Claims

[Scope of Claim for Utility Model Registration] (1) A corner joint consisting of left and right joint cases that are removably fitted to left and right curtain rails, and a connecting member that connects the left and right joint cases so that they can rotate relative to each other. The coupling member includes a box-shaped center case that is open on the left and right sides and has a lifting cord hole in the center of the bottom, a forked portion that protrudes from the center case to the left and right, and a forked portion that rotates symmetrically inside the center case. Consisting of two freely arranged horizontal guide rolls, each joint case has a fork protruding from the curtain rail, and the joint case fork connects to the center case fork through a vertical pin. is rotatably connected to
A Roman shade corner joint for a bay window, characterized by a vertical guide roll rotatably fitted onto each vertical pin. (2) The scope of the utility model registration claim characterized in that the two horizontal guide rolls are arranged so that the upper surface of their envelope surface is the same as or slightly lower than the vertical bisector of the center case. A Roman shaded corner joint for a bay window as described in item 1. (3) The joint case fork and the center case fork should be closer to the front of the center, and the outer circumferential surface of the vertical guide roll should be in contact with the front and rear bisectors of the center case or be located a little further forward than that. A Roman shaded corner joint for a bay window as set forth in claim 1 of the utility model registration claim, which is characterized by:
