Hereinafter, with reference to Fig. 7, the action of the operation panel 6 to second embodiment more specifically illustrates.First, reference (a) in Fig. 7, operation panel 6 is supported for：Can be using fulcrum 16 as rotary shaft with respect to operation pulley 10 and rolling tube 9 Rotated, and, when underbeam 5 remains static in lower position, centre position and upper limit position respectively, by certainly Weigh (cord 4, underbeam 5, operation panel 6, gripper shoe 8, the weight of support shaft 7) and direction is applied to operation panel 6 and so that before and after's cord 4 is pasted The torque of tight direction, i.e. front face side (being clockwise in (a) of Fig. 7).And, operating rope 3 is to be arranged at support member Hang down on the basis of rope guide portion 14 on 2a.

Next, with reference to (b) in Fig. 7, when the state being located at lower position or centre position from such as underbeam 5 start right When operating rope 3 is operated and so that underbeam 5 is increased, cord 4 is wound onto on rolling tube 9.Now, restricted by operating rope 3 and draw Leading portion 14, for fulcrum, torque is applied to support shaft 7, thus driving operation panel 6 to make pendular movement, thus making the behaviour of double-deck cord 4 Interval d1 when interval d2 when making is more than static.Therefore, in lifting operations, the relative movement of double-deck cord 4 is without producing Friction or the generation friction of the part stage only in lifting process or frictional force weaken, thus there is not damage cord 4 Probability.

Similarly, with reference to (c) in Fig. 7, when from such as underbeam 5 is centrally located or state of upper limit position start right When operating rope 3 is operated and so that underbeam 5 is declined, the cord 4 on rolling tube 9 declines.Now, by operating rope 3 with Rope guide portion 14 applies torque for fulcrum to support shaft 7, thus driving operation panel 6 to make pendular movement, thus makes double-deck cord 4 Operation when interval d3 be more than static when interval d1.Therefore, in step-down operation, the relative movement of double-deck cord 4 without Produce friction or the part stage only in lifting process produces friction or frictional force weakens, thus there is not damage curtain The probability of cloth 4.

Therefore, in the roller shutter 1 of second embodiment, in descending operation, operation panel is made by the pulling force of operating rope 3 6 are rotated so that double-deck cord 4 with the state relative movement that is separated from each other without produce friction (or, even if producing Friction, friction is also weakened), thus not there is a possibility that to damage cord 4.In addition, when remaining static, operating rope 3 Lose tension force, operation panel 6 direction in the presence of the deadweight of cord 4 grade makes the close direction of double-deck cord 4 rotate, accordingly, it is capable to So that the interval of double-deck cord 4 is reduced or so that double-deck cord 4 is adjacent to such that it is able to improve the transmittance section 4b making cord 4 and screening Light portion 4a is completely overlapped and is formed as light-proofness during shading status.

Especially in the roller shutter 1 of second embodiment, compared with first embodiment, can reduce based on operation panel 6 Pendular movement depending on roller shutter 1 before and after width installation space.In addition, by setting rope guide portion 14, downward During pull operation rope 3, operation panel 6 and gripper shoe 8 can be made towards making the detached direction of double-deck cord 4 rotate.

[the 3rd embodiment]

Next, the composition of the roller shutter 1 third embodiment of the invention being related to reference to Fig. 8 to Figure 12 illustrates.Fig. 8 It is the front view of the schematic configuration of roller shutter 1 representing that third embodiment of the invention is related to, Fig. 9 is to represent the present invention the 3rd enforcement The exploded perspective view of the schematic configuration around operation panel 6 in the roller shutter 1 that mode is related to.In addition, (a), (b), (c) in Figure 10 It is the figure that the action of operation panel 6 in the roller shutter 1 that third embodiment of the invention is related to is described.(a), (b) in Figure 11 is to say The figure of the action during operation of operation panel 6 in the roller shutter 1 that bright third embodiment of the invention is related to.(a), (b) in Figure 12 It is that operation panel 6 in the roller shutter 1 in the way of being compared with comparative example, third embodiment of the invention being related to is illustrated Figure.In addition, for the component parts playing with first embodiment phase same-action, giving identical reference marks.

Except operation pulley 10, support member 2a (and support member 2b) and operation panel 6 (and gripper shoe 8) form not Outside this point, the composition of roller shutter 1 of the 3rd embodiment shown in Fig. 8 is roughly the same with the composition of first embodiment. Therefore, in the following description, mainly support member 2a and operation panel 6 of the 3rd embodiment is illustrated.

