Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a retaining tape used for retaining various materials to be attached, for example, a retaining tape used for retaining a net material that can be extended and wound up from a frame material of a roll screen door.

2. Description of the Related Art Conventionally, there has been known a windable insect screen door in which an insect net (attached material) can be freely extended and wound around a winding shaft (see Patent Document 1).
This insect screen door includes a winding box containing the winding shaft, a pair of screen guides (frame members) extending from both ends of the winding box, and engaging screens attached to left and right side edges of the insect screen. The small projection for engagement is movable along the screen guide and engaged with the inner edge of the slit provided in the screen guide in a manner to prevent it from coming off.

JP 2018-80535 A

By the way, in the insect screen door described in Patent Literature 1, the engaging small protrusions are configured by coil elements formed in a coil shape. Since the small engaging projection has a rounded shape, there is a manufacturing limit to reduce the dimension (thickness dimension) of the small engaging projection along the out-of-plane direction of the insect net. For this reason, it is difficult to reduce the size of the screen guide that accommodates the small engaging projections therein.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a retaining tape capable of reducing the thickness of a retaining portion and reducing the size of a frame member.

The retaining tape of the present invention is a retaining tape for retaining a material attached to a frame material, and comprises a first tape portion and a second tape portion that can be sandwiched between the edges of the material to be attached, A first linear overlapping portion provided along the longitudinal direction of the first tape portion, a second linear overlapping portion provided along the longitudinal direction of the second tape portion, and the first linear overlapping portion and a folded portion provided between the second linearly overlapped portion, wherein the first linearly overlapped portion and the second linearly overlapped portion overlap each other in the folded state of the folded portion and are pulled out. It is characterized by having a wire that constitutes the stop portion.
According to the retainer tape of the present invention, since the wire rods of the first and second linearly overlapped portions are overlapped by folding back the folded portion, there is no need to coil the wire rods on both sides of the screen. . For this reason, for example, compared to the case where the retaining portion is configured by a coil-shaped continuous coil element fixed to the tape portion, the thickness dimension (longitudinal direction and width direction of the retaining tape (dimension in the thickness direction orthogonal to ) can be reduced, and the expected dimension of the frame member with which such a retainer is engaged can be reduced.
In addition, since the folded portion is provided between the first and second linear overlapping portions, the first and second linear overlapping portions can be easily aligned by folding back the folded portion.
The retainer tape configured in this way can be used as a retainer for various attached members.

In the retaining tape of the present invention, the wire rod may be formed of a monofilament thread.
According to such a configuration, a wire having both rigidity and formability can be formed by adopting the monofilament thread. For example, a metal wire has rigidity but low moldability, and if the diameter is increased, it becomes too hard and bendability is reduced. Further, for example, multifilament yarns have moldability but low rigidity. On the other hand, by forming the wire from the monofilament yarn as in the present invention, it is easy to mold, and even if the retaining portion is formed, it is not easily crushed, so the possibility that the retaining tape will come off can be reduced. Even if the dimension is increased, it does not become as hard as the metal wire and can maintain moderate bendability.

In the retaining tape of the present invention, the diameter of the wire rod is uniform, and the retaining portion has a flat imaginary outer surface along the longitudinal direction of the retaining tape and the width direction perpendicular to the longitudinal direction of the retaining tape. You may be comprised by the wire.
According to such a configuration, when the material to be attached is wound, the wire rods forming the flat imaginary outer surface described above are overlapped with each other in the wound state. It is possible to suppress the occurrence of winding misalignment in the direction perpendicular to the longitudinal direction of the retaining tape, as compared with the case where it is employed as the retaining portion.

In the retaining tape of the present invention, the first tape portion and the second tape portion are composed of a knitted structure in which knitting yarn is woven, and the first linear overlapping portion and the second linear overlapping portion are: It may be constituted by a knitted structure in which a knitting yarn having a diameter larger than that of the knitting yarn is knitted.
According to such a configuration, the thickness dimension of the knitting structure of the first linear overlapping portion and the second linear overlapping portion can be made larger than that of the knitting structure of the first tape portion and the second tape portion. The stop portion can be made large.

