Key Aid Turner

USER

People with rheumatoid arthritis or similar conditions who cannot put strain on their joints but need to lock and unlock keys by themselves

WHAT

Because it is spherical, it reduces the strain on the fingertips and allows the key to be locked and unlocked with light force. The protruding part of the key is designed to be inserted into the Key Aid Turner, and that part is hollowed out so that you can check the state of the lock (is it open or closed?).

TPU was used so that it fits the shape of the key. Because spherical shapes are stacked together, the fingers catch on it easily, which improves operability. The size has been adjusted in consideration of the user's hand size, range of motion and muscle strength.

A supplementary plate (material: PLA) that is inserted into the Key Aid Turner (the recess for the key) can be added so that the orientation of the key can be seen even from a distance. There are no accessories. The protruding part of the key is designed as 3 mm x 26 mm.
