Definitions

  • the invention relates to a Roman blind, the slats of which are held by supporting members which are connected to the flanged edges of the slats by means of metallic connecting members anchored in the latter.
  • the present invention therefore aims to create a slat blind of the type mentioned, the slat / supporting member connection of which does not require any tool-related bending from the end flanges of the end parts of the connecting members, and thus enables a fully automatic production of the connection in a simple manner.
  • the slat blind according to the invention is characterized in that the flat metal pieces forming connecting members have a head and an at least approximately parallel sidewalls in the unassembled state, projecting beyond the flange diameter, and having at least one tip or cutting edge, with the head being a one-piece clamping ring the flaring wall is driven into the flaring cavity and is compressed by hitting the opposite flaring wall by permanent deformation under convex curvature of the side walls and is thereby clamped between the two flaring walls.
  • the clamping ring is expediently closed on all sides and has suitable cross-sectional weakenings on the ring parts running between the cutting edge or tip and head, in order to ensure the necessary bulging of the ring parts originally having outside sides when the cutting edge or tip hits the opposite flanging wall; when the clamping ring is driven into the first flanging wall, it tears out narrow flanging wall strips from the latter, which abut the curvature of the ring parts against the latter and thus additionally to jamming the compressed clamping ring transversely between Clamp the clamping ring in the longitudinal direction of the flange on the two flange walls.
  • the connecting member thus sits absolutely firmly in or on the flanged edge and cannot be relaxed in its seat by the loads and vibrations acting on the head of the connecting members when the store is actuated via the loops.
  • a conventional slat 1 of a Roman blind is provided, for example, with flanged edges la bent in the same direction (only one drawn).
  • Metallic connecting members 2 are fixed to these flanged edges, for example Attack textile loops on a carrier tape (not shown). 2 shows, these connecting links 2 are relatively thin, flat elements which are expediently produced by stamping. They have a head 3 which has a recess 3b which can be closed by means of a flexible hook 3a for receiving the textile loop (not shown) fixed to the carrying band. On the head side facing away from the end face of the head 3, two shoulders 3 c are formed, between which a clamping ring 4 protrudes from the head 3.
  • This clamping ring 4 has, in the unmounted state, as shown in FIG. 1 with dashed lines at 4 1 , parallel to one another and at right angles from the shoulders 3c projecting outer sides, which end via a first convex and then concave curved front part in a centrally arranged cutting edge 5.
  • the sealing ring recess 6 1 of the unmounted ring has an approximately rounded triangular shape, such that both on both sides of the cutting edge 5 and in the vicinity of the head the clamping ring has reduced cross sections forming weak points 7a, 7b.
  • the axial length of the unmounted clamping ring 4 1 measured from the shoulders 3c to the cutting edge 5 is considerably longer (in practice about twice as long) than the flange diameter at the point of use of the clamping ring.
  • the cutting edge 5 of the clamp rings 4 meets the inner flanged wall during the driving-in process, this cutting edge will penetrate more or less into this flanged wall and possibly also cut or cut through it; the sheet metal strip 1b, which acts as a brake in addition to this wall, brakes the impact effect in such a way that the clamping ring, which is permanently deformable thanks to the weak points 7a, 7b, is first slightly and then increasingly compressed; the ring portions adjacent to the cutting edge 5 lie against the inner flanged wall since the lateral ring portions bulge outwards. This also results in a corresponding arching of the inwardly curved wall strips 1b.
  • the driving-in and thus the upsetting process are ended as soon as the shoulders 3c of the head 2 serving as a stop abut the outer wall of the flange la.
  • the shape of the clamping ring 4 with the flattened ring opening 6 achieved by permanent deformation of the clamping ring material inevitably leads to three-dimensional clamping of the connecting member in or on the flange 1a.
  • the dimensions of the connecting member produced, for example, from annealed, stainless steel by stamping are matched with regard to the original length of the clamping ring, the shape and size of the different ring cross sections and the cutting edge, the shape, size and wall thickness of the flange. It is essential that the clamping ring has sufficient compression length and that the original ring opening together with the weak points guarantees that the ring halves are bent outwards.
  • the holding loops of the carrying tapes can be hooked into the recess 3b both before and after the connecting member has been driven in.
  • the cutting edge 5 could also be chamfered laterally to a point. To be It is also important to ensure that the described anchoring of the connecting link in the flange is in no way hindered by a noise-damping and sealing strip made of plastic or rubber inserted in the flange.
  • the clamping ring of the connecting member 2 is and remains closed.
  • this clamping ring 4 1 or 4 is cut open in the region of the cutting edge 5, as shown at 4 a.
  • This has the consequence that the front part of the clamping ring forming the cutting edge bends slightly more inwards when it hits the inner wall of the flange la; the cutting edge itself remains intact.
  • the ring opening 6 is separated from the suspension opening 3b in the link head 3 for the holding loop, the two openings 6, 3b form a unit in the embodiment according to FIG. 3.
  • the slit of the clamping ring 4 1 allows the holding loop to be inserted by temporarily spreading the clamping ring before the connecting member 2 is fitted.
  • a separate opening 3b for the holding loop analogous to FIG be.
  • FIG. 4 shows a connecting member 2, the permanently deformable clamping ring 14 1 of which is provided on its front part with two cutting edges 15.
  • this connecting member 2 is driven into the flange 1a, a wall strip corresponding to the edge spacing is completely cut out of the flange wall, so that the tape strips 1b to be bent open become somewhat shorter in this case.
  • Self Ver Of course, in this case the clamping ring opening 16 * in the cutting edge area of the clamping ring must be widened somewhat in order to ensure the perfect arching of the side parts of the clamping ring during the upsetting process.
