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.

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
A unit as claimed in claim 8 wherein the lugs of each set corresponding to a side of the unit are staggered and alternating as to their heights relative to the thickness of the unit.
Claim 11
Dependent Claim
18 words

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.
Claim 14
Dependent Claim
18 words
