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.

  • 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.

  • This second contact surface 302 of the grooved strip 300 is therefore preferably arranged on the grooved strip 300 in such a way that after a snap-in connection has been established, at least the component-receiving contact surface 202 of the spring strip 200 and the component-receiving contact surface 302 of the grooved strip 300 lie essentially on a common plane, so that the underside the component-receiving contact surface 202 of the spring strip 200 rests on the upper side of the second contact surface 302 of the grooved strip 300.

  • tongue 201 and groove 301 correspond to one another by means of locking elements 204, 304 (see also figure 2 and 3 ) formed so that between tongue 201 and groove 301 a releasable locking connection can be produced. It can be clearly seen how the projections 304 on the groove 301 engage in the indentations 204 on the tongue 201 .
  • the latching elements 204, 304 simultaneously assume the function of a guide, so that the spring strip 200 relative to the grooved strip 300 or the grooved strip 300 relative to the spring strip 200 remains variable and movable along its longitudinal extension even after latching.
  • the arrangement is constructed overall in such a way that the contact surfaces 302, 202 of the tongue and groove strip 300 and the tongue strip 200 intended for receiving a component 203, 303 lie on a common plane or alternatively lie on two different, mutually parallel or intersecting planes.

  • 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.
