Panel, in particular floor panel
The invention relates to a panel, in particular floor panel, with a top and a bottom and means for detachably connecting the panel to adjacent panels by pivoting, wherein as a means at a first longitudinal and / or a first transverse edge of a respective via the respective longitudinal - and / or transverse edge projecting spring having a lower and an upper tongue surface is provided which divides the longitudinal and / or transverse edge into an upper and a lower edge portion, and wherein the first longitudinal and / or the first transverse edge opposite second longitudinal - and / or second transverse edge respectively has a corresponding with the spring of an adjacent, identically formed panel surrounded by an upper side and a lower side panel section groove, preferably the lower side panel section opposite the upper side panel portion is formed above and wherein preferably the lower edge portion against is arranged set back above the upper edge portion.
Such panels are usually made of wood or wood materials, such. B. particle board, HDF board (High Density Fibreboard) or MDF (Mitteldichtefaser- plates). They are suitable for laying laminate or parquet floors or as wall and ceiling panels. Wood materials are usually provided with an upper-side decorative layer. This may be a painted or printed decorative paper, which is laminated onto a substrate. If floors due to the voltage compensation nor a return is applied under each other usually. The panel itself can be formed one layer but also multilayered.
Of course also an embodiment is conceivable in which the lower and upper side panel portion aligned approximately and the lower and the upper edge portion of the other part are aligned roughly. Also, an embodiment in which the lower side panel section opposite the oberseitigem panel section is set back, and the lower edge portion opposite the upper edge portion is formed above, is also conceivable.
When laying the plank to be installed is applied with its edge in the tilted state to the associated edge of an already laid panel and it is pivoted in connection downwards, so that in this way a locking both in a direction perpendicular to the top of the panel and in a direction is implemented perpendicular to the locked side edge of the panel. A disadvantage is that a small gap can remain in the region of the upper sides between the adjacent panels in the pivoted state.
The object of the invention is to avoid the aforementioned disadvantage and to provide a panel in which a gap-free surface is produced in the connected state with another panel. This object is achieved in that the spring has at its upper tongue surface has a projection with a rearward facing in the direction S of the upper edge portion contact surface, and the upper side panel portion on the underside has a protrusion at least partially receiving cavity with a cooperating with the contact surface mating surface, wherein cooperating counter surface in the pivoted state with the contact surface of an adjacent panel so that the panels have the interconnected by swiveling state, a compound which is free from play in the direction of a related to the orientation of the surfaces of the edge portions of the vertical, and wherein the panels upon connection of the panels are pulled by pivoting due to the cooperation of the contact surface and opposite surface against each other, so that the contacting surfaces in the connected state, that is, the upper edge portion and the top panel portion for INDEST abut in the area of upper surface of the panels to each other.
Below rearwardly facing towards the upper edge portion will be understood that the contact surface is not aligned parallel to the top of the panel and the normal (N) on the contact surface from the end of the spring as seen on the panel, in particular at an angle between 0 ° and made 90 °, assigns.
Because of the interaction between the contact surface and the counter surface so the connected panels are drawn together and so ensure that the adjacent panels are in contact without any gap in the region of the upper sides. Here, the lower side panel section is based on the underside of the panel is not deflected downwardly in the locked state. The lower spring surface is designed such that locking by a pivoting-in is possible. For example, the lower spring surface may be formed only in the convex region of the free end of the spring, while the remaining portion of the lower tongue surface, for example, planar, preferably formed parallel to the top. Instead of the convex curvature of the spring in the region of the free end and a chamfer is also conceivable. The lower-side panel section is the upper side adapted to the contour of the lower spring surface.
The means can be formed integrally with the panel. but it is possible also a two-part design. Then the funds can be made of another material such. As plastic, and by an appropriate measure, z. B. gluing, be secured to the respective panel. Also conceivable is that the agents are introduced into a groove in the panel.
The lower-side panel portion may have a pointing in the direction of the top of the panel projecting Nutwandungsbereich which cooperates with a provided on the adjacent panel in the undercut interconnected by pivoting state of the two panels. In this case, two adjacent panels are locked twofold, on the one hand takes place a form fit between the projection and the recess and the other, a form fit between the lower side panel portion and the undercut.
