Description

DESCRIPTION

Panel fastening system

The invention relates to a method for the manufacture of a floatingly mounted ceiling or wall covering according to claim 1. The invention also relates to a corresponding wall or ceiling covering according to claim 7 and to a system mounting bracket for the manufacture of a floatingly installed wall or ceiling covering according to claim 13. From documents FR2750462A1, US2013 / 000238A1, US2006 / 156664A1, US4558584A and US4934119A, for example, fixing systems are known for wall and ceiling coverings. All these wall or ceiling coverings are arranged against each other using the classic tongue and groove profiles or half-wood assemblies and are fixed with mounting clips on a substructure or directly on the respective wall or ceiling.

From EP1343943B1, for example, wall and ceiling coverings with at least partially floating installation are known. This document discloses panels joined by corresponding locking profiles and fixed by a clip housing on one of the panels and a clip on the substructure. EP2454425A2 shows a mounting system for a wall and ceiling cladding completely installed in a floating way and formed by panels that are joined by corresponding locking profiles.

EP2454425A2 discloses the characteristics of the preamble of claims 1 and 7.

The clip is arranged in the clip housing such that the panel can be moved in the clip both transverse to the longitudinal axis direction and in the longitudinal axis direction of the panel. In this sense, the possibility of movement transverse to the direction of the longitudinal axis of the panel is created by a clip housing in the panel, which is longer compared to the clip length. However, movement transverse to the direction of the longitudinal axis is possible only in a very limited way, because the space available in the clip housing is very limited. It is also difficult to secure panels arranged on walls and ceilings and attached with corresponding locking profiles, because accidentally separating a panel produces a domino effect that causes large sections of the panel surface or even the entire panel surface to fall off. wall or ceiling mounted.

Therefore, the invention has the objective of providing an improved method and an improved mounting system for the manufacture of a floating or wall cladding or ceiling that allow to manufacture a wall or ceiling cladding protected against accidental separation. The objective is also to provide a corresponding wall or ceiling covering.

The invention achieves the object by means of a method with the characteristics of claim 1, a wall or ceiling covering with the characteristics of claim 7 and a mounting system with the characteristics of claim 13.

The method according to the invention for the manufacture of an at least partially floatably mounted ceiling or wall cladding, comprising a panel surface with a plurality of panels that are joined together on the longitudinal sides and / or the transverse sides by locking profiles that are in correspondence with each other and can be attached without adhesive, it presents the steps: arranging the first panels of a first row of panels on structural rails by means of a mounting clip, the mounting clip being mounted on the structural rail in a mobile way in the direction of the structural rail and engaging the mounting clip with a housing in a recess in the first panels, so that the first panels are mounted in the housing movably transverse to the direction of the structural rails, and join second panels from a second row of panels to the first panels using longitudinal locking profiles s, being provided before, during or after the union of the first and the second panels a safety element against fall that prevents the accidental separation of the panels from the structural rail.

The method according to the invention enables particularly easy and tool-free mounting of a ceiling or wall covering on the structural rails. To this end, first panels of a first row of panels are fixed to the structural rails by a first longitudinal side arranged in the area of the space-delimiting surface contiguous to the panel surface. This is done by mounting clips or by holding clips, for example hidden, which can be mounted on the underside. For further mounting, a mounting clip is disposed on the structural rail by rotating movement about an axis of rotation located perpendicular to the panel surface, so that the mounting clip is movably mounted on the structural rail with, for example, two tabs. The mounting clip is then pushed along the structural rail with a housing toward the second side of the first panel opposite the space-limiting side, so that the first panel, movably mounted, rests in the housing in the direction of the longitudinal axis of the panel.

The second panel of a second row of panels is then arranged by and locked with the longitudinal locking profiles in the longitudinal locking profile of the first panel. To fix the second On the side of the second panel opposite the first row of panels, a mounting clip is in turn mounted on the structural rail and is pushed with its housing towards the second side of the second panel.

Other rows of panels are mounted in correspondence with the mounting of the second row of panels, the last row of panels of a panel surface also being able to be fixed in the structural rail, for example, in correspondence with the first row of panels, in the side facing the space-delimiting surface with a mounting clip or, for example, with a concealed and underside mounted retaining clip.