With reference to Fig. 9, the operation panel 6 of the 3rd embodiment and concrete composition about are illustrated.In rolling tube 9 At right part, in the same manner as first embodiment, rolling tube 9 is supported for can be with respect to consolidating of extending from support member 2a Dead axle 11 is rotated.Operation pulley 10 is provided with through hole, using fixing axle 11 as rotary shaft.Rolling tube 9 can be with behaviour Make the rotation of pulley 10 and rotated.

The operation panel 6 of the 3rd embodiment shape in elongate shape, and it is arranged on operation pulley 10 and support member 2a Between near outside position at, to avoid fixing axle 11, and, be provided with operation panel 6 for from support member 2a extend The rotary shaft hole portion 27 that the fulcrum 16 going out is inserted, so that operation panel 6 carries out pendular movement using fulcrum 16 as rotary shaft.With One embodiment similarly, is provided with hole portion 22 in the section below of operation panel 6, will be with the holding member 21 using rivet etc. The one end of the support shaft 7 extending between support member 2a, 2b is arranged on operation panel 6.

The shape of the gripper shoe 8 of present embodiment is also roughly the same with the operation panel 6 of present embodiment.Support shaft 7 both may be used Can be rotated with respect to operation panel 6 and gripper shoe 8 it is also possible to be installed to be can not be with respect to operation panel 6 with being installed to be Rotated with gripper shoe 8.Alternatively, it is also possible to be configured to：Operation panel 6 and gripper shoe 8 are provided with fulcrum 16, and in supporting part Rotary shaft hole portion 27 is respectively equipped with part 2a, 2b.

The operation panel 6 of the 3rd embodiment and gripper shoe 8, can be using fulcrum 16 as rotary shaft with respect to operation pulley 10 and rolling tube 9 rotated.The position of pendular movement is according to positioned at the curtain in support shaft 7 and rolling tube 9 by suspension strut Depending on the deadweight of underbeam 5 grade of the lower end of cloth 4.

The operation panel 6 of the 3rd embodiment so constituting and gripper shoe 8 can be with respect to operation pulley 10 and rolling tubes 9 Rotated, and in the presence of the deadweight of cord 4 etc., pendular movement can be carried out using fulcrum 16 as rotary shaft.

The top of support member 2a is configured with rope cover 20 (not shown), in case the operating rope 3 being hung around on operation pulley 10 Come off.In addition, rope cover 20 can also be made up of the miscellaneous part being fixed in fixing axle 11.

And, on the operation panel 6 of the 3rd embodiment, it is not provided with two rope guide portion as in the first embodiment 12、13.Replace, support shaft 7 is configured the front face side in cord 4, and so that operating rope 3 is passed through from the rear side of support shaft 7. Therefore, in the present embodiment, support shaft 7 is configured to the work(possessing the rope guide portion 12,13 being equivalent to first embodiment Energy.In addition, the bottom of support member 2a is provided with rope guide portion 14, and operating rope 3 hangs down from the front face side of this rope guide portion 14. That is, from the ring-type operating rope 3 operating pulley 10 to hang down after bypassing the outside of support shaft 7, in the guiding of rope guide portion 14 Under hang down (with reference to Fig. 8) from the top of rope guide portion 14.In addition, in addition to being not provided with rope guide portion 14 this point, supporting part The shape of part 2b is roughly the same with the shape of support member 2a.

Therefore, the operation panel 6 of the 3rd embodiment is also configured to：When operating to operating rope 3, to allow to phase The mode that the interval of the double-deck cord 4 of movement is increased carries out pendular movement.Especially, operation panel 6 so that rolling tube 9 with support Between position relationship when position relationship when static for the position relationship between axle 7 and operation, the mode of change carries out pendulum fortune Dynamic.And, operation panel 6 is configured to：Make double-deck cord 4 operation when interval be more than static when interval.

Hereinafter, with reference to Figure 10 to Figure 12, the action of the operation panel 6 to the 3rd embodiment more specifically illustrates.First First, with reference to (a) in Figure 10, operation panel 6 is supported for：Can be using fulcrum 16 as rotary shaft with respect to operation pulley 10 He Rolling tube 9 is rotated, and, when underbeam 5 remains static in lower position, by deadweight (cord 4, underbeam 5, behaviour Make plate 6, gripper shoe 8, the weight of support shaft 7) and operation panel 6 is applied towards the direction making before and after's cord 4 be adjacent to, i.e. front face side The torque of (being clockwise in (a) of Figure 10).And, the rope guide portion 14 to be arranged in support member 2a for the operating rope 3 On the basis of and hang down.

