Definitions
- the present invention relates to a snap-in connection arrangement for connecting components, as well as a component, a structure and an assembly method.
- the area of application of the solution according to the invention includes all conceivable tasks in which at least two components are connected to one another, in particular surface elements such as floor elements, facade elements, roof elements, vehicle components, privacy screen elements and the like.
- This can also be a combination of a surface element with other commercially available components, such as profile elements, strip elements, frame elements, rod elements and the like.
- So-called tongue and groove connections for example, are known for producing connections between surface elements, as described in the document EP 021 464 3 A2 are shown.
- tongue and groove connections have the disadvantage that the connection can become detached very easily, for example during assembly and alignment, if a force acts on the components in the opposite direction to the joining direction.
- the document WO 00/20706 A1 discloses a connection profile in which two springs and two webs engage in depressions in the components to be connected.
- the document shows DE 299 24 454 U1 a solution in which floor panels are locked along their front edges in the vertical direction via one or more front projections of a panel by snapping into corresponding recesses of the other panel.
- the ones from the DE 38 06 091 A1 known solution relates to a composite of two or more profile strips structure, wherein a tongue and groove connection is made between two adjacent profile strips.
- One bar is provided with a longitudinal groove, and the other bar is provided with a longitudinal bar engaging in the groove.
- a latching connection arrangement is proposed as claimed.
- a component according to the invention and a structure according to the invention and an assembly method according to the invention are proposed and claimed. Any body that can be connected to at least one other body of the same or different structure is considered to be a component, with each body having at least one front and one rear and a plurality of front sides on which a strip can be arranged.
- the latching connection arrangement comprises a grooved strip (ie a first strip with a groove) with a first fastening region which preferably runs directly next to and parallel to the groove, ie along the groove.
- the groove serves to accommodate the tongue of a spring strip, which is explained further below.
- the fastening area is used for arranging the slot strip along a peripheral section of a component, so that the slot ideally runs along the edge of the component and is easily accessible next to the surface of the component.
- the component can be a cuboid component, preferably a surface element, such as a pane, a panel, a cladding, a slab, a slat and/or a strip, a roof, wall and floor element, a solar panel or the like.
- the slot strip extends in a first longitudinal direction, preferably transversely, preferably perpendicularly, to the slot strip cross section, and also in a first transverse direction.
- the longitudinal extension can approximately correspond to the transverse extension, and possibly also be smaller.
- the longitudinal extent or the transverse extent can also correspond to a circular diameter, in particular for the realization of point-to-point connections. This applies in particular when the groove strip contour viewed in the joining direction from the top view runs approximately circularly. Square, oval or other suitable contours are also conceivable, as long as the latchability with the spring strip described below is guaranteed as claimed.
- the snap-in connection arrangement additionally comprises a spring strip (ie a second strip with a spring) with a second fastening area, preferably running directly next to and parallel to the spring, ie along the spring.
- the tongue is intended to be inserted into the groove of the groove strip described above.
- the fastening area is used for arranging the spring strip along a peripheral section of a component, so that the spring ideally runs along the edge of the component and is easily accessible next to the surface of the component.
- the spring strip extends in a second longitudinal direction, preferably transversely, preferably perpendicularly, to the spring strip cross section, and also in a second transverse direction.
- the longitudinal extent of the spring strip can also be many times greater than the transverse extent, so that the typical strip character is created. In order to implement point-to-point connections, however, the length of the spring strip can also correspond approximately to the width of the spring strip cross-section or be less.
- the longitudinal extent or the transverse extent can also correspond to a circular diameter, in particular for the realization of point-to-point connections. This applies in particular when the spring strip contour viewed in the joining direction from the top view is approximately circular. Square, oval or other suitable contours are also conceivable, as long as the latchability with the groove strip described above is guaranteed as claimed.
- connection changes proportionally to the longitudinal extent and therefore, depending on the task, either a large number of point connections and/or non-point connections or a combination of point and non-point connections may be required to meet the requirement for very high stability Links.
- the contours of the cross-sections of tongue and groove are designed to correspond to one another by using locking elements (e.g. locking projections and/or locking recesses) for connecting the spring strip to the groove strip, preferably perpendicularly with respect to the longitudinal directions, so that there is a snap-in connection between the spring strip and groove strip , preferably a forced locking connection, depending on the immersion depth of the tongue in the groove, measured from the top edge of the groove opening, can be produced.
- a locking connection also means that the tongue automatically snaps into place in the groove by means of a snapping process when the tongue is inserted into the groove in the joining direction, a joining force is simultaneously applied in the joining direction and the specified immersion depth is reached.
- the latching elements are preferably configured and matched to one another in such a way that the spring can be pushed into the groove during assembly in the joining direction and positively latched to the grooved strip when the end position is reached.
- the latching elements are preferably additionally configured and matched to one another in such a way that, after the immersion depth has been reached, movement counter to the joining direction is hardly possible, or respectively a grooved strip and Spring strip are fixed transversely to their longitudinal directions.
- the latching elements can preferably also be designed like barbs.
- the latching connection arrangement allows a relative movement of the spring strip in relation to the grooved strip or a relative movement of the grooved strip in relation to the spring strip along one of the two longitudinal directions of the strips. Releasing the connection requires a much greater amount of force than making the connection.
- the fastening areas of the strips lie in a common plane or in two different planes which intersect at an angle between greater than 0 and less than +/-180 degrees. In the first case of the common plane, both fastening areas form a common fastening plane, which is formed horizontally in relation to the joining plane resulting from the joining direction and a longitudinal direction. In the second case, both fastening areas form fastening planes, which can each be formed at an angle deviating from 90 degrees in relation to the joining plane.
- the minimum dimension of the tongue and groove strip depends in particular on the desired release forces which a locking connection arrangement according to the invention is intended to withstand, as well as on the manufacturing method and the usually prevailing tolerance thresholds. Both miniature applications with low stability requirements, for example in model building, and applications with very high stability requirements, for example in building construction or civil engineering, are conceivable.
- the tongue and groove strip is advantageously made from a plastic (eg PA 6 or PA 6.6) by extrusion of this plastic as part of an extrusion process as an endless strand, which can be cut to length in sections to obtain the desired length.
- a plastic eg PA 6 or PA 6.6
- other materials e.g. metals, plastics, natural substances, etc.
- the invention works from the basic principle by means of at least two interlocking profile strips, namely the tongue and groove strip.
- both profile strips snap in stably in the joining direction, so that manual detachment is still possible, but preferably only with a clearly measurable higher force than when joining.
- This allows components to be pre-fixed transversely or perpendicularly to the longitudinal axis of the strips, which significantly simplifies the handling of a component arrangement connected according to the invention, and at the same time enables the components to be adjusted in the longitudinal direction even after the connection has been made.
- the haptics achieved according to the invention when the locking connection arrangement is made/released can prevent accidental manual release of the connection and also premature release if the connection is loaded intentionally or unintentionally.
- the tongue and groove strip can be arranged on any desired component by means of the fastening areas provided in each case, which provides a fastening surface corresponding to the fastening area at least in its edge region.
- the snap-in connection arrangement according to the invention is suitable and can be used for components with a front side or top side or rear side or bottom side that is correspondingly designed at least in one edge area. This preferably includes all of the components already mentioned at the outset. Since the latching connection arrangement according to the invention can be manufactured and handled separately from the components to be connected, suitable standard components can be used and connected. The invention thus simplifies the production of such components, since a connecting means does not have to be provided during their production. The user is free to choose which components he would like to connect using the solution according to the invention.
- the advantages according to the invention are therefore not limited to individual components or groups of components, but can be transferred to combinations of different components or groups of components.
- the assembly and alignment of components connected according to the invention is easy to do due to the above-mentioned adjustability of the components with one another even after the snap-in connection has been made and the components can still be aligned after the connection has been made.
- windshields and/or other vehicle windows and sunroofs could first be latched to the body and only then aligned, without the connection that has already been made being able to accidentally come loose.
- the longitudinal direction of the strips can also serve as a reference line. Gap specifications are also possible depending on the dimensioning of the components according to the invention (e.g. groove width, tongue width, etc.).
- the worker can concentrate on the precise processing of the components, while the latching connection arrangement according to the invention prefixes the components in the desired position in a self-retaining manner. This fixation is largely position-independent, so that depending on the forces that occur and the dimensions of the locking elements, overhead assembly can also be possible, both for the production of surfaces that lie on a common plane and of surfaces that lie on intersecting planes.
- the latching connection arrangement according to the invention thus allows edge and/or corner regions to be formed by means of the component surfaces, in which the component surfaces can be arranged at an angle to one another.
- the fastening areas can also be provided for arranging component surfaces that are not flat, such as components with round contours.
- Appropriately designed adapter elements could be provided for this purpose, the contours of which correspond on the one hand with the contours of the fastening areas and on the other hand also with the contours of the components.
- a Fastening means can be provided for fastening a component, for example a Velcro strip, adhesive tape or the like.
- the fastening areas are particularly preferably designed as preferably planar contact surfaces in order to offer a support surface, in particular for surface elements.
- the advantages according to the invention come into play particularly in the case of surface elements, because the special construction of the snap-in connection arrangement makes it possible to realize surfaces and coverings for building constructions and structures from a large number of surface elements.
- a latching recess also extends along and inside the spring, which includes an undercut and is prepared for latching with the web of a web strip (i.e. with a third strip comprising a web) and which is preferably viewed in the joining direction from the top view is accessible.
- the material of the spring strip can preferably be selected in such a way that the two spring legs behave resiliently, so that they are flexible when the web is inserted into the locking recess, at least transversely to the joining direction and transversely to the longitudinal direction.
- joining direction used in this description refers to a first direction according to which the tongue of the spring strip is to be introduced into the groove of the grooved strip in order to bring about the latching according to the invention.
