EP4108849B1 - Profile system for forming a terrace floor structure - Google Patents

Description

The invention is based on a profile system for forming a patio floor substructure with the features of the preamble of claim 1. Such a profile system is from FR 3 072 700 A1 known. Another profile system is from the DE 10 2016 000 829 A1 known. A similar profile system is also described by DE 10 2019 132 571 A1 and the DE 20 2015 005 659 U1 .

The known profile systems have the disadvantage that the element for fastening and/or aligning the floor coverings, for example floor tiles, is longitudinally displaceable and thus allows the position of the element to be adjusted in the longitudinal direction of the profiles, for example to compensate for manufacturing tolerances of the floor covering elements in this direction. However, corresponding deviations in the direction perpendicular to the longitudinal direction of the profile struts cannot be compensated for, which is particularly problematic in the case of large-format floor covering elements.

It is therefore the object of the invention to further develop a profile system of the type described above in such a way that it is prepared both in the longitudinal direction of the profile struts and in a direction perpendicular thereto for the compensation of manufacturing tolerances of the floor covering elements which are to be placed on the terrace floor substructure.

This problem is solved by a profile system with the features of claim 1. Advantageous embodiments of the invention are the subject matter of the dependent claims.

Accordingly, in a profile system of the type described at the outset, it is provided that the lower part has three parallel elongated holes which are designed as through holes, with the elongated holes extending in the direction perpendicular to the longitudinal direction of the longitudinal groove and perpendicular to the depth of the longitudinal groove.

Due to the adjustability in the longitudinal direction of the profile struts as well as in the horizontal plane perpendicular thereto, in particular for large, plate-shaped Flooring elements, such as large-format tiles, a calibration of the position of the elements for attachment and / or alignment of the floor coverings for both directions of extension of the floor covering elements are created.

The spacer and the clamping element can in principle, for example, from the DE 10 2016 000 829 A1 be formed known manner.

The upper part and the lower part can be guided in the direction that extends perpendicular to the longitudinal direction of the longitudinal groove and perpendicular to the depth of the longitudinal groove so that they can be displaced relative to one another via a sliding guide in order to enable the element for fastening and/or aligning floor coverings to be displaced according to the invention in the two spatial directions extending perpendicular to one another, in particular in two horizontal spatial directions.

One of the upper part and the lower part can have at least one elongated hole that extends in a direction that extends perpendicular to the longitudinal direction of the longitudinal groove and perpendicular to the depth of the longitudinal groove. The other of the upper part and the lower part can have at least one pin guided in the at least one elongated hole.

The elongated holes can be part of the sliding guide, with the help of which the lower part and the upper part are guided to be displaceable relative to one another.

The upper part can have a pin extending from its side facing the lower part, which is guided in a central one of the three parallel longitudinal holes.

The upper part can have at least two openings, which are in a target orientation of the upper part in relation to the lower part in the direction of rotation about the axis of symmetry of a pin of the upper part, with which the upper part in a central the three slots of the lower part is guided, aligned with the other two, outer slots of the three slots.

In each case one fastening means, preferably a screw, can extend through the openings in the upper part into the respectively aligned elongated hole and thus fix the upper part to the lower part in a rotationally fixed manner in the direction of rotation.

At least one of the fastening means can extend through the upper part and the lower part into a bottom profile side of the longitudinal groove. The fastening means can be a self-tapping screw, for example.

The upper part can have a clamping element for engaging in a lateral groove of a floor covering, from which either at least one pin extends into the middle of the three parallel elongated holes in the lower part, or two parallel pins extend into the two outer ones of the three parallel elongated holes in the lower part.

The at least nine pin can extend through the at least one elongated hole and be supported on the bottom profile side of the longitudinal groove. The length of the at least one pin allows a distance between the clamping element and the bottom profile side to be set. For example, the at least one pin can have a length that is dimensioned such that the clamping element is at a distance from the lower part that corresponds to a vertical distance of a lateral groove of a floor covering from a support side with which the floor covering rests on the terrace floor substructure.

The clamping element can have a through hole which is aligned with the middle of the three elongated holes in the lower part, so that the upper part can be fastened to the lower part and optionally to a bottom profile side of the longitudinal groove using a fastener, preferably a screw, which extends through the upper part and the middle elongated hole and optionally into the bottom profile side. The fastening means can particularly preferably be a self-tapping screw.

The lower part can have a sliding base which is positively received in the longitudinal groove in the direction which extends perpendicular to the longitudinal direction of the longitudinal groove and perpendicular to the depth of the longitudinal groove. In this case, the longitudinal groove can preferably have a U-shaped cross section and thus be designed without an undercut.

