Abstract

A clamp arrangement for securing an accessory to an oscillating power tool can include a clamp assembly including a first clamp member that moves relative to the accessory between a closed position wherein the clamp assembly retains the accessory and an open position wherein the first clamp is offset from the accessory permitting removal of the first accessory from the clamp assembly. The clamp assembly can further comprise a second clamp member having a first portion that opposes the first clamp member and cooperates with the first clamp member to clamp the accessory between the first and second clamp members. An attachment plate can carry the clamp assembly. The attachment plate can have a first mating detail formed thereon that is configured to selectively and removably mate with a complementary second mating detail on the power tool in an assembled position.

Claims

1. A clamp arrangement for securing an accessory to an oscillating power tool, the clamp arrangement comprising:

a clamp assembly including a first clamp member that moves relative to the accessory between a closed position wherein the clamp assembly retains the accessory and an open position wherein the first clamp member of the clamp assembly is offset from the accessory permitting removal of the accessory from the clamp assembly while the first clamp member remains coupled to the clamp assembly, the clamp assembly further comprising a second clamp member having a first portion that opposes the first clamp member and cooperates with the first clamp member to clamp the accessory between the first and second clamp members;

an attachment plate that carries the clamp assembly, the attachment plate having a first mating detail formed thereon that is configured to selectively and removably mate with a complementary second mating detail on the power tool in an assembled position; and

a fastener configured to selectively and removably extend through a portion of the attachment plate and rotationally fix the attachment plate to an output member of the power tool;

wherein the fastener comprises a threaded fastener that threadably mates with a complementary threaded bore defined in the output member.

2. The clamp arrangement of claim 1, wherein the clamp assembly and the attachment plate are rotationally fixed with the output member in the assembled position.

3. The clamp arrangement of claim 2, wherein the first mating detail collectively comprises a first mating geometry and a second distinct mating geometry that are configured to selectively and alternatively mate with the complementary second mating detail.

4. The clamp arrangement of claim 3, wherein the second mating detail comprises a first tool geometry on a first oscillating tool and a second tool geometry, distinct from the first tool geometry, on a second oscillating tool, wherein the first mating geometry is configured to mate with the first tool geometry of the first oscillating tool in a first configuration and the second mating geometry is configured to mate with the second tool geometry of the second oscillating tool in a second configuration.

5. The clamp arrangement of claim 3, wherein the first mating geometry comprises a keyed recess formed into the attachment plate and wherein the second mating geometry comprises a plurality of recesses formed around the keyed recess.

6. The clamp arrangement of claim 5, wherein the keyed recess comprises a twelve point star.

7. The claim arrangement of claim 5, wherein the plurality of recesses comprises a plurality of oval recesses arranged around the keyed recess.

8. The clamp arrangement of claim 2, further comprising a lever having a user engagement portion and a pivot portion including a pivot axle, the lever being pivotally coupled to the attachment plate about the pivot axle between a first position, wherein the clamp assembly is in the closed position and a second position wherein movement of the user engagement portion of the lever causes the clamp assembly to be moved to the open position.

9. A clamp arrangement for securing an accessory to an oscillating power tool, the clamp arrangement comprising:

a clamp assembly including a first clamp member that moves relative to the accessory between a closed position wherein the clamp assembly retains the accessory and an open position wherein the first clamp member of the clamp assembly is offset from the accessory permitting removal of the accessory from the clamp assembly while the first clamp member remains coupled to the clamp assembly, the clamp assembly further comprising a second clamp member having a first portion that opposes the first clamp member and cooperates with the first clamp member to clamp the accessory between the first and second clamp members; and

an attachment plate that carries the clamp assembly, the attachment plate having a first mating geometry and a second mating geometry distinct from the first mating geometry formed thereon, wherein the attachment plate is configured to selectively and alternatively mate to a first power tool with the first mating geometry in a first configuration and mate with a second power tool with the second mating geometry in a second configuration.

10. The clamp arrangement of claim 9, further comprising a fastener configured to selectively and removably extend through a portion of the attachment plate and rotationally fix the attachment plate to an output member of the power tool.

11. The clamp arrangement of claim 10, wherein the clamp assembly and the attachment plate are rotationally fixed with the output member in the assembled position.

12. The clamp arrangement of claim 9, wherein the first mating geometry comprises a keyed recess formed into the attachment plate and wherein the second mating geometry comprises a plurality of recesses formed around the keyed recess.

13. The clamp arrangement of claim 9, further comprising a lever having a user engagement portion and a pivot portion including a pivot axle, the lever being pivotally coupled to the attachment plate about the pivot axle between a first position, wherein the clamp assembly is in the closed position and a second position wherein movement of the user engagement portion of the lever causes the clamp assembly to be moved to the open position.
