Abstract
Abstract An adjustable, conductive body strap utilizing a connector securing a strip of material held in a closed loop with a mechanical connector with the interior surface of the strip of material being electrically conductive. An electrical connector connects the conductive surface of the strip of material to a connection point to provide for external electrical ground connection. The mechanical connector secures one end of the strip of material in place. The connector adjustably secures the opposite end of the strip of material utilizing a recess into which a plate is mounted with a plurality of spikes. The strip of material is impaled upon the plurality of spikes. A cover, preferably hinged, then secures the strip of material over the plurality of spikes once it is suitably adjusted completing the adjustable connection. An electrically conductive back plate connects both ends of the strip of material to the electrical connection point.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
304 words
An adjustable, conductive body strap, comprising: a strip of material having a first end and a second end, said strip of material being electrically conductive on at least one surface, being elastomerically extensible in its longitudinal direction, and being of at least a length to enable said strip of material to encircle a body part; a mechanical connector receiving said first end and said second end of said strip of material to form a closed loop with said strip of material with said at least one surface toward the interior of said closed loop, said mechanical connector having a first part receiving said first end of said strip of material and having a second part receiving said second end of said strip of material said first part of said mechanical connector having a recess receiving said first end of said strip of material, said recess being formed with a plurality of spikes upon which said strip of material is impaled and secured; said second part of said mechanical connector having a plate over which said second end of said strip of material is passed, said plate having a plurality of spikes upon which said strip of material may be impaled after said strip of material has been pulled tight around said body part, said second part of said mechanical connector further having a hinged cover for being secured over said spikes of said plate trapping said strip of material thereon; a second cover secured to said first part of said mechanical connector securing said first end of said strip of material upon said spikes; and electrical connection means coupled to said strip of material for making electrical contact with said at least one conductive surface and for providing a connection point for an electrical cable capable of connecting said conductive body strap to ground.
Claim 2
Dependent Claim
304 words
An adjustable, conductive body strap, comprising: a strip of material having a first end and a second end, said strip of material being electrically conductive on at least one surface, being elastomerically extensible in its longitudinal direction, and being of at least a length to enable said strip of material to encircle a body part; a mechanical connector receiving said first end and said second end of said strip of material to form a closed loop with said strip of material with said at least one surface toward the interior of said closed loop, said mechanical connector having a first part receiving said first end of said strip of material and having a second part receiving said second end of said strip of material said first part of said mechanical connector having a recess receiving said first end of said strip of material, said recess being formed with a plurality of spikes upon which said strip of material is impaled and secured; said second part of said mechanical connector having a plate over which said second end of said strip of material is passed, said plate having a plurality of spikes upon which said strip of material may be impaled after said strip of material has been pulled tight around said body part, said second part of said mechanical connector further having a hinged cover for being secured over said spikes of said plate trapping said strip of material thereon; a second cover secured to said first part of said mechanical connector securing said first end of said strip of material upon said spikes; and electrical connection means coupled to said strip of material for making electrical contact with said at least one conductive surface and for providing a connection point for an electrical cable capable of connecting said conductive body strap to ground.