The longitudinal groove can be a bottom profile side of the profile strut, which delimits the longitudinal groove on the bottom side. Two parallel, spaced, opposite side walls of the longitudinal groove can extend from the bottom side of the profile in a direction perpendicular to the bottom side of the profile.

The sliding base can bear against the parallel side walls of the longitudinal groove with sliding surfaces on its opposite longitudinal sides. The opposite longitudinal sides can otherwise be designed without contours, so that the sliding base can be displaced in the longitudinal groove essentially without resistance.

According to another aspect, a terrace floor substructure is described that has been formed with a profile system of the type described above. Accordingly, the terrace floor substructure can have the supporting frame for floor coverings formed from profile struts. The profile struts can have a receptacle for a cross connector on at least one of two opposite vertical sides, with the receptacle being designed as an undercut retaining groove or having one in which the cross connector and/or an edge holder is locked.

Instead of screwing the cross connector to the profile strut with the help of several self-tapping screws, it is therefore provided that the cross connector is locked in an undercut groove on one of the opposite vertical sides of the profile strut. The locking can be done without tools due to the undercut of the groove. The cross-connector can be fastened in the undercut groove with a friction fit. For this purpose, the cross-connector can have a sliding block on its side facing the undercut groove, with which the cross-connector is locked in the undercut groove, for example during a 90° rotation after the sliding block has been previously inserted into the undercut groove.

Accordingly, the transverse connector or the edge holder can have a sliding block on a side facing the undercut retaining groove. The sliding block can be rigidly connected to the side facing the undercut retaining groove and can be accommodated in the retaining groove so that it can rotate between a release position and a locking position. The release position and the lock position can change around a 90° rotation about an axis which extends perpendicularly to the vertical side having the undercut groove.

The sliding block can engage behind the retaining groove in the locking position and be arranged completely in line with a clear opening of the undercut retaining groove in the release position.

In the locking position, the sliding block can rest with opposite, short end faces in a frictional connection on opposite inner sides of an undercut of the undercut retaining groove. For this purpose, the short end faces can have a radius or a run-on contour.

The transverse connector can be designed as a retaining shoe open to the upper side of the sub-support frame. The support shoe may have a horizontal bottom side and two side walls extending parallel to one another and perpendicular to the bottom side at opposite edges of the bottom side. The base side and the two side walls extending perpendicularly to the base side can be connected on their sides facing the undercut groove to the side of the cross connector or edge holder facing the undercut retaining groove, in particular extending perpendicular to the side facing the undercut retaining groove.

At least one of the side walls can have an opening for a fastener, preferably for a self-tapping screw, with the opening preferably being in the form of an elongated hole with a horizontal direction of extension. The opening can be used to connect an end of a further profile strut extending perpendicularly to the profile strut to the holding shoe, for example by screwing a self-tapping screw through the slot-shaped opening into the further profile strut. However, screwing the additional profile strut to the retaining shoe, which is open at the top, is optional. For example, it can also be provided that the additional profiled strut is simply inserted into the holding shoe and fixed or clamped there in a frictional connection.

The at least one edge holder can be arranged on the outer circumference of the sub-support frame. At least one spacer can rest with a contact side on the edge holder and have a wall connection with a support surface at an end of the contact side facing away from the edge holder. The The terrace floor substructure according to the invention is therefore also suitable for being attached without tools to any longitudinal position of the profile strut in the manner already described with reference to the cross connector, in order to position a wall connection, for example, to a building wall.

Alternatively or additionally, the terrace floor substructure can have a base holder, which rests with a bearing side on the edge holder and has a fastening means for a panel of a vertical facing of the terrace floor substructure at an end of the bearing side facing away from the edge holder. In one embodiment of the invention, the spacer and the socket holder can be of identical design.

The fastening means for the panels of a vertical facing of the patio floor substructure can be set up to engage over the panels of a vertical facing at their upper longitudinal edge. For this purpose, the fastening means can have a U-shaped receptacle for the panels on its underside facing the upper longitudinal edge of the panels. The fastening means can encompass the longitudinal edge of the panel with the U-shaped receptacle, so that the panel is held in the U-shaped receptacle.

At the end of the support side facing away from the edge holder, the base holder can have a cover strip, which extends in the vertical direction and is designed to cover on the one hand an upper longitudinal edge of a panel of a vertical cover of the terrace floor substructure and on the other hand a free edge of a floor covering lying on the supporting frame.

