FINISHING DEVICE FOR FLOORS OR SOIL COATINGS COMPRISING A SECOND SINGLE-PIECE PROFILE

Technical area

The present invention relates to a finishing device for floors or flooring comprising a one-piece profile which is breakable so as to have at least two use functions for floors or floor coverings.

Prior art

In the context of the installation of floating or glued floorings of wood or similar for the dressing of the floors of the habitat, it is necessary to use finishing profiles. Therefore, these operations require the use of different types of wood or similar finish profiles covered with a decorative film to achieve finishes, either between floating floor or glue flooring, or the edges of floor coverings floating or gluing.

It has been proposed so far, finishing sets that are modular and multifunction. For example, in the international patent application WO 2006/074824, there are proposed multifunction finishing sets for floor covering, comprising different modules which are covered by a decorative film, and which are separable, after cutting the decorative film, such so that the finishing assembly is configurable to be used in different finishing functions, and in particular a junction function between two floor coverings, or a stop function or a catch-up function between a floor covering and the floor or other floor covering of different thickness.

More particularly, in an alternative embodiment described in particular in international patent application WO 2006/074824 (FIG. 44), the finishing assembly comprises a unique and modular finishing profile, which comprises two separation grooves, and which is separable. in three separate modules.

A first drawback of this variant with a unique modular finishing profile lies in the fact that in order to make the separation grooves of the module, the manufacturer faces two contradictory use constraints. The separation groove must allow a sufficient mechanical weakening of the profile, to facilitate the separation of the profile into separate modules during its implementation (1st constraint). Conversely, the mechanical rigidity of the two modules separated by a groove must be sufficient so that there is not a collapse of one module relative to the other when the profile is used in a finishing function where the two modules are not separated (for example stop function or level catch function between a floor covering and the floor or another flooring of different thickness). In a disadvantageous way, the manufacturer is obliged to make a compromise between these two constraints, at the risk, for example, of making a groove, which makes it possible to obtain sufficient mechanical rigidity, but which is not sufficiently deep and makes it difficult for operation of separation of the modules, either on the contrary to achieve a too deep groove, which facilitates the operation of separation of the modules, but at the expense of mechanical strength.

A second disadvantage is related to difficulty of industrial realization of the separation grooves of the profile which are narrow and deep.

A third disadvantage is related to the implementation of a cutting tool that must be specific to allow the cutting of the coating.

In order to overcome the aforementioned first drawback, it has been proposed in International Patent Application WO2007 / 116144 to produce a modular finishing profile with added reinforcing shims inserted provisionally into the grooves for separating the profile. This solution, however, does not solve the difficulty of achieving the narrow and deep separation grooves of the profile.
