Abstract

A toy building set comprising at least two toy building elements of which the one toy building element is provided with one or more coupling means of first type, and the second toy building element is provided with one or more coupling means of second type that is/are configured to be complementary to said coupling means of first type to the effect that they can be interconnected to form a structure, wherein the second toy building element comprises a flywheel ( 10 ) which is rotatably mounted on the toy building element, wherein the flywheel comprises one or more actuator mechanisms ( 21 ); and wherein the coupling means and the complementarily configured coupling means are configured such that the second toy building element can be mounted on the first toy building element in two or more different positions.

First claim

What is claimed is:

1. A toy building set comprising at least two toy building elements, a first toy building element provided with at least one or more coupling means of a first type, and a second toy building element provided with one or more coupling means of the first type and one or more coupling means of a second type, wherein said coupling means of the second type are configured to be complementary to said coupling means of the first type to the effect that they can be interconnected to form a structure such that the second toy building element can be mounted on the first toy building element in two or more different positions;
wherein the second toy building element comprises a connecting structure; a building-element coupling part, the building-element coupling part having four sides and being laterally connected via a side of one of the four sides to the connecting structure, the building-element coupling part comprising said one or more coupling means of the first type on a top surface thereof and said one or more coupling means of the second type on a bottom surface thereof; and a flywheel having an axle member;
wherein the connecting structure has a frame that encloses an inner region, and has a bearing therein for receiving the axle member of the flywheel which is rotatably mounted on the bearing, the frame of the connecting structure extending from a position on an axis of rotation of the flywheel, past the periphery of the flywheel to the building-element coupling part in a plane coinciding with a plane through the axis of rotation of the flywheel; and
wherein the flywheel comprises at least one actuator mechanism in the form of a toothed wheel which is functionally connected to the flywheel at a substantially perpendicular angle to a top surface of the building-element coupling part, wherein the toothed wheel is configured to engage with an actuator means, in the form of a rack, to the effect that the toothed wheel can transmit movement from rack to flywheel, whereby the flywheel is caused to rotate freely.

2. A toy building set according to claim 1 , wherein the connecting structure comprises positioning means for positioning the rack against the toothed wheel.

3. A toy building set according to claim 1 , wherein the flywheel is coupled to two toothed wheels.

4. A toy building set according to claim 1 , wherein the toothed wheel is connected to the flywheel in a rotation-resistant manner whereby the rotation force of the toothed wheel is transmitted to the flywheel.

5. A toy building set according to claim 1 , wherein the toothed wheel and the flywheel are securely connected to each other via the axle.
