background of the present invention

Laminate flooring generally includes thick upper decoration laminating surface layer and the thick bottom balance layer consisting of laminate, plastics, paper or similar material of 0.1-0.6mm of fiberboard core, 0.2-0.8mm that 6-12mm is thick.Laminating surface can comprise melamine impregnated paper.The most frequently used core material is the fiberboard with high density and good stability, and it is commonly referred to HDF---high density fiberboard.Sometimes also by MDF,---medium density fibreboard---is used as core.

Traditional laminate floor panels of the type is to engage by gluing joint tongue-trough connection.

Except this traditional floor, floor panel has developed into without using glue, but carries out mechanical engagement by so-called mechanical locking system.These systems comprise the locking device of horizontal and vertical locking panelling.Mechanical locking system forms by the core of machine panelling conventionally.

Alternatively, the each several part of locking system can for example, be made by independent material (aluminium or HDF), and material and floor panel that this is independent are integrated, that is, in the manufacturing process of floor panel, engage with floor panel.

The major advantage with the floating floor of mechanical locking system is, they are easily installed.They can also easily be taken again, and reuse in different places.

the definition of some terms

Hereinafter, the visible surface of mounted floor panel is called " front side ", and the opposite side towards subfloor of floor panel is called " rear side ".Edge between front side and rear side is called " trip edge "." horizontal plane " refers to the plane of the exterior section extension that is parallel to surface course.The next-door neighbour's at two adjacent bond edges of two floor panels that are bonded together juxtaposition top defines " vertical plane " perpendicular to this horizontal plane." vertically " refers to that along D1 direction, being parallel to this vertical plane locks." horizontal lock " refers to that along D2 direction, being parallel to this horizontal plane locks.

" on " refer to towards front side, D score refers to towards rear side, " inwardly " mainly refers to flatly inside and the central part towards panelling, and " outwards " mainly refers to flatly the central part away from panelling.

" locking system " refers to coefficient Connection Element, their vertical and/or level connection joint floor panels.

correlation technique and problem thereof

In order vertically and perpendicular to the first horizontal direction mechanical engagement at edge to grow limit and minor face, can use some methods.Wherein a kind of the most frequently used method is angle engaging (angle-snap) method.By drift angle tilt (angling) long limit is installed.Then along long side, panelling is displaced to latched position.By horizontal snap lock minor face.Vertical bindiny mechanism is joint tongue and groove normally.During horizontal shift, with the batten of locking member, be bent, and when EDGE CONTACT, batten rebounds, and locking member enters lock slots horizontal lock panelling.Owing to needing with hammer and knocking piece to overcome friction and the crooked batten between long limit during snap action, therefore this engagement connection is complicated.

Similarly locking system can also be manufactured with rigidity batten, and they are connected with inclination-drift angle, drift angle gradient method in the situation that all drift angle tilting to latched position with long limit at minor face.

Recently introduced very effective locked system, it has the independent flexible or displaceable integrated joint tongue being positioned on minor face, this joint tongue allows only by drift angle tilting action, to install, and this is commonly referred to " vertical folding (vertical folding) ".This system is at WO2006/043893(

innovation AB) in, have illustrated.

As shown in Fig. 1 a-1f, on market, used several pattern.Fig. 1 a, 1b show the flex tongue 30 with the flexible snap-latch piece extending from edge.Fig. 1 c, 1d show the be shifted joint tongue with inner side flexible part, and this inner side flexible part can be in the cross section of joint tongue or along joint horizontal curvature.This system is called vertical snap fit system, and they provide and automatically locked during jackknife action.

This locking system can also utilize thruster action locking, so that when adjacent short side folds into subfloor downwards, the joint tongue 30 that can be shifted is pushed latched position from long side.This thruster action may be difficult to be combined with the inclination of simple drift angle, and for wide panelling, friction may be too strong.

Fig. 1 e shows the downward folding system with flex tongue 30, and this flex tongue 30 is made one with core.Fig. 1 f shows the long limit locking system in downward system, and it tilts to connect by drift angle.

Although these systems are very effective, the space being still improved.Vertical snap fit system is designed to have joint tongue on batten panelling.Reason is, when top edge manufactures (being generally not always the case) while there is no oblique angle, only can on folding panelling, form the slidingsurface of inclination.At production period, be difficult in independent joint tongue 30 insertion grooves 40, this groove 40 is positioned at batten 6 tops that comprise locking member 8.Latching force depends on engaging resistance.When joint tongue is extruded inward and when joint tongue springs in joint tongue groove 40 backward, only has and utilize high engaging resistance could realize high latching force.This has produced the separating force that is tending towards pushing open panelling during folding.If the flexibility of joint tongue and extruding force reduce along with passage of time, this locking may lose intensity.This flexibility is must be quite large and allow flex tongue along both direction about 1-2mm that is shifted.Material for the manufacture of this joint tongue is quite expensive, and, conventionally with glass fiber, strengthen this flex tongue.

If independent joint tongue can be fixed on folding panelling, and if can exempt the engaging in the system automatically locking during folding, this will be very favourable.
