Description

Die Erfindung betrifft mit starren Kupplungselementen vernetzte Unterfederungselemente zur Verwendung in oder unter Matratzen oder Polstern von Sitz- oder Liegemöbeln, mit unteren und/ oder oberen Auflagerflächen und mit Aufnahmen für starre Kupplungselemente mit mindestens einem Querbalken und einem Längsbalken und mit gegenseitigen Rastmitteln in den Aufnahmen und im Bereich der Enden der Querbalken.The invention relates to crosslinked with rigid coupling elements Unterfederungselemente for use in or under mattresses or upholstery of sitting or lying furniture, with lower and / or upper bearing surfaces and receptacles for rigid coupling elements with at least one crossbar and a longitudinal beam and with mutual locking means in the receptacles and in the area of the ends of the transom.

Eine bekannte Federungsvorrichtung, EP 1 602 303 B1 , umfasst mehrere elastisch verformbare Federelemente mit oberen und unteren Auflagerflächen, die zur Herstellung einer Vernetzung in einer Mittelebene der Unterfederungselemente durch starre Verbindungsmittel miteinander verbunden sind, wobei diese in Draufsicht abwechselnd und in Staffelform angeordnet sind.A known suspension device, EP 1 602 303 B1 comprises a plurality of elastically deformable spring elements with upper and lower bearing surfaces, which are interconnected by means of rigid connecting means for establishing a cross-linking in a median plane of the lower suspension elements, wherein these are arranged alternately and in staggered form in plan view.

Nachteilig an dieser Art der Vernetzung von Unterfederungselementen ist die mangelnde Stabilität der Gesamtkonstruktion, da sich die einzelnen Federelemente stark seitlich verformen können, so dass sie zusätzlich einer starken seitlichen Abstützung durch weitere Stützelemente bedürfen. Auch die nur staffelförmige Möglichkeit einer Anordnung verhindert eine robuste und stabile Ausführung einer solchen durch vernetzte Unterfederungselemente gebildeten Unterfederung zur Verwendung in oder unter Matratzen oder Polstern von Sitz- oder Liegemöbeln.A disadvantage of this type of networking Unterfederungselementen is the lack of stability of the overall design, since the individual spring elements can strongly deform laterally, so that they also require strong side support by other support elements. Even the only graduated possibility of an arrangement prevents a robust and stable design of such formed by networked spring support under spring suspension for use in or under mattresses or upholstery of sitting or lying furniture.

Es ist weiterhin eine Federelementanordnung zur Hinterfederung von Matratzen oder Polsterelementen bekannt, EP 1 806 074 B1 , bei der eine Mehrzahl von benachbarten einteiligen Federelementen mittels Koppelelementen miteinander verbunden sind, die Rastmittel aufweisen, die in gegenüberliegende Rasten der Auflagerabschnitte benachbarter Federelemente einrasten.It is further known a spring element arrangement for the rear suspension of mattresses or upholstery elements, EP 1 806 074 B1 in which a plurality of adjacent one-piece spring elements are interconnected by means of coupling elements which have latching means which engage in opposite notches of the support sections of adjacent spring elements.

Bei dieser Art der Vernetzung wird eine Vielzahl von einzelnen Kupplungselementen benötigt und eine im ganzen wenig formstabile Unterfederung erzeugt, die ein Verdrehen einzelner Federelemente innerhalb der Vernetzung oder ein parallelogrammartiges Verschieben der gesamten Unterfederung ermöglicht. Zudem ist der Zusammenbau höchst arbeits- und zeitintensiv.In this type of networking, a plurality of individual coupling elements is required and generates a low-dimensionally stable bottom spring, which allows a twisting of individual spring elements within the network or a parallelogram-like displacement of the entire spring base. In addition, the assembly is extremely labor-intensive and time-consuming.

Aufgabe der Erfindung ist es, eine nenartige Vernetzung von Unterfederungselementen zur Verfügung zu stellen, die einfach und robust aufgebaut ist und die keine weiteren Stützelemente benötigt und die bei vermindertem Montageaufwand eine stabile Unterfederung verwirklicht.The object of the invention is to provide a nenartige networking of Unterfederungselementen available, which is simple and robust and which requires no further support elements and realized with reduced assembly costs a stable spring base.

