Definitions

  • This invention relates to a display apparatus, and more particularly to apparatus for movably displaying posters or the like.
  • a display apparatus for displaying panels or the like before one or more windows comprising:- a plurality of flexible planar display panels? driven panel carrying means for mounting and carrying said panels at a selected speed along a defined path passing, in use, before at least one said window; driven panel gripping means provided at a selected location on said path to urge a panel arriving at said location generally along the path at another speed greater rhan said selected speed until the panel is past said location; whereby the action of the panel gripping means results in the display of a new panel before a windov;.
  • the apparatus can be set up in a simple manner to swiftly display a new panel at specific time intervals.
  • the apparatus provides an economical and effective way of displaying information to a viewer which is of particular use in the advertising world.
  • the panel carrying means comprises a pair of opposing transit means respectively mounted for movement about a common axis, the transit means including respective panel mounting means whereby panels are mounted to extend between the transit means to be carried along said defined path.
  • the apparatus includes a store means; said transit means having an unloading position on said path whereat the panels are demounted into the store means, and a loading position on said path whereat the panels are mounted from the store means.
  • the loading and unloading of said panels can be achieved alternatively by the action of gravity on the panels or oy spring means being located to urge a panel at the unloading position to demount into the store means.
  • the store means comprises a pair of opposing channels respectively mounted substantially within the boundary defined by said path and connecting between said unloading and loading positions.
  • the transit means can comprise an annular ring located to rotate about the axis whereby said path is substantially circular, the annular ring including said panel mounting means.
  • the transit means can comprise an endless chain means located to move around said defined path, the chain means including said panel mounting means.
  • the circular path is particularly economical in terms of the space required for the apparatus.
  • the use of an endless chain means does allow the shape of the path to be varied so that the apparatus can be used in a more flexible way.
  • the panel mounting means comprises one or more mounts and a respective panel carrying element provided at one end of a panel.
  • the panel carrying element can take many forms.
  • the panel carrying element can comprise a pin member attached to partially extend across a panel, or a rod member spanning between the pair of transit means, or a cable or thread spanning between the pair of transit means, or an elongate planar member spanning between the pair of transit means.
  • the particular element to employ is dependent on the nature of the panel and its size. For example, the use of a cable or thread is particularly convenient for panels extending over 1 metre between the pair of transit means.
  • each panel can include an inner sleeve wherein the panel carrying element moves from one end to the other end of the panel after each passage past said selected location.
  • each panel can include a hook means at either end thereof whereby one hook means at one end is attached to the panel carrying member prior to passage past said selected location and after said passage the hook means at the other end is attached to the panel carrying member.
  • This makes it possible to reverse the side of the panel that passes a window effectively producing double sided display.
  • tne edge portion of the panel arriving at said panel gripping means can be formed so as not to be fully gripped thereby prior to being urged past said location. This can result in slippage of panel which produces wobbling thereof and enhancement of viewer appeal.
  • each said mount is formed to permit limited movement of the panel carrying member along said path under the action of the gripping means and independently of the movement of the transit means. Consequently, just for the interval when the folding problem may occur, the mount allows the panel to advance slightly.
  • the mount comprises a recess generally parallel to the path at said selected location.
  • the panel gripping means preferably comprises a pair of opposing roller means defining a space through which the arriving panels pass, the roller means being rotated at said greater speed.
  • the roller means have a facing of sponge like resilient material so that the panel is effectively gripped.
  • At least one of said roller means can also have located thereon a flat whereat the panel is not gripped. This results in the panel slipping and wobbling thereby enhancing the viewer appeal.
  • the transit means includes cam members located to cause the roller means to temporarily separate for a selected portion of the panel travel along said path substantially at said selected location.
  • the roller means could be biassed together such that the arriving panel briefly separates the roller means
  • the new panel displayed is either the panel just approaching said location or the panel just past said location. Consequently, the way in which the new panel is displayed can be varied according to where the window is provided. Indeed, by having two windows, new panels of ooth types can be displayed. Moreover, as the panel just past the location is released from the gripping means, it flops before the window. This has unexpectedly been found to attract a viewers attention thereby further enhancing the viewer appeal of the apparatus.
  • the panel carrying means moves the panels in a series of indexed steps along said path and the panel gripping means urges said panels along said path at a speed greater than either tne speed of movement during indexed movement or the zero speed after indexed movement.

  • FIG. 9 illustrates an alternative means for driving the 5 annular rings
  • Figure 10 illustrates an alternative channel for carrying the panels.
  • a pair of rotation members 1 are located on a common rotation axis Y a distance X apart.
  • Each rotation member comprises a disc 2 fixedly mounted to a frame (not shown) .
  • a panel carrying means in the form of an opposing pair of annular rings 3 are respectively located around the circumference of the disc and have a geared outer surface so that they can be driven to rotate together in the direction of arrow C about common axis Y.
