Abstract
Abstract A toy construction set having a plurality of generally planar geometrically configured unitary multi-sided construction elements, with each side having a tab connected thereto with living hinges, each tab including an aligned pair of connectors, each connector including a generally cup-shaped protuberance, the exterior forming a male connector or pin and the interior forming a female connector or well. Adjacent connectors on a given tab are inverted relative to one another. A shaft member is provided with one end having a pin and the other end having a wall. A wheel carrying member is provided with horseshoe-shaped clip portions for engaging the periphery of the shaft member.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
191 words
In a construction set for constructing three dimensional objects, a unitary construction element comprising: a generally planar main body portion having at least three sides of the same length; spaced recesses in at least one of said sides having living hinges extending therefrom in a direction generally perpendicular to said at least one side; a tab having a side thereof secured to the other end of said living hinges with said tab side in proximate spaced relation to said at least one side; and first and second substantially identical aligned connector means on said tab each equally spaced from the midpoint of the length of said tab and each being of a cup-shaped configuration with said first connector means being in inverted relation to said second connector means, each of said cup-shaped connector means forming (a) a pin portion extending from one surface of said tab, and (b) a well portion in the opposite surface of said tab, said well portion being in axial alignment with said pin portion and being configured for frictional engagement with a corresponding one of said pin portions on another construction element having a like tab.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
25 words
The combination according to claim 1 wherein each side of said main body portion includes a like configured recess, hinge, tab and connector means arrangement.
Claim 4
Dependent Claim
24 words
The combination according to claim 2 wherein the length of said tab side is less than the length of said main body portion side.
Claim 5
Dependent Claim
32 words
The combination according to claim 1 wherein said construction element includes three sides and each side of said main body portion includes a like configured recess, hinge, tab and connector means arrangement.
