Description

Curtain, especially venetian blind

field of use

The invention relates to a curtain, in particular a venetian blind, with guide and deflection elements for the pull cords attached to the curtain material, the fastening material with rings or eyelets carrying the curtain material being fastened by means of an adhesive fastener tape to a mounting rail firmly connected to the building.

State of the art

From DE 37 14 105 a gathering curtain with guiding and deflecting elements for the pull cords attached to the curtain material is known, in which each deflecting element consists of a fastening plate connected to the curtain material, which is preferably made in one piece with a guide eye hanging from it is firmly connected. The curtain material carrying the fastening plate with the eyelet is fastened by means of a textile adhesive fastener tape to the mounting rail which is firmly connected to the building. The curtain is thus attached to the mounting rail by means of an adhesive fastener tape, which consists of a fleece tape and a Velcro tape. The fastening plates with the eyelets for the pull cords are fastened to one part - fleece band or Velcro band - of the adhesive fastener band, which in turn is brought into adhesive connection with the other part, which is fastened to the mounting rail. However, this design can only be used with light-weight materials. When heavy curtain fabrics are used, the tensile force caused by the high weight affects the adhesive connection, with the result that the fleece tape detaches from the Velcro tape of the adhesive tape due to the strong pull.

Task, solution, advantage

The object of the present invention is to provide a curtain of the type mentioned at the outset, also using an adhesive fastener tape for heavy curtain fabrics, in which the tensile forces caused by the curtain weight do not act on the adhesive fastener tape, but are guided into the fastening system on the building become.

This object is achieved by the features characterized in claim 1.

Thereafter, the invention consists in that the fastening plates for producing a non-positive connection are connected to the support rail attached to the building by means of detachable support and connection elements which absorb vertical tensile forces.

These support and connecting elements consist of a horizontally extending web fastened or molded on each fastening plate and of an engagement groove for the fastening plate webs formed on the mounting rail and running in the longitudinal direction of the mounting rail. The engagement of the webs of the fastening plates in the engagement groove on the mounting rail creates a non-positive connection which otherwise affects the adhesive force. tensile forces acting on the closing band are conducted via the supporting and connecting elements into the supporting rail and are thus absorbed by the building wall to which the supporting rail is attached. In this way, unintentional loosening of the adhesive tape is avoided, since the tensile forces caused by the curtain weight are no longer conducted into the adhesive tape. There is thus no longer any tensile load on the adhesive fastener tape.

Advantageous embodiments of the invention are characterized in the subclaims.

Here, the design of the mounting rail, which has a web-like cross-sectional profile that extends from a first U-profile with horizontally running legs and one connecting them, with a first section beyond the lower leg, is particularly advantageous Web, wherein the upper horizontal leg is led with a section over the leg connecting web and the free ends of the legs have mutually facing, angled sections, and a second, running parallel to the first section, at the free end of the lower leg of the first There is a U-shaped section, the first section having at its free end a U-shaped third section forming the engagement groove for the fastening plate webs with an outwardly directed fastening plate web engaging opening, and the third, on both sides of the first web section extended section and the free lower end of the second section has sections which face one another, forming an opening, the sections in the support Rail-shaped openings serve to receive the fastening device for the winding shaft for the curtain material and for the fastening device of the mounting rail on a building wall.

A further embodiment of the invention consists in that each deflection element consists of a fastening plate which is itself firmly connected or detachable to the curtain fabric, which in turn is firmly connected to a guide eye which hangs from it and is made in one piece therewith, a two-part design also being possible .

