Abstract:
A floor board of elongated rectangular shape, which comprises a plurality of couplers at its side edges and arranged to be connected to other similar floor boards to form a floor that is made up of a plurality of adjacent, parallel rows of juxtaposed floor boards and in which the floor boards of one and the same row are interconnected short side to short side and the floor boards of adjacent rows are interconnected long side to long side, the plurality of couplers having a first pair of couplers comprising a first female coupler and a first male coupler extending along first and second long side edges of the floor board, respectively, and a second pair of couplers comprising a second female coupler and a second male coupler extending along first and second short sides of the floor board, respectively,wherein the first and second female couplers in at least one of the two pairs of couplers comprise a first coupling element that projects laterally from a first long side edge/short side edge and extends along this edge at a level below the upper surface of the floor board and having an upwardly open groove extending along the first coupling element and an upper portion with a lower surface that extends obliquely upwards and over the groove a short distance from the inner limiting wall thereof so as to form a stop, and wherein the first and second male couplers in at least one of the two pair of couplers comprises a second coupling element that has substantially the shape of an upwardly open V and extends along a second long side edge/short side edge in a longitudinal recess formed in the lower portion thereof, the outer V-leg of the second coupling element being springingly foldable in the direction of the inner V-leg of the second coupling element, and wherein the external V-shape of the second coupling element in its nondeformed state is substantially complementary to the shape of the groove of the first coupling element, and wherein the first and second coupling elements being located in such manner that, when interconnecting two similar floor boards, the groove in the first coupling element of one of the floor boards is situated directly under the substantially V-shaped second coupling element of the other floor board when the floor boards are in such a position relative to each other that their side edges facing each other are vertically aligned, and further wherein two floor boards are interconnectible by pressing the second coupling element of the other floor board down into the first coupling element of the one floor board, whereby the outer V-leg of the second coupling element is springingly folded, the V-leg springing back to its initial position and snapping in under the stop once the second coupling element has been inserted into the first coupling element.
