Invention
Key Controller
Mobile door lock indicator
With the Key Controller, you always know whether a door is locked or not. Since the display is placed directly on the key, you can also check if you have really locked the door when you are on the road.
Invention
The proposed invention is a device which indicates whether the door (e.g. house door) has been locked. This way you can be sure that you have locked the door and see immediately if you have forgotten to do so.
Short description
A key cap including indicator is attached to the key and an attachment made of dimensionally stable plastic is attached to the corresponding lock.
When the key is inserted into the lock, a protrusion (called a "nose") on the lock touches the field of view on the key. By locking the lock and the associated turning movement, the nose now pushes the field of view in one direction and the indicator field turns red.
When the lock is unlocked, if the key is turned in the opposite direction, the nose pushes the field of view in the other direction and the key shows green in the display field.
Possible uses of Key Controller
Application
private dwelling
Regardless of whether you are renting or owning a flat: Key Controller can be easily attached to any lock, so you know your home is always well locked.
Commercial business premises
Key Controller can be installed on locks to business premises. The advantage is that the system can also be easily retrofitted to older properties.
Delivery and mounting details
Both parts, the key attachment and the lug on the lock, are delivered in one piece and are joined together in their original form by a small bar. This then breaks during the first application so that the adhesive part is also attached exactly to the lock. This ensures that the Key Controller System is not fitted out of place.
In the case of a horizontal key slot, a template is enclosed so that exact installation of the lug on the lock is also possible here.
