A construction and methods of assembly and construction of boards, e.g. floor boards, are described. The boards have a peripheral connection arrangement for interconnecting of one board to another, a core layer e.g. made from a wood or fiber based material and a top layer applied to the core layer which may be decorative and may include or provide a wear layer. A further bottom layer may be applied to the underside of the core layer and is designed to be in contact with the floor or an underlay can be applied when in use. The connection arrangement includes interconnecting hooking tongues and corresponding catches which co-operate to produce both vertical and horizontal locking.

Floor panels are shown, which are provided with a mechanical locking system that may be locked with a vertical displacement of a first panel against a second panel. The locking system includes a flexible strip that during locking bends upwardly or downwardly. The locking system includes a first and a second joint edge section with different locking functions. One section provides a horizontal locking and another section provides a vertical locking.

The system for removably securing slats juxtaposed to form a deck, for example for a terrace, includes fasteners disposed in rows on level floor or joist or beam structure supports oriented perpendicular to the axis of the slats. The fasteners have a device for securing the supports to the slats. A plurality of impermeable channels is disposed parallel for a level floor, or at a rate of one impermeable channel for each joist or beam support. The top surface of the support, a device for removable securing and a device for positioning provided on the profiled section are covered. The fasteners are made of a flexible elastic material, and the device for positioning allows clearance in a direction of an axis of the channel.

A panel including a centrally located core, at least one first coupling part and at least one second coupling part connected respectively to opposite edges of the core, which first coupling part includes 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 a second coupling part of an adjacent panel: which second coupling part includes 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 an upward tongue of a first coupling part of an adjacent panel.

A flooring system including floor panels and a connecting system for connecting the floor panels is provided. The flooring system includes a first and a second floor panel, and a connecting device that includes a first and a second connecting element. The first connecting element is configured to cooperate with the first and second floor panel for horizontally connecting the first and second floor panel. The second connecting element is configured to cooperate with the first connecting element for vertically connecting the first and the second floor panel. A connecting device for connecting a first and a second floor panel is also provided.

A set (1) of tiles (5) adapted to cover a surface (10) perpendicular to a thickness direction (V) of the tiles (5), each of the tiles comprising at least one upper layer (24), and an underlying rigid core layer (22), the core layer and the upper layer being superimposed in the thickness direction, and the core layer defining a lower surface (S) opposite the upper layer. The tiles comprise at least one first tile (15) having a first edge extending in a longitudinal direction (L), the core layer of the first tile (15) defining a connecting groove (28) in the first edge. The tiles comprise at least one second tile (20) having a second edge extending in the longitudinal direction, the core layer of the second tile defining a connecting tongue (34) protruding from the second edge, the connecting tongue being adapted to be snap-fit into the connecting groove in a connecting direction (C) perpendicular to the longitudinal direction (L) and to the thickness direction in a locked configuration of the first tile and the second tile. The lower surface defines an additional groove (30) parallel to the first edge.

A flooring system is provided comprising a plurality of (identical) floor panels, which are mechanically connectable to each other along at least one pair of adjacent first and second opposite joint edges. The panels comprise locking elements for connecting said panels in both horizontal and vertical direction. In order to consider the often occurring situation that in panels—especially when stored under changing external conditions, especially changing humidity—might warp, the (vertical) locking element in the panels is constructed with a (slight) play, so that in the event that two panels have slightly different warp nevertheless can easily and reliably be mechanically connected with each other omitting the need to exert an excess of force to fit the panels.

A panel (1) having the shape of a plank or a tile for the production of a floor covering, the panel (1) comprising two pairs of opposed sides defining: two opposed edges for inclined assembly (2), wherein one edge comprises male coupling means (4) provided from a lateral wall of the panel (1), and an opposed edge comprising complementary female coupling means (5) provided from a lateral wall of the panel (1); two opposed edges for vertical assembly (3), wherein one edge comprises male coupling means (6) provided from a lower face of the panel (1), and an opposed edge comprising complementary female coupling means (7) provided from an upper face of the panel (1);
characterized in that: the male coupling means (6) of the edges for vertical assembly (3) comprise a male groove (6a) extending along the edge and opening onto the lower face of the panel (1) in a manner such as to define a male tenon (6b), the male tenon (6b) having an outer wall (6c) which is inclined with respect to a vertical plane and towards the outside of the panel (1); the female coupling means (7) of the edges for vertical assembly (3) comprise a female groove (7a) extending along the edge and opening onto the upper face of the panel (1) in a manner such as to define a female tenon (7b); the male coupling means (6) of the edges for vertical assembly (3) comprise a lug (10) or a notch (11) and the female coupling means (7) of the edges for vertical assembly (3) comprise a complementary notch (11) or lug (10) which, after assembly of two adjacent panels (1), form abutment stops to counteract a vertical displacement between two adjacent assembled panels (1).

A joint for floors that are provided by way of a series of strips, constituted by a single linear bar which is constituted by a central planar body from which a first tab and a second tab, which are elastically deformable, protrude laterally.

The first tab and the second tab are selectively associable at adapted seats provided in a lower region and longitudinally with respect to the strips and adjacent to the longitudinal perimetric edges thereof.

Each one of the first tab and the second tab has a first portion, substantially arc-shaped, meant for blending with the planar body, which protrudes toward the outside of the planar body, a second portion, contiguous and blended with the respective first portion, protruding and directed toward the inside of the planar body, and a third portion, contiguous and blended with the second portion, which protrudes toward the outside of the planar body.

A panel having a substrate and a top layer provided thereon, wherein the top layer comprises at least a melamine resin and a binder, the binder being selected from the group comprising: polyacrylates based binder, polyvinyl acetate based binder, polyester based binder, acrylic copolymers based binder or urethane based binder.
