Description

  • 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. Conventionally, 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.
  • It is known to form mechanical locking means on the grooves and springs, which engage with one another in a floor covering adjacent panels in latching engagement. As a result, a joint formation caused by expansion or shrinkage operations should be avoided. At the tongue and groove of the panels are matched locking elements in the form of recesses, recesses or projections formed to hold the panels in the assembled position glueless. In general, the panels are rotated along their longitudinal sides into each other or clicked and then moved laterally, so that locking strips on the head sides engage.
  • There are also solutions in which the abutting head sides are connected by displaceable springs. The WO 2011/012104 A2 describes such a system of mechanically interconnectable panels. In this system, the mutually complementary sides each have a groove with different lengths of upper and lower groove cheeks. In one of the grooves, a spring is held. The protruding from the groove part of the spring is displaced and intended to engage in the corresponding groove of the adjacent panel. For this purpose, the spring has a projection which abuts when joining the longer groove cheek of the other panel. As a result, the spring is moved so that it engages in the assembled position in the adjacent groove and locks the two panels together. In this system, the free end of the spring is pushed into the adjacent groove.
  • 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.
  • While the difficulty in unfolding the spring is to accurately insert the free end of the spring into the locking groove of the adjacent panel in a pivoting motion, the challenge in folding the spring therein is to locate the free and relatively narrow protruding toward the top of the panel To grip the end firmly during the joining and to press down when the panel is laid down. This is only possible with a drop from above. A lateral pushing together of the panels is not possible with this operating principle.
  • Proceeding from this, 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.
  • This object is achieved in a covering with the features of claim 1. Advantageous developments of the invention are the subject of the dependent claims.
  • The covering of mechanically interconnectable panels is characterized by the following features:
    • a) The panels have at their sides to be joined to a corresponding profiling, via which adjacent first and second panels are locked together when assembled;
    • b) the locking is effected by at least one spring, which is held on the second panel in a retaining groove and which in the joining movement is partially pivotable behind a locking edge of a locking groove of the adjacent first panel;
    • c) the spring comprises a foot held in the retaining groove and outside the retaining groove a connecting portion adjoining the foot and a locking body adjoining the connecting portion for engagement with the adjacent panel;
    • d) The locking groove has a shorter upper groove flank with the muzzle-side locking edge and a longer lower groove flank with an end-side support projection having an inclined to the locking groove support surface on which the spring during locking is supported, so that the locking body during assembly of the panels in the direction of the locking groove is displaced;
    • e) The second panel has a projecting pusher edge adapted to press the latch body against the support surface during assembly of the panels and to urge behind the latch edge of the latch groove, the latch edge being in the latched position from an upper side of the first panel considered a greater distance than the locking edge has.
  • 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. To guide the locking body is used on the one hand inclined to 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. The term "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. The support surface is inclined so that the connecting portion of the spring is pushed upwards. 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.
  • While 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. By pushing the connecting body upwards alone, however, 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. When assembling the panels so the transition region between the locking body and the connecting portion is pressed upwards towards the pressing edge. The locking body must evade the pressing edge inevitably. However, 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. In order to solve this problem, it is provided according to the invention that, viewed in the locked position from an upper side of the first panel, the pressing edge has a greater distance than the locking edge. The pressing 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 area. 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 strong profiling 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.
  • The term "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. B. a chamfer or rounding act. 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, substantially horizontally oriented retaining grooves with open to the side of the panels Nutmündungen offer. In principle, however, it is also conceivable that the retaining groove runs perpendicular to the laying plane and is 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.
  • 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 exerts a force towards the top of the first panel on the upper groove flank of the locking groove. 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.
  • In a further advantageous embodiment of the invention, the free end of the locking body is substantially triangular. In this case, 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 designed correspondingly short. To fix the spring, it is sufficient to exert a force targeted to the acting between the groove flank and groove bottom corner region. 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 can not 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. In the case of 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. In the further course to the connecting portion of the spring out the cross section of the locking body is preferably tapered to allow a 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 invention provides in a further embodiment, that 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. However, 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.
  • During locking, the connecting portion must cause a defined displacement of the locking body. For this purpose, it has on its the support projection facing the bottom of a convex contact area. In particular, 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. For this purpose, 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. Here, the foot of the spring forms a continuous back. In this case, 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. By 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. In the head region of these panels, 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. In order to avoid twisting of the spring, 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. In other words, the spring should be stretched overall and not be upset. In this configuration, 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 can deflect relatively far in the locked position. 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.
