Description

  The present invention relates to a pleated screen including a honeycomb-shaped screen main body having an upper end attached to a head rail and a bottom rail attached to a lower end, and the screen main body is configured to be foldable.

  Conventionally, a screen material is formed while a plurality of mountain folds and valley folds are alternately arranged in a direction orthogonal to the direction in which these folds extend, and is fixed to one end in a direction orthogonal to the direction in which the folds of the screen material extend. A pleat in which a box is fixed, a movable rail is fixed to the other end in a direction perpendicular to the direction in which the screen material folds extend, and a pull-out end of an opening / closing cord that is pulled out from the fixed box is connected to the movable rail A screen is disclosed (for example, see Patent Document 1). In this pleated screen, the screen material has a plurality of insertion holes through which the opening / closing cord is inserted, and the screen material is shortened while the mountain folds and valley folds are folded by pulling the opening / closing cord into the fixed box. By pulling out from the fixed box, the screen material is lengthened while the mountain and valley folds are opened. The screen material includes first and second screen materials arranged at a predetermined interval between each other. These first and second screen materials both have a plurality of high fold regions that form relatively high mountain folds and a plurality of low fold regions that form relatively low mountain folds. The high fold region and the low fold region are alternately distributed with respect to a direction orthogonal to the direction in which the fold extends. Furthermore, the vicinity of the ridge line of the mountain fold in the high fold area of the first screen material and the vicinity of the ridge line of the mountain fold in the high fold area of the second screen material appear to overlap each other when viewed in a direction orthogonal to the direction in which the fold extends. The insertion hole is provided in the vicinity of the ridgeline of the mountain fold in the high fold region of each of the first and second screen materials.

  In the pleated screen configured as described above, an air layer is formed at a predetermined interval between the first and second screen materials, so that a pleated screen having a high heat insulating effect can be obtained. Further, by forming the first screen material and the second screen so that the material, color tone, crease formation mode, and the like are different from each other, a wide variety of products can be achieved. Further, when the pleated screen is manufactured, it is not necessary to join the first and second screen materials in advance, that is, the first screen material and the second screen material are separately assembled at the manufacturing stage of the pleated screen. Therefore, it is possible to quickly respond to various demands regarding the material, color tone, crease formation mode, etc. separately for the two screen materials without complicated inventory management. Further, since the insertion hole for inserting the opening / closing cord is provided in the vicinity of the ridge line of the mountain fold overlapping each other in the high fold region of each of the first and second screen materials, the opening / closing cord can be used to unfold the screen material or In addition to the function of folding, the first and second screen members are also connected to each other. As a result, a special part for connecting the first and second screen materials to each other is not necessary, and an increase in the number of parts can be suppressed. Furthermore, since the mountain folds in the low crease region of each of the first and second screen members are seen so as not to be located at the portion where the insertion hole is located when viewed in a direction perpendicular to the direction in which the folds extend, The work of inserting the opening / closing cord into the hole is facilitated, and interference between the mountain fold and the opening / closing cord in the low fold region can be avoided.

  On the other hand, a pleated fabric that can be bent in a zigzag is suspended and supported from the head box, a weight bar is attached to the lower end of the pleated fabric, and the weight bar is lifted and lowered by a lifting cord suspended from the head box. A pleated curtain that expands and contracts is disclosed (for example, see Patent Document 2). In this pleated curtain, every other fold of the pleated fabric is provided with a connecting piece that protrudes in the horizontal direction over the entire area of the fold, and an elevating cord is inserted into this connecting piece. In addition, the connecting piece is attached to the tape at the both ends connected to the head box and the weight bar at equal intervals, and the tape is placed at a position facing the pleated fabric across the lifting cord inserted through each connecting piece. Provided. Further, the connecting piece is formed by overlapping and attaching the pleated fabrics, stitching the base ends of the connecting pieces, or bonding the connecting piece separate from the pleated fabric to the crease portion.

  In the pleated curtain configured as described above, the elevating cord is hidden by the pleated fabric and the tape to prevent its exposure, and the folds are maintained at equal intervals by the tape while the pleated fabric is lowered to the lower limit. In this way, since it is possible to prevent exposure of the lifting / lowering cords and uneven crease intervals with a simple configuration and low cost, the aesthetics of the pleated curtain can be improved.

  On the other hand, a fiber honeycomb structure in which left and right fiber pleat screens are connected by a fiber joint so that hexagonal cells are continuous is disclosed (for example, see Patent Document 3). In this fiber honeycomb structure, the opposing pleats of the left and right fiber pleat screens are sandwiched and bonded from both sides by the left and right V-shaped adhesive portions of the fiber joint. Specifically, an adhesive is applied to the inside of the left and right V-shaped adhesive portions of the fiber joint, and the pleats of the left and right pleat screens are put into the adhesive portions so as to be sandwiched therebetween, thereby bonding the honeycomb. A structure is obtained.

