    [0001] The present invention relates to a panel comprising an upper side, a lower side, a hull, complementary locking means that are provided in pairs on mutually opposite panel edges, having at least one pair of locking means with hook profiles, that is, a receiving hook and, opposite to this, a retaining hook with the measure that the receiving hook is disposed away from the hull, having a hook edge and closer to the hull it has a fitting cutout, being that the fitting cutout is open in the upper direction, the retaining hook having a retaining cutout arranged closer to the hull and open towards the underside, and has a retaining step, disposed away from the hull, which adjusts in the joining direction vertical within the snap-in cutout of the snap hook, with the snap hook having a transverse joining face away from the hull and at the same time, away from the hull, it has a retaining contour. tion of vertical action, with the snap hook, closer to the hull, having a transverse joining face, and also closer to the hull it has a positive union contour, which is suitable in positive union, with the retaining contour of the retaining hook away from the hull, so that panels can be locked, mounted perpendicularly to the plane, and closer to the hull, the retaining hook has a horizontal locking face on its retaining step. the snap hook, away from the hull, has a horizontal locking face within the snap cutout, whereby a snap opening is formed in the snap hook, through which the retaining step can essentially be inserted into the snap cutout towards of joining, whereby the retaining step and the snap opening are so shaped that during a joining movement, the end of the step adjusts without elastic deformation of the legs. hook hooks, initially to such an extent within the mating opening that the horizontal locking face of the retaining hook with a portion of its face receives contact with the horizontal locking face of the mating hook.
    [0002] The document WO2010/015516 A2 proposes a panel in which the hook edge of the receiving hook does not have a flexible thread. Instead, the retaining hook prevents the receiving hook from bending down. The invention is based on the problem of creating a panel whose hook profiles can be easily connected and which nevertheless allow a fixed connection.
    [0003] A2. The underside of the snap hook can be positioned in a plane that is identical to the plane of the underside of the panel.
    [0004] A3. The retaining contour and the positive union contour conveniently form a top hook, the retaining contour having a female or male fitting element, and the positive union contour having a female fitting element, complementary to the contour of retention, or has a male fitting element.
    [0005] A4. In addition, it will be useful for the edge of the receiving hook and the retaining cutout of the retaining hook to form a lower hook, whereby a female engaging element or a male engaging element is provided far from the hull, on the edge of the receiving hook, and the retaining cutout, close to the hull, having a corresponding complementary female engaging element or having a male engaging element.
    [0006] A5. Each female mating element features a mating face that faces toward the top or bottom side of the panel. This means that the mating face's normal plane faces the corresponding direction of the panel. In addition, each male mating element features a mating face that faces toward the other side of the panel. It is foreseen in the case that the mating face of the female mating element, together with the mating face of the male mating element, in the locked state of two panels, reacts to a reciprocal movement away from locked panels, in a perpendicular direction to the the plan of the panel.
    [0007] A6. Preferably, the mating face of the female mating element, in the locked state of two panels, contacts the mating face of the male mating element. In this way, the lower locking contributes to a firm beam perpendicular to panels mounted vertically to the plane.
    [0008] A7. Alternatively, between the mating face of the female mating element and the mating face of the male mating element allocated, in the locked state of two panels, a gap can be provided. This can simplify the assembly process when, for example, a relative displacement has to be made between the transverse edges. A span of a few tenths of a millimeter seems to suffice, with about 0.1 mm being preferred.
    [0009] A8. Advantageously, the panels are shaped in such a way that during the movement of the joint, initially an upper hook and then a lower hook are joined, in the form of a complete joint.
