RIM LOCK Meaning and
Definition
-
A rim lock is a type of mechanical door lock that is installed on the surface of a door, rather than being set into the door like other types of locks. It is typically used on older doors or doors that require additional security.
The construction of a rim lock consists of a metal casing, usually made of brass or steel, which contains the lock mechanism. This casing is attached to the surface of the door, with the lock bolt extending out of the casing to secure the door in place. The lock is operated by a key or a knob, both of which control the bolt's movement.
Rim locks are known for their simplicity and durability. They are relatively easy to install and do not require any special modifications to the door itself. The design also allows for easy maintenance and repair, as the lock mechanism can be accessed by removing the casing.
Due to their historical association and antique aesthetic, rim locks are sometimes chosen for decorative purposes in older homes or buildings. However, they are still widely used today for their practicality and security features. Rim locks provide a reliable way to lock a door and are typically seen as a reliable deterrent against unauthorized entry.
Etymology of RIM LOCK
The word "rim lock" is composed of two separate terms: "rim" and "lock".
The term "rim" originated from the Old English word "hrim" which means "edge" or "border". It has Germanic roots, deriving from the Proto-Germanic word "hrimaz". Over time, the word evolved into the Middle English "rimme" and eventually became "rim" in Modern English. In the context of a lock, "rim" refers to the external or visible part of the lock mechanism.
The term "lock" has its origins in the Old English word "loc" which means "fastening device" or "barrier". It goes back to the Proto-Germanic word "lukan" which meant "to close" or "to lock".
