Door frame bearing and components

摘要

The bearing bolt (1) is mounted adjustably on the top or bottom of the door to engage a hold (8) provided for the bolt in a bearing part (7) which can adjust relative a slot (6) provided in the door frame stringer (5). The bearing part (7) is angular in section and can adjust along the stringer (5), and the vertical leg (10) of the part (7), when operating, is slotted out (11) for an e.g. screw used to secure the bearing part to the stringer (5). The bearing part face conforms to the shape of the stringer section it faces and the part can be closed off by a cover cap which is also slotted out to open inwards for the bearing bolt.
