Abstract
Description
Die Erfindung bezieht sich auf ein faltbares Gestell mit zwei Seitenrahmen, welche mittels eines Sitzes miteinander verbunden sind, insbesondere für rollende Mobilitätshilfsmittel, Rollstühle, Rollatoren oder ähnliches.The invention relates to a foldable frame with two side frames, which are interconnected by means of a seat, in particular for rolling mobility aids, wheelchairs, walkers or the like.
Im Einzelnen bezieht sich die Erfindung auf einen Faltmechanismus, bei dem ein geteilter, fester Sitz, durch geeignete Ausgestaltung faltbar ausgeführt ist.In detail, the invention relates to a folding mechanism in which a split, fixed seat, designed by suitable design foldable.
Das erfindungsgemäße faltbare Gestell kann beispielsweise in Form eines Faltrollstuhls oder einer Gehhilfe ausgebildet sein, es kann auch als Toilettenrollstuhl oder in anderer Weise Verwendung finden.The foldable frame according to the invention can be designed for example in the form of a folding wheelchair or walker, it can also be used as a toilet wheelchair or in other ways.
Die aus dem Stand der Technik bekannten Konstruktionen weisen entweder Scherenverbindungen auf, mittels der die beiden Seitenrahmen so verbunden sind, dass sie aneinander angenähert oder voneinander beabstandet werden können. Dabei sind diese Scherenmechanismen jeweils in der Sitzposition und/oder der zusammengelegten Position sperrbar. Die bekannten Konstruktionen weisen jeweils flexible Sitztücher auf, die beim Zusammenlegen des faltbaren Gestells gefaltet werden. In der Gebrauchsstellung sind diese Konstruktionen aus ästhetischen Gründen nicht zu bevorzugen, da sich keine ebene Sitzfläche ergibt. Bei längerem Gebrauch dehnen sich die Sitztücher, so dass die Sitzfläche weiter durchhängt. Insgesamt ergibt sich eine Konstruktion, welche vielfach einen nicht sehr stabilen Eindruck macht und insbesondere optischen Anforderungen meist nicht genügt.The constructions known from the prior art have either scissor connections, by means of which the two side frames are connected so that they can be approximated or spaced from one another. These scissor mechanisms can be locked in the sitting position and / or the folded position. The known constructions each have flexible seats, which are folded when folding the foldable frame. In the position of use, these constructions are not preferable for aesthetic reasons, since there is no flat seat. With prolonged use, the towels stretch so that the seat sags on. Overall, a construction results, which often makes a not very stable impression and in particular optical requirements usually not enough.
Der Erfindung liegt die Aufgabe zugrunde, ein faltbares Gestell der eingangs genannten Art zu schaffen, welches bei einfachem Aufbau und einfacher, kostengünstiger Herstellbarkeit eine feste Sitzfläche bietet und hohen optischen Anforderungen genügt.The invention has for its object to provide a foldable frame of the type mentioned, which offers a solid seat with a simple design and simple, cost manufacturability and high optical requirements.
Erfindungsgemäß wird die Aufgabe durch die Merkmalskombination des Anspruchs 1 gelöst, die Unteransprüche zeigen weitere vorteilhafte Ausgestaltungen der Erfindung.According to the invention the object is achieved by the combination of features of claim 1, the dependent claims show further advantageous embodiments of the invention.
Erfindungsgemäß ist somit ein faltbares Gestell mit zwei Seitenrahmen vorgesehen, welche mittels eines Sitzes miteinander verbunden sind. Dabei ist der Sitz als starrer Sitz ausgebildet, welcher durch zwei starre, plattenartige Sitzelemente gebildet wird, welche gelenkig miteinander verbunden sind. Somit liegt ein, bezogen auf das faltbare Gestell, mittiges Gelenk vor, so dass die beiden plattenartigen Sitzelemente jeweils zu der Gelenkachse symmetrisch aufgebaut sind.According to the invention thus a foldable frame is provided with two side frames, which are interconnected by means of a seat. In this case, the seat is designed as a rigid seat, which is formed by two rigid, plate-like seat elements, which are hinged together. Thus, based on the foldable frame, there is a central joint, so that the two plate-like seating elements are symmetrical in each case to the hinge axis.
