[0001] The present invention provides a composite folding sheet, characterized in that this
folding sheet may be folded open- or over a number of times from a bordering or separating
line located in the middle of the folding sheet to an even further folding position
to return again finally to the initial position.
[0002] With this composite folding sheet it is possible, without turning the folding sheet
as a whole, to obtain in the various folding positions surfaces which may be provided
with text and/or pictures, so that by the 'folding on' of the folding sheet for instance
a short stripcartoon might be passed through.
[0003] The composite folding sheet according to the invention may differently be carried
out.
[0004] In a favourable embodiment of the invented folding sheet, the bordering- or separating
lines in the succeeding folding positions have been rotated alternatively over an
angle of 90 degrees in respect to each other.
[0005] In a preferred embodiment of the composite folding sheet according to the invention,
this is formed out of four conform, hexagonal parts with each two middle lines of
symmetry extending perpendicularly in respect to each other, in which each part consists
of a rectangular middle portion, to which over two rectangular sides which are located
opposite each other and are formed as folding lines, two triangular parts connect,
while the four hexagonal parts are placed in two pairs next to each other, and in
which the one pair is placed as being rotated over an angle of 90 degrees in respect
to and over the other pair, and the four hexagonal parts are adhered to each other
at the outwardly directed halves of the triangular parts such, that the two, next
to each other located hexagonal parts of each pair from the common, bordering- or
separating line located in the middle of the folding sheet, may be rotated in a direction
perpendicular thereon over an angle of 180 degrees around the middle symmetry line,
extending parallel to the bordering- or separating line. In this last preferred embodiment
of the composite folding sheet according to the invention, four folding positions
may be obtained by going through the folding sheet, that is to say, by folding the
folding sheet on and on, in which for instance a stripcartoon may be reproduced.
[0006] After folding on the fourth folding position, the first, initial folding position
is gotten back.
[0007] The invention will be further explained by way of example with reference to the accompanying
drawing.
[0008] In the drawing the figures 1, 2, 3, and 4 show four succeeding folding positions
of the composite folding sheet according to the invention.
[0009] As is shown more in particular in Fig. 1 and Fig. 4, the composite folding sheet
is formed by a, in Fig. 1 upperlying first pair of two, conform hexagonal parts, placed
next to each other, and underneath which, as being rotated over an angle of 90 degrees
in respect to the first pair, a corresponding second pair of hexagonal parts is arranged,
and which is shown more in particular in Fig. 4. The first pair (a) is, irrespective
the front or back side of the parts, shown darkly tinted, while the second pair (b)
has remained untinted.
[0010] Further the corresponding elements of both pairs are indicated with the same reference
numbers, however with this difference, that the reference numbers of the first pair
has been completed with the character -a- and those of the second pair with the character
-b-.
[0011] As more in particular is shown in Fig. 1 and Fig. 4, each hexagonal part consists
of a rectangular middle part 1a, resp.1b, to which over the folding lines 2a, resp.
2b, the triangular parts 3a, resp. 3b, are connected.
[0012] Both pairs are connected to each other at the outwardly directed halves of the parts
3a and 3b, as is shown by little crosses in Fig. 1 and in Fig. 4, such as by means
of glueing of these halves to each other.
[0013] Starting from the initial position according to Fig. 1 , both upperlying hexagonal
parts 1a, 3a may be rotated from the common separating line 4a in the direction of
the arrows around the middle symmetry lines 5a to abutment with the underlying parts
pair, and by which then the folding position according to Fig. 2 arises, in which
the rectangular middle parts 1b of the second pair have come on top.
[0014] By folding over then upwards and downwards around the middle symmetry lines 5b of
the second pair (b) from the separating line 4b of this second pair, the folding position
according to Fig. 3 arises, and in which then the middle parts 1a of the first pair
appear at the upper side of the folding sheet.
[0015] During the succeeding rotation of the middle parts 1a of the first pair (a) around
the middle symmetry lines 5a from the separating line 4a in the direction of the arrows,
the folding position according to Fig. 4 arises, in which the second pair (b) has
come on top.
[0016] When, at last, at the folding position according to Fig. 4 the second pair 1b, 3b
from the separating line 4b in the direction of the arrows are rotated around the
middle symmetry lines 5b, the folding position according to Fig. 1 arises again.
[0017] Thus, a short stripcartoon may be reproduced by the folding sheet, during which by
folding the folding sheet over or on, the succeeding pictures and text of the cartoon
may be exposed.
1. Composite folding sheet, characterized in that this may be folded open- or over
sideways from a bordering- or separating line situated in the middle of the folding
sheet to an even further folding position, to return again eventually to the initial
position.
2. Composite folding sheet according to claim 1 , characterized in that the bordering-
or separating lines in the succeeding folding positions have been rotated alternatively
over an angle of 90 degrees in respect to each other.
3. Composite folding sheet according to claim 1 or 2, characterized in that this is
formed out of four conform, hexagonal parts, with each two middle lines of symmetry
extending perpendicularly in respect to each other, in vhich each part consists of
a rectangular middle part, to which over two rectangular sides, which are located
opposite each other and which are formed as folding lines, two triangular parts connect,
while the four hexagonal parts are placed in two pairs next to each other, and in
which the one pair is placed as being rotated over an angle of 90 degrees in respect
to and over the other pair and the four hexagonal parts are adhered to each other
at the outwardly directed halves of the triangular parts , such, that the two, next
to each other located hexagonal parts of each pair from the common, bordering- or
separating line located in the middle of the folding sheet may be rotated in a direction
perpendicular thereon over an angle of 180 degrees around the middle symmetry line,
extending parallel to the bordering- or separating line.