The mounting of the panels on the mounting clips, which in turn are movably mounted on the structural rail, enables fully floating mounting and thus free movement of the panel surface between the space-delimiting surfaces.

By fully floating mounting is meant that the panel surface can be freely moved in its plane in four directions offset by 90 ° from each other to the respective adjoining space-delimiting surfaces.

Movement along the longitudinal axis of the panels, i.e. transverse to the longitudinal axis of the structural rails, can be accomplished by sliding the panel along the mounting clip housing, i.e. by varying its position relative to the mounting clip. Movement of the panel surface in the direction of the longitudinal axis of the structural rail is performed in conjunction with the mounting clip by sliding the mounting clip along the structural rail. Accordingly, during movement of the panel surface in the direction of the longitudinal axis there is no relative movement between the mounting clip and the panel.

Generic panels comprise materials derived from wood, in particular boards from materials derived from wood, which are used as wall or ceiling cladding. By wood-based materials is meant here in particular the classic wood-based materials, such as plywood or veneer boards, or particle-based wood-based materials, for example, fiberboard , chip boards or OSB boards. Generic panels can also comprise wood and plastic composites, i.e. materials made by extrusion or injection molding processes, that contain wood particles. The generic panels preferably comprise a covering. The coating may include, for example, real wood, laminate (DPL: direct pressure laminate, CPL: continues pressure laminate, HPL: high pressure laminate, applied varnish, for example, by direct pressure or indirect pressure, a plastic or plexiglass plate or sheet, a metal plate, a WPC plate or sheet, or combinations thereof.

This means that the generic panels can be configured in any case with several layers. In this sense, the panel itself can have a multilayer configuration, for example, a board made of wood-derived material and a covering. It is also possible to configure the wood-based material board itself and the coating itself, respectively, with several layers.

The panels in the sense of the invention are characterized in that they are configured in the form of a plate and have, on their longitudinal sides and on their transverse sides, locking profiles in correspondence with each other for bonding without adhesive or joints, at least presenting the longitudinal sides and the transverse sides corresponding locking profiles with each other. Alternatively, a transverse side and a longitudinal side can also have identical profiles in each case, so that a first panel can be joined on a transverse side to a longitudinal side of a second profile. A panel surface is to be understood as meaning a plurality of panels which are connected to one another with the help of their corresponding connection means and which form, for example, a seamless surface, that is, a surface coating.

The corresponding locking profiles are configured in particular as rotating profiles, pivoting profiles and / or rotating pivoting profiles. The locking profiles can also be configured as so-called snap button profiles. Alternatively or additionally, both longitudinal and transverse locking profiles may have a so-called 5G lock.

By the first panels of a first row of panels is meant panels that are joined together on their transverse sides (short side edge) by corresponding locking profiles and are part of a wall or ceiling covering. In this case, a first row of panels is a first or last row of panels on a panel surface. Therefore, the first row of panels can be a row of panels that closes the panel surface, that is, that adjoins, for example, on one of its longitudinal sides with a space-delimiting surface.

For wall or ceiling coverings made up of panels with corresponding locking profiles, it is necessary for the first row of panels to have at least two direct connection points to the substructure, specifically, on the one hand, in the area of the external side (for example , the side directed towards the space-delimiting surface) of the first panels, and a joint in the area of the blocking profile corresponding to a second panel. The connection directed towards the space-delimiting surface can also be carried out, for example, with the mounting clip, although in this case a retention clip can be used, which is concealed in the bottom side of the panel in the wall area and engages the structural rail.

Mounting clip is to be understood as a fixing means that creates a movable connection between the structural rails of the substructure and the panel surface. The mobile mounting of the mounting clip on the structural rails is done, for example, in such a way that the mounting clip has tabs to mesh around sections of the structural rail, whereby the mounting clip can be moved along the structural rails along the direction of the longitudinal axis of the structural rails.

In order to arrange the mounting clip on the panel, it is provided that the mounting clip meshes with a housing in a recess in the panel. The housing may in particular have a first arm which protrudes from a surface of the mounting clip and comprises the housing.

For mounting the panels in the housing it is preferably provided that a section of the first arm meshes around a section of a groove flank, for example a lower groove flank, of the locking profile. In this case, the groove flank rests with a section on or in the housing and can be moved along the housing.

