BACKGROUND OF THE INVENTION The present invention relates to a device for hanging blinds with blinds or the like, comprising at least one open guide wire profile, a plurality of carrier members, each having a gear transmission unit and a guide member movable along the guide in a guide profile. a control bar pivotally disposed parallel to its longitudinal axis and actuated in each case by a gear of the transmission unit, rotatable axles with a ribbon-bearing pivoting member which is connected to another gear and is mounted on a carrier member, each of which is supported by a carrier member; is slidably guided in the guide member of the adjacent carrier member.

The structure described above is often used for shading openings, especially window openings, for which purpose the strip lamellae are regularly arranged in front of the surface of the opening and are rotated about their vertical axes to a greater or lesser extent. The shifting and rotating movements can be performed independently.

The strip lamellae are automatically aligned in front of the aperture surface by moving a given carrier member at a given distance from another carrier member, the length of the gap being determined by the stop on the spacer bar. As the carrier member is moved further, it also carries with it the subsequent carrier member, which movement is again determined by the subsequent spacer bar.

The disadvantage of the known structure is that the conductive profile in which the support members are guided is relatively high, which is not advantageous for the aesthetic appearance of the entire curtain. In each case, the stacked spacer strips require a significant thickness which is added to the height of the support members.

SUMMARY OF THE INVENTION It is an object of the present invention to overcome the above disadvantage and to provide a guide profile that is aesthetically acceptable, small in size and therefore easily combined with other profiles for other applications.

The suspension device according to the invention, which solves the object of the invention, is characterized in that the spacer strip is fixed to the side of the support member so that the panel of the spacer strip is oriented vertically.

As a result of the vertical positioning of the spacer plate, the series of spaced spacers extend not in height but in width, whereby thinner strips can be used due to the better self-holding property of the spacer strip, which also reduces the thickness of the entire series. Standing spacer • · ·

A further advantage of the 4 slats is that the guide rail of the louvre curtain can be arranged at an angle other than the horizontal, while the tension members are no less correctly positioned by the spacers without the risk of breakage.

According to the invention, it is expedient that the guide profile formed as a rectangular tube has on each side wall a continuous inwardly extending rib between the lower wall and the upper wall of the guide profile, on the one hand forms.

In the latter case, the distance between the rib and the upper or lower wall of the guide profile is at least equal to the diameter of the running roller mounted on the support member.

The overall height of the guide profile substantially corresponds to the height of the support members, so that the guide profile can include the support members in a substantially tight fit.

According to a further preferred embodiment of the device according to the invention at least one guide groove is formed in the upper wall of the guide profile, which receives the ends of the arms connected to the support members. These arms also serve to maintain the correct position of the support member in the guide profile so that the support members are not trapped, even under uneven loading on the tape lamella. According to a further preferred embodiment of the invention ···· ····

a grooved side wall of the guide profile adjacent to the support member wire provides space for additional profiles.

The foregoing and further features of the invention will be described in more detail with reference to the accompanying drawings, in which: FIG.

In the drawing, Fig. 1 is a perspective top view of a suspension structure of a blind according to the invention, with the guide profile partially broken away for better clarity, and Fig. 2 is a perspective view of a detail of the structure shown in Fig. 1, namely Figure 3 shows another detail of the structure shown in Figure 1, in perspective view corresponding to Figure 2, Figure 4 showing an additional profile

Figure 5 shows a cross-sectional view of the suspension structure of Figure 1, Figure 5 illustrates a possible embodiment of the support member, in a view corresponding to Figure 2;

Figures 6 and 7 are perspective views of one embodiment of a gear unit with a sliding friction clutch sliding under load, respectively.

As shown in Fig. 1, the suspension device according to the invention has a hollow guide profile 1 which is preferably tubular and has a longitudinal slot 2 in its lower wall through which the suspension members 3 of each strip section 4 can be moved. The guide profile 1 is fixed to the ceiling or other fixed position in a manner not shown in the drawing, such that the longitudinal slot 2 extends on the underside of the guide profile 1.

In the guide profile 1, support members 5 are provided, each of which is provided on both sides with a running roller 7. This running roller 7 can be rotated freely on a pin fixed on the support member 5. Preferably, the support member 5 provided with a roller bearing pin 7 is made of a suitable material, such as plastic, in one piece.

