Abstract
Abstract A toy building set for building tree-like models and comprising partly a trunk element (FIG. 2), partly a branch element. The trunk element comprises a trunk portion (2) and projecting branches (3, 4) having coupling means (5, 6) spaced from the trunk portion (2). The branch element comprises a plurality of connecting bars (7-11), at whose ends coupling bushings (12) are provided. These bushings are formed with primary and secondary coupling means (17, 18), respectively, so that the branch elements may be interconnected and connected with the trunk elements. Preferably, said bars have additional branching portions (19, 20) whose ends are provided with bushings (21, 22) similar to the coupling bushings (12).

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
141 words
A toy building set for building tree-like models and including elements having primary and secondary coupling means adapted for interconnection, characterized by comprising in combination a plurality of elongate trunk elements, each of which has at least a primary and secondary coupling means, respectively, in its opposed ends, at least some of said trunk elements having elongate branching portions formed with coupling means of the aforementioned type at the ends thereof, and a plurality of substantially plane branch elements, each comprising a number of integral branch bars, at least some of which have primary and secondary coupling means which are adapted to be connected with the coupling means on the trunk elements wherein the primary coupling means and the secondary coupling means of a branch element extend from a primary side and a secondary side of the plane branch element, respectively.
Claim 2
Dependent Claim
141 words
A toy building set for building tree-like models and including elements having primary and secondary coupling means adapted for interconnection, characterized by comprising in combination a plurality of elongate trunk elements, each of which has at least a primary and secondary coupling means, respectively, in its opposed ends, at least some of said trunk elements having elongate branching portions formed with coupling means of the aforementioned type at the ends thereof, and a plurality of substantially plane branch elements, each comprising a number of integral branch bars, at least some of which have primary and secondary coupling means which are adapted to be connected with the coupling means on the trunk elements wherein the primary coupling means and the secondary coupling means of a branch element extend from a primary side and a secondary side of the plane branch element, respectively.
Claim 3
Dependent Claim
44 words
A building set according to claim 1, characterized in that at least the coupling means on the branch elements are constructed as a short bushing whose one end has an outside diameter corresponding to the inside diameter at the opposed end of the bushing.
Claim 4
Dependent Claim
32 words
A building set according to claim 1 or 2, characterized in that at least the bars of the branch elements are disposed in a plane transversely to the axes of the bushings.
Claim 5
Dependent Claim
51 words
A building set according to claim 3, characterized by additional bushings at the end of the branching portions of the branch elements, said additional bushings being disposed transversely to the plane of the branch element and constructed as the part of the coupling bushings which serves as a primary coupling means.
