A dollie (10) for supporting an object (20), the dollie comprising: a holder (30) adapted to support the object above a support surface (40) such that the object rests on or in, or is secured to, the holder; and a mobile structure (50) that supports the holder above the support surface, wherein: the mobile structure comprises a peripheral body (60) and a wheel set (70) comprising a plurality of wheels (71); each wheel (71a-c,i-iii) of the wheel set is spaced radially from an inner-point (31) of the holder and is spaced about the peripheral body from each other adjacent wheel of the wheel set; and the wheel set includes three or more multiple-directional wheels (71a-c).

A steerable omni-directional platform cart is disclosed. In one embodiment the cart may include two motorized wheels which can drive the cart in translational movement. The wheels may be selectably rotated together about a vertical axis so as to provide steering control for the cart. The wheels may also be rotated in opposite clockwise directions to cause the cart to pivot about a vertical axis. In a second embodiment, a motorized wheel is disposed with it axis of rotation disposed at a non-perpendicular angle to the platform. Rotation of the motor driven wheel about the rotational axis provides translational movement for the cart in a defined direction. The rotational axis of the wheel is selectively rotatable about a second axis to thereby selectably rotate the defined direction of translational movement about the second axis to provide steering of the cart. In a third embodiment, a motorized wheel is disposed with its axis of rotation disposed at a non-perpendicular angle to the platform, with the wheel biased out of contact with the support surface but lowerable against the bias and into contact to allow the user to select whether the cart is to be motor or manually driven.

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.

Example edge support devices for a dolly are described. The edge support devices include a body including first and second body sections angled relative to each other, a first engagement assembly extending from a bottom surface of the first body section, and a second engagement assembly extending from a bottom surface of the second body section. The first and second engagement assemblies each include a central protrusion and pairs of side protrusions configured to be inserted into openings in the supporting surface of the dolly. The pairs of side protrusions of the first and second engagement assemblies engage the respective openings of the dolly to detachably couple the body of the edge support devices to the dolly.

An appliance dolly has a platform with a caster wheel and a height adjustable stand disposed at each under side corner. At each upper side corner are a plurality of adjustable stays. The stays are configurable to retain the stands of an appliance which rests upon the stand and dolly.

An automatic guided vehicle according to one aspect of the present invention moves a trolley including a trolley body, wheels attached to the trolley body, and a section to be connected which is provided on the lower surface of the trolley body. The automatic guided vehicle is provided with: a vehicle body; drive wheels attached to the vehicle body; and a connection mechanism which is connected to the trolley, wherein the connection mechanism includes a connecting section disposed on an upper side of the upper surface of the vehicle body so as to be movable horizontally in a first direction, and includes a drive apparatus which moves the connecting section in the first direction and connects the connecting section to the section to be connected.

Embodiments are directed to improving transportation of tubular structures. A roller may have a housing having a vertical axis and one or more upper flanges. The one or more upper flanges may have an upper surface that is transverse and non-perpendicular to the vertical axis of the housing. Optionally, the upper surface may be curved. The roller may have one or more wheels that are rotatably coupled to the housing and that extend downward from the housing.

One embodiment of a wheeled tote includes a multifunctional set of resiliently flexible handles that are suitable for responsively guiding the wheeled tote as it rolls, for lifting the wheeled tote, and for comfortably carrying the wheeled tote in a hands-free manner over extended distances. The wheeled tote includes a zip-top collapsible tote bag comprising a sturdy fabric, and a collapsible frame with swivel casters that is removably attached to the bag with fabric snaps. The wheeled tote is reconfigurable between an expanded configuration and a collapsed configuration for better storage and portability. Stays reinforce the left and right sidewalls of the bag. A bottom insert reinforces the base of the bag, and can be used as an actuator to quickly and easily expand the bag from the collapsed configuration to the expanded configuration. Other embodiments are described and shown.

A lift mechanism. The lift mechanism includes a base configured to support the lift mechanism in an upright position. A neck is upstanding from the base. A lift bracket is coupled to the neck. A coupling bracket includes a U-shape having a base and arms extending from opposing ends of the base. The base is coupled to the lift bracket. A linear actuator is configured to move the lift bracket up and down along the neck.

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.
