Description
Background note
Technical field
This novel shutter that is relevant to, the operating system that particularly is relevant to a kind of compound shutter can improve controlling of shutter and and then provide a polynary shaded effect.
Background technology
Shutter as vane type curtain and door curtain, is commonly used to window shading, purposes such as spatial separation because of it has characteristics easy to operate and attractive in appearance.Common vane type curtain comprises rail on, rail once, some are hung net and are suspended on this and are used for flatly hanging the anti-dazzling screen that is fixed on these some suspension strops and is vertical arrangement between the rail and this time rail, its middle cover anti-dazzling screen moves up and down by a Hoisting System, and these some anti-dazzling screens can play different shaded effects along with suspension strop rotates freely.
Here, thus this Hoisting System is to be used for that this time rail is risen to certain altitude to allow the user expose the window that is covered by shutter selectively.Usually, Hoisting System includes a series of ropes of controlling, and controls rope by spurring these, and the user can adjust the height and the shading state of shutter.
Usually, the last rail of shutter is that the U type groove of an elongated is used for supporting an axle suspension net, and this U type groove has at least one opening allow to control rope by handling anti-dazzling screen.
But this traditional vane type curtain also exists a lot of defectives and deficiency.At first, when all anti-dazzling screens are pulled to the top, external light can be too strong, and individual privacy can not be protected fully.On the contrary, if all anti-dazzling screens are pulled to the bottom, light again can be too dark, and the user has to replenish light by some lighting apparatuss.Also have, when all anti-dazzling screens rotate to certain angle so that light when can enter between per two anti-dazzling screens, because the distance between the anti-dazzling screen is formulated by manufacturer, the light that can enter the room is limited.If the user has selected the bigger vane type curtain of a kind of anti-dazzling screen spacing, when he enjoyed abundant light, his privacy just must not be adequately protected, because can see some inner scenery from the external world.
Because traditional vane type curtain has significant limitation in the use, the user must make choice on light and privacy.So, can locally open and close in order to provide a kind of, and can provide the duplex blade curtain of different shaded effects, need a kind of novel duplex blade curtain on the market, it comprises the diaphragm system of two cover independent operations at least, extend from top to bottom respectively, and comprise two the cover suspension be used for flatly supporting a plurality of anti-dazzling screens, and can arbitrarily change the anglec of rotation of a plurality of anti-dazzling screens, because two cover suspension are for vertically being staggeredly placed, near each anti-dazzling screen of the first cover diaphragm system and the second cover anti-dazzling screen, thereby so the user can adjust two cover diaphragm systems respectively according to different needs and make the light that can pass in and out according to own wish variation.Usually, when the vane type curtain was opening, light can enter from the spacing between two anti-dazzling screens, but have two the cover diaphragm systems the vane type curtain light is entered from the space that doubles two spacings between the anti-dazzling screen.That is to say that this duplex blade curtain has one and becomes the control suspension and only support the second cover anti-dazzling screen, by spurring this changes control suspension, second overlap anti-dazzling screen can with the overlapping change shading of adjacent anti-dazzling screen state.
The suspension of vane type curtain traditionally be the suspension net of a thin-and-long, it comprises two ladder ropes that extend from top to bottom, the horizontal rope that is used for being connected two ladder ropes with many horizontal equidistant intervals, thereby form a plurality of equidistant spacings ladder band grid, the anti-dazzling screen that can guarantee a plurality of standards of tolerance like this spacing can be arranged places in the ladder band grid, and the system that is draped supports, be the rightabout interaction by operating two ladder rope in the vertical directions artificially, can have adjusted the angle that places a plurality of anti-dazzling screens in the suspension.
Usually, the top of every sleeve configuration suspension net all can be shunk and be become a hoisting rope.Theoretically, by spurring this hoisting rope, change the control device and can be pulled up the distance that changes between the anti-dazzling screen.
For easy to use, this hoisting rope is drawn and is free hanging state from last rail and is beneficial to the user and spurs this hoisting rope.In addition, this hoisting rope is placed in a side of window, and this hoisting rope of coming of hanging down just can not influence light and enters this window like this.In general, the user can select the left side or the right side that allow this hoisting rope place window.
Unfortunately, the hoisting rope as for side can cause certain worry to the user.