- the locking recess When inserting the web into the locking recess of the spring, the locking recess can then be at least partially connected to the material of the Web are filled to inhibit the resilience of both legs at least in one direction of movement.
- the web that can be clamped between the spring legs can support the two spring legs against one another and act like a cross brace, which stiffens the spring cross section transversely to the joining direction and at the same time transversely to the longitudinal direction. This has the advantage that the behavior of the spring cross section can be influenced by means of the web.
- a preferably one-piece web strip is included with a web and preferably with a web attachment.
- the web attachment can be connected to the web, with the cross-sectional contours of the web and locking recess of the spring being designed to correspond to one another using locking elements, so that the web can be positively locked with the locking recess at least in sections.
- the bridge attachment particularly preferably extends beyond the latching recess, for example as a handle, and it can preferably also rest on the fastening area.
- the web preferably causes the spring legs to be supported or spread apart, as explained above, which secures the latching between the tongue and groove against manual and/or accidental release.
- the arrangement is designed in such a way that non-destructive release of the latching between the groove and the tongue is only possible after the prior removal of the web strip. Provision is preferably made for the effort required to release the web from the latching recess of the spring to be many times greater than the effort required to insert the web into the spring.
- the invention provides an advantageous solution that combines the advantages of essentially non-releasable connections and releasable connections in the context of assembly and/or disassembly of components.
- the web attachment advantageously also functions as a cover for the snap-in recess of the spring and/or a gap that may exist between the two components after the snap-in connection has been established.
- the web attachment that may protrude from the locking recess can also Take on additional functions and preferably include means for, preferably detachable, arrangement of an electrical component (e.g. LED strip, sensors such as rain sensors, etc.) and/or preferably a conductor for supplying a consumer with energy and/or for transmitting signals include.
- the web can also be electrified and comprise a conductor.
- the web attachment can advantageously also be implemented as a gap seal, for example to meet the requirements of the IP protection classes. For example, splash water protection according to IP classification (e.g. IP 65) could be implemented between the two components if required.
- IP classification e.g. IP 65
- the web strip described above is pivotably connected at least in sections to the tongue strip or to the groove strip, preferably at the transition between the groove or tongue and the fastening area.
- This connection can preferably be realized in one piece within the framework of a (co-)extrusion process, for example, at the same time as the production of the strips, so that the connection behaves according to the properties of a hinge for the pivotable connection of the web strip with the groove strip or for the pivotable connection of the web strip with the female connector.
- the arrangement is dimensioned in such a way that the web can be introduced manually into the latching recess by means of the pivoting movement. This prevents, for example, that the web bar can get lost during assembly work.
- This variant of the invention is also advantageous when working on slopes or at vertical assembly locations.
- the force required to release the locking between the locking recess and the web is many times higher than the force required to produce the locking. This increases the security of the connection, since it can be assumed that accidental loosening of the connection due to external influences that usually occur during assembly is essentially avoided. This also has a positive effect on the feel.
- the longitudinal extent of the spring strip can be a multiple of the longitudinal extent of the grooved strip, with several grooved strips preferably being provided along the longitudinal extent of the spring strip and with preferably at least one web strip being provided, which can be latched with the latching recess of the spring strip.
- Several components can then also be provided on the several slot strips.
- a load-bearing beam could be attached to the attachment area of the single spring strip, with several slats being arranged on the attachment areas of the multiple slot strips, which are to be aligned perpendicularly to the load-bearing beam and are to be attached to the load-bearing beam.
- roof battens could be arranged, aligned and fixed on the rafters of a roof truss without the use of tools.
- the longitudinal extent of the grooved strip can be a multiple of the longitudinal extent of the spring strip, with several spring strips preferably being provided along the longitudinal extent of the grooved strip and with at least one web strip preferably being provided, which can be latched with the latching recesses of the spring strips.
- At least one component is included in the latching connection arrangement.
- this component and the tongue and/or this component and the groove are preferably formed in one piece, so that the fastening area between the tongue or groove and the component is realized by means of the peripheral section of the component.
- This variant is recommended for application-specific designs that require integral components that can be manufactured, for example, using an extrusion process.
- the often higher expenditure of force explained above when loosening the connection is understood to mean a clearly measurable difference in force, which exceeds the usual tolerance limits of the used materials and measuring equipment.
- the dimensioning and design of the latching arrangement according to the invention is carried out in such a way that the difference in the forces required when manually making and loosening the connection with regard to its intensity can be clearly felt by a worker.
- This is preferably also understood to mean that releasing the connection requires at least twice the amount of force compared to establishing the connection.
- the locking elements are dimensioned in such a way that the connection is made with a clearly audible "snapping noise", while the connection is released with less noise.
- the seating and/or snapping of the web strip on the groove strip can serve as an acoustic signal for a secure connection.
- a component according to the invention comprises at least one groove strip as described above and/or at least one spring strip as described above.
- the component is in one piece and can preferably be produced by means of an extrusion process using a suitable extrusion tool.
- the fastening area of the tongue and groove strip is realized by means of a peripheral section of the component (e.g. component contour section), along which the groove and/or tongue is arranged outside the component contours.
- recesses are provided on a preferably used extrusion tool, the contours of which are designed to correspond to the groove cross section and/or to correspond to the tongue cross section.
- Such a component has the advantage that it can be connected without tools to a second, preferably substantially identical component, which also includes such a tongue and groove strip. Both components can then be aligned relative to each other in the longitudinal direction and, after the alignment, preferably additionally fixed by means of the web bar, so that the structure that is also claimed can be realized with high stability.
- the invention also includes an assembly method as claimed, the advantages of which result from the previous explanations.
- joining direction A used in this description refers to a first direction in which the tongue 201 of the spring strip 200 fits into the groove 301 the slotted strip 300 is to be introduced in order to bring about the latching according to the invention.
- transverse direction B used in the description describes a second direction which is aligned transversely, that is to say essentially perpendicularly, to the joining direction A.
- the joining direction A and the transverse direction B span a first plane, which corresponds to the sheet planes of the illustrations, in which sections of arrangements according to the invention are shown.

- the joining direction A and the longitudinal direction C span a second plane, which is arranged perpendicularly to the sheet planes of the figures, in which sections of arrangements according to the invention are shown. This level is also referred to as the joining level.
- longitudinal extent used in the context of the description describes an actually measurable linear expansion in the longitudinal direction C (length) on the strips 100, 200, 300
- transverse extent used in the context of the description describes a linear expansion that can actually be measured on the strips 100, 200, 300 in the transverse direction B (width). If the expansion of the strips 100, 200, 300 in the longitudinal direction C and the expansion of the strips 100, 200, 300 in the transverse direction B are approximately identical, there is a punctiform arrangement. In this case, the length or the width can then correspond to a bar diameter.
- FIG 1 shows a cross-section of a plastic web strip 100 as an example and roughly schematically, which preferably serves to vertically secure the latching connection according to the invention within the joining plane in joining direction A.
- the web strip 100 comprises a web 102, preferably with a web attachment 101, which is preferably integrally connected to the web 102.

- the web 102 can be arranged centrally or eccentrically below the web attachment 101 when viewed in cross section.
- An undercut 105 can be provided on the left-hand and/or right-hand longitudinal side of the web 102, which can be realized, for example, by means of a groove 105 extending along the longitudinal sides.
- a tapering of the material is provided on the underside of the web 106 in the joining direction A. In the example, this is realized by means of an end section that tapers to a point.
- the undercut 105 can also serve to influence the expenditure of force when removing the web 102 from the locking recess 205 of the spring 201, possibly in cooperation with additional locking elements preferably provided within the locking recess 205.

It can be clearly seen how the projections 304 on the groove 301 engage in the indentations 204 on the tongue 201 .

- the tongue 201 is fixed within the groove 301 by means of a clamping effect.
- This clamping effect makes manual removal of tongue 201 from groove 301 more difficult and, depending on the frictional forces that occur, essentially inhibits relative displacement between groove strip 300 and spring strip 200.
- this ratio depends on the specific application and can be configured or controlled freely and possibly also fully automatically and preferably application-specifically within the scope of, for example, an extrusion process for producing the strips 100, 200, 300.

- a corresponding number of web strips 100 can also be provided, which can be latched with the respective latching recess 205 of the spring strips 200 in order to secure the connections made.
- an angle deviating from 90 degrees between the transverse direction B of the spring strip 200 and the longitudinal direction C of the grooved strip 300 can also be realized.
- the contour can also be designed as a latching contour, so that a wide variety of predeterminable angles can be set between the longitudinal extent of the grooved strip 300 and the transverse extent of the spring strip 200.
- the accuracy of the adjustability can be defined by means of the dimensioning of the locking contour.
- figure 7 shows an example of a preferred alternative locking connection arrangement 100, 200, 300 for the realization of point connections.

- the inventive component 203, 303 which here as Surface element is formed, has a top, a bottom, a left and a right outside and two end faces.
- it can be a floor construction 400 or a wall construction 400, e.g. a screen wall 400 for properties or a wall cladding 400.

- the respective component contour sections or peripheral sections of the component simultaneously form the fastening areas 202, 302, by means of which the groove 301 or the tongue 201 is arranged on the component 203, 303.

- the components 203, 303 thus remain adjustable in the longitudinal direction of the strips 200, 300. However, a movement deviating from the longitudinal direction is made more difficult.
- Fastening areas 202, 302, which are only indicated, of the strips 200, 300 latched to one another lie on a common plane, as a result of which large and preferably flat surfaces can be realized by means of a large number of component arrangements according to the invention.

- the attachment areas 202, 302 lie at least partially within the contours of the components 203, 303 and the groove 301 and the spring 201 are outside the contours of the components 203, 303. Because of the one-piece shown, the fastening areas 202, 302 of the strips 200, 300 merge with the peripheral sections of the components 203, 303 shown.