    [00010] A9. The retaining hook and/or the receiving hook may have an area of flexion. Conveniently, this area is shaped in such a way that by its elastic flexibility the width of the locking opening can be increased, so that the retaining step can be fully inserted into the locking cutout and, in addition, the retaining contour of the retaining hook becomes inserts into the contour of the positive union of the receiving hook. Although the retaining contour and the positive union contour are also compressed and deformed, the harder and more fragile the hull material, the smaller the elastic deformation of the retaining contour and the positive union contour and the greater the portion of the elastic deformation of the bending area. With this configuration, it is now possible, even when the hull is formed of a relatively hard and fragile material, to provide a high dimension in terms of recesses for the positive connection between the retaining contour and the positive connection contour.
    [00011] A10. The flexion area, in a simple way, is shaped as a flexible fillet. It can be provided in the area of the hook element protruding from the transverse edge of the panel.
    [00012] A11. The horizontal locking faces of the hook profiles can be slanted to the normal plane of the back face of the panel at an angle of 0° to 45°. The angle of inclination depends essentially on the configuration of the retaining contour and the contour of the positive union, especially depending on the position where the female, i.e. male, interlocking element is disposed. An angle of inclination between 7° and 25° proved to be advantageous. Basically, a smaller inclination can be provided when the retaining contour is provided with the female locking element and the positive joint contour has the corresponding male locking element. The smaller the angle of inclination, the greater the adhesion force against an act of forced reciprocal retraction in the plane of the assembled panels, as well as in a perpendicular direction to the corresponding transverse edges. Preferably, therefore, an angle of inclination of < 7° and, particularly advantageously, an angle of inclination of approximately 3°, are provided. Basically, a negative draft angle of the two horizontal locking faces is also possible. In this way, these would register a locking effect, perpendicular to the plane of the panel. In the case of a replacement of the female and male mating element, a greater inclination angle will normally be convenient, so that the retaining contour can be joined with the contour of the positive union.
    [00013] A12. It will be useful when, away from the hull, the edge of the hook has a sliding oblique plane. In this case, it is a face that is inclined towards the plane of the panel and which simplifies the insertion of the hook edge inside the retaining cutout of the retaining hook.
    [00014] A13. The retaining step, on its side away from the hull, may have a sliding oblique plane. This oblique sliding plane is an inclined face facing the plane of the panel and which simplifies the insertion of the retaining step into the snap-in cutout of the snap hook. The sliding oblique plane is conveniently shaped in such a way that it cooperates with the contour of the positive joint. Since the oblique sliding plane contacts the positive union contour, the positive union contour slides along its length. In this way, the receiving hook and the retaining hook can be moved away from each other parallel to the plane of the panel. At the same time, the horizontal locking face of the retaining hook can exert a force that presses against the horizontal locking face of the receiving hook. This force induced on the horizontal locking face of the receiving hook will be transferred to the receiving hook, which in this way can be elastically deformed. In the continued movement of joining, the retaining contour passes the contour of the positive union to such an extent until both have reached a position, in which they adjust to each other in a positive union. In this way, a closed junction can be obtained. The horizontal locking face of the two hook profiles will then preferably be juxtaposed.
    [00015] A14. It would be advantageous to provide a pair of swivel profiles, i.e. a grooved profile with an undercut on a grooved wall, as well as a spring profile with an undercut on one side of the spring.
    [00016] This presents the advantage that the panels can conveniently be assembled in such a way that a new panel can be applied with a rotating profile in the complementary rotating profile of an already assembled panel, being rotated within this plane.
    [00017] In addition, advantageously, the hook profile of the new panel can also be locked simultaneously with the hook profile of a panel on the same panel row. For this purpose, the retaining hook of the new panel will be lowered in a scissor-like motion essentially in a vertical plane and thus inserted into the receiving hook. During the movement similar to a scissor movement, the retaining step initially projects only at one end of the edge of the panel, into the slot opening. In continuation of the joining movement in scissors movement, the retaining step penetrates step by step into the slot opening. When, finally, the panels meet in a plane, the retaining contour and the positive union contour will precisely match each other; the faces of the transverse joints touch and form a closed joint.