  • In a further embodiment, at the free end of the locking body perpendicular to the laying plane effective means for positive and / or non-positive locking of the locking body relative to the second element are arranged. Conversely, adjacent pressing edges and the locking groove facing, perpendicular to the laying plane effective means for positive and / or non-positive locking of the locking body relative to the second element to be arranged. In this context, perpendicular to the laying level effectively means that the locking body is not displaced perpendicular to the laying plane, due to the positive and / or frictional connection between the locking body and the second element. This can be achieved in the case of a positive connection by undercuts. These are therefore arranged on the sides of the panels facing areas of the panel. 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. In the immediate vicinity, namely on the front side of the panel in question 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.
  • With correspondingly elastic materials in the region of the panel or the locking body even frictional connections, similar to a snap effect, can be realized.
  • 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.
  • With regard to the overall configuration, it is possible to make 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. In the context of the invention, however, it is also possible to equip the sides adjacent to this side with said springs in such panels. That is, the two other sides are provided with the mating locking grooves. This allows greater freedom of installation, especially in the case of square panels.
  • 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. In the case of a square panel, for example, one side could be provided with the said spring and the side adjacent to the corner could be provided with a fixed spring tongue. The two other sides are provided with both the spring tongue and the displaceable spring matching locking grooves. This configuration also allows greater freedom when laying the panels.
  • In a preferred embodiment of the invention, 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 is located. 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. At the same time, the first panel is held either by the pressure of the displaceable against the upper groove flank of the locking groove or if a fixed spring tongue is provided, held by the pressure against the upper groove flank. The first panel is to some extent clamped by the area between the support ledge and the upper groove flank of the second panel.
  • The inventive concept is applicable to all floor, wall and ceiling systems in which a topping on a support, which is in particular a wood-based panel, such as an MDF, HDF or chipboard is arranged, such as real wood flooring, laminate , Carrier with painted surfaces as a topping, linoleum, cork on support plates etc .. The cover layer may in particular consist of a decorative paper with overlay, which determines the appearance of the elements. A floor covering may thus be a finished parquet floor, a real wood floor or a laminate floor. Likewise, elements of solid material, such as. As wood flooring, wood elements, molded or injection molded plastic plates, especially PVC moldings or gypsum boards. The springs for the panels can be used in particular for panels with a particularly small thickness of, for example, 4 mm to 8 mm. The panels may be, inter alia, panels for PVC floors, for example, PVC-based top panels, as well as plastic or cement-based panels. The individual panels can be reinforced by fibers.
  • The covering according to the invention enables click connections, which can be produced both by swiveling in (fold-down) and by vertically depositing from above as well as by horizontally telescoping or wrapping. The covering according to the invention is equally suitable for rectangular panels as well as for square panels or design installations in which cross joints are formed. This results in a much greater variety of design for this type of so-called Klickpaneele. Thus, the invention is not limited to the fact that the panels are rectangular and in particular not to the fact that the panels of two adjacent rows are arranged offset from one another. The invention will be explained in more detail with reference to embodiments schematically illustrated in the drawings. Show it:
  • 1 and 2 a cross section through the connecting region of two adjacent panels in different mounting positions, wherein 1 the still unlocked position shows and 2 represents the locking position;
  • 3 and 4 a cross section through the connecting region of two adjacent panels in a further embodiment of the profiling;
  • 5 a cross section through the connecting region of two adjacent panels in another embodiment in the locking position;
  • 6 a cross section through a panel with a still unprofiled spring;
  • 7 a cross section through the connecting region of two adjacent panels in another embodiment in the locking position;
  • 8th a cross section through a panel with a still unprofiled spring and;
  • 9 a cross section through the connecting region of two adjacent panels in a further embodiment of the profiling.
