Improvements in and relating to multifold door and window assemblies

摘要

A multi-fold leaf (30, 31) joinery assembly has a joinery bogey unit (2) that is pivotally connected to a joinery leaf. A seal (20) is provided on a moveable edge of the leaf adjacent to the bogey unit, the seal being adjacent to a frame seal (25) for a head or sill of a frame of the assembly when the at least one leaf is in a closed position. The pivot connection is off-set so that the seal moves away from the frame seal when the leaf is opened, thus avoiding scrubbing.
