Abstract: Cart bumpers and carts including cart bumpers are described. In one example, a cart bumper can include an outer contact wall, an inner rim that defines an inner surface, where the inner surface comprises recesses, a number of spokes extending between the inner rim and the outer contact wall, a mounting ring that defines an outer surface, where the outer surface is in contact with the inner surface, and a number of protruding ribs configured to engage respective recesses on the inner surface.

Abstract: Cart bumpers and carts including cart bumpers are described. In aspects, a cart bumper includes an outer contact wall, an inner rim, and a plurality of spokes extending from the inner rim to the outer contact wall, each spoke of the plurality of spokes defining a respective path. The outer contact wall and the plurality of spokes are configured to collapse in response to a mechanical force applied on the outer contact wall above a predetermined threshold force.

Abstract: A collapsible cart may include a collapsible frame, a foldable shelf, and an interior support column. The collapsible frame includes a first frame portion and a second frame portion. The frame is configured to move between an open configuration and a collapsed configuration by relative translation between the first frame portion and the second frame portion. The foldable shelf extends between the first frame portion and the second frame portion. The foldable shelf is configured to fold to allow the frame to move from the open configuration to the collapsed configuration. The column transversely extends through a column slot defined by the foldable shelf. The cart further includes at least one column brace slidably coupling the frame to the column. The cart further includes at least one shelf brace slidably coupling the foldable shelf to the column.

Abstract: Systems, methods, and apparatuses are disclosed for locking mechanisms to secure multiple cart components. Example embodiments may include a cart with a lower platform, an upper platform, a first storage area disposed between the lower platform and the upper platform, and a second storage area disposed adjacent to the upper platform. Some embodiments may include a door configured to secure the first storage area, where the door is configured to rotate outwards with respect to the upper platform, a hatch configured to secure the second storage area, where the hatch is configured to rotate upwards with respect to the upper platform, and a locking mechanism coupled to the upper platform and configured to lock both the hatch and the door in a locked position. Unlocking the locking mechanism can unlock both the first access panel and the second access panel.

Abstract: A fluid dosing mechanism may include a dosing vessel, a dosing cylinder, a dial, and a piston. The dosing vessel defines a fluid chamber. The fluid chamber includes an inlet and an outlet. The dosing cylinder is coupled to the dosing vessel and defines an end slidable within the fluid chamber. The dial is rotatably coupled to the dosing cylinder and configured to slide the dosing cylinder to define a dosing volume within the fluid chamber against the end of the dosing cylinder. The dosing volume is fluidically coupled to the inlet and the outlet. The piston is movable between (i) a retention position to retain fluid in the dosing volume and (ii) a discharge position to discharge fluid from the dosing volume of the fluid chamber through the outlet. A cart assembly may include a fluid dosing system including a system housing and the fluid dosing mechanism.
