is a floor covering has become known, are connected to the four square base plates by means of a connecting element, which has the shape of a cross, from whose arms protrude knobs and engage in holes on the underside of the floor panels. The cross is supported on the ground with its underside. A safeguard against lifting one floor panel over the other does not offer the system.
Similar connecting elements describe the DE 10 2011 012 023 A1
. DE 4222 936 A1 and 10 210 014 131 A1
, There strip-shaped or plate-shaped connecting elements are shown, of which the knobs are up. Partially they have a ribbed profiling to hold themselves in the holes of the floorboards. An upstanding center bar serves to maintain a distance to form a gap between the plates. A spoke wheel-shaped embodiment of this type shows the DE 202 01 654 U1
for the floor slabs of an exhibition stand. The DE 3902 419 A1
describes pressed from scrap tires plates in which pits are formed in recesses on the rings can be pushed to connect.
There is a great deal of floor coverings on the market, such as engineered parquet or laminate floors, whose connection works according to the tongue and groove system. Projections on one side of the plate engage in recesses on the other side of the plate adjacent plate and there are connected to each other either by snapping or by pivoting tensile strength. An example of the snap connection is in the DE 60213161 T2
shown, the swinging shows the DE 10 2005 034 0494 A1
Finally, in 32a to d
of the WO 00 2916 926 A1
a double-T connector is shown, which engages in a respective groove in the side surface and at the bottom of the plates. To connect the two plates must be joined together at an offset in the direction of the joint and then moved horizontally in the correct position in the joint direction.
Task and solution
The object of the invention is to provide a floorboard system, which creates a connection between the adjoining floorboards in all directions, ie horizontally across and along the joint, and in the vertical direction, wherein the connection system comprises a connector which in addition to its connecting the floorboards Function allows a flexible and uneven compensating support on the ground and also at several, at an angle to each other extending sides of a floorboard is used.
This object is achieved according to the invention in a floorboard system of the type mentioned in that recesses are present at least in the longitudinal sides, engage in the Eingreifvorsprünge for positive securing the vertical position of a joint adjacent floorboards. When connecting one of the floorboards to the other floorboard, the flexible connector is movable relative to at least one of the floorboards into an engaged position, eg the connector can be pressed into the joint from the bottom or the floorboard to be connected can be pushed in from above the already attached to the other floorboards and abgestüzten for example on the ground connectors are pressed. The engagement projections are barb-like acting and designed for Securing the horizontal position are provided in the transverse direction like a clip on the longitudinal sides engaging gripping elements on the connector.
The invention includes a connection system with a flexible connector, which has a dual function, namely on the one hand to secure the floorboards form fit for all relevant degrees of freedom to each other and on the other hand to form supports that can be supported on the ground, can compensate for unevenness of the ground and ensure that the form-solid floorboards between the connectors have a ground clearance. Between these, the floorboards can be self-supporting. The system thus places lower demands on the ground and is nevertheless flexible and easy to assemble.
In order to optionally allow a laying of the floorboards without distance from each other (zero joint) or with a distance joint, either different sized connectors can be used or it can be provided on the floorboards and / or the connectors already alternative securing positions that the two (or define multiple) joint distances.
An advantageous embodiment of the invention comprises a connector having a flexible body with a support surface on its underside, lateral, upwardly disposed, for engagement on the longitudinal sides of the floorboards provided gripping elements and on a central web laterally projecting engagement projections, for engagement in the laterally open recesses of the floorboards to be joined are formed. They are advantageous by their flexibility able to provide when taking their final position for both the engagement of the Eingreifvorsprünge in the recesses and for the positive engagement of the gripping elements to ensure the cohesion of the floor panels, for example in the form of lateral webs from below on the inside of the long sides like a clamp attack.
The dimensions of the recesses in the longitudinal direction of the joint in the longitudinal sides and the corresponding dimensions of the connector are matched to one another, so that there is also a positive connection in this direction. It is advantageous that the connector has a profile that is the same in the longitudinal direction of the joint, so that it can also be produced as a section of a rod profile.
The engagement projections may be latched into the recesses on the sides of snap-in members on the central web of the connector. This connector can be attached to one side of a floorboard from below and then the other floorboard can be attached from above and pressed down, pushing back the latch-like resilient engagement projection until it snaps into the recess on this floorboard.
