Definitions

  • the present invention relates to automatically changeable display signs.
  • the shuttle display apparatus of the present inven­tion is characterized by a base having a plurality of later­ally extending tracks which are connected together at their opposite ends by means of shuttle tracks.
  • a plurality of pairs of display panels are racked together on individual carriages traveling in such tracks such that the display panels are arranged in columns on the lateral tracks and may be sequentially advanced from one side to the other along the lateral tracks, shuttled between such tracks and then sequen­tially retracted to the opposite side of the tracks.
  • composite displays on the sides of the panels exposed simultaneously to one side or the other of the base may carry a composite message for observation by viewers viewing the display device.
  • the shuttle display apparatus of the present inven­tion includes, generally, a base 21 having formed therein first and second pairs of lateral tracks 23, 25, 27 and 29 (FIG. 3) joined together on their opposite ends by means of respective shuttle tracks 31 and 33 (FIG. 6).
  • Carried in the tracks 23, 25, 27 and 27 are first and second racks of car­riages, generally designated 41 (FIG. 3), which mount respec­tive vertical display panels 47 - 69 (FIG. 1).
  • a drive mech­anism, generally designated 71 (FIG. 3) is operative to selectively advance the panels 47 - 55 of the first rack of panels forwardly in the tracks 23 and 25 and to selectively shuttle the front panel, as for instance panel 55, from the lefthand rack as viewed in FIG.
  • the base 21 may be constructed of any desirable material and is preferably constructed in modular form such that modules of such base may be connected together in end-to-­end relationship to thereby enable display of multiple pairs of columns of panels 47 - 66.
  • the lateral tracks 23, 25, 27 and 29 are in the form of grooves (FIG. 3) formed in the top wall of the base 21, each pair being separated by means of respective hollow boxlike raised plat­forms having top walls 81 and 83 which form tray-receiving respective chambers 82 and 84 thereunder as disclosed herein­after.
  • the carriages 41 are in the form of upwardly opening channels 85 mounted on respective cylindrical followers 89 received in the respective tracks 23, 25, 27 and 29 and riding on respective roller bearings 30 (FIGS. 1, 3, 4 and 6).
  • the bottoms of the tray chambers 82 and 84 are closed by means of respective bottom walls 92 and 94 (FIGS. 3 and 4) formed centrally with short laterally projecting through slots 96 and 98.
  • Received within the chambers 82 and 84 and riding on the bottom walls 92 and 94 are respective escort trays generally designed 102 and 104 (FIGS. 5 and 6).
  • the escort trays 102 and 104 are formed in the four corners with respective upwardly and downwardly opening ball bearing cavities which receive respective ball bearings 106 (FIGS. 5 and 6) that project from the bodies of such trays to ride on the respective bottom walls 92 and 94 and to engage the top walls 81 and 83 to carry and guide such trays in their lateral travel.
  • the trays 102 and 104 are formed at their respective back and front ends (FIGS. 5 and 6) with respective laterally projecting tongues 108 and 110 aligned with the floor of the shuttle tracks 31 and 33.
  • the tongues 108 and 110 are turned upwardly at their respective outer extremities to form respec­tive longitudinal pushers 112 and 114 which serve to push the followers 89 and selectively from the shuttle track to the lateral tracks 23 - 29 as will be described hereinafter.
  • the tongues 108 and 110 cooperate with the respective pushers 112 and 114 when the trays 25 and 27 are in their extended positions to form respective segments of the shuttle tracks 31 and 33 such that the followers 89 may travel longi­tudinally to their respective positions aligned with the lateral tracks 23, 25, 27 and 29.
  • a T-shaped bell crank mounted within the base 21 and forming a part of the drive 71 is a T-shaped bell crank, generally designated 101 (FIG. 8) having its lateral arm 103 connected with an elec­ tric solenoid 105 (FIG. 3) and biased to the right as viewed in FIGS. 3 and 5 by means of a compression coil spring 107.
  • Diametrically oppositely extending bell crank arms 109 and 111 are formed on their distal ends with respective forks which receive respective vertical drive pins 119 and 121 which project upwardly through the lateral slots 96 and 98 (FIG. 3) formed in the bottom walls 92 and 94 to drive the respective trays 102 and 104.