Die Lösung dieser Aufgabe erfolgt in Verbindung mit den Oberbegriffsmerkmalen erfindungsgemäß durch die technischen Merkmale des kennzeichnenden Teils des ersten Schutzanspruches insbesondere dadurch, dass jedes Unterfederungselement in einer zu seiner Längsrichtung rechtwinkligen Querrichtung in den seitlichen Randbereichen ihrer Auflagerflächen beidseitig jeweils mindestens eine Aufnahme für jeweils ein Ende eines Querbalkens aufweist.The solution of this object is achieved in conjunction with the preamble features according to the invention by the technical features of the characterizing part of the first protection claim in particular in that each Unterfederungselement in a perpendicular to its longitudinal direction transverse direction in the lateral edge regions of their support surfaces on both sides in each case at least one receptacle for each one end Crossbar has.

Weitere vorteilhafte Ausgestaltungen des Gegenstandes der Erfindung ergeben sich mit und in Kombination aus den nachfolgenden Unteransprüchen.Further advantageous embodiments of the subject of the invention will become apparent with and in combination from the following subclaims.

Bei einer ersten Hauptausführungsform der Erfindung mit jeweils zwei Aufnahmen pro Seite wird erreicht, dass ein einzelnes Unterfederungselement nicht von einem einzelnen Kupplungselement in einer Mittelebene, sondern von insgesamt acht Kupplungselementen, von denen vier im Bereich der oberen Auflagerfläche und vier im Bereich der unteren Auflagerfläche, soweit vorhanden, vernetzt ist, wodurch eine extrem stabile Ausgestaltung einer solchen Unterfederung aus mehrfach gekoppelten Unterfederungselementen gewährleistet wird.In a first main embodiment of the invention with two receptacles per side is achieved that a single spring element Untersprungselement not of a single coupling element in a median plane, but of a total of eight coupling elements, four in the region of the upper support surface and four in the region of the lower support surface, if present, is networked, whereby an extremely stable design of such a suspension is ensured by multiple coupled Unterfederungselementen.

Gemäß einer besonders bevorzugten Ausgestaltung der Erfindung sind die Aufnahmen für die Enden der Querbalken von einer horizontalen Symmetrieachse, die quer zur Längsrichtung der Anordnung der Unterfederungselemente verläuft, gleichmäßig beabstandet, so dass auftretende Kräfte gleichmäßig auf die Unterfederungselemente und auf die Kupplungselemente übertragen werden.According to a particularly preferred embodiment of the invention, the receptacles for the ends of the transom from a horizontal axis of symmetry, which is transverse to the longitudinal direction of the arrangement of the lower suspension elements, evenly spaced, so that forces are transmitted evenly to the lower suspension elements and the coupling elements.

Diese Kupplungselemente weisen bevorzugt eine Doppel-T-Profil-förmige Grundform auf und die Aufnahmen sind rechtwinklig zur Längsrichtung und parallel zueinander ausgeführt, so dass die Enden der Querbalken sich durch einfaches seitliches Einschieben in diese Aufnahmen der Unterfederungselemente und eine gleichzeitiges, gegenseitiges Verrasten der Rastmittel montieren lassen. Diese Montageform ist selbsterläuternd und ermöglicht keine Fehlmontagen durch ausführendes Personal. Vorteilhaft an dieser Ausgestaltung ist ebenfalls, dass die Längsbalken in der Längsrichtung der Unterfederungselemente eng neben diesen entlang verlaufen, so dass der Spalt zwischen den in Längsrichtung angeordneten Unterfederungselementen zumindest in deren seitlichen Bereich von den Längsbalken der Kupplungselemente überbrückt wird und diese bei einer Belastung vertikale Kräfte aufnehmen und in die Unterfederungselemente einleiten können.These coupling elements preferably have a double-T-profile-shaped basic shape and the receptacles are perpendicular to the longitudinal direction and executed parallel to each other, so that the ends of the crossbars by simply sliding sideways in these recordings of the suspension elements and a simultaneous, mutual locking of the locking means let mount. This form of assembly is self-explanatory and does not allow incorrect assembly by executive personnel. Another advantage of this embodiment is that the longitudinal beams extend in the longitudinal direction of the lower suspension elements closely adjacent thereto, so that the gap between the longitudinally arranged Unterfederungselementen is bridged at least in the lateral region of the longitudinal beams of the coupling elements and these vertical forces under load record and can initiate the suspension elements.

