[0001] Wall system with two wall elements connected to each other by at least one connector
[0002] Description
[0003] The proposed solution concerns in particular a perforated wall system for a vehicle.
[0004] Perforated wall systems for vehicles are known, for example, from WO 2018 / 185149 A1. These comprise at least one flat perforated wall element for fastening to a component of the vehicle that is fixed to the body, for example to a pillar of the vehicle body within a vehicle-side loading space. The perforated wall element has a plurality of fastening holes, which are arranged, for example, regularly and in particular in several rows, and to which modular components can be fastened. A particularly effective fastening of modular components, e.g. for furniture modules, in order to be able to flexibly configure the interior of the vehicle via the perforated wall system, is possible, for example, using a fastening element disclosed in WO 2018 / 185149 A1. This fastening element enables tool-free fastening of modular components to a perforated wall defined by at least one perforated wall element.
[0005] In previously known perforated wall systems for vehicles, it is common to design a continuous surface, for example, to create an interior wall in a vehicle's interior, as a perforated wall consisting of one or more perforated wall elements. While this allows for extremely flexible fixing and positioning of modular components within the vehicle, lining a vehicle's interior exclusively with perforated wall elements can be comparatively costly. Furthermore, the design options are comparatively limited if a surface without mounting holes is desired in at least some sections of the perforated wall.
[0006] In this respect, the proposed solution provides a remedy.
[0007] In particular, a perforated wall system for a vehicle is proposed, comprising at least one flat perforated wall element extending substantially along a longitudinal direction and a width direction perpendicular thereto. The perforated wall system further comprises at least one filler plate, which is connected to the perforated wall element via at least one connector of the perforated wall system at a longitudinal edge of the perforated wall element extending along the longitudinal direction and is fixed in its position relative to the perforated wall element.
[0008] A proposed perforated wall system is therefore based on the basic idea of combining a perforated wall element with at least one filler panel and mechanically securing such a filler panel to the longitudinal edge of the perforated wall element via at least one connector, so that areas in a vehicle interior can be covered quickly and easily even without a perforated wall element. The filler panel can, for example, be made of a different material than the perforated wall element and, when installed, have a felt, textile, and / or leather covering or be coated in another way to give the filler panel a desired, aesthetically pleasing external appearance from the customer's perspective.
[0009] When connected to the at least one perforated wall element, the at least one filler plate extends substantially along the longitudinal direction and the width direction. Via the at least one connector and the arrangement on the longitudinal edge of the perforated wall element, the filler plate thus extends substantially along the same plane and thus continues a wall defined by the perforated wall element (e.g., for an interior wall or ceiling surface in the interior of the vehicle).
[0010] In one embodiment, the perforated wall system comprises a combination of several perforated wall elements and at least one filler panel, which is intended and configured to form an interior wall and / or ceiling panel for the interior of the vehicle. A combination of several (at least two) perforated wall elements and at least one filler panel thus allows at least two areas for an interior wall and / or ceiling panel in the interior of the vehicle to be defined, to which modular components can be attached via the fastening holes in the perforated wall elements. In contrast, a third area of the interior wall and / or ceiling panel can be designed differently and cost-effectively using the at least one filler panel.
[0011] In this context in particular, it can be provided that a filler panel is arranged between two perforated wall elements and is connected to each perforated wall element at one (e.g. upper and lower) longitudinal edge via at least one connector. For example, the perforated wall element can be strip-shaped. In other words, the perforated wall element then extends with a length in the longitudinal direction that is a multiple of the width of the perforated wall element in the width direction, or conversely, the perforated wall element extends with a width in the width direction that is a multiple of the length of the extension in the longitudinal direction. Strip-shaped perforated wall elements for interior fittings on vehicles are not known in this form to date, especially not in combination with one or more filler panels in order to achieve a flexible design of the interior.
