Description

{MECHANICAL LOCKING SYSTEM FOR FLOOR PANELS}

Technical field

The present disclosure relates generally to the field of mechanical locking systems for floor panels and building panels. The present disclosure shows floor boards, locking systems, mounting methods and manufacturing methods.

Application Field of the Invention

Embodiments of the present invention are particularly suitable for use in floating floors formed of floor panels, which are mechanically connected by a locking system integral with the floor panel, i.e. factory mounted, One or more upper layers of a wood veneer, decorative laminate, powder-based surfaces or decorative plastic material, an intermediate core of a wood-fiber-based material or plastic material and preferably a back side And a lower balancing layer on the lower layer. Surface layers or soft wear layers of cork, rylloid, rubber, for example needle felt bonded to boards, printed and preferably also varnished surfaces and such as stones, tiles and similar materials Floor panels with floors with hard surfaces are included. Embodiments of the present invention may also be used to connect building panels that preferably include board materials, such as wall panels, ceilings, furniture components, and the like.

Accordingly, the known techniques, problems of known systems, and the following description of the objects and features of the present invention, as a non-limiting example, are to be accorded the broadest interpretation of the invention, The aim is panels formed as rectangular floor panels with intended long and short edges.

Long and short edges are mainly used to simplify the description of embodiments of the present invention. The panels may be square. Embodiments of the present invention are preferably used for short edges. Embodiments of the present invention may be combined with any known type of locking system that may be used on any floor panel and formed on long edges, wherein the floor panels are horizontally and vertically on two or more adjacent sides It should be emphasized that it is intended to be connected using mechanical load balancing systems connecting the panels.

BACKGROUND OF THE INVENTION

Laminate flooring typically comprises a core of 6 to 12 mm fiberboard, a top decorative surface layer of plywood of 0.2 to 0.8 mm thickness, and a bottom balancing layer of plywood, plastic, paper or similar material of 0.1 to 0.6 mm thickness . The plywood surface includes melamine-impregnated paper. The most common core materials are fiber boards with high density and excellent stability, commonly referred to as HDF-high density fiber boards. Sometimes also MDF-medium density fiber boards are used as cores.

Conventional plywood floor panels of this type were connected by glued tongue-and-groove joints. In addition to these conventional floors, floor panels have been developed which do not require the use of adhesives but which are mechanically connected by so-called mechanical locking systems. These systems include locking means for locking the panels horizontally and vertically. Mechanical lock systems are usually formed by machining the core of the panel. Alternatively, portions of the locking system integral with the floor panel, i. E., Associated with the floor panel in connection with the manufacture of the floor panel, may be formed of separate materials, such as aluminum or HDF.

The main advantages of floating floors with mechanical locking systems are that these floating floors are easy to install. These floating floors can also easily be taken up again and used again at another location.

Definition of some terms

In the following, the visible surface of the installed floor panel is referred to as the "front side" whereas the opposite side of the floor panel facing the lower floor is referred to as the "rear side ". The edge between the front side and the back side is called the "joint edge "."Horizontalplane" means a plane extending parallel to the outer portion of the surface layer. The directly juxtaposed portions of two adjacent joint edges of two connected floor panels together define a "vertical plane" perpendicular to the horizontal plane. "Inner vertical tongue plane" means a plane parallel to the vertical plane where the outer and innermost portions of the main tongue-shaped body intersect. "Vertical lock" means a lock parallel to the vertical plane. "Horizontal lock" means a lock parallel to the horizontal plane.

&Quot; Upward "means facing the front side," down "means facing the rear side," inward "means facing the inside and center portion of the panel in the horizontal direction, "Outwardly" means mainly moving in the horizontal direction from the central portion of the panel.

"Locking systems" means co-acting connection elements that connect floor panels in a vertical direction and / or a horizontal direction.

Related technology and its problems

Several methods for mechanical connection of short edges as well as long edges in the first horizontal and vertical directions perpendicular to the long and short edges can be used. One of the most commonly used methods is the slope-snap connection method (angle-snap method). Long edges are installed by angling. The panel is then displaced into the locking position along the long side. Short edges are locked by a horizontal snap connection. The vertical connection portion is generally a tongue portion and a groove. During horizontal displacement, the strip with the locking elements bends and when the edges contact, the strips spring back and the locking element enters the locking grooves to lock the panels in the horizontal direction. This snap connection is complicated because the hammer and tapping block usually need to be used to overcome the friction between the long edges and to bend the strip during the snap connection operation.

