Abstract

A string-less cellular or pleated window curtain has top and bottom horizontal beams and pleated curtain between them. The conventional rolling rod tensioned by spring is used to lift up or lower down the curtain without strings. A leading screw is fixed to the end cover of top horizontal beam and engaged with one end of said rolling rod by spiral thread. At another end of the rolling rod there is a movable supporter to lock the spring tensioner to it, allowing the rolling rod to move in top horizontal beam. The lifting rope is wound or dewound around the rolling rod by itself to tension the spring when curtain is pulled down. The tension force of spring is used to lift up the cellular or pleated curtain. The pitch of leading screw can force the lifting rope to be wound by one layer without over lapping. Moving the rolling rod in top horizontal beam can ensure that the bottom horizontal beam at any position can be aligned with the top one.

Description

Cordless honeycomb and pleating curtain

This paper is the U.S. Patent application S.N.08/681 that is entitled as " rolling rod-type cellular (cellular) curtain " that remains to be examined that the present invention applied on July 29th, 1996,910 part continuation application.

The present invention generally speaking relates to curtain, more particularly, relates to a kind of jalousie and partly is the curtain of pleated fabric, and this curtain generally is called cellular and pleating curtain.

The present invention is specially adapted to lift and falls cellular and wireless manual-operating mechanism pleating curtain.Here, the present invention also will describe with regard to this respect.The experts in present technique field can recognize, point of the present invention can expect that the present invention also can be used for electric motor driven occasion with face also more than that, perhaps depend on the spring mechanism of curtain and decide, the present invention can be applicable to the curtain that the jalousie part is not pleated fabric.

The manual operation formula curtain of existing extensive commercialization can be divided into usually rope arranged with wireless two kinds.

Rope formula device is arranged at present generally in order to manipulation activities shutter, cellular curtain, pleating curtain, Thermal insulation curtain, Rome and balloon type (Roman and ballon type) curtain, all these window shade arrangements at least all have two ropes (or a fake) to hang under curtain one side, stretch in the entablature that certain form pulley gear is housed.Be connected on the pulley gear on one group of (general two or three) stay cord, this group stay cord is fixed on the sill by the perforate of shutter or curtain.During pulling side rope, stay cord shortens, thereby sill is drawn on the entablature direction, makes curtain or shutter folding or pleating in the journey last being pulled through.The transverse movement of side rope makes pulley enter locking and lock-out state not, thereby makes the weight of curtain or shutter mat self and fall.If sill imbalance.(venetian blinds generally has Jie's roller rod at the opposite side of entablature, also has the other stay cord, and club impels each blade to open or close when rotating).Have an intrinsic advantage of rope formula curtain to be, the length of curtain can be in full accord with the length of window exactly, can avoid curtain to hold together or flock together at the fully drop-down folded state collection that is when passing through whole window like this.

There have locking that the rope curtain uses and clutch to have to be multiple, many clutch applied springs assist curtain on lift and fall.The United States Patent (USP) 5,228,491 that the example of this type systematic can be presented to people's such as Rude United States Patent (USP) 4,623,012 referring on November 18th, 1996 and be presented to people such as Rude on July 20th, 1997.The rop exercise that has at curtain is done in the mechanism.Lift rope or rope and stay cord in some applications and also be on a static reel or the head's tube that laterally moves.The benefit of horizontal mobile reel is, but stay cord coiled individual layer, and stay cord is around static reel and have multiple around the winding mechanism of horizontal mobile reel.

Though there is rope mechanism to reduce price because of mass production, still somewhat expensive eventually, and also the installation personnel that generally needs to train is installed.In addition, stay cord hangs under the curtain both sides and is most unseemly, and is when especially several windows adjoin installing each other, all the more so.And the security incident that the stay cord that important disadvantages still dangles causes.Industrial quarters has recognized that this problem, and the United States Patent (USP) 3,485,285 of people's such as Hiller United States Patent (USP) 5,133,399, the United States Patent (USP) of Genova 5,485,875 and previous Anderle has all confirmed this point.Recently, association of curtain manufacturer has formally passed through the elimination of formulation among the people or reduce to have formed the safety standard of strangling people's accident that the window control wire of kink may cause, and American National Standards Institute (ANSI) has ratified this standard.

As for Cordless curtain, generally acknowledged selected is that old-fashioned general curtain rolls the rod-type curtain.This curtain is cheap, and house owner or user can install voluntarily, and has broken away from the relevant issues of stay cord.This curtain itself must roll on the bar at curtain and roll, thereby can not be used as venetian blinds, cellular curtain, pleating curtain, Thermal insulation curtain, Rome and balloon formula curtain.In addition, in many this application scenarios, the weight of curtain has surpassed general curtain and has rolled the spring tension that the bar spring produces.In fact, because this restriction, thereby developed the dragline type curtain of being with the spring assisted clutch.

