Abstract

A person lifting assembly to assist a person who has fallen get to a standing position includes a plurality of legs that define a first set of legs and a second set of legs. Each of the legs has a telescopically adjustable height. A base is attached to each set of legs such that the base has an adjustable height. A pair of armrests that have an adjustable height is included. Each of the armrests is attached to and extends between one of the sets of legs. A plurality of lifting units where each of the legs has a lifting unit mounted therein that extends into an associated one of the pair of armrests. Each of the lifting units extends or retracts an associated one of the legs with respect to the base to lift or lower the base with respect to the floor surface.

a plurality of lifting units, each of said legs having a lifting unit mounted therein and extending into an associated one of said right and left armrests, each of said lifting units extending or retracting associated ones of said legs with respect to said base to lift or lower said base with respect to said floor surface;

a power supply being mounted within one of said armrests and being electrically coupled to said motor; and

a plurality of control switches being mounted in one of said armrest, each of said control switches being electrically coupled to said motor, each of said control switches controlling a vertical movement of each of said legs and each of said armrests.

2. The motorized chair assembly according to claim 1, wherein each of said legs has a top end and a bottom end.

3. The motorized chair assembly according to claim 2, wherein each of said legs has:

a lower portion;

an upper portion telescopically receiving said lower portion, said upper portion being vertically moveable relative to said lower portion;

a wheel being rotatably attached to said bottom end; and

a lock being positioned on said wheel, said lock releasably retaining said wheel in a non-rotational condition.

4. The motorized chair assembly according to claim 1, wherein said base has a front side, a rear side, a first lateral side and a second lateral side.

5. The motorized chair assembly according to claim 4, wherein said first lateral side has said first set of legs attached thereto and said second lateral side has said second set of legs attached thereto.

6. The motorized chair assembly according to claim 3, wherein said base is configured to receive a person thereon and lift the person vertically when each of said legs extend upwardly, said base lying in a horizontal plane, said base being attached to each of said upper portions such that when said upper portion moves vertically said base moves vertically.

7. The motorized chair assembly according to claim 2, wherein each of said armrests has an adjustable height relative to a corresponding one of said first and second sets of legs, each of said armrests having a lower end engaging said top end of a corresponding one of said legs at a fully retracted position.

8. The motorized chair assembly according to claim 3, wherein each of said lifting units includes:

a motor being mounted on an associated one of said legs;

a drive rod being mechanically coupled to said motor, said drive rod rotating in a first direction or a second direction when said motor is turned on, said drive rod being threaded;

a first drive coupler being threadably mounted to said drive rod such that said upper portion extends upwardly from said lower portion when said drive rod is rotated in a first direction and said upper portion extends downwardly toward said lower portion when said drive rod is rotated in a second direction; and

a second drive coupler being positioned in said associated one of said right or left armrests, said second drive coupler being threadably mounted to said drive rod such that each of said associated one of said right or left armrests extends upwardly when said drive rod is rotated in a first direction and extends downwardly toward an associated one of said legs when said drive rod is rotated in a second direction.

9. The motorized chair assembly according to claim 1, wherein said plurality of control switches includes an up button and a down button, said up button actuating each of said lifting units such that said base is lifted upwardly from said floor surface, said down button actuating each of said lifting units such that said base is lowered toward said floor surface.

10. The motorized chair assembly according to claim 1, further including a seat extension being pivotally attached to a bottom side of said base.

11. The motorized chair assembly according to claim 10, further including a drive apparatus being mounted to said base, said drive apparatus being actuated to alternatingly move said seat extension to a deployed position extending outwardly from said base to a stored position extending downwardly from said base.

12. The motorized chair assembly according to claim 1, further including a backrest being attached to and extending upwardly from said rear side.

13. The motorized chair assembly according to claim 1, further including a pair of braces, a first one of said braces being attached to and extending between said bottom ends of each of said legs in said first set of legs, a second one of said braces being attached to and extending between said bottom ends of each of said legs of said second set of legs.
