Abstract:
1. A system for assembly between a first sheet of glass including a first hole with countersunk surfaces on each of its sides and a second sheet of glass including a second hole with countersunk surfaces on each of its sides, comprising: a first connecting piece in said first hole, said first connecting piece being made of two elements and having a bore and further having conical surfaces that mate with the countersunk surfaces of the first hole; a second connecting piece in said second hole, said second connecting piece being made of two elements and having a bore and further having conical surfaces that mate with the countersunk surfaces of the second hole; a connecting core connecting with the first and second connecting pieces, wherein the connecting core comprises first and second parts, wherein the first part mates with the surface of the bore of the first connecting piece on which it exerts a force roughly parallel to an axis of the hole and the second part fits into the bore made in the second connecting piece therein to react to the force.
