Shown in Fig. 2-5 and 7-9, the elevating mechanism 6 that is arranged in the back of said a plurality of lath 4 at fore-and-aft direction Y comprises the moving device 103 that the coupling mechanism 102 and being used to that termination chain 101 is arranged, be connected in an end 98 of chain 101 attachment pegs 61 of lower strip 4b as flexible thin and long units makes chain 101 advance along A and B direction.
Moving device 103 comprises: as the sprocket wheel 104 of rotor, chain 101 is around being meshed above that and with it, and sprocket wheel 104 can be to r1 and the rotation of r2 direction; The cross section is hexagonal rotating shaft 105, and sprocket wheel 104 is anchored on this rotating shaft, and this rotating shaft extends horizontal direction X and supported and can rotated to r1 and r2 direction by inside casing 16; And the motor 106 that has reducer, its be connected in rotating shaft 105 and when being started as the power source that rotating shaft 105 is rotated.When motor 106 was started, moving device 103 just made rotating shaft 105 rotate to r1 or r2 direction, and this rotation makes sprocket wheel 104 rotate to r1 or r2 direction again, so chain 101 is advanced along A or B direction.
In order to guide chain 101 the advancing of vertical direction Z, chain 101 is sandwiched in and inside casing 16 is configured as one and extends vertical direction Z each between guide protrusion 111 and 112, so as to preventing the deflection of chain.
At fore-and-aft direction Y, sprocket wheel 104 is the back that are arranged in said a plurality of lath 4 with rotating shaft 105, and at vertical direction Z, and they are arranged in below top bars 4a and the lath supporting member 141.
Equally; On vertical frame 12; Elevating mechanism 6 comprises chain, sprocket wheel and coupling mechanism; They are respectively being shaped with chain 101, sprocket wheel 104 and the coupling mechanism 102 identical modes of vertical frame 11 those sides, and all are configured to drive at motor 106 and raise on the basis that rotating shafts 105 rotate and reduce lath 4b.Rotating shaft 105 extends to vertical frame 12 at horizontal direction X from vertical frame 11, and also is anchored on sprocket wheel in vertical frame 12 those sides, and this sprocket wheel is identical on forming mode with sprocket wheel 104.
Because above-mentioned elevating mechanism 6 is arranged, to start motor 106 and just can drive rotating shaft 105 and sprocket wheel 104 is rotated to the r1 direction, this rotation makes chain 101 advance along the A direction, and this is advanced and through coupling mechanism 102 lower strip 4b is reduced.Like this, said a plurality of lath 4 begins to be reduced together from lower strip 4b.On the other hand, start motor 106 and just can drive rotating shaft 105 and sprocket wheel 104 is rotated to the r2 direction, this rotation makes chain 101 advance along the B direction, and this is advanced and through coupling mechanism 102 lower strip 4b is raise.Like this, said a plurality of lath 4 begins to be raise together from lower strip 4b.
Like Fig. 2-5,7, shown in 8 and 10, gradient modifier 7 comprises: lath supporting device 131, and it is used for rotationally and supports top bars 4a movably at fore-and-aft direction Y; And motion 132; It is connected in that part (the back edge part 35 of lath 4a) of that part (barycentric subdivision 39 of lath 4a) that is being supported by lath supporting device 131 back that is positioned at it of lath 4a rotationally; Motion 132 be configured to can elevating mechanism 6 lath 4 is raise and the basis that reduces on the back edge part 35 of lath 4a is moved at vertical direction Z, thereby cause back edge part 35 to change the gradient of lath 4a with respect to the relative displacement of the barycentric subdivision 39 of the lath 4a that is supporting by lath supporting device 131 at vertical direction Z.
Like Fig. 4,5, shown in 7 and 10, lath supporting device 131 comprises: lath supporting member 141, and it is used for rotationally and supports top bars 4a movably at fore-and-aft direction Y; And linkage, it is used for being connected in vertical frame 11 to lath supporting member 141, and in this embodiment, linkage is the linkage 142 that is used in the predetermined stroke of vertical direction Z, being connected in lath supporting member 141 movably inside casing 16.
Coupling part 148 is arranged in the extension that as above-mentioned, stretches out 146 of plate-like body 147.Coupling part 148 among this embodiment has the elongated orifices 149 that extends fore-and-aft direction Y, and bolster 51 passes this hole.The bolster that passes elongated orifices 149 51 of lath 4a can move at fore-and-aft direction Y along elongated orifices 149; Thereby be accompanied by the rectilinear motion of the back edge part 35 of lath 4a at vertical direction Z; Bolster 51 is allowed to respect to the motion of lath supporting member 141 at fore-and-aft direction Y, and it be under an embargo because of the plate-like body 147 that it is resisted against elongated orifices 149 places with respect to the motion of lath supporting member 141 at vertical direction Z.In addition, bolster 51 is to be in rotationally in the elongated orifices 149.

