  • It is thereby possible to build constructions where one or more building blocks of different sizes are mounted onto the bistable band, and when the bistable band is urged to alter its shape from one stable position to another, then this will result in e.g. the ejection of the building blocks from the bistable band.
  • On the other hand the bistable band may e.g. be used as a slap bracelet allowing only building blocks that are covering only a single knob in a row on the bistable band to stay attached to the bistable band after it is slapped onto the wrist or other body part of the user. In this way it is possible to build different and customized slap bracelets, where the "single knob" blocks resembles ornaments on the slap bracelet.
  • In this relation the longitudinal direction means the direction where the bistable band has its longest measure.
  • In a preferred embodiment the second curvature axis extends at a distance from the second opposite side of the bistable band in order to ensure the highest possible stability of the two stable positions.
  • In this relation the bistable band may advantageously comprise a body made from a bistable metal band.
  • Furthermore the couplings knobs may advantageously be made from a plastic material attached to the bistable metal band by injection moulding.
  • In a preferred embodiment the bistable metal band is embedded in a plastic cover so that at least the edges of the band are covered by the plastic cover. In this relation the plastic cover may advantageously be injection moulded onto the bistable metal band, so that the bistable metal band is completely enclosed by the plastic cover, and where the plastic coupling knobs are integrally moulded with the plastic cover.
  • Preferably the coupling knobs are arranged in one, two or three, or even more rows extending parallel with the longitudinal direction of the bistable band.
  • Furthermore the length of the bistable band measured in the longitudinal direction of the bistable band may advantageously be so long that the ends in the longitudinal direction of the bistable band are overlapping when the bistable band is in said second stable shape being curved about the second curvature axis. Thereby the bistable band forms a closed loop when it is resting in its second stable position. The length of the bistable band in this relation furthermore be so that it may conveniently be curved about the wrist of a person when it forms a closed loop.
  • In this relation the rows of knobs may furthermore end at a distance from one end of the bistable band seen in the longitudinal direction, and so that the first side of the bistable band, when it is positioned in the second stable shape, abuts the second side of the bistable band.
  • In a preferred embodiment the number of toy building blocks comprises one or more building blocks without couplings knobs and having only one coupling socket adapted for frictional engagement with only one coupling knob of the bistable band.

    • Fig. 6: Is a cross section view of the bistable band in the stable position shown in figure 1.
    Description of exemplary embodiments:
  • Fig. 1 shows one embodiment of the bistable band 2 forming part of the toy construction set according to the present invention. In this embodiment the bistable band is formed in the shape as a slap bracelet 2, having coupling knobs 3 arranged in two parallel rows on the first side 7 of the slap bracelet. In this embodiment the slap bracelet is made from a bistable metal band 11 as shown in figure 5. Such bistable metal bands are well known in the art, and they provide the option of slapping the bracelet against e.g. the wrist of a person when it is in its first stable position as shown in figure 1, where the bistable metal band 11. Keeps the slap bracelet straight and having a curvature as shown in figure 5 about a curvature axis (not shown on the figures) extending along the longitudinal length of the slap bracelet, substantially parallel with the two rows of coupling knobs 3 arranged on the first side 7 of the slap bracelet.
  • By doing so the bistable metal band may be urged to be transformed from this first stable position and into the second stable position as shown in figure 4, where the bistable metal band curves about a second curvature axis (not shown in the figure) being substantially perpendicular to the first curvature axis.
  • In this embodiment the bistable metal band 11 is provided with a cover 14 of a soft and elastic plastic material extending so that it covers the sharp edges 13 of the bistable metal band 11.
  • The cover 14 is in this embodiment injection molded onto the bistable metal band 11, and for this reason holes 12 are extending through the cover 14 and into the bistable metal band 11. Apart from these holes 12, resulting from the necessity of using holding pins for positioning the bistable metal band in the correct position in the mold cavity of an injection molding tool, then the bistable metal band 11 is in this embodiment completely enclosed in the cover 14.
  • Figure 2 and 3 shows a building block 1 also forming part of the toy building set according to the present invention. Building blocks of this kind are well known in the prior art in various different shapes and embodiments all having a upper surface 4 with coupling knobs 3 arranged equidistantly in a square pattern, and a lower surface 5 having one or more sockets 6 arranged for frictional engagement with the coupling knobs 3 on the upper surface of another such building element 1, or according to the present invention with the couplings knobs 3 on the slap bracelet 2 shown in figure 1.
  • This is possible due to the fact that the rows of coupling knobs 3 on the slap bracelet 2 are arranged in accordance with the same square pattern as the coupling knobs 3 of the building element 1 shown in figure 2.
  • In this way the slap bracelet 2 may also be used as eg. a catapult for ejecting a building block 1 according to figure 2 and 3 away from the slap bracelet 2, if such a building element 1 is attached to the couplings knobs 3 on the slap bracelet 2 whereafter the slap bracelet 2 is urged to transform from the first stable position shown in figure 1 into the second stable position shown in figure 4.
  • On the other hand, when a smaller building element 10 as shown in figure 6, and having a coupling socket (not shown) arranged underneath and being shaped only for frictional attachment of the smaller building element 10 to a single coupling knob 3 on the slap bracelet, are attached to the slap bracelet, then this smaller building element may not be ejected from the slap bracelet 2, but stay on the slap bracelet as shown in figure 4.
  • Thereby the bistable band/slap bracelet 2 provides different options for the user to build constructions with very different functionality.
  • In this embodiment the slap bracelet 2 has opposite ends 9 being shaped without coupling knobs 3, so that first 7 and the second side 8 of the slap bracelet 2, having a length allowing the opposite ends to overlap, are directly in contact with each other.