This connection system with a connector which can be pressed from below into the gap between the adjacent sides of two floorboards or by a vertical parallel displacement parallel to the joint and has barb-like engagement projections, is advantageous for laying floorboards advantageously used, however also in addition to and completion of the drawings and description also included embodiments in which a connection is made by swinging. It is thus possible to provide this connector, for example, in addition to the swing-in connectors described below, or to connect floorboards entirely to this type of connector, that is, by pushing in the connector from below or depressing the floorboards to be connected.
All of these compounds provide significant benefits. The floorboards are not over their entire length and width on the ground, but at precisely defined locations, namely the support surfaces of the connector. These can also be structured or ribbed if elastic support and even better adaptation to the substrate is desired. Also a production with different elasticity between the gripping area and the support area, e.g. by multi-component injection molding or continuous casting is possible. The connectors can also be used in a floorboard both between the longitudinal sides and on the front sides, so also at an angle to each other laid floorboards. In all versions, the connection between the floorboards by a load, so committing, reinforced, although without them a secure connection in all relevant degrees of freedom exists. Unevenness in the ground is less disturbing for a level installation of the floorboard system, because there is a gap between the undersides and the ground, which also serves to dissipate penetrated moisture or to lay cables, etc.
The floorboards are in particular made of plastic injection molding, for example made of natural fibers reinforced and / or filled plastic, ie fiber composite (NFK), based on polyolefin, epoxy, polyester, phenolic or polyamide. For your rigidity and also for creating channels under their preferably provided with a non-slip structure surface they are ribbed in the longitudinal and transverse directions. Thus, they are designed so that they bear even when resting only at their endpoints the desired loads without significant deformation. Furthermore, they are weather-resistant and easy to clean, so they are particularly suitable for terraces and balconies. A laying can be done in different patterns and, since there are numerous connection options (recesses and / or projections) in relatively short distances on all sides, it is also possible to adapt the covering to the structural conditions by shortening the floorboards.
These and other features will become apparent from the claims but also from the description and drawings, wherein the individual features each alone or more in the form of sub-combinations in an embodiment of the invention and in other fields be realized and advantageous and protectable Can represent versions. The subdivision of the application into individual sections and subheadings does not limit the statements made thereunder in their generality.

Description of preferred embodiments
1 shows a floorboard 11 , which is made by injection molding of a natural fiber composite (NFK). Plastics such as polyolefins, epoxies, polyesters, phenolic or polyamide, which are filled with natural fibers and thus also reinforced, are particularly suitable for this purpose. The floorboard has a top 12 Made with a non-slip structure like textured longitudinal ribs 13 is provided. It is from sides or side walls, namely long sides 14,15 and end faces 16 , limited, the, like 3 you can see the floorboards 11 surround. The floorboard thus has a flat box-like shape whose interior, so its bottom, continuous longitudinal ribs 17 . 18 has, of which the longitudinal ribs 17 to the same level as the pages 14 to 16 , while in between each lower longitudinal ribs 18 run. At their level, transverse ribs are provided, which also stiffen the floor boards in the transverse direction. Between the ribs 17 . 18 are channels 19 formed, in which cables, lines, etc. can run. In conjunction with the relatively hard material thus creates a form-solid floorboard that is resistant to bending and breakage and still can be produced inexpensively from ecologically advantageous material.
In the in the 1 to 14 shown embodiments have the pages 14 . 15 . 16 recesses 20 , here formed as cutouts, to the lower edge 21 the sides are open. On the long side 14 protrude horizontally gripping elements 9 in the form of receptacle projections 22 out, which are designed as flat tongues whose top on the level of the cutout top edges 26 lies. They have a recess in the middle 23 in the form of a through hole with a countersink 24 at the top. Matching are on the opposite longitudinal side 15 each complementary gripping elements 9 in the form of two engaging projections 25 provided, the top also at the level of the cutting top edges 26 lies while their bottom is at the level of the side bottom edges 21 lies. The receptacle projections 22 and the engagement projections 25 are each of two recesses 20 the long sides flanked. The engagement projections 25 are narrower than the receptacle projections 22 , The engagement projections 25 are apart from the areas near the front ends 16 , arranged in pairs so that they the receiving projections 22 lie opposite, so in an assembly of two floorboards on both sides next to the recording projections can intervene. In each case, when viewed in the longitudinal direction of the floorboard, there are spaced apart a plurality of groups each of a few pairs of engagement projections 25 provided with opposite receiving projection, wherein in the middle of two groups are provided with a smaller distance from each other.
