Description

Die Erfindung betrifft eine Liegefläche mit einem Arretierelement nach dem Oberbegriff des Patentanspruches 1.The invention relates to a lying surface with a locking element according to the preamble of claim 1.

Der Begriff "Liegefläche" meint Lattenroste, die aus mindestens einem Mittelteil und einem daran schwenkbar angeordneten Kopfteil bestehen.The term "lying surface" means slatted frames, which consist of at least one central part and a head portion pivotally mounted thereto.

Darüber hinaus bezieht sich die Erfindung auch auf Liegeflächen, die nicht mit Federleisten arbeiten, sondern mit punktförmig abstützenden Elastikelementen, die auch gepolstert und bespannt sein können, wobei jedoch auch für diese Art von Liegeflächen kennzeichnend ist, dass sie aus mindestens einem Mittelteil und einem schwenkbar damit verbundenen Kopfteil bestehen.In addition, the invention also relates to lying surfaces that do not work with slats, but with punctiform supporting elastic elements that can be padded and covered, but also for this type of lying surfaces is characteristic that they consist of at least one central part and a swivel consist connected headboard.

In anderen Ausführungsformen sieht die Erfindung vor, dass die Liegefläche aus insgesamt drei Teilen besteht, nämlich einem Mittelteil und einem schwenkbar daran angeordneten Kopfteil und einem Fußteil, welches ebenfalls am Mittelteil schwenkbar befestigt ist.In other embodiments, the invention provides that the lying surface consists of a total of three parts, namely a central part and a pivotally arranged thereon head part and a foot part, which is also pivotally mounted on the central part.

Darüber hinaus sieht die Erfindung auch Liegeflächen vor, bei denen das Kopfteil in zwei zueinander abwinkelbare und schwenkbar zueinander gelagerte Kopfteilbereiche unterteilt ist. Die beiden Kopfteilbereiche sind demnach mittels eines geeigneten Hubantriebes gegeneinander verschwenkbar ausgebildet.In addition, the invention also provides lying surfaces, in which the head part is divided into two mutually bendable and pivotally mounted to each other headboard areas. The two head portions are therefore formed by means of a suitable lifting drive against each other pivotable.

Bei derartigen Liegeflächen, bei denen mindestens an einem Mittelteil ein Kopfteil schwenkbar befestigt ist, gibt es das Problem der Schwenkwinkelbegrenzung. Das Kopfteil soll in einer abgesenkten Stellung bezüglich des Mittelteils eine durchgehende fluchtende Ebene bilden, und es soll auf jeden Fall vermieden werden, dass die Ebene des Mittelteils unter diese Ebene herunter geschwenkt wird.In such lying surfaces, in which at least at one central part a head part is pivotally mounted, there is the problem of Schwenkwinkelbegrenzung. The head part is to form a continuous aligned plane in a lowered position with respect to the central part, and it should be avoided in any case that the plane of the central part is pivoted down below this level.

Die DE 100 18 567 C2 zeigt einen Lattenrost, wobei jeweils das Fuß- und das Kopfteil über jeweils ein Gelenkteil mit dem Mittelteil verbunden sind. Das Gelenkteil weist zwei Gelenkglieder auf, wobei das erste Gelenkglied eine Gelenkverbindung zu dem Kopf-bzw. Fußteil ermöglicht und das zweite Gelenkglied eine Gelenkverbindung zum Mittelteil. Das Gelenkteil weist zudem eine zu den jeweiligen Gelenkachsen senkrechte Deckplatte mit schrägen Anschlagflächen auf, welche sich je nach Lage der einzelnen Teile an korrespondierende Gegenanschlagflächen an dem Mittelteil oder an dem Kopf-bzw. Fußteil anlegen. Die Anschlagflächen dienen zur Begrenzung des Schwenkwinkels der Holmteile relativ zum Gelenkteil.The DE 100 18 567 C2 shows a slatted frame, wherein each of the foot and the head part are connected via a respective hinge part with the central part. The Joint part has two joint members, wherein the first joint member has a hinge connection to the head or. Foot allows and the second hinge member a hinge connection to the middle part. The hinge part also has a vertical to the respective hinge axes cover plate with oblique stop surfaces, which depending on the position of the individual parts of corresponding counter-stop surfaces on the central part or on the head or. Create foot part. The stop surfaces serve to limit the pivot angle of the spar parts relative to the joint part.

