In one embodiment, there is provided an apparatus for retaining and moving an automobile tire, and which includes a pair of tire engagement roller assemblies and a lever actuator assembly coupled to the roller assemblies. The roller assembly includes a movable base frame and a tire engaging roller rotatably coupled to the base frame, and the lever actuator assembly includes a lever arm, a link arm pivotally coupled to the lever arm along a length thereof, and a retention bar for selectively holding the lever and link arms in a fixed position relative to each other. Longitudinal end portions of the lever and link arms are rotatably coupled to associated said roller assemblies. Rotational movement of the lever arm towards a generally upright position effects inward movement of the roller assemblies towards each other to mount the tire disposed therebetween.

    Dans un mode de réalisation, un appareil prévu pour retenir et déplacer un pneu dautomobile comprend une paire densembles rouleaux de mise en prise de pneu et un ensemble actionneur à levier couplé aux ensembles rouleaux. Lensemble rouleau comprend un cadre de base mobile et un rouleau de mise en prise de pneu couplé de manière rotative au cadre de base, et lensemble actionneur à levier comprend un bras de levier, un bras de liaison couplé de manière pivotante au bras de levier le long dune longueur de celui-ci et une barre de retenue pour maintenir sélectivement le levier et les bras de liaison dans une position fixe les uns par rapport aux autres. Les parties dextrémité longitudinale des bras de levier et de liaison sont couplés de manière rotative auxdits ensembles rouleaux associés. Un mouvement de rotation du bras de levier vers une position généralement verticale effectue un mouvement vers lintérieur des ensembles rouleaux les uns vers les autres pour monter le pneu disposé entre eux.
