Guide device for folding curtains

The innovation concerns a guide device for folding curtains according to the generic term of claim 1. The purpose of such guide devices is to shade sloping roofs, sun roofs, shed windows, winter gardens and

α uSryxBiCiiSn. ca uönuSlt älüh frierböi UiTi öifi Falti vi5x ^- nängsy seem, which is used for both curved and straight systems. So far it is known to use a so-called cable pull drive for the guide rails arranged parallel and at a distance from one another, whereby the cable pull runs through corresponding channels in the guide rail and is connected to a leader, which in turn is connected to the lowest connecting rod of the curtain.

For each guide rail, a revolving traction cable is provided, which is connected to the forerunner. The disadvantage of this drive system is the relatively expensive design with a cable pull and a corresponding electric motor drive.

It is also known to use a circulating traction cable for both guide rails together, but this also involves a high level of mechanical effort and high costs for the drive.

The previously known folding curtain systems also suffered from the disadvantage that due to different length expansions of the pull rope over a longer period of time, the connecting rod, which was held in the guide groove of the guide rail, became jammed, which led to a deterioration

&igr;&igr; · ·

the running characteristics of the folding curtain system*

The innovation is based on the task of developing the folding curtain system mentioned at the beginning in such a way that even with large folding curtain widths, a jam-free guide can be achieved with a simple drive.

To achieve the stated objective, the innovation is characterized in that, for a tilt-free displacement drive of the connecting rods along the guide rails, the respective connecting link between the connecting rod and the sliding element that can be moved in the running channel is designed to be articulated and adjustable at least in the direction of the longitudinal axis of the connecting rod, and that at least the connecting rod that is at the bottom of the curtain is acted upon by a displacement drive from both sides of the connecting link ₈

The feature of this innovation is the fact that there is an articulated connection between the connecting rod and the associated sliding element in the guide rail. This means that the connecting rods have a relatively large bearing clearance in the area where they are attached to the sliding element. Such an articulated connection can be created in several ways.

A first embodiment provides that the sliding element is connected to an eyelet into which a hook engages, which is connected to the connecting rod. This hook-eye connection according to claim 2 provides the desired bearing play.

An even larger bearing clearance results from the object of the

Claim 3, if the glider connected to the

A ring is first passed through the eyelet, through which the hook of the holder first grips.

•r

With such a large bearing clearance, it is now possible to compensate for differences in distance between the opposing guide rails, which could not be compensated for with the previously known folding curtain systems.

In particular, if such guide rails are mounted on the opposing rafters of a roof, there is no guarantee that the rafters will be evenly spaced from one another over their entire length.

Previously, it was necessary to attach the guide rails to the roof rafters using shims to ensure a uniform distance between the guide rails over their entire length.

This is no longer necessary according to the present invention, because the articulated connection between the sliding element guided in the running channel and the associated connecting rod, which carries the curtain, prevents the guide rods from jamming or tilting during the longitudinal displacement, so that even with such differences in distance between the guide rails, the entire folding curtain system runs smoothly and without tilting.

In addition to the formation of a hook-eye connection between the sliding element in the guide rail and the associated holder, which is connected to one end of a connecting rod, there are other possibilities for producing the stressed joint connection.

• according to

Another possibility is a rubber-elastic connection between the holder and the associated sliding element, which also compensates for a corresponding difference in distance between the opposing guide rails within a range of a few millimeters.

In addition to the use of a hook-eye connection and a rubber-elastic connection, there is also the possibility of forming a hinge-like connection, whereby using a known single-joint hinge, the hinge axis runs parallel to the longitudinal axis of the respective guide rail, so that an adjustment play of this hinge perpendicular to the longitudinal axis of the guide rail is possible.

To ensure that the entire folding curtain system runs smoothly and without jamming, a corresponding sliding drive is also required, which ensures that the connecting rods are driven exactly synchronously and evenly at their two opposite ends during upward movement in order to avoid jamming from the outset.

Here, claim 1 provides that the displacement drive is evenly positioned at the ends of the respective connecting rod, thereby ensuring a synchronous drive of the connecting rod along the guide rail.

This avoids a cable pull system in which the left side and the right side of the respective connecting rod are driven by their own cable and the present invention provides that a single displacement drive acts on both sides of the connecting rod.

i ■ ·

In a first embodiment of such a sliding drive, a cost-effective manually movable drive is provided, which consists of a carriage that can be moved longitudinally in the guide rails and to which the curtain is attached.

The bottom end of the curtain is attached to the bottom side of the carriage using Velcro, so that the carriage is completely covered by the curtain at the bottom and is no longer visible from the visible side.