Description
Die vorliegende Erfindung betrifft eine Rastverbindungsanordnung zur Verbindung von Bauteilen sowie ein Bauteil, einen Baukörper und ein Montageverfahren.The present invention relates to a snap-in connection arrangement for connecting components, as well as a component, a structure and an assembly method.
Der Anwendungsbereich der erfindungsgemäßen Lösung umfasst alle denkbaren Aufgabenstellungen, bei denen zumindest zwei Bauteile miteinander verbunden werden, insbesondere Flächenelemente wie Fußbodenelemente, Fassadenelemente, Dachelemente, Fahrzeugbauteile, Sichtschutzelemente und dergleichen. Hierbei kann es sich auch um eine Kombination aus einem Flächenelement mit sonstigen im Handel erhältlichen Bauteilen handeln, wie beispielsweise Profilelemente, Leistenelemente, Rahmenelemente, Stangenelemente und dergleichen. Zur Herstellung von Verbindungen zwischen Flächenelementen sind beispielsweise sogenannte Nut- und Federverbindungen bekannt, wie sie im Dokument
Um dem entgegenzuwirken, wurden rastende Verbindungen entwickelt. So zeigt beispielsweise das Dokument
Eine Leiste ist mit einer längsdurchlaufenden Nut versehen, und die andere Leiste ist mit einem längsdurchlaufenden und in die Nut eingreifenden Steg versehen.One bar is provided with a longitudinal groove, and the other bar is provided with a longitudinal bar engaging in the groove.
Eine vergleichbare Lösung mit einer Nut-Feder-Verbindung ist im Dokument
Es ist wünschenswert, alternative und möglichst flexible Lösungen verfügbar zu haben, welche universell einsetzbar sind. Die Montage sowie die Ausrichtung der Bauteile sollten während der Montage bei möglichst hoher Präzision leicht von der Hand gehen.It is desirable to have alternative solutions that are as flexible as possible and that can be used universally. The assembly and the alignment of the components should be easy to do during assembly with the greatest possible precision.
Erfindungsgemäß wird eine Rastverbindungsanordnung wie beansprucht vorgeschlagen. Zusätzlich wird ein erfindungsgemäßes Bauteil und ein erfindungsgemäßer Baukörper und ein erfindungsgemäßes Montageverfahren vorgeschlagen und beansprucht. Als Bauteil wird jeglicher Körper aufgefasst, welcher mit mindestens einem weiteren gleichartig oder unterschiedlich aufgebauten Körper verbunden werden kann, wobei jeder der Körper zumindest eine Vorderseite und eine Rückseite sowie mehrere Stirnseiten aufweist, an denen eine Leiste anordenbar ist.According to the invention, a latching connection arrangement is proposed as claimed. In addition, a component according to the invention and a structure according to the invention and an assembly method according to the invention are proposed and claimed. Any body that can be connected to at least one other body of the same or different structure is considered to be a component, with each body having at least one front and one rear and a plurality of front sides on which a strip can be arranged.
Die erfindungsgemäße Rastverbindungsanordnung umfasst eine Nutleiste (d.h. eine erste Leiste mit einer Nut) mit einem, vorzugsweise unmittelbar neben und parallel zur Nut, das heißt entlang der Nut, verlaufenden, ersten Befestigungsbereich. Die Nut dient zur Aufnahme der Feder einer Federleiste, welche weiter unten erläutert wird. Der Befestigungsbereich dient zur Anordnung der Nutleiste entlang eines Umfangsabschnittes eines Bauteils, so dass die Nut idealerweise entlang des Bauteilrandes und gut zugänglich neben der Bauteiloberfläche verläuft. Das Bauteil kann ein quaderförmiges Bauteil sein, vorzugsweise ein Flächenelement, wie eine Scheibe, ein Paneel, eine Verkleidung, eine Platte, eine Latte und/oder eine Leiste, ein Dach-, Wand- und Bodenelement, ein Solarpanel oder dergleichen. Die Nutleiste erstreckt sich in eine erste Längsrichtung, vorzugsweise quer, bevorzugt senkrecht, zum Nutleistenquerschnitt, und auch in eine erste Querrichtung.The latching connection arrangement according to the invention comprises a grooved strip (ie a first strip with a groove) with a first fastening region which preferably runs directly next to and parallel to the groove, ie along the groove. The groove serves to accommodate the tongue of a spring strip, which is explained further below. The fastening area is used for arranging the slot strip along a peripheral section of a component, so that the slot ideally runs along the edge of the component and is easily accessible next to the surface of the component. The component can be a cuboid component, preferably a surface element, such as a pane, a panel, a cladding, a slab, a slat and/or a strip, a roof, wall and floor element, a solar panel or the like. The slot strip extends in a first longitudinal direction, preferably transversely, preferably perpendicularly, to the slot strip cross section, and also in a first transverse direction.
Die Längserstreckung (= Leistenlänge in Längsrichtung) der Nutleiste kann um ein Vielfaches größer sein als die Quererstreckung (= Leistenbreite in Querrichtung, insbesondere senkrecht zur Längsrichtung ausgerichtet), so dass der typische Leistencharakter entsteht. Zur Realisierung von punktuellen Verbindungen kann die Längserstreckung der Quererstreckung in etwa entsprechen, ggf. auch geringer ausfallen. Insbesondere zur Realisierung von punktuellen Verbindungen kann die Längserstreckung bzw. die Quererstreckung auch einem Kreisdurchmesser entsprechen. Dies gilt insbesondere dann, wenn die in Fügerichtung aus der Draufsicht betrachtete Nutleistenkontur in etwa kreisförmig verläuft. Auch quadratische, ovale oder sonstige geeignete Konturen sind denkbar, solange die Verrastbarkeit mit der nachfolgend beschriebenen Federleiste wie beansprucht gewährleistet ist.The longitudinal extension (= length of the strip in the longitudinal direction) of the slotted strip can be many times greater than the transverse extension (= width of the strip in the transverse direction, in particular aligned perpendicularly to the longitudinal direction), so that the typical strip character is created. In order to implement punctiform connections, the longitudinal extension can approximately correspond to the transverse extension, and possibly also be smaller. The longitudinal extent or the transverse extent can also correspond to a circular diameter, in particular for the realization of point-to-point connections. This applies in particular when the groove strip contour viewed in the joining direction from the top view runs approximately circularly. Square, oval or other suitable contours are also conceivable, as long as the latchability with the spring strip described below is guaranteed as claimed.
Die erfindungsgemäße Rastverbindungsanordnung umfasst zusätzlich eine Federleiste (d.h. eine zweite Leiste mit einer Feder) mit einem, vorzugsweise unmittelbar neben und parallel zur Feder, das heißt entlang der Feder, verlaufenden, zweiten Befestigungsbereich. Die Feder ist zur Einbringung in die Nut der oben beschriebenen Nutleiste vorgesehen. Der Befestigungsbereich dient zur Anordnung der Federleiste entlang eines Umfangsabschnittes eines Bauteils, so dass die Feder idealerweise entlang des Bauteilrandes und gut zugänglich neben der Bauteiloberfläche verläuft. Die Federleiste erstreckt sich in eine zweite Längsrichtung, vorzugsweise quer, bevorzugt senkrecht, zum Federleistenquerschnitt, und auch in eine zweite Querrichtung. Auch die Längserstreckung der Federleiste kann um ein Vielfaches größer sein als die Quererstreckung, so dass der typische Leistencharakter entsteht. Zur Realisierung von punktuellen Verbindungen kann jedoch die Länge der Federleiste auch in etwa der Breite des Federleistenquerschnittes entsprechen oder auch geringer ausfallen. Insbesondere zur Realisierung von punktuellen Verbindungen kann die Längserstreckung bzw. die Quererstreckung auch einem Kreisdurchmesser entsprechen. Dies gilt insbesondere dann, wenn die in Fügerichtung aus der Draufsicht betrachtete Federleistenkontur in etwa kreisförmig verläuft. Auch quadratische, ovale oder sonstige geeignete Konturen sind denkbar, solange die Verrastbarkeit mit der oben beschriebenen Nutleiste wie beansprucht gewährleistet ist.The snap-in connection arrangement according to the invention additionally comprises a spring strip (ie a second strip with a spring) with a second fastening area, preferably running directly next to and parallel to the spring, ie along the spring. The tongue is intended to be inserted into the groove of the groove strip described above. The fastening area is used for arranging the spring strip along a peripheral section of a component, so that the spring ideally runs along the edge of the component and is easily accessible next to the surface of the component. The spring strip extends in a second longitudinal direction, preferably transversely, preferably perpendicularly, to the spring strip cross section, and also in a second transverse direction. The longitudinal extent of the spring strip can also be many times greater than the transverse extent, so that the typical strip character is created. In order to implement point-to-point connections, however, the length of the spring strip can also correspond approximately to the width of the spring strip cross-section or be less. The longitudinal extent or the transverse extent can also correspond to a circular diameter, in particular for the realization of point-to-point connections. This applies in particular when the spring strip contour viewed in the joining direction from the top view is approximately circular. Square, oval or other suitable contours are also conceivable, as long as the latchability with the groove strip described above is guaranteed as claimed.
Zusammenfassend gilt für punktuelle Verbindungen bevorzugt im Rahmen der fertigungsüblichen Toleranzen für die Nutleiste und/oder die Federleiste:
Zu beachten ist dabei, dass sich die Stabilität der Verbindung proportional zur Längserstreckung verändert und damit für das Erfordernis einer sehr hohen Stabilität je nach Aufgabenstellung entweder eine Vielzahl von punktuellen Verbindungen erforderlich werden kann und/oder nicht punktuelle Verbindungen oder eine Kombination aus punktuellen und nicht punktuellen Verbindungen.It should be noted that the stability of the connection changes proportionally to the longitudinal extent and therefore, depending on the task, either a large number of point connections and/or non-point connections or a combination of point and non-point connections may be required to meet the requirement for very high stability Links.
