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.

A dolly assembly includes a parent dolly including a support frame that defines a truck-receiving volume. A child dolly includes a support frame that is sized to be received within the truck-receiving volume. The child dolly includes a child dolly carousel. The parent dolly and the child dolly together include a locking assembly including a locking arm that prevents rotation of the child dolly carousel in a locked position.

The present invention relates to a novel trolley coupling structure that allows coupling of base parts of trolleys aligned in the vertical or horizontal direction. The present invention provides a trolley coupling structure in which a first receiving recess part is provided in a base part of one trolley, a second receiving recess part is provided in a base part of another trolley, a locking member is pivotally attached to the first receiving recess part, a recess part body and a bent section are formed in the respective first and second receiving recess parts, and retaining of the locking member is achieved by constraining and locking a constraining piece part of the locking member at the bent section.

A linkage for interconnecting material handling equipment of a convoy is provided. The linkage comprises a rod having first and second opposite ends, a first pivot joint between the first end and the second end, the first pivot joint having a first pivot axis extending transversely to a longitudinal axis of the rod. A biasing member is secured to the rod and deformable upon rotation of the first pivot joint about the first pivot axis. The biasing member resists at least partially to the rotation of the first pivot joint about the first pivot axis. A first coupling and a second coupling are respectively pivotally mounted to the first end and the second end of the rod for rotation about respective pivot axes transverse to both the longitudinal axis of the rod and the first pivot axis.

Devices described in this disclosure can interconnect a wheelchair with another wheeled apparatus. For example, this document describes interfacing devices that releasably receive the front wheels of a wheelchair and the rear wheels of another wheeled apparatus in such a way that a user of the wheelchair can conveniently maneuver the wheeled apparatus in conjunction with the operation of the wheelchair.

A method of using a flat headed mop is provided. The method includes cleaning a surface with the mop pad, then rotating the mop head into the folded position at a instance with a biasing member coupled to a hinge assembly. The hinge assembly being disposed between the mop head and a mop pole. Next, inserting the mop head into a first fluid to remove contaminants from the mop pad, then inserting the mop head into a wringing assembly to remove at least a portion of the first fluid.
