Abstract

An adapter includes an insertion part that is inserted into a body of a power tool and has terminals for electrically connecting with the power tool; a pair of rails for guiding insertion of a battery pack in a direction substantially orthogonal to the insertion direction of the insertion part; an operating part constituting tool-latching device for attaching to and detaching from the body of the power tool; and a receiving part constituting battery-latching device for attaching to and detaching from the battery pack. The operating part of the tool-latching device and the receiving-side of the battery-latching device are disposed in different positions when viewing the adapter in the insertion direction of the insertion part.

Claims

1. An adapter configured for mounting a battery to a power tool, comprising:

an insertion part protruding in a first direction and insertable into a body of a power tool, the insertion part having a plurality of terminals for electrically connecting with the power tool;

a pair of rails that guides a battery pack to move in a second direction substantially orthogonal to the first direction for mounting the battery pack;

a tool-latching device for attaching to and detaching from the body of the power tool; and

a battery-latching device for attaching to and detaching from the battery pack,

wherein the tool-latching device and the battery-latching device are disposed in different positions when viewing the adapter in the first direction.

2. The adapter according to claim 1, further comprising a base part having a pair of first side walls disposed in substantially confronting relation with each other and a pair of second side walls disposed in substantially confronting relation with each other and connecting the pair of first side walls, wherein the tool-latching device comprises an operating part capable of engaging a receiving part provided in the body of the power tool, and the battery-latching device comprises a receiving part with which an operating part provided in the battery pack is engageable, the operating part of the tool-latching device being disposed on a different wall of the pair of first side walls and the pair of second side walls than the receiving part of the battery-latching device.

3. The adapter according to claim 2, wherein the operating part of the tool-latching device is disposed on at least one of the pair of second side walls, and the receiving part of the battery-latching device is formed in the pair of first side walls.

4. The adapter according to claim 2, wherein the receiving part of the battery-latching device is formed in the pair of second side walls, and the operating part of the tool-latching device is disposed on the pair of first side walls.

5. The adapter according to claim 2, wherein operation of the operating part of the tool-latching device detaches the adapter from the body of the power tool.

6. The adapter according to claim 2, wherein operation of the operating part of the battery pack detaches the adapter from the battery pack.

7. An adapter-battery pack assembly comprising an adapter and a battery pack,

wherein the adapter is configured to mount the battery pack to a power tool and comprises:

an insertion part protruding in a first direction and insertable into a body of the power tool, the insertion part having a plurality of terminals for electrically connecting with the power tool;

a pair of rails that guides a battery pack to move in a second direction substantially orthogonal to the first direction for mounting the battery pack;

a tool-latching device including an operating part for attaching the adapter to and detaching the adapter from the body of the power tool; and

a receiving part for attaching the adapter to and detaching the adapter from the battery pack,

wherein the battery pack comprises;

a battery case accommodating a battery;

a pair of rail grooves formed in the battery case for inserting the pair of rails; and

a battery-side operating part engageable with the receiving part,

wherein the operating part of the adapter and the receiving part are disposed in different positions when viewing the adapter in the first direction of the insertion part.

8. The adapter-battery pack assembly according to claim 7, wherein the adapter further comprises a base part having a pair of first side walls disposed in substantially confronting relation with each other and a pair of second side walls disposed in substantially confronting relation with each other and connecting the pair of first side walls, wherein the operating part of the adapter is capable of engaging a receiving part provided in the body of the power tool.

9. The adapter-battery pack assembly according to claim 8, wherein one operating part of the adapter is disposed on one of the pair of second side walls, and one receiving part of the adapter is formed in each of the pair of first side walls.

10. The adapter-battery pack assembly according to claim 8, wherein one receiving part of the adapter is formed in one of the pair of second side walls, and one operating part of the adapter is disposed on each of the pair of first side walls.

11. The adapter-battery pack assembly according to claim 7, wherein operation of the operating part of the adapter detaches the adapter from the body of the power tool.

12. The adapter-battery pack assembly according to claim 7, wherein operation of the operating part of the battery pack detaches the adapter from the battery pack.

13. A power tool comprising:

a motor;

a battery pack serving as a power source for the motor;

an accommodating section that opens outward;

an electric connector disposed adjacent the accommodating section; and

an adapter that is configured to mount the battery pack to a power tool and supplies power from the battery pack to the motor, the adapter comprising;

an insertion part that is inserted into the accommodating section and has a plurality of terminals for electrically connecting with the power tool;

a pair of rails that guides insertion of the battery pack in a direction substantially orthogonal to the insertion direction of the insertion part;

a tool-latching device including an operating part that attaches the insertion part in and detaching the insertion part from the accommodating section; and

a receiving part for attaching to and detaching from the battery pack,

wherein the operating part and the receiving part are disposed in different positions when viewing the adapter in the insertion direction of the insertion part.

14. The power tool according to claim 13, wherein the adapter further comprises a base part having a pair of first side walls disposed in substantially confronting relation with each other and a pair of second side walls disposed in substantially confronting relation with each other and connecting the pair of first side walls, wherein the operating part engages a receiving part provided in the body of the power tool, and the receiving part engages an operating part provided in the battery pack.

15. The power tool according to claim 14, wherein one operating part of the adapter is disposed on one of the pair of second side walls, and one receiving part of the adapter is formed in each of the pair of first side walls.

16. The power tool according to claim 14, wherein one receiving part of the adapter is formed in one of the pair of second side walls, and one operating part of the adapter is disposed on each of the pair of first side walls.

17. The power tool according to claim 13, wherein operation of the operating part of the adapter detaches the adapter from the body of the power tool.

18. The power tool according to claim 13, wherein operation of the operating part of the battery pack detaches the adapter from the battery pack.
