Definitions

  • the invention relates to a covering of mechanically interconnectable panels.
  • Wall, ceiling and floor coverings such as prefinished parquet, real wood floors or laminate flooring, consist of several rows of predominantly rectangular panels in their configuration.
  • the panels have on a longitudinal side and on a head side continuous grooves and on the respective opposite longitudinal side or head side continuous springs, which are adapted to the grooves form-fitting manner. By connecting tongue and groove the panels are laid, the panels of two adjacent rows are offset from one another.
  • the WO 2011/012104 A2 describes such a system of mechanically interconnectable panels.
  • the mutually complementary sides each have a groove with different lengths of upper and lower groove cheeks.
  • a spring is held in one of the grooves.
  • the protruding from the groove part of the spring is displaced and intended to engage in the corresponding groove of the adjacent panel.
  • the spring has a projection which abuts when joining the longer groove cheek of the other panel.
  • the spring is moved so that it engages in the assembled position in the adjacent groove and locks the two panels together.
  • the free end of the spring is pushed into the adjacent groove.
  • the prior art is also the DE 10 2012 105 793 A1 to call, in which a spring is slidably held with its foot in a holding and is moved as a whole. Due to an obliquely formed locking surface, an upper surface of the groove, which serves as a pressing edge, is lower than the locking edge.
  • the WO 01/98604 A1 discloses a covering of mechanically interconnectable panels, wherein a spring used for locking has a foot held in a receiving groove and a connecting portion adjoining the foot.
  • the connecting portion is configured V-shaped and is intended to catch behind a locking edge of a U-shaped, upwardly open receiving groove of the adjacent panel.
  • One leg of the V-shaped locking element automatically snaps by a spring force behind a locking edge of the adjacent panel.
  • the DE 10 2009 041 297 A1 discloses a covering of mechanically interconnectable panels, in which the locking is effected by a spring element which, when joining adjacent elements on one of Locking edge opposite support surface of the adjacent panel slides, wherein the support surface is inclined to the locking edge facing a laying plane and causes a horizontal displacement of the spring element behind the locking edge.
  • the WO 2013/025164 A1 also discloses a covering of mechanically interconnectable panels, in which the locking takes place via sliding springs.
  • the spring is held with its foot displaceable in the retaining groove and is pivoted as a whole.
  • the prior art includes systems in which not the free end of the spring, but a central region of the spring is displaced into the groove of the adjacent element ( EP 2 037 128 A1 ).
  • the free end of the spring is pushed behind a locking edge, which is located in the same panel in which the spring is also held with her foot.
  • the spring is different than the one in the WO 2011/012104 A2 described principle unfolded, but folded in a manner, the fold, but not the free end of the spring is displaced in the direction of the adjacent panel.
  • the present invention seeks to show a covering of mechanically interconnectable panels, in particular a floor covering, wherein the locking mechanism is improved using separate springs in terms of mountability.
  • the locking mechanism according to the invention is based on the principle that the spring should be stretched.
  • the locking engagement is provided by the free end of the locking body.
  • the spring is at least in three parts, with this structure refers to the functional sections of the spring.
  • the spring is preferably integrally formed of the same material.
  • the foot is used to fix the spring.
  • the connecting portion allows a relative displacement of the locking body in the direction of the adjacent panel. Therefore, the connecting portion is articulated in its two transition areas to the foot and the locking body, but at least elastically deformable to allow a relative displacement of the locking body relative to the foot or the panel that holds the spring.
  • Decisive for the locking is the guided movement of the locking body.
  • the locking groove support surface which is formed on a support projection.
  • This support projection is located on a lower groove flank.
  • This groove flank is longer, in particular by a multiple longer than the upper groove flank of the locking groove.
  • top refers to the visible side of the panel with respect to the panels and the term “bottom” refers to the underside of the panels.
  • the locking groove extends to the end of the support surface on the support projection.