    [00018] A15. On the upper side, a decorative layer may be foreseen.A16. It is also possible that a transparent cover layer is provided on the upper side, through which the hull or decorative layer can be seen. The transparent decorative layer serves to protect the underlying layer. It may have means that minimize wear, eg corundum particle, glass particles, etc.
    [00019] A17. On its underside, a counter-projection layer can be provided. This acts as a balance for the layers provided on the top side in order to react to a panel distortion.
    [00020] A18. The case may at least partially consist of a wood-based product, eg HDF, MDF, chipboard, OSB board, etc.
    [00021] A19. When the hull consists at least partially of a synthetic material, this may be a soft and elastic synthetic material such as a thermoplastic polymer, for example polyolefin, polypropylene, polyurethane or polyamide. Soft PVC can also be envisaged as a soft plastic material. In this case, it is a polyvinyl chloride that contains plasticizers. Basically, however, PVC is an amorphous elastomer that has a natural hardness and brittleness that can only be reduced by plasticizers. It can also be a plastic of natural hardness and brittleness, for example, an amorphous elastomer such as PVC that does not contain, or only a small amount, of plasticizer.
    [00022] In addition, a panel is proposed that comprises a hull with at least one layer of plastic, complementary locking means that are provided in pairs on edges of mutually opposite panels, at least one pair of locking means with hook profiles, that is, a receiving hook and opposite to this a retaining hook as the receiving hook, disposed away from the hull, presents a hook edge and, closer to the hull, presents a fitting cutout, with the cutout of the fitting is open towards the upper side, the retaining hook having a retaining cutout, closer to the hull and open towards the underside, and has a retaining step, disposed away from the hull, which adjusts in a vertical adjustment direction , inside the snap-in cutout of the snap hook, with the retaining hook having a joint face away from the hull and, at the same time, it has a retaining contour, with vertical action, away from the hull, s whereas the receiving hook closest to the hull has a joining face and also closer to the hull, it has a positive union contour, which fits, in positive union, with the retaining contour away from the retaining hook's hull, in order that a vertical locking can be produced, with the retaining hook arranged closer to the hull, presenting a horizontal locking face on its retaining step, and the receiving hook, disposed away from the hull, has a horizontal locking face, inside the snap-in cutout, whereby in the snap-in hook a narrowed snap-in opening is formed, through which the retaining step can essentially be inserted towards the vertical joint, within the snap-in cutout, with the end of the step free of the The retaining step is formed narrower than the width of the engaging opening of the engaging hook whereby the retaining contour of the retaining hook away from the hull is set back in relation to the plane of the joining face of the retaining hook, the contour of the positive union closest to the hull, relative to the receiving hook, at least partially protruding beyond the plane of the joining face of the receiving hook, with the The retaining step and the locking opening are so shaped that the end of the step, during a joining movement without elastic deformation of the hook profiles, initially fits to such an extent within the locking opening that the locking face is horizontal of the retaining hook, with a part of its surface, receives contact with the horizontal locking face of the receiving hook, and the receiving hook has a flexible thread, so shaped that, due to its elastic flexibility, the width of the opening can be increased so that the retaining step can be fully inserted into the recess cutout and, in addition, the retaining contour of the retaining hook inserts into the body. around the positive union of the receiving hook.
