Description

  The present invention relates to a curtain fabric for roman shade that can be easily attached with a guide ring through which a lifting / lowering cord for raising and lowering the curtain fabric is moved to reduce the manufacturing cost.

  In the conventional Roman shade, for example, a woven fabric or a lace fabric having various designs is used as a curtain fabric, and these are cut into predetermined dimensions. A plurality of ring tapes are fixed by sewing means along the vertical direction on the back surface of the cut fabric body or lace fabric. A plurality of guide rings for inserting and guiding the elevating cord along the longitudinal direction, that is, the vertical direction, are attached to each ring tape at equal intervals. These guide rings are similarly attached to one side surface of the ring tape by sewing means (see, for example, Patent Document 1).

JP 2003-235719 A (paragraph 0012 on page 3-4, FIG. 1)

  However, in the roman shade curtain fabric as in Patent Document 1, a ring tape is prepared for attaching the guide ring, and a plurality of guide rings are attached to one side of the ring tape by sewing means. Furthermore, a plurality of ring tapes to which these guide rings are attached must be sewn along the vertical direction on one side of the fabric body. In this way, a lot of labor is required to sew the guide ring to the ring tape and the ring tape to the fabric body. Not only does it take time, but the cost of these is also high. Therefore, as a result, there is a serious problem that the production cost of the roman shade is very high. In addition, this is one of the problems to be solved in order to widely spread the Roman shade to the world.

  Accordingly, the present invention has been made in view of the above-mentioned problems, and can be easily attached to a side surface of a fabric body without sewing a ring tape, thereby wiping out troublesome conventional work. It is an object of the present invention to provide a roman ciade curtain fabric that can shorten the time and significantly reduce the production cost.

  In order to achieve the above object, a curtain cloth for a roman ciade according to the present invention is a curtain cloth for a roman ciade used in which the cloth body is made of a woven cloth and is suspended from the cloth body. A guide for inserting a plurality of floating yarn portions formed so that a plurality of yarns oriented in the vertical direction along the vertical direction are floated to one side surface as a bundle on the side surface, and a lifting cord is inserted into each floating yarn portion. The ring is detachably attached.

  Further, the curtain fabric of the roman ciade is a roman shade curtain fabric that is used by suspending the fabric body, the fabric body being made of a lace fabric, and a plurality of curtain fabrics in a vertical direction on one side of the fabric body. A plurality of floating yarn portions are formed so that handle yarns facing the vertical direction of the book are floated to one side as a bundle, and a guide ring for inserting a lifting cord is detachably attached to each floating yarn portion. It is characterized by that.

  The shape of the guide ring is selected such that the guide ring is detachably hooked and attached to the floating yarn portion. For example, a guide ring is used that is formed in a substantially S-shape, in which the yarn of the floating part is inserted into the lower space part on the lower side and the lifting cord is inserted into the upper space part.

  When the fabric body is a woven fabric, the curtain fabric of the Roman shade according to the present invention is arranged so that a plurality of yarns oriented in the vertical direction along the vertical direction float on one side of the fabric body as a bundle. A plurality of floating yarn portions to be formed were provided, and a guide ring for inserting a lifting / lowering cord was detachably attached to each floating yarn portion. In addition, when the fabric body is a lace fabric, a plurality of floating yarn portions are formed on one side of the fabric body so that a plurality of handle yarns oriented in the vertical direction along the vertical direction are lifted to the one side. The guide rings for inserting the lifting / lowering cords were detachably attached to the floating portions. As described above, since the float portion for attaching the guide ring to the fabric body is directly formed, the guide ring can be attached only by inserting the yarn of the float portion into the guide ring.

  Therefore, the present invention does not require any troublesome work such as sewing the guide ring to the ring tape or sewing the ring tape along the vertical direction of the fabric body as in the prior art. Is extremely easy to make. Moreover, not only the production time is greatly shortened, but also the production cost can be reduced, which in turn has a great effect on the spread of this kind of roman shade.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of a roman shade curtain fabric according to the present invention will be described below in detail with reference to the drawings. The roman shade shown in this embodiment is of a chain type provided with a winding drum for winding up a lifting / lowering cord. The present invention is not limited to this type of roman shade. FIG. 1 is a rear perspective view of the fabric body according to the present invention, FIG. 2 (a) is a partially enlarged perspective view of the back surface of the fabric body, and FIG. 2 (b) is an enlarged sectional view of the same part. The present invention can be applied to either a woven fabric or a lace fabric as the fabric body. First, a woven fabric, particularly a plain woven fabric will be described.

