Ruhevorrichtung gemaß dem Oberbegriff des Anspruchs 1.The invention relates to a spring base for cross slats of a slatted frame, in particular a bed and the like. Resting device according to the preamble of claim 1.

Bei einer bekannten Unterfederung für Querlatten eines Lattenrostes gemäß EP-PS 0 150 873 sind die Querlatten jeweils endseitig von einer im wesentlichen ein V-förmiges Profil aufweisenden Blattfeder gehalten, deren unterer Schenkel mit der Tragleiste eines Rahmens verschraubt ist und auf dessen oberen freiem Schenkel die Querlatte in einem gesonderten Aufnahmeteil aufgenommen ist. Ein derartiger metallischer Stützkörper ist in der Herstellung und in der Montage aufwendig, wobei eine Variation der Federhärte zur Anpassung an unterschiedliche Belastungen nur in engen Grenzen möglich ist.In a known spring base for crossbars of a slatted base according to EP-PS 0 150 873, the crossbars are each held at the end by a substantially V-shaped leaf spring, the lower leg of which is screwed to the support bar of a frame and on the upper free leg of which Crossbar is included in a separate receiving part. Such a metallic support body is complex to manufacture and assemble, with a variation of the spring hardness to adapt to different loads being possible only within narrow limits.

Der Erfindung liegt die Aufgabe zugrunde, eine nichtmetallische Unterfederung für Querlatten eines Lattenrostes zu schaffen, die mit geringem Aufwand herstellbar und montierbar ist.The invention has for its object to provide a non-metallic spring base for crossbars of a slatted frame, which can be produced and assembled with little effort.

Ausgehend von einer Unterfederung der eingangs angegebenen Art wird diese Aufgabe nach der Erfindung durch eine Ausgestaltung mit den kennzeichnenden Merkmalen des Anspruchs 1 gelöst. Hinsichtlich wesentlicher weiterer Ausgestaltungen wird auf die Ansprüche 2 bis 15 verwiesen.Starting from a spring base of the type specified at the outset, this object is achieved according to the invention by an embodiment having the characterizing features of claim 1 solved. With regard to essential further refinements, reference is made to claims 2 to 15.

Die Erfindung schafft eine Unterfederung für einen Lattenrost, dessen Querlatten endseitig in dem elastomeren, als Biegefeder wirksamen Stützkörper freitragend unmittelbar aufgenommen sind und dessen Stützkörper ohne zusätzliche Montagehilfsmittel in die Einbaulage einsetzbar sind. Der den Stützkörper bildende elastische Formteil ist als elastomeres Kunststoff- oder Gummiteil mit geringem Aufwand herstellbar, korrosionsfest und leicht an kundenspezifische Belastungen anpaßbar. Durch einfache Steckverbindungen können elastische Formteile mit geringem Aufwand schnell und beliebig zusammengestellt und ausgewechselt werden, so daß der Lattenrost bereichsweise oder vollständig mit unterschiedliche Federhärten aufweisenden Formteilen versehen werden kann, die dennoch als Baueinheit handhabbar sind.The invention provides a spring base for a slatted frame, the transverse slats of which are received directly at the ends in the elastomeric support body, which acts as a spiral spring, and whose support bodies can be inserted into the installation position without additional assembly aids. The elastic molded part forming the support body can be produced as an elastomeric plastic or rubber part with little effort, is corrosion-resistant and can easily be adapted to customer-specific loads. By means of simple plug-in connections, elastic molded parts can be put together and replaced quickly and with little effort, so that the slatted frame can be partially or completely provided with molded parts with different spring hardnesses, which can nevertheless be handled as a structural unit.

In Fig. 1 ist eine Bettstelle dargestellt, deren einen Lattenrost 1 bildenden Querlatten 2 jeweils endseitig auf einer mit der Seitenwand 3 eines Rahmens verbundenen Tragleiste 4 aufliegen. Die Querlatten 2 sind dabei jeweils endseitig über einen Stützkörper 5 in vertikaler Belastungsrichtung 6 federnd gelagert.In Fig. 1, a bed is shown, the cross slats 2 forming a slatted frame 1 each end on a support bar 4 connected to the side wall 3 of a frame. The crossbars 2 are each resiliently mounted at the ends via a support body 5 in the vertical loading direction 6.