  • a normal vector exiting perpendicularly from the support surface has a vector component facing up and another vector component pointing in the direction of the first panel. The normal vector therefore points in the direction of the locking groove.
  • the support surface is inclined so that the connecting portion of the spring upon contact with the support surface upwards is pressed. With the connecting portion and the locking body is pivoted. By this upward shift of the locking body is simultaneously displaced in the direction of the adjacent panel. Relative to the laying plane, the spring thereby becomes longer and protrudes further from the second panel relative to its starting position. Due to the position and inclination and contour of the particular concave support surface, the deflection of the connecting portion can be adjusted with the adjoining locking body, so that there is the desired movement.
  • the connecting portion in a preferred embodiment obliquely downward toward the bottom of the panels, so that it can be deflected upwards at all, the locking body should point in its initial position obliquely up to the top.
  • the locking body is therefore relatively strongly angled relative to the connecting portion in its initial position.
  • a lateral deflection is already achieved.
  • a further deflection is achieved by the interaction with a pressing edge, which is formed on the second panel, that is, on the panel on which the spring is held.
  • the locking body is not folded and moved in the direction of the foot, but moved with its free end in the direction of the adjacent panel, whereby the free end grasps behind a locking edge of the locking groove. Due to the material tension within the thus stretched spring, the locking body endeavors to slip out of the locking groove. Deep locking grooves could prevent slipping out, but more material would have to be removed from the panel for fabrication, which means increased manufacturing costs and material loss.
  • the pressing edge has a greater distance than the locking edge. The pressure edge is therefore not at the same height of the locking edge or the upper groove flank, but is located in front of the mouth of the locking groove, so to speak, in the mouth region.
  • the position of the pressing edge reliably prevents the free end of the locking body from slipping out of the locking groove.
  • the locking groove can therefore be very short in the region of the upper groove flank. It is sufficient that only one tip of the locking body grasps behind the locking edge in order to securely lock the panels together, since the spring exerts a pressure from below on the upper groove flank of the locking groove. Since the spring is held by the foot on the second panel, an equal force is applied via the foot to the adjacent second panel, so that the adjacent, second panel is pressed down. The panels are thereby pulled or pressed against each other perpendicular to the laying plane.
  • the invention has the advantage that the locking groove can be formed with a very small depth.
  • a less profiled or less deep grooves have the advantage that the material in the front area of the panels is not so much weakened.
  • a small groove depth has manufacturing advantages as well as design advantages.
  • pressure edge is representative of a means for exerting pressure by a protruding area, in particular a corner area. It may therefore also be an area such.
  • a pushing edge in this sense is also a projecting cam or ledge that is oriented to contact the locking body.
  • the retaining groove and also the locking groove are preferably oriented substantially horizontally. This is due to the fact that a locking is to be achieved perpendicular to the laying level.
  • the grooves do not have to run with their respective flanks parallel to the laying plane, but can also be completely or partially unparallel to the laying plane with respect to each individual flank. It is important, however, that the slot mouth of at least the locking groove is open to the side of a panel.
  • the retaining groove for the spring merely has the function of holding the foot and transmitting the force of the spring originating from the locking to the panel. For this purpose, essentially horizontally oriented retaining grooves with open to the side of the panels Nutmündache.
  • the retaining groove is perpendicular to the laying plane and therefore open at the bottom.
  • Intermediate positions between a vertical and horizontally oriented groove are also possible, as long as this manufacturing advantage and structurally meets the requirements to keep the spring safely, to allow sufficient displacement of the locking body and to provide a transfer of the residual stresses of the spring on the respective panel .
  • the foot can also latching projections for anchoring such. B. have a Christmas tree profile.
  • the spring should be held securely in the locking position behind the locking edge, that is, engage in the locking groove. So that there is no displacement of the spring in the locked position, it is provided that the pressing edge in the locked position summarizes in a recess on the upper side of the locking body.
  • the top of the locking body faces the top of the panels. The upper side is, as it were, facing the connecting section. In the unlocked position, the top is closer to the connecting portion. This side of the locking body could therefore also be referred to as the back.
