B26D3/06—Grooving involving removal of material from the surface of the work
E04F2203/08—Specially structured or shaped covering, lining or flooring elements not otherwise provided for with a plurality of grooves or slits in the back side, to increase the flexibility or bendability of the elements
Building panels, especially floor panels are shown, which are provided with a locking system comprising several cavities and local protrusions that provide horizontal locking of two adjacent edges.
The disclosure generally relates to the field of mechanical locking systems for floor panels and building panels. The disclosure shows floorboards, locking systems and production methods.
Embodiments of the present disclosure are particularly suitable for use in floating floors, which are formed of floor panels which are joined mechanically with a locking system integrated with the floor panel, i.e. mounted at the factory, are made up of one or more upper layers of wood or wood veneer, decorative laminate, powder based surfaces or decorative plastic material, an intermediate core of wood-fibre-based material or plastic material and preferably a lower balancing layer on the rear side of the core. Floor panels with a surface layer of cork, linoleum, rubber or soft wear layers, for instance needle felt glued to a board, printed and preferably also varnished surface are included. Embodiments of the disclosure may also be used for joining building panels which preferably contain a board material for instance wall panels, ceilings, furniture components and similar.
The following description of known technique, problems of known systems and objects and features of embodiments of the disclosure will, as a non-restrictive example, be aimed above all at floor panels and especially thin floor panels such a luxury vinyl tiles, generally referred to as LVT, with long and shorts edges intended to be mechanically joined to each other on both long and short edges.
The long and short edges are mainly used to simplify the description of embodiments of the disclosure. The panels may be square.
As shown in FIGS. 1a and 1b LVT flooring usually comprise a transparent wear layer 3 which may be coated by a PU lacquer 2, preferably UV cured, a decorative plastic foil 4 and one or several core layers 5 a, 5 b which generally are of different density and hardness. Relevant parts of this known description are also a part of the disclosure.
Thin LVT floors with a thickness of 2-3 mm have traditionally been installed by gluing to the sub floor. Recently LVT floors have been introduced on the market that comprises a mechanical locking system, which allows a floating installation without glue. This facilitates installation and eliminates a lot of work to prepare the sub floor for gluing.
Such LVT floors have generally a thickness of 4-5 mm. This thickness is mainly required in order to form the locking system. The panel itself is strong and flexible and a thickness of about 3 mm would in many applications be sufficient but may not be suitable since it's difficult to form a locking system in such thin floors.
Floating LVT floors of this type have however several disadvantages. They are heavy. The density is for example about 1.6 kg/dm3 compared to about 0.8 kg/dm3 for laminate floors. The temperature sensitivity is more than three times higher than for laminate floors. An LVT floor may move about 2 mm/M when the temperature is changing 20 degrees Celsius.
Such problems related to thickness are also applicable in other high quality floor panels such as wood powder based floors with high density and quality. The additional cost of forming a locking system is considerable since the material content of the whole floor panel has to be increased with 25% or more.
In the following text, the visible surface of the installed floor panel is called “front side”, while the opposite side of the floor panel, facing the sub floor, is called “rear side”. The edge between the front and rear side is called “joint edge”. By “horizontal plane” is meant a plane, which extends parallel to the outer part of the surface layer. Immediately juxtaposed upper parts of two adjacent joint edges of two joined floor panels together define a “vertical plane” perpendicular to the horizontal plane. By “vertical locking” is meant locking parallel to the vertical plane. By “horizontal locking” is meant locking parallel to the horizontal plane.
By “locking systems” are meant co acting connecting elements, which connect the floor panels vertically and/or horizontally. By “strip plane” is meant a horizontal plane positioned at the lowest part of the upper strip body surface. By “groove plane” is meant a horizontal plane positioned at the upper and inner part of a locking groove.
FIGS. 1a and 1b show a LVT floor panel with a locking system that is locked with angling. The horizontal locking is obtained by a locking strip 6 having a strip body 7 and a locking element 8 formed at one panel edge 1 that locks into a locking groove 14 formed in another adjacent panel edge 1′.
