Quick-Release Tablet Stand Switch to Prevent Accidental Collapse

The patent inverts the control mechanism from a push-button that activates folding to a pull-button that activates extension. The button 32 is designed to be pulled outward to trigger the folding action through the connecting rod 31, rather than being pushed to extend. This inversion makes accidental activation during normal use (when the stand is extended) highly unlikely, as users would need to deliberately pull the button against the return spring 33's resistance.

The return spring 33 is pre-loaded to continuously exert a force that keeps the button 32 in its extended position and resists any unintended pulling motion. This preliminary counter-action prevents accidental folding by requiring a deliberate, forceful pull to overcome the spring's resistance, thereby blocking harmful accidental actions before they can occur.

The connecting rod 31 acts as an intermediary mechanical element between the button 32 and the support plate 21. When the button is pulled, the connecting rod transmits the force to rotate the support plate around the rotating shaft 22, providing controlled and stable angular adjustment. This intermediary mechanism ensures smooth, deliberate movement rather than sudden collapses, reducing the risk of tablet damage.

The return spring 33 provides continuous mechanical feedback by exerting a restoring force on the button 32. This feedback mechanism ensures that the stand remains in a stable extended position during use, as any unintended movement against the spring's force is immediately counteracted. The spring's continuous force monitoring prevents sudden, uncontrolled folding that could cause tablet damage.
