Description

  • The invention relates to a panel, comprising a panel top and a panel bottom and at least four panel edges, which face each other in pairs, with matching at the panel edges complementary retaining profiles that match such that similar panels are fastened together, wherein at least one of the retaining profile pairs provided with hook profiles is, namely on a panel edge with a receiving hook and on the opposite panel edge with a locking hook.
  • With such panels, for example, floor coverings are made, in particular, such panels are suitable for floating floor coverings. The panels usually have decorative surfaces.
  • The proposed panel should be suitable for interlocking according to the "fold-down method". For this method, a Paneelart is used in which one of the retaining profile pairs is provided with a modified tongue and groove profile, while the other pair of retaining profile is provided with the hook profiles according to the invention. For the fold-down method, a new panel is angled and preferably brought with its spring profile edge to the groove profile edge of a horizontal panel or a row of panels. Subsequently, the new panel is pivoted down into the plane of the assembled panels, thereby positively locking the spring profile locked with the groove profile. During the mentioned swing-down movement, a positive locking of the hook profiles is generated at the same time because one of the hook profiles moves like a scissor toward the other hook profile and positively engages with it. There is a lock instead.
  • In addition, the proposed hook profiles are also suitable for a push-down locking. For a push-down latch, all the panel pairs of panels need to be connected by a vertical movement, i. for example, by a lowering movement of a panel, namely in a direction perpendicular to the panel top direction (vertical). The fold-down method is then not applicable.
  • In practice it happens that a panel can not be locked at the end of a panel row because a wall in the way and the panel is too long. In order to close the gap in the floor, it is common to use a panel e.g. cut with a saw to cut it to the required length. As a rule, a new row of panels can be started with the separated residual piece of the panel. Basically, the complementary retaining profiles of a severed panel always fit together. In principle, therefore, complementary retaining profile edges of a severed panel can be locked together.
  • The WO 01/02670 proposes different hook profile pairs. The hook profiles are intended to prevent horizontal pulling apart of the panels, ie in the panel plane and perpendicular to the locked panel edges. However, it appears in a load in said horizontal direction that the strength of the hook profiles is unsatisfactory.
  • Other panels with hook profile pairs are from the WO 2010/143962 A1 known. The various embodiments of this prior art suffer from the fact that the hook profile pairs, if they can be pulled apart in the panel plane and perpendicular to the locked panel edges. This is especially true when the panels are made of engineered wood material consisting of wood particles or fibers bonded to a panel material with a binder.
    The prior art forms the publications DE 10 2011 086 846 A1 . WO 2012/001503 A1 . WO 03/016554 A1 . DE 10 2011 121 348 A1 and DE 10 2011 104 718 A1 , It is in particular from DE10 2011 086 846 A1 discloses a panel comprising a panel top and a panel bottom, and at least four panel edges facing each other in pairs with complementary retaining profiles provided in pairs at the panel edges to mate similar panels together, at least one of the pair of retaining profiles being provided with hook profiles; namely on a panel edge with a receiving hook and on the opposite edge of the panel with a locking hook, the receiving hook has a receiving panel directed to the top panel and an open to the panel top receiving groove and the locking hook is provided with a directed towards the bottom panel locking edge and a bottom open to the panel locking groove, wherein the receiving edge has an inner side, which faces the receiving groove, and this inner side serves as a lower locking surface, and matching the Arretierrand has an inner side, which the Arreti is facing, and this inner side serves as a corresponding upper locking surface, with the proviso that both the upper locking surface and the lower locking surface are each inclined relative to the Lot on the panel top so that they are aligned parallel to each other in the locked state and touch can, with the inclination of the Locking surfaces is selected so that the normal vector on the lower locking surface intersects the panel top and the normal vector on the upper locking surface intersects the panel bottom, wherein a lower latch is provided, which comprises a first latching means, which is arranged on an outer side of the receiving edge, and lower latching a corresponding thereto second latching means, which is arranged on a recessed groove flank of the locking groove.
  • In view of this, the Applicant is seeking a panel with an improved hook profile pair.
  • The invention proposes for this purpose that
    at least a planar portion of the top of the receiving edge is inclined downwardly towards the outside of the receiving edge, wherein at least a planar portion of the groove bottom of the locking groove is adapted in a complementary manner to the inclination of the top of the receiving edge, wherein the receiving hook, a transition from the top of the receiving edge is provided in the lower locking surface, wherein this transition is formed as a curvature, and wherein between the portion of the groove base and the upper locking surface a transition is provided, said transition is a curvature forming a throat.
