    [001] The present invention relates to a panel, in particular a floor panel, comprising a body with at least one plastic layer, complementary locking means provided in pairs on mutually opposite panel edges so that a plurality of said panels can be locked, at least a pair of locking means with hook profiles, that is, a reception hook and in relation to this opposite a retaining hook, with the proviso that the reception hook has a hook edge away from the body and a receiving recess arranged closer to the body, where the receiving recess is opened towards the upper side, the retaining hook is provided with a retaining recess arranged closer to the body and opened on the lower side and it has a retention step that is located away from the body and that fits in a vertical joining direction within the reception recess of the reception hook, the retaining hook has a d surface and union away from the body and also a vertical actuating retaining contour away from the body one, the receiving hook has a joining surface closer to the body and also a positive locking contour closer to the body that adjusts in relation to locking positive with the retaining contour, which is distant from the retaining hook body so that vertical locking can be implemented, the retaining hook has a horizontal locking surface close to the body in its retaining step, the receiving hook has a horizontal locking surface disposed away from the body in the receiving recess, a narrowed receiving opening is formed in the receiving hook and through this the retaining step can be inserted substantially in the direction of vertical joining in the receiving recess.
    [002] A general type panel presented, for floors, is known from WO 2010/015516. The hook profiles of the known panels are adapted to the material from which the panel body is formed. Panels having a body comprising a flexibly soft and elastic plastic material can be hooked. The retaining contour provided below the joining surface of the retaining hook has regions that protrude from the plane of the joining surface and other regions that are recessed in relation to the plane of the joining surface. Likewise, the positive locking contour provided below the joining surface of the receiving hook has regions that protrude from the plane of the joining surface and other regions that are recessed in relation to the plane of the joining surface. The regions mentioned above that protrude and recede in the positive locking contour and the retaining contour form lower cut configurations that prevent the movement of the two hook profiles distant from each other in a direction perpendicular to the plane of the panel (vertically). To be able to combine the lower cut configurations, the retaining contour and the positive locking contour are pressed against each other and next to each other. In that case, they must be elastically deformed. The retaining contour and the positive locking contour are smoothly elastic and can therefore be placed in positive locking contact. The maximum amount of lower cut configuration is limited due to the flexible-elastic property of the plastic material. The vertical locking action is unsatisfactory.
    [003] The objective of the invention is to improve the panel in which the large number of plastic materials that can be used in the body is increased and the vertical locking action is improved as much as possible.
    [004] According to the invention, this objective is achieved, with this the retaining contour, which is far from the body, of the retaining hook is drawn back behind the plane of the retaining hook joining surface, the locking contour positive, which is closer to the body, the receiving hook protrudes at least partially beyond the plane of the joining surface of the receiving hook, the holding step and the receiving opening have such a configuration that the step end during a movement the joint is adjusted initially without the elastic deformation of the hook profile in the reception opening in such a way that the horizontal locking surface of the retaining hook makes contact with part of its surface with the horizontal locking surface of the receiving hook and the receiving hook has a flexural leg adapted so that the width of the receiving opening can be increased by its elastic flexibility and so that the holding step can be It must be completely inserted into the recess and the retaining contour of the retaining hook should also be inserted into the positive locking contour of the receiving hook.
    [005] With these measures it is possible that the portions of the hook profile enter into engagement at the beginning of the joining movement without them being already elastically deformed in the engagement position. It is only by means of an additional advance in relation to the joining movement that the lower cut regions of the retaining contour and the positive locking contour come into contact in the engagement position in such a way that the elastic deformation is caused, the flexural leg being specifically provided for the purposes of elastic deformation. Of course, the retaining contour and the positive locking contour are also pressed and deformed, however, the harder and more fragile the plastic material of the body, correspondingly the lesser the degree of elastic deformation of the retention contour and the contour positive locking and correspondingly greater will be the proportion of elastic deformation of the flexural leg. Due to this design configuration, it is now possible, even when the body is formed of a relatively hard and fragile plastic material, to provide a high degree of lower cut configuration for the positive locking engagement between the retaining contour and the contour of positive locking. The positive locking contour, for example, can have a locking element that protrudes further than in the prior art, and the retaining contour has a locking recess that is complementary to the locking element and that is deeper than in the state of the art. However, the retaining contour and the positive locking contour can be engaged without any problem, as the flexural leg adapted for this purpose flexes elastically and this flexion allows an increase in the reception opening. In this way, the retaining contour and the positive locking contour can be moved close to each other without a strong inherent deformation, until they engage.
