Description

The invention relates to a roll-up hanging with a winding shaft, on which the roll-up hanging can be wound and from which the roll-up hanging can be unrolled, wherein the roll-up hanging is formed from hanging segments that are connected to one another in segment rows which are oriented in the longitudinal direction of the winding shaft, each in one Segment row provided hanging segments rigid and the hanging segments of each segment row are connected to the hanging segments of adjacent segment rows pivotably about a pivot axis oriented in the longitudinal direction of the winding shaft, and adjacent hanging segments of each segment row are connected to one another via at least one plug connection.

Roll-up hangings of this type are regularly installed in a roller door system and are intended for opening and closing an underground car park entrance, a door, gate or window opening or the like opening in a building as required. Such roll hangings can be wound onto a winding shaft and can be unrolled from the winding shaft, which winding shaft can be driven to rotate either in one or the other direction of rotation with the aid of a shaft drive. The previously known roll hangings are mostly made of corrugated bars, with adjacent corrugated bars being connected to one another in an articulated manner at the wave tips of their wave shape with the aid of clip-shaped connectors. In order to prevent reaching through the diamond-shaped openings formed between the shafts of adjacent corrugated bars, the connectors of adjacent corrugated bars can each have a straight bar running through them. Due to the articulated connection of the rods forming the roll hangings, such roll hangings are on the winding shaft designed to be rolled up and unrolled again from the winding shaft. The bars of the roll-up hangings available on the market are mostly made of metal, which is why such a roll-up hangings made of metal bars usually have a high level of stability and security against break-ins, but at the same time also have a high weight. The high weight of the roll hangings available on the market requires powerful and correspondingly large shaft drives and limits the maximum dimensions of such roll hangings and the building openings closed by them so that the roll hangings ultimately do not become too heavy.

From the US 6,189,593 B1 we already know a roller door system that serves as a security lock that can be rolled up and down for a door opening. The previously known roller door system has a roller curtain of the type mentioned at the beginning with a winding shaft onto which the roller curtain can be wound and from which the roller curtain can be unrolled. The curtain of the previously known roller door system is formed from curtain segments. These hanging segments each have the outer contour of a horizontal H, the horizontally oriented longitudinal webs of this H-shape being tubular. These curtain segments are connected to one another in segment rows. For this purpose, stub axles are inserted into the tubular longitudinal webs of the H-shaped hanging segments, which protrude with their free stub ends alternately into the longitudinal webs of the adjacent hanging segments of a segment row provided above or below. In this way, the hanging segments provided in each segment row are rigidly connected to one another and the hanging segments of adjacent segment rows are connected to one another so as to be pivotable about a pivot axis oriented in the longitudinal direction of the winding shaft. Since the longitudinal webs of each hanging segment are only connected to one another via the one transverse web of this H-shape, the individual Curtain segments have a comparatively low load-bearing capacity and impact resistance, in particular if the curtain segments of the previously known roller curtain are designed as a plastic injection-molded part.

From the US 2012/090793 A1 a roll curtain is previously known, which was created to have increased impact resistance. This known roll curtain is formed from hanging segments which are plate-shaped and have two flat-sided main surfaces, two opposite longitudinal edges and two opposite transverse edges. Bush-shaped hinge parts are provided in the area of the longitudinal edges of the hanging segments. The evenly spaced hinge parts on one longitudinal edge of each hanging segment are offset from the hinge parts on the other longitudinal edge of the hanging segment in such a way that the hinge parts of adjacent hanging segments are in engagement with one another. In order to connect the hanging segments so that they can pivot with respect to one another, common hinge pins are inserted into the hinge parts of adjacent hanging segments, which pins define the pivot axis between the hanging segments. The hanging segments connected to one another in this way form an almost gapless roll-up hanging which, however, is comparatively heavy due to the plate-shaped design of the hanging segments. However, the dimensions of such a heavy roll-up curtain are limited so that the roll-up curtain can still be moved at all by a compact but sufficiently powerful shaft drive.

