| 20080230329 | Wheel Chock Assembly - A wheel chock assembly is provided having a base member extending axially from a top end to a bottom end, first and second support members whose upper ends are pivotally and slidably engaged with respect to the base member, first and second wheel chocks mounted with respect to the lower ends of the support members, and an adjustment mechanism mounted to the base member. The adjustment mechanism is operatively engaged to the support members to achieve axial movement of their upper ends with respect to the base member to extend and retract them within a range that permits the assembly to grip the wheel of a cart between the wheel chocks. Preferably, the adjustment mechanism is a cord secured to the main member of the base member such that pulling the cord upward draws the main member into the handle of the base member, extending the support members outward, while releasing the cord withdraws the main member from the handle, retracting the support members inward. A method is also provided for securing the wheel of a cart. | 09-25-2008 |
