oviliitosten

Oviliitosten is a term used in Finnish carpentry and architectural terminology to describe the joints and connections that secure a door to its surrounding structure, including the door leaf, the frame, and related hardware. The expression typically covers the various interfaces where the door meets the frame, as well as the points where hardware such as hinges, locks, and strikes are attached.

In practice, oviliitosten encompass the methods and components that make a door functional and durable. This includes hinge mortises and insertions, screw-fastened ties between the door and frame, and traditional joinery such as mortise-and-tenon or dowel joints used in timber door construction. The aim of these joints is to provide proper alignment, allow for smooth rotation of the door, and bear the structural loads from use, weather, and opening forces.

Common types of door joint interfaces include hinge connections (ranging from butt hinges to continuous or pivot hinges), frame-to-door connections created by mortise-and-tenon or other joinery, and the hardware interfaces where locks, latches, and weatherstripping are attached. The choice of joints and materials depends on factors such as door weight, climate, fire ratings, and desired aesthetics.

Materials used for oviliitosten can be wood, metal, or composites, often combined to balance strength, durability, and ease of maintenance. Regular inspection and maintenance—checking alignment, lubrication of hinges, and replacement of worn fasteners or hardware—help preserve the integrity of door joints over time.