  • the pressing edge In order to achieve a defined locking position of the pressing edge, it should snap into the recess on the top of the locking body. As a result, the locking body neither before nor back.
  • the pressing edge has less in the locked position the task to push the locking body in the direction down, rather than to prevent it from slipping out of the locking groove. Therefore, the depression on the upper side of the locking body has the function, as it were, that when the locking body engages in the locking groove, the pressing edge is relieved against forces acting from below.
  • the depression is instrumental in blocking the locking body against horizontal locking.
  • the relief of the pressure edge by the recess allows the locking body is lifted in the locking position of the lower groove flank of the locking groove and a force towards the top of the first Paneels on the upper groove edge of the locking groove exerts. There may therefore be a gap between the supporting projection and the locking body in the region of the support surface. In the context of the invention, however, it is not excluded that the locking body is clamped between the support surface and the upper groove flank of the locking groove. Advantageously, it rests mainly on the upper groove flank and partly on the pressing edge, wherein the vertical forces are absorbed mainly by the upper groove flank.
  • the free end of the locking body is substantially triangular.
  • an upper edge of the triangular end is in the installed position on the upper groove flank of the locking groove.
  • the base of the free end is part of the locking body.
  • the lower edge of the triangular end of the locking body is at least partially against a groove bottom of the locking groove.
  • the pointed end which is provided in the manufacturing process with a round tip, allows engagement of the locking body in the transition region between the upper, substantially horizontally oriented groove flank of the locking groove and its groove bottom. Since, in the case of locking relative to displacements vertical to the laying plane, the interaction in the area of the upper groove flank is decisive, in order to avoid a height offset of the adjacent panels, the spring can be correspondingly short.
  • the groove bottom in combination with the press edge, has the function of determining the horizontal position of the free, triangular end.
  • the locking body should not be able to be moved deeper into the groove automatically. It therefore abuts the groove bottom.
  • the lower flank of the triangular locking body is substantially parallel to the groove bottom.
  • a groove base which runs perpendicular to the laying plane, instead of a lower flank, one can also speak of a front flank or side flank of the triangular end.
  • the triangular end is in a sense designed as an isosceles triangle. At this triangular end connects to the top of the locking body serving as a detent recess for the pressing edge.
  • Connecting portion of the spring toward the cross section of the locking body is preferably tapered to allow sufficient mobility of the locking body relative to the connecting portion. This transition region between connecting portion and locking body may also be referred to as a hinge portion.
  • the support projection on its upper side has a ramp for the spring, so that the panels are interconnected by sliding within the laying plane.
  • the panels are according to the principle described above primarily by placing the second panel opposite the first panel connectable. The depositing is done by parallel placement or bending, but at least by lowering in a direction perpendicular to the laying plane from above against the already laid panel.
  • a ramp for the spring on top of the support projection allows at the same time that the panels can be horizontally locked together within the laying plane. The ramp causes the spring of the second panel to be raised. It is harmless that the spring is deformed differently than when depositing from above. It snaps behind the support projection when pushed together horizontally and comes into contact with the support surface.
  • the two adjacent panels are additionally secured by locking strips against a shift within the laying direction. These may also have ramps to slightly raise the adjacent second panel when pushed together horizontally, so that the adjacent panels can be locked together similar to the drop from above.
  • the connecting portion must cause a defined displacement of the locking body.
  • it has on its the support projection facing the bottom of a convex contact area.
  • it is arcuately curved, so that it comes to a point contact or with elongated springs to a line contact with the support projection without any clamping.
  • the connecting portion itself must also have a sufficient displaceability relative to the foot.
  • it has a thickness which increases from its end adjacent to the foot in the direction of its end adjacent to the locking body. The increase in thickness results in particular in that a convex contact region is formed on the underside of the connecting section. Conversely, the area adjacent to the foot may be concave.