Die jeweils anderen Enden der Sitzelemente sind gelenkig mit dem jeweiligen Seitenrahmen verbunden. Bei einem Zusammenlegen des faltbaren Gestells durch Annäherung der beiden Seitenrahmen werden somit die beiden Sitzelemente zueinander und zu dem jeweiligen Seitenrahmen verschwenkt.The respective other ends of the seat elements are hingedly connected to the respective side frame. In a collapsing of the foldable frame by approaching the two side frames thus the two seat elements are pivoted to each other and to the respective side frame.
Um eine ausreichende Stabilität zu gewährleisten und um den Bewegungsablauf beim Zusammenlegen bzw. Aufstellen des faltbaren Gestells zu sichern, ist erfindungsgemäß weiterhin ein Koppelgetriebe vorgesehen, welches die Seitenrahmen und die Sitzelemente miteinander verbindet.In order to ensure sufficient stability and to ensure the sequence of movement when folding or setting up the foldable frame, according to the invention a coupling mechanism is further provided, which connects the side frame and the seat elements together.
Ein wesentlicher Aspekt der erfindungsgemäßen Ausgestaltung liegt auch darin, dass in der aufgeklappten Sitzstellung zumindest ein Teil des Koppelgetriebes in Ausnehmungen an der Unterseite der Sitzelemente aufgenommen ist. Das Koppelgetriebe ist somit im betriebsbereiten, aufgeklappten Zustand für den Benutzer nicht sichtbar, so dass sich eine stabile und auch optisch den höchsten Anforderungen genügende Gesamtkonstruktion ergibt.An essential aspect of the embodiment according to the invention is also that, in the unfolded sitting position, at least part of the linkage is received in recesses on the underside of the seat elements. The coupling gear is thus not visible in the operational, unfolded state for the user, so that there is a stable and visually the highest requirements sufficient overall construction.
Erfindungsgemäß ist bevorzugter Weise das Koppelgetriebe nur an einem Seitenbereich der Sitzelemente und der Sitzrahmen angeordnet. Dies bedeutet beispielsweise, dass, wenn ein Benutzer auf dem faltbaren Gestell sitzt, sich das Koppelgetriebe entweder an der vorderen oder an der hinteren Seite der Sitzelemente befindet. Somit wird ein Freiraum geschaffen, der es beispielsweise gestattet, das erfindungsgemäße faltbare Gestell als Toilettenstuhl oder in ähnlicher Weise auszugestalten. Das Koppelgetriebe gestattet es somit, beispielsweise im mittigen Bereich des Sitzes einen Hygieneausschnitt vorzusehen. Somit kann das faltbare Gestell beispielsweise auch als Duschsitz verwendet werden.According to the invention, the coupling mechanism is preferably arranged only on a side region of the seat elements and the seat frame. This means, for example, that when a user sits on the foldable frame, the linkage is located either on the front or on the rear side of the seat elements. Thus, a free space is created, which allows, for example, to design the foldable frame according to the invention as a toilet chair or in a similar manner. The coupling gear thus allows, for example, in the center The area of the seat to provide a hygiene cutout. Thus, the foldable frame can be used for example as a shower seat.
In besonders günstiger Weiterbildung der Erfindung ist vorgesehen, dass das Koppelgetriebe jeweils ein Viergelenkgetriebe umfasst, welches die Sitzelemente miteinander koppelt. Weiterhin ist jeweils eine Koppelstange vorgesehen, die das Viergelenkgetriebe gelenkig mit einem unteren Bereich des jeweiligen Seitenrahmens verbindet. Hierdurch wird sichergestellt, dass sich eine parallelogrammartige Konstruktion ergibt, welche insbesondere für einen synchronen Faltablauf beider Seitenrahmen sorgt.In a particularly favorable development of the invention, it is provided that the coupling mechanism each comprise a four-bar linkage which couples the seat elements together. Furthermore, in each case a coupling rod is provided, which connects the four-bar linkage articulated to a lower portion of the respective side frame. This ensures that results in a parallelogram-like construction, which provides in particular for a synchronous Faltablauf both side frames.
Das Viergelenkgetriebe umfasst bevorzugter Weise zwei Streben, welche an jeweils einem Ende gelenkig miteinander verbunden sind und deren andere Enden jeweils gelenkig mit dem jeweils einen der Sitzelemente verbunden sind. Eine derartige Konstruktion ist einfach und kostengünstig herstellbar und gestattet es, das Koppelgetriebe, wie erwähnt, in der bevorzugter Weise schlitzartig ausgebildeten Ausnehmung an der Unterseite der Sitzelemente in der Sitzstellung aufzunehmen.The four-bar linkage preferably comprises two struts which are hingedly connected to one another at each end and whose other ends are each pivotally connected to the respective one of the seat elements. Such a construction is simple and inexpensive to produce and allows the coupling gear, as mentioned, to receive in the preferred manner slot-like recess on the underside of the seat elements in the sitting position.
