Detailed Description

The utility model is described in further detail below with reference to the accompanying drawings.

The front end of the step sofa frame refers to the direction of the center point of the sofa frame towards the foot cushion frame 5, and the rear end refers to the direction of the center point of the sofa frame towards the push rod frame 6.

Referring to fig. 1-12, the step sofa frame of the present utility model has two use states, namely a sitting state and a reclining chair state. The sofa frame can be switched back and forth through the movement drive of the push rod 63 in two postures of a sitting state and a reclining chair state. In the sitting state, the push rod 63 is in an extended state and in a state of tilting its front end at the upper end, the rear end of the push rod frame 6 is positioned closest to the rear end of the underframe 1, the cushion frame 2 is laid flat, the back rest frame 7 is erected, and the cushion frame 5 is rolled under the cushion frame 2. In the reclining chair state, the push rod 63 is in a shortened state and is in a flat state, the push rod frame 6 is pushed forward and lifted for a certain distance, the cushion frame 2 is inclined towards the upper end by the front end, the cushion subframe 3 drives the cushion frame 2 to further incline by the inclined swing motion towards the upper end by the front end, the backrest frame 7 is swung down, and the cushion foot rest 5 extends out from the lower side of the cushion frame 2 to a position higher than the cushion frame 2. The push rod 63 is mounted between the cushion frame hole six 216 and the push rod hole three 616.

Referring to fig. 1-2, the sofa frame is in a sitting state, when a user sits on the sofa frame, the push rod 63 is controlled to be shortened to be half of the stroke, the cushion subframe 3 is not moved, the rear end of the cushion frame 2 is swung down, the front end of the cushion frame 2 is lifted up, the foot rest 5 is lifted up, the foot rest rotary plate is rotated by taking the rotary plate hole two 112 as an axis, thereby the foot rest push rod 12 is extended forward, the foot rest 5 is fully unfolded forward, the back swing of the cushion frame 2 can enable the back rest frame 7 to move backwards together, and the back rest auxiliary rod 75 enables the back rest frame 7 to do a certain angle of movement of the lower swing of the rear end of the back rest frame 7, but the back rest frame 7 is not swung backwards to a swinging direction for the user to lie down. At this time, the cushion frame 2 is swung down to the dead point position.

Referring to fig. 3, when the push rod 63 continues to be shortened to the maximum stroke, since the cushion frame 2 is at the dead point position, in order that the push rod 63 can continue to operate, the push rod frame 6 is pushed forward first, the forward pushing swing of the push rod frame 6 becomes a forward pushing motion of lifting upward toward the front by the first swing link 61 and the second swing link 62, the first swing link 61 is pushed forward and stands up, the push rod sub hole two 642 is given a force of pushing forward with one upward, thereby lifting the sub frame sub rod 64 and further lifting the cushion sub frame 3, so that the cushion frame 2 placed on the cushion sub frame 3 swings further backward, that is, the positions of the two holes of the cushion frame hole six 216 and the push rod hole three 616 hinged with the push rod 63 are further shortened to the limit. The cushion frame 2 swings backwards to enable the front end of the cushion frame 2 to further lift upwards, and the cushion foot rest 5 arranged on the cushion frame 2 is lifted to a state that the gravity center of the legs of a user is higher than that of the body, so that comfortable experience is achieved. Further back swinging of the cushion frame 2 can further back swinging of the back cushion frame 7, and finally the back swinging of the cushion frame 7 can enable the back of a user to lie on the sofa frame.

The foregoing is merely a preferred embodiment of the present utility model, and it should be noted that modifications and improvements could be made by those skilled in the art without departing from the inventive concept, which falls within the scope of the present utility model.
