Abstract
A lamp rechargeable dry cell power pack and recharging device therefor is disclosed. The recharging device comprises a socket for receiving the power pack, a plurality of electrodes are presented in the socket and arranged to contact corresponding electrodes on the power pack when it is fully inserted in the socket. The power pack is irregular shaped in cross-section and the socket is correspondingly shaped to receive and support the power pack in only one orientation of the power pack relative to the socket to ensure the registration of the plurality of socket electrodes with corresponding power pack electrodes.
Claims23
In combination, a rechargeable dry cell power pack with a lamp and recharging device for said dry cell power packs, said recharging device comprising a socket for receiving at least a lower portion of said power pack, a plurality of electrodes being presented in said socket and so arranged to contact corresponding electrodes on said power pack when fully inserted in said socket, said lamp being electrically connected to said power pack by a length of electrical wiring, means provided on said recharger device for holding said lamp accompanying said power pack while said power pack is in place in the socket of said recharger, said power pack being curved slightly to conform to a user's hip when in use, said power pack electrodes being positioned in an inner face portion of said power pack so as to be adjacent a user's hip when in use, said socket having a corresponding shape to receive at least said lower portion of said power pack, said socket having correspondingly curved opposing first and second faces, said socket electrodes being positioned on said first face so as to contact said power pack electrodes when said power pack is inserted into said socket, said socket receiving and supporting said power pack in only one orientation of said power pack relative to said socket to ensure that said plurality of socket electrodes contact said corresponding power pack electrodes.
A recharging device for a lamp rechargeable dry cell power pack comprising a body portion having a cavity for receiving bottom first at least a lower portion of a lamp dry cell power pack which is irregular-shaped in cross-section, said cavity being shaped to receive and cooperate with the lower portion of a lamp power pack to support same, said body portion having means for mounting said recharging device on a wall panel in a manner that said cavity in cross-section extends generally in a vertical plane, said cavity having a plurality of electrodes so arranged to contact corresponding electrodes external of a lamp dry cell power pack when inserted in said cavity, said body portion is molded from a plastic material, said cavity being formed with an opening in its lowermost portion when mounted on a wall panel to permit pushing of debris out of said cavity through said opening when a lamp power pack is inserted into said cavity.
In combination, a rechargeable dry cell power pack with a lamp and recharging device for said dry cell power pack, said recharging device comprising a body portion having a socket for receiving bottom first at least a lower portion of said dry cell power pack which is irregular-shaped in cross-section, said socket being shaped to receive and cooperate with the lower portion of a lamp power pack to support same, said body portion having means for mounting said recharging device on a wall panel in a manner that said cavity in cross-section extends generally in a vertical plane, said cavity having a plurality of electrodes so arranged to contact corresponding electrodes external of said dry cell power pack when inserted in said socket, said body portion is molded from a plastic material, said socket being formed with an opening in its lowermost portion when mounted on a wall panel to permit pushing of debris out of said socket through said opening when said dry cell power pack is inserted into said socket, said socket receiving and supporting said dry cell power pack in only one orientation of said power pack relative to said socket to ensure that said plurality of socket electrodes contact said corresponding power pack electrodes.