Die Koppelstange ist bei der oben beschriebenen Ausgestaltung bevorzugter Weise mit einem ihrer Enden mit der Gelenkverbindung der Streben verbunden, während das andere Ende der Koppelstange an einem unten liegenden Bereich des jeweiligen Seitenrahmens gelenkig angeordnet ist.The coupling rod is preferably connected in the embodiment described above with one of its ends to the articulated connection of the struts, while the other end of the coupling rod is articulated to a lower region of the respective side frame.
Die gelenkige Verbindung der beiden Sitzelemente ist bevorzugter Weise so ausgebildet, dass sich ein Totpunkt bildet. Hierzu ist die gelenkige Verbindung bevorzugt an der Unterseite der beiden Sitzelemente angeordnet (bezogen auf den aufgeklappten Sitz-Zustand. Somit stützen sich die beiden Sitzelemente oberhalb der scharnierartigen Verbindung gegeneinander ab, so dass sich das System im auseinandergefalteten sitzbereiten Zustand selbst stabilisiert.The articulated connection of the two seat elements is preferably designed so that a dead center is formed. For this purpose, the articulated connection is preferably arranged on the underside of the two seat elements (based on the unfolded seat state.) Thus, the two seat elements are supported above one another above the hinge-like connection, so that the system stabilizes itself in the unfolded state ready for sitting.
Besonders günstig ist, wenn die beiden Sitzelemente an ihrem Verbindungsbereich mittels eines zusätzlichen Sperrmechanismus gegeneinander verriegelbar sind. Auf diese Weise wird verhindert, dass sich das erfindungsgemäße faltbare Gestell unbeabsichtigter Weise beim Anheben selbst zusammenfaltet. Bei einer derartigen Verriegelung könnte auch vorgesehen sein, auf die oben beschriebene Totpunktregelung zu verzichten.It is particularly advantageous if the two seat elements can be locked against each other at their connection area by means of an additional locking mechanism. On This way it is prevented that foldable frame according to the invention unintentionally folds when lifting itself. In such a lock could also be provided to dispense with the dead center control described above.
Die gelenkige Verbindung zwischen dem Seitenrahmen und dem Sitzelement erfolgt bevorzugter Weise über ein U-förmiges bzw. gekrängtes Lagerelement. Dieses ermöglicht es, den Gelenkbereich der Verbindung zwischen den Sitzelementen und den Seitenrahmen jeweils insbesondere in der zusammengelegten Stellung platzsparend unterzubringen.The articulated connection between the side frame and the seat element is preferably carried out via a U-shaped or cranked bearing element. This makes it possible to accommodate the joint region of the connection between the seat elements and the side frames, in particular in the folded position to save space.
Durch die extrem flache Bauweise des erfindungsgemäßen Faltsystems in Verbindung mit einem festen Sitz, der beispielsweise, wie erwähnt, auch mit einem Hygieneausschnitt versehen sein kann, ist es möglich, das erfindungsgemäße faltbare Gestell als Faltrollstuhl auszubilden, welches auch als Toilettenrollstuhl verwendet werden kann. Dabei ist, da das Koppelgetriebe mit den Koppelstangen sich an einer Seite des Sitzes befindet, ein Überfahren einer Toilette möglich.Due to the extremely flat design of the folding system according to the invention in conjunction with a fixed seat, which may be provided, for example, as mentioned, with a hygiene cutout, it is possible to form the foldable frame according to the invention as a folding wheelchair, which can also be used as a toilet wheelchair. It is because the coupling mechanism with the coupling rods located on one side of the seat, a running over a toilet possible.
Ein weiterer Vorteil der erfindungsgemäßen Ausgestaltung liegt darin, dass die feste Konstruktion des Sitzes ein hohes Maß an Sitzkomfort gewährleistet und die Dekubitus-Gefahr verringert.Another advantage of the embodiment of the invention is that the solid construction of the seat ensures a high degree of comfort and reduces the pressure ulcer risk.
