Definitions
- the invention relates to a bed frame with a rigid frame having two parallel and spaced-apart frame bars and a thigh support pivotably connected to it, to which a footrest is articulated.
- Such a bed frame is in the DE 87 07 008 U1 disclosed.
- the footrest is connected to the thigh support by means of an angle lever, while this angle lever is connected to a drive via a coupling member.
- the footrest is brought into a desired angular position, but at most in a position raised parallel to the frame bars.
- the storage space formed below the footrest can only be used with difficulty, even when the footrest is raised to the maximum, due to the small access opening.
- this bed frame only meets the usage requirements to a limited extent.
- support tabs are hinged to the side bars, which support the footrest when pivoting back from a certain pivot position, for which purpose support bearings are attached to the inside of the frame bars with a sliding surface that slide along the support tabs when the footrest is pivoted in and out.
- the support straps are attached to the side rails in such a way that they basically perform uncontrolled movements, so that there is a risk that they will not slide into the position required for use, especially when the footrest is pivoted back into an extended position.
- the EP 0 364 394 A2 , the DE 698 22 568 T2 , the DE 20 2006 005 301 U1 as well as the DE 201 07 553 U1 each show and describe a bed frame, the footrest of which can be pivoted by a motor, for which purpose a support lever is connected to an electric motor, while the footrest is preferably supported on a roller or cylinder of the support lever.

Description
Die Erfindung betrifft einen Bettrost, mit einem, zwei parallel und abständig zueinander angeordnete Rahmenholme aufweisenden starren Rahmen sowie einer daran schwenkbar angeschlossenen Schenkelstütze, an der eine Fußstütze angelenkt ist.The invention relates to a bed frame with a rigid frame having two parallel and spaced-apart frame bars and a thigh support pivotably connected to it, to which a footrest is articulated.
Ein solcher Bettrahmen ist in der
Damit wird die Fußstütze, je nach Verschwenkung des Koppelgliedes in eine gewünschte Winkelstellung gebracht, maximal jedoch in eine zu den Rahmenholmen angehobene parallele Position.Thus, depending on the pivoting of the coupling member, the footrest is brought into a desired angular position, but at most in a position raised parallel to the frame bars.
In Funktion, wenn also der Bettrost in einen Bettkasten eingesetzt ist, ist der unterhalb der Fußstütze gebildete Stauraum auch bei maximal hochgestellter Fußstütze nur beschwerlich nutzbar aufgrund der geringen Zugriffsöffnung. Insoweit entspricht dieser Bettrost nur eingeschränkt den Nutzungswünschen.In operation, i.e. when the bed frame is inserted into a bed box, the storage space formed below the footrest can only be used with difficulty, even when the footrest is raised to the maximum, due to the small access opening. In this respect, this bed frame only meets the usage requirements to a limited extent.
In der
Zur Abstützung der Fußstütze sind an deren Seitenholmen Stützlaschen angelenkt, die die Fußstütze beim Zurückschwenken ab einer bestimmten Schwenkstellung abstützen, wozu innenseitig an den Rahmenholmen Stützlager befestigt sind mit einer Gleitfläche, der entlang die Stützlaschen sowohl beim Ein- wie auch beim Ausschwenken der Fußstütze gleiten.To support the footrest, support tabs are hinged to the side bars, which support the footrest when pivoting back from a certain pivot position, for which purpose support bearings are attached to the inside of the frame bars with a sliding surface that slide along the support tabs when the footrest is pivoted in and out.
Nachteilig bei dieser Konstruktion ist allerdings der erhebliche Fertigungsaufwand, der zu betreiben ist, um insbesondere die Stützlager herzustellen und zu montieren.The disadvantage of this construction, however, is the considerable manufacturing effort that has to be carried out in order to manufacture and assemble the support bearings in particular.
Überdies sind die Stützlaschen derart an den Seitenholmen befestigt, dass sie im Grunde unkontrollierte Bewegungen vollführen, sodass die Gefahr besteht, dass sie insbesondere beim Zurückschwenken der Fußstütze in eine gestreckte Position nicht in die für die Nutzung erforderliche Position gleiten.In addition, the support straps are attached to the side rails in such a way that they basically perform uncontrolled movements, so that there is a risk that they will not slide into the position required for use, especially when the footrest is pivoted back into an extended position.