Ein vollständig vernetztes Unterfederungselement einer solchen ersten Hauptausführungsform mit einer oberen und einer unteren Auflagerfläche wird so im gemeinsamen Verbund mehrerer vernetzter Unterfederungselemente vorteilhaft von acht Kupplungselementen gehalten und zwar zwei unteren rechts und links nach vorne gerichteten, zwei unteren rechts und links nach hinten gerichteten, zwei oberen rechts und links nach vorne gerichteten und zwei oberen rechts und links nach hinten gerichteten Kupplungselementen, so dass auch schrägt auf diese Unterfederung einwirkende Kräfte aufgenommen werden können, wozu natürlich auch die Form der Unterfederungselemente selber vorteilhaft beiträgt, die bevorzugt als liegend elliptisch-zylindrische Mantelkörper mit im Querschnitt konkav eingeformten Haupt- und Nebenscheiteln ausgeführt sein können, wobei die Mantelfläche mit einer Vielzahl von Flächenausnehmungen in ihren Mantelflächen versehen sein können. Ein solches Unterfederungselement ist in noch nicht vernetzbarer Form beispielsweise aus der DE 202009003041 U1 bekannt.A fully networked lower suspension element of such a first main embodiment with an upper and a lower support surface is held in the common composite of several networked Unterfederungselemente advantageous of eight coupling elements and two lower right and left facing forward, two lower right and left rearward, two upper right and left forward and two upper right and left rearward coupling elements, so that obliquely acting on this spring action forces can be absorbed, of course, the shape of the lower suspension elements itself contributes beneficial, preferably as lying elliptical cylindrical shell body with can be executed in cross-section concave shaped main and minor vertices, wherein the lateral surface can be provided with a plurality of Flächenausnehmungen in their lateral surfaces. Such a Unterfederungselement is in not yet cross-linkable form, for example, from DE 202009003041 U1 known.

Die Erfindung erlaubt jedoch die Verwendung vieler anderer bekannter Matratzenfedern, etwa mit nur einer oberen Auflagerfläche und einem vollkommen andersartig gestalteten Fußteil oder elastischen Elements des Unterfederungselementes.However, the invention allows the use of many other known mattress springs, such as with only one upper bearing surface and a completely different shaped foot or elastic element of the lower suspension element.

Die Aufnahmen für die Enden der Querbalken sind bevorzugterweise unmittelbar nebeneinander und kurz unterhalb der Auflagerflächen bzw. auf deren nach innen gerichteten Seiten angeordnet, so dass die Kupplungselemente zumindest im belasteten Zustand der Unterfederungselemente mittragende Auflagerflächen bilden können, sei es nur im Bereich der Längsbalken oder auch im nicht in den Aufnahmen eingesteckten Bereichen der Querbalken. Die enden der Querbalken können jedoch auch Rastmittel aufweisen, mit denen sie nicht seitlich in eine Aufnahme eines Unterfederungselementes eingesteckt werden können, sondern von oben oder unten oder von innen auf oder unter den Aufnahmen verrastbar sind.The receptacles for the ends of the crossbars are preferably arranged directly next to one another and just below the support surfaces or on their inwardly directed sides, so that the coupling elements can form supporting bearing surfaces at least in the loaded state of the under suspension elements, be it only in the area of the longitudinal beams or also in the areas of the transom not inserted in the receptacles. However, the ends of the crossbar may also have locking means with which they can not be inserted laterally into a receptacle of a lower suspension element, but can be latched from above or below or from the inside or on the recordings.