Der Stützkörper 5 umfaßt, wie dies aus der vergrößerten Schnittdarstellung gemäß Fig. 2 deutlich wird, ein einstückiges elastisches Formteil 7 aus elastomerem Material, das im oberen Bereich 8 die Querlatten 2 unmittelbar aufnimmt und mit einem unteren Auflageende 9 auf der Tragleiste 4 aufliegt. In der dargestellten Einbaulage weist das Formteil 7 ein zur Hauptbelastungsrichtung 6 geneigtes Biegeprofil auf, das im Querschnitt Bereiche unterschiedlicher Wanddicke 10,11 darbietet.The support body 5 comprises, as is clear from the enlarged sectional view according to FIG. 2, a one-piece elastic molded part 7 made of elastomeric material, which directly receives the crossbars 2 in the upper region 8 and rests on the support strip 4 with a lower support end 9. In the installation position shown, the molded part 7 has a bending profile which is inclined with respect to the main load direction 6 and which has different cross-sectional areas Wall thickness 10.11 offers.

Das Formteil 7 kann durch Trennschlitze 12 von einer Profilleiste bereichsweise in einzelne Segmente 13 unterteilt sein. Stattdessen können auch den Segmenten 13 entsprechend gesonderte Formteile 7 vorgesehen sein, die durch Abtrennen von einer Profilleiste gebildet sein können. Die Segmente 13 ermöglichen voneinander unabhängige Federbewegungen auf unterschiedlichen Biegewegen.The molded part 7 can be divided into individual segments 13 by separating slots 12 from a profile strip. Instead, separate molded parts 7 can also be provided corresponding to the segments 13, which can be formed by separating them from a profiled strip. The segments 13 enable mutually independent spring movements on different bending paths.

In der Ausführung gemäß Fig. 2 sind die Formteile 7 im Bereich des Auflageendes 9 über ein einstückiges Verbindungsteil 14 vereinigt, das gleitbeweglich auf der Tragleiste 4 abgestützt ist und in zweckmäßiger Ausbildung auf einer verschleißmindernden Gleitplatte 15 aufliegt.In the embodiment according to FIG. 2, the molded parts 7 are combined in the area of the support end 9 via a one-piece connecting part 14, which is supported in a sliding manner on the support bar 4 and, in an expedient embodiment, rests on a wear-reducing sliding plate 15.

Am oberen Ende 8 des Formteiles 7 ist die Querlatte 2 in einen als Durchgangsöffnung 17 ausgebildeten Formeingriff 16 aufgenommen, der ein Einschieben der Querlatte 2 bis zur Anlage an die Seitenwand 3 ermöglicht. Mit der Ausbildung des Formeingriffs 16 als Sacköffnungen 17' (Fig. 4 und Fig. 5) ist eine weitere zweckmäßige Steckverbindung zwischen Formteilen 7 und Querlatten 2 erreichbar. Grundsätzlich können die Durchgangsöffnung 17 bzw. die Sacköffnung 17' auch an der Querlatte 2 ausgebildet sein, so daß mit einem am oberen Bereich 8 des Formteiles 7 angeformten Einsteckzapfen (nicht dargestellt) die Steckverbindung erreichbar ist.At the upper end 8 of the molded part 7, the crossbar 2 is received in a shaped engagement 16 designed as a through opening 17, which enables the crossbar 2 to be pushed in until it abuts the side wall 3. With the formation of the shape engagement 16 as a bag opening 17 '(Fig. 4 and Fig. 5) a further useful plug connection between the molded parts 7 and crossbars 2 can be achieved. In principle, the through-opening 17 or the pocket opening 17 'can also be formed on the crossbar 2, so that the plug-in connection can be reached with an insertion pin (not shown) formed on the upper region 8 of the molded part 7.

