Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to a slat hanger attachment device for a vertical blind.

[Conventional technology]

Conventionally, in a vertical blind, a large number of slats are suspended and supported via slat hangers from a runner that moves within a hanger rail, and each slat hanger is suspended and supported so as to be rotatable in a horizontal direction with respect to the runner. An example of such a slat hanger attachment device for vertical blinds is the one described in Japanese Utility Model Publication No. 63-21675. That is, as shown in FIG. 6, a vertical shaft 21 made of synthetic resin that hangs down from the runner body is provided with a gap 23 opening at the front of the vertical cross section and a hook portion 25 having a lower jaw 24 at the bottom. A hole 27 that engages with the hook portion 25 is formed in the slat mounting plate 22 made of synthetic resin, and an insertion portion 28 is formed above the hole 27.
is formed. Further, a protrusion 26 is provided on the front upper edge of the lower jaw 24 of the hook portion 25, and the vertical interval between the holes 27 is narrower than the vertical thickness of the lower jaw 24 including the protrusion 26. It is formed so that it is wider than the thickness not including it. Then, the insertion portion 28 of the slat mounting plate 22 is inserted into the gap 23 of the vertical shaft 21, and the insertion portion 28
When the slat mounting plate 22 is rotated downward while the upper edge is in contact with the upper surface of the gap 23, the upper edge of the hole 27 is brought into contact with the protrusion 26.
The hole 27 elastically overcomes the hook part 25 and engages with the hook part 25,
This allows the slat mounting plate 22 to be fixed to the vertical shaft 21.

There is also one described in Japanese Utility Model Publication No. 58-40236. That is, as shown in FIG. 7, a hook-shaped hanger 3o is provided at the lower end of the hanger shaft 29 hanging from the runner body, and a hole 32 is formed in the wing plate 31. The wing plate 31 can be supported on the hanger shaft 29 by hooking the hole 32 of the wing plate 31 onto the hanger 30.

[Problem to be solved by the invention]

However, in the mounting device described in Japanese Utility Model Publication No. 63-21675, the engagement state between the hole 27 of the slat mounting plate 22 and the hook portion 25 of the vertical shaft 21 is only maintained by the protrusion 26 formed on the hook portion 25. Therefore, if the slat mounting plate 22 is tilted due to shaking of the slat, etc., there is a risk that the upper edge of the hole 27 in the slat mounting plate 22 will climb over the protrusion 26 of the lower jaw 24, and as a result, the connection between the hole 27 and the hook portion 25 may The slat mounting plate 22 is disengaged and the vertical shaft 21
There is a problem with it falling off. Further, since the vertical distance between the holes 27 is formed to be wider than the thickness of the lower jaw 24 not including the protrusion 26, the upper edge of the hole 27 gets over the protrusion 26 and the hole 27 reaches the hook portion 25. In the engaged state, a gap G is created between the lower surface of the lower jaw 24 and the upper edge of the hole 27, so there is also the problem that light leaks through the gap G.

Also, in the mounting device described in Japanese Utility Model Publication No. 58-40236, the wing plate 31 is only supported on the hanger shaft 29 by hooking the hole 32 of the wing plate 31 onto the hanger 30, so that the hanger 30 is There is a problem in that a gap G is created between the lower surface and the lower edge of the hole 32, and light leaks.

This invention was made to solve the above problems, and its purpose is to provide a slat hanger mounting system that can stably support the slat hanger on the runner and prevent light from leaking from the mounting part. The goal is to provide equipment.