  The fabric body 1 shown in FIG. 1 is a curtain fabric, and when suspended, warp yarns are woven along the vertical direction, that is, the vertical direction, and the weft yarns are woven along the horizontal direction, that is, the horizontal direction perpendicular to the vertical direction. . And although illustration is abbreviate | omitted, the pattern of various designs is given to the surface of the fabric main body 1. FIG. On the other hand, a plurality of floats 2 are provided at equal intervals in order to attach a guide ring 7 to be described later along the vertical direction on one side of the fabric body 1, that is, the back surface 1a. A plurality of the floating yarn group 3 in the vertical direction is arranged in line with the width of the fabric body 1. Further, a female laminating fastener 4 is fixed along the upper edge of the back surface 1a of the fabric body 1. The female laminating fastener 4 is detachably adhered to a male laminating fastener 23 that is adhered to one side surface of a hanging rod 22 described later. On the other hand, a bag-like portion 5 is formed along the longitudinal direction at the lower end portion of the dough main body 1, and a weight bar 6 for neatly stretching the dough main body 1 so as not to be wrinkled is formed on the bag-like portion 5. Decorated.

  As shown in FIGS. 2 (A) and 2 (B), each of the floating yarn portions 2 causes a part of the warp yarns 2a to fly in accordance with a predetermined vertical width, and only the portions of the float yarn portions 2a are bundled and floated to the back surface 1a side. It is made not to be entangled with the weft 2b. The thickness or number of the warp yarns 2a is selected so that the float 2 has strength against the guide ring 7. As a result, in the floating yarn section 2, a lateral gap S is formed between the plurality of warp yarns 2 a as a bundle constituting the floating yarn section 2 and the fabric body 1. A guide ring 7 to be described later is inserted and attached to the lateral gap S.

  The guide ring 7 is formed of a synthetic resin material, and is formed in a substantially S-shaped plane as shown in an enlarged view in FIG. More specifically, a straight flange portion 8 is provided slightly below the center, and an upper curved flange portion 9a is provided at one end of the straight flange portion 8a. A bent hook part 10 that is bent inward and parallel to the straight hook part 8 is provided at the tip of the upper curved hook part 9a, and an elevator cord 15 described later between the straight hook part 8 and the bent hook part 10 is provided. Is provided with an upper gap 12a for passing through the upper space 11a surrounded by the upper curved flange 9a. On the other hand, the other end of the straight flange portion 8 is provided with a lower curved flange portion 9b having the straight flange portion 8 as a diameter and curved downward and extending in a semicircular arc shape. The tip of the lower curved hook 9b is provided close to one end of the straight hook 8, and the warp yarn 2a of the float 2 is inserted into the lower space 11b surrounded by the lower curved hook 9b in the meantime. The lower gap 12b is provided. On the inner peripheral edge of the lower curved saddle portion 9b, a return piece 13 is provided to project the inserted warp 2a.

  As shown in FIG. 4, the guide ring 7 formed in this way reaches each float 2 on the back surface 1a of the fabric body 1, and a bundle of a plurality of warp yarns 2a in the float 2 is connected to the lower gap 12b. To the lower space 11b. The plurality of inserted warp yarns 2 a are not easily pulled out by the return piece 13. As a result, each guide ring 7 is attached to each floating yarn portion 2 and is positioned orthogonally or horizontally with respect to the fabric body 1 to be suspended. In other words, the surface including the upper space portion 11a is orthogonal to the vertical direction, and the elevating cord 15 is easily inserted. Further, since the plurality of warp yarns 2a are not easily removed by the return piece 13, the guide ring 7 is not unnecessarily dropped off.

