On the other hand, instead of forming a joint piece by welding the bent fabric or the overlapped fabric in a broken line shape, the line shape is formed in the left-right direction of the screen and is perpendicular to the left-right direction of the screen. There is also known a technique of continuously welding a dough in one direction using a predetermined unit welding pattern (see, for example, Patent Document 1).

The fabric having such a joint piece can be used for a shielding device such as a roman shade, a vertical blind, a horizontal blind, a curtain rail, or an accordion curtain, in addition to the pleated screen.

By the way, in order to use a fabric having a joint piece as a shielding material for a shielding device, an insertion hole for inserting, for example, an elevating cord as described above is provided in the joint piece so as to meet the specifications of the shielding device. There is a need.

(Pleated screen)
FIG. 1 is a side view showing a schematic configuration of a pleated screen configured as a shielding device according to an embodiment of the present invention. In the pleated screen shown in FIG. 1, a shielding material (screen 7 in this example) that can be bent in a zigzag shape in the vertical direction is suspended and supported from the head box 1, and the screen 7 is provided on the head box 1 (operation device). It is moved up and down by an operation code 9 (for example, a ball chain) via an operation code 9 (not shown) to appropriately adjust the amount of lighting.

The screen 7 is provided with a joint piece 7b formed by welding based on the welding pattern according to the present invention, at each crease on one side of the fabric in which the crease 7a is provided in a zigzag shape. The joining piece 7b can be formed by bending one piece of fabric constituting the screen 7 and welding it in parallel with the bending line. It is also possible to form the joining piece 7b by superimposing a plurality of fabrics and welding them in parallel to the edges of the respective fabrics.

Further, although the details will be described later, the joint piece 7b is provided with a hole portion 11 (or a thin skin portion 12) that can be used as an insertion hole through which the elevating cord 3 hanging from the head box 1 can be inserted. The lower end of the elevating cord 3 inserted through the hole 11 (or the thin skin portion 12) is attached to the weight member (bottom rail in this example) 5.

Then, the operation code 9 is composed of, for example, an endless ball chain, and is hung on a pulley rotatably accommodated in an operation device (not shown). A plurality of recesses into which the ball portion of the ball chain of the operation code 9 is fitted are formed on the outer peripheral surface of the pulley.

A transmission gear composed of a plurality of gears is connected to the pulley in the head box 1, and the transmission gear is connected to each transmission clutch (not shown). Therefore, the transmission gear transmits the rotation of the pulley to the drive shaft (not shown) via each transmission clutch.

Further, in the head box 1, a plurality of take-up shafts (not shown) are provided with respect to the screen 7 and arranged in parallel. Then, the rotation of the drive shaft rotates the winding shaft rotatably supported in the head box 1, and the winding and rewinding of the elevating cord 3 raises and lowers the screen 7.

(Fabric with joint pieces)
FIG. 2A shows a schematic configuration of the fabric having the joint piece 7b of Example 1 according to the present invention constituting the screen 7. In the example shown in FIG. 2A, the fabric is welded continuously in the left-right direction of the screen 7 by using the line-shaped welding portion 10 substantially perpendicular to the left-right direction of the screen 7 as a unit welding pattern. The joint piece 7b of Example 1 is formed. Further, in the fabric having the joint piece 7b of Example 1 shown in FIG. 2A, a plurality of round holes 11 are formed in parallel with the plurality of welded portions 10 arranged in a line.

Then, when the fabric having the joint piece 7b of Example 1 shown in FIG. 2 (a) is used as the screen 7, a plurality of holes formed in the joint piece 7b are formed as shown in FIG. 3 (a). Any one of the parts 11 can be used as an insertion hole through which the elevating cord 3 can be inserted. As shown in FIG. 3A as a schematic cross-sectional view of the joint piece 7b, the thickness tb of the welded portion 10 is 30% or more and 90% with respect to the thickness ta of the joint piece 7b. It is formed by: It should be noted that 30% or less may be used as long as sufficient welding strength (that is, strength at which the upper and lower fabrics of the joint piece 7b do not separate) is obtained for the joint piece 7b.