The strip body 7 has a strip surface 7 a. A strip plane SP is positioned at the lowest part of the strip surface 7 a. The locking groove 14 has a vertical extension that is needed to house the locking element 8. A groove plane GP is positioned at the upper part of the locking groove 14. The floor panel thickness must be adapted to this required vertical distance between the strip plane SP and the groove plane GP. The thickness of the floor panel may be decreased by 25% and more if it would be possible to use a locking system where the vertical distance between the strip plane SP and the groove plane GP may be reduced or even completely eliminated.
It would be a major advantage if thin panels may be locked with a locking system that do not require deep vertical locking grooves and locking elements that extend vertically from the main strip body. It would also be an advantage if the weight may be decreased and if problems related to temperature changes, especially in installations with floor heating, may be eliminated.
An overall objective of embodiments of the present disclosure are to provide an improved and more cost efficient locking system that may be used in primarily thin floorings and floorings with soft flexible core layers.
A specific objective is to decrease weight of LVT floors and adapt the panel such that it is suitable to be installed in areas, which are subjected to considerable temperature changes. Another specific objective is to provide cost efficient production methods to produce locking systems in especially thin floor panels.

To facilitate understanding, several locking systems in the figures are shown schematically. It should be emphasised that improved or different functions may be achieved using combinations of the embodiments.
All embodiments may be used separately or in combinations. Angles, dimensions, rounded parts, spaces between surfaces etc. are only examples and may be adjusted within the basic principles of the disclosure.
FIG. 2a shows from above an edge section of a first 1 and a second panel 1′ according to one embodiment of the disclosure. Several cavities 20 are formed in the strip body 7 from the strip surface 7 a to the rear side of the panel 1. The cavities extend horizontally to the locking element 8. Cooperating vertically extending protrusions 21 are formed on the second panel 1′ between the locking groove 14 and the tongue 10. The locking element 8, in this embodiment, continues along the joint. The cooperation locking surfaces 42, 43 of the locking element and the locking groove are discontinuous.
FIG. 2b shows a cross section A-A that intersects a cavity 20 and a protrusion 21. The strip plane SP and the groove plane GP are located essentially in the same horizontal plane. The protrusion 21 is formed such that it may be inserted in the cavity 20. The extension of the protrusion in the length direction of the joint is smaller than the corresponding extension of the cavity.
It is preferred that the protrusion is 2-5 mm smaller such that a precise positioning during locking is not required when a first panel in a row is installed.
The locking element 8 is located completely below the strip surface 7 a and the strip plane SP. This makes it possible to decrease the floor thickness since no locking groove 14 is needed that extends above the strip plane SP.
FIG. 2c shows a cross section B-B that intersects a part of the strip 6 where no cavity is formed. This unbroken strip body is connected to the locking element 8.
The adjacent second edge 1′ has no protrusion and no locking groove. The lower part of the edge 23 is essentially flat and extends essentially horizontally.
FIGS. 3a and 3b shows the cross sections B-B and A-A in locked position. FIG. 3c shows locking by angling. The locking system may also be designed such that it may be locked by horizontal and/or vertical snapping where a strip bends backwards or a small tongue 10 is pressed into a tongue groove.
FIG. 4a shows a method to form the cavity 20 with punching. The panel is machined with the surface layer pointing downwards. A punching wheel 30 may be used to form cavities 20 in line with the machining of the locking system when the panel is displaced in relation to rotating cutting tools. The cavities may be formed as an intermediate step, when a part of the locking system is formed, or as a last step when the whole edge is formed—in line or as a separate operation. A rotating cutting tool 31 may be used, preferably after punching, to form small guiding surfaces on the locking element.
FIG. 4b shows a method to form local protrusions 21 with a screw cutter 32 that cuts perpendicularly along the joint. Moving saw blades may also be used.
FIGS. 4c and 4d shows adjacent edges in locked position. FIG. 4d shows that embodiments of the disclosure may be combined with a preferably small locking element 8′ that preferably comprises upper guiding surfaces, and a small locking groove 14′.
FIG. 4c shows that the building panel may comprise a third core layer 5 c, preferably positioned vertically within the strip 7, such that the strip 7 is reinforced. The third layer is in a preferred embodiment positioned at the cooperating surfaces of the locking element 8 and the locking groove 14. Such a layer increases the locking strength and makes it easier to position the locking element 8 into the locking groove 14. The core may comprise several such layers.
