(first embodiment)

First, referring to FIG. 1 and FIG. 2, to hundred foldings with top cord 6U Yu the first embodiment of lower part cord 6L Curtain illustrates.Fig. 1 is the front view of the outline structure of the pleated blinds of display according to the first embodiment of the invention.In Fig. 2 (a), (b) is respectively front view and the side for the outline structure for being shown partially in pleated blinds according to the first embodiment of the invention View.

The top cord 6U of the pleated blinds of first embodiment is from 1 pendulous support of upper beam, and bent is zigzag, the curtain The lower end of cloth 6U is mounted on the upper surface of intermediate orbit 5.

Similarly the upper end of the bent lower part cord 6L for zigzag is installed on the lower surface of intermediate orbit 5, the lower part curtain The lower end of cloth 6L is installed on base track 7.

Both ends difference first and second operating rope of the pendulous support 9L, 9U of upper beam 1.First operating rope 9L carries out following behaviour Make：It will be for making halliard 3L under a plurality of (being two in this example) that base track 7 lifts draw from the rope export mouth 1a of upper beam 1 Go out, or is introduced into upper beam 1.Second operating rope 9U carries out operations described below：By a plurality of (this example for making intermediate orbit 5 lift In be two) upside halliard 3U draws from the rope export mouth 1b of upper beam 1, or is introduced into upper beam 1.

One end of each downside halliard 3L is connect via rope balancer (cord equalizer) 8L with the first operating rope 9L, The other end of each downside halliard 3L is imported into via the brake gear (not shown) for being set to upper beam 1 in upper beam 1, then via The support member 10 of the support pulley 10a suitably configured in place in upper beam 1 is diverted to lower section (in Fig. 2 (b)).Then, turn It is drawn to the other end of each downside halliard 3L to lower section from upper beam 1, is not interspersed in the reach through hole for being set to top cord 6U It hangs down in 4U but at the back side of top cord 6U via the back side of intermediate orbit 5, is arranged under by being interspersed in round The reach through hole 4L of portion cord 6L and penetrate through lower part cord 6L, and then connect with base track 7.

Therefore, when the first operating rope 9L of operation draws downside halliard 3L from upper beam 1, base track 7 is elevated, and is decontroled First operating rope 9L and if keeping the locking of the brake gear dynamic, downside halliard 3L can be prevented to be introduced into upper beam 1, will 7 pendulous support of base track is to desired locations.

In addition, the first operating rope 9L of operation draws downside halliard 3L from upper beam 1 slightly, make the lock of the brake gear After releasing, lets go to the first operating rope 9L and introduce downside halliard 3L in upper beam 1, it can be with by the weight of base track 7 Base track 7 is set to decline.

One end of each upside halliard 3U is connect via rope balancer 8U with the second operating rope 9U, each upside halliard 3U's The other end is imported into via the brake gear (not shown) for being set to upper beam 1 in upper beam 1, then via in upper beam 1 in appropriate place The support member of the support pulley of configuration is diverted to lower section.Then, it is diverted to the other end of each upside halliard 3U of lower section, is led to It crosses to be interspersed in be arranged and penetrates through top cord 6U in the reach through hole 4U of top cord 6U, and then connect with intermediate orbit 5.

Therefore, when the second operating rope 9U of operation draws upside halliard 3U from upper beam 1, intermediate orbit 5 is elevated, and is decontroled Second operating rope 9U and if keeping the locking of the brake gear dynamic, introducings of the upside halliard 3U into upper beam 1 can be prevented, By 5 pendulous support of intermediate orbit to desired locations.

In addition, the second operating rope 9U of operation draws upside halliard 3U from upper beam 1 slightly, make the lock of the brake gear After releasing, lets go to the second operating rope 9U and introduce upside halliard 3U in upper beam 1, it can be with by the weight of intermediate orbit 5 Intermediate orbit 5 is set to decline.

Intermediate orbit 5 is promoted to the underface of upper beam 1 by the pleated blinds of the first embodiment constituted like this, with Top cord 6U is in the state of folding, when base track 7 being allowed to decline, to show lower part curtain between upper beam 1 and intermediate orbit 5 States of the cloth 6L from 1 pendulous support of upper beam.

In addition, in the state of making base track 7 drop to lower limit, intermediate orbit 5 is made to drop on base track 7 When, it shows lower part cord 6L and is folded between intermediate orbit 5 and base track 7, top cord 6U is in upper beam 1 and intermediate orbit The state of pendulous support between 5.Thus, for example top cord 6U is daylighting fabric, when lower part cord 6L is light-proofness fabric, The degree of freedom of lighting quantity adjusting can be improved.

