Abstract
A joint for two flat structural members, in particular floor panels, wherein a groove and tongue joint joining two flat structural members is provided functionally separate from a twistlock locking the two flat structural members. The twistlock is formed on one of the structural members, is spaced apart from the groove and tongue joint, and engages with a correspondingly formed engaging element of the other structural member. The locking is preferably formed both at the longitudinal edges and at the front edges of a rectangular structural member, such as a floor panel. The locking allows for a joint of the floor panels to occur in flat position, i.e. without twisting.
Claims23
A joint for plate-shaped structural members, for instance floor panels, comprising a groove and tongue joint passing a parting plane between two adjacent structural members, and a locking for fixing the relative position determined by said groove and tongue joint such that relative movement of the structural members in a direction perpendicular to the parting plane is restricted, the locking comprising a twistlock formed on one of the structural members and separated from said groove and tongue joint, said twistlock being positively or non-positively engageable with an engaging element on the other structural member, said tongue and said twistlock extending substantially the same distance beyond said parting plane.
A joint for plate-shaped structural members, for instance floor panels, comprising a groove and tongue joint passing a parting plane between two adjacent structural members, and a locking for fixing the relative position determined by said groove and tongue joint such that relative movement of the structural members in a direction perpendicular to the parting plane is restricted, the locking comprising a twistlock formed on one of the structural members and separated from said groove and tongue joint, said twistlock being positively or non-positively engageable with an engaging element on the other structural member, said tongue and said twistlock being provided on the same structural member and extending substantially the same distance beyond said parting plane.
A joint for joining adjacent plate-shaped structural members, the joint comprising:
- a tongue provided on a first plate-shaped structural member and extending a distance from a parting plane;
- a groove provided on a second plate-shaped structural member for receiving the tongue;
- a twistlock provided on the first plate-shaped structural member and separated from the tongue by an inwardly extending first recess of variable depth, the twistlock extending a distance from the parting plane substantially the same as the distance the tongue extends from the parting plane, and the twistlock including a notch;
- and
- a second recess provided on the second plate-shaped structural member for receiving the twistlock, an upper surface of the recess having a projection corresponding to the notch of the twistlock such that, when the adjacent plate-shaped structural members are joined, the groove receives the tongue, the second recess receives the twistlock, and the notch receives the projection.