When this underbeam 5 remains static in lower position, double-deck cord 4 is in position that is close to each other or being adjacent to The interval of the double-deck cord 4 when (being spaced apart d1 of double-deck cord 4) immobilizes.Therefore, it is possible to make the transmittance section of double-deck cord 4 4b and light shielding part 4a stagger and be formed as semi-transparent light state or make cord 4 transmittance section 4b and light shielding part 4a completely overlapped and Be formed as shading status, enable in particular to improve light-proofness during shading status.In addition, from the light-proofness side improving double-deck cord 4 Set out in face, preferably with cord 4 under lower limit state, from the position that rolling tube 9 and support shaft 7 hang down, overlap is joined in the longitudinal direction The mode put, the upper end of cord 4 is arranged on rolling tube 9 and support shaft 7.

In addition, with reference to (b) in Figure 10, when this underbeam 5 is in resting state in centre position, with underbeam 5 under Extreme position moves to upper limit position, and coil diameter R of the cord 4 on rolling tube 9 constantly increases, by the deadweight of cord 4 grade And the cord 4 hanging down be positioned against outdoor side shifting, but, before reaching specified altitude, the interval of double-deck cord 4 reduces Or the position constant (interval d1 ' the ≈ d1 of double-deck cord 4) that double-deck cord 4 is adjacent to each other.Therefore, it is located at centre in cord 4 When at the position below of position, the transmittance section 4b and light shielding part 4a of double-deck cord 4 can be made to stagger and be formed as semi-transparent light state, Or the transmittance section 4b and light shielding part 4a that make cord 4 are completely overlapped and be formed as shading status, enable in particular to improve shading status When light-proofness.

In addition, with reference to (c) in Figure 10, when this underbeam 5 remains static in upper limit position, wound on rolling tube 9 On coil diameter R of cord 4 increase to maximum, the position of the cord 4 being hung down by the deadweight of cord 4 grade is further to outside Mobile, but, in this condition, so that the position that the interval of double-deck cord 4 reduces also is immobilized.

But, in this condition, because cord 4 is in open mode in itself, accordingly, it would be desirable to double-deck cord when noting static 4 close state, in case produce problem at practical aspect.

Next, with reference to (a) in Figure 11, when the state being located at lower position from such as underbeam 5 starts to operating rope 3 When being operated and so that underbeam 5 is increased, cord 4 is wound onto on rolling tube 9.Now, by operating rope 3 guide portion 14 of restricting it is Fulcrum and to support shaft 7 apply torque, thus driving operation panel 6 to make pendular movement, thus make double-deck cord 4 operation when between Interval d1 when d2 is more than static.Therefore, in lifting operations, the relative movement of double-deck cord 4 without produce friction or Part stage friction only in lifting process or frictional force weaken, thus not there is a possibility that to damage cord 4.

Similarly, with reference to (b) in Figure 11, when from such as underbeam 5 is centrally located or upper limit position at state open When beginning operating rope 3 is operated and so that underbeam 5 is declined, the cord 4 on rolling tube 9 declines.Now, by operating rope 3 apply torque as fulcrum to support shaft 7 with guide portion 14 of restricting, thus driving operation panel 6 to make pendular movement, thus make Double-layer curtain Interval d1 when interval d3 during the operation of cloth 4 is more than static.Therefore, in step-down operation, the relative movement of double-deck cord 4 and not Friction can be produced or the part stage only in lifting process produces friction or frictional force weakens, thus there is not damage The probability of cord 4.

Here, in order to illustrate to the points for attention in the pendular movement of the operation panel 6 of the 3rd embodiment, Figure 12's Show different from the present embodiment shown in (a) in Figure 12 in (b), and the fulcrum 16 of operation panel 6 is configured near solid Comparative example at the position of dead axle 11.In present embodiment shown in (a) in fig. 12, when underbeam 5 is in lower position During resting state, by suspension strut in the presence of the deadweight of the cord 4 in support shaft 7 and rolling tube 9 etc., double-deck cord 4 The interval being in the double-deck cord 4 during position that is close to each other or being adjacent to (the interval d1 of double-deck cord 4) immobilizes.

On the other hand, in the comparative example shown in (b) in fig. 12, due to fulcrum 16 being configured closer to fixing axle At 11 position, thus the interval D of double-deck cord 4 becomes big (D ＞ d1), thus unsatisfactory.Therefore although fulcrum 16 preferable Spacing between the diameter of position and support shaft 7 or rolling tube 9 and support shaft 7 and rolling tube 9 is relevant, however, it is preferred to below Determine on the basis of when beam 5 remains static in lower position, so that the interval of double-deck cord 4 reduces or double-deck cord 4 It is adjacent to each other.