Then, base track 7 is made to drop to lower limit, make intermediate orbit 5 between upper beam 1 and base track 7 when, can be with It is adopted into soft light through for the top cord 6U of daylighting fabric.

In addition, when base track 7 is promoted to upper limit relieving, intermediate orbit 5 is not promoted and operates the first operating rope 9L and carries Base track 7 is risen, the state that top cord 6U and lower part cord 6L are folded between upper beam 1 and base track 7 can be showed.

In addition, as shown in (b) in Fig. 2, at the rear of upside halliard 3U, i.e. outside, spacing keeps rope 11 from upper beam 1 While hanging down, be mounted on intermediate orbit 5, spacing keeps rope 12 to hang down from intermediate orbit 5 and is installed on base track 7.

These spacing are kept in multiple circumferential support the rope 11a, 12a that are equally spaced respectively on rope 11,12, are worn respectively It is inserted with upside halliard 3U and downside halliard 3L.Then, intermediate orbit 5 is made to decline come when stretching top cord 6U, top curtain Cloth 6U is supported by supporting rope 11a, keeps the pleat line of top cord 6U at substantially equal intervals.Similarly, make base track 7 decline to draw When stretching lower part cord 6L, lower part cord 6L is supported by supporting rope 12a, keeps the pleat line of lower part cord 6L at substantially equal intervals.

But the pleated blinds of first embodiment as shown in Figure 1, in Fig. 2 shown in (b), downside halliard 3L is not It is interspersed in and is arranged among the reach through hole 4U of top cord 6U, but hang down from the back side of top cord 6U, be interspersed in setting In the reach through hole 4L of lower part cord 6L, penetrates through lower part cord 6L as a result, and be connected to base track 7.

That is, (a), (b) are shown in such as Fig. 2, it is only provided with reach through hole 4U on the cord 6U of top, reach through hole 4U is for interting The upside halliard 3U that end is connect with intermediate orbit 5.

Configuration is not needed on top cord 6U as a result, for the reach through hole of interspersed downside halliard 3L therefore light leakage can be inhibited, Further, the front view as shown in (a) in Fig. 2 is understood, upside halliard 3U and downside halliard 3L are set as one Item is linearly to improve beauty.

In addition, among the example of present embodiment, downside halliard 3L is not interspersed in Fig. 3 shown in (a) It is set in the reach through hole 4U of top cord 6U but hangs down composition from the back side of top cord 6U, in Fig. 3 shown in (b), It is not interspersed in the reach through hole 4U for being set to top cord 6U but the composition that hangs down before the cord 6U of the top, just In view, upside halliard 3U and downside halliard 3L are set to straight line shape so as to improve beauty.

Further, the pleated blinds of first embodiment shown in FIG. 1, in Fig. 2 shown in (a), respectively in top cord What is be arranged on 6U and lower part cord 6L, which is used for the size of the reach through hole 4U, 4L of halliard 3U and downside halliard 3L on the upside of interspersed, is Minimum size is only capable of respective one that accommodates upside halliard 3U and downside halliard 3L, without that can accommodate in addition to this Other rope spaces.Thus become the composition that can be reduced from reach through hole 4U, the 4L light leakage occurred.

Further, the respective section of the pleated blinds of first embodiment, upside halliard 3U and downside halliard 3L The area of the respective area of product and reach through hole 4U, 4L being both less than in previous scheme.It as a result, can be by top curtain when lifting The mobile regulation of cloth 6U and lower part cord 6L are preferred upper and lower directions to reduce top cord 6U and the lower part curtain when lifting Pleated blinds are integrally maintained beautiful kilter by the mobile deviation width (such as deviation of left and right directions) of cloth 6L.

More specifically, with reference to Fig. 2, fig. 4 to fig. 6 while comparative examples, to the cord of the pleated blinds of first embodiment The composition of surrounding illustrates.Composition around the cord of the pleated blinds of first embodiment, as shown in above-mentioned Fig. 2, one Aspect shows the ratio for being compared with the first embodiment of the present invention based on conventional art in (a) of Fig. 4, (b) Compared with example.Then, Fig. 5 and Fig. 6, which is respectively illustrated, carries out the composition of the composition of the first embodiment of the present invention and its comparative example Enlarged side view around the top cord of comparison.

