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 wheeled shipping/transport cart includes a cart frame that supports a plurality of wheels. The cart frame supports a plurality of stackable trays. The trays include a tray frame with opposed end members, a plurality of longitudinal support members disposed between the opposed end members, and a plurality of upright members nesting with upright members of an adjacent tray. A support structure is disposed between the opposed end members to form an arc corresponding to a curved surface of an article to be supported by the support structure. A pin is received through each of the upright members of the plurality of stackable trays to retain the stackable trays in a stacked configuration.

A high capacity cargo/container dolly. The cargo/container dolly includes retractable side stops that actively retract a roller linkage assembly upon retraction of the retractable side stops rather than relying on passive gravitational forces for the retraction. In some embodiments, the retractable side stops are configured to avoid hold up on the cargo during retraction. The retractable side stops may be coupled to a retraction mechanism that may be actuated from either side of the cargo/container dolly, as well as from one or both ends of the cargo/container dolly. The dolly may include aspects that accommodates dynamic loads that occur during transport to mitigate inadvertent retraction of the retractable side stops or spurious release of catch assemblies that retains cargo on the dolly. The dolly may also include self-locking roller assemblies that release only in the presence of cargo, and deck modules that protect the deck roller from road spray contamination.

A vehicle is structured for exerting a force on a dolly to move the dolly along a ground surface includes a locking pin mechanism having a locking pin, and a dolly tongue receptacle coupled to the locking pin mechanism so as to be movable with respect to the locking pin mechanism to a first position and a second position. A switch is coupled to the dolly tongue receptacle and structured to be operated by movement of the dolly tongue receptacle from the first position to the second position. The locking pin mechanism is structured to extend the locking pin into an opening formed in the portion of the dolly tongue responsive to operation of the switch.

A system for transporting, transferring, or storing goods including stackable receiving containers, wherein stacking structures in a region of the container bases and mating structures in an upper edge region of a side wall interact to lockably stack receiving containers one on top of the other. At least one roll transport unit has a set-up surface for a receiving container and roller transport unit which connect to longitudinal ends of an adjustable length locking bar. A retaining structure is provided on a first longitudinal end of the locking bar for connecting to the upper edge of the receiving container. A retaining structure is provided on the second longitudinal end of the locking bar for connecting to a mating structure on the roller transport unit. The locking bar has a releasable fixing mechanism for limiting the locking bar length and setting the length to a selected dimension.

A motorcycle carrier with retractable wheels. The present example provides a motorcycle carrier with retractable wheels (carrier) is a structure that allows a motorcycle to be parked on it and secured safely, typically during shipping or storage. The carrier may include wheels that may be extended to aid in moving a motorcycle stored on the carrier. The wheels may be retracted when the motorcycle is no longer being moved. When secured the carrier may also function as a work stand.

A height adjustable plumber's support includes an elongated board having top and bottom major surfaces that extend from a proximal end to a distal end of the elongated board, a cushioned pad covering a central region of the top major surface, a head pad covering the top major surface adjacent the distal end of the elongated board, a foot pad covering the top major surface adjacent the proximal end of the elongated board, and a pair of flexible handles secured to opposite lateral sides of the elongated board. The height adjustable plumber's support includes a foldable support leg secured to the proximal end of the elongated board. The foldable support leg has a vertical section and a horizontally extending section. The foldable support leg is height adjustable for adjusting the height of the proximal end of the elongated board over a floor surface, such as when the distal end of the elongated board is inserted into a cabinet having an elevated base.

A movable bearing device includes a base, a plurality of casters, and a plurality of foot pads. The casters are provided on the bottom of the base. The foot pads are movably connected to the bottom of the base in a way that the foot pads are moved upwards and downwards with respect to the base. When the foot pads are moved downwards until their bottom surfaces each have a height equal to or lower than the bottom edges of the casters, the movable bearing device is supported on the ground by means of the foot pads, such that the movable bearing device cannot be moved. When the foot pads are moved upwards until their bottom surfaces each have a height higher than the bottom edges of the casters, the movable bearing device can be moved by means of the casters so as to facilitate the handling work.

The present invention relates to a storage unit for containment, shipping, and storage of articles. The storage unit includes a base and a frame. In various embodiments, the frame may be generally rectangular and defining a storage region therein. The base of the storage unit is designed to matingly engage with a removable wheeled dolly. In a typical embodiment, the dolly facilitates maneuverability and positioning of the storage unit, particularly in confined areas. In various embodiments, a single dolly may facilitate manipulation of multiple storage units, wherein the dolly may be attached to a storage unit while the storage unit is in use and removed when the storage unit is in long-term storage, thereby reducing the space required to store the storage unit.