Nachteilig an dieser Vorrichtung ist, dass das Gelenkteil über zwei Gelenkachsen verfügt und neben den Anschlagflächen des Gelenkteils noch weitere Fixierungselemente, wie z.B. Bolzen benötigt werden, um die einzelnen Teile in einem bestimmten Schwenkwinkel zu arretieren.A disadvantage of this device is that the joint part has two joint axes and in addition to the abutment surfaces of the joint part further fixing elements, such. Bolts are needed to lock the individual parts in a certain swing angle.

Bei elektromotorisch angetriebenen Schwenkantrieben für Liegeflächen besteht das weitere Problem, dass bei mehrfach abgewinkelten Teilbereichen der Liegefläche der Hubantrieb in eine Stellung kommen kann, wo eine Selbsthemmung stattfindet. Eine solche Selbsthemmung beim Betrieb der Hubantriebe soll auf jeden Fall verhindert werden.In electric motor-driven rotary actuators for lying surfaces, there is the further problem that in multi-angled portions of the bed surface of the lifting drive can come into a position where a self-locking takes place. Such self-locking during operation of the linear actuators should be prevented in any case.

Der Erfindung liegt deshalb die Aufgabe zugrunde, eine Liegefläche der eingangs genannten Art so auszubilden, dass durch ein Arretierelement eine Schwenkwinkelbegrenzung für die schwenkbar mit dem Mittelteil verbundenen Liegeflächebereichen vorgesehen werden kann.The invention is therefore based on the object, a lying surface of the type mentioned in such a way that by a locking element a pivot angle limit for the pivotally connected to the middle part lying surface areas can be provided.

Zur Lösung der gestellten Aufgabe ist die Erfindung durch die technische Lehre des Anspruches 1 gekennzeichnet.To solve the problem, the invention is characterized by the technical teaching of claim 1.

Bei der erfindungsgemäßen Liegefläche wird das Arretierelement zur Schwenkwinkelbegrenzung zwischen den beiden abwinkelbaren Kopfteilbereichen verwendet.In the lying surface according to the invention the locking element is used for pivoting angle limitation between the two bendable headboard areas.

Es ist vorteilhaft, ein solches Arretierelement bei einer solchen Liegefläche einzusetzen und die Schwenkwinkelbegrenzung zwischen den beiden voneinander abwinkelbaren Kopfteilbereichen im Bereich der Schwenkachse vorzusehen.It is advantageous to use such a locking element in such a lying surface and to provide the pivoting angle limit between the two mutually bendable head portions in the region of the pivot axis.

Bei solchen getrennt voneinander abwinkelbaren Kopfteilbereichen besteht nämlich das Problem, dass der obere Kopfteilbereich beim Schwenkantrieb mittels einer Hubstange unbeabsichtigt nach unten umschlägt und der Hubantrieb dann nicht mehr in der Lage ist, diesen Kopfteilbereich wieder aufzurichten und in einer Ebene mit dem anderen Kopfteilbereich zu bringen, der nächst dem Mittelteil angeordnet ist. Der Schwenkantrieb kann hydraulisch, pneumatisch oder elektromotorisch arbeiten. Insbesondere können auch Gasdruckfedern als Schwenkantrieb verwendet werden.In fact, in the case of such separately bendable head part regions, there is the problem that the upper head part region unintentionally pivots downwards during the pivoting drive by means of a lifting rod and the lifting drive is then no longer able to erect this head part region again and bring it in one plane with the other head part region. the next to the middle part is arranged. The rotary actuator can work hydraulically, pneumatically or by electric motor. In particular, gas springs can be used as a rotary actuator.

Zu diesem Zweck sieht die Erfindung vor, dass in diesem Bereich die Schwenkwinkelbegrenzung mit dem Arretierelement angeordnet wird. Eine nicht erwünschte Selbsthemmung bei einem solchen Hubantrieb mit zueinander abwinkelbaren Kopfteilbereichen besteht in der Regel aus einer Hubstange, die etwa parallel zur Längsachse der beiden schwenkbar miteinander verbundenen Längsholme verläuft, wenn sich diese in einer durchgehenden, gestreckten Lage befinden.For this purpose, the invention provides that in this area the pivoting angle limit is arranged with the locking element. An undesirable self-locking in such a lifting drive with mutually angled headboard areas usually consists of a lifting rod, which runs approximately parallel to the longitudinal axis of the two pivotally interconnected longitudinal beams, if they are in a continuous, extended position.