[0012] The at least one connector for connecting a perforated wall element to a filler panel can, for example, comprise a connecting section having a J-shaped or U-shaped cross-section. The connector can be inserted into and locked in place by means of the correspondingly shaped connecting section on an edge section forming the longitudinal edge of the perforated wall element or a longitudinal edge of the filler panel. A section of the perforated wall element or filler panel that at least partially forms the longitudinal edge is received between two opposing limbs via the J-shaped or U-shaped cross-section. This enables easier mounting of the connector to the perforated wall element or filler panel, and thus simple assembly of the perforated wall system. In particular, a (first) connection of the connector to the perforated wall element or filler panel can be made without tools via a correspondingly shaped connecting section.
[0013] Alternatively or additionally, the at least one connector can comprise a connecting section having an L-shaped cross-section and to which an edge section of the perforated wall element that at least partially forms the longitudinal edge or an edge section of the filler plate that at least partially forms a longitudinal edge of the filler plate is held. The perforated wall element or the filler plate can be easily attached to a connecting section with an L-shaped cross-section during assembly of the perforated wall system, or conversely, the connector can be attached to the edge section of the perforated wall element or the filler plate before further fixing.
[0014] The two aforementioned connecting sections with different cross-sections can also be provided in combination with one another on a connector part of the connector, wherein one connecting section is then provided for the connection to the perforated wall element or to the filler plate, while the other connecting section is provided for the connection to the respective other component, ie the filler plate or the perforated wall element.
[0015] For example, in one embodiment, a first connecting section with a J-shaped or U-shaped cross-section is provided on a connecting part of the connector for connecting to the perforated wall element and a second connecting section with an L-shaped cross-section is provided for holding the filling plate.
[0016] In an alternative embodiment, a first connecting section with a J-shaped or U-shaped cross-section for connecting to the filler plate and a second connecting section with an L-shaped cross-section for holding the perforated wall element can be provided on a connecting part of the connector.
[0017] The design of the connector part or the use of the different first and second connecting sections provided thereon can, for example, determine the assembly sequence during assembly of the perforated wall system. For example, the connector can be attached to one of the components without tools via a J-shaped or U-shaped connecting section, even if the other component is already secured to the other connecting section. Likewise, it is possible, for example, to attach the at least one connector to the perforated wall element after the perforated wall element has already been fixed to the vehicle, and then subsequently attach the filler panel to the fixed perforated wall element via the connector.
[0018] In one embodiment, the connector is designed in at least two parts, with at least a first and a second connector part. Designing the connector in at least two parts allows for further flexibility during assembly.
[0019] For example, in this context, it can be provided that a connecting section with an L-shaped cross section is formed on the first connector part and has a support leg that helps define the L-shaped cross section. The second connector part can also have an L-shaped cross section, in this case with a clamping leg. To secure an edge section (of the filler plate or the perforated wall element) to the connector, the edge section is positively received and locked between the support leg and the clamping leg. The first and second connector parts are thus detachable from one another and thus separated before a connection is established between the connector and the respective edge section.For example, an edge section can first be attached or placed on the L-shaped connecting section of the first connector part before the fixing to the edge section takes place via the second connector part to be connected to the first connector part and its clamping leg.
[0020] For example, the clamping leg of the second connector part protrudes from a base, which, together with the clamping leg, defines the L-shaped cross-section of the second connector part. To specify a defined assembly direction for the connection between the first and second connector parts, the base of the second connector part can be inserted into a guide channel on the first connector part. Consequently, a guide channel is formed on the first connector part, into which the base of the second connector part is inserted along an assembly direction for connecting the second connector part and the first connector part and for locking an edge portion between the support leg and the clamping leg.
[0021] At a front end of the base relative to the mounting direction, a lug can be formed on the base that projects transversely to the mounting direction. The protruding lug is dimensioned such that it is received in the guide channel with a form-fitting fit and, when the first and second connector parts are fixed to one another, rests against an end of the guide channel lying in the mounting direction and against opposing inner walls of the guide channel. This can be used to assist the contact of the clamping leg with the filler plate in that a fixing force, which is applied via a fastening element attached to the second connector part, is only used to displace the clamping leg once the base has reached an end position in the guide channel predetermined by the lug.
