The invention relates to a component part of a variable
building toy consisting of a jointing device for fastening cross
directional sheets, where the sheets are joined to each other
through slots, the width of which corresponds to the wall thick-
news in such a way that the slot of both sheets fits the non-
slotted part of the cross directional sheet. Each sheet has a
widening disposed along the longitudinal axis of the slot and in
at least one of the sheets the widening intersects with the slot
so that a three dimensional aperture is formed by the intersection
of the widening.
The widening may have different shapes, but since a
circular widening is the simplest, thus hereinafter the widening
will be referred to as the hole.
A jointing piece is arranged at the meeting point of the
hole, and is preferably a ball, prism, or cube, but could be any
other optional shape. The jointing piece may be inserted and
removed by use of the flexibility of the sheets, e.g. by bending
the part of the sheet around the hole to allow the jointing piece
to be inserted or removed. A solution is also conceivable, where
the jointing piece is sufficiently small to be inserted without
bending and after insertion it swells or expands in another way
and thus fastens the sheets.
If a set of holes is in the sheets and the jointing
pieces are objects, such as e.g. tennis balls, then after insert
lion the tennis balls not only hold the two sheets together, but
inversely the sheets are used as means of packing or for carrying
the tennis balls.

The sheets may be flat, curved or bent.
The invention thus comprises a component part of a
variable building toy in which cross-directional resilient sheets
are joined to each other by means of slots the width of which
corresponds to the thickness of the corresponding sheet so that
the sheets can be slid into each other along the slots with both
slots fitting onto a non-slotted portion of the corresponding
cross-directional sheet, wherein each sheet has at least one hole
of wider dimension than the slot, formed so that some portion of
the hole is disposed along the longitudinal axis of the slot, and
in at least one of the sheets the hole intersects with the slot in
the same sheet, so that a three dimensional aperture is formed by
the intersection of the holes at the junction of the sheets for
reception of a complementary jointing piece.
The invention is described in detail with the aid of
the drawings showing the jointing device according to the invent
lion given by way of example only.

In case of the solution shown in Figures 1
to 3, a slot 4 extending to half width of the sheets is
formed in a sheet 1 and 2. A circular widening pa is
on each end of the slot I The jointing piece yin this
solution it a ball pa.
In the solution shown in Figures 4 to I the
slots 4 formed in the 3heetsl and 2 extend similarly
to half width of the sheet. widening pa it formed in
the slot 4 of the sheet 1, while a hole 6 it formed in
a centerline above slot 4 of the sheet 2. naturally the
hole 6 is on the same level with the widening pa in the
other sheet I Here the jointing piece 3 it also a ball
pa.
In the solution shown in Figures 7 Jo 9, the
sheets 1 and 2 are held together by two jointing piece
I 3, in this case too by balls I Accordingly a slot 4
it formed in each sheet 1 and 2 and widening pa it part
of the slot. In addition a hole 6 is formed it the cent-
reline of each slot 4.
In the solution shown in Figures 10 to 12, the
jointing piece 3 it a prism 3b, The 910t9 4 formed in
the sheets 1 and 2 extend to half width of the sheets.
The widening formed at the end of slots 4 it urea shaped
corresponding to the prism 3b.
In the solution one in Figure 13 to 14, the
jointing place 3 is again a ball pa, but here jet of
glue

balls it used. Accordingly a long slot 4 is formed
in the eta 1 end 2, in which sever widening
5 and several holes 6 are Wormed it the centerline
of the slot 4.
In the solution shown in Figure 15 to 17,
the slots 4 oared in the sheets 1 and 2 ens shouter
than the half width ox both slots 4. The jointing
piece 3 is a ball pa in this solution too,
In the Louisiana shown in Figure 18 to 20,
the eta 1 and 2 are bent to cylindrical Shea
A widening pa it wormed in the slot 4 of the sheet
1, while a hole 6 it formed in the confine of the
slot 4 of the other sheet 2, naturally on the some
level with the widening Say
The sheets 1 and 2 are perpendicular to
each other or at least cry directional in relation
to each other in each solution and the widening 5
or hole 6 covering each other surround the jointing
piece 3 or other suitable body like a cave; thus it
can not fall out and the three pieces i.e. eta
1 and 2 and jointing piece 3 form a unit.
In order to insert the jointing Quacks thy
part ox the sheets along the jointing piece is bent
a one with dashed line in Figure 1, Bet it the
901ution where the bending it possible through the
plastic deformation of the sheet, that it the sheet
returns into it original Position after the jointing
piece it inserted. In order to rewove tune onto
piece, the part ox the sheet long the jointing piece
is to bebe~.Such solution it 8190 conceivable, where
the bending royalty in permanent deformation end aft
ton insertion of thy jointing piece or other holding
body, the sheet is bent back by hand.
The jointing dusks according to the invent
I lion is used to advantage in building toys or other

detachable structures or packing materials, when the Jointing piece used for fastening ox the sheets servos
a packed or mfls~ produced goods.
