Definitions

  • the invention relates to a floorboard system comprising floorboards made of structurally sound material, which have an upper side, a lower side and surrounding sides, namely longitudinal and end sides, with a connection system for the adjoining connection of the floorboards to one another, which has recesses engaging in recesses

  • 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.

  • 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.

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.

  • a laying can be done in different patterns and, since there are numerous connection options (recesses and / or projections) on relatively short distances on all sides, it is also possible to adapt the covering to the structural conditions by shortening the floorboards.
  • Fig. 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.

At their level, transverse ribs are provided, which also stiffen the floor boards in the transverse direction. Between the ribs 17, 18 channels 19 are formed in which cables, cables, 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.

  • FIGS. 27 to 35 show a connection system in which the two floorboards 11 to be joined can be securely coupled to each other via the connector 30 without pivoting.
  • Fig. 27 shows in cross section and Fig. 28 in an oblique view, the connector for a "zero joint" compound having a plate-shaped body 59 with a support surface 31 on its underside. On both sides of the body projecting securing projections 34 high, which are provided at its inner edge with a fillet 63.
  • the connector 30 is also made of flexible material and has a constant length over its length in the joint direction, which also allows the production of an extruded profile.
  • a central web 60 protrudes from the inner surface 51 of the body 59 upwards.
  • the engagement projections are barb-like obliquely downwardly directed elastic pawls, which can apply under pressure from above to the central web in the narrower web portion 71, which forms wells 70 there, or at least can approach.
  • Fig. 29 shows the attachment of the connector 30 to a floorboard 11, as shown in FIG Fig. 23 that is, with recesses 20 in the sides serving as sidewall-engaging slots of a longitudinal dimension matching the length of the connector and having a recessed portion 73 providing space for the central web 60.
  • a connector 30 is inserted in such recess , being, as well Fig. 30 shows the securing projection 34 engages behind the inner edge 49 of the side wall 15 and one of the engagement projections 25b rests with its front, ie lower end on the lower surface 74 of the recess 20.
  • the in Fig. 30 be prepared left floor board 11 ( Fig. 29 ). This preparation is easy to do by the publisher, so it does not require any measures in production and distribution.
  • Fig. 30 shows the process of connection.
  • the right-hand floor board 11 is inserted in the same orientation as the left floor board 11 already supported on the substrate 47 via the connector 30 and its supporting surface 31, ie horizontally from above, ie in the direction of the arrow 75
  • the bottom edge 66 of the side wall is inserted into the gap 67 between the securing protrusion 34 and the engaging protrusion 25b, and pushes it back, allowing it to fit into the recess 70.
  • the securing projection 34 already engaging behind the inner edge 49 of the side wall, the right floorboard is held in its sideways position and can not be pushed back to the right by the sideward pressure exerted by the engagement projection 25b.
  • the securing projections 34 protrude so high that the below the recess portion 76 of the floorboards 11 has already penetrated into the gap 67 before the portion 76 reaches the engagement projection 25b.
  • the recessed section 76 has its upper edge, namely the lower surface 74 of the recess 20, passed the outer end of the engagement projection 25b, it snaps back due to its flexibility and settles on the surface 74.
  • connection system which creates a secure connection simply with slot-shaped recesses in the sides provided floorboards 11 via flexible, depressible from below into the joint connector 30.
  • 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.
  • FIGS. 32 to 35 In the rest of the same design and function of the middle web 60 or shaft is also not the arrow-like or barb-like protruding engagement projections 25 b provided and beyond this with serving as a spacer 53 upper extension whose Thickness determines the joint width.
  • the individual features and the connection function are the same as based on the Fig. 27 to 31 described.
  • FIGS. 36 to 38 show a simplified embodiment of the connection shown in Figures 15 to 17.
  • Out Fig. 36 can be seen in that the connector 30 has a body 59 which is not recessed obliquely to insertion recesses but has a substantially planar body 59, in the plane inner surface 51 of which the three grooves 55 are formed.
  • the support web 33 and the securing projections 34 are formed as continuous webs.
  • FIGS. 37 and 38 show in cross-section and in a bottom view the connection of two floorboards with the connector 30 after Fig. 36 ,
  • the floorboards have a receiving projection 22, as in Fig. 17 is shown and an engagement projection 25 with two gripping ridges 56 as in Fig. 15 shown.
  • Fig. 38 shows the connector 30 in transparent view. It can be seen that only one engagement projection 25 is used here, which further increases the flexibility of the system arrangement.
