The handle structure is detachably connectable to the first handle structure receiving feature. The seat accessory structure has a seat body and is detachably connectable to the foot deck so as to form a seat-based vehicle. The seat accessory structure has a second handle structure receiving feature thereon. The handle structure is detachably connectable to the second handle structure receiving feature, so as to be positioned for gripping by a secondary person when the secondary person is urging the seat-based vehicle to roll on the ground surface while the user is seated on the seat body.

A disposable cart liner includes a sheet of thin material having a perimeter formed by a first longitudinal edge, an opposing second longitudinal edge, a first lateral edge, and an opposing second lateral edge. A tension fastener is woven through apertures in the perimeter. The sheet fits at least around a handlebar and into a seat portion of a shopping cart. A cape is formed at the periphery.

An infant carrier holder has a floor with a ramp and sidewalls and is mounted to a shopping cart. The ramp and sidewalls can contribute to stably supporting an infant carrier. The holder serves as a mechanical interface between an infant carrier, which can be received in the holder, and the shopping cart. The holder can be concavely shaped to assist in shopping cart nesting in addition to supporting a received infant carrier at a desired angle. The holder can be adjustably mounted to a gate or a basket of the shopping cart and may/may not interfere with nesting operations. The holder permits an infant carrier to be supported on a shopping cart without using a significant amount of shopping cart space or interfering with nesting operations.

A car seat holder is used to support a portable infant car seat by providing a flexible support. The apparatus comprises a first support, a second support, and a canvas. The first support and the second support are elongated members that extend across a shopping cart. The first support and the second support are rigid members that distribute the weight of an infant carriage device. The canvas is a flexible surface that extends from the first support to the second support across the shopping cart. The canvas provides a mechanism for transmitting the weight of the infant carriage device to the first support and the second support. In this way, the first support and second support hold the canvas in optimal position for holding an infant car seat. This arrangement frees up space within a shopping cart.

An adjustable luggage trunk stroller with seat cushion is provided. The luggage trunk stroller has an innovative structure, comprising a casing, a rod assembly, a seat cushion and a seat belt. As comparing to the conventional structure, the casing can be manually rotated for changing the tilt angle of the casing at 0˜90 degrees and fastened to a certain position with the coordination of the rod assembly. When disposing the casing at a certain angle, the seat cushion can be swayed and extended for an infant to sit. Or, when the casing is disposed in a horizontal planar state, the seat cushion can be swayed and folded for the infant to lie flat. Thus, the luggage trunk stroller is capable of carrying the infant during walking. The luggage and the infant can be carried at the same time for effectively improving the added value of the luggage trunk stroller.

A wagon having both a utility mode and a driving mode is disclosed. The wagon includes a chassis and a bucket for conveying at least one object. The object can be an inanimate object, wherein the wagon can be configured in utility mode to be pulled by an operator. Or, the object can be a living being, wherein the wagon can be configured either for the utility mode or a driving mode to be driven and controlled by an occupant of the bucket. Various features enable the wagon to be reconfigurable for a desired design.

A cart has a folded configuration and a deployed configuration. The cart includes two side frames arranged opposite to each other; and a plurality of support members connected between the two side frames. Each side frame includes a vertical synchronization rod with a front foot assembly and a rear foot assembly arranged on two sides of the vertical synchronization rod. The front foot assembly includes a front foot rod with an upper front oscillating rod and a lower front oscillating rod hinged between the vertical synchronization rod and the front foot rod. A bottom of the front foot rod is hinged to a front wheel. The rear foot assembly includes a rear foot rod with an upper rear oscillating rod and a lower rear oscillating rod hinged between the vertical synchronization rod and the rear foot rod. A bottom of the rear foot rod is hinged to a rear wheel.

A station for conducting an infant car seat challenge test includes a first portion, a second portion, and a resilient cushion. The first portion has a top configured as an open-top receptacle. The resilient cushion is disposed in and is coupled to the open-top receptacle. The resilient cushion has a sloped top surface where the sloped top surface is sloped towards a first side of the open-top receptacle. The resilient cushion is adapted to support an infant car seat thereon. The second portion is coupled to the first portion at a second side of the open-top receptacle. The second portion includes a platform positioned above the open-top receptacle wherein the platform is adapted to support an electronic display thereon.
