A hinge for a door such as a conservatory comprises a first part 12 with rear surface 20 for positioning against a frame. A hinge pin 26 extends from the first part to which a second part 14 is pivotally mounted. A central axis of the pivot 26 is spaced at least 30mm from the rear surface 20 and co-operating locking means are provided for locking the first part to the second part in at least one open position. The locking means may be a projection 28 on hinge pin 26 which cooperates with axially movable collar 36; alternatively a recessed pocket in pin 26 may cooperate with an axially moving protrusion on the second part14. The hinge lock may be biased into the open position and provided with a button for operation. Indexing detents 32 may be provided for locating the hinge at predetermined positions. Spacing the hinge pin from the mounting surface enables the door clearance of the frame and achieve greater than 90 degree opening. |
