Detailed description of the invention
First, first refer to Fig. 1, 2, shown in 3, a kind of structure of curtain, it comprises: two fixed supports 10, one curtain sheet unit 20 and a driver element 30, wherein, two fixed supports 10 are equipped with a non-circular open-work 11, the axostylus axostyle 12 of a non-cylindrical is provided to run through location, this axostylus axostyle 12 1 end forms a baffle plate 121, and outside the open-work 11 being limited to fixed support 10, and this axostylus axostyle 12 at least wears a connect apertures 122, one curtain sheet unit 20 has a curtain body 21 and reels by a scroll bar 22 to be concentrated, and be provided with a counterweight 23 in curtain body 21 end, and these scroll bar 22 both sides limit respectively and are provided with a connection piece 24, its scroll bar 22 internal diameter two side ends is provided with spacing salient point 221, and be provided with some fins 241 with spacing salient point 221 against restriction in connector 24 with radial, this connector 24 is axially arranged with pass through aperture 242, coordinate wear be limited to two fixed supports 10 axostylus axostyle 12 on, the moving part 31 cooperation group that one driver element 30 has a non-cylindrical enters in the scroll bar 22 of curtain sheet unit 20, wherein scroll bar 22 is that cooperation group establishes curtain body 21 another relatively toward internal diameter recessed formation one fin 222, the moving part 31 of non-cylindrical is provided to insert spacing, this moving part 31 is at least axially equipped with two perforation 311, an elastic threads 32 is provided to wear back and forth, and elastic threads 32 is sequentially passed through the connect apertures 122 of two shaft lever 12 around link, so that moving part 31 is limited between two shaft lever 12 by elastic threads 32, and reverse moving part 31 in curtain body 21 in advance make elastic threads 32 compress tool retracting strength by intervolving in state of scroll bar 22.
The composition of its structure, refer to Fig. 1 again, 2, 3, shown in 4, this driver element 30 coordinates to insert in the scroll bar 22 of curtain sheet unit 20, combination is worn with the axostylus axostyle 12 of fixed support 10 again by the connector 24 of scroll bar 22 both sides, wherein, moving part 31 is to provide an elastic threads 32 and is arranged in two perforation 311 back and forth, and elastic threads 32 is worn around linking by connector 24 and the connect apertures 122 of fixed support 10 upper shaft lever 12 simultaneously, again the two ends fag end stitch of elastic threads 32 is fixed, by elastic threads 32, moving part 31 is limited in scroll bar 22 and between two shaft lever 12 thus, and utilize elastic threads 32 elastic pulling force to be drawn toward scroll bar 22 end by two fixed supports 10 to lean on, axostylus axostyle 12 is made relatively to be arranged in the through hole 242 of connector 24, with the axis client utilizing axostylus axostyle 12 to form the rotation of scroll bar 22 winding, and the moving part 31 of this driver element 30 rotates by scroll bar 22 interlock in advance, make elastic threads 32 by twist compression tool retracting strength, and the curtain body 21 of curtain sheet unit 20 is formed rolled condition simultaneously, pass through said structure, to complete a kind of structure of curtain.
The state of the actual use of its structure, continuous refer to Fig. 1 and coordinate Fig. 4, shown in 5, its curtain does not use and curtain body 21 furls completely by scroll bar 22 time, because the elastic threads 32 of this driver element 30 has been reversed in advance and had a retracting strength, the formation positioning states and the retracting strength that the counterweight 23 that curtain sheet 21 end group is established has a gravity and an elastic threads 32 is contended with, when curtain body 21 pulled down is launched by reality use, namely its scroll bar 22 can launch along with curtain body 21 and rotate, and the moving part 31 of interlock driver element 30, make moving part 31 synchronous rotary and elasticity of torsion rope 32, elastic threads 32 is allowed more to tighten and to increase retracting strength, when now relieving counterweight 23 stops curtain body 21 to continue to launch, its counterweight 23 continues to contend with elastic threads 32 because sinking to increasing gravity, curtain body 21 can not only be avoided to continue drop-down expansion, its scroll bar 22 also can not be subject to driver element 30 and reverse scrolling, and then reach positioning states, curtain body 21 can arbitrarily be pulled and locate, otherwise during for curtain body 21 is up furled, then up hold up support counterweight 23 again, the retracting strength of elastic threads 32 is made to be greater than the sinking gravity of counterweight 23, allow driver element 30 be able to effective scrolling scroll bar 22 reach curtain body 21 furl concentrate, and decontrol hold up support counterweight 23 time, the sinking gravity of its counterweight 23 then can contend with the retracting strength of elastic threads 32 again, and then stop curtain body 21 to furl formation positioning states, allow the rolled condition of curtain body 21 also arbitrarily can locate restriction, to reach without section and without the curtain using state of stay cord.
Moreover, this curtain sheet unit 20 be with comparatively large-scale curtain body 21 and scroll bar 22 formation time, the strength of its driver element 30 scrolling scroll bar 22 then needs larger, now, promote to reverse by two elastic threads 32 and reply power (shown in Fig. 6), and moving part 31 is axially equipped with four perforation 311 to provide two elastic threads 32 to wear back and forth, and on two shaft lever 12, be relatively provided with two connect apertures 122, to reach the lifting reversing strength.
Another embodiment of its structure, continuing refers to shown in Fig. 7,8, this Window curtain structure separately can be a kind of state of tool Double-layer curtain body 21, wherein curtain sheet unit 20 curtain body 21 end is passed counterweight 23 and is fixed on a cross bar 25, be mounted between two fixed supports 10 by cross bar 25 again, curtain sheet unit 20 to be formed the using state of pair of lamina curtain body 21, when user is launched to use by the drop-down curtain body 21 of counterweight 23, namely its curtain body 21 can be transferred by counterweight 23 and form double-deck state, to promote shading, to regulate the effect of light.
By the structure of above-mentioned specific embodiment, following benefit can be obtained: the utility model is the expansion, the rolled condition that are reached curtain sheet unit 20 by driver element 30, and driver element 30 mainly reverses with tool retracting strength with elastic threads 32 by moving part 31 turn, counterweight 23 that is another and curtain body 21 mutually contends with, pins down, increase the degree of accuracy that curtain uses location, have that group power is simple and easy, advantage easily concurrently, separately can effectively reduce integrally-built cost; Moreover, user directly can reach curtain coiling or expansion by counterweight 23 push-and-pull start, formed a kind of without stay cord and without the using state of section, can not only significantly lift structure use convenience, on the other hand rope hanging can also be avoided to expose and allow baby have to play, the danger of false touch, have security and practicality that structure uses concurrently.
In sum, the utility model has reached breakthrough structural design really, and there is the author content of improvement, the usability in industry and progressive can be reached again simultaneously, and the utility model does not see any publication, also have a novelty, to be correlated with the regulation of law when meeting Patent Law, therefore to propose creation patent application in accordance with the law.
Only above-described, be only a preferred embodiment of the present utility model, when can not with restriction the utility model implement scope; Namely every equalization change done according to the utility model claim with modify, all should still belong in scope that the utility model claim contains.
