- ABSTRACT A display sign which has a plurality otgidless strings of planar elements. An element of one string cooperates with corresponding elements of the strings to form an advertising or other display panel when such elements are placed side by side in a common frontal plane.
- the strings of elements are supported by vertically disposed shafts which are synchronously rotated to bring the elements into proper alignment.
- the invention comprises a display sign which employs a plurality of endless strings of planer elements to successively present, with precision, numerous advertising images on the same panel for a brief period of time while restricting the view between adjacent strings during movement thereof.
- the panels are formed upon an element of one string being synchronously brought into view with corresponding elements of the other strings.
- the principal object of this invention is to provide a display sign which successively presents'numerous different advertising images in an attractive fashion.
- FIG. 4 is a sectional view taken along 4-4 of FIG.
- FIG. 5 is a sectional view taken along line 5-5 of FIG. 4, showing the drive motor.
- FIG. 6 isa sectional view taken along line 6-6 of FIG. 3.
- FIG. 7 is a sectional view taken along line 77 of FIG. 3.
- FIG. 8 is a sectional view taken along line 8-8 of FIG. 7.
- FIG. 9 is a partial perspective view of a mounting panel.
- the display sign 10 is seen in FIGS. 1 through 3 to be comprised of a plurality of juxtaposed endless strings 12 of planar elements 14 mounted on a frame 16.
- Each string is formed by an upper and lower band 18 and 20 which are secured to the planar elements 14 by rivets or other suitable fastening means 22.
- Each planar element has an upper flange portion 24 and curled edges 26 at the sides thereof.
- Elongated panels 28 having rounded holding flanges 29 integrally formed along the sides thereof [See FIG. 9] are positioned over the planar elements 14 with the holding flanges 29 pressing against the curled edges 26 of the planar elements.
- the images displayed by the sign 10 are carried on these panels 28.
- means are provided to drive the endless strings 12 into rotation and that a panel 28 carried by an element 14 is adapted to cooperate with a corresponding panel and element of each of the other strings to form a given display when placed side by side in a common frontal plane, as shown in FIG. I.
- the endless strings of panel carrying planar elements are supported by pairs of vertical shafts.
- Each string is carried by a forward driving shaft 30 and a rearward support shaft 32 by means of triangularly shaped indexing members 34.
- Each shaft is rotatably mounted upon the frame 16 by means of bushings 36, with all the driving shafts being in a single frontal plane and the rearwardly disposed support shafts also being linearly aligned.
- the idexing members 34 are preferably constructed of a non-metallic material, such as nylon or plastic, and are secured to the shafts by means of triangularly shaped metallic plates 38 which are seated within correspondingly shaped hollow interiors 40 of the indexing members. The plates are then welded to the shafts as shown in FIGS. 7 and 8.
- indexing members In each endless string, four indexing members are employed, an upper and lower member being secured to each shaft, corresponding with the upper and lower bands 18 and 20 which form the strings. It should be noted that all the indexing members are similarly oriented, thereby presenting a flat forward surface and pointed rear. This orientation prevents undue amounts of slack from developing in the strings upon rotating movement thereof.
- Each indexing member has a recessed area 42 on each of the three sides thereof and teeth-like members 43 at the three corners. The recessed area is adapted to receive holding flanges 29 of the elongated panels and the curled edges 26 of the planar elements, while the tooth portion extends between the adjacent planar elements during the movement thereof, to aid in indexig and moving the successive elements into proper frontal alignment.
- each of the rearward support shafts 32 is disposed a slight distance outwardly from the center of the display sign along the frame 16 with respect to the driving shafts. This provides a small spacing between the rearward indexing members to prevent contact between adjacent members during rotation thereof. This spacing is not necessary between those members mounted on the driving shafts due to the more precise movement thereof as contrasted with that of the indirectly driven support shafts.
- the synchronizing and driving mechanisms of the display sign can be understood with particular reference to FIGS. 2, 4 and 5. It can be seen in FIG. 2 that the rearward support shafts are rotatably mounted at both ends thereof on the frame 16, while the lower ends of the drive shafts have cranks 44 extending therefrom.
- the cranks may be integrally formed with the driving shafts or otherwise affixed to the lower ends thereof.
- the upper ends of the driving shafts are rotatably mounted in the frame by means of bushings 36, while the lower ends of the crank are similarly rotatably mounted along a synchronizing bar 46 by means of bushings 48.