Fully floating mounting is carried out in such a way that the panel surface can be moved in its entirety in the direction of the longitudinal axis of the structural rails together with the mounting clips, while the panel surface moves transversely to the direction of the longitudinal axis of the structural rails, in which the sections of the panel that rest on the housing of the mounting clips move.

The structural rails in particular have a hat-like cross section, that is, they have a U-shaped base body, in which the free ends of the arms can be folded out at an angle, for example 90 ° , and configure ribs facing in the opposite direction. The structural rails are preferably mounted with their base body directly on the wall or ceiling or other supporting structure, so that the ribs are oriented remotely and broadly parallel to the wall or ceiling.

In wall and ceiling coverings consisting of panels with corresponding locking profiles, there is a danger of a domino effect if a panel is separated from the substructure. In this case, a first panel, for example, separates from the substructure and slides out of the corresponding locking profile of the second panel. As a result of the separation of the corresponding locking joint, the second panels are no longer attached to the substructure on the one hand and consequently these also separate from the mounting clip and the corresponding locking joint and fall off.

It can then happen, for example, that a separated panel accidentally causes in the marginal area of a panel surface the fall of large parts of the panel surface or of the entire panel surface (domino effect).

A safety element against fall is understood as a means or a device that, in addition to the locking profiles and the housing in the mounting clip, allows additional fixing of the panels that clearly hinders or prevents the separation of a first and / or a second panel and in particular a domino effect.

By the simultaneous arrangement of the fall protection element, it is understood here that the fall protection element is arranged during the longitudinal connection of the first and second panels, that is, when the two panels are locked by means of locking profiles. That is, the process of blocking and disposing of the safety element against falling is carried out at least partially at the same time. By a subsequent arrangement of the fall protection element it is understood that the installation / assembly of the fall protection element is carried out at the end of the blocking of the blocking profiles. Therefore, before joining it means that the fall protection element is mounted before joining the locking profiles.

According to a variant of the invention, the safety element against falling is arranged in the area of the blocking profile. The safety element against fall can then be configured as an adhesive means that is arranged, for example, in the area of the corresponding locking profile and sticks it. Glues can be used in particular as adhesives. In a particularly preferred way, the fall protection element is configured, for example, as a mechanical component that acts on the existing locking profile or on the underside of the panel. The fall safety element can be configured in particular as an interlocking body which engages in an interlocking body housing arranged on a panel.

Particularly preferably, on the first and / or on the second panel, there is located at least one locking body housing for the configuration of a safety element against falling, in which a locking body engages preferably arranged in the clip of mounting. The engagement is carried out in particular before or during the locking of the corresponding locking profiles of the first and second panels.

The locking body housing can be configured in particular as a notch. The notch is particularly preferably configured as a slot extending in the direction of the longitudinal axis of the panel. The locking body housing is also configured in particular as an additional slot to the locking profile.

The inner body housing is preferably arranged in the area of the locking profile of the second panel. The suitable locking body is preferably arranged on the mounting clip. According to a preferred embodiment, such a housing can be provided as a second arm that is inserted into the locking body housing during the locking process of the locking profiles, whereby a particularly stable hold of the second panel is achieved.

According to a variant of the invention, the locking body is alternately arranged on the first arm that includes the housing. In these embodiments, the locking profile of the second panel is coupled to the locking profile of the first panel, and the locking body is inserted into the locking body housing at the same time, for example, during the pivoting movement to be performed.

As an alternative or in addition to the locking body and the locking body housing in the area of the locking profiles, the locking body housing is located on the underside of the first and / or second panel. This can also be made as a single notch or, for example, as a slot extending in the longitudinal direction of the panel. The corresponding locking body in each case can preferably be configured as a rib protruding from the base body of the mounting clip.

As the interlocking body housing is configured in the area of the underside of the first panel, the mounting clip is pushed toward a lower groove flank of the first panel, for example with a first arm comprising the housing, and a first Rib provided on the base body of the mounting clip is inserted into the locking body housing of the first panel. Alternatively or additionally, a second rib is inserted into a lower latch body housing on the second panel by pivoting the locking profiles inward.

