Abstract
Description
- Device for successive display of different images.
- 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 1800 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 each lamella is turned about its longitudinal axis during the turn of the image member concerned.
- From British Patent Specification 1,551,230 such a device is known in which the lamellae are turned about their longitudinal axes occupying a fixed position in the image member. In order to allow a turn of a given lamella through 1800 neighbouring lamellae have to be turned to and fro, which involves a comparatively complicated driving mechanism for the lamellae. Apart therefrom it will not be possible in practice to use lamellae of such a width that the lamellae of neighbouring image members coming into view adjoin one another at least substantially, since with such a broad design of the lamellae the lamellae of a given image member can practically not be turned one along the other.
- In order to obviate this inconvenience French Patent Specification 433,182 proposes a construction of a similar device in 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.
- Due to the complication of the known constructions they are not only expensive, but also highly susceptible of wear so that maintenance is also expensive.
- According to the invention 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 toward the axis of rotation, whilst the lamellae and the frame of the device are provided with relatively co-ope= rating 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.
- By using the construction embodying the invention a simple design of the device can be obtained in which 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 invention will be described more fully hereinafter with reference to the accompanying Figures which schematically show an embodiment of the construction in accordance with the invention.
- Fig. 1 is a front view of part of a device embodying the invention.
- Fig. 2 is a plan view of an image member comprising three lamellae.
- Fig. 3 is an elevational view of a catching member for the lamellae.
- Fig. 4 is an elevational view of a guide curve for the lamellae in which the turn of a lamella about its longitudinal axis is represented in different positions.
- Referring to Fig. 1, 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 ofrotation 2. Although in the embodiment shown theimage members 3 can turn about vertical axes ofrotation 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 theaxes 2 can be simultaneously turned with the aid of a drivingmotor 5 and atransmission mechanism 6. - In the embodiment shown an image member of the kind schematically shown in Fig. 2 comprises three
lamellae 7, 8 and 9, which are provided at their ends withstub shafts 10, which are coaxial with the longitudinal axes of the lamellae extending parallel to the axes ofrotation 2 so that the lamellae are capable of turning about their longitudinal axes in theimage member 3 concerned. Thestub shafts 10 fastened to the lower and top ends of thelamellae 7 to 9 are arranged inslots 11 in plate-shaped catches 12 fastened near the top and bottom ends of the lamellae to theshaft 4. From Fig. 3 it will be apparent that the slots relatively off-set through an angle of 120° about thecentre line 2 of theshaft 4 extend in a radial direction with respect to thecentre line 2 of theshaft 4. Therefore, thestub shafts 10 are capable of sliding to and fro in theslots 11 with respect to theshaft 4. - At least near one end of each display member 3 a
guide curve 13 is stationarily arranged for thestub shafts 10 located at the end concerned, the arrangement being such that thestub shafts 10 concerned will move through the curve during the turn of theimage member 3 concerned. Referring to Fig. 4 thelamella 7 extends parallel to the front side of the device. From this Figure it will furthermore be apparent that the curve orgroove 13, in which the ends of thepins 10 are moving during operation, is concentric by itspart 14 directed towards the front side of the device with theshaft 4 through an angle of about 210°. The ends of thepart 14 of thecurve 13 concentric with therotary shaft 4 are adjoined byparts 15 and 16 being at least substantially at right angles to the front side of the device, which parts communicate with one another through acurved part 17 of the groove. Near saidcurved part 17 of the groove fourstops 18 are fixed in the device so that thesestops 18 are arranged symmetrically to a plane at right angels to the front side of the device and going through the axis ofrotation 2 of theimage member 3 concerned. Each lamella is provided at the end concerned with acam 19 co-operating with thefixed stops 18 concerned. - From Figs. 2 and 4 it will be apparent that when an image member is turned with the aid of the driving
motor 5 through 120°, thelamella 7 will get into the position 7' shown in Fig. 4, whereas the lamella 9 gets at the front side of the device. Upon a further turn of the image member thestub shafts 10 fastened to thelamella 7 are compelled to move through thegroove 13, whilst the stub shafts concerned are displaced in theslots 11. Thecam 19 fastened to thelamella 7 will co-operate with thestops 18 so that , as is shown in Fig. 4, thelamella 7 is gradually turned through an angle of 120° about its longitudinal axis into theposition 7". When the lamella has attained thepostion 7", this lamella will again lie at the front of the device after a next turn of theimage member 3 through an angle of 120°. Owing to the turn descirbed of thelamella 7 about its longitudinal axis the image face A first visible is replaced by the image face B at the front of the device. - During operation, when the
image members 3 are turning, all lamellae are turned about their longitudinal axes and in the embodiment shown in total six different image faces will be consecutively displaced on the front side of the device. - By using the turning mechanism descirbed above in which 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 in neighbouring lamellae at least substantially join one another by their longitudinal edges. - As a matter of course, many variations and/or supplements are possible within the spirit and scope of the invention. For example, the lamellae may have a different shape than the rhombic form shown in the Figures, whey 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.
- The figures used in the claims are only meant to explain more clearly the intention of the invention and are not supposed to be any restriction concerning the interpretation of the invention.
