Abstract
Description
Die Erfindung betrifft eine zusammenklappbare Laufhilfe mit einem in Laufrichtung offenen Fahrgestell, mit einem U-förmigen Rahmen, der im Bereich seiner vorderen freien Enden Vorderräder schwenkbar aufnimmt und in dessen hinterem Bereich Seitenstreben schwenkbar in diesem gelagert sind, wobei die Seitenstreben Hinterräder aufnehmen, sowie mit im Fahrgestell gelagerten Stützrohren, die einen Haltebügel oder Haltegriffe höhenverstellbar aufnehmen und mit Einrichtungen zum Begrenzen der Ausklappbewegung des Fahrgestells.The invention relates to a collapsible walker with an open in the running direction undercarriage, with a U-shaped frame which receives front wheels pivotally in the region of its front free ends and in the rear region side struts are pivotally mounted in this, with the side struts receive rear wheels, and with support tubes mounted in the chassis, record a headband or handles height adjustable and with facilities for limiting the unfolding movement of the chassis.
Laufhilfen mit einem in Laufrichtung offenen Fahrgestell und höhenverstellbarem Haltebügel bzw. Haltegriffen zur Anpassung an die Körpergröße sind bekannt. Im Gegensatz zu den üblichen und allgemein bekannten Rollatoren, die vor dem Benutzer hergeschoben werden und dadurch eine leicht gebückte - aus therapeutischer Sicht unerwünschte - Haltung hervorrufen, veranlassen sie den Benutzer zu einer aufrechten Haltung, indem er zwischen dem Fahrgestell-rahmen - und nicht dahinter - steht und die Beine frei nach vorne bewegen kann. Der Bewegungsablauf ist natürlicher. Rücklaufsperren verhindern ein unbeabsichtigtes Rückwärtsrollen, Kippschutze ein Umkippen nach hinten.Running aids with a chassis open in the direction of travel and height-adjustable headband or handles to adjust to the height are known. In contrast to the usual and well-known rollators, which are pushed in front of the user and thus cause a slightly bent - undesirable from a therapeutic point of view attitude, they cause the user to an upright posture by between the chassis frame - and not behind it - stands and the legs can move freely forward. The movement is more natural. Backstops prevent unintentional backward rolling, Kippschutze a tipping backwards.
Bezeichnet werden solche Laufhilfen auch als "Lauflernhilfe", "Posterior Walker", "Control Walker", "Gait Trainer".Such running aids are also referred to as "baby walker", "Posterior Walker", "Control Walker", "Gait Trainer".
Eine zusammenklappbare Laufhilfe der eingangs genannten Art ist beispielsweise durch die Laufhilfe "Nurmi Neo" der Firma Otto Bock HealthCare GmbH, Max-Naeder-Straße 15, D-37115 Duderstadt, bekannt geworden (siehe www.ottobock.de). Bei dieser Laufhilfe sind die im hinteren Bereich des U-förmigen Rahmens angeordneten Seitenstreben als gerade Stangen in der Flucht der Stützrohre positioniert und mit diesen verbunden. Zwischen der Seitenstrebe der jeweiligen Seite der Laufhilfe und dem dieser Seitenstrebe zugewandten Schenkel des U-förmigen Rahmens ist eine Verbindungsstrebe angeordnet, die mit einem Ende schwenkbar in der Seitenstrebe gelagert ist und dessen dem U-förmigen Rahmen zugewandter Bereich mit einem Langloch versehen ist, den eine mit dem Schenkel des U-förmigen Rahmens verbundene Klemmschraube durchsetzt. Kontaktiert die Klemmschraube das dem Schenkel zugewandte Ende des Langlochs ist die Ausklappbewegung des Fahrgestells begrenzt.A collapsible walker of the type mentioned is, for example, by the walker "Nurmi Neo" Otto Bock HealthCare GmbH, Max-Naeder-Straße 15, D-37115 Duderstadt, known (see www.ottobock.de ). In this walker arranged in the rear region of the U-shaped frame side struts are positioned as straight rods in the alignment of the support tubes and connected thereto. Between the side strut of the respective side of the walker and the side strut facing legs of the U-shaped frame, a connecting strut is arranged, which is pivotally mounted with one end in the side strut and the U-shaped frame facing region is provided with a slot a locking screw connected to the leg of the U-shaped frame passes through. If the clamping screw makes contact with the end of the slot facing the leg, the folding movement of the chassis is limited.