  In the fiber honeycomb structure configured as described above, the joint that connects the left and right fiber pleat screens is made of a woven fabric, and thus is well adapted to the bendable pleat screen. Also, since the bonding area of the left and right V-shaped joints of the fiber joint that holds the opposite pleats of the left and right pleat screens from both sides is quite large, the bond between the fiber joint and the left and right fiber pleat screens is strong. It is. As a result, the fiber joint is prevented from peeling from the left and right fiber pleat screens.

Japanese Patent Laying-Open No. 2011-84888 (Claim 1, paragraphs [0015] to [0019], FIGS. 1 to 3) Japanese Patent No. 2606944 (Claim 1, specification, third column, line 35 to same column, 39th line, specification, fourth column, third line to same column, sixth line, specification, fourth column, 33rd line to same) Column 36th line, FIG. 1 and FIG. 2) JP-A-7-266476 (Claim 1, paragraphs [0006] and [0009], FIGS. 1 and 2)

  However, in the pleated screen shown in the above-mentioned conventional patent document 1, when this pleated screen is viewed from the indoor side or the window side, the lifting cord is exposed to the high crease area of the screen material, and the appearance of the pleated screen is improved. There was a bug that damaged. In addition, the pleated screen disclosed in the above-mentioned conventional patent document 1 has a problem that it lacks versatility and design because it has a special screen material in which a plurality of high and low folds are alternately arranged. Furthermore, since the pleated curtain shown in the above-mentioned conventional patent document 2 uses only one piece of pleated fabric, there is a problem that the heat insulating effect cannot be exhibited. On the other hand, in the fiber honeycomb structure shown in Patent Document 3 above, the left and right fiber pleat screens are fixed by bonding via fiber joints, so the left and right fiber pleat screens have different materials. In this case, for example, when one of the left and right fiber pleated screens is thick and the other is thin, the screen may be curled (bent) due to a difference in physical properties such as the shrinkage rate of the left and right fiber pleated screens. This curl has a problem that it increases as the width of the pleated screen increases. Moreover, in the fiber honeycomb structure shown in the above-mentioned conventional Patent Document 3, the adhesion between the left and right fiber pleated screens and the fiber joint may be peeled off due to environmental changes such as temperature change and humidity change. There was also a problem that durability was relatively low. Furthermore, when one of the left and right pleated screens is formed of a fiber material and the other is formed of a film material, the adhesion between the two is peeled off due to an environmental change such as a change in temperature or a change in humidity, or is joined. There was also a problem that it was difficult.

  A first object of the present invention is to provide a pleated screen in which the connecting cord is not exposed to the room side and the window side and the appearance is not impaired. The second object of the present invention is to provide versatility by alternately inserting the connecting cords into the first through holes and the second through holes to form a general honeycomb-like screen body instead of a special shape. It is another object of the present invention to provide a pleated screen that can obtain a screen body excellent in design and can improve the heat insulation performance of the honeycomb-shaped screen body. A third object of the present invention is to form a honeycomb-shaped screen body using first and second pleated fabrics having different materials and the like, even if the physical properties of the first and second pleated fabrics are different. An object of the present invention is to provide a pleated screen capable of preventing the screen body from curling. The fourth object of the present invention is that the first pleated fabric and the second pleated fabric are not bonded, so that the situation where the bonding peels off due to environmental changes does not occur, and the deterioration of the durability of the screen body can be prevented. To provide a pleated screen.

  A first aspect of the present invention is a pleated screen having a honeycomb-shaped screen body 20 having an upper end attached to a head rail 11 and a bottom rail 12 attached to a lower end, as shown in FIGS. The main body 20 is folded in a zigzag shape, and the first pleat fabric 21 is formed in the other crease portion so as to protrude in the horizontal direction over the entire length of the crease, and is folded in a zigzag shape.

And having a first through hole 21b and the connecting cord 23 which is loosely inserted alternately into the second hole 22b in order to form a screen body 20.

  The second aspect of the present invention is an invention based on the first aspect. As shown in FIGS. 1 to 4, the upper end of the connecting cord 23 is introduced into the head rail 11 and passes through the cord guide 11a and the stopper. Are attached to the upper ends of the cord joints 11b, the bottom rails 12 are attached to the lower ends of the connecting cords 23, and the connecting cords 23 raise and lower the bottom rails 12 so that the honeycomb screen body 20 can be folded and unfolded. It is comprised so that it may serve as.

