A wagon having both a utility mode and a driving mode is disclosed. The wagon includes a chassis and a bucket for conveying at least one object. The object can be an inanimate object, wherein the wagon can be configured in utility mode to be pulled by an operator. Or, the object can be a living being, wherein the wagon can be configured either for the utility mode or a driving mode to be driven and controlled by an occupant of the bucket. Various features enable the wagon to be reconfigurable for a desired design.

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.

Disclosed are methods and apparatus for providing portable or fixed solar array support systems. Embodiments of the invention include an apparatus that holds four 60-cell rooftop-grade solar panels and folds up into a relatively small portable device that easily fits in a garage or shed. When open, the panels are displayed at near the nominal angle to the sun for the region. Adjustable angle supports are available in alternative embodiments.

An apparatus configured to convert between a cart and a lounge chair comprising a bottom portion, backrest portion, a leg rest portion, first and second removable side portions. The backrest and leg rest potions rotatably coupled to the bottom portion and movable between open and upright positions. The first and second removable side portions being coupled to the backrest and leg portions when in the upright positions, wherein an open carton of the cart is formed by the bottom portion and the leg rest and backrest portions when in the upright positions, and the first and second removable side portions when connected to the leg rest and backrest sides, and the leg rest and backrest portions, when in the outward positions, form a seat, a leg rest and a backrest of the lounge chair, respectively, the lounge chair being configured to support a person in a sitting or lounging position.

A cart has a rectangular forward and rear frame structures both pivoted on a common axle carrying two wheels, lengthwise pieces joining side pieces of the frame structures on both sides, implementing triangular sides for the cart and forming an upper plane, other lengthwise pieces joining a cross pieces of the frame structures to form a support plane parallel to and lesser in width than the upper plane, a central two-inch square metal tubing joined below the forward frame structure from the axle structure to beyond an upper extent of the forward frame structure, a yoke assembly with a single front wheel; and a handle structure joined to the rear frame structure at an upper cross piece. The first and second lengthwise pieces serve as sides to restrain cargo loaded in the cart on the support plane formed by the third and fourth lengthwise pieces.

A reusable handling device is specially designed for transporting components of a checkout station to a location within the store where the checkout station is installed. The handling device includes casters and is designed to removably mount to a checkout station component (e.g., bagger) having adjustable feet when there is a need to move or transport the checkout station component (e.g., during installation). Generally, the handling device is configured to extend between and engage two of the adjustable feet of the checkout station component. Two or more handling devices can be mounted to the checkout station component to move the checkout station component during installation and can be removed when finished. After the installation is complete, the handling devices can be returned to the manufacturer or supplier of the checkout station component for use in another installation.

A hamper has a base having a base frame with a base shelf provided inside the base frame, and a plurality of caster assemblies secured to the base frame. A supporting frame assembly has two U-shaped frames, with each U-shaped frame having a horizontal base bar and two vertical bars extending from opposite ends of the base bar, with the two U-shaped frames coupled to each other at the center of each base bar, and with the base bars secured to the base. A fabric body has a plurality of side walls, and four vertical corner sleeve pockets, with each vertical corner sleeve pocket defining a channel that receives a separate vertical bar. A top frame secured to the upper ends of the vertical bars.

Disclosed are hinges having specially-cut sections of steel angle iron that force a solid stop point in the open or closed positions. In some embodiments, the stops may limit the hinges to open no more than 90 degrees. In other embodiments the stops may limit the hinges to open no more than 180 degrees. The hinges provide stability to any structure they are used with.

The present invention discloses a backrest angle adjusting mechanism including a first support, a second support, a locking member and a reset member. The first and second supports are pivotally connected to each other and are respectively connected to a backrest tube and a stroller frame, and multiple engaging stages are formed between the first and second supports. The locking member is slidably provided between the first and second support, and has a lock position and a release position. The locking member is engaged at any engaging stage when at the lock position; when the driving member moves, the locking member is driven to slide and depart from the engaging stage and becomes located at the release position, thereby implementing angle adjustment of the backrest tube. During a folding process of the stroller frame, automatic folding of the backrest tube can be achieved by folding the frame stroller or by a seat fabric pulling the backrest tube that then moves with the stroller frame, thereby better simplifying operations of angle adjustment of the backrest tube and folding of a baby stroller. The present invention further discloses a baby stroller having the backrest angle adjusting mechanism.
