Patent ID: 8449003

Claim:
A door expansion adjusting handle and latch set for mounting on a door, comprising: a first handle positioned on a first side of a door having a thickness; a shaft having two ends, wherein the first handle is fixedly connected to one end of the shaft; a second handle which is positioned on a second side of the door to the other end of the shaft by a fixing member, the fixing member 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 biasing member that is interposed between the fixing member and the second handle to take up any changes in the thickness of the door and which automatically biases the first handle and the second handle towards each other without any need for a user to make further adjustments of a position of the fixing member on the shaft, wherein if the thickness of the door increases, the biasing member will automatically permit the second handle-to move closer to the fixing member to increase a working length of the shaft between the first and second handles, and if the thickness of the door decreases, the biasing member will automatically permit the second handle to move further from the fixing member to decrease a working length of the shaft between the first and second handles.
