Abstract
A device comprising a box having a transparent wall illuminated from the inside. The advertisements are joined to form a single flexible strip support which is wound and unwound between two parallel rollers. One of the rollers is fitted removably to the frame of the device, for enabling the support to be changed, and is rotated intermittently by an electric geared motor. The other roller is rotated by a torsion spring which provides for constantly tensioning the support.
Claims16
A device for displaying in a display window a series of advertisements, said device comprising a flexible strip support (18) including a plurality of advertisements (16), wherein said support (18) is wound and unwound between two parallel rollers (38, 39), and is fitted on one side to a first of said rollers (38, 39) and on the other side to a second of said rollers (38, 39);
- a reversible motor (41) for intermittently rotating at least said first roller (38) for successively displaying said advertisements (16) one at a time;
- elastic means (42, 162) acting on said second roller (39) for permanently maintaining said support (18) at a predetermined tension, said first roller (38) being angularly integral with a first pulley (63);
- and a flexible drive member (64) provided between said first pulley and a second pulley (66) rotated by said motor (41);
- and wherein said first roller (38) is fitted removably to a fixed frame (21) for enabling replacement of said support (18), said first roller (38) comprising, at one end, a bush (44) engaged by an elastic pin (45) movable elastically in an axial direction for enabling removal of said first roller (38) from said frame (21).
A device for displaying in a display window a series of advertisements, said device comprising a flexible strip support (18) including a plurality of advertisements (16), wherein said support (18) is wound and unwound between two parallel rollers (38, 39), and is fitted on one side to a first of said rollers (38, 39) and on the other side to a second of said rollers (38, 39), each said roller (38, 39) having a predetermined diameter;
- a reversible motor (41) for intermittently rotating at least said first roller (38) for successively displaying said advertisements (16) one at a time;
- and elastic means (42, 162) acting on said second roller (39) for permanently maintaining said support (18) at a predetermined tension;
- and wherein two lateral portions of each said roller (38, 39) present two bands (35) for increasing a diameter of the roller by 0.2 to 2 mm and correctly tensioning said support (18) over its full width.
A device for displaying in a display window a series of advertisements, said device comprising a flexible strip support (18) including a plurality of advertisements (16), wherein said support (18) is wound and unwound between two parallel rollers (38, 39), and is fitted on one side to a first of said rollers (38, 39) and on the other side to a second of said rollers (38, 39);
- a reversible motor (41) for intermittently rotating at least said first roller (38) for successively displaying said advertisements (16) one at a time;
- elastic means (42, 162) acting on said second roller (39) for permanently maintaining said support (18) at a predetermined tension;
- a front wall (29) carrying said front window (20), a frame (21) carrying said rollers (38, 39);
- and means for keeping said support (18) a given distance from said front wall (29);
- at least one brush (136) being fitted to a portion (138) of said frame (21) and having a number of wires (137) made of electrically conductive material and against which said support (18) brushes to discharge the static electricity accumulated in said support (18).
A device for displaying in a display window a series of advertisements, said device comprising a flexible strip support (18) including a plurality of advertisements (16), wherein said support (18) is wound and unwound between two parallel rollers (38, 39), and is fitted on one side to a first of said rollers (38, 39) and on the other side to a second of said rollers (38, 39);
- a frame (21) for mounting said rollers (38, 39) to a reversible motor (41) for intermittently rotating at least said first roller (38) for successively displaying said advertisements (16) one at a time;
- and a helical torsion spring (42, 162) mounted inside said second roller (39) for permanently maintaining said support (18) at a predetermined tension, said torsion spring (42, 162) having one end (92) fitted to a first flange (79, 157) in turn fitted to said second roller (39), said first flange (79, 157) being mounted for rotation on said frame (21), said torsion spring (42, 162) having another end fitted to a second flange (88, 159) in turn fitted to a shaft (84, 152) coaxial with said second roller (39), each said flange (79, 157;