- the synchronizing bar thus interconnects all of the driving shafts 30 and it can be seen that by imparting rotation to at least two of the shafts and preferably to the two end shafts, the remaining drive shafts are caused to undergo the same degree of angular rotation.
- the use of the two end shafts provides a higher figure of accurate rotation than would otherwise be obtained through the use of any other pair of shafts.
- a gear motor 50 is mounted on a support plate 51 which is carried by lower horizontal support brackets.
- a geneva drive assembly 54 is secured to the drive shaft 56 of the motor.
- the geneva drive consists of a drive wheel 58 having a cam 60 thereon which is adapted to travel within slots 62 in the driven wheel 64, thereby imparting periodic 90 rotation to the driven wheel rotating on a stationary shaft 66 while holding said driven wheel motionless during the interim by means of the curved cam surface 68 on the driving wheel 58 moving against one of the four curved surfaces 70 on the driven wheel 64.
- a drive sprocket 72 is secured to the driven wheel 64 by fastening means 67.
- a pair of driven sprockets 74 are secured to the two driving shafts 30 disposed at the opposite ends of display sign 10, as seen in FIG. 4.
- An endless sprocket chain 75 extends about the three sprockets for imparting rotary movement to the driving shafts 30 from the movement of the geneva drive assembly 54.
- the support plate 51 has slots 65 therein whereby the geneva drive assembly and drive sprocket can be adjusted to attain the proper tension in the sprocket chain 75.
- Clamps 76 are used to secure the two driven sprockets to the driving shafts to allow for proper adjustment of the sprockets on the driving shafts and to maintain the proper orientation of the planar elements 14 and panels 28 carried thereby subsequent to initial adjustment.
- the slide bars are caused to undergo reciprocal movement with respect to the frame 16 by the force of the endless strings pressing against the spacer wheels 78.
- the rollers and slide bar prevent corners of the panels 28 from interfering with each other during the movement of the strings and further, prevent rubbing between panel surfaces and scratching the portion of the display painted or otherwise secured thereon.
- the wheels are rotatably mounted on the slide bars to reduce any drag which otherwise might be caused by the bands 18 and 20 pressing against the wheels. This forced reciprocal movement of the slide bars, continually takes up any slack and maintains each of the endless strings of planer elements in a taut disposition.
- rollers 88 are secured to the bottom of frame 16.
- a wooden or other suitable outer covering 90 is placed aboutthe frame and a glass pane 91 is placed across the front of the sign to present a more attractive appearance.
- the driving shafts 30 can be extended upwardly through the outer covering as seen in FIGS. 1 and 2.
- Triangularly shaped display members 92 are secured to the upper extensions of the driving shafts. One face of each display member cooperates with a face of the other display members to present a given word or message. As the driving shafts are periodically rotated, three different messages successively appear atop the display sign.

8 Claims, 9 Drawing Figures :Z 1 l l! 90 PATENTEB JULS 0 I974 SHEET t 0F 4 1 MULTI-FACED DISPLAY SIGN BACKGROUND OF THE INVENTION The problem of limited outdoor advertising space is presently being met by billboards which synchronously rotate a series of tri-surface elements to periodically display three different advertising panels. Such devices are expensive and their use has generally been limited to prime outdoor locations where they are constantly visible to the public. The tri-faced sign, however, has made few inroads on the indoor advertising market, as the costs involved therein are generally felt to overshadow the benefit obtained from two advertising panels. Some signs have been developed, however, which are capable of displaying several different advertising panels. An example of this type of sign is found in US. Pat. No. 3,229,395. The device shown therein, as is the case with other similar display signs, has failed to satisfy the need in the indoor advertising market. Such signs are expensive and while the expense may well be justifled by the versatility of the signs, their appearance is a major shortcoming. In operation, these multi-faced display signs allow the customer to periodically view the interior mechanism of the sign which is distracting, detracts from the message being carried thereby and is generally unattractive. The appearance factor has been a major influence in preventing the acceptability of multi-faced signs in indoor advertising.
SUMMARY OF THE INVENTION Briefly, the invention comprises a display sign which employs a plurality of endless strings of planer elements to successively present, with precision, numerous advertising images on the same panel for a brief period of time while restricting the view between adjacent strings during movement thereof. The panels are formed upon an element of one string being synchronously brought into view with corresponding elements of the other strings.
