Abstract

Abstract A modular unit (10) for a building toy or model system is of shallow formation having sets of intercoupling projections (13, 14) on sides (11) thereof. The projections are of two types, each type interfitting with the other type so as to afford a choice of relative angular positions of interengaged members or so as to afford a choice of hinged and non-hinged interengagement.

Dependent Claim 25 words
A unit as claimed in claim 1 having edge projection formations of two types each to interfit with the other type on another modular unit.
Claim 4
Dependent Claim 24 words
A unit as claimed in claim 1 or 2 wherein said edge projection formations afford a choice of relative angular positions of interengaged units.
Claim 5
Dependent Claim 25 words
A unit as claimed in claim 1 or 2 wherein said edge projection formations afford a choice of hinged or non-hinged interengagement of modular units.
Claim 6
Dependent Claim 21 words
A unit as claimed in any one of claims 1 to 4 wherein said units have straight edges with said projections.
Claim 7
Dependent Claim 19 words
A unit as claimed in claim 5 having a set of each type of projection on different edges thereof.
Claim 8
Dependent Claim 45 words
A unit as claimed in any one of claims 1 to 6 wherein one type of projection is a lug with sideways spigot-like protrusions and the other type is a lug with grooves capable of accommodating the spigot-like protrusions of the one type of projection.
Claim 9
Dependent Claim 17 words
A unit as claimed in claim 7 wherein said spigot-like protrusions of each set are aligned together.
Claim 10
Dependent Claim 35 words

Dependent Claim 18 words
A unit as claimed in claim 9 wherein the lugs are to opposite sides of a hinging axis.
Claim 12
Dependent Claim 66 words
A unit as claimed in any one of claims 7 to 10 wherein a set of projections are in the form of lugs with thickening or ribs and a set of projections are in the form of lugs with recesses or grooves for accommodating said thickenings or ribs, the lugs of each set being staggered and alternating as their positions in the thickness of the unit.
Claim 13
Dependent Claim 56 words
A unit as claimed in any one of claims 7 to 11 wherein at least a set of lugs has sideways spigots extended as ribs on the lugs and at least a set of lugs has lugs with spaced grooves from each side and capable of accommodating either of a said spigot or a said rib.