This constellation is such that when joining two floorboards each with a longitudinal side 14 adjacent to a longitudinal side 15 is a connection with a joint with theoretically zero width, hereinafter referred to as "zero joint" would result, in which the floor boards rest over their entire length on the ground. This could, in each case before the preparation of the adjacent Ground floor, the previous on the recesses 23 in the receiving projections 22 are screwed to the ground. It resulted in a horizontally secured in the longitudinal direction and vertical against lifting positioning, but in the transverse direction only by screwing. In addition, in such a case, the substrate should be very flat, because even a small increase, which is eg in the middle of a floorboard, would cause an unstable situation.
The following embodiments make it possible to avoid these limitations. In addition shows 4 a connector 30 made of a flexible material, a plastic injection-molded material with rubber-like properties, in the form of a plate-shaped body 29 with a support surface 31 forming bottom 31 , a towering, a projection 32 for engaging in the recess 23 in the receiving projection forming knob, with a likewise projecting upstanding support bar 33 on one longitudinal side 28 , and with on the opposite longitudinal side 37 upwardly projecting securing projections 34 in the area of the corners, which serve as later explained security elements. Between these projections 34 is a gap 35 educated. The support bar 33 has on its inside 39 in the middle a projection 40 , which is when joining connector and receiving projection 22 in a recess 41 at the foot of the cradle fits and the connector in addition to the projection 32 (Knob) secures against pulling in the transverse direction. In the plate-shaped body 29 of the connector 30 are adjacent to the two transverse sides 36 oblique insertion recesses 38 educated. Because of the details of the design and sizing of the connectors 30 and other elements of the floorboard system in this patent, reference is expressly made to the drawings.
5 shows a detail of two floorboards 11 before their connection to the floorboard system 10 in plan view. At the one from the long side 14 the left floorboard 11 projecting receiving projection 22 is the connector from the bottom 30 according to 4 assuming his lead 34 or knob in the recess 23 engages and because of its flexibility the connector 30 on the receiving projection 22 sets. For this purpose, the head of the knob may be slightly thickened and / or barb-like beveled and into the countersink 24 insert. The support bar engages behind the side wall 14 , The attachment of the connector 30 at the receiving projections 22 can already be done at the factory, with other attachment options such as gluing, welding, 2-component syringes or the like. possible are. The connectors 30 but can also be installed only immediately before joining the floorboards, wherein the user can feed all or some of the receiving projections with connectors depending on the requirements or the ground condition. Moreover, he can then choose whether he has connectors for laying with a joint 46 with a defined distance between the sides of the floorboards, hereafter referred to as a distance joint, or used with "zero joint". This increases flexibility and reduces the types available in the trade.
The in the 6a, b and 7a, b shown sections according to the section lines VI and VII in 5 show two phases of joining two floorboards. The recording projection 22 the in 5 left floorboard is with the connector 30 provided in the manner described, it being recognized that the projection 32 (Knob) a thickened and somewhat barb-like head 39 which extends into the countersink 34 insert and so the connector 30 on the receiving projection 22 guaranteed. The right floorboard is introduced at an insertion angle α so that, as out 7a it can be seen, the engaging projection 25 in the room 58 penetrates the recess 20 and the introductory recess 38 form between themselves when the right floorboards in the insertion (arrow 41 ) is pushed into or into the left floorboard. At the same time, the engaging projection slides 25 with its underside over the securing tabs 34 , supported by the insertion bevel 42 (please refer 4 ). The size of the insertion angle α depends on the dimensions of the floorboards and in particular of the connector 30 , there mainly the height of the securing projections 34 and will be between 10 ° and 30 °. In the present example, it is about 20 °. When the engaging projection 25 until the end in the introduction recess 38 has penetrated, then comes with a middle projection 44 provided inner edge 43 of the engaging projection 25 from the top of the securing projection 34 free and can lock in front of this ( 7b ). The middle projection 44 reach into the depression 45 one, the insertion bevel 42 the securing projections in the middle interrupts (see also 4 ). It also secures the connection in the direction parallel to the joint 50 that lies between the two floorboards 11 forms. This fugue is made in its existence and size by the dimensions of the connector 30 , mainly due to the position of the projection 32 , certainly. In the 6a to 7b is a dimension of the connector 30 shown, which produces a distance joint of eg 5mm, with an offset of the projection 32 and corresponding dimension of the support bar 33 would create a "zero joint".