Therefore, in the roller shutter 1 of the 3rd embodiment, in descending operation, operation panel is made by the pulling force of operating rope 3 6 are rotated so that double-deck cord 4 with the state relative movement that is separated from each other without produce friction (or, even if producing Friction, friction is also weakened), thus not there is a possibility that to damage cord 4.In addition, when remaining static, operating rope 3 Lose tension force, operation panel 6 direction in the presence of the deadweight of cord 4 grade makes the close direction of double-deck cord 4 rotate, accordingly, it is capable to So that the interval of double-deck cord 4 is reduced or so that double-deck cord 4 is adjacent to each other such that it is able to improve the transmittance section 4b making cord 4 Completely overlapped with light shielding part 4a and be formed as light-proofness during shading status.

Especially in the roller shutter 1 of the 3rd embodiment, configure side and indoors indoors due to being formed support shaft 7 Side-lower swings the hardened structure of (swing), therefore, compared with first embodiment, can reduce the pendulum fortune based on operation panel 6 The installation space of width before and after roller shutter 1 depending on dynamic.

[the 4th embodiment]

Next, with reference to Figure 13 to Figure 14, for the present invention the 4th embodiment party of the variation as first embodiment The composition of the roller shutter 1 that formula is related to illustrates.Figure 13 is the operation panel representing in the roller shutter 1 that four embodiment of the invention is related to The exploded perspective view of the schematic configuration around 6.

In addition, (a), (b), (c) in Figure 14 is the operation panel illustrating in the roller shutter 1 that four embodiment of the invention is related to The figure of 6 action.In addition, for the component parts playing with first embodiment phase same-action, giving identical reference marks.

Except operation panel 6 and operation pulley 10 between be provided with winding gear mechanism (driving gear 31, travelling gear 32, Driven gear 33) outside, the composition of roller shutter 1 shown in Figure 13 with Figure 14 is identical with the composition of first embodiment.Therefore, with Under explanation in, mainly to the operation panel 6 of the 4th embodiment, operation pulley 10 and winding gear mechanism (driving gear 31, Travelling gear 32, driven gear 33) illustrate.

With reference to Figure 13, the operation panel 6 of the 4th embodiment and concrete composition about are illustrated.In rolling tube 9 At right part, in the same manner as first embodiment, rolling tube 9 is supported for can be with respect to consolidating of extending from support member 2a Dead axle 11 is rotated.Operation pulley 10 is provided with through hole, using fixing axle 11 as rotary shaft.Rolling tube 9 can be with behaviour Make the rotation of pulley 10 and rotated.

The right part of operation pulley 10 is fixed with the driving gear 31 rotating with the rotation of operation pulley 10, in this drive The right-hand member of moving gear 31, is provided likewise with generally cylindrical rotation support portion 24 with first embodiment.And, operation panel 6 It is provided with diameter and be slightly larger than this rotation support portion 24 and the rotation receiving portion 23 in circular hole.Therefore, operation panel 6 is supported for： Can be rotated with respect to fixing axle 11, operation pulley 10 and rolling tube 9.

In addition, the right part of the support shaft 7 extending between support member 2a, 2b, it is provided with for making support shaft 7 rotate Driven gear 33, operation panel 6 is provided with hole portion 22, will pass through the holding member 21 of rivet etc. with can be with respect to operation panel 6 The mode being rotated supports this driven gear 33.

And, on operation panel 6, in the way of being rotated with respect to operation panel 6, travelling gear 32 is installed, should Travelling gear 32 is used for for the rotation of driving gear 31 passing to driven gear 33.Travelling gear 32 is configured to driving gear 31 rotation passes to driven gear 33.

Therefore, if rolling tube 9 is set to the first wireline reel for cord 4, support shaft 7 is as the of cord 4 Two wireline reels and play a role.In addition, the diameter with diameter greater than the second wireline reel of the first wireline reel.Driving gear 31 and driven The number of teeth of gear 33 is identical, thus the rotation number of the second wireline reel is identical with the rotation number of the first wireline reel.Therefore, the first volume around The winding of the cord 4 when the spooling length of cord 4 during axle every rotational units number of turns and the second wireline reel every rotational units number of turns Length is different.When pull operation rope 3 makes operation pulley 10 rotate towards coiling direction, the first wireline reel is rotated and is rolled up Around cord 4, and the second wireline reel also winds cord 4, so that underbeam 5 rises.During rising, on the first wireline reel The rate of climb of cord 4 of front face side and the cord 4 of the rear side on the second wireline reel the rate of climb different (first The rotary speed of wireline reel>The rotary speed of the second wireline reel), therefore, the light shielding part 4a state overlapping with transmittance section 4b and screening The 4a state overlapping with light shielding part 4a in light portion is alternately present.This situation is also identical in unwinding.It is located at lower limit in cord 4 In the state of putting place, it is changed into the light shielding part 4a state overlapping with transmittance section 4b, is accordingly changed into shading status.

