Description

The invention relates to a roller blind with a winding shaft onto which the roller blind can be wound and from which the roller blind can be unrolled.

From the EP 3 521 544 A1 a roller blind of the type mentioned is already known. The previously known roller blind 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 drive-connected to a shaft drive, is assigned to the previously known roller blind. The roller blind can be wound onto the winding shaft and unrolled from the winding shaft and is formed from a plurality of blind segments which are connected to one another in rows of segments. The rows of segments formed from blind segments connected to one another in rows are oriented in the longitudinal direction of the winding shaft. The curtain segments provided in a segment row are rigid and the curtain segments of each segment row are connected to the curtain segments of adjacent segment rows so that they can pivot about a pivot axis oriented in the longitudinal direction of the winding shaft. Since the previously known roller blind is not made up of solid rods, but essentially from flat curtain segments, and since these blind segments can be made of any suitable material that is sufficiently stable and at the same time comparatively light, the previously known roller blind can still be comparatively large even in larger dimensions easily executed and its hanging segments made of plastic and in particular made of a fiber-reinforced plastic. In order to further reduce the weight of the previously known roller blind and its blind segments, at least a subset of the blind segments of the previously known roller blind are designed in the shape of a frame and in particular in the shape of spectacles, with these blind segments each delimiting at least the frame opening.

In certain areas of application, it may be desirable to use a roller shutter, which tightly closes the building opening to be secured if necessary, instead of a roller grille having a large number of frame openings. It can also be desirable to individualize the rolling grille or roller shutter with a multicolored design, an advertising inscription or also with an image representation on the visible side. Furthermore, it is conceivable that the frame openings of the curtain segments should be at least reduced in the lower area of the roller blind in order to make it difficult or impossible for mice, rats or martens to access the premises behind.

There is therefore the task of creating a roller blind of the type mentioned at the outset, which can optionally also be customized or additionally secured at a later date.

The solution to this problem according to the invention consists in the roller blind of the type mentioned in particular in that at least one subset of the frame-shaped blind segments is assigned at least one insert element, which insert element can be inserted into the at least one frame opening of the blind segment assigned to it and can be fixed to this blind segment. and that the insertion elements the frame opening of the associated, reduce or close the frame-shaped curtain segments.

The roller blind according to the invention also has a winding shaft onto which the roller blind can be wound and from which the roller blind can be unrolled. The roller blind according to the invention can be formed from blind segments which are connected to one another in rows of segments which are oriented in the longitudinal direction of the winding shaft. While the curtain segments provided in a row of segments can be rigidly connected or connected to one another, these curtain segments of each row of segments can be connected to the curtain segments of adjacent rows of segments so that they can pivot about a pivot axis oriented in the longitudinal direction of the winding shaft.

At least a subset of the blind segments forming the roller blind is designed in the shape of a frame and delimits at least one frame opening. At least one subset of the frame-shaped curtain segments is assigned at least one insert element, which insert element can be inserted into the at least one frame opening of the curtain segment assigned to it and can be releasably or non-releasably fixed to this curtain segment. The insert element can be inserted into the at least one frame opening of the hanging segment assigned to it in such a way that these insert elements reduce or close the frame openings of the assigned, frame-shaped hanging segments. Since the insert elements that can be inserted and fixed in the frame openings reduce or close the frame openings of the associated, frame-shaped blind segments, reaching through the blind according to the invention or the penetration of leaves, mice, rats, martens or the like is made more difficult or more difficult, at least in this partial area of the blind even impossible made. Since the insert elements are designed separately from the blind segments assigned to them, the insert elements can also be produced or configured in colors that differ from the blind segments. The roller blind according to the invention can also be subsequently individualized or adapted to the environment of the structure secured in this way due to the insert elements that have a different color from the blind segments. If a visible advertising inscription or, in addition or instead, an image is desired on the roller blind, it is possible to apply partial areas of the desired advertising inscription or image to the insert elements of this roller blind, so that when the roller blind and its insert elements are viewed together, a pixel-like advertising inscription or image can be seen will.

The insert elements can be made of any suitable material. However, so that the insert elements do not additionally burden the weight of the roller blind excessively, it is advantageous if the insert elements are each made of plastic and/or are designed as plastic injection molded parts. Such insert elements made of plastic and designed in particular as a plastic injection molded part can be produced inexpensively. However, it is also possible for insert elements to consist of metal, for example aluminum and/or stainless steel.

In order to close the frame openings as completely as possible in at least a subset of the curtain segments, it can be expedient if the insert elements are designed in the form of plates.

