DESCRIPTION OF EXEMPLARY EMBODIMENTS

[0023] 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 FIG. 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 FIG. 1, where the bistable metal band 11. Keeps the slap bracelet straight and having a curvature as shown in FIG. 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.

[0024] 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 FIG. 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.

[0025] 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.

[0026] 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.

[0027] FIGS. 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 FIG. 1.

[0028] 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 FIG. 2.

[0029] In this way the slap bracelet 2 may also be used as eg. a catapult for ejecting a building block 1 according to FIGS. 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 FIG. 1 into the second stable position shown in FIG. 4.

[0030] On the other hand, when a smaller building element 10 as shown in FIG. 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 FIG. 4.

[0031] Thereby the bistable band/slap bracelet 2 provides different options for the user to build constructions with very different functionality.

[0032] 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.