The operation panel 6 of the 4th embodiment so constituting, also when operating to operating rope 3, to allow to relatively The mode that the interval of the double-deck cord 4 of movement increases carries out pendular movement.Especially, operation panel 6 is so that rolling tube 9 and support shaft Between position relationship when position relationship when static for the position relationship between 7 and operation, the mode of change carries out pendulum fortune Dynamic.And, operation panel 6 is configured to：Make double-deck cord 4 operation when interval be more than static when interval.

Hereinafter, with reference to Figure 14, the action of operation panel 6 is more specifically illustrated.First, with reference in Figure 14 A (), operation panel 6 is supported for be rotated with respect to operation pulley 10 and rolling tube 9, when underbeam 5 is respectively in lower limit Put, when centre position and upper limit position remain static, by deadweight (cord 4, underbeam 5, operation panel 6, gripper shoe 8, The weight of support axle 7) and operation panel 6 is applied towards make direction that before and after's cord 4 is adjacent to, i.e. front face side (be suitable in (a) of Figure 14 Clockwise) torque.Operating rope 3 is hung down on the basis of guide portion 12,13 of restricting.

In this example, when underbeam 5 remains static in lower position, cord 4 is arranged to not be wound onto winding State on pipe 9 and support shaft 7, thus double-deck cord 4 is in position that is close to each other or being adjacent to (the interval d1 of double-deck cord 4) When the interval of double-deck cord 4 immobilize.In addition, from the light-proofness aspect improving double-deck cord 4, preferably with lower limit The position stacked mode in the longitudinal direction that under state, cord 4 hangs down from rolling tube 9 and support shaft 7, cord 4 is upper End is arranged on rolling tube 9 and support shaft 7.

And, underbeam 5 is centrally located or upper limit position, and cord 4 is wound onto winding with coil diameter R1, R2 respectively In the state of on pipe 9 and support shaft 7, double-deck cord 4 is in the interval of the double-deck cord 4 during close to each other or position that is being adjacent to Immobilize.In addition, in the 4th embodiment, due to be provided with winding gear mechanism (driving gear 31, travelling gear 32, from Moving gear 33), therefore, by by cord 4 respectively with coil diameter R1, R2 on rolling tube 9 and support shaft 7, from underbeam 5 Lower position to upper limit position in the range of, the adhesion of double-deck cord 4 improves.

Transmittance section 4b and light shielding part 4a therefore, it is possible to make double-deck cord 4 stagger and are formed as semi-transparent light state or make The transmittance section 4b and light shielding part 4a of cord 4 are completely overlapped and be formed as shading status, enable in particular to improve shading status when screening Photosensitiveness.

Next, with reference to (b) in Figure 14, from the beginning of being located at lower position or the state in centre position from such as underbeam 5 When operating rope 3 being operated and so that underbeam 5 is increased, cord 4 is wound onto on rolling tube 9 and support shaft 7.Now, by behaviour Make rope 3 to rope guide portion 12 apply torque, thus driving operation panel 6 to make pendular movement, thus make double-deck cord 4 operation when Interval d1 when interval d2 is more than static.Therefore, in lifting operations, though in front and back cord 4 because the rate of climb is different phase To movement, also will not produce friction during double-deck cord 4 relative movement or the part stage only in lifting process produces and rubs Wipe or frictional force weakens, thus not there is a possibility that to damage cord 4.

Similarly, with reference to (c) in Figure 14, when from such as underbeam 5 is centrally located or the state of upper limit position from the beginning of When operating rope 3 being operated and so that underbeam 5 is declined, the cord 4 on rolling tube 9 and support shaft 7 declines.Now, lead to Crossing operating rope 3 and torque is applied to rope guide portion 13, thus driving operation panel 6 to make pendular movement, thus making the behaviour of double-deck cord 4 Interval d1 when interval d3 when making is more than static.Therefore, in step-down operation, even if cord 4 is because of decrease speed not in front and back Relative movement together, also will not produce friction during double-deck cord 4 relative movement or the part stage only in lifting process produces Raw friction or frictional force weaken, thus not there is a possibility that to damage cord 4.

Therefore, in descending operation, operation panel 6 is made to be rotated by the pulling force of operating rope 3, so that double-deck cord 4 with the state relative movement that is separated from each other without producing friction (or, even if producing friction, friction is also weakened), thus Not there is a possibility that to damage cord 4.In addition, when remaining static, operating rope 3 loses tension force, and operation panel 6 is in cord 4 Deng deadweight in the presence of towards making the close direction of double-deck cord 4 rotate, the interval therefore, it is possible to make double-deck cord 4 reduces, Or so that double-deck cord 4 is adjacent to each other makes the transmittance section 4b of cord 4 completely overlapped with light shielding part 4a and formed such that it is able to improve For light-proofness during shading status.

