Description

  • The The invention relates to a panel, in particular floor panel, with a Core of wood-based material or wood-plastic mixture, one Top and bottom, which are at least two opposite each other Side edges such a profiling corresponding to each other has that two identically formed panels by a in the Essentially vertical joining movement in horizontal and vertical direction can be connected and locked together, wherein the locking in the vertical direction by at least one in a parallel to the top and at the first side edge of a panel introduced into the core, forming a groove bottom Nut arranged, movable in the horizontal direction locking element is feasible, in the joining movement behind a the second side edge of the second panel formed locking edge snaps.
  • The The invention further relates to a device for locking two interconnected panels, in particular floor panels with a core made of wood-based material or wood-plastic mixture, in one Direction V perpendicular to a top and a bottom, consisting from one provided in a in the core of the first building board, parallel inserted to the top groove extending locking element for automatically snapping into one in the core of the second Building board provided parallel to the top groove, if when connecting the building panels by a vertical lowering movement both grooves come to cover, with the locking two building panels in a direction parallel to the top at a Side edge I a protruding lower lip with an outer, upwardly projecting projection and on the opposite side edge II one to the Bottom facing recess is provided, leading to the projection is formed correspondingly.
  • A generic panel is for example from the EP 1 650 375 A1 known. The locking element used there is designed as a flexible spring element, which is connected at its two ends, for example by frictional engagement with the groove. In the area between these two attachment points, the spring element protrudes from the groove receiving it and engages in the groove of the neighboring panel provided for this purpose, when both panels are connected to one another. During the joining of two panels, the middle part of the flexible spring element is pushed into the groove receiving the spring element. This is possible by the specially selected geometric shape of the flexible spring element. Such a flexible spring element can be made for example by injection molding of a plastic.
  • The necessary for locking flexibility of the spring element is determined by the shape of the locking element. Thereby the structure of such a locking element is complicated.
  • adversely is also that the locking element and the building board technologically conditionally separated and in separate Manufacturing steps must be made. You need to subsequently in an additional step be joined together. Since the locking element off a deviating from the wood material of the building boards plastic material exists, the manufacturing tolerances of two separate Manufacturing processes for components of different materials be aligned consuming and costly. moreover need for each panel length and width separate flexible spring elements are produced, their shape the dimensions of the building board is adjusted. This is also costly and expensive.
  • At the Laying a floor consisting of individual panels, usually need for the edge areas of the floor some panels are cut to the correct length and / or width. It is in the known embodiment, the flexible Severed spring element. Each of the two parts of the flexible spring element is then only at one point with the they connected receiving groove, so it does not during transport is more sufficiently secured against falling out and laid in the Condition ensures no secure locking with the adjacent panels is.
  • It So have many different panel lengths and -widths are offered. For each of them must suitable flexible spring elements are manufactured, which is very expensive and is impractical in manufacture. Different width panels It must offer as a consistent implementation of the market needs to be understood according to individual products. The need for many different widths of panels is therefore the cost pressure, the increased tool and device requirements as well as the increased logistics costs for different widths Contrary to locking elements.
  • From the WO 03/083234 It is known to use a substantially rigid locking element. In order to ensure the mobility of the locking element, an elastic material, for example rubber, is arranged between the latter and the groove base.
  • An elastic element changes its shape under the influence of pressure. If the elastic element is chosen as long as the receiving it Groove, the elastic element swells during the locking process during compression laterally out of the groove and is then squeezed in the junction between the Panee len, which excludes a completely tight connection point. Therefore, the elastic element will be chosen slightly shorter than the length of the groove.
  • At the Laying the panels is usually necessary, for example on the walls, panels to the desired length to shorten, the elastic element then shortened and in this case flush with the new end of the panel concludes. When laying it comes to the chilling out of elastic element from the groove. The skilled person will therefore try shorten the elastic element slightly more than the panel, to counteract this effect. For this to be possible, may the elastic element not over the entire length be locked in the groove of the panel. But that's just it insufficient against falling out, for example during transport, secured.
  • adversely Consequently, the production of the panels is expensive is and must be done exactly as an inaccurately inserted in the groove elastic element the stability of the connection of two Impacted panels, and that shortening the Panels by the end user is only partially possible.
