Description

The invention relates to a Rollbehang with a winding shaft on which the Rollbehang aufwickelbar and from which the Rollbehang is unrolled.

Such Rollbehänge are regularly installed in a Rolltoranlage and determines the need for opening and closing an underground car park entrance, a door, gate or window opening or the like opening of a building. Such Rollbehänge can be wound on a winding shaft and configured unrollable from the winding shaft, which winding shaft is rotatably driven by means of a shaft drive in either one or the other direction. The prior art roll hangers are usually made of corrugated rods, wherein adjacent corrugated rods are hinged together at the shaft tips of their waveform by means of clamp-shaped connectors. Thus, a penetration is prevented by the forming between the waves of adjacent corrugated diamond-shaped openings, the connectors of adjacent corrugated bars can also be traversed by a straight rod. Due to the articulated connection of the roll curtain forming rods are such Rollbehänge on the winding shaft rolled up and designed to be unrolled again by the winding shaft. The rods of the roll hangers on the market are usually made of metal, which is why such, made of metal rods roll curtain usually has a high stability and burglary - - but at the same time also has a high weight. The high weight of the roll hangers on the market requires powerful and corresponding large shaft drives and limits the maximum dimensions of such roll hangings and their closed building openings so that the roll hangings ultimately not be too heavy.

There is therefore in particular the task of creating a roll curtain of the type mentioned, which can be made comparatively light and yet sufficiently stable compared to its dimensions.

The inventive solution to this problem is in the Rollbehang of the type mentioned in particular that the Rollbehang is formed from Behangsegmenten, which are interconnected in rows of segments, which are oriented in the longitudinal direction of the winding shaft, and that each provided in a segment row Behangsegmente rigid and the curtain segments of each segment row are connected to the hanging segments of adjacent rows of segments about a pivot axis oriented in the longitudinal direction of the pivot axis pivotally connected to each other.

The Rollbehang invention is part of a Rolltoranlage, which serves for opening or closing an underground car park entrance, a door, gate or window opening or the like opening of a building. The roll hanging is associated with a winding shaft which is in drive connection with a shaft drive. The Rollbehang is on the Winding shaft wound up and configured unrollable from the winding shaft and formed from a plurality of Behangsegmenten, which are interconnected in rows of segments. The rows of segments formed from row-connected curtain segments 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 pivotally connected to the curtain segments of adjacent rows of segments about a pivot axis oriented in the longitudinal direction of the winding shaft. Since the roll curtain according to the invention is not formed of solid bars, but essentially of flat Behangsegmenten, and since these Behangsegmente can be made of any suitable material which is sufficiently stable and at the same time comparatively light, the roll curtain according to the invention even in larger dimensions still comparatively easy to run. Since the Rollbehang is formed from a plurality of flat Behangsegmente, damage and deformations of Rollbehangs can also be improved later by replacing individual deformed Behangsegmente in the affected portion of the Rollbehangs.

It is advantageous if the adjacent Behangsegmente each segment row are connected to each other via at least one connector, and if the one Behangsegment of each adjacent Behangsegmente at least one outwardly facing connecting pin of the connector having in an associated and inwardly facing connection opening of this connector is held in the adjacent hanging segment. Since neighboring curtain segments of each segment row can be rigidly connected to one another via at least one plug connection, can be dispensed with additional connectors between the hanging segments adjacent in a segment row. As a result, the expense associated with the production of the roll curtain according to the invention is additionally reduced. The at least one provided between adjacent Behangsegmenten connector comprises an outwardly facing connecting pin which is held in an associated and inwardly facing connection opening of this connector in the adjacent Behangsegment.

Thus, the segment rows formed from adjacent Behangsegmenten are formed in stable and rigid, it is advantageous if at least one provided between adjacent Behangsegmenten connector has a connection opening with non-circular opening cross-section, in which a shape-matched non-circular Vebindungszapfen is held.

The winding and unwinding of arranged in the rows of segments Behangsegmente is greatly facilitated if these Behangsegmente have on their flat sides a curved and preferably approximated to the shaft circumference of the winding shaft shape. The Behangsegmente thus have in the transverse to the longitudinal direction of the winding shaft oriented cross-section on a curved shape, which is at least approximated to the also curved shaft circumference of the winding shaft.