  • Other forms of drive means can of course be provided.
  • each ring 3 includes four channels or grooves 16 which receive a panel carrying element in the form of a pin 10.
  • the channels 16 in one ring 3 are directly opposite those of the other ring 3 so that opposing pairs of pins 10 carry a panel 11 spanning between the opposing rings 3 as illustrated.
  • the pin members are slidably located in the channels 16 and are fixedly attached to a respective planar display panel 11. Thus, as the rings are rotated together, the panels are carried around a defined annular path.
  • Each disc 2 includes an aperture 4 for receiving a shaft 5 parallel to axis Y.
  • the shaft 5 carries a pair of rollers 6 and is driven by means (not shown) in the direction of arrow A. Assuming that the fixed discs 2 are located whereby the 12 o'clock position is located towards vertical, then the aperture 4 is located at approximately the 9 o'clock position.
  • a further shaft 7 is mounted directly opposite and parallel to the shaft 5, as illustrated in Figures 1 and 4, and carries further rollers 6'.
  • the shaft 7 is arranged to be driven in the direction of arrow B shown in Figure 4, which is in the opposing direction to that of shaft 5.
  • There is a minimal gap 30 between the rollers 6 and the rollers ⁇ ! which is located on the annular path around which the panels travel.
  • the apparatus operates as follows. Referring to figure 4, the apparatus described above is mounted within a housing having a window 8 and 9 on opposite sides of the apparatus. Only three panels are illustrated for clarity.
  • the annular rings 3 are arranged to rotate at approximately one half to two RPK whereas the shafts 5 and 7 have a common rotational speed which rotates rollers 6 and 6' at an angular velocity which is more rapid. Only one roller needs to be rotated if the rollers are in contact. Therefore, as a panel 11 arrives at the rollers 6 and 6', the panel is rotating at 2 RPM (figure 4(a). As the panel 11 passes between the rollers, it is gripped and urged vertically upwards as illustrated in figure 4(b).
  • a suitable cowling 12 can optionally be provided after the rollers in the direction of arrow C so as to urge the looped portion of the panel 11 to fall or flop over towards the axis Y where it encounters an optional support cowling . 13 located to prevent the panel from tangling with other panels (figure 4 (c) .
  • a panel is in view until it arrives at the rollers 6 and 6' and is swiftly removed from sight of the window thereby exposing the next panel in line before it too arrives at the rollers.
  • a panel is in view until the panel that has just passed between the rollers flops down over the cowling 13 under the action of gravity. Consequently, by arranging the geometry of the annular path and the window 9 to be correct, a viewer looking through window S sees the panel suddenly appear.
  • rollers 6 and 6' are described, they can be replaced by rings of rubber or the like mounted to the shafts 5 and 7. Moreover, the shaft 7 can be driven either independently or driven by the shaft 5.
  • the display panel can take many forms.
  • another display panel is shown in Figure 5.
  • This panel includes a slot 14 at least along the side of the panel, although it will be appreciated that the slot may extend through the panel to form an internal sleeve spanning between the rings 3.
  • Posters or the like are mounted in pockets 31 either side thereof. This is advantageous because when the panel II passes between the rollers 6 and 6', the panel itself is urged between the rollers faster than the pin members 1C. Consequently, the pin member 10 slides within the slot 14 until the pin member engages the other end of the panel 11, in effect reversing the mounting.
  • the panel could conveniently comprise a poster itself rather than a transparent carries with the poster mounted therein or printed thereon.
  • FIG. 6 illustrates an alternative embodiment of the display panel wherein a hook element 15 is provided at either end of the panel 11 so that the panel depends from either hook element in alternation.
  • FIG. 7 illustrates an apparatus for temporarily separating the two rollers 6 and 6' at the time the panel passes therebetween.
  • the plate 20 is located outwardly of the rotation members 1 shown in Figure 1.
  • 7ha shafts 5 and 7 pass through apertures 21 formed in a pair of cam members 22 mounted to the plate 20 by fixed points 26.
  • Each member 10 provided on the annular ring 3 includes an immediately adjacent cam disc 24 shown in dotted outline in Figure 7.
  • the cam disc 24 defines the path indicated at 25 in chain dotted outline in Figure 7.
  • Each cam member 22 includes a respective cam surface 23 which is formed such that it is engaged by the cam disc 24 as it travels on path 25 so that the respective cam members 22 pivot about their fixed points 26 in the direction of arrow D shown in Figure 7.
  • the rollers 6 and 6' also separate.
  • the cam surfaces 23/ it is possible to arrange for the rollers 6 and 6' to separate sufficiently to allow the panel 11 to enter the space 30 between the rollers 6 and 6' without interference.