In the retaining tape of the present invention, the first tape portion and the second tape portion are composed of a knitted structure in which a plurality of types of knitting yarns are knitted, and the first linear overlapping portion and the second linear overlapping portion are formed. The portion may be composed of a knitted structure in which more types of knitting yarns than those of the knitting yarns forming the first tape portion and the second tape portion are knitted.
According to such a configuration, the thickness dimension of the knitting structure of the first linear overlapping portion and the second linear overlapping portion can be made larger than that of the knitting structure of the first tape portion and the second tape portion. The stop portion can be made large.

In the retaining tape of the present invention, the wire includes a plurality of overlapping line portions extending in a width direction orthogonal to the longitudinal direction of the retaining tape, and a plurality of continuous line portions connecting the plurality of overlapping line portions. and the overlapping line portion of the first linear overlapping portion and the overlapping line portion of the second linear overlapping portion may face each other in the width direction so as to be arranged overlapping each other.
According to such a configuration, the retaining portion can be configured by folding back the folded portion and arranging overlapping line portions facing each other in the width direction. In addition, compared to, for example, the first and second linear overlapping portions having a plurality of wire rods arranged side by side at intervals along the longitudinal direction of the retaining tape, the wire can be easily installed and the longitudinal direction of the retaining tape can be reduced. It is possible to improve the space retention property for keeping the space between the overlapping line portions in the direction.
Moreover, since a continuous wire rod is used, it is easier to manufacture than when a plurality of wire rods are arranged, and it is possible to achieve a structure that is less likely to come off from the first linear overlapped portion and the second linear overlapped portion.

In the retaining tape of the present invention, the plurality of continuous line portions include one end portion connecting one end of each of the plurality of overlapping line portions adjacent to each other in the longitudinal direction of the retaining tape. There is a continuous line portion and a continuous line portion that connects the other end portions of the overlapping line portions that are adjacent to each other in the longitudinal direction of the retaining tape, and the one continuous line is provided. The part and the other continuous line part may be alternately arranged along the longitudinal direction of the retaining tape.
According to such a configuration, it is possible to form a meandering wire rod that does not have a linear portion that is long and continuous along the longitudinal direction of the retainer tape. , the retaining tape can be easily bent.

In the retaining tape of the present invention, the one continuous line portion of the first linear overlapping portion and the one continuous line portion of the second linear overlapping portion are arranged on the folded portion side. In addition, they may be arranged at different positions in the longitudinal direction of the retaining tape.
According to such a configuration, one continuous line portion of the first linear overlapping portion and one continuous line portion of the second linear overlapping portion are arranged at different positions in the longitudinal direction of the retaining tape. , it is possible to suppress interference between these continuous line portions. For this reason, compared to the case where one continuous line portion of the first linear overlapped portion and one continuous line portion of the second linear overlapped portion face each other in the width direction, the width dimension of the folded portion is reduced. It can be made smaller, and the size can be set so that it can be widely adapted to the thickness of the material to which the retaining tape is fixed.

In the retaining tape of the present invention, the plurality of wires are arranged side by side at intervals in the longitudinal direction of the retaining tape, and the plurality of wires extend in the width direction perpendicular to the longitudinal direction of the retaining tape. each having a pair of overlapping line portions and a continuous line portion connecting the pair of overlapping line portions, wherein the overlapping line portion in the first linear overlapping portion and the overlapping line in the second linear overlapping portion The portions may face each other in the width direction so that they can be arranged overlapping each other.
According to such a configuration, the retaining portion can be configured by folding back the folded portion and arranging overlapping line portions facing each other in the width direction. In addition, compared to the first and second linear overlapping portions, which have wires that are continuous along the longitudinal direction of the retaining tape, for example, the retaining tape can be easily bent because the plurality of wires are not continuous. Therefore, for example, even if the diameter of the wire is increased to form a large retaining portion, the retaining tape can maintain its bendability.

In the retaining tape of the present invention, the continuous line portion may connect end portions of the pair of overlapping line portions on the side opposite to the folded portion.
With such a configuration, since there is no continuous line portion on the folded portion side, the plurality of wires can be fixed at positions that do not protrude toward the folded portion side. width can be reduced. As a result, it is possible to reduce the size of the entire retaining tape.

