Description

  The present invention relates to a double elevating curtain device, and more specifically, the raising and lowering of a front curtain and a rear curtain that are opposed to each other by the upper edge portion being attached to a support bar by an elevating operation of an elevating cord. The present invention relates to a double elevating curtain device configured to perform.

  A front curtain and a rear curtain are arranged before and after a straight bar-shaped support bar arranged along the upper edge of the window, and the upper edge portion of each curtain is attached to the support bar. The double elevating curtain device configured to raise and lower the curtain by individually operating the elevating cord attached to each curtain is less expensive than arranging two elevating curtain devices in the front and rear. However, it is popular because it can be configured compactly.

  As shown in FIG. 27, an example of the double elevating curtain device A includes a front locking device b provided corresponding to the front curtain a and a rear locking device d provided corresponding to the rear curtain c. Are provided at different positions in front and back on one end side of the support bar e, and a plurality of lifting cords f attached to the rear surface side of the front curtain a with a required interval in the width direction are gathered together. Passing through the front locking device b, pulling the bundle f1 of the lifting / lowering cords f passing through the locking device b downward, the front curtain a is lifted up, and the lifting / lowering cord f is moved in the required lifting state. By locking, the required pulling state of the previous curtain a is maintained. Similarly, a plurality of lifting / lowering cords h attached to the rear curtain c are put together and passed through the rear locking device d, and the bundle h1 of the lifting / lowering cords h passing through the locking device d is pulled downward. The curtain c can be pulled up, and the raising / lowering cord h is locked in the required lifting state, so that the required lifting state of the subsequent curtain c is maintained.

  If the description of the locking tools b and d is supplemented, the locking tools b and d have the same configuration, and, as shown in FIG. 28, a cord guide portion k for inserting the lifting / lowering cords f and h includes: It is formed between a lower piece n having a rack-like tooth m in the left and right direction on the inner surface of the protrusion, and a roller q rotatably attached to an upper piece p facing the lower piece n, In addition, a pinion-shaped lock roller r is provided on the lower piece n so as to mesh with the rack-shaped teeth m and move left and right. Then, all the lifting / lowering cords are inserted into the cord guide portion k, and as shown in the figure, they are brought into contact with the peripheral surface s of the lock roller r to be inserted laterally. Then, the lifting / lowering cord f or the lifting / lowering cord h inserted in this way is moved by the solid line of FIG. 28 as the lock roller r moves so as to climb the sloped portion t on the left side of the lower piece n. As shown in the figure, the lock roller r and the roller q are sandwiched and locked.

  However, when the double elevating curtain device A having the above-described configuration is used, the plurality of elevating cords f provided on the front curtain a and the plurality of elevating cords h provided on the rear curtain c are in proximity to each other. Since it is in a suspended state, the front and rear elevating cords f and h are liable to be entangled with each other, and there is a problem that it is difficult to accurately perform the elevating operation of the curtain.

  In order to prevent such entanglement of the lifting / lowering cord, as shown in FIG. 29, the front locking device b provided in correspondence with the front curtain a and the rear locking device b provided in correspondence with the rear curtain c Are fixed to both ends of the support bar e, and a plurality of lifting / lowering cords f are attached to the rear surface of the front curtain a with a predetermined interval in the width direction. Then, the front curtain a is pulled up by pulling the bundle f1 of the elevating cord f passing through the front locking device b and passing through the front locking device b downward. While the required pulling state of the front curtain a is maintained by locking f, the rear curtain c is similarly hung at the rear surface side of the rear curtain c with a predetermined interval in the width direction. Elevating installed in the state A plurality of cards h are put together and passed through the rear locking device d, and a bundle h1 of the lifting / lowering cords h passing through the rear locking device d is pulled downward so that the rear curtain c is pulled up. It is also conceivable that the raising / lowering cord h is locked in the required lifting state so that the required lifting state of the subsequent curtain c is maintained.

  However, in such a configuration, the front and rear curtains a and c cannot be lifted / lowered on one side of the support bar e, so that one curtain is lifted / lowered on one end of the support bar and then the other curtain is lifted / lowered. In order to perform the operation, the operator has to move to the other end of the support bar. In particular, when an object such as a dresser is installed on one end side of the support bar, there is a problem that it is difficult to operate the lifting / lowering cord due to the installation object and the lifting / lowering cord cannot be operated.

