The technical field
The present invention relates to a compensation profile for floor or wall coverings, as well as to the appropriate method of installation.
The level of technology
When laying the panels, made of wood, such as laminate flooring, etc. due to the inevitable changes in their size due to their swelling and shrinking upon absorption or the return of moisture, it is necessary to provide expansion joints. For example, the panels are placed so that they do not rested tightly against the adjacent wall or the floor, and left a gap for the possibility of extension. On the edge of the slit are usually easy to cover the Board and/or tightly close the elastic filler type silicone. Different is the situation in doorways or in the Central zone. For example, the elongation was possible, despite the impact loads and friction forces, it is proposed in the floor to provide expansion joints at least every 8-12 m Thus, the challenge is, on the one hand, to make compensation seam so that he can better was integrated into the floor in order not to interfere, and on the other hand, to make packing expansion joints as simple as possible.
A well-known system of compensation prof the La consists of two parts and secured in the seam between the opposite edges of two floor or wall panels. For this first element attached to the base, remaining open in the weld area, i.e. to the wall or to the floor, while he fixed dowel connection or glued. Another element of the cover is fixed in this case, for example, by means of a clamping connection on the first element and is designed in such a manner that it covers the surface, finding the top on both panels. This element of the cover has, for example, a T-shaped cross-section.
Due to the fact that the upper covering surface lies on the top of the panels, the element coating is formed above the panel plane, which is undesirable. This not only prevents the visual perception of installed panels, but also forms, in the case of floor coverings, unwanted obstacle, which can be tripped over, and under the covering surface, that is, the panels can easily get wet. In addition, the fastening panel to the base in the seam turns out to be negative, as when the dowel connection, for example, have expensive drilling holes that can cause damage to cables and pipelines, for example, heating of a floor, or sizing, depending on the state of fundamentals, problems of adhesion to the surface, or is difficult to remove the adhesive when you remove floor or wall coverings. Because known the compensation profile is not attached to floor or wall covering, violation of existing fastening leads to unwanted separation of the covering elements from floor or wall coverings, therefore possible, for example, damage to the flooring or laminate.
Disclosure of inventions
Therefore, the present invention is to continue the enhanced compensation profile with improved clamp that its performance is better integrated into the floor or wall covering. An improved method of installation is subject to one independent claim of the invention. Preferred options follow from the dependent claims.
The present invention relates to a compensation profile for installation on the merits between the two opposite, spaced from each other, the edges of the floor or wall panels, in particular floor or wall panels, consisting at least partially of wood materials such as wood fibrous materials medium or high density (hereinafter also referred to as MDF and HDF, respectively), or of shavings. An example of this is the so-called panel laminate. Compensation profile in accordance with the invention has at least two elements of the profile. Floor and wall profiles installed on this be the NII, without the installation of a compensation profile, they form a slit which forms a space for possible longitudinal expansion of the floor or wall panels.
Compensation profile has means for fastening certain elements of the profile to the appropriate floor or wall element. Thus eliminates the need for mounting, for example, to the base of the seam between the floor or wall panels. The basis is not necessary, for example, drilling with a risk of damage to wiring or piping, for instance, floor heating. In addition, there is no need for bonding with the possibility of insufficient clutch and leaving adhesive residue when removing the compensation profile or the entire floor or wall covering. Further, by mounting directly to the floor or wall panels laying the compensation profile is facilitated and accelerated in comparison with the current level of technology. Due to the fact that the compensation profile is installed on the panels, eliminating the risk that in the event of separation of the compensation profile from fundamentals will occur relative offset between the profile and the floor or wall panel - for example, when stepped on the profile, and thus damage to the panel.
The profile is designed so that the above-described arrangement they at least partially movable relative to each other in the direction perpendicular to the edge. Thus is achieved a particularly effective wyravenie compensation profile possible changes in the size of panels of wood-based materials, due to their swelling and shrinking upon absorption or the return of moisture.
