Description

Die Erfindung betrifft einen Bettrahmen mit zwei Rahmenlängsträgern und diese miteinander verbindenden Quertragern und einer zwischen den Rahmenlängsträgern angeordneten Matratzenauflage, insbesondere Federholzleisten, bei dem am Fußende an den Innenseiten der beiden Rahmenlängsträger jeweils eine Stützschiene mit einem Rahmenlängsträger über zwei im wesentlichen gleichgerichtete Lenker unterschiedlicher Länge verbunden ist, die zwischen der Horizontalen und jeweils sich selbst einen zum Fußende offenen, spitzen Winkel bilde, sowie ein entgegengesetzt geneigte Rasthebel mit seinem oberen Ende am zugeordneten Rahmenlängsträger angelenkt ist und mit einer seitlichen Rastnase an seinem unteren Ende in einer Führung derart verschieblich gelagert ist, daß die Rastnase in eine beliebige von mehreren Rastenausnehmungen einrastbar und über die Endstellung hinaus wieder in die Ausgangsstellung rückführbar ist.The invention relates to a bed frame with two frame side members and cross members connecting them to one another and a mattress support, in particular spring wooden strips arranged between the frame side members, in which at the foot end on the inner sides of the two frame side members a support rail is connected to a frame side member via two essentially rectified links of different lengths , which forms an open angle at the foot end between the horizontal and each itself, and an oppositely inclined locking lever is articulated with its upper end on the associated frame longitudinal member and is so displaceably mounted in a guide with a lateral locking lug at its lower end that the locking lug can be snapped into any one of several locking recesses and can be returned to the starting position beyond the end position.

Bei einem bekannten Bettrahmen dieser Art(DF-GM 78 01 131) ist der längere bzw. am äußersten Fußende des Bettrahmens zwischen Längsträger und Stützschiene angeordnete Lenker direkt mit den Rastenausnehmungen versehen und längs dieses Lenkers ist eine schieberartig ausgebildete Führung für die Rastnase des Rasthebels gleitbar angeordnet, d. h. der Rasthebel stützt sich unmittelbar an dem betreffenden Lenker ab, was relativ ungünstige Hebelverhältnisse und daraus resultierend große Kräfte in den betreffenden Teilen und Gelenken bewirkt, insbesondere in der besonders häufig eingestellten niedrigsten Hochschwenkstellung des Fußendes des betreffenden Bettrahmens. Vor allem aber bedingt die Anordnung der Teile zueinander bei der bekannten Konstruktion, daß die Rastnase des Rasthebels durch eine Feder in Eingriff mit den Rastenausnehmungen an dem betreffenden Lenker gebracht und gehalten werden muß. Solche federn können aber leicht die Ursache für Fehlfunktionen sein bzw. nach bestimmten Gebrauchszeiten ausfallen, womit die gesamte Verstellvorrichtung funktionsunfähig wird.In a known bed frame of this type (DF-GM 78 01 131), the longer or at the outermost foot end of the bed frame between the longitudinal member and the support rail is directly provided with the notches and along this handlebar a slide-shaped guide for the latch of the latch lever is slidable arranged, d. H. the locking lever is supported directly on the handlebar in question, which causes relatively unfavorable lever ratios and, as a result, large forces in the parts and joints in question, particularly in the particularly frequently set lowest pivoting position of the foot end of the bed frame in question. Above all, however, the arrangement of the parts relative to one another in the known construction means that the latching lug of the latching lever must be brought into engagement with the latching recesses on the relevant handlebar and held by a spring. However, such springs can easily be the cause of malfunctions or fail after certain periods of use, making the entire adjusting device inoperable.

Aufgabe der Erfindung ist die Schaffung eines Bettrahmens der betreffenden Art, bei dem unter Aufrechterhaltung seiner Hauptvorteile, nämlich relativ einfacher Ausgestaltung der Gesamtkonstruktion und der Unabhängigkeit von Art und Längserstreckung der beidseitigen Stützschienen am Bettgestell, die Stabilität der Verstellung sowie deren Funktionssicherheit noch weiter verbessert wird.The object of the invention is to provide a bed frame of the type in which, while maintaining its main advantages, namely a relatively simple design of the overall construction and the independence of the type and longitudinal extension of the support rails on both sides of the bed frame, the stability of the adjustment and its functional reliability is further improved.

