Description

Section bar track system

Technical Field

The invention relates to a rail system, in particular to a profile rail system.

Background

In practice, many profile rail systems are known, which differ in particular in the manner of installation. In particular, profile rail systems of this type are known which are formed from a base profile which is fixed, for example, in a joint. A cover profile is fastened to the base profile by means of a spring clamp or a screw connection. The cover profile has at least one cover flap which covers the edge of the floor covering. Nevertheless, it is ensured that the floor covering can be moved horizontally in order to move disruptive forces away from the floor covering. The principle of floating installation is thereby maintained by the profile rail system.

For example, US6345480B1 discloses a profile rail system. The profile rail system is designed to be formed by a base profile which is fixed, for example, at a joint. The cover profile is fixed to this base profile by clamping. This cover profile has a cover flap which covers around the floor covering. This ensures that the floor covering is covered around and in the connection. Horizontal movement of the floor covering can be ensured to isolate the floor covering from destructive forces.

The profile rail system according to claim 1 is used for bridging a floor covering transition, end section or a step. The profile rail system is essentially formed by a cover profile, for which a base profile is optionally provided. The cover profile can also be integrally connected to the base profile. In particular, it is also conceivable for the cover profile to have no covering function at all and to be invisible in the installed position of the profile rail system. The base profile is usually fixed directly to the base plate. Different methods can be used for this. For example, the base profile can be screwed or glued to the base plate. Alternatively, the base profile can also be gripped with a tab under the floor covering, so that a clamping handle can be formed together with the cover profile. If appropriate, a connecting element can be provided between the base profile and the cover profile, by means of which additional adaptation to different thicknesses of the floor covering is possible. In order to cover the edge of the floor covering with the profile rail system, it has at least one covering flap. The cover flap is resiliently pressed against the floor covering. In this way, a sufficient contact of the covering flaps on the floor covering element is ensured, and the profile rail system does not loosen during the pedaling of the load. In addition, the elastic covering flaps have the advantage, in particular, that, in the case of a connection underneath the covering flaps, for example, cables or the like can also be laid afterwards. For this purpose, the covering flap is simply lifted against the force of the at least one spring and the cable is laid. The cover flaps are then swung back into the covering position, thus covering the joint. It is essentially immaterial whether the entire covering profile or just its covering flaps can be adjusted or whether it is elastically pretensioned. In either case, the desired effect is achieved so that the skilled person can select a suitable configuration for each particular application. In particular, to simplify the checking operation, at least one of the springs is bistable. In this case, it is conceivable, in particular, for the covering flap or the covering profile to be pressed by at least one spring into a covering position, in which the covering flap is pressed against the floor covering, on the one hand, and into an upwardly moved installation position, on the other hand. Between the two positions, a dead point is provided which must be overcome in order to be able to always take up the other position. This measure also simplifies the installation of the profile rail system, since the cover flap or the cover profile can be held in the installed position during installation without it having to be locked separately for this purpose. In addition, the cover flaps also allow a good locking of the floor, which is laid floating, without further fixing measures being required.

It is also advantageous according to claim 2 if the cover flap is held pivotably on the cover profile by means of a pivot if only the cover flap is moved. The at least one spring in this case acts on the covering flap in the pivoting direction such that the free end of the covering flap presses against the floor covering. The pivot bearing is preferably designed such that it has an extrudable shape. In this way, the cover profile and the cover flap can be produced particularly simply and therefore cost-effectively. This design of the cover profile has the particular advantage, in particular for cover profiles with two cover wings, that the two cover wings press against the respective floor covering independently of one another by spring force. In this way, different cover heights can be compensated automatically and without separate correction and adaptation measures. Furthermore, in order to insert a cable at a later point in time, for example, into a joint in which the profile rail system is fixed, it is sufficient to turn only one covering flap upward at a time, while the other covering flap remains in its covering position. The subsequent checking work is therefore particularly simple.