The carriage can now be moved manually along the guide rails, which results in particularly easy and jam-free running. _t

After the carriage rests against the curtain's lowest sliding rod over its entire width, this sliding rod also rests evenly against the carriage and is thus guided without jamming.

As soon as the carriage is pushed upwards, it first takes the curtain's lowest connecting rod with it and this in turn, after a certain distance of displacement, takes all the other connecting rods with it one after the other, so that when pushed up, the folding curtain is pushed together in the upper part of the guide rails and all the connecting rods lie close together.

The folding curtain system can be pulled out either manually by applying a corresponding pulling force to the carriage; however, it can also be done by gravity, namely when the guide rails form such an angle to the horizontal that the carriage rolls downwards in the guide rails due to its weight and thus pulls the folding curtain with all its connecting rods

takes with him.

In order to be able to lock the carriage in any position between the guide rails, a locking device is provided that can be manually locked and released.

In order to ensure that the carriage also runs without jamming in the area of the opposing guide rails, it is intended that sliding elements are arranged in the carriage so that they can be moved in a direction perpendicular to the longitudinal axis of the guide rail, so that the carriage also compensates for the corresponding differences in distance between the opposing guide rails and runs without jamming or jamming.

In addition to the manual drive of the folding curtain system with the described carriage, a further development of the present innovation is to instead use a lifting system with a lifting belt and a motor, whereby the motor drives winding spools on which the lifting belt is wound.

The subject matter of the present innovation arises not only from the subject matter of the individual protection claims, but also from the combination of the individual protection claims with one another. All information and features disclosed in the documents, in particular the spatial design shown in the drawings, are claimed as essential to the invention insofar as they are new individually or in combination compared to the prior art.

In the following, the innovation is explained in more detail with the help of drawings showing several implementation options.

In Figure 1, the folding curtain system according to the invention is shown in a first embodiment, in the area of two roof beams 1 that are parallel to one another and arranged at a distance from one another, a guide rail 2 is attached to the inside of each roof beam with fastening screws that are not shown in detail on the roof beam 1. Each guide rail has an approximately C-shaped profile with a longitudinally running channel 3, which is interrupted on one side by a longitudinally running guide groove 4. j

The profile of the guide rail is not essential to the inventionj because all known profiles for guide rails can be used which have one or more guide channels and at least one guide groove cut into them.

In the following, the fastening of the curtain using connecting rods in the guide rails is explained first, because this fastening remains the same for all subsequent embodiments, while the sliding drive of the entire curtain is carried out either with a carriage or by an electric motor.

The curtain 18 extends in such a width that the underside of the respective guide rail 2 is covered; i.e. it has a width that almost fills the distance between the roof beams 1.

··· · tu &igr;

&iacgr;&ogr;) -

The curtain 18 can be provided with so-called pockets 19.

Such a pocket is sewn onto the curtain and is designed like a tunnel, with a connecting rod 25, 55 being pushed through the resulting cavity.

The lowest connecting rod of the curtain is given the reference number 55 because this connecting rod has special functions, while the other connecting rods are given the reference number Z5.

Instead of making a pocket 19 by sewing on another piece of fabric, a fastening according to Figure 18 between the connecting rod and the curtain is also provided. This fastening is explained in more detail at the end of the description.

Each connecting rod 25,55 extends through the pocket 19 over its entire length and rests against the underside of the guide rail 2 so that it is covered by the curtain 18 from the visible side.

The connection between the connecting rod 25, 55 and a slider 20 slidably guided in the guide groove 4 of the respective guide rail 2 is made in a first embodiment according to Figure 1 in such a way that an eyelet 21 is formed on the slider 20, through which the hook 23 of a holder 22 engages, which in turn is attached to the connecting rod 25, 55 by clipping on.

The holder 22 is made of a plastic profile and consists, as shown in Figures 2 and 3, of a round profile 54 which has a slot 57 at the bottom with such a width that the round profile

- 11 -

54 can be clipped onto the* smaller diameter connecting rod 25 as shown in Figure 3.

Figure 3 does not show that the connecting rod 25 is at least partially covered by the curtain 18, as shown in Figure 18, so that this measure eliminates the need to sew pockets 19 into the curtain 18. By clipping the round profile 54 onto the connecting rod 25 covered by the curtain 18, a firm connection is created between the curtain and the connecting rod, without the need to sew pockets in.

Likewise, according to Figure 1, another connection mechanism is possible, in which the connecting rod is simply pushed through loops 59 attached to the back of the curtain 18, as is indicated in Figure 1.

Figure 2 shows an embodiment modified from Figure 1 in the area of detail II, because it can be seen there that a ring 56 is interposed as an articulated connection between the slider 20 and the hook 23 of the holder 22 in order to give the connecting rod 25 a greater adjustment play in the direction of its longitudinal axis.