Ähnliche Laufhilfen sind durch die Firma HOGGI GmbH, Taunusstraße 17, D-56235 Ransbach-Baumbach, unter der Bezeichnung "FLUX" (siehe auch www.hoggi.de) und durch die Firma R82 GmbH, An den Wiesen 10, D-55218 Ingelheim, unter der Bezeichnung "Crocodile" (siehe auch www.r82.de) bekannt geworden.Similar running aids are by the company HOGGI GmbH, Taunusstraße 17, D-56235 Ransbach-Baumbach, under the name "FLUX" (see also www.hoggi.de ) and by the company R82 GmbH, An den Wiesen 10, D-55218 Ingelheim , under the name "Crocodile" (see also www.r82.de ) become known.
Allen genannten Laufhilfen ist gemeinsam, dass sie wegen der relativ geringen Belastbarkeit lediglich für Kinder und Jugendliche, oder leichte Erwachsene einsetzbar sind. Begründet liegt dies hauptsächlich in der Rahmenkonstruktion, bei der durch die Aufnahme des Haltebügels im Hinterrahmen auf den Vorderrahmen ein großes Biegemoment wirkt und/oder die Gelenkverbindungen zwischen Vorderrahmen, Hinterrahmen und Verbindungsstreben stark belastet werden.All mentioned running aids have in common that they are used because of the relatively low load capacity only for children and adolescents, or light adults. This is mainly due to the frame construction, in which acts by the inclusion of the retaining bracket in the rear frame on the front frame a large bending moment and / or the joints between front frame, rear frame and connecting struts are heavily loaded.
Es ist Aufgabe der vorliegenden Erfindung, eine Laufhilfe der genannten Art so weiter zu bilden, dass diese eine hohe Belastung, insbesondere eine solche von mindestens 100 kg zulässt, wobei die Rahmenteile und Rahmenverbindungen möglichst gering belastet werden sollen. Gleichzeitig soll eine Platz sparende Faltbarkeit gewährleistet sein.It is an object of the present invention to further develop a walking aid of the type mentioned so that it permits a high load, in particular such of at least 100 kg, whereby the frame parts and frame connections are to be loaded as little as possible. At the same time, a space-saving foldability should be ensured.
Gelöst wird die Aufgabe bei einer zusammenklappbaren Laufhilfe der eingangs genannten Art dadurch, dass die Seitenstreben schwenkbar in Schiebern gelagert sind, die in Längsrichtung der Stützrohre verschieblich sind, die Stützrohre schwenkbar in dem U-förmigen Rahmen zwischen den Vorderrädern und den Schwenklagern für die hinteren Seitenstreben gelagert sind, sowie die Einrichtungen zum Begrenzen der Ausklappbewegung des Fahrgestells fest mit den Stützrohren verbunden sind und den Stellweg der Schieber begrenzen.The problem is solved in a collapsible walking aid of the type mentioned in that the side struts are pivotally mounted in slides which are displaceable in the longitudinal direction of the support tubes, the support tubes pivotally in the U-shaped frame between the front wheels and the pivot bearings for the rear side struts are stored, and the means for limiting the Ausklappbewegung the chassis are firmly connected to the support tubes and limit the travel of the slide.
