Claim 10

A construction toy comprising a plurality of flat members having flat sides formed with openings therein, separate coupling means for coupling said members and including resilient protrusions releasably engaging in said openings of said members to be coupled, said members being formed with surface recesses in said flat sides arranged axially symmetrically with respect to said openings, said coupling means including projections complementary in shape to that of said surface recesses and engaging therein when said members are coupled by said coupling means, said projections constituting at least two pins complementary in arrangement to that of said surface recesses, said coupling means constituting an angular coupling element, said flat members having beveled edges, said beveled edges forming 45 degree angles with respect to said flat sides, said members including flat bars having longitudinal edges formed with slots perpendicularly extending therefrom and aligned on opposite of said longitudinal edges and having a width equal to the thickness of said members, said beveled edges defining edge recesses therebetween, adjacent said openings, said edge recesses having a depth equal to half the thickness of said members and a length equal to half the width of said flat bars.

Claim 11

The construction toy as set forth in claim 8, wherein said members are formed with end slots which extend from said openings perpendicularly to a closest peripheral edge thereof and have a width equal to the thickness of said flat bars.

Claim 12

The construction toy as set forth in claim 8, wherein said edge recesses are centrally aligned with respect to an adjacent of said openings and have a length equal to a diameter of said adjacent openings.

Claim 13

The construction toy comprising a plurality of flat members having flat sides formed with openings therein, separate coupling means for coupling said members and including resilient protrusions releasably engaging in said openings of said members to be coupled, said members being formed with surface recesses in said flat sides arranged axially symmetrically with respect to said openings, said coupling means including projections complementary in shape to that of said surface recesses and engaging therein when said members are coupled by said coupling means, said projections constituting at least two pins complementary in arrangement to that of said surface recesses, said coupling means constituting an angular coupling element, said members including include flat bars having longitudinal edges formed with slots perpendicularly extending therefrom and aligned on opposite of said longitudinal edges and having a width equal to the thickness of said members, said flat members having edge recesses adjacent said openings, said edge recesses having a depth equal to half the thickness of said members and a length equal to half the width of said flat bars.