In the retaining tape of the present invention, the continuous line portion of the first linear overlapping portion and the continuous line portion of the second linear overlapping portion are arranged at different positions in the longitudinal direction of the retaining tape. may
According to this configuration, the continuous line portion of the first linear overlapping portion and the continuous line portion of the second linear overlapping portion are arranged at different positions in the longitudinal direction of the retaining tape. Interference between parts can be suppressed. For this reason, the width dimension of the folded portion can be made smaller than, for example, when the continuous line portion of the first linear overlap portion and the continuous line portion of the second linear overlap portion are opposed to each other in the width direction, The dimensions can be set to accommodate a wide range of thicknesses of the material to which the retaining tape is fixed.

In the retainer tape of the present invention, the width dimension in the width direction orthogonal to the longitudinal direction of the folded portion is smaller than the width dimension in the width direction of the first linear overlapping portion and the second linear overlapping portion. good too.
According to such a configuration, the first and second linear overlapping portions are arranged to overlap each other by folding back the folded portion, so that they can be easily aligned. In addition, even if the first and second linearly overlapped portions are arranged in a folded state, the length of protrusion of the folded portion from the first and second linearly overlapped portions can be reduced. The width dimension in the state can be reduced, and the outside dimension of the frame material can be reduced. Furthermore, even if the nominal size of the frame member is reduced in this way, it is possible to provide a clearance between the folded portion and the frame member, thereby suppressing interference between the retaining tape and the frame member. can.

The continuous line portions 62 and the continuous line portions 63 are alternately arranged along the X-axis direction, so that the wire rod 60 as a whole extends in the X-axis direction in a meandering shape. A continuous line portion 62 and two overlapping line portions 61 adjacent to each other constitute a U-shaped portion, and a continuous line portion 63 and two overlapping line portions 61 adjacent to each other constitute an inverted U-shaped portion. A continuous portion between the overlapping line portion 61 and the continuous line portions 62 and 63 has a curved shape.
The second linear overlapping portion 40B is configured substantially in the same manner as the first linear overlapping portion 40A. The other end portions of the multiple overlapping line portions 61 on the second tape portion 30B side are connected to each other by a continuous line portion 63, and the continuous line portion 62 and the continuous line portion 63 extend along the X-axis direction. By being alternately arranged, the wire 60 as a whole forms a meandering shape and extends in the X-axis direction.
The overlapping line portion 61 in the first linear overlapping portion 40A and the overlapping line portion 61 in the second linear overlapping portion 40B are arranged to face each other in the Y-axis direction so that they can overlap each other in the folded state of the folded portion 50. ing.
The continuous line portion 62 in the first linear overlapping portion 40A and the continuous line portion 62 in the second linear overlapping portion 40B are located at different positions in the X-axis direction. is arranged at a position between two continuous line portions 62 in the second linear overlapping portion 40B. Therefore, the continuous line portion 62 in the first linear overlapping portion 40A and the continuous line portion 63 in the second linear overlapping portion 40B are arranged to face each other in the Y-axis direction, and The continuous line portion 63 and the continuous line portion 62 in the second linear overlapping portion 40B are arranged to face each other in the Y-axis direction.

The first linear overlapped portion 40A and the second linear overlapped portion 40B are arranged such that the wires 60 overlap each other in the folded state of the folded portion 50 . In this embodiment, the retaining portion 40 is formed by the first linear overlapping portion 40A and the second linear overlapping portion 40B which are arranged to overlap each other by weaving the folded portion 50, and the net 20 sandwiched between them. is configured.
A meandering wire 60 is exposed on both sides of the retainer 40 . Each wire rod 60 extends along a virtual plane defined in the X-axis direction and the Y-axis direction. Therefore, each wire rod 60 forms a flat imaginary outer surface 65 along the X-axis direction and the Y-axis direction.

The folded portion 50 is a single warp connected to each chain stitch yarn 43 positioned on the folded portion 50 side among the plurality of rows of the chain stitch yarns 43 in the first linear overlapping portion 40A and the second linear overlapping portion 40B.

