A sign is provided having a rear plate (2) having at least two printed messages (5,6) and a front plate (3) arranged movably in front of the rear plate (2). The front plate (3) is arranged such that in its starting position it covers all the messages (5,6) on the rear plate (2), and that, by movement, it may be caused to expose at least one of the messages (5,6).
A sign comprising a rear plate (2, 32) having a least two section (5, 6,34,35) arranged in a row and a front plate (3,33) movably arranged in front of the rear plate (2,32) so that the front plate may be caused to selectively cover and uncover at least one section, said front plate being slidably interconnected with said rear plate, characterized in that the rear plate (2,32) additionally comprises at least one section (5,6,34,35) staggered with respect to the row, and in that the sign is arranged such that the front plate may be moved in two dimension relative to and in a plane parallel with the rear plate (2,32) so that the front plate (3,33) may be caused to selectively cover and uncover at least one section (5,6,34,35) in the row as well as sections staggered with respect to the row.

The invention relates to a sign comprising a rear plate having at least two sections arranged in a row and a front plate movably arranged in front of the rear plate so that the front plate may be caused to cover or uncover one or more sections.
Such a sign is known from e.g. DE-01-295 16 232 which shows a sign comprising a rear plate with two printed messages, a transparent cover plate and a front plate movably arranged between the rear plate and the cover plate. The rear plate is provided with two printed messages—“Unoccupied” and “Occupied”—and the movable front plate has a size such that it covers one message in its one extreme position, while it covers the other message in its other extreme position.
Another sign is known from U.S. Pat. No. 5,255,462. This sign comprises a front plate, a rear plate and a movable indicator plate. At one end the movable indicator plate has printed thereon an arrowhead which points in a direction opposite to an arrowhead printed at the other end of the indicator plate. The movable indicator plate is provided with a handle so that it may be placed in a position in which it is covered completely by the front plate, where just one arrowhead is visible, while the other is covered by the front plate, and vice versa. A line is printed on the front plate so that the sign can show either just a line or one of two oppositely directed arrows.
The invention will now be explained more fully with reference to the drawing, in which
FIGS. 1a-1d show a sign according to the invention in a preferred embodiment with the front plate in the starting position (FIG. 1a) and displaced in different directions (FIGS. 1b-1d),
FIG. 2 shows the sign of FIG. 1 in a disassembled state,
A sign 1 according to the invention is shown in FIGS. 1a-1d. The sign 1 is primarily useful as a name sign outside an office, but other uses of the sign 1 are also conceivable, as it may e.g. be arranged as a sign to be placed on a table.
The sign 1 comprises a rear plate 2 and a front plate 3, which is arranged in front of the said plate, and which may contain information in the form of text 4 on e.g. the name and the occupation of the person occupying that office. The front plate 3 is arranged to be movable in all directions relative to the rear plate 2 and may be caused, by moving, to expose one or more messages provided on the rear plate 2, as will appear from FIGS. 1b-1d. The messages may e.g. be text such as “Occupied”, “Unoccupied”, “At lunch”, “Meeting”, “The door is open”, etc.
Various messages 5 and 6 are provided on the rear plate 2 and may be exposed, as desired, by moving the front plate 3. In the starting position shown in FIG. 1a, none of the messages 5, 6 is exposed, and the sign then just contains information on e.g. the name and the occupation of the person occupying the office, via the text 4 on the front plate 3.
