Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
211 words
A battery enclosure apparatus comprising: wall means; a top comprising first and second top portions positionable on the wall means to form a battery enclosure; a plurality of tabs extending from each top portion; means defining a plurality of recesses associated with the wall means, each tab being positionable in a recess with the top portions positioned on the wall means to form a battery enclosure, to prevent lifting of the top portions from the wall means; each top portion being movable laterally of the wall means to move the tabs thereof to positions relative to the wall means wherein each top portion may be lifted from the wall means; means for selectively securing the first top portion together with the second top portion in position on the wall means to form a battery enclosure; and first additional tab means secured relative to the wall means and extending toward the top, and second additional tab means secured to at least one of the first and second top portions and positioned relative to the first additional tab means, with the top portion in position on the wall means, to limit movement of the one top portion in a sideward direction relative to the lateral movement thereof allowing lifting of that top portion.
Claim 2
Dependent Claim
211 words
A battery enclosure apparatus comprising: wall means; a top comprising first and second top portions positionable on the wall means to form a battery enclosure; a plurality of tabs extending from each top portion; means defining a plurality of recesses associated with the wall means, each tab being positionable in a recess with the top portions positioned on the wall means to form a battery enclosure, to prevent lifting of the top portions from the wall means; each top portion being movable laterally of the wall means to move the tabs thereof to positions relative to the wall means wherein each top portion may be lifted from the wall means; means for selectively securing the first top portion together with the second top portion in position on the wall means to form a battery enclosure; and first additional tab means secured relative to the wall means and extending toward the top, and second additional tab means secured to at least one of the first and second top portions and positioned relative to the first additional tab means, with the top portion in position on the wall means, to limit movement of the one top portion in a sideward direction relative to the lateral movement thereof allowing lifting of that top portion.
Claim 3
Dependent Claim
55 words
The apparatus of claim 1 and further comprising bracket means secured relative to a top portion and positioned relative to the wall means, with that top portion positioned on the wall means, to limit movement of that top portion in a sideward direction relative to the lateral movement thereof allowing lifting of that top portion.
Claim 4
Dependent Claim
40 words
The apparatus of claim 2 wherein the first additional tab means comprise a single bar fixed relative to the wall means, and wherein the second additional tab means comprise a plurality of individual bars secured relative to that top portion.
Claim 5
Dependent Claim
159 words
A battery enclosure apparatus comprising: stationary wall means for rigidly walling a battery when placed therein, the wall means defining a first pair of opposed walls secured to a second pair of opposed walls; a top comprising first and second top portions normally positioned on the wall means to form a battery enclosure; a plurality of tabs extending from the top portions, the tabs extending toward the first pair of walls when the top portions are normally positioned; means defining a plurality of recesses on the first pair of walls, each recess for receiving a respective tab when the top portions are normally positioned to prevent lifting of the top portions from the wall means, each top portion being movable laterally with respect to the second pair of walls wherein each top portion may be lifted from the wall means; and means for selectively securing the first top portion with the second top portion to form a battery enclosure.
Claim 6
Dependent Claim
159 words
A battery enclosure apparatus comprising: stationary wall means for rigidly walling a battery when placed therein, the wall means defining a first pair of opposed walls secured to a second pair of opposed walls; a top comprising first and second top portions normally positioned on the wall means to form a battery enclosure; a plurality of tabs extending from the top portions, the tabs extending toward the first pair of walls when the top portions are normally positioned; means defining a plurality of recesses on the first pair of walls, each recess for receiving a respective tab when the top portions are normally positioned to prevent lifting of the top portions from the wall means, each top portion being movable laterally with respect to the second pair of walls wherein each top portion may be lifted from the wall means; and means for selectively securing the first top portion with the second top portion to form a battery enclosure.
Claim 7
Dependent Claim
45 words
The apparatus of claim 4 wherein each top portion defines downwardly extending flange means exterior the wall means, the flange means partially surrounding the upper portion of the wall means for limiting lateral movement of the top portions when the top portions are selectively secured.
Claim 8
Dependent Claim
14 words
The apparatus of claim 4 wherein the selective securing means comprises releasable latch means.
Claim 9
Dependent Claim
41 words
The apparatus of claim 4 further comprising bracket means secured to the top portions and extending downward exterior the wall means for limiting sideward movement of the top portions with respect to the lateral movement which allows lifting the top portions.
Claim 10
Dependent Claim
37 words
The apparatus of claim 4 further comprising a gutter member positioned under the area where the top portions are adjacent each other when normally positioned, the gutter member spanning the distance between the first pair of walls.