Here, the first tape portion 30A and the second tape portion 30B are configured by knitting a plurality of three types of knitting yarns, and the first linear overlapped portion 40A and the second linear overlapped portion 40B are constituted by a plurality of three types of knitting yarns. While the folded portion 50 is of a single type and is composed of a single warp-inserted yarn 51, the first tape portion 30A and the second tape portion 30B are formed by weaving and attaching the wire rod 60. In addition, the thickness dimension is smaller than that of the first linear overlapping portion 40A and the second linear overlapping portion 40B, making it easier to fold back.

The first tape portion 30A and the second tape portion 30B, the first linear overlapping portion 40A and the second linear overlapping portion 40B, and the folded portion 50 are woven as described above. The knitting yarn used, the number of types, the knitting method, etc. may be appropriately changed according to the required product properties. For example, the first tape portion 30A and the second tape portion 30B are configured by knitting three types of knitting yarns without using reverse warp-inserted yarns, but four types of knitting yarns are knitted using reverse warp-inserted yarns. may be composed of In addition, the first linear overlapping portion 40A and the second linear overlapping portion 40B are configured by knitting three types of knitting yarns without using the tricot knitting yarn 33, but using the tricot knitting yarn 33, four types of knitting yarns are used. It may be configured by knitting knitting yarn.

It can be made larger than the thickness dimension of the knitted structure. Further, by making the types of knitting yarns constituting the first linear overlapping portion 40A and the second linear overlapping portion 40B larger than the kinds of knitting yarns constituting the first tape portion 30A and the second tape portion 30B, , the thickness dimension of the knitted structure of the first linear overlapped portion 40A and the second linear overlapped portion 40B can be made larger than the thickness dimension of the knitted structure of the first tape portion 30A and the second tape portion 30B. By doing so, it is possible to further increase the engagement margin between the guide rail 17 and the retaining portion 40 when the net 20 is about to be pulled out, thereby improving the retaining property.

Dimensional relationships of the retaining tape 10 are as follows.
The thickness dimension in the Z-axis direction of the first linear overlapping portion 40A is larger than the thickness dimension in the Z-axis direction of the first tape portion 30A, and the second linear overlapping portion 40B and the second tape portion Each thickness dimension in the Z-axis direction of 30B is equal to each thickness dimension of the first linear overlapping portion 40A and the first tape portion 30A. A thickness dimension T1 in the Z-axis direction of the retaining portion 40 is a thickness dimension in the Z-axis direction including the first linear overlapping portion 40A, the second linear overlapping portion 40B, and the net 20 positioned therebetween. . The thickness dimension T1 of the retaining portion 40 is set to be larger than the thickness dimension T2 of the tape portion 30 including the first tape portion 30A, the second tape portion 30B and the net 20 in the Z-axis direction.
The width dimension W1 of the first linear overlapping portion 40A in the Y-axis direction is the same as the width dimension W2 of the first tape portion 30A in the Y-axis direction, and the second linear overlapping portion 40B and the second tape portion 30B are equal to the widths W1, W2 of the first linear overlapping portion 40A and the first tape portion 30A in the Y-axis direction. The width dimension W1 of the retaining portion 40 in the Y-axis direction is the same dimension as the width dimension W2 of the tape portion 30 in the Y-axis direction.
The width dimension W3 of the folded portion 50 in the Y-axis direction is smaller than the width dimension W1 of the first linear overlapping portion 40A and the second linear overlapping portion 40B.