    [00023] A20. Method for simultaneous locking of a new square panel, with two longitudinal edges and two transverse edges, in a previous row of panels already assembled, consisting of identical panels, as well as in an identical panel of the same row of panels and already assembled, with the measure that a first longitudinal edge, by rotating the new panel within the plane of the assembled panels, will be joined in positive union with the row of previous panels, while simultaneously a first transverse edge of a new panel, through a movement similar to scissors, will be brought into positive joining contact with a second transverse edge of the assembled panel, of the same row of panels, with the other measure that the first transverse edge of the panels has a first transverse joining face, and the second transverse edge of the panels have a second transverse seam face, the first transverse seam face at that end turns in the direction of the first longitudinal edge, is brought into contact with the second face of the transverse joint of the assembled panel of the same row of panel, and the positive union connection of the longitudinal edge and the transverse edge of the new panel is made by being formed between the new panel and the row of the preceding panels a longitudinal joint slot as well as a transverse joint slot, the quantum end of the transverse joint slot pointing in the direction of the row of previous panels and the conical tip of the joint slot longitudinal points in the direction of the second free transverse edge of the new panel, and the new panel will finally be rotated within the plane of the assembled panels, with the actuation with positive union of the transverse edges and the longitudinal edges, fully joined, and the wedge joint cracks will be removed. Due to the slit of the transverse joint, the transverse edges are slightly offset out of phase in their longitudinal direction. The offset corresponds to the measurement of the gap at the point farthest from the gap in the transverse joint. To eliminate this lag, the transverse edges must be able to be moved by offset against each other. It will then be advantageous for at least one socket, for example the lower socket, to be shaped in such a way that a small gap is provided between the socket faces, for example 0.1 mm, in order to facilitate the mobility of the edges. transversals.
    [00024] A21. The slit of the longitudinal joint can be produced by being the new panel temporarily displaced from its parallel alignment to the row of preceding panels, the wedge-shaped tip of the slit of the longitudinal joint being produced at the far end of the first longitudinal edge of the new panel.
    [00025] A22. The longitudinal joint slit can, on the other hand, be produced in that the new panel is temporarily transformed from its flat shape, being arched from its panel plane towards its upper side.
    [00026] Next, the invention is presented by way of example in a drawing, being described in detail based on several examples of execution. The figures show:

    [00032] Figures 6a-6c schematic presentations of a locking method for assembling panels according to the invention.
    [00033] Figure 1 shows a first pair of edges of a panel 1, that is, 1', according to the invention, that is, a pair of longitudinal edges. A pair of longitudinal edges feature complementary S-slewing profiles. In this sense, all the positive joint profiles known in the state of the art can be foreseen, which through an oblique application of a new panel in a row of previous panels and with subsequent rotation, a new panel 1' can be joined in the plane with positive joint , of the panels already assembled.
    [00034] The complementary swivel profiles S according to figure 1 comprise a grooved profile 2 and a spring profile 3. The grooved profile 2 has an upper grooved wall 2a which is shorter than the lower grooved wall 2b. The lower groove wall, moreover, has a recessed cutout 2c for the spring profile 3. The cutout 2c also has a horizontal locking face 2d. The molar profile 3 has an upper molar face 3a and a lower molar face 3b which essentially run parallel to the upper side 4 of the new panel 1'. The lower side of the spring has a recess 3c and a horizontal locking face 3d which cooperates with the horizontal locking face 2d of the lower groove wall 2b. The oblique positioning of the new 1' panel is shown in Figure 1 by the dashed position of the 3' molar profile. The underside of the spring will be positioned on a more elongated lower grooved wall 2b. The new panel 1' will be inserted with the molar tip in front, into the grooved profile 2 and the new panel 1' will then be rotated to the plane of one or more assembled panels.
    [00035] Figures 2a to 2c respectively present in the cutout a second pair of edges, that is, transverse edges of a panel 1, that is, 1'. Panels 1 and 1' are identical. Each separate panel has on opposite transverse edges a pair of 5 profiles, ie 6 complementary. In panel 1, therefore, the edge not shown identically presents profile 5 of panel 1' and in panel 1' the edge not shown is identical to profile 6 of panel 1.
    [00036] It is also possible modalities of square panels, whose first pair of edges (pair of longitudinal edges) is formed with complementary profiles that are identical to the profiles of the second pair of edges (pair of transverse edges). Next, other examples for pairs of transverse edges are described.
    [00037] The series of figures 2a to 2c presents, in several steps, the main sequencing of the joint movement with the purpose of joining and locking the panels 1 and 1'.