If the Nutwandungsbereich in the pivoted state contacts the undercut of the adjacent panel on the upper side, it further limits the pivoting movement. Alternatively, the lower side panel portion may have a pointing in the direction of the top of the panel projecting Nutwandungsbereich, which is located in the interconnected by pivoting state of the two panels in a recess provided on the adjacent panel undercut without the surfaces of the Nutwandungsbereich with the corresponding surfaces of undercut in contact. In this embodiment is a simple latch that is implemented between the projection and recess, as the Nutwandungsbereich is free in the undercut and thus will be no interaction in the sense of an additional lock.
The projection may be formed in approximately triangular. Here, the protrusion may be formed in isosceles about, so that in this respect the contact surface and the other surface have an equal gradient and an equal length. but it is also quite possible that both surfaces differ from each other in pitch. Preferably the contact surface is steeper than the other, the free end of the spring facing surface.
The protrusion may alternatively have an approximately curved contour. It is conceivable, for example a flattened round or crescent-like design rounding.
but the projection may also have an approximately rectangular contour or a flattened trapezoidal contour. Of course, other embodiments of the projection are possible.
As far as the contour of the recess, it is preferably adapted to the contour of the projection. but this is not essential. It is only essential that the projection at least partially engages in the recess in the locked state. Therefore, it is quite conceivable that, for example, the contour of the protrusion is triangular, while the recess has a semicircular contour.
relevant to the locking is primary, that the contact surface with the mating surface on entering pivoting of the panel to be installed to come into contact, so that as the panels are drawn against each other. The contact area between the contact surface and the mating surface can be line-shaped, but selectively also formed flat.
The upper side panel portion and / or the upper edge portion may (can) at least in a partial region, in particular with formation of a cavity, in the direction of the bottom inwardly extending, in particular set back, may be formed. This prevents that there may be an upper-side gap formation, in use of the installed panels.
The spring may be formed at least partially curved convexly on its lower tongue surface, wherein the lower side panel portion is formed on the top side accordingly. This ensures uniform swiveling is possible. If a Nutwandungsbereich is provided this assists in guiding the swiveling and to be laid panel during the pivoting movement. Of course, the lower spring convex surface may be formed also over its entire length.
The spring may be formed in particular at its lower tongue surface only in the region of its free end convex. In such an embodiment, the convex formation begins at the lowest point and increases towards the free end of the spring.
The convex lower tongue surface can have a uniform curvature. In such an embodiment the radius along the curve profile is uniform.
Of course, also another embodiment is possible such that the circular path of the convexly shaped lower tongue surface has different radii. These different radii may have one and the same center or else separate center points.
The lower spring surface of the spring may be in the lowest point, that is approximately below the top edge portion of an essentially aligned parallel to the top of the panel parallel support surface and the lower side panel portion in the area which is in an adjacent panel inwardly pivoted state the supporting surface in contact , that have approximately below the upper side panel section, a corresponding aligned correspondence plane surface. The convex curvature can thereby pass into the parallel-aligned support surface without forming an inflection point. but it is also quite possible that in the transition from a convex curvature to collimated supporting surface a kink point.
The protrusion may have a pointing towards the free end of the tongue surface and between the surface and the overall genüberliegenden region of the groove, a clearance exist.
In addition, the spring at its lower tongue surface, preferably in the range of the free end of the spring, a locking element and the lower side panel portion may have a top side cooperating with interconnected panels with the locking element of the adjacent panel locking recess. This configuration gives the compound in the pivoted condition overall even greater stability and makes an unintentional pivoting.
Alternatively, a reverse arrangement may be provided. Here, the spring at its lower tongue surface, preferably in the region of the free end of the spring, a locking recess having a panel portion and the lower-side at the upper side panels connected together with the locking recess of the adjacent panel have cooperating locking element.
