Abstract
Abstract A static shock eliminator adapted for use in attachment to a conductive grounding object such as a metallic door knob, handle or key cylinder, which comprises a high resistance plate arranged adjacent the conductive grounding object and engaged at a portion thereof with the same. The high resistance plate has a first surface to be brought into contact with a person at a portion spaced from the conductive grounding object in a predetermined distance and a second surface to be adhered to a surface of a member on which the conductive grounding object is mounted.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
123 words
A static shock eliminator adapted for use in attachment to a conductive grounding object such as a metallic door knob, handle or key cylinder, comprising a high resistance plate formed in a rectangular shape to be engaged at one end portion thereof with said conductive grounding object, said high resistance plate having a first surface to be brought into contact with a person and a second surface to be adhered to a surface of a member on which said conductive grounding object is mounted, and an insulation layer integrally formed on said first surface of said high resistance plate in such a manner that said first surface is exposed only at a portion spaced from said conductive grounding object at a predetermined distance.
Claim 2
Dependent Claim
123 words
A static shock eliminator adapted for use in attachment to a conductive grounding object such as a metallic door knob, handle or key cylinder, comprising a high resistance plate formed in a rectangular shape to be engaged at one end portion thereof with said conductive grounding object, said high resistance plate having a first surface to be brought into contact with a person and a second surface to be adhered to a surface of a member on which said conductive grounding object is mounted, and an insulation layer integrally formed on said first surface of said high resistance plate in such a manner that said first surface is exposed only at a portion spaced from said conductive grounding object at a predetermined distance.
Claim 3
Dependent Claim
37 words
A static shock eliminator as claimed in claim 1, further comprising a metallic spring element contained within the second surface of said high resistance plate to be engaged at one end thereof with said conductive grounding object.
Claim 4
Dependent Claim
59 words
A static shock eliminator as claimed in claim 2, further comprising a tape adhered at one surface thereof to the second surface of said high resistance plate to retain said spring element in place and coated at another surface thereof with adhesive to be attached to the surface of the member on which said conductive grounding object is mounted.
Claim 5
Dependent Claim
39 words
A static shock eliminator as claimed in claim 1, wherein said high resistance plate is formed at one end portion thereof with a recess for engagement with the head portion of a key cylinder mounted in an automobile door.
Claim 6
Dependent Claim
51 words
A static shock eliminator as claimed in claim 1, further comprising a tape having a first surface adhered to the second surface of said high resistance plate and a second surface coated with adhesive to be attached to the surface of the member on which said conductive grounding object is mounted.
