From the surface then the cord or rod-like element is visible, In the locked state, the cord or rod-like element is particularly dimensioned so that it completely fills the width of the gap, Advantageously, the cord or rod-like element is slightly wider.

  • the cord or rod-like element can be subsequently pressed or inserted from the surface into the gap or the recess. However, it may also already be connected to a panel, in particular if the cord or rod-like element consists of a compressible material.

Only a larger width of the gap compared to the width of the cord or rod-like element or the diameter should be avoided, otherwise an undesirable gap remains on the surface and the cord or rod-like element dissolves too easily dissolves when this from the Surface has been inserted ago.
  • An interference fit of the cord or rod-like element in the gap is to be preferred, since then the gap-free state is ensured and the cord or rod-like element is held.

  • the cord or rod-like element advantageously comprises a thread which can not be stretched practically, the thread is then always wrapped by a compressible material. This ensures that the cord-like or rod-like element consisting of a compressible material is not disadvantageously stretched by pressing it into a gap or into a recess. If the cord or rod-like element initially stretched, it will contract again when laid. In this case, undesirable areas would occur at the recesses or gaps that are not filled with a cord-like or rod-like element.

Moving further may be particularly undesirable if a small protrusion is present, for example due to a door frame, in a space to which a panel should possibly be closely adjacent.
  • the cord or bar-like element may have a substantially rectangular or square diameter in order to effect a surface finish on the surface.
  • a cord or rod-like element according to the invention has the desired elasticity or flexibility, if the width or the diameter can be reduced by compression. Solid metal or wood is not compressible.
