The display panel has a plurality of columns of a square cross sectional configuration wherein alternating columns are reciprocally displaced and then rotated about their longitudinal axis to bring a new display face for presentation.
Description
4 ~
The present invention relates to a display device and more particularly, relates to a display device having a plurality of square members or columns which can be rotated.
Display devices or signs which can display more than one face are known in the art. Originally, such devices comprised a plurality of display members which could be rotated through 180 so that two different signs could be displayed for short intervals of time. Such devices were somewhat elementary and lacked the ability to, for example, be illuminated to provide desired effects.
An improvement on the double sided display system was achieved with use of triangular shaped members which are mounted for rotation about their longitudinal axis with the members being juxtaposed. A drive system is utilized to successively display the three different faces.
Thus, when it is desired to change a sign, each member is rotated through 120.
It is obviously desirable to provide as many different display faces in a sign as possible. At the same time, such a sign must provide for ease of maintenance and changing of the displayed image.
It is an object of the present invention to provide a display panel wherein four different displays may be mounted on a single sign.
It is a further object of the present invention to provide a display panel having means for displaying four different potential images and means for moving the members ~15~748 to display such images.
According to one aspect of the present invention, there is provided a display device comprising a plurality of elongated display columns with each column having a substantially square cross sectional configuration to thereby provide four display faces. The columns are arranged in a row such that the display faces of each column will form a desired display. The device includes means for reciprocally displacing alternating columns from the row and for rotating the columns while the columns are in a displaced condition.
After rotation, the columns are moved back into a row with a new image being displayed.
In greater detail, the present invention provides a display device or structure wherein there are provided a plurality of elongated display columns with each column extending longitudinally and having a substantially square cross sectional configuration to thereby provide for display faces. The columns are aligned in a row such that adjacent display faces will form a desired display image. There are provided means for reciprocally displacing alternating columns and also means for rotating the columns while the columns are in a displaced position to thereby present a new mage .
The present invention provides a display device which is capable of displaying four different images. Each image is formed by a plurality of display faces of the columns which are arranged in a row. When it is desired to - 21S~7'~
change the display image being presented, alternating columns are displaced and then all the columns are rotated about their longitudinal axis to thereby present a different display face. The displaced columns are then moved back into the desired position which then presents a new display image.
Preferably, the columns have an interior light source with a transparent/translucent display face to thereby present a very attractive display image.
The present invention presents the advantage of a system which is relatively maintenance free while permitting ready access for both changing the images, the illuminating source and/or a particular column.
Having thus generally described the invention, reference will be made to the accompanying drawings illustrating an embodiment thereof, in which:
Figure 1 is a perspective view of an illuminated display unit according to the present invention.
Figure la is a view similar to Figure 1 showing the illuminated display unit in a vertical orientation;

Referring to the drawings in greater detail and by reference characters thereto, there is illustrated in Figures 1 and la display units 10 and 10', the units being substantially identical except for their horizontal and vertical orientation respectively. The display units 10 and 10' have opposed side walls 12 and 14 and opposed end walls 2~ 16 and 18. There is also provided a front wall 20 and a rear wall 22. End wall 16 may conveniently be provided with an electrical outlet as designated by reference numeral 24.
Each display unit includes a plurality of individual display members generally designated by reference numeral 26 and which as shown in Figures 1 and la, are adapted to display information thereon in a known manner.
Picture display member 26, as may be seen in Figure 2, is - - 215~7 i~
mounted rearwardly of a transparent element 32 which is retained in position by means of retaining elements 34 which in turn are secured to inwardly directed flanges 28 and 30 extending inwardly from front wall 20.
Each display member 26 has four different faces - a first face 36, a second face 38, a third face 40 and a fourth face 42 as may be seen in Figure 5a. Each face is adapted to carry a different message and thus, the potential for sequential or otherwise displaying four different messages can be achieved. Each face element is adapted to fit between an upper member 44 and a lower member 46 and each can be replaced when it is desired to replace the message being portrayed. Alternatively, as previously mentioned, one may use images which are glued either temporary or permanent to each face element. Such transparencies are known in the art.
Mounted interiorly of the face elements 36, 38, 40 and 42 is a light emitting member 48 which conveniently may be of the so called neon type.
