The blind includes first and second end rails 1 . 2 and a plurality of in the region between the first and second end rail 1 . 2 arranged slats 3 , The slats 3 are of two ladder cords 4 held, which are spaced apart in the longitudinal direction of the slats. The ladder cords 4 each comprise two longitudinal cords 5 , on both sides of the slats 3 parallel to the adjustment direction 6 run. Between the longitudinal cords 5 run cross-straps 7 on which the slats 3 rest. Instead of an overlay on cross cords, the slats could 3 also directly or via connecting cord pieces with the longitudinal cords 5 be connected. It can also double-stranded cross-cords 7 be present, with a respective blade 3 between the two strands lies.

The end rails 1 . 2 are along the adjustment 6 opposite the first and second tension cords 8th . 9 adjustable. A respective tension cord 8th . 9 is at two attachment points 10 . 11 ; 12 . 13 attached. The attachment points 10 . 11 ; 12 . 13 a respective tension cord 8th . 9 lie in the adjustment direction 6 seen on both sides of the end rails 1 . 2 , Slats 3 and ladder cords 4 formed unit. If the blind is used as a window or door hanging, so are the attachment points 10 . 11 ; 12 . 13 a respective tension cord 8th . 9 on opposite edges 14 . 15 the window or door opening.

At the attachment points 10 to 13 are fastening parts 16 determined with which the tension cords 8th . 9 via connecting parts 17 are connected.

A respective tension cord 8th . 9 runs starting from one of its attachment points 10 . 12 parallel to the adjustment direction 6 to the first end rail 1 , continue through this parallel to the longitudinal extent of the first end rail 1 , further from the first end rail 1 to the second end rail 2 parallel to the adjustment direction 6 , continue through the second end rail 2 parallel to the longitudinal extent of the second end rail 2 and further from the second end rail 2 to your other attachment point 11 . 13 , A respective tension cord 8th . 9 in this case runs through the two end rails 1 . 2 in opposite directions. Furthermore, the two tension cords run 8th . 9 starting from the fastening points arranged on the same side of the blind 10 . 12 to their attachment points on the other side of the blind 11 . 13 seen in opposite directions through a respective end rail 1 . 2 ,

The end rails 1 . 2 are formed in the embodiment shown as a hollow body and have frontal openings 18 on, through which the tension cords 8th . 9 enter and exit. Instead, it would also be conceivable and possible for guide means to be present, for example guide straps which hold the tensioning cords 8th . 9 at an Au ßenseite a respective end rail 1 . 2 in the longitudinal direction of the same lead.

The tension cords 8th . 9 are under tension and the end rails 1 . 2 are held between them. These are at the longitudinal ends of the end rails 1 . 2 border pieces 19 . 20 arranged with which the end rails 1 . 2 are connected and over or through which the tension cords 8th . 9 run, as explained below in more detail.

The longitudinal cords 5 the ladder cords 4 are on those pages 21 . 22 the end rails 1 . 2 set in the untwisted state of the slats 3 and the end rails 1 . 2 facing each other. This unmoved state is in the 1 and 2 shown. The distance in which the longitudinal cords 5 at the end rails 1 . 2 are fixed, in this case correspond to the width b of the slats 3 , At least this distance corresponds to a value of two-thirds of the width b of the slats 3 ,

The end rails 1 . 2 are preferably slightly wider than the slats 3 , Their lengths are preferably slightly less than that of the slats 3 , with the tension cords 8th . 9 in edge sections of the longitudinal extension of the slats 3 enforce arranged window recesses. Instead, the tension cords could 8th . 9 the slats 3 z. B. also in the field of ladder cords 4 push through.

Also other types of related to the longitudinal directions of the longitudinal cords 5 opposite the end rails 1 . 2 immovable connections of the longitudinal cords 5 with the end rails 1 . 2 are conceivable and possible. So could the longitudinal cords 5 for example, the end rails 1 . 2 also penetrate through holes and on the sides 21 . 22 be attached opposite backs. Again, the longitudinal cords would 5 a respective ladder cord 4 at a distance from the respective end rail 1 . 2 go out, which corresponds to at least two-thirds of the width b of the slats, preferably the width b of the slats 3 equivalent.

