The prior art:
[0001] The present invention relates to a toy construction set comprising a number of toy
building blocks forming a construction having multiple coupling sockets arranged in
a spatial or planar pattern, and where the toy building set further comprises a number
of coupling pins and a flexible sheet having at least one hole, and where each of
the coupling pins extends in a longitudinal direction between a first end being shaped
for releasable attachment of the pin to one of the coupling sockets, and a second
end extending away from the coupling socket in the attached position of the pin in
the socket, and where the second end of the pin comprises a head arranged distally
on a neck on the second end of the pin, and where the neck has a cross section allowing
it to pass freely through the hole.
[0002] Toy construction sets are known in various different embodiments, and as an example
US patent application no. 20170106309 discloses such a toy construction system, where the head of the coupling pins are
spherical, and it is possible to pass through the hole in the flexible sheet by elastic
deformation of the flexible sheet.
[0003] US patent no. 2885822 furthermore discloses a toy construction set having coupling pins with a head having
a size preventing that the head can be shifted through the hole in the flexible sheet.
[0004] The toy construction sets provides many different options for attaching sheet elements
to a rigid structure constructed with the building blocks.
The object of the invention:
[0005] On this background it is the purpose of the present invention to provide a construction
set as mentioned in the introduction, and providing the user with further options
for easily building more different constructions with new and intriguing functionality.
[0006] This is obtained by the toy construction set according to claim 1 by having the size
and shape of the hole and the size and shape of the head are adapted such that it
is impossible to pass the head through the hole without tearing or providing a plastic
deformation on the flexible sheet, and by having the neck extending between the head
and a flange surrounding the pin and the size and shape of the flange being such that
passing the flange through the hole requires plastic deformation of the flexible sheet.
[0007] Thereby the flexible sheet is easy to attach to the coupling pin, but at the same
time it is impossible to detach from an assembled construction as long as the coupling
pin is mounted in a coupling socket.
[0008] In a preferred embodiment of the invention the head of the coupling pin is shaped
like a panhead having a flat surface on the side of the head where the neck of the
coupling pin is arranged, and a convex surface on the opposite side. Thereby the risk
of tearing the flexible sheet is reduced if a force is applied to the sheet trying
to pull the sheet over the head.
[0009] In a preferred embodiment of the invention the largest cross section of the head
is in a direction perpendicular to the longitudinal direction larger than the largest
cross section of the hole in the flexible sheet.
[0010] In a further preferred embodiment the hole in the flexible sheet, and the largest
cross section of the head in a direction perpendicular to the longitudinal direction
are both circular.
[0011] Preferably the construction set comprises one or more of said building blocks, each
having multiple coupling sockets arranged equidistantly at least along one straight
line.
[0012] The construction set according to the invention may advantageously comprise two or
more of said building blocks, and at least one connector pin having a first end adapted
for being attached to a coupling socket on one of said building blocks, and an opposite
end adapted for being attached to a coupling socket on the other one of said building
blocks.
[0013] In an especially advantageous embodiment of the invention the flexible sheet is made
from an elastically bendable material. Thereby the bending elasticity of the flexible
sheet, along with the secure attachment of the sheet to the coupling pin provides
various new functionalities without the risk that the flexible sheet disengages from
the coupling pin.
[0014] In this relation the couplings sockets are preferably formed by a substantially cylindrical
through hole extending through the building block.
[0015] The invention also provides a computer-readable model comprising computer-readable
instructions configured to cause, when processed by an apparatus for performing an
additive manufacturing process, said apparatus to manufacture the toy building elements
as defined above.
[0016] Furthermore the invention provides a method of assembling at toy construction set
according to one or more of the preceding claims, wherein the coupling pin is first
attached to the flexible sheet by passing the first end of the coupling pin through
the hole in the flexible sheet, and thereafter the first end of the coupling pin is
attached to the coupling socket of one of the toy building blocks.

Description of exemplary embodiments:
[0018] Fig. 1 shows a very simple embodiment of a toy construction set according to the
invention, having only a single building block 1, a flexible sheet 2, and a coupling
pin 3 adapted for interconnecting the building block 1 with the flexible sheet 2 to
form a combined construction.
[0019] The building block 1 has two legs forming a V, and each of the legs has a row of
coupling sockets 4 arranged equidistantly along a straight line, and being formed
as cylindrical through holes with a recess 5 arranged at each end of the through hole.