On the other hand, FIG. 2B shows a schematic configuration of the fabric having the joint piece 7b of Example 2 according to the present invention constituting the screen 7. In the example shown in FIG. 2B, the fabric is welded continuously in the left-right direction of the screen 7 by using the line-shaped welding portion 10 substantially perpendicular to the left-right direction of the screen 7 as a unit welding pattern. Similar to Example 1, the joint piece 7b of Example 2 is formed. However, in the fabric having the joint piece 7b of Example 2 shown in FIG. 2B, a plurality of thin skin portions 12 are formed in parallel with the plurality of welded portions 10 arranged in a line. As shown in FIG. 3B, as a schematic cross-sectional view of the joint piece 7b, the thickness tb of the welded portion 10 is 30% or more and 90% or less with respect to the thickness ta of the joint piece 7b. The thickness tc of the thin skin portion 12 is formed at 1% or more and 20% or less with respect to the thickness ta of the joint piece 7b.

Then, when the fabric having the joint piece 7b of Example 2 shown in FIG. 2B is used as the screen 7, a plurality of thin skins formed on the joint piece 7b are formed as shown in FIG. 3B. Any one of the portions 12 can be used as an insertion hole by penetrating the elevating cord 3 so as to be inserted therethrough. That is, the thin skin portion 12 can be easily pierced by pressing the elevating cord 3 or the dedicated needle-shaped member.

In any of the joint pieces 7b of Examples 1 and 2, the pitch for continuously forming the plurality of welded portions 10 and the pitch for continuously forming the plurality of hole portions 11 or the thin skin portions 12 are arbitrary predetermined ones. can do.

For example, as shown in FIG. 4A, in the joint pieces 7b of Examples 1 and 2, when a plurality of welded portions 10 are formed at a pitch a, a plurality of thin skin portions 12 (or holes 11) are formed. It can be a different pitch b (≠ a). Further, as shown in FIG. 4B, in the joint pieces 7b of Examples 1 and 2, the plurality of thin skin portions 12 (or the hole portions 11) are provided in the same phase with respect to the pitch a of the plurality of welded portions 10. The same pitch b (= a) can also be used. Further, as shown in FIG. 4C, in the joint pieces 7b of Examples 1 and 2, the plurality of thin skin portions 12 (or the hole portions 11) have different phases with respect to the pitch a of the plurality of welded portions 10. However, the same pitch b (= a) can be used.

For the formation of the joint pieces 7b of Examples 1 and 2, each processing of the plurality of thin skin portions 12 (or holes 11) is performed simultaneously with or in parallel with each welding step of the plurality of welding portions 10. Can be done.

For example, as shown in FIG. 5A, a plurality of thin skin portions 12 are formed at the same time or in parallel with the processing of the welding step of the welding portion 10 (FIG. A1) in order to form the joining piece 7b which is the cord insertion region. (Or the hole 11) can be processed (A2 in the figure). When the hole portion 11 is formed as in the joint piece 7b of the first embodiment, the hole-drilling step may be a step using a dedicated hole-drilling device, or the surface of the fabric may be melted as an extension of the welding step. It can be a melting step of penetrating. Further, when the thin skin portion 12 is formed as in the joint piece 7b of Example 2, the thin skin forming step is a step using a dedicated thin skin forming device, and the surface of the fabric is extended as an extension of the welding step. It can be a melting step that melts and leaves a thin skin.

Then, in forming the joint piece 7b to be the cord insertion region, as shown in FIG. 5A, the processing of the welding step of the welding portion 10 (FIG. A1) is preceded, and the plurality of thin skin portions 12 (or the hole portions 11) are formed. (Fig. A2) is followed, and conversely, the processing of a plurality of thin skin portions 12 (or holes 11) is preceded by the processing (illustration A1), and the processing of the welding process of the welding portion 10 (illustration A2) is performed later. It can be processed efficiently. Further, in the case of forming a plurality of thin skin portions 12 as in the joint piece 7b of the second embodiment, the welding step can be combined as a part of the welding step of the welding portion 10, and the welding portion 10 and the thin skin portion 12 can be combined with each other. The formation can be easily realized at the same time.

Therefore, as in the comparative example according to the conventional technique shown in FIG. 5 (b), after the joint piece 7b is formed through the processing of the welding step of the welding portion 10 (FIG. A1), the shielding device (pleated screen in this example) is used. It is not necessary to set the hole position of the insertion hole 11 for each specification and perform a follow-up drilling process on the fabric, and as a result, it contributes to the reduction of the manufacturing cost.

