A portable, wheeled cart foldable between stowage and deployed positions automatically captivates and suspends trash bags. A generally U-shaped and inverted main frame extends from a top forming a handle to the lower cart wheels. A companion subframe of generally U-shaped profile is pivoted to the frame. Preferably a foldable platform is provided at the cart base for supporting the trash bag. A wheel assembly axle pivotally connects the platform to the lower ends of the main frame. This allows the platform to fold and nest within the main frame thereby allowing the cart to present a compact profile for ease of storage and transport. The bag is captivated upon a pair of resilient, spaced apart clips that extend transversely across tile cart. These clips extend between and are yieldably, pivotally captivated within tipper suitable aligned orifices formed in the frame legs and the subframe legs. The clips have a mid-segment that is parallel to the handles of the cart. Each end of the clips comprises a friction notch presenting a generally V-shaped profile. The edge adjacent the open end of a trash bag is folded over tile mid-segment with part of the trash bag edge captured by the notch. As the subframe drops freely by gravity, the bag expands, and the pivoted clips frictionally captivate tile bag, and hold it in a deployed, open, trash receptive position. The clips accommodate a wide variety of trash bags.

[ What is claimed is:] [1.] A wheeled utility cart for handling bags, said cart comprising:a rigid, generally U-shaped frame comprising a pair of spaced-apart, parallel, and generally vertically oriented legs and an integral cross-member extending between the legs forming an upper cart handle, the frame legs comprising bottom portions;wheels for enabling locomotion of said cart, said wheels coupled to said frame leg bottom portions;a rigid, generally U-shaped subframe substantially similar in size to said U-shaped frame, said subframe comprising a pair of spaced apart legs and a cross member forming an upper subframe handle, said subframe legs comprising lower portions pivoted to said frame legs above said wheels, the subframe selectively displaceable between a generally flat storage position nested against said frame and a deployed position wherein the subframe is angularly pivoted away from said frame;each frame leg comprising insides facing each other and a plurality of vertically, spaced-apart mounting orifices formed on the inside of the leg, with the mounting orifices on one frame leg facing the other mounting orifices on the other frame leg;each subframe leg comprising insides facing each other and a plurality of vertically, spaced-apart mounting orifices formed on the inside of the subframe leg, with the mounting orifices on one subframe leg facing the other mounting orifices on the other subframe frame leg;a first resilient, horizontally-extending clip for holding a bag, the first clip being yieldably, user-fitted to the frame at a user-selected elevation above said wheels, the first clip pivotally captivated between and within said frame legs below said frame handle, and perpendicularly extending between said frame legs;a second resilient horizontally-extending clip for holding a bag, the second clip being parallel with said first clip and yieldably, user-fitted to the subframe at a user-selected elevation above said wheels, the second clip pivotally captivated between and within said subframe legs below said subframe handle, and perpendicularly extending between said subframe legs;the first and second clips each comprising an elongated mid-portion, a pair of integral clip ends parallel with said mid-portion and adapted to be pivotally fitted within said mounting orifices, and V-shaped notches disposed between said clip ends and said clip mid-portions for captivating said bags; and,a platform pivoted at the bottom of said frame and adapted to be switched between a storage position nested against said frame and a generally horizontally-deployed position beneath said subframe.
