Description

Die Erfindung bezieht sich auf einen in einer oberen Position reversierbaren Kopf- oder Fußsteller mit mehreren Stufenrastungen für verschwenkbare Rahmenteile wie beispielsweise Matratzenrahmen, bestehend aus einer/U-förmigen Zahnschiene, deren Anlenkende auf ein am Holz- oder Stahlrohrrahmen befestigtes unteres Befestigungselement aus zwei Winkeln lösbar aufsteckbar ist, einem einstückigen, zum Teil U-formähnlichen Träger mit zwei Anlenkstreben, deren elastische Anlenkenden mit nach außen ragenden Lagerzapfen in ein oberes Befestigungselement aus zwei Winkeln mit Drehöffnungen einklemmbar sind, einem Schwenkgelenk zum Verbinden des Gelenkendes der Zahnschiene mit dem Gelenkende des Trägers und einer am Träger angelenkten Stützstrebe, deren Rastende in den einzelnen Raststufen mit der jeweiligen Rastzahnung zusammenwirkt, und mit einem Schieber als Steuerelement zur rastfreien Rückführung des Kopf- oder Fußstellers in seine Ausgangslage.The invention relates to a reversible head or foot switch in an upper position with a plurality of step catches for pivotable frame parts such as mattress frames, consisting of a / U-shaped toothed rail, the articulation end of which can be detached from two angles on a lower fastening element fastened to the wooden or tubular steel frame is pluggable, a one-piece, partly U-shaped carrier with two articulation struts, the elastic articulation ends of which can be clamped with outwardly projecting bearing pins into an upper fastening element from two angles with rotary openings, a swivel joint for connecting the joint end of the toothed rail to the joint end of the carrier and a support strut articulated to the support, the detent end of which interacts with the respective detent toothing in the individual detent stages, and with a slide as a control element for the detent-free return of the head or foot switch to its initial position.

Bisher wurde in den meisten Fällen der Kopf- oder Fußsteller vor der Fertigstellung des Rahmens mittels eines Befestigungselementes, das fest mit dem entsprechenden Rahmenteil vernietet oder verschweißt wurde, mit diesem Rahmenteil verbunden. Dies hatte zur Folge, daß der Kopf- oder Fußsteller die Produktionsstraße für die Montage des Rahmens mit durchlaufen mußte, was Nachteile mit sich brachte. Es war nicht üblich, die Befestigungselemente und die Anlenkenden des Kopf- oder Fußstellers so auszubilden, daß die Befestigungselemente zwar vor der Rahmenmontage fest mit dem entsprechenden Rahmenteil verbunden und nach Durchlaufen der Montagestraße mit dem Kopf- oder Fußsteller kombiniert werden konnten.So far, in most cases the head or foot plate was connected to this frame part before the completion of the frame by means of a fastening element which was firmly riveted or welded to the corresponding frame part. As a result, the head or foot switch had to go through the production line for the assembly of the frame, which had disadvantages. It was not common to design the fastening elements and the articulation ends of the head or foot plate so that the fastening elements could be firmly connected to the corresponding frame part before the frame assembly and could be combined with the head or foot plate after passing through the assembly line.

Um die Herstellung und die Endmontage von Matratzenrahmen zu erleichtern ist es zwar bekannt geworden, Befestigungselemente so auszubilden, daß sie vor der Rahmenmontage mit dem entsprechenden Teil des Holz- oder Stahlrohrrahmens fest verbunden und anschließend mit einem Kopf- oder Fußsteller kombiniert werden konnten. Zwar wurde dadurch vermieden, daß die Kopf- oder Fußsteller die Montagestraße für den Rahmen mit durchlaufen mußten, jedoch wurden dadurch Nachteile in Kauf genommen.In order to facilitate the manufacture and final assembly of mattress frames, it has become known to design fastening elements in such a way that before the frame assembly, they could be firmly connected to the corresponding part of the wooden or tubular steel frame and then combined with a head or foot plate. Although this prevented the head or foot actuators from having to go through the assembly line for the frame, disadvantages were accepted.

