Provided is a carrier including a handle and a load-carrying platform, which enables construction of a multi-tier assembly. A carrier includes caster mounting portions formed on a lower surface of a load-carrying platform, a handle that extends outward from a first side edge portion of the load-carrying platform and has an upper surface with an engaged portion being one of a recess and a through hole, and an engaging portion that projects downward from a lower surface of a second side edge portion opposed to the first side edge portion and is engageable with the engaged portion. Connection of a plurality of carriers achieves an integral and flat placement surface composed of placement surfaces, each being the upper surface of the load-carrying platform of the carrier.

The object carrier for carrying objects is provided, wherein the engaging portions of the shelf member are engaged with the engaged portions of the frame member from top to bottom in the vertical direction to constitute the engagement state between the shelf member and the frame member, the connection line between the engaged portions constitutes an engagement direction, and the shelf member moves in an engagement releasing direction perpendicular to the engagement direction on a horizontal plane to release the engagement state with the frame member. The lift for removing objects from the object carrier is provided, wherein the bearing portion moves in the vertical direction through the lifting portion and bears the shelf member on which the object is placed under the object carrier, and the bearing portion moves in the horizontal direction through the sliding portion, so as to remove the shelf member and the object altogether.

The invention relates to a manually movable and stackable trolley having a supporting device, wherein, when two trolleys are stacked, a rear region which is only taken up by the rear trolley and a front region which is only taken up by the trolley in front are produced, wherein the supporting device is assigned an electronic weighing device which is equipped with a first and a second weighing cell. The two weighing cells are arranged such that, in the stacked state, the first weighing cell of the rear, inserted trolley is within the rear region, and the second weighing cell of the inserted trolley is outside the front region, and, conversely, the first weighing cell of the trolley in front is outside the rear region, and the second weighing cell of the trolley in front is within the front region, wherein the first weighing cell is directed downwards from the at least one supporting device and the second weighing cell is directed upwards.

A trolley (10), primarily for use as a roll cage, includes a base (16) with wheels (18) and a frame (40) located above said base (16). Poles (28, 30, 32, 34) are used to join the frame to the base and a flexible member (14) such as a tarpaulin sheet with latching clamps or a ratchet strap, are used to create tension between the components, to ensure the integrity of the trolley and to reduce the generation of noise when the trolleys is moving in use.

A method and apparatus for assisting in removing a wheels-on-ground type daughter cart from a mother cart, and a mother cart incorporating such a method and apparatus, utilize a daughter cart ejector apparatus mounted on a mother cart and having a selectively actuatable ejector element for urging the daughter cart to move out of engagement with the mother cart in an unloading direction. The ejector element is configured and operatively connected to bear against the daughter cart and apply force in a manner that assists in initiating movement of the daughter cart in the unloading direction and reorienting casters supporting the daughter cart on an underlying surface from a rolling orientation that is generally parallel to a transport direction of the mother cart, to a rolling orientation that is generally transverse to the transport direction and parallel to the unloading direction.

In one example, a mother cart is provided that is suitable for transporting a daughter cart. The mother cart includes a base frame having a group of wheels configured to allow the mother cart to be moved. The base frame, in turn, includes a loading bay for receiving the daughter cart, and a support surface for supporting the daughter cart. Finally, the base frame includes a primary restraint mechanism for engaging and securing the daughter cart in the loading bay.

Provided herein are aspects of a shopping device and system. In one embodiment, a shopping device includes a weight measurement device configured to weigh products placed thereon; a product interface configured to receive product identifiers; and a controller configured to communicate with a remote database and determine that a product identifier received by the product interface corresponds to a first product placed on the weight measurement device, determine a cost of the first product placed on the weight measurement device, and calculate a cumulative weight and cumulative cost of the first product with one or more products placed on the weight measurement device. Embodiments of a shopping system may also include a product carrying device and a user interface, wherein the user interface may include a visual display, an input interface, and a payment interface.