  • 1 shows a cross section through the connecting region of two panels 1 . 2 , The panels 1 . 2 are configured so that they can be assembled into a floor covering, in particular a floor covering. The panels 1 . 2 have an underside facing the panel background 3 as well as a top 4 which corresponds to the visible side. The illustration shows a left first panel 1 and on the right a second panel 2 before the connection of the two panels 1 . 2 , The second panel 2 points to the first panel 1 pointing page 5 a feather 6 in a holding groove 7 on. The feather 6 is intended to be in a locking groove 8th on the first panel 1 intervene. The locking groove 8th is located below a support rail 9 that as a lead on the side 10 of the first panel 1 is trained. The support strip 9 runs parallel to the laying plane V, passing through the top 4 of the first panel 1 is defined. On the side 5 of the second panel 2 is formed a corresponding recess, so that the second panel 2 near its top 4 perpendicular to the laying plane V on the first panel 1 is supported.
  • The first panel 1 also has a locking strip 11 on and the second panel 2 a downwardly open dome channel 12 and one yourself hereby towards the pen 6 subsequent, downward dome bulge 13 , The locking bar 11 of the first panel 1 stands opposite the side 10 farthest ago. The second panel 2 will be so opposite the first panel 1 arranged that when lowering in the direction of arrow P of dome bulge 13 of the second panel 2 with a dome channel 14 the locking bar 11 and the dome channel 12 of the second panel 2 with a dome bulge 37 the locking bar 11 engaged. This area of the panels 1 . 2 essentially serves for positional orientation in a horizontal representation, whereby horizontally in the context of the invention the laying plane V corresponds.
  • The deposition in the direction of the arrow P can be done by the top 4 of the second panel 2 is displaced parallel to the laying plane V. Just as well can the second panel 2 be bent by pivoting about a non-illustrated longitudinal edge. The cutting plane of the 1 is chosen so that the spring 6 straight with the first panel 1 comes into contact. In the plane parallel to the image plane cutting planes is the spring 6 when bending (fold-down) either already deformed or not yet in contact with the first panel 1 ,
  • It is noted that the dome bulge 37 on the locking bar 11 as well as the downwardly projecting Kuppelwulst 13 on the second panel 2 each have a sloping top or bottom, so that even when pushing the panels together 1 . 2 in the laying plane V, that is, by horizontally pushing together, the Kuppelwulst 13 of the second panel 2 at the dome bulge 37 of the first panel 1 slides off, while the second panel 2 raises until the two panels 1 . 2 about the in 1 reach the position shown. The panels 1 . 2 Therefore, they can be connected to each other not only by vertical placement or angling, but also by horizontal telescoping in the direction of the laying plane V.
  • Essential part of the connection between the two panels 1 . 2 is the spring 6 as well as the interaction with the profiling in the area of the pages 5 . 10 the panels 1 . 2 , The feather 6 is built in three parts. It is made of plastic and has a foot 15 , The foot 15 is trapezoidal configured to match the retaining groove 7 , The holding groove 7 is opposite the outermost edge of the panel 2 set back.
  • Outside the holding groove 7 is the second component of the spring 6 a connecting section 16 , To the connecting section 16 in turn closes a locking body 17 at. The thickness of the connection section 16 takes his foot off his 15 adjacent end 18 towards his, the locking body 17 adjacent end 19 towards. This is also due to the fact that on the locking body 17 adjacent end a bottom 20 of the connection section 16 a convex contact area 21 has. The convex contact area 21 comes when lowering the second panel 2 in contact with a supporting projection 22 , The support projection 22 has one to the locking groove 8th inclined support surface 23 which is concavely curved. This allows the convex contact area 21 on the bottom 20 of the connection section 16 easy on the support projection 22 slide off, leaving the bottom end 19 of the connection section 16 relative to the foot 15 the feather 6 is shifted upwards.
  • The connecting section 16 points in the unlocked position almost perpendicular to the bottom 3 and is only slightly towards the locking groove 8th inclined. However, this tendency reaches out so that the connecting section 16 guided only in one direction can be shifted. The one between the foot 15 and the connection section 16 included angle W1 ( 2 ) is increased when lowering, as in a comparison of 1 and 2 can be seen. 2 shows the arrangement of 1 in locked position.