Profile in accordance with the invention is used particularly versatile with the ability to prisposoblyaya to the joints of different sizes. There is no need to produce for the various joints of different compensation profiles to provide for each particular size of the seam optimal, then there is not too wide, closing profile.
In a further preferred embodiment, the compensation profile is designed in such a way that it never rises above the opposite sex or the wall surface of the floor or wall panel. This eliminates the presence of edges, which could stumble.
In a further preferred embodiment, the compensation profile is designed in such a way that its surface opposite the base, essentially forms a single plane with the upper sides of the associated floor or wall panels. It should be understood therefore that in the stowed position compensation profile is installed flush with the corresponding panels. The term "PLO the bone" should not be understood literally, on compensation are provided profiles, for example, for reasons of stability, the projections or recesses. Due to such compensation profile, arranged essentially flush, the net transition between the surfaces of floor or wall panels separated from each other by a seam. This avoids the accumulation of dirt and dust on the edges, and thus, an optimum injection profile in a floor or wall covering.
In a further preferred embodiment, the elements of the profiles are connected Rethimno. This provides the ability to lock individual elements independently from each other in a divided state on a separate floor or wall panels and their subsequent connection during installation. This allows stacking particularly quickly.
In a further preferred embodiment, one of the elements of the profile is equipped with a tenon and the other element of the profile is equipped with a groove, and the groove communicates with the thorn to achieve the relative mobility of the elements of the profile. So easily achieved, on the one hand, the possibility of relative displacement of the elements, and on the other side dust-proof connection between the elements.
Means for mounting the elements of the profile to the appropriate floor or Nastia is the number of profiles correspond, according to a further preferred embodiment, fastening means provided on the edges of the floor or wall panels. Thanks to this compatibility means of fastening elements profiles with fasteners panels between a compensation profile can be fastened particularly quickly and simply without additional auxiliary means.
According to a further preferred embodiment means are provided for limiting the displacement of the elements of the profile. Thus prevents the possibility of pull-out elements of the profile are too far from each other during installation. For example, the spike is provided between the elements of the profile for their relative displacement, equipped with a ledge that when removing the thorn from the groove of the other element of the profile meets the stop and thus limits the offset or prevent further running, preventing the cleat from the groove. The means for limiting is performed, for example, in such a way that they limit the possibility of bias, however, when the pulling force, which is significantly higher than the force required for displacement, it is possible to overcome the limiting effects of such funds, for example, by elastic rotation, and thereby to separate the elements of the profile.
In compensation prof the Le according to the invention in a preferred variant of its execution fastening means include at least one groove or tenon. For example, one edge of the panel has a groove, and the opposite edge of the tenon. Then one profile element has one groove for reception of a stud panel. Another element of the profile has a thorn, which communicates with the groove of the panel. Thus, we achieve a very simple connection between the panel and the compensating profile, flush with the panel.
In a further preferred embodiment, the means of attachment, in addition, include fixing elements. Elements for fixing are performed, for example, in the form of grooves and edges-spouts, interacting with them by snapping. This ensures particularly reliable, efficient and protected from the ingress of fluid connection between the panel and the corresponding element of the profile. For example, the groove of the profile element on the lower, i.e. closer to the base side has a protruding bar which is provided with an edge-nose pointing towards the top, that is far from the root side. Last recorded, for example, in the open towards the lower side of the groove, at the bottom surface of the spine panel.
In a further preferred embodiment, the means for attaching the profile to the appropriate floor or wall profiles are designed so that during rotation of the element profile or outdoor or n the wall panel bond is achieved between the profile element and the floor or wall panel. Experience shows that due to this consumption mounting time is reduced by up to 97% compared to the one described in the beginning of the compensation profile, the appropriate level of technology.
Fastening of this type with locking elements, held together by rotation, is known, for example, from the patent EP 1282752 and thus are the subject of this application by reference.
In a further preferred embodiment, the profile consists of wood materials such as MDF or HDF (fibrous material medium or high density). Due to this profile, on the one hand, relatively cheap to manufacture. On the other hand, this makes it quite flexible.