[0022] In one embodiment, the first connector part also has a base which, together with the support leg of the first connector part, defines the connecting section which is L-shaped in cross-section. In one embodiment, a locking area for at least partially receiving a fastening element that fixes the first and second connector parts to one another is formed on the first connector part between the guide channel and the base. In such a embodiment, it can be provided, for example, that the second connector part is first attached to the first connector part without tools during assembly of the perforated wall system and that the base of the second connector part is inserted into the guide channel of the first connector part for this purpose. The two connector parts are then fixed to one another using an additional fastening element, for example a screw or a bolt.For engagement of the corresponding fastening element, the first connector part has a locking area with a receptacle for the fastening element. For example, a threaded section of a screw can be screwed into the locking area as a fastening element to fix the two connector parts together and press the clamping leg of the second connector part against the support leg of the first connector part, thus clamping the edge section between the support leg and the clamping leg.
[0023] To assist in holding the fastening element to the locking area, the locking area can, for example, have toothed or threaded inner surfaces. This includes, in particular, the possibility of a clear distance between the toothed inner surfaces of the locking area corresponding to a core diameter of a (fastening) screw used as a fastening element. The toothings on the opposing inner surfaces can be offset from one another in an assembly direction of the fastening element, which corresponds, for example, to the longitudinal axis of the screw, and specifically by exactly half the amount of a thread pitch of the screw. Thus, when the screw is screwed in, its thread flanks can be effectively screwed in along the toothing of the locking area and in doing so assist in tightening the screw.
[0024] A design with toothed inner surfaces on the locking area is particularly advantageous when the first and second connector parts are each designed as longitudinally elongated profile elements and thus a connector defined thereby is designed as a profile assembly. Correspondingly elongated profile elements can therefore also extend over a large part of the length or over the entire length of a longitudinal edge of the perforated wall element and not just be provided in locally limited areas of the longitudinal edge. Connector parts extending over the entire longitudinal edge of the perforated wall element then also support an aesthetically pleasing appearance of the assembled perforated wall system in that a continuous connection is created between the perforated wall element and the filler panel via the corresponding connector, so that there is no visible gap between them.
[0025] In one embodiment, at least one recess, in particular a groove, for example a longitudinal groove extending in the longitudinal direction, is provided on a connecting section of the connector. Such a recess is provided for specifying a position of an additional fixing element for fixing the connecting section to the respective edge section. The at least one recess specifies a position in the width direction and along the longitudinal direction where the additional fixing element is to be attached. Such an additional fixing element can be, for example, a screw that is screwed from the outside into the respective connecting section and the edge section behind it.
[0026] To facilitate tool-free attachment of a J-shaped, U-shaped, or L-shaped connecting section to an edge section (of the filler panel or perforated wall element), one design variant provides for at least one leg of the (J-, U-, or L-shaped) connecting section to have an elastically mounted locking element that engages a recess in the edge section (of the filler panel or perforated wall element). In this way, the correspondingly designed connector can, for example, simply be inserted into the respective edge section and positively locked thereto.
[0027] In one design variant, a spacer can be arranged between a leg of a connecting section of the connector and an edge section (of the perforated wall element or the filler plate). Such a spacer serves, for example, with a narrower filler plate, to ensure sufficient locking at the connecting section. Thus, the spacer can compensate for the gap that would remain between two legs of a connecting section if the filler plate were too narrow. In such a case, the spacer still ensures sufficient clamping at the corresponding connecting section.
[0028] In principle, the filler panel can define an interior area for the vehicle without pre-drilled mounting holes. Alternatively or additionally, the filler panel can have a felt, textile, and / or leather covering on the inner side facing the vehicle's interior when the perforated wall system is installed, and / or be coated with a decorative surface.