  • 1 further shows that the locking body 17 together with the locking portion 16 describes a U-shape. The locking body 17 shows in the unlocked position approximately at 45 ° angle obliquely above. It lies approximately parallel to the groove mouth of the locking groove 8th , He is as long as the Nutmündung is wide. He is in the realm of his free end 24 configured essentially triangular with rounded tip, with an upper flank 25 of the triangular end 24 intended for this purpose, with a pressure edge 26 on the second panel 2 to get in touch. The pressing edge 26 slides when lowering the second panel 2 on the upper flank 25 along to the press edge 26 into a depression 27 attacks. This will be the free end 24 along an insertion slope 28 at the first element 1 until behind a locking edge 29 the locking groove 8th pressed. To the locking edge 29 closes the upper groove edge 30 the locking groove 8th at. The upper groove flank 30 is in comparison to the multiply longer lower groove flank 31 the locking groove 8th very short. The lower groove flank 31 extends over into the support surface 23 and ends in the transition area to a top 32 the support projection 22 , The top 32 is at an angle to the laying plane V and serves as a ramp for the spring 6 if the panels 1 . 2 to be interconnected by moving within the laying level V.
  • 2 shows the two panels 1 . 2 in the locked position. It can be seen that the pressing edge 26 now in the depression 27 on the top 32 of the locking body 17 summarizes. The free end 24 of the locking body 17 now grabs the locking groove 8th so that the locking body 17 on the one hand on the upper groove flank 25 behind the locking edge 29 is applied. One of the top of the triangular end 24 opposite lower flank 34 lies at least partially on the bottom of the groove 35 the locking groove 8th at. The groove bottom 35 runs perpendicular to the laying plane V.
  • 2 also shows that of the foot 15 and the connection section 16 included angle W1 relative to the initial position in 1 is enlarged. The same applies to the angle W2 between the connecting section 16 and the locking body 17 is included.
  • 2 further shows that the locking body 17 no longer out of the locking groove 8th can be shifted, because the pressure edge 26 at a greater distance A1 to the top of the interlocked panels 1 . 2 is arranged as the locking edge 29 , which is located at a distance A2. This causes the pressure edge 26 in front of the locking groove 8th and no longer laterally or above the locking groove 8th , In the locking position, the pressing edge acts 26 therefore not only from above in the direction of the arrow P on the locking body 17 but blocks a horizontal shift. The pressing edge 26 prevents the angle W2 between the connecting section 16 and the locking body 17 downsized again. In other words, the press edge stops 26 the feather 6 in the spread position, as in 2 is shown and ensures as a locking body, the permanent locking of the two panels 1 . 2 ,
  • The 3 and 4 again show the two panels 1 . 2 , The left in the image plane panel corresponds in its marginal profiling exactly the panel of 1 and 2 , The right in the image plane panel is in contrast to the embodiment of 1 and 2 not with a displaceable spring 6 provided, but with a fixed or rigid spring tongue 36 , Such a rigid spring tongue 36 For example, in the case of a rectangular panel at an adjoining corner adjacent side to those in the 1 and 2 be provided pages shown. This is particularly advantageous for square panels, since then results in a greater freedom of design when laying. The right-hand panel in the picture plane 2 can be moved in the direction of the arrow P2, that is, within the laying plane V, so that the fixed spring tongue 36 behind the locking edge 29 grips and into the locking groove 8th attacks. Due to the additional horizontal locking in the area of the locking strip 11 that is, the mutual engagement of the dome bulges 13 . 37 in the associated Kuppelnuten 12 . 14 , results in a positive connection in the horizontal direction, that is within the laying plane V. Regarding the further function in the area of the support strip 9 and the interaction in the area of the locking bar is on the versions too 1 Referenced, since the said components have already been explained there. The only difference between the embodiments of the 3 and 1 is the fixed spring tongue 36 compared to the displaceable spring 6 ,
  • The 5 and 6 show a first panel 51 and a second panel 52 in a sectional view through its connection area. The two panels 51 . 52 are positively connected with each other. For this purpose has the left panel in the image plane 51 a locking strip 53 , which is the right-hand panel in the picture plane 52 engages below. At the locking bar 53 At the end is an upward facing dome bulge 54 Trained in one to the bottom 55 of the second panel 52 open dome channel 56 attacks. Through the mutual engagement of the Kuppelwulstes 54 and the dome channel 56 becomes a lock of the two panels 51 . 52 in the horizontal direction, that is, in the direction of the laying plane V achieved. The laying level V is parallel to the top 57 or bottom 55 the two panels 51 . 52 ,