Aufgrund von mechanischen Ungenauigkeiten oder Spiel in den Lagerelementen kann es jedoch vorkommen, dass der obere Kopfteilbereich unter die Ebene des daran anschließenden anderen Kopfteilbereiches umschlägt und zu diesem Zweck ist das erfindungsgemäße Arretierelement vorgesehen, welches in den Schwenkbereich der beiden verbundenen Kopfteilbereiche so eingesteckt wird, dass ein unerwünschtes Umschlagen des oberen Kopfteilbereiches nach unten vermieden wird.However, due to mechanical inaccuracies or play in the bearing elements, it may happen that the upper head portion below the level of the adjoining other head portion and for this purpose the locking element according to the invention is provided, which is plugged into the pivot region of the two connected head portions so that avoiding unwanted turning of the upper head portion down.

Der Erfindungsgegenstand der vorliegenden Erfindung ergibt sich nicht nur aus dem Gegenstand der einzelnen Patentansprüche, sondern auch aus der Kombination der einzelnen Patentansprüche untereinander, wie es in den Ansprüchen definiert ist. Alle in den Unterlagen, einschließlich der Zusammenfassung offenbarten Angaben und Merkmale, insbesondere die in den Zeichnungen dargestellte räumliche Ausbildung, werden als erfindungswesentlich beansprucht, soweit sie einzeln oder in Kombination gegenüber dem Stand der Technik neu sind.The subject of the present invention results not only from the subject matter of the individual claims, but also from the combination of the individual claims with each other, as defined in the claims.

In Figur 1 und Figur 2 ist allgemein ein Bettrahmen 1 dargestellt, auf dem eine Liegefläche 3 in der Art eines Lattenrostes aufgelegt ist. Der Bettrahmen 1 ist mit Stützfüßen 2 gegenüber einer Aufstellebene abgestützt.In FIG. 1 and FIG. 2 a bed frame 1 is generally shown, on which a lying surface 3 is placed in the manner of a slatted frame. The bed frame 1 is supported with support feet 2 against a mounting plane.

Die Liegefläche 3 ist als Lattenrost ausgebildet, wobei der Lattenrost aus einer Vielzahl von parallel nebeneinander liegenden Lamellen besteht, die in zugeordneten Stützkörpern 37 aufgenommen sind, die ihrerseits federnd gegenüber den Längsholmen 21, 22 gelagert sind.The lying surface 3 is formed as a slatted frame, wherein the slatted frame consists of a plurality of parallel adjacent slats, which are received in associated support members 37, which in turn are resiliently mounted with respect to the longitudinal bars 21, 22.

Der Lattenrost 4 besteht in einer bevorzugten Ausgestaltung aus einem Mittelteil 5, an dem ein Kopfteil 7 über eine erste Schwenkachse 9 ansetzt, welches aus zwei zueinander abwinkelbaren Kopfteilbereichen 7a, 7b besteht.The slatted frame 4 consists in a preferred embodiment of a central part 5, to which a head part 7 attaches via a first pivot axis 9, which consists of two mutually angled head portions 7a, 7b.

Die abwinkelbaren Kopfteilbereiche 7a, 7b sind durch eine horizontale Schwenkachse 8 schwenkbar miteinander verbunden.The bendable head portions 7a, 7b are pivotally connected to each other by a horizontal pivot axis 8.

An der gegenüberliegenden Seite des Mittelteils 5 setzt ein Fußteil 6 über eine weitere horizontale Schwenkachse 10 an.On the opposite side of the middle part 5, a foot part 6 sets via a further horizontal pivot axis 10.

Die Erfindung ist nicht auf ein in sich abgewinkeltes Kopfteil 7 mit den zwei zueinander schwenkbar ausgebildeten Kopfteilbereichen 7a, 7b beschränkt. Es kann auch ein einziges, durchgehendes Kopfteil 7 verwendet werden.The invention is not limited to an angled head portion 7 with the two mutually pivotally shaped head portions 7a, 7b. It is also possible to use a single, continuous head part 7.

Im gezeigten Ausführungsbeispiel ist der Lattenrost 4 über mehrere Hubantriebe schwenkbar ausgebildet.In the illustrated embodiment, the slatted base 4 is designed to be pivotable via a plurality of lifting drives.

Über einen Hubantrieb 13 kann die Schwenklage des Fußteils 6 eingestellt und festgestellt werden. Über den Hubantrieb 12 kann die Schwenklage des unteren Kopfteilbereiches 7b eingestellt werden, und durch den Hubantrieb 14 kann die Schwenklage des oberen Kopfteilbereichs 7a im Vergleich zu dem unteren Kopfteilbereich 7b einstellbar gestaltet sein.About a lifting drive 13, the pivotal position of the foot part 6 can be adjusted and determined. Via the lifting drive 12, the pivotal position of the lower head portion 7b can be adjusted, and by the lifting drive 14, the pivotal position of the upper head portion 7a compared to the lower head portion 7b be designed adjustable.