In various applications it can be advantageous if the insert elements have a lattice or mesh structure at least in a partial area. This grid or Net structure can also be formed by a large number of perforations in the insert element, which is plate-shaped per se. This lattice or net structure ensures good ventilation of the rooms behind, also through the roller blind, without leaves, dirt particles, rodents or other things being able to penetrate through the frame openings in the blind segments.

In order to be able to fix the insert elements securely and firmly on the curtain segment assigned to them, it is advantageous if the frame-shaped curtain segments have, at least in sections, a triangular or cam-shaped cross-section in their edge region surrounding a frame opening that tapers in the direction of the frame opening. This cross-section of the curtain segments, which tapers in the direction of the frame opening, in their edge region surrounding a frame opening, promotes a firm and secure hold of the insert elements in the curtain segment assigned to them.

In order to counteract the slipping of the insert elements fixed to the associated curtain segment, it is advantageous if the insert elements rest on at least two of their opposite narrow edges against the edge region of the associated curtain segment that surrounds a frame opening.

A secure and in particular a non-slip fixation of the insert elements on their associated curtain segments is favored if the insert elements are formed on the at least two narrow edges resting on the associated curtain segment complementary to the adjacent marginal partial area of the associated curtain segment.

In order to be able to fix the insert elements securely and either non-detachably or also easily detachably to the curtain segments assigned to them, it is advantageous if locking webs or similar locking means are provided on the insert elements, which are designed for detachably or non-detachably fixing the insert elements.

An advantageous embodiment according to the invention provides that the locking webs or similar locking means engage behind the edge region surrounding the frame opening of the associated blind segment in the locking position.

A particularly advantageous further development according to the invention provides that the insertion elements assigned to a blind segment are each formed in at least two parts. The insert elements may comprise at least a first element part and a second element part. The insert elements assigned to a curtain segment can have an internal element part and an external element part. Such an at least two-part insert element can terminate almost flush and almost in one plane with the edge regions of the blind segment bordering the frame opening. Such an embodiment formed from at least two element parts gives the impression that the curtain segment and its associated insertion element practically form a closed section of the roller blind without this embodiment excessively increasing the weight of the roller blind.

With such an at least two-part design of the insert element, it can be advantageous if each of the latching webs or similar latching means protruding on one element part interacts with an associated counter-latching means on the other element part of an insert element. It is also possible, however, for locking webs or similar locking means to protrude both on the inner and the outer element part, which are "arranged with a gap" in the locking position in such a way that these locking webs or similar locking means of the two element parts each cover the edge area of the frame opening of the associated curtain segment can reach out from behind opposite flat sides of the curtain segment.

A firm hold of the at least two-part insert element and an attractive design of the roller blind according to the invention is favored if the element parts of an insert element which are latched together clamp the associated blind segment between them in the area of the frame opening.

The frame-shaped curtain segment can be designed in such a way that this curtain segment has a spectacle-shaped contour. However, it is also possible for the curtain segment to have an essentially rectangular outer contour. A preferred embodiment according to the invention provides that the frame opening of the frame-shaped hanging segments is rhombic. Due to the diamond-shaped design of the frame opening, the frame-shaped blind segments can still be made sufficiently stable in their corner areas, even if these blind segments are made of a non-metallic material, in particular plastic.

In one embodiment of the roller blind, it is provided that at least a subset of the blind segments consists of a non-metallic material, in particular plastic, and/or is flat.

In one embodiment of the roller blind, it is provided that the roller blind is designed as a roller grille. At least a subset of the curtain segments, in particular the frame-shaped curtain segments, can comprise rods, in particular made of metal, for example aluminum or stainless steel, or consist of rods, in particular made of metal, for example aluminum or stainless steel.

The rods can be solid or hollow. Furthermore, the bars can be connected to form a frame. The rods can delimit a frame opening of the respective curtain segment. In this way, the roller blind can have an appearance that corresponds to the appearance of a conventional roller grille, with the frame openings of the frame-shaped blind segments, which may include rods, being reduced in size or closed by the use of insert elements. The insertion elements can be attached to rods of the blind segments.

So that the blind can be rolled up in a space-saving manner when it is wound onto the winding shaft and so that the blind segments of the blind according to the invention are well secured, in particular against pressure being applied over a large area, it is advantageous if the blind segments of the blind have a circular cross-section and if the insert elements and in particular their element parts have a complementary cross-sectional shape.

Further developments according to the invention result from the following description of the figures in conjunction with the claims and the drawing. The invention is described in more detail below using a preferred exemplary embodiment.