[0029] In principle, in one embodiment, the filler panel can have one or more recesses, for example in the form of through-holes. Corresponding recesses in the filler panel are provided, for example, for at least one socket, a ventilation opening, an inspection opening, an opening for a control display, an opening for a light source, and / or an opening for a vehicle window.
[0030] The proposed solution further relates to a wall system for a vehicle, comprising at least two first and second flat wall elements. The first and second wall elements each extend (in a connected state) substantially along a longitudinal direction and a width direction perpendicular thereto. A first wall element is provided for fixing to a body-mounted component of the vehicle. The second wall element is connected to the first wall element via at least one two-part connector of the wall system at a longitudinal edge of the first wall element extending along the longitudinal direction, and its position relative to the first wall element is fixed.
[0031] A proposed wall system can, in particular, be designed as a perforated wall system according to the above explanations, in which one of the first and second wall elements is designed as a perforated wall element and the other wall element is designed as a filler panel. The two-part design of the connector connecting the two wall elements significantly simplifies the installation of wall elements in a vehicle in a proposed wall system—regardless of whether one of the wall elements is designed as a perforated wall element.
[0032] In particular, according to the above explanations, the connector can be designed in two parts with first and second connector parts, wherein the first and second connector parts are each designed as profile elements extending in the longitudinal direction. The connector is thus designed here as a profile assembly, via which two flat wall elements can be connected to each other at their longitudinal edges in a compact and easy-to-assemble manner.
[0033] In a proposed wall system, a connector part of the first and second connector parts can also have a connecting section with a J-shaped or U-shaped cross-section and / or a connecting section with an L-shaped cross-section. The advantages and features explained above for an analogously designed connector of a variant embodiment of a proposed perforated wall system can also apply to such a wall system. The proposed solution further relates to a vehicle with a variant embodiment of a proposed perforated wall system and / or a proposed wall system that is mounted in the interior of the vehicle, wherein the longitudinal direction along which the perforated wall element extends or the first and second wall elements extend runs parallel to a longitudinal axis of the vehicle pointing from the front of the vehicle to the rear of the vehicle.
[0034] Furthermore, the proposed solution provides an assembly method in which a variant of a proposed perforated wall system is mounted in the interior of a vehicle. In this case, a perforated wall element is first fixed to a component of the vehicle that is fixed to the body, for example to a body pillar, and optionally using a damping element that at least partially reduces the transmission of shocks and vibrations from the body to the perforated wall element. Subsequently, the at least one filler plate is secured to the perforated wall element via the at least one connector. Thus, the proposed solution allows a filler plate, designed according to customer requirements, to be easily mounted on a fixed perforated wall element during assembly.
[0035] For example, the at least one filler plate is plugged onto the perforated wall element via the at least one connector already attached to the filler plate. The filler plate is then pre-assembled, for example, with the at least one connector and is first plugged onto the perforated wall element already fixed in the interior without the need for tools and then secured using one or more fastening elements, such as fastening screws. This includes, for example, a variant in which a connector is attached to the filler plate which, on a free connecting section intended for connection to the perforated wall element, has a J-shaped or L-shaped cross-section with a leg having an elastically mounted locking element. This allows the connector already connected to the filler plate to be easily locked onto the perforated wall element already fixed to the vehicle during assembly.
[0036] An assembly variant is also conceivable in which the filler plate is mounted on the perforated wall element already fixed to the vehicle, without the connector being mounted on the filler plate. Instead, it can be provided, for example, that the connector or at least a connector part is already fastened to the perforated wall element and that the filler plate is placed and fixed thereto. The proposed solution also provides an assembly method for an embodiment variant of a proposed wall system. Here, the first wall element is first fixed to a body-mounted component of the vehicle, before the second wall element is attached to the first wall element via the at least one connector. In particular, the second wall element can also be plugged onto the first wall element via the at least one connector already attached to the second wall element.
