Abstract
An electronic sign module housing having an overmolded gasket seal including an elastomer overmolded gasket seal with an inner and an outer lip and a base overmolded to a rearwardly located contact surface of an electronic sign module housing. Grooves on the contact surface of the electronic sign module housing provide additional bonding surfaces with a greater surface area to enhance the chemically-bonded overmolding of the overmolded gasket seal. Truncated conical projections extending forwardly from the elastomer base extend into correspondingly shaped truncated conical cavities in the electronic sign module housing in order to provide additional chemical bonding and to provide a geometrically based frictional engagement arrangement.
Claims26
An electronic sign module housing comprising:
- a plastic enclosure with an overmolded gasket seal, said plastic enclosure having a surrounding side wall;
- a rear wall at one end of said surrounding side wall;
- a front opening at an opposite end of said surrounding side wall for attachment of a display panel;
- said rear wall having a front surface and a rear surface;
- and,
- said overmolded gasket seal being attached and sealed to said rear surface of said rear wall of said plastic enclosure;
- wherein said overmolded gasket seal has an inner surface and an outer surface, and wherein said inner surface has a plurality of spaced truncated conical projections extending therefrom, and wherein said rear surface of said rear wall has a plurality of spaced truncated conical cavities that receive said spaced truncated conical projections during an overmolding process such that the truncated conical projections are located within the truncated conical cavities.