Bei einem Bettrahmen der eingangs bezeichneten Art wird diese Aufgabe gemäß der Erfindung dadurch gelöst; daß die mit den Rastenausnehmungen versehene Führung an der Stützschiene in deren Längsrichtung sich erstreckend befestigt ist und daß die Rastnase nach dem beim Anheben des Fußendes erfolgenden Passieren der Rastenausnehmungen über eine Auflauffläche und eine Umlenkweiche unter Wiederabsenken des Fußendes in die Ausgangsstellung zurückgelangt.With a bed frame of the type described in the introduction, this object is achieved according to the invention; that the guide provided with the catch recesses is attached to the support rail extending in the longitudinal direction thereof, and that the latching nose, after passing through the catch recesses when the foot end is lifted, returns to the starting position via a run-up surface and a deflection switch while lowering the foot end again.

Aufgrund dieser Ausbildung ist erkennbar, daß sich wesentlich günstigere Hebelverhältnisse und damit auch geringere Kräfteeinleitungen an günstigeren Stellen ergeben, indem sich nämlich die beidseitigen Rasthebel unmittelbar an den auf dem Bettgestell aufliegenden Stützschienen abstützen, wobei wichtig ist, daß aufgrund der Anordnung der Teile zueinander auf jegliche Federelemente verzichtet werden kann, so daß von solchen Federelementen ausgehende Fehlfunktionen bzw. Ausfälle nicht zu befürchten sind.Due to this design, it can be seen that there are much more favorable lever ratios and thus also lower force inputs at more favorable locations, namely because the two-sided locking levers are supported directly on the support rails resting on the bed frame, it being important that due to the arrangement of the parts to one another Spring elements can be dispensed with, so that malfunctions or failures arising from such spring elements are not to be feared.

Zwar ist die Art und Weise der Verrastung grundsätzlich bereits bekannt (CH-PS 533 970), dort aber in anderer Zuordnung der betreffenden Verrastung zu den übrigen Teilen der Verstellvorrichtung bzw. dem verschwenkbaren Bettrahmenteil. So erstreckt sich bei dem bekannten Bettrahmen der am verschwenkbaren Bettrahmenteil angelenkte Rasthebel im wesentlichen in gleiche Richtung wie das zu verschwenkende Bettrahmenteil, was wiederum ungünstige Hebel- und daraus resultierende Kraftübertragungen bedingt.Although the type of latching is fundamentally already known (CH-PS 533 970), it is there that the latching in question is assigned to the other parts of the adjusting device or the pivotable bed frame part in a different way. Thus, in the known bed frame, the latching lever articulated on the pivotable bed frame part extends essentially in the same direction as the bed frame part to be pivoted, which in turn causes unfavorable lever and force transmissions resulting therefrom.

In Weiterbildung der Erfindung empfiehlt es sich, die Umlenkweiche aus einem einseitig angelenkten winkelförmigen starren Gleitstück zu bilden, einmal weil dadurch die Stabilität der horizontalen Gleitfläche noch erhöht wird und zum anderen weil durch Anlage des anderen vertikalen Winkelschenkels am Führungsgehäuse die Lagerung der Umlenkweiche besonders stabil wird.In a further development of the invention, it is advisable to form the deflector from a one-sided articulated, angular, rigid slider, firstly because this increases the stability of the horizontal sliding surface and secondly because the bearing of the deflector becomes particularly stable by contacting the other vertical angled arm on the guide housing .