However, the wireless application form of this curtain is stated or attempted to develop to existing skill.The Cordless curtain of prior art is nothing more than belonging to a kind of of following three kinds of different designs methods or classification.

First method is that spring or electric motor driven pulley gear are configured in curtain both sides or curtain entablature outside.Curtain has the situation of point image garage door opening and closing basically by means of lifting on the track that is contained on the window limit and falling.This respect can be referring to people's such as for example Katz United States Patent (USP) 5,141,041, the United States Patent (USP) 4,880,045 of Stahler and the United States Patent (USP) 4,862,941 of Colson.The side guide groove also can be referring to people's such as Carter United States Patent (USP) 4,625,786, the United States Patent (USP) 4,398,585 of Marlow, the United States Patent (USP) 2,325,992 of Wirthman and the United States Patent (USP) 948,239 of McManus.In the United States Patent (USP) 2,324,536 of Pratt, the spring on the pole is contained in the outside of the blade in the lateral column of sealing by means of sill tape moves sill and provides and make the tension force that lifts on the venetian blinds and fall.Side guide in this method makes each device cost bring up to too high and unpractical degree simply, can only be used in specific use.

It is will carry the curtain rope with spring to be wrapped on the sleeve pipe that is contained in the entablature that second method is put it briefly.The United States Patent (USP) 5,482,100 of Kuhar has been introduced a kind of scheme of this method for designing.People's such as Shukat United States Patent (USP) 3,478,875 may be the best file of this scheme basic principle of explanation, and it discloses a kind of bar that rolls around some sleeve pipe pulling ropes.Rope is reeled around self and can not be kept sill parallel with entablature.The United States Patent (USP) 2,276,716 of the United States Patent (USP) 2,037,393 of Roberts, the United States Patent (USP) 2,266,160 of Burns, Cardona and the United States Patent (USP) 2,824,608 of Etten disclose design early.List of references early discloses a kind of venetian blinds with conventional ratchet/pawl spring mechanism, stay cord in each blade upper trapezoid band or strip in this spring mechanism, be wrapped in one be attached to roll keep supplying on the bar lift and the sleeve pipe of the shutter that falls on.In the patent of Etten, stay cord is positioned at the outside.In the patent of Roberts, trapezoid belt itself is wrapped on the bar strip by pulley, and each breach of trapezoid belt is used to change the mechanism that each blade that trapezoid belt fixes is vertically oriented and engages with one.Venetian blinds, even consider the material of modern light weight mini-blind, its weight also still makes to be wanted to select the prestige of conventional ratchet/pawl spring mechanism and steps back.Make and to insert the spring that conventional curtain rolls in the bar and have enough intensity, must fully strengthen the diameter that rolls bar.The degree of depth that shank diameter means necessary corresponding intensification entablature is rolled in increasing, thereby makes it not cross the pass in preceding market now on attractive in appearance.Except that aesthetic problem, one type of prior art syringe can't remain sill and curtain in venetian blinds repeatable operation process to roll bar parallel.The market of today is to allow that width little curtain to 36 inches has 1/4 inch deviation of the alignment at its sill.Even originally one type of prior art syringe can reach such aligning, but, can produce deviation inevitably along with the use repeatedly of curtain.In addition, if misalignment appears in sill, then have no idea to regulate venetian blinds and make sill recover to aim at.

Last a kind of spring pull-down curtain be curtain rod in entablature, laterally move impel hoisting rope curtain fall and on be wound into when lifting on the reel and from reel take off around that is a kind of.Introduced this device in people's such as Hiller the United States Patent (USP) 5,133,399, had on the swift of spiral groove above wherein each hoisting rope is wrapped in twist.When hoisting rope was wound in each groove, the curtain rod that is contained on the platform in the entablature laterally moved in entablature together with platform.It should be noted that the size of swift and the tension force of spring selects to such an extent that its effect is cancelled each other out, thereby make spring tension curtain can be remained on any drop-down position.Although it is doubtful whether the align mode between spring and the reel can keep, swift will inevitably make the excessive unacceptable degree in market to today of entablature together with the size of erecting device.

Main purpose of the present invention provide a kind of adopt conventional curtain roll that bar spring and tensioner spur, fabric portions is pleated and curtain extensible, that can accurately cut into desired length of window.

Above-mentioned purpose of the present invention and other characteristics are to embody so that the window curtain that curtain rolls bar to be housed in a kind of entablature.Curtain rolls bar has a spring and a routine at one end tensioned mechanism, be used for spring in curtain rod tensioning when direction is rotated, and at curtain rod along with spring force has been removed spring tension because of manually along releasing backward rotation that tension direction rotation curtain rod causes the time.Be provided with the curtain fabric that between lower and upper cross-member, extends window is covered with respect to putting the sill that draws on the entablature.The cross section of curtain fabric has such configuration: can be folded into foldable layer when carrying on the curtain, and the complete primary importance that is deployed to when drop-down of curtain, and can further be deployed into the second place when carrying on after curtain is drop-down fully.Have at least the opening of first and second longitudinal subdivisions, one determining deviation setting to pass fabric from bottom to the top stretching, extension of fabric, at least two elevator belts are fixed on also to stretch on the sill and pass the fabric opening, are used for respect to putting the crossbeam of leaving behind on the entablature.Be equipped with a jockey, roll on the bar in order to elevator belt is fixed to curtain, roll on the bar thereby make elevator belt be wrapped in curtain, not only to provide when drop-down a Cordless curtain also to allow curtain fabric to avoid sill at drop-down fully curtain folding fabric to occur in the complete length that has accurately adaptive window opening when drop-down of curtain simultaneously folded thereby carry on curtain.