Reference will now be made to Figure 6 which illustrates in greater detail the structure of each display member 26. Thus, as may be seen in Figure 6, light emitting element 48 is operatively connected by means of wires 50 to a suitable power source (not shown). Wires 50 are mounted within an interior shaft 52 which is secured to the base of light emitting element 48 and does not rotate as will be discussed in greater detail hereinbelow. Bottom member 46, besides acting as a seat for each of the faces of display - 21~07~
member 26, has a cylindrical portion 54 mounted adjacent to and exteriorly of shaft 52.
A base member 56 is secured by means of a screw 58 to an upwardly extending frame member 70 and a rack gear 60.
A lower base member 64 has a wheel 66 journalled about a shaft 68' wheel 66 is adapted to ride on the interior of wall 14. Within base member 56 there is provided an aperture adapted to receive a biasing pin 72 which fits within one of four detents 74 formed on an exterior wall of the cylindrical portion of member 54. The biased pin will thus secure the display member 26 in the desired position upon movement thereof as will be discussed hereinbelow. A gear wheel 62 is suitably secured to member 54 so that upon rotatable movement of gear 62, both member 54 and display member 26 will rotate.
Referring back to Figures 2 and 2a, it will be seen that upper member 44 has a cylindrical extension 78 adapted to fit within an aperture in upper frame member 76 to permit rotatable movement of display member 26.
As may be seen in Figures 1, 4 and 5, when the display members 26 are in a position for displaying a message, the front faces form a substantially continuous plane. When it is desired to turn the display elements 26 to display a further message, it is necessary to reorient the display members in order to permit rotational movement.
Thus, as shown in Figures 2a and 5a, the rotational movement is effected when every second display member is displaced horizontally to permit rotational movement. This horizontal 21507~8 displacement is achieved by means of an electrical motor 90 suitably mounted to wall 16 and which, as may be seen from Figure 3, is adapted to drive a drive shaft 92 about which is entrained a first chain drive 94 and a second chain drive 96.
An upper shaft 98 extends between walls 16 and 18 and is rotatably driven by chain drive 94. Similarly, a lower shaft 100 has second chain drive 96 entrained thereabout for rotatably driving the same. As may be seen in Figure 5 and 5a, operation of electric motor 90 will, through chain drive 94, cause rotation of shaft 98. Mounted on shaft 98 are a plurality of pinion gears 102 which act to engage rack gears 80. Similarly, at the bottom of the display unit, lower shaft 100 has mounted thereon a plurality of pinion gears 104 to engage rack gears 60. Thus, when motor 90 is operated, shafts 98 and 100 are rotatably driven through chain drives 94 and 96 respectively which in turn will cause horizontal displacement of each second or alternating display member 26.
The arrangement includes a second electrical motor 106 to rotatably drive a shaft 108 about which is entrained a chain drive 110. Chain drive 110 has a somewhat rectangular configuration as it passes around chain guides 112. Chain 110 is also entrained about gear 62 at the bottom of each display member 26. As shown in Figure 5a, horizontal displacement of each alternating member 26 through operation of motor 90 will act such that when moved horizontally or rearwardly those elements which have moved will engage the return portion of chain drive 110. Operation of motor 106 - 2~ ~07 18 will thus act to cause rotatable movement of all display elements 26 as may be seen in Figure 5a.
The arrangement may conveniently include, as shown in Figures 4, 4a and 8, tensioning devices 114 for chain drive 110. Such tensioning devices are well known in the art and are adapted to maintain the required tension on the chain.
It will be understood that the above described embodiment is for purposes of illustration only and that changes and modifications may be made thereto without departing from the spirit and scope of the invention.

Figure 6 is a detailed view of that portion indicated by arrow 6 in Figure 2;
Figure 7 is a sectional view taken along the lines 7-7 of Figure 6; and Figure 8 illustrates the chain drive system.
Referring to the drawings in greater detail and by reference characters thereto, there is illustrated in Figures 1 and la display units 10 and 10', the units being substantially identical except for their horizontal and vertical orientation respectively. The display units 10 and 10' have opposed side walls 12 and 14 and opposed end walls 2~ 16 and 18. There is also provided a front wall 20 and a rear wall 22. End wall 16 may conveniently be provided with an electrical outlet as designated by reference numeral 24.
Each display unit includes a plurality of individual display members generally designated by reference numeral 26 and which as shown in Figures 1 and la, are adapted to display information thereon in a known manner.