Zu diesem Zweck wirkt die Hubstange 15 des Hubantriebes 12 auf ein erstes Drehlager, welches an der Unterseite des Kopfteils 7b angeordnet ist. Die Hubstange 16 des zweiten Hubantriebes 14 wirkt über eine Drehachse 17 auf einen Halter 18, der an der Unterseite des Kopfteilbereiches 7a befestigt ist.For this purpose, the lifting rod 15 of the lifting drive 12 acts on a first pivot bearing, which is arranged on the underside of the head part 7b. The lifting rod 16 of the second lifting drive 14 acts via a rotation axis 17 on a holder 18 which is fixed to the underside of the head portion 7a.

Erfindungsgemäß ist in einer bevorzugten Ausgestaltung ein Arretierelement 20 im Schwenkbereich zwischen den beiden Kopfteilbereichen 7a, 7b angeordnet, um gemäß Figur 2 zu vermeiden, dass der obere Kopfteilbereich 7a in Pfeilrichtung 19 nach unten fällt und hierbei die Hubstange 16 des Hubantriebes 14 in eine Selbsthemmung kommt, so dass die unbeabsichtigte Schwenklage des Kopfteilbereiches 7a in Pfeilrichtung 19 nicht mehr ohne fremde Krafteinwirkung aufzuheben ist. Zu diesem Zweck sieht die Erfindung vor, dass ein Arretierelement 20 im Schwenkbereich zwischen den beiden schwenkbar miteinander verbundenen Kopfteilbereichen 7a, 7b angeordnet ist, welche die gestreckte Stellung der Längsholme in Richtung nach unten begrenzt..According to the invention, in a preferred embodiment, a locking element 20 is arranged in the pivoting area between the two head part regions 7a, 7b in order to move according to FIG FIG. 2 to avoid that the upper head portion 7a falls down in the direction of arrow 19 and in this case the lifting rod 16 of the lifting drive 14 comes in a self-locking, so that the unintentional pivotal position of the head portion 7a in the direction of arrow 19 is no longer able to be lifted without external force. To this end, the invention provides that a locking element 20 is arranged in the pivoting area between the two pivotally interconnected head portions 7a, 7b, which limits the extended position of the longitudinal bars in the downward direction.

Hierauf ist die Erfindung nicht beschränkt. In einer anderen Ausgestaltung kann es vorgesehen sein, dass das Arretierelement 20 im Bereich der Schwenkachse 9 und/oder im Bereich der Schwenkachse 10 angeordnet ist.The invention is not limited thereto. In another embodiment, it can be provided that the locking element 20 is arranged in the region of the pivot axis 9 and / or in the region of the pivot axis 10.

Die Erfindung betrifft somit die Anordnung eines Arretierelementes 20 im Bereich der jeweiligen Schwenkachsen 8, 9, 10.The invention thus relates to the arrangement of a locking element 20 in the region of the respective pivot axes 8, 9, 10th

Das Arretierelement 20 wird jeweils links und rechts der Längsholme im Bereich der jeweiligen Schwenkachse 8-10 angebracht. Es ist somit immer paarweise im Bereich einer Schwenkachse vorhanden.The locking element 20 is respectively attached to the left and right of the longitudinal beams in the region of the respective pivot axis 8-10. It is thus always available in pairs in the range of a pivot axis.

Anstatt der paarweisen Anordnung kann es in einer anderen Anordnung vorgesehen sein, das Arretierelement 20 nur an einer Seite anzubringen. Wenn in der folgenden Beschreibung eine paarweise Anordnung beschrieben ist, so ist dies nicht einschränkend zu verstehen.Instead of the paired arrangement, it may be provided in another arrangement to attach the locking member 20 only on one side. When a paired arrangement is described in the following description, this is not meant to be limiting.

Die Figur 3 zeigt als Ausführungsbeispiel die Verwendung des Arretierelementes 20 im Bereich der Schwenkachse 8. Wie vorhin angegeben, kann jedoch auch die Schwenkachse 9 oder die Schwenkachse 10 mit einem derartigen Arretierelement 20 ausgerüstet sein, wobei jedes Arretierelement 20 paarweise vorhanden ist.The FIG. 3 shows as an example the use of the locking element 20 in the region of the pivot axis 8. As indicated above, however, the pivot axis 9 or the pivot axis 10 may be equipped with such a locking element 20, wherein each locking member 20 is present in pairs.