It may be advantageous if at least a subset of the hanging curtain forming Behangsegmente are disc-shaped or frame-shaped. If these curtain segments are disk-shaped, the roll curtain in the region of at least the curtain segments forms a privacy-visible screen. In contrast, the curtain segments are frame-shaped formed, the Rollbehang still additionally characterized by a low weight and the frame-shaped Behangsegmente can be made visible and permeable to air in the frame openings of their frame shape.

It is understood that the Rollbehang may also have Behangsegmente particular on its guided in guide rails curtain long sides, which differ from a disc or frame-shaped shape and in particular from a spectacle-shaped outer contour.

Since the flat-shaped Behangsegmente each have a certain intrinsic stability, it is possible that at least a subset of the rolling curtain forming curtain segments made of plastic and in particular made of fiber-reinforced plastic. Such a Rollbehang whose Behangsegmente are made of plastic and in particular of fiber-reinforced plastic, characterized by a low weight and at the same time by a high stability; Due to the low weight of such Rollbehangs the realization of this Rollbehangs is also possible in larger dimensions and for winding and unrolling such Rollbehangs also less powerful, but much smaller shaft drives can be used.

The manufacture and assembly of Rollbehangs invention is additionally facilitated if at least a subset of the roll curtain forming Behangsegmente is formed similar.

A further embodiment according to the invention provides that the connecting pin of each plug connection in the associated connection opening is detachably or non-releasably latched. If the connecting pin in the associated connection opening of the relevant connector inextricably locked, the high stability of this connector is permanently favored. If the connecting pin of each connector, on the other hand, is releasably locked in the associated connection opening of this connector, the curtain segments affected in the event of damage to the curtain can be exchanged particularly easily.

In order in turn to connect the individual rows of segments of Rollbehangs invention hingedly together, provides an advantageous embodiment according to the invention that protrude to adjacent Behangsegmenten each segment row in pairs associated with each other and oriented in the longitudinal direction of the winding shaft axle stub, and that the pivot axis forming between adjacent rows of segments Achsstummel pairs are each rotatably mounted in stub axle openings on a stub axle counterpart, which stub axle counterparts protrude to the curtain segment of each adjacent segment row. In this case, forms on the stub axle pairs of each segment row forming Behangsegmente a pivot axis, around which this segment row and each adjacent thereto segment row, which in turn has the required Achsstummel counterparts on their Behangsegmenten are pivotable so that from these Segment rows formed roll hanging up and unroll.

The production of Rollbehangs invention is simplified and the assembly of this Rollbehangs is facilitated if each stub axle counterpart at least two parts and has a first coupling piece and a second coupling piece, each one Opening portion of a stub axle pair associated stub openings, and that the coupling pieces of each stub axle counterpart on at least one of its opposite sides are connected to each other and preferably latched together. By merely locking the provided on a stub axle counterpart couplings the stub axle openings may be formed, in which the pivot axis between adjacent rows of segments forming stub axle are rotatably mounted.

In this case, a particularly simple and easily mountable embodiment according to the invention provides that the coupling pieces of each axle stub counterpart are pivotally connected to one another on one of their opposite sides, preferably via a film hinge. Thus, these coupling pieces of each stub axle counterpart can be pivoted on the film hinge provided between them such that these coupling pieces are connectable to each other at their coupling hinge ends remote from the film hinge and preferably latched together.

An advantageous embodiment of the invention provides that at least a subset of the hanging curtain forming Behangsegmente has a spectacle-shaped outer contour.

An advantageous embodiment of the invention provides that at least a subset of the hanging curtain forming Behangsegmente oriented in the longitudinal direction of the winding shaft longitudinal side of the Behangsegments the stub axle counterpart and on one narrow side of both sides provided narrow sides of this Behangsegmentes the connecting pin and on the opposite Narrow side of the hanging segment has the connection opening of the connectors. there can be provided on both sides of the narrow ends or on the side opposite the stub axle counterpart longitudinal side of these Behangsegmente the stub axle, which should cooperate with the stub axle counterparts of the adjacent segment row.

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

A preferred embodiment according to the invention provides that the Behangsegmente adjacent segments rows are each connected to each other via a common axle. If the curtain segments of adjacent rows of segments 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 integrally formed on the mutually facing longitudinal sides of the curtain segments of adjacent rows of segments.

