A method of securing a vehicle at a desired location using a wheel chocking device (30) having a chock (38) 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 (38) 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 (30) includes a drive mechanism (40) 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 (152) and a partial drive nut (148, 154) that facilitates the use of support members (156) 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.

L'invention concerne un procédé d'immobilisation pour véhicule, reposant sur un dispositif de calage de roue (30) dont la cale (38) passe d'une position basse à une position haute. On place le véhicule à l'endroit voulu, la cale (38) en position basse, et on déplace la cale mise en position haute vers une roue du véhicule jusqu'à sentir la présence d'un élément qui fait obstruction sur la structure du véhicule. On abaisse la cale vers une position intermédiaire pour la glisser sous l'élément structural et la mettre en contact avec la roue. Le dispositif (30) comporte un mécanisme d'entraînement (40) placé sous la cale de sorte que le véhicule roule dessus. Son utilisation est simplifiée par une manette à vis d'entraînement (152) et un écrou de cotrôle partiel (148, 154) améliorant le fonctionnement des supports (156) espacés le long de la manette à vis. Le principe d'une cale à plusieurs sections facilite l'emploi du dispositif sur différentes tailles de roue.