    [00038] The complementary profiles 5 and 6 of each panel 1, i.e. 1', form complementary locking means in the form of hook profiles H. The hook profile of panel 1 forms a receiving hook 7 and the hook profile of the profile 1' forms a retaining hook 8 which fits inside the receiving hook, the two hook profiles being so shaped that a retaining takes place which reacts to a reversal of the joint movement.
    [00039] The panels 1 and 1' can thus, after the locking made, can no longer be separated again perpendicularly to the plane of already assembled panels.
    [00040] Each panel 1 and 1' comprises a hull 9 and 9', on which the aforementioned complementary locking means are arranged. The upper side 4 of the panel forms a usable surface.
    [00041] A hook edge 10 is provided on the receiving hook 7, distant from the hull, and closer to the hull, a receiving cutout 11. The receiving cutout 11 is open towards the upper side 4.
    [00042] The retainer hook 8 has a retainer cutout 13, arranged closer to the hull and open towards the underside 12' and has a retainer step 14 away from the hull. T in the receiving cutout 11 of the receiving hook 7. In addition, the retaining hook 8 has a transverse joining face 15 distant from the hull and also distant from the hull and has a retainer contour 16, of vertical locking action. The receiving hook 7 has a transverse joint surface 17 close to the hull and also close to the hull it has a positive-joining contour 18 which fits in positive-joining with the retaining contour 16 of the retaining hook 8. In this way, a socket V1 is formed. with which a locking can be produced perpendicularly to the plane of the panel.
    [00043] In addition, the retaining hook 8, close to the hull, has a horizontal locking face 19 that is arranged on its retaining step 14. In a juxtaposed sense, the receiving hook 7, distant from the hull, arranged in the receiving cutout 11, has a horizontal locking face 20 which cooperates with the horizontal locking face 19 of the retaining hook 8.
    [00044] The receiving hook 7, in its receiving cutout 11, has a narrowed receiving opening 21. The retaining rung 14 can essentially be inserted in a perpendicular joining direction T within the socket cutout 11, i.e. in a plane perpendicular to the plane of the interlocking panels.
    [00045] According to figures 2a through 2c, the panel 1 with the catch hook 7 is positioned on a firm base (not shown). The retaining rung 14 of panel 1' will be lowered perpendicularly to the plane of the panel (vertical). The retaining contour 16 of the retaining hook 8, remote from the hull, has a female engaging element 16a (concavity). The female locking element 16a has a locking face 16b which is directed towards the upper side 4' of the panel 1' and which is set back with respect to the plane of the face of the transverse joint 15 of the retaining hook 8. The positive joint contour 18, close to the hull of the receiving hook 7, is shaped in such a way that it has a male locking element 18a which has a locking face 18b which is directed towards the underside 12 of the panel 1 and which protrudes beyond the plane of the transverse joint 17 of the receiving hook 7 and which, in locked state, is positioned behind the female engaging element 16a of the retaining hook 8. Furthermore, the retaining rung 14 and the snap opening 21, the free end of the rung being retainer 14, during the beginning of the joining movement, fits into the receiving opening 21, initially without significant elastic deformation of the hook profiles. In this case, the horizontal locking face 19 of the retaining hook 8, with a part of its surface, makes contact with the horizontal locking face 20 of the receiving hook 7.
    [00046] In the receiving hook 7 there is formed a flexible thread 22 which can be better recognized in figure 2b. The flexible thread 22 is shaped in such a way that, by its elastic flexibility, the width of the engaging opening 21 can be widened, so that the retaining step 14 can be inserted without problems into the receiving cutout 11. Furthermore, by virtue of the flexibility of the flexible thread 22, the retaining contour 16 of the retaining hook 8 can be inserted very simply around the contour of the positive union 18 of the receiving hook 7.
