Disclosed are methods and apparatus for providing portable 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. Embodiments of the foldable solar array system are constructed from steel components, and feature proprietary integrated hinges to minimize the size and complexity of the system. The hinges are specially-cut sections of steel angle iron that force a solid stop point in the open or closed positions. These may be 90° hinges on the panel arms and swing arms, and may be 180° hinges on panel-to-panel hinges. The panel-to-panel hinges also allow for an offset based on the thickness of the solar panels and make the solar panels lay flat when open and stack face to face when closed. The weight from the use of steel is useful to help stabilize the array in windy conditions. Additional weight and/or ground anchors can also be easily applied and are recommended for use in windy environments.

Provided is a carrier including a handle and a load-carrying platform, which enables construction of a multi-tier assembly. A carrier includes caster mounting portions formed on a lower surface of a load-carrying platform, a handle that extends outward from a first side edge portion of the load-carrying platform and has an upper surface with an engaged portion being one of a recess and a through hole, and an engaging portion that projects downward from a lower surface of a second side edge portion opposed to the first side edge portion and is engageable with the engaged portion. Connection of a plurality of carriers achieves an integral and flat placement surface composed of placement surfaces, each being the upper surface of the load-carrying platform of the carrier.

A multi-piece snow sled designed to be transported in a compact form then assembled into a full-sized sled, and more specifically a multi-piece snow sled designed to be transported in a compact form then assembled into a full-sized sled having a rigid floor. The multi-piece sled comprises a front sled body piece, a rear sled body piece, a front interface edge, a rear interface edge, and a plurality of removable fasteners securing the front interface edge to the rear interface edge.

A shopping cart basket comprises one or more modular baskets couplable to a bottom basket having a plurality of wheels extending downwardly to allow the shopping cart basket to roll. Each of the modular baskets has a foldable bottom wall that can act as a bottom of a separate basket or can be folded against a side wall of the modular basket. The modular baskets could be used to hold items within a smaller compartment, and can be combined with the bottom basket to form a roll-able shopping cart having a larger compartment. Such a cart is advantageously used in a store, such as a grocery store, a retail shopping mall, or a home improvement store.

A versatile transport rack uses a center frame and one or two outer frames that are pivotally attached to the center frame on opposing sides thereof. Hinge pin receiver pairs, having vertically aligned openings, are attached to each of one or two vertical rails extending upwardly from the center frame and receive door pin pairs of a vehicle door. Landing implements, such as castors or landing gear, are removably attached to the center frame, the outer frames or both. A deck plate can be attached to one or both of the outer frames.

A waste cart includes a base housing; a center upright having a proximal end and a distal end, wherein the proximal end is secured to the base housing; a top housing secured to the distal end of the center upright, wherein the top housing has two or more disposal openings for two or more separate disposal portions including, a first waste portion which has a first metal detector and an indicator for providing a notification when a metal item passes through the opening; and a second waste portion which includes a second metal detector and an indicator for providing a notification when a metal item passes through the opening; an electronics module which operates each metal detector independently; and an alarm indicator operationally associated with the electronics module which is activated when the electronics module detects the passage of a metal item through an opening into a waste portion.

Animal grooming wagons are presented including: a base having a substantially planar top surface and forming a rectangular shape, where the base includes: a pair of end wall receiving slots each positioned along opposite end portions of the base; a pair of side wall receiving slots each positioned along opposite side portions of the base; removable inserts positioned along the top surface of the base; a front steerable wheeled axle positioned along the front-end portion of the base; a rear wheeled axle positioned along the rear-end portion of the base; a steering bar for steering the front steerable wheeled axle; and an anchor point positioned centrally along the top surface of the base.

Disclosed are methods and apparatus for providing portable or fixed solar array support systems. Embodiments of the invention include an apparatus that holds two multi-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.