Like the detailed expression of Figure 14 and 15, slide mechanism 199 comprises: hollow substantially cylindrical rotor 211, and it is anchored on rotating shaft 105 and can rotates with rotating shaft 105; Helical spring 212, its on the external peripheral surface of rotor 211 and with rotor 211 CONTACT WITH FRICTION; Retaining part 215 with C shape cross section, its diameter is greater than the diameter of rotor 211 and be arranged to cover rotor 211 and helical spring 212, and maintains an end 213 and the other end 214 of helical spring 212; And hollow plate-like fastening part 218, it is used for being tightened to one to the side 216 of retaining part 215 and the side 217 of pinion 204.
Rectilinear motion prevents mechanism 200 to comprise: the pin 219 that is anchored on rectilinear motion spare 161; Latch members 221, its lockable lifting that can prevent rectilinear motion spare 161 in pin 219 releasedly, and it is fixed in the fixed head part 193 of fixed component 184 rotationally through bearing pin 220; Torsion coil spring 222 is as the member that forces that forces latch members 221, in order to keep latch members 221 lockings in the state of pin 219; And the projection shown in Figure 18 and 19 223; Its other end that is connected in chain 101 also can make latch members 221 opposing the forcing power of torsion coil spring 222 against latch members 221 and rotate, thereby discharges latch members 221 lockings in the state of pin 219.One end of torsion coil spring 222 is being suppressed by latch members 221, and its other end is pinned by fixed component 184, and spring itself is on bearing pin 220.
Shown in figure 18; Because the projection 223 that is promoted along advancing of A direction by chain 101 is against stop surfaces 233; Latch members 221 is rotated around bearing pin 220 to the pushing of D direction, thereby makes lock claw portion 232 break away from pin 219, and then discharges the prevention effect to the lifting of rectilinear motion spare 161.
In the opening open mode of blind device 1, opening 3 opens wide, and is as shown in Figure 3; At this state; Said a plurality of lath 4 builds up bundle mutually on the top of opening 3, constitutes lead edge portion that leading edge links row and links part 73 and 74 and be piled up and be positioned at recess 32, and is as shown in Figure 6; Constitute back edge that back edge links row and partly link part 83 and 84 and be overlapped at fore-and-aft direction Y and give prominence to the back of said a plurality of laths 4, and between housing 15 and inside casing 16, as shown in Figure 6; Lath supporting member 141 is positioned at and is in the state that lath supporting member 141 is raised up by that lath 4 below the top bars 4a away from the position of stop surfaces 153, and is as shown in Figure 4; And rectilinear motion spare 161, lath 4 raises up below the top bars 4a owing to adjoined at vertical direction Z, and is in the lateral ends of horizontal upper side frame 13.Should be able to notice; Lath supporting member 141 possibly be raised because of that lath 4 below top bars 4a, or maybe since lath 4a with its lead edge portion 33 against the lead edge portion 33 of following that lath 4 and since rectilinear motion spare 161 against the back edge part 35 of following that lath 4 and that lath 4 below the top bars 4a of quilt raises up.In addition, with lath supporting member 141 parallel because of that lath 4 below lath 4a is raised simultaneously be that lath supporting member 141 possibly raised up through lath 4a and rectilinear motion spare 161 by that following lath 4.
Opening at blind device 1 is closed state, and opening 3 is closed, and is shown in figure 19, and at this state, the leading edge 28 of top bars 4a is against the back edge part 35 of that lath 4 that is adjacent to lath 4a; The back edge part 35 of lower strip 4b is adjacent to the leading edge 28 of that lath that is adjacent to lath 4b 4; The leading edge 28 of those the many laths 4 between lath 4a and the lath 4b is respectively against the back edge part 35 of each lath 4 that is adjacent to them, and simultaneously, the back edge part 35 of those many laths 4 is respectively against the leading edge 28 of each lath 4 that is adjacent to them; Constitute lead edge portion that leading edge links row link part 73 with 74 and the formation back edge back edge that links row partly link part 83 and 84 and trailed respectively; Lath supporting member 141 is in the position that is resisted against stop surfaces 153 after said a plurality of lath 4 has been lowered with the load that links mechanism 5 because of bearing; And rectilinear motion spare 161 is in the extreme higher position in each position of vertical direction Z at its moving linearly place.
Below, will specify the operation of closing opening 3 with the blind device 1 of this embodiment with reference to each accompanying drawing.
