Abstract
Abstract A device for grounding static electricity from a person comprising a case and connected band to be worn on the limb of the person. The device includes an electrically conductive inner surface and an electrically insulative outer surface. A releasably securable connector is provided between a ground connection and the conductive inner surface of the device. A resistor is connected between the connector and the inner surface of the device and is located within the case.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
276 words
A device for draining static electricity from a person to ground while preventing a shock hazard by contact of said device with a high voltage/current carrying conductor and comprising a case, connector means and band means secured to said case, said case including an inner portion and an outer portion, said outer portion having an outer surface and said inner portion being electrically conductive and arranged for electrical contact with a portion of the body of said person, said band means being arranged for encircling a portion of the body of a person and comprising an inner and outer surface, said inner surface of said band being arranged for direct contact with said body portion of said person, said case including electrical resistance means located therein, said connector means comprising a first connector element and a second connector element, each of said connector elements being electrically conductive, said second connector element arranged to be grounded, said first connector element being mounted on said case, said second connector element being arranged for releasable securement and electrical contact with said first connector element, said resistance means being electrically interconnected between said first connector element and said electrically conductive inner portion of said case, said outer surface of said band and said outer surface of said case being electrically insulative, both of said outer surfaces being out of electrical and direct physical contact with the inner surface of said band, said conductive inner portion of said case and said body portion, whereupon when said device is in position encircling said body portion the insulative outer surfaces deter electrical contact by said high voltage/current carrying conductor with said body portion.
Claim 2
Independent Claim
276 words
A device for draining static electricity from a person to ground while preventing a shock hazard by contact of said device with a high voltage/current carrying conductor and comprising a case, connector means and band means secured to said case, said case including an inner portion and an outer portion, said outer portion having an outer surface and said inner portion being electrically conductive and arranged for electrical contact with a portion of the body of said person, said band means being arranged for encircling a portion of the body of a person and comprising an inner and outer surface, said inner surface of said band being arranged for direct contact with said body portion of said person, said case including electrical resistance means located therein, said connector means comprising a first connector element and a second connector element, each of said connector elements being electrically conductive, said second connector element arranged to be grounded, said first connector element being mounted on said case, said second connector element being arranged for releasable securement and electrical contact with said first connector element, said resistance means being electrically interconnected between said first connector element and said electrically conductive inner portion of said case, said outer surface of said band and said outer surface of said case being electrically insulative, both of said outer surfaces being out of electrical and direct physical contact with the inner surface of said band, said conductive inner portion of said case and said body portion, whereupon when said device is in position encircling said body portion the insulative outer surfaces deter electrical contact by said high voltage/current carrying conductor with said body portion.
Claim 3
Dependent Claim

Claim 5
Dependent Claim
10 words
The device of claim 1 wherein said band is expandable.
Claim 6
Dependent Claim
12 words
The device of claim 4 wherein said band comprises plural interconnected links.
