Abstract

A drive assembly for driving an implement is provided. The drive assembly includes a gear drive mechanism comprising a first drive gear rotatable about a first axis of rotation; a second drive gear rotatable about a second axis of rotation and engaged to the first drive gear; a driven member driven by the second drive gear, engaged to the implement, and rotatable about a third axis of rotation; a lobe; and a flexible link engaged to the first drive gear and the lobe, the flexible link comprising a first loop engaged to the lobe and a second loop engaged to the first drive gear. The drive assembly also includes a handle member engaged to the gear drive mechanism and configured to drive the lobe. The implement is rotated about the third axis of rotation as the handle member is moved from an unfired position to a fired position.

First claim

What is claimed is:

1. A device for driving an implement, comprising:
a gear housing adapted and configured to be attached to a container;
an actuating lever disposed on the gear housing, the actuating lever adapted and configured to pivot about a first axis of rotation; and
a gear drive assembly disposed within the gear housing, the gear drive assembly being driven by the actuating lever to rotate an output shaft about a second axis of rotation that is perpendicular to the first axis of rotation, the output shaft extending from the gear housing into the container, the gear drive assembly further comprising a lobe driven by the actuating lever, and a flexible link engaged to the first drive gear and the lobe, wherein the flexible link comprises a first loop engaged to the lobe and a second loop engaged to the first drive gear, the gear drive assembly further comprising a second drive gear engaged to the first drive gear, wherein the output shaft is driven by the second drive gear; and
wherein the actuating lever is lowered from an upright position in the direction of the gear housing for driving the gear drive assembly, and the first axis of rotation of the actuating lever is offset from the second axis of rotation.

2. The device of claim 1 , wherein the gear housing includes a support surface for a hand of an operator.

3. The device of claim 1 , wherein the implement is driven by the output shaft.

4. The device of claim 1 , wherein the first drive gear is a pinion quarter gear and the second drive gear is a spiral radius gear.