Bei einer weiteren Ausführungsform der vorliegenden Neuerung sind die linken nach hinten gerichteten, die rechten nach hinten gerichteten, die linken nach vorne gerichteten und die rechten nach vorne gerichteten oberen und unteren Kupplungselemente durch elastische Verbindungsstege miteinander verbunden, so dass diese Kupplungselemente selber senkrechte Belastungskräfte aufnehmen und abfedern können und gleichzeitig eine weitere gesteigerte Querstabilität der Unterfederung erzeugen.In a further embodiment of the present invention, the left rearward, the right rearward, the left forwardly directed and the right forwardly directed upper and lower coupling elements are interconnected by elastic connecting webs, so that these coupling elements themselves absorb vertical loading forces and can cushion and simultaneously produce a further increased lateral stability of the spring suspension.

Die zu vernetzenden Unterfederungselemente einer zweiten Hauptausführungsform des Gegenstandes der Erfindung sind hierzu zunächst in einer horizontalen Richtung hintereinander und in einer dazu horizontalen Querrichtung nebeneinander angeordnet und jedes Unterfederungselement ist in Querrichtung beidseitig mit einzelnen Rastenaufnahmen im Bereich seiner Auflagerfläche ausgestattet. Die neuerungsgemäßen, im wesentlichen kreuz- oder auch doppelkreuzförmigen Kupplungselemente sind mit Längs- und Querbalken versehen, die an ihren Enden mit Rastmitteln ausgestattet sind, von denen die Rastmittel der Querbalken in die Aufnahmen der Unterfederungselemente und die Rastmittel der Längsbalken mit ihren gegenseitig korrespondierenden Rastmitteln in die der benachbarten Kupplungselemente eingreifen.For this purpose, the sub-suspension elements to be cross-linked of a second main embodiment of the object of the invention are initially arranged in a horizontal direction one behind the other and side by side in a horizontal transverse direction and each lower suspension element is equipped on both sides with individual detent recesses in the region of its support surface in the transverse direction. The renewal, essentially cross or double cross-shaped coupling elements are provided with longitudinal and transverse beams, which are equipped at their ends with locking means, of which the locking means of the crossbars in the receptacles of the Unterfederungselemente and the locking means of the longitudinal beams with their mutually corresponding locking means in which engage the adjacent coupling elements.

Die erforderliche Anzahl von Kupplungselementen wird gegenüber dem zitierten Stand der Technik dadurch halbiert, ebenso wie der Montageaufwand. Des Weiteren wird nicht nur eine Verbindung benachbarter Federelemente erzeugt, sondern auch eine gegenseitige Verbindung der Kupplungselemente, wodurch in horizontaler Richtung eine sehr stabile Vernetzung der Unterfederungselemente erzielt wird. Vorteilhaft ist des weiteren, dass in der Längsrichtung die benachbarten Federelemente nicht unmittelbar miteinander vernetzt sind, so dass diese nahezu frei und ungehindert voneinander ein- und ausfedern können, wodurch sich der Komfort der damit unterstützen Sitz- oder Liegefläche oder Polster deutlich verbessert.The required number of coupling elements is halved compared to the cited prior art, as well as the installation effort. Furthermore, not only a connection of adjacent spring elements is generated, but also a mutual connection of the coupling elements, whereby in the horizontal direction a very stable networking of the lower suspension elements is achieved. It is also advantageous that in the longitudinal direction, the adjacent spring elements not directly are networked with each other, so that they can almost freely and unhindered from one another and spring, which significantly improves the comfort of the thus supported sitting or lying surface or upholstery.

Um der Unterfederung weitere Variationsmöglichkeiten hinzuzufügen, können im Bereich der Auflagerflächen von außen nach innen mehrere Rastenaufnahmen hintereinander vorgesehen sein, so dass die Unterfederungselemente in Querrichtung in unterschiedlichen Abständen zueinander angeordnet werden können. Eine solche Maßnahme ist recht einfach, aber sehr wirkungsvoll und ermöglicht auf einfachste Art und Weise auf die Unterfederungsqualität oder auf die Größe der Unterfederungsfläche Einfluss nehmen zu können.In order to add further variation possibilities to the lower suspension, a plurality of detent receptacles can be provided one behind the other in the region of the bearing surfaces from the outside in, so that the under-suspension elements can be arranged at different distances in the transverse direction. Such a measure is quite simple, but very effective and allows in the simplest way to influence the Unterfederungsqualität or on the size of the Unterfederungsfläche influence.

