Description

The present invention relates to a swing suppressing device for blinds.

Conventionally, there is a blind provided with a swing suppression device for suppressing swing of the lower end of the screen drawn out from the winding pipe. Some conventional rocking suppression devices have a held member provided on a weight bar at the lower end of the screen, which is held by a fixed member fixed to a window frame, wall, or the like. In such a swing suppressing device, the weight bar is held by the holding member by holding the held member by the fixing member, thereby suppressing swinging of the lower end of the screen.

In addition, in the conventional rocking suppression device having such a held member provided on the weight bar, the relative position of the fixed member to the held member varies depending on the position at which the fixed member such as the window frame or wall is fixed. However, there is a type in which the member to be held can be held by the fixed member regardless of the position of the fixed member. For example, a holder that is attached to a weight bar and has grooves extending in the extending direction of the weight bar arranged in a circumferential direction, and a holder that is formed to be attachable to these grooves formed in the holder and can be held by a fixing member. A rocking motion suppressing device having a held member formed in a gap is disclosed (see, for example, Patent Document 1).

In such a conventional rocking suppression device, the position of the held member with respect to the holder is selected by selecting the groove of the holder to which the held member is attached, and the held member is positioned so that it can be held by the fixed member. By doing so, the member to be held can be held by the fixed member regardless of the position of the fixed member.