Naturally, it is also possible that a locking element is provided on both the lower spring surface of the spring as well as the upper side to the lower side panel section each, wherein each locking element is assigned in the top surface of the lower side panel section respectively in the lower spring face a corresponding locking recess.
The upper tongue surface can be aligned approximately parallel to the top of the panel. Also, an inclined plane orientation is also conceivable. However, it is also quite possible that the upper tongue surface is arched towards the top or the bottom. The adjacent to the upper tongue surface in the pivoted state region of the adjacent panel, extending between the upper side panel portion and the mating surface of the recess is designed such that a pivoting and locking is possible.
The lower tongue surface can comprise at least one projecting portion and in the lower side panel portion can each be assigned a projecting portion, a connecting two adjacent panels enabling by pivoting corresponding recess. Of course, several protruding portion may be provided, each associated with a recess. Through the above ranges, an additional locking can be realized in the direction perpendicular to the top surface of the panels, depending on the configuration of the protruding portion.
In addition, a laterally protruding portion can be formed and in the upper side panel portion and / or in the upper edge portion except for a corresponding aperture may be provided at the upper edge portion and / or on the upper side panel portion.
a pressing member may be provided at least on the lower tongue surface and / or on the upper side of the lower side panel portion that is in the pivoted state of two adjacent panels with the opposite area of the adjacent panel in contact.
In the following, embodiments of the invention illustrated in the drawings are explained. In the drawings: Figure 1 is a partial section through two panels according to the invention in the locked state without a pointing towards the top Nutwandungsbereich.
Fig. 2 is a partial section through two panels according to the invention in the non-locked state,
Fig. 3 - 5 is a partial section through two panels according to the invention in the locked state,
Fig. 6 shows the Einschwenkvorgang shown in five different positions,
Fig. 7 - 9, different embodiments of a panel according to the invention and
Fig. 10 - 22 further embodiments in the locked state.
In all figures, the same reference numerals are used for identical or similar components.
In the figures, the panels are shown, having a top 1 and a lower side. 2 On the top one usually has a decorative layer not shown is located.
The panels can be used for example as floor panel. Adjacent panels may thereby by a pivoting movement, as it is shown in Figure 5, are locked together. In order to lock the panels have suitable means. Thus, a projecting tongue 3 with a spring lower surface 4 and an upper tongue surface 5 is provided at the first longitudinal and / or a first transverse edge of each via the respective longitudinal and / or transverse edge.
For example, as in Fig. 1 shown in the right panel, the panel divides the spring 3 in a lower edge portion 6 and an upper edge portion 7. The lower edge portion 6 is set back relative to the upper edge section 7.
The opposite edge is formed so as to correspond to the spring. 3 Therefore, a groove 8 is provided here, which is surrounded by an upper side panel portion 9 and a lower-side panel portion 10th The lower-side panel portion 10 is formed to protrude over the upper side panel portion. 9
In which in Figs. 1 and exemplary embodiments illustrated 11 to 13, 16 and 18, the lower tongue surface 4 in the region adjacent to the lower edge portion 6 at a region parallel to the top 1 aligned portion. In the area of the free end portion of the lower surface 4 of the spring 3 is convex. The lower tongue surface 4 is formed convexly curved in the embodiments according to FIGS. 2 to 9 and 14 to their substantial length. In Fig. 10, the lower spring surface is 4 aligned in two mutually inclined surfaces 4a and 4b. In Fig. 15, the lower tongue surface 4 is also convex only in the region of the free end.
The lower spring surfaces 4 in the embodiments of FIGS. 11 and 13 are each aligned substantially parallel to the upper side 1, wherein each lower Federflä- surface 4 in the region of its two ends in the direction of the top face 1 is formed tapered.
In the embodiments according to FIGS. 2 to 11, 13, 15 and 17, 10, the lower side panel section a pointing in the direction of the upper side 1 of the panel projecting Nutwandungsbereich 11 which has a parallel to the top 1 extending upper-side surface, for example, in Fig. 11 , The Nutwandungsbereich 11 acts in Figs. 2 to 11 and 13 together in the connected state of two panels by pivoting with an undercut 12 of the adjacent panel. In Fig. 15 illustrates a variant in which the Nutwandungsbereich 11 is located without contact inside the edges of the undercut 12 of the adjacent panel. However, it is also conceivable that the lower surface 4 on the upper side spring rests on the Nutwandungsbereich 11 by way of a support.