In einem bekannt gewordenen Fall (vgl. Katalog der Lanz Industrie-Technik AG, Murgenthal / Schweiz für Liegemöbelbeschläge) bestand eine obere Befestigungsplatte für einen Kopf- bzw. Fußsteller aus zwei Winkeln und einer Bodenplatte, welche am beweglichen Rahmenteil befestigt wurde. Die entsprechenden Anlenkenden des Trägers des Kopf- bzw. Fußstellers wiesen Drehzapfen auf, die infolge der elastischen Ausbildung der Anlenkenden leicht in die Drehöffnungen der Winkel der Befestigungsplatte eingefügt werden konnten.In a case that became known (see catalog of Lanz Industrie-Technik AG, Murgenthal / Switzerland for reclining furniture fittings), an upper fastening plate for a head or foot plate consisted of two angles and a base plate, which was fastened to the movable frame part. The corresponding articulation ends of the support of the head or foot plate had pivots, which could easily be inserted into the rotary openings of the angles of the mounting plate due to the elastic design of the articulation ends.

Die unteren Befestigungsplatten zum Einhängen der Zahnstangen wiesen im Abstand vom Rahmenteil angeordnete flache Schwenkstücke auf, die nur einseitig mit der unteren Befestigungsplatte verbunden waren. Auf das freie Ende des Schwenkstückes konnten die entsprechenden Schwenköffnungen an den Anlenkenden der Zahnschienen seitlich aufgeschoben werden.The lower mounting plates for hanging the racks had spaced flat swivel pieces, which were only connected on one side to the lower mounting plate. The corresponding swivel openings on the articulated ends of the toothed rails could be pushed sideways onto the free end of the swivel piece.

Derartige Befestigungsplatten zum Anlenken der Kopf- und Fußsteller am Matratzenrahmen bzw. an den beweglichen Rahmenteilen sind verbesserungsbedürftig. Die unteren Befestigungsplatten für die Zahnschienen sind bei einem vertretbaren Material und Befestigungsaufwand anfällig gegen die ständig auf die Schwenkstücke ausgeübten Biegemomente. Die unteren Befestigungsplatten neigten dazu, sich im Laufe der Zeit zu lockern bzw. zu verbiegen, so daß eine ordnungsgemäße Anlenkung der Zahnschienen an den Matratzenrahmen auf Dauer gestört wurde.Such mounting plates for articulating the head and foot plates on the mattress frame or on the movable frame parts are in need of improvement. The lower fastening plates for the toothed rails are susceptible to the bending moments that are constantly exerted on the swivel pieces with an acceptable material and fastening effort. The lower mounting plates tended to loosen or bend over time, so that proper articulation of the toothed rails on the mattress frame was permanently disturbed.

Auch die nachträgliche Anbringung des Trägers an den bekannten oberen Befestigungsplatten waren problematisch, da die Anlenkenden der Träger elastisch, d.h. instabil waren, um die Montage von Hand im Akkord nicht zu beeinträchtigen. Die Anlenkenden für die Drehzapfen mußten von Hand leicht zusammendrückbar sein, um die Drehzapfen zwischen die Winkel der oberen Befestigungsplatten einführen zu können. Infolge der aufgezeigten Mängel der unteren und oberen Befestigungsplatten konnte eine stabile Verbindung zwischen den Befestigungsplatten und den Kopf- oder Fußstellern auf Dauer nicht sichergestellt werden.The subsequent attachment of the carrier to the known upper mounting plates was problematic, since the articulation ends of the carrier were elastic, ie unstable, so as not to impair assembly by hand in a chord. The pivot ends for the pivots had to be easily compressible by hand in order to be able to insert the pivots between the angles of the upper fastening plates. As a result of the shown Defects of the lower and upper mounting plates could not be guaranteed a stable connection between the mounting plates and the head or foot plates in the long run.

