Panel

A panel system comprising:

• an upper surface, a lower surface and at least one pair of opposite edges;
• wherein the at least one pair of opposite edges comprises a first edge having a first joint profile and a second edge having a second joint profile;
• wherein the first and second joint profile define coupling parts allowing that two of such panels can be joined by a downward movement of the first edge of one panel in respect to the second edge of another panel, wherein the coupling parts in a coupled condition provide a locking in a direction perpendicular to a plane of the two of such panels as coupled, as well as in a direction parallel to the plane of the coupled panels and perpendicular to respective edges;
• wherein the first joint profile comprises a first laterally projecting lip with a downward projecting locking part, the downward projecting locking part defining a male part;
• wherein the second joint profile comprises a second laterally projecting lip with an upward projecting locking part, the upward projecting locking part defining proximally thereof a recess configured as a female part;
• wherein the first laterally projecting lip with the downward projecting locking part defines a downward directed hook, whereas the second laterally projecting lip with the upward projecting locking part defines an upward directed hook;
• wherein, in a coupled condition of two of such panels, the downward directed hook and upward directed hook engage behind each other to prevent drifting apart of the two of such panels;
• wherein the coupling parts further comprise vertically active locking portions which at least define a first point of contact and a second point of contact, the first and second points of contact being located at opposite sides of the male and female parts;
• wherein the vertically active locking portions comprise a first locking portion and a second locking portion at respective opposite sides of the male part and a third locking portion and a fourth locking portion at the respective opposite sides of the female part;
• wherein the first and third locking portions in the coupled condition of two of such panels define the first point of contact and have contact surfaces that in the coupled condition of two of such panels define an inclined tangent line;
• wherein the second and fourth locking portions in the coupled condition of two of such panels define the second point of contact and have contact surfaces that in the coupled condition of two of such panels define an inclined tangent line;
• wherein the male part has a distal side and a proximal side, the second locking portion being located at the distal side;
• wherein the panel at the first edge has a distal edge defining a closing plane of the panels, the second locking portion being located in an inwardly offset position in regard to the distal edge;
• wherein the joint profiles are realized in one piece from a panel material;
• wherein measured according to a direction perpendicular to a plane defined by two of such panels, the second point of contact is closer to the plane defined by the upper surface of the panels than the first point of contact;
• and
• wherein the vertically active locking portions are configured such that in respect to a plane of two coupled floor panels, a tangent line at the first point of contact is steeper than a tangent line at the second point of contact.