The articulated connection between the slider 20 and the holder 22 is intended to give each connecting rod an adjustment play in the direction of its longitudinal axis in order to compensate for distance differences between the opposing guide rails so that each connecting rod 25 can be moved with its slider 20 in the guide rail 2 in the directions of arrows 16, 17 without jamming.

A carriage 5 is provided as a sliding drive for the folding curtain system shown in Figure 1, which in the present embodiment consists of two parallel profiles 6, 7 spaced apart from one another (see Figure 15).

The two profiles are connected to each other by corresponding connecting struts.

According to Figure 14, each profile 6, 7 has groove channels 42 that are parallel to one another and arranged at a mutual distance from one another, with a sliding element 26 being inserted into each groove channel and being held in an axially adjustable manner in the groove channel 42.

The shape of each sliding element can be seen from Figures 12 to 15.

According to Figures 12 and 13, each sliding element 26 consists of a plastic body which has cross-shaped ribs 41, with an outer flange 40 of enlarged diameter being formed on the front end of these ribs and an inner flange 39 being formed at a distance therefrom with the interposition of a connecting piece 60 of reduced diameter.

According to Figures 14 and 15, each sliding element 26 with its cross-shaped ribs 41 is inserted into the respective associated slot 42 of the carriage in the area of the profiles 6,7.

According to Figure 14, the ribs 41 are positioned such that the sliding element is axially adjustable in the direction of the arrows 43, 14 (Figure 15) in the groove channel 42, but that the sliding element 26 is not rotatably mounted in the groove channel 42.

The arrangement of these sliding elements 26, which are held so as to be axially displaceable in the carriage 5 in the arrow directions 43, 44, also results in the carriage 5 running smoothly and without jamming in the arrow directions 16, 17.

The locking device of the carriage 5 is now described in more detail below.

The locking device, which is described in more detail with reference to Figures 1, 4 to 11, serves to lock the carriage in any intermediate position in the area of its displacement in the arrow direction 16, 17.

For this purpose, the profile 6 has a longitudinal slot 61 in the area of its front end face, as is also shown in Figure 14 in the other profile 7 in the area of the groove channels 42.

An actuating shaft 13 is inserted into the groove channel 42 and is mounted there so that it can rotate easily. The actuating shaft 13 is connected in a rotationally fixed manner to an actuating plate 9 according to Figure 4 and Figure 5, which has an engagement opening 10 at its front end.

The engagement opening 10 serves to engage a hook 12 which is connected to an actuating rod 11. This allows the actuating plate 9 to be pivoted in the arrow directions 14, 15. Figure 4 shows the front view of the carriage with an actuating plate pivoted upwards in the arrow direction 14, which leads to the carriage being unlocked, while Figure 5 shows an actuating plate 9 pivoted downwards in the arrow direction 15.

- 14 , which leads to a locking of the carriage.

The actuating shaft 13 is designed as a multi-edge shaft according to Figures 7, 10 and 11 in order to ensure the required rotationally fixed connection with the actuating plate 9.

According to Figures 4, 6 and 7, the actuating shaft 13 is inserted at its opposite ends into the central bore 62 of a braking part, which is provided with corresponding internal ribs, so that this braking part 30 is also connected in a rotationally fixed manner to the actuating shaft 13.

According to Figures 6 and 7, each brake part consists of a cylindrical base body with the ribbed central bore 62 arranged therein. At one end of the plastic body, a contact plate 33 is formed, which merges into a connecting piece of reduced diameter, whereby the connecting piece in turn opens into a brake plate 31 of enlarged diameter.

According to Figures 4 and 5, the contact plate 33 rests on the outside of the guide rail 2, while the connecting piece reaches through the guide groove 4 and the brake plate 31 projects into the running channel 3 and can be freely moved or clamped there.

The brake plate 31 has the diamond shape shown in Figure 7, whereby when the actuating shaft is rotated, for example in the direction of arrow 36, the diamond-shaped brake plate is also rotated and thus the upper and lower brake surfaces 34 are rotated apart in the direction of arrow 37, whereby these brake surfaces are positioned on the inside 38' of the running channel 3 of the respective guide rail according to Figures 4 and 5.

" 15=

invest,

Figure 5 shows the locked position of the brake plate

31'.

To prevent the brake plate 31 from falling off the actuating shaft, it is secured to the actuating shaft 13 using a screw 35*

Figures 8 to 11 show the actuating plate 9 in its unlocked position (Figures 8 and 10), while Figures 9 and 11 show the actuating plate in its locked position.