According to mother's application (S.N.681 of application on July 29th, 1996 the inventor, 910, this application by quote as proof be attached among the application and as the application's a part) in disclosed previous invention, elevator belt contains tape, and these tapes have the eyelet that forms by the distance of increment that increases along its length direction.Bindiny mechanism includes from rolling bar outstanding gear teeth or steering wheel type device and accurately engages with the tape eyelet, thereby guarantee that tape is carried on curtain and be wound into that curtain rolls on the bar when falling equably constantly and from curtain roll bar take off around, thereby keep sill ideally to aim at entablature.

According to the present invention, support belt is a cotton rope, bindiny mechanism comprises a translation mechanism, it is fixed on curtain and rolls on first end of bar, be used for rolling bar and when rotating along clockwise direction, in entablature, vertically promote curtain and roll bar, roll bar at curtain and when rotating in the counterclockwise direction, roll bar along second opposite vertical promotion curtain along first direction at curtain.The second opposed end that curtain rolls bar is provided with supporting mechanism, is used for supporting the relative end that curtain rolls bar in the mode of activity, makes the tensioned mechanism can tensioning spring simultaneously, and drop-down with on remove spring tension when putting crossbeam.Invention formerly is the same, and the present invention provides a kind of size of its curtain fabric can accurately get consistent with the window opening too and fabric can not be crossed the Cordless curtain that diversity is held together when drop-down in that curtain is complete.

According to a key character of the present invention, translation mechanism comprises a threaded bar or leading screw, it can not be rotatably fixed on the end cap of entablature, first end that leading screw and curtain roll bar is threadedly engaged with, thereby make curtain roll bar and carry out lengthwise movement by the pitch on it along threaded bar, pitch is then set to guarantee that hoisting rope is not wrapped in curtain overlappingly with spiral form and rolls on the bar with respect to the diameter that curtain rolls bar, also can keep on any position aiming at entablature thereby sill is at curtain.

According to another key character of the present invention, the relative end that curtain rolls bar comprises a tang, it stretches out from tensioned mechanism, supporting mechanism comprises a supporting bracket, it can move along the bottom of entablature, and the hole that a trough of belt is arranged, described tang stretches and passes this slotted eye, thereby second end that makes curtain roll bar is not only followed screw-driven first end that curtain rolls bar, and provide a firm mounting structure, prevent that curtain from rolling bar at the entablature internal shift, even curtain is drop-down by brute force, no matter what position sill moves to.

Therefore, the purpose of this invention is to provide a kind of Cordless curtain, wherein the curtain fabric of light weight is folded into lamination and stacks between entablature and sill, and curtain on carry with drop-down mechanism because the curtain of the tensioned of the curtain of light weight but a kind of routine rolls bar.

Another object of the present invention provides a kind of Cordless curtain that adopts conventional tensioned curtain to roll linkage, this mechanism all keeps sill to catch up with crossbeam constantly to directly, although curtain maybe may be abused through using repeatedly on any position of curtain.

Another purpose again of the present invention is to provide a kind of Cordless curtain, and wherein entablature has a less cross section and particularly a degree of depth that is not more than the stay cord curtain, can use for conventional dwelling house and commercial window frame.

Another general purpose again of the present invention provides a kind of desirable Cordless curtain attractive in appearance.

Another purpose again of the present invention is to provide a kind of Cordless curtain, and put forward entire mechanism with drop-down curtain on wherein and be contained in the entablature in the window frame of easily packing into, but thereby direct marketing and consumer masses.

Another special and important purpose of the present invention provides a kind of Cordless curtain, thereby wherein dwindles the eyelet that passes curtain to greatest extent with carrying on the hoisting rope with drop-down curtain, and described curtain rolls with conventional tensioned curtain and carries on the bar or drop-down.

Another specific purposes again of the present invention are to provide a kind of Cordless curtain, it adopts a kind of conventional tensioned curtain to roll and carries on the linkage and drop-down curtain, thus wherein hoisting rope with nonoverlapping mode firmly winding of single layer curtain roll shorten to greatest extent on the bar curtain roll bar in entablature move distance so that make on it can be applicable to than possible littler window.