Schließlich kann man die den beiden Rahmenlängsträgern zugeordneten Rastlenker auch noch durch eine Querstrebe miteinander verbinden, wodurch auch bei einseitigem Anheben des Fußendes des Bettrahmens eine gleichmäßige Rastung an beiden Seiten des Fußendes gewährleistet wird. Derartige durch eine Querstrebe verbundene Rasthebel sind bei einem Bettrahmen nach der DE-OS 23 15 337 bzw. der CH-FS 533 970 bekannt.Finally, the locking links assigned to the two longitudinal frame members can also be connected to one another by means of a cross strut, which ensures even locking on both sides of the foot end even when the foot end of the bed frame is raised on one side. Such locking levers connected by a cross strut are known in a bed frame according to DE-OS 23 15 337 or CH-FS 533 970.

Bei dem in fig. 1 und 2 wiedergegebenen Ausführungsbeispiel besteht ein insgesamt mit 1 bezeichnetes Bettgestell einfachster Ausgestaltung aus zwei Paneelfüßen 2, die mit Längszargen 3 befestigt, vorzugsweise verschraubt sind. Zwischen den Enden der Längszargen 3 sind Querzargen 4 mittels Verschraubung befestigt.With the in fig. 1 and 2 shown embodiment, there is a bed frame with the simplest design, generally designated 1, of two panel feet 2 which are fastened with longitudinal frames 3, preferably screwed together. Cross frames 4 are fastened by screwing between the ends of the longitudinal frames 3.

Der eigentliche, insgesamt mit 5 bezeichnete Bettrahmen besteht im wesentlichen aus zwei Rahmenlängsträgern 7 und diese miteinander verbindenden Querträgern 6 und an den Rahmenlängsträgern 7 in üblicher Weise befestigten Federleisten 8, wobei jedem Rahmenlängsträger 7 an seinem Fußende eine winkelförmige Stützschiene 9 derart zugeordnet ist, daß der Rahmenlängsträger 7 in abgesenkter Stellung auf dem waagerechten Schenkel der Stützschiene 9 aufruht. Am Kopfende ist noch ein nicht näher beschriebenes verschwenkbares Kopfteil ausgebildet, wie insbesondere Figur 1 zeigt.The actual bed frame, designated overall by 5, consists essentially of two frame side members 7 and cross members 6 connecting them to one another and spring strips 8 fastened to the frame side members 7 in the usual manner, with each frame side member 7 being assigned an angular support rail 9 at its foot end such that the Frame side member 7 rests in the lowered position on the horizontal leg of the support rail 9. At the head end a pivotable head part is not formed, as shown in particular in Figure 1.

Zwischen Rahmenlängsträger 7 und Stützschiene 9 sind zwei im wesentlichen gleichgerichtete Lenker 10 und 11 unterschiedlicher Länge angelenkt, derart, daß diese in jeder möglichen Stellung zwischen der Stützschiene 9 und jeweils sich selbst einen zum Fußende offenen Winkel bilden.Between frame longitudinal member 7 and support rail 9, two substantially rectified links 10 and 11 of different lengths are articulated in such a way that they form an open angle at the foot end in every possible position between the support rail 9 and itself.

Ferner ist am Rahmenlängsträger 7 das obere Ende eines Rasthebels 12 angelenkt, an dessen unterem Ende eine Rastnase 13 angeordnet ist.Furthermore, the upper end of a locking lever 12 is articulated on the frame longitudinal member 7, at the lower end of which a locking nose 13 is arranged.