The carrier member 5 comprises a gear unit 8 comprising a worm wheel 9 and a gear wheel 10. The worm wheel 9 has a central opening through which a guide bar 11 is passed which extends parallel to the longitudinal axis of the guide profile 1. The control rod is not completely circular, so that when the control rod is rotated, the worm wheel 9 can turn with it. At the same time, the worm wheel 9 rotates the gear wheel 10, the hollow core of which is fitted with the shaft 12 of the suspension member.

Each support member 5 is successively provided with a spacer member formed as a strip of a suitable material and mounted in a recess 13 formed on one side of the support member, fixed at one end thereof in a vertical position with its face. The recess 13 is provided with an upwardly projecting deflection 14 spaced from the bottom of the recess 13 so that not only one end of the spacer strip 66 is arranged between the deflection projection 14 and the bottom of the recess 13, but also the spacer strip 66 of an adjacent carrier member 5. 1, as shown in Figure 1. This other end of the spacer bar 66 is provided with a stop 18 which prevents this other end from slipping out of the recess 13 of the adjacent carrier member 5.

According to one feature of the invention, the guide profile 1 is provided with ribs 20 on both sides, which are parallel to the upper wall 24 and the lower wall 21 of the guide profile 1 and which, as shown in FIG. forming a chamber 23 extending to the edge of the trajectory of the carrier members 5. This

V ··· · · ««

A chamber 23 serves for receiving the spaced-apart slats 66 when the support members 5 are pulled together. The rib 20 also serves to support the running rollers 7 of the support members 5, since together with the upper wall 24 of the guide profile 1, this rib 20 forms a rail-like conductor, as shown in FIG.

The upper wall 24 is provided with outwardly extending guide grooves 25 in which the ends 26 of the arms 27 projecting from the carrier members 5 are slidably disposed. These arms 27 serve to prevent the support members 5 from tipping over and sliding out of the guide profile 1 and thus facilitate the sliding of the support members 5 along the guide bar 11 and the sliding bars 66 in the recess 13. If necessary, the lever 27 'having a function similar to the arm 27 may also be arranged on the lower surface of the carrier member 5 as shown in FIG.

The carrier members 5 can slide within the guide profile 1 in the direction of the arrow P1 by means of a control device 30 which is designed as a draw cord. Figure 1 shows, on the left, two parts of the tensioning cord 30, which is guided around a pivoting wheel and retracted at the end of the guide profile 1 (not shown). A portion of the drawstring 30 is secured to the last support member 5 in the row, which is also not shown. The last 5 carrier members can thus be moved back and forth through the strands of the pull cord 30, whereby the last 5 carrier members pull the next 5 • · · in front of them.

- a carrier member 9 through spacers 66 which in each case provide a maximum distance between the carrier members 5. When the pulling cord 30 is pulled in the opposite direction, the last carrier 5 is pushed forward in front of the carrier members 5 until they lie on top of each other.

The draw cord 30 can be pulled through a double guide roll 31 provided in an injection molded end member 32, while the strands of the draw cord 30 can be moved through the openings 33 of each carrier member 5.

The end member 32 also forms an end bearing for the control bar 11, in which the control bar 11 is freely rotatable. At the end of the control rod 11 projecting from the bearing, a gear 34 is provided which engages with a gear 35 of a drive wheel 36. The drive wheel 36 is provided with a peripheral ring 37 having a housing for receiving the balls of the chain 38, so that when the branch of the chain 38 is pulled, the peripheral ring 37 is rotated in the direction of arrow P2 so that the gear 34 is also properly, via the 35 gears. The gear 34 rotates the control rod 11, and thereby all the worm wheels 9 in the carrier members 5.

As shown in Fig. 3, the end member 32, like the carrier members 5, is formed as a single injection molded piece having various components.

- 10 freely rotatable. For example, the guide roller 31 of the drawstring 30 is provided with a shaft stub 40 at each end which fits into a recess formed in the wall of the end member 32. The guide wire 30 is guided by a cap-like insert 41 with arcuate cutouts 42 which can be inserted into the injection molded end 32 in the direction of arrow P4. The disc-shaped back wall 43 of the insert 41 is provided with piercings 44 for passing through the strands of the tensioning cord 30.

