  • Publication number: 20150272798
    Abstract: A rise assisting structure includes a main body, a seat unit, two operation bars, and two support units. The seat unit is pivotally connected, at one side thereof, to the main body. The operation bars are pivotally mounted to the main body. The operation bars are provided at one end thereof with a step board arranged therebetween. The support units are each of an elastic extendable/retractable arrangement. When the step board is treaded down, the operation bars provide a torque in a way similar to a seesaw and the support units provide an elastically-support upward-pushing effect to raise up the seat unit so as to allow a user, with or without the assistance of an attendant person, to rise and stand up easily.