  • From Based on this problem, the invention has the task to, a mechanical locking system for panels, in particular for floor panels, provide a secure lock guaranteed even with cut panels and a cost-effective and fast production allows.
  • Draw according to the invention the generic panels for problem solving characterized in that between the locking element and the groove bottom a compression element acting in the direction of the locking element arranged during the locking process by the locking element is reversibly compressible, without in one To expand direction along the groove.
  • By This compression element, the aforementioned disadvantages are eliminated. Unlike a flexible element, its flexibility from the special geometric design, is a compression element fully functional even after cutting. The volume a compression element is reduced by pressure. It comes So not just like an elastic element for deformation at the same total volume, ie for expansion in one direction, if another one is upset. Therefore, need along the groove no free space to be provided, in which the compressed Material can expand. Even after cutting a panel The desired length swells during installation the compression element does not come out of the groove when it is during of laying is compressed.
  • The Locking element is advantageously substantially rigid educated.
  • Preferably the compression element is rod-shaped. advantageously, For example, the compression element may be made of a compressible material.
  • One such trained compression element is particularly of Advantage, when the panel, the compression element and the locking element Delivered separately and only shortly before the actual installation be joined together. This simplifies production, because the manufacturing steps in which the parts are assembled omitted. If a conventional flexible element is used, it can come with inaccurate insertion that the flexible The element swells out of the groove during installation, thus locking it the neighboring panel impossible. Then it has to be moved panel removed and relocated after the position of the flexible element has been corrected. In this embodiment can even with an incorrectly inserted compression element the Neighboring panel to be laid properly because the compression element is simply compressible. The Standing out of the panel is thus easy to correct. Thereby the laying process is significantly simplified and accelerated.
  • The For example, a compressible element may be injected into the groove compressible mass, in particular a foam. In this case It can be online in a fast and easy way be introduced into the groove.
  • The compression element can advantageously also be designed as a mechanical spring element. Also this can be introduced in the ongoing production process in the groove of the building board. The mechanical spring element preferably has a plurality of spring arms connected to one another in an articulated manner. The groove base facing side of the locking element and the locking element facing side of the compression element are preferably formed such that they can engage with each other. For this purpose, various forms of recesses and projections corresponding to these can be provided on both sides. By this configuration, an optimal power transmission between the locking element and the Ensures compression element.
  • In a compressible material is a gas, such as air, in contain the many bubbles and pores. This gas is Compressible and is compressed when connecting two panels. there the gas pressure in the compression element is increased. Becomes the compression element is designed as a spring element, is in Compressing the potential energy of the spring element elevated. Both effects result in a force on the locking element acts and this pushes out of the groove again, when both panels are in lockable position.
  • Advantageous it is when the compression element is essentially the same Has length as the receiving groove. Through this Design can also be the locking element this length without putting in places without compression element between create cavities in the locking element and the groove bottom, which can negatively influence the stability.
  • advantageously, the compression element is locked in the groove to hold it against Falling out during transport or in the further manufacturing process to secure. If the compression element as a separate, finished trained Component, for example as a rubber hose or as a mechanical Spring element, introduced into the groove, can be used for locking, for example an adhesive can be used in front of the compression element in the groove is introduced. The locking of the compression element but can also be done by friction. In this case, the compression element be pressed into the groove, leaving it through the friction on the walls of the groove from falling out during transport is prevented.
  • The Compression element can fill the groove form fit or form cavities with the bottom of the groove. The former increases the contact surface between the compression element and the groove walls, thus ensuring stronger frictional forces, the second alternative increases the compressibility. The Compression element can also be injected into the groove. In this case may be during the curing of the injected Mass be connected to the panel. Conceivable is also that the injected material before curing foams and thereby a cohesive connection comes in with the panel. In all cases it is advantageous if the compression element over its entire length is locked in the groove. This embodiment makes it possible Cut panels to the desired length, and yet to ensure a secure locking of adjacent panels.
