PROBLEM TO BE SOLVED: To solve a problem that conventional protection screens are connected to each other by drawing cords through their holes and tying them together and, therefore, the cords are cut and discarded when the length of the cords is adjusted or the cords are removed. SOLUTION: The cords drawn through the holes of the protection screens are held by hand, and a body is placed from below. Then the cords are brought together at a position of a guide pin, and are tightened up. The remaining cords are passed to the left side of a support. When a finger-putting part of a rotation claw also is turned clockwise by a fingertip, a key-shaped claw also is turned in the same direction, so as to push and fix the cords. When the length of the cords is changed or the binding is released, the cords are disengaged from the key-shaped claw by turning the key-shaped claw counterclockwise. COPYRIGHT: (C)2011,JPO&INPIT