Die in der Fig. 3 veranschaulichte Ausführung des Formteiles 7 ist mit einem erweiterten unteren Auflageende 9 ausgebildet, das mit konformen Anlageflächen 18 an der Tragleiste 4 in Betriebsstellung lagestabil abgestützt ist. Die Verbindung der einzelnen Segmente 13 in Längsrichtung und damit parallel zur Tragleiste 4 ist dabei dadurch erreicht, daß im Bereich der Auflageenden 9 ein förmlich angepaßtes Verbindungsteil 21 in einem Formkanal 19 vorgesehen ist. Ein weiterer Formkanal 20 kann, zumindest in einigen Segmenten 13, ein Einsatzteil 22 mit Spiel aufnehmen, das die Federcharakteristik verändert.The embodiment of the molded part 7 illustrated in FIG. 3 is designed with an extended lower support end 9, which is supported in a stable position in the operating position with conforming contact surfaces 18 on the support bar 4. The connection of the individual segments 13 in the longitudinal direction and thus parallel to the support bar 4 is achieved in that a formally adapted connecting part 21 is provided in a molding channel 19 in the region of the support ends 9. Another molding channel 20 can, at least in some segments 13, accommodate an insert 22 with play, which the Spring characteristics changed.

Eine vertikale Abstützung des Auflageendes 9 ist durch einen auf der Tragleiste 4 lagestabil auflegbaren Formansatz 23 gegeben.A vertical support of the support end 9 is provided by a shape attachment 23 which can be placed on the support bar 4 in a stable position.

Am oberen Ende 8 des Formteiles 7 gemäß Fig. 3 ist die Querlatte 2 in der Durchgangsöffnung 17 über eine Auskleidung 24 abgestützt und reicht bis nahe an die Seitenwand 3 heran. Dabei kann sich die Querlatte 2 an der Seitenwand 3 mit einem elastischen Abschlußteil 25 abstützen, das eine Gleit- und Dämpfungsfunktion erfüllen kann. Dies gilt auch für die Ausführungsform gemäß Fig. 2 und Fig. 6.At the upper end 8 of the molded part 7 according to FIG. 3, the crossbar 2 is supported in the through opening 17 by a lining 24 and extends close to the side wall 3. The crossbar 2 can be supported on the side wall 3 with an elastic end part 25, which can fulfill a sliding and damping function. This also applies to the embodiment according to FIGS. 2 and 6.

Das Biegeprofil des Formteiles 7 weist in der Darstellung gemäß Fig. 2 eine zum oberen Ende 8 hin gleichmäßig zunehmende Wanddicke auf, wobei das Profil durch zwei konvex zur Seitenwand 3 gewölbte Formradien 26,27 gebildet ist. Mit diesen variabel zu gestaltenden Formradien 26,27 ist der Hauptteil 28 des Formteiles 7 mit verschiedenen Bogenformen zwischen dem oberen Ende 8 und dem Auflageende 9 in der Federhärte an unterschiedliche Belastungen anpaßbar.The bending profile of the molded part 7 has, in the illustration according to FIG. 2, a wall thickness which increases uniformly towards the upper end 8, the profile being formed by two radii 26, 27 curved convexly to the side wall 3. With these variably designed shape radii 26, 27, the main part 28 of the molded part 7 can be adapted to different loads in spring hardness with different arch shapes between the upper end 8 and the support end 9.

Das Biegeprofil ist gemäß Fig. 3 mit einer sich zum oberen Ende 8 hin gleichmäßig verringernden Wanddicke 29,30 ausgebildet, wobei die Formradien 31,32 konvergierend aufeinanderzu- und in die Formausnehmungen 16 einlaufen. Dabei haben sie an ihren Enden einen annähernd horizontalen Verlauf.According to FIG. 3, the bending profile is designed with a wall thickness 29, 30 which decreases uniformly towards the upper end 8, the form radii 31, 32 converging towards one another and entering the form recesses 16. They have an almost horizontal course at their ends.