It can be seen that this connection system performs a multiple function. It stores the floorboards at a distance 48 elastic with the support surface 31 of the flexible connector 30 on the ground 47 and secures the connection of the floorboards 11 both in the transverse direction, as well as in longitudinal joints as well as in the vertical direction, ie against lifting. The connection in the transverse direction is made by that, like the 6a and 6b show the support bridge 33 and his lead 40 the inner edge 49 the side wall 14 the left floorboard 11 engage behind while the inner edge 43 the side wall 15 the right floorboard 11 from the security tabs 34 is engaged behind. The connector 30 Thus, forms a bottom of both floor boards engaging flexible clip, which is additionally secured by an operating load from above. The connection in the vertical direction is elastic, because of the engagement projection 25 lies on the inner surface 51 of the flexible connector 30 on.
The 8th to 10 show different laying patterns of floorboards 11, without offset next to each other ( 8th ), by about one third ( 9 ) and at an angle to each other ( 10 ). The arrangement of the receiving and Eingreifvorsprünge 22 . 25 allow these and a large number of other variations of the installation. The connection of the longitudinal sides with the end faces can not be done in the manner described by pivoting, if at the same time a connection between longitudinal sides is made. Connection systems that make this possible, but will be described below.
11 shows a variant of the connection between receiving projection 22 and connector 30 in which the receiving projections 22 are divided into two parts and tapered towards each other so that the dovetail-shaped projection 32 at the connector 30 forms a dovetail connection with the receiving projections.
The 12 to 14 show a variant of the connector 30 who has a shoe 52 for receiving the recording projection 22 having no hole in this case 23 needs to have. The shoe is designed as a flat rectangular compartment and has on its upper side a stop bar, which serves as a spacer 53 between the two long sides 14 . 15 to the definition, ie the joint width, the distance joint 46 serves. 12 shows the connector in an oblique view and 13 after its attachment to a floorboard 11 , 14 shows on average XIV-XIV, due to the flexibility of the connector 30 at the receiving projection 22 this like a foot in the shoe 52 can be inserted, wherein the support bar 33, so to speak, behind the hacking of the receiving projection engages and, as in the dovetail design, the connector 30 at the floorboard 11 sets. The side projections 54 at the connector 30 on both sides of the shoe 52 serve, as with the dovetail design, as lateral guidance of the connector on the floorboard. The connection with the adjacent floorboard 11 as happens in particular in the 6 and 7 shown, with the Einführvertiefungen here for simplicity 38 are not shown or because of the flexibility of the connector can also be omitted.
The 15 to 17 show a variant in which a laying with zero joint and gap joint is already provided. In this embodiment, the attachment of the connector 30 at the receiving projection 22 as with the 4 to 7 described. Also the in 16 in an oblique view shown connector 30 similar to its features 4 , however, are in the area of insertion recesses 38 three grooves or cuts 55 at the bottom of it. In it fit strip-shaped gripping bars 56 coming from the bottom of the engaging projections 25 protrude down. If, how 17 shows, the connector 30 by snapping the knob 32 with her head 39 in the hole 23 and the countersink 24 attached to the receiving projection, according to the 1 to 7 equal, then the engagement projection can 25 or, as not shown here, two pairs of adjacent Eingreifvorsprünge in the room 58 be swung. Depending on the laying request with zero joint or gap, the gripping ribs grip 56 in the two front or rear grooves and thus determine the distance between the two floorboards from each other. In this case, in the "zero gap" version, the rear locking projection is 34 not engaged. Here can with an execution of the connector 30 various laying principles are accomplished.