For the window of a relative broad, have usually a lot of ladder ropes with interval from the shutter rail hang and be used for balancedly hanging anti-dazzling screen.But, in case the hoisting rope that overhangs is pulled and the ladder rope of hoisting rope close together will be born stronger tension force.On the contrary, the ladder rope of far-end can be born lighter tension force again.Concerning a user, more balancedly promoting change control system can be a cumbersome thing.In most cases, change the control suspension and when pulling, can produce an angle of slope.
In addition, also can correspondingly to have a lot of openings corresponding with the ladder rope that becomes the control suspension for the turnover of ladder rope in the bottom of rail on the shutter.But being lifted under the situation of bearing tension force and last rail repeated friction, can be to reduce greatly in the life-span that promotes.Although can increase pulley gear, still do not give birth to upward rail groove of assurance ladder rope turnover freely at these opening parts.Because unbalanced tension force causes the terraced rope tension nearer apart from hoisting rope excessive and damage forever.
Simultaneously, the hoisting rope that preamble is mentioned and control rope and all use and promote lock, this liftings lock is fixed in and is used for fixing hoisting rope in the rail and controls the mobile of rope.In general, control rope and run through whole anti-dazzling screens and last rail, and draw from an end of last rail and to become to overhang state from following rail.
Rope promotes lock and comprises a lock chamber, one fixed rotor places on the diameter of axle of this lock chamber rotationally, also have a floating gear to place this lock indoor mobile between a latched position and non-locked position movably, wherein hoisting rope is used for promoting this floating gear and is displaced to latched position from non-locked position from streaking between fixed rotor and the floating gear.When non-locked position, hoisting rope can streak the lifting of adjusting anti-dazzling screen from floating gear, and when latched position, thereby this floating gear is squeezed at fixed rotor and lock and hoisting rope is clipped between fixed rotor and the floating gear between the chamber interior walls.
Unfortunately, in case when this lifting lock was used for pinning whole change control suspension, this liftings lock will bear the weight of whole change control suspension, that is to say, floating gear can be moved down any by this weight drive and block hoisting rope.For the common rope of controlling, the playback of floating gear can make to be controlled rope and is stuck in more tightly between fixed rotor and the floating gear.But for becoming the control suspension, thereby its role is to summer displacement on half the anti-dazzling screen of shutter and second half anti-dazzling screen are overlapped to form better shaded effect.So the playback of the floating gear in the lifting lock can make this open slightly with overlapping anti-dazzling screen and destroy whole shaded effect.
Therefore, imperative to the improvement of this duplex blade curtain.

The specific embodiment
As shown in Figure 1, this novel preferred embodiment provides a kind of duplex blade curtain.Wherein this duplex blade curtain 1 includes last rail 10, one following rails 20 that place rail 10 belows separated by a distance that are fixed in ceiling or wall top, and a plurality of anti-dazzling screen 30 that spacing is arranged places between rail 10 and the following rail 20.
In addition, duplex blade curtain 1 also comprises a curtain shutoff device 40, it comprises a pulley system 41 that places on the rail 10, article one, control rope 42, this is controlled rope 42 and comprises a lift portion 421 of extending and linking to each other with pulley system 41 from last rail 10, and one extend the folded part 422 of supporting a plurality of anti-dazzling screens 30 in order to hang between last rail 10 and following rail 20, wherein when controlling rope 42 lift portion 421 and spurred from last rail 10, thereby following rail 20 can be raised and makes a plurality of anti-dazzling screens 30 overlapping between last rail 10 and following rail 20.
Simultaneously, duplex blade curtain 1 also comprises a shading and improves device 50, it comprises a plurality of auxiliary anti-dazzling screens 51 that place between rail 10 and the following rail 20, wherein each auxiliary anti-dazzling screen 51 all is placed between per two adjacent anti-dazzling screens 30, with one improve control system 52, wherein this improves control system 50 and comprises a control slide block 521 that is fixed in slidably on the rail 10, one is used for improving at a shading position and a light from control slide block 521 extended anti-dazzling screen adjusters 522 and regulates auxiliary anti-dazzling screen 51 between the position, article at least two, be used to support each auxiliary anti-dazzling screen 51 from control slide block 521 extended sleeve configuration elements 523, wherein when the shading position, thereby be hung in by pulling control slide block 521 with can making auxiliary anti-dazzling screen 51 alternate intervals and stop fully between per two anti-dazzling screens 30 that light enters from the space between per two anti-dazzling screens 30, and improve the position at light, thereby every auxiliary anti-dazzling screen 51 and every adjacent anti-dazzling screen 30 overlapping light that make are entered from the space between per two anti-dazzling screens 30 by pulling control slide block 521.