  • Especially It is advantageous if the locking element made of a wood material, such as MDF or HDF, or a mixture of woodworking and plastic material or made of metal. The production Such a locking element is simple and easy possible. Such a locking element, for example produced in a milling or extrusion process, resulting in both an endless processing as well as different Lengths and widths, for example, adapted to different Widths of the panels, simple and inexpensive to implement to let. Panel, compression element and locking element can then together directly in the factory, but also from the consumer Place cut to the desired length when laying become. By this configuration is prevented for any desired panel length separate locking elements to have to produce. This makes the production clear more flexible, less expensive and thus more cost-effective.
  • There the locking element no flexibility or elasticity must, it can be a correspondingly rigid material have very small thickness between 1.0 mm and 2.5 mm. This is especially necessary for thin panels. With the locking technique according to the invention can also be floor panels of a thickness of, for example 6 mm can be locked without problems.
  • advantageously, the locking element runs at its free edge obliquely, wherein the width of the locking element for Bottom increases. This embodiment makes it possible by vertically merging the two to be joined Pan the locking element into the groove of the first building board push in. As a result, complicated tilting and Rotary movements during installation prevents and so the laying process much easier.
  • Prefers is a plurality of juxtaposed locking elements intended.
  • In This case also ensures that, for example at a partially damaged locking edge, the about a blockage of the receiving the locking element provided recess has an effective connection both panels ensured by the locking elements is, which is located on undamaged parts of the locking edge are located. The same applies if, for example, by Querschüsselung panels or uneven ground do not over-profile the whole panel length is at the same height.
  • The locking in the horizontal direction is preferably carried out by means of each other korrespondie render hook elements. It has proven to be particularly advantageous to form one of the hook elements by means of a shoulder projecting in the direction of the upper side and the corresponding hook element by means of a shoulder directed toward the side edge which has the locking edge in the direction of the lower side. These can be hooked by means of a simple, substantially vertical movement into each other and thus provide a lock in the horizontal direction.
  • The Inventive device for locking two connected panels is characterized by the fact that between the Locking element and the groove bottom of the groove in the direction of the locking element acting compression element is arranged during the the locking process by the locking element reversible is compressible without expanding in one direction along the groove. The locking element is preferably substantially rigid educated.
  • With Help a drawing to embodiments of the invention will be described in more detail below. It shows:
  • 1a to c - the side view of two panels to be locked in different phases of the locking process.
  • 2 - A section through a panel parallel to the top
  • 3 - Another embodiment of two structural panels to be locked
  • 4a & b - Another embodiment of two panels to be locked in different phases of the locking process
  • 5 - Another embodiment of two to be locked panels
  • 1a shows the beginning of the locking process. The two panels 1 . 2 are arranged so that only one vertical movement along the direction V of the panel 2 is necessary to the two hook elements 11 . 13 snap into place and lock both panels. The at the bottom of the groove 5a the groove 5 of the panel 1 arranged compression element 7 is in the relaxed state and the subsequent locking element 8th stands clearly over the side edge of the panel 1 out and the locking edge 8a is still above the locking element 8th ,
  • 1b shows the next step of the locking process. The panel 2 has been moved down the direction V. The locking edge has 8a the side surface II of the panel 2 that lie below the groove 6 located, the locking element 8th in the in the panel 1 introduced groove 5 pressed. This is especially easy because the free edge 9 of the locking element 8th to the panel 2 slanting. As a result, a vertical movement is applied along the direction V of the panel 2 a force in the horizontal direction on the Verriegelungsele element 8th out. By the movement of the locking element 8th in the groove 5 in the panel 1 becomes the compression element 7 at the bottom of the groove 5a pressed together.
  • 1c shows two connected and locked panels 1 and 2 , The tops 3 both panels 1 . 2 finish flush. The two in the respective side edges I and 11 provided grooves 5 . 6 have been brought into overlap. The compression element 7 at the bottom of the groove 5a the groove 5 of the panel 1 can now expand again and pushes the locking element 8th in the groove 6 of the panel 2 , The underside of the locking element 8th lies on the corresponding side of the groove 6 and thus prevents movement of the two panels 1 . 2 relative to each other along the direction V upwards. At the same time this gets stuck to the bottom 4 aligned hook element 13 of the panel 2 with the from the lower lip 10 and its upstanding projection at the outer edge 11 , The corresponding surfaces of the recess 12 in the panel 2 and the lower lip 10 with the lead 11 of the panel 1 come into contact and thus prevent movement of both panels 1 . 2 relative to each other along the direction H parallel to the top 3 as well as along the direction V down. The two panels 1 . 2 are securely locked with it.
