Abstract: The present invention is related to an auto-return apparatus of a glass door, comprising a clamping base, a damper and a misalignment adjuster. The clamping base is secured onto the glass door and comprises a securing axle. The securing axle comprises an eccentric cam and the damper is received within the clamping base and abuts the eccentric cam of the securing axle to provide resisting force for door opening and closing. The misalignment adjuster comprises a moving plate and a securing means. The moving plate comprises a long slot provided for the securing means to pass therethrough and a mounting slot provided for the securing axle to be connected thereto such that the moving plate moves together with the clamping base along the extending direction of the long slot and relative to the securing means in order to achieve the objective of adjusting misalignment of the glass door.

Abstract: 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.

Abstract: A patch fitting with auto-return function for a glass door includes a clamping seat, a damper and a misalignment adjuster. The clamping seat is adapted for clamping and being mounted on the top edge of the glass door and comprises a shaft body and an eccentric cam connected with the shaft body. The damper is installed in the clamping seat and contacted with the eccentric cam. The misalignment adjuster comprises a mounting plate, a plurality of adjustment members and an adjustment plate. The mounting plate has a concave space and a plurality of adjustment holes communicated with the concave space. Each of the adjustment members is disposed in each of the adjustment holes. The adjustment plate is arranged in the concave space of the mounting plate, connected with the shaft body and stopped by at least one of the adjustment members.
