BRIEF SUMMARY
CROSS REFERENCE TO RELATED APPLICATION
This application is a national phase of PCT/AT92/00019 filed 13 Feb. 1992 and containing subject matter disclosed in Austrian national application A 1570/90 of 26 Jul. 1990.
1. Field of the Invention
The invention relates to a foldable object such as an information carrier, container and the like, having two wings which can be folded and unfolded about a swing line, whereby wing surfaces are provided which can be folded down between the wings when the wings are folded and can be unfolded when the wings are opened, and the object consists primarily of a shape having projecting and recessed fold lines, so that when the wings are folded the wing surfaces can be fitted between the wings and when the wings are unfolded, the folded sheet forms an essentially flat surface when opened. The folded sheet has two main fold lines perpendicular to each other whose intersection point is located in the swing line of the two wings and whereby, starting from each point of intersection of the longitudinal fold lines with the main fold lines and perpendicular to the longitudinal fold lines, recessed fold lines parallel to the transverse fold line are provided.
2. Background of the Invention
Foldable objects such as street maps are known and described in U.S. Pat. No. 4,210,347. After unfolding both wings it is necessary to unfold and pull part the wing surfaces folded between the wings. Prior to folding, the wing surfaces have first to be folded correctly and arranged between the wings.
From the French published application 2 628 361 a foldable object of the aforementioned kind has become known. This object has the disadvantage that, similarly to the one disclosed in U.S. Pat. No. 4,210,347, parts of the wing surfaces have to slide into each other when the object is folded, which in practice leads to difficulties during folding and unfolding. Especially during rapid folding the wing surfaces can be damaged.
OBJECT OFF THE INVENTION
It is an object of the present invention to arrange the wing surfaces so that during the folding of the wings they will automatically come to lie between the wings without engaging one another and damaging the wing surface.
SUMMARY OF THE INVENTION
The present invention is characterized by the fact that parallel to the longitudinal fold lines and parallel to the mentioned recessed fold lines, respective projecting fold lines are provided, which intersect each other at right angles at an intersection point located on the main fold line.
According to further features of the invention the folded sheet is characterized by the fact that projecting fold lines arranged parallel to longitudinal fold lines and the segment of the transverse fold lines are arranged so that in the folded state of the foldable object the highest they can reach is up to the median longitudinal line.
BRIEF DESCRIPTION OF THE DRAWING
The above and other objects, features, and advantages will become more readily apparent from the following description, reference being made to the accompanying drawing in which:
FIG. 1 is a diagrammatic perspective view which shows schematically the object of the invention in a slightly unfolded state;
FIG. 2 is a diagrammatic plan view of the shape; and FIG. 3 is a perspective view of the partially folded object.
SPECIFIC DESCRIPTION
According to FIG. 1, the object has two wings 1, 2 which can be folded about swing or pivot line 3, as indicated by arrows. The wing surfaces 4, 5 lie between the two wings, when the object is folded.
FIG. 2 shows the paper sheet or a corresponding foil material and the fold lines arranged thereon. Projecting fold lines are shown in solid lines and form projecting edges during folding. Recessed fold lines are shown in broken lines.
On the backside (underside of the shape) there are stiffening sheets 31 not shown here in detail, but which can be seen much clearer in FIG. 3.
The folded sheet 15, which can be printed, has two basically diagonal main fold lines 6,7 which are perpendicular to each other. The intersection p
