Abstract

A magnetic connection assembly for releasably connecting a ground cord to an electrically conductive body band. Said assembly comprising a first connection member electrically connected to one end of a ground cord and a second connection member electrically connected to a body band. The first and second connection members are at least partially formed of electrically conductive material and are correspondingly sized and configured so as to be relatively positionable in a "coupled" relation, whereby electrical contact is maintained therebetween. At least one magnet is positioned in at least one of the first and second connection members so as to create sufficient magnetic attraction therebetween to hold the first and second connection members in their "coupled" relation without the need for frictional or spring loaded snaps and the like.

Claims

1. An antistatic body band and ground cord assembly for conducting static electricity away from the wearer'"'"'s skin, the assembly comprising:

(a) a body having an upper surface and a lower surface, the lower surface having a recess formed therein;

(b) a conductive bottom plate disposed partially within the recess of said body and having an aperture formed therein;

(c) an elastic strip having first and second ends and having conductive fibers woven therein, the first end of said strap having an aperture formed therein and being captured intermediate said bottom plate and said body, the second end of said strap being attachable to said body;

(d) a ferromagnetic flange disposed upon the upper surface of said body, said flange having a generally planer upper surface, a raised ferromagnetic lug formed upon the upper surface, and a conductive shaft formed upon the lower surface of said flange, the shaft extending downward through said body;

(e) a rivet extending through the aperture formed in said bottom plate and through the aperture formed in said elastic strip, said rivet being attached to the shaft o said flange;

(f) a magnetic connection member having a substantially planar lower surface and a recess formed within the lower surface such that said connection member may couple with said flange, said lug being received within said recess;

(g) a conductive ground cord attached at one end to said connection member;

(h) wherein said magnetic connection member releasably attaches said ground cord to said flange and provides electrical conduction therebetween; and

(i) wherein said bottom plate, said rivet, said shaft, and said flange cooperate to provide electrical conduction from said elastic strap and from the wearer'"'"'s skin to said magnetic connection member, and also cooperate to attach themselves and said body and the first end of said elastic strap together.

2. The antistatic body band and ground cord assembly as recited in claim 1 wherein the second end of said strap is adjustably attached to said body.

3. The antistatic body band and ground cord assembly as recited in claim 2 further comprising a clasp member disposed upon said body for adjustably attaching the second end of said strap to said body.

4. The antistatic body band and around cord assembly as recited in claim 3 wherein said bottom plate further comprises two unturned lip members, said lip members providing a tight fit between said bottom plate and the recess formed within said body to prevent rotation of said bottom plate.

5. The antistatic body band and ground cord assembly as recited in claim 4 wherein said bottom plate further comprises a recess formed to receive said rivet such that no part of said rivet extends beyond the lower surface of said bottom plate, the upper surface of said recess contacting the first end of said strap.
