Definitions

  • the invention relates to a blind, in particular an improved Roman blind.
  • a conventional Roman blind comprises an top rail for attachment to a ceiling, a blind panel which is attached to the top rail and cords which are fitted to the top rail and attached to the blind fabric and cooperate in order to control the upward and downward movement of the blind fabric.
  • the blind panel is composed of several, mutually connected parallel sections. Usually, a substantially horizontally oriented folding rod and one or more eyelets for guiding the cords are provided between every two adjacent sections.
  • the sections When (a lower part of) the blind fabric is moved in an upward direction, the sections will successively be deformed, from an extended state to a more or less pleat-like or looplike state, in which the folding bars will be positioned against each other or near each other.
  • a reverse movement will take place and the sections will unfold substantially completely in the downward direction.
  • the cords are usually positioned in pairs, behind the blind, viewed from the normal viewing side of the blind, and are therefore hardly visible from the viewing side, if at all.
  • the invention provides a blind of the type mentioned in the preamble, comprising: a top rail, at least one first blind panel attached to the top rail and comprising several mutually connected parallel sections, wherein several cord-guiding elements are attached to the blind panel between adjacent sections, several cords attached to the top rail and a bottom parallel section, wherein each cord cooperates with at least one cord-guiding element for raising and lowering the first blind panel, at least one second blind panel which is attached to the top rail and the cords and folded in plisse, wherein through-openings are provided in the second blind panel for passing through the abovementioned cords.
  • the first blind panel in this case preferably forms a Roman blind, also referred to as a Roman shade.
  • the second blind panel By enclosing the originally freely hanging cord parts of the first blind panel by means of an applied second blind panel, loop formation can be prevented, thus minimizing the risk of entrapment and suffocation by the blind.
  • the second blind panel By using the second blind panel, a double-layered (laminated) blind is created, wherein the first blind panel usually functions as (an interior-facing) viewing side of the blind and the second blind part in particular functions as a safety feature for protecting the cords in a safe, practical and esthetically pleasing manner that loop formation of the cords which might lead to suffocation can no longer occur.
  • the second blind panel is folded in plisse and this gives it a typical zigzag or accordion structure, formed by mutually pivotably connected lamellas (or shutters).
  • This plisse structure can be folded out and folded up. Due to the fact that both blind panels are connected to the cords, both blind panels will simultaneously carry out the same upward or downward movement.
  • the through-openings provided in the lamellas of the second blind panel de facto form several, preferably substantially mutually parallel through- passages through which the cords are respectively guided.
  • the lamellas of the second blind panel In a pulled-up (folded-up) position of the blind, the lamellas of the second blind panel will usually be positioned substantially on top of each other and against each other, as a result of which the through-passages formed by the through-openings enclose the (unwound) cord parts substantially completely, thus de facto creating a closed duct.
  • the lamellas of the second blind panel will usually not lie against each other, as a result of which the through-passages formed by the through-openings will be of a more open kind and thus the (unwound) cord parts will be visible.
  • the distance between adjacent through-openings i.e. situated one above the other
  • the distance between adjacent through-openings will be limited to at most 5 centimeters, which will only allow microloops to form which cannot cause an individual to suffocate.
  • Each cord is attached to both the first blind panel and the second blind panel, as a result of which each cord can be used to operate both blind panels.
  • the sections of the first blind panel preferably extend in a substantially horizontal direction, with the sections being connected to each other along the substantially horizontal longitudinal edges.
  • This connection is usually an integral connection as the blind panel is often produced from a single layer of material.
  • the transition between adjacent sections is usually formed by an intermediate pleat in which a folding rod can be accommodated. Due to its dead weight, the folding rod ensures that the first blind panel is folded up and unfolded in a controlled manner.
  • the folding rod is preferably made from fiber material or aluminum.
  • the intermediate pleat and/or the folding rod are attached to one or more cord-guiding elements for guiding the cords.
  • the cord-guiding elements are in this case preferably each formed by a ring or eyelet through which one of the cords is guided.
