Description

The invention relates to a bridging profile, in particular made of wood with height compensation Flooring elements.

When laying conventional floor coverings (parquet, laminate, tiles, etc.) large areas can be rasterized using so-called expansion joints. Furthermore are Corresponding bridging profiles at transitions of different heights required.

Previously common aluminum profile systems consist of a base that can be attached to the floor profiles on which corresponding cover profiles are attached, where necessary, adjustable in height (see e.g. EP 0 696 667 A1).

Such profile systems are due to the complex profiles and in terms of used materials very expensive. In addition, aesthetic requirements especially with real wood flooring or laminate flooring.

The bridging profiles made of wood known from DE 296 19 550 U1 with the additional provided height compensation elements in the form of rubber-elastic parts can largely meet the above requirements. The height compensation elements provided there enable a good support of the, even with different heights of the floor structures Profile strips on the bare floor. A good circulation is especially for wooden profiles absolutely necessary, otherwise it is easy to tear / split when they are attached the transition points from the base part and cover profile.

However, the height compensation elements described in DE 296 19 550 U1 require for different heights of the floor structures each a corresponding separate compensation element. In addition, the attachment of the compensating elements on the base part is only through additional grooves possible.

The invention has for its object such a one-piece bridging profile to provide with height compensation elements, in which a simple Attachment of the height compensation elements to the base part without additional auxiliary devices is possible. Furthermore, an adaptation to the different heights of the floor coverings with a reduced number of such elements.  

This task is accomplished through a one-piece bridging profile with height compensation elements ten with the features of claim 1 and the independent claims 2 and 3 solved.

Further advantageous developments can be found in the features of the subclaims.

The one-piece bridging profile according to the invention with height compensation elements is easy and inexpensive to manufacture, because the bridging profile in a standard size and can be manufactured without additional holding devices. The height compensation happens here by height compensation elements, which are able to with the preferred Variants to compensate for at least two different height differences and thus leads to a reduction of such elements.

The invention is explained in more detail with reference to drawings.

Fig. 5: Sketch of an assembled known transition profile using a U-shaped height compensation element

Figs. 1 and 2 show a U-shaped leveling element (3) consisting of the base surface (4) and substantially perpendicular resilient legs (5, 5 '). Here, in FIG. 1 can be seen that each leg surface (5, 5 ') has a side facing away from the base surface (4) side U-shaped recess has, so that each of the webs (11, 11', 12, 12 ') of the respective Leg surfaces ( 5 , 5 ') remain. The sections ( 1 ) of the bridging profiles are thus either on the base surface ( 4 ) or the surfaces ( 13 , 13 ').

In the height adjustment element (3) of FIG. 2 can be realized, the different heights on the one hand by the thickness (14) of the base surface (4) and the other by the thickness (20) of the leg portion (10, 10 '). The ( 9 , 9 ') designates the U-shaped recesses in the leg surfaces ( 5 , 5 ') extending from the base surface ( 4 ). This profile can be clamped onto the section ( 1 ) of the bridging profile by appropriate turning and turning.

In. Fig. 3 shows an alternative modified embodiment of the U-shaped height compensation profile. In the H-shaped profile shown there with its pairs of leg surfaces ( 5 , 5 'and 8 , 8 ') projecting on both sides from the base surface ( 4 ) with different heights, two different height adjustments can be made with one profile.

As a result, the number of height compensation elements can be different Floor coverings can be significantly reduced.

FIGS. 4 and 5 show a known U-shaped leveling element (3) consisting of the base surface (4) and substantially perpendicular resilient legs (5, 5 '). The leg surface 5 'running at an angle α ( 6 ) <90 ° in the unmounted state can be seen in particular in FIG. 4. The outwardly curved leg surfaces 5 , 5 'show the height compensation element ( 3 ) clamped onto the bridging profile - consisting of the section ( 1 ) and the cover section ( 2 ). In the base surface ( 4 ), the openings / recesses ( 7 ) are made in the center, which have a slightly larger cross section than the fastening elements (screws), not shown, and thus problem-free clamping of the U-shaped height compensation elements ( 3 ) in the area of the bores in Enable bridging profile. If there are no openings / recesses ( 7 ) in the height compensation elements, these should preferably be provided on both sides next to the bridging profile bores in order to ensure a good support of the profiles. To compensate for different heights of the floor coverings, U-shaped height compensation elements ( 3 ) with different heights of the base surfaces ( 4 ) are provided.

The height compensation elements described can be made from a wide variety of materials be made.

For example, from metals such as aluminum, steel, etc. or plastics (thermo plastics or thermosets) such as polyolefins (PE, PP), PVC, ABS, etc. As a manufacturing process all known methods are conceivable; with plastics calendering / extruding of corresponding profiles and separating the endless profiles as well as injection molding processes. The Metals are shaped accordingly by stamping / bending processes.

Due to the bridging profile / height compensation / fastening system according to the invention it is possible to offer a system with standardized bridging profiles under Use of the variable height compensation elements practically all occur in practice coped with the height differences in the usual floor coverings.