In FIGS. 2 to 5 described above, the joining piece 7b is formed by the linearly shaped welding portions 10 substantially perpendicular to the left-right direction of the screen 7, and is circular in parallel with the plurality of linearly arranged welding portions 10. An example of forming the thin skin portion 12 (or the hole portion 11) is shown (see FIG. 6A), but the shape and size of the welded portion 10 and the hole portion 11 (or the thin skin portion 12) are also shown in the illustrated example. There is no need to limit it. In particular, the joint piece 7b of the fabric according to the present invention is formed on all or part of the thin skin portion 12 (or the hole portion 11) having an arbitrary shape (circle, elongated hole, square hole, etc.) arranged in a line. Alternatively, it can be connected to form a welded portion 10 having an arbitrary shape (circle, elongated hole, square hole, etc.).

For example, as shown in FIG. 6 (b), line-shaped welded portions 10 substantially parallel to the left-right direction of the screen 7 are lined up, and are rounded in parallel with the plurality of welded portions 10 arranged in a line. The thin skin portion 12 (or the hole portion 11) may be arranged to form the joint piece 7b.

Alternatively, as shown in FIG. 6 (c), square annular welded portions 10 substantially perpendicular to the left-right direction of the screen 7 are arranged in a line, and a thin skin portion 12 (or a hole) is formed inside the square annular welded portion 10. The joint piece 7b may be formed by disposing the portion 11).

Alternatively, as shown in FIG. 6D, a linear welding portion 10 having a linear shape substantially parallel to the left-right direction of the screen 7 and a square annular welding portion 10 substantially perpendicular to the left-right direction of the screen 7 are linearly formed. The thin skin portion 12 (or the hole portion 11) may be arranged inside the welded portion 10 having a square annular shape to form a joint piece 7b.

Alternatively, as shown in FIG. 6E, the linear welding portion 10 having a linear shape substantially parallel to the left-right direction of the screen 7 and the linear welding portion 10 having a linear shape substantially perpendicular to the left-right direction of the screen 7 are linear. The thin skin portion 12 (or the hole portion 11) may be arranged between the welded portions 10 having a substantially vertical linear shape adjacent to each other to form the joint piece 7b.

Alternatively, as shown in FIG. 6 (f), the screen 7 is connected to an oval-shaped thin skin portion 12 (or a hole portion 11) linearly arranged in the left-right direction of the screen 7 and is substantially connected to the left-right direction of the screen 7. A plurality (or one) welding portions 10 having a vertical linear shape may be arranged to form the joint piece 7b.

In particular, in the case of forming a plurality of thin skin portions 12, for example, in the formation of the joint piece 7b shown in FIGS. 6 (c) and 6 (f), as shown in FIGS. 7 (a) and 7 (b), respectively. It is possible to easily realize that the welding portion 10 and the thin skin portion 12 are formed at the same time by combining the welding step for forming the thin skin portion 12 as a part of the welding step of the welding portion 10 (Fig. A1). Therefore, the effect of reducing the manufacturing cost is further improved.

In the above-described example, an example in which the fabric according to the present invention is applied to the pleated screen of one embodiment has been described, but various fabrics having the joint piece 7b of each embodiment according to the present invention use this as a shielding material. It can be used as a shielding device. Hereinafter, application examples to various shielding devices will be described.

(Roman shade)
FIG. 8 is a perspective view showing a schematic configuration of a Roman shade configured as a shielding device according to an embodiment of the present invention. The roman shade is also called a daylighting curtain, in which shielding materials (two front and rear curtain fabrics 7F and 7R in this example) are suspended and supported from the frame 1A, and the lower ends of the curtain fabrics 7F and 7R are raised and lowered. By pulling up with 3, the curtain fabrics 7F and 7R can be individually raised or lowered to adjust the amount of lighting.

More specifically, in the Roman shade shown in FIG. 8, the curtain fabrics 7F and 7R are suspended and supported from the frame 1A, and the weight members 5F and 5R are embedded at the lower ends of the curtain fabrics 7F and 7R, respectively. Further, a plurality of elevating cords 3 hanging from the frame 1A on the back side of the curtain fabrics 7F and 7R are locked to hooks 25 attached near the lower ends of the curtain fabrics 7F and 7R.