  Moreover, what is disclosed in Japanese Patent Application Laid-Open No. 2003-93221 has been proposed as a double elevating curtain device for preventing the entanglement of the elevating cord as described above. The double elevating curtain device is provided with a front locking device provided corresponding to the front curtain on one end side of the support bar, and a rear locking device provided corresponding to the rear curtain. A lifting cord provided at a required interval in the length direction of the support bar from the front locking device and hanging down through the front locking device, and a lifting cord in a state hanging down through the rear locking device It was configured to prevent entanglement.

  However, when such a double elevating curtain device is used, it is considered that entanglement of the elevating cords related to the front and rear locking tools cannot be reliably prevented unless the front and rear locking tools are separated by at least about 20 cm. As a result, the lifting / lowering cord that is hung through the locking device after being provided at a predetermined interval inside the support bar is in a position where it enters inward about 20 cm from the side edge of the rear curtain. Because the hanging cord is in a hung state, when the front curtain is pulled up, the lifting cord associated with the rear curtain is in a state of being very conspicuous on the front side of the trailing curtain. There was a problem that greatly deteriorated the appearance of.

  Further, in order to make the rear locking device related to the rear curtain retracted inward from the one end portion of the support bar in this way, the lifting / lowering cord related to the rear locking device is attached to the paragraph of the specification of the patent document. As described in 0029, it is necessary to guide to the subsequent locking device through a guide roller rotatably supported by a support bar. For this reason, there is a problem that the structure for passing the lifting / lowering cord related to the rear curtain through the rear locking device becomes complicated. If the guide structure of the lifting / lowering cord by the guide roller is to be avoided, the lifting / lowering cord for raising / lowering the rear curtain is provided between the side edge of the rear curtain and the rear locking device. Will not be able to place. As a result, when the lifting / lowering cord is lifted / lowered, the trailing curtain is correctly formed with a fold-like folded portion by causing slack in the portion between the side portion of the trailing curtain and the rear locking device. Therefore, it becomes impossible to raise the balance in a balanced manner, resulting in a problem that impairs the aesthetic appearance of the subsequent raised state of the curtain. Therefore, as described above, the lifting / lowering cord related to the rear curtain has to be guided to the rear locking device via the guide roller.

(1) When using the double elevating curtain device according to the invention, since the front and rear locking devices are provided on one end side of the support bar, there is an advantage that the front and rear curtains can be operated on one side of the support bar. The front and rear lifting cords are separated front and back by the front curtain. Therefore, unlike the conventional double elevating curtain device in which the front and rear elevating cords hang down between the front and rear curtains, the front and rear elevating cords can be prevented from being entangled with each other. It can be done reliably.

(2) In order to adopt a configuration in which the front elevating cord is separated by the front curtain by hanging the front elevating cord on the front side of the front curtain through the insertion part provided in the front curtain, Unlike the case of the conventional double lifting curtain device in which the front and rear lifting cords are prevented from being entangled by shifting the position left and right between the curtains, the front lifting cord is close to the side edge of the previous curtain. Can be hung on the front side of the previous curtain. Therefore, even if the front lifting / lowering cord is hung on the front side of the front curtain, there is no risk of unnatural appearance of the curtain.
Further, since the front lifting / lowering cord hangs in the vicinity of the side edge of the previous curtain in this way, the lifting / lowering cord is connected to the inner side through the guide roller as in the conventional double lifting / lowering curtain device. The double elevating curtain device can be configured with a simple structure without the structural complexity of having to guide to the locking device located at the position, and the front and rear elevating cords are less likely to get tangled.

(3) The operation cord is connected to the lower end of the lifting / lowering cord that is inserted through the insertion portion provided in the previous curtain and hangs down on the front side of the previous curtain via a knob, and the lower end of the operation cord is When adopting a configuration that is attached to the lower edge of the previous curtain, just below the insertion part, the previous lifting cord hanging from the front side of the previous curtain is constant from the side edge of the curtain over the entire vertical length. Since the distance is separated, there is an advantage that the front and rear elevating cords do not approach even when the front curtain is pulled up.

(4) When the insertion part provided in the front curtain is provided above the lower end of the fold-back part of the folding surface part in front of the fold-back part, the fold-back is provided above the insertion part. Since no part is formed, there is no possibility that the formation of the fold-like folded part will be hindered by the frictional resistance caused by the lifting cord passing through the insertion part, and all the fold-like folded parts can be formed correctly. .
