Description

    The prior art:
  • 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.
  • 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.
  • 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.
  • 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:
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • In this relation the couplings sockets are preferably formed by a substantially cylindrical through hole extending through the building block.
  • 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.
  • 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.
    • The drawing:
  • In the following one or more embodiments of the invention will be described in more detail and with reference to the drawing, where:
    • Fig. 1: Is a perspective view showing one embodiment of a toy construction set according to the present invention before assembly.
    • Fig. 2: Is a perspective view of the toy construction set shown in fig. 1 after assembly.
    • Fig. 3: Is a detailed side view of one as shown in fig. 1 and 2.
    • Fig. 4: Is a side view of a connector pin to be used with the toy construction set shown in fig. 1 and 2.
    • Fig. 5: Is a side view of an alternative embodiment of the coupling pin according to the invention.
    Description of exemplary embodiments:
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • It is therefore apparent to the skilled person that the present invention is applicable to any such constructions, and toy construction sets.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
