Abstract

An oscillating tool includes a housing, a motor housed in the housing and a clamp assembly operatively driven by the motor in an oscillating motion. The clamp assembly can hold an accessory such as a blade or sanding attachment, and the clamp assembly includes a first clamp and a second clamp. The oscillating tool also includes a clamp lever and an actuating lever. The clamp lever is operatively coupled to the first clamp to move the first clamp such that clamp assembly is moved from a closed position to an open position. The actuating lever is operatively coupled to the clamp lever to effect movement of the clamp lever, movement of the clamp lever causing the clamp assembly to move from the closed position to the open position.

First claim

What is claimed is:

1. An oscillating tool, comprising:
a housing;
a motor housed in the housing;
a clamp assembly operatively driven by the motor in an oscillating motion, the clamp assembly including a first clamp and a second clamp, the clamp assembly being configured to hold an accessory;
a clamp lever, the clamp lever operatively coupled to the first clamp to move the first clamp such that clamp assembly is moved from a closed position to an open position;
an actuating lever, the actuating lever operatively coupled to the clamp lever to effect movement of the clamp lever, movement of the clamp lever causing the clamp assembly to move from the closed position to the open position;
wherein the actuating lever is operatively coupled to the clamp lever through a connector such that the actuating lever is remote from the clamp lever;
wherein the clamp lever is rotatable about a clamp lever axis; and
wherein the clamp lever axis is transverse to a longitudinal axis of the motor;
further comprising an output shaft driven by the motor; and
wherein a first end of the clamp lever is on a first side of the output shaft;
wherein a second end of the clamp lever is on a second side of the output shaft; and
wherein the second end of the clamp lever moves a farther distance than the first end of the clamp lever when the movement of the clamp lever causes the clamp assembly to move from the closed position to the open position.

2. The oscillating tool of claim 1 , wherein the connector is a connecting strip.

3. The oscillating tool of claim 1 , wherein the clamp assembly is operatively driven by the motor through the output shaft;
wherein the output shaft has a first end and a second end;
wherein the clamp assembly is disposed at the first end; and
wherein the actuating lever is disposed adjacent to the second end.

4. The oscillating tool of claim 1 , further comprising a locking lever, the locking lever configured to keep the clamp assembly in the open position.

5. The oscillating tool of claim 4 , wherein the locking lever is attached to the actuation lever.

6. The oscillating tool of claim 1 , further comprising a guide groove which guides movement of the clamp lever.

7. The oscillating tool of claim 1 , wherein the first clamp is a sliding clamp.

8. The oscillating tool of claim 1 , wherein the second clamp is a fixed clamp.

9. An oscillating tool, comprising:
a housing;
a motor housed in the housing, the motor having a motor longitudinal axis;
an output shaft driven by the motor in an oscillating motion, the output shaft having an output shaft longitudinal axis;
a foot that receives a power supply for powering the motor;
a clamp assembly operatively driven by the motor through the output shaft in an oscillating motion, the clamp assembly including a first clamp and a second clamp and being configured to hold an accessory;
a clamp lever; and
an actuating lever;
wherein the clamp lever is operatively coupled to the actuating lever;
wherein the actuating lever is configured to be movable by a user; and
wherein movement of the actuating lever causes the clamp lever to move and cause the clamp assembly to change from a closed position to an open position;
wherein the oscillating tool has a front and a rear;
wherein the foot is at the rear of the oscillating tool;
wherein the clamp assembly is at the front of the oscillating tool;
wherein the clamp lever comprises a front end and a rear end;
wherein the clamp lever pivots about an axis at the rear end.

10. The oscillating tool of claim 9 , wherein the actuating lever is at the front of the oscillating tool.

11. The oscillating tool of claim 9 , wherein the actuating lever is at a top of the oscillating tool; and
wherein the clamp assembly is at a bottom of the oscillating tool.

12. The oscillating tool of claim 9 , further comprising a locking lever, the locking lever configured to keep the clamp assembly in the open position.

13. The oscillating tool of claim 9 , further comprising a guide groove which guides movement of the clamp lever.

14. The oscillating tool of claim 9 , wherein the first clamp is a sliding clamp.

15. An oscillating tool, comprising:
a housing;
a motor housed in the housing;
a clamp assembly operatively driven by the motor in an oscillating motion, the clamp assembly including a first clamp and a second clamp and being configured to hold an accessory;
a clamp lever;
an actuator, the actuator being remote from the clamp lever and effecting movement of the clamp lever so as to open the clamp assembly and allow the accessory to be inserted or removed from the clamp assembly;
wherein the clamp lever comprises a first end and a second end;
wherein the clamp lever pivots about a clamp lever axis;
wherein the axis is at the first end of the clamp lever; and
wherein the second end of the clamp lever is remote from the clamp lever axis.

16. The oscillating tool of claim 15 , wherein the clamp lever axis is defined by a pin.

17. The oscillating tool of claim 15 , further comprising an output shaft driven by the motor;
wherein the first end of the clamp lever is on a first side of the output shaft; and
wherein the second end of the clamp lever is on a second side of the output shaft.