Alternatively or additionally, the cover profile is held so as to be movable upward relative to the base profile. This configuration is preferred in particular in the case of a cladding profile with a single-sided cladding flap, since in this case no separate height adjustment of this single cladding flap is necessary.

In particular, it is conceivable to connect the cover profile with at least one cover flap before the fastening of the base profile, so that the entire profile rail system can be installed in the joint. In the installed position of the at least one covering flap, the assembly is unobstructed. This eliminates complex assembly of the individual profiles on the construction site. According to claim 4, it is advantageous if the covering profile or the covering flap can be moved between a covering position pressed with pretensioning force onto the floor covering and a mounting position releasing the space under the covering flap.

In particular in the case of a pivoting support of the covering flaps, it is advantageous according to claim 5 if the at least one spring acts on the at least one covering flap on the one hand and on the covering profile on the other hand. In this way, it is achieved that the spring action always has the same effect irrespective of the height adjustability of the cover profile.

A preferred development of the profile rail system is given by the technical solution 6. The spring engages in a groove of the cover profile and is held therein sufficiently securely. At least one of the grooves is oriented at an acute angle to the plane of the floor covering, so that the spring can be inserted into the groove at different depths depending on the pivot angle of the covering web. In this way, a simple dead point covering the flap rotation can be achieved. In particular, it is conceivable to configure the groove such that the spring engages deeper into the groove in the installation position than in the covering position. In this case, a further advantageous additional effect is achieved in that the pressing force of the covering flaps against the floor covering is greater than the pressing force against the stop in the installed position.

Further according to claim 7 it is advantageous when the groove is spaced from the pivot bearing. In this way, an increased adjustment travel of the spring is obtained during pivoting of the covering flap, which results in a corresponding increase in the spring tension and thus in a greater contact pressure of the covering flap on the floor covering.

As an alternative, in order to realize the profile rail system as simply as possible, it is advantageous according to claim 8 when the groove provided on the covering flap is shaped in the pivot bearing for at least one covering flap. In this way, a particularly compact cover profile structure is obtained.

In particular for cover profiles that can be adjusted in height, it is advantageous according to solution 9 if the at least one spring acts on the cover profile on the one hand and on the base profile or on a separate connecting piece on the other hand. In this way, the at least one spring easily pulls the covering profile towards the base profile to press the at least one covering flap towards the floor covering.

According to the solution 10, the desired dead point can be achieved particularly effectively by providing at least one runner on the base profile, on the cover profile and/or on the cover flap. The sliding groove is contacted by at least one key, and the key is axially and elastically pre-tensioned. In this way, the desired force action can be easily set by means of the slide groove. The cover flap or the cover profile is thereby held in the installed position, the slide groove in at least one region not exerting an adjusting force on the push button. This can be achieved, for example, by a stop or the like.

In order to achieve a symmetrical force distribution, it is advantageous according to claim 11 if at least two runners are arranged pointing towards one another. Between these two runners, a push button is arranged, which in this case is axially retractable and the two runners are in contact.

A simple alternative embodiment of the bistable spring is given in claim 12. The at least one spring is formed by a leaf spring bent transversely to the bending direction. Such a leaf spring has two stable shapes, between which a dead point is provided. The two stable shapes of the leaf spring are selected in such a way that the covering position and the installation position are arranged within these two stable positions but on both sides of the dead center.

In order to achieve versatility of the profile rail system, it is advantageous according to claim 13 when the cover profile maintains additional height adjustability and/or turnability relative to the base profile.

Finally, according to claim 14, it is advantageous if at least two covering flaps are provided, which overlap at least in the covering position. The two cover flaps are preferably pivotable relative to one another, wherein the cover flaps are fastened to the cover profile, which no longer has a covering function. In this way, only the cover flaps are visible from above in the covering position, so that the surface shaping of the cover profile can be carried out in any desired manner. This simplifies the support of the cover profile in particular, since the cover profile can be used for different base plates.

Detailed Description

The profile rail system 1 according to fig. 1 comprises a base profile 2 and a cover profile 3. In the present exemplary embodiment, a connecting element 4 is also provided between the two profiles 2, 3, which element serves to hold the cover profile 3 securely on the base profile 2.

