Definitions

  • This document relates to a cord device for window coverings and to window coverings comprising a cord device. Further, the present application relates to a child safety device for window coverings.
  • Colson et al. provide in U.S. Pat. No. 6,116,325 a break away operating cord system for retractable coverings for architectural openings such as windows, doors, arches or the like which includes a mounting plate to which an operating cord is attached and wherein the mounting plate is releasable from the remainder of the control system for the retractable covering allowing the operating cord to be separated from most of the covering to avoid injury to a child or infant whose head might be trapped within the closed operating cord loop.
  • Kollman et al. disclose in U.S. Patent No. 7,086,446 a cord connection device for roll-up shades having a coupling member that fits over a receptive member.
  • the body of the receptive member has a section configured to receive the coupling member in a manner to provide a connection such that when a selected force acts on a cord attached to the coupling member or the receptive member the coupling member will separate from the receptive member.
  • the body of the receptive member can have a second section configured to receive the coupling member in a manner to provide a connection such that the coupling member will not separate from the receptive member or can have a third section configured such that the coupling member will separate when a second selected force acts on the cord or can have all three sections.
  • a cord device and a child safety device, respectively, for a window covering comprising at least one cord for operating the window covering and at least one cord shroud, wherein the at least one cord is housed in the at least one cord shroud and the at least one cord shroud is designed to be attached to the window covering.
  • the cord device further comprises a plurality of loops formed on the at least one cord shroud and a plurality of first clips for coupling the at least one cord shroud to the window covering wherein each first clip of the plurality of first clips is attached to a loop of the plurality of loops on the at least one cord shroud. Each first clip of the plurality of first clips is also attached to a respective loop formed on the window covering.
  • the distance between two first clips attached to the at least one cord shroud and to the window covering should be such as hindering a child's head to pass underneath a cord between two first clips.
  • the distance between two first clips should e.g. not exceed 15 centimeters or about 6 inches.
  • the at least one cord shroud has the function of housing the otherwise exposed cord, thus further reducing the risk of injuries.
  • the at least one cord shroud may be, for example, a fabric tube.
  • the cord shroud may have alternating softer and harder sections. These sections may be formed by adequate yarns or/and an appropriate weaving technique. Alternatively, the cord shroud may have an accordion structure with periodical segments with bigger and smaller diameter that can contract upon pulling of the at least one cord.
  • the at least one cord shroud is provided with a plurality of loops. These loops are formed on the length of the at least one cord shroud.
  • the plurality of loops may, for example, be formed by stitching a ribbon to the at least one cord shroud at definite distances along the at least one cord shroud, or by loops woven into the shroud.
  • the loops may be rings of metal or fabric or similar suitable material (such as plastic materials) that are attached to the cord shroud, e.g. being singularly stitched onto the cord shroud.
  • the loops have the function to enable the coupling of the at least one cord shroud with the window covering.
  • the window covering may be provided with a number of loops.
  • One loop on the window covering is coupled to one loop on the at least one cord shroud by a first clip which may be a double clip.
  • the number of loops on the window covering must not be equal with the number of loops on the at least one cord shroud.
  • the distance between two loops on the window covering in a longitudinal direction has to be chosen such that a children's head may not fit through the opening creating the hazardeous loop (i.e. a cord section between two first clips), or such that it is in line with according standards.
  • one standard may relate to a distance of approx. 15 centimeters or approx. 6 inches, but higher or lower distances are possible.
  • a window covering comprising a panel of window covering material, at least one cord for operating the window covering and at least one cord shroud housing the at least one cord, wherein the at least one cord shroud is designed to be attached to the panel of window covering material.
  • the window covering also comprises at least one first clip, wherein the at least one cord shroud is coupled to the panel of window covering material by the at least one first clip.
  • the loops have the function to enable the coupling of the at least one cord shroud with the window covering.
  • the panel of window covering material may also be provided with a plurality of loops.
  • the at least one first clip is attached to the at least one loop of the plurality of loops on the at least one cord shroud and to the at least one loop of the plurality of loops on the panel of window covering material.
  • the window covering may further comprise a headrail to which a top edge of the window covering material is attached.
  • the window covering material also comprises a bottom edge to which a first end to which a first end of the at least one cord is attached.
  • Each first end of the at least one cord may be fixed to a second clip attached to a loop stitched on the panel of window covering material in proximity of the bottom edge.
  • the bottom edge of the panel of window covering material may have a bottomrail or rod.
  • the headrail may comprise at one of its side ends a cord block and release device.
  • a simple cord device for a window covering which enables an easy retrofitting of window coverings bearing at least one cord and loops on the window covering for lifting the same.
  • FIG. 1 A schematic side view of a window covering is shown in Fig. 1 . Here, only a panel of window covering material 1 is shown.
  • Window coverings often comprise a headrail, to which an upper edge of the panel of window covering material 1 is attached, and a bottomrail or rod.
  • the window covering is raised and lowered by operating at least one cord 2.
  • the cord is attached (not shown) in proximity of the bottom edge of the panel of window covering material 1 and runs up the back surface of the panel of window covering material 1 into the headrail.
  • the cord 2 that runs up the back surface of the panel of window covering material 1 is housed in a cord shroud 3.
  • the cord shroud 3 may be a fabric tube, but other suitable materials are possible and known to the person skilled in the art. In order to enable a smooth lifting of the window covering, the cord shroud 3 may have softer and harder segments or, as shown in fig. 1 , an accordion structure with periodical segments with bigger and smaller diameter.
  • a respective loop 4 is positioned, whereby all the loops 4 on the cord shroud 3 are in one line.
  • the loops on the cord shroud 3 can be formed by stitching a ribbon along the cord shroud 3 only at definite distances.
  • the loops are rings of metal or fabric or similar suitable material (such as plastic materials) that are attached to the cord shroud 3, e.g. being singularly stitched onto the cord shroud.
  • the panel of window covering material 1 is also provided with a number of loops 5 that are inline with each other and parallel to an edge of the panel of window covering material 1.
  • the loops 5 may be made of fabric or similar suitable material and are attached to the panel of window covering material 1, e.g. being stitched on the panel, or attached adhesively, by means of a tape, or the like.
  • the coupling of the cord shroud 3 with the panel of window covering material 1 is accomplished by clips 6, which may be double-clips.
  • One clip 6 is attached to a loop 4 on the cord shroud 3 as well as in a loop 5 on the panel of window covering material.
  • the distance d between two loops 5 on the panel of window covering material should be short enough for a child's head not to fit through the loop created by the cord section between two clips.
  • Figures 2 and 3 show in a very schematic manner the window covering of Fig. 1 during a lifting process.
  • the lifting is accomplished by pulling the cord 2.
  • the cord shroud 3 contracts, wherein the contraction is enabled by the accordion structure of the cord shroud 3. Due to the coupling between the cord shroud 3 and the panel of window covering material 1, a contraction of the cord shroud 3 leads to a lifting of the panel of window covering material 1.
