Definitions

  • the invention relates to a pleated blind, the curtain of which is connected to at least one movable profile strip, the profile body of which is closed off from the curtain by a device for fastening the curtain and carries at least one end an end cap which deflects one from inside the profile strip emerging cord forms, which is then guided under tension on the side edge of the shading surface.
  • the curtain of a pleated blind is hung on an upper ledge, which is to be fixed to the window reveal, and closed off by the movable ledge below.
  • the movable bar is guided by the cords parallel to itself in the plane defined by the attachment of the cords (shading area). Thanks to the friction of the cords against the bar, it can be stopped at any height.
  • four cords are provided, which are guided from the fixed upper bar at various points through the pleated curtain to the movable bar, deflected there and out of the end cap, where they are down are deflected and anchored at the bottom of the window.
  • the fold curtain is closed at both its upper and at its lower end by a movable bar and stretched between two fixed bars arranged at the top and bottom of the window.
  • a pair of cords leads on both sides of the shading area from the upper fixed bar to the upper movable bar and is inserted through their end caps into a central area in which they are led through the pleated blind to corresponding points on the lower movable bar in order to there again to be led outwards to the end caps of this lower movable bar, where they are deflected downwards to an anchoring point on the lower fixed bar.
  • the cord or cords which emerge from a bore in the end cap are only deflected to one side, there are also embodiments (WO 93/18270) in which two cords emerging from the end cap bore to both sides be redirected.
  • the known folding blinds have the disadvantage that the movable bar can tilt about its longitudinal axis, which is technically and aesthetically satisfactory. In part, such a tilting is even promoted by the design of the end cap, as is the case, for example, in the known case in which the opening of the end cap is designed as an elongated hole with a longer axis which is transverse to the shading area. Then the exiting cords adjust themselves off-center and exert a tilting effect on the bar. Also known is an embodiment (prior public use), in which the end face of the end cap is provided with a circumferential, raised edge which contains cutouts above and below a centrally arranged opening designed as a cord deflection for receiving the deflected cord sections. Since the distance between the deflection and the cutout is only two or three millimeters, the tilting effect cannot be significantly reduced.
  • the invention is therefore based on the object to provide a shading device of the type mentioned in the preamble of claim 1 which significantly limits or eliminates the possibility of tilting the movable bar.
  • the solution according to the invention consists in that the end cap is extended beyond the profile body of the profile strip in the line direction by an extension piece, on which a device for aligning the cross-section of the strip with the line direction is arranged.
  • a device for aligning the cross-section of the strip with the line direction is arranged.
  • the end cap expediently consists of a smooth and wear-resistant plastic material.
  • the end cap is a component that is placed on the end of the movable bar or inserted therein, on the one hand to form a visually satisfactory conclusion and on the other hand to take over the technical functions associated with the deflection and guidance of the cords are. It goes without saying that, in the case of symmetrical arrangements, both ends of the movable bar are expediently designed in accordance with the invention.
  • the extension piece is advantageously only provided on the curtain side. This applies in particular if at least one profile diaphragm is arranged on the profile body of the movable bar and extends beyond the device for fastening the curtain on the curtain side of the bar approximately parallel to the curtain plane.
  • the extension piece of the end cap and the profile panel should be approximately flush with each other.
  • the device for aligning the cross-section of the strip to the line direction is expediently formed by a groove which starts at the front side of the strip or the end cap from the opening forming the deflection from which the line exits.
  • the groove expediently extends over the entire distance from the opening to the end of the Extension piece. If it is a design that is only intended for deflection in one direction, it is sufficient to provide the groove only on one side of the outlet opening; However, it is more convenient to arrange them on both sides, so that there is freedom for different line guides.
  • the groove is normally open, the cord being held in the groove due to its inherent tension. However, the invention does not want to exclude the possibility that the groove is completely or partially covered for optical reasons or to hold the cord in it.
  • the cover can be removable to facilitate assembly.
  • the groove can also be made permanent and possibly in one piece with the remaining part of the end cap. This then results in a guide channel for the cord or cords, which should be encompassed by the term groove, as used in the present context.
  • Another conceivable modification of the groove is that the groove flanks are shortened to a short section, so that in extreme cases the walls forming the groove flanks become two projections arranged on both sides of the cord. So that these have the desired alignment effect, they should be arranged at a distance from the outlet opening. If the two projections are connected to one another on the open side, there is an eyelet which can also be considered as an alignment device in the sense of the invention.
  • the surfaces deflecting them are at a distance from one another in the shading plane which is greater than the freedom of movement of the cords or Cord sections across.
  • the outlet opening is expediently designed as an elongated hole, the longitudinal axis of which extends in the shading plane and the ends of which form the deflection surface for the two cords.
  • the movable lower rail 1 of the fold blind 2 indicated by dash-dotted lines has a profile body which is shown as an upwardly open U-profile, as is known for such purposes. It is formed by the two profile legs 3, the web 4 connecting them and the mutually facing flanges 5 serving to fasten the curtain 2 at the ends of the profile legs 3.
  • the profile legs 3 can comprise profile projections 18 beyond the web 4, which can be used, for example, to attach a handle to the bar 1.
  • the end cap 7 made of smooth and wear-resistant plastic such as polyamide forms a substantially flat disc 8, the outline of which is approximately the same as the front outline of the profile body 3, 4, 5, so that its side surface 9 adjoins flush with the side surfaces of the profile body in the assembled state.
  • the part of the plate 8, the extent of which corresponds to the cross-sectional shape of the profile body 3, 4, 5, ends at the flanges 5 or at the grooves 10 provided in the side surfaces 9 of the end cap, which adjoin grooves 11 which are not of interest here Reasons are provided on the bar 1.
  • the plate 8 is continued by an extension piece 12, the height of which is the same as that of the panel 6 and is flush with the top.
  • bar 1 is the end cap symmetrical. Their top and bottom sides are designed as rectilinear connecting surfaces that connect to the highest and lowest points of the strip 1.
  • the disc 8 has on its side facing the bar 1 plug-in lugs 13 which can be snugly inserted into the cavity of the profile body of the bar 1 in order to hold the end cap on the bar in the intended position.
  • an outlet opening 14 for cords 15 and 16 is provided in the disc 8, which run on the one hand in the cavity of the profile body and on the other hand from the rounded outer edges of the outlet opening 14 to the section can be redirected up or down.
  • the two cords shown only one cord could be provided or two cords which are deflected in one and the same direction.
  • the outer edge of the outlet opening 14 is smooth and rounded, so that it does not act on the cords 15, 16 in a wearing manner or become significantly worn itself when the strip 1 is raised and lowered and the cords slide over the deflection surfaces.
  • the outlet opening 14 is designed at least on its outlet side as an elongated hole with the longer axis in the direction of the cord sections running outside. Their width is so small that the cords have little or no latitude transversely to the curtain level and are therefore centered in the elongated hole ends. The width of the opening is of course made so large that it can accommodate the largest number of cords occurring side by side.
  • the spaced arrangement of the deflection surface assigned to each cord results in a slight lateral mobility of the cords and an uprighting torque and thus the bar 1, if a tilting should have taken place about the longitudinal axis of the bar.
  • the groove is therefore aligned with this plane, as a result of which the strip 1 is also held in the intended position.
  • this also applies to the cord 16 which is still running at the bottom, since the groove distance assigned to it is greater than in the case of an opening which is centered on the extensionless part of the disk 8.
  • the cross-sectional shape of the strip 1 is aligned with the curtain level in such a way that its side surface facing the room runs parallel to it.
