Floor panel
The invention relates to a floor panel in the form of a multilayer, rectangular laminate with a soft core ( 10 ) of plastic, a décor film ( 12 ) on the upper side of the core ( 10 ), a transparent finishing layer ( 14 ) and a transparent lacquer layer ( 16 ) applied on the finishing layer ( 16 ), as well as a back-pull layer ( 18 ) on the back of the core ( 10 ), with a lockable tongue and groove connection at least at two mutually opposite edges of the panel ( 20, 22 ).
1. Floor panel in the form of a multilayer, rectangular elastic, laminate which deforms, comprising:
a main body including:
a core of elastic, plastic which deforms,
a décor film on an upper side of the core,
a transparent finishing layer on the décor film,
a transparent lacquer layer, applied on the finishing layer,
an elastic, back-pull layer, on a back of the core, and
a lockable tongue and groove connection at least at two mutually opposite edges of the panel,
wherein:
the core is made of a polyvinyl chloride (PVC) material,
the décor film on the upper side of the core is made of a polyvinyl chloride (PVC) material which is printed with a décor,
the back-pull layer simultaneously acts as a sound damping layer, said back-pull layer including sound dampening fillers therein, and
the floor panel has a thickness of 4 to 8 mm.
2. The floor panel of claim 1 , wherein the lacquer layer is UV curable.
3. The floor panel of claim 1 , wherein the panels have a weight per unit area of 1.5 to 2.0 kg per square meter per millimeter of thickness.
4. The floor panel of claim 1 , wherein individual layers of the laminate are bonded to one another by lamination.
5. The floor panel of claim 1 , wherein the fillers include at least one of:
sand, and
chalk.
6. Floor panel in the form of a multilayer, rectangular elastic, laminate which deforms, comprising:
a main body including:
a core of elastic, plastic which deforms,
a décor film on an upper side of the core,
a transparent finishing layer on the décor film,
a transparent lacquer layer, applied on the finishing layer,
an elastic, back-pull layer on a back of the core, and
wherein:
the core is made of a polyvinyl chloride (PVC) material,
the décor film on the upper side of the core is made of a polyvinyl chloride (PVC) material which is printed with a decor,
the back-pull layer simultaneously acts as a sound damping layer, said back-pull layer including sound dampening fillers therein, and
the floor panel has a thickness of 4 to 8 mm, and
a tongue including a head having a greatest dimension measured in a transverse direction of the floor panel, and a connecting portion that connects the tongue to the core of plastic, the connecting portion having a constricted dimension in said transverse direction which is less than said greatest transverse dimension of the head to define a narrow connecting neck; and
a groove for receiving the tongue, the groove having an open end with an inwardly directed protrusion thereat which defines a constricted opening to the groove, with the protrusion engaging the connecting portion when the tongue is inserted fully into the groove, the groove having an expanded head portion for receiving the head of the tongue and which has a greatest dimension measured in said transverse direction, and said constricted opening having a constricted dimension in said transverse direction which is less than said greatest dimension of said expanded head portion; and
the tongue and groove being formed of said core of elastic, plastic which deforms, which permits at least one of the tongue and groove to deform during insertion of the tongue into the groove.
7. The floor panel of claim 6 , wherein said greatest dimension of said head is greater than said constricted dimension of said constricted opening to the groove.
8. The floor panel of claim 6 , wherein the fillers include at least one of:
sand, and
chalk.