First, with reference to (a) in Fig. 2, the pleated blinds of first embodiment of the invention, in bent top cord 6U In the state that (lower part cord 6L is also the same) is stretched, top cord 6U (lower part cord 6L is also the same) is from level with substantially 45 ° It tilts, the top cord 6U that the size of reach through hole 4U is made of the round hole of aperture D is as viewing surface charge level (diagram circle of dotted line In shape) when, similarly, the lower part cord 6L that the size of reach through hole 4L is made of the round hole of aperture D is as viewing surface charge level When (in diagram dashed circle), the halliard 3 of rope diameter (section diameter) d with circular cross-section becomes with minor axis d1 (=ropes The elliptical cross section planar of diameter d) and major diameter d2 (≈ d × √ 2).

Then, between the gap between upside halliard 3U and reach through hole 4U or downside halliard 3L and reach through hole 4L Gap be light leakage the main reason for, pleated blinds according to the first embodiment of the invention, gap is compared to conventional art Become smaller.The light leakage generated by reach through hole 4U, 4L is reduced as a result,.In addition, the pleated blinds structure of the first embodiment of the present invention Become：Via the reach through hole of the substantially central portion for the front-rear direction width for being respectively arranged at top cord 6U and lower part cord 6L 4U, 4L, in Fig. 2 shown in (b), upside halliard 3U only penetrates through top cord 6U, and downside halliard 3L only penetrates through lower part cord 6L.Among this example, being configured to upside halliard 3U and downside halliard 3L, (diagram is wide in the front-rear direction width of intermediate orbit 5 Degree 2 × approximate centre a) hangs down.

On the other hand, as shown in (a) in Fig. 4, the pleated blinds of the comparative example based on conventional art, equally bent upper In the state that portion cord 6U (lower part cord 6L is also the same) is stretched, top cord 6U (lower part cord 6L is also the same) from level with Substantially 45 ° of inclinations, such as the amplification visual angle as fabric face visual angle, the upside halliard 3U for interspersed rope diameter (section diameter) d ' And the size of the reach through hole 4U of downside halliard 3L, it is constituted with the round hole of aperture D ", for interspersed rope diameter (section diameter) d ' Downside halliard 3L reach through hole 4L size, constituted with the round hole of aperture D '.Herein, reach through hole 4U, 4L are distinguished When with aperture D ", D ' the top cord 6U constituted and lower part cord 6L respectively as viewing surface charge level (in diagram dashed circle), The halliard 3 of rope diameter (section diameter) d ' with circular cross-section becomes with minor axis d1 ' (=rope diameter d ') and major diameter d2 The elliptical cross section planar of (≈ d ' × √ 2).Then, the main reason for gap between halliard 3 and reach through hole 4U is light leakage, is based on The comparative example of previous scheme, it is found that its gap becomes larger compared with the pleated blinds of the first embodiment of the present invention shown in Fig. 2. Based on the comparative example of the previous scheme, it is configured to the substantially central portion via the front-rear direction width that is set to top cord 6U Each reach through hole 4U, in Fig. 4 shown in (b), the two of upside halliard 3U and downside halliard 3L penetrate through top cord 6U, downside Halliard 3L only penetrates through lower part cord 6L.Among this example, it is configured to upside halliard 3U and downside halliard 3L in intermediate orbit 5 The approximate centre of front-rear direction width (diagram width 2 × a) hang down.Therefore, the front-rear direction width (figure of intermediate orbit 5 Show that the substantially central portion of width 2 × a) is formed with the perforation road 5a of perforation downside halliard 3L.

But for using spacing keep rope 11,12 pleated blinds, there are spacing keep rope 11 supporting rope 11a with it is upper The fabric contact condition being in contact of portion cord 6U and the contactless state not being in contact both states, similarly, the presence of Spacing keeps the supporting rope 12a contact conditions being in contact with the fabric of top cord 6L of rope 12 and what is be not in contact non-connect Both states of the state of touching.Following representativeness illustrates top cord 6U.The branch that spacing is kept to rope 11 is shown in Fig. 5 The present invention when contact condition that support rope 11a is in contact in the position (diagram " contact point ") of the outside pleat line of top cord 6U The enlarged side view around the cord 6U of top that the composition of first embodiment and the composition of its comparative example are compared.In addition, Fig. 6 show by spacing keep the supporting rope 11a of rope 11 the position of the outside pleat line of top cord 6U not in contact with non-connect Around the top cord 6U that the composition of first embodiment of the invention when the state of touching and the composition of its comparative example are compared Enlarged side view.