It may be expedient if the Behangsegmente adjacent segment rows have on their longitudinal sides complementary axle guides, such that at least one provided on one longitudinal side of each of these Behangsegmente axle guide is arranged in a recess between two axle guides on at least one hanging segment of the adjacent segment row such that these axle guides are aligned with each other. Due to the aligned axis guides can then be inserted a common and preferably rod-shaped axle. In order to create a Rollbehang, the rows of interconnected Behangsegmente and its segments formed from the Behangsegmenten connected at most a small distance from each other, it is advantageous if the connected via a common axis element Behangsegmente on their first longitudinal side spaced apart first axle guides and at its opposite wear at least a second axis guide on the second longitudinal side, and when at the distance of the first axle guides a recess is formed, in which recess engages the at least one second axle guide of an opposite, preferably construction or same shape Behangsegmentes the adjacent segment row such that the first axle guides in the one segment row provided Behangsegmente aligned with the second axis guides the opposite Behangsegmente the adjacent segment row.

The curtain segments adjacent to one another can be assembled in a mosaic-like manner into a flat roll curtain if the first axle guides of each of these curtain segments each have half the longitudinal extension in the longitudinal direction of the axle element compared to the at least one second axle guide.

In order to avoid tilting the hanging in a row of segments Behangsegmente, it is advantageous if at least one outwardly facing connecting pin projecting on the one transverse side of each of these Behangsegmente and if the at least one connecting pin at a distance from the corners between this transverse side and the longitudinal sides This Behangsegmentes is arranged. The inserted through the axle guides the Behangsegmente Axle elements may be formed, for example, as metal rods. However, in order to keep the weight of the Rollbehangs as low as possible in this area, it is advantageous if at least a subset of the axle elements of a Rollbehangs are made of optionally fiber-reinforced plastic.

The row-connected curtain segments of the roll curtain according to the invention can rest against each other in the least possible distance if at least a subset of the curtain segments have a rectangular outer contour in plan view.

In order to prevent penetration between the curtain segments adjacent to one another in a row, it is advantageous if the transverse sides of the curtain segments arranged in a row of segments preferably abut each other without spacing.

The curtain segments of the roll curtain according to the invention can be produced with a low weight and a reduced cost of materials when the frame-shaped Behangsegmente define at least one frame opening.

In this case, an embodiment is preferred in which the frame opening of these Behangsegmente is hexagonal and / or diamond-shaped.

In the FIGS. 1 to 3 and the FIGS. 13 to 15 are various versions 1, 20 of a Rollbehangs shown in different views. The Rollbehänge 1, 20 are part of a Rolltoranlage, which serves 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 FIGS. 2 and 3 is shown as an example, the roller blinds 1, 20 each associated with a winding shaft 2, which is in drive connection with a manual or electric shaft drive. In order to design the winding shaft 2 as stable as possible, has in FIGS. 2 and 3 illustrated winding shaft 2 a non-circular and in particular an octagonal shaft cross-section.

As in the FIGS. 2 and 3 is also shown as an example, the Rollbehänge 1, 20 wound on the winding shaft 2 and configured unrollable from the winding shaft 2. The Rollbehänge 1, 20 are made of a plurality of Behangsegmenten 3; 21 formed, of which at least the subset of Behangsegmenten 3 shown here; 21 are designed similar or identical shape. The Behangsegmente 3; 21 in the FIGS. 1 to 3 and the FIGS. 11 to 15 Rollbehänge shown 1, 20 are connected to each other in segment rows 4. The segment rows 4 are oriented in the longitudinal direction of the winding shaft 2. In this case, each provided in a segment row 4 Behangsegmente 3; 21 rigid and the Behangsegmente 3; 21 of each segment row 4 with the Behangsegmenten 3; 21 adjacent segment rows 4 pivotally connected to each other about an oriented in the longitudinal direction of the winding shaft 2 pivot axis.

Since the roll hangers 1, 20 shown here do not consist of solid bars - but essentially of the area-shaped curtain segments 3; 21 are formed, and there these Behangsegmente 3; 21 can be made of any suitable material that is sufficiently stable and preferably light at the same time, the roll hangers 1, 20 even in larger dimensions can still be performed comparatively easily. Since the Rollbehänge 1, 20 of a plurality of flat Behangsegmente 3; 21 are formed, damage and deformations of the Rollbehänge 1, 20 can also be retrofitted even by replacing individual deformed Behangsegmente 3; 21 in the roll hanging 1 or 20 exchange. The adjacent Behangsegmente 3; 21 of each segment row 4 are connected to each other via at least one connector 5. For this purpose, each one of two adjacent Behangsegmenten 3; 21 at least one outwardly facing connecting pin 6; 26, which in an associated and inwardly facing connection opening 7; 27 of this connector 5 in the adjacent Behangsegment 3; 21 of the respective segment row 4 is held. As if from a closer look at the FIGS. 4, 5 and 7 as well as the FIGS. 11 to 20 becomes clear, the connecting pin 6 engages; 26 of each connector 5 in the associated connection opening 7; 27 of this connector 5 a.

