<p>A spring loaded rotational pin locking mechanism with a static part (A) which is mounted to the door or other structure and a rotational part (B) which when in an unlocked position can rotate relative to the static part, the static and rotational parts being connected via a central spigot. In use a circular key or disc-shaped key or plate key has a series of pins spread over its surface, for example in a spiral pattern that match up with a series of split pins in the lock. When the correct key is used, the split pins in the lock are aligned with the outer surface of the static part and the rotational part is free to rotate, thus rotating the spigot which is connected to a suitable linkage. Any number of split pins and pins can be used. The advantage of a key with a flat surface and pins protruding is it should be easier to align in the lock and rotate thus particularly useful for disabled or limited sight people or in low light situations.</p> |