Another embodiment provides for a tab element to penetrate both locking profiles when the second panel is mounted on the first panel, so that unlocking is prevented. To this end, the tab element is mounted on the blocking profile of the first or second panel. The tab element preferably engages a tab element housing, for example a slot, so that in the locked state it engages the two locking profiles of the first and second panels.

In addition or as an alternative to the current embodiments of the fall protection element, a closing strip with a base body and a retention strip is provided as a fall safety element, the base body being fixed to a roof covered by the panel surface or a wall or an adjoining space delimiting surface and the retaining strip being attached to the base body, in particular being detachably engaged in the base body, and abutting against the panels.

The configuration of the fall protection element as a retention strip is particularly simple and does not require any modification to the hitherto known locking profiles and mounting clips. The retention strip is attached to the base body in such a way that the retention strip rests in the marginal area of the panel surface on said surface and reliably prevents a separation of the panel in a direction perpendicular to the panel surface.

The base body is configured in particular in the form of a plate and is fixed with a mounting side on the ceiling, wall or space-delimiting surface. In order to configure the mounting of the retaining strip in a particularly simple way, the base body has an interlocking body housing, in which the retaining strip having an interlocking body is interlocked. In this sense, the interlocking body housing and the interlocking body are oriented in particular in such a way that the interlocking process is carried out in a direction perpendicular to the visible facing surface.

Alternatively or additionally, a non-adhesive bonding means can be placed on the lower groove flank of the first panels and fixed on the mounting clip. In this context, a connection means is understood to mean mechanical connection means, such as screws, bolts or the like, and not adhesive means. For connection, the connecting means is screwed, for example, into a lower groove flank of the first panel or inserted into a prepared notch and fixed, for example, screwed, in the mounting clip. In order to enable the panel, despite the joining means, a sufficient movement transverse to the direction of the longitudinal axis of the structural rails, the joining means is also movably mounted preferably also transverse to the direction of the longitudinal axis of the structural rail for example, through an elongated hole.

The object of the invention is also achieved by a wall or ceiling cladding having a substructure, which can be mounted on a wall or ceiling, with structural rails and a panel surface, floatingly mounted on the structural rails by clips mounting, with a plurality of panels joined to each other on the longitudinal sides and / or the transverse sides by means of locking profiles corresponding to each other and possible to join without adhesive, at least the mounting clips being mounted on the structural rails in a mobile way in the direction of the longitudinal axis of the structural rails and the panels being mounted on the mounting clips so as to be movable transverse to the direction of the longitudinal axis and with a safety device against falling that at least by sections prevents accidental separation of the structural rail panels.

The ceiling and wall cladding according to the invention can be mounted particularly easily and quickly without tools on the structural rails. The movable mounting of the mounting clips and the movable mounting of the panels in the mounting clip housings ensure that the panel surface can move as expansion and contraction movements occur between the space delimiting surfaces, without generating stresses on the panel surface. Since free movement of the panel surface can also be performed in the area of the space-delimiting surface due to the special mounting of the mounting clips and of the panels in the mounting clips, the ceiling and wall cladding is suitable also to compensate for large expansion and contraction movements that can be generated, for example, in the area of wet spaces. Locking profiles ensure that the panel surface remains as one unit and remains seamless. In case of strong movements of the panel surface that can be generated, for example, due to expansion and contraction movements of the materials derived from wood, the fall protection element also prevents domino effects that may occur. they cause the accidental fall of several rows of panels or of the entire surface coating of the substructure.

According to a variant of the invention, the panel surface comprises at least a first row of panels fixed by means of mounting clips on the structural rails and a second row of panels, the second panels being joined by a first longitudinal side to the first panels of the first row of panels by means of the corresponding locking profiles and are mounted on a second longitudinal side, opposite to the first longitudinal side, on the structural rails by means of the mounting clips, being arranged in the area of the locking profiles joined to each other by the panels of the first and second row of panels a fall safety element that prevents accidental separation of the panels from the structural rail.

In a particularly preferred way, the mounting clip has at least one interlocking body which is interlocked in an interlocking body notch on the rear side of a panel of the first row of panels and / or in an interlocking body notch in one panel from the second row of panels. The locking body can here be configured as a rib, in particular elastic, protruding from the surface of a base body of the mounting clip. The rib and, if appropriate, also the locking body notch can be arranged, for example, at an angle <90 ° to the surface of the base body of the mounting clip for a particularly secure fastening of the panels.