Im Ausführungsbeispiel ist dargestellt, dass der dem Kopfteilbereich 7b zugeordnete Längsholm 21 an seinem einen Ende ein Halteteil 23 aufweist, in welches das Arretierelement 20 formschlüssig eingesteckt werden kann.In the exemplary embodiment it is shown that the longitudinal member 21 assigned to the head part region 7b has a holding part 23 at one end, into which the locking element 20 can be inserted in a form-fitting manner.

Das Arretierelement 20 liegt dann gemäß der Figur 4 vor dem Halteteil 23 und bildet somit Anschlagflächen für die Schwenkwinkelbegrenzung des schwenkbar daran anschließenden Längsholm 22.The locking element 20 is then according to the FIG. 4 in front of the holding part 23 and thus forms stop surfaces for the pivoting angle limit of the pivotally adjoining longitudinal beam 22nd

Die Figur 6 zeigt weitere Einzelheiten der Steckbefestigung des Arretierelementes 20.The FIG. 6 shows further details of the plug-in fastening of the locking element 20th

Das Halteteil 23, welches an dem einen Ende des Längsholmes 21 angeordnet ist, besteht im Wesentlichen aus einem mehrfach verrippten Kunststoffteil, wobei ausgehend von einer zentrischen Durchgangsbohrung 27 eine Anzahl von Rippen 25 vorhanden sind, die zu den Wänden des Halteteils 23 gehen und ein werkstoffeinstückiges Kunststoffteil bilden.The holding part 23, which is arranged at one end of the longitudinal spar 21, consists essentially of a multiply ribbed plastic part, wherein starting from a central through-hole 27, a number of ribs 25 are present, which go to the walls of the holding part 23 and form a material integral plastic part.

Es ist eine Rippe 25 vorhanden, die zwischen sich zwei voneinander getrennte Aufnahmeräume 24, 26 im Halteteil 23 definiert.There is a rib 25 which defines between them two separate receiving spaces 24, 26 in the holding part 23.

Das Arretierelement 20 ist als Kunststoffteil ausgebildet und bildet einen Dreieckskörper 29, an dessen Innenseiten zwei durch einen Schlitz 23 voneinander getrennte Steckkörper 34, 35 angeformt sind. Jeder Steckkörper 34, 35 ist in seiner Formgebung so gestaltet, dass er formschlüssig in den zugeordnete Aufnahmeraum 24, 26 im Halteteil 23 eingesteckt werden kann.The locking element 20 is formed as a plastic part and forms a triangular body 29, on whose insides two through a slot 23 separate plug body 34, 35 are formed. Each plug body 34, 35 is designed in its shape so that it can be positively inserted into the associated receiving space 24, 26 in the holding part 23.

Somit liegt der Dreieckskörper 29 mit einer hinteren Anschlagfläche 30 an einer zugeordneten inneren Anschlagfläche 36 im Halteteil 23 an und bildet eine nach vorne gerichtete, hierzu abgewinkelte Anschlagfläche 31, die an die zugeordnete Anschlagfläche 32 des Längsholms 22 zur Anlage bringbar ist.Thus, the triangular body 29 abuts with a rear abutment surface 30 on an associated inner abutment surface 36 in the holding part 23 and forms a forwardly directed, angled stop surface 31 which can be brought to the associated stop surface 32 of the longitudinal beam 22 to the plant.

Im zusammengebauten Zustand ergibt sich somit die Situation nach den Figuren 4 und 5, wo erkennbar ist, dass die beiden Längsholme 21, 22 im gestreckten Zustand, wenn diese eine durchgehende Liegefläche in einer Ebene ergeben, zueinander anschlagbegrenzt sind.In the assembled state, the situation thus arises after the FIGS. 4 and 5 , where it can be seen that the two longitudinal beams 21, 22 in the extended state, when they result in a continuous lying surface in a plane, are stop-limited to one another.

Das Arretierelement verhindert ein Umschlagen des Längsholms 22 in Pfeilrichtung 19 gemäß Figur 5 unter die Ebene des Längsholmes 21.The locking element prevents a folding of the longitudinal spar 22 in the direction of arrow 19 according to FIG. 5 under the plane of the longitudinal spar 21st

Selbstverständlich kann der Winkel der Anschlagfläche 31 zu der Anschlagfläche 30 im Dreieckskörper 29 auch anders ausgebildet sein, um zu gewährleisten, dass der Längsholm 22 in Bezug zu den in einer horizontalen Ebene liegenden Längsholm 21 eine gewisse Winkelstellung einnimmt und beibehält.Of course, the angle of the abutment surface 31 to the abutment surface 30 in the triangular body 29 may also be designed differently to ensure that the longitudinal beam 22 occupies and maintains a certain angular position relative to the longitudinal beam 21 lying in a horizontal plane.