The principal object of this invention is to provide a display sign which successively presents'numerous different advertising images in an attractive fashion.
It is another object of this invention to provide a display sign which precisely indexes the corresponding elements to present successive images.
It is a further object of this invention to provide a display sign which successively presents numerous different advertising images for a briefperiod of time which is attractive and likely to attract the attention of passersby.
It is yet another object of this invention to provide a display sign which successively presents numerous different advertising images which is of simple construction and relatively economically to manufacture.
These and other objects and advantages of the instant invention will be apparently on the following detailed description taken in conjunction with the accompanying drawings.

FIG. 9 is a partial perspective view of a mounting panel.
Referring now in detail to the drawings, the display sign 10 is seen in FIGS. 1 through 3 to be comprised of a plurality of juxtaposed endless strings 12 of planar elements 14 mounted on a frame 16. Each string is formed by an upper and lower band 18 and 20 which are secured to the planar elements 14 by rivets or other suitable fastening means 22. Each planar element has an upper flange portion 24 and curled edges 26 at the sides thereof. Elongated panels 28 having rounded holding flanges 29 integrally formed along the sides thereof [See FIG. 9] are positioned over the planar elements 14 with the holding flanges 29 pressing against the curled edges 26 of the planar elements. The images displayed by the sign 10 are carried on these panels 28. As will be described, means are provided to drive the endless strings 12 into rotation and that a panel 28 carried by an element 14 is adapted to cooperate with a corresponding panel and element of each of the other strings to form a given display when placed side by side in a common frontal plane, as shown in FIG. I.
The endless strings of panel carrying planar elements are supported by pairs of vertical shafts. Each string is carried by a forward driving shaft 30 and a rearward support shaft 32 by means of triangularly shaped indexing members 34. Each shaft is rotatably mounted upon the frame 16 by means of bushings 36, with all the driving shafts being in a single frontal plane and the rearwardly disposed support shafts also being linearly aligned. The idexing members 34 are preferably constructed of a non-metallic material, such as nylon or plastic, and are secured to the shafts by means of triangularly shaped metallic plates 38 which are seated within correspondingly shaped hollow interiors 40 of the indexing members. The plates are then welded to the shafts as shown in FIGS. 7 and 8. In each endless string, four indexing members are employed, an upper and lower member being secured to each shaft, corresponding with the upper and lower bands 18 and 20 which form the strings. It should be noted that all the indexing members are similarly oriented, thereby presenting a flat forward surface and pointed rear. This orientation prevents undue amounts of slack from developing in the strings upon rotating movement thereof. Each indexing member has a recessed area 42 on each of the three sides thereof and teeth-like members 43 at the three corners. The recessed area is adapted to receive holding flanges 29 of the elongated panels and the curled edges 26 of the planar elements, while the tooth portion extends between the adjacent planar elements during the movement thereof, to aid in indexig and moving the successive elements into proper frontal alignment. The upper flange portion 24 of the planar element is then disposed atop the indexing member as shown in FIG. 3. It can be seen that rotation of the forward driving shafts 30 cause corresponding movement of the endless strings carried thereby and rotation of the rearward support shafts 32, with the holding flanges on the panels cooperating with the recessed areas 42 on the indexing members and the tooth portions extending between the elements 14 in gear meshing relationships whereby exacting periodic rotation of the driving shafts causes precise orientation of successive planar elements 14 and elongated panels 28. It should also be noted that each of the rearward support shafts 32 is disposed a slight distance outwardly from the center of the display sign along the frame 16 with respect to the driving shafts. This provides a small spacing between the rearward indexing members to prevent contact between adjacent members during rotation thereof. This spacing is not necessary between those members mounted on the driving shafts due to the more precise movement thereof as contrasted with that of the indirectly driven support shafts.
