A mobile storage device comprises an exterior frame and an interior storage area within the exterior frame. The exterior frame comprises a seat for sitting on when the mobile storage device is not being rolled or moved. In some embodiments, the seat is movable from a closed position to an open position to access the interior storage frame. A flexible storage bag comprising one or more pockets is able be configured to fit within the interior storage area. In some embodiments, the exterior frame is adjustable to adjust a size of the interior storage area. In some embodiments, the exterior frame is collapsible for storing the mobile storage device.

An example cart inventory system and associated methods are described. The example cart inventory system includes a cart and a detection system. The cart includes a frame, and a shelf movably mounted to the frame and configured to be positioned between an extended position and a folded position. A top surface and a rear surface of the shelf include first and second identifiers, respectively. The detection system is configured to detect the first identifier when the shelf is in the extended position and detect the second identifier when the shelf is positioned in the folded position. In the extended position, the top surface is oriented upwards relative to horizontal and the rear surface is disposed against the frame. In the folded position, the rear surface is oriented upwards relative to horizontal.

A carrier transporter is described which is retractable into a low-profile configuration, and extendable to accommodate a carrier or child seat. An adjustable height bar positions a securing device to coincide with a belt path of the carrier and allow a strap to be lead through the belt path and re-secured back to the bar through a buckle. The base of the carrier is supported by an extendable base platform having grip padding to further secure the base to the transporter. The base platform and wheels move together when retracting the transporter and move away from each other when extending the transporter.

A handcart comprising a frame, a double handle grip, a load accommodating bottom shelf and a load accommodating top shelf, the top shelf being pivotably secured to the double grip handle, wherein the double grip handle of the handcart includes a U shaped top piece which is secured to the double grip handle by bolts that allow the U shaped piece to pivot or swing to a position parallel to the ground. The pivoting or swinging action of the U shaped top piece is accomplished by way of a spring mechanism fitted onto the double grip handle, thereby allowing the pivotably secured top shelf to accommodate heavy loads.

A collapsible cart. The collapsible cart includes a frame with a first end and a second end, and the frame secures to a bracket and a base. The collapsible cart further includes a basket that can hold large and small items, and wheels located on the underside of the base provide for easy movement of the cart. A handle, the bracket, and the base are each affixed to the frame via a pivot and can fold towards the frame forming a collapsed configuration.
