Duster having a rotatable vacuum pick-up

1. A hand held device for dusting a surface, the device comprising:

A. a housing;

B. a drive motor associated with the housing;

C. a duster having an axis of rotation, a first end, and an axially spaced second end, the duster being rotated about its axis by the drive motor;

D. at least one conduit operatively associated with the housing and having a first portion for attachment to a source of vacuum, and a side portion extending coaxial with the first portion, parallel to the axis of the duster and adjacent to the duster, the side portion having a vacuum inlet extending along the length of the duster for drawing dirt from the duster; the vacuum inlet being selectively rotatable from a first position generally facing toward the duster to a second position generally facing away from the duster, the second position providing access to the vacuum inlet independent of the duster; and

E. a rotating coupling between the first portion and the side portion, the coupling connecting the first and side portions to each other while simultaneously allowing the side portion to rotate about an axis extending generally parallel to the axis of the duster;

the device weighing less than five pounds.

2. The hand-held dusting device of claim 1 , wherein the conduit has a distal end.

3. The hand-held dusting device of claim 2 , further comprising a roller mounted adjacent to the distal end and positioned to make rolling contact with a surface near the surface being dusted.

4. The hand-held dusting device of claim 1 , further comprising a rotating seal between the first portion and the side portion, the seal being adapted to allow a partial vacuum to be drawn from the side portion to the first portion to convey dust from the side portion to the first portion of the conduit.

5. The hand-held dusting device of claim 1 , further comprising a detent associated with the coupling for maintaining the side portion in at least one detent position relative to the first portion of the conduit.

6. The hand-held dusting device of claim 5 , wherein said detent is configured to retain the vacuum inlet of the side portion in a position generally facing toward the duster.

7. The hand-held dusting device of claim 5 , wherein said detent is configured to retain the vacuum inlet of the side portion in a position facing generally away from the duster.

8. The hand-held dusting device of claim 5 , wherein said detent is configured to retain the vacuum inlet of the side portion in a position facing a direction rotationally displaced from the axis of the duster.

9. The hand-held dusting device of claim 1 , further comprising a switch mechanism associated with the housing for actuating the drive motor.

10. The hand-held dusting device of claim 9 , wherein the switch mechanism comprises a lock to hold the switch in the “on” position to keep the duster rotating.

11. The hand-held dusting device of claim 9 , wherein the switch mechanism comprises:

A. a trigger captured by the housing, movable in a first direction between an unlocked “on” position and an “off” position, biased from the unlocked “on” position toward the “off” position, and movable from its unlocked “on” position to a locked “on” position;

B. an abutment engaged by the trigger to resist the bias when the trigger is in its locked “on” position, and not to resist the bias when the trigger is in its unlocked “on” position; and

C. first and second electrical contacts normally biased apart, one of the contacts being operatively connected to the trigger to be closed against the other contact when the trigger is advanced from the “off” position to one of the “on” positions.

12. The hand-held dusting device of claim 11 , wherein the switch mechanism further comprises a lever comprising a fulcrum pivoted to the housing, first and second arms depending from the fulcrum, the first electrical contact operatively connected to the first arm and aligned to contact the second contact when the first arm is pivoted about the fulcrum, and the trigger operatively engaging the second arm to pivot the second arm, causing the first arm to pivot and the contacts to close, when the trigger is moved from the “off” position to one of the “on” positions.

13. The hand-held dusting device of claim 1 , further comprising a battery bracket secured to the housing and electrically connected to the drive motor.

14. The hand-held dusting device of claim 1 , wherein the first portion of the conduit is adapted to couple to a vacuum cleaner hose to draw air and debris into the side portion and out of the first portion of the conduit.

15. The hand-held dusting device of claim 1 , further comprising:

A. a housing comprising first and second shell portions joined at a parting plane, wherein the first shell portion has a cleat slot extending depthwise generally perpendicular to the parting plane; and

B. a cleat supported by the conduit and having a wing portion captured in the cleat slot.
