Mechanical locking of floor panels with a flexible bristle tongue
Floor panels which are provided with a mechanical locking system including a displaceable tongue in a displacement groove. The tongue is moulded and provided with bendable protrusions. A building panel having an edge portion provided with a groove, in which a tongue formed as a separate part is received, wherein the tongue includes at least two bow shaped protrusions at a first long edge of the tongue, and wherein the protrusions are arranged bendable in the groove.
1. A building panel having an edge portion provided with a groove, in which a tongue formed as a separate part is received,
wherein the tongue comprises a tongue body and a protrusion at an edge of the tongue body,
wherein the protrusion and the tongue body are spaced by a space between the protrusion and the tongue body,
wherein the protrusion is bendable into the space, and in the groove, and
wherein an outer part of the protrusion comprises a round shaped protruding part configured to facilitate installations with vertical folding,
wherein the round shaped protruding part is round shaped in a width direction of the tongue, such that a width of the round shaped protruding part varies along a longitudinal direction of the tongue.
2. The building panel as claimed in claim 1 , wherein the tongue comprises a polymer material.
3. The building panel as claimed in claim 2 , wherein the polymer material is polyamide(nylon), polyoxymethylene, polycarbonate, polypropylene, polyethylene terephthalate, or polyethylene.
4. The building panel as claimed in claim 1 , wherein the round shaped protruding part extends outside the groove.
5. A building panel as claimed in claim 1 , wherein the tongue is of an elongated shape and made of moulded plastic.
6. A building panel having an edge portion provided with a groove, in which a tongue formed as a separate part is received,
wherein the tongue comprises a tongue body and a protrusion at an edge of the tongue body, wherein the tongue body has a length in the longitudinal direction of the tongue,
wherein the protrusion and the tongue body are spaced by a space between the protrusion and the tongue body,
wherein the protrusion is bendable into the space, and in the groove, and
wherein an outer part of the protrusion comprises a round shaped protruding part configured to facilitate installations with vertical folding,
wherein a portion of the round shaped protruding part extends outside the groove,
wherein a length of the portion of the round shaped protruding part extending outside of the groove is less than the length of the tongue body.
7. The building panel as claimed in claim 6 , wherein the tongue comprises a polymer material.
8. The building panel as claimed in claim 7 , wherein the polymer material is polyamide (nylon), polyoxymethylene, polycarbonate, polypropylene, polyethylene terephthalate, or polyethylene.
9. A building panel as claimed in claim 6 , wherein the tongue is of an elongated shape and made of moulded plastic.