Similar locking systems can also be fabricated with rigid strips, which are connected by an angle ring-angle ring method in which both short and long edges are tilted into the locking position.

Recent new and very effective locking systems have been introduced, with separate flexible or displaceable integral tongues on a short edge, which is generally referred to as "vertical folding " Such systems are described in WO 03/083234 and WO 2006/043893 (Vaelinge Innovation AB).

Several versions are available on the market. 1A-1C show displaceable tongues (Fig. 1A) which are displaced inwardly into the displacement groove 21 and outwardly into the tongue groove 20 when the edges of the adjacent panels 1, 1 ' 30). ≪ / RTI > Such systems are referred to as vertical snap systems and these systems are automatically locked during folding operations. The displaceable tongue 30 locks the panels parallel in a direction perpendicular to the vertical plane VP perpendicular to the main horizontal plane of the planes. A locking strip 6 with locking elements 8 cooperating with the locking grooves 14 in the adjacent panel 1 'locks the edges parallel to the horizontal in the main horizontal plane HP.

Figs. 2A to 2E show a so-called bristle tongue formed integrally with one of the most commonly used flexible tongues 30. Such a displaceable tongue 30 is designed to provide a tough and rather stiffness that provides the necessary flexibility and friction connections 36 to prevent the tongue from falling out of the displacement groove 21 during the transportation and installation of the floor panels Of the main body (31), which are flexible protrusions (38) of the main body (31). The bristles are made of high quality plastic materials reinforced with glass fibers. The flexibility should be substantial and allow the flexural deformation to be displaced about 1-2 mm in two directions during locking. The tongues are injection molded and formed into tongue blanks (50) which can include up to 32 tongues. The tongues are connected to the rails 51 which are used to feed tongues during manufacture when the tongues are detached from the tongue-shaped blank and inserted into the edge of the panel.

Although such locking systems and integral bristle tongues provide a very efficient, robust and reliable lock, there is still room for improvement.

One disadvantage is that the entire tongue-in-blank 50 is made of high quality plastic material, which costs considerably. Such a high quality material is required only in those portions of the tongue that form the flexible protrusions 36. High quality plastics material reinforced by glass fibers is not required in the portions of the tongue-like portion that include the main tongue-shaped body 31 and the rails 51. About 60% of the tongue-shaped blanks are made of a material having a higher quality than that required for its particular function.

The second drawback is that each tongue blank 50 requires a wide range of expensive injection tongues for each width.

A third disadvantage is that plastic materials reinforced with glass fibers are difficult to regenerate and scrap from the rails has a very low material value.

It will be a major advantage if the trolleys can be manufactured in a more cost effective manner with respect to material costs and different tongue lengths.

It is known from the above mentioned publications that displaceable tongue parts can be formed from sheet molding materials such as HDF. This can increase material costs by about 80% compared to expensive plastic materials. The flexibility can be obtained by a flexible rubber strip which is inserted into the inner part of the displacement groove or attached to the inner part of the extruded plastic section. Such a two-piece tongue would not provide sufficient strength and flexibility because compression occurs outside the displaceable tongue between the inner portion of the displacement groove and the inner edge of the tongue-shaped body. The grooves must be considerably deep and this will adversely affect joint stability. The manner in which the flexible material is attached to the tongues in the tongue-like blank and how the tongue-like portion is formed to allow the tongue-like portion to slide in the groove without the risk of being pulled out of the groove after manufacture. The cost of the flexible material is still quite high because the flexible portion extends along the entire tongue length.

It is a general object of embodiments of the present invention to provide long and short edges that are installed in parallel rows that allow short edges to be automatically locked together by vertical snap action caused by the tongues that are displaced in the grooves It is an object of the present invention to provide an improved and more cost effective locking system for primarily rectangular floor panels. More particularly, the object is to provide a locking system having separate displaceable tongues formed of different materials so that cost and function can be optimized.

Another specific object is to provide a tongue which can be manufactured in different lengths without the requirement of individual injection-molding tools specifically designed for each tongue length.

The above objects of an embodiment of the present invention may be achieved in whole or in part by the locking systems and floor panels according to the disclosure. Embodiments of the present invention are apparent from the description and drawings.

