Embodiment Construction

[0030] The toy building block 1 has a key 3 on its top surface 4 and one or more grooves 6 on its bottom surface 7 (Fig. 3). The key 3 has a gear-like cross-section, the teeth 9 and the gaps or grooves 10 therebetween are rounded. In particular, they constitute a circular arrangement of substantially circular cross-section, with alternating directions of curvature. In the example, the absolute value of the curvature of the crest 12 is significantly higher than the curvature of the groove 10 . The cross-section of the key is eightfold symmetrical, that is, the teeth are arranged in a regular octagon.

[0031] Due to this rotational symmetry, the key 3 block can be connected to another block 1 with a fixed rotation direction - the direction of rotation can vary by 45°, that is, the two blocks can be in a straight line, cross (90°) and at 45° ° angle. Therefore, various three-dimensional arrangements can be constructed.

[0032] Complementarily, the groove 6 on the bottom of ...

Abstract

A toy building block (1) for stacking is provided on top (4) with one or more studs (3) and in the bottom (7) with recesses (6). The studs (4) show a toothwheel-like cross-section with rounded teeth crests (12) and rounded grooves (10) between the teeth (12) as well. The recesses (6) are provided each with a number of vertically extending lands (14) matching in shape the grooves (10). The studs easily slide in and out of the recesses (6), yet a rotational arretation of low play is obtained. Preferably, the building blocks are produced by a blowing process and may be provided with screws (21) for a safe interconnection. External slots (46) may allow the combination with panels (47) bearing images, additional functional elements etc. <IMAGE>

Description

technical field [0001] The invention relates to a toy building block according to the preamble of claim 1 . The invention also relates to a screw suitable for toy building blocks according to the preamble of claim 11 and a screwdriver according to claim 14 . Background technique [0002] Toy blocks intended to be stacked one on top of the other typically have studs on their top surface and corresponding grooves on their bottom surface. The key can be pushed into the groove with a greater or lesser force, wherein the bonding force is related to the strength of the mutual connection established between the two building blocks. After several rounds of connection and separation, the strength generally weakens, and the connection strength decreases with the increase of rotational play. In particular, the assembly of new building blocks requires considerable force making it less suitable for smaller children. [0003] Another measure is the ability and ease of building three-di...