  • the cam members 22 are arranged by suitable urging means (not shown) to return to their original position as illustrated, which position is defined by a pair of stops 27 which can be made adjustable if required. Consequently, the rollers 6 and 6' close on the panel 11 and transfer their rotational speed to the panel to urge it vertically as shown in figure 4(b).
  • the shafts 5 and 7 can be carried on pivotable members which are urged apart by the action of the cam 24 on reciprocal cam surfaces provided on the shafts 5 and 7. Consequently, the action of the cam 24 is again to temporarily separate the rollers 6 and 6' for a selected portion of the panel travel on its annular path.
  • Another alternative is to have the rollers 6 and 6' biassed together by a weak spring so that when the panel or member 10 passes therebetween along the path, the rollers are urged apart temporarily before they grip the panel. Indeed,the degree of gripping of the panel can produce an added advantage.
  • FIG 8 illustrates an alternative annular ring employed with the present invention.
  • the annular ring 3 has four equidistant apertures 18 formed for receiving the members 10, in this case they are rods.
  • a channel 19 is formed in the fixed disc 2 to extend across an arc at an angle inclined to horizontal.
  • a plurality of rods 10 are located in the channel 19, each mounting a panel 11.
  • a simplified apparatus which can store a substantial number of display panels. This increase in storage capacity allows a greater number of panels to be displayed which thereby enhances the appeal of the apparatus to a viewer.
  • suitable spring means can be employed to assist in the loading and unloading of the apertures 18.
  • the embodiment described w ⁇ ith reference to figure 8 is advantageous because of the added number of panels that can be employed.
  • the ring 3 includes an outwardly facing slot 40.
  • An outer ring 41 is driven in the direction of arrow C and includes a respective drive pin 42 engaging the slot 40.
  • the pin 42 acts on the slot 40 to drive the ring 3.
  • each aperture 18 comprises a channel 36 which overcomes the above problem of folding on passing of a panel between the rollers 6 and 6', but includes only a small entrance hole 35 sufficient to allow one member 10 to enter. Thereafter, the slot has an axial facing wall 37 which effectively closes the channel 19. Consequently, single loading of the members 10 into the aperture 18 is assured whilst at the same time allowing circumferential movement to avoid the folding problem mentioned above.
  • the present invention encompasses many alternatives which will be apparent to a person skilled in the art.
  • the present invention is described with reference to panel carrying means in the form of a rotating annular ring, the ring could be indexed.
  • the indexing by arranging the indexing correctly, it has been found that the problem of folding the panels mentioned above is overcome.
  • the rollers it is important in one embodiment for the rollers to rotate at a speed greater than the panel movement at that time.
  • the rollers are temporarily separated during indexing of the ring and only closed after that movement is complete, the speed of the rollers can be reduced and need only be sufficient to urge the panel past the location of the rollers.
  • the carrying means could comprise a chain with appropriate panel carrying means. This has the advantage that the path about which the panels are carried does not have to be annular.
  • the panel mounting means have primarily been described as pin members or rods, it is possible to employ an elongate planar member or fixtures for retaining a wire, cable or thread to which the panel 11 is attached.
  • the pin member could also include a gripping means to grip a mount a panel, for example in the form of a poster. It will also be apparent that the direction of rotation indicated by arrows A, B, and C could be reversed.

Abstract

Est décrit un appareil permettant l'affichage mobile de placards publicitaires ou similaire. Une paire de bagues annulaires (3) opposées sont respectivement situées de manière à être entraînées pour tourner à une vitesse de 2 t/mn ensemble dans le sens de la flèche C autour d'un axe commun. Des paires opposées d'axes (10) sont disposés coulissants dans des canaux ménagés dans chaque bague et portent un panneau d'affichage (11) s'étendant entre les bagues autour d'un chemin annulaire défini. Une paire de rouleaux (6, 6'), entraînés à une vitesse plus rapide dans le sens des flèches A et B respectivement, sont situés avec un espacement minimal (30) sur le chemin défini. Un panneau arrivant au niveau des rouleaux pénètre dans cet espacement et est rapidement amené entre les rouleaux. Il forme une boucle et rencontre un capotage (12) ménagé après les rouleaux, lequel amène la portion bouclée à basculer en direction de l'axe Y où il rencontre un capotage de support (13). Par voie de conséquence, un spectateur regardant dans une première fenêtre (8) voit un panneau jusqu'à ce qu'il arrive au niveau du rouleau et soit rapidement soustrait à la vue, faisant apparaître le panneau suivant en ligne avant que celui-ci aussi n'arrive au niveau des rouleaux. Un spectateur regardant dans une seconde fenêtre (9) voit un panneau jusqu'à ce que le panneau qui vient de passer entre les rouleaux bascule subitement par-dessus le capotage sous l'effet de la gravité.
