Abstract
Floor panels are shown, which are provided with a mechanical locking system on long and short edges allowing installation with vertical snap folding that could be accomplished automatically without tools and where the short edge locking system has a tongue made in one piece with the panel. The floor panels may have a first and a second connector at the long edges that are configured to obtain a minimum of friction facilitating a displacement, by a spring back force from the bending of a short edge locking strip, of a new panel in a horizontal direction along the long edge during the vertical snap folding action.

A set of essentially identical floor panels, each floor panel comprising long and short edges provided with a mechanical locking system comprising first and second connectors integrated with the floor panels, and wherein immediately juxtaposed upper parts of two adjacent joint edges of two joined floor panels together define a vertical plane perpendicular to the main plane of the panels, the first connector comprises a locking strip with an upwardly directed locking element, at a first edge of a floor panel, configured to cooperate with a downwardly open locking groove at an adjacent second edge of another floor panel for connecting the adjacent edges in a horizontal direction perpendicular to the vertical plane, the second connector comprises a tongue, either at the first or at the second edge, extending horizontally perpendicular to the vertical plane, configured to cooperate with a horizontally open tongue groove at the other of said first or second edge for connecting the adjacent edges in a vertical direction parallel to the vertical plane, the connectors at the long edges are configured to be locked with angling and the connectors at the short edge are configured to be locked with vertical snap folding, whereby a long edge of a new panel in a second row is configured to be connected to a long edge of a first panel in a first row by angling, whereby a second short edge of the new panel and a first short edge of a second panel in the second row are configured to be connected with the same angling motion,
- wherein the tongue at one of the short edges is formed in one piece with the panel and protrudes from a substantially vertical upper surface at said one short edge,
- wherein the locking strip at the short edges is bendable, to obtain a resilient bending during the vertical snap folding action, which bending facilitates the assembling of the tongue and the tongue groove, and
- wherein the first and the second connector at the long edges are configured to obtain a minimum of friction facilitating a displacement, by a spring back force from the bending of the short edge locking strip, of the new panel in the horizontal direction along the long edge during the vertical snap folding action.
An installation method to vertically and horizontally connect rectangular floor panels, provided with mechanically locking systems at the long and the short edges, by vertical snap folding at the short edges and angling at the long edges, the method comprising the steps of:
- a) laying a first panel flat on a sub floor
- b) bringing a second panel in an angled position with its long edge in contact with a long edge of the first panel
- c) bringing a long edge of a new panel in an angled position and in contact with an upper part of a long edge of the first panel, whereby the new panel has a higher angle against the sub floor than the second panel,
- d) bringing a short edge of the new panel in contact with a short edge of the second panel,
- e) pressing and displacing the short edge of the new panel downward and horizontally along the long edge towards the short edge of the second panel, and thereby connecting the edges of the first and the second panels to each other in an essentially common plane with a vertical snap folding, and
- f) angling the new and the second panel downward towards the sub floor and thereby finally connecting the first, second and third panel to each other in a common plane with vertical snap folding.
A set of essentially identical floor panels each comprising long and short edges provided with a mechanical locking system comprising first and second connectors integrated with the floor panels, and wherein immediately juxtaposed upper parts of two adjacent joint edges of two joined floor panels together define a vertical plane perpendicular to the main plane of the panels, the first connector comprises a locking strip with an upwardly directed locking element, at a first edge of a floor panel, configured to cooperate with a downwardly open locking groove at an adjacent second edge of another floor panel for connecting the adjacent edges horizontally in a direction perpendicular to the vertical plane, the second connector comprises a tongue, either at the first or the second edge, extending horizontally perpendicular to vertical plane, configured to cooperate with a horizontally open tongue groove, at the other of said first or second edge, for connecting the adjacent edges in vertical direction parallel to the vertical plane, the connectors at the long edges are configured to be locked with angling and the connectors at the short edge are configured to be locked with vertical snap folding,
- wherein the tongue at one of the short edges is formed in one piece with the panel and configured to protrude from a substantially vertical upper surface at the short edge with the tongue, and
- wherein the mechanical locking system at the long edges is configured such that a new panel is displaceable vertically substantially along the vertical plane of a first panel and relative the first panel when the new floor panel is in an angled position in relation to the first floor panel and with the tongue within the tongue groove, and the upper part of the locking element within the locking groove.