Another specific purposes of the present invention provide a kind of Cordless curtain, this Cordless curtain is fixed to hoisting rope by one and carries with drop-down on its securing curtain rolls conventional spring take-up on the bar, and can regulate hoisting rope curtain roll on the bar the location with guarantee sill and entablature balance or installing after readjust curtain to guarantee sill maintenance and entablature balance.

General purpose of the present invention provides a kind of inexpensive and reliable Cordless curtain.

Referring now to accompanying drawing,, only preferred embodiment in order to demonstrate the invention shown in the figure, rather than limitation of the present invention.Invent probably referring to the mother shown in Fig. 1-3 earlier and can understand the present invention best.For explanation more detailed invention more described here better, can apply for S.N.681,910 referring to the mother that the inventor applied on July 29th, 1996.

Referring now to Fig. 1-3,, Cordless curtain 10 shown in the figure, generally speaking comprise entablature 12, sill 13 and be configured in entablature 12 and sill 13 between curtain fabric 14.

One of basis of the present invention is a specific curtain fabric 14 of selecting to be used for Cordless curtain 10, Cordless curtain is characterised in that, curtain fabric 14i) light weight, and can fold when ii) its cross-sectional configuration is carried on curtain, can extend to primary importance when drop-down in that curtain is complete, when curtain is carried in the preparation, can further extend to the second place after drop-down fully.In Fig. 1, thereby curtain fabric 14 can be regarded as on cross-sectional configuration when curtain fabric 14 is covered the window (not shown) by a plurality of polygonal honeycomb bodies 16 mutual in vertical direction stacked cellular figure that forms respectively, as shown in FIG. in that curtain 10 is drop-down.More particularly, during curtain 10 withdrawals, polygonal honeycomb body 16 is folding, and the fabric that forms horizontal expansion line 18 expressions among Fig. 1 and 2 is folded.Like this, the cellular pattern that is polygonal honeycomb body 16 resembles the accordion flexible, thereby curtain fabric 14 is formed by the fabric of a series of vertically stacked is folded when withdrawal, and the honeycomb matrix of being made up of polygonal honeycomb body 16 when curtain 10 is drop-down is formed.(the honeycomb cross section curtain fabric 14 shown in Fig. 1 and 2 has two row polygonal body 16a and 16b, and the device of female invention is become preferably, but and inessential).In Fig. 1, curtain 10 is in complete pull-down state, and 16 in polygonal honeycomb extends to its normal primary importance.Will on need when carrying curtain further drop-down sill 13 roll the bar spring mechanism usually to start conventional curtain.Polygonal body 16 creates conditions for this further drop-down action, as long as from the vertical direction distortion, curtain is carried, as shown in fig. 1 from complete drop-down position.Like this, because nethermost honeycomb 16 ' can extend in vertical direction by roughly identical with all the other honeycombs degree, thereby curtain 10 can be aligned to perfectly and covers the window opening.Like this, curtain of the present invention is complete does not assemble to hold together together when drop-down under the folded situation about being in above the sill of the fabric that stacks.Open if polygonal honeycomb 16 can not extend from the fully drop-down position of curtain, then increase fabric in the curtain folded 18 (as venetian blinds or Rome curtain take place) possibly, thereby do not attract the consumer in aesthetic.This basic principle of expansion honeycomb is equally applicable to the present invention's pleating curtain fabric shown in Figure 6.

There is one to be that conventional curtain rolls bar 20 fully in the entablature 10.It is to be that the soft-hearted wood curtain of standard null of 1.99 dollars, 11/8 inch of diameter, long 55  inches rolls bar and constitutes with price that the curtain of standard rolls bar.Curtain rolls bar 20 and is equipped with two end cap 22, and supported end bolt head 23 stretches out from an end cap, supports tang 24 and stretches out from another end cap.In fact, the curtain in the preferred embodiment rolls the bar strip that bar 20 is the individual paper formations of circling round.

Referring now to Fig. 3-5,, schematically illustrated the ratchet/pawl device by the spring biasing of the routine that is equipped with conventional curtain to roll bar 20 among the figure.Shown in device in, support tang 24 and extend or form the part of spring lever 26,26 extension one segment distances curtain rolls bar 20 in of spring lever, and its end 28 troughs of belt from spring lever 26.Spring 30 longitudinal extensions are enclosed within on the spring lever 26.One end of spring 30 embeds in the trough of belt end 28, and 32 of another spring terminals are fixed to curtain by strainer or tensioner 31 and roll on the bar 20, and tensioner 31 is contained on the end cap 22, and end cap 22 is press-fitted again and installs to curtain and roll on the bar 20.Be contained on the support and can not rotate owing to support tang 24, thereby spring lever 26 is static.Like this, the curtain rotation of rolling bar 20 is drawn back spring 30 or is compressed.Tensioner or strainer 31 generally are the form of conventional ratchet pawl device, make curtain 10 can be drop-down in the usual way, locking or discharge.