Aus der
Die
Der Erfindung liegt die Aufgabe zu Grunde, einen Bettrost der gattungsgemäßen Art so weiter zu entwickeln, dass er einfacher und damit kostengünstiger herstellbar ist und seine Funktion sicherer wird.The invention is based on the object of further developing a bed frame of the generic type in such a way that it can be produced more easily and thus more cost-effectively and its function becomes more reliable.
Diese Aufgabe wird durch einen Bettrost gelöst, bei dem in dem der Fußstütze zugeordneten Bereich der Rahmenholme jeweils ein drehgehemmt verschwenkbarer Stützhebel befestigt ist, dessen freies Ende entgegen der Aufschwenkrichtung der Fußstütze lösbar daran gehalten und bei dem zur Drehhemmung des Stützhebels eine Reib- oder Silikonbremse im Anlenkbereich mit dem Rahmenholm am Stützhebel angeordnet ist.This object is achieved by a bed frame, in which in the area of the frame spars assigned to the footrest there is a rotation-inhibited pivotable support lever, the free end of which is detachably held against the pivoting direction of the footrest, and in which a friction or silicone brake is used to prevent the support lever from rotating Articulation area is arranged with the frame spar on the support lever.
Die zum Stand der Technik beschriebene unkontrollierte Bewegung des Stützhebels ist durch die drehgehemmte Lagerung am Rahmenholmen ausgeschlossen. D. h., nach Erreichen einer maximalen Verschwenkstellung der Fußstütze durch einen Antrieb, bei der der Stützhebel von der Fußstütze mitgeschleppt wird, und einem weiteren manuellen Verschwenken der Fußstütze, verbleibt der Stützhebel in seiner erreichten Position, sodass beim manuellen Zurückführen der Fußstütze der Stützhebel in der zuletzt eingenommenen Stellung wieder mit der Fußstütze in Eingriff kommt.The uncontrolled movement of the support lever described in the prior art is precluded by the rotation-inhibited mounting on the frame bars. That is, after reaching a maximum pivoting position of the footrest by a drive in which the support lever is dragged along by the footrest, and a further manual pivoting of the footrest, the support lever remains in its reached position, so that when the footrest is manually returned, the support lever comes into engagement with the footrest again in the last position assumed.
Entscheidend dabei ist, dass der Stützhebel entgegen der Aufschwenkrichtung der Fußstütze lösbar an der Fußstütze gehalten ist. Hierzu sind sowohl an der Fußstütze wie auch am Stützhebel entsprechende Korrespondenzmittel vorgesehen.The decisive factor here is that the support lever is releasably held on the footrest against the pivoting direction of the footrest. For this purpose, corresponding means of correspondence are provided both on the footrest and on the support lever.
Nach einer vorteilhaften Weiterbildung der Erfindung ist als fußstützseitiges Korrespondenzmittel eine Aufnahmegabel an dem entsprechenden Seitenholm der Fußstütze befestigt, die zum Stützhebel hin offen ist.According to an advantageous further development of the invention, as a correspondence means on the footrest side, a receiving fork is attached to the corresponding side rail of the footrest and is open towards the support lever.
Als Korrespondenzmittel des Stützhebels weist dieser an seinem freien Ende einen Zapfen auf, der in Funktion in die Gabelöffnung eintaucht. Dieses Prinzip ist selbstverständlich auch umkehrbar, d. h., dass dann der Stützhebel an seinem freien, der Fußstütze zugewandten Ende eine Gabelöffnung aufweist, in die dann ein Zapfen der Fußstütze eingreift. Um ein problemloses Eintauchen des Zapfens in die Gabelöffnung zu gewährleisten, sind an der Gabelöffnung Einlaufschrägen vorgesehen.As a correspondence means of the support lever, the latter has a pin at its free end which, when in use, dips into the fork opening. This principle is of course also reversible, i. This means that the support lever then has a fork opening at its free end facing the footrest, into which a pin of the footrest then engages. In order to ensure problem-free immersion of the pin into the fork opening, bevels are provided on the fork opening.