    [006] The plastic layer of the body or core may be formed of a flexible and elastic plastic material such as a thermoplastic polymer, for example, polyolefin, polypropylene, polyurethane or polyamide. The so-called malleable PVC can also be considered as a malleable plastic material. This involves polyvinyl chloride which contains plasticizer. Basically, however, PVC is an amorphous elastomer that has a natural hardness and fragility that can be reduced only by the plasticizer.
    [007] Advantageously, however, the panel has such a configuration that it is also possible to produce the plastic core layer from a plastic material with natural hardness and fragility, for example, an amorphous elastomer such as PVC that does not contain any plasticizer or just one small amount of plasticizer.
    [008] Depending on the respective modality of the invention, the thickness of the panels according to the invention is 3 to 10 mm, preferably 4 to 8 mm, particularly preferably 5 to 6 mm. The weight in relation to the surface area of the panel, depending on the respective thickness and specific structure, is between 1 and 2.5 kg / m2, preferably between 1.6 and 1.8 kg / m2.
    [009] A resilient locking tab can be provided on the hook edge of the receiving hook away from the body, where the retaining recess next to the body has a locking recess that fits with the resilient locking tab. This provides a second position within the hook connection, which will be joined by elastic deformation of a region that is provided and adapted for this purpose, that is, the resilient locking tongue. The resilient locking tongue, together with the retaining recess, also implements the locking of the two hook profile portions in a vertical direction, that is, perpendicular to the plane of the locked panels.
    [0010] The elastic properties of the body can be used if the resilient locking tongue is formed integrally with the body. If the body is formed from a relatively hard plastic material, it promotes inter alia the production of the resilient locking tongue by cutting production processes such as milling.
    [0011] The resilient locking tab is attached to the far side of the hook edge body and the free end of the resilient locking tongue projects at an angle from the hook edge, for example, tilted downwards. The resilient locking tongue is always arranged so that contact with the complementary hook profile portion causes the spring movement into the integral locking tongue, which moves it closer to the body of your panel.
    [0012] Desirably, the resilient locking tongue has a sliding surface, away from the body. This surface comes into contact with the retaining hook during a vertical joining movement. This movement causes the resilient locking tab to be moved closer to the hook edge of the receiving hook. In this way, it is elastically tensioned and allows the joint movement. The retaining hook can then be pushed further into the receiving hook until each panel is on a plane.
    [0013] A free space where the locking tab can be flexibly engaged can be provided between the resilient locking tab and the hook edge. The elastic pre-stress makes it possible for the resilient locking tongue to return in the direction of its neutral position if there is space for it.
    [0014] Desirably, the locking recess has a locking contact surface. Through contact with the resilient locking tab, retention of panels connected in a vertical direction is provided.
    [0015] Preferably, the locking contact surface has such a configuration that it forms an inclined support surface for the free end of the resilient locking tab. The inclined support surface has such a configuration that the tensioned locking tab, when returned in the direction of its neutral position, leans against the inclined support surface. This can also be arranged so that the locking tab rests against the support surface before it reaches its neutral position so that a residual part of the tension is always maintained on the locking tab, and that it serves to provide an action of secure retention.
    [0016] It is considered as an additional advantage if the retention step, on its side away from the body, has a sliding inclination that will be referred to as an inclined sliding surface. The inclined sliding surface has such a configuration that it cooperates with that region of the positive locking contour, which is projected. This region of the positive locking contour, projecting from the joining plane, forms, for example, a projection locking element. The projection region cooperates with the sloping sliding surface of the holding step. As soon as the slanted sliding surface comes into contact with the projection region, for example, the locking element, it slides along the locking element. In this way, firstly, the joining surfaces of the receiving hook and the holding hook are moved apart from each other. At the same time, the horizontal locking surface of the retaining hook exerts a force that presses against the horizontal locking surface of the receiving hook. The force that is applied to the horizontal locking surface of the receiving hook is transmitted to the flexural leg of the receiving hook, which is then elastically flexed. In the additional joining movement, the retaining contour passes the positive locking contour to the point that both reach a position in which they adjust in relation to positive locking. In this case, by means of the horizontal locking surface of the receiving hook, the flexural tension in the flexural leg exerts a force that pre-presses the joining surface of the retaining hook in the direction of the joining surface of the receiving hook. In this way, it is possible to make a closed joint. The horizontal locking surfaces of the two hook profile portions are then preferably in a condition to be intimately abutted.