The invention further relates to a curtain, in particular consisting of a fastening rail which can be fastened to a wall or the ceiling of a room, with a curtain fastened thereon with its upper edge and with a plurality of groove-shaped guides running in the longitudinal direction of the fastening rail for receiving at least two coil housings or holders each with a winding shaft running transversely to the longitudinal direction of the fastening rail and carrying a sprocket on one end and with an endless operating chain that is operatively connected to the sprockets of the winding shafts, connected to a drive and deflected at one end of the fastening rail, and for opening ¬ Assumption of the chain dreams of the operating chain, wherein the winding shafts that can be actuated via the operating chain are used for winding up pull cords, which have one end on the winding shafts and the other ends on the lower edge of the curtain established and are guided by guide loops distributed between the upper edge of the curtain on the curtain. In this curtain, according to a first embodiment, at least two first bobbin housings with winding shafts and chain wheels for the pull cords attached to the lower edge of the curtain for gathering and unwinding the curtain are arranged on the underside of the fastening rail, the chain wheels of the winding shafts of the first bobbin case one of the two long sides of the fastening rail and is operatively connected to a first, endless operating chain with chain runs guided in guides of the fastening rail. The guidance of this first control chain is such that it runs parallel to the vertical longitudinal side edge of the curtain with a control chain section. Furthermore, a second bobbin case with a winding shaft and a chain wheel for a pull cord attached to the lower edge of the curtain for fan-like gathering of the curtain is arranged on the underside of the fastening rail. The sprocket of the winding shaft of this second spool housing lies on the longitudinal side of the fastening rail facing away from the sprockets of the winding shafts of the first spool housing. The sprocket of the winding shaft of the second bobbin case is operatively connected to a second, endless operating chain with chain runs guided in guides of the fastening rail. The arrangement and guidance of this second fastening chain is such that it comes to lie on the side of the curtain with an operating chain section that runs parallel to the vertical longitudinal edge of the curtain on which the operating chain section of the first operating chain also runs, so that the curtain is operated via operating chain sections lying on one side of the curtain. The first operating chain is used to gather and unload the pre hangeε, while the curtain is actuated by means of the second operating chain so that a fan-like gathering of the curtain is possible, the fan-like gathering of the curtain being reversed when the direction of movement of the operating chain is reversed.

According to the further embodiment of the invention, the gathering curtain has approximately the same design and arrangement as described above, but the two control chains with their control chain sections are guided in such a way that the one control chain section on one side of the curtain and the another operating chain section comes to lie on the other side of the curtain, so that the operating chains must be operated on two different sides of the curtain.

Since the bobbin cases with the winding shafts and the chain wheels are of the same design, the bobbin cases can be placed on the left side and sometimes on the right side on the underside of the fastening rail, where they are held in the guide / holder provided in the guide rail by means of a clamp seat are that both a loosening and a displacement of the coil housing on the fastening rail is possible. However, the arrangement of the coil housing on the fastening rail is such that, in the attached position, the coil housing on the fastening rail is locked against displacement at the same time in order to prevent the winding shafts from being actuated when the chain wheels are actuated the coil housing by means of the operating chains the coil housings move automatically on the fastening rail. The possibility of being able to gather and remove a curtain on the one hand and to gather the same curtain like a fan on the other hand is achieved in that the coil housings provided for the gathering and unrolling of the curtain are arranged on the fastening rail in such a way that the sprockets of the winding shafts of all of these coil housings lie on one long side of the fastening rail. The coil housings responsible for the fan-like gathering are then arranged so that their sprockets of the winding shafts for the corresponding chain hoist lie on the other long side of the fastening rail, so that the two operating chains actuating the sprockets run parallel to the two long sides of the fastening rail . An arrangement of the two operating chains is possible in such a way that the chain strands of each operating chain lie one above the other and are deflected accordingly at the end of the fastening rail, although, according to a further embodiment, the chain strands of each operating chain run next to one another and also on the Umlauf end of the mounting rail, so that then the two chains with their chain strands lie one above the other in two levels.

The winding shafts are set in rotation by means of the operating chains and by their engagement in the chain wheels of the winding shafts in the bobbin cases, and depending on the direction of rotation of the winding shafts, the pull cords attached to the lower edge of the curtain are rolled up or unrolled.

Because of this configuration, it is possible for a curtain of the type described in the introduction not only hang and gather, but also fan-gather and relax.

The invention further provides an embodiment according to which the rear of the curtain has at least one U-shaped pull cord guided by two guide rings fastened to the curtain adjacent to its upper edge with two ends running transversely to the winding shaft and with their free ends at the lower end Edge edge of the curtain fastened cord sections and having a cord connecting section formed between the two guide rings and running parallel to the take-up shaft and connecting the pull cord sections, and the take-up shaft on its circumference has at least one circumferential area in the area of the pull cord connection section carries cam-shaped or hook-shaped pull cord drivers which, when the curtain is unraveled, are out of engagement with the pull cord connecting section and which are used to wind the pull cords onto the take-up shaft during the curtain winding process with the winding going round elwelle grips the pull cord connecting sections.