In the connecting section 45 of the injection molded end member 32, a bore is formed to receive the shaft 47 of the drive wheel 36 provided with the circumferential ring 37. The other end of the spindle 47 is pivotally mounted in a closure 48 which can be secured to the side wall 50 of the injection molded end member 32 by means of screws 49 which are provided as an extension of the guide profile. Thus, the installation of the cord displacement system and the pivoting system of the strip lamellas 4 requires only the screwing in of two screws 49 on both sides of the closure cover 48.

Fig. 5 illustrates an embodiment of the carrier member 5, wherein a vertical spacer strip 66 is provided on each side of the carrier member 5. As shown in Fig. 4, the spacer strips 66 can be received by a chamber 23 of similar construction on the other side of the guide profile, so that there is virtually no need to enlarge the size of the guide profile.

11 The shaft 12, which is attached to the gear 10, carries on its lower part a piece of clip-shaped hanging member 3. The two opposed portions of the clip-type hanging member 3 are relatively flexible relative to one another due to the use of the plastics material, so that the strip 60 mounted on the ribbon section 4 and having a hanging tab 61 can be pierced through the gap between the clip jaws The hanger tab 61 has a thickened upper portion 62 which prevents the tape tab 4 from being accidentally pulled out of the clip-type hanger member 3. If the ribbon fin 4 is to be replaced, the upper part 62 of the hanger tab 61 only needs to be pushed out of the clip-shaped hanger 3 in the direction of arrow P7.

Referring now to Figures 6 and 7, two different embodiments of a friction clutch sliding over an overload between the transmission unit and the control rod 11 or the axle 12 of the suspension member 3 are described.

In the embodiment of Fig. 6, the central opening of the worm wheel 9 is provided with a longitudinal locking rib 50 'which fits into the groove 51 of the control rod 11. This allows longitudinal sliding of the worm wheel 9 and therefore sliding of the carrier members 5 relative to the guide bar 11, however, when the control shaft 11 is rotated, the worm wheel 9 can also rotate therewith. When turning the worm wheel 9 with screw thread 52,

- 12 * · * ········ ················································ · the freely rotatable gear wheel 10 also rotates in the carrier member. The shaft 12, passing through the central opening of the gear 10, ends with its upper end above the upper end of the gear 10, which fits into the bearing-like opening of the support member 5. In this way, the gearwheel 10 is automatically mounted in the bearing member 5. The gearwheel 10 is provided on its upper side with inwardly curved flanges 53 which resiliently lie on the conical surface 54 of the shaft 12. This flexible operation provides friction between the shaft 12 and the drive gear 10, so that when the shaft 12 becomes blocked due to an obstruction in front of the belt blade 4, the control rod 11 can be rotated further since the gear 10 is also freely rotatable relative to the shaft 12.

In the embodiment of Figure 7, the shaft 12 is similarly formed with a conical surface 54 that cooperates with the frictional edges 53 of the gear. The shaft 12 is further provided with a cam 55 which engages in the gap between the flanges 53 of the gearwheel 10, thereby creating a rotatable connection between the shaft 12 and the gearwheel 10.

Here, the control rod 11 is provided with three grooves 51 which cooperate with the inner latches 50 'of a friction sleeve 56. This friction sleeve 56 is provided with an outwardly projecting resilient rib 57 which cooperates with the inner wall of the worm wheel 9 central opening 58. ·· · · ··· ··· ··· ·

- With 13 teeth. In this embodiment, when turning the guide bar 11, it is conceivable that the guide bar 11 is rotated relative to the worm wheel 9, whereby the rib 57 may jump to the next tooth gap between the teeth 58. Here again, essentially a frictional coupling is obtained which allows a relative displacement between the control rod 11 and the rotation of the shaft 12.

In both embodiments, the thickened head of the shaft 12 rests on the upper edge of the flanges 53 for axial locking of the shaft 12 in the pinion 10. This is the second function of the flanges 53. The shaft 12 can thus be removed from the gearwheel 10 without having to slide the support members 5 out of the guide profile 1.

Finally, it is noted that the upper wall 24 of the guide profile 1 is formed with the outwardly facing edge edges 60 'as shown in Fig. 4, which can provide an arrangement of additional profiles 61'. These additional profiles 61 'may be provided in the form of continuous chambers 62 *, in which irregular shapes may also be employed. The profile 61 * can be attached to a ceiling strip 65 by means of a snap connection 64. This greatly facilitates assembly. Of course, other mounting systems may be used to arrange the guide profile 1 on the ceiling.

The invention is not limited to the embodiments described above.
