Abstract
Cooler carts are desirable for transporting coolers. Coolers come in various sizes, and can become quite heavy once filled with ice and food or beverages. The cooler cart adapts to a wide range of cooler sizes by having the ability to telescope both lengthwise and widthwise. A telescoping handle shaft is also provided to adjust the height of the handle. All four corners of the cooler cart are supported by either four wheels mounted on the corners or two legs on the front corners and to wheels on the rear corners. The handle shaft is hingedly mounted, allowing it to be folded down when the cooler cart is not in use.
