Apparatus for programmed display of advertising matter such as placards, posters or the like

Claim 1

An apparatus for the programmed display of advertising matter such as placards, posters and the like comprising a plurality of units (7) arranged in a stand (2) in spaced apart relationship and each having a plurality of frames (9a-9f) which are disposed to pivot about a common axis (8) and each have two opposite sides (10,11), one side (10) of a frame (9a) turned towards a viewer cooperating with the other side (11) of a second frame (9b) turned towards the viewer to form part of a display surface (17) for a poster and the remainder of the display surface being formed by corresponding cooperating sides (10, 11) of the frames (9a, 9b) of the other units (7) which are turned towards the viewer, and an operating mechanism (19) for simultaneously turning at fixed intervals one of the frames (9a) of each unit (7) which are turned towards the viewer through substantially 180° to cause said frame to take the position of the other frame (9b) turned towards the viewer, said last-mentioned frame being caused by the action of the frame turning through substantially 180° to turn through a determined angle (a) about the common axis and to turn the leading frames (9c-9f) as seen in the direction of turning through an equally large angle, whereby the foremost frame (9f) as viewed in the direction of turning is caused to take the earlier position of the frame (9a) turning through substantially 180° and to have its side (10) facing the viewer cooperate with the other side (11) of the frame swung through substantially 180° to form part of another display surface (17) for another poster and so on so that all posters are sequentially displayed a repeated number of times, wherein the operating mechanism (19) comprises a drive assembly (21) and a linkage (22) driven by said assembly and connected to said units (7), wherein the linkage (22) comprises a link (27) pivoted at one end (28) to said disk (26) and being pivoted at its other end (30) to a pivot arm (32) between the ends (33,34) thereof, said pivot arm being pivoted with its one end (33) in said stand (2) above the unit (7) closest to the drive assembly (21) to actuate the frames (9a-9f) of said unit and being pivoted between the joint connection (29) for said link (27) and its free end (34) to a connecting rod (37) which is hinged to further pivot arms (46-49) pivotally mounted in the stand (2) and each associated with the other units (7), said further pivot arms being pivotal in synchronism with said first pivot arm (32) for simultaneous actuation of the frames (9a-9f) of all units, the pivot arms (32, 46-49) carrying at their free ends (34) a lever (53) which can be swung against the action of a spring (56) connected to a lug (57) on said pivot arm (32) and to said lever (53) through a pin (52) extending through said free end (34) and which supports at its free end a freely rotatable roller (54) which when the pivot arms (32, 46-49) are swung in one direction first rolls on the outwardly facing side (58) of the frame (9b) last turned through substantially 180°, then on the outwardly facing side (59) of the frame (9a) which is to be turned next through substantially 180°, and finally past the free long edge (60) of said frame to be transferred by the action of the spring (56) actuating the lever onto the rearwardly facing said (61) of the frame, and when the pivot arms (32, 46-49) are swung in the other direction rolls on the rearwardly facing side (61) and turns the frame (9a) through substantially 180° so that the rearwardly facing side will be facing outwardly, whereupon the procedure is repeated.

Claim 2

An apparatus for the programmed display of advertising matter such as placards, posters and the like comprising a plurality of units (7) arranged in a stand (2) in spaced apart relationship and each having a plurality of frames (9a-9f) which are disposed to pivot about a common axis (8) and each have two opposite sides (10,11), one side (10) of a frame (9a) turned towards a viewer cooperating with the other side (11) of a second frame (9b) turned towards the viewer to form part of a display surface (17) for a poster and the remainder of the display surface being formed by corresponding cooperating sides (10, 11) of the frames (9a, 9b) of the other units (7) which are turned towards the viewer, and an operating mechanism (19) for simultaneously turning at fixed intervals one of the frames (9a) of each unit (7) which are turned towards the viewer through substantially 180° to cause said frame to take the position of the other frame (9b) turned towards the viewer, said last-mentioned frame being caused by the action of the frame turning through substantially 180° to turn through a determined angle (a) about the common axis and to turn the leading frames (9c-9f) as seen in the direction of turning through an equally large angle, whereby the foremost frame (9f) as viewed in the direction of turning is caused to take the earlier position of the frame (9a) turning through substantially 180° and to have its side (10) facing the viewer cooperate with the other side (11) of the frame swung through substantially 180° to form part of another display surface (17) for another poster and so on so that all posters are sequentially displayed a repeated number of times, wherein the operating mechanism (19) comprises a drive assembly (21) and a linkage (22) driven by said assembly and connected to said units (7), wherein the linkage (22) comprises a link (27) pivoted at one end (28) to said disk (26) and being pivoted at its other end (30) to a pivot arm (32) between the ends (33,34) thereof, said pivot arm being pivoted with its one end (33) in said stand (2) above the unit (7) closest to the drive assembly (21) to actuate the frames (9a-9f) of said unit and being pivoted between the joint connection (29) for said link (27) and its free end (34) to a connecting rod (37) which is hinged to further pivot arms (46-49) pivotally mounted in the stand (2) and each associated with the other units (7), said further pivot arms being pivotal in synchronism with said first pivot arm (32) for simultaneous actuation of the frames (9a-9f) of all units, the pivot arms (32, 46-49) carrying at their free ends (34) a lever (53) which can be swung against the action of a spring (56) connected to a lug (57) on said pivot arm (32) and to said lever (53) through a pin (52) extending through said free end (34) and which supports at its free end a freely rotatable roller (54) which when the pivot arms (32, 46-49) are swung in one direction first rolls on the outwardly facing side (58) of the frame (9b) last turned through substantially 180°, then on the outwardly facing side (59) of the frame (9a) which is to be turned next through substantially 180°, and finally past the free long edge (60) of said frame to be transferred by the action of the spring (56) actuating the lever onto the rearwardly facing said (61) of the frame, and when the pivot arms (32, 46-49) are swung in the other direction rolls on the rearwardly facing side (61) and turns the frame (9a) through substantially 180° so that the rearwardly facing side will be facing outwardly, whereupon the procedure is repeated.
