Abstract
A method of securing a vehicle at a desired location using a wheel chocking device (,) having a chock (,) movable between a lowered position and a raised position. The method comprises the steps of positioning the vehicle at the desired location with the chock (,) in the lowered position, raising the chock to the raised position, moving the raised chock toward a wheel of the vehicle, sensing the presence of an obstruction on the vehicle, lowering the raised chock to an intermediate position to allow the chock to pass under the obstruction, and contacting the chock with the wheel. The wheel chocking device (,) includes a drive mechanism (,) that is positioned underneath the chock so that the vehicle actually drives over the drive mechanism. The drive mechanism is simplified with the use of a drive screw (,) and a partial drive nut (,) that facilitates the use of support members (,) for supporting the drive screw at spaced locations along the length of the drive screw. A multi-link chock facilitates use of the device on wheels of varying sizes.
