A portable payload carrier (e.g., military transit case) comprises a housing for supporting at least one payload therein, and a ground transport assembly coupled to the housing comprising a first transport unit (e.g., cover) in support of a wheel assembly. The wheel assembly can comprise a wheel and at least one wheel support structure configured to support the wheel about the first transport unit. The wheel assembly can be operable between a stowed configuration and a deployed configuration for transporting the portable payload carrier about a ground surface via the wheel by a user. A handle transport assembly can be coupled to an opposing side of the housing, and can include a deployable handle assembly for lifting and moving the portable payload carrier. The wheel and handle assemblies can be collapsible to maintain a form factor of the portable payload carrier when in the stowed configuration.

A ladder transport device for use with a detachable ladder handle. The transport device has an axle and pair of wheels which are mounted on a body. The axle and wheels are rotatable and axially moveable relative to the body. The transport device body is securable to the detachable handle. The detachable handle is securable to the exterior side of a ladder near the end of the ladder. The user can then roll the ladder on the wheels by lifting and pulling on the opposite end of the ladder. Stability is improved by horizontally aligning the cross sectional center of gravity of the ladder between the wheels.

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.

A Wheeled Cart which can be connected in the same manner as the car's own wheel, allowing, upon removal of the car wheel, the positioning of the Wheeled Cart with the same screws or the same nuts, without needing to make any adaptations; the idea was to develop a device that adapts to the different configurations of wheel fastening on wheel holders, according to how it is designed on the wheel holder, which is why a very important point that is taken into account is that the chassis or main body must regulate the layout or configuration of the holes, as well as the diameter of the wheel to be replaced, the objective is to enable movement of the car when the latter cannot do so with its wheels, which is why the device is designed based on two bodies named chassis facing each other, with a common central connection part, one superior part named superior end and one inferior part named inferior end, which accommodates a 360 directional wheel and a third connecting element between the chassis, which affixes the position of the latter with the purpose of securing it; and the device is characterized by the fact that its Body which we name Chassis is comprised of two parts connected in the central area of each of the parts by means of a bolt bushing, and which we will hereinafter name Central Part, and from this Central Part a formation extends to each part of the chassis, in a symmetrical manner, generating what we shall name Superior Ends and the other Inferior Ends; each of the latter accommodates a wheel with its corresponding fork and 360 pivotal axis; and in turn each Superior End has on its extremities through-holes of a greater dimension than that of the adjustment screws for the wheels of the car and of a lesser dimension than the diameter of the nut of that screw or screw head; in turn, between each of the Superior Ends and the Central Part of each part of the body of the chassis there is a screw with a wing nut fixed to the upper body of the chassis, with a component named bridge located between both screws and affixed by the wing nuts, with a through-hole in its central part of the same diameter as the through-holes at the extremities of each of the Superior Ends and this bridge has an oval orifice instead of a circular orifice in the connection with each screw by means of a wing nut.

This invention is directed to a kit of coolers that offers a number of improvements over the prior art. The coolers are modified to specifically accommodate frozen gel ice packs instead of ice cubes. Because there is no spill water, the coolers open with front-facing pull-out drawers. The coolers stack atop one another with interlocking parts. Easy transport is provided by a handle and wheels, which are attached to the bottom (main) bin. Internally, the cooler bins are compartmentalized horizontally or vertically with dividers. Hollow spaces within the walls and dividers of the bins accommodate frozen gel ice packs. Overall, the coolers are easier to pack and unpack, stack, load into a car, and transport on the ground than conventional ice chest coolers.

A galley cart compartment is disclosed. In embodiments, the galley cart compartment includes an interior compartment or space having left and right sidewalls and a cabin floor. The interior compartment can receive and securely store a galley cart (e.g., trolley) insertable into, and removable from, the interior compartment along an axis of entry (e.g., parallel to the depth of the interior compartment). The galley cart has left and right sides and an underside to which casters are pivotably or rotatably attached, each caster has left and right wheels separated by a wheel gap. Tracks extend along the cabin floor parallel to the axis of entry, a left and right track positioned to engage respectively with the left-side and right-side casters. Each track includes a guide rail that projects into the wheel gap, preventing the caster wheels from rotating when the galley cart is removed from the interior compartment.

A support assembly includes a body, a first bearing assembly, a first fastener, and a leg. The body includes a first aperture centered on an axis. The first bearing assembly includes a first ball bearing. The first fastener is threadably engaged with the first aperture. The leg is selectively repositionable along the axis. The leg includes a support. The first fastener is configured to cooperate with the leg to cause repositioning of the support relative to the body in response to rotation of the first fastener within the first aperture.
