Abstract

A battery charger includes telephone handset and a connector for connecting with a cellular phone. A sound signal can be transmitted between the telephone handset and the cellular phone via the connector.

Claims

1. A battery charger comprising:

a charger section capable of charging a battery of a power tool;

a connector connectible with a cellular phone;

a speaker section converting a sound signal received from the cellular phone via the connector into a sound,

a microphone section converting a sound into a sound signal that can be transmitted to the cellular phone; and

a holder capable of being held by a user and supporting the speaker section and the microphone section, so that the user can use the speaker section and the microphone section for making a call through use of a telecommunication function of the cellular phone.

2. The battery charger as in claim 1, further comprising a housing having the charger section assembled therewith.

3. The battery charger as in claim 2, further comprising a fixed phone section assembled with the housing and configured to enable a call through use of the telecommunication function of the cellular phone;

wherein the fixed phone section includes a telephone handset; and

wherein the telephone handset comprises the holder, the first speaker section and the microphones section.

4. The battery charger as in claim 1, further comprising a revolving light capable of revolving and emitting light according to a charging condition of the battery.

5. The battery charger as in claim 1, further comprising a revolving light capable of revolving and emitting light when the cellular phone receives a call.

6. The battery charger as in claim 1, further comprising a power supply section capable of supplying a power of the battery of the power tool to the cellular phone.

7. The battery charger as in claim 1, further comprising a power supply section capable of supplying a power from a commercially available power source to the cellular phone.

8. The battery charger as in claim 2, further comprising a speaker capable of converting a sound signal transmitted from the cellular phone into a sound, wherein the speaker is disposed within the housing.

9. The battery charger as in claim 2, further comprising an electrical outlet mounted to the housing and capable of supplying an AC power.

10. The battery charger as in claim 2, wherein the housing has opposite end portions covered by elastic members, respectively.

11. A battery charger comprising:

a charger section for charging a battery of a power tool;

a connector connectible with a cellular phone;

a telephone set including a microphone portion and a speaker portion; and

a control section;

wherein the connector and the telephone set are electrically connected to the control section, so that a sound signal can be transmitted between the telephone set and the cellular phone via the control section.

12. The battery charger as in claim 11, wherein the charger section is electrically connected to the control section.

13. The battery charger as in claim 11, further comprising a revolving light electrically connected to the control section, so that the revolving light revolves and emits light when a charging operation of the battery has been completed.

14. The battery charger as in claim 11, further comprising a revolving light electrically connected to the control section, so that the revolving light revolves and emits light when the cellular phone has received a call.

15. The battery charger as in claim 11, further comprising a power supply section electrically connected to the control section and capable of supplying a DC power of the battery of the power tool to the cellular phone.

16. The battery charger as in claim 11, further comprising a speaker electrically connected the control section and capable of receiving a sound signal from the cellular phone and converting the sound signal into a sound.

17. The battery charger as in claim 15, wherein the power supply section can receive a supply of AC power from a commercially available AC power source, and wherein an electrical outlet is connected to the power supply section, so that an electric device can be connected to the electrical outlet.

18. A battery charger comprising:

a charger section for charging a battery of a power tool;

a connector connectible with a cellular phone;

a telephone handset;

a control section connected between the connector and the telephone handset, so that a sound signal can be transmitted between the telephone handset and the cellular phone via the connector.

19. The battery charger as in claim 18, further comprising a housing, wherein the charger section and the control device are assembled with the housing, and the connector is mounted to the housing.

20. The battery charger as in claim 19, further comprising a fixed phone section mounted to the housing, wherein the telephone handset is connected to the stationary phone section via a cable.
