First Claim
1. A substantially planar floor element having at least a first edge and a second edge, a lower side and an upper decorative layer, said first edge comprising an undercut and an upper cheek surface at least partially defining a tongue, said second edge comprising at least one snapping hook and a lower cheek surface, wherein a radially projected length (L) of the undercut is less than or equal to a horizontal rotated radially projected height (H) of the upper cheek surface such that when said first edge is mated to a corresponding second edge on an adjacent floor element through substantially vertical motion, said undercut on said floor element unites with the snapping hook on the adjacent floor element and said upper cheek surface unites with the lower cheek surface of the adjacent floor element to prohibit at least vertical separation of the floor element and the adjacent floor element, wherein the size and shape of each of said undercut, upper cheek surface, at least one snapping hook and lower cheek surface requires mating by only vertical motion.

Abstract
Flooring material comprising sheet-shaped floor elements with a mainly square or rectangular shape. The floor elements are provided with edges, a lower side and an upper decorative layer. The floor elements are intended to be joined by means of joining members. The floor elements are provided with male joining members on a first edge while a second edge of the floor elements are provided with a female joining member. The male joining member is provided with a tongue and a lower side groove while the female joining member is provided with a groove and a cheek, the cheek being provided with a lip. The floor elements are provided with a male vertical assembly joining member on a third edge while a fourth, opposite, edge is provided with female vertical assembly joining member. The floor elements are alternatively provided with a male vertical assembly joining member on a third edge while a fourth, opposite, edge also is provided with male vertical assembly joining member. Adjacent male vertical assembly joining members are hereby joined by means of a separate vertical assembly joining profile. Two adjacent edges of a floor element can hereby, at the same time, and in the same turning motion, be joined with a floor element adjacent to the first edge and a floor element adjacent to the third or fourth edge.

- 1. A substantially planar floor element having at least a first edge and a second edge, a lower side and an upper decorative layer, said first edge comprising an undercut and an upper cheek surface at least partially defining a tongue, said second edge comprising at least one snapping hook and a lower cheek surface, wherein a radially projected length (L) of the undercut is less than or equal to a horizontal rotated radially projected height (H) of the upper cheek surface such that when said first edge is mated to a corresponding second edge on an adjacent floor element through substantially vertical motion, said undercut on said floor element unites with the snapping hook on the adjacent floor element and said upper cheek surface unites with the lower cheek surface of the adjacent floor element to prohibit at least vertical separation of the floor element and the adjacent floor element, wherein the size and shape of each of said undercut, upper cheek surface, at least one snapping hook and lower cheek surface requires mating by only vertical motion.
- 7. A substantially planar floor element having at least a first edge and a second edge, a lower side and an upper decorative layer, said first edge comprising an undercut and an upper cheek surface at least partially defining a tongue, said second edge comprising at least one snapping hook and a lower cheek surface, wherein a radially projected length (L) of the undercut is less than or equal to a horizontal rotated radially projected height (H) of the upper cheek surface such that when said first edge is mated to a corresponding second edge on an adjacent floor element through substantially vertical motion, said undercut on said floor element unites with the snapping hook on the adjacent floor element and said upper cheek surface unites with the lower cheek surface of the adjacent floor element to prohibit at least vertical separation of the floor element and the adjacent floor element, wherein said undercut has a length smaller than the horizontal height of said upper cheek surface.

9. A substantially planar floor element having at least a first edge and a second edge, a lower side and an upper decorative layer, said first edge comprising an undercut and an upper cheek surface at least partially defining a tongue, said second edge comprising at least one snapping hook and a lower cheek surface, wherein a radially projected length (L) of the undercut is less than or equal to a horizontal rotated radially projected height (H) of the upper cheek surface such that when said first edge is mated to a corresponding second edge on an adjacent floor element through substantially vertical motion, said undercut on said floor element unites with the snapping hook on the adjacent floor element and said upper cheek surface unites with the lower cheek surface of the adjacent floor element to prohibit at least vertical separation of the floor element and the adjacent floor element, wherein said snapping hook has a length smaller than the horizontal height of said lower cheek surface.

10. A method of forming a floor comprising:
- providing a first floor element comprising at least one edge, the edge comprising an undercut and an upper cheek surface;
providing a second floor element comprising at least one edge, the edge comprising at least one snapping hook and a lower cheek surface; and
mating the first floor element with the second floor element by moving the second floor element in a vertical direction with respect to the first floor element, wherein said mating comprises joining the undercut of the first floor element with the snapping hook of the second floor element to limit relative vertical movement between the first floor element and the second floor element, wherein said mating consists of moving the second floor element in a vertical direction with respect to the first floor element. - View Dependent Claims (11)
