Abstract

A power tool battery pack enclosure is configured to be retrofittedly coupled to battery pack receptacles of a plurality of power tools, each battery pack receptacle configured to removably receive a plurality of power tool battery packs. The enclosure includes a first clamshell member and a second clamshell member configured to be coupled around at least a portion of an exterior surface of each battery pack receptacle. Each of the first and second clamshell members have a top wall portion configured to be received over the exterior surface of the battery pack receptacle and a sidewall portion that extends downward from the top wall portion over at least a portion of the battery pack housing when the battery pack is received in the battery pack receptacle. The first and second enclosure members cover at least a portion of the battery back receptacle and at least a portion of the portion of a battery pack housing while allowing the battery pack to be removed from the battery pack receptacle while the enclosure remains coupled to the battery pack receptacle.

First claim

What is claimed is:

1. A power tool system comprising:
a power tool including a tool housing, a motor received in the tool housing, an output member driven by the motor and configured to perform an operation on a workpiece, and a battery pack receptacle coupled to the tool housing, the battery pack receptacle including a first mechanical and electrical interface; a battery pack configured to be removably coupled to the power tool, the battery pack including a battery pack housing and a second mechanical and electrical interface configured to be mechanically and electrically coupled with the first mechanical and electrical interface of the battery pack receptacle; and an enclosure having first and second enclosure members configured to be receive at least partially over the battery back receptacle and forming a non-movable enclosure coupled to each other and to the battery pack receptacle so that the first and second enclosure members cover at least a portion of the battery back receptacle and at least a portion of the battery pack housing while allowing the battery pack to be removed from the battery pack receptacle while the enclosure remains coupled to the battery pack receptacle.

2. The power tool system of claim 1 , wherein the first and second enclosure members include a first clamshell member and a second clamshell member configured to be coupled around at least a portion of an exterior surface of the battery pack receptacle.

3. The power tool system of claim 2 , wherein each of the first and second clamshell members includes a top wall portion configured to be received over the exterior surface of the battery pack receptacle and a sidewall portion that extends downward from the top wall portion over at least a portion of the battery pack housing when the battery pack is received in the battery pack receptacle.

4. The power tool system of claim 3 , wherein each of the first and second clamshell members further includes a bottom wall portion extending from the sidewall portions toward one another to cover a bottom surface of the battery pack housing when the battery pack is received in the battery pack receptacle.

5. The power tool system of claim 3 , wherein the enclosure further comprises a door coupled to the first and second clamshell members, the door configured to be openable to removably insert the battery pack into the battery pack receptacle.

6. The power tool system of claim 5 , wherein the first and second clamshell members and the door substantially completely enclose the battery pack when the battery pack is inserted into the battery pack receptacle.

7. The power tool system of claim 1 , wherein the enclosure is configured to receive a plurality of different battery pack sizes within the enclosure.

8. The power tool system of claim 1 , wherein the first and second enclosure members each include an elastomeric member configured to form a seal between the enclosure members and the battery pack receptacle.

9. The power tool system of claim 1 , wherein the first and second enclosure members are configured to be coupled to battery pack receptacle by at least one of a snap-fit connection and a threaded fastener.

10. The power tool system of claim 1 , wherein a size of the battery pack enclosure is user adjustable.

11. The power tool system of claim 1 , wherein the battery pack enclosure includes at least one accordion-style wall portion to facilitate user adjustment of the size of the enclosure.

12. The power tool system of claim 1 , wherein the enclosure is configured to be attachable to a plurality of other power tools each having a similarly configured battery pack receptacle.

13. The power tool system of claim 1 , wherein the power tool includes at least one of a light unit and a control switch coupled to the battery pack receptacle, wherein the enclosure is configured to leave the at least one of the light unit and the control switch exposed when the enclosure is coupled to the battery pack receptacle.

14. The power tool system of claim 1 , wherein the power tool comprises one of a drill, a drill/driver, an impact driver an impact wrench, a reciprocating saw, a circular saw, a grinder, a hammer drill, a nailer, an oscillating multi-tool, and a spayer.

15. The power tool system of claim 1 , wherein the first and second enclosure members are configured to be retrofitted onto an existing power tool.

16. A power tool system comprising:
a power tool including a tool housing, a motor received in the tool housing, an output member driven by the motor and configured to perform an operation on a workpiece, and a battery pack receptacle coupled to the tool housing, the battery pack receptacle including a first mechanical and electrical interface;
a battery pack configured to be removably coupled to the power tool, the battery pack including a battery pack housing and a second mechanical and electrical interface configured to be mechanically and electrically coupled with the first mechanical and electrical interface of the battery pack receptacle; and
an enclosure having a first clamshell member and a second clamshell member configured to be coupled to the battery pack receptacle around at least a portion of an exterior surface of the battery back receptacle and at least a portion of the battery pack housing, and a door coupled to the first and second clamshell members, the door configured to be openable to removably couple the battery pack to the battery pack receptacle.

17. The power tool system of claim 16 , wherein each of the first and second clamshell members includes a top wall portion configured to be received over the exterior surface of the battery pack receptacle, a sidewall portion that extends downward from the top wall portion over at least a portion of the battery pack housing when the battery pack is received in the battery pack receptacle, and a bottom wall portion extending from the sidewall portions toward one another to cover a bottom surface of the battery pack housing when the battery pack is received in the battery pack receptacle.

18. The power tool system of claim 17 , wherein the first and second clamshell members and the door substantially completely enclose the battery pack when the battery pack is inserted into the battery pack receptacle.

19. A power tool system comprising:
a power tool including a tool housing, a motor received in the tool housing, an output member driven by the motor and configured to perform an operation on a workpiece, and a battery pack receptacle coupled to the tool housing, the battery pack receptacle including a first mechanical and electrical interface;
a battery pack configured to be removably coupled to the power tool, the battery pack including a battery pack housing and a second mechanical and electrical interface configured to be mechanically and electrically coupled with the first mechanical and electrical interface of the battery pack receptacle; and
an enclosure having a top wall portion configured to be received over an exterior surface of the battery pack receptacle, a sidewall portion that extends downward from the top wall portion over at least a portion of the battery pack housing when the battery pack is received in the battery pack receptacle, a bottom wall portion extending inward from the sidewall portion to cover at least a portion of a bottom surface of the battery pack housing when the battery pack is received in the battery pack receptacle, and a door coupled to at least one of the wall portions and configured to be openable to removably couple the battery pack to the b
