Adjustable Armrest Structure Without Locking Mechanisms

The patent removes the locking mechanism entirely from the armrest system. Instead of using a lock that requires unlocking, the design employs a resilient device (spring) that continuously biases the armrest toward a preferred position, allowing free adjustment without any locking or unlocking actions.

The resilient device automatically maintains the armrest in a preferred position through continuous elastic biasing. The system self-regulates the armrest position without requiring user intervention to lock or unlock, and the armrest naturally returns to its biased position after adjustment.

The patent eliminates the locking mechanism and all associated components (buttons, levers, locks). The entire locking subsystem is extracted and replaced with a simple resilient biasing system consisting of a spring and aperture guide, dramatically reducing mechanical complexity.

The system changes from a discrete locked/unlocked state system to a continuous elastic biasing system. The armrest position is controlled by elastic potential energy storage and release rather than mechanical locking states, simplifying the overall mechanism.

The armrest system transitions from a static locked position to a dynamic equilibrium position. The resilient device creates a continuously adaptable system that can be easily moved but naturally returns to a stable biased position, combining ease of adjustment with positional stability through elastic forces.

The system uses elastic potential energy to create a restoring force that maintains armrest position. When the armrest is displaced from its biased position, the spring stores energy and exerts a restoring force, creating stable equilibrium without requiring locking mechanisms.