  • the rings or eyelets do not necessarily have to be round, but may also have a different shape, such as a heart shape. It is often advantageous if the rings or eyelets are interrupted and if they are also made from a slightly flexible material.
  • the interruption in the cord-guiding element makes it possible to introduce a cord into the cord-guiding element by means of a lateral movement, with the cord passing through the cord-guiding element which can significantly improve, facilitate and shorten installation of the cord-guiding elements. Due to the slightly resilient action of the cord-guiding element, the interruption can be made so small that the cord cannot easily be removed therefrom and to outside the cord- guiding element, as a result of which the cord would be uncoupled.
  • the cords can move freely through the cord-guiding elements.
  • the cords are usually fixedly connected to or near an underside of the first blind panel.
  • the blind comprises a bottom bar, with the first blind panel and the cords being attached to the bottom bar.
  • the second blind panel is also attached to the bottom bar, thus ensuring simultaneous and even displacement of the two blind panels. Due to its dead weight, the bottom bar also ensures that the two blind panels are unfolded and folded up in a controlled manner.
  • both blind panels to each have their own bottom bar.
  • the blind comprises several cords in order to be able to fold up and unfold the blind panels in a stable and upright, balanced manner.
  • the cords used are attached to the top rail, also referred to as top bar.
  • the top bar is provided with one or more axially rotatable cord spools, also referred to as cord drums, for winding up and unwinding the cords.
  • the at least one, usually substantially cylindrical, cord spool By rotating the at least one, usually substantially cylindrical, cord spool, the effective length of the (unwound) cord parts can be determined and thus the degree to which the blind panels are folded up and unfolded.
  • the cord spool will be enclosed at least partly and often substantially completely in the top bar, or at least a housing thereof.
  • Making the at least one cord spool rotate can be effected manually, for example by means of an operating cord or operating pendant coupled to the at least one cord spool, and/or automated by coupling the at least one cord spool to or by providing it with at least one electric motor.
  • the electric motor can optionally be controlled wirelessly. If several cord spools are used and each cord cooperates with its own cord spool, it is then conceivable to mechanically couple the cord spools to each other so that both cord spools can rotate simultaneously and evenly, which benefits the raising and lowering of the blind in an upright manner.
  • an operating pendant it is advantageous if this is coupled in a detachable manner, preferably using magnetism, to a drive rod and/or a cord spool, as a result of which the operating pendant will be uncoupled when it exceeds a predefined force, thus making it possible to substantially prevent dangerous situations.
  • the maximum distance between adjacent through- openings of the second blind panel is 5 centimeters. This distance is more than sufficiently small to prevent the dangerous formation of loops.
  • Each through-opening is preferably situated substantially non-centrally with respect to the longitudinal axis of a lamella of the second blind panel in order to be able to form a substantially cylindrical through-passage for a (single) cord - in the folded-up position of the second blind panel.
  • the particular advantage of the non-central positioning it that, on one side, slightly larger, yet harmless loops are created between each cord and two adjacent lamellas of the first blind panel are created in order to facilitate attachment of the cord-guiding elements of the first blind panel to the cords. In this case, the non-central positioning is thus chosen such that the larger loop formation occurs on a side of the second blind panel facing the first blind panel.
  • each lamella is provided with an x number of through-openings for forming an x number of through-openings, with x normally being equal to 2.
  • the maximum center-to-center distance between two successive through-openings is thus preferably substantially equal to twice the width of the lamella of the second blind panel.
  • Typical lamella widths of known pleated blinds are 25 millimeters and 45 millimeters. From a practical point of view, it is preferable to use a known pleated blind, more preferably having a relatively limited lamella width, as second blind panel, as a result of which the maximum distance between successive through-openings is 5 centimeters, in particular 4.5 centimeters. More preferably, this maximum distance is 3 centimeters, in particular 2.5 centimeters.
  • the invention also relates to a first blind panel for use in a blind as claimed in the invention.
  • the invention also relates to a second blind panel for use in a blind as claimed in the invention.
