Hanging device for establishing an electrically conductive contact with a hanging article and a monitoring system utilizing same

A hanging device for establishing an electrically conductive contact with at least one hanging article comprising:

• an elongated fastening unit adapted to be attached to a stationary surface, said fastening unit including at least two current paths;
• and
• at least one fastening element mountable to said fastening unit, said at least one fastening element being adapted to suspend said at least one hanging article along said stationary surface;
• wherein said at least one fastening element is provided with at least one contact which is adjustable to selectively establish said electrically conductive contact with at least one of said at least two current paths.

A hanging device for establishing an electrically conductive contact with at least one hanging article comprising:

• an elongated fastening unit adapted to be attached to a stationary surface, said fastening unit including at least two current paths;
• and
• at least one fastening element movably mounted to said fastening unit, said at least one fastening element being adapted to suspend said at least one hanging article along said stationary surface and being provided with at least one contact which is adjustable to selectively establish said electrically conductive contact with at least one of said at least two current paths;
• wherein said fastening unit includes a first trough-shaped part with a base and two side walls, and said at least one fastening element includes a downwardly opened U-shaped part with a base and two legs, a free end of a first leg being mechanically connected to the hanging article and a free end of a second leg being hung in said first trough-shaped part of said fastening unit.
