Abstract

A plurality of arcuate beam elements each having ends defining coupling mechanisms is assembled in an interlocking framework using a plurality of multiply couplable couplers to form arcuate segments which define a sphere or portion of a sphere. A plurality of spherical inserts each defining a one-eighth spherical segment is assembled to the spherical framework to complete a sphere or spherical segment using a snap-fit attachment.

Claims

1. A spherical element combination construction toy comprising:

a framework for a sphere or spherical portion having a plurality of arcuate beam elements each defining an arcuate body having ends defining a first snap-fit connector structure and a plurality of couplers each defining a plurality of second snap-fit connector structures, said second snap-fit connector structures cooperating with said first snap-fit connector structures to interlockably connect said plurality of arcuate beam elements to form said framework for a sphere or spherical portion;

a plurality of spherical inserts each defining an approximate one eighth segment of a sphere; and

means for snap-fit attaching said spherical inserts to said framework to complete a sphere or spherical portion.

2. A spherical element combination construction toy as set forth in claim 1 wherein said framework includes eight arcuate beam elements and five couplers and forms a hemispherical frame.

3. A spherical element combination construction toy as set forth in claim 2 wherein said framework supports four spherical inserts to complete a hemisphere.

4. A spherical element combination construction toy as set forth in claim 1 wherein said framework includes twelve arcuate beam elements and six couplers and forms a spherical frame.

5. A spherical element combination construction toy as set forth in claim 4 wherein said framework supports eight spherical inserts to complete a sphere.

6. A spherical element combination construction toy comprising:

a framework for a sphere or spherical portion having a plurality of arcuate beam elements each defining an arcuate body having ends defining a first snap-fit connector structure and a plurality of couplers each defining a plurality of second snap-fit connector structures, said second snap-fit connector structures cooperating with said first snap-fit connector structures to interlockably connect said plurality of arcuate beam elements to form said framework for a sphere or spherical portion;

a plurality of spherical inserts each defining an approximate one eighth segment of a sphere; and

means for snap-fit attaching said spherical inserts to said framework to complete a sphere or spherical portion including a plurality of bosses, each defining a concave recess, supported upon said arcuate beam elements and a plurality of projections extending from said spherical inserts, each of said projections being received within cooperating recesses in said bosses when one of said spherical inserts is fitted to said framework.

7. A spherical element combination construction toy as set forth in claim 6 wherein said framework includes eight arcuate beam elements and five couplers and forms a hemispherical frame.

8. A spherical element combination construction toy as set forth in claim 7 wherein said framework supports four spherical inserts to complete a hemisphere.

9. A spherical element combination construction toy as set forth in claim 6 wherein said framework includes twelve arcuate beam elements and six couplers and forms a spherical frame.

10. A spherical element combination construction toy as set forth in claim 6 wherein said framework supports eight spherical inserts to complete a sphere.