To support the housing in the notch of the locking profile, the mounting clip preferably has a first arm that protrudes from the surface of the base body of the mounting clip and comprises the housing. The first arm may, for example, have a retaining section which protrudes perpendicularly from the surface of the base body and comprises a housing located after the retaining section, oriented, for example, at an angle of 90 ° / - 15 ° with respect to the retention section and configured to mesh in the notch of the locking profile, for example, to rest on a lower groove flank.

According to a variant of the invention, the locking body housing is arranged in the area of the locking profile of the second panel and the locking body has a second arm that protrudes from the base body of the mounting clip and is locked in the housing interlocking body. The second arm may also protrude perpendicularly, eg, with a first section, from the surface of the base body of the mounting clip and may be interlocked with a second section in the latch body housing. The retaining section and the first section can then be arranged widely in parallel, while the second section and the housing can be oriented at their free ends in opposite directions.

Alternatively, the interlocking body is preferably arranged on the first arm and interlocked in the interlocking body housing on the locking profile of the second panel. In this case, the locking body section penetrates relative to the housing, for example, in a widely opposite direction. According to a variant of the invention, the fall protection element has a magnet that fixes a panel of the first and / or the second row of panels on the mounting clip and / or the structural rail. The magnet can be arranged on one of the panels and can interact with a mounting clip configured in a ferromagnetic way or a structural rail configured in an electromagnetic way or the magnet is arranged in the mounting clip and interacts with a ferromagnetic material integrated in the panel . As an alternative to the magnet, magnetized wood particles can also be arranged in the area of the locking profiles or on the underside of the panel, creating a magnetic connection with the mounting clip. Instead of a ferromagnetic material, a second reverse polarity magnet can also be arranged to increase the magnetic force. The magnetic joint also ensures a completely floating mounting of the panel surface on the structural rails.

In addition or as an alternative to the embodiments of the fall protection element mentioned above, according to a variant of the invention, the fall protection element may comprise a closure strip with a base body and a retention strip, being fixed the base body on a space-delimiting surface (ceiling or wall) and the retaining strip being attached to the base body, in particular detachably interlocked in the base body, and supported against the panels.

The fall protection element may also comprise an adhesive means that joins the profiles together. corresponding locking devices, so that they cannot be separated from each other without breaking. The adhesive means can be arranged directly in the area of the locking profiles. In this sense, the provision of adhesive in the area of the locking profiles ensures that they are also floatingly mounted.

As a safety element against falling, a connecting means can also be fixed on the first panel, in particular on a groove flank, for example, a lower groove flank of the first panel, and fixed on the mounting clip. By means of connection is meant in this context a mechanical coupling component (eg screws, bolts, hooks or the like). The connecting means is configured in particular separately from the panels and the mounting clip. Adhesive means are not to be understood in this context as bonding means. The attachment means passes through or is mounted on the lower groove flank and is firmly attached to the mounting clip in a direction perpendicular to the panel surface. In order to also ensure floating mounting, the connecting means is movably mounted at least on the mounting clip in the direction of the longitudinal axis of the panel, for example, by an elongated hole.

Another configuration of the fall protection element, which may be configured as an alternative or in addition to the aforementioned embodiments, comprises a tongue element that engages the longitudinal locking profiles joined to each other. The tab element can be arranged, for example, in a slot, for example, additional, located in the locking profile, such that when locking the locking profiles engages in a slot, for example, additional, located in the second lock profile, and lock the corresponding lock profiles to each other. Locks of this type are known, for example, as 5G locks in the floor panel sector.

The object of the invention is also achieved by means of a mounting system for the manufacture of a floatingly installed wall or ceiling cladding and formed by panels with correspondingly corresponding locking profiles, comprising at least one substructure possible to be mounted on a wall or ceiling with structural rails and a mounting clip movably mounted on the structural rails in the direction of the longitudinal axis of the structural rails with a housing for engaging a notch in a first panel, the mounting clip presenting two configured tabs to engage behind the structural rail and located on opposite sides of a longitudinal axis and a transverse axis of the mounting clip, so that the mounting clip can be movably mounted on the structural rail by rotating movement about an axis turning located perpendicular to the longitudinal axis and the transverse axis.

