Description
=24590-47 FLOORING PANEL OR WALL PANEL AND USE THEREOF
The present invention relates to a flooring panel or wall panel and the use thereof in a wet room.
During the last few years laminated floors have achieved and increased popularity and on many markets they are beginning to replace parquet floors and wall-to-wall carpets. At the production of laminated floors a decorative thermosetting laminate is first produced. This laminate usually consists of a base layer of paper sheets impregnated with phenol-formaldehyde resin and a decorative surface layer consis-ting of a decor paper sheet impregnated with melamine-formaldehyde resin. The laminate is produced by pressing the different layers at a high pressure and an in-creased temperature.
The laminate obtained is then glued to a carrier of particle board for instance or used as such without any carrier and it is then called compact laminate. The lami-nated panel thus produced is then sawn up to a number of floor boards which are provided with groove and tongue at the long sides and the short sides. Often the floor boards produced have a thickness of about 7 mm, a length of 120 cm and a width of about 20 cm. Thereby they can usually be put on top of an existing floo-ring material at a renovation. According to another alternative, instead one or mo-re of the above decorative sheets can be laminated directly towards a base sheet of particle board for instance.
At the assemblage of such a flooring glue is normally applied in the groove when the floor boards are assembled. Therefore, it will be difficult to change a damaged .board or to remove a whole flooring and for instance install it in another room.
To avoid the above problem efforts have been made to achieve floor boards which can be assembled without glue. One such construction is disclosed in the U.S.
pa-tent 5,295,341. There the boards are provided with groove and tongue in the usual way, but here a snap-together system is included in the groove-tongue joint.
These floor boards can be assembled without glue. However, they have the disad-vantage that the joints between the boards will be flexible and not rigid.
This me-ans that if the surface below the floor boards is not completely even which is usually the case, a gap will be formed between the boards.In these gaps dirt and water can penetrate.
According to the present invention also the last mentioned problem has been sol-ved and a flooring panel or wall panel, preferably of thermosetting laminate having two pairs of parallel side edges has been brought about. Two of these side edges are provided with a locking means in the form of a groove and the other two with a tongue fitting in the groove whereby a tongue/groove joint for assembling of the panels is formed. The groove and the tongue are made of a water tight material and formed with a snap-together joint including one or more snapping webs or the like with corresponding cooperating snapping grooves. The groove in front of the snap-together joint has an entrance opening and continues inside the snap-together joint in a stabilizing groove. The tongue is formed with a rear neck intended to fit in the entrance open[ng and a forwardly protruding stabilizing part situated in front of the snap-together joint and intended for a tight fit in the stabilizing groo-ve, whereby connecting panels when assembled by the snap-together joints and the stabilizing parts in the stabilizing grooves are fixed to each other and prevented from unintentional separation while at the same time a rigid floor covering or wall covering respectively with water tight joints and without unintentional gaps bet-ween the panels is obtained.
According to one preferred embodiment two adjacent side edges of the panel are provided with a groove and the other two side edges with a tongue. At this embo-diment the panel is usually rectangular, but it can also be square.
At square panels it is also possible to provide a pair of parallel sides with a groove and the other pair with a tongue. However, the choice of pattern on the surface layer of the panel is limited at this shape.
It is preferred that the groove and the tongue are made of thermoplast, a thermo-setting laminate, aluminum or a chipboard or particle board impregnated with a thermoplast. Of course also other water tight materials can be used.
At one embodiment, the groove as well as the tongue are formed as a ledge fixed to the side edges of the panel. Suitably the ledge-formed groove and tongue respectively are then fixed in a recess along the side edges with glue for instance.
The snapping webs can be formed on the upper and/or lower side of the tongue while fitting snapping grooves are formed in the groove.
In one preferred embodiment one snapping web is formed on the upper side of the tongue and one on the lower side thereof while the groove has two fitting snap-ping grooves one at the top and one at the bottom.
If necessary one pair of snapping webs can be formed on the upper side of the ton-gue and one pair on the lower side thereof. Of course you then need two snapping grooves at the top and two snapping grooves at the bottom of the groove to fit with the snapping webs.This construction will give an extremely strong joint.
~24590-47 Of course the snapping webs can instead be arranged in the groove and the snap-ping grooves on the tongue.
In one preferred embodiment the width of the stabilizing part is 2-10 mm, prefe-rably 4-10 mm. Generally a wider stabilizing part with fitting stabilizing groove gi-ves a better rigidity of the assembled panels.
The stabilizing part will also assist in a correct assemblage of the panels.
Thus, when the stabilizing part moves into the stabilizing groove you get a correct level of the panels and the panels can easily be pushed into the correct position where you do not have any gap between the panels. Of course without any substantial gap between the panels water and dirt are prevented from entering the assembled flooring or wall covering.
As a safe guard against water penetration a seal might be arranged in the inner part of the stabilizing groove for instance.
