Alternatively, in order to stretch various sheet-like curtains used for store decorations and storefront rain protection on fixed construction materials,
It is mainly used by drilling a large number of holes at appropriate intervals in the peripheral end, and passing a rope or the like through these holes and tying it to a fixed structure.

(Problem to be solved by the invention) Since a large number of holes are drilled at appropriate intervals on the circumferential edge of the curtain, the machining is troublesome, and in addition, it takes some time to provide the necessary strength to the circumferential edge. The drawback is that the price inevitably increases due to the processing of the peripheral edge, the selection of materials, and the need to use thick materials.

In addition, in order to install the curtains on the fixed structure, it is necessary to pass the rope through the holes one by one, which is troublesome and time-consuming, and requires a lot of man-hours for installation. It also has the disadvantage that wrinkles form on the surface, and the overall tension is poor, resulting in an unsightly appearance.

(Means for Solving the Problems) The present invention has been made by focusing on the above-mentioned conventional problems, and it is an object of the present invention to solve the problems in the past, and to solve the problem without making a hole in the peripheral edge of the curtain. The above-mentioned problem can be solved by fixing a rod-shaped material with an appropriate diameter by folding back the end and fixing it to a tightening fitting, and by attaching the tightening fitting to a fixed structure and tensioning the curtain. The purpose is to resolve the issue.

The present invention consists of a small circular arc portion formed by curving the tip of one end of the bottom plate upward, and both large circular arc portions formed by cutting the lower part of one end side of both side wall plates that stand upright in parallel on both sides of the bottom plate. and a bolt support plate that stands up at the other end of the bottom plate and has a bolt hole in the center for screwing a bolt, and a rod-shaped material wrapped with a curtain is fitted into the holding part. This is a tightening fitting for a curtain-like object, which is characterized by being inserted and used to tension the curtain-like object.

Further, a board having a required thickness is provided with a holding hole of a required diameter drilled at a required location, an insertion hole cut through the holding hole to one end, and a bolt of a required diameter fixed to the other end. This is a tightening fitting for a curtain-like object, characterized in that the curtain-like object is stretched by inserting a rod-shaped material around which the curtain-like object is wound into the holding hole.

(Function) There is no need to drill holes for attachment at the peripheral edge of the curtain, and the curtain can be stretched to a fixed structure using a tensioning fitting via a rod-shaped material that is folded back and wrapped around the curtain and fixed. Since the curtain-shaped article is easy to process and there are fewer restrictions on materials, the price of the curtain-shaped article can be reduced.

In addition, in order to tension the curtain on a fixed structure, the circumferential end of the curtain is folded back and the rod-shaped material which is fixed by being wrapped around it is hooked to the holding part or the holding hole, and then the tightening fitting is used. Since it is attached to the fixed structure member by tightening bolts, the operation is extremely easy and anyone can do it, and the installation can be done with a small number of man-hours.
