Panel and covering

A panel, in particular a floor panel, comprising:

• a. at least one first coupling part and at least one second coupling part arranged on opposite sides of the panel, wherein the first coupling part of said panel and the second coupling part of another panel are arranged to be coupled with a downward motion;
• b. wherein the first coupling part comprises an upward tongue, at least one upward flank lying at a distance from the upward tongue and an upward groove formed in between the upward tongue and the upward flank, wherein the upward groove is adapted to receive at least a part of a downward tongue of the second coupling part of another panel, wherein the side of the upward tongue facing towards the upward flank is an inside of the upward tongue and the side of the upward tongue facing away from the upward flank is an outside of the upward tongue;
• c. wherein the second coupling part comprises a downward tongue, at least one downward flank lying at a distance from the downward tongue, and a downward groove formed in between the downward tongue and the downward flank, wherein the downward groove is adapted to receive at least a part of the upward tongue of the first coupling part of another panel, wherein the side of the downward tongue facing towards the downward flank is an inside of the downward tongue and the side of the downward tongue facing away from the downward flank is an outside of the downward tongue;
• d. wherein the outside of the downward tongue and the upward flank both comprise an upper contact surface extending from a topmost side of the panel, wherein:
• (i) both of said contact surfaces entirely extend vertically or
• (ii) the upper contact surface of the downward tongue extends in vertical direction and wherein the upper contact surface of the upward flank is downwardly inclined in a direction away from the upward tongue,
• wherein the upper contact surface of the outside of the downward tongue of said panel is configured to engage the upper contact surface of the upward flank of an adjacent panel, in coupled condition of said panels wherein the upper contact surfaces are the upper surfaces where two panels are in contact;
• e. wherein, below the upper contact surfaces, both the downward tongue and the upward flank comprise an inclined contact surface, wherein the inclined contact surface of the downward tongue of said panel is configured to engage the inclined contact surface of the upward flank of an adjacent panel, in coupled condition of said panels, wherein each vertical part of the upper contact surfaces and each adjoining inclined surface mutually enclose the same angle (a) between 100 and 175 degrees, wherein the vertical upper contact surface of the upward flank adjoins the inclined contact surface of the upward flank;
• f. wherein, adjoining the inclined contact surface, the downward tongue comprises an outer surface, situated below the inclined contact surface of the downward tongue, and wherein, adjoining the inclined contact surface, the upward flank comprises an inner surface, situated below the inclined contact surface of the upward flank, wherein the outer and inner surface run substantially parallel and extend in a vertical direction;
• g. wherein, in coupled condition of adjacent panels, a space is present between at least a part of the outer surface of said panel and at least a part the inner surface of an adjacent panel;
• wherein, in coupled condition of adjacent panels, the upper contact surfaces define an inner vertical plane, wherein the inclined contact surfaces are positioned at a side of said inner vertical plane facing away from the upward tongue.
