Abstract

A driving tool that includes a frame, a motor assembly and a resilient member. The motor assembly is coupled to the frame and includes an electric motor, a flywheel driven by the electric motor, a pinch roller and a driver disposed between the flywheel and the pinch roller. The pinch roller is selectively movable from a first position to a second position to drive the driver into engagement with the flywheel. The driver is movable between a returned position and an extended position. The resilient member is coupled to the frame and biases the driver away from the flywheel to reduce or eliminate contact between the flywheel and the driver when the flywheel is at rest, the driver is in the returned position and the pinch roller is in the first position. A method for operating a driving tool is also provided.

Claims

1. A driving tool comprising:

a frame;

a motor assembly coupled to the frame, the motor assembly including an electric motor, a flywheel driven by the electric motor, a pinch roller and a driver disposed between the flywheel and the pinch roller, the pinch roller being selectively movable from a first position to a second position to drive the driver into engagement with the flywheel, the driver being movable between a returned position and an extended position; and

a resilient member coupled to the frame, the resilient member biasing the driver away from the flywheel to reduce or eliminate contact between the flywheel and the driver when the flywheel is at rest, the driver is in the returned position and the pinch roller is in the first position.

2. The driving tool of claim 1, wherein the resilient member includes a body and at least one arm member, the at least one arm member being coupled to the body at a first end and extending from the body toward the driver.

3. The driving tool of claim 2, wherein the at least one arm member comprises first and second arms that are disposed on opposite lateral sides of the flywheel.

4. The driving tool of claim 2, wherein the driver includes at least one projection and wherein the at least one arm member engages the at least one projection when the driver is in the returned position.

5. The driving tool of claim 1, wherein the driver has a driver body that is configured to engage the flywheel and wherein the resilient member is coupled to the frame forwardly of the flywheel such that at least a portion of the body of the driver passes over a portion of the resilient member when the driver is moved from the returned position to the extended position.

6. The driving tool of claim 5, wherein the portion of the resilient member substantially covers a space between the flywheel and the frame.

7. The driving tool of claim 1, wherein the resilient member includes at least one clip that is removably coupled to the frame.

8. The driving tool of claim 7, wherein the at least one clip includes a C-shaped bracket that engages a rail that is formed on the frame.

9. The driving tool of claim 7, wherein the at least one clip includes a tab having one of a projection and an opening, wherein the frame includes the other one of the projection and the opening and wherein the projection is received into the opening to at least partially secure the resilient member to the frame.

10. The driving toot of claim 1, wherein the driver is spaced apart from the flywheel when the driver is in the returned position.

11. A method of operating a driver comprising:

providing a driver that includes a frame and a motor assembly, the motor assembly being coupled to the frame and including an electric motor, a flywheel driven by the electric motor, a pinch roller and a driver disposed between the flywheel and the pinch roller, the pinch roller being selectively movable from a first position to a second position to drive the driver into engagement with the flywheel, the driver being movable between a returned position and an extended position; and

resiliently supporting the driver on opposite lateral side of the flywheel when the flywheel is at rest, the driver is in the returned position and the pinch roller is in the first position.

12. The method of claim 11, wherein supporting the driver includes resiliently biasing the driver in a direction away from the flywheel.

13. The method of claim 12, wherein supporting the driver includes coupling a pair of cantilevered arm members to the frame.
