| 摘要 |
The door leaf has conical steel lugs, or other strip-securing elements, protruding from the hinge strip side. On closure, these engage holes in the door frame, or in wear-resistant reinforcing units inserted in these. These elements are located on a rail (6), or similar, made of metal or other firm material, extending virtually over the door leaf's (4) full height. The rail is inlaid and fixed in a continuous groove (7) in the leaf, or in its rebate. A series of securing elements may be fastened at intervals on a rail, which pref. has sunken holes for fixing screws. ADVANTAGE - The system can be easily and quickly mounted, with no need for precise cutting.