In Fig. 4 ist das Formteil 7 mit einem konkav zur Seitenwand 3 gerichteten Biegeprofil ausgebildet, wobei von dem verstärkten Hauptteil 28 ausgehend die Wanddicken 33,34 zum oberen Ende 8 und zum unteren Auflageende 9 hin jeweils abnehmen. Im Bereich des Auflageendes 9 weist der Formkörper 7 einen Formkanal 35 auf, in den ein konformes Verbindungsteil 36 eingeschoben ist, das damit das Auflageende 9 im Eckbereich 37 zwischen Seitenwand 3 und Tragleiste 4 stabilisiert und benachbarte Formteile 7 zu einer Baueinheit zusammenfaßt.4, the molded part 7 is formed with a bending profile directed concavely to the side wall 3, the wall thicknesses 33, 34 decreasing towards the upper end 8 and towards the lower support end 9 starting from the reinforced main part 28. In the area of the support end 9, the molded body 7 has a molded channel 35 into which a conformal connecting part 36 is inserted, which thus stabilizes the support end 9 in the corner region 37 between the side wall 3 and the support strip 4 and adjacent molded parts 7 to form a structural unit summarizes.

Der Hauptteil 28 des Formteiles 7 gemäß Fig. 4 zeigt eine weitere Möglichkeit der Variation der Federkennlinie durch längsgerichtet durchgehende Hohlräume 38,39, die mit ihren unterschiedlichen Formen und ihrer Lage zueinander die Federhärte bei verschiedenen Verformungszuständen des Stützkörpers unterschiedlich beeinflussen. Die Zwischenstege 40,41,42 können je nach Ausrichtung und Form einen progressiven, degressiven, linearen oder sogar wechselnden Anstieg der Federhärte bewirken. Je nach ihrer Form und Ausrichtung kann damit ihre Lage in verschiedenen Verformungszuständen und damit das die Federhärte bestimmende Flächenträgheitsmoment des Gesamtquerschnitts bei unterschiedlichen Verformungszuständen gesteuert werden.The main part 28 of the molded part 7 according to FIG. 4 shows a further possibility of varying the spring characteristic curve through longitudinally continuous cavities 38, 39, which, with their different shapes and their position relative to one another, influence the spring hardness differently in different deformation states of the support body. Depending on the orientation and shape, the intermediate webs 40, 41, 42 can cause a progressive, degressive, linear or even changing increase in spring hardness. Depending on their shape and orientation, their position in different deformation states and thus the area moment of inertia of the total cross section determining the spring hardness can be controlled in different deformation states.

In einer Ausführungsform des Formteils 7 gemäß Fig. 5, die ähnlich dem konvexen Biegeprofil in Fig. 4 ist, begrenzen die Formradien 31,32 lediglich den mittleren Hauptteil 28 und gehen dann in geradlinige Begrenzungslinien für die konvergierenden Wandbereiche 43,44 am oberen Ende 8 bzw. im Bereich des Auflageendes 9 über. In dieser Ausführungsform ist das Formteil 7 durch die Trennschlitze 12 in einzelne Segmente 13 unterteilt, die im Bereich des Auflageendes 9 einen Verbindungssteg 45 belassen, so daß eine gemeinsame Abstützung der Segmente 13 im Eckbereich 37 erreicht ist. Eines oder mehrere Segmente 13' (Fig. 5) können durch einen Schnitt im Bereich des Formradius 32 mit einer Trennfläche 32' versehen sein, so daß mit geringem Aufwand eine Variation der Federkennlinie an beliebigen Segmenten 13 erreichbar ist und unterschiedliche Belastungen aufnehmbar sind.In an embodiment of the molded part 7 according to FIG. 5, which is similar to the convex bending profile in FIG. 4, the molded radii 31, 32 only delimit the central main part 28 and then go into straight-line boundary lines for the converging wall regions 43, 44 at the upper end 8 or in the area of the support end 9 over. In this embodiment, the molded part 7 is divided by the separating slots 12 into individual segments 13, which leave a connecting web 45 in the region of the support end 9, so that a common support of the segments 13 in the corner region 37 is achieved. One or more segments 13 '(FIG. 5) can be provided with a separating surface 32' by a cut in the area of the mold radius 32, so that a variation of the spring characteristic on any segments 13 can be achieved with little effort and different loads can be absorbed.