If, with the aid of the actuating rod 1 shown in Figure 1, the hook λ2 is inserted into the engagement opening 10 of the actuating plate 9 and the actuating rod 11 is moved in the direction of the arrow IS, then, according to Figure 10, the actuating plate 9 is pivoted in the direction of the arrow 36 and thus pivots the actuating shaft 13 in the same way, whereby the braking surfaces 34 of the braking plate 31 rest in the arrow directions 37 (Figure 7) on the associated inner sides 38 of the running channel 3 (see Figure 4).

This means that the carriage 5 can be locked in any position as shown in Figure 1 during its sliding movement in the directions of the arrows 16,17.

The curtain 18 then forms, depending on the sliding position of the carriage, more or less bulbous or cloudy hanging lower surfaces, which tighten into straight surfaces in the end position of the carriage 5.

The right part of Figure 14 shows the top view of the

Figure 15 shows the top view of the braking part, which is installed in the carriage at the front part of profile 6.

Since each guide rail 2 is assigned a braking part 30, which is actuated by a common actuating shaft 13, there is no tilting even when the carriage is locked and thus the carriage is always guided perfectly over the entire length of the guide rails 2, whereby it is important that the actuating shaft 13, which is provided with corresponding ribs, engages in an axially adjustable manner in the center bore 62 'of the respective braking part 30 according to Figure 6, so that the braking part itself - just like the sliding elements 26 - is held in the respective groove channel of the profile 6 so that it can be moved in the directions of the arrows 43, 44 and thus any possible difference in distance between the opposing guide rails 2 is compensated.

Figure 16 shows a modification of a folding curtain system compared to that shown in Figure 1. It should be emphasized here that both the electric motor drive shown in Figure 16 and the carriage for the manual sliding drive can be present; however, it is also sufficient to provide only a manual sliding drive according to Figure 1 or only an electric motor drive of the lowest connecting bar 55 according to Figure 16.

For this purpose, each holder 22 according to Figures 2 and 16 has an eyelet 24 on its upper side through which the lifting belt 49 of a drive is pulled.

-17 ' -

The lifting strap 49 is hereby firmly connected to the eyelet 24 of the connecting rod 55 at the bottom of the curtain in a manner not shown in detail and is otherwise slidably pulled through all the other eyelets 24 of the holders 22 above it.

The upper end of the lifting belt is taken up by a winding spool 47, which is connected in a rotationally fixed manner to a winding shaft 45.

The winding shaft is driven by a motor 46 in the direction of rotation 48, whereby when the winding shaft 45 is driven, for example in an anti-clockwise direction, the two parallel lifting belts 49 are wound onto the winding spool 47 in precise synchronization and due to the fixed connection between the eyelet 24 of the lowest connecting rod 55 of the curtain and the lifting belt 49, the connecting rod 55 is thus pulled upwards in the direction of arrow 16 and takes all the other connecting rods 25 with it on its way, whereby the lifting belt 49 slides easily through the eyelets 24 of the other connecting rods 25.

Instead of a lifting tape 49, a lifting cord can of course also be used; the use of a lifting tape has advantages, however, because the lifting tape is wound up in an orderly manner on the winding reel 47 in superimposed windings, whereas with a lifting cord, a disorderly winding with slanted windings, which can lead to an unintentional shortening of the winding cord on one side compared to the winding cord on the other side.

Any misalignment of the elevator belt in relation to the guide rail is compensated for by the fact that the respective winding spool 47 is connected to the winding shaft 45 in a rotationally fixed manner, but is axially displaceable in the direction of the winding shaft 45.

'< · > IIII

If the winding shaft 45 is driven clockwise in the direction of rotation 48, the lifting belts 49 are unwound from the winding spools 47 and the connecting rods slide downwards in the opposite direction to the arrow 16, whereby the sliders 20 are displaced under the weight of the curtain and the associated connecting rods in the guide groove 4 of the respective guide rail 2.

Figure 17 shows, in addition to the embodiment according to Figure 1 or Figure 16, that the distance between individual connecting rods 25 can be fixedly adjusted via a ball chain 50.

Such a ball chain can be used both in the embodiment according to Figure 1 and in the embodiment according to Figure 16.

In order to adjust the distance 58 between adjacent connecting rods 25, 55, the ball chain 50 is used, which is attached to the holder 22 in a clamping block 58 according to Figure 18.

According to Figure 18, the clamping block 58 consists of a cube-shaped formation in the area of the straight part of the hook 23, wherein a clamping opening 22 is provided on the front side of the clamping block, which can be pressed apart by a spring, the required spring effect being achieved by a slot 53 passing through the clamping opening 52.

The ball chain can then be easily detachably connected to the holder 22 by pressing a ball into the clamping opening 52 and thus the distance 58 between adjacent connecting rods 25, 55 can be easily adjusted and changed.