Then, the drive shaft (not shown) in the frame 1A is rotated by operating the operation code 9 (for example, the ball chain), and the elevating cord 3 is wound or rewound based on the rotation of the drive shaft. Therefore, the curtain fabrics 7F and 7R can be raised and lowered independently.

Here, each of the curtain fabrics 7F and 7R is composed of a fabric having a joint piece 7b according to the present invention, either by folding one fabric and welding it, or by welding it so as to connect a plurality of fabrics. For example, in the curtain fabric 7F whose cross section is shown by enlarging and rearviewing with a broken line circle, the joining piece 7b of Example 1 extending in the vertical direction of the curtain fabric 7F (see FIG. 2A) is formed. Then, in the joint piece 7b of the first embodiment, a plurality of round holes 11 are formed in parallel with the plurality of welded portions 10 linearly arranged in the vertical direction. Further, the hanging position of the elevating cord 3 is at a position overlapping with the position of the joining piece 7b. A guide ring 20 (locking member) that can be attached to and detached from the outside is attached to any of the plurality of holes 11, so that the elevating cord 3 can be inserted and engaged. Such a guide ring 20 is arranged at a predetermined pitch in the vertical direction on the joint piece 7b, and the elevating cord 3 hanging from the frame 1A is inserted into each guide ring 20 and then locked to the hook 25. NS.

As a result, when the lifting cord 3 for raising and lowering the curtain cloth 7F is wound, the curtain cloth 7F can be lifted up based on the arrangement position of the guide ring 20.

In the example shown in FIG. 8, the joint piece 7b of Example 1 in which a plurality of holes 11 are formed in parallel with the plurality of welded portions 10 arranged in a line (see FIG. 2A) will be described as an example. However, it may be the joint piece 7b of Example 2 (see FIG. 2B) in which a plurality of thin skin portions 12 are formed in parallel with the plurality of welded portions 10 arranged in a line.

Further, the shapes and sizes of the welded portion 10 and the hole portion 11 (or the thin skin portion 12) need not be limited to the illustrated examples. In particular, the joint piece 7b according to the present invention is all or one around each of the thin skin portions 12 (or holes 11) having an arbitrary shape (circle, elongated hole, square hole, etc.) arranged in a line, as described above. It is possible that the welded portion 10 having an arbitrary shape (circle, elongated hole, square hole, etc.) is formed by connecting or connecting the portions.

Further, in the example shown in FIG. 8, an example in which the guide ring 20 is used has been described, but the elevating cord 3 is directly inserted and engaged using any of the plurality of holes 11 without using the guide ring 20. It can be the shape and size to be made.

As described above, the fabric having the joint piece 7b according to the present invention can be used as a shielding material (curtain fabric in this example). Therefore, unlike the comparative example according to the conventional technique shown in FIG. 5B described above, it is not necessary to perform the hole-drilling process on the fabric afterwards, and as a result, it contributes to the reduction of the manufacturing cost.

Further, since the joint piece 7b according to the present invention is provided with a large number of thin skin portions 12 (or holes 11) in advance, for example, by using a removable guide ring 20, the manufacturer or the user can voluntarily use the curtain. It will also be possible to adjust the position where the dough is tucked up.

FIG. 9 is a perspective view showing a schematic configuration of a Roman shade of another embodiment configured as a shielding device of one embodiment according to the present invention. In the Roman shade of the present embodiment, a shielding material (one piece of curtain cloth 7 in this example) is suspended and supported from the frame 1A, and the lower end portion of the curtain cloth 7 is pulled up by each elevating cord 3 to individually curtain. The amount of light collected can be adjusted by raising or lowering the dough 7.

More specifically, in the Roman shade shown in FIG. 9, the curtain cloth 7 is suspended and supported from the frame 1A, and the weight member 5 is embedded at the lower end of the curtain cloth 7. Further, the curtain fabric 7 is provided with three stages of joint pieces 7b, which are called shavers and which enclose rod-shaped bodies 26 extending in the left-right direction in this example. The plurality of elevating cords 3 hanging from the frame 1A are locked to the hooks 25 attached to the vicinity of the lower end portion of the curtain fabric 7 via the respective joint pieces 7b on the back side of the curtain fabric 7. There is.

