Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
99 words
In a battery accommodating device having a chamber in which a plurality of cylindrical batteries are positioned in side-by-side relation to each other and a cover pivotally supported and arranged to close an opening portion of said chamber, the improvement comprising: (a) a lock member for locking said cover in the closed position, said lock member being provided in a space surrounded by the side walls of the cylindrical batteries when loaded in said chamber and an inside wall of said chamber; and (b) an operating member for operating said lock member from the outside of said battery chamber.
Claim 2
Dependent Claim
99 words
In a battery accommodating device having a chamber in which a plurality of cylindrical batteries are positioned in side-by-side relation to each other and a cover pivotally supported and arranged to close an opening portion of said chamber, the improvement comprising: (a) a lock member for locking said cover in the closed position, said lock member being provided in a space surrounded by the side walls of the cylindrical batteries when loaded in said chamber and an inside wall of said chamber; and (b) an operating member for operating said lock member from the outside of said battery chamber.
Claim 3
Dependent Claim
137 words
In a battery accommodating device having a chamber in which a plurality of cylindrical batteries are positioned in side-by-side relation to each other and a cover pivotally supported and arranged to close an opening portion of said chamber, the improvement comprising: (a) an electrically conductive member provided on said cover and arranged to contact with said batteries, end portions of said member being formed to a curved shape so that said cover is urged in a direction to open; (b) a lock member for locking said cover in the closed position, said lock member being provided in a space surrounded by the side walls of the cylindrical batteries when loaded in said chamber and the inside wall of said chamber; and (c) an operating member for operating said lock member from the outside of said battery chamber.
Claim 4
Dependent Claim
