Patent Images
1. An item of hardware adapted to be adhesively bonded to a substrate comprising:
- an integral housing portion comprising;
a hardware functional portion;
a housing peripheral portion extending from the hardware functional portion containing a base plate having one or more adhesion-enhancing openings formed therein and oriented substantially parallel to the surface of the substrate to which it is to be adhesively attached;
a continuous housing peripheral extension portion extending from the housing peripheral portion and circumferentially encompassing the base plate, the housing peripheral extension portion contacting the substrate surface in a manner so as to exert a uniform pressure on the glass surface of about 6,000-24,000 psi.
