Abstract

A power tool assembly includes a hand-held power tool, a dust collector removably coupled to the power tool, and first and second power tool battery packs each of which is interchangeably coupled with the power tool and the dust collector for separately powering the power tool and the dust collector, respectively.

First claim

What is claimed is:

1. A power tool assembly, comprising:
a hand-held power tool;
a dust collector removably coupled to the power tool; and, wherein the dust collector further includes
a housing,
a telescoping suction pipe coupled to the housing,
an electric motor positioned in the housing,
a suction fan driven by the electric motor and operable to generate a vacuum in the suction pipe,
a dust container coupled to the housing and positioned upstream of the suction fan,
an adapter including a first portion coupled to the housing and a second portion, and
an auxiliary handle coupled to the second portion of the adapter and the power tool, the adapter and the auxiliary handle supporting the power tool, wherein the power tool is positioned adjacent the dust collector, wherein the auxiliary handle includes a cylindrical band received within an arcuate slot in the adapter and a rotatable grip for constricting and expanding the band, and wherein a neck of the power tool is clamped by the band; and

first and second power tool battery packs each of which is interchangeably coupled with the power tool and the dust collector for separately powering the power tool and the dust collector, respectively.

2. The power tool assembly of claim 1 , wherein the first and second power tool battery packs are identical.

3. The power tool assembly of claim 1 , wherein the power tool and the dust collector are coupled in a side-by-side relationship.

4. The power tool assembly of claim 1 , wherein each of the first and second battery packs includes three lithium-ion battery cells.

5. The power tool assembly of claim 1 , wherein the power tool is a rotary power tool.

6. The power tool assembly of claim 5 , wherein the rotary power tool is one of a rotary hammer and a hammer drill.

7. The power tool assembly of claim 1 , wherein the telescoping suction pipe is configured to telescope along a first axis, and wherein the second battery pack is removably coupled to the housing along a second axis oriented substantially normal to the first axis.

8. The power tool assembly of claim 7 , wherein the power tool is a rotary power tool defining a rotational axis, and wherein the first axis is substantially parallel with the rotational axis of the power tool.

9. The power tool assembly of claim 1 , wherein the housing includes a first side and an opposite second side, and wherein the first portion of the adapter is interchangeably connectable to the first and second sides of the housing to thereby support the power tool adjacent a chosen one of the first and second sides of the housing.

10. The power tool assembly of claim 9 , further comprising a suction head coupled to a distal end of the suction pipe, wherein the suction head is repositionable between first and second orientations to accommodate placement of the power tool adjacent the first and second sides of the housing, respectively.

11. The power tool assembly of claim 10 , wherein the suction head is coupled to the distal end of the suction pipe between the first and second orientations.

12. The power tool assembly of claim 11 , further comprising a detent arrangement for maintaining the suction head in at least one of the first and second orientations.

13. The power tool assembly of claim 12 , wherein the detent arrangement includes first and second detent members on the suction head, and first and second detent recesses positioned on opposite sides of the suction pipe, wherein the first detent member is received in the first detent recess to maintain the suction head in the first orientation, and wherein the second detent member is received in the second detent recess to maintain the suction head in the second orientation.

14. The power tool assembly of claim 13 , further comprising an end cap coupled to the distal end of the suction pipe between the suction pipe and the suction head, wherein the first and second recesses are both defined in the end cap.

15. The power tool assembly of claim 9 , wherein the adapter includes a fixed clamp member and an opposed, movable clamp member for clamping the adapter to one of the first and second sides of the housing.

16. The power tool assembly of claim 15 , wherein each of the first and second sides of the housing includes a first notch in which the fixed clamp member is received, and a second notch in which the movable clamp member is received.

17. The power tool assembly of claim 16 , wherein the adapter includes a cam and a follower for actuating the movable clamp member between an open position in which it is displaced from the second notch and disengaged from the housing, and a closed position in which the movable clamp member is received within the second notch and engaged with the housing.

18. The power tool assembly of claim 17 , wherein the movable clamp member is integrally formed with the follower as a single piece.

19. The power tool assembly of claim 17 , wherein the adapter includes a resilient member that biases the movable clamp member away from the fixed clamp member and toward the open position.

20. The power tool assembly of claim 1 , wherein the handle includes a shaft extending from the second portion of the adapter and a clamp member movable relative to the shaft, and wherein the power tool is clamped between the movable clamp member and the adapter.

21. The power tool assembly of claim 20 , wherein the adapter includes a fixed clamp member, and wherein the power tool is clamped between the movable clamp member and the fixed clamp member.

22. The power tool assembly of claim 21 , wherein the shaft includes a threaded portion, wherein the handle includes a grip having therein a threaded insert engaged with the threaded portion of the shaft, and wherein the movable clamp member is movable along the shaft in response to relative rotation between the grip and the shaft for clamping the power tool between the movable clamp member and the fixed clamp member.

23. The power tool assembly of claim 22 , wherein the handle includes a spacer positioned between the movable clamp member and the grip.

24. The power tool assembly of claim 1 , wherein the dust collector further includes
a switch electrically connecting the motor with the second battery to activate the motor in response to detecting telescoping movement of the suction pipe relative to the housing.

25. The power tool assembly of claim 24 , wherein the switch is a first switch, wherein the dust collector further includes a second switch electrically connected with the motor, the second battery, and the first switch, and wherein the second switch is toggled between a first switching position in which the electric motor remains deactivated irrespective of actuation of the first switch, a second switching position in which the electric motor may be activated and deactivated automatically in response to actuation of the first switch, and a third switching position in which the electric motor may be activated irrespective of actuation of the first switch.

26. The power tool assembly of claim 25 , further comprising:
a suction head removably coupled to the suction pipe, the suction head including a suction inlet through which a tool bit of the power tool is extendable, and
a nozzle interchangeably coupled to the suction pipe with the suction head, the nozzle being usable with the dust collector without the power tool when the second switch is in the third switching po
