Mechanism of door handle "2inik" by Kamil Izrailov from russia
designer's own words:
Mechanism of door handle
Mechanism application: Standard height of doorknob is not always convenient for: 1. children. 2. people with disabilities. 3. people with not standard height. 4. people that unexpectedly lost motor functions (dangerous manufactures).
The mechanism consists of a mounted to the conventional door lock controls to duplicate the turning doorknob at a reduced to standard height. Fastening of the lower elements of the doorknob can be made on tape, or screws. That is, when necessary, removing the handle and whole mechanism, leaves the door virtually intact same as it was before adding this doorknob. At this time to resolve a similar problem you would have to embed a second lock on the door and the jamb.
The product comes with handles general design, but it is possible to establish any other standard doorknobs.
