Description

Detailed Description of the Invention (Industrial Field of Application) The present invention involves attaching an adsorbing device using permanent magnets and the objects to be adsorbed to both ends of a curtain binding band, and bundling the curtains by the adsorption force, and attaching the adsorbing device to a window opening. The present invention relates to a curtain binding tool which can be attached and detached by means of a locking tool attached to the inside of a pedestal provided in the section, and the band can be replaced or removed at the time of washing with a single touch.

(Prior art) Conventional curtain binding tools have a ring-shaped part at the end of a band, string, etc. that binds the curtains, and the curtains are bundled by passing this ring through a hook attached to a window opening. However, since the ring-shaped part is easily damaged because it is removed from the hook, the applicant has disclosed a device in which the east strap is fixed in the opening by the attraction force of a permanent magnet. In order to prevent this from getting in the way when washing the east belt and causing the suction tool to rust, what should I do? An application has been filed in which suction devices provided at both ends of i'r can be easily removed from the binding band.

(Problem to be Solved by the Invention) However, in the above-mentioned curtain binding device, the suction device attached to the binding band and the other suction device are attached to a window opening such as a window frame.
At least two pairs of suction tools are required, as they are attached to the suction devices attached to both ends of the binding band, and if both ends of the binding band are shifted, Since it is suctioned, the appearance is not neat, and there are also problems such as both ends of the binding band may come off the suction when untying the binding band.