    [0017] The degree of flexion of the flexural leg can be influenced by the geometric shape of the sloping sliding surface (linear or curved). The flexural tension produced can be adapted by a variation in the slanted sliding surface that the plastic material is not overloaded in the flexural leg region and does not suffer any damage.
    [0018] A pair of complementary locking means is in the form of pivoting profile portions. More specifically, a groove profile portion with a lower cut configuration of a groove wall and a tongue profile portion with a lower cut configuration on one side of the tongue portion are provided.
    [0019] This has the advantage that the panels can be desirably placed so that a new panel with a portion of the voting profile pi is adjusted to the portion of the voting profile pi complementary to a panel that is already arranged in the laying plan and is rotated down.
    [0020] Advantageously in this respect, the hook profile portion of the new panel can be simultaneously locked in the hook profile portion of a panel in the same row of panels. For this purpose, the retaining hook of the new panel is moved down substantially in a vertical plane in a scissor-like motion and inserted into the receiving hook. During a scissor-like movement, the holding step first projects only at one end of the panel edge into the receiving opening. When the scissor joint movement continues, the holding step moves step by step into the receiving opening. The elastic deformation of the flexural leg, which is initiated through this, also increases step by step. When the panels are finally laid out in a plane, the retaining contour and the positive locking contour are exactly adjusted, the joining surfaces are in contact and form a closed joint. In addition, the flexural tension in the flexural leg is eliminated again and the horizontal locking surfaces of the two portions of the hook profile touch comfortably in contact with the surface.
    [0021] The use area can be increased if a decorative layer is provided on the top side of the panel. An additional benefit is provided by the provision of a transparent covering layer through which the decorative layer is visible. The transparent cover layer serves to protect the decorative layer. This can be supplied with wear reducing media, for example, corundum particles, glass particles and so on. In that regard, it may be desired that a reinforcement layer is provided on the underside of the panel. This acts as a balance for the layers provided on the top side, to prevent distortion of the panel.
    [0022] The invention is illustrated by way of example in a drawing and described in detail by way of reference to numerous Figures, in which:
    [0023] Figs. 1a-1d show complementary locking means of a first pair of edges of a panel according to the invention and a gradual joining movement to lock two panels,
    [0024] Figs. 2a-2d show an alternative embodiment of a first pair of edges of complementary locking means of a panel and the gradual joining movement to lock two panels,
    [0025] Fig. 3 shows a floor covering comprising the panels according to the invention, which has a second pair of edges with complementary locking means in the form of portions of pivoting profile portions, and
    [0026] Fig. 4 shows an embodiment of a pair of edges comprising the pivoting profile portions.
    [0027] Figs. 1a to 1d show a portion of two panels 1 and 2 respectively. Panels 1 and 2 are identical. Each individual panel has complementary profile portions 3 and 4 respectively at mutually opposite panel edges of a pair of edges. In the case of panel 1, therefore, the edge that is not identically shown has the profile portion 4 of panel 2 while in the case of panel 2, the edge that is not identically shown has the profile portion 3 of panel 1.
    [0028] In the case of a panel that has four edges, the second pair of edges can be formed with complementary profile portions that are identical to those of the first pair of edges.
    [0029] The series in Figs. 1a to 1d illustrates in a plurality of steps the implementation in principle of the joining movement for the purposes of connecting and locking panels 1 and 2.
    [0030] The complementary profile portions 3 and 4 of each panel 1 and 2 respectively form complementary locking means V in the form of hook profile portions H. the hook profile portion of the profile portion 1 forms a hook of the receiving profile 5 and the hook profile portion of the profile portion 2 forms a retaining hook 6 that fits on the receiving hook 5, in which the two hook profile portions have such a configuration that a retention action is produced. The retention action prevents the reversal of the joining movement. Panels 1 and 2 after locking were affected, so they cannot be released in a later movement.
