Subdividing a door into numerous small horizontal panels that run on tracks mounted in the frame allows for a futuristic yet bakeable portal. This redesign frees the door to function in multiple states. I summarize the new active and passive states thusly.
1) Closed: The panels are down and rotated
to the vertical locking them together and forming a solid door conventional in appearance but lacking a knob.
2) Ventilation with privacy:
The panels are rotated slightly by means of a cam system in the track actuated by lifting all the panels slightly in their tracks. This provides free airflow but complete visual obscurity.
3) Visually open but secure: Panels are lifted slightly more camming them into a completely horizontal position allowing airflow and good visibility out the door.
4) Raised (open): The panels rise in the track nesting one in another in the top of the frame.
Function: The weight of the door is precisely counterbalanced by weights in the frame connected to it by means of a chain or cable. The panel angle is produced by means of rods and springs that act as the panels reach their lowest position. Compression of the panels causes metered rotation into the vertical position). The home owner utilizes the action of a lever or motor to actuate the door. Because the door is precisely counterbalanced the action of the door requires little effort to open or close. Action is gentle and safe and is perfect for the disabled as it has no swing or sill and does not require extensive remodeling.Hands or other objects caught in the door will not be sheered off because the speed and momentum of the system is held to a minimum.
Futuristic door technology for your mod "Forbiden Planet" pad. Whiz Bang action is so extraordinary it will leave guests speechless. So quiet convenient and space saving you won't be able to live without it!
