A hamper has a fabric bag, and a supporting frame assembly that has a foldable wall assembly, a base and a top frame. The foldable wall assembly has a rear frame, a left frame a right frame. The base has a rear side that is pivotally connected with the bottom side of the rear frame, with the left and right sides of the base removably coupled to the bottom sides of the left frame and the right frame, respectively. The top frame has a rear side that is removably coupled to the top side of the rear frame, with the left and right sides of the top frame removably coupled to the top sides of the left frame and the right frame, respectively. The fabric bag has four side walls, each side wall having a lip extending around the upper edge of each side wall, and four vertical corner sleeve pockets.

A vehicle system includes a chassis, a plurality of wheels coupled to the chassis and supporting the chassis for rolling on a surface, and a riding platform coupled to the chassis. The riding platform is for supporting a user behind the chassis when the riding platform is in a downward pivoted state. A linkage connects the riding platform to the chassis for selective pivotal motion relative to the chassis between an upward pivoted state in which the riding platform is pivoted into a position to allow a user to walk behind the chassis and a downward pivoted state in which the user may ride or step on the platform.

Compressible carts and methods for using the same are provided. The compressible carts include a rigid frame having a front wall, a rear wall, a right sidewall, a left sidewall, a bottom wall, a rotatable base panel, a rigid cover panel, a handle, and a plurality of wheel assemblies. The compressible carts may also include on each sidewall one or more fastening mechanisms, such as slideable members cooperatively engaging tracks or fastening connectors, and are movable between an open position to allow the sidewall to fold inwardly, to a closed position to selectively lock the panels of the sidewall. The plurality of wheel assemblies may include a plurality of rotatable swivel wheels mounted underneath the bottom wall, or a plurality of wheels rotatably coupled to a plurality of spokes, where each spoke is coupled to a revolving spindle.

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.

The invention discloses a novel sheet folding trailer, comprising pocket component, front-frame component, rear-frame component, bottom-frame component, wheel component, handle component, wherein vertical skeleton unit of the invention comprises front-frame component and rear-frame component, the pocket component is arranged between front-frame component and rear-frame component, the bottom-frame component comprises front bottom-frame component, rear bottom-frame component, bottom-frame U-shaped hinge, drive tube component, the wheel component comprises universal wheel fork a, universal wheel fork b, directional wheel fork a, directional wheel fork b, torque tube a, torque tube b, the handle component is arranged at one side of front-frame component, the handle component and the front-frame component are connected through linkage component. Through structural optimization, the invention has a small folding height, a large capacity after opening, and has a simple side structure by adopting only two parts, which effectively reduces the product cost, moreover, the folding height thereof will not change.

A motorized cart assembly includes a cart that has a basket, a collapsible frame and a plurality of wheels. The basket has a height that is greater than a width of the basket to accommodate tent poles and a tent. The frame includes a pole support for insertably receiving a respective one of the tent poles to vertically orient the respective tent pole. A drive unit is coupled to the cart and the drive unit is in mechanical communication with respective ones of the wheels. The drive unit rotates the respective wheels when the drive unit is turned on thereby facilitating the cart to be self propelled. The drive unit is in wireless communication with a personal electronic device for remotely controlling the drive unit.

Compressible carts and methods for using the same are provided. The compressible carts include a rigid frame having a front wall, a rear wall, a right sidewall, a left sidewall, a bottom wall, a rotatable base panel, a rigid cover panel, a handle, and a plurality of wheel assemblies. The compressible carts may also include on each sidewall one or more fastening mechanisms, such as slideable members cooperatively engaging tracks or fastening connectors, and are movable between an open position to allow the sidewall to fold inwardly, to a closed position to selectively lock the panels of the sidewall. The plurality of wheel assemblies may include a plurality of rotatable swivel wheels mounted underneath the bottom wall, or a plurality of wheels rotatably coupled to a plurality of spokes, where each spoke is coupled to a revolving spindle.

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.