  • the bell crank 101 is carried freewheeling on a powered axis 125 (FIG. 8) which also mounts an external ring gear 131 sandwiched between such bell crank and the bottom walls 92 and 94.
  • the opposite sides of the ring gear 131 mesh with gear racks formed on the inside of vertical flanges of angle shaped draw bars, generally, designated 133 and 135, (FIG. 6), carried slidably on the opposite lateral edges of the base.
  • the draw bars 133 and 135 are in the form of angles held slid­ably in position on the base 23 by means of respective hori­zontal hold down slats defined by longitudinal inturned lips 134 and 136 formed by the opposite sides of a cover defining the housing for the base 21.
  • the right and left racks of carriages 41 are formed by six carriages.
  • the horizontal flanges of the draw bars 133 and 135 project inwardly and overlie the pushers 112 and 114 to terminate in horizontally spaced apart edges 138 and 140.
  • the confronting edges 138 and 140 of such horizontal flanges are spaced apart a distance substantially equal to the combined major diameters of the followers 89 such that such edges will serve to hold such followers, and consequently the panels 47 - 69, firmly in position as described hereinafter.
  • the horizontal flanges of the respective draw bars 133 and 135 are formed on the inter­ior edges 138 and 140 with respective inwardly opening receiv­ing notches 141 and 143 and 142 and 144 spaced longitudinally apart a distance corresponding with the distance between the pairs of tracks 23 - 25 and 27 - 29 and having a depth suffi­cient to receive therein approximately one-half the cross section of the followers 89 (FIG. 11).
  • This enables a pair of such followers to move forwardly from the pairs of tracks 23 - 25 into their loading position in the shuttle track 33 and rearwardly from the pairs 27 -29 into the shuttle track 31 when such notches are registered with the respective pairs of tracks.
  • the notches are formed along their respective one sides with chamferred leading edges 160, 162, 164 and 166.
  • step motor 51 (FIG. 7) having its armature coupled with the drive pin 125 which is, in turn, keyed to the ring gear 131 by means of a trans­verse key 146.
  • Reciprocation of the ring gear 131 serves to reciprocate the draw bars 131 and 135 in opposite direction from a locked or holding position to their loading positions registering the notches 141 - 144 with the respective lateral tracks 23 - 29 to receive the followers 89 and shuttle them to the opposing pair of tracks for receipt therein.
  • the ends of the draw bars 133 and 135 are formed with a tongue and clevis style arrangement connected together by means of a connector pin 155 such that modules of shuttle display sign devices of the present invention may be coupled together in end to end rela­tionship whereby draw bars of adjacent modules may be driven by a single reversible step motor 151 to thereby minimize the expense of the drive system and positively assure synchroniza­tion between all modules driven by a common drive.
  • pairs of the display panels 47 - 67 which are simultaneously displayed to one side of the base 23 will typically incorporate segments of a common visual display such that the panels together exhibit of modular bases 23 necessary for displaying the entire composite display may be coupled together such that the dis­play panels mounted therein will cooperate to form the overall length of composite display area necessary for the message to be displayed.
  • the step motor 151 is rotated to its next control posi­tion to shift the draw bars to their unloading position shown in FIG. 12 with the notches 141 and 143 registered with the front ends of the lateral tracks 27 and 29 as shown in FIG. 12. Simultaneously, the notches 142 and 144 of the rearward rack 133 will be registered with the lefthand lateral tracks 23 and 25.
  • the bell crank solenoid motor 105 is then again actuated momentarily to enable the spring 107 to rotate the bell crank 110 counterclockwise as viewed in FIGS. 6 and 8 to again shift the lefthand drive tray forwardly in the base 21 and the righthand drive tray 104 rearwardly in such base thereby causing the pusher bars 112 and 114 to push the fol­lowers 89 of the forwardly and rearwardly respective panels 59 and 57 from the respective shuttle tracks 31 and 33 and into the respective pairs of tracks 23 - 25 and 27 - 29 to unload the rollers.
