Definitions

  • the present invention relates to a folding blind according to the preamble of claim 1.
  • Folding blinds are also known as folding shutters.
  • the slatted curtain of such folding roller shutters is guided over deflecting drums mounted on the winding shaft and then folded into a zigzag package.
  • These folding roller shutters have the disadvantage that they can no longer be operated even with little contamination or icing or with little deformation of a slat.
  • Another disadvantage is their comparatively complex construction.
  • 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 curtain Due to the arrangement of the stub axles on the bottom and every second slat from there upwards, the curtain is forcibly folded.
  • the preferred embodiment according to claim 2 has the advantage that all parts are provided by the customer except for the slat curtain can be installed because the installation of the slatted curtain in the guides is only 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, hinged slats 3. Of these slats 3, the bottom is laterally supported with stub axles 4 '(Fig. 2) in the guide slots of the guides 1 and vertically displaceable. Next (counted from the lowest slat), every second slat 3 is provided with side stub axles 4, the stub axles 4 'of the lowest slat 3 being preferably 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 one on the elevator Drums 7 windable elevator belts 8 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 lamella to be pivoted approximately 360 ° around the lamella connected to it, whereby a zigzag folding of a plurality of lamellae 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 panning the lamellae 3 can be favored in that the stub axles 4, 4 'are arranged offset from the longitudinal axis leading through the center of gravity.
  • the two stub axles 4 '(Fig. 7 - 9) of the lowest slat 3 are each pivotally mounted in a bearing body 12 (Fig. 4 - 7) and provided with a locking lug 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 slats 3 When lowering the slat curtain, the slats 3 swivel into their vertical position one after the other, as shown in FIG. 2 in the order of FIGS. 2d to 2a.
  • the lowermost lamella 3 assumes a horizontal position almost to the lowest, in which the locking lug 13 bears against the stop surface 18.
  • the locking lug 13 slides upwards along the wedge flank 20 of the locking spring 17 and presses it elastically outward until it jumps into the locking groove 19 and the locking spring 17 relaxes.
  • the lowest slat is 3 in their vertical position releasably fixed and prevents swiveling movements due to wind attack.
  • the catch 13 When lifting the slatted curtain, the catch 13 first disengages before the folding process begins in the slatted curtain.
  • the bearing body 12 has a vertical passage 21 through which the elevator belt 8 is guided.
  • the lower end of which is firmly connected to a weight 22, which comes into contact with the bearing body 12 when the lamella curtain is pulled up and takes it with it.
  • 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 will increase the weight of the lowest slat greatly enlarged and the slatted curtain reliably stretched 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 slat and is provided with longitudinal guides 25 onto which the lowermost slat 3 with its flanges can be pushed in a form-fitting manner.
  • the bottom stub pair 4 ' is not directly attached to the end of the lamella 3 itself, but rather is inserted into a bore 26 in which it is held non-positively, the bore 26 being located laterally to that longitudinal axis of the load rail 24 is offset, which goes through their focus.
