Abstract
An article for dissipating accumulated static charges from a substantially insulated surface. The article comprises a single layer elongate conductor, having opposing ends, and at least one fastener located to join the opposing ends together to provide a continuous conductive loop in contact with the substantially insulated surface. The fastener further provides electrical connection to a ground cord for removal of accumulated static charge from the substantially insulated surface. A fastener may be either electrically conductive or electrically insulating provided it facilitates contact between the elongate conductor and a conductive portion of a ground cord.
Claims12
An article for dissipating accumulated static charges from a substantially insulated surface said article comprising:
- a single layer elongate conductor having opposing ends;
- and
- a fastener located for joining together said opposing ends to provide a continuous conductive loop in contact with the substantially insulated surface, said fastener further providing electrical connection including contact of said elongate conductor with a ground cord for removal of accumulated static charge from the substantially insulated surface.
An article for dissipating accumulated static charges from a substantially insulated surface said article consisting essentially of:
- a single layer elongate conductor having opposing ends;
- and
- a fastener located for joining together said opposing ends to provide a continuous conductive loop in contact with the substantially insulated surface, said fastener further providing a point of connection for a ground cord to remove accumulated static charge from the substantially insulated surface.
An adjustable, static dissipative strap for attachment to a limb to remove accumulated electrostatic charge therefrom, said strap comprising:
- a single layer elongate conductor having a first end opposite a second end;
- a dual purpose fastener at said first end of said elongate conductor as a means for joining said first end to said second end, said dual purpose fastener further providing connection for a ground cord;
- a plurality of holes formed at said second end of said elongate conductor for attaching said second end to said dual purpose fastener to provide a continuous conductive loop having size adjustment depending upon selection of one of said plurality of holes to engage said dual purpose fastener;
- and
- a plurality of openings formed between said first end and said second end to allow stretching of said elongate conductor to produce gripping contact of the conductive loop encircling the limb after wrapping said elongate conductor around the limb and joining said first end to said second end.
A device for conducting accumulated static charge from a substantially insulated surface to ground, said device comprising:
- a single layer elongate conductor having opposing ends;
- a ground cord connected to a ground plane;
- and
- a fastener located for joining together said opposing ends of said elongate conductor to provide a continuous conductive loop in contact with the substantially insulated surface, said fastener providing direct connection for said ground cord to conduct accumulated static charge from the substantially insulated surface to ground.
A process for removing accumulated static charge from a substantially insulated surface comprising the steps of:
- providing a static charge removal device comprising:
- a single layer elongate conductor having opposing ends;
- a ground cord connected to a ground plane;
- and
- a fastener located for joining together said opposing ends of said elongate conductor;
- shaping said elongate conductor to provide a continuous conductive loop in contact with the substantially insulated surface;
- joining said opposing ends using said fastener;
- and
- connecting said ground cord to said fastener to direct accumulated static charge from the substantially insulated surface to ground.
