Definitions

• Laminate flooring and also wooden flooring are often laid in kitchens, hallways and public rooms where they are continually exposed to water, for instance in the form of people walking on the floor with wet shoes and when cleaning the floor with water and the like. In recent years, laminate flooring is being used in bathrooms as well . Laminate and wooden flooring are being sold all over the world and installed in humid climates where the relative humidity may exceed 90%.
• a floor panel comprising a body having a wood fiber-based core, in which floor panel at least two opposite parallel joint edge portions are provided with connecting means for mechanical joining of the floor panel in the horizontal direction with similar floor panels, the connecting means having active locking surfaces for cooperation with corresponding active locking surfaces of adjacent floor panels after the floor panel has been joined therewith.
• the floor panel is distinguished in that at least one of the active locking surfaces wholly or partly is made of an elastically deformable material, other than that of the body of the floor panel .
• the above described manufacturing methods can also be used to produce a mechanical joint system, which contains elastic locking means.
• These elastic locking means can be pressed together as adjoining upper joint edges swell and can expand as they shrink. In this way, the horizontal swelling problems and the arising of visible gaps in a dry floor can be counteracted. Since this swelling problem is mainly related to the long side, the corners are not involved in this respect.
• the elastically deformable material can therefore also be mechanically applied in solid form in the groove for instance by snapping-in or pressing-in into undercut grooves of by gluing to the edge of the groove .
• these elastic locking means will serve as an "elastic compensation seal" .
• Figs la-d illustrate in four steps the manufacture of a floor panel.
• Fig. la shows the three main components surface layer 31, core 30 and balancing layer 32.
• Fig. lb shows a floor element 3, where the surface layer and the balancing layer have been applied to the core.
• Fig. lc shows how floorboards 2 are made by dividing the floor element.
• Fig. Id shows how the floorboard 2 after edge machining obtains its final shape and becomes a completed floor panel 1 with a joint system 7, 7' on the long sides 4a, 4b, which joint system in this case is mechanical.
• the floor panel 1 consists of a direct- laminated surface layer 31, a core 30 of fiberboard-based material (HDF) and a balancing layer 32.
• the vertical locking means which locks the panels 1 and 1' in the Dl direction consists of a tongue groove 9 and a tongue 10.
• the horizontal locking means which locks the panels parallel with the surface layer 31 in the D2 direction consists of a strip 6 having a locking element 8 which cooperates with a locking groove 12.
• the strip is made by machining of the core 30 of the floor panel and is therefore in this embodiment of the invention formed integral- ly with the core 30.
• Dashed arrows MPM indicate how moisture can penetrate from the joint edge into the core 30 as moisture penetrates into the joint system from the front side or upper side of the floor.
• Fig. 6b shows how the impregnating material 24 is positioned in the core 30 of the board element 3 after application of the surface layer 31.
• the impregnating material then constitutes a material seal 20.
• the parting line 45 indicates the intended saw cut.
• a iberboard-based core 30, e.g. HDF, is produced by ground wood fibers being mixed with a binder, such as melamine, after which a panel is formed by means of pressure and heat .
• a binder such as melamine
• the impregnating material 24 can be applied to the panel in connection with this production, the application taking place within special portions which will later constitute joint portions in the floor panel .
• the material seal 20 should, above all because of the expense, be limited to a part of the floor panel 1 where the intended connecting means are formed, and should therefore preferably not cover the entire core surface 33.
• the joint system can have one of more expansion spaces 53a, 53b where the joint seal 55 can swell when being pressed together.
• the joint seal 55 can thus be formed to have some excess, and if the joint system has been formed with appropriate expansion spaces 53a, 55b, the joint seal 55 can be formed with lower tolerance requirements and maintained function.
• the embodiment according to Fig. lie is characterized in that separate materials 58a, 58b, which can constitute a material seal, are arranged above the elastically deformable joints seals 55a, 55b. These separate materials 58a, 58b can also be used for the purpose of decoration by the surface layer 31, for instance, being a beveled portion 60, so that the separate materials 58a, 58b will be visible in the joint. Such a decorative material may also be applied in a grove formed in the core 30 and in the surface layer 31, 32 of the floorboard before the final machining of the edges of the floor panel .
• Figs 15a and 15b show the critical tolerance which lies in the position of the tool 70 when forming, for instance, a groove 41 in the core 30 or the board element relative to the vertical plane VP to be in the floor panel 1' .
• the innermost position of the tool 70 is defined by a plane TP1.
• Fig. 15b shows the outer position of the tool 70 which is defined by a plane TP2 outside the vertical plane VP .
• the contact surfaces of the joint seal 55 for contact with the opposite cooperating joint portion 56 can be formed with great accuracy although the manufacturing tolerance TP1-TP2 for the horizontal positioning of the groove 41 relative to the joint edge to be at the vertical plane VP is fairly great and may exceed 0.2 times the floor thickness T.
• the method is characterized that said fiberboard core 30 is impregnated with at least one property-improving agent within defined band-shaped areas 44 which comprise joint edge portions 86, 87 to be of the floorboards 2.
• the impregnation may take place with an agent improving the elasticity properties of the core 30.
• a floorboard which is intended as semi-manufacture for producing a floor panel 1 and which has a fiberboard core 30 and a surface layer 31 applied to the upper side 33 of the core and which has at least two opposite parallel joint edge portions 86, 87 which are intended for cutting to form connecting means 9, 10 of the floor panel.
• the floorboard is characterized in that the core 30 within at least said joint edge portions 86, 87 is impregnated with a property-improving agent all the way from its upper side 33 and at least a distance down towards the connecting means 9, 10.
• the impregnation may extend up to at least lower parts of the connecting means 6-10, 12, 14, 18.
• the impregnating agent can then be applied both from the surface of the core and from the edges of the groove. Different layers having different properties can also be applied. Rolling or spreading is particularly advantageous in the cases where the impregnating agent contains substances (which are not environment-friendly such as polyurethane (PUR) with isocyanate.