Vorteilhaft ist des Weiteren eine Ausführungsform der Erfindung, bei der die Unterfederungselemente auch in Längsrichtung in unterschiedlichen Abständen zueinander angeordnet werden können, wozu ein Kupplungselement an den Enden seiner Längsbalken vom Ende her mehrere, als Rastenaufnahmen ausgebildete Rastmittel aufweist und am gegenüberliegenden Ende jeweils eine Raste, so dass benachbarte Kupplungselemente in unterschiedlichen Abständen miteinander verrastet werden können.Also advantageous is an embodiment of the invention, in which the Unterfederungselemente can be arranged in the longitudinal direction at different distances from each other, including a coupling element at the ends of its longitudinal beams from the end more, designed as a detent recesses catch means and at the opposite end in each case a detent, so that adjacent coupling elements can be locked together at different distances.

Um die Vernetzung besonders praktikabel zu gestalten, sind die Längsbalken und die Querbalken mit Sollbruchstellen zum Abtrennen deren Enden ausgestattet, so dass beispielsweise die Balken im Randbereich einer Unterfederungsfläche nicht über die Kontur der Unterfederungselemente hervorstehen. Denkbar ist es auch, die Längsbalken im Randbereich einer Unterfederung um 90° nach unten umzuknicken, um so einen durchgehenden seitlichen Rand der Unterfederung zu erzeugen, der sich vorteilhaft auf die Formfestigkeit der gesamten Unterfederung auswirkt.In order to make the networking particularly practical, the longitudinal beams and the crossbars are provided with predetermined breaking points for separating the ends, so that, for example, the beams in the edge region of a Unterfederungsfläche not project beyond the contour of the Unterfederungselemente. It is also conceivable to bend the longitudinal beams in the edge region of a lower suspension by 90 ° down so as to produce a continuous lateral edge of the lower suspension, which has an advantageous effect on the dimensional stability of the entire spring base.

Entsprechend einer weiteren vorteilhaften Ausgestaltung der Erfindung sind die nach oben gerichteten freien Oberflächen der Kupplungselemente ebenfalls als Auflagerflächen ausgebildet, so dass eine hohe aufgebrachte Flächenlast besser von der vergrößerten Auflagerfläche der erfindungsgemäßen Unterfederung aufgenommen werden kann, wobei es von besonderen Vorteil ist, dass die Längsbalken der Kupplungselemente parallel in Längsrichtung eng neben den Unterfederungselementen verlaufen, so dass ein Längsspalt zwischen den Unterfederungselementen in Höhe der Auflagerflächen überdeckt wird.According to a further advantageous embodiment of the invention, the upwardly directed free surfaces of the coupling elements are also formed as bearing surfaces, so that a high applied surface load can be better absorbed by the enlarged bearing surface of the invention spring suspension, it being particularly advantageous that the longitudinal beams of Coupling elements run parallel to each other in the longitudinal direction closely to the Unterfederungselementen, so that a longitudinal gap between the lower suspension elements is covered in height of the bearing surfaces.

Die erfinderischen Kupplungselemente können dabei entweder nur im Bereich der oberen Auflagerfläche aufgelagert sein oder auch im Bereich der unteren Auflagerfläche, so dass eine beliebig stabile Vernetzung der Unterfederungselemente zur Verfügung gestellt werden kann.The inventive coupling elements can either be superimposed only in the region of the upper support surface or in the region of the lower support surface, so that an arbitrarily stable networking of the lower suspension elements can be provided.

Bei einer besonders bevorzugten Ausgestaltung der Erfindung greifen die Rastmittel der Querbolzen der Kupplungselemente von oben her oder auch von innen in die Rastenaufnahmen der Unterfederungselemente ein, wodurch sich die Montage wesentlich erleichtert. Sie könnten jedoch auch seitlich von den Stirnseiten der Unterfederungselemente her in entsprechende Aufnahmen eingreifen, wenn solche Ausführungsformen, etwa aus optischen Gesichtspunkten, gewünscht sein sollten.In a particularly preferred embodiment of the invention, the locking means of the transverse pin of the coupling elements engage from above or from the inside into the detent recesses of the lower suspension elements, whereby the assembly significantly easier. However, they could also engage laterally from the end faces of the lower suspension elements into corresponding receptacles, if such embodiments, for example from an optical point of view, should be desired.