The synchronizing and driving mechanisms of the display sign can be understood with particular reference to FIGS. 2, 4 and 5. It can be seen in FIG. 2 that the rearward support shafts are rotatably mounted at both ends thereof on the frame 16, while the lower ends of the drive shafts have cranks 44 extending therefrom. The cranks may be integrally formed with the driving shafts or otherwise affixed to the lower ends thereof. The upper ends of the driving shafts are rotatably mounted in the frame by means of bushings 36, while the lower ends of the crank are similarly rotatably mounted along a synchronizing bar 46 by means of bushings 48. The synchronizing bar thus interconnects all of the driving shafts 30 and it can be seen that by imparting rotation to at least two of the shafts and preferably to the two end shafts, the remaining drive shafts are caused to undergo the same degree of angular rotation. The use of the two end shafts provides a higher figure of accurate rotation than would otherwise be obtained through the use of any other pair of shafts.
A gear motor 50 is mounted on a support plate 51 which is carried by lower horizontal support brackets. A geneva drive assembly 54 is secured to the drive shaft 56 of the motor. The geneva drive consists of a drive wheel 58 having a cam 60 thereon which is adapted to travel within slots 62 in the driven wheel 64, thereby imparting periodic 90 rotation to the driven wheel rotating on a stationary shaft 66 while holding said driven wheel motionless during the interim by means of the curved cam surface 68 on the driving wheel 58 moving against one of the four curved surfaces 70 on the driven wheel 64. A drive sprocket 72 is secured to the driven wheel 64 by fastening means 67. A pair of driven sprockets 74 are secured to the two driving shafts 30 disposed at the opposite ends of display sign 10, as seen in FIG. 4. An endless sprocket chain 75 extends about the three sprockets for imparting rotary movement to the driving shafts 30 from the movement of the geneva drive assembly 54. The support plate 51 has slots 65 therein whereby the geneva drive assembly and drive sprocket can be adjusted to attain the proper tension in the sprocket chain 75. Clamps 76 are used to secure the two driven sprockets to the driving shafts to allow for proper adjustment of the sprockets on the driving shafts and to maintain the proper orientation of the planar elements 14 and panels 28 carried thereby subsequent to initial adjustment. To attain the-desired 120 rotation of the driving shafts 30 from the periodic rotation of the geneva drive assembly, a tooth ratio of 4:3
is used between the drive sprocket 72 and the driven sprockets 74. It can be seen that the exacting periodic rotation of the driven wheel 64 is thus translated through the sprockets to exacting periodic rotation of the driving shafts30 and panels 28 carried thereby. In this manner, and in conjunction with the meshing relationship between the triangular indexing members and endless strings of planar elements, advertising or other display panels are successively and exactingly shown for a brief period of time across the front of the display sign.
While the corresponding alignment of the front and rear trinagular indexing members 34 greatly reduces the amount of slack in the endless string 12 during movement thereof, some slack, nevertheless, occurs. This slack is taken up by a plurality of spacing wheels 78 which are rotatably mounted on upper and lower slide bars 80. These bars are slidably mounted on frame 16 by bracket 82. The brackets are constructed of nonmetallic material, such as nylon, and have a pair of vertical flange portions 84 which, in the upstanding position [e.g., lower slide bar mounting], relieve the pressure from the lower ends of the flange portions 86 of the bar [See FIG. 2]. As the endless strings rotate, the slide bars are caused to undergo reciprocal movement with respect to the frame 16 by the force of the endless strings pressing against the spacer wheels 78. In addition to maintaining the strings of planar elements in a taut disposition, the rollers and slide bar prevent corners of the panels 28 from interfering with each other during the movement of the strings and further, prevent rubbing between panel surfaces and scratching the portion of the display painted or otherwise secured thereon. The wheels are rotatably mounted on the slide bars to reduce any drag which otherwise might be caused by the bands 18 and 20 pressing against the wheels. This forced reciprocal movement of the slide bars, continually takes up any slack and maintains each of the endless strings of planer elements in a taut disposition.
Finally, rollers 88 are secured to the bottom of frame 16. A wooden or other suitable outer covering 90 is placed aboutthe frame and a glass pane 91 is placed across the front of the sign to present a more attractive appearance. In addition, the driving shafts 30 can be extended upwardly through the outer covering as seen in FIGS. 1 and 2. Triangularly shaped display members 92 are secured to the upper extensions of the driving shafts. One face of each display member cooperates with a face of the other display members to present a given word or message. As the driving shafts are periodically rotated, three different messages successively appear atop the display sign.
Various changes and modifications may be made in carrying out the present invention without departing from the spirit and scope thereof. Insofar as these changes and modifications are within the purview of the appended claims they are to be considered as part of the invention.
