Abstract
Abstract A rechargeable battery-operated flashlight system includes a housing for the flashlight, batteries and associated circuitry. A two-pronged plug is rotatably mounted in the housing for movement between two positions, the prongs projecting outwardly through an opening in the housing so that in one position they project into a recess formed by a reentrant portion of the housing and in the other position they project away from the recess. Resilient contacts connect the prongs to the rest of the circuitry, and engage in detents on the prongs in their two positions to inhibit rotation thereof. A wall bracket defines a pocket for releasably accommodating a receptacle fixture for receiving the plug prongs in their one position and for supporting the housing during recharging. In their other position, the prongs can be plugged directly into an AC wall outlet.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
66 words
In a rechargeable battery-powered device, the improvement comprising a housing for the device, a recharging plug including plural electrically conductive terminal prongs adapted to be electrically coupled to the device, and means mounting said prongs on said housing for rotation about a common axis between first and second positions, such that said prongs project externally of said housing in both the first and second positions thereof.
Claim 2
Dependent Claim
66 words
In a rechargeable battery-powered device, the improvement comprising a housing for the device, a recharging plug including plural electrically conductive terminal prongs adapted to be electrically coupled to the device, and means mounting said prongs on said housing for rotation about a common axis between first and second positions, such that said prongs project externally of said housing in both the first and second positions thereof.
Claim 3
Dependent Claim
30 words
The device of claim 1, wherein said housing has a reentrant portion defining a recess therein, said prongs projecting into said recess in one of said first and second positions.
Claim 4
Dependent Claim
118 words
In a rechargeable battery-powered device, the improvement comprising a housing for the device, a recharging plug including plural electrically conductive terminal prongs, means mounting said prongs on said housing for rotation between first and second positions, each of said prongs having an electrically conductive contact portion with two spaced-apart detent recesses therein, and a plurality of flexible electrically conductive contacts adapted to be coupled to the device and respectively resiliently urged into sliding engagement with the contact portions of said prongs for maintaining electrical contact therewith while accommodating rotational movement thereof, said contacts being engageable in said detent recesses when said prongs are in the first and second positions thereof for resiliently inhibiting rotational movement of said prongs.
Claim 5
Dependent Claim
118 words
In a rechargeable battery-powered device, the improvement comprising a housing for the device, a recharging plug including plural electrically conductive terminal prongs, means mounting said prongs on said housing for rotation between first and second positions, each of said prongs having an electrically conductive contact portion with two spaced-apart detent recesses therein, and a plurality of flexible electrically conductive contacts adapted to be coupled to the device and respectively resiliently urged into sliding engagement with the contact portions of said prongs for maintaining electrical contact therewith while accommodating rotational movement thereof, said contacts being engageable in said detent recesses when said prongs are in the first and second positions thereof for resiliently inhibiting rotational movement of said prongs.