Bekanntgeworden ist schließlich auch ein Kopf- oder Fußsteiler mit mehreren Stufenrastungen nach dem Oberbegriff des unabhängigen Anspruches 1, bei dem das untere Befestigungselement zwei Winkel aufweist und das obere Befestigungselement aus zwei Winkeln mit Drehöffnungen besteht, wobei die elastischen Anlenkenden des Trägers nach außen ragende lagerzapfen aufweisen (EP-A-0 291 840).Finally, a head or foot divider with a plurality of step catches has also become known, according to the preamble of independent claim 1, in which the lower fastening element has two angles and the upper fastening element consists of two angles with rotary openings, the elastic articulation ends of the carrier having outwardly projecting bearing journals (EP-A-0 291 840).

Dem gegenüber liegt der vorliegenden Erfindung die Aufgabe zugrunde, nicht nur die Stabilität eines Kopf- und Fußstellers der eingangs geschilderten Art zu verbessern, sondern darüber hinaus auch die Sicherheit und die Steifigkeit seiner Anlendungen die den Matratzenrahmen bzw. den beweglichen Rahmenteil bei knappstem Materialeinsatz zu verbessern.In contrast, the object of the present invention is not only to improve the stability of a head and foot plate of the type described above, but also to improve the safety and rigidity of its fittings which improve the mattress frame or the movable frame part with the scarcest use of materials .

Es wurde gefunden, daß sich dieses in einfacher Weise dadurch lösen läßt, daß das untere Befestigungselement ein zwischen den zwei Winkeln angeordnetes flaches Schwenkstück und die Schenkel des Anlenkendes der U-förmigen Zahnschiene mit einem Schlitz versehene Anlenköffnungen einschließen, daß die Anlenkstreben des Trägers L-förmig nach innen umgebogene obere Versteifungskanten und die Winkel des oberen Anschlußelementes Schlupfkanäle zu den Drehöffnungen für die nach außen ragenden Lagerzapfen an den Anlenkenden des Trägers aufweisen, und daß der Schieber innerhalb der U-förmigen Zahnschiene in Längssicken geführt ist, die zugleich Versteifungssicken für die Zahnschiene sind.It has been found that this can be solved in a simple manner in that the lower fastening element includes a flat pivot piece arranged between the two angles and the legs of the articulation end of the U-shaped toothed rail include articulated openings provided with a slot, such that the articulation struts of the carrier L- shaped inwardly bent upper stiffening edges and the angles of the upper connecting element slip channels to the rotary openings for the outwardly projecting bearing pins on the pivot ends of the carrier, and that the slide is guided within the U-shaped toothed rail in longitudinal beads, which at the same time stiffening beads for the toothed rail are.

Die Zahnschiene und der Träger der Kopf- bzw. Fußsteller nach der Erfindung sind in sich bei relativ dünnem Blech in jeder Richtung belastungssteif. Darüber hinaus hält das erfindungsgemäß ausgebildete untere Befestigungselement hohe Dauerbelastung aus. Das flache Schwenkstück ist sicher zwischen den beiden Winkeln des Befestigungselementes angebracht, die ihrerseits fest mit dem Rahmen verbunden sind. Um eine einfache Verbindung der Zahnschiene mit dem Schwenkstück zu ermöglichen, weisen die Anlenköffnungen der Zahnschiene Schlitze auf, die so gerichtet sind, daß die Zahnschiene bequem auf ihr unteres Befestigungselement aufgesteckt werden kann.The toothed rail and the support of the head or foot plate according to the invention are inherently load-resistant in any direction with relatively thin sheet metal. In addition, the lower fastening element designed according to the invention withstands high permanent loads. The flat swivel is securely attached between the two angles of the fastener, which in turn are firmly connected to the frame. In order to enable a simple connection of the toothed splint to the swivel piece, the articulation openings of the toothed splint have slots which are directed in such a way that the toothed splint can be easily plugged onto its lower fastening element.