The base profile 2 is substantially L-shaped and has horizontal transverse legs 5 and vertical longitudinal legs 6. The cross leg 5 is provided with a row of holes 7 for receiving a screw not shown. The base profile 2 can be easily fixed to the base using these screws. In particular, it is conceivable to press the screw directly into the base or, in particular in the case of mineral bases, to use a dowel as the connecting element.

As a further alternative, the base profile 2 can also be adhesively bonded to the base. For this purpose, the transverse leg 5 has a row of grooves 8, which can be filled with adhesive. In this way, a particularly reliable adhesive connection to the base is achieved. The longitudinal leg 6 is provided in the upper region with a corrugated surface 9 for the snap-in height adjustment of the cover profile 3.

On the longitudinal leg 6, a connecting piece 4 is fitted, which has an inner contour 10 adapted to the corrugated surface 9. The connecting piece 4 can thereby be adjusted with respect to the base profile 2 by a defined number of corrugations. This form of adjustment is particularly useful for adapting to different floor covering thicknesses. The connecting piece 4 has in its upper region a cylindrical outer contour 11, which establishes a connection with the cover profile 3.

The cover profile 3 has an inner contour 12 which is adapted to the outer contour 11 of the connecting piece 4. The inner contour 12 is formed by two partial cylindrical contours lying one above the other. The profiles 11, 12 allow the covering profile 3 to be placed over the connecting piece 4 at two different heights, thereby also enabling a further height adjustment.

A pivot bearing 13 is provided on the cover profile 3, which pivotably receives a cover flap 14. The cover flap 14 overlaps the floor covering end 15 and lies substantially over the floor covering 16. The pivot bearing 13 is formed laterally by an arm 17 which projects beyond the covering profile 3 and at the end of which a cylindrical inner bearing shell 18 is arranged. The cylindrical bearing shell 18 is captured by a cylindrical inner contour 19 that covers the wing plate 14. In addition, a cylindrical inner contour 20 is formed in the cover profile 3, which is part of an outer bearing shell 21. It is possible or not that the respective covering flap 14 is supported sufficiently securely by the two bearing shells 18, 21, so that the covering flap 14 engages the pivot bearing 13 by more than 180 ° to achieve a secure support.

Furthermore, a groove 22 is formed in the inner bearing shell 18, which receives at least one leaf spring 23. In the case of long profile rails, it is conceivable to distribute several leaf springs 23 over their length in order to achieve a uniform pivoting force. The leaf spring 23 is clamped at its opposite end in a further groove 24 covering the flap 14. The grooves 22 of the bearing shoes 18 are arranged at a sharp angle to the planar extension of the floor covering 16, so that the springs 23 can engage into the grooves 22 at different depths depending on the pivoting position of the covering flaps 14. In this way, dead centers are achieved which have to be overcome in order to transfer the cover flap 14 from the illustrated cover position into the installation position according to fig. 2.

Fig. 2 shows the profile rail system 1 according to fig. 1 in the installed position. It can be seen here that at least one spring 23 is pressed quite deeply into the groove 22, whereby the force direction of the spring 23 is rotated. In this position, the cover flap 14 is pressed upwards by the force of the spring 23 until it abuts against the stop formed by the arm 17. In this position, for example, the conductor can be laid very simply in the free space below the cover flap 14. It is also conceivable to fasten the base profile 2 to the base plate in this position, since the screw, not shown, is freely accessible in this position.

Fig. 3 shows an alternative embodiment of the profile rail system according to fig. 1, wherein like reference numerals designate like parts. The main difference to the profile rail system 1 according to fig. 1 is that the cover profile 3 has two cover flaps 14. For this reason, the covering profile 3 therefore has two pivot bearings 13 and a spring 23 for the two covering wings 14.

The profiles 11, 12 allow a limited oscillation of the covering profile 3 with respect to the base profile 2. In addition, the cover profile 3 is placed over the connecting elements 4 at two different heights in order to allow further height adjustment.