[0037] The above explanations for an assembly method for a perforated wall system also apply to an assembly method for a variant of a proposed wall system.

[0053] Design variant in which an additional spacer is provided on an upper connecting section of the connector for clamping a narrower filler plate to the connector;
[0054] Figure 10 in a view corresponding to Figures 8 and 9, a further
[0055] Design variant in which a base of a second connector part of the connector, which is inserted into a guide channel, is extended compared to the design variants of Figures 6A to 9 and is formed at a front end with a (step) nose projecting in the transverse direction.
[0056] Figure 1A shows a partially sectioned side view of a vehicle F, in whose interior L a variant of a proposed (perforated) wall system is to be mounted. On a lateral, here left, side wall SW1 of the interior L, three strip-shaped first wall elements in the form of perforated wall elements 1.1 are mounted.
[0057] 1.2 and 1.3 are mounted firmly to the body. The strip-shaped perforated wall elements 1.1 , 1.2 and
[0058] 1 .3 each have at least one row of fastening holes for securing modular components in the interior L of the vehicle F. The perforated wall elements 1.1, 1.2, and 1.3 each extend along a longitudinal axis of the vehicle F and are spaced apart from one another along the vehicle's vertical axis. Accordingly, a first perforated wall element 1.1 is located in an upper area below a ceiling D of the interior L. A second perforated wall element 1 .2 extends approximately centrally, while a third perforated wall element 1 .3 is mounted close to the floor.
[0059] Corresponding to the rear view of Figure 1B, perforated wall elements 1.1', 1.2", 1.3" are also mounted in a mirror-image manner on an opposite, right-hand side wall SW2 of the interior L. In addition, the upper, first perforated wall elements 1.1, 1.1' are each adjoined by strip-shaped perforated wall elements 1.4 or 1.4", which are mounted on the ceiling D.
[0060] Consequently, in the vehicle F of Figures 1A and 1B, no perforated wall surface is provided between each two perforated wall elements 1.1 / 1.2 and 1.2 / 1.3 or 1.171.2" and 1.271.3". Instead, corresponding intermediate spaces are variably equipped with second wall elements in the form of (vario) filler panels 2A to 2D, as shown in Figure 2. These filler panels 2A to 2D are fixed to the longitudinal edges of the perforated wall elements 1.1 to 1.4 or 1.1" to 1.4'. The filler panels 2A to 2D enable a variable design of the interior L according to customer requirements and using a smaller number of perforated wall elements. Furthermore, it is not necessary to produce a continuous perforated wall paneling.
[0061] For example, in the embodiment variant of Figure 2, two filler plates 2A and 2B are provided between the first, upper strip-shaped perforated wall element 1.1 and the second, middle strip-shaped perforated wall element 1.2, which are arranged one after the other along the longitudinal axis and thus along a longitudinal extension direction y. These filler plates 2A, 2B each have recesses 20A and 20B, which are provided, for example, for window openings. Between the second, middle perforated wall element 1.2 and the third, lower perforated wall element 1.3, two filler plates 2D and 2C are also provided, which are arranged one after the other in the longitudinal direction y. Here, too, recesses 20C, 21C and 20D can be provided, for example for inspection hatches, switches, displays or sockets.
[0062] According to the rear view in Figure 3, a corresponding combination of perforated wall elements 1.1", 1.2" and 1.3" as well as filler panels 2A" and 2D" is also provided on the opposite side wall SW2 of the interior space L. A filler panel 2E is also provided on the ceiling D of the interior space L, here between the two strip-shaped perforated wall elements 1.4 and 1.4" on the ceiling side. The interior space L can be variably designed by cladding the interior space L with a combination of perforated wall elements and filler panels. For example, the filler panels 2A to 2E, 2A' and 2D' can be covered with different coverings on their inside. In contrast to the perforated wall elements 1.1 to 1.4 and 1.1 ' to 1.4', they can also be coated and / or made from a different material, in particular from a different wood than the perforated wall elements 1.1 to 1.4 and 1 .1 ' to 1.4', which are typically made from a wooden material.
