The present invention relates to an assembly kit including structural elements which are connectable with one another by interengaging undercut grooves and projections. More particularly, it relates to an assembly kit including a plate element and an axle element connectable with one another.
A plate element has been proposed in the art, having undercut grooves which are adapted to receive undercut projections of other structural elements so as to connect the latter with this plate element. When such several structural elements are connected with one another, there is possibility for insertion of an axle in the plate elements so as to assemble a vehicle structure. It has also been proposed to provide bores in the above plate elements, each of which bores forms an extension of a respective one of the undercut grooves, in order to increase a region of insertion. The axles are inserted into the above bores of the plate element.
The above known construction possesses some disadvantages. The positioning of the axle as described above is not suitable for an axle adapted to support wheels of the vehicle structure, inasmuch as the necessary stability thereof is not provided in the region of the undercut groove. Furthermore, at the place where the axle is inserted in the plate element there is no possibility to mount a further structural element on the plate element.
