Abstract: Devices and methods for mobility assistance are disclosed. The disclosed features may assist a person with movement by providing support for the person as the person moves. Further, features for easily storing and transporting items in various compartments of the device are disclosed. Support of the user and/or items may be provided by a lightweight composite structure that further allows for free movement of the user, such as taking full strides while walking or running. The device may further be repeatedly configured between collapsed and deployed configurations via a locking mechanism and an actuatable release. Pivotable joints allow the various sections to be stowed into a smaller, collapsed configuration that is easily carried or otherwise transported, as well as deployed into a larger, deployed configuration for assistance while moving.

Abstract: A retractable vehicle step is attachable to a vehicle or truck, such as at the rear portion. The vehicle step facilitates access to a cargo hold of the vehicle. Advantageously, the vehicle step provides clearance space relative to a tailgate of the vehicle by displacing a stepping member of the vehicle step in a generally lateral direction. The vehicle step desirably has a covered and protected biasing mechanism for transitioning between retracted and extended positions of the stepping member. Another advantage is that the vehicle step is readily attachable to the vehicle using already existing connection members, thereby generally eliminating or mitigating the need for customized retrofitting and avoiding undesirable installation cost and time. Further, the vehicle step may be pulled out from under the vehicle by the foot of a user.

Abstract: Collapsible reusable watertight carrying cases are provided in sizes varying from small containers to large sealable container bins on wheels, to provide large quantities of water to remote areas not served by public water supplies, or where water supplies are unavailable because of weather disasters. The cases are assembled or disassembled from a joined flat space-saving configuration to a functioning case and vice-versa. The sides of the cases are erected progressively by hand by interlocking elements at the corners. The panels also disassemble progressively by being manually pulled apart. When folded into a flat storage or shipping configuration, the panels stay together, resisting unfolding by virtue of snaps which are either molded into the panels or bonded to them. The carrying cases are resistant to water, dirt, bacteria, molds, allergens, and inclement weather.