  And the raising / lowering cord 15 is inserted in each guide ring group 14 provided with two or more along the up-down direction of the back surface 1a of the fabric main body 1. FIG. The lifting / lowering cord 15 is usually formed longer than the vertical dimension of the dough body 1, but may be, for example, approximately the same as the vertical dimension of the dough body 1 as a minimum dimension. Further, a locking tool 16 is provided at the upper and lower ends of the lifting / lowering cord 15. For example, as shown in FIG. 7, the locking tool 16 is formed by bending a thin wire 17 into an elliptical shape, cutting one of the wires at the substantially central portion and setting one end of the wire 18 as a hooking portion 18. And a fixing plate 19 that is bent so that both ends are wound around each wire 17 is provided at the center of the elliptical wire 17. And the latching | locking part 18 can be engaged with the one hooked part 19a of the fixing plate 19 so that engagement / disengagement is possible. Further, the locking tools 16, 16 at the upper and lower ends of each lifting / lowering cord 15 are inserted and attached to the respective guide rings 7, 7 positioned at the upper and lower ends of the fabric body 1. Thereby, the curtain fabric 20 is completed.

  As shown in FIG. 5, the roman shade 21 is composed of the curtain fabric 20 and a hanging rod 22 for hanging the curtain fabric 20. Next, the hanging rod 22 will be described. Generally, the roman shade 21 is attached to an opening (not shown) of a wall such as an indoor window frame, and the hanging rod 22 is horizontally attached to the upper edge of the opening. The curtain fabric 20 is attached to one side surface (room side) of the hanging rod 22 so as to be detachable. In this case, the curtain fabric 20 is hung with the room side as the front surface and the window side as the back surface 1a, and is formed into a vertically long rectangular shape having a width dimension substantially the same as the length dimension of the hanging rod 22 in the longitudinal direction.

  The hanging rod 22 is made of metal and is formed in a columnar shape having a cross-sectional gate shape having an opening at the bottom as shown in FIGS. 6 to 8, and is formed on one side surface (room side) of the side wall 22a along the longitudinal direction thereof. A male laminating fastener 23 is adhered. On the other hand, the rotation shaft 24 is horizontally arranged in the hanging rod 22 along the longitudinal direction of the center. The rotary shaft 24 has a regular hexagonal cross section, and both end portions are pivotally supported by a pair of bearing portions 25 and 25 attached in the suspension rod 22 so as to freely rotate. Yes. Further, four winding drums 26 are attached to the rotating shaft 24 at substantially equal intervals, and the lifting / lowering cords 15 are wound around the respective winding drums 26.

  As shown in FIG. 7, each winding drum 26 is provided with a mounting piece 28 having a mounting hole 27 on its outer peripheral surface, and the base end side of the auxiliary cord 29 is connected to the mounting hole 27. The length of the auxiliary cord 29 is set to about 2 to 3 times the outer circumference of the winding drum 26, and the connecting ring 30 is attached to the tip portion thereof. In this way, the length of the auxiliary cord 29 is set to a size that is two to three times the outer circumference of the winding drum 26 in order to make it easy to detachably engage the upper end of the lifting / lowering cord 15. This is because the tip needs to protrude slightly from the lower end edge of the hanging rod 22 downward.

  Each winding drum 26 is configured such that the inner peripheral surface of the shaft hole 26 a comes into contact with the outer surface of the regular hexagon of the rotating shaft 24, whereby the winding drum 26 rotates as the rotating shaft 24 rotates. To do. Each winding drum 26 is disposed in a receiving frame 31 fixed to the inner peripheral surface of the suspension rod 22, and cylindrical portions 26 b and 26 b at both ends of the winding drum 26 are bearing recesses 32 and 32 at both ends of the receiving frame 31. It is inserted and supported. In this way, the winding drum 26 is supported by the receiving frame 31 because a large load is applied to the winding drum 26 via the lifting / lowering cord 15 so that the rotating shaft 24 does not bend unnecessarily. It is to make it.

  As shown in FIG. 8, the sprocket 33 is fixed to the end of the rotating shaft 24 outside the one bearing portion 25. A fitting recess 34 is provided around the outer peripheral surface of the sprocket 33, and an endless chain 36 into which a large number of bead-like lumps 35 are sequentially fitted is hung on each fitting recess 34. The sprocket 33 is covered with a cover 37 whose both sides are open, and a chain 36 hung on the sprocket 33 is positioned outside the curtain fabric 20.

