Description

In the present invention, a belt or wire is looped in a rail, and a curtain provided with a leading runner connected to the belt or wire is used. The present invention relates to a curtain opening/closing device for automatically closing or opening a closed curtain.

For example, a curtain opening/closing device that uses a spiral spring to wind a wire installed between a window frame or curtain rail of a building and a side-opening curtain semi-automatically opens and closes the curtain with a reel that uses a spiral spring. Japanese Patent Application Laid-Open No. 2002-300003 discloses a method for performing this. The curtain opening/closing device described in Patent Document 1 is of a type in which one curtain opening/closing device opens and closes one curtain, and includes an opening/closing reel device for winding a long body such as a string, rope, or belt by the action of a spiral spring. It is a device that semi-automatically opens and closes one curtain by attaching a connection part (hanging tool) that links one curtain and a long body to the curtain. In this curtain opening/closing device, when one curtain is closed, the free end of the elongated body is pulled down to move the connecting portion to close the curtain. When the elongated body is wound up by the force of the flat spiral spring, the connecting portion moves the curtain, thereby opening the curtain.

Further, the curtain opening/closing device disclosed in Patent Document 1 can simultaneously open and close a pair of left and right curtains by a single curtain opening/closing device. That is, a curtain opening/closing device is arranged over almost the entire length of the curtain rail, and for example, a pair of left and right curtains is semi-automatically opened and closed by an opening/closing reel device using a spiral spring arranged at the left end. The elongated body such as the curtain rail is folded back by the folded part at the other end of the curtain rail and suspended from the guide part. The curtain automatically opens when the long body is wound up by the force stored in the spiral spring.

More specifically, in the curtain opening/closing device described in Patent Document 1, a long body such as a string or wire rope is attached to one end (the left end in this example) of a curtain rail 24 extending in the left-right direction as shown in FIG. An opening/closing reel device 21 is provided for winding a curtain rail 22 onto a reel by the action of a built-in spiral spring, and a folded part 25 of the long body 22 is arranged on the other end side of the curtain rail 24 and provided on the long body 22. The curtain 20 is attached to the connecting portion 26, and the free end side of the elongated body 22 is folded back at the folding portion 25 arranged at the other end side of the curtain rail 24, and the guide portion 28 provided at the left end of the curtain rail 24. It hangs down from a horizontal state to a vertical state through the Reference numeral 27 denotes a gripping portion for the elongated body 22 always suspended from the guide portion 28 .

In the case of the curtain opening/closing device having such a configuration, when the long body 22 always hanging down from the guide portion 28 is grasped by the grasping portion 27 and pulled against the spiral spring of the opening/closing reel device 21, the long body 22 is drawn out. The curtain 20 is closed by the opening and closing reel device 21, and the curtain 20 opens when the long body 22 is taken up by the opening and closing reel device 21 by the action of the spiral spring of the opening and closing reel device 21. The body 22 always hangs down on one end side of the curtain 20 and is exposed to the eyes of the user. There are problems such as the risk of injury due to the swinging of the long body and the damage to the glass door and the inner wall of the room.

In addition, behind the leading runner 5-1, shielding material hangers (runners) 7 for suspending the shielding material 6 are aligned in number according to the length of the shielding material rail 1. As shown in FIG.

FIG. 5 shows a drive system that combines the opening/closing operation device 3 and the drive device 4 to rotate the elongated body 2 in its longitudinal direction.
The opening/closing operation device 3 operates a built-in clutch mechanism 3-3 by "pulling" and "returning" the operation cord 3-2 to rotate the elongated body 2 and to open and close the loop on the opening/closing operation device side. The reel 3-1 can be idled and stopped, and the elongated body 2 can be moved and stopped. The operation of the clutch mechanism is connected to the clutch mechanism 3-3 and utilizes the power of the "string pull-back spring 3-4" that serves as its drive source. When the operating string 3-2 is pulled, the clutch mechanism The clutch is activated, and when the operation string 3-2 is returned, the clutch is released and the opening/closing operation device side loop reel 3-1 idles.

On the other hand, the drive device 4 incorporates a drive spring 4-2 that serves as a drive source for rotating the elongated body 2, and its force accumulation is performed by the rotation of the elongated body 2 accompanying the opening and closing operations of the shielding member 6. It is Reference numerals 4-4A and 4-4B denote drive device cases that can be separated into upper and lower parts for housing the drive springs. (See Figure 6.)
In the driving device 4, a driving device-side loop reel 4-1 for rotating the elongated body 2 is attached to the shaft of the driving spring.
