Claim 1
Independent Claim
53 words
A wedge for use with lattice substructures of wall panels, comprising side walls and a back wall extending between said side walls, the wedge being bent from a sheet stamping, each side wall having a wedge surface formed at least partially by a bent edge region, each edge region having a toothed edge.
Claim 2
Dependent Claim
53 words
A wedge for use with lattice substructures of wall panels, comprising side walls and a back wall extending between said side walls, the wedge being bent from a sheet stamping, each side wall having a wedge surface formed at least partially by a bent edge region, each edge region having a toothed edge.
Claim 3
Dependent Claim
26 words
The wedge as defined in claim 1, wherein said back wall is formed with corrugations extended transversely relative to a direction of displacement of the wedge.