Especially in the roller shutter 1 of the 4th embodiment, due to being provided with winding gear mechanism (driving gear 31, driving cog Wheel 32, driven gear 33), therefore, by by cord 4 respectively with coil diameter R1, R2 on rolling tube 9 and support shaft 7, from The lower position of underbeam 5 to upper limit position in the range of, the adhesion of double-deck cord 4 improves.

In addition, only also allow hand over the light shielding part 4a state overlapping with transmittance section 4b of before and after's cord 4 by above-mentioned composition The overlapping state of the respective light shielding part 4a of cord 4 (or transmittance section 4b) in front and back, but, by adding following compositions, can subtract The amount of moving up and down of underbeam 5 when switching less.With regard to winding gear mechanism (driving gear 31, travelling gear 32, driven gear 33), As long as and then arranging idling device, wherein, this sky on any one or both of driving gear 31 and driven gear 33 The idle running amount of rotary device is equivalent to and is changed into double-deck from the transmittance section 4b of double-deck cord 4 shading status overlapping with light shielding part 4a Displacement till the semi-transparent light state that the transmittance section 4b and light shielding part 4a of cord 4 staggers.With regard to this idling device Details, refer to such as Japan Patent, JP 2012-77501 publication.

More than, the example enumerating particular implementation describes the present invention, but the present invention be not limited to above-mentioned Embodiment example, can carry out various modifications in the range of without departing from its technological thought.

For example, as the variation of first embodiment, gear mechanism (driving gear 31, travelling gear are wound to being provided with 32nd, driven gear 33) the example of the 4th embodiment be illustrated, but, as second embodiment or the 3rd enforcement The variation of mode, it is also possible to the technical scheme of each embodiment is combined application, is formed as being provided with this winding gear mechanism The form of structure.

And then it is also possible to be configured to：It is provided with this in the variation as this second embodiment or the 3rd embodiment During winding gear mechanism, it is provided with this idling device.

In addition, in the example of the respective embodiments described above, in the double-deck cord 4 forming one piece of cord inflection On, the example being alternatively formed the light shielding part 4a of the transmittance section 4b making some light transmission and shield lights in striated is carried out Explanation, but, as long as the cord of bilayer, even if be not one piece of cord or be in not be alternately formed with transmittance section 4b and The form of light shielding part 4a, operation panel 6 according to the present invention also has effect at following aspects, that is,：In descending operation, by behaviour Make the pulling force of rope 3 and so that operation panel 6 is rotated so that double-deck cord 4 with the state relative movement that is separated from each other without Produce friction or the part stage only in lifting process produces friction or frictional force weakens.

In addition, with regard to the outer shape of support member 2a, 2b, operation panel 6 and gripper shoe 8, rope guide portion 12,13,14 Shape etc., as long as effect and the effect of the present invention can be produced, just can be formed as variously-shaped.

In addition, in each embodiment, carrying out pendular movement for gripper shoe 8 also with the pendular movement of operation panel 6 Form be illustrated, but it is also possible to the technical scheme of each embodiment is combined application, be formed as only operation panel 6 make pendular movement, thus when making static in operation the interval increase of the close to each other or double-deck cord that is adjacent to form.Example As first embodiment and second embodiment (or the 4th embodiment or its variation) being combined and be formed For following forms, that is,：It is not provided with gripper shoe 8, and the rotation bullport of the end of support shaft 7 is arranged on support member 2b, And make this rotation bullport suitably possess rotation limitation function, thus being guided with operation with bullport by this rotation The pendular movement of plate 6 and the end of support shaft 7 that rotates, thus make quiet only by the pendular movement of operation panel 6 in operation When only near or the interval increase of double-deck cord that is adjacent to.

Alternatively, it is also possible to be configured to：The wall portion (lid) erect upwards from support shaft 7 is set, thus prevent rolling tube 9 with Light leak between the installed surface of ceiling side of installing rack 2.

On the other hand, it is formed with, in the right-hand member side of rope cover 20, the protuberance (not shown) projecting with being cylindrical in shape, operate plate portion Part 6a is provided with the external diameter with diameter greater than this protuberance and rotation receiving portion 23a in circular hole, to engage with this protuberance.And And, operation plate member 6b is provided with external diameter and rotation receiving portion 23b poroid in semicircle with diameter greater than rolling tube 9.In addition, it is solid Upper protruded leaf due to the right-hand member side of the rope cover 20 of support member 2a is provided with recess 20a, and the top of operation plate member 6a sets There is the protrusion tab 61 of substantially inverted trapezoidal shape.The protrusion tab 61 of this example has roughly equal with the left and right directions width of operating unit 60 Thickness, the bottom surface of protrusion tab 61 supported along the top surface of rope cover 20, and thus, operating unit 60 is with respect to operation pulley 10 He Relatively rotating of rolling tube 9 stabilizes.Therefore, be supported for can be with respect to operation pulley 10 and rolling tube 9 for operating unit 60 Rotated.

