Abstract

A powered handheld chain driver for driving a chain from a chain fall thereby minimizing the effort required to raise and lower loads. The chain driver comprises an integrated or separated drive motor driving a chain sprocket that drives the chain. The chain sprocket is positioned between a pair of vertical spaced chutes and is engaged within a portion of the chutes. Each spaced chute is split and can be opened in a release configuration, for loading and unloading a chain therein. The chutes also comprise a drive configuration wherein the chutes are closed and the chains are captured within the chutes during chain driver operation. Lateral of each chute is a hand assembly comprising handles for supporting the chain driver with the user's hands. A battery is mounted on one side of the chain driver to supply power to the drive motor via one or more power switches.

Dependent claims

A powered handheld chain driver for driving a chain from a chain fall in an operable mode comprising:

a core plate centered in said chain driver operable to provide chain driver structural support;
a chain sprocket;
said chain sprocket comprising a plurality of sprocket windows inset on the radial perimeter of said chain sprocket for driving links of a chain;
a sprocket first recess;
said plurality of sprocket windows linked by said sprocket first recesses;
a drive motor;
a drive shaft;
said drive shaft coupled to said drive motor and operable to impart torsion on said chain sprocket;
a first chute for directing chain against said chain sprocket;
a second chute for directing chain against said chain sprocket on an opposing side of said chain sprocket;
said first chute spaced parallel to said second chute with said chain sprocket positioned therebetween;
said drive motor and said drive shaft and said chain sprocket coupled to said core plate;
a first handle;
a second handle;
said first handle positioned lateral to said first chute;
said second handle positioned lateral to said second chute;
and,
wherein activation of said drive motor induces consequent rotation of said chain sprocket.