With a shirred curtain designed in this way, it is possible for the first time to release and establish an operative connection between the drawstrings of the curtain and the winding shaft, without the need for complex technology. In the unraveled state of the curtain, the pull cord driver on the take-up shaft is out of engagement with the pull cord guided in a U-shape on the back of the curtain, while the pull cord with its in the area of the opening already starts at the beginning of the orbital movement of the take-up shaft of the pull cord driver - 97/17876

seizes the winding shaft lying section, so that with a further rotation of the winding shaft, the pull cord gripped by the pull cord driver is wound onto the winding shaft, the curtain being gathered at the same time. The operative connection between the pull cord and its take-up shaft is controlled by the direction and movement of the take-up shaft, so that the curtain can be easily removed from the fastening rail when the curtain is unraveled. The detachable fastening of the curtain to the fastening rail is advantageously carried out via a Velcro-shaped connection, so that not only the detachment of the curtain from the fastening rail is effortless and can be carried out by anyone. Due to the inventive design of the shirring curtain, the pull cords no longer need to be individually detached from the winding shaft or connected to it. Only a U-shaped guidance of the pull cords on the curtain and a pull cord driver on the winding shaft are sufficient to provide such an advantageous gathering curtain to the owners of apartments or the like. to provide.

If the curtain of the venetian blind has a larger width, a larger number of pull cords is also required. However, it is always essential that each pull cord is U-shaped on the back of the curtain and that a number of guide rings is attached to the curtain in such a way that pull cord sections running parallel to the winding shaft are formed so that they for the winding process of the pull cords can be gripped by the driver on the winding shaft. The arrangement of the guide rings on the curtain takes place in the region of the winding shaft such that the Draw cord sections running parallel to the winding shaft lie in the circumferential range of motion of the pull cord driver when the pull cord driver is set in motion by the revolving movement of the winding shaft. Each pull cord is formed by a pair of pull cord consisting of pull cord sections running transversely to the winding shaft and a pull cord connecting section connecting these pull cord sections in the region of the winding shaft. If several U-shaped pull cords are provided on the back of the curtain, then their arrangement is such that the pull cord sections of different lengths formed between the guide rings on the curtain and parallel to the winding shaft are so close together that all of these draw cord sections are gripped by the pull cord driver can be.

Advantageous embodiments of the invention are characterized in the subclaims.

The fastening rail 540 of the roman blind 100 'is used to fasten it to a ceiling or a wall in a window area. The two ends 540a, 540b of the rod-shaped fastening rail 540 carry bearings 541, 541 'for a winding shaft 550 for the pull cords 520, 620.729 (FIG. 25).

The winding shaft 550 for the pull cords is formed as an cylindrical shaft body and consists of a hollow shaft or a solid shaft. At the end regions 550a, 550b, the winding shaft 550 carries bearing pins which are in the Bearings 541, 541 'of the fastening rail 540 are mounted, so that the winding shaft 550 can be rotated about its shaft axis 556 in the direction X, X1. The winding shaft 550 is actuated via a drive 551 by means of a control cord or chain 555, it being also possible to use electromotive drives which are guided over a drum 552 of the drive 551 arranged at the end 550a of the winding shaft 550. By pulling one or the other strand 555a, 555b of the service chain 555, the winding shaft 550 is set in rotation, either in one direction or in the other direction.

The winding shaft 550 carries on its circumference at least one cam or hook-shaped pull cord driver 560 with its circumferential area in the area of the pull cord connection sections 524 or the pull cord connection sections 624, 724, which, when the curtain 510 is in a draped state, out of engagement with the pull cord connection section or sections 524, 624, 724 and which, for winding up the pull cords 520, 620, 720 or their pull cord sections 522, 523 and 622, 623 and 722, 72 on the take-up shaft 550 during the curtain winding process with the revolving take-up shaft 550, grips the pull-cord connecting sections 524, 624, 724.