The subframe can be supported at least on its outer circumference on at least one pedestal. A further fastening means can be fastened to the pedestal, which extends from the pedestal in the direction of the panels and has a further U-shaped receptacle for the panels on its upper side facing the lower longitudinal edge of the panels opposite the upper longitudinal edge. The U-shaped receptacle and the further U-shaped receptacle can be arranged with their openings aligned with one another facing one another.

The support side can have a slot-shaped opening extending in the direction of connection between the wall connection and the undercut retaining groove.

The figure 1 shows an exemplary embodiment of a profile strut 3 in the cross-sectional view. This is designed as a hollow profile with a substantially rectangular cross section. The profile strut 3 can be designed, for example, as an extruded profile and accordingly have a constant cross section over its entire length. figure 2 shows, on the other hand, a profile strut that basically has the same functionality as in figure 1 has shown profile strut 3, but is designed to be more compact in terms of their height in the direction of insertion into the groove 5.

The profile strut 3 has a receptacle 21 for a cross connector (not shown) on its two opposite vertical sides 20 . The receptacle 21 is designed as an undercut retaining groove 24 . The undercut retaining groove 24 has a Undercut 29 on opposite vertical sides. A slot nut can engage behind the undercut 29 in order to lock a transverse connector and/or an edge holder.

A suitable cross-connector 22 is in figure 3 shown. A suitable edge holder 23 is in figure 4 shown. The components 22 , 23 have the sliding block 46 on their side 25 facing the undercut groove 5 . In particular, the sliding block 46 extends from the side 25 and is arranged at end faces 27 spaced from the side 25 to allow the sliding block 46 to engage the undercut 29 . The end faces 27 can be embodied as spherical or circularly contoured friction surfaces, via which the sliding block 46 rests in frictional engagement on the inner sides 28 of the undercut 29 in order to lock the respective component 22, 23 in a locking position in which the sliding block 46 is screwed into the undercut groove 5 in a vertical orientation.

Following the geometry of the undercut groove 5 and the sliding block 46, the locking position and the release position of the sliding block or the respective component 22, 23 are positions rotated by 90° to one another. In particular, the retaining shoe 30 of the connector 22 can be aligned with its clear opening upwards when the cross connector 22 is in the locking position, in which the two end faces 27 of the sliding block 46 are arranged vertically one above the other and accordingly bear against the inner sides 28 of the undercut 29 with a friction fit. In the release position rotated by 90°, the sliding block 46 lies completely in the clear opening 26 of the undercut groove 5, so that the component 22, 23 with its sliding block 46 can be removed from the undercut groove 5.

The profile strut 3 also has a longitudinal groove 5 on its upper side for receiving an element 4 for fastening and/or aligning floor coverings. Exemplary embodiments for an upper part 6 and a lower part 10 of such an element 4 are shown in FIGS figures 5 and 6 shown. The groove 5 has a bottom profile side 15 and parallel opposite side walls 17, the dimensions of the groove 5 being dimensioned such that, for example, in a form-fitting manner, the lower part 10 according to FIG figure 5 can record, so this only in the vertical to the plane of the drawing figure 1 aligned direction within the longitudinal groove 5 is displaceable. On the side facing away from the groove 5 On the outside, the side walls 17 each have a further undercut groove 47 for receiving a sealing element 45 (cf. figure 8 ).

The transverse connector 22 and the edge holder 23 each have a bottom side 31 and side walls 32 which are spaced apart in parallel. However, the two components 22, 23 also differ in particular in terms of their mounting position in relation to a profile strut 3, as is shown, for example, in figure 8 is shown. While the cross connector 22 with its retaining shoe 30 is set up to accommodate a profiled strut 3 or one end of a profiled strut 3, the edge holder 23 serves, for example, to accommodate a spacer 34 (cf. figure 8 ) or a base holder 38 (cf. figure 9 ).

On each of its opposite side walls 32, the transverse connector 22 has a slot-shaped opening 33, which serves as a passage for a fastener, for example a self-tapping screw 14 (cf. figure 8 ) is designed to hold the locking of one end of a profile strut 3 perpendicular to a further profile strut 3, in which the cross connector 22 is suspended via the undercut groove 5. In contrast, the edge holder 23 has a depression 49 on its upper side, in which a support side 35, for example of a spacer 34 or a base holder 38, can be accommodated.