From the U.S. 6,041,847 A a roll-up curtain is previously known, which is essentially made of transparent plastic film, which allows passers-by to see through the roll-up curtain should continue to enable, for example, when this curtain secures and closes a shop window. For this purpose, the known roll-up curtain is formed from a plurality of two different components which are assigned to one another in pairs and each form a curtain segment. A first component of each hanging segment is plate-shaped and has an integrally formed tubular axis guide on one of its longitudinal edges. The assigned second component of each curtain segment has on its longitudinal edge facing away from the first component an axis guide receptacle in the form of a loop divided in cross section, which axis guide receptacle accommodates the axis guide of an adjacent curtain segment. The curtain segments are connected to one another by plug-in axles which are guided through the axle guides of the curtain segments. Since the axle guide receptacles on the second component of each hanging segment have only one narrow longitudinal slot, in which longitudinal slot the axle guide of an adjacent hanging segment engages, the mobility of the previously known roller hanging and its components is restricted.

From the U.S. 2,830,660 A a roll curtain is previously known, the curtain segments of which are each frame-shaped and made from a sheet metal strip. This sheet metal strip, from which the frame opening is cut out, has sleeve-like sheet metal formations on its longitudinal edges. Through these sleeve-like sheet metal deformations of the hanging segments adjacent to one another in rows, an axis can be implemented in each case, which serves as a pivot axis between the hanging segment rows. The production of the curtain segments formed as sheet metal parts from U.S. 2,830,660 A known roll hangings is comparatively complex.

There is therefore the particular object of creating a roll-up curtain of the type mentioned at the outset which, in comparison to its dimensions, can be produced comparatively easily and nevertheless sufficiently stable.

The inventive solution to this problem consists in the roll-up hanging of the type mentioned in particular in that at least a subset of the hanging segments forming the roll-up hanging is designed in the shape of a frame, that at least a subset of the hanging segments forming the rolling hanging is made of plastic, and that one of the adjacent hanging segments each segment row that has a hanging segment at least one outwardly pointing connecting pin of the plug connection, which is held in an associated and inwardly pointing connection opening of this plug connection in the adjacent hanging segment.

The roll-up curtain according to the invention is part of a roller door system which is used to open or close an underground car park entrance, a door, gate or window opening or the like opening of a building. A winding shaft, which is in drive connection with a shaft drive, is assigned to the roll-up curtain. The curtain is on the Winding shaft designed to be wound up and unrolled from the winding shaft and formed from a plurality of hanging segments which are connected to one another in segment rows. The segment rows formed from hanging segments connected to one another in rows are oriented in the longitudinal direction of the winding shaft. The curtain segments provided in each segment row are rigid and the curtain segments of each segment row are connected to one another so as to be pivotable about a pivot axis oriented in the longitudinal direction of the winding shaft with the curtain segments of adjacent segment rows. Since the roll curtain according to the invention is not made of solid rods, but essentially from flat hang segments, and since these hang segments can be made of any suitable material that is sufficiently stable and at the same time comparatively light, the roll hang according to the invention can also be made comparatively in larger dimensions easily run. Since the curtain is formed from a plurality of flat curtain segments, damage and deformations of the curtain can also be repaired retrospectively by replacing individual deformed segments in the affected part of the curtain.

In the roll-up curtain according to the invention, too, the adjacent curtain segments of each segment row are connected to one another via at least one plug-in connection. According to the invention it is provided that of the adjacent hanging segments of each segment row, the one hanging segment has at least one outwardly pointing connecting pin of the plug connection, which is held in an associated and inwardly pointing connection opening of this plug connection in the adjacent hanging segment.

Since adjacent hanging segments of each segment row can be rigidly connected to one another via at least one plug connection, it is possible to dispense with additional connectors between the curtain segments adjacent to one another in a row of segments. As a result, the effort associated with the production of the roll curtain according to the invention is additionally reduced. The at least one plug connection provided between adjacent hanging segments comprises an outwardly pointing connecting pin which is held in an associated and inwardly pointing connection opening of this plug connection in the adjacent hanging segment.

