A container with an axle-less wheel assembly can include: a substantially hollow body including a first wheel retention portion and a second wheel retention portion; and a wheel assembly including a first wheel including a shaft continuously formed with the first wheel extending from a center portion of the first wheel, and a second wheel including a shaft continuously formed with the second wheel extending from a center portion of the second wheel. The first wheel can be rotatably secured in the first wheel retention portion when the shaft is inserted into the first wheel retention portion, and the second wheel can be rotatably secured in the second wheel retention portion when the shaft is inserted into the second wheel retention portion. The first wheel can be uncoupled to the second wheel such that the first wheel and the second wheel operate independently from each other.

A collapsible, motorized cargo cart includes an electric motor and a foldable frame that folds down flat for storage and transport. The frame member includes upper and lower frame portions in pivoting relation, and they can be positioned and locked at any desired angle with respect to each other. The lower frame member includes an extension that may be extended or retracted, as desired. Handlebars are provided on the upper frame member, and a throttle controls the speed of the cart, which is capable of transporting at least 300 pounds over rough terrain. Two large wheels are positioned on either side of the cart, and a removable caster wheel may be attached to a front portion of the frame. An electric motor and rechargeable battery are disposed on an underside of the frame's lower portion, and include a drive assembly to power the side wheels.

A truss structure is suitable for supporting lighting fixtures or other loads both in use and in transport. The truss has at least four elongated chords defining between said chords a first volume generally rectangular in cross-section. In transport, the truss is supported substantially above a surface by castered carriages bearing upon that surface, the carriages connected to said truss and in a first position producing an additional volume between said first volume and said surface. The carriages are attached to the truss so as to permit their rotation between said first position and at least a second position suitable for use while remaining connected to said truss.

A device and method of using a Multi-functional utility cart comprising a base, an axle and wheel assembly, a lower structure, and an upper structure, wherein said axle and wheel assembly are attached to base, base is pivotally attached to lower structure, two upper structural vertical tube frames are slide ably connected to two lower structural vertical tube frames, a rotational tray connected to the upper vertical structural tube frames, a foldable base is connected to the two lower structural vertical tube frames; wherein a user elects to collapse said multi-functional utility cart for easy storage and folding, wherein user would minimize the size of said collapsible frame by sliding two upper vertical tubes into two lower vertical tube frames and user would fold up said base; and wherein said multi-functional utility cart has four types of wheel designs and locations that can be utilized for different tasks.

A collapsible support structure includes a horizontal support structure, a vertical support structure, a handle assembly, and an axle assembly. In use, the collapsible support structure may be folded/unfolded between a deployed configuration, in which the collapsible support structure may be capable of rolling along a support surface to transport items, and a stowed/storage position, in which the collapsible support structure is collapsed in a compact geometry for storage. The collapsible support structure includes an axle assembly that enables removal of the wheels from the axle assembly for storage, as well as a handle assembly that can slide completely underneath the horizontal support structure for storage and when not in use.

An axle kit apparatus for increasing the mobility of foldable sawhorse stands while allowing the tires used to be customizable. The invention consists of an axle that connects all of the pieces together. It is mounted with two fasteners that pass through the axle. Two spindles thread into the axle to allow them to be removable. Two objects with threaded apertures lock the spindles in place as well as provide the necessary preload to the bearing races of any tire used. The invention allows for any size spindle and tires to be used as long as the spindle can thread into the axle.

This invention is directed toward a wheel assembly that can easily be attached and detached from a casespecifically in a preferred embodiment an SKB 3i series casesuch that the case can be wheeled when needed, but have the wheels removed for storage or transportation in a vehicle or plane. The wheel assembly comes in three partsan axel, two wheels, and two wheel mountsso it is simple to assembly, and because it has no moving parts, it is solid and durable.