The 18 to 25 show a preferred embodiment of the connection system. In 22 is in oblique view and in 18 on average, one connector each 30 shown for a "zero-gap" layout and a laying with gap joint. The flexible material connector has a constant profile over its length in the joint direction, which also allows production from an extruded profile, and has a plate-shaped body 59 with an upper inner surface 51 and a lower support surface 31 , This is in the case of 22 ribbed in order to increase the flexibility and adaptability to a level surface and also the position of the floorboards 30 to improve on the underground. The flexibility in the area of the support surface 31 Without letting the rest of the body become too soft could also be achieved by different material properties in the injection or extrusion process, for example by 2-component spraying.
From the body 59 protrude laterally securing projections 34 upwards, which in their function the support bar 33 and the security tabs 34 according to the execution 4 correspond. At a central pier 60 are gripping elements 9 in the form of laterally projecting from the central web engagement projections 25a provided, which on its underside a rounding 62 exhibit. at 22 is the top of the engagement projections 25a flat, so that the middle part of the connector 30 T-shaped. At the connector 30 to 18 protrudes from the middle of the two laterally extending Eingreifvorsprünge 25a a spacer 53 in the form of a strip-shaped projection upwards, but which is much narrower than the central web 60 ,
23 shows an oblique view of a floorboard 11 , It can be seen that the floorboards used for the designs according to the 4 and for the designs 18 to 22 are provided, have no gripping elements in the form of receiving and Eingreifvorsprüngen, but only recesses 20 at regular intervals over the long sides 14 . 15 and end faces 16 are provided distributed.
This is a great advantage not only for the production, but also for storage and assembly, since the floorboards do not have to be brought into a specific orientation when laying. The recesses 20 (see in particular on 19 ) are in the pages 14 . 15 . 16 provided and consist of horizontally aligned incisions or openings (see also 21 ). Between them and the lower edge 21 of the pages, these are set back slightly, leaving a room 61 for the central pier 60 arises.
Fi g. 19 now shows the joining of two floorboards 11 , Although it would be possible and reasonable to do so, here is the connector 30 at the to be applied, right floorboard 11 been attached before joining. It engages an engagement projection 25a in the recess 20 on the right floorboard 11 and the securing projection 34 on this side grips behind the side wall 15 , The so with the right floorboard 11 connected connectors 30 can now with its engaging projection 25a into the recess 20 the left floorboard 11 be pushed, what the rounding off 62 allows. The strip-shaped securing projection 34 on the left, when inserting the front side of the connector slides under the bottom edge 21 the side wall 14 the left floor board forward until it swings down into the aligned position, the inner edge of the side wall 14 engages behind 20 ). A rounding off helps too 63 on the inner edge of the securing projections 34 ,
20 and 21 show the completed joint with gap gap in the cut. It can be seen that the engagement projections 25a the floorboards 11 secure against vertical displacements while the securing projections 34 the floorboards 11 hold together in the manner of a clip against pulling apart. The spacer 53 at the top of the cross-shaped central portion of the connector 30 guarantees a uniform dimension of the gap 46 , As 21 shows, the connectors on each of the numerous recesses could 20 However, this is not necessary. It can be seen that even here a load on the floorboard system additionally strengthens and secures the connection and ensures a certain flexibility by the body 59 of the connector 30 between the floorboards and the ground 47 balancing and slightly flexible, so that it is also soundproofing.
The 24 and 25 show the the 20 and 21 corresponding representations for the execution "zero joint". The angular arrangement of 26 is also with connectors 30 on all possible connection points, say recesses 20 the floorboards 11 , shown what is certainly necessary or appropriate only in exceptional cases. As before at 10 mentioned, the connections can be performed by pivoting in such over-corner joints only when this happens around a pivot axis.
The 27 to 35 show a connection system in which the two floorboards to be joined 11 can be securely coupled together without pivoting over the connector 30. 27 shows in cross section and 28 in an oblique view, the connector for a "zero joint" connection, the plate-shaped body 59 with a support surface 31 has on its underside. Protective protrusions projecting on both sides of the body 34 high on the inside edge with a fillet 63 are provided. The connector 30 is also made of flexible material and has a consistent over its length in the direction of joint length profile, which also allows the production of an extruded profile. A central pier 60 protrudes from the inner surface 51 of the body 59 up. This is followed by a narrower bridge area 71 on, at the top of Eingriffvorsprünge 25b connecting the upper part of the middle bridge with an arrow-like shape. The engagement projections are barb-like obliquely downwardly directed resilient pawls which press against each other from above at the central web in the narrower land area 71 that there are depressions 70 form, create or at least approximate.