At least some of the hanging segments forming the roll-up hanging according to the invention are designed in the shape of a frame. Since the curtain segments are frame-shaped, the roll-up curtain is also characterized by its low weight and the frame-shaped curtain segments can also be designed to be visible and air-permeable in the area of the frame openings of their frame shape.

Since the flat shaped curtain segments of the roller blind according to the invention each have a certain inherent stability, it is possible that at least a subset of the curtain segments forming the roller blind is made of plastic. Such a roll curtain, the curtain segments of which are made of plastic, is characterized by a low weight and at the same time also by a high stability; Due to the low weight of the roll-up hanging according to the invention, this roll-up hanging is also possible in larger dimensions, and a few powerful, but much smaller shaft drives can also be used to roll up and down the roll-up hanging be used. It goes without saying that the roll-up curtain, in particular on its long sides of the curtain that is guided in guide rails, can additionally also have curtain segments that deviate from a frame-like shape.

So that the segment rows formed from adjacent hanging segments are inherently stable and rigid, it is advantageous if at least one plug connection provided between adjacent hanging segments has a connection opening with a non-circular opening cross-section in which a shape-adapted non-circular connecting pin is held.

The rolling up and unrolling of the hanging segments arranged in the segment rows is significantly facilitated if these hanging segments have a curved shape on their flat sides and preferably approximate to the shaft circumference of the winding shaft. In the cross section oriented transversely to the longitudinal direction of the winding shaft, the hanging segments thus have a curved shape which is at least approximated to the likewise curved shaft circumference of the winding shaft.

It can be advantageous if at least a subset of the curtain segments forming the roll curtain is made of fiber-reinforced plastic.

The manufacture and assembly of the roll-up hanging according to the invention is further facilitated if at least a subset of the hanging segments forming the roll-up hangings are designed in the same way.

A further developing embodiment according to the invention provides that the connecting pin of each plug connection can be detachably or non-detachably latched in the associated connection opening. If the connecting pin is permanently locked in the associated connection opening of the relevant plug connection, the high stability of this plug connection is permanently promoted. If, on the other hand, the connecting pin of each plug-in connection is releasably latched into the associated connection opening of this plug-in connection, the hanging segments affected in the event of damage to the roller blind can be replaced particularly easily.

In order in turn to articulate the individual rows of segments of the roll-up curtain according to the invention, an advantageous embodiment of the invention provides that on adjacent curtain segments of each segment row, stub axles that are assigned to one another and oriented in the longitudinal direction of the winding shaft protrude in pairs, and that the axle stubs that form the pivot axis between adjacent segment rows Pairs of stub axles are each rotatably mounted in stub axle openings on a stub axle counterpart, which axle stub counterparts protrude on the hanging segment of the respective adjacent row of segments. In this case, a pivot axis is formed on the axle stub pairs of the hanging segments that each form a segment row, around which this segment row and the respective adjacent segment row, which in turn has the required axle stub counterparts on its hanging segments, can be pivoted in such a way that the roller hanging formed from these rows of segments can be rolled up and down.

The manufacture of the roll curtain according to the invention is simplified and the assembly of this roll curtain is facilitated if each stub axle counterpart is at least two-part and has a first coupling piece and a second coupling piece, each of which carries an opening section of the stub axle openings assigned to a pair of stub axles, and that the coupling pieces of each axle stub counterpart can be connected to one another on at least one of their opposite sides and can preferably be locked to one another. By simply locking the coupling pieces provided on a counterpart stub axle, the stub axle openings can be formed in which the stub axles forming the pivot axis between adjacent rows of segments are rotatably mounted.

