  • the disadvantage here is the need to insert this spring 34 after inserting the housing 11 through the corresponding opening in the sheet 26 from the rear, and the scratch crack that occurs when inserted by the tooth on the spring 34 is in some circumstances disturbing because it causes rust could lead. It is also not certain whether the shaking movements of the overall arrangement not work out the spring 34 again in the seat shown and then release the closure at some point.

In contrast, the angle at the spring shoulder 70 is 180 °.
  • Fig. 4 a sectional view along arrows IV-IV of Fig. 1, also shows that the material thickness of the spring 46 is substantially the same over its entire width, as well as over its longitudinal extent. Nevertheless, there is an increasing spring force compared to bending towards the end of the spring, due to the increasingly pointed V-shape, that is to say the decrease in the angle ⁇ .

Further in the direction of the flange 30, the spring then increasingly projects with its free end edge, so that she finally lies with her tip 174 behind the sheet of the door leaf 26.

  • a plate spring 55 which is shown in a top view in FIG. 52 and in a side view in FIG. 53, and between the inside housing support surface 55 (see FIG. 38) and a corresponding contact edge 57 of the closing core 59 (see FIG. 44) and causes a defined friction, which is desired here.
  • an O-ring seal 61 can also be seen, for which a corresponding annular space is provided by the closing core 59, see reference number 63.
  • the fastening of the disk 49 on the housing 611 can be carried out with the aid of the tongue 18 held by the screw bolt 22 if the additional axial load resulting therefrom, which is transmitted from the spring 634 to the disk 49 and from there to the tongue 18, from where this axial load via the screw bolt 22, screwed into the threaded bore 65 of the closing core 59, then ultimately transmitted via the surface 57 and the plate spring 55 to the contact surface 15 of the housing base, ie leading to an additional load-related friction, does not interfere.
  • the disk 49 are attached to the housing 611 in some other way, for example by gluing the projections 47 in the recesses 45.
  • the closure can then be dismantled by loosening the bolt 22, for example for the purpose of replacing the locking core with another, without the parts 49, 634 and 611 also falling apart.
  • edge 686 of the spring 634 holds the housing 611 on the door leaf 26. If the spring is to have a paint-scraping effect again, this could be done, for example, by applying a toothing 67 to the bending edge 660, scraping off the paint and oxide residues, in particular on the breakthrough edge or reveal, and exposing a bare metal surface in the entire area of this opening and this also gives the metallic end face 686 the possibility of an earth contact, as can also be seen in FIG. 54.
  • Another advantage of the embodiment with a two-part housing, the two parts not being permanently connected, is that an assembly can still be carried out with a loose fastening screw 22, and only then is the screw tightened, as a result of which an even more precise fixation in the opening would be conceivable.
  • All of the described embodiments have the advantage that an inexpensive plastic housing without thread can be used.
  • the removal of the thread has the favorable effect that no so-called die injection tool is necessary, i. that is, the tool costs for the manufacture of the plastic housing are simpler and therefore cheaper.
  • the disk-shaped end piece 49 has to be made of metal, which causes low costs.
  • the locking core and the other moving parts of a closure are anyway to be made from founders of mechanical strength made of metal, so that in this way the cheap ground connection path described above results.
  • the advantage of the clip fastening by means of the fastening spring described here has the advantage that no "freedom from keys" is necessary on the back of the door leaf 26 in order to put on a fastening nut or also to push on a fastening spring according to FIG. 9.
  • Another advantage is the security against theft, since it is difficult to remove the lock used with the clip fastening. As already mentioned, a special tool is required for this, which an unauthorized person will usually not have at hand.
  • a stop which is realized in the construction according to FIG. 36 by the stops 20 in the disk 49, is not required, or this stop is placed inside the closure, for example in that a projection and a corresponding projection in it Movement-limiting path formed by the closing core or the inner surface of the housing, the disc 49 can also omitted and the spring 634 are held directly by the sash tongue 18.
  • the disadvantage cannot be denied that the sash tongue and screw must also absorb the fastening forces of the fastening spring 634. If you want to avoid this again, the sash housing could be provided with protruding slugs, as was described in the embodiment of FIGS. 12 to 18.
  • the pressure effect of the fastening spring 634 may also be desirable, for example if the plate spring 55 is to be omitted. Then the fastening spring 634 takes over the friction pressure generation.
  • the bends 90 of the fastening spring are each made through 90 °. Instead of a 90 ° position, a smaller turn can also be made, which would enable greater tolerance compensation.
  • closures shown in FIG. 12 with cylinder lock are particularly well suited as mailbox closures, since these cannot be dismantled without authorization and then stolen for your own purposes, because they can only be dismantled using special pliers.