FIGS. 5a-5c shows that the horizontal locking according to an embodiment of the disclosure may be combined with a flexible and displaceable tongue 11 that is fixed into a horizontally extending fixation groove 12 and that snaps during vertical folding. The disclosure may be used in combination with all known so called fold down systems that are locked with vertical snapping during folding or a side push action after folding when the panels are laying flat on the sub floor. The separate tongue 11 may be fixed to the first 1 or second panel 1′ edge. FIG. 5d shows a flexible bristle tongue that comprises flexible protrusions 13. The tongue is displaced in the fixation groove 12 during folding. A separate tongue may also be fixed into a groove and may comprise an outer part that is flexible.
FIGS. 6a-6d shows that the principles of embodiments of the disclosure may be combined with a separate strip part 6 that is attached to the panel edge and that comprises cavities 20, 20′. The strip part 6 comprises fixing element 33 and strip legs 34 that may be inserted in grooves or pressed into the plastic core. The strip part 6 may be formed such that it may be connected to the panel edge with essentially a horizontal snapping.
FIGS. 7a and 7b show cavities that are formed such that the locking element 8 is discontinuous along the joint.
Embodiments of the disclosure make it possible to form a strong locking in 3 mm floor panels or even thinner. The floor panel may be formed with an upper lip 24, as shown in FIG. 2c , of about 1 mm, a tongue 10 and a tongue groove 9 of about 1 mm and a strip body of about 1 mm. The locking element 8 and the locking groove 14 need no material and this means that considerable cost savings may be reached by decreasing the panel thickness.
FIGS. 8a-8d shows a fold down locking system suitable for very thin floor panels. A separate and preferably flexible and/or displaceable tongue 11 may be inserted into a fixation groove 12 that is formed such that its lower part is located essentially on the same horizontal plane HP as the upper part of the strip 6. The strip 6 is an extension of the lower part of the fixation groove 12. The lower part 9 a of the tongue groove 9 is in locked position located essentially on the same horizontal plane HP as the upper part of the strip surface 7 a. FIG. 8b shows the second panel 1′ turned upside down with the surface pointing downwards. The separate tongue 11 overlaps vertically an inner part of the cavity 20. An advantage is that the locking system may be formed in a thinner panel since the protrusions 21 are located in the cavities 20 below the upper part of the strip surface 7 a.
FIGS. 9a-9d show a locking system that may be locked with a vertical motion and that comprises a tongue 10 a on the lower part of the protrusion 21. The tongue is in this embodiment formed in one piece with the panel. FIG. 9b show that the locking element 8 comprises a flexing part 22 that bends essentially horizontally and outwardly. The tongue 10 a locks against an undercut 15 formed on the lower part of the cavity 20. It is an advantage if the protrusion 21 is smaller in the length direction of the joint than the corresponding opening of the cavity 20. This facilitates flexing of the flexible part 22 that will be pushed outwardly during locking. The panel may comprise a reinforcement layer 5 c of for example glass fibre or a strong plastic layer that may increase the strength and flexibility of the locking element. The reinforcement layer is preferably unbroken around the whole cavity 20. One or several tongues may be formed on the protrusion at the outer 10 a or inner part 10 c or on one or both edges 10 b, 10 d along the joint.
FIGS. 10a-10f show different embodiments of the locking system shown in FIG. 9. FIG. 10a shows a tongue 10 c formed at an inner part of the protrusion that may comprise a bending groove 16. FIGS. 10b and 10c show two tongues 10 a, 10 c with corresponding undercuts 15, 15 a. FIGS. 10d and 10e show a tongue and groove connection 10,9 formed at an upper edge above the strip and FIG. 10f shows a hook connection that only locks horizontally.
All embodiments shown in this description may be partly or completely combined and may be used optionally on long and/or short edges.
