Embodiment Construction

[0041] For ease of understanding, several locking systems are schematically shown in the drawings. It should be emphasized that improved or different functions can be obtained with combinations of the embodiments.

[0042] All embodiments can be used alone or in combination. Angles, dimensions, rounded portions, spaces between surfaces etc. are merely exemplary and can be adjusted within the basic principles of the invention.

[0043] Figure 2a-2eA first preferred embodiment of the short side locking system is shown, provided with a flexible displaceable tongue 30 inserted in a horizontally extending displacement groove 40 in the edge of the first panel 1 . The displaceable tongue 30 has a pulling extension 31 comprising a tongue pulling surface 32 and a tongue locking surface 33 . The second adjacent panel 1' The pulling surfaces 22, 32 cooperate and pull the displaceable tongue 30 into the tongue groove 20 during the vertical movement. The pulling extension 31 com...

Abstract

The invention relates to a floor panel provided on a short side with a vertical locking system comprising a displaceable tongue which moves in one direction into a tongue groove during the vertical movement of the two panels .

Description

technical field [0001] The present invention relates generally to the field of mechanical locking systems for floor panels and building panels and production methods for inserting tongues into grooves. Background technique [0002] Fields of application of the invention [0003] Embodiments of the present invention are particularly suitable for use with floating floors consisting of floor panels mechanically engaged by means of a locking system integral thereto (i.e. factory installed) made of solid wood or Composed of one or more upper layers of solid wood veneer, decorative laminate, powder-based surface or decorative plastic material, an intermediate core of wood fiber-based material or plastic material, and a lower balancing layer, preferably on the rear side of the core . Floor panels with a surface layer of cork, linoleum, rubber or a soft wear-resistant layer such as needle felt glued to a board, floor panels with a printed and preferably also painted surface and ...