As FIG. 23 shows, the guide rings 530, 531 and 630, 631 and 730, 731 are attached to the curtain 510 for the pull cords 520, 620, 720 on both sides of the longitudinal center line 511 of the curtain 510 (FIG. 24). In this way, three guide rings, namely 530,630,730 and 531,631,731, are attached to the curtain 510 on each side of the longitudinal center line 511, the distances between the two guide rings 530,531 for the pull cord 520, the guide rings 630,631 for the pull cord 620 and the guide rings 730,731 for the pull cord 720 from the longitudinal center line 511 of the curtain 510 are the same.

The pull cord driver 560 can have the most diverse configurations. According to an embodiment according to FIGS. 30A, 30B and 30C, the pull cord driver is

560 consists of a plug-like shaped body 561 which, according to FIG. 30A, is provided with a hook section 562 or, corresponding to FIG. 30B, with two oppositely directed hook-shaped sections 562, 562 '. The embodiment according to FIG. 30C also consists of a plug-like shaped body 561 which carries a driver cam 563, this driver cam 563 having a button-like widening 563a at its free end in order to be able to act as driver. There is also the possibility of the plug-like shaped body

561 to be provided with a screw-shaped molded body, the head-like configuration of the screw-shaped molded body then having the function of a driver. This configuration of the pull cord driver 560 has the advantage that the pull cords for the winding process are securely gripped on the one hand and are secured against slipping during the winding process and on the other hand an effortless unhooking from the pull cords is ensured.

Insofar as the pull cord drivers 560 have a plug-like shaped body 561, the winding shaft 550 is provided on its circumference with a number of recesses or openings in which these plug-like shaped bodies 561 of the pull cord drivers 560 are inserted. If these plug-like shaped bodies 561 consist of a resilient, elastic plastic, the pull cord Driver 560 held in the recesses or through-bores in the wall of the shaft body of the winding shaft 550 by means of a press or clamp fit. Additional connection options are provided insofar as this type of pull cord driver 560 is then still secured by adhesive connections. The carriers 560 in the embodiments according to FIGS. 30A, 30B and 30C can consist of plastics, metallic materials or other suitable materials.

However, it is also possible to provide the shaft body of the winding shaft 550 with a pull cord driver 560, which is formed on the outer circumference of the winding shaft 550 in such a way that a hook-shaped configuration results. In this embodiment, the pull cord driver 560 is then made of the same material as that of the winding shaft 550. 31 also shows a further embodiment insofar as a driver screw 565 is screwed into the shaft body of the winding shaft 550 and has the same function as the cam or hook-shaped pull cord driver 560. There is also the possibility of pull cord pull 560 to be fastened to the winding shaft 550 by means of a screw connection. Embodiments of pull cord drivers 560 other than those shown in the drawing and described above can also be used. It is essential that the pull cord driver 560 is fastened to the outer circumference of the winding shaft 550 and has a configuration on the basis of which the pull cord driver 560 detects the pull cords for the winding process and can also release them when the curtain 510 is removed from the fastening rail 540 to be removed or released. The venetian blind 100 'is used according to FIGS. 26 to 29 as follows:

In the draped state of the curtain 510, the pull cord driver 560 is out of the engaged position, i.e. the pull cord driver 560 stands on the side facing away from the curtain 510 and is disengaged from the pull cord connecting sections 524, 624, 724 in area A (FIG. 26). If the winding shaft 550 is now rotated in the direction of the arrow X2 by means of the operating chain 555, the pull cord driver 560 pivots from the position B1 to the position B2 and grips the pull cord connection sections 524, 624, 724 in the pull cord section area A (FIG. 27). The pull cord driver 560 is hook-shaped in such a way that the pull cord driver engages the pull cord connection sections 524, 624, 724 from above. Until the pull cord driver 560 engages in these pull cord connecting sections of the pull cords 520, 620, 720, the curtain 510 still assumes its unraveled position. If the winding shaft 550 is rotated further, the pull cord driver 560 takes the pull cord connecting sections 524, 624, 724 of the pull cords 520, 620, 720 with (FIG. 28), the pull cords 520, 620, 720 being wound onto the winding shaft 550 while the winding shaft 550 is rotated further this winding process, the curtain 510 is gathered (FIG. 29).

