Abstract

An adjustable bed including a stationary frame is supported with legs above a floor. An articulated deck comprising head, seat, leg and foot deck boards hingedly joined together is spaced above the frame with connectors. The connectors include generally inverted U-shaped foot and seat tubes pivotally secured to the frame and secured to the seat and foot deck boards. A motorized drive assembly is operatively coupled to the head deck board and includes arms with are pivotally secured to the frame. Activation of the motorized drive assembly moves the deck boards.

Claims

1. An adjustable bed comprising:

a stationary frame having a pair of opposed side rails, a head end rail and a foot end rail;

supports extending downwardly from said frame;

a pair of generally inverted U-shaped foot tubes pivotally secured to said side rails of said frame;

a pair of generally inverted U-shaped seat tubes pivotally secured to said side rails of said frame;

a head deck board;

a seat deck board secured to said seat tubes and hingedly secured to said head deck board;

a leg deck board hingedly secured to said seat deck board;

a foot deck board hingedly secured to said leg deck board and secured to said foot tubes,

a motorized drive assembly pivotally secured to said side rails of said frame and operatively coupled to said head deck board, wherein activation of said motorized drive assembly causes movement of said deck boards.

2. The adjustable bed of claim 1 wherein said supports are secured to said end rails of said frame.

3. The adjustable bed of claim 1 wherein activation of said motorized drive assembly moves said head deck board between an inclined position and a horizontal flat position.

4. The adjustable bed of claim 3 wherein said seat deck board moves between a forward position and a rear position upon movement of said head deck board.

5. The adjustable bed of claim 1 further comprising clips secured to said seat deck board and said foot deck board, said foot and seat tubes being secured to said clips.

6. The adjustable bed of claim 1 wherein said motorized drive assembly includes a pair of arms pivotally secured to said frame, a motor and a drive tube extending between said arms, wherein-activation of said motor causes rotation of said drive tube.

7. The adjustable bed of claim 6 wherein said motor is an electric motor.

8. The adjustable bed of claim 1 wherein said seat deck board moves towards said head end rail and lowers when said head deck board is inclined.

9. The adjustable bed of claim 1 wherein said seat deck board, said leg deck board and said foot deck board each move towards said head end rail when said head deck board is inclined.

10. An adjustable bed comprising:

a stationary frame;

a pair of generally inverted U-shaped foot tubes pivotally secured to said frame;

a pair of generally inverted U-shaped seat tubes pivotally secured to said frame;

a seat deck board secured to said seat tubes;

a foot deck board secured to said foot tubes,

a leg deck board hingedly secured to said seat deck board and said foot deck board therebetween;

a head deck board hingedly secured to said seat deck board; and

a motorized drive assembly operatively coupled to said head deck board, wherein activation of said motorized drive assembly causes said head deck board to move between an inclined position and a flat position.

11. The adjustable bed of claim 10 wherein said seat deck board, said leg deck board and said foot deck board each move when said head deck board is inclined.

12. The adjustable bed of claim 10 wherein said motorized drive assembly includes a pair of arms pivotally secured to said frame, a motor secured to one of said arms and a drive tube extending between said arms, wherein activation of said motor causes rotation of said drive tube.

13. An adjustable bed comprising:

a stationary frame having a pair of opposed side rails, a head end rail and a foot end rail;

an articulated deck spaced above said stationary frame with connectors, said articulated deck comprising a head deck board, a seat deck board, a leg deck board and a foot deck board hingedly joined to each other, said connectors being pivotally secured to said side rails of said frame and secured to said seat deck board and said foot deck board; and

a motorized drive assembly operatively coupled to said head deck board, wherein activation of said motorized drive assembly causes said seat deck board to move vertically and horizontally.

14. The adjustable bed of claim 13 wherein said frame is supported by legs secured to said frame.

15. The adjustable bed of claim 13 wherein said connectors are inverted U-shaped tubes.

16. The adjustable bed of claim 13 wherein said motorized drive assembly includes a pair of arms pivotally secured to said frame, a motor secured to one of said arms and a drive tube extending between said arms, wherein activation of said motor causes rotation of said drive tube.

17. The adjustable bed of claim 13 wherein said motorized drive assembly is remotely controlled.