Die bisher störende Seitenstabilität der Anlenkstreben des Trägers wird sicher dadurch verhindert, daß deren obere Kanten L-förmig nach innen umgebogene Versteifungskanten aufweisen. Diese erhöhen die Steifigkeit des Trägers beträchtlich. Um gleichwohl die Anlenkenden der so ausgebildeten Anlenkstreben mit den Winkeln des oberen Anschlußelementes verbinden zu können, sind in diesen Schlupfkanäle zu den Drehöffnungen vorgesehen, durch die die Lagerzapfen an den Trägern geschoben werden. Hierbei brauchen die Anlenkstreben des Trägers nicht von Hand aufeinander zugeschoben werden, was eine Arbeitserleichterung bedeutet. Das Einführen der Lagerzapfen durch die Schlupfkanäle läßt sich einfach und ohne besonderen Fingerkraftaufwand bewerkstelligen. Die Schlupfkanäle können auch außen und die Lagerzapfen innen angeordnet sein.The previously disruptive lateral stability of the hinge struts of the carrier is certainly prevented by the fact that their upper edges have an L-shaped stiffening edges bent inwards. These significantly increase the stiffness of the wearer. In order nevertheless to connect the articulation ends of the articulation struts thus formed to the angles of the upper connection element can be provided in these slip channels to the rotary openings through which the bearing pins are pushed on the carriers. In this case, the support struts do not have to be pushed towards one another by hand, which makes work easier. The insertion of the bearing journals through the slip channels can be accomplished easily and without any special effort. The slip channels can also be arranged outside and the bearing journals inside.

In weiterer Ausbildung der Erfindung ist der Schieber als Steuerelement zur rastfreien Rückführung innerhalb der U-förmigen Zahnschiene angeordnet. Er wird dabei in nach außen weisende Längssicken geführt, die zugleich Versteifungssicken für die Zahnschiene sind.In a further embodiment of the invention, the slide is arranged as a control element for restless return within the U-shaped toothed rail. It is guided in longitudinal beads that point outwards, which are also stiffening beads for the toothed rail.

Durch das Zusammenwirken der im Anspruch 1 gekennzeichneten Merkmale ergeben sich sowohl hinsichtlich des Materialverbrauches bei der Herstellung der Kopf- bzw. Fußsteller als auch hinsichtlich der Stabilität seiner Anlenkungen an die Rahmenteile besondere Vorteile. Es wird in einfacher Weise die Fließbandherstellungsmöglichkeit für die Rahmen bzw. Rahmenteile verbessert und zugleich das Zusammenfügen der Rahmenteile mit den Kopf- oder Fußstellern nach der Fertigstellung der Rahmen erleichtert. Zugleich ergibt sich ein besonderer Vorteil dadurch, daß die Verbindungen zwischen den Zahnschienen bzw. den Trägern und den neuen Befestigungselementen eine große Dauerstandfestigkeit bei geringer Abnutzung aufweisen. Im Bedarfsfall lassen sich die Teile des Kopf- oder Fußstellers auch leicht wieder von den Befestigungselementen demontieren.The interaction of the features characterized in claim 1 results in particular advantages both in terms of the material consumption in the manufacture of the head or foot plates and in terms of the stability of its articulations on the frame parts. The assembly line production facility for the frames or frame parts is improved in a simple manner and, at the same time, the assembly of the frame parts with the head or foot plates is made easier after the completion of the frames. At the same time, there is a particular advantage in that the connections between the toothed rails or the supports and the new fastening elements have a high fatigue strength with little wear. If necessary, the parts of the head or foot plate can also be easily removed from the fasteners.

Weitere Merkmale und Einzelheiten der Erfindung ergeben sich aus den Unteransprüchen 2 bis 6.Further features and details of the invention emerge from subclaims 2 to 6.

Durch die Ausbildung der Zahnschiene gemäß Anspruch 2 in Verbindung mit den in ihren Schenkeln angeordneten Längssicken wird eine außerordentliche Steifigkeit der Zahnschienen sichergestellt. Diese Steifigkeit wird noch durch die im Anspruch 5 gekennzeichneten Maßnahmen erhöht.The design of the toothed rail according to claim 2 in conjunction with the longitudinal beads arranged in its legs ensures an extraordinary rigidity of the toothed rails. This rigidity is increased by the measures characterized in claim 5.

Gleiches gilt für die Maßnahmen gemäß Anspruch 6 für die Ausbildung des Trägers.The same applies to the measures according to claim 6 for the training of the carrier.