As seen from the page views in FIG. 3 as well as in the FIGS. 13 to 15 becomes clear, the Behangsegmente 3; 21 on its flat sides on the shaft circumference of the winding shaft 2 approximated curved cross-sectional shape. By this curved cross-sectional shape, a space-saving rolling of Rollbehangs 1, 20 is promoted on the winding shaft 2. Assign the hanging segments 3; 21 of the Rollbehänge 1, 20 in the use position with its convex curved flat side to the outside, the Rollbehang 1, 20 at this, by the curved flat sides of Behangsegmente 3; 21 formed outside even greater pressure forces to withstand.

At least the subset of the roller hangings 1, 20 forming Behangsegmente 3; 21 is formed like a frame. The Behangsegmente 3; 21 of the roll hangers 1, 20 shown here can be made of any suitable material which is light and at the same time sufficiently stable. However, preference is given to an embodiment in which the curtain segment 3; 21 are made of plastic and in particular of fiber-reinforced plastic.

So that each one segment row 4 forming Behangsegmente 3; 21 of the in the FIGS. 1 to 3 shown Rollbehangs 1 can be rigidly connected to each other via the connectors 5 provided between them, the provided between the adjacent Behangsegmenten 3 Rollbehangs 1 connector 5 each have a connection opening 7 with non-circular clear opening cross-section in which the shape-adapted non-circular connection pin 6 is held.

From a close look at the FIGS. 1 . 2 . 4, 6 and 8 to 10 It is clear that protrude in adjacent Behangsegmenten 3 of each segment row 4 of Rollbehangs 1 pairwise associated and oriented in the longitudinal direction of the winding shaft 2 axle stub 9. Here, the pivot axis between adjacent rows of segments 4 forming stub axle pairs are each rotatably mounted in stub axle openings 10 on a stub axle counterpart 11, which stub axle counterparts 11 protrude to the Behangsegmenten 3 of each adjacent segment row 4. This stub axle counterparts 11 can be rigidly and preferably integrally connected to their associated curtain segment 3. But to a particularly good roll up and unrollability of Rollbehangs 1 ensure that is in the FIGS. 4 and 6 embodiment illustrated in detail, in which the corresponding stub axle counterpart 11 is held at its associated hanging segment 3 about an axis of rotation 12, which axis of rotation 12 is provided on the relevant Behangsegment 3.

From a comparison of FIGS. 4 and 6 It is clear that each stub axle counterpart 11 is formed at least in two parts and has a first coupling piece 13 and a second coupling piece 14, each carrying an opening portion 15, 16 of a stub axle pair associated stub openings 10. The coupling pieces 13, 14 are pivotally connected to one another at one pair of their opposite coupling piece ends via a living hinge 19 and may be connected to each other at the other pair of opposite coupling piece ends and preferably latched together. For this purpose, a latching pin 17 is provided on one of the opposite coupling piece ends, which engages in a latching opening 18 of the stub axle counterpart 11 latching.

The Behangsegmente 3 of Rollbehangs 1 have a frame or spectacle-shaped outer contour. At least the subset shown here Behangsegmente 3 has in the region of a longitudinal direction of the winding shaft 2 oriented longitudinal side of each of these Behangsegmente 3 the stub axle counterpart 11 and on one narrow side of both sides provided narrow sides of this Behangsegmentes 3, the connecting pin 6 and on the opposite narrow side of this Behangsegmentes 3, the connection opening. 7

As seen from the side view in FIG. 3 becomes clear, the Behangsegmente 3 on their flat sides on the shaft circumference of the winding shaft 2 approximate curved cross-sectional shape. By this curved cross-sectional shape, a space-saving rolling of Rollbehangs 1 on the winding shaft 2 is favored.

At least the subset of the curtain 1 forming Behangsegmente 3 shown here is frame-shaped and has a spectacle-shaped outer contour. The Behangsegmente 3 of Rollbehangs 1, 20 shown here can be made of any suitable material that is light and at the same time sufficiently stable. However, preference is given to an embodiment in which the curtain segments 3 shown here are made of plastic and in particular of fiber-reinforced plastic.

