Abstract

Portable power supply carrier comprises an internally wired belt to be worn around a user'"'"'s waist, the belt having pairs of electrical connectors spaced along its length for operatively engaging a plurality of battery holders which are removably supported on the belt. In its simplest form, the power supply carrier uses conventional batteries to provide a single preselected DC voltage through the belt'"'"'s wiring to a power output jack; other more complex forms of the carrier may include a converter to supply a choice of DC and AC voltages either to multiple power outlets or to a voltage selector switch controlling a single output jack. An input terminal for reenergizing rechargeable batteries while connected to the power belt carrier also may be included.

Claims

1. Portable power supply carrier for use in energizing electrically operated appliances and instruments, which comprises:

a belt to be worn around a user'"'"'s waist, said belt having electrical conduit means incorporated therein, said electrical conduit means being insulated by said belt;

securing means attached to and for maintaining said belt removably in place on the user;

a plurality of electrical connector-fasteners externally mounted in pairs at spaced intervals along the length of said belt, said connector-fasteners being electrically connected to said electrical conduit means;

a plurality of electrical batteries for providing power to the portable power supply carrier;

a plurality of battery holders to be mounted removably on said belt for carrying said electrical batteries and connecting said batteries electrically to said electrical conduit means;

complementary mating fastening means externally mounted in pairs on said battery holders, said fastening means being electrically connected to said batteries held in said battery holders, said fastening means being capable of mechanical and electrical attachment each to a corresponding mating one of said electrical connector-fasteners on said belt; and

output terminal means mounted on said belt for operative power-transferring attachment to the electrically operated appliance to be energized and operated, said output terminal means being electrically connected to said electrical conduit means whereby said electrical connector-fasteners are electrically interconnected with said output terminal means so that current from said electrical batteries held in said battery holders is transmitted through said electrical conduit means and carried to said output terminal means for energizing the electrical appliance attached thereto.

2. Portable power supply carrier as defined in claim 1, wherein said belt is of laminated construction and insulatingly carries said electrical conduit means distributed between the layers of said belt.

3. Portable power supply carrier as defined in claim 1, wherein each of said battery holders is capable of carrying a pair of said batteries and of electrically connecting said pair of said batteries in series to form a single power unit source.

4. Portable power supply carrier as defined in claim 3, wherein said electrical batteries each has a strength of 1.5 volts.

5. Portable power supply carrier as defined in claim 3, wherein each of said battery holders comprises:

a housing;

a pair of electrical battery contacts mounted on the inner surface of the bottom wall of said housing;

a cover member fitting on and enclosing said housing;

a spring battery contact mounted on the inner surface of the top wall of said cover member, said spring contact being capable of holding of said electrical batteries in said battery holder in series connected engagement; and

electric wiring contained within said battery holder housing and connecting each of said pair of electrical contacts to one of said complementary mating fastening means.

6. Portable power supply carrier as defined in claim 1, wherein each of said battery holders has a pair of said complementary mating fastening means mounted on its back wall, and each of said battery holders has spacing ribs projecting rearwardly from said back wall for positioning said belt with respect to said battery holder.

7. Portable power supply carrier as defined in claim 6, further comprising a plurality of loop-forming flaps, at least one end of each of said flaps being mounted removably on said back wall of each of said battery holders, said belt being held firmly against said spacing ribs of said battery holders by said flaps overlying said belt so that said electrical connectors, mechanically and electrically joined with said complementary mating fastening means, are covered and protected by said flaps.

8. Portable power supply carrier as defined in claim 4, wherein said electrical conduit means is so arranged that said single power units mounted in said battery holders on said belt are connected in parallel to provide a DC voltage of 3 volts to said output terminal means.

9. Portable power supply carried as defined in claim 4, wherein said electrical conduit means is so arranged that said single power units mounted in said battery holders on said belt are connected partially in parallel and partially in series to produce a DC voltage of 6 volts at said output terminal means.

10. Portable power supply carrier as defined in claim 4, wherein said electrical conduit means is so arranged that said single power units mounted in said battery holders on said belt are connected in series to provide a DC voltage of 9 volts to said output terminal means.

11. Portable power supply carrier as defined in claim 1, wherein said electrical conduit means is so arranged that said electrical batteries are connected both in series and in parallel to make selectively available direct currents of more that one voltage to said output terminal means.

12. Portable power supply carrier as defined in claim 1, further comprising:

an electrical current converter; and

a pair of said complementary mating fastening means externally mounted on said converter for attachment each to a corresponding one of said electrical connector fasteners on said belt, said electrical conduit means being arranged to connect said battery holders to said converter and said converter to said output terminal means, so that alternating current is provided at said terminal means.

13. Portable power supply carrier as defined in claim 12, wherein said converter has the capacity not only to convert direct current from said batteries into alternating current, but also to reconvert said alternating current back to a direct current of selected voltage and to supply both said alternating and said direct currents selectively to said output terminal means.

14. Portable power supply carrier as defined in claim 12, further comprising said electrical conduit means being so arranged that said electrical batteries are connected both in series and in parallel to make direct current of more than one voltage as well as alternating current selectively available at said output terminal means.

15. Portable power supply carrier as defined in claim 1, wherein said output terminal means comprises a plurality of output jacks, each of said output jacks being connected to said electrical batteries through said electrical conduit means so as to make available a different voltage at each of said output jacks.

16. Portable power supply carrier as defined in claim 1, wherein said output terminal means comprises:

a single output jack; and

a voltage selector switch, connected by said electrical conduit means so that said selector switch can be set to apply selectively a desired voltage current to said single output jack.

17. Portable power supply carrier as defined in claim 1, further comprising input recharging terminal means connected through said electrical conduit means to said battery holders to reenergize said electrical batteries held in said battery holders, said electrical batteries being of the rechargeable type.

18. Portable power supply carrier as defined in claim 1, further comprising an electrical connecting cord capable of electrically linking said output terminal means to an electrical appliance being energized.

19. Portable power supply carrier as defined in claim 17, further comprising a recharging connecting cord capable of electrically linking said input recharging terminal means to a conventional electrical wall outlet.