Erfindungsgemäß sind die Konturen der Querschnitte von Feder und Nut zueinander korrespondierend mittels Verwendung von Rastelementen (z.B. Rastvorsprünge und/oder Rastausnehmungen) zum, in Bezug auf die Längsrichtungen vorzugsweise senkrechten, Verbinden der Federleiste mit der Nutleiste ausgebildet, so dass zwischen Federleiste und Nutleiste eine Rastverbindung, vorzugsweise eine Zwangsrastverbindung, abhängig von der Eintauchtiefe der Feder in die Nut, gemessen ab Oberkante Nutöffnung, herstellbar ist. Unter einer Rastverbindung wird u.a. auch verstanden, dass die Feder in der Nut mittels eines Schnappvorgangs selbsttätig einrastet, wenn die Feder in die Nut in Fügerichtung eingeführt wird, gleichzeitig in Fügerichtung eine Fügekraft aufgebracht wird und die vorgegebene Eintauchtiefe erreicht ist. Die Rastelemente sind dabei vorzugsweise derart ausgestaltet und aufeinander abgestimmt, dass die Feder bei der Montage in Fügerichtung in die Nut eingeschoben werden kann und bei Erreichen der Endstellung zwangsläufig mit der Nutleiste verrastet. Die Rastelemente sind dabei vorzugsweise zusätzlich derart ausgestaltet und aufeinander abgestimmt, dass nach Erreichen der Eintauchtiefe eine Bewegung entgegen der Fügerichtung kaum mehr möglich ist bzw. Nutleiste und Federleiste quer zu ihren Längsrichtungen festgelegt sind. Hierzu können die Rastelemente vorzugsweise auch widerhakenartig ausgebildet sein.According to the invention, the contours of the cross-sections of tongue and groove are designed to correspond to one another by using locking elements (e.g. locking projections and/or locking recesses) for connecting the spring strip to the groove strip, preferably perpendicularly with respect to the longitudinal directions, so that there is a snap-in connection between the spring strip and groove strip , preferably a forced locking connection, depending on the immersion depth of the tongue in the groove, measured from the top edge of the groove opening, can be produced. A locking connection also means that the tongue automatically snaps into place in the groove by means of a snapping process when the tongue is inserted into the groove in the joining direction, a joining force is simultaneously applied in the joining direction and the specified immersion depth is reached. The latching elements are preferably configured and matched to one another in such a way that the spring can be pushed into the groove during assembly in the joining direction and positively latched to the grooved strip when the end position is reached. The latching elements are preferably additionally configured and matched to one another in such a way that, after the immersion depth has been reached, movement counter to the joining direction is hardly possible, or respectively a grooved strip and Spring strip are fixed transversely to their longitudinal directions. For this purpose, the latching elements can preferably also be designed like barbs.
Nach der Verrastung bleiben Nutleiste und Federleiste dennoch lösbar miteinander verbunden. Die erfindungsgemäße Rastverbindungsanordnung lässt eine relative Bewegung der Federleiste gegenüber der Nutleiste oder eine relative Bewegung der Nutleiste gegenüber der Federleiste entlang einer der beiden Längsrichtungen der Leisten zu. Das Lösen der Verbindung erfordert einen wesentlich höheren Kraftaufwand als das Herstellen der Verbindung. Die Befestigungsbereiche der Leisten liegen nach Herstellung der Rastverbindung in einer gemeinsamen Ebene oder in zwei verschiedenen Ebenen, welche einander in einem Winkel zwischen größer 0 und kleiner +/- 180 Grad schneiden. Im ersteren Fall der gemeinsamen Ebene bilden beide Befestigungsbereiche eine gemeinsame Befestigungsebene, welche waagerecht in Bezug auf die sich aus der Fügerichtung und einer Längsrichtung ergebende Fügeebene ausgebildet ist. Im zweiten Fall bilden beide Befestigungsbereiche Befestigungsebenen, welche jeweils in einem Winkel abweichend von 90 Grad in Bezug auf die Fügeebene ausgebildet sein können.After locking, the tongue and groove strip remain detachably connected to each other. The latching connection arrangement according to the invention allows a relative movement of the spring strip in relation to the grooved strip or a relative movement of the grooved strip in relation to the spring strip along one of the two longitudinal directions of the strips. Releasing the connection requires a much greater amount of force than making the connection. After the locking connection has been made, the fastening areas of the strips lie in a common plane or in two different planes which intersect at an angle between greater than 0 and less than +/-180 degrees. In the first case of the common plane, both fastening areas form a common fastening plane, which is formed horizontally in relation to the joining plane resulting from the joining direction and a longitudinal direction. In the second case, both fastening areas form fastening planes, which can each be formed at an angle deviating from 90 degrees in relation to the joining plane.
Die Minimalabmessung der Nutleiste und/oder der Federleiste richtet sich insbesondere nach den gewünschten Lösekräften, welchen eine erfindungsgemäße Rastverbindungsanordnung standhalten soll, sowie nach der Fertigungsmethode und den üblicherweise vorherrschenden Toleranzschwellen. Denkbar sind sowohl Miniaturanwendungen mit geringen Stabilitätsanforderungen, beispielsweise im Modellbau, als auch Anwendungen mit sehr hohen Anforderungen an die Stabilität, beispielsweise im Hochbau oder im Tiefbau.The minimum dimension of the tongue and groove strip depends in particular on the desired release forces which a locking connection arrangement according to the invention is intended to withstand, as well as on the manufacturing method and the usually prevailing tolerance thresholds. Both miniature applications with low stability requirements, for example in model building, and applications with very high stability requirements, for example in building construction or civil engineering, are conceivable.
Die Nutleiste und/oder die Federleiste wird vorteilhafterweise aus einem Kunststoff (z.B. PA 6 oder PA 6.6) mittels Extrusion dieses Kunststoffes im Rahmen eines Extrusionsverfahrens als Endlosstrang hergestellt, welcher abschnittsweise abgelängt werden kann, um die gewünschte Längserstreckung zu erhalten. Mittels Ko-Extrusion können weitere Materialien (z.B. Metalle, Kunststoffe, Naturstoffe, etc.) während der Extrusion eingearbeitet werden, um beispielsweise die Stabilität, Flexibilität zu beeinflussen und weitere Anwendungsfelder zu erschließen. Dies ermöglicht es, die Leisten kundenspezifisch oder als Standardprodukt sehr preiswert herzustellen und entsprechend günstig am Markt anzubieten.The tongue and groove strip is advantageously made from a plastic (eg PA 6 or PA 6.6) by extrusion of this plastic as part of an extrusion process as an endless strand, which can be cut to length in sections to obtain the desired length. By means of co-extrusion, other materials (e.g. metals, plastics, natural substances, etc.) can be incorporated during extrusion, for example to increase stability and flexibility influence and open up further fields of application. This makes it possible to manufacture the strips very inexpensively according to customer specifications or as a standard product and to offer them on the market at correspondingly low prices.
Vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche sowie der nachfolgenden Beschreibung.Advantageous configurations are the subject of the dependent claims and the following description.
Die Erfindung arbeitet vom Grundprinzip her mittels wenigstens zweier ineinandergreifender Profilleisten, nämlich der Nutleiste und der Federleiste. Bei der Herstellung der erfindungsgemäßen Rastverbindunganordnung verrasten beide Profilleisten in Fügerichtung stabil, so dass zwar ein manuelles Lösen noch möglich ist, vorzugsweise jedoch nur mit einem deutlich messbaren höheren Kraftaufwand als beim Zusammenfügen. Hierdurch wird eine Vorfixierung von Bauteilen quer oder senkrecht zur Längsachse der Leisten ermöglicht, was die Handhabung einer erfindungsgemäß verbundenen Bauteileanordnung deutlich vereinfacht, und andererseits zugleich eine Justierung der Bauteile in Längsrichtung auch noch nach dem Herstellen der Verbindung ermöglicht. Die erfindungsgemäß erzielte Haptik beim Herstellen/Lösen der Rastverbindungsordnung kann ein versehentliches manuelles Lösen der Verbindung und außerdem auch ein vorzeitiges Lösen bei beabsichtigter oder unbeabsichtigter Belastung der Verbindung verhindern.The invention works from the basic principle by means of at least two interlocking profile strips, namely the tongue and groove strip. During the production of the snap-in connection arrangement according to the invention, both profile strips snap in stably in the joining direction, so that manual detachment is still possible, but preferably only with a clearly measurable higher force than when joining. This allows components to be pre-fixed transversely or perpendicularly to the longitudinal axis of the strips, which significantly simplifies the handling of a component arrangement connected according to the invention, and at the same time enables the components to be adjusted in the longitudinal direction even after the connection has been made. The haptics achieved according to the invention when the locking connection arrangement is made/released can prevent accidental manual release of the connection and also premature release if the connection is loaded intentionally or unintentionally.
