Definitions

  • the present invention relates to a latching connection arrangement for connecting components as well as a component, a structural body and an assembly method.
  • the application area 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 protection elements and the like.
  • This can also be a combination of a surface element with other commercially available components, such as, for example, profile elements, strip elements, frame elements, rod elements and the like.
  • So-called tongue and groove connections are known, for example, for producing connections between surface elements, as shown in document EP 021 4643 A2.
  • tongue-and-groove connections have the disadvantage that the connection can possibly be released very easily, for example during assembly and alignment when a force acts on the components against the joining direction.
  • the document DE 29924454 U1 shows a solution in which floor panels are locked along their front edges in the vertical direction via one or more frontal projections of a panel by locking them into corresponding recesses in the other panel.
  • the solution known from DE 38 06091 A1 relates to a structural body composed of two or more profile strips, a tongue-and-groove connection being established between two adjacent profile strips.
  • One strip is provided with a longitudinally extending groove
  • the other strip is provided with a longitudinally extending web which engages in the groove. It is desirable to have alternative and flexible solutions available that can be used universally.
  • the assembly as well as the alignment of the components should be carried out easily with the greatest possible precision during assembly.
  • a locking 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.
  • a component is understood to be any body that can be connected to at least one other body of the same or different structure, each of the bodies having at least one front side and one rear side as well as several front sides on which a bar can be arranged.
  • the latching connection arrangement comprises a groove strip (i.e. a first strip with a groove) with a first fastening area, preferably immediately next to and parallel to the groove, that is to say along the groove.
  • the groove is used to accommodate the tongue of a spring strip, which is explained below.
  • the fastening area is used to arrange the groove strip along a circumferential section of a component, so that the groove ideally runs along the component edge and is easily accessible next to the component surface.
  • the component can be a cuboid component, preferably a surface element such as a pane, a panel, a cladding, a plate, a lath and / or a bar, a roof, wall and floor element, a solar panel or the like.
  • the groove strip extends in a first longitudinal direction, preferably transversely, preferably perpendicularly, to the groove strip cross section, and also in a first transverse direction.
  • the longitudinal extension can roughly correspond to the transverse extension, and possibly also be smaller.
  • the The longitudinal extent or the transverse extent also correspond to a circle diameter. This applies in particular when the groove 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 spring strip described below is guaranteed as claimed.
  • the latching connection arrangement additionally comprises a spring strip (i.e. a second strip with a spring) with a second fastening area, preferably immediately next to and parallel to the spring, that is to say along the spring.
  • the tongue is intended to be inserted into the groove of the groove strip described above.
  • the fastening area is used to arrange the spring strip along a peripheral section of a component, so that the spring ideally runs along the component edge and is easily accessible next to the component surface.
  • 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 extension of the spring strip can also be many times greater than the transverse extension, so that the typical strip character is created.
  • the length of the spring strip can roughly correspond to the width of the spring strip cross-section or it can also be smaller.
  • the longitudinal extent or the transverse extent can also correspond to a circular diameter. This applies in particular when the spring slat 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 above-described groove strip is guaranteed as claimed.
  • connection changes proportionally to the longitudinal extension and thus, depending on the task, either a large number of punctual connections and / or non-punctual connections or a combination of punctual and non-punctual connections may be required for the requirement of 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 perpendicular in relation to the longitudinal directions, so that a locking connection is established between the spring strip and the groove strip , preferably a positive locking connection, depending on the depth of immersion of the tongue in the groove, measured from the upper edge of the groove opening, can be produced.
  • a latching connection is also understood to mean that the tongue automatically engages in the groove by means of a snap action 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 designed and coordinated with one another in such a way that the tongue can be pushed into the groove in the joining direction during assembly and inevitably latches with the groove strip when the end position is reached.
  • the latching elements are preferably also designed and coordinated with one another in such a way that after reaching the immersion depth, a movement against the joining direction is hardly possible any more or the groove strip and spring strip are fixed transversely to their longitudinal directions.
  • the latching elements can preferably also be formed like a barb.
  • the locking connection arrangement allows a relative movement of the spring strip with respect to the groove strip or a relative movement of the groove strip with respect to the spring strip along one of the two longitudinal directions of the Last to. Loosening the connection requires a much greater effort 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 former case of the common plane, both fastening areas form a common fastening plane, which is formed horizontally with respect 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 other than 90 degrees with respect to the joining plane.