In accordance with a further preferred embodiment of the compensation profile is at least partially made of metal. This is especially durable profile. For example, use aluminum because it is relatively easily handled during installation, and, in addition, due to the relatively small weight easier storage and transportation. In another embodiment, the metal layer is provided only on the side that is farther away from the floor or from the wall, i.e. on the outer side of the profile. Due to this compensation profile in the region, the cat is the ROI come feet, is particularly resistant to wear. In order to prevent slipping on the profile, it can be executed corrugated.
When the method of laying the compensation profile according to the invention in the first stage, a predetermined floor or wall panel connected to the first element of the compensation profile made in accordance with one of the above-described embodiment. In the second stage, the first profile element connects with the second profile element. In the third stage with the second profile element connecting the floor or wall panel. Due to this manner of compensation profile fits particularly quickly. Eliminated time-consuming to mount to the base and the associated further nedostatki, for example, damage in the floor or in the wall of cables and pipelines.
In accordance with another preferred variant of the method according to the invention the first and third stages of the connection is achieved by turning and snapping the locking elements. This allows the installation of a compensation profile with a particularly significant time savings.
Another preferred variant of the method provides that at the intermediate stage, before the completion of the third stage, between the elements of the profile at IU the e partially insert the spacer /spacer/ with topics, in the process of laying temporarily restrict the displacement of the elements of the profile at least in the direction of reducing the distance between them. This is particularly easy to achieve that when mounted between the edges of adjacent floor or wall panels remains a distance sufficient for effective compensation extension by lowering the profile at each other.
The implementation of the invention
The drawing shows a variant of the compensation profile according to the invention in cross section, with two floor panels 3, 4 attached to elements 1, 2 of the profile. The possibility of replacing both elements 1, 2 of the profile is achieved by a groove 6 in the profile element 1 and communicating with the groove of the dowel 5 in item 2 of the profile, and the spike 5 by changing the length of the panel 3 or the panel 4 is in the groove 6, filling remaining in the groove 6 space 11. Spike 5 and the groove 6 provided with interacting with each other protrusions 12, 13 height, for example, 1.5 mm in order to prevent slipping of the spine 5 of the groove 6 when the force required for the displacement. Spike has, for example, a length of 20 mm and a thickness of 2 mm; the groove has a depth of 20 mm For each of the two elements 1, 2 of the profile are attached to the fixing means 7, 8, 10, 11 floor panel. These fastening means suitable fastening means, is the quiet provided between the individual panels. When this spike 8 element profile in cooperation with the groove 7 of the panel is responsible for mounting in a direction perpendicular to the plane of the connection. Element 2 profile performed respectively complementary in shape and has a groove receiving the tenon of the panel 4. Means mounting also include locking means. So, on the bottom, that is converted to the base, the tongue side of the profile element 1, it is equipped with an open bottom groove, which includes, Sedekias upward spout flange 9 on the lower overhanging ledge of the groove 7 of the panel 3. In item 2 of the profile groove element 2 of profile on the bottom, that is adjacent to the base side of the groove has a protruding spout flange directed toward the top, that is far from the Foundation side. Last, Sedekias, includes, for example, in a groove that is open towards the lower side, the lower side of the tenon of the panel 4. Thanks fixation is achieved by fastening elements profile in the plane of the connection, in the direction perpendicular to the edges of the panels. Items 1 and 2 of the profile, each of which in cross section has a length L1=L2=43 mm, on their upper side is designed in such a way that achieves the connection of the panels 3 and 4 flush. This provided for shifting the connection of the groove 6 and the cleat 5 elements 1 and 2 of the profile is located as close as possible to the top of the article is to the parties. For example, the thickness of the upper side of the groove 6 is 1.5 mm, the lower side of the groove 6 has, for example, a thickness of 3 mm when the thickness of the laminate 7 mm, 4 mm when the thickness of the laminate 8 mm and 8 mm when the thickness of the laminate 12 mm