29 shows the attachment of the connector 30 on a floorboard 11 as they are in 23 is shown, ie with recesses 20 in the sides acting as side wall engaging slots of a longitudinal dimension matching the length of the connectors and having a recessed space for the central web 60 creating section 73 , A connector 30 is inserted in such a recess, wherein, as well 30 shows, the safety projection 34 behind the inside edge 49 the side wall 15 engages and one of the engaging projections 25b with its front, ie lower end on the lower surface 74 the recess 20 rests. In this way, the in 30 left floorboard 11 to be prepared ( 29 ). This preparation is easy to do by the publisher, so it does not require any measures in production and distribution.
30 shows the process of connection. The right floorboard 11 will be in the same orientation as the one already on the connector 30 and its support surface 31 on the ground 47 supported left floorboard 11 , So horizontally inserted from above, ie in the direction of arrow 75. This penetrates with a rounding 65 provided lower outer edge 66 the side wall in the gap 67 between the securing projections 34 and the engaging projection 25b and pushes it back, taking it into the depression 70 can put in it. Because of the securing projection 34 already behind the inside edge 49 When the side wall grips, the right floor board is held in its sideways position and can not be held by the engagement projection 25b applied sideways pressure be pushed back to the right. For this it is important that the securing projections 34 project so high that the portion lying below the recess 76 the floorboard 11 already in the gap 67 has penetrated before the section 76 the engagement projection 25b reached. If the portion lying below the recess 76 with its upper edge, namely the lower surface 74 the recess 20 , the outer end of the engaging projection 25b In the previously described, not shown alternative embodiment with engagement projections which are formed as a solid triangle, in addition to an elastic compression of the engagement projections, the entire unit of both engagement projections becomes elastic a little to the left and possibly the safety projection 34 bend something to the right so that the below the recess 20 lying section 76 the side wall in the between inner surface 51 , Securing projection 34 , Middle jetty 60 and engaging projection 25b penetrates and remains secured there, as well as in 30 presented version. This insertion process is the same as it was when attaching the connector 30 was performed on the left floor boards, there by pressing the connector 30 in the gap 67 from below. The completed connection, here with "Nullfuge", is in 31 shown.
It can be seen that here a connection system was created, which is simply provided with slit-shaped recesses in the sides floorboards 11 via flexible connectors which can be pressed into the joint from below 30 creates a secure connection. The connector has a clip which engages behind both side walls and a shaft which can be inserted from below into the joint between the floorboards and the engagement projections, which penetrate into recesses on the side walls of the floorboards and hold themselves there.
The 32 to 35 show an embodiment for a defined distance joint 46 , In the rest of the same education and function here is the middle bridge 60 or shaft also not the arrow-like or barb-like protruding engagement projections 25b provided and beyond this with a spacer 53 serving upper extension whose thickness determines the joint width. Incidentally, the individual features and the connection function are the same as based on the 27 to 31 described.
The 36 to 38 show a simplified embodiment of the in the 15 to 17 illustrated connection. Out 36 it can be seen that the connector 30 a not obliquely recessed to Einführvertiefungen, but essentially flat body 59 has, in its flat inner surface 51 the three grooves 55 are formed. The support bar 33 and the securing projections 34 are formed as continuous webs. 37 and 38 show in cross section and in a bottom view the connection of two floorboards with the connector 30 to 36 , The floorboards have a receiving projection 22 on how he is in 17 is shown and an engaging projection 25 with two gripping bars 56 as in 15 shown. 37 shows the connection with "zero joint" in a section along the line XXXVII in 38 , The gripping bars 56 In this case, grab the support bar 33 closer grooves 51 one. You could also use them in the two more distant grooves and would thus create a connection with distance joint. In the arrangement of further grooves or omission of one of the gripping ribs different joint widths of distance joints could be achieved in addition to the zero joint. The insertion of the engagement projection 25 is due to the flexibility of the connector 30 possible.
38 shows the connector 30 in transparent view. It can be seen that here only one engagement projection 25 Use, which further increases the flexibility of the system arrangement.