At this point, in the composition of first embodiment of the present invention, for top cord 6U, (a) and Fig. 6 in Fig. 5 In shown in (a), for the only composition of the reach through hole 4U of the upside halliard 3U break-through aperture D of rope diameter (section diameter) d, no matter between Whether the fabric (fabric thickness sd) away from the supporting rope 11a and top cord 6U for keeping rope 11 is contact condition, reach through hole 4U with it is upper Gap in the front-back direction between the halliard 3U of side, than keeping rope 11 as spacing of the rope section with minor axis pd1 × major diameter pd2 The upper bending diameter bd in the front end (bending section) for being equally spaced multiple circumferential support rope 11a (circular cross-section diameter kd) It is small.Also the same for lower part cord 6L, tube spacing does not keep fabric (the fabric thickness of the supporting rope 12a and lower part cord 6L of rope 12 Sd whether it is) contact condition, the gap in the front-back direction between reach through hole 4L and upside halliard 3L, than having as rope section The spacing of minor axis pd1 × major diameter pd2 keeps being in be equally spaced multiple circumferential support rope 12a (circular cross-sections on rope 12 Diameter kd) front end (bending section) bending diameter bd smallers.

Further, the aperture D of reach through hole 4U of the present invention, the major diameter in the rope section than keeping rope 11 as spacing Pd2 is small.Similarly, the aperture D of reach through hole 4L of the present invention, the major diameter pd2 in the rope section than keeping rope 12 as spacing It is small.In addition, the gap in the front-back direction between reach through hole 4U and upside halliard 3U, than keeping rope 11 as bent spacing Rope section minor axis pd1 it is 2 times small.Similarly, the gap in the front-back direction between reach through hole 4L and downside halliard 3L, than The minor axis pd1's in the rope section as bent spacing holding rope 12 is 2 times small.In addition, upside halliard of the present invention The rope diameter d of 3U is path compared to any one of minor axis pd1 and major diameter pd2 in the rope section of rope 11 is kept as spacing. In the same manner, the rope diameter d of halliard 3L in downside of the present invention, compared to the minor axis in the rope section for keeping rope 12 as spacing Any one of pd1 and major diameter pd2 are path.Also, for the inhibition of light leakage, can with cord 6 from level with substantially 45 ° of inclined states compare, and the aperture D of reach through hole 4U of the present invention, 4L are：Make top and lower part cord 6U, 6L is such as It is projected in vertical or horizontal direction when being tilted from level with substantially 45 ° shown in (a) in (a) and Fig. 6 in Fig. 5 straight Diameter (45 ° of diameter projected Da) is respectively 2 times or less of upside and the rope diameter d of downside halliard 3U, 3L.

In the composition of first embodiment of the present invention, for the upside halliard for diameter (section diameter) d that only restricts The lower part cord 6L of the reach through hole 4L of 3L break-through aperture D is also the same.

That is, by such composition, it can be achieved that the light leakage that the reach through hole 4U of halliard 3U is generated on the upside of the break-through, and from The inhibition for the light leakage that the reach through hole 4L of halliard 3L is generated on the downside of break-through.

More specific Appropriate in representative diagram 5 in (a) and Fig. 6 in the example of top cord 6U shown in (a), on The rope diameter d of side halliard 3U isThe aperture D of reach through hole 4U isThe rope of rope 11 is kept to cut as spacing 0.8mm × 2.0mm that the minor axis pd1 × major diameter pd2 in face was respectively used in the past, the circumferential support rope 11a with circular cross-section Rope diameter (section diameter) kd be φ 0.2mm, the bending diameter bd of the front end (bending section) of supporting rope 11a is in above-mentioned contact condition It is about 3mm when being under about 1.5mm, contactless state when lower.In addition, the fabric thickness sd of cord 6 is to use about in the past 0.2mm。

In addition, it is also the same for lower part cord 6L, can be that the rope diameter d of downside halliard 3L isReach through hole The aperture D of 4L isIt is respectively previous use to keep the minor axis pd1 × major diameter pd2 in the rope section of rope 11 as spacing 0.8mm × 2.0mm, rope diameter (section diameter) kd of circumferential support rope 11a with circular cross-section isSupporting rope It is big when being under about 1.5mm, contactless state when the bending diameter bd of the front end (bending section) of 11a is under above-mentioned contact condition About 3mm.In addition, the fabric thickness sd of cord 6 is the about 0.2mm used in the past.

