Abstract

Abstract Panel (1) fitted with a casing (2) housing a number of display devices (3) arranged side by side and each fitted with a number of slats (8), the latter bearing on the display face (9) a portion of the graphic display and arranged so as to turn in loop formation, and with operating means (13, 13a) for moving the said slats on each display device simultaneously round the said loop in such a manner as to set one slat (8) on each display device selectively in a display position in which the said slat is arranged facing a window (5) on the front face (4) of the panel (1) with its display face (9) exposed and adjacent to that of the matching slats (8) on the other display devices.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 257 words
1 ) - Display panel ( 1 ) for changeable advertisements or information, the said panel ( 1 ) comprising a supporting element ( 2 ) supporting a number of display devices ( 3 ) arranged side and side and each designed to display, on the front face ( 4 ) of the said panel (1), a portion of the said graphic display, characterised by the fact that each said display device (3) comprises a number of slats (8), each having a display face (9) bearing the said portion of the graphic display and being arranged side by side so as to be aligned round an elongated loop, and means (13, 13a) for moving the said slats (8) simultaneously and by a preset amount round the said loop, while at the same time keeping the display face (9) on each slat (8) facing the outer side of the loop and essentially parallel at all times with the tangent of the said loop pass ing through the said slat (8), the longer axis of the loop travelled round by the slats (8) on each said display device (3) being essentially perpendicular to the said front face ( 4 ) on the said panel ( 1 ), so as to enable each slat (8) on each display device ( 3 ) to move selectively into a display position in which the said slat (8) is parallel with the said front face ( 4 ) on the panel ( 1 ) and has its display face (9) facing the same.
Claim 2
Dependent Claim 257 words
1 ) - Display panel ( 1 ) for changeable advertisements or information, the said panel ( 1 ) comprising a supporting element ( 2 ) supporting a number of display devices ( 3 ) arranged side and side and each designed to display, on the front face ( 4 ) of the said panel (1), a portion of the said graphic display, characterised by the fact that each said display device (3) comprises a number of slats (8), each having a display face (9) bearing the said portion of the graphic display and being arranged side by side so as to be aligned round an elongated loop, and means (13, 13a) for moving the said slats (8) simultaneously and by a preset amount round the said loop, while at the same time keeping the display face (9) on each slat (8) facing the outer side of the loop and essentially parallel at all times with the tangent of the said loop pass ing through the said slat (8), the longer axis of the loop travelled round by the slats (8) on each said display device (3) being essentially perpendicular to the said front face ( 4 ) on the said panel ( 1 ), so as to enable each slat (8) on each display device ( 3 ) to move selectively into a display position in which the said slat (8) is parallel with the said front face ( 4 ) on the panel ( 1 ) and has its display face (9) facing the same.
Claim 3
Dependent Claim 66 words
2 ) - Display panel ( 1 ) according to Claim 1, characterised by the fact that, in the said display position, the match ing slats (8) on the said display devices ( 3 ) are arranged essentially coplanar with their display faces (9) side by side, so as to form the said graphic display on the said front face ( 4 ) of the panel.
Claim 4
Dependent Claim 62 words
3) - Display panel (1) according to Claim 1 or 2 , characterised by the fact that the said supporting element ( 12 ) consists of a casing housing the said display devices (3) and having, on the said front face of the panel ( 1 ), a window (5) enabling the said slats (8) to be viewed in the display position.
Claim 5
Dependent Claim 90 words
4) - Display.panel (1) according to any one of the foregoing Claims, characterised by the fact that each said slat (8) is secured in removable manner to a pair of supports (11, 12) located at respective opposite ends of-the said slat (8) and connected to means ( 13 , 13 a) for guiding movement of the said slats (8) round the said loop, the said supports (1 1 , 1 2) being moved along the said guide means (13, 1 3a) by the said means for moving the said slats.