A particularly simple and easy-to-assemble embodiment according to the invention provides that the coupling pieces of each axle stub counterpart are connected to one another in a pivotable manner on one of their opposite sides, preferably via a film hinge. Thus, these coupling pieces of each axle stub counterpart can be pivoted on the film hinge provided between them in such a way that these coupling pieces can be connected to one another and preferably locked together at their coupling piece ends facing away from the film hinge.

An advantageous embodiment of the invention provides that at least a subset of the curtain segments forming the roll curtain in the area of a lengthwise direction of the Winding shaft oriented longitudinal side of the hanging segment has the stub axle counterpart and on one narrow side of the narrow sides provided on both sides of this hanging segment the connecting pin and on the opposite narrow side of the hanging segment the connection opening of the plug-in connections. There the stub axles can also be provided on both sides on the narrow sides or on the longitudinal side of these hanging segments facing away from the stub axle counterpart, which are intended to interact with the stub axle counterparts of the adjacent row of segments.

It is advantageous if at least a subset of the hanging segments has one of the axle stubs on their narrow sides, preferably in a partial area approximated to the longitudinal side opposite the axle stub counterpart.

A preferred development according to the invention provides that the curtain segments of adjacent segment rows are each connected to one another via a common axle element. If the curtain segments of adjacent segment rows are connected to one another via a common axle element, the structurally comparatively simple curtain segments can be produced with reduced effort.

A simple and preferred embodiment according to the invention provides that the common axle elements are guided by axle guides which are molded onto the facing longitudinal sides of the hanging segments of adjacent segment rows.

It can be useful if the hanging segments of adjacent segment rows have complementary axis guides on their long sides, such that at least one axis guide provided on one long side of each of these hanging segments is arranged in a recess between two axis guides on at least one hanging segment of the adjacent segment row in such a way that that these axis guides are flush with one another. Due to the aligned axis guides a common and preferably rod-shaped axle element can then be inserted. In order to create a roll-up curtain whose rows of interconnected curtain segments and whose segment rows formed from the curtain segments are connected at most a small distance from one another, it is advantageous if the curtain segments connected via a common axis element are spaced apart first axis guides on their first longitudinal side and on their opposite one carry at least one second axis guide on the second longitudinal side, and if a recess is formed at a distance from the first axis guides, into which recess the at least one second axis guide of an opposite, preferably structurally or formally identical curtain segment of the adjacent segment row engages in such a way that the first axis guides of the A segment row provided curtain segments are aligned with the second axis guides of the opposite curtain segments of the adjacent segment row.

The adjacent hanging segments can be put together in a mosaic-like interlocking fashion to form a flat roll-up hanging if the first axis guides of each of these hanging segments have half the length in the longitudinal direction of the axis element compared to the at least one second axis guide.

In order to avoid tilting of the curtain segments lying against one another in a segment row, it is advantageous if at least one outwardly pointing connecting pin protrudes on one transverse side of each of these curtain segments and if the at least one connecting pin is at a distance from the corners between this transverse side and the long sides this hanging segment is arranged. The inserted through the axis guides of the curtain segments Axle elements can be designed as metal rods, for example. However, in order to keep the weight of the curtain as low as possible in this area as well, it is advantageous if at least some of the axle elements of a curtain are made from fiber-reinforced plastic, if appropriate.

The hanging segments of the roller hanging according to the invention, which are connected to one another in rows, can rest against one another at the smallest possible distance if at least a subset of the hanging segments have a rectangular outer contour in plan view.

In order to prevent reaching through between the hanging segments adjoining one another in a row, it is advantageous if the transverse sides of the hanging segments arranged in a row of segments are each preferably in contact with one another without a gap.

The hanging segments of the roll-up hanging according to the invention can also be produced with a low weight and reduced material expenditure if the frame-shaped hanging segments delimit at least one frame opening.

An embodiment is preferred in which the frame opening of these hanging segments is hexagonal and / or diamond-shaped.

Developments according to the invention emerge from the following description of preferred exemplary embodiments in conjunction with the claims and the drawings.

