BUILDING PANEL WITH A MECHANICAL LOCKING SYSTEM

摘要

A set of essentially identical panels (1, 1′), such as building panels, provided with a mechanical locking system including a displaceable tongue (30), which is arranged in a displacement groove at a first edge of a first panel (1). A second panel is provided with a tongue groove at a second edge. The displaceable tongue is configured to cooperate with the tongue groove (20) for locking together the first and the second edge. The displaceable tongue has a spring constant that varies along the length of the tongue.

1. A set of essentially identical panels is provided with a mechanical locking system comprising a displaceable tongue, which displaceable tongue is arranged in a displacement groove at a first edge of a first of the identical panels, the displaceable tongue is configured to cooperate with a first tongue groove at a second edge of an adjacent second of the identical panels, for locking of the first and the second edges in a vertical direction,
wherein the displaceable tongue is of a longitudinal shape and resilient, a spring constant of the displaceable tongue varies in the longitudinal direction of the displaceable tongue, and a middle section in the longitudinal direction of the displaceable tongue has a higher spring constant than a first edge section of the displaceable tongue.
