Floor covering section with locking device

0001The invention relates to a floor covering or wall covering, consisting of several, a cross-dressing forming individual profiles, wherein between adjacent sections is provided a tongue and groove.

0002Floor coverings of wood or plastic composed of individual profiles, which over or when laying the floor covering in the region of their longitudinal edges engaging each other and thus form a cross-dressing. Only in If necessary, these are wood or laminate floors laid with the underground connected, usually the floor coverings are laid floating. There are Proposals as a solid and high stress was entertaining Floor covering to be achieved, whereby it is of particular importance that this composed of individual profiles covering slightly verleg- or mountable. Thus, DE-OS 1918203 a plate for floors, walls or the like are known, a dovetailed with the tongues and grooves own cross-section, wherein the respective plates to Assembling adjacent profiles need to be pushed into each other, what proved to be impractical due to the space required for this Has. The preparation of such profiles is far too expensive, since too exact Adjustment of the interlocking components is required. From DE-OS 198379 77 is a floor covering is known which a simple tongue and groove which are introduced into the region of sizing agent, which in the Together-hang with a matched to the color of the profiles sizing agents a connection between the adjacent profiles to be achieved. The Installation of such flooring is however the substantial disadvantage connected, that the application of the sizing agent a further expensive represents step, especially since the use of sizing agents always to the disadvantage accompanied by Ver-contamination of the floor covering.

0003Against this background, the present invention, the object, to create a floor or wall covering which with little effort must be mounted and a durable rugged cross bracing between the profiles allows.

0004This object is achieved by the fact that in the tongue and groove a catch is provided.

0005When laying the flooring or wall covering is a tongue and groove prepared which additionally secured by a catch connection is. Adjacent sections are so set inside each other so that a predetermined Locking resistance must be overcome, said with little installation effort can produce an optimal connection between the profiles. At the same time, the profiles are aligned exactly in the prescribed manner positioned to each other.

0006It is expedient if the catch by at least one Projection and a correspondingly formed on this projection Recess is formed. To this end, a profile that, thanks to the invention Education can also have a particularly great length, on one longitudinal side a groove and on the other a spring. Furthermore, a on one side Projection and at the other a recess provided whereby the Nesting tongue and groove a particularly intimate locking connection can be achieved. It is understood that the latching means quite a game should be designed belassend, especially too exact production of the latching means would entail unacceptable cost in manufacturing.

0007It is particularly contemplated that the projection of the pen and the recess of the groove is associated with. In addition to manufacturing aspects speaks for this is that the nesting of the tongue and groove in this way is easier. In connection with the resilient material of wood or Plastic is the overcoming of the assembly to force corresponding low. It is understood that projection and recess be formed can that the locking connection also be nondestructively released again can. Otherwise, the locking connection may also be designed so but that just no later disassembly of adjacent profiles is possible.

0008In addition, it is proposed that the projection on the bottom the spring and the recess on the upper side of the lower leg of the groove is arranged. The compound has, as mentioned, the advantage that in the context of Dimensions and design of the profiles can be defined as adjacent Profiles are arranged to each other. With appropriate positioning by projection or recess, this results in that a release of the Locking connection with the respective leaving the necessary for this game is made possible. This is for example the case when a clip connection is established between tongue and groove in the mold, that the latching connection in the Range from the lower edge of the spring and the upper edge of the lower leg of the is groove provided.

0009In addition, it is also conceivable that a further projection on the Top of the spring is arranged so that in consequence a double latching in connection with the resilient material wood or plastic a particularly stable connection is given.

0010In regard to the shape of the projection, it is proposed that the Projection has the shape of a polygon. It is understood that the Protrusion in particular must have a sufficient depth to provide a stable to can form latching connection, wherein which prevents the could cancel projection.

0011This is for example the case if the projection is in the form of a Trapezium with blunt extending angles. The corresponding to the Projection recess formed should this triangular roughly the necessary clearance when assembling the profiles be belassend formed, so that the projection of the recess well adapts. The trapezoid has a Shape in which the projection at an angle of approximately 130 to 140 ° angled runs, as seen from the lower edge of the spring, whereupon a running parallel to the lower edge portion is connected.

0012A further advantageous embodiment of the invention provides the Locking connection by the spring associated projection and a Furthermore, to form the groove associated projection. This is almost double created latching connection, namely by a first pair Projection / recess and another behind it disposed pair, wherein the Assignment to the groove or spring is reversed. This forms in the area between the projection / recess pair an advantageous locking edge.

0013The other advantage should it at an angle of about 45 ° to profile be arranged, the protrusion is located in the region of the inside of the lower leg of the groove, partly on the long side of the profile and partially on the upper side of the lower leg. Instead of an edge in this area is the profile there rounded designed to improve the locking, wherein having the corresponding thereto further recess edge or also may be rounded.