  • The normal vector is directed in the sense of the invention in each case by the corresponding locking surface perpendicular to the outside (not directed into the panel material). The normal vector includes, with the respective panel side which it intersects, in each case an angle which is the same as the angular dimension by which the locking surfaces are inclined with respect to the perpendicular on the panel top side (change angle). The inclination of the locking surfaces relative to the solder on the top of the panel may be in an angular range α of 4 ° to 50 °. Preferably, the angle α is in a range of 5 ° to 30 °, and more preferably in a range of 5 ° to 15 °.
  • The panel is preferably made of a wood material, such as HDF, MDF or OSB, which in a broader sense also WPC materials (wood plastic composite) fall under it. Because of the locking mechanism presupposes a certain elasticity, in particular in the region of the first and thus corresponding second locking means, said materials are suitable because of their certain elasticity. Alternatively, the panel material may also be a plastic, as in the case of LVT (luxury vinyl tiles) products, for example, because this plastic also has some elasticity.
  • The portion of the groove bottom of the locking groove and the portion of the top of the receiving edge can be aligned parallel to each other in the locked state.
  • The receiving groove of a hook profile is such that the locking edge of the complementary hook profile fits into the receiving groove and the locking groove of the complementary hook profile is such that the receiving edge of a hook profile fits into the locking groove.
  • A further development provides that the first latching means of the lower latching has a latching projection, and that the second latching means of the lower latching has a mating latching recess.
  • Alternatively, the first locking means of the lower latching a latching recess and that the second latching means of the lower latching have a mating latching projection.
  • It may also be useful if an upper latching is provided which has a first latching means on an outer side of the arresting edge, and a second latching means corresponding thereto is provided on a recessed groove flank of the receiving slot.
  • The first latching means of the upper latching arrangement expediently has a latching projection and that second latching means of the upper latching mechanism has a matching latching recess.
  • Alternatively, the first locking means of the upper latching a locking recess and that the second locking means of the upper latching have a mating latching projection.
  • A further benefit is obtained if at least one free space is provided between the underside of the arresting edge and the groove bottom of the receiving groove. The space can absorb dirt particles or other loose particles. For panels made of wood-based materials, for example, particles can detach from the panel edge, which should not settle between joining surfaces of the hook profiles. Otherwise they could hinder a positionally correct locking of the hook profiles.
  • Moreover, it is useful if in the locked state, a gap between the outside of the receiving edge and groove flank of the locking groove is provided.
  • Conveniently, an underside of the Arretierrand in the locked state at least partially touches the groove bottom of the receiving groove. If a load presses on the panel top in the region of the arresting edge, the arresting edge can bear this load because its underside is supported on the groove bottom of the receiving groove of the receiving hook.
  • The curvature provided on the receiving edge provides edge protection. It can also serve to guide the locking edge when it comes into contact with the curvature. Thus, the Arretierrand along the curvature is moved down into the receiving groove.

  • Fig. 1 shows a perspective fold-down method for locking panels according to the prior art. In this case, a new panel 1 is angled obliquely with a spring profile edge 2 advanced to a Nutprofilkante 3 of a lying panel 4 a previous row of panels. Subsequently, the new panel 1 is pivoted down into the plane of the assembled panels, wherein in the same row of panels an identical panel 5 already lies. Due to the pivoting joining movement, the tongue and groove edge lock together. The new panel 1 also has a pair of hook profiles, namely a receiving hook (not shown) and a locking hook 6. During the pivoting-down joining movement of the locking hook 6 of the new panel 1 is like scissors in the direction of the complementary receiving hook 7 of the identical panel 5 moves. In this case hooks the locking hook 6 with the receiving hook 7 and at the same time with the locking of tongue and groove profile edge is a positive locking of the hook profiles vonstatten.
  • According to Fig. 1 the structure of a floor surface is indicated. In this example, a new panel is always applied to the left continuously.
  • Fig. 2 shows a second example of a known in the art fold-down method for locking panels. It is different from the method of Fig. 1 only in that a new panel must be applied continuously to the right, ie the panel edges, which have the receiving hook or the locking hook are compared to the example of Fig. 1 been swapped.
  • Tongue and groove profiles, which are suitable for a positive locking by means of the fold-down method, are well known in the art, for example from the WO 97/47834 A1 or off WO 00/63510 ,
  • Fig. 3 illustrates a first embodiment of a panel 1 according to the invention with a panel top 1a and a panel bottom 1b, wherein simplified only one pair of retaining profile of the panel is shown. The one shown here Retaining profile pair has complementary hook profiles, namely a locking hook 6 (top) and a receiving hook 7 (bottom). To explain the operation you can imagine the panel 1 cut in two parts, so that the two hook profiles (6 and 7) of the panel can be hooked together. Hook profiles of identical panels are of course locked in the same way.