Then, the drive shaft (not shown) in the frame 1A is rotated by operating the operation code 9 (for example, the ball chain), and the elevating cord 3 is wound or rewound based on the rotation of the drive shaft. Therefore, the curtain fabric 7 can be raised and lowered.

Here, the joint piece 7b that wraps the rod-shaped body 26 in the curtain cloth 7 is configured by folding and welding one piece of cloth or welding so as to connect a plurality of cloths, for example, a broken line circle. In the curtain fabric 7 whose cross section is shown in an enlarged / rear view, the joining piece 7b (see FIG. 2A) of the first embodiment extending in the left-right direction of the curtain fabric 7 is formed. Then, in the joint piece 7b of the first embodiment, a plurality of round holes 11 are formed in parallel with the plurality of welded portions 10 linearly arranged in the left-right direction. Further, the hanging position of the elevating cord 3 is at a position overlapping with the position of the joining piece 7b. The elevating cord 3 can be inserted and engaged with any one of the plurality of holes 11. The elevating cord 3 hanging from the frame 1A is inserted into the hole 11 of each joint piece 7b and then locked to the hook 25.

As a result, when the lifting cord 3 for raising and lowering the curtain cloth 7 is wound, the curtain cloth 7 can be lifted up based on the joint piece 7b that encloses the rod-shaped body 26.

In the example shown in FIG. 9, the joint piece 7b of Example 1 in which a plurality of holes 11 are formed in parallel with the plurality of welded portions 10 arranged in a line (see FIG. 2A) will be described as an example. However, it may be the joint piece 7b of Example 2 (see FIG. 2B) in which a plurality of thin skin portions 12 are formed in parallel with the plurality of welded portions 10 arranged in a line.

Further, the shapes and sizes of the welded portion 10 and the hole portion 11 (or the thin skin portion 12) need not be limited to the illustrated examples. In particular, the joint piece 7b according to the present invention is all or one around each of the thin skin portions 12 (or holes 11) having an arbitrary shape (circle, elongated hole, square hole, etc.) arranged in a line, as described above. It is possible that the welded portion 10 having an arbitrary shape (circle, elongated hole, square hole, etc.) is formed by connecting or connecting the portions.

Further, in the example shown in FIG. 9, an example in which the elevating cord 3 is directly inserted and engaged with the hole portion 11 (or the thin skin portion 12) has been described, but similarly to the example shown in FIG. 8, a plurality of guide rings 20 are provided. The elevating cord 3 may be engaged with the elevating cord 3 by installing it in any of the holes 11 of the above.

As described above, the fabric having the joint piece 7b according to the present invention can be used as a shielding material (curtain fabric in this example). Therefore, unlike the comparative example according to the conventional technique shown in FIG. 5B described above, it is not necessary to perform the hole-drilling process on the fabric afterwards, and as a result, it contributes to the reduction of the manufacturing cost.

(Vertical blind)
FIG. 10 is a perspective view showing a schematic configuration of a vertical blind configured as a shielding device according to an embodiment of the present invention. In the vertical blind, a large number of runners (not shown) are movably supported in the rail 1B, and slats 7B are suspended and supported by each runner via a suspension shaft 70. Then, by operating the operation code 9, each slat 7B can be transferred along the rail 1B, or each slat 7B can be rotated in the same phase to adjust the amount of lighting into the room.

Here, each slat 7B is formed by bending the lower end portion of one piece of fabric and welding so as to wrap the weight member 5, and in particular, the edge of the portion of each slat 7B to wrap the weight member 5. A joint piece 7b according to the present invention is formed in each portion.

That is, as shown by the dashed circle shown in FIG. 10, at the front edge near the lower end of the slat 7B, the joint piece 7b of Example 1 extending in the vertical direction of the slat 7B (see FIG. 2A) It is formed. Then, in the joint piece 7b of the first embodiment, a plurality of round holes 11 are formed in parallel with the plurality of welded portions 10 linearly arranged in the vertical direction. A guide ring 20 that can be attached to and detached from the outside is attached to any of the plurality of holes 11.

A bottom cord 5a is inserted and locked to the guide ring 20 of each slats 7B. As a result, the fluttering of each slat 7B is suppressed.