The end rails 1 . 2 are about imaginary swivel axes 23 . 24 pivotable, which are parallel to their longitudinal extent. For this purpose, the end rails 1 . 2 about their swivel axes 23 . 24 rotatable on the edge pieces 19 . 20 stored. The edge pieces 19 . 20 are in contrast, apart from a game, to the swivel axes 23 . 24 kept non-rotatable, and that of at least one of the tension cords 8th . 9 that with this edge piece 19 . 20 works together. For this purpose, this tension cord runs 8th . 9 over or through the edge piece 19 . 20 , wherein one parallel to the adjustment 6 extending section of the tension cord 8th . 9 in the direction perpendicular to the direction of adjustment 6 and the pivot axis 23 . 24 clamped plane positively against the edge piece 19 . 20 is guided, preferably by the tension cord 8th . 9 through a parallel to the adjustment 6 running slot 29 or extends through such a bore. The game, about which a pivoting of the edge piece 19 . 20 around the pivot axis 23 . 24 is possible, is preferably less than 10 °.

In this embodiment, the respective edge piece has 19 . 20 for rotatably supporting the end rail 1 . 2 one in the direction of the pivot axis 23 . 24 the end rail 1 . 2 projecting pin 30 , This protrudes into a frontal recess 31 the end rail 1 . 2 , The pin 30 is hollow or has a in the axial direction of the pivot axis 23 . 24 extending bore. The front side is the pin 30 open. The tension cords 8th . 9 run through this pin 30 and pass through the front opening 18 the end rail 1 . 2 in this one.

For holding the respective end rail 1 . 2 in the set pivot position about its pivot axis 23 . 24 is one between the end rail 1 . 2 and the respective edge piece 19 . 20 acting locking mechanism provided. The pivot position of the respective end rail 1 . 2 is thus latched adjustable.

In the embodiment according to the 1 to 6 has the respective frontal recess 31 the end rail 1 . 2 on its cylindrical, the pivot axis 23 . 24 facing lateral surface a toothing 32 , which is circular in cross-section. The pin 30 has an outwardly projecting latching projection 33 that with the teeth 32 interacts. Through both sides of the locking projection 33 arranged, parallel to the pivot axis 23 . 24 extending slot-shaped recesses 34 a tongue is formed, on which the latching projection 33 is formed, this tongue has a certain elasticity. At a twist of the end rail 1 . 2 opposite the associated edge pieces 19 . 20 can the latching projection 33 thus move by compression of the tongue over the tooth combs. Each set pivot position is by the in the toothing 32 engaging latching projection 33 positively detected.

The gearing 32 could also be formed partially circular in cross-section.

The two sides of the end rails 1 . 2 arranged edge pieces 19 . 20 serve in this embodiment, as a spacer relative to the edge of the window or door opening and they protrude for this purpose, the slats 3 connected at both ends tig. The facing away from each other frontal surfaces of the edge pieces 19 . 20 are designed here as sliding surfaces.

As already mentioned, the edge pieces have 19 . 20 from their frontal, from the end rails 1 . 2 each outgoing surfaces outgoing slots 29 on, which are parallel to the adjustment 6 extend and through the respective tensioning cord 8th . 9 is guided. The from an edge of the edge pieces 19 . 20 outgoing slots 29 go in one to the pivot axis 23 . 24 coaxial circular depression 35 over to the opposite edge of the edge piece 19 . 20 is open to the passage of the other tension cord 8th . 9 , The edge pieces 19 . 20 could also with differently shaped depressions for the passage of the tension cords 8th . 9 and / or be provided with appropriate holes.

While in the embodiment according to the 1 to 6 the teeth of the teeth 32 relative to the pivot axis 23 . 24 protrude radially are in the embodiment according to the 7 and 8th gearing 32 with in the direction parallel to the pivot axis 23 . 24 protruding teeth present. These gears 32 are at the right angle to the pivot axis 23 . 24 standing end faces of the end rails 1 . 2 arranged, with their tooth combs radially to the pivot axis 23 . 24 run. The locking projection 33 is at one of the front end surface of the end rail 1 . 2 opposite at right angles to the pivot axes 23 . 24 standing surface of the edge piece 19 . 20 arranged. The locking projection 33 is due to the tension of the tension cords 8th . 9 in engagement with the toothing 32 held and can at a pivoting of the end rail 1 . 2 around its pivot axis 23 . 24 be transferred over the tooth combs. Also by such training is the respective end rail 1 . 2 thus locked in different pivot positions adjustable.