At first, be in the opening open mode from blind device shown in Figure 31 and begin operation, start motor 106 rotating shaft 105 is rotated to the r1 direction, thereby chain 101 is advanced along the A direction through sprocket wheel 104.Because chain 101 advances along the A direction, be connected in through coupling mechanism 102 chain 101 an end 98 lower strip 4b and through linking said a plurality of laths 4 that mechanism 5 is connected in lath 4b by to decline.When descending with said a plurality of laths 4, lath supporting member 141 also descends, is resisted against stop surfaces 153 and decline is restricted up to lath supporting member 141.Though rotating shaft 105 puts on helical spring 212 to the rotatory force of the turning handle r1 of r1 direction direction; But because latch members 221 is to pin in pin 219; As shown in Figure 3, helical spring 212 only produces with respect to the slip of rotor 211 and does not rotate to the r1 direction.Therefore, rectilinear motion spare 161 is in and a kind ofly has upwards rectilinear motion power to act on it through transmission mechanism 163 but it does not produce straight-line state upwards, thereby the back edge part 35 of lath 4a is not moved at vertical direction Z yet.Since lath supporting member 141 by with said a plurality of lath 4 to decline, as stated, the barycentric subdivision 39 of lath 4a is also moved at fore-and-aft direction Y to descending simultaneously backward.This decline can make the relative displacement that is created in vertical direction Z between the back edge part 35 of barycentric subdivision 39 and lath 4a, and that lath 4a is tilted to the R1 direction as a result.The inclination of the lath 4a that is caused by the decline of lath supporting member 141 will be stopped against stop surfaces 153 because of lath supporting member 141.
Along with at a plurality of laths 4 below the top bars 4a by further to decline; That a pair of lead edge portion of going up that is connected in by the top bars 4a of lath supporting member 141 supporting links part 73 and 74 and go up that a pair of back edge partly links part 83 and 84 quilts are trailed most, and the decline of lath supporting member 141 can only drop to the precalculated position because of the restriction that receives it and be resisted against that lath 4 below stop surfaces 153 and the lath 4a.Link in above-mentioned lead edge portion part 73 and 74 and back edge partly link below part 83 and 84 each to the lead edge portion link part 73 and 74 and each back edge partly linked part 83 and 84 also all one after the other trailed.As a result, the lapping of said a plurality of laths 4, lath 4 beginnings above each, by cancellation in succession, shown in figure 17.
Shown in figure 18, when all each to the lead edge portion link part 73 and 74 and each when back edge is partly linked part 83 and 84 and is all trailed, the projection 223 that is promoted along advancing of A direction by chain 101 is against the stop surfaces 233 of latch members 221.When the projection 223 against stop surfaces 233 is promoted along advancing of A direction is further by chain 101; Stop surfaces 233 rotates latch members 221 to the pushing of D direction; This rotation can discharge latch members 221 pins in the state of pin 219, shown in figure 18.Like this, the straight-line prevention of making progress of rectilinear motion spare 161 just has been released.Be delivered under the situation of rectilinear motion spare 161 through slide mechanism 199 and rack-and-pinion mechanism 201 in the rotation of rotating shaft 105 to the r1 direction, the rectilinear motion spare 161 that straight-line prevention has been discharged in this wise moves upward at vertical direction Z under the effect of the rectilinear motion power that makes progress point-blank.This rectilinear motion makes rectilinear motion spare 161 produce the relative displacement with respect to lath supporting member 141 at vertical direction Z; This displacement make rectilinear motion spare 161 be in further lath supporting member 141 above, and then lath 4a is also further tilted to the R1 direction.
All each the lead edge portion is linked part 73 and 74 and each back edge is partly linked in the situation that part 83 and 84 all trailed; As stated; If chain 101 is further advanced along the A direction; The connector 116 of coupling mechanism 102 will further be reduced with respect to lower strip 4b, and the rotation that link arm 120 is produced to the F direction, this rotation can make lath 4b move backward in the Y of front and back direction.Should be able to notice; On the basis that has discharged the rectilinear motion prevention that applies by rectilinear motion prevention mechanism 200; The upwards rectilinear motion of rectilinear motion spare 161 and the rotation to the F direction of link arm 120; In this embodiment, be designed to synchronously to begin (particularly chain 101 from an end 98 on the Design of length of the other end that is provided with projection 223 99).
When coupling mechanism 102 was lowered and be positioned at its extreme lower position, shown in figure 19, chain 101 was stopped along advancing of A direction, and advance this stop finishing link arm 120 at the rotation of F direction and the rectilinear motion that makes progress of rectilinear motion spare 161.So the opening that blind device 1 just is set in the above described manner shown in Figure 19 and 22 is closed state.
Below, will specify the operation of opening opening 3 with reference to each accompanying drawing with the blind device 1 of this embodiment.