Here, thus improving control system 52 is to be used for improving the shaded effect that traditional shutter produces a variation.Generally speaking, a plurality of anti-dazzling screens 30 are hung on the ladder rope that places between rail 10 and the following rail 20 independently.In order to control and produce the shaded effect of a conversion more easily, this novel duplex blade curtain 1 provides a series of auxiliary anti-dazzling screens 51 to be clipped in respectively between per two adjacent anti-dazzling screens 30, thereby wherein auxiliary anti-dazzling screen 51 can be promoted by at least two sleeve configuration elements 523 or descend and the adjacent corresponding anti-dazzling screen 30 overlapping spacings that increase between the anti-dazzling screen 30.
More satisfactory ground, anti-dazzling screen 30 and auxiliary anti-dazzling screen 51 are same model, the anti-dazzling screen of size.That is to say that anti-dazzling screen 30 here and auxiliary anti-dazzling screen 51 are supported by same ladder rope, just auxiliary anti-dazzling screen 51 is improved control system 52 by another one and supports to improve shaded effect.
Perhaps, improve control system 52 and can regard another set of anti-dazzling screen suspension arrangement as and be used for auxiliary traditional anti-dazzling screen suspension and be used for together support part anti-dazzling screen 30, more satisfactory ground is used for supporting half anti-dazzling screen 30.So in case the sleeve configuration element, by length travel, half anti-dazzling screen 30 is just assisted anti-dazzling screen 51 as ladder rope 523, or upwards, thereby the spacings between the downward and neighbour anti-dazzling screen 30 overlapping adjustment anti-dazzling screens 30.
Novel according to this, the U type groove that last rail 10 is a sleeve configuration is provided with plurality of openings 101 and is beneficial to pass ladder rope and the sleeve configuration element 523 that is used to hang anti-dazzling screen 30 in the bottom of groove.As a rule, to general window, sleeve configuration element 523 may be embodied as two ladder ropes that extend from last rail 10 from top to bottom.What deserves to be mentioned is that for some special anti-dazzling screens, the anti-dazzling screen made from woodwork and epoxy resin for example, sleeve configuration element 523 that places the anti-dazzling screen middle part just can support fully and anti-dazzling screen is assisted in displacement.
Simultaneously, the last rail of 10 traditional venetian type shutters of last rail of the U type groove shape of sleeve configuration can be fixed on the ceiling and the upper end of window.Plurality of groove lower ending opening 101 is for corresponding with the sleeve configuration element 523 that improves control system 52.
As shown in Figure 2, an axial stem 102 rotatably is fixed on the U type in the rail 10, wherein controls slide block 521 and is placed in slidably on the axial stem 102.In this novel preferred embodiment, control slide block 521 comprises a pair of coaster 5211 has spacing ground to be placed in slidably on the axial stem 102, is used to be connected two coasters 5211 with a reinforcing rod 5212.Just because sleeve configuration element 523 comprises at least two ladder ropes that place the shutter both sides respectively, so the control slide block 521 of a prolongation can increase the moment of torsion of pulling far-end ladder rope effectively.That is to say that comprised every ladder rope of described sleeve configuration element 523 all distinguish accordingly and linked to each other with the coaster 5211 of a close together, the upper ends that the control slide block 521 of prolongation can make two ladder ropes in last rail 10 by opposing parallel spur.
What deserves to be mentioned is that for the window of broad, described sleeve configuration element 523 can comprise a plurality of ladder ropes and guarantee that auxiliary anti-dazzling screen 51 is hung in rail 10 more evenly and goes down on one's kness between 20.So control slide block 521 will include a plurality of coasters 5211 accordingly and spacing is arranged be placed on the axial stem 102, simultaneously, reinforce rod 5212 at least two and can be used to connect a plurality of coasters 5211.
In addition, improve control system 52 and also comprise compartment system 524, it comprises in the lower ending opening 101 that a plurality of sliding bolts 5241 laterally place rail 10 on each, thereby wherein sleeve configuration element 523 passes through rail by sliding bolt 5241 slidably and reduced friction.
According to this novel preferred embodiment, the anti-dazzling screen adjuster 522 that improves in the control system 52 is a hoisting rope 5221, the side that this hoisting rope is connected in control slide block 521 is used for moving control slide block 521 along axial stem 102, so whenever hoisting rope 5221 when pulled, control slide block 521 can be strained sleeve configuration element 523, and pulling sleeve configuration element 523 promotes or the auxiliary anti-dazzling screen 51 that descends reposefully along sliding bolt 5241.