When the gathering process for the curtain 510 has ended, the gathering curtain 100 'assumes the position shown in FIG. 40; the pull cord driver 560 is then still in engagement or in operative connection with the pull cords 520, 620, 720 in the area of their pull cord connecting sections 524, 624, 724. If the direction of rotation of the winding shaft 550 is changed and if it is rotated in the direction of the arrow X3, then the pull cords 520, 620, 720 are unwound from the winding shaft 550 while simultaneously performing the de-entangling process for the curtain 510, so that when the disentangling process for the curtain ends 22, ie the curtain 510 assumes the stretched position shown in FIG. 22, then the pull cord driver 560 is brought out of the engagement area to the pull cord connecting sections 524,624,724 of the pull cord 520,620,720, that is to say the pull cord driver is no longer in operative connection with the pull cord Curtain 510 can be separated from its fastening rail 540 of the roman blind 100 ', ie it can be detached.

In a configuration of the gathering curtain 100 'according to FIG. 23, the pull cord driver 560 is centered on the winding shaft 550, i.e. that is, in the area of the longitudinal center line 11 of the curtain 510, because in this area the arrangement of the guide rings 530, 531 and 630, 631 and 730, 731 in the area around the pull cord driver 560 means that the pull cord sections of the pull cords to be gripped by it 520,620,720.

In the winding shaft 550 for a shirring curtain 550 described above and shown schematically in FIG. 32, three pull cords 520, 620, 720 in the form of U-shaped pull cord pairs 521, 621, 721 are provided, which are guided through paired guide rings 530, 531 and 630, 631 and 730, 731 that in each case three pull cord connection sections 524, 624, 724 running parallel to one another and to the longitudinal axis of the take-up shaft 550 can be grasped together by a single pull cord driver 560 fastened in the center of the take-up shaft 550. In contrast, according to a further embodiment according to FIG. 33, more than one pull cord driver 560 can also be provided, the number of pull cord drivers depending on the number of guide rings 530 ', 531' and 630 'which are guided in a U-shape and are combined by pairs. , 631 'and 730', 731 'pull cord pairs 521', 621 ', 721' of three pull cords 520 ', 620', 720 'direction. In this embodiment, the individual U-shaped pull cord pairs 521 ', 621', 721 'are arranged side by side, so that the draw cord connection sections 524', 624 ', 724' running parallel to the longitudinal axis of the winding shaft 550 are not as in 32 are superimposed in the central region in order to be able to be grasped by a single pull cord driver 560, but rather lie in series one behind the other so that in order to pull the pull cord connection sections 524 ', 624', 724 ' to be able to grasp, three pull cord drivers 560, 560 ', 560 "are provided, of which each pull cord driver is arranged centrally to the respective pull cord connecting section 524', 624 ', 724' on the take-up shaft 550. The minimum number of U-shaped pull cord pairs for the curtain 510 should be two.

The pull cord driver 560 can be fixedly or also releasably connected to the winding shaft 550. The embodiment according to FIG. 25 is particularly advantageous in that the winding shaft 550 is provided on its circumference with a longitudinal slot 580, for example in the form of a guide groove, which receives the slide-shaped pull cord driver 560 and ensures a longitudinal displacement, which is achieved by the arrows Z is indicated. Because of this configuration, it is possible to adapt the winding shaft 550 to the respective requirement to arrange a corresponding and required number of pull cord drivers 560, the spacing of the pull cord drivers 560 being able to be adapted to the pull cord sections to be detected due to the displaceability. There is also the possibility, in addition to a central arrangement of a single pull cord driver 560 on the winding shaft 550, of being able to carry out an off-center arrangement of the pull cord driver if this should become necessary.

In addition to the use of a single take-up shaft 550, there is also the possibility of arranging two take-up shafts at the end regions of the fastening rail 540, which are designed as short shafts and which can be provided with pull cord drivers 560 in the same way as the take-up shaft 550. The length of the two winding shafts can be chosen arbitrarily. It will essentially depend on the width of the curtain 510. Each of the two winding shafts is then provided with an operating cord or chain 555. Controllable electromotive drives can also be operatively connected to the winding shafts.

Through the use of two short-dimensioned winding shafts, it is possible with simple technology and without great technical effort to gather and / or fan the curtain. The use of a venetian blind designed in this way is therefore also possible in the case of gable windows and horizontal round arches and wherever a winding shaft which is long enough to match the width of the curtain cannot be fitted.
