A door panel (2) comprises an external sheet (l0), an internal liner sheet (ll), and an insulting core (12) therebetween. The sheets (10, 11) are insulated from one another. Each panel (2) has two ends with different profiles. The internal liner sheet (ll) has a hinge receiver (20) on one edge defining a recess (21) for receiving a barrel (23) of a conventional hinge (3). The hinge (3) has an upper leaf (25) which is screwed to the liner (11) of an upper panel (2) and a lower leaf (26) which is screwed to the liner (11) of a lower panel (2). The hinge receiver (20) comprises a lower portion (30) which extends in the direction of the external sheet (10) and a return leg (31) which extends towards the inside of the door panel. The leg (31) extends generally perpendicular to the plane of the inside of the door panel to correctly locate the hinge (3), on assembly. The leg (31) has a downturned formation (32) which engages, on assembly with the barrel (23) of the hinge (2) for alignment of the hinge barrel (23) in the hinge recess (21). The lower portion (30) of the hinge receiver in this case has a bend (35) between a first entry section (36) and a second section (37) extending to the return leg (31). The entry section (36) extends at an angle alpha of approximately 55 DEG ; with respect to the inside face of the liner sheet. The hinge receiver ensures that a hinge (2) is located precisely whilst allowing adjacent panels (2) to butt together for precise location of the panels (2), on assembly. This ensures that the correct geometry at the joint between the panels (2) is maintained as the door opens. The liner arrangement (10, 11) ensures that there is a close fit at the inner joint, when closed, to prevent entry of fingers, and that as the door opens, the gap remains sufficiently tight to prevent finger entry. |