Im Übrigen ist die Gabelöffnung so ausgebildet, dass sie sich zur Öffnungsseite hin verjüngt unter Ausbildung eines flachen Hinterschnitts. Dadurch ist gewährleistet, dass beim Anheben der Fußstütze der Stützhebel mitgeschleppt wird, bis er nach Erreichen einer Endstellung beim folgenden manuellen Verschwenken der Fußstütze aus der Gabelöffnung gleitet.In addition, the fork opening is designed so that it tapers towards the opening side with the formation of a flat undercut. This ensures that when the footrest is raised, the support lever is dragged along until it slides out of the fork opening after reaching an end position when the footrest is subsequently pivoted manually.
Bevorzugt besteht die Aufnahmegabel aus einem Kunststoff und ist mit dem Seitenholm der Fußstütze verschraubt. Der Stützhebel kann als Blechformteil ausgebildet und mit dem Rahmen, gleichfalls durch Verschrauben, verbunden sein. In jedem Fall ist die fertigungstechnische Realisierung sowohl des Stützhebels wie auch der Aufnahmegabel mit äußerst geringem Aufwand und damit kostenoptimiert möglich.The receiving fork is preferably made of a plastic and is screwed to the side rail of the footrest. The support lever can be designed as a shaped sheet metal part and connected to the frame, likewise by screwing. In any case, the production-related realization of both the support lever and the receiving fork is possible with extremely little effort and thus cost-effectively.
Die Drehhemmung des Stützhebels erfolgt bspw. über eine Reibbremse, die unterschiedlich gestaltet sein kann. Denkbar ist eine Konstruktion, bei der beidseitig des Stützhebels Reibscheiben angeordnet sind, die, insbesondere durch mindestens eine Druckfeder, bevorzugt eine Tellerfeder gegen den Stützhebel pressbar sind, wobei zur Verspannung eine Schraube sowohl durch die Druckfeder wie auch durch die Reibscheiben und den Stützhebel geführt ist. Eine solche Reibbremse ist in der
In an sich bekannter Weise erfolgt die Verschwenkung der Schenkelstütze und davon abhängig der Fußstütze mittels eines motorischen Antriebs, üblicherweise ein Elektroantrieb, der einerseits an der Schenkelstütze und andererseits am Rahmen gehalten ist, wobei hierzu jeweils ein die entsprechenden Holme miteinander verbindendes stangenförmiges Bauteil vorgesehen ist.In a manner known per se, the thigh support and, depending on it, the footrest are pivoted by means of a motor drive, usually an electric drive, which is held on the one hand on the thigh support and on the other hand on the frame, a rod-shaped component connecting the corresponding spars being provided for this purpose.
Eine andere Lösung dazu wird durch die Erfindung angeboten. Dabei greift der Antrieb nicht unmittelbar an der Schenkelstütze an, sondern an einem Winkelhebel, der schwenkbar an einem Rahmenholm befestigt ist, wobei an einem Hebelschenkel der Motor angelenkt ist, während das freie Ende des anderen Schenkels sich an der Unterseite der Schenkelstütze gleitend abstützt. Für ein reibungsarmes Gleiten ist der Hebelarm mit einer Gleitkappe versehen, auf der die Schenkelstütze aufliegt.Another solution to this is offered by the invention. The drive does not act directly on the thigh support, but on an angle lever that is pivotably attached to a frame spar, the motor being articulated on one lever arm, while the free end of the other arm is slidably supported on the underside of the thigh support. For low-friction sliding, the lever arm is provided with a sliding cap on which the thigh support rests.
Die Anbindung des Motors im vorgenannten Sinn ist auch bei einer weiteren erfindungsgemäßen Ausbildung gegeben, bei der ebenfalls ein Winkelhebel Verwendung findet. Allerdings ist das freie Ende des der Schenkelstütze zugeordneten Schenkels des Winkelhebels mit einer Lenkerlasche verdrehbar verbunden, die andererseits an der Schenkelstütze befestigt ist.The connection of the motor in the aforementioned sense is also given in a further embodiment according to the invention, in which an angle lever is also used. However, the free end of the leg of the angle lever assigned to the thigh support is rotatably connected to a link bracket which, on the other hand, is attached to the thigh support.
Weitere vorteilhafte Ausbildungen der Erfindung sind in den Unteransprüchen gekennzeichnet.Further advantageous developments of the invention are characterized in the subclaims.
