Abstract
A driver rebound plate to prevent a fastener driver from rebounding into the drive path and striking additional fasteners at the end of a drive cycle. The driver rebound plate is formed from an elongated body having a mounting portion at a first end and a bearing portion at a second end. A retaining portion is disposed between the mounting portion and the bearing portion and is adjacent to the mounting portion. An impact portion designed to receive the impact of a driver during a return stroke is disposed between the retaining portion and the bearing portion. The impact portion is bent at an oblique angle with respect to the drive axis.

A fastening tool comprising:
- a housing having a housing interior, a forward end, a rearward end, and a support member disposed in the rearward end;
- a drive track defined within the housing interior;
- a driver reciprocally mounted for movement within the drive track along a drive axis to drive a fastener during a drive stroke, the driver having a frontend and a rear end;
- an elastically deformable member operatively connected to the support member and bearing against a rearward end surface;
- and
- a dampening member disposed between the elastically deformable member and the rearward end surface.
A driver rebound plate comprising:
- an elongated body having a mounting portion at a first end thereof and a bearing portion at a second end thereof;
- a retaining portion between the mounting portion and the bearing portion and adjacent to the mounting portion;
- and
- an impact portion disposed between the retaining portion and the bearing portion, the impact portion being bent at an oblique angle with respect to the drive axis.
A method of a controlling rebound of the driver comprising:
- providing a driver reciprocally mounted for movement within a drive track along a drive axis to drive a fastener during a drive stroke, the driver having a front end and a rear end;
- providing a driver rebound plate having an impact portion adapted to receive an impact from the rear end of the driver during a return stroke;
- providing a dampening member to absorb the impact from the driver;
- providing a stop member to receive the front end of the driver in a home position;
- guiding the driver along the drive axis to contact the driver rebound plate;
- deflecting the rear end of the driver out of alignment with the drive axis during the return stroke;
- and
- guiding the front end of the driver toward the stop member.