A first aspect of the present invention are building panels provided with a locking system for vertical locking of first and second building panels by vertical displacement of the panels relative to each other. The displaceable tongue is attached into the laterally open displacement groove provided in the edge of the first panel. The tongue cooperates with a tongue groove provided in an adjacent edge of a second panel for locking the edge vertically. The strips protrude outward beyond the upper portion of the edge and below the displacement groove or beneath the tongue groove and beyond the upper portion of the adjacent edge. The displaceable tongue portion includes a main tongue-shaped body extending along an edge of the first panel and a separate flexible spring portion attached to the main tongue-shaped body. A separate spring portion is located in the inner portion of the displacement groove.

The tongue-like portion may include two or three or more spring portions spaced from each other in the longitudinal direction of the main tongue-shaped body.

The spring portions may be asymmetrical in the direction along the edge.

The main tongue body and spring portions can be made of different materials.

The tongue-like portion includes a fixed groove opened upwardly or downwardly.

The spring portions may include fixed connection portions extending upwardly or downwardly.

The spring portion can be displaced or compressed in the horizontal direction beyond the vertical tongue plane including the inner portion of the tongue-shaped body during locking.

The spring portion may overlap with a portion or tongue-shaped body during locking.

The spring portion may be located in a vertically open flexing cavity formed in the tongue-shaped body.

The building panels are preferably floor panels.

A second aspect of the invention is a tongue-like blank comprising two or more tongues that are each adapted to be inserted into a groove of a building panel to lock the building panel to an adjacent building panel. A portion of the tongue-like portion is configured to be displaced during locking. The tongue-like portions are elongate in shape and each tongue-like portion includes a separate spring portion connected to the main body of the tongue-like portion.

The separate spring portions may be asymmetrical in the longitudinal direction of the tongue-like portion.

Each of the tongues may include two or three or more spring portions spaced apart from one another in the lengthwise direction of the tongue.

All embodiments may be used individually or in combination. Angles, dimensions, rounded portions, spaces between surfaces, etc. are exemplary only and can be adjusted within the basic principles of the present invention.

Figures 3A-3G illustrate a first preferred embodiment of a displaceable tongue-like portion 30 that is intended to be used to lock two adjacent edges of two floor panels by vertical displacement of the panels relative to each other.

Figure 3a shows a tongue-like body (31) having a main tongue-shaped body (31), a longitudinal direction (L) along the joint, a transverse tongue 30). The inner vertical tongue plane (Tp1) and the outer vertical tongue plane (Tp2) parallel to the longitudinal direction of the tongue-like portion intersect the outer edges of the tongue-like portion.

3B shows a displaceable tongue 30 comprising a separate spring portion 40 attached to the main tongue-shaped body 31. The spring portion includes a friction portion 36 formed as a small local projection extending vertically from the spring portion body 41, preferably a spring portion body 41, and a fixed groove (not shown) formed in the main portion body 31 32). ≪ / RTI >

Figure 3c shows a spring portion blank 60 viewed from above with several spring portions 40 connected to each other and to spring portion rails 61 in parallel rows.

Figure 3d shows the spring part blank viewed from below. Each spring portion 40 is formed as a protrusion extending from the main spring portion body 41 in this embodiment to the extension of the friction connection 36 in the vertical and opposite directions.

Figure 3e shows the main tongue-shaped body 31 formed in this embodiment as a two-dimensional profile with the same cross-section along the tongue-shaped body. Such a tongue-shaped body can be formed, for example, by linear machining, extrusion or by injection molding in which fairly simple forming tools are used.

Figure 3f shows a tongue which can be displaced in an external locking position and which is spaced from each other in the longitudinal direction of the main tongue body 31 and the tongue 30 and which is mechanically connected to the tongue body 31 ≪ / RTI > include separate spring portions 40, 40 '.

Figure 3g shows the displaceable tongue in the inner unlocked position when the tongue 30 is pressed into the laterally open displacement groove 21. The spring portion is displaced inwardly beyond the first vertical tongue-like plane Tp1 but is also displaced over a portion of the main tongue-shaped body 31. The thickness of the spring portion is smaller than the thickness of the tongue-shaped body 31. This embodiment is advantageous because the spring portion can be easily connected to the tongue-shaped body having a fairly simple cross-section and the main tongue-shaped body 31 and spring body body 41 can overlap each other at the locking and unlocking positions, Can be reduced.

