  • postures will affect digestion and cause poor circulation in body parts, including buttocks and legs, resulting in numbness in the feet.
  • the main objective of the present disclosure is to provide an electrically operated multi-functional chair that uses an electric control device to drive the linkage mechanism installed on the underside of the seat to move the seat, leg rest, and backrest synchronously, in order to achieve the result of synchronously adjusting a chair setting of sitting or relining.
  • the structure of the present disclosure comprises a rotatable chair base, a seat, a backrest, and a leg rest that can be folded out from below the seat, wherein
  • the leg rest driven by the drive device, is folded out from below the seat, wherein the drive device is controlled by a controller.
  • the drive device synchronously drives the sliding plate to move, making the backrest to recline synchronously and to create an effect of reclining/lying.
  • FIG. 1 is a structural diagram of the present disclosure.
  • FIG. 2 is an operational schematic diagram ( 1 ) of folding out the leg rest of the present disclosure.
  • FIG. 3 is an operational schematic diagram ( 2 ) of folding out the leg rest of the present disclosure.
  • FIG. 4 is a structural diagram of an embodiment of the present disclosure.
  • FIG. 5 is a side view of FIG. 4 .
  • FIG. 6 is a schematic diagram of adjusting the headrest of the present disclosure.
  • FIG. 7 is an operational schematic diagram ( 1 ) of adjusting the armrest of the present disclosure.
  • FIG. 8 is an operational schematic diagram ( 2 ) of adjusting the armrest of the present disclosure.
  • FIG. 9 is a flow chart block diagram of the controller of the present disclosure.
  • the electrically operated multi-functional chair of the present disclosure comprises a rotatable chair base 1 , a seat 2 , a backrest 3 , and a leg rest 4 that can be folded out from below the seat 2 .
  • the rotatable chair base 1 is connected to the underside of the seat 2 and the rotatable chair base 1 allows the seat 2 to rotate.
  • the rotatable chair base 1 is equipped with casters 11 , so that the chair of the present disclosure can move around easily through the casters 11 .
  • the seat 2 has a drive device 5 installed in the center of the underside thereof; the drive device 5 used in the present disclosure can be an electric cylinder, an electric push bar, or a linear drive equipment.
  • the seat 2 and the leg rest 4 are connected through a linkage bar set 6 , wherein the drive device 5 can drive the linkage bar set 6 to fold the leg rest 4 out from below the seat 2 .
  • the aforementioned methods of folding out the leg rest 4 are illustrated in FIG. 2 and FIG. 3 .
  • the linkage bar set 6 comprises a first connecting bar 61 and a second connecting bar 62 , both configured in a V shape. A first end 611 of the first connecting bar 61 is connected to the seat 2 toward the backend thereof; a second end 612 of the first connecting bar 61 is connected to the leg rest 4 near the backend thereof.
  • a first end 621 of the second connecting bar 62 is connected to the seat 2 at a location toward the frontend thereof; a second end 622 of the second connecting bar 62 is connected to the leg rest 4 near the frontend thereof. Furthermore, a fulcrum 63 is disposed on and between the first connecting bar 61 and the second connecting bar 62 .
  • a third connecting bar 64 is disposed on the lower area of the first end 621 of the second connecting bar 62 .
  • An extension bar 51 of the drive device 5 is connected to the third connecting bar 64 . As illustrated in FIG. 2 and FIG.
  • the drive device 5 is controlled by a controller 7 to drive the extension bar 51 extending forward, which can move the third connecting bar 64 and force the first connecting bar 61 and the second connecting bar 62 to move forward and fold out the leg rest 4 from below the seat 2 .
  • the backrest 3 is disposed in one side of the seat 2 ; the lower end of the backrest 3 is pivoted to a sliding plate 31 ; the sliding plate 31 is connected to the drive device 5 .
