  • Publication number: 20250072596
    Abstract: A height-adjustable desk includes a base, a desk board assembly, a support arm assembly and a supporter. The desk board assembly is above the base, and the support arm assembly is a rhombic linkage mechanism. The support arm assembly includes a first arm segment, a second arm segment, a third arm segment and a fourth arm segment. Bottom ends of the first and second arm segments rotatably connect with the base, and top ends of the third and fourth arm segments rotatably connect with the desk board assembly. A top end of the first arm segment rotatably connects with a bottom end of the third arm segment, and a top end of the second arm segment rotatably connects with a bottom end of the fourth arm segment. The first and second arm segments, and the third and fourth arm segments connect in an engaging transmission manner, respectively.

  • Publication number: 20240353052
    Abstract: The present disclosure relates to a system for mounting a display on a wall. The system may include at least one hanger assembly arranged in a vertical direction. The hanger assembly includes a hook assembly configured to engage a wall panel and a movable hanger configured to slidably engage with the hook assembly such that the movable hanger slides in a vertical direction. The system may further include an adjustment assembly having at least one adjustment component and an adjustment actuator. The adjustment component includes an abutment surface configured to slidably engage with a support surface of the hook assembly. The adjustment actuator engages the at least one adjustment component such that the adjustment actuator translates in a direction transverse to the vertical direction to drive the adjustment component to also translate in the transverse direction relative to the movable hanger and the movable hanger to translate in the vertical direction.