Außerdem können Nutleiste und Federleiste mittels der jeweils bereitgestellten Befestigungsbereiche an jedem beliebigen Bauteil angeordnet werden, welches zumindest an seinem Randbereich eine zum Befestigungsbereich korrespondierende Befestigungsfläche bereitstellt. Insofern ist die erfindungsgemäße Rastverbindungsanordnung für Bauteile mit einer zumindest in einem Randbereich entsprechend ausgebildeten Vorderseite bzw. Oberseite oder Rückseite bzw. Unterseite geeignet und verwendbar. Hierunter fallen bevorzugt sämtliche eingangs bereits erwähnten Bauteile. Da die erfindungsgemäße Rastverbindunganordnung separat von den zu verbindenden Bauteilen herstellbar und handelbar ist, können geeignete Standardbauelemente verwendet und verbunden werden. Die Erfindung vereinfacht somit die Herstellung solcher Bauteile, da bei deren Herstellung ein Verbindungsmittel nicht vorgesehen werden muss. Der Anwender kann frei wählen, welche Bauteile er mittels der erfindungsgemäßen Lösung verbinden möchte. Die erfindungsgemäßen Vorteile sind damit nicht auf einzelne Bauteile oder Bauteilgruppen beschränkt, sondern auf Kombinationen von unterschiedlichen Bauteilen oder Bauteilgruppen übertragbar.In addition, the tongue and groove strip can be arranged on any desired component by means of the fastening areas provided in each case, which provides a fastening surface corresponding to the fastening area at least in its edge region. In this respect, the snap-in connection arrangement according to the invention is suitable and can be used for components with a front side or top side or rear side or bottom side that is correspondingly designed at least in one edge area. This preferably includes all of the components already mentioned at the outset. Since the latching connection arrangement according to the invention can be manufactured and handled separately from the components to be connected, suitable standard components can be used and connected. The invention thus simplifies the production of such components, since a connecting means does not have to be provided during their production. The user is free to choose which components he would like to connect using the solution according to the invention. The advantages according to the invention are therefore not limited to individual components or groups of components, but can be transferred to combinations of different components or groups of components.
Hinzu kommt, dass die Montage und Ausrichtung erfindungsgemäß verbundener Bauteile aufgrund der oben erwähnten Ausrichtbarkeit der Bauteile untereinander auch nach Herstellung der Rastverbindung leicht von der Hand geht und die Bauteile auch nach Herstellung der Verbindung noch ausgerichtet werden können. Beispielsweise Windschutzscheiben und/oder sonstige Fahrzeugscheiben sowie Sonnendächer könnten zunächst mit der Karosserie verrastet und dann erst ausgerichtet werden, ohne dass sich die bereits hergestellte Verbindung versehentlich lösen kann. Bei der Ausrichtung kann die Längsrichtung der Leisten außerdem als Referenzlinie dienen. Spaltmaßvorgaben sind je nach Dimensionierung der erfindungsgemäßen Komponenten (z.B. Nutbreite, Federbreite etc.) ebenfalls möglich. Der Werker kann sich auf das präzise Verarbeiten der Bauteile konzentrieren, während die erfindungsgemäße Rastverbindungsanordnung die Bauteile in der gewünschten Position selbsthaltend vorfixiert. Diese Fixierung ist weitestgehend lageunabhängig, so dass je nach auftretenden Kräften und Dimensionierungen der Rastelemente auch eine Überkopfmontage möglich sein kann, sowohl zur Herstellung von Oberflächen, die auf einer gemeinsamen Ebene liegen, als auch von Oberflächen, die auf sich schneidenden Ebenen liegen. Die erfindungsgemäße Rastverbindungsanordnung lässt es somit zu, dass mittels der Bauteiloberflächen Rand- und/oder Eckbereiche ausgebildet werden können, bei denen die Bauteiloberflächen winkelig zueinander angeordnet sein können.In addition, the assembly and alignment of components connected according to the invention is easy to do due to the above-mentioned adjustability of the components with one another even after the snap-in connection has been made and the components can still be aligned after the connection has been made. For example, windshields and/or other vehicle windows and sunroofs could first be latched to the body and only then aligned, without the connection that has already been made being able to accidentally come loose. When aligning, the longitudinal direction of the strips can also serve as a reference line. Gap specifications are also possible depending on the dimensioning of the components according to the invention (e.g. groove width, tongue width, etc.). The worker can concentrate on the precise processing of the components, while the latching connection arrangement according to the invention prefixes the components in the desired position in a self-retaining manner. This fixation is largely position-independent, so that depending on the forces that occur and the dimensions of the locking elements, overhead assembly can also be possible, both for the production of surfaces that lie on a common plane and of surfaces that lie on intersecting planes. The latching connection arrangement according to the invention thus allows edge and/or corner regions to be formed by means of the component surfaces, in which the component surfaces can be arranged at an angle to one another.
Die Befestigungsbereiche können auch zur Anordnung nicht eben ausgebildeter Bauteiloberflächen vorgesehen sein, wie beispielsweise Bauteile mit runden Konturen. Hierzu könnten entsprechend ausgebildete Adapterelemente vorgesehen sein, deren Konturen einerseits mit den Konturen der Befestigungsbereiche und andererseits auch mit den Konturen der Bauteile korrespondieren. An den Befestigungsbereichen kann ein Befestigungsmittel zur Befestigung eines Bauelementes vorgesehen sein, beispielsweise ein Klettband, Klebeband oder dergleichen.The fastening areas can also be provided for arranging component surfaces that are not flat, such as components with round contours. Appropriately designed adapter elements could be provided for this purpose, the contours of which correspond on the one hand with the contours of the fastening areas and on the other hand also with the contours of the components. At the attachment areas, a Fastening means can be provided for fastening a component, for example a Velcro strip, adhesive tape or the like.
Besonders bevorzugt sind die Befestigungsbereiche als, vorzugsweise ebene, Anlageflächen ausgebildet, um eine Auflagefläche insbesondere für Flächenelemente anzubieten. Besonders bei Flächenelementen kommen die erfindungsgemäßen Vorteile zum Tragen, denn die spezielle Konstruktion der Rastverbindungsanordnung ermöglicht es, Oberflächen und Verkleidungen für Baukonstruktionen und Baukörper aus einer Vielzahl von Flächenelementen zu realisieren.The fastening areas are particularly preferably designed as preferably planar contact surfaces in order to offer a support surface, in particular for surface elements. The advantages according to the invention come into play particularly in the case of surface elements, because the special construction of the snap-in connection arrangement makes it possible to realize surfaces and coverings for building constructions and structures from a large number of surface elements.
Erfindungsgemäß ist vorgesehen, dass sich auch entlang und innerhalb der Feder eine Rastausnehmung erstreckt, welche eine Hinterschneidung umfasst und zur Verrastung mit dem Steg einer Stegleiste (d.h mit einer dritten Leiste, umfassend einen Steg) vorbereitet ist und die vorzugsweise in Fügerichtung aus der Draufsicht betrachtet zugänglich ist. Hierdurch wird ein Federquerschnitt (z.B. U-förmig oder V-förmig) mit zwei sich gegenüberliegenden Federschenkeln realisiert, zwischen denen der Steg anordenbar ist. Das Material der Federleiste kann bevorzugt derart gewählt werden, dass sich die beiden Federschenkel federnd verhalten, so dass diese beim Einführen des Steges in die Rastausnehmung zumindest quer zur Fügerichtung und quer zur Längsrichtung betrachtet nachgiebig sind. Diese Nachgiebigkeit bewirkt, dass sich die Federschenkel beim Herstellen der Verbindung zwischen Steg und Rastausnehmung zunächst spreizen und nach dem Herstellen der Verbindung (d.h. nach dem Verrasten von Steg und Rastausnehmung) und bei Erreichen der für die Verrastung erforderlichen Eintauchtiefe aufgrund der Elastizität im Wesentlichen wieder ihre Ausgangsposition einnehmen.According to the invention, it is provided that a latching recess also extends along and inside the spring, which includes an undercut and is prepared for latching with the web of a web strip (i.e. with a third strip comprising a web) and which is preferably viewed in the joining direction from the top view is accessible. This creates a spring cross-section (e.g. U-shaped or V-shaped) with two opposite spring legs, between which the web can be arranged. The material of the spring strip can preferably be selected in such a way that the two spring legs behave resiliently, so that they are flexible when the web is inserted into the locking recess, at least transversely to the joining direction and transversely to the longitudinal direction. This resilience causes the spring legs to initially spread when the connection between the web and the locking recess is established and, after the connection has been made (i.e. after the web and the locking recess have been locked) and when the immersion depth required for the locking is reached, due to the elasticity, they essentially regain their position take the starting position.
Der im Rahmen dieser Beschreibung verwendete Begriff Fügerichtung bezieht sich auf eine erste Richtung, gemäß derer die Feder der Federleiste in die Nut der Nutleiste einzubringen ist, um die erfindungsgemäße Verrastung herbeizuführen.The term joining direction used in this description refers to a first direction according to which the tongue of the spring strip is to be introduced into the groove of the grooved strip in order to bring about the latching according to the invention.
Beim Einfügen des Steges in die Rastausnehmung der Feder kann die Rastausnehmung anschließend zumindest abschnittsweise mit dem Material des Steges gefüllt werden, um die Nachgiebigkeit beider Schenkel zumindest in einer Bewegungsrichtung zu hemmen. Der zwischen den Federschenkeln einklemmbare Steg kann beide Federschenkel gegeneinander abstützen und wie eine Querstrebe wirken, welche den Federquerschnitt quer zur Fügerichtung und gleichzeitig quer zur Längsrichtung versteift. Dies hat den Vorteil, dass das Verhalten des Federquerschnittes mittels des Steges beeinflussbar wird.When inserting the web into the locking recess of the spring, the locking recess can then be at least partially connected to the material of the Web are filled to inhibit the resilience of both legs at least in one direction of movement. The web that can be clamped between the spring legs can support the two spring legs against one another and act like a cross brace, which stiffens the spring cross section transversely to the joining direction and at the same time transversely to the longitudinal direction. This has the advantage that the behavior of the spring cross section can be influenced by means of the web.