Fig. 4 and Fig. 5 show the ratchet pawl device of two kinds of general prior aries, and the both has a trigger 34, and it is equipped with one or more pawls 35 and can be fixed on the trigger 34 with rivet 36 with putting.Sour jujube plate 38 is fixed on the spring lever 26, its ratchet 39 and pawl 35 engagements, under the situation of spring 30 tensionings, curtain is locked in drop-down position, and makes the tension force of spring 30 when ratchet 39 is decontroled, can equally curtain fabric be recoiled curtain to roll on the bar 20 with routine at ratchet 35.As everyone knows, decontrol pawl 35, supporting is rolled bar and is got further and rotate along tension direction.On the reason wheel, the extremely slight motion of sill 13 will make pawl 35 decontrol.In fact, any people who lifted curtain knows, pawl is decontroled, and curtain is slightly moved down.Owing to the present invention uses for high-grade cellular and pleating curtain to design, thereby can adopt other conventional tensioned mechanism.Conventional expense uncle spring has been shown in Fig. 7 and the preferred embodiment shown in Figure 8 has rolled linkage.The conventional spring 30 that expense uncle's spring rolls linkage has a tensioner 31, rolls the tension force tensioning that makes spring 30 when bar 20 rotates by common mode and loose for curtain.Yet expense uncle's tensioner 31 usefulness bearing (not shown)s replace rolling into and roll out seat ring and curtain rolled bar 20 when curtain rotates and lock and be not locked to pawl on the spring 30.The present invention considers to replace the bearing arrangement that uses among Fig. 4 or ratchet pawl device shown in Figure 5 or Fig. 8 with other conventional spring and tensioned mechanism.For example, can adopt the conventional spring tension device that uses in the spring driven tape measurement mechanism, " buckleing back rapidly " entered the tape measurement mechanism of reel when promptly originally tape pushed back in the box, rather than made when activation button or lever that of tape withdrawal a kind of.Although this another kind of spring drive mechanism not necessarily needs further downward movement to make relative assembly work in sill 13, always can sill 13 is drop-down when consumer masses will decontrol curtain 10.In addition, the curtain that end cap 22, spring 30 and tensioner 31 are housed disclosed herein rolls the device that bar 20 is routine fully.

Referring now to Fig. 2.Curtain rolls that bar 20 can strip, can comprise that two standard-sized spiral fashion so curtain roll bar, and its two end cap of adjoining is unloaded and removed, and is linked together by key bar 40.In the case, a supported end bolt head 23 that rolls bar from curtain gets off together with its relevant end cap 22 removals, removal supports tang 24 rolls bar together with its spring lever 26 and the curtain that adjoins spring 30 simultaneously, it is the same that thereby the curtain that makes curtain roll bar 20 and routine rolls bar, the one end has supported end bolt head 23, and the other end has the tang 24 of support.

Referring now to Fig. 1, Fig. 2 and Fig. 6.Entablature 12 is not high, assemblies fully independently, have Cordless curtain 10, curtain 10 promptly is assembled on the window frame by means of the support (not shown) of entablature 12 by routine, and support is contained on the window frame and can be fixed on the entablature 12 with the known erecting device of any number.The experts that this class erecting device is the present technique field are known, and itself are not again parts of the present invention, thereby do not illustrate here or further describe.

The entablature section bar 44 of entablature 12 is the U font, and the termination is opened wide, and preferably is formed from steel, but also can be molded into by aluminium or plastics.Side bar 46 vertically stretches from the base plate 45 of U-shaped section bar 44, and its top fall home or folding forms groove or groove 48, along the length direction extension of U-shaped section bar 44.

In mother's invention illustrated in figures 1 and 2, bolt head supports end cap 49 closes an end of U-shaped section bar 44, and tang supports end cap 50 closes the other end of U-shaped section bar 44.Bolt head supports end cap 49 has a bearing of journals to accept the supported end bolt head 23 that curtain rolls bar 20 rotationally.Equally, can see the most clearly from Fig. 2, tang supports end cap 50 has the support 53 of a trough of belt, accepts the support tang 24 that rolls bar 20 with the clamping curtain in the mode that can not rotate.Each end cap 49,50 all has suitable supporting construction 54, and every end cap 49,50 can be buckled in the openend of U-shaped section bar 44 simply.

Still referring to Fig. 1 and Fig. 2, sill 13 is to establish for the bottom that is fixed to curtain fabric 14.The sill section bar 65 of sill 13 is the C font, and the termination is opened wide, in case be assembled on the curtain fabric 15, end cap 66 just buckles in place, and the termination is closed.Bottom support sleeve gasket 68 is generally made by the plastic material of PVC (polyvinyl chloride) and so on, slips in the bottom mantle cavity 69 that is formed on curtain fabric 15 bottoms.Bottom support sleeve gasket 68 is placed in the mantle cavity 69 of bottom, and curtain assembles by following mode, comprises being fixed to carrying on the curtain pin 70.Then, sill section bar 65 sliding sleeves to the interior mantle cavity 69 that bottom support sleeve gasket 68 is housed, thereby the top seal of sill section bar 65 is lived, will carry curtain pin 70 and be encapsulated in wherein.Then, buckle into each end cap 66 in place.

