A convertible pallet assembly, and associated method of making the convertible pallet, includes a first, planar pallet surface, and a second, planar support surface spaced therefrom. First and second sidewalls extend in parallel relation between the pallet surface and the support surface from adjacent opposite sides thereof. The sidewalls include first and second wheels with respective rotational axes that extend perpendicular to the sidewalls. An actuation mechanism is associated with each sidewall. The actuation mechanism has (i) a first position that allows the first and second wheels on one side to move upwardly and downwardly relative to the sidewall in a non-load carrying condition, and (ii) a second position such that the first and second wheels on the one side project outwardly from the support surface in a load carrying condition whereby the assembly can be rolled on the wheels as a cart.

A dolly for transporting products thereon, the dolly comprising a top with a product support surface and an opposing underside, a plurality of casters provided on the underside, two of the casters being swivel casters configured to rotate relative to the product support surface; biasing means configured to bias a wheel of each swivel caster towards a first equilibrium position. A plurality of reinforcing ribs provided on the underside; wherein at least one of the reinforcing ribs is a curved reinforcing rib, and; the at least one curved reinforcing rib extends from a first caster mounting area to a second caster mounting area. Further including, a dolly carrier pallet comprising a pallet provided with a dolly receiving layer, wherein the dolly receiving layer is provided with generally rectangular wheel receiving recesses for receiving swivel casters and is provided with generally rectangular wheel receiving recesses for receiving fixed casters.

An adjustable all-terrain dolly system (100) having a chassis assembly (110) that includes a frame (120) which has a right-side rail (122), a left-side rail (124), a first-adjustable cross member (126) and a second-adjustable cross member (128), and a first-rolling assembly (160) to include a first-set of inline wheels (164) and a second-rolling assembly to include a second-set of inline wheels (174) and at least one adjustable-locking mechanism (180). The frame of the dolly system defines a load-supporting platform, and the platform has a length which is at least about twice the front-to-rear length of each of the two sets of wheels. Furthermore, each wheel of the dolly system has a peripheral surface which is shaped to engage the underlying surface at a substantially single point to enhance the maneuverability of the dolly.

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.

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.

A portable storage sled for transporting equipment includes a first elongated member and a second elongated member. At least one connecting member joins the first elongated member to the second elongated member. Each of the first elongated member and the second elongated member includes an extension member that is selectively retractable and extendable therefrom. The first elongated member, the second elongated member, the first extension member and the second extension member include a plurality of ridges extending upwardly therefrom that form an equipment mount between which the equipment is situated. The portable storage sled is selectively adjustable in length and width so that equipment of various sizes can be situated thereon.

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 movable base for a shade structure, such as an umbrella, operable between a movable position and a fixed position. The movable base including a foot pedal to transition between the movable and fixed positions. In one example, the foot pedal operates a locking assembly, such as a plate or linkage assembly that engages with the ground in the fixed position and is raised from the ground in the movable positions.

Robotic vehicle and use thereof for displacing a holder for goods, which is for instance loaded with goods, which vehicle can be operated in an empty position and a loaded position, comprising of (1) moving the robotic vehicle to a position under the holder in a first direction, wherein the robotic vehicle is in the empty position, wherein a holding means is countersunk in a body of the vehicle; (2) lifting the holder, wherein the robotic vehicle lifts the holder by performing a vertical movement of the holding means relative to the wheels of the vehicle, such that the holding means comes into contact with an underside of the holder, wherein the robotic vehicle transfers to the loaded position; (3) rotating driven wheels of the robotic vehicle from the first direction to the second direction without the body of the vehicle being rotated, and (4) displacing the robotic vehicle in the loaded position in a second direction, wherein the first and second direction enclose a mutual angle of between 60 and 120 degrees, preferably 75 and 105 degrees, more preferably 85 and 95 degrees, such as a substantially right angle.

Collapsible reusable watertight carrying cases are provided in sizes varying from small containers without wheels to large sealable container bins on wheels, to provide large quantities of water or other supplies and cargo. The cases are assembled or in disassembled from a joined flat space-saving configuration to a functioning case and vice-versa. The sides of the cases are erected progressively by hand by interlocking self sealing reciprocating channel and channel engaging members elements at the corners. The panels also disassemble progressively by being manually pulled apart. When folded into a flat storage or shipping configuration, the panels stay together, resisting unfolding by virtue of snaps which are either molded into the panels or bonded to them. The carrying cases are resistant to water, dirt, bacteria, molds, allergens, and inclement weather.