Die jeweils mit Winkeln versehenen oberen und unteren Befestigungselemente können mittels Einloch-, Mehrloch- bzw. U-Profile am Rahmen bzw. an den Rahmenteilen befestigt werden, unabhängig davon, ob Rahmen- bzw. Rahmenteile aus Holz oder Metallrohren verwendet werden.The upper and lower fastening elements, each provided with angles, can be fastened to the frame or to the frame parts by means of single-hole, multi-hole or U profiles, regardless of whether frame or frame parts made of wood or metal tubes are used.

Durch die im Anspruch 4 gekennzeichenten Maßnahmen wird am Ende des Verformungsprozesses bei der Herstellung des Trägers eine Anpassung an die Form-Zahnschiene erreicht.Due to the measures characterized in claim 4, an adaptation to the shaped toothed splint is achieved at the end of the deformation process in the manufacture of the carrier.

The carrier 43 consists of a substantially U-shaped part 44 to which two articulation struts 46 and 50 are connected. Each articulation strut 46 or 50 has an inwardly bent stiffening edge 47 or 51. The articulation struts 46 and 50 end in articulation ends 48 and 52, each with a bearing journal 49 and 53. Stiffening beads 54 are provided in the articulation struts 46 and 50, and a stiffening bead 55 is provided in the bottom of the U-shaped part of the carrier.

Zwischen der Zahnschiene 6 und dem Träger 43 ist eine Stützstrebe 57 mit einem Rastende 58 vorgesehen, welches mit einem Schieber 59 in Wirkverbindung steht. Das Rastende 58 der Stützstrebe 57 rastet in den Raststellungen des Kopf- oder Fußstellers in den entsprechenden Rastzähnen 9 und 16 ein. Der Schieber 59 ist in an sich bekannter Weise so ausgebildet, daß beim Rückführen des Kopf- oder Fußstellers in seiner Ruhelage eine freie Bewegung des Rastendes 58 oberhalb der Rastzähne 9 und 16 erfolgen können. Der Schieber 59 wird von den oberen Längskanten 8 und 15 umschlossen. Der Schieber 59 ist, wie dieses vor allem die Fig. 1 c) erkennen läßt, auch in den Versteifungssicken 13 und 20 der Zahnschiene 6 geführt, die dieser eine zusätzliche Versteifung geben.A support strut 57 with a latching end 58 is provided between the toothed rail 6 and the carrier 43 and is operatively connected to a slide 59. The latching end 58 of the support strut 57 snaps into the corresponding latching teeth 9 and 16 in the latched positions of the head or foot plate. The slider 59 is designed in a manner known per se so that when the head or foot actuator is returned in its rest position, the detent end 58 can move freely above the detent teeth 9 and 16. The slide 59 is enclosed by the upper longitudinal edges 8 and 15. The slider 59, as can be seen above all from FIG. 1 c), is also guided in the stiffening beads 13 and 20 of the toothed rail 6, which give it additional stiffening.

Die Fig. 4 a) bis f) zeigen verschiedene Ausbildungsformen von unteren Befestigungselementen 27 für die Zahnschiene 6 am Matratzenrahmen 4 bzw. 5. Das untere Befestigungselement 27 besteht in seiner Grundstruktur aus zwei Winkeln 28 und 29, die durch ein flaches Schwenkstück 30 miteinander verbunden sind. Die Fig. 4 c) bis f) zeigen, wie diese Grundstruktur des unteren Befestigungselementes 27 an den Matratzenrahmen 4 bzw. 5 befestigt werden kann. Dieses kann im einfachsten Fall durch ein Zweilochprofil 31 erfolgen, an welchem die beiden Winkel 28 bzw. 29 befestigt sind.4 a) to f) show different designs of lower fastening elements 27 for the toothed splint 6 on the mattress frame 4 and 5. The lower fastening element 27 consists in its basic structure of two angles 28 and 29 which are connected to one another by a flat swivel piece 30 are. 4 c) to f) show how this basic structure of the lower fastening element 27 can be fastened to the mattress frame 4 or 5. In the simplest case, this can be done by a two-hole profile 31, to which the two angles 28 and 29 are attached.

