Zasuwkowy

Zasuwkowy is a Polish adjective used to describe devices, mechanisms, or systems that operate with a sliding bolt (zasuwka) as the main locking element. The term is common in locksmithing, carpentry, and architectural hardware, where a mechanism secures a door, gate, or other closure by moving a bolt into a receptacle.

Linguistically, zasuwkowy is formed from the noun zasuwka, meaning a bolt or latch, with the adjectival suffix -owy, which signals relation or belonging. As such, it designates the characteristic or function of using a sliding bolt.

In practice, the label zasuwkowy is applied to locks, hardware fittings, or structures that rely on a sliding bolt to secure or release. A typical example is a zasuwkowy zamek, or sliding bolt lock, in which a bolt moves horizontally to engage a strike plate or keeper. The mechanism is usually simple and robust, and variants may include springs or manual operation. Zasuwkowe elements are commonly found on interior doors, garden gates, storage chests, and wooden shutters, among other applications.

See also: zasuwka, which refers to the bolt or latch itself, and to related lock types and hardware terms used in Polish locksmithing and carpentry. The term emphasizes the motion and function of a sliding bolt as the primary means of securing an enclosure.