The diameter dimension (wire diameter) of each wire rod 60 is 0.3 mm, and the pitch between the U-shaped portions and the pitch between the inverted U-shaped portions formed in the wire rod 60 is 0.9 mm (three times the diameter dimension of the wire rod 60). degree). The thickness dimension of the first tape portion 30A and the second tape portion 30B is 0.3 mm, and the thickness of the first linear overlapping portion 40A and the second linear overlapping portion 40B having the wire 60 is 0.6 mm. The width dimension W1 of the first linear overlapping portion 40A and the second linear overlapping portion 40B, that is, the width dimension W1 of the retaining portion 40 is 2 mm, and the width dimension W2 of the first tape portion 30A and the second tape portion 30B. That is, the width dimension W2 of the tape portion 30 is 2 mm, and therefore the width dimension W of the retaining tape 10 in the folded state is 4 mm. The thickness T1 of the retaining portion 40 is 1.35 mm (the sum of the thicknesses of the first linear overlapping portion 40A and the second linear overlapping portion 40B and the thickness of the net 20). The thickness T2 of the net 20 is 0.75 mm (the sum of the thicknesses of the first tape portion 30A and the second tape portion 30B and the thickness of the net 20). The dimensional difference between the thickness dimensions T1 and T2 is 0.6 mm. The width dimension W3 of the folded portion 50 is 1 mm (preferably 1 mm or less).
The diameter of the wire rod 60 may be 0.3 mm or less as long as it is possible for manufacturing, and the pitch between the U-shaped portions of the wire rod 60 and the pitch between the inverted U-shaped portions is 0.9 mm or less (wire rod 60), the thickness T1 of the retaining portion 40 may be 1.35 mm or less, and the thickness T2 of the tape portion 30 may be 0.35 mm or less. It may have a dimension of 75 mm or less.

The opening width OW of the guide groove 17A is smaller than 0.75 mm, so that the guide rail 17 is configured so that the tape portion 30 is difficult to be pulled out from the opening 17B. It should be noted that the opening width dimension OW may be a dimension smaller than the thickness dimension T1 (a dimension smaller than 1.35 mm in this embodiment) so that the retaining portion 40 can be retained. Therefore, the opening width dimension OW may be equal to or larger than the thickness dimension T2 of the tape portion 30 as long as the tape portion 30 is pulled out from the opening 17B and exposed without any problem in appearance.

The operation of the roll screen door 1 using the retaining tape 10 according to this embodiment will be described below.
In the closed state shown in FIG. 6, even if the net 20 is pulled out from the guide groove 17A in the Y-axis direction under the influence of wind pressure or the like, the retaining portion 40 abuts the opening forming piece portion 173 to retain the net 20. do. In addition, even if the retaining portion 40 contacts the opening forming piece portion 173 when the net 20 is wound or unwound, the wire rod 60 that actually contacts the opening forming piece portion 173 is made of resin (polyethylene terephthalate (PET) in this embodiment). , the sliding resistance of the retaining portion 40 against the guide rail 17 can be kept small, and the net 20 can be smoothly slid. Furthermore, in this embodiment, the guide rails 17 are also made of resin, so that the above-described sliding resistance can be further reduced.
Further, when the movable frame 24 is operated to the left to open the closed state, the winding shaft 13A rotates in the winding direction around the axis, and the net 20 and the retaining tape 10 are moved by the winding shaft 13A. It is wound up and stored in the storage case 13 . In the winding state in which the net 20 is wound around the winding shaft 13A in a spiral cross section, the imaginary outer surface 65 of the retainer tape 10 is adjacent in the orthogonal direction B perpendicular to the axial direction A, as shown in FIG. It overlaps with the imaginary outer surface 65 , whereby the retaining portion 40 is overlapped in the orthogonal direction B. As shown in FIG. Here, since the imaginary outer surface 65 is formed flat by the wire rod 60, it is possible to suppress the occurrence of positional displacement in the axial direction A even when the retaining portions 40 are overlapped with each other. Therefore, it is possible to eliminate the possibility that the net 20 is wrinkled due to the positional deviation.