Die Befestigung der Winkel 28 bzw. 29 am Matratzenrahmen 4 bzw. 5 kann auch durch Mehrlochprofile 32 erfolgen.The angles 28 and 29 can also be fastened to the mattress frame 4 and 5 by multi-hole profiles 32.

Ohne am Kern der Erfindung etwas zu ändern, sind auch andere Befestigungsarten der unteren Befestigungselemente 27 am Matratzenrahmen 4 bzw. 5 möglich. Gemäß Fig. 4 c) werden die Winkel 28 bzw. 29 mittels nicht bezeichneter Abwinklungen am Metall-Matratzenrahmen 5 angeklebt, angelötet oder angeschweißt. In den Fällen, in denen die unteren Befestigungselemente 7 mit Holzrahmen 4 zu verbinden sind, werden Schraubverbindungen bevorzugt.Without changing anything at the core of the invention, other types of fastening of the lower fastening elements 27 on the mattress frame 4 or 5 are also possible. According to Fig. 4 c), the angles 28 and 29 are glued, soldered or welded to the metal mattress frame 5 by means of bends not shown. In the cases in which the lower fastening elements 7 are to be connected to wooden frames 4, screw connections are preferred.

Fig. 5 a) bis f) zeigen Ausführungsbeispiele von oberen Befestigungselementen 35, die ebenfalls aus Winkeln 36 und 37 bestehen, in welchen Drehöffnungen 38 vorgesehen sind. Wesentlich ist, daß bei hinreichender Steifigkeit der oberen Befestigungselemente 35 zu den Drehöffnungen 38 hin Schlupfkanäle 39 führen, durch welche sich die Lagerzapfen 49 und 53 an den Anlenkenden 48 und 52 der Anlenkstreben 46 und 50 hindurchbewegen. Diese Schlupfkanäle 39 erleichtern das Verbinden des Trägers mit dem jeweils zugehörigen oberen Befestigungselement 35, zumal die Anlenkstreben 46 und 50 durch ihre nach innen umgebogenen Versteifungskanten 47 und 51 eine nicht unbeträchtliche Eigensteifigkeit aufweisen.Ohne am Kern der Erfindung etwas zu ändern, können die Schlupfkanäle 39 auch von "außen" nach "innen" verlaufen.5 a) to f) show exemplary embodiments of upper fastening elements 35, which likewise consist of angles 36 and 37, in which rotary openings 38 are provided. It is essential that, with sufficient rigidity of the upper fastening elements 35, slip channels 39 lead to the rotary openings 38, through which the bearing pins 49 and 53 on the articulation ends 48 and 52 of the articulation struts 46 and 50 move. These slip channels 39 make it easier to connect the carrier to the associated upper fastening element 35, especially since the articulation struts 46 and 50 have a not inconsiderable inherent rigidity due to their inwardly bent stiffening edges 47 and 51. Without changing the essence of the invention, the slip channels 39 can also run from "outside" to "inside".

Die oberen Befestigungselemente 35 mit ihren Winkeln 36 und 37 können vermittels Einlochprofilen 40 (Fig. 5 d), Fig. 5 e)) Mehrlochprofilen 41 (Fig. 5 b) und Fig. 5 f)) sowie U-Profilen 42 (Fig. 5 c) und 5 d)) an einem verschwenkbaren Rahmenteil 2 bzw. 3 angelenkt werden.The upper fastening elements 35 with their angles 36 and 37 can be made using single-hole profiles 40 (FIG. 5 d), FIG. 5 e)) multi-hole profiles 41 (FIG. 5 b) and FIG. 5 f)) and U-profiles 42 (FIG. 5 c) and 5 d)) are hinged to a pivotable frame part 2 or 3.