In the embodiments shown in Figures 2 to 9 and 14 embodiments, the lower spring surface 4 is formed convex, whereas the upper tongue surface is oriented parallel to the top surface of the panel 1 approximately. 5 As can be seen from the figures, in the exemplary embodiments illustrated here, the upper tongue surface 5 is much shorter and smaller than the lower tongue surface. 4
In the illustrated in the figures embodiments, a projection 13 is provided on the spring 3 at its upper tongue surface 5, which has a rearwardly facing in the direction of the upper edge portion 7 contacting surface 14, and a pointing towards the free end of the spring 3 toward surface 14a. The upper side panel portion 9 of the adjacent panel on the underside has a projection 13 corresponding with the recess 15 with a counter surface sixteenth In the pivoted state, the counter surface 16 cooperates with the contact surface fourteenth In this way the panels in the connected state by pivoting due to the cooperation of the contact surface 14 and opposite surface 16 are drawn against each other so that a gap-free connection between adjacent panels is made in the area of the top. 1 Here, the connection in the direction of a related to the orientation of the surfaces of the edge portions perpendicular (arrow S) is free of play.
When in Figs. 1, 14, 15, 18 to 22 illustrated embodiments, two adjacent panels are moved exclusively by the cooperation of the contact surface 14 and opposite surface 16 against each other.
In the example shown in the figures 2 to 11, 13 and 17 embodiments, two adjacent panels are far locked twice, as on the one hand a positive fit between the projection 13 and the recess 15 and on the other hand, a positive connection between the Nutwandungsbereich 11 of the lower side panel section 10 and the undercut 12 takes place.
In the illustrated in Fig. 1 and 2 embodiments of the projection 13 and the recess 15 are configured in three ecksförmig approximately. This is also the case in the figures 3 to 6 and 10 to 15 °.
In the figures 7 to 9, other embodiments are shown. Thus, in Fig. 7 is an approximately semicircular recess, and provided in Fig. 9 is a rectangular recess DAR. Fig. 9 shows an embodiment in which only the counter surface 16 is planar, while the remaining contour of the recess is curved 15th
For a good lock, it is advantageous if the contact surface 14 has a sufficient slope so that the panels are drawn toward each other when swinging due to the cooperation of the contact surface 14 and opposite surface sixteenth
In the illustrated example in Fig. 5 embodiment, the upper edge portion 7 is formed set back in the region adjacent to the upper surface 5 of the spring portion. A similar return also has the top-side panel section 9 of the adjacent panel. This creates a cavity 17. The circular path of the convexly shaped lower tongue surface 4 of the spring 3 in FIG. 5 has different radii A, B.
In FIGS. 3 and 4 an embodiment is shown in which a locking element 18 is provided to the spring 3 at its lower tongue surface 4 that engages with a top side disposed in the lower side panel section 10 locking recess 19th Figure 13 shows an embodiment in which the two locking elements 18 and to the lower side panel portion 10, two locking recesses 19 are provided at the lower surface of the spring 4 on the upper side.
In Fig. 12, a reverse arrangement is depicted. Here, the upper side is provided at the lower side panel portion 10, three locking elements 18, which engage in corresponding locking recesses 19 in the lower surface of the spring. 4
The locking member 18 may be formed as a spring relative to the lower surface 4 of the spring 3 projecting molded area. Alternatively, the locking element 18 can also serve as part of the spring 3 as shown in Fig. 4, produced by an undercut region, and thus are within the circular path of the lower spring surface 4.