Fig. 6 zeigt eine Ausführungsform des Formteiles 7 mit einem Biegeprofil, das zwei im wesentlichen symmetrische Wellenprofilschenkel 46,47 aufweist. Vom gemeinsamen verstärkten Hauptteil 28 ausgehend erstreckt sich der untere Wellenprofilschenkel 47 bis in den Bereich des Auflageendes 9 und liegt unmittelbar im Eckbereich 37 des Rahmens an.FIG. 6 shows an embodiment of the molded part 7 with a bending profile which has two essentially symmetrical wave profile legs 46, 47. Starting from the common reinforced main part 28, the lower wave profile leg 47 extends into the area of the support end 9 and lies directly in the corner area 37 of the frame.

Der obere Wellenprofilschenkel 46 erstreckt sich vom Hauptteil 28 wellenförmig bis in das obere Ende 8 des Formteiles 7 mit Durchgangsöffnung 17, in der eine Querlatte 2 aufgenommen ist. Die von wellenförmigen Formradien 48,49,50,51 gebildeten Wellenprofilschenkeln 46,47 verleihen dem Formteil 7 ein Biegeprofil mit besonders hoher Elastizität und progressiver Kennlinie.The upper corrugated profile leg 46 extends from the main part 28 in a wave shape into the upper end 8 of the molded part 7 with a through opening 17 in which a crossbar 2 is received. The wavy profile legs 46, 47 formed by wavy shape radii 48, 49, 50, 51 give the molded part 7 a bent profile with particularly high elasticity and progressive characteristic.

Zur Verbindung von selbständigen Segmenten 13 im Bereich ihrer Auflageenden 9 können die Formteile 7 wie in Fig. 7 und 8 dargestellt mit angeformten, lösbaren Verbindungsgliedern 52,53 versehen sein. Im Bereich das Auflageendes 9 sind dazu entsprechend ineinanderpassende Rasthaken 54 und Widerlager 55 ausgebildet.To connect independent segments 13 in the area of their support ends 9, the molded parts 7 can be provided with molded, releasable connecting members 52, 53, as shown in FIGS. 7 and 8. To this end, correspondingly interlocking latching hooks 54 and abutments 55 are formed in the area of the support end 9.

In Fig. 9 sind in einer Seitenansicht auf den Stützkörper 5 gemäß Fig. 5 dessen durch gleichmäßige Trennschlitze 12 gebildete Segmente 13 veranschaulicht, die dementsprechend in Belastungsrichtung 6 eine gleichmäßige Federung ermöglichen. Eine Änderung der Breite der Trennschlitze 12 bildet eine weitere Möglichkeit zur Veränderung der Federcharakteristik von Segmenten 13.In FIG. 9, a side view of the support body 5 according to FIG. 5 is illustrated by its segments 13 formed by uniform separation slots 12, which accordingly enable uniform suspension in the load direction 6. A change in the width of the separating slots 12 forms a further possibility for changing the spring characteristic of segments 13.

Weitere Variationen der Federkennlinie der Segmente 13 kann durch die Wandstärken im Bereich der Trennfläche 32' verringernden Schnitte (Fig. 5) und einer damit geschaffenen Veränderung der Trägheitsmomente an einzelnen Segmenten 13 erreicht werden. Mit dem Einbringen von Einsätzen oder Füllungen in die einzelnen Segmente 13 (nicht dargestellt) sind ebenfalls Veränderungen der Federcharakteristik möglich, so daß unterschiedliche Belastungen aufnehmbar sind.Further variations of the spring characteristic of the segments 13 can be achieved by the wall thicknesses in the area of the separating surface 32 ′ reducing cuts (FIG. 5) and a change in the moments of inertia on individual segments 13 created thereby. With the introduction of inserts or fillings into the individual segments 13 (not shown), changes in the spring characteristic are also possible, so that different loads can be absorbed.

Selbständige Formteile 7 sind zur Veränderung der Federcharakteristik mit geringem Aufwand und schnell auswechselbar, so daß in beliebiger Kombination Formkörper 7 unterschiedlicher Federhärte aneinandergereiht werden können und eine individuelle Unterfederung für die Querlatten 2 eines Lattenrostes 1 erbringen.Independent molded parts 7 can be changed quickly and easily to change the spring characteristics, so that molded bodies 7 of different spring hardness can be strung together in any combination and provide an individual spring base for the crossbars 2 of a slatted frame 1.