In the following, the invention will be more preferred by way of example Embodiments explained in more detail.

In the Figures 1 to 3 and the Figures 13 to 15 are different versions 1, 20 of a roll curtain shown in different views. The roller hangings 1, 20 are part of a roller door system which is used to open or close an underground car park entrance, a door, gate or window opening or the like opening of a building. As in the Figures 2 and 3 is shown by way of example, the roll hangings 1, 20 are each assigned a winding shaft 2, which is in drive connection with a manual or electric shaft drive. In order to make the winding shaft 2 as stable as possible, the in Figures 2 and 3 shown winding shaft 2 has a non-circular and in particular an octagonal shaft cross-section.

As in the Figures 2 and 3 Also shown by way of example, the roll hangings 1, 20 can be wound onto the winding shaft 2 and are designed so that they can be unrolled from the winding shaft 2. The roller hangings 1, 20 are made up of a plurality of hanging segments 3; 21 formed, of which at least the subset shown here of hanging segments 3; 21 are designed in the same or identical form. The hanging segments 3; 21 of the Figures 1 to 3 and the Figures 11 to 15 The roller hangings 1, 20 shown are connected to one another in segment rows 4. The segment rows 4 are oriented in the longitudinal direction of the winding shaft 2. The hanging segments 3; 21 rigid and the hanging segments 3; 21 of each row of segments 4 with the hanging segments 3; 21 adjacent rows of segments 4 are connected to one another so as to be pivotable about a pivot axis oriented in the longitudinal direction of the winding shaft 2.

Since the roller hangings 1, 20 shown here are not made of solid rods, but essentially of the flat hanging segments 3; 21 are formed, and there these hanging segments 3; 21 can be made of any suitable material that is sufficiently stable and at the same time preferably light, the roll hangings 1, 20 can be made comparatively light even in larger dimensions. Since the curtains 1, 20 from a plurality of flat curtain segments 3; 21 are formed, damage and deformations of the roller hangings 1, 20 can also be retrospectively replaced by replacing individual deformed hanging segments 3; 21 in the roll-up curtain 1 or 20. The adjacent hanging segments 3; 21 of each row of segments 4 are each connected to one another via at least one plug connection 5. For this purpose, one of two adjacent hanging segments 3; 21 at least one outwardly facing connecting pin 6; 26, which is in an associated and inwardly facing connection opening 7; 27 of this plug connection 5 in the adjacent hanging segment 3; 21 of the respective row of segments 4 is held. As if from looking at the Figures 4, 5 and 7 as well as the Figures 11 to 20 becomes clear, engages the connecting pin 6; 26 of each plug connection 5 into the associated connection opening 7; 27 of this connector 5 a.

As seen from the side views in Figure 3 as well as in the Figures 13 to 15 It becomes clear that the hanging segments 3; 21 on their flat sides a curved cross-sectional shape approximated to the shaft circumference of the winding shaft 2. This curved cross-sectional shape promotes space-saving rolling up of the roll curtain 1, 20 on the winding shaft 2. Have the hanging segments 3; 21 of the curtains 1, 20 in the position of use with their convexly curved flat side facing outwards, the curtain 1, 20 is capable of this, through the curved flat sides of the curtain segments 3; 21 formed outside to withstand even greater compressive forces. At least the subset shown here of the curtain segments 3 forming the roller hangings 1, 20; 21 is designed in the shape of a frame. The hanging segments 3; 21 of the roll hangings 1, 20 shown here are made of plastic and in particular of fiber-reinforced plastic. In order to be able to design the hanging segments so as to be visually and air-permeable in the area of the frame openings of their frame shape, at least a subset of the hanging segments 3 forming the roller hanging can also have a spectacle-shaped outer contour.

So that the hanging segments 3; 21 des in the Figures 1 to 3 can be rigidly connected to each other via the plug-in connections 5 provided between them, the plug-in connection 5 provided between the adjacent hanging segments 3 of the roller blind 1 each has a connection opening 7 with a non-circular opening cross-section, in which the shaped non-circular connecting pin 6 is held.

