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. |

1. A rise assisting structure, comprising:
a main body; a seat unit, which is pivotally connected, at one side thereof, to the main body, so as to be rotatable about pivot points defined at the pivot connection; two operation bars, which are each pivotally connected to the main body in such a way that two ends of each of the operation bars are rockable, the operation bars being connected, at one end thereof, to a step board; two support units, which are each of an elastic extendable and retractable arrangement, the support units being each pivotally connected, at one end thereof, to the seat unit, the support units being respectively and pivotally connected, at an opposite end thereof, to an opposite end of the operation bars; wherein the seat unit comprises two bearing racks, a connection bar, and a seat, the bearing racks being opposite to and spaced from each other with a predetermined spacing distance therebetween, the connection bar being connected to the bearing racks and comprising a collapsible structure formed at a middle portion thereof, the seat being made of a flexible material enclosing the bearing racks, one side of the seat and an end of each of the bearing racks being collectively coupled to the main body through the pivot connection. |
