Claims

[Scope of utility model registration request]

A linkage mechanism is installed inside the guide rails located on both sides of the slats, and multiple stages of slats are supported by the linkage mechanism, respectively, and each slat is opened and closed by lifting and lowering and rotating the slats based on the expansion and contraction of the linkage mechanism. In the shutter, slat holders 17 and 22 supporting each slat 6 are rotatably supported by a linkage mechanism, one end of a tilt arm 25 is connected to each slat holder, and the other end of each tilt arm is connected to a common tilter guide. 30 in a rotatable and slidable manner, the tilter guide is held in the slat horizontal position by a biasing means, and the lower end of the tilter guide is rotated by a tilt lever 34 rotatably supported by the guide rail 2. The lowermost part of the linkage mechanism is connected to a lift truck 43 which is supported so as to be movable up and down within the guide rail 2, and the lowermost part of the linkage mechanism is connected to the lift truck 43, which is supported so as to be movable up and down within the guide rail 2, so that the tilt arm 25 can be rotated based on the rotation of the tilt lever. The cart is made vertically movable by a driving means, and an engagement shaft 37 is protruded from one side of the tilt lever 34, and as the lift cart 43 is lowered, it comes into contact with the engagement shaft 37 and the tilt lever 34 is moved upwardly and downwardly.
A convolutional shutter characterized by rotating 4.