Preferably the grooves and the tongues run the full length of the side edges of the panels.
The panels can be designed in such a manner that the under side of the groove and the tongue are situated in the same level as the under side of the panel.
The panels can be used for covering floors and walls in ordinary dry rooms.
However, due to the rigid and water tight joints the panels can be used also for wet rooms. For such applications the whole panel is preferably made of thermoset-ting laminate of so-called compact laminate type. Such a laminate does not absorb water.
Another alternative is a non water absorbing base with a water tight surface.
The surface may for instance consist of paint, a thermoplastic foil such as polyethyle-' ne, polypropylene or polyvinyl chloride, a paper sheet impregnated with thermo-setting resin or of a thermosetting laminate.
One suitable non water absorbing base is a board produced by pressing wood par-ticles or wood chips impregnated with a thermoplastic.

This me-ans that if the surface below the floor boards is not completely even which is usually the case, a gap will be formed between the boards.In these gaps dirt and water can penetrate.
According to the present invention also the last mentioned problem has been sol-ved and a flooring panel or wall panel, preferably of thermosetting laminate having two pairs of parallel side edges has been brought about. Two of these side edges are provided with a locking means in the form of a groove and the other two with a tongue fitting in the groove whereby a tongue/groove joint for assembling of the panels is formed. The groove and the tongue are made of a water tight material and formed with a snap-together joint including one or more snapping webs or the like with corresponding cooperating snapping grooves. The groove in front of the snap-together joint has an entrance opening and continues inside the snap-together joint in a stabilizing groove. The tongue is formed with a rear neck intended to fit in the entrance open[ng and a forwardly protruding stabilizing part situated in front of the snap-together joint and intended for a tight fit in the stabilizing groo-ve, whereby connecting panels when assembled by the snap-together joints and the stabilizing parts in the stabilizing grooves are fixed to each other and prevented from unintentional separation while at the same time a rigid floor covering or wall covering respectively with water tight joints and without unintentional gaps bet-ween the panels is obtained.
According to one preferred embodiment two adjacent side edges of the panel are provided with a groove and the other two side edges with a tongue. At this embo-diment the panel is usually rectangular, but it can also be square.
At square panels it is also possible to provide a pair of parallel sides with a groove and the other pair with a tongue. However, the choice of pattern on the surface layer of the panel is limited at this shape.
It is preferred that the groove and the tongue are made of thermoplast, a thermo-setting laminate, aluminum or a chipboard or particle board impregnated with a thermoplast. Of course also other water tight materials can be used.
At one embodiment, the groove as well as the tongue are formed as a ledge fixed to the side edges of the panel. Suitably the ledge-formed groove and tongue respectively are then fixed in a recess along the side edges with glue for instance.
The snapping webs can be formed on the upper and/or lower side of the tongue while fitting snapping grooves are formed in the groove.
In one preferred embodiment one snapping web is formed on the upper side of the tongue and one on the lower side thereof while the groove has two fitting snap-ping grooves one at the top and one at the bottom.
If necessary one pair of snapping webs can be formed on the upper side of the ton-gue and one pair on the lower side thereof. Of course you then need two snapping grooves at the top and two snapping grooves at the bottom of the groove to fit with the snapping webs.This construction will give an extremely strong joint.
~24590-47 Of course the snapping webs can instead be arranged in the groove and the snap-ping grooves on the tongue.
In one preferred embodiment the width of the stabilizing part is 2-10 mm, prefe-rably 4-10 mm. Generally a wider stabilizing part with fitting stabilizing groove gi-ves a better rigidity of the assembled panels.
The stabilizing part will also assist in a correct assemblage of the panels.
Thus, when the stabilizing part moves into the stabilizing groove you get a correct level of the panels and the panels can easily be pushed into the correct position where you do not have any gap between the panels. Of course without any substantial gap between the panels water and dirt are prevented from entering the assembled flooring or wall covering.
As a safe guard against water penetration a seal might be arranged in the inner part of the stabilizing groove for instance.
Preferably the grooves and the tongues run the full length of the side edges of the panels.
The panels can be designed in such a manner that the under side of the groove and the tongue are situated in the same level as the under side of the panel.
The panels can be used for covering floors and walls in ordinary dry rooms.
However, due to the rigid and water tight joints the panels can be used also for wet rooms. For such applications the whole panel is preferably made of thermoset-ting laminate of so-called compact laminate type. Such a laminate does not absorb water.
Another alternative is a non water absorbing base with a water tight surface.
The surface may for instance consist of paint, a thermoplastic foil such as polyethyle-' ne, polypropylene or polyvinyl chloride, a paper sheet impregnated with thermo-setting resin or of a thermosetting laminate.
One suitable non water absorbing base is a board produced by pressing wood par-ticles or wood chips impregnated with a thermoplastic.