Am dem Fußende zugerichteten Ende der Stützschiene 9 ist ferner eine Führung 14 befestigt, welche zwei Rastausnehmungen 15 und 16 aufweist, denen jeweils eine Auflauffläche 17 bzw. 18 vorgeschaltet ist. Ferner ist an einer vertikalen Wandung 19 der Führung 14 eine winkelförmige Umlenkweiche 20 angelenkt, deren freies Ende auf einer am kopfseitigen Ende der Führung 14 angeordneten weiteren Auflauffläche 21 aufruht. Oberhalb des horizontalen Schenkels der Umlenkweiche 20 ist eine kopfseitige vertikale Begrenzungsfläche 22 sowie eine obere horizontale Begrenzungsfläche 23 ausgebildet. Wie figur 4 zeigt, greift die Rastnase 13 des Rasthebels 12 von der Innenseite her in die Führung 14 ein und kann dort die in Figur 3 gestrichelt angedeuteten Stellungen und Führungsbahnen durchlaufen. Die beidseitigen Stützschienen 9 sind miteinander über eine Querstrebe 24 verbunden, ebenso wie die beidseitigen Rasthebel 12 durch eine weitere Querstrebe 25.At the end of the support rail 9 facing the end, a guide 14 is also fastened, which has two latching recesses 15 and 16, each of which is preceded by a run-up surface 17 and 18, respectively. Furthermore, an angular deflector 20 is articulated on a vertical wall 19 of the guide 14, the free end of which rests on a further contact surface 21 arranged at the head end of the guide 14. Above the horizontal leg of the deflection switch 20, a vertical boundary surface 22 on the head side and an upper horizontal boundary surface 23 are formed. As FIG. 4 shows, the catch 13 of the catch lever 12 engages in the guide 14 from the inside and can pass through the positions and guideways indicated by dashed lines in FIG. 3. The support rails 9 on both sides are connected to one another via a cross strut 24, as are the locking levers 12 on both sides by a further cross strut 25.

Die Abmessungen der Lenker 10 und 11 sowie des Rasthebels 12 und deren Anlenkpunkte an Stützschiene 9 und Rahmenlängsträger 7 sind derart gewählt, daß einerseits beim Anheben des Fußendes die Anlenkpunkte der Lenker 10 und 11 am Rahmenlängsträger 7 auf einer wechselnd geneigten Geraden liegen und andererseits die Rastnase 13 des Rasthebels 12 passend in die entsprechenden Rastausnehmungen 16 der Führung 14 einrastet.The dimensions of the handlebars 10 and 11 and the locking lever 12 and their articulation points on the support rail 9 and frame side member 7 are selected such that, on the one hand, when the foot end is raised, the articulation points of the handlebars 10 and 11 on the frame side member 7 lie on an alternating inclined straight line and, on the other hand, the locking lug 13 of the locking lever 12 snaps into the corresponding locking recesses 16 of the guide 14.

Die Wirkungsweise der am Bettrahmen 5 angeordneten Verstellmittel ist wie folgt:The operation of the adjusting means arranged on the bed frame 5 is as follows:

Wird das Fußende des Bettrahmens 5 angehoben, so gelangen die beidseitigen Rastnasen 13 aus der in Fig. 3 gestrichelt wiedergegebenen Ausgangsstellung 1 über die Auflauffläche 17 in die Rastenausnehmung 15 (Stellung 11 der Rastnase 13) und bei weiterem Anheben über die Auflauffläche 18 in die Rastenausnehmung 16 (Stellung 111 der Rastnase 13), derart, daß der Bettrahmen 5 zwei mögliche Neigungsstellungen einnimmt. Zum Absenken des Bettrahmens 5 wird das Fußende deaselben weiter angehoben, wobei die beidseitigen Rastnasen 13 über die Auflauffläche 21 die Umlenkweiche 20 passieren (Stellung IV der Rastnase 13) und dann über den waagerechten Schenkel der winkelförmig ausgebildeten Umlenkweiche 20 beim Absenken des Fußendes zurücklaufen (Stellung V der Rastnase 13) und schließlich in die Stellung 1 zurückfallen.If the foot end of the bed frame 5 is raised, the latches 13 on both sides pass from the starting position 1 shown in dashed lines in FIG. 3 via the ramp 17 into the latch recess 15 (position 11 of the latch 13) and with further lifting via the ramp 18 into the latch recess 16 (position 111 of the locking lug 13), such that the bed frame 5 assumes two possible inclination positions. To lower the bed frame 5, the foot end of the same is raised further, the latching lugs 13 on both sides passing the deflector 20 via the run-up surface 21 (position IV of the latching lug 13) and then running back over the horizontal leg of the angular deflector 20 when the foot end is lowered (position V of the locking lug 13) and finally fall back into position 1.