In the Figures 1 to 3 the roller blind 1 of a roller grille system not shown here is shown. With the help of such a rolling grille system and its roller blind 1 shown here, for example, a window or door opening, an underground car park exit, a house entrance or similar opening of a building can be closed if necessary and secured against unauthorized access. To open or close the building opening, the roller blind 1 can be rolled onto a rotatably drivable winding shaft or unwound from this winding shaft. The winding shaft can be drive-connected to a manual or motorized shaft drive.

The roller blind 1 is formed from a plurality of blind segments 2, of which at least the subset shown here of blind segments 2 are designed in the same way or identical in shape. The curtain segments 2 in the Figures 1 to 3 shown blinds 1 are connected in segment rows 3 together. The segment rows 3 are oriented in the longitudinal direction of the winding shaft, not shown here. The curtain segments 2 provided in a segment row 3 are rigid and the curtain segments 2 of each segment row 3 are pivotably connected to the curtain segments 2 of adjacent segment rows 3 about a pivot axis oriented in the longitudinal direction of the winding shaft.

As seen from the side views in the Figures 3 , 7 , 11 and 13 As can be seen, the curtain segments 2 have a curved cross-sectional shape on their flat sides that approximates the circumference of the winding shaft. This curved cross-sectional shape promotes a space-saving rolling up of the roller blind 1 onto the winding shaft. If the blind segments 2 of the blind 1 point outwards in the position of use with their convexly curved flat side, the blind 1 can also withstand greater compressive forces on this outside formed by the curved flat sides of the blind segments 2 .

At least the subset shown here of the blind segments 2 forming the roller blind 1 is designed in the shape of a frame, with each of the blind segments 2 delimiting a frame opening 4 in each case. Since the roller blind 1 is not made up of solid rods, but essentially from the flat curtain segments 2, and since the blind segments 2 can be made of any suitable material that is sufficiently stable and at the same time preferably light, the roller blind 1 can also be larger dimensions can still be carried out comparatively easily. An embodiment is preferred in which at least a subset of the Behangsegmente 2 of the roller blind 1 is made of plastic and in particular made of fiber-reinforced plastic.

The adjacent curtain segments 2 of each segment row 3 are each connected to one another with a plug connection 5 . For this purpose, one of two adjacent hanging segments 2 has at least one outwardly pointing connecting pin 5 which is held in an associated and inwardly pointing connection opening 15 of the plug connection in the adjacent segment 2 of the respective row 3 of segments. The connecting pin 5 of each plug-in connection engages in the associated connection opening 15 of this plug-in connection on the adjacent hanging segment 2 . In order to make this plug-in connection between the hanging segments 2 arranged in a segment row 3 rigid, the non-round connecting pin 5 can be held in a complementary connecting opening 15 with a non-round clear opening cross section.

At the in the Figures 1 to 3 shown roller blind 1, the curtain segments 2 adjacent rows of segments 3 are each connected via a common axis element, not shown here, which preferably extends over the entire width of the roller blind 1. These axle elements, which connect adjacent rows of segments 3 to one another, are rod-shaped. The axis elements in the Figures 1 to 3 The blinds 1 shown are guided in axle guides 6, 7, which are formed on the longitudinal sides of the blind segments 2 of adjacent rows of segments 3 of the blind 1 that face one another. In order to be able to design at least a subset of the blind segments 2 forming the roller blind 1 in the same way and in particular with the same shape, the blind segments 2 of adjacent rows of segments 3 have complementary axis guides 6, 7 on their long sides in such a way that at least one, on one long side of each of these Curtain segments 2 provided axis guide 7 engages in a recess 8 between two axis guides 6 on at least one curtain segment 2 of the adjacent row of segments 3 in such a way that these axis guides 6, 7 are aligned with one another. Due to the aligned axle guides 6, 7, the axle element which connects the adjacent segment rows 3 to one another in an articulated manner and serves as a pivot axis between these segment rows 3 can then be inserted.

From the Figures 1 and 2 it becomes clear that the curtain segments 2 connected via a common axle element carry spaced-apart first axle guides 6 on their first longitudinal side and at least one second axle guide 7 on their opposite second longitudinal side, and that the recess 8 is formed at the distance from the first axle guides 6, into which Recess 8 which engages at least one second axis guide 7 of an opposite curtain segment 2 of the adjacent segment row 3 in such a way that the first axis guides 6 of the curtain segments provided in one segment row 3 are aligned with the second axis guides 7 of the opposite curtain segments 2 of the adjacent segment row 3.

