<p>A butt flag hinge 1 has a packer 15 retained by, integrated with, or built into, at least one of the hinge flag leafs 3 and is adjustable in the lateral direction. The flag leaf 3 may have stepped construction 7, 8 connected by a vertical strip 9, to fit into a longitudinally extending groove in a door or window profile. The packer 15 may be retained by means of screws 20 turnable through threaded holes to move the packer 15 in or out 29. The packer 15 may be housed in a channel in the leaf 3, and may move in and out of the channel when adjusted. C shaped clip washers may be provided behind the retaining screws 20. The packer 15 may be a rectangular metal plate and the hinge flag leafs 3 may be PVC-U. The hinge 1 allows adjustment of a hinged door or window without dismounting it entirely, for example in the event of thermal expansion.</p> |