Bei einer bevorzugten Ausführungsform der erfindungsgemäßen Rastverbindungsanordnung ist eine, vorzugsweise einstückige, Stegleiste mit einem Steg und vorzugsweise mit einem Stegaufsatz umfasst. Der Stegaufsatz kann mit dem Steg verbunden sein, wobei die Querschnittskonturen von Steg und Rastausnehmung der Feder zueinander korrespondierend unter Verwendung von Rastelementen ausgebildet sind, so dass der Steg zumindest abschnittsweise formschlüssig mit der Rastausnehmung verrastbar ist. Besonders bevorzugt erstreckt sich der Stegaufsatz über die Rastausnehmung hinaus, beispielsweise als Griffstück, vorzugsweise kann er dabei auch auf dem Befestigungsbereich aufliegen. Der Steg bewirkt bevorzugt ein Abstützen oder Spreizen der Federschenkel wie weiter oben erläutert, welches die Verrastung zwischen Nut und Feder gegen ein manuelles und/oder versehentliches Lösen absichert. Idealerweise ist die Anordnung derart konzipiert, dass ein zerstörungsfreies Lösen der Verrastung zwischen Nut und der Feder erst nach dem vorherigen Entfernen der Stegleiste möglich ist. Bevorzugt ist vorgesehen, dass für das Lösen des Steges aus der Rastausnehmung der Feder ein Kraftaufwand erforderlich ist, welcher um ein Vielfaches höher ist als der zum Einbringen des Steges in die Feder erforderliche Kraftaufwand.In a preferred embodiment of the latching connection arrangement according to the invention, a preferably one-piece web strip is included with a web and preferably with a web attachment. The web attachment can be connected to the web, with the cross-sectional contours of the web and locking recess of the spring being designed to correspond to one another using locking elements, so that the web can be positively locked with the locking recess at least in sections. The bridge attachment particularly preferably extends beyond the latching recess, for example as a handle, and it can preferably also rest on the fastening area. The web preferably causes the spring legs to be supported or spread apart, as explained above, which secures the latching between the tongue and groove against manual and/or accidental release. Ideally, the arrangement is designed in such a way that non-destructive release of the latching between the groove and the tongue is only possible after the prior removal of the web strip. Provision is preferably made for the effort required to release the web from the latching recess of the spring to be many times greater than the effort required to insert the web into the spring.
Kombiniert mit der Stegleiste stellt die Erfindung eine vorteilhafte Lösung zur Verfügung, welche im Rahmen einer Montage und/oder Demontage von Bauteilen die Vorteile von im Wesentlichen nicht lösbaren Verbindungen und lösbaren Verbindungen vereint. Der Stegaufsatz fungiert vorteilhafterweise zusätzlich als Abdeckung für die Rastausnehmung der Feder und/oder eines nach dem Herstellen der Rastverbindung gegebenenfalls vorherrschenden Spaltes zwischen beiden Bauteilen. Der gegebenenfalls aus der Rastausnehmung überstehende Stegaufsatz kann auch Zusatzfunktionen übernehmen und vorzugsweise Mittel zur, vorzugsweise lösbaren, Anordnung eines elektrischen Bauelementes (z.B. LED-Leiste, Sensorik wie beispielsweise Regensensoren, o.ä.) umfassen und/oder vorzugsweise einen Leiter zur Versorgung eines Verbrauchers mit Energie und/oder zur Übertragung von Signalen umfassen. Auch kann der Steg kann elektrifiziert sein und einen Leiter umfassen. Der Stegaufsatz kann vorteilhafterweise zusätzlich als Spaltabdichtung realisiert sein, um beispielsweise den Anforderungen der IP-Schutzklassen gerecht zu werden. So könnte bei Bedarf zwischen beiden Bauteilen beispielsweise ein Spritzwasserschutz gemäß IP-Klassifikation (bspw. IP 65) realisiert werden.Combined with the web strip, the invention provides an advantageous solution that combines the advantages of essentially non-releasable connections and releasable connections in the context of assembly and/or disassembly of components. The web attachment advantageously also functions as a cover for the snap-in recess of the spring and/or a gap that may exist between the two components after the snap-in connection has been established. The web attachment that may protrude from the locking recess can also Take on additional functions and preferably include means for, preferably detachable, arrangement of an electrical component (e.g. LED strip, sensors such as rain sensors, etc.) and/or preferably a conductor for supplying a consumer with energy and/or for transmitting signals include. The web can also be electrified and comprise a conductor. The web attachment can advantageously also be implemented as a gap seal, for example to meet the requirements of the IP protection classes. For example, splash water protection according to IP classification (e.g. IP 65) could be implemented between the two components if required.
Ganz besonders bevorzugt ist die zuvor beschriebene Stegleiste zumindest abschnittsweise schwenkbar mit der Federleiste oder mit der Nutleiste verbunden, bevorzugt am Übergang zwischen Nut bzw. Feder und dem Befestigungsbereich. Diese Verbindung kann vorzugsweise einstückig im Rahmen eines beispielsweise (Ko-) Extrusionsverfahrens gleichzeitig mit der Herstellung der Leisten realisiert werden, so dass sich die Verbindung verhält gemäß den Eigenschaften eines Scharniers zum schwenkbeweglichen Verbinden der Stegleiste mit der Nutleiste oder zum schwenkbeweglichen Verbinden der Stegleiste mit der Federleiste. Die Anordnung ist dabei derart dimensioniert, dass der Steg mittels der Schwenkbewegung in die Rastausnehmung manuell einbringbar ist. Dies verhindert beispielsweise, dass die Stegleiste bei den Montagearbeiten verloren gehen kann. Auch bei Arbeiten an Schrägen oder an senkrechten Montageorten ist diese Variante der Erfindung vorteilhaft.Very particularly preferably, the web strip described above is pivotably connected at least in sections to the tongue strip or to the groove strip, preferably at the transition between the groove or tongue and the fastening area. This connection can preferably be realized in one piece within the framework of a (co-)extrusion process, for example, at the same time as the production of the strips, so that the connection behaves according to the properties of a hinge for the pivotable connection of the web strip with the groove strip or for the pivotable connection of the web strip with the female connector. The arrangement is dimensioned in such a way that the web can be introduced manually into the latching recess by means of the pivoting movement. This prevents, for example, that the web bar can get lost during assembly work. This variant of the invention is also advantageous when working on slopes or at vertical assembly locations.
Vorteilhafterweise ist vorgesehen, dass der erforderliche Kraftaufwand zum Lösen der Verrastung zwischen der Rastausnehmung und dem Steg um ein Vielfaches höher ist als der Kraftaufwand zum Herstellen der Verrastung. Dies erhöht die Sicherheit der Verbindung, da davon auszugehen ist, dass ein versehentliches Lösen der Verbindung durch bei der Montage üblicherweise auftretende äußere Einflüsse im Wesentlichen vermieden wird. Auch auf die Haptik wirkt sich dies positiv aus.Advantageously, it is provided that the force required to release the locking between the locking recess and the web is many times higher than the force required to produce the locking. This increases the security of the connection, since it can be assumed that accidental loosening of the connection due to external influences that usually occur during assembly is essentially avoided. This also has a positive effect on the feel.
Bei einer bevorzugten Ausführungsform kann die Längserstreckung der Federleiste ein Vielfaches der Längserstreckung der Nutleiste betragen, wobei vorzugsweise entlang der Längserstreckung der Federleiste mehrere Nutleisten vorgesehen sind und wobei vorzugsweise zumindest eine Stegleiste vorgesehen ist, welche mit der Rastausnehmung der Federleiste verrastbar ist. An den mehreren Nutleisten können dann auch mehrere Bauteile vorgesehen sein. Beispielsweise könnte am Befestigungsbereich der einzigen Federleiste ein tragender Balken angebracht sein, wobei an den Befestigungsbereichen der mehreren Nutleisten mehrere Latten angeordnet sind, welche senkrecht zum tragenden Balken auszurichten sind und am tragenden Balken zu befestigen sind. Derart könnten beispielsweise Dachlatten an den Sparren eines Dachstuhls werkzeugfrei angeordnet, ausgerichtet und fixiert werden.In a preferred embodiment, the longitudinal extent of the spring strip can be a multiple of the longitudinal extent of the grooved strip, with several grooved strips preferably being provided along the longitudinal extent of the spring strip and with preferably at least one web strip being provided, which can be latched with the latching recess of the spring strip. Several components can then also be provided on the several slot strips. For example, a load-bearing beam could be attached to the attachment area of the single spring strip, with several slats being arranged on the attachment areas of the multiple slot strips, which are to be aligned perpendicularly to the load-bearing beam and are to be attached to the load-bearing beam. In this way, for example, roof battens could be arranged, aligned and fixed on the rafters of a roof truss without the use of tools.
Bei einer alternativen Ausführungsform kann die Längserstreckung der Nutleiste ein Vielfaches der Längserstreckung der Federleiste betragen, wobei vorzugsweise entlang der Längserstreckung der Nutleiste mehrere Federleisten vorgesehen sind und wobei vorzugsweise zumindest eine Stegleiste vorgesehen ist, welche mit den Rastausnehmungen der Federleisten verrastbar ist. Eine ähnliche Konstruktion wie im Beispiel zuvor ist nun leicht realisierbar, wobei der tragende Balken nun lediglich mit der einzigen Nutleiste bestückt sein kann und wobei die Latten mit den mehreren Federleisten verbunden sein können.In an alternative embodiment, the longitudinal extent of the grooved strip can be a multiple of the longitudinal extent of the spring strip, with several spring strips preferably being provided along the longitudinal extent of the grooved strip and with at least one web strip preferably being provided, which can be latched with the latching recesses of the spring strips. A similar construction as in the example above can now be easily implemented, in which case the load-bearing beam can now only be fitted with the single grooved strip and the slats can be connected to the multiple tongue strips.
