  • the resilient deformation of the contour of the locking pin is enforced by geometric relationships of the groove and the spring, in that the clear width of the groove is smaller than the maximum thickness of the spring.
  • the clear width of the groove increases. After snapping it takes her original measure again. Therefore, the known floor panel pays to the well-known group of tongue and groove impact profiles.
  • the disadvantage is that the locking pin can be broken if an excessive or incorrect impact is exercised. Also, the shock requires a metered force that can be easily exceeded and leads to excessive elongation and also to a strong noise.