And, in two operation plate member 6a, 6b operation pulley 10 and rope cover 20 clamping can be contained in inner side In the state of mode forms as one, protrusion tab 61 is fastened in recess 20a in the way of rotating within the limits prescribed.Separately Outward, on the inwall of the upper protruded leaf of rope cover 20 left end side that operation plate member 6b can be contained in inner side, it is provided with and will grasp That makees unit 60 relatively rotates the end difference 20b being limited in certain angle.That is, when operating unit 60 relatively rotates, this rank Terraced portion 20b can be abutted with the edge part 26 of the upper end both sides of the rope guide portion 12 of operation plate member 6b.Therefore, by edge part 26 with the abutting of end difference 20b and relatively rotating of operating unit 60 is limited in certain angle.

On the other hand, it is fixed on the outdoor side end of the bottom surface of installing rack 2 in support member 2a, 2b outstanding at two ends Hang with the movable fin 40 of substantially fin-shaped, this movable fin 40 can be rotated around its standard shaft.

The movable fin 40 of the 7th embodiment is configured to：Length is longer than the length in the 5th embodiment, will pacify The gap shelved between 2 and rolling tube 9 is blocked, and, a part of removed inside it, thus subtracting while keeping intensity Light weight.It is configured to the movable fin 40 of above-mentioned length, the gap between installing rack 2 and rolling tube 9 can be covered further The extraneous light injected, and, by its weight saving it is thus possible to the displacement reducing movable fin 40 in pendular movement is produced Raw load.It is additionally, since fixed part 2c from the outdoor side end face being arranged at installing rack 2 for the cord 4 to hang down, therefore, when logical Cross when relatively rotating and making the side end of the protrusion tab 61 of operation plate member 6a push this movable fin 40 of operating unit 60, can Dynamic fin 40 is rotated, so that the cord 4 of outside is further towards outdoor side shifting.

Hereinafter, with reference to Figure 24, the action of operating unit 60 is more specifically illustrated.First, with reference in Figure 24 (a), operating unit 60 be supported for can with respect to operation pulley 10 (and rolling tube 9) be rotated, when underbeam 5 respectively under When extreme position, centre position and upper limit position remain static, by deadweight (weight of cord 4, underbeam 5 etc.) to behaviour Make unit 60 and apply the torque towards the direction making before and after's cord 4 be adjacent to.Thus, operating rope 3 is on the basis of guide portion 12,13 of restricting And hang down.

It is located under the resting state at lower position in underbeam 5 or underbeam 5 is centrally located or upper limit position and curtain Cloth 4 is wound onto under the resting state on rolling tube 9 with the coil diameter specifying, double-deck cord 4 is in position that is close to each other or being adjacent to The interval putting the double-deck cord 4 when (the interval d1 of double-deck cord 4) immobilizes.Therefore, it is possible to make the transmittance section of double-deck cord 4 4b and light shielding part 4a stagger and be formed as semi-transparent light state or make cord 4 transmittance section 4b and light shielding part 4a completely overlapped and Be formed as shading status, enable in particular to improve light-proofness during shading status.Especially, the consolidating of the installing rack 2 of present embodiment Determine portion 2c to be configured to：Fabric pressing plate 80 is engaging in this fixed part 2c in a detachable manner, this fabric pressing plate 80 energy Enough wind the end of cord 4 such that it is able to the length of adjustment cord 4, therefore, be easily adjusted the length of cord 4, with for example Beam 5 becomes shielding status when being located at lower position.In addition, the longer movable fin 40 of length, can cover from installation further The extraneous light that gap between frame 2 and rolling tube 9 is injected.

