barnlås

Barnlås, or barn lock, is a locking device used to secure farm buildings such as barns, stables, granaries, and tool sheds. It encompasses a range of mechanical devices, from simple latches to more complex locks, designed to withstand rural weather and occasional tampering.

Common forms include sliding bolts that engage a bracket or strike plate, and hasps paired with padlocks. Some traditional designs incorporate a lever or mortise lock built into the door. In many older Swedish barns, a large iron bolt is operated from inside, with an exposed padlock or hasp on the exterior to secure the door when closed.

Materials and historical use: Barnlås are typically made of iron or steel, often hand-forged in historic examples. Finishes range from bare iron to painted or galvanised surfaces to resist corrosion. Barnlås were widely used in Sweden and other Nordic regions, reflecting the need to protect livestock, grain, and tools from theft and the elements. As rural security and building standards evolved, newer lock types began to replace older devices, though antique barnlås remain common in farm museums and historic properties.

Maintenance and security considerations: Maintenance involves keeping moving parts lubricated, cleaning debris, and protecting metal surfaces from rust. When used outdoors, weatherproofing and periodic replacement of worn bolts or padlocks enhance security.
