In addition, the connecting device for a lifting and lowering shoji according to the present invention can be applied to a lifting and lowering window. In this case, the outer frame surrounding the lifting and lowering shoji becomes an opening frame fixed to the building, and a pulley is attached to the opening frame. The frames in the above-mentioned claims are given reference numerals in the drawings for clarity of the relationship with the embodiment, but the present invention is not limited to this.

[0038]

According to the first aspect of the present invention, one pulley and one belt suspend the up-and-down sliding doors on the indoor side and the outdoor side, so that the guide grooves of the outer frame guide the lifting and lowering sliding doors on both sides. It is not necessary to attach a lifting and lowering shoji supporting device to each, so that the structure is simple, the manufacturing cost is low, and only the opening and closing operation of one of the lifting and lowering shojis, the other side of the lifting and lowering sliding interlocking with this Can also be opened and closed. In addition, since the length of the belt can be adjusted only by adjusting one of the belt attachments, the arrangement of the shoji can be made to correspond to the height of the opening with a simple operation. Furthermore, since the indoor sliding door and the outdoor sliding door usually have substantially the same weight, the two raised and lowered sliding doors are naturally balanced at any position in the vertical direction. No need to adjust. Claim
According to the configuration described in Item 2 , the lifting and lowering shoji can be easily attached to and detached from the outer frame, so that the labor required for maintenance and inspection of the raising and lowering shoji and the outer frame can be reduced. According to the configuration of the third aspect, the length of the belt can be easily and quickly adjusted according to the height of the opening simply by turning the adjusting screw.
