  The reclining movement that bends the support floor of the bed in the longitudinal direction and the sofa conversion movement that bends the support floor of the bed in the width direction can be moved by one actuator, simplifying the structure, and increasing the weight and cost The object is to provide a reclining bed that is easy to handle and is easy to handle.

The present invention provides at least a bed / sofa bottom 4, a bed back bottom 5, a bed bottom 6 and a sofa so that the bed support floor 1 can be bent at a bed bending point 2 in the longitudinal direction and a bed bending point 3 in the width direction of the bed. The back bottom 7 is divided into four, has a support base 8 on the lower side of the support floor 1, and between the longitudinal frames 10 and 10 ′ of the rectangular frame 9 of the support base 8, the bed back raising shaft 11. And a sofa back raising shaft 12 are rotatably connected and fixed. A bed back raising arm 13 and a bed back raising bracket 14 are fixed to the bed back raising shaft 11 at a predetermined angle. The raising arm 15 and the sofa back raising bracket 16 are fixed at a fixed angle, and the bed back raising arm 13 stops the lowering of the bed back raising arm 13 and the sofa back raising arm 15. The topper 17 and the sofa back raising arm stopper 18 are provided on the support base 8 at a position corresponding to the bed back raising arm 13 and the sofa back raising arm 15, and one end of the actuator 19 is rotatably connected to the bed back raising bracket 14. The other end of the actuator 19 is rotatably connected to the sofa back raising bracket 16 and the intermediate length of the extension / contraction length of the actuator 19 is arranged so that the entire support floor 1 takes a flat state. It is a reclining bed that is also used as a sofa.

One end of the actuator 19 is rotatably connected to the bed back raising bracket 14, and the other end of the actuator 19 is rotatably connected to the sofa back raising bracket 16. By arranging the support floor 1 so as to be in a flat state , when the actuator 19 is actuated and driven in the direction extending from the intermediate length, the sofa back raising arm 15 contacts the sofa back raising arm stopper 18 and beyond. Since the sofa does not rotate , the sofa back raising bracket 16 can not rotate . If the actuator 19 is further extended from the state in which the sofa back raising bracket 16 cannot be rotated , the bed back raising bracket 14 is pushed, and the bed back raising arm 13 is rotated upward, so that the bed / sofa bottom 4 and the bed back bottom are pushed. 5 undulates.

Further, when the actuator 19 is reversed and driven in the direction of contraction from the intermediate length , the bed back raising arm 13 comes into contact with the bed back raising arm stopper 17 and does not rotate any more, so the bed back raising bracket 14 is moved downward. Can not rotate . When the actuator 19 is further retracted from the state in which the bed back raising bracket 14 cannot rotate in the downward direction, a force acts in the direction of pulling the sofa back raising bracket 16, and the sofa back raising arm 15 is rotated in the undulation direction so that the bed / sofa can be used. A sofa state is obtained in which the bottom 4 and the sofa back bottom 7 are turned up and down .

  Since the bed / sofa combined bottom 4 and the bed back bottom 5 can be reclined and the bed / sofa combined bottom 4 and the sofa back bottom 7 can be swung up and down to be in the sofa state by one actuator, While reclining in bed, you can enjoy meals, reading, watching TV, and relaxing, and in the daytime you can set the back angle to an arbitrary angle as a normal sofa and spend a relaxing time. By using a single actuator, the structure becomes simple and the overall weight and cost are reduced.

Between the longitudinal frames 10 and 10 ′ of the rectangular frame 9 of the support base 8, a bed back raising shaft 11 and a sofa back raising shaft 12 are rotatably connected and fixed. The arm 13 and the bed back raising bracket 14 are fixed at a certain angle, and the sofa back raising arm 15 and the sofa back raising bracket 16 are fixed at a certain angle on the sofa back raising shaft 12. The bed back raising arm stopper 17 and the sofa back raising arm stopper 18 for stopping the raising arm 15 from descending are provided on the support base 8 at a position corresponding to the bed back raising arm 13 and the sofa back raising arm 15, and the entire support floor 1 is provided. The bed back-raising bracket 14 is positioned so that the telescopic length of the actuator 19 is in the horizontal position with the intermediate length. By connecting and fixing the actuator 19 between the sofa back raising bracket 16 and the sofa back raising bracket 16, it is possible to perform reclining of the back of the bed and conversion to the sofa by one actuator 19.