At least the subset shown here Behangsegmente 3 has in the longitudinal direction of the winding shaft 2 oriented longitudinal side of each of these Behangsegmente 3 the stub axle counterpart 11 and on one narrow side of both sides provided narrow sides of this Behangsegments 3, the connecting pin 6 and on the opposite narrow side of this Behangsegmentes 3, the connection opening 7 of the connectors 5. On the opposite side of the axle stub 11 and in particular on the narrow sides of each of these Behangsegmente 3 each one of the stub axle 9 is provided in an approximated to the stub axle counterpart 11 opposite longitudinal side portion.

While the Behangsegmente 3 of the in the FIGS. 1 to 3 shown Rollbehangs 1 are formed so that their molded stub axle pairs between the pivot axes form adjacent rows of segments 4 are in the in the FIGS. 11 to 15 Rollbehang 20 shown the Behangsegmente 21 adjacent rows of segments 4 each connected via a common axis element 22, which preferably extends over the entire width of the Rollbehangs 20. These, adjacent segment rows 4 interconnecting axle elements 22 are rod-shaped. The axle elements 22 of the in the FIGS. 11 to 15 Rollbehangs shown are guided in axle guides 23, 24, which are integrally formed on the mutually facing longitudinal sides of Behangsegmente 21 adjacent rows of segments 4 Rollbehangs 20.

In order to be able to form at least a subset of the drapery segments 21 forming the roll curtain 20, the drape segments 21 of adjacent segment rows 4 have axial guides 23, 24 complementary to their longitudinal sides such 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 segment row 4 such that these axle guides 23, 24 are aligned with each other. By the mutually aligned axle guides can then be the adjacent segment rows 4 articulated interconnecting and serving as a pivot axis between these rows of segments 4 axle element 22 inserted.

From a comparison of FIGS. 11 to 15 on the one hand and the FIGS. 16 to 20 On the other hand, it can be seen that the curtain segment 21 connected via a common axle element 22 has first axle guides 23 spaced from each other on its first longitudinal side and at its opposite second Longitudinal carry at least one second axle guide 24, and at the distance of the first axle guides 23, a recess 25 is formed, in which recess 25, the at least one second axle guide 24 of an opposite Behangsegmentes 21 of the adjacent segment row 4 engages such that the first axle guides 23 of in the one segment row 4 provided Behangsegmente 21 with the second axle guides 24 of the opposite Behangsegmente 21 of the adjacent segment row 4 are aligned.

In order that the axle guides 23, 24 of the hanging curtain 20 forming Behangsegmente 21 interlock such that forms the flat Rollbehang, the first axle guides 23 of each of these Behangsegmente 21 compared to the at least one second axle guide 24 each half the longitudinal extent in the longitudinal direction of the axle 22 on.

From a comparison of FIGS. 16 to 20 It is clear that at least one outwardly facing connecting pin 26 protrudes at one transverse side of each of these Behangsegmente 21, which is arranged at a distance from the corners between this transverse side and the longitudinal sides of this Behangsegmentes 21. The laterally integrally formed on the hanging segment 21 and engaging in the connecting opening 27 on adjacent hanging segment 21 connecting pin 26 cooperates with the respective pivot axis forming axle elements 22 of the Rollbehangs 20 such that the rows of segments 4 of the Rollbehangs 20 about the pivot axis forming axle elements 22 are deformable , without that Behangsegmente 21 adjacent to each other in a segment row 4 can pivot to each other.

Trained as a plug-axle axle elements 22 of the Rollbehangs 20 can be made of metal or other suitable recyclable material. In order to design the roll curtain 20 with the lowest possible weight, however, a preferred embodiment provides that these shaft 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 bounded by a round enveloping circle.

From a comparison of FIGS. 16, 17 and 19 It can be seen that the hanging curtain 20 forming Behangsegmente 21 each have a rectangular outer contour in plan view. In this case, the transverse sides of the arranged in a row segment Behangsegmente 21 each abut each other without spacing, which is meant as a distance here, a distance between the Behangsegmenten 21, in which a person can not intervene with his fingers.

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

The oriented in the vertical direction longitudinal sides of the Rollbehänge 1, 20 are guided in sliding guides not shown here, which slide guides each carry a guide groove. In order to be able to produce the roll curtain when required also in different widths, at least a subset of the in the sliding guides engaging Behangsegmente have a reduced width. It is possible in a modular Rollbehang system to provide executed in different pitches Behangsegmente that can be mounted on the vertically oriented longitudinal sides of the Rollbehangs.
