Definitions

  • the present invention relates to a pleated blind according to the preamble of claim 1.
  • a folding blind of the type mentioned is known from FR-PS 1 358 330.
  • this folding blind only the lowest slat is guided in the side guides by means of axle journals. Elevator belts engage these journals to raise or lower the blinds.
  • the remaining slats are provided with articulated brackets at the ends of their longitudinal edges and thus encompass the side guides. This design causes malfunctions both when lowering and when lifting the slat blind.
  • the present invention has for its object to provide a folding blind which is simple in construction and reliable in operation and does not have the disadvantages mentioned above.
  • the preferred embodiment according to claim 2 has the advantage that all parts can be assembled on site except for the slat curtain, because the installation of the slat curtain in the guides is possible later.
  • a vertically aligned slat stack is created without additional aids when the slat blind is gathered.
  • the basic structure of the folding blind is described with reference to FIGS. 1 to 3. It has two lateral guides 1 which are attached to the reveal 2 of the window opening.
  • the guides 1 essentially have a U-shaped cross-sectional profile, the leg ends being angled toward one another and forming a vertical guide slot.
  • the slat curtain consists of horizontal slats 3 which are connected to one another in an articulated manner. Of these slats 3, the lowest is laterally pivotably and vertically displaceably supported by stub axles 4 '(FIG. 2) in the guide slots of the guides 1. Furthermore (counting from the lowest lamella), every second lamella 3 is provided with side axle stubs 4, the axle stub 4 'of the lowest lamella 3 preferably being provided with additional functional elements which will be explained later.
  • the elevator shaft 6 with the two elevator drums 7 is rotatably mounted in a recess 5 above the window opening in the masonry. It can be driven by conventional drive means, not shown.
  • the elevator belts 8 that can be wound on the elevator drums 7 are guided in the lateral guides 1 to the lowest slat, which is suspended thereon by means of a bearing body 12.
  • the articulated connection of the individual lamellae 3 serves as rubber-elastic connecting links 9 (FIGS. 2 and 3).
  • a connecting member 9 has a Z-shaped cross section with a flexible web 10, which merges into two legs each provided with an edge bead 11, which edge beads 11 are held in a form-fitting manner in the associated flange of the adjacent lamellae 3.
  • This connecting member 9 allows a slat to be pivoted by approximately 360 ° around the slat connected to it, whereby a zigzag folding of a plurality of slats 3 connected to one another is easily possible.
  • the connecting links 9 can extend continuously over the entire lamella length and, if desired, can be provided with openings. However, there is also the possibility of arranging a plurality of such connecting links, the length of which is only a fraction of the lamella length, in parallel and spaced apart over the lamella length.
  • the window opening is closed by the folding blind.
  • the lowest slat is raised first, which pivots in the side guides 1 due to the resistance generated by the slats above it, with which the entire slat 3 located above it (which is not guided in the side guides 1 by means of stub axles) to the outside is pivoted (Fig. 2b).
  • the pivoting of the slats 3 can be favored in that the stub axles 4, 4 'are offset from the longitudinal axis leading through the center of gravity.
  • the slats 3 are gathered in a horizontal position to form a slat packet and sunk in the recess 5.
  • the slat armor is lowered, the slats (starting with the top slat) are swiveled into the vertical position one after the other.
  • the two stub axles 4 '(FIGS. 7-9) of the lowermost lamella 3 are each pivotably mounted in a bearing body 12 (FIGS. 4-7) and provided with a detent 13.
  • the bearing body 12 has a round support 15 which is bounded at the top by an elastically resilient tab 16 directed against it.
  • the locking groove 19 is arranged in a locking spring 17 which is made in one piece with the bearing body 12 and which tapers in a wedge shape towards its free end.
  • the bearing body 12 has a vertical passage 21 through which the elevator belt 8 is guided. Its lower end is firmly connected to a weight 22, which comes into contact with the bearing body 12 from below when the lamella curtain is pulled up and takes it along.
  • the elevator belt 8 is preferably a steel belt.
  • the weight 22 proves to be particularly advantageous when a steel belt is used as the elevator belt 8. If the lamella curtain encounters an obstacle when lowering, the tightening of the elevator belt on the elevator drum prevents a watch spring-like relaxation and jumping out of individual belt windings.
  • this is preferably provided with a loading rail 24.
  • This greatly increases the weight of the lowest slat and reliably extends the slatted curtain when lowered. This further promotes the pivoting of the lowest slat and thus the pivoting of the locking lug 13 into the locking groove 19.
  • the loading rail 24 is a hollow profile which extends over the entire length of the lowermost lamella and is provided with longitudinal guides 25, onto which the lowermost lamella 3 can be pushed in a form-fitting manner with ibren flanges.
  • the bottom stub pair 4 is not directly attached to the end of the slat 3 itself, but instead is inserted into a bore 26 in which it is held in a force-fitting manner, the bore 26 being located laterally to that longitudinal axis of the loading rail 24 is offset, which goes through their focus.
