Abstract
A door expansion adjusting handle and latch set for mounting on a door. It includes a first handle positioned on a first side of a door having a thickness, a shaft having two ends with one end fixedly connected to the first handle, a second handle positioned on a second side of the door and connected to the other end of the shaft by a nut, the nut permitting the second handle and shaft to rotate relative to each other but preventing the second handle from being removed from the shaft, a latch that is operated by rotating the first handle and/or the second handle, and a coil spring that is interposed between the fixing member and the second handle to bias the first handle and the second handle towards or away from each other. If the thickness of the door increases or decrease, the coil spring will permit the second handle to move closer or further from to the fixing member to accommodate the increase in door thickness.