  • The receiving hook 6 has a receiving edge 8 directed towards the panel top 1a and a receiving groove 9 which is open towards the panel top. The locking hook 7 is provided with a locking edge 10 directed towards the panel bottom 1b and with a locking groove 11 which is open towards the panel bottom 1b.
  • An inner side of the receiving edge 8 is facing the receiving groove 9 and this inner side serves as a lower locking surface 12. Fittingly, the locking hook 7 forms an upper locking surface 13 on an inner side of its locking rim 10 facing the locking groove 11, which cooperates with the lower locking surface 12 of the receiving rim 8 ,
  • It is both the lower locking surface 12 and the upper locking surface 13 each inclined relative to the Lot L on the panel top by an angle α. The inclinations are aligned with each other, so that the corresponding locking surfaces 12 and 13 are aligned in the locked state parallel to each other and can touch.
  • In addition, the inclination of the lower locking surface 12 is selected so that the normal vector N 12 , which is directed from the lower locking surface 12 perpendicular to the outside, the panel top 1a intersects. Conversely, the normal vector N 13 on the upper locking surface 13 is directed vertically outwards, so that this normal vector N 13, the opposite panel underside 1b cuts. General that the Paneeloberseite 1a and the normal vector N 12 enclose an angle which is as large as the above-mentioned angle α (changing angle). Applies, The same applies to the underside of the panel, which includes an equal angle (change angle) with the normal vector N 13 .
  • With a bottom 10a of the Arretierrands 10 of the locking hooks 7 sits firmly on a groove bottom 9a of the receiving groove 9 of the receiving hook 6. If a load on the panel top 1a presses in the region of the Arretierrand 10, the Arretierrand 10 can carry this load, because its bottom 10a on the groove bottom 9a of the receiving groove 9 is supported.
  • Another function of the hook profiles is to counteract a height offset of the locked panel edges. For this purpose, a lower catch 14 is provided. This comprises on the receiving hook 7, a first locking means in the form of a protruding latching projection 15. The latching projection 15 is arranged on an outer side 8a of the receiving edge 8. Correspondingly, a second latching means in the form of a latching recess 16 is provided on the locking hook 7. The detent recess 16 is arranged on a recessed groove flank 11 a of the locking groove 11.
  • On the receiving hook 6, a portion 8b of the top of the receiving edge 8 has a downward slope, namely falling in the direction of the outside 8a of the receiving edge. Matching is on the locking hook 7, a portion 11b of the groove bottom of the locking groove 11 in a complementary manner adapted to the inclination of the portion 8b of the top of the receiving edge 8. In the locked state, the inclined sections 8b and 11b of receiving edge top side and Arretiernutgrund are aligned parallel to each other.
  • In addition, on the receiving hook 6, a transition from the upper side 8b of the receiving edge 8 to the lower locking surface 12 provided. The transition is formed as a curvature 17. The curvature 17 is a radius in the present example. Also, a transition with a curvature 18 between the portion 11 b of the groove bottom of the locking groove 11 and the upper locking surface 13 is provided on the locking hook 7. The curvature 17 on the receiving edge provides an edge protection and a guide surface. The edge protector is stronger than the protective effect of a phase which has the same width and height as the curvature 17. The curvature 18 forms a throat. It has a radius in the present example and serves the stability in the transition region from the upper locking surface 13 to the groove bottom of the locking groove eleventh
  • According to Fig. 4 are the hook profiles made Fig. 3 shown in the locked state. The latching projection 15 of the receiving hook 6, which is arranged on the outer side 8a of the receiving edge 8, engages positively in the latching recess 16, which is arranged on the recessed groove flank 11a of the locking groove 11. The lower catch 14 counteracts a height offset of the two panel tops 1a, ie a movement apart of the panel edges perpendicular to the panel surface is counteracted. A closed joint F also forms in the horizontal direction on the panel surface 1a. An outer side 10b of the arresting edge 10 is in contact with a recessed groove flank 9b of the receiving groove 9 in this joint.
  • Between the inclined portion 11b of the groove bottom of the locking groove and the inclined portion 8b of the top of the receiving edge 8, a gap 19 is present. This favors it to avoid a height offset at the joint F of the panel top 1a. In addition, the gap 19 provides a certain compliance of the locking hook 7. It has a place with its smallest thickness, which is located where the locking groove 11 is the lowest. The thus gained Compliance can be used because the gap creates 19 space in which a deformation can take place.