    [0031] Each panel 1 and 2 respectively includes a body 1 'and 2' respectively with a plastic layer where the complementary locking means V mentioned above are arranged. An upper side 7 of the panel forms a work surface. A hook edge 8 is provided distant from the body on the receiving hook 5 and a receiving recess 9 is provided closest to the body. The reception recess 9 is opened on the upper side 7.
    [0032] The retaining hook 6 is provided with a retaining recess 11 which is arranged closer to the body and which is opened on the lower side 10, and has a retaining step 12 in a position distant from the body. The retaining step 12 fits in a vertical joining direction T within the receiving recess 9 of the receiving hook 5. In addition, the retaining hook 6 has a joining surface 13 distant from the body and also a retaining contour 14 distant of the body that has a vertical locking action. The receiving hook 5 has a joining surface close to the body and also a positive locking contour 16 close to the body that fits in a positive locking relationship with the retaining contour 14 of the retaining hook 6. In this way, it is possible to implement vertical locking.
    [0033] In addition, the retaining hook 6 has a horizontal locking surface 17 arranged close to the body that is arranged in its retaining step 12. In combination, the receiving hook 5, disposed in the receiving recess 9 away from the body, has a horizontal locking surface 18 that cooperates with the horizontal locking surface 17 of the retaining hook 6.
    [0034] The receiving hook 5 is provided with a narrowed receiving opening 19 in its receiving recess 9. The retaining step 12 can be introduced in the receiving recess 9 substantially in a vertical joining direction T, that is, in a plane perpendicular to the plane of the locked panels.
    [0035] With reference to Figs. 1a to 1d, the panel 1 is arranged with the receiving hook 5 on a fixed substrate (not shown). The retention step 12 of the panel 2 is lowered perpendicularly to the plane of the panel (vertically). The retaining contour 14, which is located away from the body, of the retaining hook 5 has a locking recess 14a which is recessed behind the plane of the joining surface 13 of the retaining hook 6. The positive locking contour 16, which is close to the body, of the receiving hook 5 has such a configuration that it has a locking element 16a that protrudes beyond the plane of the joining surface 15 of the receiving hook 5 and in the locked condition it engages in / behind the locking recess 14a of the retaining hook 6. Furthermore, the retaining step 12 and the receiving opening 19 have such a configuration that the free end of the retaining step 12, during the beginning of the joining movement, first fits into the receiving opening 19 without any -significant elastic formation of the hook profile portions. In this case, the horizontal locking surface 17 of the retaining hook 6 contacts a part of its surface with the horizontal locking surface 18 of the receiving hook 5.
    [0036] A particular flexural leg 20 is provided on the receiving hook 5, which can be better seen from Figs. 1b and 1c. The flexural leg 20 has such a configuration that the width of the receiving opening 19 can be increased by the elastic flexibility of the leg so that the retaining step 12 can be inserted into the receiving recess 9 without any problem. Furthermore, due to the flexibility of the flexural leg 20, the retaining contour 14 of the retaining hook 6 can be more easily introduced into the positive locking contour 16 of the receiving hook 5.
    [0037] At the beginning of the joining movement, the hook profile portions are placed in engagement without them being already elastically deformed in the engagement position. Only with further progress with the joining movement do the lower cut regions of the retaining contour 14 and the positive locking contour 16 come into contact in the engaged position. However, this contact causes elastic deformation that occurs substantially in another location, more specifically in the flexural leg 20 provided for this purpose. Of course, the retaining contour 14 and the positive locking contour 16 are also pressed and deformed, however, the harder and more fragile the plastic material of the body is, the correspondingly lesser the degree of elastic deformation of the retention contour 14 and the positive locking contour 16 and correspondingly greater will be the degree of elastic deformation of the flexural leg 20.
