| مستخلص: | A chair with lifting mechanism including a linear actuator connected to an underneath side of the seat of a chair. A front edge of the seat is secured to the chair's frame by a pivot, whereas the rear edge of the seat is unattached, thereby permitting the seat to rotate about the pivot. The configuration of the actuator, this is extended or contracted, is dictated by control buttons located on the armrests of the chair that can be pressed by the user to assist him with standing. The actuator is powered by a power source that can be a cable cord for stationary use or a battery that allows the present invention to be relocated. The chair with lifting mechanism presents assistance for those who have mobility problems and struggle with standing from regular chairs. By including a seat that can be raised to a predetermined angle, the user can be lifted until he reaches a comfortable position to continue on his own. |

| Claim: | 1. A lift assist chair, comprising: a chair assembly including a seat secured to a frame by means of a pivot, a backrest, legs and a base, wherein said base is located at a bottommost end of said legs, said seat rotates about said pivot, said chair assembly further includes armrests, said armrests forming lateral spaces that are covered by safety panels, attached to a front portion of the base there is a safety mat configured to prevent said lift assist chair from sliding backwards when weight is applied to a front of the seat; an actuation assembly including an actuator, a base of said actuator is secured to said base, a rod of said actuator is secured to an underneath surface of said seat, thereby, the angle of the seat is subject to configuration of the actuator, this is extended or retracted, said actuator is electrically powered by a power source, said actuator is a linear actuator; an electrical assembly including control buttons, said control buttons are in electrical communication with said actuator, the control buttons are configured to extend and retract said rod when pressed, said control buttons are located on said armrests; when extended, said actuator raises a back end of said seat causing it to slant 45° with respect to the horizontal; and when contracted, said seat rests in horizontal configuration relative to the frame. |
| Claim: | 2. The lift assist chair of claim 1 , wherein said actuator is powered from an A.C. supply source by connecting the power source in the form of an electric cord to an electrical outlet. |
| Claim: | 3. The lift assist chair of claim 1 , wherein said power source is provided in the form of a battery mounted onto said base. |
| Claim: | 4. The lift assist chair of claim 1 , wherein said actuator is affixed therebetween said base and said underneath surface of said seat by means of revolute joints. |
| Claim: | 5. The lift assist chair of claim 4 , wherein said actuator is powered from an A.C. supply source by connecting the power source in the form of an electric cord to an electrical outlet. |
| Claim: | 6. A lift assist chair, consisting of: a chair assembly including a seat secured to a frame by means of a pivot, a backrest, legs and a base, wherein said base is located at a bottommost end of said legs, said seat rotates about said pivot, said chair assembly further includes armrests, said armrests forming lateral spaces that are covered by safety panels, attached to a front portion of the base there is a safety mat configured to prevent said lift assist chair from sliding backwards when weight is applied to a front of the seat; an actuation assembly including an actuator, a base of said actuator is secured to said base by means of revolute joints, a rod of said actuator is secured to an underneath surface of said seat by means of revolute joints, thereby, the angle of the seat is subject to the configuration of the actuator, this is if the rod is extended or retracted, said actuator is electrically powered by a power source, said actuator is a linear actuator; an electrical assembly including control buttons and said power source, said control buttons are in electrical communication with said actuator, the control buttons are configured to extend and retract said rod when pressed, said control buttons are located on said armrests; when extended, said actuator raises a back end of said seat causing it to have a slope of 45° with respect to the horizontal; and when said rod is contracted, said seat rests in horizontal configuration relative to the frame. |
