Abstract
A powered reclining lift chair includes a first base member for supporting the chair during the lift mode and a second base member having wheels for selectively transporting the chair from one location to another. The chair is operable through both lift and recline modes, as well as being manually actuated in a lowered position to transfer a portion of the chair weight to the second base member as desired. The manual actuation member is biased toward a first position that maintains two of the wheels above the ground surface.
Claims11
A lift chair for raising and lowering an occupant above a floor, the lift chair comprising:
- a seat having a seat back and a seat portion;
- a first base member constantly engaging the floor;
- means for selectively moving the seat relative to the first base member between raised and lowered positions;
- a second base member operatively associated with the seat and a portion of the second base member in at least partial engagement with the floor in a seat lowered position;
- and
- manual means for selectively actuating the second base member into full contact with the floor, the actuation of the manual means providing for redistributed and shared support of the seat between the first and second base members, the manual actuating means including a lever operatively associated with the first base member and extending outwardly therefrom for selective engagement with the seat, and the lever being pivotable about a pin for selective retraction away from engagement with the seat.
A reclining lift chair for raising and lowering an occupant above a floor, and reclining an occupant between upright and reclined positions, the reclining lift chair comprising:
- a seat having a seat back and a seat portion;
- a first base member engaging the floor;
- single means for selectively moving the seat between raised and lowered positions, and between upright and reclined positions;
- a second base member operatively associated with the seat and a portion of the second base member in at least partial engagement with the floor in a seat lowered position;
- and
- manual means for selectively actuating the second base member into full contact with the floor, the manual actuating means including a first portion secured to the first base member and a lever pivotally secured to the first portion for movement between actuated and de-actuated positions, the lever having a first end for engaging the seat in a seat lowered position when the lever is in its de-actuated position, and spaced from the seat in its actuated position the actuation of the manual means providing for shared support of the seat between the first and second base members.
A lift chair for raising and lowering an occupant above a floor, the lift chair comprising:
- a seat having a seat back and a seat portion;
- a first base member constantly engaging the floor;
- ram means powered by a motor for selectively moving the seat relative to the first base member between raised and lowered positions;
- a second base member operatively associated with the seat and being moved with the seat during raising and lowering thereof, the second base member including two pairs of wheels for assisting in movement of the chair, one pair of the wheels engaging the floor during a seat lowered position;
- and
- manual means for selectively actuating the second pair of wheels of the second base member into full contact with the floor, the actuation of the manual means redistributing support of the lift chair between the first and second base members.
A reclining lift chair for raising and lowering an occupant above a floor, and reclining an occupant between upright and reclined positions, the reclining lift chair comprising:
- a seat having a seat back and a seat portion;
- a first base member constantly engaging the floor;
- means for selectively moving the seat between raised and lowered positions, and between upright and reclined positions;
- a second base member operatively associated with the seat and a portion of the second base member in at least partial engagement with the floor in a seat lowered position;
- and
- manual means for selectively actuating the second base member into full contact with the floor, the manual actuating means including a first portion secured to the first base member and a lever pivotally secured to the first portion for movement between actuated and de-actuated positions, the lever having a first end for engaging the seat in a seat lowered position when the lever is in its de-actuated position, and spaced from the seat in its actuated position to provide for shared support of the seat between the first and second base members.
