Abstract: Adjustable handle assemblies as well as rolling assemblies incorporating the same are provided. The handle assemblies include a push button, a spring-loaded gear, a handle, and a base member, allowing for dynamic adjustment between released and locked positions. Actuation of the push button enables free rotation of the handle or secure locking at a predetermined angle, providing users with ergonomic comfort and stability during transportation. The rolling assembly further includes a robust frame structure, multiple wheel assemblies, and optional telescoping members, accommodating various transportation needs. Embodiments of the invention offer a comprehensive solution for urban commuters, travelers, and household users, combining ergonomic design, intuitive controls, and compact portability for seamless transportation of objects in diverse environments.

Abstract: A collapsible cart configured to convert from a collapsed position to an expanded position, the cart having opposing side walls and a bottom wall, and, in the expanded position, forming one or more open compartments which may be enclosed by a cover comprising one or more panels. The side walls may include one or more pairs of panels rotatably together connected at joints such that distal edges of each pair of panels are rotatable inwardly toward each other and a collapsed position or outwardly away from each other toward an expanded position. Also, disclosed is a motorized collapsible cart.

Abstract: 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, and a bottom wall. The right sidewall comprising a first right panel rotatably coupled to a second right panel. The compressible carts may also include a first lock assembly integrated with the first right panel and the second right panel. The first lock assembly having a first condition for locking the first right panel to the second right panel, and a second condition for unlocking the first right panel from the second right panel.

Abstract: Collapsible carts are disclosed. The collapsible carts include a frame, a load bearing member and a wheel assembly. The wheel assembly includes a housing with a horizontal pin channel and an elongated diagonal channel. The horizontal pin channel may be adapted to guide a pin to transpose horizontally along the horizontal pin channel while rotatably coupling a leg member of the frame to a horizontal section of the load bearing member. The elongated diagonal channel may be adapted to guide the horizontal section of the load bearing member to pivot around a pin axis and move from a horizontal plane in the open condition to a generally vertical plane in the closed condition. The movement of the horizontal section along the elongated diagonal channel actuates the housing to rotate around the generally vertical axis.

Abstract: Embodiments of the present disclosure may include a collapsible cart configured to transition from a closed condition where it may be folded up to an open condition where it may be expanded for use, the collapsible cart including a rigid frame forming a compartment, the rigid frame having a front wall, a rear wall, a right sidewall, a left sidewall, and a bottom wall, the right sidewall and the left sidewall may be configured to fold inwardly in the closed condition. In some embodiments, the right sidewall including a first right panel rotatably coupled to a second right panel. In some embodiments, a retractable handle mechanism is disposed at, within or adjacent the back wall. The retractable handle mechanism includes a hand grip attached to a telescoping assembly. The telescoping assembly is pivotably coupled at a proximal end to the bottom of the rear wall.
