A rolling hinge 30 for a sliding and pivoting wing comprising a wheeled bogey 32 having an upstanding hinge pin received within an aperture of a hinge member 34. Wheeled bogey having a first bearing surface 36 bearing against hinge member. A detent 40 protrudes from the bogey over the first bearing surface between which is located a tang 38 of the hinge member formed by radially protruding surface of the bearing surface of the hinge member; the protruding tang and detent prevent axial separation of the hinge from the bogey at least in one rotational position. When the wing is rotated open, e.g. perpendicular to the sliding direction, the tang may no longer be blocked by the detent and allows removal of the door from the frame. When the door is initially pivoted open the tang may prevent detachment of the door as it is slightly tilted to release the guide at the opposite end. Claims are also directed to a sliding block and safety device; a sliding and swinging wing with track engaging extension member and spring loaded latch; magnetic wing fixing system; and sliding hinge. |