Die einzelnen Unterfederungselemente 1 bestehen aus liegenden, elliptisch-zylindrischen Mantelkörpern mit im Querschnitt konkav eingeformten Haupt- und Nebenscheiteln mit einer Vielzahl von Flächenausnehmungen 20 in ihren Mantelflächen, deren Oberflächen die unteren und oberen Auflagerflächen 2 bilden.The individual lower suspension elements 1 consist of horizontal, elliptical-cylindrical shell bodies with a concave main and secondary crest formed with a plurality of surface recesses 20 in their lateral surfaces whose surfaces form the lower and upper bearing surfaces 2.

Vom Schutz umfasst, aber zeichnerisch nicht dargestellt, sind auch andere bekannte Unterfederungselemente mit oberen und unteren Auflagerflächen, auch mit in Draufsicht nicht in etwa rechteckigen Unterfederungselementen 1 oder auch solche nur mit oberen Auflagerflächen und anders gestalteten Fußteilen und mit anderen dazwischen angeordneten elastischen Elementen, die auf die beschriebene Art und Weise miteinander vernetzt werden können.Covered by the protection, but not shown in the drawing, other known Unterfederungselemente with upper and lower bearing surfaces, not in plan view with approximately rectangular Unterfederungselementen 1 or even only with upper bearing surfaces and differently shaped foot parts and other interposed elastic elements, the can be networked together in the manner described.

Die vorliegende Unterfederung wird von vernetzten Unterfederungselementen 1 gebildet, die in Längsrichtung 9 hintereinander angeordnet sind und jedes in einer rechtwinkligen Querrichtung 10 zur Längsrichtung 9 in den seitlichen Randbereichen seiner Auflagerflächen 2 beidseitig jeweils mindestens eine Aufnahmen 7;17 für jeweils ein Ende eines Querbalkens 5;15;25;35 eines starren Kupplungselementes 3;13;23;33 aufweist.The present base is formed by cross-linked spring elements 1, which are arranged one behind the other in the longitudinal direction 9 and each in a right-angled transverse direction 10 to the longitudinal direction 9 in the lateral edge regions of its support surfaces 2 on both sides at least one receptacles 7, 17 for each end of a crossbar 5; 15, 25, 35 of a rigid coupling element 3, 13, 23, 33.

Eine erste Hauptvariante, wie sie in den Figuren 1-3 dargestellt ist, weist beidseitig jeweils zwei Aufnahmen 7 für zwei Kupplungselemente 3 auf. Die Aufnahmen 7 sind unmittelbar nebeneinander und kurz unterhalb der Auflagerflächen 2 im Bereich des nach innen eingeformten Scheitelbereichs angeordnet und zwar unmittelbar benachbart einer horizontalen Symmetrieachse durch die Unterfederungselemente 1, die rechtwinklig zur Längsrichtung 9 der Unterfederung verläuft.A first main variant, as in the Figures 1-3 is shown, on both sides in each case two receptacles 7 for two coupling elements 3. The receptacles 7 are arranged directly next to each other and just below the support surfaces 2 in the region of the inwardly molded apex region and directly adjacent to a horizontal axis of symmetry by the Unterfederungselemente 1, which is perpendicular to the longitudinal direction 9 of the lower suspension.

Die Kupplungselemente 3 weisen im wesentlichen eine Doppel-T-Profil-förmige Grundform auf, wobei die Querbalken 5 an ihren Enden 6 mit Rastmitteln 11 versehen sind, die mit Rastmitteln in den Aufnahmen 7 unterhalb der Auflagerflächen 2 der Unterfederungselemente 1 zusammenwirken.The coupling elements 3 have essentially a double-T-profile-shaped basic shape, wherein the transverse bar 5 is provided at its ends 6 with locking means 11 are, which cooperate with locking means in the receptacles 7 below the bearing surfaces 2 of the suspension elements 1.