At first, be in opening shown in Figure 19 at blind device 1 and be closed state, start motor 106 rotating shaft 105 is rotated to the r2 direction, thereby chain 101 is advanced along the B direction through sprocket wheel 104.Because chain 101 advances along the B direction, the lower strip 4b that is connected in an end 98 of chain 101 through coupling mechanism 102 is raised, and is shown in figure 20.Rotating shaft 105 is delivered to rectilinear motion spare 161 through slide mechanism 199 and rack-and-pinion mechanism 201 as downward rectilinear motion power to the rotation of R2 direction.Rectilinear motion spare 161 moves downward and produces the relative displacement with respect to lath supporting member 141 point-blank under the effect of this rectilinear motion power that is delivered to it.So top bars 4a is tilted the direction in R2, and is shown in figure 20, and the said a plurality of laths 4 below lath 4a,, also all favour the R2 direction in an identical manner because the tilting force of lath 4a is delivered to them through linking mechanism 5.Said a plurality of laths 4 all with chain 101 when advancing of B direction favours the R2 direction explicitly, link arm 120 is also rotated to the G direction in contrast to the F direction, thereby said a plurality of lath 4 is travelled forward at fore-and-aft direction Y.When link arm 120 by when the G direction is rotated scheduled volume, this rotates is placed restrictions on piece 121 and is resisted against connector 116 and places restrictions on, so the link arm 120 of being placed restrictions on like this is set in horizontal state substantially.
That a pair of lead edge portion down that is connected in lower strip 4b and that lath 4 above the lath 4b link part 73 with 74 and time that a pair of back edge partly link part 83 and 84; Shown in figure 19; All along with lath 4b is raised and is piled up; So, by that a pair of lead edge portion that has been piled up link part 73 with 74 and that a pair of back edge partly link lath 4b that part 83 is connected with 84 and those lath 4 mutual lappings above the lath 4b.The most a pair of lead edge portion link part 73 with 74 and the most a pair of rear edge portion branch link many more than part 83 and 84 lead edge portion linked part 73 and 74 and manyly back edge is partly linked part 83 and 84 also all one after the other be piled up.So the lath 4 of said a plurality of laths 4 below each begins lapping one after the other, and be shown in figure 20.
The rectilinear motion spare that moves down point-blank 161 is even its lock claw portion that is positioned at latch members 221 still moves down below 232 point-blank.When said a plurality of laths 4 were set in heeling condition shown in figure 20, rolling element 185 was against fixed component 184, thereby the prevention rectilinear motion moves downward that below position.
Chain 101 can promote lath 4b along advancing of B direction;; Since this lifting such a plurality of laths 4 that tilt shown in figure 20 by one after the other mutual lapping as above-mentioned and when being set in state shown in Figure 21; Rectilinear motion spare 161 is upwards lifted point-blank because of the back edge part 35 of the lath 4 below the extension 175 of rectilinear motion spare 161 and by it and is moved upward; And on the rectilinear motion basis of rectilinear motion spare 161, top bars 4a is tilted the direction in R1, and with the lead edge portion 33 of its lead edge portion 33 against following that lath 4.In the upwards rectilinear motion of that rectilinear motion spare 161; The rotational load that scheduled volume being equal to or higher than appearred in slide mechanism 199; So that the slip that slide mechanism 199 produces with respect to 105 is released so the rotation of rotating shaft 105 can be delivered to the sort of state of rectilinear motion spare 161.Lath supporting member 141 raises because of that lath 4 below lath 4a lifts.So blind device 1 just is set in opening open position shown in Figure 3 in the above described manner.Should be able to notice; Lath supporting member 141 possibly be lifted because of that lath 4 below top bars 4a; Perhaps; Because lath 4a is with the lead edge portion 33 of the lath 4 of its lead edge portion 33 below that and because the back edge part 35 of the lath 4 of rectilinear motion spare 161 below that, lath supporting member 141 possibly lifted by that lath 4 below the top bars 4a.In addition, with lath supporting member 141 parallel simultaneously because of that lath 4 below top bars 4a is lifted be that lath supporting member 141 possibly lifted through lath 4a and rectilinear motion spare 161 by the lath below that 4.
In blind device 1 of the present invention; Be similar to the structural configuration of those structural configuration that link mechanism 5, elevating mechanism 6, gradient modifier 7 or the like; But do not comprise the structural configuration of rotating shaft 105 and motor 106, can also be arranged on vertical frame 12 those sides.Can rotating shaft 105 be extended to vertical frame 12 those sides always, with gradient modifier 7 rotatory force is provided for the elevating mechanism 6 that is located at vertical frame 12 those sides.Like this, can the elevating mechanism 6 in vertical frame 12 those sides be configured to and can synchronously work with gradient modifier 7 with the elevating mechanism 6 in vertical frame 11 these sides with gradient modifier 7.