In both embodiments of the invention shown, the teeth could also on the edge pieces 19 . 20 and the locking projections 33 at the end rails 1 . 2 be arranged.

In both embodiments of the invention shown is with the end rails 1 . 2 in each case at least one operating element 25 . 26 articulated, and that is the operating element 25 . 26 around a parallel to the longitudinal direction of the respective end rail 1 . 2 lying axis 27 . 28 opposite the end rail 1 . 2 pivotable. The controls 25 . 26 can be held by friction or by locking means in a respective set pivoting position.

Both end rails 1 . 2 are overcoming the friction between the tension cords 8th . 9 and the respective one from the end rail 1 . 2 and the edge pieces 19 . 20 existing unit in the adjustment 6 adjustable. The blind can thus be pushed together from below and / or from above more or less far. In the 1 and 2 a state is shown in which the blind is partially pushed together both from the top and from the bottom. For adjusting the inclination of the slats 3 becomes the topmost first rail 1 around its pivot axis 23 pivoted. In order to give even the lowest slats the same pivot position, also the lower end rail 2 around its pivot axis 24 be pivoted so that they are parallel to the upper end rail 1 is aligned. The blind can also be mounted in such a way that the adjustment direction 6 obliquely to the vertical or horizontally. For a horizontal installation of the blind, the slats should be with the ladder cords 4 be connected so that they to the longitudinal cords 5 are immovable (for example, are inserted between double-stranded cross-cords). An adjustment of the inclination of the slats is at least in the fully telescoped state of the two end rails 1 . 2 possible.

The displacement and pivoting of the end rails 1 . 2 can each by pressing a single control element 25 . 26 be performed.

To adjust the slats 3 in the pivoting of the first and / or second end rail 1 . 2 not to hinder, are the pivot axes 23 . 24 as close as possible to the pages 21 . 22 the end rails 1 . 2 , in the untwisted state of the end rails 1 . 2 lie opposite each other.

Various modifications of the embodiments shown are conceivable and possible without departing from the scope of the invention. For example, the gearing could be 32 also on the respective edge piece 19 . 20 and the locking projection 33 at the end rail 1 . 2 be arranged.

Although the arrangement of edge pieces 19 . 20 on both end rails 1 . 2 is preferred, could only at the first end rail 1 such edge pieces 19 . 20 to be available. The second end rail 2 Then it would be right between the tension cords 8th . 9 frictionally held and could in its pivotal position about the pivot axis 24 through the tension cords 8th . 9 be determined by friction.

It would be conceivable and possible, too, at the first end rail 1 and / or the second end rail 2 only at one longitudinal end an edge piece 19 . 20 provided. If edge pieces on both sides 19 . 20 in front so could just be between one of the edge pieces 19 . 20 and the end rail 1 respectively. 2 a locking mechanism for positive retention of each set pivot position act.

The end rails 1 . 2 can be formed in one or more parts. For example, the end rails 1 . 2 each having a base body and at the two longitudinal ends of the base body attached to this end caps, via which the pivotable, latched connection with the edge pieces 19 . 20 he follows.

The rotatable mounting of the end rail 1 . 2 in the margin piece 19 . 20 could also be done in a different way than shown, for example, instead of a hollow cylindrical pin 30 also a half-shell-shaped pin 30 to be available. Instead of a slot 29 or a bore through which or through which the tensioning cord 8th . 9 runs, could be the holder of the edge piece 19 . 20 to prevent its pivoting about the pivot axis 23 . 24 through at least one of the tension cords 8th . 9 done in other ways, for example, in the axial direction of the pivot axis 23 . 24 from the edge piece 19 . 20 protruding nubs, between which the tension cord 8th . 9 runs, leaving the tension cord 8th . 9 in such a training not through but over the edge piece 19 . 20 could run.

In the tension cords 8th . 9 can also be arranged tension springs.