From looking at the Figures 1 , 2 , 4, 6 and 8 to 10 it becomes clear that on adjacent hanging segments 3 of each segment row 4 of the roller hanging 1, stub axles 9, which are assigned to one another in pairs and oriented in the longitudinal direction of the winding shaft 2, protrude. The axle stub pairs forming the pivot axis between adjacent segment rows 4 are each rotatably mounted in axle stub openings 10 on an axle stub counterpart 11, which axle stub counterparts 11 protrude from the hanging segments 3 of the respectively adjacent segment row 4. These stub axle counterparts 11 can be rigidly and preferably integrally connected to the hanging segment 3 assigned to them. However, it is particularly easy to roll up and unroll of the curtain 1 to ensure that is in the Figures 4 and 6 Preferred embodiment shown in more detail, in which the corresponding stub axle counterpart 11 is held on the hanging segment 3 assigned to it about an axis of rotation 12, which axis of rotation 12 is provided on the respective hanging segment 3.

From a comparison of the Figures 4 and 6 It becomes clear that each stub axle counterpart 11 is at least two-part and has a first coupling piece 13 and a second coupling piece 14, each of which carries an opening section 15, 16 of the stub axle openings 10 assigned to a pair of stub axles. The coupling pieces 13, 14 are pivotally connected to one another at one pair of their opposite coupling piece ends via a film hinge 19 and can be connected to one another and preferably latched to one another at the other pair of the opposite coupling piece ends. For this purpose, a locking pin 17 is provided on one of the opposite coupling piece ends which engages in a locking opening 18 of the stub axle counterpart 11.

The hanging segments 3 of the roller hanging 1 have a frame-shaped or glasses-shaped outer contour. At least the subset of the hanging segments 3 shown here has the stub axle counterpart 11 in the area of a longitudinal side of each of these hanging segments 3 oriented in the longitudinal direction of the winding shaft 2 and the connecting pin 6 on one narrow side of the narrow sides of this hanging segment 3 and the connecting pin 6 on the opposite narrow side Curtain segment 3, the connection opening 7.

As seen from the side view in Figure 3 It becomes clear that the hanging segments 3 have on their flat sides a curved cross-sectional shape approximated to the shaft circumference of the winding shaft 2. This curved cross-sectional shape promotes space-saving rolling up of the roll curtain 1 on the winding shaft 2.

At least the subset shown here of the curtain segments 3 forming the roll-up curtain 1 is designed in the shape of a frame and has a spectacle-shaped outer contour. The hanging segments 3, 21 of the roller hangings 1, 20 shown here are made of plastic and in particular of fiber-reinforced plastic.

At least the subset of the hanging segments 3 shown here has the stub axle counterpart 11 in the region of a longitudinal side of each of these hanging segments 3 oriented in the longitudinal direction of the winding shaft 2 and the connecting pin 6 on one narrow side of the narrow sides of this hanging segment 3 and the connecting pin 6 on the opposite narrow side Curtain segment 3, the connection opening 7 of the plug connections 5. On the side opposite the stub axle counterpart 11 and in particular on the narrow sides of each of these hanging segments 3, one of the stub axles 9 is provided in a partial area approximated to the longitudinal side opposite the stub axle counterpart 11.

While the hanging segments 3 of the in the Figures 1 to 3 Roll hanging 1 shown are designed so that their molded axle stub pairs the pivot axes between Form adjacent rows of segments 4 are in the Figures 11 to 15 The curtain 20 shown, the curtain segments 21 of adjacent segment rows 4 are each connected via a common axle element 22, which preferably extends over the entire width of the curtain 20. These axle elements 22, which connect adjacent rows of segments 4 to one another, are rod-shaped. The axle elements 22 of the Figures 11 to 15 The blinds shown are guided in axis guides 23, 24 which are formed on the mutually facing longitudinal sides of the blind segments 21 of adjacent segment rows 4 of the blinds 20.

