U.S. patent 8,756,899 has been assigned to Välinge Innovation AB protects methods for assembling resilient floorboards provided with a mechanical locking system by using the resiliency of the floorboard, according to the company.
By upwardly bending a first floorboard at its first edge such that the first edge is curved, locking is facilitated and the force required to lock the floorboard with an adjacent floorboard is reduced. Further, by bending the first floorboard at its first edge, positioning of a downwardly protruding locking element is facilitated.
