Abstract

A rectangular panel has long and short edges, such that on each long edge and on each short edge, the panel has a coupling part, which allows the panel to be coupled to another similar panel.

First claim

1 .- 38 . (canceled)

39 . A panel which is rectangular and has long and short edges,
wherein, on each long edge and on each short edge, the panel comprises a coupling part which allows the panel to be coupled to another similar panel; wherein the coupling part on the one long edge comprises a tongue and a downwardly directed interlocking groove; wherein the coupling parts on the other long edge and on the short edges each comprise a groove and an interlocking lip; wherein the interlocking lip on each of the other long edge and the short edges delimits the respective groove along the bottom and comprises an upwardly directed interlocking element; wherein the tongue is configured to cooperate with the groove on each of the other long edge and the short edges of another similar panel in order to produce a vertical interlocking between the respective edges; and wherein the downwardly directed interlocking groove is configured to cooperate with the upwardly directed interlocking element on each of the other long edge and the short edges of another similar panel in order to produce a horizontal interlocking between the respective edges.

40 . The panel of claim 39 , wherein the interlocking lip on the other long edge is absent along a portion of the other long edge;
wherein, at the location of the aforementioned portion, the coupling part on the other long edge comprises a downwardly directed interlocking groove; and wherein the downwardly directed interlocking groove on the other long edge is configured to cooperate with the upwardly directed interlocking element on the one and/or other short edge of another similar panel in order to produce a horizontal interlocking between the respective edges.

41 . The panel of claim 39 , wherein the interlocking lip on the one and/or other short edge is absent along a portion of the respective short edge;
wherein the coupling part on the respective short edge comprises a downwardly directed interlocking groove at the location of the aforementioned portion; and wherein the downwardly directed interlocking groove on the respective short edge is configured to cooperate with the upwardly directed interlocking element on the other long edge of another similar panel in order to produce a horizontal interlocking between the respective edges.

42 . The panel of claim 39 , wherein the interlocking lip on each of the short edges is absent along a portion of the respective short edge;
wherein the coupling part on each of the short edges comprises a downwardly directed interlocking groove at the location of the respective aforementioned portion; and wherein the downwardly directed interlocking groove on the one and other short edge is configured to cooperate with the upwardly directed interlocking element on the other and one short edge of another similar panel, respectively, in order to produce a horizontal interlocking between the respective edges.

43 . The panel of claim 39 , wherein the interlocking lip on the one and/or other short edge is present along the entire or virtually the entire length of the one and/or the other short edge, respectively.

44 . The panel of claim 39 , wherein the coupling part on the one long edge is present along the entire or virtually the entire length of the one long edge.

45 . The panel of claim 39 , wherein the groove on the other long edge is present along the entire or virtually the entire length of the other long edge.

46 . The panel of claim 39 , wherein the groove on the one and/or other short edge is present along the entire or virtually the entire length of the one and/or other short edge, respectively.

47 . The panel of claim 39 , wherein the coupling part on the one and/or other short edge comprises a further interlocking element;
wherein the coupling part on the other long edge comprises a further interlocking element; and wherein the further interlocking element on the other long edge is configured to cooperate with the further interlocking element on the one and/or other short edge of another similar panel in order to produce a vertical interlocking between the respective edges.

48 . A panel which is rectangular and has long and short edges wherein, on each long edge and on each short edge, the panel comprises a coupling part which allows the panel to be coupled to another similar panel;
wherein the coupling parts on the one long edge and on both short edges comprise a tongue and a downwardly directed interlocking groove; wherein the coupling part on the other long edge comprises a groove and an interlocking lip; wherein the interlocking lip on the other long edge delimits the respective groove along the bottom and comprises an upwardly directed interlocking element; wherein the groove is configured to cooperate with the tongue on each of the one long edge and the short edges of another similar panel in order to produce a vertical interlocking between the respective edges; and wherein the downwardly directed interlocking groove of the one long edge and of both short edges is configured to cooperate with the upwardly directed interlocking element on the other long edge of another similar panel in order to produce a horizontal interlocking between the respective edges.

49 . The panel of claim 48 , wherein the tooth and the interlocking groove on the one long edge is absent along a portion of the one long edge;
wherein, at the location of the abovementioned portion, the coupling part on the one long edge comprises a groove with an interlocking lip with an upwardly directed interlocking element); and wherein the upwardly directed interlocking element on the one long edge is configured to cooperate with the downwardly directed interlocking groove on the other long edge and/or on the short edges of another similar panel in order to produce a horizontal interlocking between the respective edges.

50 . The panel of claim 48 , wherein the tongue and the downwardly directed interlocking groove on the one and/or other short edge is absent along a portion of the respective short edge;
wherein the coupling part comprises a groove and an interlocking lip on the respective short edge; and wherein the groove and the interlocking lip on the respective short edge are configured to cooperate with the tongue and the downwardly directed interlocking groove on the one long edge of another similar panel in order to produce a horizontal interlocking between the respective edges.

51 . The panel of claim 48 , wherein the tooth and the downwardly directed interlocking groove on each of the short edges is absent along a portion of the respective short edge;
wherein, at the location of the respective abovementioned portion, the coupling part on each of the short edges contains a groove and an interlocking lip; and wherein the groove and an interlocking lip on the one and the other short edge are configured to cooperate with the tongue and the downwardly directed interlocking groove, respectively, on the other and one short edge of another similar panel in order to produce a horizontal interlocking between the respective edges.

52 . The panel of claim 48 , wherein the tongue and the downwardly directed interlocking groove on the one and/or other short edge is present along the entire or virtually the entire length of the one and/or the other short edge, respectively.

53 . The panel of claim 48 , wherein the coupling part on the one long edge is present along the entire or virtually the entire length of the one long edge.

54 . The panel of claim 48 , wherein the groove on the other long edge is pr