In order to be able to design at least a subset of the curtain segments 21 forming the roll-up curtain 20 in the same manner and in particular with the same shape, the curtain segments 21 of adjacent segment rows 4 have complementary axis guides 23, 24 on their longitudinal sides, in such a way that at least one, on one longitudinal side of each of these curtain segments 21 provided axle guide 23, 24 engages in a recess 25 between two axle guides 23 on at least one hanging segment 21 of the adjacent row of segments 4 in such a way that these axle guides 23, 24 are aligned with one another. The axis guides which are aligned with one another can then be used to insert the axis element 22, which connects the adjacent segment rows 4 with one another in an articulated manner and serves as a pivot axis between these segment rows 4.

From a comparison of the Figures 11 to 15 on the one hand and the Figures 16 to 20 on the other hand, it can be seen that the hanging segments 21 connected via a common axle element 22 are spaced apart from one another on their first longitudinal side and first axle guides 23 on their opposite second Long side carry at least one second axis guide 24, and a recess 25 is formed at a distance from the first axis guides 23, into which recess 25 the at least one second axis guide 24 of an opposite hanging segment 21 of the adjacent segment row 4 engages in such a way that the first axis guides 23 of the in of the one segment row 4 provided curtain segments 21 with the second axis guides 24 of the opposite curtain segments 21 of the adjacent segment row 4 are aligned.

So that the axis guides 23, 24 of the curtain segments 21 forming the roller blind 20 interlock in such a way that the flat roller blind is formed, the first axis guides 23 of each of these blind segments 21 each have half the length in the longitudinal direction of the axis element compared to its at least one second axis guide 24 22 on.

From a comparison of the Figures 16 to 20 it becomes clear that on one transverse side of each of these hanging segments 21 at least one outwardly pointing connecting pin 26 protrudes, which is arranged at a distance from the corners between this transverse side and the long sides of this hanging segment 21. The connecting pin 26, which is formed on the side of the hanging segment 21 and engages in the connecting opening 27 on the adjacent hanging segment 21, interacts with the axle elements 22 of the roller hanging 20, which each form a pivot axis, in such a way that the segment rows 4 of the roller hanging 20 are deformable around the axle elements 22 forming the pivot axis without the curtain segments 21 resting against one another in a segment row 4 being able to pivot with respect to one another.

The axle elements 22 of the Roll hangings 20 can be made of metal or some other suitable material. In order to design the roll-up curtain 20 with the lowest possible weight, however, a preferred embodiment provides that these axle elements 22 are made of plastic and in particular of fiber-reinforced plastic. While the axle guides 23, 24 each have a preferably circular guide opening, the outer circumference of each axle element 22 is delimited by a round enveloping circle.

From a comparison of the Figures 16, 17 and 19 it can be seen that the hanging segments 21 forming the roll-up hanging 20 each have a rectangular outer contour in plan view. The transverse sides of the hanging segments 21 arranged in a row of segments are in contact with one another without any gaps, and without gaps here also means a distance between the hanging segments 21 in which a person cannot reach with his fingers.

The frame-shaped hanging segments 21 of the in the Figures 11 to 15 The curtain 20 shown delimit a frame opening which is hexagonal and almost diamond-shaped. Due to this frame opening and its hexagonal shape, the hanging segments 21 can be produced with a reduced weight and material expenditure, without the stability of the hanging segments 21 being impaired as a result.

The longitudinal sides of the roll hangings 1, 20, which are oriented in the vertical direction, are guided in sliding guides, not shown here, which sliding guides each have a guide groove for this purpose. In order to be able to produce the roll-up curtain in different widths if necessary, at least a subset of the can be inserted into the sliding guides engaging hanging segments have a reduced width. In a modular roll-up system, it is possible to provide hanging segments with different grid dimensions that can be mounted on the vertically oriented long sides of the roll-up hanging.