  • Fig. 4a shows a detail that enlarges a section that is in Fig. 4 with IVa is noted. In Fig. 4a the latching projection 15 is provided on the receiving hook 6, namely on the outer side 8a of the receiving edge 8. The latching recess is provided on the locking hook 7 and there on a recessed groove flank 11a of the locking groove eleventh
  • In an alternative, which in the clipping according to Fig. 4b is shown, the positions of locking recess and locking projection are reversed. Here, a latching recess 15a is arranged on the receiving hook 6, specifically on the outer side 8a of the receiving edge 8. A latching projection 16a is then provided on the locking hook 7, namely provided on its recessed groove flank 11a of the locking groove 11.
  • Another embodiment proposes a panel with special hook profiles Fig. 5 in front. This goes from the embodiment of FIGS. 3 and 4 out. From this it differs by an additional upper latching 20. The upper latch 20 has on the locking hook 7, a first locking means in the form of a latching projection 21, which is arranged on the outer side 10b of the Arretierrands 10. It acts together with a corresponding second locking means on the receiving hook 6, which is provided on the set-back groove flank 9b of the receiving groove 9. The second latching means forms a latching recess 22, as best in the cutout according to Fig. 5a can be seen. Fig. 5a magnifies the detail that is in Fig. 5 with Va is designated.
  • In an alternative, in the clipping according to Fig. 5b is shown, the positions of locking recess and locking projection are reversed. Here is a latching recess 21a on the locking hook, namely on the outside of the Arretierrand 10 arranged. A latching projection 22a is provided on the receiving hook and indeed on the recessed groove flank 9b of the receiving groove. 9
  • The embodiment of Fig. 6 shows hook profiles, starting from the FIGS. 3 and 4 In the illustrated locked state of the hook profiles, a free space 23 is formed which extends between the groove bottom 9a of the receiving groove 9 of the receiving hook 6 and a lower side 10a of the arresting edge 10 of the locking hook 7. The free space 23 extends to the outside 10b of the arresting edge 10 or up to the recessed groove flank 9b of the receiving groove 9 zoom. The clearance 23 may receive dirt particles or other loose particles. In the case of wood-based panels, for example, particles can detach from the edge of the panel. Detached should not get between the joining surfaces of the hook profiles and settle there, otherwise they hinder a correct position locking the hook profiles. Between the bottom 10 a of the Arretierrands 10 and the groove bottom 9 a of the receiving groove 9 is the in Fig. 6 proposed space 23 formed gap-shaped. The gap-shaped clearance 23 continues towards the bottom of the groove 9a and in this way creates the desired space for receiving unwanted particles.
  • The embodiment of Fig. 7 shows hook profiles, which also starting from the FIGS. 3 and 4 have a change in such a way that again in the locked state of the hook profiles a clearance 24 is formed, which extends between the groove bottom 9a of the receiving groove 9 of the receiving hook 6 and a bottom 10a of the Arretierrands 10 of the locking hook 7. The free space 24 extends as far as the lower locking surface 12 of the receiving hook 6 or up to the upper locking surface 13 of the locking hook 7 zoom. To create the clearance 24 is the underside 10a of the locking edge 10 is provided with a flat shoulder 24a, which protrudes from the bottom 10a of the locking edge 10. The space 24 can also absorb dirt particles or other loose particles and record in panels of wood materials any detached wood particles that would otherwise set between the joining surfaces of the hook profiles and would hinder a positionally correct locking the hook profiles. The remaining portion of the bottom 10a is in the locked state with the groove bottom 9a of the receiving groove 9 in contact and thereby supported.
  • The embodiment of Fig. 8 also shows hook profiles, by the FIGS. 3 and 4 out. Compared to these figures, only the lower catch 14 has been modified. According to Fig. 8 the locking projection 15 of the receiving hook 6 protrudes further from the outer side 8a of the receiving edge 8 than in FIG Fig. 4 , The depth of the detent recess 16 is opposite Fig. 4 unchanged. This creates a gap 25 between the outside 8a and the set-back groove flank 11a of the locking groove 11 of the locking hook 7. The gap 25 improves the latchability of the lower catch 14th
  • In Fig. 8a the lower catch 14 is enlarged as a section. An alternative to Fig. 8a shows the clipping according to Fig. 8b , Thereafter, the position of locking recess and locking projection is reversed. A detent recess 15a is now arranged on the receiving hook 6 and that on the outer side 8a of the receiving edge 8. A latching projection 16a is provided for this purpose on the locking hook 7 on its recessed groove flank 11a of the locking groove 11.
  • Another embodiment of hook profiles of the panel is in Fig. 9 shown. This too is based on the FIGS. 3 and 4 and also integrates all the changes that are made in the examples of Fig. 5, Fig. 6 . FIGS. 7 and 8 were proposed.