As shown in Figure 2, thus the coaster 5211 of control in the slide block 521 is to be placed in axial stem 102 rotationally and slidably to join with the ladder rope of sleeve configuration element 523 accordingly.In this was novel, the quantity of coaster 5211 was identical with the ladder rope quantity of sleeve configuration element 523, and for the window that generally has two ladder ropes, it is corresponding with it that control slide block 521 has two coasters 5211.For the window of broad, it is corresponding with it also just to have more coaster 5211.Reinforcing rod 5212 is to be used for guaranteeing that control slide block 521 is a global facility.In addition as shown in Figure 2, the coaster 5211 of control slide block 521 is to be enclosed within on the axial stem 102.
In this was novel, the purpose of compartment system 524 was to alleviate the frictional force in sleeve configuration element 523 moving process.Every ladder rope in the sleeve configuration element 523 all links to each other with the coaster 5211 of control slide block 521.Simultaneously, the opening 101 of last rail 10 bottoms and the alignment of the ladder rope in the sleeve configuration element 523 are so terraced rope can pass through flange of rail end at an easy rate.
But the control slide block 521 during this is novel is not that long enough can guarantee that coaster 5211 can align with last flange of rail end opening 101 respectively and vertically.In case control slide block 521 be pulled, inevitably, the sleeve configuration element 523 of lateral displacement will with the edge friction of bottom end opening 101.So the sliding bolt 5241 of compartment system 524 is to be used to overcome this frictional force.Here, every sliding bolt 5241 is implemented as the rod iron that lies across bottom end opening, in a single day so control slide block 521 by displacement, the sleeve configuration element 523 of advancing up and down can slide along smooth relatively rod iron.
In order to guarantee to improve the quiet run of control system 52, compartment system 524 also comprises a location fastens 5242 and crosses on the two side of rail 10 on the U type, and place control slide block 521 near.So a terraced rope of sleeve configuration element 523 can be walked around this location and fasten 5242 and reach a comparatively ideal moment and spur auxiliary anti-dazzling screen 51.
For the reason of simple installation and easy operating, control slide block 521 is placed in an end of shutter.For no other reason than that will extracting from the control slide block, anti-dazzling screen adjuster 522 is used for regulating shaded effect.As shown in Figure 2, control slide block 521 is placed in the upper left corner of shutter, and sleeve configuration element 523 has two ladder ropes and links to each other with control slide block 521 respectively.Clearly the control slide block 521 of shifted laterally can not provide an effective moment to spur the ladder rope 5231 of the leftmost side.Because should ladder rope 5231 just in the lower end of control slide block 521, laterally the pulling force of pulling can not become the torsion of vertical pulling ladder rope 5231 effectively.So in order to change horizontal kinetic energy into potential energy longitudinally, this novel location that provides fastens 5242, wherein article one ladder rope 5231 can be walked around this location and fastens 5242 and obtain a bigger moment.Through such winding, every terraced rope can divergently extend from control slide block 521.
As shown in Figure 2, article one ladder rope 5231 of sleeve configuration element 523 is placed in the left side and walks around the location and fasten 5242, so in case control slide block 521 to left dislocation, the upper end of ladder rope 5231 will be tightened up, and will become parastate through the ladder rope that detours with another terraced rope.Here, fasten 5242 through the location earlier near article one ladder rope 5231 of control slide block and detour, and then oppositely extend through the sliding bolt 5241 that is located on the bottom end opening 101 and realize that a comparatively ideal moment promotes auxiliary anti-dazzling screen 51.
In other words, in case control slide block 521 is spurred by anti-dazzling screen adjuster 522, the coaster 5211 of control slide block 521 will spur different ladder ropes relatively.Simultaneously, according to the position of control slide block 521, the canoe of sleeve configuration element 523 also can be different, if the control slide block is placed in the right side of shutter, the coiling of ladder rope will from the other direction around.
This anti-dazzling screen adjuster 522 in novel comprises also that a locking device 60 is used for stoping and adjacent anti-dazzling screen 30 overlapping auxiliary anti-dazzling screens 51 can not playback under light improves the state of locking position control slide block 521 original position goes to influence between per two anti-dazzling screens spacing.
