shaft 4 and thus parallel to the axis of rotation of display means 1.
  • the pins are thereby arranged at regular angular distances apart on a circle extending concentrically about the axis of rotation of display means 1.
  • Said pins co-operate with a wheel-shaped means 9 illustrated in more detail in Figures 1 - 4.
  • Said wheel-shaped means comprises a hub 10, in which a (preferably unround) hole 11 is formed, said hole being hexagonal in the illustrated embodiment.
  • a plate-shaped disc 12 extending perpendicularly to the central axis of hole 11 is mounted on said hub, said disc extending through approximately 270° about the central axis of hole 11.
  • Mounted on the outer circumference of said disc is a rim or strip 13 extending concentrically about the disc, the ends of which rim or strip project slightly beyond the ends of plate 12.
  • a radially extending arm 14 is secured to hub 10, which arm divides the angle between boundary edges 15 and 16 of plate 12 in half, seen in the longitudinal direction of the central axis of hub 10.
  • a plate-shaped means or nose 17 is mounted on the free end of arm 14. As will be apparent from Figure 3, said plate-shaped means or nose 17 is curved in the longitudinal direction of the central axis of hub 10, in such a manner that said plate-shaped means or nose 17 extends concentrically about the central axis of hub 10, whereby the spacing between the hub and the outer and the inner boundary surfaces of nose 17 is the same as the spacing between the hub and the inner and the outer boundary surfaces of rim 13.
  • the width of the part of nose 17 positioned between the facing ends of rim 13 gradually decreases.
  • the boundary edges 18 and 19 of rim 13 facing towards nose 17 thereby extend more or less parallel to the boundary edges of said nose positioned opposite said boundary edges 18 and 19.
  • passages 20 and 21 are formed on either side of nose 17, between the boundary edges 18 and 19 of said rim 13 and the opposite boundary edges of nose 17, the longitudinal axes of said passages including an angle deviating from 90° with an imaginary plane extending through the central axis of hub 10 and the longitudinal axis of arm 14, whereby said passages 20 and 21 extend in opposed oblique directions with respect to said imaginary plane.
  • a wheel-shaped means of this kind is disposed beside disc 5, in such a manner that the central axis of hub 10 is intersected perpendicularly by the extension of the axis of rotation of display means 1.
  • pins 6 and 8 will be positioned on one side of rim 13 of wheel-shaped means 9 and pin 7 will be positioned on the other side of said rim 13, as a result of which said wheel-shaped means 9 prevents rotation of display means 1 about its axis of rotation.
  • the wheel-shaped means 9 will be rotated so as to cause rotation of the display means about its axis of rotation, as is indicated by means of arrow A in Figure 5.
  • Said diagrammatic Figure 5 shows the illustrated parts as seen from the central axis of wheel-shaped means 9 in the direction of the outer circumference of the wheel-shaped means, in particular in the direction of nose 17, as is indicated by arrow B ( Figure 3).
  • the part of nose 17 that projects beyond rim 13 in a direction perpendicularly to the central axis of wheel-shaped means according to arrow B will come into contact with pin 7, which will cause display means 1 to rotate in the direction according to arrow B, as is indicated in Figure 5b .
  • the wheel-shaped means 9 of display means 1 disposed in side-by-side relationship in the device may be mounted on a common unround shaft inserted into holes provided in the wheel-shaped means.
  • the unround shaft is preferably twisted about a central axis extending in its longitudinal direction, so that a more or less "wavy" rotating movement of the display means 1 disposed in parallel relationship is effected, since it will be possible in a simple manner in that case for the pins 6-8 of successive display means to be positioned at different parts of the continuous part of the respective rim 13 in the position of rest.
  • FIGS 6 - 11 show a second embodiment of the device according to the invention, which is provided with another wheel-shaped means 25.
  • Said wheel-shaped means comprises a hub 10, in which a (preferably unround) hole 11, a hexagonal hole in the illlustrated embodiment, is formed.
  • Two flanges 26, 27 extending transversely to the central axis of hole 11 are secured to said hub 10, which flanges extend parallel to each other.
  • An annular guide slot 28 is located between flanges 26, 27.
  • a radially extending arm 14 is secured to the hub 10.
  • a plate-shaped means or nose 17 is secured to the free end of arm 14.
  • Nose 17 is configured to extend concentrically about the central axis of hub 10, whilst the tip of the nose is directed towards flanges 26, 27.
  • Flanges 26, 27 are provided with passages 29, 30 on either side of nose 17.
  • the tip of nose 17 extends to within passage 29 of flange 26.
  • pins 6, 8 are positioned within slot 28 and pin 27 is positioned on a side facing nose 17 of the flanges 26.
  • Pins 6, 8 are precisely maintained in the position shown in Figure 6 by the flanges 26, 27 bounding slot 28.
  • By rotating a shaft 31 extending through slot 11 in a direction indicated by arrow A the various positions A - G shown in Figure 11 are successively obtained until, after a single revolution of shaft 31, pins 7 and 8 are positioned within slot 28 and pin 6 is positioned on a side of flange 26 facing nose 17.
  • the display means connected therewith has at the same time been tilted through 120°.
  • pin 8 is led back to slot 28 via passage 30 as a result of the further pivoting of the nose in the direction indicated by arrow A, whilst pin 7 is moved into said slot via passage 29 (see Figures 11E-F).
  • pins 7 and 8 are positioned within slot 28.
