Abstract: A toy gear box having a gear case in which a worm wheel and a gear wheel having axes of rotation transversely to each other are in operative engagement with each other with a specific gear ratio. The gear wheel is replaceable, and at least one second gear wheel having a second number of teeth different from the first number may be inserted into the gear box, thereby imparting a second gear ratio to the gear box. The gear case (10) has a toothed rim in firm connection with the gear case (10), and the gear case (10) can receive such a toothed rim on another such gear case as a gear wheel.

Abstract: A rack and pinion with a rack (20) and a gear wheel (30) in operative engagement with each other, whereby movement of the rack (20) causes rotation of the gear wheel (30) and vice versa, and wherein an end stop is provided in the form of there being after the outermost gap (25) between teeth (21) at the end of the row of teeth (21) of the rack, instead of a gap, a “filled” gap or a plateau (26) which prevents a tooth (31b) on the gear wheel from getting into engagement. The bearing (11) of the gear wheel allows movement of the gear wheel relative to the rack in a direction transversely to the longitudinal direction of the rack, and by movement beyond the end stop the gear wheel will be pressed out of its bearing, and the mechanism is thereby protected against overloading.

Abstract: A toy building set is disclosed which includes a first type of building element formed of relatively flexurally flexible portions and a second type of building element having gripping fingers facing each other and spaced a distance apart that corresponds to the outer diameter of the flexurally flexible elements. The first type of building element may thus be releasably secured between the gripping fingers.

Abstract: A toy construction building set includes first and second building elements, which are releaseably interconnectable. The first building elements have a side with a coupling surface, which has coupling studs, and the second building elements have a side with a coupling surface, which has a skirt. Defined within the skirt is a cavity for receiving the coupling studs on the first building element. When the first and second building elements are interconnected, a first abutment portion of the first building element is outside the skirt and a second abutment portion of the second building element abuts the first abutment portion.

Abstract: A toy in the form of a shoe having a heel with a tread and a foresole with a substantially plane tread. The treads of the heel and the foresole being separated from each other. The toy additionally has a platform on which the shoe may be placed. The platform being shaped so that just the heel of the shoe forms a complementary coupling to allow the shoe to be detachably coupled to the platform.

Abstract: A stacking block system includes a plurality of blocks, each having a top face and a plurality of side walls extending downwardly from the top face. At least one coupling knob extends upwardly from the top face and has a substantially spherical upper part and a substantially cylindrical lower part. A tubular coupler or flange extends downwardly from the top face and beyond the side walls is complementary to the coupling knob, enabling coupling of two blocks. The tubular flange guides the coupling knob to enable coupling of two blocks, even when the blocks are tilted with respect to each other.

Abstract: A toy building set comprising a number of transmission elements in the form of a plurality of shafts and a plurality of toothed wheels, and a number of supporting elements for embedding of said transmission elements; and wherein the shafts have shaft extremities that are provided with splines in the form of a number of grooves spaced equally apart for mounting of one or more toothed wheels; and said toothed wheels having a central opening for receiving the spline of the shaft; and wherein the central opening on the toothed wheels is configured with one or more protruding flanges that engage with one or more of the grooves on the spline of the shaft with a view to ensuring that a toothed wheel mounted on a shaft is unable to rotate relative to the shaft; and wherein the toothed wheels are provided with a number of teeth that corresponds to or is equal to an entire multiple of the number of grooves on the spline of the shaft which makes it very easy to correctly mount the toothed wheels on the associated shafts

Abstract: A toy building set comprises building elements (11, 21, 22) of a first type with coupling studs (10, 20) arranged in a two-dimensional periodical pattern with the coupling studs (10, 20) disposed in rows in two main directions perpendicular to each other in such a manner that the coupling studs (10, 20) also form diagonal rows in diagonal directions relative to the main directions, whereby neighboring diagonal rows are separated by a space having a width (d) wider than zero, and building elements (11, 21, 22) of a second type for interconnecting with building elements (11, 21, 22) of the first type, said building elements (11, 21, 22) of the second type having pairs of parallel coupling walls (12, 23, 24) which define cavities with coupling means for receiving coupling studs (10, 20) on building elements of the first type in a releasable engagement in such a manner that the coupling walls (12, 23, 24) are arranged in main directions between rows of coupling studs, wherein the building set further comprises bu

Abstract: A toy building element (1) comprising a central portion (2) provided with at least one coupling means (3, 4) arranged axially relative to the central portion (2). Furthermore, the toy building element comprises at least one other coupling means (5, 6) arranged radially relative to the central portion (2), the at least one further coupling means (5, 6) being so arranged that it is able to rotate in excess of 360.degree. about the central portion (2).
