In the mounting device described in the above publication, in order to mount the slat hanger to the hook, it is necessary to pull down the mounting portion of the slat hanger from above the opening of the hook that opens upward, and engage the mounting portion with the hook. . However, the hanger rail of the vertical blind is fixed to the upper part of the window, and the hook provided at the lower end of the slat suspension shaft of the runner slightly protrudes downward from the hanger rail. Then, the work of guiding and lowering the mounting portion of the slat hanger above the opening of the hook at such a high position is complicated.

In order to remove the slat hanger from the hook, it is necessary to lift the slat hanger upward from the opening of the hook. Therefore, the work of attaching and detaching the slat hanger was complicated.

Further, since the hook is formed of a thin metal plate, if the slat is pulled strongly downward, the hook may be elongated and the slat hanger may fall off. In the mounting device described in JP-A-4-7489,
The hook is opened to the side, and the mounting portion of the slat hanger is formed in a frame shape. Then, to attach the slat hanger to the hook, insert the hook into the attachment portion of the slat hanger, guide the hook shaft provided on the attachment portion from the side of the hook to the opening of the hook, and pull down further. There is a need. When the slat hanger is detached from the hook, the reverse operation is required. Therefore, the work of attaching and detaching the slat hanger was complicated.

An object of the present invention is to provide a slat hanger mounting device which has sufficient strength and is easy to attach and detach.

[0008]

In order to achieve the above object, the present invention provides a vertical blind in which a slat is suspended and supported via a slat hanger on a slat suspension shaft of a runner moving on a hanger rail. The lower end of the slat suspension shaft is formed in a forked shape from a support piece and a guide piece, the guide piece is provided with flexibility, and the support piece has a protrusion protruding toward the guide piece. The slat hanger is formed with a hook shaft that can be inserted between the support piece and the guide piece, and the protrusion has a support recess that can support the hook shaft. The interval between the portion and the guide piece is set to be smaller than the thickness of the hanging shaft.

The support piece is shorter than the guide piece.

[0010]

When the latch shaft of the slat hanger is applied between the support piece and the guide piece and pressed upward, the guide piece is bent,
When the hanging shaft is guided to above the protruding portion and the slat hanger is pulled down from that state, the hanging shaft is supported by the support recess, and the slat hanger is suspended and supported by the slat suspension shaft.

When the slat hanger suspended and supported by the slat suspension shaft is lifted upward and inclined, and then lowered in this state, the slat hanger is detached from the slat suspension shaft.

Since the support piece is shorter than the guide piece, the slat hanger can be easily tilted.