[0063] In a correspondingly paneled interior space L, modular components, for example a furniture module M according to Figure 3, can be easily fixed to the fastening holes of the perforated wall elements 1.1 to 1.4 and 1.1' to 1.4', for example using fastening elements known from WO 2018 / 185149 A1.
[0064] In the embodiment shown, the perforated wall elements 1.1 to 1.4 and 1.1' to 1.4' are each fixed to components of the vehicle F that are fixed to the body, typically to members that are accessible from the inside and have already been perforated by the vehicle manufacturer. The sectional view in Figure 4 shows, as an example, the fixing of the perforated wall elements 1.1 and 1.2 via fixing elements P1 and P2 to members of the left side wall SW1. In order to at least partially decouple the perforated wall elements 1.1 and 1.2 fixed to the body from the body and to cushion vibrations and shocks, a damping element in the form of a rubber disc DF1 or DF2 is provided between the member of the side wall SW1 and the perforated wall elements 1.1, 1.2 on each fixing element P1, P2. The respective rubber disc DF1 or DF2 is located between the beam and an outer side of the perforated wall element 1.1 or 1.2, so that the perforated wall element 1.1 and 1.2 is elastically mounted on the respective pillar on the side wall SW1. This cushions any displacement of the vehicle cabin during travel. Furthermore, noise that would otherwise be generated by direct contact between a perforated wall element 1.1, 1.2 and the metal pillar of the body is avoided.
[0065] In the perforated wall system shown, the strip-shaped perforated wall elements 1.1 to 1.4 and 1.1' to 1.4' not only simplify assembly, as the strip-shaped perforated wall elements 1.1 to 1.4 and 1.1' to 1.4' are comparatively easy to handle. The perforated wall elements 1.1 to 1.4 and 1.1' to 1.4' are also more cost-effective to manufacture than perforated wall elements that would be used to fully cover a side wall SW1, SW2 or the ceiling D of the interior space L. In order to further facilitate the assembly of the filler panels 2A to 2E, 2A' and 2D' to the perforated wall elements 1 .1 to 1 .4 and 1 .1 ' to 1 .4', in particular to be able to easily replace filler panels if necessary, a profile assembly in the form of a two-part connector 3 is provided in the illustrated embodiment for fixing a filler panel to a perforated wall element.Figures 4 and 5 show, by way of example, the use of connectors 3 for securing the filler panels 2A and 2D to the first, upper strip-shaped perforated wall element 1.1 and the second, middle strip-shaped perforated wall element 1.2. A first connector 3 secures the filler panel 2A to an edge portion forming a lower longitudinal edge of the perforated wall element 1.1. A further, identically constructed connector 3 secures the filler panel 2A to the second, middle strip-shaped perforated wall element 1.2, here to an edge portion forming the upper longitudinal edge of the second perforated wall element 1.2. A further connector 3 secures the filler panel 2D to the edge portion of the second, middle perforated wall element 1.2 forming the lower longitudinal edge. Via a connector 3, a filling plate 2A to 2E, 2A', 2D' can be connected in the area of a longitudinal edge of a perforated wall element 1.1 to 1.4 and 1.1' to 1.4', so that each filler panel adjoins a perforated wall element lengthwise and extends essentially along a plane spanned by the longitudinal direction y and a width direction z or x running perpendicular thereto. The width direction z runs essentially parallel to the vehicle's vertical axis on the side walls SW1, SW2, while the width direction x for the ceiling-side perforated wall elements 1.4, 1.4' and the filler panel 2E attached thereto runs parallel to a vehicle's transverse axis.