According to the present embodiment, it is being as rope diameter dUpside halliard 3U be interspersed in apertureReach through hole 4U in the state of, in Fig. 7 shown in fabric face visual angle shown in (a), reach through hole 4U with it is upper Gap between the halliard 3U of side, in the longitudinal direction for substantially 0.81mm (=D (1.8mm)-d2 (0.7mm × √ 2))~ The left and right 1.10mm (=D (1.8mm)-d1 (0.7mm)), it is (curved compared to the front end as the circumferential support rope 11a extended in its rear Pars convoluta) substantially 1.5mms of the bending diameter bd in above-mentioned contact condition, contactless state when substantially 3mm any one Become smaller.Therefore, it can be achieved that inhibition to the light leakage generated from reach through hole 4U, meanwhile, no matter which kind of situation supporting rope 11a is, Cannot invade reach through hole 4U (will not be hooked on), namely to fold or stretch top cord 6U and what action when lifting hindered Situation all disappears.

In addition, the aperture of reach through hole 4UMajor diameter pd2 than the rope section for keeping rope 11 as spacing (2.0mm) is small.Then, it is being as rope diameter dUpside halliard 3U be interspersed in aperture Reach through hole 4U in the state of, the gap between reach through hole 4U and upside halliard 3U, as described above, being in the longitudinal direction Substantially 0.81mm~1.10mm or so, the 2 of the minor axis pd1 (0.8mm) in the rope section than keeping rope 11 as bent spacing It is small again.It is thereby achieved that the inhibition to the light leakage generated from reach through hole 4U, no matter while bent spacing keep the rope 11 to be Which kind of situation cannot invade reach through hole 4U (will not be hooked on), i.e., be lifted to folding or stretching top cord 6U When action hinder situation all disappear.

Like this, it (is spacing holding in this example that reach through hole 4U, which is formed as the rope except the upside halliard 3U of interspersed object, 11 and its supporting rope 11a of rope) size that cannot invade.Similarly, reach through hole 4L is formed as the downside halliard 3L of interspersed object Except rope (keeping 12 and its supporting rope 12a of rope in this example for the spacing) size that cannot invade.

In addition, the aperture of reach through hole 4URope diameter d than upside halliard 3U is big, but because break-through 45 ° of diameter projected Da (2 ≈ 1.27mm of 1.8mm/ √) of hole 4U are formed as the rope diameter of upside halliard 3U2 times hereinafter, so the rope diameter d of upside halliard 3U is smaller, above-mentioned aperture D is smaller.In other words, this hair The rope diameter d of the bright upside halliard 3U being related to, minor axis pd1 and major diameter relative to the rope section for keeping rope 11 as spacing Any one of pd2 can be by path.Like this, the inhibition from the reach through hole 4U light leakages generated may be implemented, meanwhile, it maintains Relative to upside halliard 3U relative to the boring of reach through hole 4U, so the sectional area of upside halliard 3U and reach through hole 4U Area both of which is than previous scheme smaller.It is as a result, preferred upper and lower by the mobile regulation of top cord 6U when lifting To make the mobile deviation width (such as deviation of left and right directions) of top cord 6U when lifting become smaller, can be maintained as The whole beautiful kilter of pleated blinds.Also it is same for downside halliard 3L and reach through hole 4L.

(comparative example)

On the other hand, as shown in (b) in (b) in Fig. 5 and Fig. 6, in the composition involved by comparative example, upside halliard 3U and Each rope diameter d ' (equal with the minor axis d1 ' at fabric face visual angle shown in (a) in Fig. 4) of downside halliard 3L is The aperture D " of reach through hole 4U isThe aperture D ' of reach through hole 4L is 3.5mm.The rope section of rope 11 is kept as spacing Minor axis pd1 × major diameter pd2 is respectively 0.8mm × 2.0mm, the rope diameter (section of the circumferential support rope 11a with circular cross-section Diameter) kd isThe bending diameter bd of the front end (bending section) of supporting rope 11a, is about when under above-mentioned contact condition It is about 3mm when under 1.5mm, contactless state.In addition, the fabric thickness sd of cord 6 is about 0.2mm.In addition, involved by comparative example And composition in, only halliard 3L on the downside of engaging break-through in supporting rope 11a.

Therefore, relating to the comparative example, rope diameter d beUpside halliard 3U and downside halliard 3L wear It inserts in apertureReach through hole 4U in the state of, in Fig. 4 shown in fabric face visual angle shown in (a), Gap between reach through hole 4U and upside and downside halliard 3U, 3L, in the longitudinal direction substantially 1.61mm (=D ' (5.0mm) -2 × d2 ' (2 × 1.2mm × √ 2)) left and right~2.60mm (=D ' (5.0mm) -2 × d1 ' (2 × 1.2mm)), it is compared to For the circumferential support rope 11a extended in its rear front end (bending section) bending diameter bd in above-mentioned contact condition substantially 1.5mm big.

