  • TOOL-FREE ADJUSTABLE-TORQUE STAND SYSTEM
    Publication number: 20250052362
    Abstract: Methods and systems of tool-free adjustment of torque used to maintain the viewing angle of a display stand are performed. In one exemplary embodiment, a method is performed by a device having a platform hingedly coupled to a base. A bar rotatably supported by the base includes a left-hand threaded portion, a right-hand threaded portion, and a grip configured to enable simultaneous rotation of both threaded portions. A first nut is in threaded engagement with the left-hand threaded portion, and a second nut is in threaded engagement with the right-hand threaded portion. A first spring is coupled to the first nut and the platform, and a second spring is coupled to the second nut and the platform. When the bar is rotated via the grip, the first and second nuts move in opposing directions to enable simultaneous tension adjustment of the first and second springs.
