A convertible cart allows for carriage of many items of different shapes in a position that provides a base with front and back walls, along with structural rods preventing items from sliding out of either side. A two-level tiered configuration may be best suited for carriage of larger, fragile items which cannot be stacked atop each other, or simply for organization of different large items. For the largest loads, a flat base arrangement maximizes both vertical space and available base area while providing the handlebar at an appropriate position for pushing or pulling. When transportation of items is complete, a flat configuration minimizes necessary storage space for the apparatus. These different arrangements are made possible through the employment of several rigid and telescoping members, which enable both custom handlebar arrangement and secure, intuitive adjustment between configurations. Swiveling wheels improve the mobility of the apparatus during 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.

One or more devices are provided that are configured to detachably engage within a modular system. The one or more devices are expandable to provide a surface to perform work.

A rollable table assembly for employing a table as a cart includes a table comprising a first half that is slidably coupled to a second half. A handle is slidably integrated into the table for gripping. A plurality of first wheels and a plurality of second wheels are each rotatably coupled to the table for rolling along the support surface. A plurality of light emitters is each coupled to the table. Each of the light emitters emits light when the light emitters are turned on to illuminate an area.

One or more devices are provided that are configured to detachably engage within a modular system. The one or more devices are positionable to provide a support structure upon which work can be performed.

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 mobile cart, convertible to a canopy shelter, scissor member rectilinear expandable side frameworks having closed, fully open and intermediate modes. A canopy framework of extendable canopy struts. A central hub pivotally connected to upper strut ends. Vertically extendable legs having corner joints pivotally connected to lower strut ends and to adjacent side scissor frameworks. Each leg has a wheel. A fabric canopy cover on the expanded side framework when the struts form a pitched frame. Struts have a substantially closed, vertical stand mode when telescopically collapsed. Struts have a cart-floor mode at an intermediate length when legs are intermediate height, forming an open top wheeled cart. Fully collapsed, canopy cover is interstitial vertical standing struts and collapsed side frameworks. Method from compact form, extending frameworks and struts first to intermediate rectilinear position for the cart-mode; then lifting hub, extending struts while extending the frameworks to a canopy deployed position.

A modular configurable mobile transport apparatus with adjustable folding legs. A modular configurable mobile transport apparatus. The apparatus includes a first roller tip handle facing backwards for grasping the apparatus from behind providing horizontal stability for the apparatus and allowing the apparatus to be rolled on the first roller tip handle, a configurable backwards facing securing and storing portion for securing and storing one or more objects of varying widths to the back surface of the apparatus, a configurable backwards facing securing and storing portion for securing and storing one or more objects of varying widths to the front surface of the apparatus and a second roller tip handle facing forward for providing vertical stability for the apparatus and allowing the apparatus to be rolled on the second roller tip handle. The apparatus can be loaded with objects that are secured and stored on both the front side and back side of the apparatus and the apparatus can be rolled on its wheels and either of the first or second tip handles to allow easy movement and transport and insertion and removal into and out of vehicles. The apparatus includes a set of attachable, removable and adjustable folding legs allowing the apparatus to be used as a work surface on even or uneven surfaces.