Equally, upper support sleeve gasket 72 also is to establish for the last mantle cavity 73 that inserts curtain fabric 15 tops.In described preferred embodiment, will go up the downside that mantle cavity 73 is fixed to entablature base plate 45 with double-back tape.Perhaps, the upper support sleeve gasket 72 in the last mantle cavity 73 also can be the same with bottom support sleeve gasket 68, slips into from the longitudinally extending edge raceway groove that the base plate 45 of entablature section bar 44 extends downwards.Like this, the top of curtain fabric 15 just is fixed on the entablature 12, and the bottom of curtain fabric 15 just is fixed on the sill 13, and this is that cellular or pleating curtain fabric are fixed to entablature and conventional method on the sill or the device that routine has the vertical cellular curtain of rop exercise.

Still referring to Fig. 1-3.In mother's invention, take mechanism's employing on the curtain 10 off and have a plurality of elevator belts 80 of separating the lifting hole 81 of setting by increment along its length.Curtain 10 is equipped with at least two elevator belts 80, every elevator belt be passed on the curtain fabric 14 a series of slits 83 of forming toward each other extension.The bottom of every elevator belt 80 is fixed on the sill 13, and the top of every elevator belt is wrapped in curtain and rolls on the bar 20 and roll on the steering wheel type assembly 84 of bar 20 facing to being fixed to curtain.A plurality of circumference equal intervals configuration, radially the tiller of projection stretches out from steering wheel type assembly 84, roll to accept when bar 20 rotates at curtain and promote hole 80, thus guarantee sill 13 no matter curtain where, no matter be in curtain how can both be accurately and entablature 12 keeping parallelisms by abuse.

Total configuration schematic diagram shown in Figure 6 shows the preferred embodiments of the present invention, for simplicity, the label that is used for indicating each curtain part in female invention also is used for indicating each curtain part of the present invention, in the Cordless curtain 10 of Fig. 6, curtain fabric 14 is represented by dotted lines, and is made up of the pleating curtain fabric.The working method of pleating curtain fabric is identical with cellular curtain fabric with reference to Fig. 1-2 explanation, and when promptly curtain was carried on fully, curtain fabric 14 itself was folded into and stacks layer, extends from above with the such form of accordion when sill 13 moves down.When curtain was drop-down, the pleating curtain fabric folded 16 that at first adjoins entablature 12 extended.If the size of curtain fabric 14 is consistent with window, the bottom of drop-down fully curtain 10 is in abutting connection with each layer expansion a little of sill 13.

In described preferred embodiment, pass the hoisting rope 90 that extends in the hole 91 of respectively restricting and be used for respect to carrying on the entablature 12 and the sill 13 that falls.Like this, the slit of each elevator belt has replaced with less rope hole 91 in the present invention in female the invention.The bottom of every hoisting rope 90 for good and all is solid on sill 13 in any suitable manner.Figure 14 shows the solid a kind of practice of this system.The top of every hoisting rope 90 is wrapped in curtain and rolls on the bar 20, thereby need not to use the reel or the pulley of the specific formation of the steering wheel type assembly of female invention and prior art.In addition, hoisting rope 90 directly is wrapped in curtain and rolls the degree of depth that has just reduced entablature on the bar.

Hoisting rope 90 is fixed to curtain and rolls the mechanism that can adopt any routine on the bar 20.In described preferred embodiment, 94 of rope clamps shown in having an X-rayed among Figure 10 are anchored to curtain simply and roll on the bar 20, as shown in Figure 6.Rope clamp 94 be wrapped in curtain and roll width that at least one circle hoisting rope 90 on the bar 20 is connected and give the initial installation of sill 13 and provide a mechanism easily with respect to the adjustment of entablature.Importantly, need to adjust after installing as curtain 10, then rope clamp 94 is carried out this adjustment.

In described preferred embodiment, the support tang 24 that stretches out from tensioner 31 is fixed on the travel(l)ing rest 96.Travel(l)ing rest 96 shown in the perspective view of Figure 11, has a slotted eye 97, and support tang 24 promptly passes this slotted eye 97 and stretches out, and is fixed on the travel(l)ing rest 96 by resembling any proper device of split pin 98 and so on.In described preferred embodiment, travel(l)ing rest 96 has two triangle booms 99 that can move along the base plate 45 of entablature 12.In another embodiment shown in Figure 12, triangle boom 99 can replace with roller 100.In above-mentioned two embodiment, slotted eye 97 prevents to support same mode that tang 24 rotates with slotted brackets 53 in the entablature end cap 50 of mother invention and fixes and support tang 24 and make its unlikely rotation.Travel(l)ing rest 96 makes curtain roll bar 20 and can vertically move along base plate 45 in entablature 12.

