US Patent 9089194 Mobility assistance devices

A mobility assistance device that employs a movable handle assembly and an extension support, both of which are movable between retracted and extended positions. The handle assembly is positioned when extended above a seating surface and provides leverage for a user to use his/her hands to assist in rising. The extendable support extends from a guide element along the floor beyond the center of gravity of the device and user to prevent tipping and to provide stability. When the extendable support and handle are disposed in the retracted position, the device is used like a typical cane, walker or rollator.