    [0038] The locking recess 14a of the retaining hook 6 is deeper than in the prior art. Likewise, the locking element 16a of the receiving hook 5 projects beyond the joining surface 15 of the receiving hook 5 than in the state of the art. As a result, there is a greater degree of lower cut configuration in the vertical joining direction than in the prior art. However, the retaining contour 14 and the positive locking contour 16 can be engaged without any problem. This is due to the fact that the flexural leg 20 is elastically flexible so that this flexion allows for the increase of the receiving opening 19. The retaining contour 14 and the positive locking contour 16 can thus be moved close to each other without strong inherent deformation of this, until these engage in positive locking engagement and distribute their vertical locking action.
    [0039] Fig. 1b shows that an inclined surface is provided far from the body in the retention step 12, that surface forms an inclined sliding surface 12a. The slanted sliding surface contacts the projection locking element 16a of the positive locking contour 16 of the receiving hook. As a result, during the vertical joining movement of the retaining hook 16, a horizontal movement is superimposed, this moves the panels apart from each other so that a space is formed between the joining surfaces 13, 15. At the same time, the horizontal locking surface 17 of the retaining hook 6 exerts a force that presses against the horizontal locking surface 18 of the receiving hook 5. The force acting on the horizontal locking surface 18 of the receiving hook 5 is transmitted to the flexural leg 20 of the receiving hook 5, which as a result is elastically flexed.
    [0040] In the additional joining movement as shown in Fig. 1c, the widest location of the retention step 12 passes the increased reception opening 19 of the reception recess 9. Flexion of the flexural leg 20 then decreases and the reception opening 19 narrows again. The joining surfaces 13, 15 of the panels, which are in the k spacing, are pressed against each other by the flexural tension in the flexural leg 20.
    [0041] In Fig. 1 d, the retaining contour 14 and the positive locking contour 16 have reached a position in which they adjust in relation to positive locking. The hook profile portions H can be designed so that a residual flexural tension is maintained on the flexural leg 20 and an elastic force (spring force) is exerted through the horizontal locking surface 18 of the receiving hook 5, that pre -presses the joining surface 13 of the retaining hook 6 permanently in the direction of the joining surface 15 of the receiving hook 5. A closed joint can be permanently made in this way. In Fig. 1d, the horizontal locking surfaces 17, 18 of the two portions of the hook profile H are in a condition of close contact and they do not exert a permanent pre-stress action.
    [0042] Figs. 2a through 2d show a portion of two panels 1 and 2 respectively. These are again identical. Each individual panel has the complementary profile portions illustrated on mutually opposite panel edges of a pair of edges. In the case of a panel with four edges, the second pair of edges is provided with complementary profile portions identical to the panel edges of the first pair of edges.
    [0043] The series of Figures again shows in a plurality of steps 2a to 2d, the implementation of the principle of the joint movement to connect and lock the panels.
    [0044] The mode of panel 1 and 2 respectively as shown in Figs. 2a to 2d corresponds substantially to the embodiment of Figs. 1a to 1d. In this respect, the same references are used for identical characteristics, as in Figs. 1a to 1d. As shown in Figs. 2a to 2d, a second positive locking action is provided. For this purpose, a resilient locking tab is provided which is fixed to the hook edge 8 of the receiving hook 5. The retaining recess 11 has a locking recess 22 next to the body which cooperates with the resilient locking tab 21. In this way, there is a second location within a hook connection, which will be adjusted without any problem by elastic deformation of an adapted region and provided for this purpose, that is, the resilient locking tongue 21. The resilient locking tongue 21 together with the retaining recess 9 it also provides for the locking of the two portions of hook profile H in a vertical direction, that is, perpendicular to the plane of the locked panels.
    [0045] The resilient locking tongue 21 is integral with the body. In this respect, the elastic properties of the body are used. The locking effect of the resilient locking tab 21 is desired if the plastic material of the body is relatively hard and flexibly rigid. A harder plastic material, therefore, performs better than a soft plastic material that deforms easily.