    [00047] The hook profiles, at the beginning of the joint path, must be put into cooperation without being already elastically deformed at the cooperation point. Only with continued movement of the joint, the recessed areas, namely the female engaging element 16a of the retaining contour and the male engaging element 18a of the positive joint contour, come into contact at the cooperating point. This contact, however, produces an elastic deformation that essentially takes place at another point, that is, in the flexible thread 22 provided for that purpose. Although the retainer contour 16 and the positive union contour 18 are also pressed and deformed, it happens that the harder and more fragile the hull material 9/9', the smaller the elastic deformation of the retainer contour 16 and the union contour positive 18 and the greater will be the portion of elastic deformation of the flexible thread 22.
    [00048] The female engaging element 16a of the retaining hook 8 can be formed deeper and the male engaging element 18a of the receiving hook 7 may protrude more from the face of the transverse joint 17 of the receiving hook 7 than in the case of a panel no flexible fillet 22. The greater extension in the undercut movement improves the resistance against a reciprocal pulled away of assembled panels, perpendicular to the plane of the panel. Despite the better strength, the retaining contours 16 and the positive joint contour 18 can be brought into contact without problems, because the flexible thread 22 makes it possible to widen the engagement opening 21. The retaining contour 16 and the positive joint contour 28 can thus be moved along one another without intense specific deformation, until it is in positive union cooperation, developing its locking effect.
    [00049] Figure 2b shows that an oblique face, away from the hull, is foreseen on the retaining step 14, which forms an oblique sliding plane 14a. This sliding oblique plane touches the male fitting element 18a of the contour of the positive union 18 of the receiving hook 7. During the scissor-like joining movement of the retaining hook 8, the horizontal movement moving the panels 1/1' will thus be superimposed. in the retraction direction, so that between the transversal joint faces 15/17 a distance is formed. At the same time, the horizontal locking face 19 of the retaining hook 8 exerts a force which presses against the horizontal locking face 20 of the receiving hook 7. The force acting on the horizontal locking face 20 of the receiving hook will be transferred to the thread flexible 22 of the receiving hook which in this way will be elastically curved.
    [00050] Furthermore, figure 2b shows that the snap hook 7, on its hook edge 10, has a male snap element 10a and the retaining cutout 13 has a female snap element 13a that cooperates with the snap element. male fitting 19a and in the assembled state of the panels, they also react to a reciprocal movement away from panels mounted perpendicularly to the planes of panels. With this conformation, a lower V2 hook is formed that reinforces the upper V1 hook. The female locking element 13a has, for this purpose, a locking face 13b which faces towards the upper side 4' of the panel 1', whereas the male locking element 10a has a locking face 10b, facing towards the lower side 12 of the panel 1 and cooperating with the female mating face 13b.
    [00051] The retaining hook 8 is shaped in such a way that in the process of joining, the retaining cutout 13 of the retaining hook 8 will be widened and, in this way, the insertion of the edge of the hook 10 with the male fitting 10a inside will be facilitated of the retainer cutout, which has the female insert 13a. For this purpose, a flexible thread 23 is provided on the retaining hook. When a force acts on the horizontal locking face 19 of the retaining hook 8 from the outside, as shown in Figure 2b by the horizontal locking face 20 of the receiving hook 7, then with this force a flexion of the flexible thread 23 will be produced, which results in the enlargement of the retaining cutout 13 and which facilitates the assembly.
    [00052] In the continuation of the joint movement, the farthest point of the retaining step 14 passes through the slot opening 21 enlarged of the slot cutout 11. It then decreases the curvature of the flexible thread 22 and the slot opening 21 narrows again . The faces of transverse joints 15/17, at a distance k, relative to the panels, will be pressed against each other by the flexural tension of the flexible thread 22. At the same time, it decreases the curvature of the flexible thread 23 and also the edge of the hook 10 reaches in positive union the retaining cutout 13 and the panels are also pressed together by the bending tension of the flexible thread 23. The panels can be pressed together in such a way that a closed transverse joint results.
