Abstract:
1. An insert apparatus for a preexisting cart having a base surface and side walls defining a containment area, comprising: a support structure having a base portion and a containment portion with an inner area, the base portion configured to operatively engage the preexisting cart, wherein the containment portion comprises a plurality of elongated vertically-extending connector elements having a length and a plurality of horizontally-extending connector elements arranged and attached to thereby create an upstanding support structure, and the base portion includes a plurality of elongated horizontally-extending connector elements configured for sliding engagement with one another such that the base portion is adjustable by a user, thereby allowing the insert apparatus to be re-sized to operatively engage a plurality of variably-sized preexisting carts; and at least one retaining element directly attached between at least two spaced elongated connector elements substantially along the length thereof, thereby creating at least one retaining wall configured to retain a material within the inner area of the containment portion of the support structure, wherein the base portion of the support structure is configured to rest upon the base surface and within the containment area of the preexisting cart, an open area configured to correspond to the confinement area of the preexisting cart is provided between the base portion and a bottom edge of the at least one retaining wall and at least a portion of the base portion of the support structure is configured to contact at least one of the side walls of the preexisting cart, thereby preventing the support structure from sliding or tipping while the cart is in motion.
