  • Handle-propelled container having extending and retracting wheels
    Patent number: 5228706
    Abstract: In a container, e.g., a beach cooler, of the type having a pull handle and a pair of retractable wheels the improvement includes a pair of struts (one on either container side) and a pair of strut-positioned wheel assemblies, each mounted for pivoting movement. The U-shaped handle is linearly extensible and retractable and has two arms, each of which includes a cam-like surface. Each such surface bears against a strut for pivoting the wheels between extended and retracted positions, respectively, when the handle is extended or retracted.
