[0015] Other advantages and characteristics of this invention will be explained in the detailed description below with reference to the associated figures that contain several embodiments of this invention. It should however be understood, that the figure is just used to illustrate the invention and does not limit the scope of protection of the invention.

[0016] FIG. 1 shows a first embodiment of the present invention,

[0017] FIG. 2 shows a second embodiment of the present invention,

[0018] FIG. 3 shows a third embodiment of the present invention and

[0019] FIG. 4 shows a fourth embodiment of the present invention.

DETAILED DESCRIPTION OF THE INVENTION

[0020] FIG. 1 shows a cross section of a profiled rail system 1, comprising a base profiled rail 2, a covering profiled rail 3 and a mounting profiled rail 4. The base profiled rail 2 is mounted by means of non shown mounting means, in particular screws with an underground 5. The base profiled rail 2 comprises mounting means 6, being realised by means of vertically extending webs, being deviated to the interior at the top end. Between holding means 6 a foot 7 of the mounting profiled rail 4 is provided. This foot 7 is made sufficiently broad, to realise a top abutment for the holding means 6 of the mounting profiled rail 4, in order to safely hold the mounting profiled rail 4 on the base profiled rail 2.

[0021] The mounting profiled rail 4 provides a mounting channel 8 for receiving further holding means 9 in form of a screw. These holding means 9 connect the covering profiled rail 3 with the mounting profiled rail 4. By means of more or less deep turning of the holding means 9 a certain height adjustability of the covering profiled rail 3 is realised. The covering profiled rail 3 provides two vertically aligned guiding webs 13. Alternatively only one guiding web 13 can be provided. These guiding webs 13 guide the covering profiled rail 3 during fastening of the holding means 9 and support side forces due to length changes of the floorings.

[0022] The covering profiled rail 3 comprises covering wings 10, overlapping flooring ends 11 of floorings 12. For simplifying mounting of the profiled rail system 1 elastic bodies 20 are provided below the foot 7 and/or laterally to the mounting profiled rail 4. Preferably these elastic bodies 20 are made from a polymer foam, in particular from an elastomer and are by this way mechanically formable, in particular compressable. In the shown unload position the elastic bodies 20 hold the mounting profiled rail 4 in a vertical position, so that the covering wings 10 of the covering profiled rail 3 are aligned about in parallel with the flooring 12. If an external force is applied, the mounting profiled rail 4 can be pivoted with respect to the base profiled rail 2, but the elastic bodies 20 will produce respective restoring forces pushing the mounting profiled rail 4 in the drawn unload position. This facilitates mounting of the profiled rail system 1 very much.

[0023] Additionally the elastic body 20 being laterally positioned to the mounting profiled rail 4 provides a lateral seal of the profiled rail system 1. This seal prevents dust from intruding into the connection between the mounting profiled rail 4 in the base profiled rail 2. Such dust is for example produced during drilling for mounting the base profiled rail 2 to the underground 5. For additionally improving the seal an additional cap like elastic body 20 is provided, laterally and top sided overlapping the mounting profiled rail 4. This elastic body 20 is formed in a way that it can easily be penetrated by the holding means 9. Due to this additionally elastic body 20 the sealing effect and noise damping is enhanced and/or the pivoting angle is enlarged.

[0024] FIG. 2 shows an alternative embodiment of the profiled rail system 1 according to FIG. 1, where like reference numerals entitle like parts. In the following only differences to the embodiment according to FIG. 1 are described.

[0025] The profiled rail system 1 according to FIG. 2 comprises the elastic bodies 20 above the foot 7 of the mounting profiled rail 4. This makes mounting of the mounting profiled rail 4 on the base profiled rail 2 more difficult. On the other hand this embodiment has important improvements. The elastic bodies 20 now press against the foot 7 from top to bottom, hereby providing pre stress of covering wings 10 against flooring 12. By this way the connection between the mounting profiled rail 4 and the base profiled rail 2 can be used for height adjustment of the profiled rail system 1. Additionally the mounting profiled rail 4 will be spaced a part from the base profiled rail 2 even at the bottom, if holding means 2 are sufficiently secured. Hereby the mounting profiled rail 4 will contact the base profiled rail 2 only through the elastic body 20. By this way noise damping is extremely enhanced, as noise cannot be transferred to the base profiled rail 2.

[0026] FIG. 3 shows an alternative embodiment of the profiled rail system 1 according to FIG. 1, where like reference numerals entitle like parts. In the following only differences to the embodiment according to FIG. 1 are described.

[0027] The embodiment according to FIG. 3 provides an elastic body 20 which holds the mounting profiled rail 4 spaced a part from the base profiled rail 2 at all sides. By this way an optimal noise damping is achieved. At the same time an optimal dust sealing is realised, preventing dust or dirt from intruding into the connection between the mounting profiled rail 4 in the base profiled rail 2 for sure. Mounting of the elastic body 20 is relatively difficult in this case. Therefore it is preferred to produce the elastic body 20 together with the base profiled rail 2 as a single piece. By this way the difficult mounting step of the elastic body 20 on the base profiled rail 2 is omitted.

[0028] FIG. 4 shows an alternative embodiment of the profiled rail system 1 according to FIG. 1, where like reference numerals entitle like parts. In the following only differences to the embodiment according to FIG. 1 are described.

[0029] In the embodiment according to FIG. 4 the foot 7 is rounded in a way to preferably achieve a cylindrical or oval surface 14 on its top side. This surface fits to a hollow cylindrical surface 15 of the base profiled rail 2. By this way an extremely low force joint between both parts is realised. Between the base profiled rail 2 and the mounting profiled rail 4 two elastic bodies 20 are provided, each preferably having a cylindrical shape. Alternatively a triangular, squared or rectangular shape is intended. By this way the elastic bodies 20 can be realised by means of simple cords, especially rubber cords. The elastic bodies 20 are provided in recesses 16 of the base profiled rail 2 and the mounting profiled rail 4. By this way the elastic bodies 20 are securely held in reception bowls, hereby preventing any displacement of the elastic bodies 20 from their seat.

[0030] It is intended to combine the shown and described embodiments in any combination. For example the embodiment according to FIG. 4 can be provided with a cap like elastic body 20 according to FIG. 1.

[0031] Since some of the embodiments of this invention are not shown or described, it should be understood that a great number of changes and modifications of these embodiments is conceivable without departing from the rationale and scope of protection of the invention as defined by the claims.