[0020] In the end of each of the legs on the building block 1 a second type of coupling
socket 4a are arranged being formed as a splined through hole.
[0021] Building blocks of this type, are well known in the prior art having many different
shapes and sizes allowing the user to construct various different structures e.g.
by interconnecting two or more such building blocks using a connector pin 17 as shown
in figure 4 formed as a cylindrical pin having oppositely arranged ends that extend
away from a mid-flange 18, and due to the cutouts 20, and the distally arranged end
flanges 19 each may be snap fitted into one coupling socket 4 on two different building
blocks, so that the mid-flange 18 and the end flanges 19 fits into the recesses 5
on each end of the coupling sockets 4.
[0022] In this way it is possible to construct both simple and complex and rigid or articulating
structures such as toy sailing ships, toy tents, toy flag poles and the like, and
by providing the opportunity of mounting a sheet 2 on such structures, then it is
possible to construct such toy structures that more realistically resembles real such
sailing ships, tents, flag poles and the like, where the sheet 2 respectively resembles
the sails, the tent canvas or the flag.
[0023] It is therefore apparent to the skilled person that the present invention is applicable
to any such constructions, and toy construction sets.
[0024] According to this embodiment of the invention the sheet 2 has a hole 10 and is possible
to attach to the building block/building element 1 by using a substantially cylindrical
coupling pin 3 as shown in figure 1 and 3 by inserting the first end 11 of the substantially
cylindrical coupling pin 3 through the hole 10 in the sheet 2, and into a snap engagement
with one of the coupling sockets 4 formed by cylindrical through holes in the building
block 1. According to this embodiment of the invention the head 7 of the coupling
pin 3 has a cross section in a plane being perpendicular to the longitudinal symmetry
axis 12 of the coupling pin 3 that is much larger than the width of the diameter of
the circular hole 10 in the sheet, so that it securely attached to the building block
1 due to the fact that it is impossible to pass the head 7 through the hole 10 without
tearing or providing a plastic deformation of the sheet 2.
[0025] It will be apparent to the skilled person that it is possible, according to the invention,
to design various different shapes and sizes of the hole 10 in the sheet 2 and corresponding
shapes and sizes of the head 7 of the coupling pin 3, and to select a sheet material
og the sheet 2 having an elasticity so that it is not possible to pass the head 7
thorough the hole 10 without tearing the material of the sheet 2 or at least forming
a permanent/plastic deformation of the sheet material around the hole 10.
[0026] As an example the sheet 2 shown in figure 1 and 2 also has a second hole 10a, being
triangular with a side length so that it allows the intermediate flange 9 mentioned
below to pass the hole 10a.
[0027] In the embodiment shown in figure 1 and 3 the head 7 is formed as a panhead having
a flat surface on the side facing the sheet 2 and a convex surface 16 facing away
from the sheet 2 when it is attached to the coupling pin as shown on figure 3. In
this embodiment the coupling pin 3 also has a neck 8 extending between the panhead
10 and an intermediate flange 9, and the diameter of the flange is in this embodiment
smaller than the diameter of the hole 10, whereas the diameter of the flange 9 is
a little larger than the diameter of the hole 10, so that is possible to pass the
flange 9 through the hole 10 by elastic deformation of the sheet. Thereby it is possible
to attach the coupling pin 3 to the sheet 2 without the risk of losing the coupling
pin 3 when handling the sheet 2 before it is attached to the building block 2 as shown
on figure 2.
[0028] In some embodiments the holes have a triangular shape. This allows the flange to
pass through the hole by elastic deformation of the hole while reducing the risk of
damaging the sheet.
[0029] In the same way as the connector pin 17 is possible to snap into one of the coupling
sockets 4 on the building element, then the coupling pin 3 shown in figure 3 is possible
to snap into any one of the cylindrically shaped coupling sockets 4 on the building
block 1, where the intermediate flange 9 fits into the recess 5 on one side of the
coupling socket 4. In this way the same coupling socket 4 may be used for either interconnecting
building blocks 1 or for attaching coupling pins 3.
[0030] In this relation this embodiment of the invention also comprises a second type of
coupling sockets 4a that are shaped as splined through holes where a second type of
coupling pin 24 as shown in figure 5 having a splined axle end are to be inserted
into and held in place by friction.
