CHAIN LOCK Meaning and
Definition
-
A chain lock is a type of lock that consists of a chain and a locking mechanism, commonly used to secure doors. It is typically installed on the interior side of the door and provides an additional layer of security, allowing the door to be partially opened while still remaining locked and preventing unauthorized entry.
The chain itself is usually made of strong and durable materials such as steel or brass, which makes it resistant to cutting or breaking attempts. One end of the chain is securely attached to the door frame, while the other end is fastened to a small plate or catch that is connected to the door. The locking mechanism is located on this plate and is typically made up of a pivoting or sliding bar that can be engaged or disengaged to open or close the chain.
The purpose of a chain lock is to provide a means of communication and verification before fully opening the door. When engaged, it allows the door to be partially opened, allowing the person inside to see and identify the visitor before deciding whether to grant full access or keep the door secured. This can help enhance personal safety and security, particularly in situations where individuals may feel vulnerable or uncertain about unexpected visitors.
Chain locks are commonly found in residential homes, hotels, and other buildings where privacy and control over access are important concerns. Additionally, they can serve as an added security measure when used in conjunction with other door locks, such as deadbolts or knob locks.

Etymology of CHAIN LOCK
The word "chain lock" is a combination of two separate words: "chain" and "lock".
The term "chain" traces back to the Old English word "cæcen", which originally meant a series of connected links. It is related to the Old Norse word "keðja" and the Old High German word "chein", all with similar meanings. Over time, the word evolved and became used to refer to various linked objects, including the metal chains often used for security purposes.
The word "lock" comes from the Old English word "loc", which meant a fastening device or barrier. It is derived from the Proto-Germanic word "lukaz" and is related to the Old High German word "loch" and the Old Norse word "lok". In general, a lock is a mechanical or electronic device designed to prevent unauthorized access and secure something.
