Abstract
Abstract A control apparatus for a battery pack having two power receptacles coupled to an electric circuit that includes a switch for selectively delivering power to the receptacles. The control apparatus includes (1) a structure for retaining the receptacles a predetermined distance apart; (2) a cover moveable on the retaining structure so as to selectively expose a selected one of the receptacles while simultaneously covering the nonselected one; and (3) a protuberance coupled to the cover for engaging the switch and translating movement of the cover into operable movement of the switch.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
101 words
A control apparatus for rendering operable a selected one of two power receptacles, the receptacles being coupled to an electric circuit that includes a switch for selectively delivering power to the receptacles, comprising: means for retaining the receptacles a predetermined distance apart; a cover moveable on said retaining means along a line intersecting both of said power receptacles so as to selectively expose the selected one of the two power receptacles while simultaneously covering the nonselected one of the receptacles; and means, coupling said cover to the switch, for translating the movement of said cover into operable movement of the switch.
Claim 2
Dependent Claim
101 words
A control apparatus for rendering operable a selected one of two power receptacles, the receptacles being coupled to an electric circuit that includes a switch for selectively delivering power to the receptacles, comprising: means for retaining the receptacles a predetermined distance apart; a cover moveable on said retaining means along a line intersecting both of said power receptacles so as to selectively expose the selected one of the two power receptacles while simultaneously covering the nonselected one of the receptacles; and means, coupling said cover to the switch, for translating the movement of said cover into operable movement of the switch.
Claim 3
Dependent Claim
38 words
The control apparatus recited in claim 1, wherein said power receptacles, electric circuit and switch comprise components of a battery pack, and said retaining means comprise a casing for said battery pack to which said receptacles are coupled.
Claim 4
Dependent Claim
36 words
The control apparatus recited in claim 2, wherein said battery pack casing includes a raceway and said cover has edges fitted into said raceway for providing slideable movement of said cover relative to said power receptacles.
Claim 5
Dependent Claim
17 words
The control apparatus recited in claim 1, wherein said cover is slideably moveable on said retaining means.
Claim 6
Dependent Claim
27 words
The control apparatus recited in claim 1, wherein said translating means comprises a protuberance on said cover arranged to engage said switch during movement of said cover.
Claim 7
Dependent Claim
16 words
The control apparatus recited in claim 5, wherein said protuberance is integrally formed with said cover.
Claim 8
Dependent Claim
110 words
A battery pack for delivering different output levels to at least two power receptacles, including a plurality of batteries and an electric circuit having a switch for controlling delivery of power from the batteries to the receptacles, the battery pack further comprising: means for retaining the receptacles a predetermined distance apart; a cover moveable on said retaining means along a line intersecting both of said power receptacles so as to selectively expose a selected one of the two power receptacles while simultaneously covering the nonselected one of the receptacles; and means, coupling said cover to the switch, for translating the movement of said cover into operable movement of the switch.
Claim 9
Dependent Claim
110 words
A battery pack for delivering different output levels to at least two power receptacles, including a plurality of batteries and an electric circuit having a switch for controlling delivery of power from the batteries to the receptacles, the battery pack further comprising: means for retaining the receptacles a predetermined distance apart; a cover moveable on said retaining means along a line intersecting both of said power receptacles so as to selectively expose a selected one of the two power receptacles while simultaneously covering the nonselected one of the receptacles; and means, coupling said cover to the switch, for translating the movement of said cover into operable movement of the switch.
Claim 10
Dependent Claim
21 words
The battery pack recited in claim 7, wherein said coupling means permits sliding movement of said cover relative to the receptacles.