  • In 2 is a section through a panel according to the invention shown parallel to the top, so that from above into the compression element 7 receiving groove 5 can be seen. In the embodiment shown, a plurality of locking elements 8th with indicated oblique free side edges 9 in the groove 5 arranged. Between these locking elements 8th and the groove bottom 5a is the compression element 7 shown. In this embodiment, even with a possibly damaged for receiving the locking elements 8th provided, not shown groove 6 in the second panel 2 or on an uneven surface a secure connection of the two panels 1 . 2 guaranteed. In these cases, where some of the locking elements 8th be prevented in the designated groove 6 in the panel 2 snap the other locking elements provide 8th for a secure connection of both panels 1 . 2 , In the 2 This is indicated by a locking element 8th in the groove 5 is shown pressed.
  • In 3 are two panels to be locked 1 . 2 shown in which the locking element 8th a round bar is. In this embodiment, the two grooves 5 . 6 be made small, which simplifies the manufacturing process. In addition, the production of the locking element 8th in this embodiment, very simple. For example, it can also be bought ready. However, in this embodiment, the lock is not quite as tight as in the other embodiments given because the round bar does not fit so far into the two grooves 5 . 6 intervenes.
  • 4a and 4b show a further embodiment of a panel according to the invention. The compression element 7 is in this case made of an elastic material, such as a plastic configured. In 4a it is in a relaxed state. The locking element 8th is not in the groove 5 pressed. Both panels are for locking, like the ones in 1a to 1c shown, arranged so that only a vertical movement of the second panel 2 necessary to both panels 1 . 2 to lock. 4b shows the next step of the locking process. By lowering the second panel 2 relative to the first 1 becomes the locking element 8th in the designated groove 5 pressed. For that is like in the 1a to c shown example on the free side 9 of the locking element 8th provided a slope. When pressing in the locking element 8th in the groove 5 this will be at the bottom of the groove 5a located compression element 7 pressed together. The compression element 7 has two large contact surfaces 17 . 18 on, one of which 17 the groove bottom 5a and the other one 18 the locking element 8th is facing. The contact surface 18 is provided with recesses and / or projections. The the compression element 7 facing side of the locking element 8th is designed to correspond to these recesses and / or projections. Both surfaces interlock, whereby an optimal power transmission is ensured.
  • Between the two contact surfaces 17 . 18 has the compression element 7 a plurality, in the example shown 2 , articulated struts 19 on. These are when pushing together the compression element 7 shifted against each other and thus absorb the energy in the form of potential energy. After both grooves 5 . 6 were brought to cover, move the struts 19 and thus the compression element 7 and the locking element 8th back to their starting position. Due to the special design of the compression element 7 it only comes to a compression in the direction of movement of the locking element 8th , In other directions, especially in the direction of the groove 5 perpendicular to the plane of the 4a and b there is no compression or expansion. It is also conceivable, for example, the compression element 7 as a hose of a flexible material, such as rubber, form. Even then, the compression element could 7 in the direction of movement of the locking element 8th be compressed, without that it would expand in other directions, the compression element 7 would let out of the groove on the sides.
  • In 5 are two panels according to the invention 1 . 2 shown in the first phase of the locking process (see. 1a ), in which the locking element 8th against falling out of the groove 5 is secured. For this purpose, the locking element 8th on its underside a triangular in the present case formed projection 15 on. In the groove 5 that the locking element 8th receives, is at the bottom of a recess 16 intended. During the manufacturing process, the separately produced locking element 8th in the designated groove 5 pressed in, with the projection 15 into the recess 16 locks. As a result, advantageously at the groove bottom 5a located compression element 7 already compressed a bit, so that a bias is built up. By in the direction of movement of the locking element 8th elongated configuration of the recess 16 is the locking element 8th anyway in the groove 5 in the direction of the groove bottom 5a movable. It's just a movement out of the groove 5 hindered out. The lead 15 can also be configured in another form and also at the top of the locking element 8th are located. It is only necessary to ensure that even in the groove 5 located recess 16 is arranged and configured so that a proper function is guaranteed in the sense just described.