    [00053] In figure 2c, the retaining contour 16 and the positive union contour 18 have reached a position in which they adjust reciprocally in positive union. The hook profiles H can be shaped in such a way that a remaining part of the bending tension of the flexible thread 22 and 23 remains preserved and on the horizontal locking face 20 of the receiving hook 7 an elastic force (molar force) is exerted to protect permanently face the transverse joint 15 of the retaining hook 8, towards the face of the transverse joint 17 of the receiving hook 7. In this way a permanently closed transverse joint can be obtained. In figure 2, the horizontal locking faces 19, 20 of the two hook profiles H are juxtaposed and do not exert a permanent prestressing.
    [00054] The upper hook V1 and the lower hook V2 are reciprocally synchronized in such a way that first the upper hook reaches its positive-joined position and then the lower hook reaches its positive-join position. To this end, the bending properties (resistance to bending) of the receiving hook 7 and the retaining hook 8 can correspondingly be mutually synchronized.
    [00055] Especially, the conformation of the bending stiffness of the receiving hook 7 requires special precision. When the receiving hook, for example, is bent to a footstep sound dampening base, which on the occasion of a pressure force transferred by the upper side 4 of the panel, offers almost no opposition, the elastic curvature of the flexible thread 22 will have and generate a return force sufficient to ensure the positive union of the lower V2 hook.
    [00056] Figures 3a-3c present a first alternative in relation to the example of execution according to figures 2a-2c. For identical technical characteristics, several reference signs are indicated. The difference consists of a modified conformation of the upper V1 hook. The retaining contour 16 of the retaining hook has a male engaging element 16c. This element features a 16d mating face that now faces towards the 4' top side of panel 1'. On the contour of the positive joint 18 of the receiving hook 7 is a female locking element 18c suitable for the lower hook, having a locking face 18d which is now directed towards the underside 12 of the panel 1. At the beginning of the joining movement, the face of the transverse joint 15 of the retaining hook has a greater distance from the face of the transverse joint 17 than in the example of embodiment of figures 2a-2c. As it now points from the male fitting element 16c collides with the face of the transverse joint 17, the retainer step 14 has altogether a greater distance from this face of the transverse joint 17. So that the retainer segment 14 still fits within the cutout of the socket 11 so that the horizontal locking faces 19 and 20 can respectively be brought into contact, the horizontal locking face 20 is inclined more steeply than in the example embodiment of figures 2a-2c. The inclinations of the faces of the horizontal 19/20 lock are reciprocally synchronized.
    [00057] Figures 4a-4c show an example of execution in which the upper hook V1 is identical in shape as in figures 3a-3c. The upper hook V1 has the same function as described in the preceding execution example, so that reference is made to the description therein. In the region of the lower V2 hook, a modified conformation is foreseen. The edge of the hook 10 of the receiving hook 7 has a female locking element 10c which has a locking face 10d. This engaging face 10d, in this case, faces towards the underside 12 of the panel 1. The cut-out of the retainer 13 of the retaining hook 8 has, in a suitable reciprocal form, a male engaging element 13c. This has a 13d mating face that faces towards the 4' top side of the 1' panel.
    [00058] Figures 5a-5c shows an example of execution, whose upper fitting V1 has a retaining contour that corresponds to figures 2a-2c, but where the horizontal locking face 19 has a greater inclination angle. Bottom fitting V2 is identical to those in figures 4a-4c. In order to be able to join this conformation of the lower hook V2 in a simpler way, the greater inclination angle of the horizontal locking face 19 will be useful. The tilt angle of the horizontal locking face 20 is suitable for the tilt angle of the horizontal locking face 19.
    [00059] For the assembly of a new panel of 24, a process will be used, which, for the locking of a new square panel, has two longitudinal edges and two transverse edges, in a row of P2 panels, already assembled with panels identical, as well as simultaneously for the locking in a panel 25 of the same row of P3 panels, already assembled.