  • The vertical alignment of the two panels 51 . 52 is about a support bar 58 on the first panel 51 reached. The support strip 58 is located above a locking groove open at the edge 59 in the first panel 51 , The second panel 52 lies on the support strip 58 on, so that acting from above in the direction of the arrow P forces from the second panel 52 in the first panel 51 can be initiated. The locking groove 59 serves to accommodate a movable spring 60 , The feather 60 is in a holding groove 61 held. The holding groove 61 is also to the edge of the second panel 52 towards open and points to the locking groove 59 , The groove flanks of the retaining groove 61 run parallel to each other and are at an angle to the laying plane V. The groove edges of the retaining groove 61 climb to the bottom of the valley. A Nutmündung the locking groove 61 is therefore located at a greater distance from the top 57 of the second panel 52 as the Nuttiefste. The feather 60 is with one foot 62 in the holding groove 61 held. At the foot 62 closes outside the holding groove 61 a connecting section 63 on, in turn, a locking body 64 follows. The connecting section 63 is opposite the foot 62 angled and points diagonally down towards the bottom 55 of the second panel 52 ,
  • 6 shows the starting position of the spring 60 before locking. The in 6 created part is intended to illustrate that the spring 60 out a larger spring blank 65 is made. The spring blank 65 who already has the foot 62 has, so that the spring 60 in the holding groove 61 can be used is on the second panel 52 appropriate. In this position, the spring blank 65 machined in the installation position to its final configuration material. The hatched area of the spring blank 65 is removed, leaving the spring 60 get their final contour as they are in 6 is shown. At the same time, the edge area of the panel 52 can also be machined.
  • From the 5 and 6 it becomes clear that the locking body 64 for locking the panels 51 . 52 must be pivoted upward in the image plane. Here, the spring is supported 60 while locking on a support projection 66 on, while the free end 67 of the locking body 64 behind a locking edge 68 on the support strip 58 is pressed. The special here is that adjacent to the pressing edge 69 additional funds 70 for the positive locking of the locking body 64 opposite the second panel 52 are provided. These funds 70 for locking consist of serrated projections, the locking groove 59 point. The means 70 to latch as well as the pressing edge 69 at a distance perpendicular to the laying plane V and thus at a greater distance from the top 57 the panels 51 . 52 as the pressing edge 69 , As a result, the locking body 64 on slipping out of the locking groove 59 prevented. In the same form as the funds 70 for positive locking on the second panel 52 are arranged, also has the end portion 57 of the locking body 64 corresponding funds 71 for positive locking. The corresponding means for locking are configured opposite and lead to an undercut, which the panel 52 at a displacement vertical to the laying plane V prevents. Thus, the respective means for locking perpendicular to the laying plane V are effective.
  • 7 shows an embodiment similar to that of the 5 , Therefore, the reference numerals introduced there have been copied identically. Only the spring 60a and the supporting projection 66a are configured slightly differently. Unlike the spring 60 in 5 owns one's foot 62 remote flank 72 the feather 60a not a straight, but a rounded cross-section, so that a recess is formed. The flank 72 can also be called concave rounded.
  • The support projection 66a comes into contact with the opposite side of the connecting portion and presses it from the retaining groove 61 away, as based on the gap formation between the support projection 66a and the panel 52 in the region of the rear edge of the connecting portion 63 can be seen. In addition, the explanation of the 5 Referring to which further details of the connection have been explained.
  • 8th again shows the starting position of the spring 60a before locking, referring to the explanations to 6 Reference is made. The difference from the spring 60 in 6 is the concave configuration of the flank 72 at the connecting section 63 the feather 60a ,
  • 9 again shows the panels 51 . 52 , The left panel in the picture plane 51 corresponds in its marginal profiling exactly the panel of 7 , The right-hand panel in the picture plane 52 is unlike the appearance of the 7 not provided with a displaceable spring, but with a rigid spring tongue 73 , The representation in 9 is in relation to 8th the counterpart to the representation of the 4 in terms of the 1 and 2 , Accordingly, such a rigid spring tongue 73 For example, in the case of a rectangular panel at an adjoining corner adjacent side to the in 7 be provided side. In the same way as in the embodiment in the 4 grips the spring tongue 73 in the locking groove 59 , Due to the additional horizontal locking in the area of the locking strip 53 that is, the mutual engagement of the dome bulge 54 in the dome channel 56 results in a positive connection in the horizontal direction, that is, within the laying plane V. Regarding the other functions in the area of the support strip 58 and the interaction in the area of the locking strip 53 will apply to the comments 5 Referenced.