LVT panels are produced in sheets that are cut vertically into several individual floor panels 1,1. The forming of the locking system creates a waste W, as shown in FIG. 11a . FIGS. 11b-11f show that cutting the individual panels vertically and horizontally may reduce the waste W. A cutting groove 36 is preferably formed with knifes, carving tool or rotating cutting tools and various combinations of such tools. The panels are thereafter separated by a knife 35 a that cuts essentially horizontally and a knife or carving tool 35 b that cuts essentially vertically. FIG. 11e shows that the first edge 1 is formed with a lower part 40 that protrudes horizontally beyond the upper part and the second edge 1′ is formed with an upper part 41 that protrudes horizontally beyond the lower part. A non-linear cut with knives or scraping tool may be formed and this may give considerable material savings. FIG. 11f shows that the whole cut may be formed with one knife 35 c that cuts vertically and horizontally.
FIGS. 12a and 12b show forming of the panel edges by a screw cutter 32 that cuts perpendicularly to the displacement direction of the panel 1′ and forms the protrusions 21.
A locking system in a plastic based LVT flooring may be formed with traditional rotating cutting tools that cut as a saw blade but also partly or completely with cutting knives that may be fixed or rotating. Carving tools may also be used. FIGS. 13a-13d show that all parts of a mechanical locking system may be formed by cutting knifes which have a straight cutting edge 35 a, 35 b, 35 c or which have an irregular form 35 d, 35 e, 35 f and 35 g. Cutting knives with a straight edge are preferably rotating knives. The irregular knives are preferably formed as open V or U-shaped section that allow the cut-off material to flow in the inner part of the cutting tool 37 such that it may be removed when the tool 35 or the panel 1 is displaced in relation to each other.
The knives may be stationary and the panel may be displaced in relation to the knives. It is also possible to displace the knives in relation to a fixed panel.
Increased temperature will facilitate all type of separation and forming of the edges with for example knives, carving, punching wheels, screw cutters etc. since plastic material is considerable softer when the temperature is increased. The panel may be heated completely or only locally with for example infrared lamps, hot air etc. that heat an edge part.
Bevels or rounded edges are easily formed at increased temperature and with rollers or pressing wheels that compress and form the edges. Such forming devices may be embossed and the edges may be formed with the same structure as the panel surface. A decorative paint may be applied during forming.
Parts of the locking system may also be formed with heat and rollers that press and form the edge.
LVT floors are very moisture stable but they expand or shrink when the temperature is changing. Some LVT floors may shrink and expand about 2 mm when the temperature is changing from 10 to 40 degrees Celsius. This may cause problems when LVT floors are installed floating especially in a room with floor heating.
The major reason for the temperature sensitivity is the type of plastic (PVC) that is used in the surface and core layers. Adding special fillers into the core layers may decrease the temperature sensitivity.
The expansion and shrinking may be compensated by the flexibility of the panel. This flexibility must be such that the locking system is able to keep the floor together in low temperature and such that the panels will not warp or bend upwards when they expand in high temperature.
FIGS. 14a, 14b and 14d show that the flexibility may be increased considerably if several flexing grooves 19 are formed at the rear side of the core 5 b. Such grooves may preferably be formed with knives along and/or across the board. The cut-off material may be recycled completely and used to produce a new core. The grooves may also be formed when the panel is pressed. Such a production method is suitable when the sheets are pressed in a discontinuous press. Knives may preferably be used when the sheets are produced in continuous presses. The material is very easy to remove when the material is hot.
FIG. 14b,d show that the flexing grooves may be covered with an underlay 18 that may be foam or any other plastic material similar to the material used in the core. It is preferred that the flexing grooves 19 have a vertical extension of at least about one third of the core thickness.
The grooves 19 may be used to decrease the weight of the panel.
FIG. 14c show that including layers that are more stable, for example one or several layers of glass fibre or a sub core 17 that preferably comprises wood fibres, may increase the temperature stability. The sub core 17 may be a high quality HDF board or wood powder based board with high moisture resistance.
FIG. 15a-d show a locking system that is locked with vertical snapping. The protrusion 21 comprises a tongue 10 a that cooperates with an undercut 15 a formed at the rear side of the locking element. The tongue 10 may be formed at an inner part of the protrusion 21. The protrusion 21 and the locking element are bent and displaced horizontally during the vertical motion, as shown in FIGS. 15b and 15c . FIG. 15d shows a cross section where no protrusion and cavity are formed. Such cross section has only a horizontal locking. This embodiment is characterized in that the locking system comprises a first set of sections along the joint that locks only horizontally and a second set of sections that locks horizontally and vertically. The locking system is also characterized in that the protrusion 21 and the locking element 8 are displaced horizontally during the vertical motion.