So that the axis guides 6, 7 of the blind segments 2 forming the roller blind 1 engage in one another in such a way that the flat roller blind 1 is formed, the first axis guides 6 of each of these blind segments 2 have half the longitudinal extension in the longitudinal direction of the blind compared to its at least one second axis guide 7 Axle element 6 on. The connecting pin 5, which is formed laterally on the blind segment 2 and engages in the connection opening on the adjacent blind segment 2, interacts with the axis elements of the roller blind 1, each of which forms a pivot axis, in such a way that the rows of segments 3 of the roller blind 1 can be deformed about the axis elements forming the pivot axis, without the curtain segments 2 lying against one another in a segment row 3 can pivot towards one another.

In various areas of application is instead of in the Figures 1 to 3 illustrated and designed as a rolling grille roller blind 1 preferred a roller shutter. It can also be desirable to individualize the rolling grille or roller shutter with a multi-colored design, with an advertising inscription or also with a picture representation on the visible side. It is also conceivable that the frame openings 4 should only be reduced in size in a partial area and preferably in the lower area of the roller blind 1 in order to make it difficult or impossible for leaves, rodents or the like to access the premises located behind.

As from a comparison of Figures 3, 4 , 7 and 11 to 14 As can be seen, at least a subset of the frame-shaped blind segments 2 is assigned an insertion element 9, which insert element 9 can be inserted into the at least one frame opening 4 of the blind segment 2 assigned to it. In doing so, the insert elements 9 close or at least reduce the size of the frame openings 4 of the associated, frame-shaped curtain segments 2.

From the Figures 15 and 20 it can be seen that the insert elements 9, which can each be made of plastic or designed as a plastic injection molded part, are designed in the form of plates. In addition or instead, it is possible for the insert elements 9 to have a lattice or mesh structure, at least in a partial area, which is not shown in any more detail here. This lattice or net structure can also be formed from a plurality of holes in the plate-shaped insert element 9 . This lattice or network structure of the insert elements 9 opens the frame opening 4 of the associated, frame-shaped curtain segments is reduced without the insert elements 9 preventing ventilation of the rooms behind them through the roller curtain 1 .

In figure 13 It is particularly easy to see that the frame-shaped curtain segments 2 in their edge region 14 surrounding a frame opening 4 at least partially have a cross-section that tapers in the direction of the frame opening 4 and is particularly triangular or cam-shaped. the end figure 13 It is also clearly visible that the insert elements 9 are in contact with at least two of their opposite narrow edges against the edge region 14 of the associated hanging segment 2 that surrounds a frame opening 4 . The insertion elements 9 on the at least two narrow edges resting on the associated curtain segment 2 are designed to be complementary to the adjacent partial area on the edge of the associated curtain segment 2 . In this way, a secure and non-slip fixation of the insert element 9 on the curtain segment 2 assigned to it is promoted.

From a synopsis of the Figures 11 to 14 it can be seen that the insertion elements 9 assigned to a curtain element 2 are each formed in at least two parts and have an inner element part 10 and an outer element part 11 . In this case, locking webs 12 or similar locking means protrude from the inner element part 9 , which in the locking position of the insert element 9 each interact with an associated counter-locking means 13 on the outer element part 10 of the insert element 9 . The element parts 10, 11 latched to one another clamp the associated hanging element 2 in the region of the frame opening 4 between them. This frame opening 4 of the frame-shaped formed hanging segments 2 is here in each case rhombus-shaped, so that the hanging segments 2 have a reinforced configuration in their corner areas.

The insert elements 9 can also be fixed in an easily detachable manner on the curtain segments assigned to them. In this way it is possible to redesign the roller blind by replacing at least individual insert elements 9 . In the embodiment shown here, however, the insert elements 9 are permanently fixed to the curtain segments assigned to them after they have been locked. The insertion elements 9 can only be detached from the frame opening of the hanging segment assigned to it with a great deal of force and the acceptance of damage to the insertion elements 9.

From the figures 7 , 11 and 13 it can be seen that the blind segments 2 of the roller blind 1 have a circular cross-section. As in the Figures 8 to 10 and 12 to 14 As can be seen, the insert elements 9 and in particular their element parts 10, 11 also have a complementary cross-sectional shape.

How from the Figures 15 and 16 As can be seen, the element parts 10, 11 of the insert elements 9 have a printable flat side on the visible side. An advertising inscription, a picture element or the like can thus be printed on the flat side of the element parts 10, 11 of the insert elements 9. An individualization of the roller blind 1 shown here is also possible in that the insert elements 9 are visibly designed differently from the blind segments 2 forming the roller blind 1 and, for example, have a recognizable different surface, a different material and/or a different color design.