Any type of polymeric material can be used to form the spring portions, such as PA (nylon), POM, PC, PP, PET or PE, or similar with similar properties as described above in different embodiments. Such plastic materials can be reinforced, for example, with glass fibers, Kevlar fibers, carbon fibers or talc or chalk when injection molding is used. Preferred materials are glass fibers, particularly long, reinforced PP or POM. Such materials can also be used to form the main tongue-shaped body.

The tongue-shaped body preferably comprises a low-cost material that can be machined. Suitable materials are wood fiber based materials that are combined with thermoplastic or thermosetting binders.

Figure 4a shows a portion of a displaceable tongue 30 comprising a spring portion 40 connected to the upper portion of the main tongue-shaped body 31. 4b shows a spring portion 40 having a fixed connection portion 42 that is flexible and configured to be vertically connected into a vertically open fixed groove 32 formed on the upper portion of the tongue-shaped body 31 It is shown from below. The fixed connection portion 42 includes a horizontal friction projection 43 that is pressed against the vertical wall of the fixed groove 32.

AA shows the transverse section of the middle portion of the main tongue-shaped body. BB shows the cross section of the outer portion of the main tongue body. The figures show that a portion of the spring body 41 is located above the upper portion of the tongue-shaped body 31 and the first vertical tongue-like portion plane Tp1 during locking such that a portion of the spring- Lt; / RTI >

5A shows a cross-section of a tongue-shaped blank 50 comprising a number of displaceable tongues, including a main tongue-shaped body 31 and separate flexible portions 40 connected to the main tongue-shaped body. Figure 5b shows a tongue-shaped body blank 70 comprising several tongue-shaped body bodies 31 connected with tongue-shaped body rails 71. Such rails may be formed, for example, by perforating the material from the tongue-shaped bodies. Figure 5f shows spring portion blank 60 where spring portions are essentially positioned at the same distance D between the tongue-shaped body 31 and each other. 5g, which is parallel to the tongue-shaped bodies on the tongue-shaped bodies, can be displaced and the fixed connection portion 42 is pressed in the vertical direction to enter the fixed groove 32 , Which facilitates fastening of the spring portions to the tongue-shaped bodies. The tongue-shaped blank 50 may be formed as shown in Fig. 5C. Such formation can be done by a separating operation and the tongue-like blanks are conveyed as integral blanks. The connection can also be made with insertion of the tongue-like portion into the displacement groove. The tongue-like portions 30 are separated from the blank as shown in Fig. 5D and inserted into the displacement groove 21 as shown in Fig. 5E. The tongues may be inserted into a groove of a strip panel containing the strip or into a groove formed in another adjacent panel.

6A-6D illustrate alternative methods for connecting the spring portions 40 to the main tongue-shaped body 31. FIG. One or several holes 34a or cavities 34b may be formed. 6E can be formed by combining several spring portions with different lengths of displaceable tongues positioned along the main tongue-shaped body 31.

Figures 7a-7c show the locking of the two panels 1, 1 '. Figure 7a shows that the tongue 30 is tilted downward during locking and Figure 7c shows that the tongue 30 is tilted upward in the locked position so that the outer portion of the rigid tongue body has the displacement groove 21 Forming an upper contact surface 22 and an inner portion forming a lower contact surface 23. This means that it is advantageous to connect the spring portion to the upper portion of the main body. The spring portion as well as the lower portion can be connected into a fixed groove which opens downward.

8A-8E illustrate a method of forming and inserting displaceable tongues into the edge of a panel that may be used, for example, when the tongue-shaped bodies are delivered as loose elements or as extruded sections that are cut into defined lengths. The tongue-shaped bodies 31 are displaced, for example, parallel to their lengths and the spring-portion blanks 60 are displaced toward the tongue-shaped bodies, whereby when the tongue-shaped body 31 is displaced in its longitudinal direction, (40) are separated and connected to the tongue-shaped body. The displaceable tongues 30 are thus inserted into the displacement groove 21.

Figures 9a-9c illustrate that the tongue-shaped body blank can be used as an extruded section (Figures 9a, 9b) or by machining the panel (Figure 9b), for example from machined wood, wood / plastic or plastic panels, (Fig. 9C).

Figures 9d and 9f can be formed by displaceable tongues that are connected to rails that may include extruded sections (Figure 9e), or molded sections (Figure 9g).

