Patent ID: 7614628

Claim:
A collapsible wheeled cart for transporting a carrying case, comprising a handle extending longitudinally in a direction corresponding to a height of said cart and having a lower end, an upper end and a hand grip at said upper end, said handle being selectively extendable and retractable longitudinally; a support platform pivotally connected to said lower end of said handle for pivotal movement in a direction corresponding to a depth of said cart from a non-deployed position wherein said platform extends along said height of said cart to a developed position wherein said platform extends along said depth of said cart to support a carrying case thereon; a pair of wheel arms each having an outer end carrying a wheel and an inner end pivotally connected to said lower end of said handle for pivotal movement in a direction corresponding to a width of said cart from a non-deployed position wherein said wheel arms extend along said height of said cart to a deployed position wherein said wheel arms extend in opposite directions along said width of said cart to deploy said wheels for rolling movement along a transport surface; an actuator pivotally connected to said platform and to said wheel arms movable longitudinally along said handle from an upper longitudinal position to a lower longitudinal position to pivot said platform and said wheel arms in unison from said non-deployed positions to said deployed positions; a pair of platform arms pivotally connecting said platform to said lower end of said handle, said platform arms having rearward ends pivotally connected to said lower end of said handle on opposite sides of a central longitudinal axis of said handle and having forward ends secured to said platform; a pair of platform struts pivotally connecting said actuator to said platform, said platform struts having rearward ends pivotally connected to said actuator and forward ends respectively pivotally connected to said forward ends of said platform arms; and a pair of wheel struts respectively pivotally connecting said wheel arms to said actuator and having outer ends respectively pivotally connected to outer end portions of said wheel arms and inner ends pivotally connected to said actuator.