[0066] According to the illustrations in Figures 6A and 6B, a connector 3 extending in the longitudinal direction y is constructed in two parts with a first connector part 31 and a second connector part 32. The connector parts 31, 32 are each designed as elongated profiles. The first connector part 31 has a first connecting section 311, which is U-shaped in cross-section, via which the first connector part 31 is fixed to an edge section forming the longitudinal edge of a perforated wall element. In addition, a second connecting section 312 is provided on the first connector part 31 for connection to a filler plate - in Figure 6A, the filler plate 2A is used as an example. The second connecting section 312 of the first connector part 31 is L-shaped in cross-section.The two connecting sections 311 and 312 protrude in mutually opposite transverse directions with respect to the longitudinal extension direction y of the first connector part 31, so that, for example, in Figure 6 the first connecting section 311 points downwards, while the second connecting section 312 points upwards.
[0067] At the first connecting section 31, the U-shaped cross section is defined by two opposing legs 311A and 311B. An outer leg 311A, i.e., the leg facing the side wall SW1 in the assembled state (and possibly somewhat longer), has an elastically displaceable locking strip 3110A at its end. Via this locking strip 3110A, the first connecting section 311 can snap into a recess designed as a locking groove R on a perforated wall element (see, for example, Figures 7A-7B, 8 and 9). A fastening groove 313B provided on the opposite, inner leg 311B of the first connecting section 311 - in this case V-shaped in cross-section - provides a position for a wood screw on the inner leg 311B, via which additional fixing of the first connecting section 311 to the respective perforated wall element can be achieved.A corresponding fastening groove 313A is also provided on the opposite outer leg 311A of the first connecting section 311, in order to provide additional fixation on this leg 311A if necessary. The fastening grooves 313A and 313B are offset in height from one another to prevent collision of wood screws being driven in from opposite sides.
[0068] At the second, upper connecting section 312, its L-shaped cross-section is defined by a base 312A and a support leg 312B extending perpendicularly thereto. The longitudinal edge of the filler plate, here the filler plate 2A, can rest on the base 312A. The edge section forming the longitudinal edge of the filler plate 2A is then additionally supported on the outer side by the support leg 312B of the second connecting section 312.
[0069] The second connector part 32, which is also L-shaped in cross-section, is provided for fixation to the second connecting section 312. The second connector part 32 has a base 320 and a clamping leg 321 extending substantially perpendicularly thereto. The base 320 can be inserted into a guide channel 3120 of the first connector part 21, which is formed between the two connecting sections 311 and 312 on the first connector part 31 and extends transversely to the longitudinal direction y.By inserting the base 320 of the second connector part 32 into the guide channel 3120 of the first connector part 31 along an assembly direction E running transversely to the longitudinal direction y, the clamping leg 321 of the second connector part 32 is arranged opposite the support leg 312B of the first connector part 31, in such a way that the edge section of the filler plate 2A resting on the base 312A of the second connecting section 312 of the first connector part 31 is clamped between the support leg 312B and the clamping leg 321. For better locking of the filler plate 2A between the two connector parts 31 and 32, a ribbed surface 3210 is provided on an inner side of the clamping leg 321 facing the support leg 312B.
[0070] To secure the second connector part 32 after it has been attached and pushed onto the first connector part 31 while clamping the filler plate 2A, a fastening element, here in the form of a screw 4, is provided. This screw 4 is screwed into a positioning groove of the clamping leg 321, which has a V-shaped cross-section. When the connector 3 is assembled as intended, the threaded portion of the screw 4 then engages in a toothed locking area 3124 of the first connector part 31. The locking area 3124 is formed below the base 312A of the second connecting section 312 and above the guide channel 3120. Opposing inner surfaces of this locking area 3124 are provided with transversely offset teeth. The offset of the teeth of one inner surface relative to the teeth of the opposite inner surface corresponds exactly to half the pitch of the screw 4.Thus, when screwing in the screw 4, its thread flanks can create an optimal thread along the toothing in order to fix the second connector part 32 to the first connector part 31 while clamping the filler plate 2A.
