Definitions

  • the invention relates to a push-button connection of the type mentioned in the preamble of claim 1.
  • a metallic push-button part is flanged with its flange around a ring which has bendable tines on its inner edge and thereby a prefabricated one Forms unit that is ready to be attached via its tines to a carrier web by the prongs piercing the carrier web in a plate-shaped retaining element on the opposite side of the carrier web in an annular channel and bent there at their ends.
  • This push-button part consists of a conical, rigid funnel, from which cylindrical walls extend and have lips that act as matrix-shaped dome surfaces at their ends.
  • the cylindrical walls bend at their attachment point, while the conical funnel remains rigid. Therefore, essentially the same forces are required for coupling and uncoupling, which is undesirable for some applications.
  • the push button part is disruptive and affects the good appearance of the push button connection.
  • the invention has for its object to develop an inexpensive push-button connection with a dome-shaped push-button part according to the preamble of claim 1, which is easy to manufacture on the one hand, adapts well to the carrier web and on the other hand with ideal closing properties when coupling and uncoupling the associated complementary push-button part has patriform domed surfaces.
  • This is achieved according to the invention by the measures specified in the characterizing part of claim 1, which have the following meaning:
  • the matrix-shaped dome surfaces are created simply through the central hole and the slots in the cup bottom, without the need for complex deformations.
  • the cup side wall on the other hand, creates the assembly with a fastening part by flanging the flange around the flat ring.
  • the assembly according to the invention is thus simple and inexpensive to manufacture. Nevertheless, there is an interaction between the special fastening in this assembly on the one hand and the matrix-shaped dome surfaces on the other.
  • the cup base If a push button with male-shaped dome surfaces is engaged, the cup base is supported on the inner edge of the flat ring by the fastening part, which is why there are only relatively short radii between the inner ring edge and the opening of the female dome surfaces for the deformation of the base area. A comparatively high force must therefore be applied for the deformation work. Conversely, when uncoupling, the cup base can yield up to the outer edge of the flat ring, which is why much larger radial lengths are now available for the deformation. Therefore, only a small force is required to uncouple.
  • the cup shape thus results in different closing forces when coupling and uncoupling the complementary push-button parts, which have male-shaped coupling surfaces, with the structural unit according to the invention.
  • the good appearance of the structural unit according to the invention on the carrier web is promoted in particular if, according to claim 5, transparent plastic is used for the plate forming the cup, because then, after the attachment, the carrier web shines through the material and automatically brings about an optical adaptation .
  • transparent plastic is used for the plate forming the cup, because then, after the attachment, the carrier web shines through the material and automatically brings about an optical adaptation .
  • a dyeable plastic is used for the cap covering the ring body on the viewing side.
  • plastic plate for the cup is obtained by printing on a transparent film. This enables an individual color design, whereby the transparent material of the film also protects the printing inks on the back.
  • the push-button part 11 consists of a plastic plate 46 of predetermined plate thickness 47, which is cut out of a plastic sheet and shaped into a cup 50 with a U-shaped profile in a radial section.
  • matrix-shaped coupling surfaces 15" are formed, which consist of a central breakthrough 16 "and from it cross-shaped radial slot 18" exist. Because of its formation from a web, the plate thickness 47 is essentially the same everywhere, but a profile bend 52 is provided in the area of the coupling surfaces 15 ′′.
  • the plastic plate 46 could be formed from transparent plastic.
  • FIG. 2 which in the present case consists of a metallic toothed ring 12 ", which is constructed from a flat ring 48, on the inner edge of which tines 24" are arranged.
  • the ring 48 has an outer circumference which fits into the opening width 53 of the cup 50 from FIG. This is used to create a structural unit 10 "according to FIG. 3.
  • the push-button connection is installed in such a way that the structural unit 10 "is led through from the front side 33 of the carrier web 32 indicated in FIG. 3.
  • the sharpened tine ends make their way through the carrier web 32 and eject again on the carrier rear side 34
  • a counter-holding member which is designed here as a metallic ring body 35.
  • the ring body 35 has an annular chamber 36 which creates an annular gap 38 on a central inner flange 47.
  • the annular gap 38 has one of the ring arrangements of the tines 24 " of the structural unit 10 ".
  • FIG. 6 shows a counter-holding member 35 'modified in comparison with this, but which also starts from the ring body 35 according to FIG.
  • a plastic cap 44 is placed over the face of the ring body 35, which in turn is produced from the same plastic plate as the cup for the assembly 10 "of FIG. 3. Both plastics have the same color.
  • the face of the counter-member 35 'and the assembly 10 "therefore have an identical appearance. After the connection, the toothed ring 12 "and its prongs 24" are invisible.
  • plastic plate 46 for the push-button part 11 ′′ or the plastic cap 44 from a transparent film web, which consists, for example, of polycarbonate.
  • This transparent film is printed on the back, shaped in a cup or cap shape and cut out.
  • the printing appears on the inner surface 49 indicated in FIGS. 1 and 6. This printing appears on the face side of the object through the film material, thereby shielding the printing from scratches.
