Abstract

An accessory for coupling to an attachment mechanism of an oscillating power tool includes a working end, an opposite rear end, and a fitment portion adjacent the rear end portion. The fitment portion includes a central opening having a central portion and a rearward portion open to the rear end, and configured to receive a post of a tool clamping mechanism. The fitment portion further includes a first plurality of openings in communication with and extending radially outward from the central portion, a second plurality of openings not in communication with and positioned radially outward from the central portion. The central portion, the first plurality of openings, and the second plurality of openings are configured to couple the fitment portion to a plurality of different configurations of attachment mechanisms for oscillating power tools.

First claim

What is claimed is:

1. A combination kit comprising: a first oscillating power tool comprising a housing, a motor disposed in the housing, a transmission configured to convert a rotational motion of the motor to an oscillating motion of an output member, and a first accessory attachment mechanism coupled to the output member and having a first central member and a plurality of first circumferential projections spaced radially from the first central member and circumferentially spaced around the first central member; and an accessory comprising a working end portion and an opposite rear end portion configured to be removably coupled to the attachment mechanism, the rear end portion including: (a) a generally central opening open to the rear end portion, the central opening having a central portion and a rearward portion in communication with the central portion and open to the rear end portion of the accessory; (b) a first plurality of openings in communication with and extending radially outward from the central opening, the first plurality of openings including a first radial arm slot extending from the central portion, a second radial arm slot extending from the central portion at approximately 90 degrees to the first radial arm slot, and a third radial arm slot extending from the central portion at approximately 180 degrees to the first radial arm slot; (c) a second plurality of openings not in communication with and positioned radially outward from the central opening, and (d) a pair of notches defined along a pair of opposed edges in the central opening, wherein the central portion is configured to receive the first central member, at least one of the radial arm slots is configured to receive at least a first of the plurality of first circumferential projections, and at least one of the second plurality of openings is configured to receive at least a second of the plurality of first circumferential projections when the accessory is coupled to the first accessory attachment mechanism of the first oscillating power tool, and wherein the rear end portion is configured to be coupled to a second accessory attachment mechanism of a second oscillating power tool, the second accessory attachment mechanism including a second central member configured to be received in the central opening and a plurality of radial arm projections extending radially from the central member and configured to be received in at least one the radial arm slots when the accessory is coupled to the second accessory attachment mechanism of the second oscillating power tool.

2. The kit of claim 1 , wherein the first accessory attachment mechanism comprises a first clamping face that carries the first circumferential projections.

3. The kit of claim 1 , wherein the first central member comprises a central post that extends through the first clamping face.

4. The kit of claim 3 , wherein the first central member comprises a first central projection on the first clamping face.

5. The kit of claim 1 , wherein the first circumferential projections comprise at least eight circumferential projections arranged circumferentially about the first central member at angles of 0, 60, 90, 120, 180, 240, 270, and 300 degrees relative to a line extending through the first central member and one of the first circumferential projections.

6. The kit of claim 1 , wherein the central opening comprises a generally U-shaped opening.

7. The kit of claim 6 , wherein the oscillating accessory includes a pair of chamfers tapering outward from the U-shaped opening to the rear end portion.

8. The kit of claim 7 , further comprising a notch defined between each chamfer and the generally U-shaped opening.

9. The kit of claim 1 , wherein the second plurality of openings includes a first pair of radial openings spaced radially from the central portion and between the first and second radial arm slots, and a second pair of radial openings spaced radially from the central portion and between the second and third radial arm slots.

10. The kit of claim 9 , wherein the first pair of radial openings comprise a first radial opening positioned approximately 30 degrees from the first radial arm slot and a second radial opening positioned approximately 30 degrees from the second radial arm slot, and the second pair of radial openings comprise a third radial opening positioned approximately 30 degrees from the second radial arm slot and a fourth radial opening positioned approximately 30 degrees from the third radial arm slot.

11. A combination kit comprising: a first oscillating power tool comprising a housing, a motor disposed in the housing, a transmission configured to convert a rotational motion of the motor to an oscillating motion of an output member, and a first accessory attachment mechanism coupled to the output member and having a first central member and a plurality of radial arm projections extending radially from the first central member; and an accessory comprising a working end portion and an opposite rear end portion configured to be removably coupled to the attachment mechanism, the rear end portion including: (a) a generally central opening open to the rear end portion, the central opening having a central portion and a rearward portion in communication with the central portion and open to the rear end portion of the accessory; (b) a first plurality of openings in communication with and extending radially outward from the central opening, the first plurality of openings including a first radial arm slot extending from the central portion, a second radial arm slot extending from the central portion at approximately 90 degrees to the first radial arm slot, and a third radial arm slot extending from the central portion at approximately 180 degrees to the first radial arm slot; (c) a second plurality of openings not in communication with and positioned radially outward from the central opening, and (d) a pair of notches defined along a pair of opposed edges in the central opening, wherein the central opening is configured to receive the first central member and at least one of the radial arm slots is configured to receive the at least one of the radial arm projections when the accessory is coupled to the first accessory attachment mechanism of the first oscillating power tool, and wherein the rear end portion is configured to be coupled to a second accessory attachment mechanism of a second oscillating power tool, the second accessory attachment mechanism including a second central member configured to be received in the central opening and a plurality of second projections spaced radially from the second central member and circumferentially spaced around the second central member with at least one of the radial arm slots receiving at least a first of the plurality of second projections, and at least one of the second plurality of openings receiving at least a second of the plurality of second projections when the accessory is coupled to the second accessory attachment mechanism of the second oscillating power tool.

12. The kit of claim 11 , wherein the first accessory attachment mechanism comprises a first clamping face that carries the at least one radial projection.

13. The kit of claim 12 , wherein the first central member comprises a central post that extends through the first clamping face.

14. The kit of claim 13 , wherein the first central member comprises a first central projection on the first clamping face.

15. The kit of claim 11 , wherein the plurality of radial arm projections comprises a first radial arm projection and a second radial arm projection positioned at approximately 180 degrees to t