[0071] The fixation of the clamping leg 321 to the filler plate 2A can be further supported by an additional fastening groove 323 on the clamping leg 321. For example, a wood screw 5 can be screwed in as an additional fixing element, as shown in Figure 8. The fastening groove 323 for such an additional fixing element is located further outward on the clamping leg 321, so that the positioning groove 324 for the screw 4 is located between the fastening groove 323 and the base 320 on the second connector part 32.
[0072] For the assembly of the perforated wall system, it can be provided, for example, according to Figures 7A and 7B, that the connector 3 is first plugged or clipped onto an edge section of a perforated wall element 1.2 via its first connecting section 311. Figures 7A and 7B show such a plugging in with an assembled connector 3, i.e. with a connector 3 in which the second connector part 32 is mounted on the first connector part 31. To attach the filler plate, the connection between the connector parts 31, 32 is released via the screw 4, so that the clamping leg 321 can be spaced further apart from the supporting leg 312B or the second connector 32 can be completely separated from the first connector.
[0073] Alternatively, it is also possible to first mount the connector 3 onto a filler plate and then to attach the connector 3 with the filler plate to a perforated wall element 1.2 that is already fixed to the body of the vehicle F.
[0074] According to the illustration in Figure 9, the proposed perforated wall system via the connector 3 is also suitable for the use of narrower or thinner, i.e., less thick, filler panels 2A. For the clamping fixation to the second connecting section 312 via the second connector part 32, only one elongated spacer 6 is provided on the outside. Of course, several individual spacers 6 can also be used, which are spaced apart from one another along the longitudinal direction y. Thus, using one or more spacers 6, even filler panels of different thicknesses can be securely clamped to the connector 3.
[0075] In the further embodiment shown in Figure 10, the base 320 of the second connector part 32 is longer in the assembly direction E and is formed at a front end with a (stepped) nose 3201. The nose 3201 protrudes in a direction transverse to the assembly direction E at the front end of the base 320. With the nose 3201, the extended base 320 of the second connector part 32, when connected to the first connector part 31, rests in a form-fitting manner against an end of the guide channel 3120 lying in the assembly direction E (while the end of the base 320 remains spaced from the end of the guide channel 3210 in the embodiments explained above). When tightening the screw 4, the extended base 320 with the nose 3201 can prevent the base 320 from being displaced further into the guide channel 3210 of the first connector part 31, while the clamping leg 321 is not sufficiently pressed against the filler plate 2A.With the extended base 320 and the nose 3201, the serrated surface 3210 can thus be pressed more strongly against the surface of the respective filler plate 2A to 2E, 2A' or 2D' by tightening the screw 4. This is accompanied by an improvement in the fixing of the two connector parts 31, 32 to one another via the screw(s) 4 and a greater compensation of tolerances in the thickness of the filler plates 2A to 2E, 2A', 2D'. Figure 10 also illustrates that the locking region 3124 has a larger outer diameter d at its rear (relative to the assembly direction E) open end, i.e. the end facing the second connector part 32. a than further along. At the beginning of the toothed locking area 3124, the larger outer diameter d a which essentially corresponds to the outer diameter of the thread of screw 4. In the mounting direction E, this larger outer diameter d aa small inner diameter di. This inner diameter di corresponds to the core diameter of the thread of the screw 4. The larger outer diameter d a The screw 4 can engage more easily in the toothed locking area 3124 when screwed in. Furthermore, the screw 4 can also be provided with a blunt end without complicating assembly.
[0076] With the perforated wall system shown, combinations of perforated wall elements and filler panels can be mounted comparatively easily in an interior L of a vehicle F. In particular, the filler panels 2A to 2E, 2A' and 2D' can be easily replaced, for example, with another filler panel with a different function or a different design or with an additional perforated wall element.