In the example shown in FIG. 10, the joint piece 7b of Example 1 in which a plurality of holes 11 are formed in parallel with the plurality of welded portions 10 arranged in a line (see FIG. 2A) will be described as an example. However, it may be the joint piece 7b of Example 2 (see FIG. 2B) in which a plurality of thin skin portions 12 are formed in parallel with the plurality of welded portions 10 arranged in a line.

Further, the shapes and sizes of the welded portion 10 and the hole portion 11 (or the thin skin portion 12) need not be limited to the illustrated examples. In particular, the joint piece 7b according to the present invention is all or one around each of the thin skin portions 12 (or holes 11) having an arbitrary shape (circle, elongated hole, square hole, etc.) arranged in a line, as described above. It is possible that the welded portion 10 having an arbitrary shape (circle, elongated hole, square hole, etc.) is formed by connecting or connecting the portions.

Further, in the example shown in FIG. 10, an example in which the guide ring 20 is used has been described, but the bottom cord 5a is directly inserted and locked by using any of the plurality of holes 11 without using the guide ring 20. The shape and size can be set.

As described above, the fabric having the joint piece 7b according to the present invention can be used as a shielding material (slat in this example). Therefore, unlike the comparative example according to the conventional technique shown in FIG. 5B described above, it is not necessary to perform the hole-drilling process on the fabric afterwards, and as a result, it contributes to the reduction of the manufacturing cost.

Further, since the joint piece 7b according to the present invention is provided with a large number of thin skin portions 12 (or holes 11) in advance, for example, by using a removable guide ring 20, the manufacturer or the user can voluntarily use each of them. The position at which the fluttering of the slats 7B is suppressed can also be adjusted.

In the example shown in FIG. 10, a detachable annular guide ring 20 is illustrated, but for example, a dedicated mounting member 50 as shown in FIG. 11A may be configured. The mounting member 50 shown in FIG. 11A has a pair of locking pieces 50a and 50b sandwiched from both sides with respect to the joining piece 7b, and on the facing surfaces of the pair of locking pieces 50a and 50b, respectively. Locking pins 50c and 50d are formed to insert and lock the thin skin portion 12 (or the hole portion 11) of the joint piece 7b. A U-shaped annular cord support portion 50e is formed on the base surfaces of the pair of locking pieces 50a and 50b by inserting and engaging the bottom cord 5a. Therefore, the mounting member 50 utilizes the elastic deformation of the pair of locking pieces 50a and 50b so that the locking pins 50c and 50d are inserted and locked with respect to the thin skin portion 12 (or the hole portion 11) of the joining piece 7b. The joint piece 7b can be attached to and detached from the outside. Such a mounting member 50 can be similarly used for the elevating cord 3 shown in FIG. 8 described above.

In the example shown in FIG. 10, the joint piece 7b of Example 1 in which a plurality of holes 11 are formed in parallel with the plurality of welded portions 10 arranged in a line (see FIG. 2A) will be described as an example. However, it may be the joint piece 7b of Example 2 (see FIG. 2B) in which a plurality of thin skin portions 12 are formed in parallel with the plurality of welded portions 10 arranged in a line.

Further, the shapes and sizes of the welded portion 10 and the hole portion 11 (or the thin skin portion 12) need not be limited to the illustrated examples. In particular, the joint piece 7b according to the present invention is all or one around each of the thin skin portions 12 (or holes 11) having an arbitrary shape (circle, elongated hole, square hole, etc.) arranged in a line, as described above. It is possible that the welded portion 10 having an arbitrary shape (circle, elongated hole, square hole, etc.) is formed by connecting or connecting the portions.

Further, in the example shown in FIG. 10, an example in which the guide ring 20 is used has been described, but the bottom cord 5a is directly inserted and locked by using any of the plurality of holes 11 without using the guide ring 20. The shape and size can be set.

As described above, the fabric having the joint piece 7b according to the present invention can be used as a shielding material (slat in this example). Therefore, unlike the comparative example according to the conventional technique shown in FIG. 5B described above, it is not necessary to perform the hole-drilling process on the fabric afterwards, and as a result, it contributes to the reduction of the manufacturing cost.

Further, since the joint piece 7b according to the present invention is provided with a large number of thin skin portions 12 (or holes 11) in advance, for example, by using a removable guide ring 20, the manufacturer or the user can voluntarily use each of them. The position at which the fluttering of the slats 7B is suppressed can also be adjusted.
