Abstract
Abstract A universal, one-piece-molded, protective cap adapted to fit both small and large diameter battery terminal posts. The cap includes a body portion having an accordion pleated wall which is molded to tightly fit small diameter terminals but expandable to fit large diameter terminal posts. Restraining means at both ends of the body help maintain constrictive engagement of the post by the cap. Openings at both ends of the pleats permit substantially uninhibited flexure of the pleats to effect expansion of the body.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
218 words
A universal, one-piece, nonconductive, protective cap adapted to engage either small or large diameter battery terminal posts, said cap comprising: a substantially resilient, annular body comprising a corrugated wall defining a cavity for receiving a said post, said wall having a plurality of inwardly-projecting accordion pleats defining a plurality of valleys therebetween, said pleats each having a bendable ridge for engaging a said post and permitting radial expansion of said body when said cap is positioned about a said post; tensioning means on one end of said body in part defining said cavity, said means including a hub and a plurality of substantially resilient connectors extending radially from said hub, said connectors each engaging a floor of one of said valleys and defining a plurality of first openings between said connectors at the ends of said pleats at said one end of said body; and an integral, substantially resilient flange extending radially outwardly from the other end of said body, said flange having an inboard edge joined to said floors at the other end of said body so as to define a plurality of second openings at the other ends of said pleats; said first and second openings serving to permit flexure of said pleats and expansion of said body to accommodate said small or large diameter posts.
Claim 2
Dependent Claim
218 words
A universal, one-piece, nonconductive, protective cap adapted to engage either small or large diameter battery terminal posts, said cap comprising: a substantially resilient, annular body comprising a corrugated wall defining a cavity for receiving a said post, said wall having a plurality of inwardly-projecting accordion pleats defining a plurality of valleys therebetween, said pleats each having a bendable ridge for engaging a said post and permitting radial expansion of said body when said cap is positioned about a said post; tensioning means on one end of said body in part defining said cavity, said means including a hub and a plurality of substantially resilient connectors extending radially from said hub, said connectors each engaging a floor of one of said valleys and defining a plurality of first openings between said connectors at the ends of said pleats at said one end of said body; and an integral, substantially resilient flange extending radially outwardly from the other end of said body, said flange having an inboard edge joined to said floors at the other end of said body so as to define a plurality of second openings at the other ends of said pleats; said first and second openings serving to permit flexure of said pleats and expansion of said body to accommodate said small or large diameter posts.
Claim 3
Dependent Claim
21 words
A cap in accordance with claim 1 wherein said annular body comprises a hollow frustum tapered to accommodate SAE-type terminal posts.
Claim 4
Dependent Claim
25 words
A cap in accordance with claim 1 wherein said other ends of said pleats are chamfered to facilitate placement of said cap onto said terminals.
Claim 5
Dependent Claim
35 words
A cap in accordance with claim 1 wherein said ridge includes a crushable rib which substantially retains its integrity when engaging a said small diameter terminal but deforms when engaging a said large diameter terminal.