  • step motor 151 is then reversed to its next control position thus rotating the ring gear 131 clockwise to drive the draw bar 135 to the left as viewed in FIG. 13 to its loading position and the rear draw bar 133 to the right a distance sufficient to cause the notches 141 and 143 of the front draw bar 135 to register with the lateral tracks 23 and 25 and the notches 142 and 144 of the rear draw bar 133 to register with the tracks 27 and 29.
  • the bell crank 110 is then again operated to advance the next pair of rollers 89 from the tracks 23 and 25 corresponding with the panel 55 into the notches 141 and 143 of the draw bar 135 and to retract the tray 104 to cause the pusher bar 114 to drive the followers 89 of the tracks 27 and 29 rearwardly to engage the rearmost pair of followers 89 corresponding with the panel 61 with the notches 142 and 149.
  • the step motor 151 is operated to rotate the ring gear 131 counterclockwise to translate the rollers 89 for the display panel 55 to the right as viewed in FIGS. 1 and 12 to the loading position aligned with the tracks 27 and 29.
  • the bell crank 110 acting through the escort trays 102 and 104 is operated to retract the rows of followers 89 in the pair of tracks 27 and 29 and to advance the followers 89 in the tracks 23 and 25 then pushing the rollers of the panels 35 and 61 from the shuttle track into such respective pairs of lateral tracks.
  • the step motor 151 is then reversed to drive the draw bars 133 and 135 to their locked positions shown in FIG. 6 to thus engage the respective locking abut­ments 160, 162, 164 and 166 formed at the interior ends of the ramps defining one side of the respective notches 141 - 142 to thus lock the rollers 89 and, consequently, the panels 47 - 69 positively in position.
  • the draw bars are then held in this locked position for a predetermined period of time, as for instance 60 seconds, with the message segments on the backside of the panels 61 and 63 and the display segments on the front sides of the panels 53 and 55 are disposed as a composite mes­sage.
  • the parallel tracks 23, 25 and 27 - 29 serve to hold the panels 47 - 69 parallel to one another for compact storage and viewing in abreast pairs.
  • other well known mechanisms such as slot, slider and cam arrangements might be employed to serve this function.
  • the panel 53 has now been moved to the front of the lefthand rack and the panel 55 to the front of the righthand rack (FIG. 1).
  • the display panels 61 and 63 are disposed abreast of one another in coplanar rela­tionship at the back of the base 21.
  • FIGS. 14a - 14g The steps set forth above are depicted diagrammatic strictlyally in FIGS. 14a - 14g for only four display panels.
  • the common side of the display panel facing rearwardly is repre­sented by the numeral 1 for the pair of panels disposed in side by side relationship and the front side of the first pair of such panels is represented by the numeral 4.
  • the front side of the second pair of panels is depicted by the numeral 2 and the rear side thereof depicted by the numeral 3.
  • FIG. 14b The first operation of advancing the left hand panels for­wardly in the lefthand pair of tracks and retracting the righthand tracks of panels rearwardly in the righthand tracks is depicted in FIG. 14b.
  • FIG. 14c represents lateral shuttl­ing of the foremost and rearmost panels.
  • FIG. 14d represents advancement of the lefthand rack of panels and retracks into the righthand rack of panels.
  • FIG. 14e represents retraction of the righthand rack of panels to dispose the rearmost panel in the shuttle track and advancement of the lefthand rack of panels to dispose the foremost panel in the forward shuttle track.
  • FIG. 14f depicts shuttling of the foremost and rear­most panel.
  • Fig. 14g depicts the new display faces 33 and 44 disposed in coplanar relationship facing rearwardly and for­wardly of the display device.
  • the entire sequence may be initiated again to advance the front faces of the pair of panels 49 and 51 for viewing from the front and retracting the pair 65 and 67 for viewing from the rear. This process will then be repeated until all the different message have been displayed and, if desired, the entire cycle then re­initiated. It will be recognized by those skilled in the art that any commercially available controls may be employed to control this operation and that a computerized program is most adaptable to the system.
  • the shuttle display apparatus of the present invention provides an economical and convenient means for displaying a nearly un­limited number of composite messages both in the forwardly and rearward directions.
  • the length of display time may conven­iently be programmed into the system and the display panels easily changed for the purposes of changing the messages dis­played thereon.
