Panels with coupling means
The invention relates to panels comprising coupling means which permit the panels to be interconnected by form fit. A first panel comprises a projecting edge positioned laterally on its underside as the coupling element. A second panel comprises a projecting edge positioned laterally on its upper side as the coupling element. One of the aforementioned edges has a first projecting locking element which engages in a corresponding first cavity or recess of the other edge when the two panels are joined together. The panels comprise additional coupling elements which lock the panels by form fit in a vertical direction, in relation to the surface of said panels. The coupling elements are configured in such a way that one panel can be connected to the other panel by form fit, by lowering the former in relation to the latter. Two panels of the aforementioned type can be interconnected without adhesive in a particularly rapid manner.
1. Panels with coupling elements, allowing an interlocking form-fitting connection between the panels comprising first and second panels each provided with coupling elements on one side such that the first panel can be connected form-fittingly to the second panel by a rotary movement around a connecting joint, and wherein
the first panel comprises on a further side a projecting flank laterally on the bottom side as an additional coupling element, and
the second panel comprises on a further side a projecting flank laterally on the top side as an additional coupling element, and
the projecting flank on the top side comprises a first projecting locking element engaging in a corresponding first recess or indentation in the other flank in the joined state of the panels,
which projecting flanks of the panels comprise further coupling elements, locking the panels in an interlocking manner in the vertical direction relative to the surface of the panels, wherein
the additional coupling elements are configured such that the first panel can be connected in an interlocking manner by a lowering relative to the second panel without a rotary movement around a connecting joint of said additional coupling elements, and further comprising a laterally applied groove on one panel and a laterally attached tongue in another panel, wherein the tongue engages in the groove in the joined state, one flank of the groove is longer than the other flank, the longer flank comprises a recess, the tongue comprises a projecting nose on a bottom or top side, the nose and the recess are arranged such that the nose can latch in the recess, and the side of the tongue comprising the nose comprises a recess, so a gap remains between the side of the tongue comprising the nose and the longer flank of the groove in the joined state of the two panels owing to the recess formed so the open end of the tongue does not touch the projecting flank when the two panels are joined.
2. Panels according to claim 1 , wherein as coupling elements, configured such that one panel can be connected in an interlocking manner by lowering relative to the other panel, a second projecting locking element and a second indentation are provided.
3. Panels according to claim 2 , wherein as coupling elements, configured such that one panel can be connected in an interlocking manner by lowering relative to the other panel, a third projecting locking element and a third indentation are provided.
4. Panels according to claim 1 , comprising tapering at an open end of the first projecting locking element.
5. Panels according to claim 1 , comprising a bevel at an open end of the flank attached to the bottom side.
6. Panels according to claim 1 , comprising an incision in the first projecting locking element, so the open end of the first projecting locking element can be compressed.
7. Panels according to claim 1 , wherein the projecting flank on the top side of the second panel rests on the projecting flank on the bottom side of the first panel in the joined state.
8. Panels according to claim 1 , wherein gaps between the coupling elements are provided in such a way that there remains no play between the panels in the connecting joint.
9. Panels according to claim 1 , wherein the nose of the tongue extends to the base of the corresponding recess in the joined state.
10. Panels according to claim 1 , wherein the side of the tongue comprising the nose does not touch the projecting flank inside the groove owing to the provision of a recess, when the panels are joined, so a gap remains.
11. Panels according to claim 1 , comprising a funnel-like aperture in wherein the first indentation has a tapered inlet.
12. Panels according to claim 1 , wherein the recess is in the form of a bevel.