    [00060] Figure 6a shows the production of an assembled face of panels according to the invention. The rows of panels P1-P3 are presented by cutouts. The new quadrangular panel 24 is only shown schematically. In the different panels used, this is an example of execution with a pair of longitudinal edges 24a/24b that have positive-joining and complementary S swivel profiles, and a pair of transverse edges 24c/24d that have complementary H hook profiles . S slewing profiles are used to interconnect panels from different rows of panels. In this example of execution, the hook profiles H serve to interconnect panels of the same row of panels P3. The hook profiles H of the pair of transverse edges can be shaped in such a way as in one of the examples of execution, according to figures 2a to 5c.
    [00061] Figure 6a shows how on the more advanced row of panels P3 a new panel 24 is mounted, which must be locked both with the previous row of panel P2 as well as with a transverse edge 25d of an adjacent panel 25 of the same row of P3 panels. The new panel 24 is applied obliquely with respect to the planes of the assembled panels and with one of its swivel profiles S on the front row of panels P2. Then, by rotating the plane of the assembled panels, it will be locked with the previous row of panels P2. At the same time, the hook profile (retaining hook 8) provided on the transverse edge 24c of the new panel 24 will also be locked, hooks with the hook profile (receiving hook 7) provided on the transverse edge 25d, this profile of the panel 25, of the same row of P3 panels. While the new panel 24 is being rotated to the plane of the assembled panels, the retaining hook 8 will likewise be moved in a scissor-like joining motion, in cooperation with the receiving hook 7.
    [00062] The positive union of the longitudinal edge 24a and the transverse edge 24c of the new panel 24, in this case, is produced, whereby between the new panel 24 and the preceding row of panels P2, a longitudinal joint gap L is produced, as well. as a transverse joint slit Q, between the transverse edge 25d of the panel 25 and the transverse edge 24c of the new panel 24. The conical tip of the transverse junction slit Q points towards the row of preceding panels P2 and the wedge-shaped edge of the segment of the longitudinal joint L points towards the second free transverse edge 24d of the new panel 24. When the new panel 24 is finally rotated into the plane of the assembled panels, the positive joining cooperation of the transverse edges 24c/25d and the longitudinal edge 24, it will be fully joined with the row of preceding panels P2, as well as the wedge-shaped joint gap Q and L will be eliminated.
    [00063] The slit of the longitudinal joint L will be produced, with the new panel 24 being temporarily moved away from its parallel alignment with the previous row of panels P2 and the tip of the wedge of the slit of the longitudinal joint L will be produced at the far end of the first longitudinal edge 24a of new panel 24.Reference Listing1 Panel1' Panel2 Grooved Profile 2a Upper Grooved Wall 2b Lower Grooved Wall 2c Cutout 2d Horizontal Locking Face 3 Molar Profile 3a Upper Spring Side 3b Lower Spring Side 3c Recess 3d Horizontal Locking Faces 4 Top side 4' Top side 5 Profile 6 Profile 7 Receiving hooks 8 Retaining hooks 9 Hull 9' Hull 10 Hook edge 10a Male fitting 10b Fitting face 10c Fitting female element 11 Fitting cutout 12 Bottom side 12' Side bottom 13 Retaining cutout 13a Female mating element 13b Mating face 14 Retaining rung 14a Sliding oblique plane 15 Joint face transverse (retaining hook) 16 Retaining contour 16a Female mating element 16b Mating face 16c Male mating element 16d Mating face 17 Transverse mating face (receiving hook) 18 Positive mating contour 18a Male mating element 18b Mating face 18c Female mating element 18d Mating face 19 Horizontal locking face (retaining hook) 20 Horizontal locking face (receiving hook) 21 Mating opening 22 Flexible fillet (receiving hook) 23 Flexible fillet (retaining hook) 24 New panel 24a Edge longitudinal 24b Longitudinal edge 24c Transverse edge 24d Transverse edge 25c Panel 25d Transverse edge H Hook profile L Longitudinal joint slot Q Transverse joint slot S Swivel profile T Joint direction V1 Top hook V2 Bottom hook.