Die Fig. 1 und 3 lassen erkennen, daß das Gelenkende 45 des Trägers 43 zum Schwenkgelenk 56 hin auf das Gelenkende 25 der Zahnschiene 6 zu umgebogen ist. Dieses erfolgt am Schluß der Herstellungsarbeitsgänge des Trägers, dessen Grundkontur zunächst aus einer Platine ausgestanzt und dann schrittweise zu seiner in Fig. 3 b) strichpunktiert dargestellten Form gebogen wird, Erst wenn die Verformung bis dahin beendet ist, wird in einem letzten Arbeitsgang das Gelenkende 45 gemäß Fig. 3 b) "nach unten" gebogen. Im Arbeitsgang der Herstellung des Trägers 43 werden auch seine Anlenkstreben 46 und 50 - wie dieses die Fig. 3 a) zeigt - in die strichpunktierte Stellung nach außen gebogen, um im oberen Befestigungselement 35 eine genügend große Vorspannung zu haben.1 and 3 show that the hinge end 45 of the carrier 43 is bent towards the swivel joint 56 towards the hinge end 25 of the toothed splint 6. This takes place at the end of the manufacturing operations of the carrier, the basic contour of which is first punched out of a blank and then bent step by step to the shape shown in dash-dotted lines in FIG. 3 b). Only when the deformation has ended by then is the hinge end 45 in a last operation 3 b) "after In the process of producing the carrier 43, its articulation struts 46 and 50 - as shown in FIG. 3 a) - are also bent outwards into the dot-dash position in order to have a sufficiently large prestress in the upper fastening element 35.

Mit der Erfindung ist es möglich, die Kopf- bzw. Fußsteller 1 nach Fertigstellung des Rahmens in die an diesem angebrachten unteren Befestigungselementen 27 und oberen Befestigungselementen 36 einzufügen. Hierbei werden die Schlitze 12 und 19 in den Anlenköffnungen 11 und 18 auf die flachen Schwenkstücke 30 der unteren Befestigungselemente 27 gesteckt. Diese Schwenkverbindung zwischen den unteren Befestigungselementen 27 und der Zahnschiene 6 ist wegen der Winkel 36 und 37 und ihrer Befestigung am Matratzenrahmen auch bei Dauerbelastung sicher. Die Richtung der Schlitze 12 und 19 ist dabei so gewählt, daß bei der normalen Lagen der Zahnschiene ein Auseinanderfallen dieser Steckverbindungen unmöglich ist.With the invention it is possible to insert the head or foot plate 1 into the lower fastening elements 27 and upper fastening elements 36 attached to the frame after completion of the frame. Here, the slots 12 and 19 are inserted in the articulation openings 11 and 18 on the flat pivot pieces 30 of the lower fastening elements 27. This swivel connection between the lower fastening elements 27 and the toothed rail 6 is secure because of the angles 36 and 37 and their fastening to the mattress frame even under permanent load. The direction of the slots 12 and 19 is chosen so that in the normal position of the toothed rail a falling apart of these connectors is impossible.

Ebenso sicher ist die Steckverbindung zwischen den Lagerzapfen 49 und 51 an den Anlenkenden 48 und 52 der Anlenkstreben 46 und 50 des Trägers 43. Ohne die Versteifungskanten 47 und 51 würde zwar die manuelle Handhabung beim Einführen der Lagerzapfen 49 und 53 in die Drehöffnungen 38 der oberen Befestigungselemente 35 einfacher sein, jedoch würde darunter die Steifigkeit der Kopf- oder Fußsteller 1 erheblich leiden. Durch die Schlupfkanäle 39 zu den Drehöffnungen wird bei beträchtlicher Steifigkeit des Trägers 43 infolge der Versteifungskanten 47 und 51 eine einfache Verbindung des Träger mit seinem oberen Befestigungselement 35 ermöglicht.The plug connection between the bearing pins 49 and 51 at the articulation ends 48 and 52 of the articulation struts 46 and 50 of the carrier 43 is just as secure. Without the stiffening edges 47 and 51, the manual handling when inserting the bearing pins 49 and 53 into the rotary openings 38 of the upper would Fastening elements 35 would be simpler, however, the rigidity of the head or foot plate 1 would suffer considerably. The slip channels 39 to the rotary openings enable the carrier to be easily connected to its upper fastening element 35 with considerable rigidity of the carrier 43 as a result of the stiffening edges 47 and 51.
