A snap-fit connection arrangement includes groove and tongue strips respectively having a groove and tongue, and first and second attachment regions for placement along first and second components, respectively. The groove and tongue strips respectively extend in first and second longitudinal directions transversely to their respective cross sections. Cross-sectional contours of the tongue and the groove correspond to each other through use of latching elements so that a snap-fit connection can be established as the tongue is inserted in a joining direction into the groove. The snap-fit connection allows for relative movement between the tongue and groove strips along at least one of the longitudinal directions and prevents relative movement between the tongue and groove strips transversely to at least one of the longitudinal directions. The tongue includes a latching recess comprising an undercut that extends along and within the tongue and is configured for latching engagement with a rib.

A set including a first panel, a second panel and a mechanical locking device for locking the first panel to the second panel, the mechanical locking device includes an insertion groove at the second edge surface, a flexible tongue positioned in the insertion groove and an edge tongue including a tongue groove, the flexible tongue includes a first locking surface and a second locking surface, the first locking surface is configured to cooperate with the tongue groove for locking of the first panel to the second panel in a first direction when the flexible tongue is positioned in the insertion groove in a first orientation, the second locking surface of the flexible tongue is configured to cooperate with the tongue groove for a locking of the first panel to the second panel in a first direction when the flexible tongue is positioned in the insertion groove in a second orientation.

A vertical joint system for substrates is formed with joints and which engaged by relative motion in a direction perpendicular to major surfaces and of the substrate. The joints are configured to enable relative rotation of up to 3 degrees while maintaining engagement of the joints. The joints and are further configured to form two locking planes one on each of the inner and outer most sides of the joint. Engagement about the locking planes is provided by transverse outward extending surfaces. At least one surface in each pair of engaging surfaces is smoothly curved. The joints and can be further arranged to provide a third locking plane parallel to and between the locking planes. The joints are disengaged by combination of a downward rotation of one joint relative the other then application of a downward force.

A joint filling profile for forming a joint sealing between floor slabs includes a vertical leg projecting into the joint and a profile body formed from a joint sealing compound and located in a joint widening. The vertical leg and the profile body are separated from each other with the interposition of a first separating material, wherein at least one second separating material is arranged between the vertical leg and the profile body and/or at least one reinforcing mat is arranged within the profile body. The second separating material and/or the reinforcing mat are arranged in such a way that they overlap with the first separating material at least in regions.

A panel includes a top side, a bottom side and a first edge extending between the top and bottom side and having a first coupling part; and a second edge extending between the top and bottom side and having a second coupling part. The coupling parts make it possible to produce a horizontal and vertical lock between two such panels by means of a vertical movement of the one panel with respect to the other panel.

Snap-type movable wooden floor and its assembling method thereof. The present invention relates to the technical field of decoration. The connecting buckle is arranged in a “mountain”-shaped structure, and the groove surfaces on the left and right sides are both obtuse inclined surfaces, and the inner sides of the left and right ends of the connecting buckle, both sides are provided with a clamping arc surface arranged from bottom to top from the inside to the outside; both sides of the above-mentioned floor board are provided with clamping grooves which are mutually clamped with the upper ends of the connecting buckles arranged in, as previously mentioned, “mountain”-shaped structure. The connecting buckle under the card slot constitutes an obtuse-angled clamping end that is engaged with the groove with an obtuse-angled bevel.

A flooring element suitable for connection to other elements in a flooring system. The flooring element comprises a body, a female connector and a retainer. The body defines a connector surface that is horizontal when in use. The female connector comprises a connector recess which is suitable for receiving a male connector and also which defines a connector opening in the connector surface. The retainer is connectable to the body such that, while it is connected to the body, the retainer is movable between and open position and a closed position. When in the closed position, the retainer is arranged to restrict movement of the male connector to guard against the male connector exiting the connector recess through the connector opening. When in the open position, the retainer does not restrict movement of the male connector thereby permitting the male connector to exit the connector recess through the connector opening.

The joints are configured to enable relative rotation of up to 3 degrees while maintaining engagement of the joints. The joints and are further configured to form two locking planes one on each of the inner and outer most sides of the joint. Engagement about the locking planes is provided by transverse outward extending surfaces. At least one surface in each pair of engaging surfaces is smoothly curved. The joints and can be further arranged to provide a third locking plane parallel to and between the locking planes. The joints are disengaged by combination of a downward rotation of one joint relative the other then application of a downward force.