  The third aspect of the present invention is an invention based on the first aspect, and further, as shown in FIG. 5, the upper end is introduced into the head rail 11 and passes through the cord guide 11a and the stopper to the upper end of the cord joint 11b. Each of the first connecting pieces 51a is further provided with a lifting / lowering cord 54 that is attached to the lower end and has a bottom rail attached to the bottom rail so that the honeycomb-shaped screen main body 50 can be folded up and down. The first connecting piece 51a is separated from the first through hole 51b. A first through hole 51c is formed, a second through hole 52c is formed in the second connecting piece 52a separately from the second through hole 52b, and the lifting / lowering cords 54 are alternately arranged in the first through hole 51c and the second through hole 52c.

Further, when the plurality of first connection pieces 21a and the plurality of second connection pieces 22a are alternately stacked, the three first through holes 21b of each first connection piece 21a and the three of the second connection pieces 22a. The second through holes 22b are arranged so as to be connected in three rows. In this state, the connecting cords 23 are inserted into the first through holes 21b and the second through holes 22b alternately, that is, the three connecting cords 23 (FIG. 2) are inserted into the three rows of the first and second passages. The first pleated fabric 21 and the second pleated fabric 22 are connected by loosely inserting into the holes 21b and 22b, respectively, and the honeycomb-shaped screen body 20 is formed.

  On the other hand, the upper end of the connecting cord 23 is attached to the head rail 11, and the bottom rail 12 is attached to the lower end of the connecting cord 23 (FIGS. 1 and 2). The connecting cord 23 is configured to double as a lifting / lowering cord that unfolds the honeycomb screen main body 20 by raising / lowering the bottom rail 12. Specifically, a cord guide 11 a (FIG. 4) and a stopper (not shown) are provided in the head rail 11, and a cord joint 11 b is attached to the surface of the head rail 11 on the indoor side. The cord guide 11a is disposed in the head rail 11 so as to face the three rows of first and second through holes 21b and 22b formed in the first and second connecting pieces 21a and 22a, respectively. The stopper is configured to fix the connecting cord 23 in order to temporarily stop the bottom rail 12 at an arbitrary height. The upper end of the connecting cord 23 is introduced into the head rail 11 and attached to the upper end of the cord joint 11b through the cord guide 11a and the stopper. The upper end of the operation cord 24 is attached to the lower end of the cord joint 11b, and the lower end of the operation cord 24 is attached to the bottom rail 12 (FIGS. 1 to 3). By operating the operation cord 24, the bottom ends of the three connecting cords 23 are moved up and down, the bottom rail 12 is moved up and down, and the screen body 20 is configured to be foldable. In this embodiment, three first through holes are formed in each first connecting piece, three second through holes are formed in each second connecting piece, and three connecting cords are connected to the first connecting piece. The first through hole and the second through hole are alternately inserted freely, but the number of the first and second through holes may be two or four or more, and the number of connecting cords may be two or four or more. Good.

  The operation of the pleated screen 10 configured as described above will be described. The connecting cord 23 is idled alternately between the first through hole 21b formed in the first connecting piece 21a of the first pleated fabric 21 and the second through hole 22b formed in the second connecting piece 22a of the second pleated fabric 22. By inserting, the first pleated fabric 21 and the second pleated fabric 22 are connected to form the honeycomb-shaped screen body 20, so that the connecting cord 23 is not exposed to the indoor side and the window side, and the pleated screen 10 The appearance from the room side and the window side is not impaired. In addition, since the connecting cord 23 is inserted into the first through hole 21b and the second through hole 22b alternately, a general honeycomb-shaped screen body 20 can be formed instead of a special shape. Can be obtained, and the heat insulation performance of the honeycomb-shaped screen body 20 can be improved. That is, even if the air temperature inside the honeycomb-shaped screen body 20 changes, Can be suppressed.

  When the materials of the first pleated fabric 21 and the second pleated fabric 22 are changed, for example, the first pleated fabric 21 is made thick, the second pleated fabric 22 is made thin, and the pleated fabrics 21 and 22 are used to make a honeycomb. When the screen body 20 is formed, when the temperature and humidity change, the first pleated fabric 21 and the second pleated fabric 22 differ from each other due to the difference in physical properties between the first pleated fabric 21 and the second pleated fabric 22. It expands and contracts at an expansion rate or contraction rate. At this time, the different expansion and contraction amounts of the first and second pleated fabrics 21 and 22 are absorbed by the gap between the connecting cord 23 and the first through hole 21b and the gap between the connecting cord 23 and the second through hole 22b. As a result, no curling (bending) occurs in the honeycomb-shaped screen body 20, so that the appearance of the screen body 20 is not impaired.

