Described two sliding seat 30 and each affiliated described first coiler, second coiler 20, 201, jointly unroll for central sill rope 50 and underbeam rope 55 respectively, so that described sliding seat 30 slidably in upper beam 10 on the way, form central sill rope 50 launch to furl with underbeam rope 55 and transfer action, described sliding seat 30 periphery establishes the pulley 31 of several contact upper beam 10 inwalls, towards the first coiler, second coiler 20, described in 201, end is pivoted with and somely wears around post 32, with make two sliding seat 30 respectively with the first coiler, second coiler 20, between 201, supply central sill rope 50 respectively, underbeam rope 55 is worn around therebetween, a spigot 33 is installed in sliding seat 30,
Described spring 40 has two ends, first respectively, two ends 4142, first end 41 hook is due to described solid seat 45, Gu seat 45 is in response to the first coiler, second coiler 20, 201 and have two, be individually fixed in the inside wall 1112 of upper beam 10, and two solid seat 45 and the first coilers, second coiler 20, 201 is corresponding point of two ends occuping upper beam 10, the second end 42 hook for spring 40 schedules each first coiler, second coiler 20, the spigot 33 of sliding seat 30 corresponding to 201, sliding seat 30 is allowed to borrow the elasticity of spring 40 to provide displacement capacity, and curtain body 17 is launched or folded, all be installed on upper beam 10 so as to the first coiler, the solid seat 45 of the second coiler 20,201 and two groups of sliding seat 30, two springs 40, two.
So during assembling, as shown in Fig. 2 A, Fig. 2 B, for connecting described upper, middle and lower beam 101518 and curtain body 17, first coiler 20 and sliding seat 30 thereof are worn around two central sill ropes 50, make described two central sill ropes 50, respectively from the through wires hole 1112 of upper beam 10, down pass to be connected to central sill 15, and the second coiler 201 and sliding seat 30 thereof are worn around two underbeam ropes 55, make described two underbeam ropes 55, respectively from the through wires hole 1112 of upper beam 10, down pass central sill 15, curtain body 17 and be connected to underbeam 18, allow central sill rope 50, underbeam rope 55 control central sill 15 and underbeam 18 respectively.
Please referring again to shown in Fig. 4 A and Fig. 4 B, when curtain body 17 does not launch, user is with hand push-and-pull central sill 15, the strength of underbeam 18, change the first coiler, second coiler 20, central sill rope 50 in sliding seat 30 corresponding to 201, the degree of tightness state of underbeam rope 55, and then cooperation pulls spring 40 to slide to touch the first coiler separately, second coiler 20, 201, by all central sill ropes 50 of upper beam 10, underbeam rope 55 is transferred to limit travel, and make central sill 15 drive curtain body 17 to fold towards underbeam 18, hollow is abdicated between central sill 15 and upper beam 10, the viewing area 70 seen outside room can be known.
And Fig. 5 A, Fig. 5 B explanation, do not leave between upper beam 10 at central sill 15, before curtain body 17 does not launch, the hand-holdable tieing 52 of user is to pull out central sill rope 50 1 sections of suitable lengths, in the lateral surface of grooving 231, at central sill rope 50, a dynamic resistance part 60 is set, described dynamic resistance part 60 external diameter is greater than grooving 231 and avoids central sill rope 50 to be retracted by spring 40 again, central sill rope 50 is provided to be around the first coiler 20, the length of sliding seat 30 has adjustment reduction effect, described dynamic resistance part 60 is located at central sill rope 50 and pulls out optional position outside the first coiler 20, change between the first coiler 20 and the sliding seat corresponding to it 30, its central sill rope 50 line length received.
Please continue again to coordinate Fig. 6 A and Fig. 6 B, even if central sill rope 50 as shown in Figure 5 B, arrange dynamic resistance part 60 to change and reduce the line length that the first coiler 20 stayed by central sill rope 50, but underbeam rope 55 can not be had influence on, therefore when push-and-pull underbeam 18, pull underbeam rope 55 and make sliding seat 30 corresponding to the second coiler 201, coordinate extension spring 40, along upper beam 10 displacement, therefore underbeam rope 55 is driven to transfer rope length to reduce underbeam 18, and then the adjustment position that the relative position launching curtain body 17, first coiler 20 and sliding seat 30 thereof is still identical with Fig. 5 A, B.
Secondly, Fig. 7 A, Fig. 7 B is then at Fig. 5 A, under the base state of Fig. 5 B, push-and-pull central sill 15 is to leave underbeam 18, central sill rope 50 is driven to transfer rope length from sliding seat 30, sliding seat 30 is along upper beam 10 displacement, until sliding seat 30 touches the first coiler 20, the viewing area 75 now formed between upper beam 10 and central sill 15 is as seen little compared with the viewing area 70 of Fig. 4 B, this namely dynamic resistance part 60 reduce central sill rope 50 to stay the rope of the first coiler 20 long, so change the spatial dimension between upper beam 10 and central sill 15, reach the function of adjustment viewing area 70 range size, now underbeam 18 and curtain body 17 thereof not yet launch, second coiler 201 and corresponding sliding seat 30 position thereof, different from the first coiler 20.
Under Fig. 8 A, Fig. 8 B are then presented at the base state of Fig. 5 A, B, push-and-pull underbeam 18 is to drive underbeam rope 55, priming sliding seat 30 is towards the second coiler 201 displacement, therefore all underbeam ropes 55 are transferred, underbeam 18 is allowed to move down and to expand curtain body 17, even if curtain body 17 launches completely, do not hinder the range size of original adjusted viewing area 75 between upper beam 10 and central sill 15 yet.
Above-described embodiment is only for clearly illustrating that the utility model creates example, and not the utility model is created to the restriction of detailed description of the invention.In order to the syntagmatic of each parts is clearly described, carry out usually describing around its function to various illustrative parts and annexation thereof above, combination as this parts realizes which kind of function, the design constraint depending on specific application and apply whole device.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.All in spirit of the present utility model and principle any apparent change of extending out or variation be still in the protection domain of this claim.
