摘要

The arrangement is for a set of ironmongery fittings is for a wing rebate and opening of a door or window, with a connecting rod, socket and swivelling bolt. The socket (8) opening is in the surface section next to the wing opening periphery. The coupling blade (102), from the bolt (10) outwards, extends in a slit parallel to the wing plane, into the wing opening. The coupling plate (39) extends through a second slit (27) across the first, where the plate is slotted (40) for blade passage. The plate is held on the rod to move across its longitudinal axis.
