A surface element designed to be assembled together with similar surface elements to form a plurality of joined surface elements: the surface element comprising a decorative upper surface, an opposed lower surface and at least four edges disposed between the upper and lower surfaces, said lower s
1. A surface element designed to be assembled together with similar surface elements to form a plurality of joined surface elements: the surface element comprising a decorative upper surface, an opposed lower surface and at least four edges disposed between the upper and lower surfaces, said lower surface defining a plane;the four edges comprising a first edge and a second edge defining a first pair of opposite sides, and a third edge and a fourth edge defining a second pair of opposite sides;the four edges including upper edge portions, towards which the surface elements seen from above visually extend in joined condition;wherein the first edge of the surface element comprises a first male joining member and the second edge comprises a first female joining member;the first male joining member comprising a distally extending tongue and the first female joining member comprising a groove which is bordered by an upper lip and a lower lip, said lower lip forming a lower cheek extending in distal direction further than said upper lip;the first male joining member and the first female joining member being configured such that two of such surface elements can be coupled and vertically as well as horizontally locked at their respective first and second edges;the vertical locking being realized in that the tongue fits in the groove, said tongue and groove providing a positive vertical locking, said tongue thereto extending with a distal length underneath the upper lip, said length being such that joining of the tongue and groove by only a plane-parallel substantial vertical lowering of one surface element in respect to the other is made impossible;the horizontal locking being realized by an upwardly directed lip at said lower cheek and a lower side groove at the edge comprising the tongue, said upwardly directed lip and said lower side groove having contact surfaces for realizing said horizontal locking;said lower side groove at a distal side thereof being bordered by a lower side protrusion at said tongue, said protrusion having a lowermost portion;said lowermost portion being located proximally from a vertical plane through the upper edge portion belonging to said first edge;wherein the third edge of the surface element comprises a second male joining member and the fourth edge comprises a second female joining member;wherein the third and fourth edges of two of such surface elements when coupled define a vertical closing plane;said second male joining member and second female joining member of the surface element being configured such that two of such surface elements at their respective third edge and fourth edge seen in a vertical cross-section perpendicular to said closing plane can be coupled to each other by a non-rotational downward motion of one surface element in respect to the other surface element, wherein said non-rotational downward motion seen in said cross-section is substantially parallel to said vertical closing plane;said second male joining member being formed as an upper cheek protruding at said third edge and provided with a downward directed portion;said second female joining member being formed as a lower cheek protruding at said fourth edge and provided with an upward directed portion;said second male joining member comprising a male cheek surface at a lower side of said upper cheek and said second female joining member comprising a female cheek surface at an upper side of said lower cheek, the male and female cheek surfaces being arranged to interact with one another so that two joined adjacent floor elements become locked to each other in a horizontal direction;said third and fourth edges each comprising one or more locking surfaces for locking the third edge and a fourth edge of two of such coupled surface elements against vertical separation;wherein said one or more locking surfaces for locking the third edge and fourth edge against vertical separation define one or more snapping hooks and undercuts configured to engage by a snapping action through said non-rotational downward motion, and when engaged preventing vertical separation of the third edge and fourth edge;wherein said lower cheek of the second edge is formed in one piece of a core material of the surface element;wherein the contact surfaces at the first male and first female joining members in the coupled condition define at least one first tangent line making an angle with said plane;wherein the male and female cheek surfaces at the second male and second female joining members in the coupled condition of two of such surface elements define at least one second tangent line making an angle with said plane; andwherein said angle defined by said one first tangent line is different from said angle defined by said one second tangent line. 2. The surface element of claim 1, wherein the angle of the second tangent line is larger than the angle of the first tangent line, such that the second tangent line with respect to said plane is steeper than said first tangent line. 3. The surface element of claim 2, wherein said angle of the first tangent line as well as said angle of the second tangent line are different from 90 degrees. 4. The surface element of claim 3, wherein the contact surface of the first female joining member is upwardly directed from a proximal to a distal position. 5. The surface element of claim 4, wherein the female cheek surface of the second female joining member is upwardly directed from a proximal to a distal position. 6. The surface element of claim 1, wherein the joining members at the first, second, third and fourth edges are configured such that the joining motion that is required for joining the surface element with its first edge to a second edge of a similar adjacent second surface element, automatically results in the joining of the surface element with its third edge to a fourth edge of an adjacent third surface element. 7. The surface element of claim 1, wherein also the lower cheek of the fourth edge is formed in one piece of said core material. 8. The surface element of claim 1, wherein said contact surfaces for realizing said horizontal locking at the first pair of opposite sides are substantially planar. 9. The surface element of claim 1, wherein said contact surfaces for realizing said horizontal locking at the first pair of opposite sides are curved. 10. The surface element of claim 1, wherein the second male joining member and the second female joining member are formed in one piece from said core material.