Jedes einzelne Unterfederungselement 1 einer solchen Vernetzung wird von acht Kupplungselementen 3 im Verbund gehalten, nämlich von zwei unteren rechts und links nach vorne gerichteten, zwei unteren rechts und links nach hinten gerichteten, zwei oberen rechts und links nach vorne gerichteten und zwei oberen rechts und links nach hinten gerichteten Kupplungselementen 3, wodurch eine sehr hohe Seitenstabilität der gesamten Unterfederung zur Verfügung gestellt wird, die von der Ausführungsform der Unterfederungselemente 1 wesentlich unterstützt wird.Each individual lower suspension element 1 of such a network is held by eight coupling elements 3 in the composite, namely two lower right and left facing forward, two lower right and left rearward, two upper right and left forward and two upper right and left rearwardly directed coupling elements 3, whereby a very high lateral stability of the entire lower suspension is provided, which is substantially supported by the embodiment of the suspension elements 1.

Zeichnerisch nicht dargestellt sind Kupplungselemente 3, die in Draufsicht mit den darunter angeordneten Kupplungselementen 3 über elastische Verbindungsstege miteinander verbunden sind, wodurch eine zusätzliche Stabilität der Unterfederung zur Verfügung gestellt wird. Solche Kupplungselemente 3 können in ihren Längsbalken 4 zusätzlich mit zwei Knickstellen 19 ausgestattet sein, um im Endbereich einer Unterfederung, jeweils um 90° U-förmig umgeknickt, die letzten oberen und unteren Aufnahmen 7 miteinander zu verbinden und so einen Rahmen zu bilden.Zeichnerisch not shown are coupling elements 3, which are connected to each other in plan view with the underlying coupling elements 3 via elastic connecting webs, whereby an additional stability of the spring base is provided. Such coupling elements 3 may be additionally equipped in their longitudinal beams 4 with two kinks 19 to the end of a lower suspension, each bent by 90 ° U-shaped, to connect the last upper and lower seats 7 together and thus form a frame.

Bei einer zweiten Hauptvariante, wie sie in den Figuren 4-9 dargestellt ist, weist jedes Unterfederungselement 1 in Querrichtung 10 beidseitig jeweils nur eine Rastenaufnahme 17 im Bereich seiner Auflagerflächen 2 auf und die Kupplungselemente 13;23;33 sind mit Längsbalken 14 und Querbalken 15 ausgebildet, die an ihren Enden mit Rastmitteln 11,12;21;22;31;32 versehen sind, von denen die Rastmittel 11;12;21;22 der Querbalken 15;25;35 in den Rastenaufnahmen 17 der Unterfederungselemente 1 und die Rastmittel 31;32 der Längsbalken 14 mit korrespondierenden Rastmitteln 31;32 benachbarter Kupplungselemente 13;23;33 verrastet sind.In a second main variant, as in the Figures 4-9 is shown, each Unterfederungselement 1 in the transverse direction 10 on both sides only one catch receptacle 17 in the region of its bearing surfaces 2 and the coupling elements 13, 23, 33 are formed with longitudinal beams 14 and crossbar 15, which at their ends with locking means 11,12; ; 22; 31; 32 are provided, of which the latching means 11; 12; 21; 22 of the transverse beams 15; 25; 35 in the detent recesses 17 of the Unterfederungselemente 1 and the locking means 31; 32 of the longitudinal beams 14 with corresponding locking means 31; 32 adjacent Coupling elements 13, 23, 33 are locked.