0014From the arrangement of two staggered arranged couples Projection / recess arises that between the projections joint locking edge is provided. The forming the actual latching Locking edge is the common edge of the projection / recess pairs, so here the projection with its back to the recess bears, wherein a result of the arrangement of the locking edge at an angle of approximately 45 ° particularly favorable locking is effected. The locking edge causes the Nesting of adjacent profiles that for preparing the compound A Sliding from the projection in the recess takes place.

0015Furthermore, it is provided that the locking connection in the region Tread arranged a gap between the adjacent profiles yielding is. On the upper side of the floor covering thus remains between adjacent Profiles a narrow gap, the result of the advantageous uniform arrangement the profile also affects visually appealing, because the invention with the Making profiles and the connection by cliffs improved connection leaves. This not only ensures that actually between adjacent Profiles in general an effective connection exists, but it is also specified where these sets, so that much more precise, but also easier can work. In addition to advantages in the assembly, so the nesting adjacent profiles is the fact that the assembly of the gap, the possibility of movement enables between two adjacent sections, when the Locking connection to be established between these or dissolved later. In this case, the spring having the profile part in the direction of the gap slightly raised, whereby the projection is pushed into the recess bwz. can be drawn from this.

0016With respect to the shock is suggested that a front of the projection Bearing surface is provided, in whose region the spring with its lower side the upper side of the lower leg of the groove lies, whereby an even better Transmission of forces is reached and a cancel of the projection or the Spring is prevented.

0017The invention is particularly characterized in that a Flooring or a wall covering made of wood, imitation wood or plastic is created, which consists of individual profiles which on in the assembly particularly simple, precise, uniform and stable, lasting way together can be connected. Adjacent profiles have to not only a tongue and groove on, but in addition each other latching formed so that an even years later permanently loadable Connection is established which or without additional connecting means such as adhesive Fixation can get along on the ground, because a beneficial stable cross composite is created between the individual profiles. The accuracy is added, lie with the adjacent profiles to each other because of the manufacture Latching connection at the same time positioning the profile results to each other. In order the production of particularly long profiles possible. Also source or consumption processes can well through this intimate connection between the profiles be included and where necessary a replacement of individual or multiple profiles easily possible.

0018Further details and advantages of the subject invention result a from the following description of the accompanying drawing, in which preferred embodiment with the necessary details and illustrated items. Show it:<dl tsize="12" compact="compact"><dt>Fig. 1 and 2</dt><dd>a locking connection</dd><dt>Fig. 3</dt><dd>registered with pen and</dd><dt>Fig. 4</dt><dd>a profile with groove.</dd></dl>

0019Fig. 1 is designed as a tongue and groove locking 4 5 between the adjacent sections 2 and 3. A plurality of such profiles 2, 3 forming a floor covering 1 or a wall covering made of wood, imitation wood or Plastic. The locking connection 5 is formed by the profile 2 assigned Spring 8 and the profile 3 associated groove. 9

0020In contrast, FIG. 2 shows such a latching connection 5 in more detail Representation. It can be seen that the profile 3 with the spring 8 at its Underside 13 has a projection 6, which corresponding to a Recess 7 having at the top 14 of the lower leg 15 of the groove. 9 Viewed in the direction of impact is behind the profile 3 associated projection 6 a recess to detect 19 which corresponding to the projection 12 of the profile 2 is formed. This causes a locking edge 11, which between them each pair of projection 6 / recess 7 and projection 12 / recess 19 sets and in the region of both profiles 2, 3 abut. also is a bearing surface 18 can be seen at the top of the spring 8, in the region is also where contact between the profiles 2; 3. Evident are further the gap 16 between the profiles 2, 3 in the area of ​​the tread 25. This gap 16 is for all of the adjacent profiles at identical position and also of constant width, as it were, the clip connection between the profiles this distance pretending. The depth of the groove 9 exceeds that of the spring 8, so that between the tip 26 of the tongue and the groove bottom 21 a distance remains. To produce the locking during assembly of the floor profiles is the right Profile 3 with the spring 8 in the left profile 2 and the groove 9 is pushed. Here, the right-hand section 3 can be raised at a slight angle with the spring 8 are inserted into the groove, so that for producing the locking connection 5 can be reduced to be overcome forces. In the area of ​​the longitudinal edges 24 on the ground 22, the profiles 2 and 3 abut each other.

0021Fig. 3 shows a profile 3 to the on the bottom 13 of the spring 8 arranged projection 6. This is trapezoidal in shape, ie, the two Legs 27, 28 extend in the shape of obtuse angles to the bottom 13 the spring, in between is a parallel to the bottom 13 extending section 23 to recognize. The inner leg 28 also forms the locking edge 11. At the Projection 6 closes the recess 19, which correspond to a corresponding projection is formed in the region of the adjacent profile. At the top 17 of the spring 8 a further projection could be located, with in conjunction with the resilient material of wood or plastic a particularly intimate locking could be achieved.

0022Fig. 4 shows a profile 2 with groove 9 and a right angle in such descriptive recess 7, which the rounded protrusion formed 12 downstream. It is understood that further chamfers 20 in such Filters are arranged, which in particular for the handling in the preparation of the locking connection are beneficial.
