With in the blinds apparatus 1, under the state that opening P opens, projection 101 is arranged in the guiding channel 19 at above-mentioned window, belt body 21 and 25 keeps deflection, as shown in figure 12, and all laths 9 overlap the top (piling up) of another piece lath one of lower position, as shown in figure 11.In sealing opening P, when ball chain 71 with manual mode along a direction advance so that chain 52 when direction A advances, the lath supporting member 8 of the top at first begins to raise.When the lath supporting member 8 of the top raise thus, coupling mechanism 4 and 5 shoestring 21 and 25 launched fully, and the lath supporting member 8 that allows lath supporting member 8 to follow the top begins to raise.Then, lath supporting member 8 raises thereupon in a similar manner successively, and all laths 9 also raise simultaneously successively.When projection 101 is directed passage 19 guiding and when raising, the state that all laths 9 keep approximate horizontal to tilt, consequently opening P is had all lath sealings of rattan (rattan) shutter mode, as illustrated in fig. 1 and 2.
When chain 52 further when direction A advances, launch fully the position of shoestring 21 and 25 before the complete closure of opening P.Meanwhile, the lath supporting member 8 of below is offset the elasticity of helical springs 124 by shoestring 21 and 25 and is raise slightly.Yet when projection 101 during in the face of guide recess 102 and in abutting connection with cam member 103, lath supporting member 8 beginnings of the top are along the rotation of R1 direction, and the ascensional range of the upper end 32 of shoestring 25 is greater than the upper end 28 of shoestring 21.Therefore, the lath 9 of the top rotates along the R1 direction, the rotation of the lath supporting member 8 of the top is delivered to the lath supporting member 8 of below by shoestring 21 and shoestring 25, by this all lath supporting members 8 and lath 9 is remained under the state that approximate vertical tilts, shown in Figure 13 and 14.Thus, opening P is by all lath 9 complete closed.
When opening P opens, ball chain 71 moves with above-mentioned side in the opposite direction with the manual mode edge, and projection 101 is directed to guiding channel 19 from guide recess 102, when the lath supporting member 8 of the top reduces, begins to make shoestring 21 and 25 deflection successively from its lower position.
Adopt the above-mentioned window blinds apparatus 1 that is provided with paired lath supporting device 50, each lath supporting device has coupling mechanism 4,5 and lath supporting member 8, coupling mechanism 4 and 5 is made of flexible shoestring 21,25 and the shaft component 23,26 that is fixed with shoestring 21,25 respectively, and be rotatably connected to the end 6,7 of lath supporting member 8, the chain that replaces a pair of rigid connection part that connects in the chain mode is so that it can be by all rotation.Therefore, can assemble coupling mechanism 4 and 5 at short notice.In addition, the weight of coupling mechanism 4 and 5 can be done gently,, be made it be easy to realize the rising and the decline of all laths 9 by this so that the required power of all lath of lifting 9 is little.
In addition, according to lath supporting member 8, arm 31 has paired through hole 30 in one end and the other end, wherein rotatably inserts and be fixed with the axial region 47 at end place of the shaft component 23,26 of coupling mechanism 4,5 respectively.In addition, arm 35 has paired through hole 34 in one end and the other end, wherein rotatably inserts and be fixed with the axial region 47 at the other end place of the shaft component 23,26 of coupling mechanism 4,5 respectively.In addition, provide such setting: arm 31 and 35 is connected to each other by installation and fastening devices 40, so that an end of arm 31 and 35 and the corresponding through hole 30 and 34 in the other end become coaxial setting.Then, bindiny mechanism 4 and 5 shaft component 23 and 26 are rotatably supported in both sides, and can guarantee the smooth rotation of shaft component 23 and 26.Therefore, promptly use flexible shoestring 21 and 25 to replace the rigid connection part, shoestring 21 and 25 also can launch and deflection easily, makes its steady rising and reduction that can realize all laths 8, and suitably supports all laths 9.
In the above-described embodiments, can use loop chain to replace having the chain 52 of end 53 and 54.In this case, as long as it is just enough that another sprocket is set except that sprocket 84, loop chain is reeled and between two sprocket.If use this loop chain, can omit the disease-prevention institutions 57.In addition, can use synchronous band to wait and replace chain 52.Using under the situation about being with synchronously, as long as use a toothed pulley to replace sprocket 84 just enough.
In addition, as mentioned above, installation and fastening devices 40 are configured to make the hollow, rectangular tube 43 with construction opening 41 to be integrally formed on another surface of arm 31, and paired engagement protrusion 44 is integrally formed on the surface of arm 35.For replacing this set, can be arranged to make hollow, rectangular tube 43 to be integrally formed on the surface of arm 35 installation and fastening devices 40, and be used for tube 43 is engaged in another surface that the paired engagement protrusion 44 that cooperates opening 41 is integrally formed in arm 31 with construction opening 41.