  • the minimum dimension of the slot bar and / or the spring bar depends in particular on the desired release forces which a latching connection arrangement according to the invention is to withstand, as well as on the production method and the tolerance thresholds that are usually prevalent. Both miniature applications with low stability requirements, for example in model construction, and applications with very high requirements for stability, for example in building construction or civil engineering, are conceivable.
  • the slot strip and / or the spring strip is advantageously made from a plastic (e.g. PA 6 or PA 6.6) by extrusion of this plastic in the context of an extrusion process as an endless strand, which can be cut to length in sections in order to obtain the desired longitudinal extension.
  • a plastic e.g. 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 groove strip and the spring strip.
  • both profile strips latch in a stable manner in the joining direction, so that manual loosening is still possible, but preferably only with a significantly measurable higher expenditure of force than when joining.
  • This enables 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 established.
  • the haptics achieved according to the invention when establishing / releasing the locking connection arrangement can prevent accidental manual release of the connection and also premature release in the event of intentional or unintentional loading of the connection.
  • the slot bar and spring bar can be arranged on any component which, at least at its edge area, provides a fastening surface that corresponds to the fastening area.
  • the latching connection arrangement according to the invention is suitable for components with a front or top or rear or rear side correspondingly configured at least in one edge area.
  • windshields and / or other vehicle windows as well as sunroofs could first be locked to the body and only then aligned without the connection that has already been made being inadvertently released.
  • aligning the longitudinal direction of the strips can also serve as a reference line.
  • Gap size specifications are also possible depending on the dimensions of the components according to the invention (eg 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 pre-fixes the components in the desired position in a self-retaining manner.
  • 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 the arrangement of component surfaces that are not flat, such as components with round contours.
  • appropriately designed adapter elements could be provided, the contours of which correspond on the one hand to the contours of the fastening areas and on the other hand also to the contours of the components.
  • a fastening means for fastening a component for example a Velcro tape, adhesive tape or the like, can be provided on the fastening areas.
  • the fastening areas are particularly preferably designed as, preferably flat, contact surfaces in order to offer a contact 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 latching connection arrangement makes it possible to realize surfaces and cladding for building structures and structures from a large number of surface elements.
  • a latching recess extends along and within the spring, which is prepared for latching with the web of a web strip (ie with a third strip comprising a web) and in the joining direction from the Is accessible when viewed from above.
  • 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 the context of this description relates to a first direction according to which the tongue of the spring strip is to be introduced into the groove of the groove strip in order to bring about the latching according to the invention.
  • the latching recess When inserting the web into the latching recess of the spring, the latching recess can then be filled at least in sections with the material of the web in order to inhibit the flexibility of both legs at least in one direction of movement.
  • the web that can be clamped between the spring legs can support both spring legs against one another and act like a cross strut 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 with a web and preferably with a web attachment is included.
  • the web attachment can be connected to the web, the cross-sectional contours of the web and the locking recess of the spring being designed to correspond to one another using locking elements, so that the web can be locked to the locking recess at least in sections in a form-fitting manner.
  • the web attachment 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, as explained above, which secures the latching between tongue and groove against manual and / or accidental loosening.
  • the arrangement is designed in such a way that a non-destructive release of the latching between the groove and the tongue is only possible after the web strip has been removed beforehand. It is preferably provided that for releasing the web from the latching recess of the spring a force is required which is many times higher than the force required to insert the web into the spring.
  • the invention provides an advantageous solution which combines the advantages of essentially non-releasable connections and releasable connections in the context of an assembly and / or disassembly of components.
  • the web attachment advantageously also functions as a cover for the latching recess of the spring and / or a gap that may possibly exist between the two components after the latching connection has been established.
  • the web attachment that protrudes from the locking recess can also take on additional functions and preferably comprise 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 the transmission of signals.
  • an electrical component e.g. LED strip, sensors such as rain sensors, etc.
  • the web can also be electrified and comprise a conductor.
  • the web attachment can advantageously also be implemented as a gap seal in order to meet the requirements of the IP protection classes, for example. So could if necessary, splash water protection according to IP classification (e.g. IP 65) can be implemented between the two components.
  • IP classification e.g. IP 65
  • the web strip described above is very particularly preferable for the web strip described above to be pivotably connected, at least in sections, to the spring strip or to the groove strip, preferably at the transition between the tongue or groove and the fastening area.