Therefore, relating to the comparative example, rope diameter d beDownside halliard 3L be interspersed in apertureReach through hole 4L in the state of, in Fig. 4 shown in fabric face visual angle shown in (a), reach through hole 4L and downside Gap between halliard 3L, in the longitudinal direction substantially 1.80mm (=D ' (3.5mm)-d2 ' (1.2mm × √ 2))~ The left and right 2.30mm (=D ' (3.5mm)-d1 ' (1.2mm)), it is (more curved than the front end as the circumferential support rope 12a extended in its rear Pars convoluta) substantially 1.5mms of the bending diameter bd in above-mentioned contact condition it is big.

Therefore, from reach through hole 4U, the light leakage that 4L is generated becomes larger, supporting rope 11a can invade reach through hole 4U, supporting rope 12a can Reach through hole 4L (being hooked on sometimes) is invaded, i.e., to folding or stretching top cord 6U or lower part cord 6L and action when lifting is produced It is raw to hinder.

In addition, the aperture of the reach through hole 4U involved by comparative exampleAnd the aperture of reach through hole 4LMinor axis pd1 × major diameter pd2 than the rope section for keeping rope 11,12 as bent each spacingIt is 2 times big.Moreover, the gap between reach through hole 4U and upside and downside halliard 3U, 3L, as described above preceding It is substantially 1.61mm~2.60mm or so in rear direction, the gap between reach through hole 4L and downside halliard 3L exists as described above It is substantially 1.80mm~2.30mm or so on front-rear direction, than the short of section of restricting for keeping rope 11,12 as bent spacing 2 times of diameter pd1 (0.8mm) are big.Therefore, from reach through hole 4U, the light leakage that 4L is generated becomes larger, and bent each spacing keeps rope 11, 12 become that reach through hole 4U, 4L (being hooked on sometimes) can be invaded respectively, i.e., to folding or stretching top cord 6U or lower part cord 6L Lifting when action generate obstruction.

Further, the aperture of the reach through hole 4U involved by comparative exampleAnd the aperture of reach through hole 4LIn Fig. 5 in (b) and Fig. 6 shown in (b), 45 ° of diameter projected Da " ((5.0mm/ √ 2 of reach through hole 4U ≈ 3.54mm) ratio upside halliard 3U rope diameter2 times of biggers, similarly, this 45 ° of reach through hole 4L The rope diameter of diameter projected Da ' (2 ≈ 2.47mm of 3.5mm/ √) ratios downside halliard 3L2 times of biggers, because This, from reach through hole 4U, the light leakage that 4L is generated becomes larger, corresponding to the sectional area and difference of upside halliard 3U and downside halliard 3L Each reach through hole 4U, both areas of 4L are than embodiment bigger of the present invention, top cord 6U when lifting or lower part curtain The mobile deviation width (such as deviation of left and right directions) of cloth 6L is opposite to become larger.

As above, Fig. 1 and the pleated blinds of first embodiment shown in Fig. 2, respectively in top cord 6U and lower part cord 6L The size of the reach through hole 4U, 4L for only interspersed upside halliard 3U and downside halliard 3L of upper setting are very small dimensions, only Respective one of upside halliard 3U and downside halliard 3L, the sky of no other ropes that can be accommodated in addition to this etc. can be accommodated Between, it is to make its raising instead so will not hinder to lift performance, the light leakage generated from reach through hole 4U, 4L can be reduced.

Further, the sectional area of the pleated blinds of first embodiment, upside halliard 3U and downside halliard 3L, and it is each From corresponding each reach through hole 4U, the both sides of the area of 4L are than previous scheme smaller, therefore, can be by top cord when lifting The mobile regulation of 6U or lower part cord 6L are preferred upper and lower directions to reduce top cord 6U or the lower part cord when lifting The mobile deviation width (such as deviation of left and right directions) of 6L, pleated blinds are integrally maintained to beautiful kilter, and (raising is dynamic State design).

Then, it does not need to configure the reach through hole of interspersed downside halliard 3L in top cord 6U so can inhibit light leakage, Moreover, the front view as shown in (a) in Fig. 2 is understood, by the way that upside halliard 3U and downside halliard 3L is arranged For straight line shape, can improve beautiful (improving Static Design).

In addition, in the example of top cord 6U as shown in (a) in (a) in Fig. 5 and Fig. 6, it is configured to spacing and keeps on rope 11 Circumferential support rope 11a on only engaging be interspersed with upside halliard 3U, but the variation 1 as shown in (a) in Fig. 7, in top curtain Snap-latch piece 61 is formed by welding etc. in the back side of cloth 6U, the reach through hole 62 to being set to the snap-latch piece 61 interts to be risen into downside Drop rope 3L keeps rope 11 so as to not use spacing.Thus, it is possible to which completely eliminating spacing keeps 11a pairs of rope 11 or supporting rope The intrusion of reach through hole 4U.

