CROSS-REFERENCE TO RELATED APPLICATIONS

This Application claims the benefit of U.S. Provisional Application 61/487,051 filed on May 17, 2011, and U.S. application Ser. No. 13/228,151, filed on Sep. 8, 2011, the disclosures of which are incorporated by reference herein in its entirety.

FIELD OF THE INVENTION

The invention relates to a device worn on the wrist of a user operable to store energy for later use with an electrical device such as a cellular phone.

BACKGROUND OF THE INVENTION

The use of energy to charge a cellular phone is currently known and used. For instance, a docking station is operable to connect the cellular phone so as to charge the cellular phone. However, such docking stations require the user to remain adjacent a power source. Portable power sources are also known, however such portable devices must be carried in a user's pocket, purse, or back pack. Accordingly, it remains desirable to have a device which may be worn as part of the user's outfit and is conveniently located so as to allow the user to operate a cellular phone while charging the cellular phone simultaneously while on the go.

SUMMARY OF THE INVENTION

According to one aspect of the invention, a band and a battery for storing power is provided. The band is adapted to be worn around a wrist of a user. The band includes a storage space configured for holding electrical components operable to store and discharge electrical power, and a cover to enclose the storage space. The device includes a battery adapted to store and discharge electrical power. The device may further include an electrical circuit operable to control the charge and discharge of electricity to and from the battery.
The storage space may further contain an electrical chord and a mechanism operable to retract the electrical chord. The electrical chord may include an end portion adapted to engage power input of an electrical device, such as a cellular phone.
The device may further include an electrical energy generating mechanism operable to transform movement into electrical energy, such as an auxiliary device. Specifically, the auxiliary device converts the swaying of a user's arm into electricity. The auxiliary device may also be wired to the battery so as to charge the battery.
The band includes a first surface and a second surface. The first surface of the band is covered by the cover, and the second surface of the band is exposed to the wrist of a user when worn. The storage space is disposed between the first and second surfaces. The storage space may including mounting portions operable to hold various electrical components such as the battery, the electrical circuit, the electrical chord, and a mechanism for retracting the electrical chord.
In a second preferred embodiment, the band includes a base portion, and the cover is adapted to be disposed over the base portion. The cover includes a display. The base portion is configured to house electrical components operable to tell time. The time is shown on the display.

The electrical circuit 26 may also control the charging and discharging of the electrical power stored in the battery 20. The battery 20 may be a rechargeable battery 20 such as a lithium ion battery 20 or any other battery 20 currently known and used in the art for storing electrical power.
The device 10 may use a plurality of covers 14, each cover 14 may be decorated with design and/or indicia indicated by reference number 28. The covers 14 may be removed from the band 16 so as to allow the user to change covers 14 according to the user's choice. In one embodiment, the device 10 may include a fastening device 30 operable to secure the cover 14 with respect to the band 16. Specifically, the fastening device 30 is a male member 32 formed of an electric conducting material. The fastening device 30 is operable to engage a female member 34 so as to provide electrical connection the battery 20 and the output 22.
The band 16 includes a first surface 36 a and a second surface 36 b. The first surface 36 a of the band 16 is covered by the cover 14, and the second surface 36 b of the band 16 is exposed to the wrist of a user when worn. The storage space 18 is disposed between the first and second surfaces 36 a, 36 b. The storage space 18 may include mounting portions 38 to hold various electrical components such as the battery 20, and the electric circuit.
With reference now to FIG. 2, the storage space 18 may further house the output 22. The output 22 may be exposed on the second surface 36 b of the band 16. The second surface 36 b of the band 16 includes a detent 40 so as to keep the output 22 behind the second surface 36 b of the band 16 with respect to the user's wrist. The output 22 is an adapter 42 electrically connected to the battery 20. Thus, a user may mount a micro-USB chord or the like to the adapter 42 so as to charge the electrical device 12. The output 22 may be configured to receiving electrical power from a power source so as to charge the batter 20 and to supply power to an electrical device such as a mobile phone 12.
It should be appreciated that the cover 14 may be adapted to mount onto the band 16 in other ways. With reference now to FIG. 3, the cover 14 includes a hinge. A fastener is mounted onto the hinge and exposed to the first surface 36 a of the band 16. The output 22 may be disposed within the inner surface wall of the band 16. The output 22 is configured to receive an connection so as to provide power to charge the batter 20. The output 22 may be further configured to connect to an electrical device 12 so as to supply power to the electrical device 12.
