Definitions

  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the insert elements are designed in the form of plates.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • locking webs or similar locking means can 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • roller blind 1 of a roller grille system not shown here is shown.
  • 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.

  • 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.
  • 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.