  • This connection can preferably be realized in one piece in the context of a (co) extrusion process, for example, at the same time with the folding position 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 strip can be lost during assembly work.
  • This variant of the invention is also advantageous when working on inclines or at vertical installation locations.
  • the force required to release the latch between the latching recess and the web is many times higher than the force required to produce the latch. This increases the security of the connection, since it can be assumed that inadvertent loosening of the connection due to external influences usually occurring 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 groove strip, with a plurality of groove strips preferably being provided along the longitudinal extent of the spring strip and preferably at least one web strip being provided which can be locked with the locking recess of the spring strip.
  • Several components can then also be provided on the several groove strips.
  • a load-bearing beam could be attached to the fastening area of the single spring strip, with several slats on the fastening areas of the multiple groove strips are arranged, which are to be aligned perpendicular to the supporting beam and to be attached to the supporting beam.
  • roof battens could be arranged, aligned and fixed without tools on the rafters of a roof truss.
  • the longitudinal extent of the slot bar can be a multiple of the longitudinal extent of the spring bar, with several spring bars preferably being provided along the longitudinal extent of the slot bar and preferably at least one web bar being provided which can be locked with the locking recesses of the spring bars.
  • the latching connection arrangement comprises at least one component.
  • This component and the tongue and / or this component and the groove are preferably formed in one piece in this variant, so that the fastening area between the tongue or groove and component is implemented by means of the peripheral section of the component.
  • This variant is recommended for application-specific constructions that require integral components that can be manufactured using the extrusion process, for example.
  • the much higher expenditure of force when loosening the connection is understood to mean a clearly measurable difference in force which goes beyond the usual tolerance limits of the materials and measuring equipment used.
  • the locking arrangement according to the invention is dimensioned and designed in such a way that the difference in the forces required during manual production and release of the connection with regard to its intensity can be clearly perceived haptically by a worker.
  • This is preferably also understood to mean that the loosening of the connection requires at least twice the expenditure of force compared to the establishment of the connection.
  • the locking elements are dimensioned in such a way that the establishment of the connection is associated with a clearly audible "snap noise" while the loosening of the connection is less noisy.
  • the seating and / or latching of the web strip on the groove strip can serve as acoustic signaling for a secure connection.
  • a component according to the invention comprises at least one slot strip as described above and / or at least one spring strip as described above.
  • the component is one-piece and can preferably be produced by means of an extrusion process using a suitable extrusion tool.
  • the fastening area of the slot bar and / or spring bar is implemented in this case 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 an extrusion tool that is preferably used, 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 essentially identical, component which also includes such a slot strip and / or spring strip. Both components can then be aligned relative to one another in the longitudinal direction and, after the alignment, preferably also be fixed by means of the web strip, so that the building structure, which is also stressed, can be realized with high stability.

Abstract

L'invention concerne entre autres un ensemble de raccordement par encliquetage comportant un liteau rainuré (300) et un liteau élastique (200). Il est souhaitable de disposer d'une solution la plus flexible possible pour réaliser un assemblage détachable, qui peut s'utiliser de manière universelle et permet d'assembler les unes aux autres autant de pièces (203, 303) que possible qui peuvent être sélectionnées librement. L'invention vise en outre à ce que le montage et l'alignement de ces pièces (203, 303) soient aisés à effectuer. A cet effet, selon l'invention, les sections transversales du ressort (201) et de la rainure (301) sont conçues de sorte à être en correspondance mutuelle, par utilisation d'éléments d'encliquetage, de manière qu'un assemblage par encliquetage peut être réalisé entre le ressort (201) et la rainure (301), ledit assemblage par encliquetage permettant un mouvement relatif du liteau élastique (200) par rapport au liteau rainuré (300) ou un mouvement relatif du liteau rainuré (300) par rapport au liteau élastique (200). Un mouvement intervenant transversalement à une des deux directions longitudinales est néanmoins entravé. De plus, un évidement d'encliquetage (205) destiné à s'encliqueter avec l'élément de liaison (102) d'une entretoise (100) faisant office de mécanisme de sécurité s'étend le long et à l'intérieur du ressort (201). L'invention fournit ainsi une solution flexible permettant d'assembler les pièces (203, 303) les unes aux autres, de préférence de manière sécurisée.