Bei einer möglichen Variante der Erfindung ist von der Rastverbindungsanordnung zumindest ein Bauteil umfasst. Dieses Bauteil und die Feder und/oder dieses Bauteil und die Nut sind bei dieser Variante bevorzugt einstückig ausgebildet, so dass der Befestigungsbereich zwischen Feder bzw. Nut und Bauteil mittels des Umfangsabschnittes des Bauteils realisiert ist. Diese Variante empfiehlt sich für anwendungsspezifische Konstruktionen, welche integrale Bauteile erfordern, die beispielsweise im Extrusionverfahren hergestellt sein können.In one possible variant of the invention, at least one component is included in the latching connection arrangement. In this variant, this component and the tongue and/or this component and the groove are preferably formed in one piece, so that the fastening area between the tongue or groove and the component is realized by means of the peripheral section of the component. This variant is recommended for application-specific designs that require integral components that can be manufactured, for example, using an extrusion process.
Generell sei erwähnt, dass unter dem weiter oben erläuterten vielfach höheren Kraftaufwand beim Lösen der Verbindung ein eindeutig messbarer Kraftunterschied verstanden wird, welcher über die üblichen Toleranzgrenzen der verwendeten Materialien und Messmittel hinausgeht. Die Dimensionierung und Konzipierung der erfindungsgemäßen Rastanordnung erfolgt derart, dass der Unterschied der erforderlichen Kräfte beim manuellen Herstellen und Lösen der Verbindung bezüglich seiner Intensität haptisch für einen Werker eindeutig wahrnehmbar ist. Vorzugsweise wird darunter auch verstanden, dass das Lösen der Verbindung mindestens den doppelten Kraftaufwand erfordert, verglichen mit dem Herstellen der Verbindung. Idealerweise erfolgt die Dimensionierung der Rastelemente so, dass das Herstellen der Verbindung mit einem deutlich hörbaren "Schnappgeräusch" verbunden ist, während das Lösen der Verbindung weniger geräuschintensiv erfolgt. Zusätzlich kann das Aufsitzen und/oder Einrasten der Stegleiste auf der Nutleiste als akustische Signalisierung für eine gesicherte Verbindung dienen.In general, it should be mentioned that the often higher expenditure of force explained above when loosening the connection is understood to mean a clearly measurable difference in force, which exceeds the usual tolerance limits of the used materials and measuring equipment. The dimensioning and design of the latching arrangement according to the invention is carried out in such a way that the difference in the forces required when manually making and loosening the connection with regard to its intensity can be clearly felt by a worker. This is preferably also understood to mean that releasing the connection requires at least twice the amount of force compared to establishing the connection. Ideally, the locking elements are dimensioned in such a way that the connection is made with a clearly audible "snapping noise", while the connection is released with less noise. In addition, the seating and/or snapping of the web strip on the groove strip can serve as an acoustic signal for a secure connection.
Ein erfindungsgemäßes Bauteil umfasst mindestens eine Nutleiste wie zuvor beschrieben und/oder mindestens eine Federleiste wie zuvor beschrieben. Idealerweise ist das Bauteil einstückig und vorzugsweise mittels eines Extrusionsverfahrens bei Verwendung eines geeigneten Extrusionswerkzeuges herstellbar. Der Befestigungsbereich der Nutleiste und/oder Federleiste wird in diesem Falle mittels eines Umfangsabschnittes des Bauteiles (z.B. Bauteilkonturabschnitt) realisiert, entlang dessen die Nut und/oder Feder außerhalb der Bauteilkonturen angeordnet ist. Hierzu sind an einem bevorzugt verwendeten Extrusionswerkzeug Ausnehmungen vorgesehen, deren Konturen korrespondierend zum Nutquerschnitt und/oder korrespondierend zum Federquerschnitt ausgebildet sind. Ein solches Bauteil hat den Vorteil, dass es mit einem zweiten, vorzugsweise im Wesentlichen identischen, Bauteil, welches ebenfalls eine solche Nutleiste und/oder Federleiste umfasst, werkzeuglos verbunden werden kann. Beide Bauteile können anschließend relativ zueinander in Längsrichtung ausgerichtet werden und nach der Ausrichtung vorzugsweise zusätzlich mittels der Stegleiste fixiert werden, so dass der ebenfalls beanspruchte Baukörper bei hoher Stabilität realisierbar ist.A component according to the invention comprises at least one groove strip as described above and/or at least one spring strip as described above. Ideally, the component is in one piece and can preferably be produced by means of an extrusion process using a suitable extrusion tool. In this case, the fastening area of the tongue and groove strip is realized by means of a peripheral section of the component (e.g. component contour section), along which the groove and/or tongue is arranged outside the component contours. For this purpose, recesses are provided on a preferably used extrusion tool, the contours of which are designed to correspond to the groove cross section and/or to correspond to the tongue cross section. Such a component has the advantage that it can be connected without tools to a second, preferably substantially identical component, which also includes such a tongue and groove strip. Both components can then be aligned relative to each other in the longitudinal direction and, after the alignment, preferably additionally fixed by means of the web bar, so that the structure that is also claimed can be realized with high stability.
Weiter umfasst die Erfindung ein Montageverfahren wie beansprucht, dessen Vorteile sich aus den bisherigen Erläuterungen ergeben.The invention also includes an assembly method as claimed, the advantages of which result from the previous explanations.
Es versteht sich, dass die vorstehend genannten Merkmale und die nachfolgend noch zu erläuternden Merkmale in den Zeichnungen nicht nur in der jeweils angegebenen Merkmalskombination, sondern auch in anderen, hier nicht explizit genannten Merkmalskombinationen oder in Alleinstellung oder isoliert auftreten können, ohne den Rahmen der vorliegenden Erfindung zu verlassen.

Der im Rahmen dieser Beschreibung verwendete Begriff Fügerichtung A bezieht sich auf eine erste Richtung, gemäß derer die Feder 201 der Federleiste 200 in die Nut 301 der Nutleiste 300 einzubringen ist, um die erfindungsgemäße Verrastung herbeizuführen. Der im Rahmen der Beschreibung verwendete Begriff Querrichtung B beschreibt eine zweite Richtung, welche quer, also im Wesentlichen senkrecht, zur Fügerichtung A ausgerichtet ist. Die Fügerichtung A und die Querrichtung B spannen eine erste Ebene auf, welche den Blattebenen der Abbildungen entspricht, in denen Schnitte von erfindungsgemäßen Anordnungen gezeigt sind. Die gezeigten Schnitte der Leisten 100, 200, 300 liegen jeweils in diesen Blattebenen. Der Begriff Längsrichtung C bezieht sich auf eine dritte Richtung, welche quer, also im Wesentlichen senkrecht bzw. 90 Grad, zur Fügerichtung A und gleichzeitig auch quer, also im Wesentlichen senkrecht bzw. 90 Grad, zur Querrichtung B ausgerichtet ist. Die Fügerichtung A und die Längsrichtung C spannen eine zweite Ebene auf, welche senkrecht zu den Blattebenen der Abbildungen angeordnet ist, in denen Schnitte von erfindungsgemäßen Anordnungen gezeigt sind. Diese Ebene wird auch als Fügeebene bezeichnet.The term joining direction A used in this description refers to a first direction in which the
Der im Rahmen der Beschreibung verwendete Begriff Längserstreckung beschreibt eine an den Leisten 100, 200, 300 tatsächlich messbare Längenausdehnung in Längsrichtung C (Länge), und der im Rahmen der Beschreibung verwendete Begriff Quererstreckung beschreibt eine an den Leisten 100, 200, 300 tatsächlich messbare Längenausdehnung in Querrichtung B (Breite). Sofern die Ausdehnung der Leisten 100, 200, 300 in Längsrichtung C und die Ausdehnung der Leisten 100, 200, 300 in Querrichtung B in etwa identisch sind, liegt eine punktuelle Anordnung vor. In diesem Falle kann die Länge bzw. die Breite dann einem Leistendurchmesser entsprechen.The term longitudinal extent used in the context of the description describes an actually measurable linear expansion in the longitudinal direction C (length) on the
Sämtliche nachfolgenden Zeichnungen zeigen die Erfindung sowie deren Varianten und Anwendungen lediglich grob schematisch. Die gezeigte Auswahl von Ausführungsformen ist nicht abschließend und lediglich als beispielhaft zu betrachten.All of the following drawings show the invention and its variants and applications only roughly schematically. The selection of embodiments shown is not final and should only be regarded as exemplary.