In addition, the variation 2 as shown in (b) in Fig. 7, is configured under interting to the reach through hole 62 for being set to snap-latch piece 61 Side halliard 3L, spacing keep engaging interspersed upside halliard 3U and downside halliard 3L in the circumferential support rope 11a on rope 11 The two.Thus, it is possible to prevent the bending diameter bd of supporting rope 11a unnecessarily minor axis, can further inhibit to support Intrusions of the rope 11a to reach through hole 4U.

In addition, the variation 3 as shown in (c) in Fig. 7, or following to constitute：To being set to the break-through of snap-latch piece 61 Hole 62 is interted into downside halliard 3L, and spacing keeps only engaging interspersed downside halliard 3L in the circumferential support rope 11a on rope 11. Thus, it is possible to make it possible short and smallization of supporting rope 11a, further inhibit intrusions of the supporting rope 11a to reach through hole 4U.

(second embodiment)

(other embodiment)

Make further development from the embodiment and variation of above-mentioned each embodiment, can also be following embodiment party Formula.Make downside halliard 3L when the back side of intermediate orbit 5 is hung down round, in order to mitigate the interference resistance for intermediate orbit 5 Power or the lifting performance for improving lower part cord 6L make downside halliard 3L more linearly engage with lower part cord 6L and hang down Embodiment.

For example, the variation by first embodiment as representative, example 1~6 is simply illustrated in Figure 12 to Figure 14 Embodiment, illustrate in sequence below.

(example 1)

First, in the embodiment of example 1 as shown in (a) in Figure 12, the upside for making top cord 6U be lifted Halliard 3U is interspersed in the reach through hole 4U of top cord 6U, and the downside halliard 3L that lower part cord 6L is lifted is made not intert In the reach through hole 4U of top cord 6U, but it is interspersed in round before the cord 6L of lower part via the back side of intermediate orbit 5 In the reach through hole 4L formed at the position that rear direction width midway rearward deviates.

The reach through hole 4U of top cord 6U in Figure 12 in the embodiment of example 1 shown in (a), is not limited It is fixed, it is configured in this example：On top, (every layer is each layer for being bent to multilayer in zigzag in the up-down direction of cord 6U Japanese " く " character segment) on, it is formed in the center of the front-rear direction width of top cord 6U, makes upside halliard 3U in mid-rail The approximate centre of the front-rear direction width (2 × a of diagram width) in road 5 hangs down.

On the other hand, for the reach through hole 4L of the lower part cord 6L in the embodiment of example 1 shown in (a) in Figure 12, structure Become：Each layer for being bent to multilayer in zigzag in the up-down direction of cord 6L in lower part (every layer is Japanese " く " character segment) On, it is formed in from the position that the front-rear direction width midway of lower part cord 6L rearward deviates, that is, each layer of lower part cord 6L In it is in the front-back direction away from the position that front is length b ', away from rear be length c ' (<B ') position on, in the hole of reach through hole 4L The heart is located at this.In addition, downside halliard 3L is away from the position that front is length b, away from rear in the in the front-back direction of intermediate orbit 5 Length c (<B) it hangs down at position.

In addition, in fig. 12 in the embodiment of example 1 shown in (a), make that top cord 6U and lower part cord 6L's is front and back The fabric width in direction is same, the front and back of the position O and lower part cord 6L of the front-rear direction width midway of top cord 6U It is equivalent locations to the position O ' of width midway, to become when top cord 6U and lower part cord 6L is separately folded, top Cord 6U and lower part cord 6L in the longitudinal direction almost without departing from composition.

Like this, rearward inclined from the front-rear direction width midway of lower part cord 6L by being interspersed in downside halliard 3L It is formed by the position of shifting in reach through hole 4L, makes downside halliard 3L when the back side of intermediate orbit 5 is hung down round, it can be with So that downside halliard 3L is more linearly engaged and is hung down with lower part cord 6L, the interference resistance for intermediate orbit 5 can be mitigated Power or the lifting performance for improving lower part cord 6L.

(example 2)

Then, in fig. 12 in the embodiment of example 2 shown in (b), the upside for making top cord 6U be lifted Halliard 3U is interspersed in the reach through hole 4U of top cord 6U, makes lower part cord 6L than top cord 6U towards more rearward offset On the basis of, for making the downside halliard 3L that lower part cord 6L is lifted not be interspersed in the reach through hole 4U of top cord 6U In, but it is interspersed in wearing for the front-rear direction width midway for being formed in lower part cord 6L round via the back side of intermediate orbit 5 In through-hole 4L.

