FOLDABLE OBJECT SUCH AS INFORMATION CARRIER, CONTAINER AND THE LIKE
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 shape forms an essentially flat
surface, the shape 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.
Foldable ob~ects such as street maps are known and described
in the US Patent 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. ~his object
has the disadvantage that, similarly to the one disclosed in US
Patent 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
precipitated folding the wing surfaces can be damaged.

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.
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 riqht angles in
intersection point located on the main fold line.
According to further features of the invention the shape is
characterized by the fact that projecting fold lines arranged
parallelly 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.
Further features of the invention can be found in the patent
claims and in the following description, as well as in the drawing.
In the following the invention is closer described with the
aid of an embodiment example. Fig. 1 shows schematically the
object of the invention in a slightly unfolded state. Fig. 2 shows
a top view of the shape and Fig. 3 an oblique view of the partially
folded object.
According to Fig. 1, the object has two wings 1, 2 which can
be folded about swing 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 shape cut out of paper 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
~urfaces 31 not shown here in detail, but which can be seen much
clearer in Fig. 3.
The shape 15 has two basically diagonal main fold lines 6, 7
which are perpendicular to each other. The intersection point 8 of
the two main fold lines lies in the swing line 3 of the two wings
1, 2. The fold line segments 11, 12 and 9, 14 are recessed, while
the fold line segments 10, 13 are projecting. Further through the
intersection point 8 runs a transverse fold line 16 formed by two
pro~ecting fold line segments 17, 18.
.
Further two longitudinal fold lines 23, 24 are provided, the
left longitudinal fold line 23 consisting of two fold line segments
21 and the right longitudinal fold line 24 consisting of two fold
line segments 22. Defined by the respective fold line segments 11,
21, 22 and the shape edge 33 or 34, base surfaces 19, 20 are formed
which basically constitute the wings 1, 2 and are connected,
particularly glued to stiffening surfaces 31. The two base
surfaces 19, 20 meet each other at the intersection point 8.
.
From the intersection points 25 of the longitudinal fold lines
23, 24 with the main fold lines 6, 7, perpendicularly with respect
to the longitudinal fold lines 23 24, recessed fold lines 26
parallel to the transverse fold line 16 are provided. Further,
parallelly to the aforementioned fold lines 21 and 26, projecting

9044
fold lines 27, 28 are arranged so that they are offset towards the
corners of the shape, whereby these fold lines intersect each other
in the intersection point 29 on the main fold lines 6, 7.
When the object is folded, the base surface ~9 is folded down
about the swing line 3. Thereby the fold line segment 17 performs
a motion according to arrow 35 and the fold line segment 28 is
moved according to arrow 36. In the folded state of the object,
the pro~ecting edge formed by the fold line segments 16 and 28
a~sume a position as indicated with 37 in broken lines. According
to arrow 38, the fold line segment 27 comes to lie over the fold
line segment 28 and thereby also assumes the position indicated in
broken lines by 37. When the object is folded, the fold line
segment 13 (and by analogy the fold line segment 10) of the main
~old lines 6, 7 assumes the position indicated by the broken line
39. The various positions of the projecting fold line segments are
shown only in the lower left corner of Fig. 2. Analogous
conditions exist also at the other three corners of the shape.
,
Fig. 3 shows the object according to Fig. 2 in semi-folded
state, whereby also the wings 1, 2 which are formed by the base
.~
- surfaces 19, 20 and the stiffening surfaces 31, are at an angle of
approximately 90 degrees with respect to each other. Similar parts
- show similar reference numerals, so that the figure is self--
exp1anatory.