    [0046] The resilient locking tab 21 projects sloping downwardly from the hook edge 8. When panel 1 is located with its bottom side 10 on a substrate (not shown) the free end of the resilient locking tab 21 points towards the substrate. The resilient locking tongue 21 has a sliding surface 23 away from the body that contacts the retaining hook 6 during the joining movement and causes an internal spring movement of the locking tongue 21. Due to this movement, the locking tongue lock 21 is moved closer to the hook edge 8 or closer to the panel body 1. In this case, the resilient locking tab 21 is elastically tensioned and allows the vertical joining movement so that the retaining hook 6 can be additionally demoted. The retaining hook 6 can then be additionally inserted into the receiving hook 5 until the two panels 1 and 2 are arranged in a plane. A free space 24 in which the locking tab 21 can be flexibly flexibly engaged between the resilient locking tab 21 and the hook edge 8. The elastic pre-stress of the locking tab 21 makes it possible for the locking tab to return towards its neutral position if there is room for it. A space is available when the locking tab 21, during the joining movement, passes within the region of the locking recess 22 of the retaining hook 6.
    [0047] The locking recess 22 has a locking contact surface 25 which, upon contact with the resilient locking tongue 21, causes the vertical retention of interconnected panels, that is, perpendicular to the panel plane.
    [0048] The locking contact surface 25 has such a configuration that it forms an inclined support surface for the free end of the resilient locking tongue 21. The inclined support surface 26 has such a configuration that the resilient locking tongue tensioned 21, when returned in the direction of its neutral position, it leans against the inclined support surface 26 before reaching its neutral position. Thus, a residual pre-stress will always be maintained on the locking tab 21, thus ensuring a safe holding action.
    [0049] A preferred embodiment of a quadrangular panel is shown in Fig. 3 which illustrates the production in parts of a panel floor covering according to the invention. The panels used involve a modality with a first pair of edges which has complementary hook profile portions H and a second pair of edges provided with complementary positive locking profile portions S. The profile portions S are used to interconnect the panels different rows of panels. In this embodiment, the hook profile portions H serve to interconnect the panels of the same row of panels. The hook profile portions H of the first pair of edges can be designed as in the embodiment of Figs. 1a to 1d. Alternatively, the H-profile portions of the first pair of edges may correspond to the modality shown in Figures 2a to 2d.
    [0050] Fig. 3 shows in the first row of panels III a new panel 27 that will be locked in the previous row of panels II and also in the adjacent panel 28 of the same row III. The new panel is tilted in relation to the plane of the installed panels and is fixed with its pivoting profile portions S in the front row of panels II. Then, this is locked in the previous row II by a downward pivoting movement in the plane of the seated panels. At the same time, in this case, the hook profile portion (retaining hook 6) of the new panel 27 is also locked in the hook profile portion (receiving hook 5) of panel 28 of the same row III. Although the new panel 27 rotates downward on the plane of the fixed panels, the retaining hook 6 is simultaneously engaged with the receiving hook 5 in a scissor-like motion. The receiving hook 5 has a flexural leg whose elastic flexion is completed step by step, the farther the retaining hook 6 is moved towards the receiving hook 5 or the further away the retaining step 6 retaining hook is. inserted into the receiving recess of the receiving hook 5.
    [0051] The second pair of edges can be implemented with complementary pivoting profile portions S in the form of all known positive locking profile portions that can be positively connected in a lockable manner by tilting a new panel in an anterior row of panels and then rotate the new panel down on the plane of the seated panels. One embodiment of this pivoting profile portion S is shown in Fig. 4.
    [0052] The complementary pivoting profile portions S in Fig. 4 include a groove profile portion 29 and a tongue profile portion 30. The groove profile portion 29 has an upper groove wall 29a that is shorter than the lower groove wall 29b. The lower groove wall 29b is also provided with a lower cutting indentation 29c for the tongue profile portion 30. The indentation 29 also has a horizontal locking surface 29d. The tongue profile portion 30 is provided with an upper tongue side 30a disposed substantially parallel to the upper side 7 of the new panel 27. The lower tongue side 30b has a lower cut configuration 30c and a cooperating horizontal locking surface 30d with the horizontal locking surface 29d of the lower groove wall 29b. The inclined position of the new panel 27 shown in Fig. 3 is clearly indicated in Fig. 4 by the position shown in dashed line of the tongue profile portion 30 '. The bottom side of tongue 30b is placed on the longest bottom groove wall 29d. The new panel 27 is moved with the tip of the tongue driven into the groove profile and the new panel 27 is then rotated downward on the plane of the panel or panels seated.