The reach through hole 4U of top cord 6U in Figure 12 in the embodiment of example 2 shown in (b), is not limited It is fixed, it is configured in this example：On top, (every layer is each layer for being bent to multilayer in zigzag in the up-down direction of cord 6U Japanese " く " character segment) on, it is formed in the center of the front-rear direction width of top cord 6U, makes upside halliard 3U in mid-rail The approximate centre of the front-rear direction width (2 × a of diagram width) in road 5 hangs down.

On the other hand, for the reach through hole 4L of the lower part cord 6L in the embodiment of example 2 shown in (b) in Figure 12, structure Become：Each layer for being bent to multilayer in zigzag in the up-down direction of cord 6L in lower part (every layer is Japanese " く " character segment) On, it is formed in the front-rear direction width midway of lower part cord 6L, that is, the hole center of reach through hole 4L is located at each layer of lower part cord 6L In front-rear direction width midway (being the position of length a ' apart from front and back).

Wherein, it is configured in the embodiment of example 2 shown in (b) in fig. 12：Make top cord 6U and lower part cord 6L Fabric width in the front-back direction be same, meanwhile, the position O ' of the front-rear direction width midway of lower part cord 6L is from top curtain The position O of the front-rear direction width midway of cloth 6U rearward deflected length d (>0), halliard 3L in downside is away from intermediate orbit 5 The position of length b in front in the front-back direction, away from rear length c (<B) it hangs down at position.Become as a result, and top is being separately folded The composition for allowing top cord 6U and lower part cord 6L to deviate in the longitudinal direction when cord 6U and lower part cord 6L.

Like this, by making lower part cord 6L be the composition relatively deviated towards the rear relative to top cord 6U, under making Side halliard 3L when the back side of intermediate orbit 5 is hung down round, can make downside halliard 3L more linearly with lower part curtain Cloth 6L engages and hangs down, and can mitigate the interference drag to intermediate orbit 5 or improve the lifting performance of lower part cord 6L.

(example 3)

Then, in fig. 13 in the embodiment of example 3 shown in (a), the upside for making top cord 6U be lifted Halliard 3U is interspersed in the reach through hole 4U of top cord 6U, and lower part cord 6L is formed as width in the longitudinal direction more than upper Portion cord 6U, and the downside halliard 3L for making lower part cord 6L lift is not interspersed in the reach through hole 4U of top cord 6U, and It is to be interspersed in the reach through hole formed at the front-rear direction width midway of lower part cord 6L round via the back side of intermediate orbit 5 In 4L.

The reach through hole 4U of top cord 6U in Figure 13 in the embodiment of example 3 shown in (a), is not limited It is fixed, it is configured in this example：On top, (every layer is each layer for being bent to multilayer in zigzag in the up-down direction of cord 6U Japanese " く " character segment) on, it is formed in the center of the front-rear direction width of top cord 6U, makes upside halliard 3U in mid-rail The approximate centre of the front-rear direction width (2 × a of diagram width) in road 5 hangs down.

On the other hand, for the reach through hole 4L of the lower part cord 6L in the embodiment of example 3 shown in (a) in Figure 13, structure Become：Each layer for being bent to multilayer in zigzag in the up-down direction of cord 6L in lower part (every layer is Japanese " く " character segment) On, it is formed in from the position that the front-rear direction width midway of lower part cord 6L rearward deviates, that is, the hole center of reach through hole 4L In the front-back direction on each layer of lower part cord 6L away from the position that front is length b ', away from rear be length c ' (<B ') At position.

In particular, in fig. 13 in the embodiment of example 3 shown in (a), lower part cord 6L is formed as on front-rear direction Width is more than top cord 6U.Therefore, the downside halliard 3L for making lower part cord 6L lift, can be from top cord 6U's Rear via intermediate orbit 5 the back side without hang down deviously until lower part cord 6L rear.

In addition, being configured in the embodiment of example 3 shown in (a) in fig. 13：Lower part cord 6L is in the longitudinal direction Width is more than top cord 6U, on this basis, make the position of the position O ' of the front-rear direction width midway of lower part cord 6L from At the position O of the front-rear direction width midway of top cord 6U rearward deflected length d (>0), halliard 3L in downside is away from centre The position of the length b in front in the front-back direction of track 5, away from rear length c (<B) it hangs down at position.
