Provided are a chair frame and a chair. The chair frame supports a human waist and back by using a waist support assembly and supports human legs and feet by using a footstool assembly. Meanwhile, when the waist support assembly is unfolded, driven by a second support rod, a second end of a first support rod can swing toward the footstool assembly with a junction between a first end of the first support rod and the second support rod as a rotation center to increase an included angle between a waist support bracket and a seat cushion bracket, that is, increasing an unfolded angle of a backrest and achieving the zero gravity effect. The chair can improve the chair comfort by applying the preceding chair frame.

Provided are an elderly chair support and an elderly chair. A support assembly of the elderly chair support includes a support plate () and an anti-torsion tube () fixedly connected to the support plate (); two ends of a first lifting rod () are pivoted to the support plate () and a base () respectively, and two ends of a second lifting rod () are pivoted to the support plate () and the base () respectively; and a first drive assembly is capable of driving a power rod () to rotate relative to the support plate () to have a first position and a second position, in the case where the power rod () is at the first position, a leg assembly () stretches and the anti-torsion tube () abuts against the base (), in the case where the power rod () is at the second position, the leg assembly () retracts and the anti-torsion tube () has a first distance from the base (), and in the case where the power rod () is at the second position, the first drive assembly is capable of driving the power rod () to drive the support plate () to move synchronously so that the support plate () has a second distance from the base (). The elderly chair support and the elderly chair have high stability and are simple in structure.

Provided are an adjustable bracket and a high-feet sofa. In the adjustable bracket, the transmission rod is in a straight rod structure. A first end of the transmission rod is connected to the fourth connection rod. A second end of the transmission rod is connected to the pedal rod group. The present disclosure provides an adjustable bracket. In the case of the same sitting height, the adjustable mechanism of a sofa has a more compact structure so that the cleaning work of a mop, a vacuum cleaner, or a floor-sweeping robot is facilitated. Moreover, the height of the sofa from the ground is higher, making the sofa more attractive.

Adjustable bracket and high-feet sofa

In a sofa seat stretching device, one end of a second support facing away from a first support, and a second leg rest plate connector are hinged at a fourth hinge point, so that the stretching assembly's stretching speed is reduced in a process of switching from a sitting position state to a lying position state when a driving assembly acts in the same way, and the weightlessness feeling can be effectively avoided. Moreover, the driving assembly drives the stretching assembly so that the process of switching the stretching assembly from the lying position state to the sitting position state is smoother.

Sofa seat stretching device

Provided are an ottoman linkage device, a frame body, and a seat. The ottoman linkage device includes an upper link, a lower link, a middle ottoman link, a first front ottoman link, a second front ottoman link, a first connection link, a second connection link, a front ottoman bracket, and a middle ottoman bracket. The upper link or the lower link is rotatable under a driving force to make the ottoman linkage device unfold or fold. By changing the length of the first connection link and the length of the second connection link, the magnitude of the driving force of the first connection link can be adjusted.
