Abstract
Abstract A one-piece top closure for a battery enclosure such as a lantern battery is described including a substantially planar top surface in which is integrally mounted a recharge jack, and a spacer surface which extends normally to the top surface adapted to bear against the rechargeable electrochemical cells contained within the enclosure, so as to immobilize the cells. In another aspect, an improved recharge jack is described.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
140 words
In a battery enclosure having a substantially polygonal cross-section cup-shaped container, a top closure bridging the opening of the container, a battery having first and second terminals and comprising at least one rechargeable electrochemical cell disposed within the container, output terminals mounted exteriorly on the top closure and electrically connected respectively to said first and second terminals, and a recharge jack mounted in said top closure and having contacts electrically connected to said first and second terminals, an improved one-piece top closure in combination therewith comprising: a substantially planar top surface on which is integrally mounted said recharge jack and output terminals, and having ledge portions adapted to fixedly mount to said container; and a spacer integral with and extending substantially perpendicularly of said top surface and disposed inside said container bearing against the battery thereby substantially immobilizing the battery.
Claim 2
Dependent Claim
140 words
In a battery enclosure having a substantially polygonal cross-section cup-shaped container, a top closure bridging the opening of the container, a battery having first and second terminals and comprising at least one rechargeable electrochemical cell disposed within the container, output terminals mounted exteriorly on the top closure and electrically connected respectively to said first and second terminals, and a recharge jack mounted in said top closure and having contacts electrically connected to said first and second terminals, an improved one-piece top closure in combination therewith comprising: a substantially planar top surface on which is integrally mounted said recharge jack and output terminals, and having ledge portions adapted to fixedly mount to said container; and a spacer integral with and extending substantially perpendicularly of said top surface and disposed inside said container bearing against the battery thereby substantially immobilizing the battery.
Claim 3
Dependent Claim
26 words
The battery enclosure of claim 1 wherein the spacer side surface is inscribed in the polygonal container, touching its inner surface at a plurality of points.
Claim 4
Dependent Claim
20 words
The battery enclosure of claim 1 wherein the container has a substantially rectangular cross-section and the spacer is substantially cylindrical.
Claim 5
Dependent Claim
20 words
The battery enclosure of claim 3 wherein the cylindrical spacer is substantially inscribed within the rectangular container, making contact therewith.
Claim 6
Dependent Claim
20 words
The battery enclosure of claim 1 wherein the container mouth is crimped about the ledge portions of the top closure.
Claim 7
Dependent Claim
22 words
The battery enclosure of claim 1 wherein the spacer has an inwardly disposed shoulder bearing against the battery at one portion thereof.
Claim 8
Dependent Claim
156 words
In a battery enclosure adapted to receive a coaxial-type plug in an associated jack for periodic recharging of a rechargeable battery positioned in the enclosure, an improved recharge jack assembly comprising: a housing integral with an exterior surface of the enclosure and having a central axial opening for receiving the plug, the opening being defined by a tubular seat having a side slot therein; a conductive post connected to the housing and extending from the bottom of said seat axially into the opening serving as a first contact for the jack; spring contact means having a first portion disposed in said opening serving as a second contact for the jack and resiliently movable to make conductive contact with the outside of said coaxial-type plug, and a second portion connected through said side slot to said first portion and mounted on said enclosure exteriorly of said housing and electrically connected to an output terminal of the battery.
Claim 9
Dependent Claim
156 words
In a battery enclosure adapted to receive a coaxial-type plug in an associated jack for periodic recharging of a rechargeable battery positioned in the enclosure, an improved recharge jack assembly comprising: a housing integral with an exterior surface of the enclosure and having a central axial opening for receiving the plug, the opening being defined by a tubular seat having a side slot therein; a conductive post connected to the housing and extending from the bottom of said seat axially into the opening serving as a first contact for the jack; spring contact means having a first portion disposed in said opening serving as a second contact for the jack and resiliently movable to make conductive contact with the outside of said coaxial-type plug, and a second portion connected through said side slot to said first portion and mounted on said enclosure exteriorly of said housing and electrically connected to an output terminal of the battery.
Claim 10
Dependent Claim
45 words
The battery enclosure of claim 7 wherein said seat includes a downwardly protruding slotted cylinder integral with the exterior surface of the enclosure and a separate sleeve to which is affixed said conductive post, embracing and securedly attached to the outer surface of said cylinder.
Claim 11
Dependent Claim
20 words
The battery enclosure of claim 8 wherein said cylinder and sleeve have resiliently interlocking shoulder surfaces precluding detachment in use.
Claim 12
Dependent Claim
31 words
The battery enclosure of claim 7 wherein said seat is formed of a unitary assembly comprising a downwardly protruding slotted cylinder in the end of which is embedded the conductive post.
Claim 13
Dependent Claim
28 words
The battery enclosure of claim 7 wherein the spring contact means comprises a substantially flat metal spring having a generally U-shaped free end serving as the first portion.
Claim 14
Dependent Claim
34 words
The battery enclosure of claim 11 wherein intermediate the first and second portions of the spring contact means is an aperture which registers with a protrusion formed in the enclosure to maintain alignment therewith.
