Definitions

  • the invention relates to an end piece for guiding the slats of slat blinds in the lateral guide rails according to the preamble of patent claim 1.
  • the end pieces are riveted to the front ends of the slats if they are made of metal, or ultrasonically welded if they are made of plastic.
  • the riveting of the metallic end pieces requires only short manufacturing times, but such end pieces are more expensive than those made of plastic.
  • the ultrasonic welding of the inexpensive plastic end pieces requires a manufacturing time which is several times longer and which is limited by the ultrasonic welding process.
  • the present invention therefore has as its object to provide an end piece which can also be fastened to a lamella in a plastic version as quickly as a metallic end piece to be riveted on.
  • the end piece can be connected to the slats fully automatically using simple devices.
  • the supply of the initially integrally formed connecting part to the assembly machine is easy to accomplish, and the punching in the lamella can be carried out in a punching stroke running parallel to the assembly of the end piece.
  • an end piece for a lamella 3 (shown in dash-dotted lines) is shown with reference number 1 before it is connected to the lamella 3.
  • the end piece 1 consists of an elongated body, one end 5 of which is split by a recess 7 in an underlying support part 9 and an upper locking part 11.
  • the support part 9 is essentially rigidly connected to a bolt 13 which engages in a guide 15 which guides the slats 3 in the vertical direction of displacement.
  • the guide 15 is only shown in a hint, since it is not the subject of this invention and its design can be adapted to the respective needs.
  • the supporting part 9 consists essentially of a supporting surface 17 receiving the lamella 3, on which a cam 19 centering the lamella 3 is attached.
  • the cam 19 is penetrated by an opening 21, the cross section of which undergoes an abrupt widening in the lower region, forming a shoulder 23.
  • the cam 19 may have a round, elongated (as shown) or any other cross section.
  • the latching part 11 has a pressing surface 25 which is parallel to the supporting surface 17 and on which a preferably mushroom-shaped projection 27 is attached.
  • the projection 27 and the opening in the cam 19 have, as is known in the case of snap-in connections, complementary shapes, the distance between the surfaces 17 and 25 corresponding to the thickness of a lamella 3 in the engaged state.
  • the latching part 11 is connected to the supporting part 9 via a predetermined breaking area 29.
  • the predetermined breaking area 29 is circular and connects a peg-like extension 31 on the latching part 11 to the upper edge of a bore 33 in the supporting part 9 that is congruent with the extension 31.
  • the locking part 11 and the support part 9 preferably have the same outer shape.
  • the end pieces 1 are pushed axially onto the lamellae 3 by hand or by machine to an assembly machine (not shown) and centered with their punched-out recess on the cam 19. Now the mutual position of the lamella 3 and the end piece 1 is clearly defined. With a force F acting vertically from above on the locking part 11, the locking part 11 is pressed down. The connection breaks in the predetermined breaking area 29, and the extension 31 slides into the bore 33. In parallel, the projection 27 penetrates the recess in the lamella 3 and the opening 21 in the support part 9. The mushroom-like, enlarged edge of the projection 27 becomes during the passage pressed through the opening 21 and then engages on the shoulder 23.
  • the geometric dimensions of the projection 27 and the opening 21 are dimensioned such that, after the two parts have engaged, the lamella 3 is immovably clamped between the supporting part 9 and the latching part 7.
  • the tolerances on the fastening device and the material used can be selected such that the detent part 11 can only be separated from the supporting part 9 by force and the parts are destroyed.
