[0001] The utility model relates to a zero-gravity deformable chair frame which can lift the legs of a user lying on the chair frame. Background Art
[0002] There are many types of chairs sold and used on the market. In order to further enhance the comfortable use experience of the chair for the user, a chair with a deformable seat frame has emerged. When the user sits on it, the seat frame will deform, for example, the footrest will be extended so that the user's legs can be naturally laid flat, so that the user can get a comfortable experience.

The control device is electrically connected to the telescopic rod, and controls the rod of the telescopic rod to extend and retract forward and backward. The telescopic rod is an electric push rod. When the telescopic rod receives an electrical signal, it will drive the rod on the telescopic rod to extend and retract forward and backward, and drive the telescopic rod push rod to swing back and forth to drive other components to move.
[0009] Compared with the prior art, the utility model can make the seat frame swing upward and diagonally, and cooperate with the movement of the footrest extending outward at the same time, so that the legs of the user sitting on it can be lifted up and the body can be swung down, and finally it can be swung to a state where the center of gravity of the legs is higher than the center of gravity of the body. This can make the blood in the user's legs flow back, squeeze the veins, and make the blood flow back to the heart quickly, which can avoid venous thrombosis in the user and promote heart function.
[0010] The chair can be switched back and forth between the sitting state and the reclining state by the movement of the telescopic rod. When the chair is in the sitting state, the telescopic rod is in the extended state, the front push rod and the rear push rod are both standing between the seat frame and the bottom frame, the seat frame is flat, and the footrest is retracted to the bottom of the seat frame. When the chair is in the reclining state, the telescopic rod is in the retracted state, the rear push rod swings forward, the front push rod is in the state of tilting and swinging forward, the seat frame is in the state of tilting and swinging with its front end lifted up, and the footrest extends forward from the seat frame.
[0011] When the chair is switched from a reclining state to a sitting state, the telescopic rod extends, pushing the rear push rod backwards until the rear push rod stands up, and the rear push of the rear push rod also pushes the seat frame backwards, so that the front push rod is also pushed backwards to a swing direction of standing up, and the seat frame swings backwards to a flat direction, and the front push rod pushes backwards to directly drive the triangular rotating plate to rotate by pushing the rotating plate auxiliary rod backwards, and the rotation of the triangular rotating plate pulls the foot push rod backwards, so that the foot frame, the first foot seat rod, the second foot seat rod, the third foot seat rod and the fourth foot seat rod are folded inwards toward the seat frame, completing the deformation state.

[0032] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0033] Reference Figure 1-19:The utility model zero gravity deformation chair frame has two use states, namely sitting state and reclining state. The chair can switch back and forth between the sitting state and reclining state through the movement drive of the telescopic rod 5. When the chair is in the sitting state, the telescopic rod 5 is in the extended state, the front push rod 3 and the rear push rod 4 are both standing between the seat frame 2 and the bottom frame 1, the seat frame 2 is flat, and the footrest 6 is retracted to the bottom of the seat frame 2, and the first footrest hole 611 is located below the second footrest hole 621. When the chair is in the reclining state, the telescopic rod 5 is in the shortened state, the front push rod 3 and the rear push rod 4 are both in the forward tilted swinging state, the seat frame 2 is in the tilted swinging state with its front end lifted, and the footrest 6 extends forward from the seat frame 2, and the first footrest hole 611 is located in front of the second footrest hole 621.
[0034] When the seat frame is in the sitting state, the user sits on it and then controls the telescopic rod 5 to shorten through the control device of the seat. Because the rod hole 2 52 cooperates with the rear push hole 3 43, the telescopic rod 5 contracts and drives the rear push rod 4 to swing forward, thereby pushing the seat frame 2 and the front swing rod 3 forward. The seat frame 2 is finally pushed forward to a tilted swing state with its front end raised.
[0035] The following is a reference Figure 2 The swing direction of the cross-sectional view is the reference direction. When only the movement of the triangular rotating plate 7 and the front push rod 3 is considered, when the seat frame 2 is pushed forward, the triangular rotating plate 7 installed on the seat frame 2 will be pushed forward together. Since the front push hole 33 is located between the front push hole 1 31 and the front push hole 2 32, the auxiliary rod hole 2 77 will tend to continuously reduce the distance from the front push hole 33. Then, the rotating plate auxiliary rod 75 installed between the triangular rotating plate 7 and the front push rod 3 pushes the triangular rotating plate 7 to rotate in a clockwise direction with the rotating plate hole 1 71 as the rotation center, thereby pushing the footboard push rod 65 and the backrest push rod 83 forward together. The footboard push rod 65 pushes the fourth foot seat rod 64 forward, and pushes the first foot seat rod 61, the second foot seat rod 62, the third foot seat rod 63, and the fourth foot seat rod 64 forward together until the first foot seat rod hole 611 is located in front of the second foot seat rod hole 621, so that the footboard frame 6 is extended in a nearly flat posture; the backrest push rod 83 pushes forward to swing the backrest swing plate 9 counterclockwise with the swing plate hole 91 as the rotation center, thereby pulling the backrest frame 8 down through the backrest auxiliary push rod 86, and the backrest frame 8 swings counterclockwise with the backrest hole 81 as the rotation center, so that the backrest cushion installed on the backrest frame 8 swings down to a tilted posture. Finally, the seat cushion of the chair frame is lifted to a position higher than the seat cushion with its front end raised and the backrest cushion and the seat cushion swing in a direction that forms a larger obtuse angle.
[0036] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, and these modifications and improvements all fall within the protection scope of the present invention.
