Abstract

See full text

A patch fitting for a glass door includes a mount for being mounted on a floor, a shaft connected with the mount, a clamping seat pivotally connected with the shaft, and a piston unit installed inside the clamping seat. When the glass door is sweeping to open or close, the clamping seat will turn along with the sweeping movement of the glass door about the shaft and the piston unit will be pushed by an eccentric cam of the shaft to press the hydraulic oil contained in the clamping seat so as to provide a damping resistance in response to the sweeping movement of the glass door. The patch fitting can be easily installed on the floor by a simple work.