The mounting system in a particularly advantageous manner enables tool-free mounting of wall or ceiling panels that are joined together by corresponding locking profiles. This further ensures a completely floating mounting of the panel surface, so that the created panel surface can execute, for example, expansion and contraction movements generated within the space-delimiting surfaces.

The structural rails have, as already mentioned, for example, a hat-type cross section with a u-shaped base body and folded areas that are arranged at the free ends and configure the ribs for the flanges of the mounting clips. The ribs are preferably oriented at an angle of 90 ° to the arms of the u-shaped base body and therefore broadly parallel to the bottom of the U. The free ends of the ribs are preferably oriented in opposite directions.

Flanges are understood to be connecting elements to engage at least in sections around the ribs and to slide along the ribs. The mounting clip preferably has a base body, for example in the form of a plate. The flanges are preferably configured in a single piece with the base body and are formed, for example, by punching therefrom. The flanges can have a first flange section protruding from the surface of the base body and a second flange section that follows the first flange section. The second flange section can be widely arranged parallel to the surface of the base body and configured as a tongue element. This prevents slipping of the mounting clips and ensures simple movement of the mounting clips along the ribs.

The special arrangement of the flanges around the longitudinal axis is carried out in such a way that the free ends of the second flange section are oriented in each case in the direction of the longitudinal axis. By additional arrangement around the transverse axis it is also achieved that the mounting clip can be pushed at the same time with the tabs towards both ribs by a rotary movement about a rotation axis located perpendicular on the surface of the base body of the clip mounting. The flanges are preferably arranged with specular symmetry around the transverse axis and the longitudinal axis.

In order to enable a non-visible mounting on the longitudinal side of the first panel, a retaining clip has been provided which can be fixed to the panel and movably mounted on the structural rail in the direction of the longitudinal axis of the structural rail. The retention clip can be attached to the rear side of the panel. To ensure a floating installation of the panel surface, it can be movably fixed across the structural rail on the rear side of the panel. This can be done, for example, with the help of an elongated hole in the clip. retention, whereby the retention clip is fixed, for example, screwed into the panel.

According to the invention, the mounting clip has a first arm which extends from the surface of the mounting clip and comprises a first retaining section and the housing, which is located downstream of the retaining section and is oriented essentially transverse to the retaining section and widely parallel to the surface of the mounting clip, for gear in the notch. That is, the angle between the retaining section and the housing is preferably 90 ° / - 2 °.

To make accidental separation of individual panels more difficult and to prevent in particular a domino effect when the panels fall, the mounting clip has, in addition to the housing, a safety element against falling. To this end, an interlocking body is arranged additionally to the housing in one of the panels for the gear in an interlocking body housing. The locking body housing can be arranged depending on the positioning of the locking body in the mounting clip on the underside of a panel or in the area of the corresponding longitudinal locking profiles.

For engagement of the locking body in a locking body housing arranged in the area of the locking profiles, a locking body section is provided which extends from the retaining section of the first arm. The latching body section extends in a direction widely opposite to the housing. Alternatively, a second arm is provided which extends from the surface of the base body of the mounting clip and comprises an interlocking body for interlocking in the interlocking body housing.

Additionally or alternatively, the latch body may also be configured to engage a latch body housing disposed on the underside of a panel. To this end, the mounting clip has in a section, arranged in the assembled condition of the mounting clip on the lower panel and not in the area of the locking profiles, a rib that extends from the surface of the body of mounting clip base. The rib is clearly shorter compared to the first or second arm and engages exclusively in an interlocking body housing arranged on the underside in at least one of the panels. The interlocking body housing can be made, for example, as a slot on the underside.

The rib is configured as a fold of an outer edge of the mounting clip, although it can also be punched out from the base body of the mounting clip. An angle between the rib and the surface of the mounting clip is preferably <90 °, the free end of the rib being inclined towards the center axis of the mounting clip. This enables a particularly secure clamping of the rib in the interlocking body housing

Although some aspects have been described in relation to a device, in particular a wall or ceiling covering or a mounting system, it is evident that these aspects also represent a description of the corresponding installation procedure, so that a block element or a The constructive element of a device is also to be understood as a corresponding process step or as a characteristic of a process step. Similarly, the aspects described in connection with a process step or as a process step also represent a description of a block or a corresponding detail or feature of a corresponding device, in particular the wall or ceiling cladding or the system mounting.

