Adjustable bracket and high-feet sofa

The adjustable bracket is divided into multiple independent connection rods (second connection rod, third connection rod, fourth connection rod) that can move relative to each other. This segmentation allows the mechanism to achieve height adjustment through coordinated movement of individual segments rather than requiring a complex single-piece structure, thereby increasing ground clearance while managing structural complexity.

The patent introduces a vertical dimension to the adjustable mechanism by arranging connection rods at different heights and angles. The second, third, and fourth connection rods are positioned at different vertical levels, creating a multi-dimensional structure that increases the overall height from ground while distributing the mechanical complexity across multiple spatial dimensions rather than concentrating it in a single plane.

The connection rods are designed to be dynamically adjustable rather than fixed, allowing the mechanism volume to change based on the desired configuration. When cleaning is required, the rods can be retracted to minimize mechanism volume and maximize ground clearance. When comfort is prioritized, the rods can be extended to increase sitting height, providing dynamic adaptation between these two requirements.

The second, third, and fourth connection rods are arranged in a nested configuration where smaller rods are positioned within the spatial envelope of larger rods. This nesting allows the mechanism to occupy minimal space when in a compact state, facilitating easy access for cleaning equipment, while still providing sufficient vertical travel to achieve appropriate sitting heights when extended.