  • the foot can basically have a greater thickness than the transition region to the connecting portion.
  • the spring can be constructed overall comb-like.
  • the foot of the spring forms a continuous back.
  • this foot is followed by a plurality of independently displaceable connecting sections and locking bodies, which are connected to one another like individual tines or fingers via the common foot.
  • Such a designed spring can be used as a preconfigured component in the holding and has in particular when bending the second panel relative to the first panel a much higher flexibility.
  • angling is meant that rectangular panels are first inserted into each other in the region of their long sides and then folded by pivoting about the long side in the laying plane.
  • the said springs are arranged, wherein the region of the spring, which is closest to the longitudinal edge, about which the panel is pivoted, first comes into engagement with the other side of the head.
  • a plurality of individual, spaced-apart springs or comb-like springs may be provided.
  • the springs are arranged in a preferred embodiment such that the foot includes a first angle with the connecting portion and the connecting portion with the locking body includes a second angle, wherein both angles in the locked position are greater than the angles in the unlocked position.
  • the spring should be stretched overall and not be upset.
  • the lateral displacements of the connection portion and the lock body add up.
  • This has the advantage that the locking body in the unlocked position can swing back completely or almost completely behind the pressing edge and in the Locked position can deflect relatively far. This allows relatively compact and material-saving springs in contrast to designs in which the joint area between a connecting portion and a locking body to be deflected, as this makes comparatively long locking body or connecting sections required.
  • This may be one or more projections or depressions which engage in matching, in particular opposite, projections or depressions of the locking body.
  • An advantage of this means for positive and / or adhesion is the proximity to the locking groove.
  • the upper groove flank of the locking groove is engaged by the locking body.
  • the means are arranged for positive and / or non-positive locking of the panel.
  • the locking body therefore connects the second panel immediately in the region of the locking edge with the first panel, which in addition contributes to minimizing a vertical offset even with vertical load between the two panels.
  • the means for positive and / or non-positive locking of the locking body are preferably integral parts of the locking body. But it can also be applied materials. Manufacturing technology, it is possible within the scope of the invention to produce the springs in the extrusion process. By coextrusion material pairings can be realized in coordination with the respective functional sections.
  • the transition regions of the connecting portion that is, the joint areas, for example, may be made of more elastic materials, while the foot portion, the connecting portion and also the locking body made of less elastic materials.
  • the springs can have cavities. The cavities can contribute to weight reduction and material savings and give the spring a targeted higher flexibility.
  • the invention provides that the spring in the locked position has a restoring force which is so great that the locking body automatically moves away from the locking edge during unlocking.
  • the restoring force should be permanently maintained. Therefore, preferably no creep-prone materials should be used, especially not in the joint area.
  • the restoring force is built up by the elastic deformation of the spring in the transition from the unlocked state to the locked state. To obtain this restoring force as a tensile stress in the joint area, the joint areas must have a sufficient thickness or at least consist of suitable materials so as not to tire under the permanent tensile load. It is advantageous if the pad can be resumed even after years, wherein the unlocking is not hindered by fatigue in the area of the springs.
  • the panels rectangular or square with typically one head side formed with one of said displaceable springs and the opposite head side with a mating locking groove.
  • the invention also makes it possible that they are not profiled with the said displaceable tongue-forming sides of a panel which comprises a fixed spring tongue which fits into the locking groove for said displaceable spring.

  • the second panel is in the locking position on a support bar, which is located between the top of the first element and its locking groove.
  • the proximity of the support bar to the top causes the forces from the second panel to be introduced into the first panel. Due to the proximity to the upper side, less elastic deformations occur between the panels and thus the lowest possible height offset under the load.

  • FIGS. 5 and 6 show a first panel 51 and a second panel 52 in a sectional view through their connection area.
  • the two panels 51, 52 are positively connected with each other.
  • the left in the image plane panel 51 has a locking bar 53 which engages under the right in the image plane panel 52.