Figure 1 schematically shows in cross section a section of a roof lining 1. The roof lining 1 comprises a plurality of panels joined together by their corresponding joining profiles 2. In Figure 1 two panels are shown, a first panel 1a and a second panel 1b, which are joined together by their corresponding locking profiles 2 arranged on the longitudinal side.

In the area of the locking profiles 2, a mounting clip 3 is arranged, which acts with a housing 4a in a lower groove flank 5 of the corresponding locking profile 2 of the first panel 1a. The lower groove flank 5 rests on the housing 4a. The corresponding locking profile 2 is configured as a sG connection, in which a tongue element 6 is interlocked in a groove 7 in the lower groove flank 5 and in a groove 8 in the second panel 1b.

The mounting clip 3 has a flat base body 9. From the surface 3a, directed towards the panels 1a, 1b, from the base body 9 there protrudes in the direction of the first and from the second panel 1a, 1b a first arm 4 which extends perpendicular to the surface. The first arm 4 comprises a retention section 10 and a housing section with housing 4a. Retaining section 10 is oriented largely parallel to surface 3a of mounting clip 3.

Mounting clip 3 is movably mounted by two tabs 32 on a structural rail 12 of a substructure. The structural rail 12 is fixedly attached to a ceiling 13 by means of a screw connection 14.

The mounting clip 3 is movably mounted by the flanges 32 in the direction of the longitudinal axis (L) of the structural rail 12. The lower groove flank 5 is in turn movably mounted on the housing 4a, so that the ceiling lining 1, made from panels 1a, 1b, moves along its plane in four directions. The roof lining 1 is then completely floatingly mounted.

The fall protection element 15 is configured by means of the groove 7 in the flank of the lower groove 5, the groove 8a in the tongue 8 and the tongue element 6 that meshes in both grooves 7, 8a. By separating the side (not shown here) of the first panel 1a opposite the lower groove flank 5, the tongue element 6 prevents the lower groove flank 5 from sliding out of the corresponding locking profile 2, so that also the first panel 1a is attached to the ceiling 13. This also reliably prevents a domino effect. On the opposite side, the tongue element 6 also prevents an exit of the tongue element 6 from the corresponding locking profile 2 in the event that the side of the second panel 1b opposite the tongue 8 separates, whereby a fall of the second panel 1b or a domino effect.

Figure 2 schematically shows a cross section through a ceiling lining 1 in the panel area with corresponding locking profiles 2 arranged on the longitudinal side. The arrangement of the roof lining 1, the structural rail 12 and the first and the second panel 1a, 1b with the corresponding locking profiles 2 is identical to the representation in figure 1. The mounting of the mounting clip 3 is also identical in structural rail 12.

To protect the panels 1a, 1b against falling, in particular to prevent a domino effect, a second arm 28 is arranged on the mounting clip 3, protruding from the surface 3a of the base body 9 of the mounting clip 3. The second Arm 28 has an interlocking body 16 that extends into an interlocking body housing 17 configured as a slot. The interlocking body housing 17 is disposed on a second panel 1b of the second row of panels.

The embodiment of the fall protection element 15, shown in FIG. 2, prevents in particular a domino effect, because in case of separating the first panel 1a, it can fall from the ceiling 13, but the second panel 1b remains safely suspended from the ceiling 13 by the interlocking body 16 and the interlocking body housing 17.

Figure 3 shows another embodiment of the fall protection element 15. The constructive design of the roof 13, of the structural rail 12 and of the fixing of the mounting clip 3 on the structural rail 12, as well as of the corresponding locking profile 2 it is identical to the constructive design of figures 1 and 2.

However, in the embodiment depicted here, the latch body 16 is not disposed on a separate second arm 28 on the mounting clip 3, but extends from the retaining section 10 of the first arm 4. In This embodiment also prevents in particular a domino effect in case the first panel 1a is detached, because the second panel 1b is held by the locking body 17.

Figure 4 schematically shows a cross section through a roof cladding 1. The structural design, consisting of the roof 13, the structural rail 12, the mounting clip 3 and the roof cladding 1, is identical to the design described in Figures 1 to 3.