Screwed end plug 102 curtain of packing into rolls on the relative end of the end with spring 30 and tensioner 31 are housed of bar 20, its screwed hole as shown in Figure 9 so that with the leading screw guiding end frame 106 (as shown in Figure 13) that for good and all is fixed to entablature 12 on being threadedly engaged with of leading screw 104.Leading screw 104 can not rotate, and for good and all is fixed on the leading screw guiding end frame 106.Like this, curtain rolls bar 20 and impels leading screw 104 to move forward in the threaded end plug 102 along a direction rotation, and curtain is rolled bar 20 pull to leading screw guiding end frame 106 together with travel(l)ing rest 96, simultaneously the curtain backward rotation of rolling bar 20 impels threaded end plug 102 to retreat with respect to leading screw 104, has increased curtain and has rolled bar 20 and leading screw and guide spacing between the end frame.Curtain rolls bar 20 and is being equipped with another support 108 near plug 102 places, threaded end.Whether need this another support 108 and this support should be placed on which position, be determined on a case-by-case basis, and depend on curtain to roll the length of bar 20 and decide.

Importantly, the size of the pitch of leading screw 104 is to consider that according to the circumference that curtain rolls bar 20 diameter of hoisting rope 90 chooses, make hoisting rope 90 can individual layer reel voluntarily and take off around, or be wound on the circumference that curtain rolls bar 20 with nonoverlapping form.Because the pitch of leading screw 104, hoisting rope 90 can be all the time be wrapped in curtain with the form of spiral and rolls on the bar 20.As long as hoisting rope 90 is not intertwined each other voluntarily, sill 13 will be positioned on the same position always.

The circumference that the curtain of the standard specification that conventional diameter is about 1 inch rolls bar is bigger.Compare with the curtain mechanism of existing stay cord operation, this diameter of 1 inch does not increase the degree of depth or the height of entablature 12.If what influence is arranged, then be to have dwindled section.Simultaneously, the curtain that diameter is bigger rolls bar 20 and can reduce hoisting ropes and be wrapped in the number of turns that curtain puts curtain 10 on rolling on the bar.Twine the number of turns and reduced and mean that having reduced curtain rolls the amount of exercise of bar 20 entablature 12 in, thereby can adopt the curtain of with respect to the overall width of curtain fabric 14, relatively lacking to roll bar 20 in the present invention.Tensioning spring 30 is about 9 inches, and best mode with routine is placed in curtain and rolls in the bar 20 to dwindle the section of entablature to greatest extent.Because curtain rolls the finite motion of bar 20 in entablature 12, thereby curtain of the present invention can cover narrower window.In addition, the present invention also has a delicate benefit: the amount of exercise that rolls bar 20 owing to curtain is less, thereby has promoted the fault-free running in the length of life of curtain 10.

Volume is put easy curtain hoisting mechanism

A) volume put simple and easy mean to carry with drop-down pleating and cellular fabric curtain need not to use conventional cotton rope or lift part or locking piece.

This system makes the operating process of curtain almost identical with the operating process that conventional spring rolls the bar curtain.Slowly spur sill, curtain is just unfolded and rest on the desired length.Drop-down action can make the spring that is engaging roll the bar pawl to break away from ratchet, the tension force of spring sill will be mentioned carry the position up to hand brake or on entering fully till.

This volume is put easy hoisting mechanism and is intended to solve following four problems:

1) safety problem, it is the danger that control wire blocked or strangled of playing that the present invention has eliminated children.

2) make things convenient for problem, control wire often will be wrapped on the drift bolt after curtain regulates.Twining rope makes its unlikely hanging on the ground down will spend extra time and energy.

3) aesthetic problem, many people find to hang under the cotton rope attractive, decorative effect that impairs pleating or cellular curtain fabric.Volume is put easy hoisting mechanism and has been eliminated manipulation device to the pleating generation vertical direction of the level of these fabrics peptizaiton.

4) continue alignment issues, the curtain of conventional belt locking mechanism can not keep aiming at frequently, thereby makes the sill imbalance.Volume is put easy curtain hoisting mechanism and is remained balance.

B) the described spring that the objective of the invention is to make the curtain rope can be wrapped in dress in constantly in a predetermined manner equably voluntarily rolls on the bar.

Volume is put easy curtain hoisting mechanism and is utilized a spring to roll bar combine with the screw thread guiding device to make and self carry out screw and do not lay down its in advance tension force of setting.This realizes by rolling bar outfit spring locking saddle, threaded end plug and corresponding leading screw guiding end frame for pre-setting spring.

C) to roll the tension force of bar be that tang by clockwise direction rotation spring mechanism causes a resistance that is directly proportional with the weight of fabric of intending carrying and sill and sets up in advance up to reaching to spring.

The spring terminal that rolls bar is fixed on the sliding support by the split pin of tang of passing spring and rolling the pre-drilled hole of linkage.This threaded end plug replaces conventional spring to roll the pin end plug of bar.This threaded end plug inserts roll bar in relative with spring mechanism, and to be received in the leading screw that the leading screw guide end covers, the number of threads of the per inch on the leading screw is being arranged spring and rolled the distance that will walk when bar rotates.

