Abstract

Abstract The invention relates to a system for laying and mechanically joining building panels, especially thin, hard, floating floors. Adjacent joint edges (3, 4) of two panels (1, 2) engage each other to provide a first mechanical connection locking the joint edges (3, 4) in a first direction (D1) perpendicular to the principal plane of the panels. In each joint, there is further provided a strip (6) which is integrated with one joint edge (3) and which projects behind the other joint edge (4). The strip (6) has an upwardly protruding locking element (8) engaging in a locking groove (14) in the rear side (16) of the other joint edge (4) to form a second mechanical connection locking the panels (1, 2) in a second direction (D2) parallel to the principal plane of the panels and at right angles to the joint. Both the first and the second mechanical connection allow mutual displacement of joined panels (1, 2) in the direction of the joint.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 326 words
An edge lock for use in in a flooring system presenting a plurality of floor panels, for mechanically and realisably locking together adjacent edges of pairs of adjacent panels when said adjacent panels are in a state of assembly where they are laying flat on a subfloor with upper corner portions of said adjacent edges being mutually spaced apart, said edge lock comprising: means forming a first mechanical connection for locking said adjacent edges to each other in a vertical direction, and means forming a second mechanical connection for locking said adjacent edges to each other in a horizontal direction at right angles to said edges, including: (i) a locking groove extending parallel to and spaced from an edge of one panel of said adjacent panels and being open at the rear side of said one panel, and (ii) a flexible and resilient locking strip integrated with the other panel of said adjacent panels, said strip extending throughout substantially the entire length of the corresponding edge and being provided with a locking element projecting from the locking strip, wherein said second mechanical connection is so conceived as to operate as an one-way snap lock in said horizontal direction during the assembly of said flooring system by displacing said adjacent edges towards each other, while resiliently urging the flexible locking strip downwards, until upper corner portions of said adjacent edges have been brought into complete engagement with each other and the locking element thereby snaps into the locking groove for preventing drifting apart of said edges, and wherein said first and second mechanical connections are so conceived as to allow said adjacent panels, being mechanically connected to each other by said first and second mechanical connections, to be turned in relation to each other about said upper corner portions of their locked-together edges in an angular direction so as to move the locking element out of the locking groove in order to unlock said one-way snap lock.
Claim 2
Dependent Claim 28 words
An edge lock as claimed in claim 1, wherein said first mechanical connection is a tongue-and-groove connection, including a tongue and a tongue groove for receiving said tongue.
Claim 3
Dependent Claim 42 words
An edge lock as claimed in claim 2, wherein said tongue groove is limited upwardly by an upper lip which is formed in one piece with its corresponding panel and wherein said tongue is made in one piece with its corresponding panel.
Claim 4
Dependent Claim 35 words
An edge lock as claimed in claim 2, wherein said tongue groove is limited downwardly by a lower lip which is formed in one piece with its corresponding panel and which defines said locking strip.
Claim 5
Dependent Claim 20 words
An edge lock as claimed in claim 4, wherein said locking strip presents a thickness variation in its width direction.
Claim 6
Dependent Claim 49 words
An edge lock as claimed claim 2, wherein said adjacent edges being provided with co-operating lower and upper bevels, said lower bevel being formed at a tip of an upper lip which limits said tongue groove upwardly, and said upper bevel being formed in a tip of said tongue.
Claim 7
Dependent Claim 37 words
An edge lock as claimed in claim 2, wherein a tip of said tongue presents a lower surface portion which is non-parallel to an adjacent surface portion of the tongue groove located underneath said lower surface portion.
Claim 8
Dependent Claim 25 words
An edge lock as claimed in claim 1, wherein said locking strip is integrally formed with said other panel, i.e. made in one piece therewith.
Claim 9
Dependent Claim 20 words
An edge lock as claimed in claim 8, wherein said locking strip presents a thickness variation in its width direction.
Claim 10
Dependent Claim 42 words
An edge lock as claimed in claim 1, wherein said flexible and resilient locking strip integrated with said other panel is made of a material different from that of said other panel and fixedly mounted on said other panel at the factory.
Claim 11
Dependent Claim 20 words
An edge lock as claimed in claim 1, wherein said adjacent edges being provided with co-operating lower and upper bevels.
Claim 12
Dependent Claim 23 words
A flooring system as claimed in claim 1, wherein the locking element consists of a locking edge extended continuously along the locking strip.