Fig. 4 shows an alternative embodiment of the profile rail system according to fig. 1, wherein like reference numerals also designate like parts. In this embodiment, at least one cover flap 14 is fixedly connected to the cover profile 3. In this case, instead of the pivotable construction of the cover flaps 14, the entire cover profile 3 is connected to the base profile 2 in a highly adjustable manner.

In order to achieve the desired spring action, a mechanism is provided in the longitudinal leg 6 of the base profile 2, which mechanism is explained in more detail below with reference to fig. 5.

The longitudinal leg 6 according to fig. 5 has a sliding groove 25 on the inside, which is self-centering. The sliding groove 25 is arranged at an acute angle to the direction of movement 26 over almost the entire length and converts the horizontal force of the button 27 into a vertical pulling force, which pulls the cover profile 3 downward. Only in the upper end region 28 is the guide groove 25 oriented parallel to the direction of movement 26, so that the push button 27 does not exert a vertical force on the cover profile 3 in this region. Accordingly, in this upper end region 28, the position of the cover profile 3 is stable, while in all other positions the cover profile 3 is pulled towards the floor covering 16 to cover the legs 14.

The push button 27 comprises a tube 29 in which a helical spring 23 is held. The helical spring 23 presses the two key heads 31 axially outward, whereby the keys 27 exert an axial force on the sliding grooves 25. This axial force is converted by the inclination of the slide groove 25 into the desired vertical adjustment force of the cover profile 3.

Fig. 6 and 7 show the profile rail system 1 according to fig. 4 and 5 in the installed position. The push button 27 is located in an upper end region 28 of the slide groove 25, in which region it is held in a stable position. In this position, the cover profile connected to the push button 27 is moved far upwards and can also be pivoted about the push button 27 as a pivot axis. This simplifies access to the free space under the cover flap 14.

Fig. 8 shows a further alternative embodiment of the profile rail system 1, wherein like reference numerals also designate like parts. The design of the profile rail system 1 is a further variant of the profile rail system 1 according to fig. 3, in which only the differences are mentioned.

In this embodiment, the cover profile 3 is connected integrally to the base profile 2, wherein the profile 3 no longer assumes the protective function of the cover connection. More precisely, the covering tab is completely borne by the two covering wings 14. For this purpose, the cover legs 14 overlap in the shown cover position. This overlapping is achieved by two slightly inclined portions 32 covering the mutually facing end faces of the wings 14.

In order to be able to pivot the cover flaps in the covering position, despite their mutual covering, the pivot bearings 13 of the two cover flaps 14 are offset downwards by means of the webs 33. By this measure, it is also possible to cover the pivot bearing 13 with the cover leg 14, so that in the shown covering position the covering profile 3 is not visible from above. The inclined portion 32 is preferably tangential to the axis of one of the two pivot bearings 13.

Furthermore, a groove 22 is formed on the web 33, which receives the spring 23. The groove 22 is spaced apart from the pivot bearing 13 in order to achieve a greater adjustment travel for the spring 23 in this way. The opposite ends of the spring 23 are clamped in the grooves 24 of the cover profile 3. The groove 24 is inclined downward in this case in order to correspondingly preload the spring 23. This measure increases the spring force in the covering position, so that the covering flap 14 presses correspondingly more tightly against the floor covering 16.

Fig. 9 finally shows an alternative embodiment of the profile rail system 1. The structure thereof corresponds essentially to the profile rail system 1 according to fig. 8, only the differences being mentioned below. The profile rail system 1 according to fig. 9 comprises a base profile 2 and a cover profile 3 formed as separate components. The covering profile 3 is held in the base profile 2 in a highly adjustable manner, wherein the two parts are locked to each other by the corrugated surface 9 of the longitudinal leg 6. The covering profile 3 has a pivot bearing 13, in which a covering web 14 is pivotably supported. In addition, a fixed cover flap 34 is formed on the cover profile 3, which overlaps the pivotable cover flap 14.