Figures 10A-10D show preferred embodiments of displaceable tongues 30. FIG. 10A shows overlapping spring portions 40. FIG. 10B shows a spring portion that is attached to the tongue-shaped body. Figure 10c shows spring portions with only a flexible spring body at one edge. FIG. 10D shows spring portions connected to each other.

Figure 10E shows a tongue 30 with a spring portion connected into a tilted displacement groove 21 of a strip panel comprising a locking strip 6. 10f shows a displaceable tongue 30 inserted into the edge of the groove panel including the locking groove 14. Figure 10g shows a locking system locked in a vertical direction only. The strip 6 does not have a locking element. Horizontal locking can be achieved, for example, by friction between long edges.

11A-11G, the spring portion may also be formed of a flexible material such as, for example, rubber. The flexible portions may even be located at a distance between each other along the main tongue body in this embodiment and the separate components may be compressed and displaced beyond the first vertical tongue-like plane Tp1 as shown in Fig. have. Preferably, the flexing cavities 33 are formed in the main spoon-shaped body to permit such compression. The spring portions 40 are preferably asymmetric in the longitudinal direction of the displaceable tongue 30.

Figures 12A-12I illustrate several fixed cavities 33 and flexing cavities 34 that secure the spring portions and extend beyond the vertical tongue plane Tp1 to allow for compression or flexural displacement therein. 31). ≪ / RTI > The figures show that the tongue-shaped body 31 and the spring portions 40 are asymmetric in the longitudinal direction of the tongue-like portion.

13A-13F can also be connected as separate parts, for example a frictional connection 36, where other parts of the displaceable tongue can be attached to the main tongue body 31 as shown in Fig. 13D . 13E shows that a frictional connection 36 can be formed and attached to the main tongue-shaped body 31 so that the frictional connection can be displaced by turning. Such a turning device can be used as a link to displace the tongue part outwardly from the displacement groove when the tongue-like side presses the sides along the joint by side pressure.

Figs. 14A-14D illustrate alternative methods for forming displaceable tongues that include separate spring portions 40. Figs. The spring portions are inserted into the displacement groove (21). The main tongue-shaped body 31 is then inserted into the displacement groove and connected to the spring portions 40.

Figs. 15A-15F illustrate a preferred embodiment of a spring portion suitable for insertion into the displacement groove 21. Fig. Figure 15a shows the spring portion 40 from above and Figure 15b is a side view. The spring portion includes a frictional connection 36, a snap connection 44 and a holding connection 45 vertically positioned on the opposing upper sides of the spring portion. The snap and holding connections are displaced along the spring body 41. The main tongue-shaped body 31 is automatically snap-connected to a spring portion which is connected to the displacement groove by a friction connection 36. Figures 15e and 15f show cross-sections during locking. The snap connection 44 is fixed to the main tongue body and the holding connections are slid against the tongue body 31 during locking. The spring portion 41 can of course also be attached to the main tongue body before it is fixed into the displacement groove 21.

Figures 16a-16g show that snap connection to the main tongue body 31 only when the spring portion is already in the displacement groove 21 because the spring portion only includes the snap connection 44 and does not include the holding connection Lt; RTI ID = 0.0 > 40 < / RTI > Fig. 16A shows the spring portion viewed from above, and Fig. 16B shows a side view. Preferably, the snap connection 44 is located in the upper portion of the spring portion 40.

17A-17G illustrate that the bendable cavity 33 can be formed in the main tongue-shaped body 31, this embodiment being characterized in that the majority of the spring body 41 extends beyond the vertical tongue-shaped plane Tp1 Allowing it to be displaced.

18A-18E illustrate that the tongue-shaped body 31 can be formed as a three-dimensional molding component and can be optimized to snap connection to the spring portion. The material savings are mainly obtained by the fact that the plastic material of the tongue-shaped body 31 may be less expensive because flexibility is not required. 18E is a side view of Fig. 18D. The spring portion protrusions 46, 46 'are displaced in the displacement cavities 33, 33' during locking.

The described tongues are intended to be used on short edges of the panels including locking systems on long edges that can be locked by angling. However, the tongues may be used on short and / or long edges.

The principles of the present invention can also be used to form two-piece tongues that are not flexible and are used, for example, to displace along a joint during locking. The separate parts can be used, for example, as wedges that create a movement of the tongue-like portion perpendicular to the edge during displacement.
