Definitions

  • the present invention relates generally to portable helping aids for people with walking difficulties, such as the elderly or disabled, to help the user to stand-up and sit down, go up and down stairs.
  • the user of walker leans on it while walking.
  • some users due to bad physical conditions (e.g., very old or with slight disability or after trauma), have difficulty standing up to be in a position to lean on the walker, or have difficulty using the walker to negotiate stairs.
  • the present invention provides a motorized lifting aid for a walker, which enables the user to rise from a sitting position or go from standing to sitting and to climb up and down steps and stairs.
  • the walker also has a foldable hammock seat for rest.
  • the system utilizes a motorized lifting pole in the walker frame and foldable armpit supports to support the user under the armpits.
  • the foldable armpit supports are deployed automatically when the motorized lifting pole starts to rise. After use, the armpit supports fold back to the retracted position.
  • the system includes adjustable legs on the front and back walker frame.
  • the lengths of these legs change in accordance with steps or stairs so that the user is safely supported while climbing up and down stairs, while simultaneously being supported by the armpit supports.
  • the system includes a foldable hammock seat, which may be made of a fabric-like material.
  • the system is operated by an electro-mechanic system powered by a rechargeable battery.
  • the system is operated by the user at any desired speed and support height.
  • both operating switches on both walker handles, may be operated together.
  • the wheels, legs and armpit supports may be provided with safety brakes and sensors for safe operation.