  • the invention furthermore relates to a top rail (top bar) for use with a blind as claimed in the invention, in which the top rail is configured so as to (simultaneously) couple both the first blind panel and the second blind panel. Coupling of the blind panels to the top rail may be effected by means of hook and loop fastener, one or more brackets, one or more profiles, clips, etc. Further advantages and variant embodiments of the abovementioned components have already been described in detail above. The invention will be explained with reference to the following non-limiting exemplary embodiments illustrated in the figures, in which:
  • Fig. 1 a shows a cross section of a blind as claimed in the invention in an unfolded position
  • Fig. lb shows a cross section of the blind from Fig. la in a folded-up position
  • Fig. 2 shows a perspective view of a part of the blind from Figs, la and lb, and
  • Fig. 3 shows a top view of a part of an unfolded pleated blind for use with a blind from Figs. la-2.
  • Fig. 1 a shows a cross section of a blind 1 as claimed in the invention in an unfolded position.
  • the blind 1 comprises a Roman blind panel 2 which also forms the normal viewing side of the blind 1.
  • the Roman blind panel 2 is connected to a top rail 3 configured to be attached to a ceiling.
  • the Roman blind panel 2 comprises several parallel sections 2a in which adjacent sections 2a are integrally connected to each other via a pleat 2b.
  • the pleats 2b in this case form a receiving space for a folding rod 4, in order to ensure the Roman blind panel 2 is suspended in a taut and controlled manner.
  • Each pleat 2b and/or folding rod 4 accommodated therein is connected to two spaced- apart rings 5 for passing through two cords 6.
  • the cords 6 extend from a cord spool 7 incorporated in the top rail 3 to a bottom bar 8 which is connected to the blind panel 2, each cord 6 being connected to both the cord spool 7 and the bottom bar 8.
  • H manual
  • M automated
  • the cords can be wound up or unwound, depending on the direction of rotation of the cord spool 7, as a result of which the Roman blind panel 2 can be pulled up or lowered.
  • the bottom bar 8 will be moved in an upward direction with the aid of the cords 6, in which case the cords 6 will slide through the rings 5 and a pleat will be formed in the bottom section 2a.
  • the bottom bar 8 will successively lift the folding bars 4 along to form further pleats in the top sections 2a of the Roman blind panel 2 (see Fig. lb).
  • Roman blinds are relatively popular, the known Roman blinds have the drawback that the cords can form relatively dangerous loops which may result in infants suffocating.
  • the cords 6 of the blind 1 are at least partly protected by an additional blind panel formed by a pleated blind 9.
  • the pleated blind 9 is composed of several lamellas 9a which are mutually alternately connected to each other, resulting in an accordion structure (see Fig. 2). Each lamella 9a is provided with two through-openings 9b for the passage of the respective cords 6.
  • the through-openings 9b situated above one another form a substantially closed through-passage, in which the cords 6 are (or a part of the cords 6 which protrudes with respect to the top rail 3 is) enclosed substantially completely by the pleated blind 9.
  • the through-openings 9b situated above one another form an open through-passage, in which the cords 6 are (or a part of the cords 6 which protrudes with respect to the top rail 3 is) partly enclosed by the pleated blind 9.
  • the lamella width D is 4.5 centimeters (see Fig. 3).
  • the pleated blind 9 is connected to the top rail 3 and, at the bottom, it is provided with a bottom bar 10 to ensure the pleated blind 9 hangs in a taut manner and can be moved in a controlled manner.
  • the bottom bar 10 and/or a bottom part of the pleated blind 9 is attached to the cords 6 in order to be able to operate the pleated blind 9. Due to the fact that the Roman blind 2 and the pleated blind 9 cooperate and are also connected to the (common) cords 6, both blind panels 2, 9 are operated simultaneously.
  • the dimensions of the pleated blind are preferably slightly smaller than the dimensions of the Roman blind 2, so that only the Roman blind 2 is visible when the blind 1 is normally viewed from the front. It will be clear that the invention is not limited to the exemplary embodiments illustrated and described here, but that numerous variants are possible without departing from the scope of the attached claims, which variants are obvious to someone skilled in the art.