An der linken und/oder an der rechten Längsseite des Steges 102 kann jeweils eine Hinterschneidung 105 vorgesehen sein, welche beispielsweise mittels einer sich entlang der Längsseiten erstreckenden Nut 105 realisiert sein kann. In Fügerichtung A ist an der Stegunterseite 106 eine Materialverjüngung vorgesehen. Im Beispiel ist dies mittels eines spitz zulaufenden Endabschnittes realisiert. Dies dient dazu, das Einführen des Steges 102 in die Öffnung der Rastausnehmung 205 der Feder 201 zu erleichtern, denn die Öffnungsbreite der Rastausnehmung 205 entspricht im Wesentlichen der maximalen Querschnittsbreite des Steges 102 oder ist vorzugsweise mit einer im Vergleich zur maximalen Querschnittsbreite des Steges 102 leicht reduzierten Breite realisiert, so dass die beidseitigen Schenkel der Rastausnehmung 205 beim Einführen des Steges 102 eine Spreizung erfahren. Die Hinterschneidung 105 kann auch dazu dienen, den Kraftaufwand beim Herausnehmen des Steges 102 aus der Rastausnehmung 205 der Feder 201 ggf. im Zusammenwirken mit vorzugsweise innerhalb der Rastausnehmung 205 vorgesehenen zusätzlichen Rastelementen zu beeinflussen. Primär dient die Hinterschneidung 105 am Steg 102 jedoch zur Verrastung mit durch die Hinterschneidung 207 an der Rastausnehmung 205 bedingten Vorsprüngen im Bereich des Eingangs der Rastausnehmung 205.An undercut 105 can be provided on the left-hand and/or right-hand longitudinal side of the
An der Oberfläche eines ggf. vorhandenen Stegaufsatzes 101 kann ein Verbindungsmittel 104, beispielsweise zur lösbaren Anordnung eines elektrischen Verbrauchers (nicht gezeigt) am Stegaufsatz 101, vorgesehen sein. Beispielsweise kommt ein doppelseitiges Klebeband 104, ein Klettverschluss 104, oder dergleichen in Frage. Alternativ kann auch eine Montageplatte 104 als Verbindungsmittel 104 vorgesehen sein, mittels welcher elektrische und/oder nicht elektrische Gegenstände mechanisch am Stegaufsatz 101 fest oder lösbar anordenbar sein können. Vorzugsweise ist von der Stegleiste 100 ein Mittel 103 zu Verteilung von Energie und/oder von Signalen umfasst, vorzugsweise ein elektrischer Leiter 103 und/oder ein LWL (z.B. Glasfaserleitung) 103. Zusatzfunktionen können ebenfalls von der Stegleiste 100 erfüllt werden, wie beispielsweise eine Abdichtung zwischen den Bauteilen 203, 303 und/oder die Bereitstellung einer Beleuchtung (z.B. LED-Leiste). Im Rahmen unterschiedlichster spezifischer Anwendungen kann die Stegleiste 100 Zusatzfunktionen übernehmen, beispielsweise die Funktion einer Sockelleiste bei Fußbodenkonstruktionen.A connecting
Die Stegleiste 100 kann als Strang mittels Extrusion hergestellt werden, wobei vorzugsweise das Mittel 103 während der Extrusion kontinuierlich vom Kunststoffmaterial umschlossen wird, bis die gewünschte Längenausdehnung der Stegleiste 100 hergestellt ist. Die Stegleiste 100 kann anschließend vom Strang abgetrennt werden. Auch das Verbindungsmittel 104 könnte bereits im Rahmen dieses Herstellprozesses am Kunststoffmaterial angeordnet werden. Dabei werden der Leistenkunststoff und/oder das Mittel 103 und/oder das Verbindungsmittel 104 bevorzugt in einem einzigen Arbeitsgang durchtrennt.The
Die Federleiste 200 kann mittels der Anlagefläche 202 an dem Umfangsabschnitt des Bauteiles 203 derart angeordnet sein, dass die Feder 201 außerhalb der Bauteilkontur oder unmittelbar angrenzend an die Bauteilkontur verläuft. Eine zweite, vorzugsweise in ihrer Breite gegenüber der ersten Anlagefläche 202 reduzierte, Anlagefläche 202 kann, wie im Bild lediglich beispielhaft gezeigt, am rechten Federschenkel vorgesehen sein.The
Vorzugsweise sind die linksseitig und die rechtsseitig entlang der Feder 201 verlaufenden Anlageflächen 202 im Wesentlichen eben ausgebildet und liegen in einer gemeinsamen Ebene, versetzte und sich schneidende Ebenen wären ebenfalls denkbar. Die beiden Anlageflächen 202 mit ihren bevorzugt unterschiedlichen Abmessungen könnten selbstverständlich alternativ auch vertauscht an der Feder 201 angeordnet sein.Preferably, the contact surfaces 202 running along the
Das Bauteil 203 kann mittels eines Verbindungsmittels 206 (z.B. Klebeband, Klettband, Kleberaupe und dergleichen) an der Anlagefläche 202 fest angeordnet sein. Im Bereich der Verbindung zwischen Feder 201 und Anlageflächen 202 umfasst die Kontur des Federquerschnittes beidseitig Einkerbungen 204, welche sich in Längsrichtung C erstrecken und vorgesehen sind, um mit korrespondierenden Vorsprüngen 304 an der Nut 301 der anschließend im Rahmen der
Die gezeigte Feder 201 umfasst eine Rastausnehmung 205, welche zur Aufnahme des aus der
Die Nutleiste 300 kann mittels der Anlagefläche 302 an dem Bauteilumfangsabschnitt bzw. dem Bauteilkonturabschnitt derart angeordnet sein, dass die Nut 301 entlang einer der beiden Außenseiten bzw. entlang des Bauteilrandes und außerhalb der Bauteilkontur oder unmittelbar angrenzend an die Bauteilkontur verläuft. Eine zweite, in ihrer Breite gegenüber der ersten Anlagefläche 302 reduzierte, Anlagefläche 302 kann, wie im Bild lediglich beispielhaft gezeigt, am linken Nutschenkel vorgesehen sein. Vorzugsweise liegen die linksseitig und die rechtsseitig entlang der Nut 301 verlaufenden Anlageflächen 302 auf unterschiedlichen Ebenen. Während die im Bild rechts gezeigte erste Anlagefläche 302 der Anordnung des Bauteils 303 dient, dient die im Bild links gezeigte zweite und gegenüber der ersten Anlagefläche 302 höhenmäßig versetzte zweite Anlagefläche 302 als Auflage für die Unterseite der bauteilaufnehmenden Anlagefläche 202 der Federleiste 200, sobald die Feder 201 mit der Nut 301 verrastet ist. Vorzugsweise ist daher diese zweite Anlagefläche 302 der Nutleiste 300 derart an der Nutleiste 300 angeordnet, dass nach Herstellung einer Rastverbindung zumindest die bauteilaufnehmende Anlagefläche 202 der Federleiste 200 und die bauteilaufnehmende Anlagefläche 302 der Nutleiste 300 im Wesentlichen auf einer gemeinsame Ebene liegen, so dass die Unterseite der bauteilaufnehmenden Anlagefläche 202 der Federleiste 200 an der Oberseite der zweiten Anlagefläche 302 der Nutleiste 300 aufliegt. Das Bauteil 303 kann mittels eines Verbindungsmittels 305 (z.B. Klebeband, Klettband, Kleberaupe und dergleichen) auf einer der beiden Anlageflächen 302 fest angeordnet sein.The
Am Nuteingang sind beidseitig Vorsprünge 304 vorgesehen, welche mit den aus
Die gezeigte Rastverbindungsanordnung umfasst jeweils die einstückige Kunststoff-Nutleiste 300 mit einer entlang der Nut 301 verlaufenden ersten ebenen Anlagefläche 302 für ein erstes Bauteil 303 (rechts im Bild). Vorzugsweise ist entlang der Nut 301 bereits ein erstes Bauteil 303 auf der Anlagefläche 302 angeordnet. Weiter ist umfasst eine einstückige Kunststoff-Federleiste 200 mit einer entlang der Feder 201 verlaufenden zweiten ebenen Anlagefläche 202 für ein zweites Bauteil 203 (links im Bild). Vorzugsweise ist entlang der Feder 201 bereits ein zweites Bauteil 203 auf der Anlagefläche 202 angeordnet. Nutleiste 300 und Federleiste 200 erstrecken sich jeweils in bzw. parallel zur Längsrichtung C.The snap-in connection arrangement shown comprises the one-piece
Die Querschnitte von Feder 201 und Nut 301 sind zueinander korrespondierend mittels der Rastelemente 204, 304 (siehe auch
Der Steg 102 ist derart konstruiert, dass er vorzugsweise im Bereich der Öffnung der Rastausnehmung 205 formschlüssig in diese einführbar ist, während der Stegaufsatz 101 vorzugsweise außerhalb der Rastausnehmung 205 an einer Anlagefläche 202 der Federleiste 200 anliegt. Der Steg 102 kann somit den Eingang der Rastausnehmung 205 zumindest abschnittsweise verschließen. Der Steg 102 ist derart dimensioniert, dass er nach der Verrastung mit der Rastausnehmung 205 versteifend auf den annähernd ringsegmentförmig ausgebildeten Federquerschnitt 201 wirkt und somit die Schenkel der Rastausnehmung 205 gegeneinander abstützt und vorzugsweise leicht spreizt. Dies hat zur Folge, dass die Feder 201 innerhalb der Nut 301 mittels Klemmwirkung fixiert wird. Diese Klemmwirkung erschwert ein manuelles Entfernen der Feder 201 aus der Nut 301 und hemmt abhängig von den auftretenden Reibungskräften im Wesentlichen ein relatives Verschieben zwischen Nutleiste 300 und Federleiste 200.The
Für die Längserstreckung der Leisten 100, 200, 300 gilt bevorzugt:
Letztlich jedoch hängt dieses Verhältnis vom konkreten Anwendungsfall ab und ist im Rahmen beispielsweise eines Extrusionsverfahrens zur Herstellung der Leisten 100, 200, 300 frei und ggf. auch vollautomatisiert und bevorzugt anwendungsspezifisch konfigurierbar bzw. steuerbar.Ultimately, however, this ratio depends on the specific application and can be configured or controlled freely and possibly also fully automatically and preferably application-specifically within the scope of, for example, an extrusion process for producing the

Die Querschnitte von Feder 201 und Nut 301 sind zueinander korrespondierend mittels Rastelementen 304, 204 erfindungsgemäß so ausgebildet, dass bspw. zwischen einer Feder 201 eines ersten Bauteils 203 und einer Nut 301 eines zweiten Bauteils 303 eine Rastverbindung herstellbar ist. Das Verbindungskonzept ist derart konzipiert, dass ein relatives manuelles Verschieben beider Bauteilen 203, 303 auch noch nach der Herstellung der Rastverbindung zwischen Nut 301 und Feder 201 möglich ist. Die Bauteile 203, 303 bleiben somit noch in Längsrichtung der Leisten 200, 300 justierbar. Eine von der Längsrichtung abweichende Bewegung wird jedoch erschwert. Die in
