Motorized dolly

摘要

A motorized dolly includes an elongated frame, a first and second arc-shaped rail, a first and second pulley, a continuous belt, a motor, a platform, a first and second set of rollers or wheels, a fastener and one or more controls. The first arc-shaped rail has a first radius to a point in space. The second arc-shaped rail has a second radius greater than the first radius. The first and second pulleys are attached to the elongated frame proximate to each end. The continuous belt is movably attached to the first pulley and the second pulley. The motor is operably engaged with the first pulley, the second pulley or the continuous belt. The first and second set of rollers or wheels are attached to the platform and movably engaged with the first and second rails, respectively. The fastener securely is attached to the platform and the continuous belt.

1. A motorized dolly comprising:
an elongated base having a top surface and a longitudinal axis extending between a first end and a second end; a first arc-shaped rail attached to the top surface of the elongated base and having a first radius to a point in space substantially perpendicular to the longitudinal axis; a second arc-shaped rail attached to the top surface of the elongated base and having a second radius greater than the first radius; a first pulley attached to the top surface of the elongated base proximate to the first end; a second pulley attached to the top surface of the elongated base proximate to the second end; a continuous belt moveably attached to the first pulley and the second pulley; a motor operably engaged with the first pulley, the second pulley or the continuous belt; a platform having a bottom surface and a top surface; a first set of rollers or wheels attached to the bottom surface of the platform and moveably engaged with the first rail; a second set of rollers or wheels attached to the bottom surface of the platform and moveably engaged with the second rail; a fastener securely attached to the bottom surface of the platform and the continuous belt; and one or more controls electrically connected to the motor.