In den zur Längsrichtung 9 seitlich ausgerichteten Bereichen der Unterfederungselemente 1 sind diese etwa im Bereich ihrer horizontalen Symmetrieachsen mit mehreren von außen nach innen hintereinander angeordneten Rastenaufnahmen 17 ausgestattet, in die Rastmittel 11;12;21;22 von Kupplungselementen 13;23;33 unterschiedlich tief so verrastet werden können, dass die einzelnen Unterfederungselemente 1 in unterschiedlichen Abständen zueinander vernetzt sind. Die Rastmittel 11;12;22 bestehen hier aus angeformten Vorsprüngen 12 und beidseitig der Querbalken 15;25;35 angeordneten Rastnasen 11;21;22, so dass eine Montage der Querbalken 15 von oben oder unten oder der Querbalken 35 unten oder oben von innen oder der Querbalken 25 seitlich von außen in die Rastenaufnahmen 17 der Unterfederungselemente 1 möglich ist.In the longitudinal direction 9 laterally aligned areas of the Unterfederungselemente 1 these are approximately in the region of their horizontal axes of symmetry equipped with a plurality of externally inwardly arranged one behind the other detent recesses 17, in the locking means 11, 12, 21, 22 of coupling elements 13, 23; can be locked so that the individual base elements 1 are crosslinked at different distances from each other. The locking means 11, 12, 22 consist here of integrally formed projections 12 and on both sides of the crossbars 15, 25, 35 arranged latching lugs 11, 21, 22, so that an assembly of the crossbar 15 from above or below or the crossbar 35 below or above from the inside or Crossbar 25 laterally from the outside into the detent recesses 17 of the Unterfederungselemente 1 is possible.

Die Kupplungselemente 13;23;33, die im wesentlichen kreuzförmig ausgebildet sind, weisen des Weiteren zusätzlich zu dem Querbalken 15;25;35 einen Längsbalken 14 auf, der an seinen Enden jeweils mit Rastmitteln 31;32 ausgestattet ist, die gegensätzlich zueinander ausgeführt sind, so dass die Enden von Längsbalken 14 benachbarter Kupplungselemente 13;23;33 miteinander verrastet werden können. Auch hier ist ein Ende eines Längsbalkens 14 mit von außen nach innen her mit mehreren hintereinander als Rastenaufnahmen ausgebildeten Rastmitteln 32 versehen, so dass die Unterfederungselemente 1 auch in einer Längsrichtung 9 einer Unterfederung in variablen Abständen miteinander vernetzt werden können.The coupling elements 13, 23, 33, which are substantially cross-shaped, furthermore have, in addition to the transverse bar 15, 25, 35, a longitudinal bar 14, which is equipped at its ends with latching means 31, 32, which are designed in opposite directions so that the ends of longitudinal beams 14 of adjacent coupling elements 13, 23, 33 can be locked together. Again, one end of a longitudinal beam 14 is provided with from outside to inside with several successively formed as a detent recesses 32 locking means so that the Unterfederungselemente 1 can be networked with each other in a longitudinal direction 9 of a spring suspension at variable intervals.

Bei größeren Unterfederungselementen 1 könnten auch zwei voneinander beabstandete Querbalken 15;25;35 die benachbarten Unterfederungselemente 1 miteinander verbinden, wobei die Kupplungselemente 13;23;33 dann etwa doppelkreuzförmig gestaltet wären, was zeichnerisch nicht dargestellt ist.In the case of larger under-suspension elements 1, two transverse bars 15, 25, 35 spaced apart from each other could also connect the adjacent under-suspension elements 1, wherein the coupling elements 13, 23, 33 would then be approximately double cross-shaped, which is not shown in the drawing.

Die Querbalken 5;15;25;35 und die Längsbalken 4;14 des Kupplungselementes 13;23;33 sind im Kreuzungsbereich oder über die Länge der Längsbalken 4;14 mit Sollbruchstellen oder Knickstellen 19 ausgestattet, so dass im Randbereich einer Unterfederungsfläche ein Vorstehen von Teilen des Kupplungselementes 3;13;23;33 durch einfaches Abbrechen oder Umbiegen dieser Teile vermieden werden kann.The transverse bars 5, 15, 25, 35 and the longitudinal bars 4, 14 of the coupling element 13, 23, 33 are provided with predetermined breaking points or kinks 19 in the crossing region or along the length of the longitudinal bars 4, 14, so that a protrusion of Parts of the coupling element 3, 13, 23, 33 can be avoided by simply breaking or bending these parts.

Die im Bereich der oberen Auflagerfläche 2 angeordneten Kupplungselemente 3;13;23;33 weisen nach oben eine Fläche auf, die ebenfalls als Auflagerfläche 2 für zu unterfedernde Auflagen ausgebildet ist.The arranged in the region of the upper support surface 2 coupling elements 3, 13, 23, 33 have upwardly on a surface which is also formed as a support surface 2 for unterfedernde pads.
