Description

The present invention relates to fittings.

BACKGROUND ART Conventionally, there is known a hanging window that includes a frame, an upper shoji placed on the upper part of the frame, and a lower shoji placed on the lower part of the frame (see, for example, Patent Document 1). In a hanging window, an upper shoji and a lower shoji are fixed to one end and the other end of a suspension rope, respectively, and a middle portion of the suspension rope is wound around a pulley. By moving the lower shoji upward, the upper shoji connected to the lower shoji via the rope moves downward.

Japanese Patent No. 3245318

As mentioned above, in a hanging window, the upper shoji and the lower shoji are connected, so if the length of the hanging rope is too long, the gap between the upper shoji and the lower shoji will open. If the length of the suspension rope is too short, a gap will open between the upper frame of the upper shoji and the upper frame. For this reason, an adjustment member is provided that allows fine adjustment of the length of the suspension rope.
However, since the adjustment member is fixed to the upper shoji and placed in a guide groove that guides the vertical movement of the upper shoji, a screwdriver or the like is required for fine adjustment of the length of the hanging rope after the construction of the hanging window. Difficult to operate.

An object of the present invention is to provide fittings that facilitate the operation of a driver or the like for fine adjustment of the length of a suspension rope.
