" locking system " refers to coefficient connecting element, they vertical and/or level connection joint floor panels.

Correlation technique and problem thereof

In order to vertically mechanically engage long limit and minor face with the first horizontal direction being perpendicular to edge, it is possible to use If drying method.One of which most common method is that angle engages (angle-snap) method.Tilt (angling) by drift angle to come Long limit is installed.Then along long side, panelling is displaced to latched position.By horizontal snap lock minor face.Vertical bindiny mechanism leads to It is often joint tongue and groove.During horizontal shift, the batten with locking member is bent, and, when EDGE CONTACT, batten bullet Return, and locking member enters lock slots horizontal lock panelling.Owing to needing to use hammer and tap block during snap action Overcoming the friction between long limit and bending batten, the most this being connected together is complicated.

Similar locking system can also manufacture with rigidity batten, and they tilt to lock at minor face and all drift angles, long limit Location connects with inclination-drift angle, drift angle gradient method in the case of putting.

Recently have been introduced into very effective locked system, it have be positioned on minor face individually flexible or Displaceable integrated joint tongue, this joint tongue allows only to be installed by drift angle tilting action, and this is commonly referred to " vertical folding (vertical folding)”.This system WO2006/043893 (Innovation AB) in have described Bright.

As shown in Fig. 1 a-1f, market employs several pattern.Fig. 1 a, 1b show have from edge extension The flex tongue 30 of flexible snap-latch piece.Fig. 1 c, 1d show have inner side flexible part can displaceable tongue, inside this, flexible part can With in the cross section of joint tongue or along joint horizontal curvature.This system is referred to as vertical snap fit system, and they are at jackknife action Period provides locking automatically.

This locking system can also utilize side to promote and lock, in order to be folded downwardly to subfloor at adjacent short side Time, latched position can be pushed from long side by displaceable tongue 30.This side promotes and is likely difficult to and simple drift angle bevelled junction Close, and for wide panelling, friction may be the strongest.

Fig. 1 e shows that have a flex tongue 30 is folded down system, and this flex tongue 30 is formed integrally with core.Figure 1f shows the long limit locking system in downward system, and it tilts to be attached by drift angle.

Although these systems are highly effective, but still there is the space of improvement.Vertical snap fit system is designed to inlay at batten There is on plate joint tongue.Reason is, when top edge is formed without oblique angle (being not always the case under normal circumstances), is only capable of at folding The slidingsurface of inclination is formed on folded panelling.Being difficult in single joint tongue 30 insertion groove 40 at production period, this groove 40 is positioned at Above the batten 6 of locking member 8.Latching force depends on engaging resistance.When joint tongue is extruded inward and works as joint tongue backward When springing in joint tongue groove 40, only utilize height engaging resistance could realize high latching force.This generates and tend to pushing away during folding Open the separating force of panelling.If the flexibility of joint tongue and extruding force elapse over time and reduce, this locking may lose intensity. This flexibility have to be quite big and allow flex tongue to shift about 1-2mm along both direction.For manufacturing the material of this joint tongue Expect fairly expensive, and, generally use glass fibre to strengthen this flex tongue.

If individually joint tongue can be fixed on fold panel, and if able to exempt and carrying out during folding certainly Engaging in the system of dynamic locking, this will be highly advantageous.