[Effect of this embodiment]
(1) In the present embodiment, the retaining tape 10 includes a first tape portion 30A and a first linear overlapping portion 40A shown on the left side in FIG. 2, and a second tape portion 30B and a second linear overlapping portion shown on the right side in FIG. 40B, and a folded portion 50 provided between the first linear overlapping portion 40A and the second linear overlapping portion 40B. As shown in FIG. The wire rods 60 of the linear overlapped portion 40A and the second linear overlapped portion 40B are arranged so as to overlap each other in the Z-axis direction, thereby forming the retainer portion 40. As shown in FIG.
According to this retaining tape 10, the thickness dimension T1 can be made smaller within a range where it functions as a retaining function, compared to the case where a coil element is employed for the retaining portion 40, for example. Therefore, the estimated dimension of the guide rail 17 in which the retaining tape 10 is accommodated in the guide groove 17A can be reduced in accordance with the reduction in the thickness dimension T1, and the size of the guide rail 17 can be reduced.
In addition, by providing the folded portion 50 between the first linearly overlapped portion 40A and the second linearly overlapped portion 40B, the first linearly overlapped portion 40A and the second linearly overlapped portion 40B are equal to the width of the folded portion 50. Mutual misalignment beyond the dimension W3 can be eliminated, so that the first linear overlapped portion 40A and the second linear overlapped portion 40B can be easily aligned when forming the retaining portion 40. can.

(2) The wire 60 is made of monofilament thread. Therefore, by adopting the monofilament thread, the wire rod 60 having both rigidity and formability can be formed. For example, a metal wire has rigidity but low moldability, and if the diameter is increased, it becomes too hard and bendability is reduced. Also, for example, multifilament yarns have moldability but low rigidity. There is On the other hand, by forming the wire rod 60 with a monofilament thread, it is easy to mold, and even if the retaining portion 40 is formed, it is less likely to be crushed. , even if the diameter is increased, it does not become as hard as the metal wire and can maintain moderate bendability.
(3) The diameter dimension of the wire 60 is uniform along its wire direction, and the wire 60 forms a flat imaginary outer surface 65 along the X-axis direction and the Y-axis direction of the retaining portion 40 . Therefore, in the winding state (winding state) of the net 20 in the roll screen door 1, the flat imaginary outer surfaces 65 are superimposed on each other, so that the occurrence of winding misalignment in the Y-axis direction can be suppressed.

(4) The first tape portion 30A and the second tape portion 30B are composed of a knitting structure in which the knitting yarn is knitted, and the first linear overlapping portion 40A and the second linear overlapping portion 40B are formed from the knitting yarn. It may be constituted by a knitted structure in which knitting yarn having a large diameter is knitted. In this case, the thickness dimension of the knitted structure of the first linear overlapped portion 40A and the second linear overlapped portion 40B can be increased with respect to the knitted structure of the first tape portion 30A and the second tape portion 30B. The portion 40 can be made large.
(5) The first tape portion 30A and the second tape portion 30B are configured by a knitting structure in which a plurality of types of knitting yarns are knitted, and the first linear overlapped portion 40A and the second linear overlapped portion 40B are composed of the first The tape portion 30A and the second tape portion 30B may be configured by a knitting structure in which more types of knitting yarns are knitted than the types of knitting yarns forming the tape portion 30A and the second tape portion 30B. In this case, the thickness dimension of the knitted structure of the first linear overlapped portion 40A and the second linear overlapped portion 40B can be increased with respect to the knitted structure of the first tape portion 30A and the second tape portion 30B. The portion 40 can be configured large.