Picture display member 26, as may be seen in Figure 2, is - - 215~7 i~
mounted rearwardly of a transparent element 32 which is retained in position by means of retaining elements 34 which in turn are secured to inwardly directed flanges 28 and 30 extending inwardly from front wall 20.
Each display member 26 has four different faces - a first face 36, a second face 38, a third face 40 and a fourth face 42 as may be seen in Figure 5a. Each face is adapted to carry a different message and thus, the potential for sequential or otherwise displaying four different messages can be achieved. Each face element is adapted to fit between an upper member 44 and a lower member 46 and each can be replaced when it is desired to replace the message being portrayed. Alternatively, as previously mentioned, one may use images which are glued either temporary or permanent to each face element. Such transparencies are known in the art.
Mounted interiorly of the face elements 36, 38, 40 and 42 is a light emitting member 48 which conveniently may be of the so called neon type.
Reference will now be made to Figure 6 which illustrates in greater detail the structure of each display member 26. Thus, as may be seen in Figure 6, light emitting element 48 is operatively connected by means of wires 50 to a suitable power source (not shown). Wires 50 are mounted within an interior shaft 52 which is secured to the base of light emitting element 48 and does not rotate as will be discussed in greater detail hereinbelow. Bottom member 46, besides acting as a seat for each of the faces of display - 21~07~
member 26, has a cylindrical portion 54 mounted adjacent to and exteriorly of shaft 52.
A base member 56 is secured by means of a screw 58 to an upwardly extending frame member 70 and a rack gear 60.
A lower base member 64 has a wheel 66 journalled about a shaft 68' wheel 66 is adapted to ride on the interior of wall 14. Within base member 56 there is provided an aperture adapted to receive a biasing pin 72 which fits within one of four detents 74 formed on an exterior wall of the cylindrical portion of member 54. The biased pin will thus secure the display member 26 in the desired position upon movement thereof as will be discussed hereinbelow. A gear wheel 62 is suitably secured to member 54 so that upon rotatable movement of gear 62, both member 54 and display member 26 will rotate.
Referring back to Figures 2 and 2a, it will be seen that upper member 44 has a cylindrical extension 78 adapted to fit within an aperture in upper frame member 76 to permit rotatable movement of display member 26.
As may be seen in Figures 1, 4 and 5, when the display members 26 are in a position for displaying a message, the front faces form a substantially continuous plane. When it is desired to turn the display elements 26 to display a further message, it is necessary to reorient the display members in order to permit rotational movement.
Thus, as shown in Figures 2a and 5a, the rotational movement is effected when every second display member is displaced horizontally to permit rotational movement. This horizontal 21507~8 displacement is achieved by means of an electrical motor 90 suitably mounted to wall 16 and which, as may be seen from Figure 3, is adapted to drive a drive shaft 92 about which is entrained a first chain drive 94 and a second chain drive 96.
An upper shaft 98 extends between walls 16 and 18 and is rotatably driven by chain drive 94. Similarly, a lower shaft 100 has second chain drive 96 entrained thereabout for rotatably driving the same. As may be seen in Figure 5 and 5a, operation of electric motor 90 will, through chain drive 94, cause rotation of shaft 98. Mounted on shaft 98 are a plurality of pinion gears 102 which act to engage rack gears 80. Similarly, at the bottom of the display unit, lower shaft 100 has mounted thereon a plurality of pinion gears 104 to engage rack gears 60. Thus, when motor 90 is operated, shafts 98 and 100 are rotatably driven through chain drives 94 and 96 respectively which in turn will cause horizontal displacement of each second or alternating display member 26.
The arrangement includes a second electrical motor 106 to rotatably drive a shaft 108 about which is entrained a chain drive 110. Chain drive 110 has a somewhat rectangular configuration as it passes around chain guides 112. Chain 110 is also entrained about gear 62 at the bottom of each display member 26. As shown in Figure 5a, horizontal displacement of each alternating member 26 through operation of motor 90 will act such that when moved horizontally or rearwardly those elements which have moved will engage the return portion of chain drive 110. Operation of motor 106 - 2~ ~07 18 will thus act to cause rotatable movement of all display elements 26 as may be seen in Figure 5a.
The arrangement may conveniently include, as shown in Figures 4, 4a and 8, tensioning devices 114 for chain drive 110. Such tensioning devices are well known in the art and are adapted to maintain the required tension on the chain.
It will be understood that the above described embodiment is for purposes of illustration only and that changes and modifications may be made thereto without departing from the spirit and scope of the invention.
