Abstract:
A door-closing device connectable by a linkage assembly between a door and a door frame includes a piston linearly movable between a door-open position and a door-closed position toward which the piston is biased. The piston has first and second sets of rack teeth disposed thereon. A pinion gear is mounted on a rotatable shaft coupled to the linkage assembly, the pinion gear having a first set of gear teeth along a first circumferential portion for engagement with the first set of rack teeth, and a second set of gear teeth along a second circumferential portion for engagement with the second set of rack teeth, the engagement between the first set of pinion gear teeth and the first set of rack teeth providing a first gear ratio, and the engagement of the second set of pinion gear teeth with the second set of rack teeth providing a second gear ratio.

Claim (Index 13):
A door-closing device configured to be connected by an articulated linkage arm assembly between a door and a door frame so as to bias the door from an open position toward a closed position, the door-closing device comprising:\n a piston disposed for linear movement between a door-open position and a door-closed position, the piston being biased toward the door-closed position; first and second sets of rack teeth on the piston, wherein the first set of rack teeth and the second set of rack teeth are arranged linearly; and a pinion gear mounted on a rotatable shaft coupled to the articulated linkage arm assembly, the pinion gear having a first set of pinion gear teeth along a first circumferential portion of the pinion gear and configured to engage the first set of rack teeth, and a second set of pinion gear teeth along a second circumferential portion of the pinion gear and configured to engage the second set of rack teeth, the engagement between the first set of pinion gear teeth and the first set of rack teeth providing a first gear ratio, and the engagement of the second set of pinion gear teeth with the second set of rack teeth providing a second gear ratio.