(6) The overlapped line portion 61 of the first linear overlapped portion 40A and the overlapped portion 61 of the second linear overlapped portion 40B face each other in the Y-axis direction so as to overlap each other. Therefore, when the folded portion 50 is folded back, the overlapping line portions 61 facing each other in the Y-axis direction are overlapped with each other, so that the retainer portion 40 that is less likely to be crushed in the Z-axis direction can be configured. In addition, since the wire rod 60 is long and continuous in the X-axis direction, it is possible to easily install the wire rod 60 and to improve the space maintenance performance of maintaining the space between the overlapped wire portions 61 in the X-axis direction.
In addition, since the continuous wire rod 60 is used, it is easier to manufacture than the case where a plurality of wire rods 70 are arranged as described later, and the knitting of the first linear overlapped portion 40A and the second linear overlapped portion 40B is possible. It can be configured to be difficult to come off from the tissue.
(7) The continuous line portion 62 connects the ends (one ends) of the overlapping line portions 61 adjacent to each other in the X-axis direction on the side of the folded portion 50, and the continuous line portions 63 are connected to each other in the X-axis direction. The other end portions of the adjacent overlapped line portions 61 on the side opposite to the one end portion are connected to each other, and these continuous line portions 62 and 63 are alternately arranged along the X-axis direction. For this reason, it is possible to form a meandering wire rod 60 that is linearly long and continuous along the X-axis direction and has no straight portion. 10 can be configured to be easily bent.
(8) The continuous line portion 62 of the first linear overlapped portion 40A and the continuous line portion 62 of the second linear overlapped portion 40B are arranged on the folded portion 50 side and are located at different positions in the X-axis direction. are placed. Therefore, even if the width dimension W3 of the folded portion 50 is set small, it is possible to prevent the continuous line portions 62 from interfering with each other. Further, in the folded state of the folded portion 50, the continuous line portion 62 of the first linear overlapping portion 40A is the end of the folded portion 50 side of the overlapping line portion 61 of the second linear overlapping portion 40B when viewed from the Z-axis direction ( The continuous line portion 63 of the first linear overlapping portion 40A is arranged between the other ends of the overlapping line portions 61 of the second linear overlapping portion 40B, and the second linear overlapping portion The continuous line portion 62 of the portion 40B is arranged between the end (one end) of the folded line portion 61 of the first linear overlapping portion 40A on the side of the folded portion 50, and the continuous line portion of the second linear overlapping portion 40B. 63 is arranged between the other ends of the overlapping line portions 61 of the first linear overlapping portion 40A to form a ladder shape. This makes it possible to obtain stable bending characteristics.
(9) The width dimension W3 of the folded portion 50 is smaller than the width dimension W1 of the first linear overlapping portion 40A and the second linear overlapping portion 40B. Therefore, by folding back the folded portion 50, the first linear overlapping portion 40A and the second linear overlapping portion 40B overlap each other in the Z-axis direction without being deviated in the Y-axis direction, thereby facilitating the alignment. obtain. By decreasing the width dimension W3 of the folded portion 50, the dimension of the folded portion 50 protruding outward in the Y-axis direction from the first linear overlapping portion 40A and the second linear overlapping portion 40B in the folded state can be reduced. can. As a result, the width dimension W of the retainer tape 10 itself can be reduced, and the nominal dimension of the guide rail 17 can be reduced accordingly. Furthermore, even when the nominal size of the guide rail 17 is reduced in this way, it is possible to provide a clearance between the folded portion 50 and the guide rail 17, so that the retaining tape 10 and the guide rail 17 are separated. Interference can be suppressed.

(10) As described above, since the width dimension W of the retaining tape 10 can be reduced, even if the entire retaining tape 10 is accommodated in the guide groove 17A, it is easy to suppress an increase in the nominal dimension of the guide rail 17. , the roll screen door 1 in which the guide rail 17 is inconspicuous can be configured, and the appearance can be improved.
(11) Since the thickness T1 of the retaining portion 40 can be reduced as described above, the winding diameter when the net 20 and the retaining tape 10 are wound around the winding shaft 13A can be reduced.
(12) Since the wire rod 60 has a meandering shape and the width dimension W1 is increased to some extent, it is possible to more effectively suppress winding misalignment in the Y-axis direction.
(13) Since the first tape portion 30A and the second tape portion 30B are sewn and joined to the net 20, a heat welding process is not required, and the cost can be reduced by simplifying the manufacturing process. Therefore, the guide rail 17 and the retaining tape 10 can be prevented from interfering with each other, and the retaining tape 10 can be smoothly slid along the guide rail 17.例文帳に追加
(14) For example, the retaining portion 40 may be configured by placing a rubber sheet on the tape portion 30 fixed to the side edge portion 20A of the net 20. In this case, the rubber sheet and the guide rail 17 This increases the sliding resistance of the net 20, which may make it difficult to smoothly open and close the net 20. Further, when the rubber sheet is heat-sealed, heat shrinkage may occur as described above, and it may easily interfere with the guide rail 17. Sewing shrinkage (puckering) may sometimes occur.
On the other hand, in the present embodiment, the retaining portion 40 is configured by having the wire rod 60 formed of the resin monofilament thread as described above without adopting the rubber sheet. The sliding resistance of the guide rails 17 can be kept small, and the net 20 can be smoothly opened and closed. Moreover, since the first tape portion 30A and the second tape portion 30B are only sewn and joined to the net 20, there is no risk of heat shrinkage due to heat welding, and the risk of puckering can be reduced because there is no rubber sheet.