Rotating speed gives one group to be fixed to the cotton rope that rolls on the bar a measurable and uniform winding is provided to the ratio of travel distance.These cotton ropes have replaced the conventional fabric that rolls the bar curtain to come concrete driving spring to roll bar.The length of cotton rope is that the length that curtain is predetermined adds that width and 12 inches other (were called to extend and drive length) calculate.Rope clamp is used for cotton rope is fixed to the position of rolling bar that overlaps with the cotton rope guide hole that pierces the entablature bottom.

The position of cotton rope guide hole general with each end of entablature equidistantly and be on the center line of the degree of depth of entablature, relevant with the top of the pleating or cellular fabric of cotton rope sliver and compression.Under the situation of all guide hole alignment, fabric attaches to the bottom side of entablature, and the cotton rope sliver attaches to the bottom of fabric.Online rope clamp is under the situation of rolling on the bar, and relative termination is passed entablature cotton rope guide hole inboard, passes the fabric of compression, passed sliver.

Roll before lever system puts into entablature at spring, order is rolled lever system and is rotated with respect to the spring terminal clockwise direction.This manual rotation operation twines cotton rope and rolls bar roughly three times, so that primer spring rolls bar.At this moment, whole spring rolls lever system and is placed in the entablature, and the snug fit by the leading screw guide support is fixed in the openend of entablature.The entablature end cap is fixing in the same way, has just finished so furl easy entablature system.

Be reduced at fabric pressing under the situation on the bottom side of entablature, be parallel to entablature each cotton rope is pulled in together gently, so that be fixed on the end cap of sill.Come out to see it is that farthest cotton rope seems the shortest from guide hole by rope group pulling direction.All other each ropes all cut into this cotton rope evens up, and is fixed to sill end cap inboard together.

Sill is set on the cotton rope sliver, and each cotton rope comes out from the other end.Giving enough pulling force to cotton rope just makes spring roll the bar starting.This cotton rope guiding will be passed the cotton rope sliver sealed up opening raceway groove, pass fabric, introduce in the entablature, be wrapped in equably and roll on the bar, till the sill end cap is seated in the openend of sill voluntarily.With the other end of second end cap sealing sill, whole curtain just assembling finishes.

Another characteristics that volume is put simple system are the minimum widiths that reduced curtain, and 16 inches that find from most of clutch actuation systems narrow down to roughly 12 inches.The spring that cotton rope is wound into 1 inch diameter rolls on the bar, on the axle compared with 3/8 inch diameter that is wound into clutch system, in entablature required traverse stroke short half have many.These diameters be multiply by 3.1416 respectively just draw corresponding circumference.This calculating shows, promote 3.1416 inches curtain, and volume is put simple system only need change 1.0 circles, and by contrast, the clutch system that promotes same height then needs to change 2.6166 circles.The traversing distance of rolling up this shortening of putting simple system just makes the minimum widith of curtain can contract narrowlyer.

Two accessory claims that volume is put simple system are included in to be used spelling joint to connect two when curtain surpasses the length that stock rolls bar to roll bar.In addition, roll shaft bar in the employing of splicing position, if possible below rolling the threaded end plug side of bar.

D) invention in past has proposed spring and rolls bar and be used in combination with venetian blinds.Yet, the shortcoming of this combination, spring becomes obvious with regard to fail to start when resting on fully the position of the final shutter length of launching owing to shutter.Volume is put simple system and has been utilized the folding property of the concertina of pleating or cellular fabric to solve this problem in conjunction with crossing extension driving length, so just can roll bar by primer spring under the situation that surpasses the predetermined final curtain length of curtain.

Different with the venetian blinds of routine, the weight of pleating or cellular fabric is with traditional to roll the bar curtain fabric consistent.

Previous invention has emphasized that uniformity that cotton rope twines cancelled stay cord with sill that level is provided and for the reason of safety.We believe volume put simple system can meet economical and practically above-mentioned standard on the commercial and domestic use.

In the view of the consumer, the present invention is duplicating of existing stay cord curtain, and various curtain seem mutually the same, are a kind of rope that has, and are a kind of wireless.Two kinds of curtain all have lifting device to pass through its pleating fabric extension, and both can regulate in installation process and after installing.Two types curtain all can provide the zero defects running in its whole service life in the process, both can both keep sill to be parallel to entablature.But compare with the stay cord curtain, the cost of curtain of the present invention has descended greatly.The more important thing is the hoisting rope that is safe from danger.

The present invention is described in conjunction with a preferred embodiment.Obviously, the experts in present technique field will be apparent from later on and can change and improve it reading and understand above-mentioned detailed description of the present invention.The present invention includes all these changes and improvement, as long as these changes and improvement fall within the scope of the invention.