In the illustrated in Fig. 3 embodiment, the cross-section of the locking element is curved in about 18 constructed and arranged in the portion of the lower spring surface 4 adjacent to the undercut 12th
In the illustrated in Fig. 4 embodiment, the locking element 18 in the region of the free end of the spring 3 and the locking recess 19 is provided in the corresponding area in the lower side panel portion 10th
The laying, ie the pivoting-in, is in the five views according to Fig. 6 illustrates. As these figures it can be seen, the panels can be locked in place by a simple pivotal movement against each other.
In Figs. 7 and 9 respectively on the one hand and Fig. 8 on the other hand are different configurations of the spring adjacent to the top surface 5 portion 20 which extends between the upper side panel portion 9 and the counter surface 16 of the recess 15, is shown. Thus, in Fig. 8, the abutting portion 20 is formed obliquely, and FIGS. 7 and 9 illustrate a parallel alignment of the adjacent area 20 to the upper side 1.
For example, in Fig. 7, an embodiment is shown in which the Nutwandungsbereich 11 comprises from the bottom 2 of the panel a distance greater than the region 20 in front of the bottom. Thus, the groove 8 - seen parallel to the upper and lower surfaces 1, 2 in the - direction covered by the Nutwandungsbereich. 11 In Fig. 9, the upper-side surface of the Nutwandungsbereichs 11 approximately with the region 20 is aligned. Other embodiments, as shown for example in Fig. 8, are of course conceivable. Here, the groove is only partially 8 from the Nutwandungsbereich 11 - seen parallel to the upper and lower surfaces 1, 2 in the direction of - concealed.
In the case of in Figs. 1 and exemplary embodiments illustrated 11 to 13 and 18, the lower tongue surface 4 is formed to a large extent substantially parallel to the upper surface 1, wherein the lower side panel portion 10 is formed on the top side accordingly. In Figs. 11 and 13, a Nutwandungsbereich 11 is formed on the lower side panel section 10 in addition, which is formed like a web pointing to form two parallel side edges upwards. When swinging in and out the lower side panel portion 10 moves to a certain extent downwards. In the locking position, as shown in FIGS. 11 and 13, the lower side panel portion 10, however, has again assumed its original position.
It is obvious that the (the) locking member (s) 18 and / or the projection 13, as shown in the figures, one piece can be trained det with the respective panel (can). Of course, a two-piece arrangement is also conceivable, wherein the (the) locking member (s) 18 and / or the protrusion 13 by suitable connecting techniques, such. B. bonding, is connected with the respective panel (are).
In the illustrated in Fig. 15 embodiment, the projecting Nutwandungsbereich 11 of the lower side panel section 10 is thus in the undercut 12 of the adjacent panel, that the surfaces of the Nutwandungsbereiches not stand 11 with the corresponding surfaces of the undercut 12 in contact.
The spring 3 is formed at its lower tongue surface 4 only in the region of its free end towards the lowest point of the spring 3 convex. The convex configuration begins at the lowest point of the spring 3, and rises in the direction of the free end of the spring. 3
The lower spring surface 4 of the spring 3 has at the lowest point, that is, in this embodiment, approximately below the top edge portion 7, a substantially aligned parallel to the top surface 1 of the panel supporting surface 21 (level "x") and the lower-side panel section 10 in the region in an adjacent panel with the pivoted state the supporting surface 21 in contact, ie to approximately below the upper side panel section 9, a corresponding aligned correspondence plane surface 22nd
The width A of the bearing surface 21 is smaller than the width B of the correspondence face 22, in this embodiment, so that even in this embodiment, a pulling apart of two panels only through the interaction effect of counter-surface 16 and contact surface is prevented fourteenth
The projection 13 has a pointing towards the free end of the spring 3 surface 14a. Between the surface 14a and the opposed portion lβa the groove 8 is a gap-like space 23 which also extends partially in the illustrated embodiment, the free end of the spring 3 around in the area between the lower tongue surface 4 and the adjacent panel.
In the embodiments of FIGS. 1, 14 and 15, a pulling apart of two panels in the direction S only by the cooperation of the contact surface 14 and opposite surface 16 is prevented.