[Modification]
In the above-described embodiment, the wires 60 extending in a meandering shape in the X-axis direction were described, but the present invention is not limited to this. may be provided. The plurality of wire rods 70 each have a pair of overlapping wire portions 61 extending in the Y-axis direction and a continuous wire portion 62 connecting the pair of overlapping wire portions 61, and are formed in a U shape. The portion 62 connects the ends (one ends) of the pair of overlapping line portions 61 on the folded portion 50 side. The overlapping line portion 61 in the first linear overlapping portion 40A and the overlapping line portion 61 in the second linear overlapping portion 40B face each other in the Y-axis direction so as to be arranged so as to overlap each other. The continuous line portion 62 in the first linear overlapping portion 40A and the continuous line portion 62 in the second linear overlapping portion 40B are arranged at different positions in the X-axis direction.
According to such a configuration, the retaining portion 40 can be configured by folding the folded portion 50 and overlapping the overlapped portions 61 facing each other in the Y-axis direction. Since the plurality of wires 70 are not continuous and are arranged at intervals in the X-axis direction, compared to the case of having a long continuous wire in the X-axis direction, for example, the diameter of the wire 70 is increased to prevent it from coming off. Even if the portion is formed large, the bendability of the retaining tape 10 can be maintained.
Further, the continuous line portion 62 of the first linear overlapping portion 40A and the continuous line portion 62 of the second linear overlapping portion 40B are arranged at different positions in the X-axis direction, so that the width dimension W3 of the folded portion 50 is reduced to Even if it is made smaller, it is possible to prevent the continuous line portions 62 from interfering with each other.

Further, as shown in FIG. 5, a wire rod 70 having a continuous line portion 63 that connects the ends of the overlapping line portions 61 on the opposite side, instead of the continuous line portion 62 on the side of the folded portion 50, is arranged along the X axis. A plurality of them may be arranged side by side at intervals in the direction.
In this case, since there is no continuous line portion 62 on the folded portion 50 side, the plurality of wire rods 70 can be sewn to a position that does not protrude toward the folded portion 50 side. The width dimension W1 of the shaped overlapping portion 40B can be reduced. As a result, it is possible to reduce the size of the entire retaining tape 10 .

In the above-described embodiment, the first tape portion 30A and the second tape portion 30B are sewn and joined to the net 20. However, the present invention is not limited to this. In some cases, it may be heat-sealed.
In the above embodiment, a row of first linear overlapping portions 40A is provided on the left side of the folded portion 50, and a row of second linear overlapping portions 40B is provided on the right side of the folded portion 50. However, it is not limited to this. For example, two or more rows of first linear overlapping portions 40A are installed on the left side of the folded portion 50, and two or more rows of second linear overlapping portions 40B are installed on the right side of the folded portion 50. , the retaining portion 40 having a large width dimension W1 may be constructed.
In the above-described embodiment, the wire rod 60 has a plurality of U-shaped portions and inverted U-shaped portions. A plurality of S-shaped portions and inverted S-shaped portions may be formed by curving the continuous line portions 62 and 63 in an arc shape.
In the above-described embodiment, the wires 60 and 70 are formed of PET monofilament yarns, but are not limited to this, and may be formed of weft monofilament yarns such as PP, polyamide, PVC, PBT, and polyethylene. Also, the wires 60 and 70 may be formed of materials other than monofilament yarns, such as metal wires and multifilament yarns, and may employ metal fibers, carbon fibers, synthetic fibers, and the like.
Although the horizontal slide type roll screen door 1 in which the movable frame 24 can be operated in the horizontal direction has been described as one that uses the retaining tape 10, a vertical slide type roll in which the movable frame 24 can be operated in the vertical direction has also been described. A screen door may be used, and instead of the net 20, a roll screen device capable of winding and unwinding a screen for blocking sunlight may be used.