  Further, the first connecting piece 21a of the first pleated fabric 21 and the second connecting piece 22a of the second pleated fabric 22 are simply inserted into the first through hole 21b and the second through hole 22b alternately. Is not adhered to each other, the situation where the bonded portion between the first connecting piece 21a and the second connecting piece 22a is peeled off due to environmental changes does not occur. As a result, a decrease in the durability of the screen body 20 can be prevented, and the number of steps for manufacturing the honeycomb-shaped screen body 20 can be reduced by omitting the bonding step between the first connection piece 21a and the second connection piece 22a. Further, since the connecting cord 23 also serves as a lifting / lowering cord that unfolds the honeycomb-shaped screen main body 20 by raising / lowering the bottom rail 12, the number of parts and the number of assembling steps can be reduced. Further, by forming the first pleated fabric 21 on the indoor side with a fiber material and forming the second pleated fabric 22 on the window side with a heat-shielding type film material, the heat insulation performance is improved without impairing the appearance of the indoor side. be able to.

  Furthermore, when a plurality of different types of first pleat fabric 21 and second pleat fabric 22 are prepared, the combination of these pleat fabrics 21 and 22 is the square of the number of types. The amount of inventory can be reduced by separately managing the second pleated fabric 22. For example, if 10 types of the first pleated fabric 21 and the second pleated fabric 22 are prepared, 100 combinations (10 × 10) of these pleated fabrics 21 and 22 are possible, and 100 combinations are possible. Become. In this case, when the first pleated fabric 21 and the second pleated fabric 22 are managed as the assembled screen body 20, the number of managed parts becomes 100, whereas the first pleated fabric 21 and the second pleated fabric 22 If these are managed separately, only 20 types of parts can be managed. The screen body 20 is assembled using the first pleated fabric 21 and the second pleated fabric 22 when delivered to a store or the like.

  In the pleated screen 70 configured as described above, the connecting cord 83 is inserted into the first through hole 81b of the first connecting piece 81a and the second through hole 82b of the second connecting piece 82a alternately, and the lifting / lowering cord 84 is passed through. Since it is loosely inserted into the hole 82c, the first and second pleated fabrics 81, 82 are connected by the connecting cord 83, and the screen body 80 is unfolded by the lifting / lowering cord 84 so that it can be folded. Further, since the connecting cord 83 is not exposed to the indoor side and the window side, and the elevating cord 84 is not exposed to the indoor side, the appearance of the pleated screen 70 from the indoor side is not impaired. Further, since the lifting / lowering cord 84 is passed only through the second pleated fabric 82, the number of assembling steps of the screen body 80 can be reduced as compared with the case where the lifting / lowering cord 84 is passed through both the first and second pulley fabrics 81 and 82. Since the operation other than the above is substantially the same as the operation of the first embodiment, repeated description will be omitted.

<Fourth embodiment>
FIG. 7 shows a fourth embodiment of the present invention. 7, the same reference numerals as those in FIG. 4 denote the same components. In this embodiment, the connecting cord 113 is an elevating cord 114 that has an upper end introduced into the head rail 11 and a bottom rail attached to the lower end, and the bottom rail is moved up and down so that the honeycomb-shaped screen body 110 can be folded. It is provided separately. And this raising / lowering cord 114 is loosely inserted alternately by the 1st through-hole 111b and the 2nd through-hole 112b with the connection cord 113. FIG. Specifically, the first through-hole 111b formed in the first connection piece 111a of the first pleat fabric 111 is formed as a long hole extending in the longitudinal direction of the first connection piece 111a, and the second pleat fabric 112 second The 2nd through-hole 112b formed in the connection piece 112a is formed in the long hole extended in the longitudinal direction of the 2nd connection piece 112a. The elevating cord 114 is loosely inserted alternately into the first through-hole 111b and the second through-hole 112b together with the connecting cord 113. The upper end of the connecting cord 113 is attached to the lower surface of the head rail 11, and the upper end of the elevating cord 114 is introduced into the head rail 11 and attached to the upper end of the cord joint 11b through the cord guide 11a and the stopper. Furthermore, in this embodiment, the number of connecting cords 113 and lifting / lowering cords 114 is two each. However, the connecting cord 113 and the lifting / lowering cord 114 are not limited to these numbers. The configuration other than the above is the same as that of the first embodiment.

  In the pleated screen 100 configured as described above, the lifting / lowering cord 114 and the connecting cord 113 are inserted into the first through hole 111b and the second through hole 112b alternately, so that the first and second connecting pieces 111a and 112a are inserted into the first and second connecting pieces 111a and 112a. The number of holes 111b and 112b formed can be reduced. As a result, the processing man-hours for the first and second pleated fabrics 111, 112 can be reduced, and the man-hours for passing the lifting / lowering cord 114 and the connecting cord 113 through the holes 111b, 112b can be reduced. Since the operation other than the above is substantially the same as the operation of the first embodiment, repeated description will be omitted.