Next, with reference to (b) in Figure 24, from the beginning of being located at lower position or the state in centre position from such as underbeam 5 When operating rope 3 being operated and so that underbeam 5 is increased, cord 4 is wound onto on rolling tube 9.Now, operating rope 3 and indoor Rope guide portion 12 abut and operating unit 60 applied with clockwise torque, thus drive operating unit 60 make pendulum fortune Dynamic, thus, the side end of the protrusion tab 61 of operation plate member 6a makes movable fin 40 be rotated, thus pushing the curtain of outside Cloth 4.Therefore, the interval d1 when interval d2 during operation of double-deck cord 4 is more than static.Therefore, in lifting operations, Double-layer curtain Cloth 4 relative movement subtracts without producing friction or the generation friction of the part stage only in lifting process or frictional force Weak, thus not there is a possibility that to damage cord 4.In addition, the rope guide portion 12 of front side and rope guide portion 13 between and rear side Rope guide portion 12 and rope guide portion 13 between, the path of navigation more slightly larger than the profile of the bulb 3a of operating rope 3 be formed： All the time abutted with any one in rope guide portion 12,13 with least two bulb 3a that prescribed distance is connected, therefore, it is possible to press down Rock in operating unit 60 during operating rope 3 operation processed, and can reduce because between bulb 3a and rope guide portion 12,13 The operation sound disturbing and producing.

Similarly, with reference to (c) in Figure 24, when from such as underbeam 5 is centrally located or the state of upper limit position from the beginning of When operating rope 3 being operated and so that underbeam 5 is declined, the cord 4 on rolling tube 9 declines.Now, operating rope 3 and room The rope guide portion 13 of inner side abuts and operating unit 60 is applied with clockwise torque, thus driving operating unit 60 to make clock Pendular motion, thus, the side end of the protrusion tab 61 of operation plate member 6a makes movable fin 40 be rotated, thus pushing outside Cord 4.Therefore, the interval d1 when interval d3 during operation of double-deck cord 4 is more than static.Therefore, in step-down operation, double Layer cord 4 relative movement produces friction or frictional force without producing friction or the part stage only in lifting process Weaken, thus not there is a possibility that to damage cord 4.Even if in addition, the fabric in cord 4 winds rugosity close to the upper limit current political situation Portion produces friction, and its frictional force is also in the trend weakening.

Therefore, in the roller shutter 1 of the 7th embodiment, in descending operation, operation list is made by the pulling force of operating rope 3 Unit 60 is rotated so that double-deck cord 4 with the state relative movement that is separated from each other without produce friction (or, even if Produce friction, friction is also weakened), thus not there is a possibility that to damage cord 4 (or probability reduction).In addition, at place When resting state, operating rope 3 loses tension force, and operating unit 60 leans on towards double-deck cord 4 in the presence of the deadweight of cord 4 grade Near direction rotates, the interval therefore, it is possible to make double-deck cord 4 reduce or so that double-deck cord 4 is adjacent to each other such that it is able to Raising makes the transmittance section 4b and light shielding part 4a of cord 4 completely overlapped and is formed as light-proofness during shading status.

In addition, in the roller shutter 1 of the 7th embodiment, the fixed part 2c of installing rack 2 is configured to：It is possible to by winding And the fabric pressing plate 80 adjusting the length of cord 4 is engaging in this fixed part 2c in a detachable manner, therefore, it is easily adjusted The length of cord 4, to become shielding status when such as underbeam 5 is located at lower position.

In addition, in the roller shutter 1 of the 7th embodiment, movable fin 40 is configured to block installing rack 2 and winding enough The length in the gap between pipe 9, therefore, it is possible to cover the outside that the gap between installing rack 2 and rolling tube 9 is injected further Light.

In addition, in the roller shutter 1 of the 7th embodiment, between rope guide portion 12 in front side and rope guide portion 13 and Rear side rope guide portion 12 and rope guide portion 13 between, with prescribed distance be connected at least two bulb 3a all the time with rope guide portion 12nd, any one in 13 abuts and is directed, therefore, it is possible to suppress to rock in operating unit 60 during operating rope 3 operation, and And the operation sound producing because of the interference between bulb 3a and rope guide portion 12,13 can be reduced.

More than, the example enumerating particular implementation describes the present invention, but the present invention be not limited to above-mentioned The example of embodiment, can carry out various modifications in the range of without departing from its technological thought.For example, in each embodiment In, it is illustrated with the state determining indoor and outside, but it is also possible to oppositely arranged indoor and outside.

In addition, in order to reliably make cord 4 separate in operation it is also possible to setting auxiliary separates towards cord 4 further The force application part such as the spring of the pendular movement of direction movement.

(industrial utilizability)

According to roller shutter 1 according to the present invention, in descending operation, the relative movement of double-deck cord 4 without produce friction or Person only produces friction in the part stage of lifting process or frictional force weakens, and therefore, not there is a possibility that to damage cord 4, And when remaining static, the interval of double-deck cord 4 can be made to reduce or so that double-deck cord 4 is adjacent to each other, especially exist When cord 4 has transmittance section 4b and light shielding part 4a, it is possible to increase make transmittance section 4b and light shielding part 4a completely overlapped and be formed as hiding Light-proofness during light state, therefore, it is possible to effectively be used in the purposes of the shutter of the double-deck cord of use etc..
