A wing control device is disclosed.
Japanese Patent Application No. 2003-314148. Japanese Patent Application No. 2004-160364.

When the horizontal shielding wing blind is opened, the wing control device needs to maintain the set wing inclination without being affected by wind or the like. For this purpose, the upper holding part for holding the wing holding string of the shielding wings must be firmly fixed so as not to move. However, in the case of a wing operation ring that is held on a cylindrical body that is wound while rotating the heel holding body and performs a tilting operation of the wing with a frictional resistance force due to its gripping force simultaneously with the lifting and lowering operation of the moving heel, Even though the tilt angle range is less than 180 °, the gripping force of the wing operation ring is maintained over the entire rotation range of the cylindrical body being wound and unwound, so It is heavy and causes problems such as accelerated wear of the friction part and the cylinder of the wing operation ring.
In view of the above-described points, the object of the present invention is to provide a wing operation device that normally maintains a set wing inclination and does not give a frictional resistance during the movement operation of the heel. The object is to provide a horizontal shield feather blind that can be operated easily.
Another object of the present invention is to provide a horizontal shielding wing blind provided with a wing operating device with less wear on the friction portion of the operating ring means and the outer peripheral portion of the cylindrical body.

In order to achieve the above object, the present invention provides a horizontal shield wing holding string suspended between an upper wing and a lower moving heel, and a plurality of horizontal shielding wings held on the wing holding string at regular intervals. The upper and lower ends of the wing holding string are coupled to the outer periphery of the wrapping cylinder of the heel band in the upper heel, and the upper end of the wing holding string is coupled to the entire or at least a part thereof. By means of a piece holding means between the gripping opening / closing end and an operating ring means comprising a gripping opening / closing end opened in the axial direction and a gripping force applying means for applying a gripping force of the friction inner peripheral surface, A non-cylindrical opening / closing piece having an operation lever portion that is held movably in the operation direction and extends to an operation cam surface portion adjacent to a part thereof, and an operation cam surface fixedly provided on the heel side around the operation ring means An operation cam is provided, and the friction inner peripheral surface portion provides the gripping force. The cylinder is held by a step with a constant gripping force, and the opening / closing piece grips the friction inner peripheral surface when the shielding blade is tilted toward the lower end and the upper end by the rotation of the cylinder. It is in the wing operation device of the horizontal shielding wing blind that releases the force.

It is also possible to provide a wing operating device that is provided with a non-cylindrical opening / closing piece having an operating lever portion that is held movably in the direction and extends to the operating cam surface in a part thereof.

According to the present invention, the gripping force of the friction inner peripheral surface portion of the operation ring means is released by the opening / closing piece that is operated by the operation cam surface at the end of the movement of the heel when the shield wing is tilted up and down. As a result, a wing operation device can be obtained in which the movement operation of the heel can be performed lightly without giving the frictional resistance of gripping while the movement operation of the heel is continued. At the position where the shield wing is opened at an arbitrary inclination after the movement operation of the heel is completed, the friction inner peripheral surface firmly grasps the cylinder and the operation ring means is fixed on the cylinder. Therefore, since friction during the movement operation of the rod is suppressed, a wing operation device with little wear on the friction inner peripheral surface portion and the outer peripheral portion of the cylindrical body can be obtained.

For the purpose of reducing the resistance of the wing operating device during movement of the heel and making the operation light, the friction inner peripheral surface portion for gripping the cylinder and the grip opening / closing on the operation ring means for holding the wing holding string provided on the cylinder Opening and closing that operates to release the gripping force of the friction inner peripheral surface by an operation cam fixed to the heel side at the end of the front and lower ends of the tilt of the shielding wing between the opening and closing ends of the grip This was achieved by providing a piece.