Drop safety member 15 is configured here as rib 18 extending from base body 9 of mounting clip 3 and engages in an interlocking body housing 17 configured as slot 19 and disposed on underside 1c of first panel 1a. By separating the side of the first panel 1a opposite the lower groove flank 5, the rib 18 engaged in the groove 19 prevents the first panel 1a from sliding out of the corresponding locking profile 2 and, therefore, a fall of the first panel or from another panel.

Figure 5 shows another embodiment of the ceiling lining 1. The structural design, consisting of the ceiling 13, the structural rail 12, the mounting clip 3, the ceiling lining 1 and the locking profile 2, is identical to the design described in Figures 1 to 4. Figure 5 also shows the fall protection element 15 represented in Figure 4. As additional security, the mounting clip 3 has a second rib 18a that engages a second slot 19a arranged in the second panel 1b and configured on the underside as an interlocking body housing 17. Naturally, the fall protection element 15 can also be configured by means of a second rib 18a with a second groove 19a, that is, without the first rib 18 or the first rib slot 19.

Figure 6 shows another embodiment of the fall protection element 15 that safely prevents the first panel 1a from falling. In this embodiment, the lower groove flank 5 of the first panel 1a is screwed into the mounting clip 3 with a connecting means, in this case a screw 21. In order to allow a movement of expansion and contraction of the panels in transverse to the direction of the longitudinal axis (L) of structural rail 12, the screw is located in an elongated hole (not shown here) which extends in mounting clip 3 transverse to the direction of the longitudinal axis of structural rail 12. This it reliably prevents the fall of the first panel 1a and therefore also of the second panel 1b, while the panels 1a, 1b can continue to move freely in the plane of the panel both in the direction of the longitudinal axis (L) and in the transverse direction of the direction of the longitudinal axis (L) of the structural rail 12.

Figure 7 shows a structural rail 12 configured as a bent sheet. The structural rail 12 has a U-shaped base body 33 in the cross section. The free ends of the U-shaped profile arms 20 are angled at a 90 ° angle to the profile arm 20 and form ribs 34. The two ribs 34 are configured to accommodate the mounting clip 3.

The mounting clip is shown in FIG. 8. The mounting clip 3 presents the flat base body 9, from whose upper side 3b two first arms 4 with a retaining section 10 and a housing 4a extend. The retaining section 10 extends widely perpendicular to the surface 3a of the flat base body 9. The first arms 4 are then broadly L-shaped. Two holes 9a have also been shown, through which can be seen the flanges 32 extending from the bottom side 3c of the flat base body 9. The flanges 32 are also configured in the L-shaped cross section. Figure 9 shows a retaining clip 11 which can be used, for example , for mounting a first row of panels 1a. The retaining clip 11 is fixed, in particular screwed, on the side of the panels 1a arranged in the wall / ceiling mounted state. To this end, the retaining clip 11 has an elongated hole 22 arranged centrally here in the retaining clip 11. The retaining clip 11 also has, at its transverse edges 11 respectively, a gear arm 23 to engage around the structural rail and has on its longitudinal sides two ribs 24 to engage the profile of the structural rail 12.

Figures 10a and 10b show another embodiment of a fall protection element 15 configured as a closure strip 24. The closure strip 24 has a base body 25 and a retention strip 26. The closure strip 24, shown here, it is configured for wall mounting and for securing a ceiling lining 1 or a wall covering. The base body 25 is fixed with a mounting side 30 on a wall, for example, by means of a screw or adhesive connection. The base body 25 has an interlocking body housing 29. In order to fix the retaining strip 26 in the base body 25, an interlocking body, in this case an interlocking strip 27, is configured in the retaining strip 26, configured to interlock in the interlocking body housing 29 in the base body 25.

After, for example, the ceiling lining 1 is manufactured, the base body 25 is fixed on the adjoining wall (not shown here). The retaining strip 26 is then inserted with its interlocking strip 27 into the interlocking body housing 29. The base body 25 is arranged on the wall such that the retaining strip 26 with its upper side 26a rests in the ceiling lining 1. This particularly reliably prevents the first panels 1a from falling, ie the ceiling panels arranged on the wall side or the wall panels arranged on the ceiling side.
