Abstract

An adapter for use in combination with an electric dryer to electrically connect the dryer to an outlet when the pattern of the prongs on the power cord plug do not correspond to the pattern of the prong-receiving receptacle openings at the outlet. In the preferred embodiment, the adapter comprises an adapter body having a plurality of prong-receiving openings on its outward face and a plurality of adapter prongs on its rearward face. The prong-receiving openings are in a first prong pattern that corresponds to the number and/or configuration of the prongs on the plug and the adapter prongs are in a second prong pattern that corresponds to the number and/or configuration of the receptacle openings on the outlet to electrically interconnect the plug and the outlet. In one embodiment, the adapter also includes a connecting wire inside the adapter body and a ground wire to ground the dryer.

Claims (19)

1. An adapter comprising:

a body member having an outward face at a first end and a rearward face at a second end;

three prong-receiving openings in said outward face of said body member, said prong-receiving openings disposed in a first prong pattern in corresponding relation to three plug prongs on a power cord electrically connected to a dryer, said plug prongs on said power cord disposed in non-corresponding relation to four receptacle openings of an outlet such that direct connection of said power cord to said outlet is prevented;

four outwardly extending adapter prongs on said rearward face of said body member, said adapter prongs disposed in a second prong pattern in corresponding relation to said plurality of receptacle openings of said outlet so as to allow said power cord to electrically connect said dryer to said outlet when said plug prongs of said power cord are positioned in said prong-receiving openings of said adapter plug and said adapter prongs are positioned in said receptacle openings of said outlet; and

a ground wire extending outwardly from said body member to connect to said dryer and a connecting means associated with said body member for electrically connecting one of said adapter prongs with said ground wire.

2. The adapter of claim 1 further comprising an attachment means on said ground wire for attaching said ground wire to said dryer.

3. The adapter of claim 2 , wherein said attachment means comprises one or more eyelets.

4. The adapter of claim 2 , wherein said attachment means is a clamp.

5. The adapter of claim 1 further comprising an extending means associated with said body member for retractably extending said ground wire from said body member to said dryer.

6. An adapter comprising:

a body member having an outward face at a first end and a rearward face at a second end;

three prong-receiving openings in said outward face of said body member, said prong-receiving openings disposed in a first prong pattern in corresponding relation to said plug prongs on a power cord electrically connected to a dryer, said plug prongs on said power cord disposed in non-corresponding relation to a plurality of receptacle openings of an outlet such that direct connection of said power cord to said outlet is prevented;

four outwardly extending adapter prongs on said rearward face of said body member, said adapter prongs disposed in a second prong pattern in corresponding relation to said receptacle openings of said outlet so as to allow said power cord to electrically connect said dryer to said outlet when said plug prongs of said power cord are positioned in said prong-receiving openings of said adapter and said adapter prongs are positioned in said receptacle openings of said outlet;

a ground wire extending outwardly from said body member to connect to said dryer;

connecting means associated with said body member for electrically connecting one of said adapter prongs to said ground wire; and

attachment means on said ground wire for attaching said ground wire to said dryer.

7. The adapter of claim 6 , wherein said attachment means comprises one or more eyelets.

8. The adapter of claim 6 , wherein said attachment means is a clamp.

9. The adapter of claim 6 further comprising an extending means associated with said body member for retractably extending said ground wire from said body member to said dryer.