The edge holder 23 has on each of its parallel, opposite side walls 32 an undercut groove open to the outside or a top-hat rail 50 placed thereon. The undercut groove or the fitted top-hat rail 50 can be used to fix a cross-connector, for example the cross-connector 22 according to FIG figure 3 . The undercut groove or the attached top hat rail 50 can be aligned with the undercut retaining groove 24 of a profile strut, so that the same mounting height of the undercut groove or the attached top hat rail 50 and the retaining groove 24 is provided.

figure 5 12 illustrates an exemplary embodiment of a base 10 of an element 4 for fastening and/or aligning floor coverings. The lower part 10 has three parallel elongated holes 12 and is otherwise designed in such a way that it is essentially form-fitting in a groove 5 (cf. figures 1 and 2 ) a profile strut 3 to be included. For this purpose, the lower part 10 has a sliding surface 19 on opposite longitudinal sides 18, via which the Lower part 10 on the side walls 17 of the groove 5 slidably comes to rest. Both the side walls 17 and the sliding surfaces 19 are preferably designed without contours in order to achieve the best possible sliding behavior of the lower part 10 in the groove 5 .

The figure 6 shows an upper part 6, which has a spacer 7. Alternatively, the upper part 6 can also be set up to have a clamping element 8 which is set up to engage in the lateral groove of a floor covering in order to fix the floor covering to the profile system 2 (cf. figure 7 ). The upper part 6 has on its side facing the lower part 10 a pin 13 with which the upper part 6 can engage in the middle of the three grooves 12 of the lower part 10 . The pin 13 and thus the upper part 6 can be displaced along the middle groove 12 . The width of the middle groove 12 can correspond to the diameter of the pin 13 .

Since the grooves 12 and in particular the central groove 12 extend perpendicularly to the longitudinal sides 18 or the sliding surfaces 19 of the lower part 10, along which the lower part 10 can be displaced in the longitudinal direction of the profile 3 in the groove 5, the adjustability of the pin 13 along the central groove 12 means that the upper part 6 can be adjusted in the direction perpendicular to the longitudinal direction of the groove 5 and thus the position of the spacer cross 7 on the upper side of the upper part 6 is adjustable both in the longitudinal direction of the groove and perpendicular to it, for example to be able to react to manufacturing tolerances of large floor covering formats.

In addition, the upper part 6 has a through hole 9 on opposite sides of the pin 13, which is aligned with the two outer elongated holes 12 of the lower part 10 in a clear orientation in the direction of rotation about the longitudinal axis of the pin 13 in relation to the lower part 10, so that an exact positioning of the upper part 6 in relation to the lower part 10 in the direction of rotation is specified. In the flush alignment of the openings 9 with the outer elongated holes 12, fastening means, for example self-tapping screws, can be screwed through the upper part 6, the lower part 10 and into the bottom profile side 15 of the profile strut 3 in order to lock the upper part to the lower part and to fasten the element 4 consisting of the upper part 6 and lower part 10 to the profile 3.

The figure 8 can also be seen that at the top of the profile strut 3 another undercut groove 47 on the opposite longitudinal sides of the Profile strut 3 is designed to accommodate a plug-in seal 45. A spacer 34 is inserted into the depression 49 of the edge holder 23 and is supported with a wall connection 36 via its support surface 37 on a building wall, for example.

The figure 9 finally shows a patio floor substructure 1, in which a profile system 2 of the type described above is supported on a pedestal 200. In particular, the sub-support frame formed from the profile struts 3 has a pedestal bearing 200 at least on its outer circumference, on which the sub-support frame is supported. A further fastening means 42 is fastened to the pedestal bearing 200 and extends from the pedestal bearing 200 in the direction of a panel 100 . The terrace floor substructure 1 also has a base holder 38 which rests on the edge holder 23 with its support side 35 . At the end of the support side facing away from the edge holder 23 , the base holder has a fastening means 39 for a panel 100 of a vertical facing of the terrace floor substructure 1 . The fastening means 39 is set up to engage over the panels 100 at their upper longitudinal edge 101 . For this purpose, the fastening means has a U-shaped receptacle 40 for the panels 100 on its underside facing the upper longitudinal edge 101 of the panels 100 .

The base holder 38 also has, at the end of the support side 35 facing away from the edge holder 23, a cover strip 41 which extends in the vertical direction. The cover strip covers on the one hand an upper longitudinal edge 101 of the panels 100 and on the other hand a free edge of a floor covering (not shown) resting on the supporting frame.

The further fastening means 42 extends from the pedestal bearing 200 in the direction of the panels 100 and has a further receptacle 43 for the panels 100 on its upper side facing the lower longitudinal edge 102 of the panels 100 . The U-shaped receptacle 40 and the further receptacle 43 are aligned with one another and are thus prepared to cover the panels 100 in a vertical orientation in an upper edge of the terrace floor substructure 100 and an underside of the pedestal bearing 200 .

The features of the invention disclosed in the above description and in the drawing can be essential for the realization of the invention, both individually and in any combination, as long as they fall within the scope of the appended claims.