A compression, ie a further Gegeneinanderschie- ben, two connected panels is prevented by the interaction on the one hand between the upper edge portion 7 and the upper side panel portion 9 and on the other hand between the lower tongue surface 4 in the region of the convex curvature, and the groove 8 of the adjacent panel.
Displacing two mutually locked panels in an aligned perpendicular to the bottom 2 of the panel direction is prevented by the interaction on the one hand between the contact surface 14 and opposing surface 16 and on the other hand between the lower tongue surface 4 in the region of the convex curvature, and the groove 8 of the adjacent panel.
In the illustrated in Fig. 16 embodiment, the lower surface 4 of the spring spring is convex at the free end 3, said convex configuration to the lower edge portion 6 blends into a plane parallel to the top surface 1 orientation. In this parallel-oriented area, a locking element is provided in approximately rectangular cross-section 18 at the lower side of the lower spring surface 4, the gelungsausnehmung been aged in an appropriate Verrie- 19 in the lower side panel portion 10th In the locked state is pointing in the direction of the lower edge portion 6 operative surface 24 of the locking element 18 and a corresponding locking surface 25 of the locking recess 19 in contact. Thus, a dual locking takes place to the extent that on the one hand, the contact surface 14 and the counter surface 16 and on the other hand, the effective surface 24 and the locking surface 25 cooperate with each other.
In Fig. 17 an alternative configuration of the embodiment of Fig. 2 is shown. While the top side has an aligned parallel to the bottom surface 2 in Fig. 2 of the Nutwandungsbereich 11, in Fig. 17 of the Nutwandungsbereich 11 is designed tapering towards the top. The provided in the adjacent panel undercut 12, which cooperates with the Nutwandungsbereich 11, likewise has a triangular approximately embodiment, but which is made wider toward the lower edge portion 6 so that the extent between the free end of the lower side panel section 10 and the opposite area of the adjacent panel log remains to the bottom 2 of the panel towards widening gap.
In Fig. 18 an alternative embodiment of FIG. 1 is shown. Here, a recess 26 is provided in the lower spring surface 4 in the direction parallel to the underside 2 of area.
In the example shown in Fig. 19 embodiment, the upper-side and lower-side panel portion 9, 10 in approximately aligned. The lower edge portion 6 is only slightly offset from the upper edge portion. 7 The lower tongue surface 4 comprises, inter alia, a substantially oriented parallel to the underside 2 of the panel area and then increases towards the free end at an angle. In order to facilitate the pivoting, the spring of the lower surface is slightly bevelled 4 facing corner of the lower side panel section 10 degrees.
Fig. 20 shows a further embodiment in which the upper side panel portion 9 is formed salient with respect to the lower side panel portion 10th In this embodiment the lower spring surface 4 is step-like, in two stages in the illustrated embodiment, is formed to form a projecting portion 27th This projecting portion 27 includes two aligned substantially parallel to the bottom 2 faces. In the locked state, the projecting portion 27 engages in the adjacent panel in a corresponding recess 28th
In the illustrated in Fig. 21 embodiment, a laterally projecting portion 29 is formed on the upper edge portion 7 which has a substantially 1 to the upper side aligned parallel to and facing the top surface 30 1. The adjacent panel 31 has a similarly parallel to the top 1 oriented in approximately abutting surface 32 on a corresponding exception opening in the upper side panel portion. 9 In einge- pivoted state, the surface 30 of the projecting portion 29 abuts the abutment surface 32 of the receiving opening 31 so that an additional locking is ensured perpendicular to the upper side 1 of the panels.
In Fig. 22 an embodiment is shown in which the upper-side and lower-side panel portion 9, 10 are aligned. The spring 3 is in the direction of its free end toward a smaller width than the width of the groove 8, so that a free space 33 is formed in the inwardly pivoted state between the spring lower surface 4 and the lower side panel portion 10th Therefore, a pressing element is on the upper side of the lower side panel section 10 in the region in which the clearance 33 is additionally provided 34, which is connected to the spring lower face 4 in the pivoted state into contact. Thereby, a force in the direction of the arrow 35 is exerted in the swung-in state of the pressing member 34 on the spring. 3
