This invention relates to the blind apparatus arrange | positioned at opening parts, such as a window of a building, and for opening and closing this opening part.

The present applicant first proposed a blind apparatus as described in Japanese Patent Laid-Open No. 8-326445.

Such a blind apparatus includes a pair of link mechanisms, a plurality of slat support mechanisms having one end connected to one link mechanism and the other end connected to the other link mechanism, and a slat supported by each of the slat support mechanisms; And a lifting mechanism for raising and lowering the slats, and a tilting mechanism for tilting and shifting the slats by causing a relative position change to a pair of link mechanisms during the raising and lowering of the slats by the lifting mechanism. The arm member which supports the edge part of a slat is provided.

By the way, in the slat support member of the blind apparatus described in the above publication, because the shaft member to which the link member is connected is made of cantilever support, when supporting a plurality of slats, the weight of the slats causes bending of the shaft member, Smooth rotation of the link member in the member may be inhibited, and smooth folding and release of the link member may not be performed.

In addition, in the blind apparatus described in the above publication, since each of the link structures is formed by connecting each of the plate-shaped rigid link members to each other via an axis, a considerable time is required for assembling the link mechanism, and the slats are raised by the weight of the link members. · It requires a great force to descend.

Thus, when a link mechanism is constructed using a belt-like fuselage of a woven or knitted fabric of synthetic resin yarn such as polyester or flexible non-woven fabric of a synthetic resin, instead of a rigid link member, such a belt-like fuselage is used. A slat support member for supporting the slats is also required.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object thereof is to support both shaft members, thereby preventing bending of the shaft members, and to ensure smooth rotation of the shaft members, and to provide a rigid link member. Slat support member suitable for supporting slats with flexible belt-type fuselage, instead of having such slat support members, can be assembled in a short time and light weight, so much force is required to lift and lower the slats The present invention provides a slat support mechanism capable of easily raising and lowering a slat and a blind apparatus provided with the slat support mechanism.