  • an upwardly pointing coupling bulge 54 is formed which engages in a coupling channel 56 which is open towards the underside 55 of the second panel 52. Due to the mutual engagement of the dome bulge 54 and the dome channel 56, a locking of the two panels 51, 52 in the horizontal direction, that is, in the direction of the laying plane V is achieved.
  • the laying plane V runs parallel to the upper side 57 or underside 55 of the two panels 51, 52.
  • the vertical alignment of the two panels 51, 52 is achieved via a support strip 58 on the first panel 51.
  • the support strip 58 is located above a marginal open locking groove 59 in the first panel 51.
  • the second panel 52 rests on the support bar 58 so that forces acting from above in the direction of the arrow P can be introduced from the second panel 52 into the first panel 51 ,
  • the locking groove 59 serves to receive a movable spring 60.
  • the spring 60 is held in a retaining groove 61.
  • the retaining groove 61 is also open towards the edge side of the second panel 52 and faces the locking groove 59.
  • the groove flanks of the retaining groove 61 extend parallel to one another and are at an angle to the laying plane V.
  • the groove flanks of the retaining groove 61 rise towards the groove bottom.
  • a Nutmündung the locking groove 59 is thus located at a greater distance from the top 57 of the second panel 52 as the Nuttiefste.
  • the spring 60 is held in the retaining groove 61 by a foot 62.
  • the foot 62 is adjoined outside the holding groove 61 by a connecting portion 63, which in turn is followed by a locking body 64.
  • the connecting portion 63 is angled relative to the foot 62 and has obliquely downward toward the bottom 55 of the second panel 52nd

  • the spring blank 65 which already has the foot 62 so that the spring 60 can be inserted into the retaining groove 61, is attached to the second panel 52. In this position, the spring blank 65 is machined in the installed position to its final configuration. The shaded area of the spring blank 65 is removed, so that the spring 60 receives its final contour, as in FIG. 6 is shown. At the same time, the edge region of the panel 52 can also be machined.
  • the locking body 64 must be pivoted to lock the panels 51, 52 in the image plane upwards.
  • the spring 60 is supported during locking on a support projection 66, while the free end 67 of the locking body 64 is pressed behind a locking edge 68 on the support strip 58.
  • additional means 70 for positively locking the locking body 64 relative to the second panel 52 are provided adjacent to the pressing edge 69.
  • These locking means 70 consist of serrated projections facing the locking groove 59.
  • the means 70 for locking are just like the pressing edge 69 at a distance perpendicular to the laying plane V and thus at a greater distance from the top 57 of the panels 51, 52 as the pressing edge 69.
  • the locking body 64 is slipping out of the locking groove 59th prevented.
  • the means 70 are arranged for positive locking on the second panel 52, and the free end 67 of the locking body 64 has corresponding means 71 for positive locking.
  • the corresponding means for locking are configured in the same way and lead to an undercut, which prevents the panel 52 at a displacement vertical to the laying plane V.
  • the respective means for locking perpendicular to the laying plane V are effective.
  • FIG. 7 shows an embodiment similar to that of the FIG. 5 , Therefore, the reference numerals introduced there have been copied identically. Only the spring 60a and the support projection 66a are configured slightly differently. Unlike the spring 60 in FIG. 5 has a the foot 62 facing away from flank 72 of the spring 60 a no straight, but a rounded cross section, so that a recess is formed. The flank 72 can also be referred to as concave rounded.
  • the supporting projection 66a comes into contact with the opposite side of the connecting portion and pushes it away from the retaining groove 61, as can be seen from the gap formation between the supporting projection 66a and the panel 52 in the region of the rear edge of the connecting portion 63.
  • FIG. 5 Referring to which further details of the connection have been explained.
  • FIG. 8 again shows the initial position of the spring 60a before locking, with the comments to FIG. 6 Reference is made.
  • the difference from the spring 60 in FIG. 6 is the concave configuration of the edge 72 at the connecting portion 63 of the spring 60 a.