FIGS. 16a-16d shows a locking system similar to the system shown in FIGS. 15a-d . The tongue 10 a is however formed at an outer part of the protrusion 21. The locking element 8 may also be discontinuous as shown in FIGS. 16c-d . Such geometry facilitates the forming of the cavities 20 that may be formed with rotation tools. This embodiment is characterized in that the locking system comprises a first set of sections along the joint (A-A) that locks only vertically and a second set of sections (B-B) that only locks horizontally.
FIGS. 17a-c shows the locking of the locking system according to FIGS. 16a-d . A first set of sections A and the second set of sections B are displaced vertically wherein the protrusion 21 is displaced horizontally and inwardly during locking.
FIGS. 18a-c shows a locking system where the cavities 21 and protrusions 20 are mainly used to guide the floor panels during the angling action. The horizontal locking is accomplished with cooperating locking surfaces 42,43 on the locking element 8 and the locking groove 14 that are located above and below the strip plane SP. A strong locking may be obtained in plastic material with vertically extending locking surfaces that are only about 0.2-0.5 mm, especially if the locking angle 44 on a part of the locking surfaces is high, for example about 90 degrees as shown in FIG. 18b . The locking is only possible if a protrusion is positioned above a cavity. The locking may be accomplished in several steps. In case the protrusion 21 is not above the cavity 20 as shown in FIG. 18c , the panels will stay in an angled position. A displacement along the joint may thereafter take place and the protrusion 21 will automatically fall into the cavity 20 as shown in FIG. 18c . FIG. 18d shows that the tongue 10 may be formed on the edge comprising a cavity 20. This embodiment may be used to save material.
FIG. 19 shows that flexing grooves 19 may be formed at the rear side with a length that is smaller than the length of the rear side. Such forming may be made with rotating jumping tools or with knives. The advantage is that the flexing grooves 19 are not formed in the edge sections where the locking system is formed. The flexing grooves 19 may be essentially parallel with the long edges and may have a length that is smaller than the distance between the locking systems on the short edges.
FIG. 20a-b show that position marks 45 may be formed by mechanical forming or with colour spots on the tongue 10 such that they are visible from the front side. They may be used to position the protrusions 21 above the cavities 20. FIG. 20b shows that the flexing grooves 19 may be discontinues and arranged in various patterns.
FIG. 21a-d show that resilient floors may be delivered in rolls with overlapping short edges where each roll corresponds to one row. The rolls have preferably a width of 0.1-0.5 m and may comprise floor material that in installed position has a length of several meters. A preferred embodiment is a roll comprising a resilient flooring material, preferably PVC material, which in an unrolled and installed position has a length that is larger than 15 times the width. An even more preferred embodiment is a roll with an installed length that is larger than about 50 times the width. Such a roll may be about 0.2 m wide and about 10 m long and may comprise 2 m2 of flooring material. An extruded locking strip 46 comprising a first 47 and second 48 upwardly extending protrusions may be attached in a holding groove 49 in one edge of the roll. The first upwardly extending protrusion 47 is attached in a holding groove 49 of a first edge 1 and the second upwardly extending protrusion 48 is rolled and pressed during installation into a locking groove 14 formed in the adjacent edge 1′ of a second roll. Such a combined pressing and rolling action facilitates the insertion of the protrusion 48 into the locking groove 14 since the protrusion is gradually inserted into the locking groove when the floor is unrolled.
FIGS. 22a-22d shows that all the above described embodiments may be used to form locking strips 46 a, 46 b that may be attached on adjacent panel edges or roll edges as separate strips in order to provide a vertical and/or horizontal locking. FIGS. 22b and 22c shows that punching of an extruded plastic section may form locking strips comprising cavities 20 and protrusions 21. FIG. 22d shows the locking strips in a locked position. The locking system is locked by vertical displacement where the protrusions 21 are inserted into the cavities 20 with a rolling motion. The first upwardly extending protrusion 47 may be combined or replaced by glue or thermal bonding. The locking strips may comprise several upwardly extending protrusions 48′, 48 as shown in FIG. 22 d.
The methods above may also be used to lock linoleum floors and other resilient floors.