  The hanging rod 22 has the above-described configuration, and a curtain fabric is obtained by bonding a female bonding fastener 4 at the upper end of the back surface 1a of the curtain fabric 20 to a male bonding fastener 23 on one side surface (room side) of the hanging rod 22. 20 is hung. Then, the locking tool 16 provided at the upper end of each lifting / lowering cord 15 is removed from the guide ring 7, and the locking tool is fixed to the connecting ring 30 at the lower end of each auxiliary cord 29 with the lifting / lowering code 15 being inserted into the guide ring 7. 16 is locked. In this state, if the chain 36 is rotated forward and backward, the respective winding drums 26 are rotated, and the respective lifting cords 15 are wound or rewound, whereby the curtain fabric 20 is freely folded up and down. .

  In particular, in the Roman shade 21, when the curtain fabric 20 is washed due to dirt, the curtain fabric 20 can be easily detached. That is, as shown in FIGS. 9 and 10, the locking tool 16 at the upper end of the lifting / lowering cord 15 is removed from the connecting ring 30 of the auxiliary cord 29 suspended from each winding drum 26. At this time, the removed locking tool 16 is engaged with the guide ring 7 at the upper end position of the guide ring group 14 as it is. Thus, the upper and lower ends of each lifting / lowering cord 15 do not come off by being locked by the guide rings 7 and 7 at the upper and lower positions via the stoppers 16, and the lifting / lowering cord 15 guides the curtain fabric 20 during washing. The escape from the ring group 14 can be prevented.

  Next, the weight bar 6 is taken out from the bag-like portion 5, and in this state, the female bonding fastener 4 is peeled off from the male bonding fastener 23 to remove the curtain fabric 20 from the hanging rod 22. Then, the curtain fabric 20 is washed with the lifting cords 15 attached.

  After the curtain fabric 20 is washed and dried, the female bonding fastener 4 is bonded to the male bonding fastener 23 of the hanging rod 22, and the curtain fabric 20 is suspended from the hanging rod 22. Further, the weight bar 6 is returned to the bag-like portion 5. Then, as shown in FIG. 10, the locking tool 16 at the upper end of each lifting / lowering cord 15 is removed from each guide ring 7, and again engaged with and connected to the connecting ring 30 of each auxiliary cord 29.

  As described above, the upper end of the lifting / lowering cord 15 is separated from the winding drum 26 side, and the upper end of the lifting / lowering cord 15 is provided with the locking tool 16 that can be detachably engaged with the winding drum 26 side. When removing the curtain fabric 20 from the ridge 22, the curtain fabric 20 can be removed simply by removing the locking tool 16 at the tip of each lifting cord 15. Therefore, the work for removing and attaching the curtain fabric 20 during washing and the installation work in a narrow gap between the window and the curtain fabric 20 can be performed easily and efficiently without taking time.

  The curtain cloth 20 of the roman ciade according to the present invention is formed on the back surface 1a of the fabric body 1 so that a plurality of warp yarns 2a facing in the vertical direction along the vertical direction are floated to the back surface 1a side as a bundle. Since a plurality of portions 2 are provided, and guide rings 7 for inserting the lifting / lowering cords 15 are detachably attached to the respective floating yarn portions 2, the guide rings 7 are simply inserted directly into the guide rings 7. 7 can be attached. Therefore, since the troublesome operation of sewing the guide ring to the ring tape or sewing the ring tape to the fabric body is not required as in the prior art, the production of the curtain fabric 20 is extremely easy. It will be easy. In addition, the production time can be greatly shortened, and the production cost can be considerably reduced.

  Further, in the above description, four rows of the floating yarn group 3 are provided, but this is determined by the dimension between the lateral widths of the fabric body 1, and if the lateral width is increased, the floating yarn group 3 is arranged in five rows and six rows. Try to increase.

  Although the case where the woven fabric is used as the fabric body 1 has been described, for example, a lace fabric may be used as the fabric body. FIG. 11A is a partially enlarged perspective view of a fabric body made of lace fabric, and FIG. 11B is an enlarged sectional view of the same portion. In this case, a floating yarn portion 43 is formed so that a plurality of patterned yarns 42 entangled in the vertical direction along the vertical direction on the back surface 41a of the fabric body 41, which is a lace fabric, floats to the back surface 41a side as a bundle. The guide ring 7 for inserting the lifting / lowering cord 15 is detachably attached thereto. Although detailed explanation is omitted, even with such a configuration, the same actions and effects as those of the fabric body 1 made of the woven fabric can be obtained.