Bei der erfindungsgemäßen zusammenklappbaren Laufhilfe werden somit über den Haltebügel oder die Haltegriffe in die Stützrohre eingeleitete Gewichtskräfte der die Laufhilfe benutzenden Person sowohl unmittelbar in die Schenkel des U-förmigen Rahmens relativ weit vorne als auch in die Seitenstreben eingeleitet, wobei die in die Seitenstreben eingeleiteten Kräfte sowohl unmittelbar zu den Hinterrädern geleitet werden als auch über die weiteren, den Seitenstreben zugeordneten Gelenke in die Schenkel des U-förmigen Rahmens, relativ weit hinten eingeleitet werden. Die Stützrohre sind somit möglichst nahe der Vorderräder am U-förmigen Rahmen angelenkt und es sind die Seitenstreben möglichst nahe der Hinterräder am U-förmigen Rahmen angelenkt.In the collapsible walking aid according to the invention thus introduced via the headband or handles in the support tubes weight forces of the person using the walker are introduced both directly into the legs of the U-shaped frame relatively far forward and in the side struts, wherein the forces introduced into the side struts are guided both directly to the rear wheels as well as via the other, the side struts associated joints in the legs of the U-shaped frame, are introduced relatively far back. The support tubes are thus articulated as close as possible to the front wheels on the U-shaped frame and the side struts are articulated as close as possible to the rear wheels on the U-shaped frame.
Bei der erfindungsgemäßen zusammenklappbaren Laufhilfe ermöglicht die schwenkbare Lagerung der Seitenstreben in den Schiebern und die verschiebliche Anordnung der Schieber in Längsrichtung der Stützrohre ein platzsparendes Zusammenklappen der Laufhilfe. Hierbei bewegen sich die Schieber in Richtung des Haltebügels bzw. der Haltegriffe. Die fest mit den Stützrohren verbundenen Einrichtungen zum Begrenzen der Ausklappbewegung des Fahrgestells begrenzen den Stellweg der Schieber, womit über die Schieber und die Einrichtung zum Begrenzen der Ausklappbewegung des Fahrgestells bei Kontaktierung dieser Teile Kräfte von den Seitenstreben in die Stützrohre eingeleitet werden.In the collapsible walking aid according to the invention, the pivotable mounting of the side struts in the slides and the displaceable arrangement of the slide in the longitudinal direction of the support tubes allows space-saving folding of the walker. Here, the slides move in the direction of the holding bracket or the handles. The fixedly connected to the support tubes means for limiting the Ausklappbewegung the chassis limit the travel of the slide, which are introduced via the slide and the means for limiting the Ausklappbewegung of the chassis upon contacting these parts forces from the side struts in the support tubes.
Die beschriebene Gestaltung der Laufhilfe ermöglicht es, die über den Haltebügel bzw. die Haltegriffe aufgebrachte Belastung in die Rahmenteile möglichst nahe der Räder, insbesondere der Vorderräder einzuleiten.The described design of the walker makes it possible to initiate the load applied via the headband or the handles in the frame parts as close as possible to the wheels, especially the front wheels.
Zur Versteifung der Konstruktion sind vorzugsweise die Seitenstreben mittels einer Querstrebe, insbesondere einer U-förmig angeordneten Querstrebe verbunden. Diese U-förmige Querstrebe ist insbesondere vorne offen. Unter dem Aspekt eines platzsparenden Zusammenklappens der Laufhilfe ist vorgesehen, dass die beiden Seitenstreben die Querstreben, zwischen den Lagern für die Hinterräder und den Schwenkachsen der Seitenstreben im U-förmigen Rahmen, aufnehmen.To stiffen the construction, the side struts are preferably connected by means of a transverse strut, in particular a U-shaped cross strut. This U-shaped cross strut is especially open at the front. Under the aspect of a space-saving folding of the walker is provided that the two side struts, the cross braces, between the bearings for the rear wheels and the pivot axes of the side struts in the U-shaped frame record.
Unter dem Aspekt der möglichst geringen Belastung der Rahmenteile und Rahmenverbindungen sowie der Kippstabilität der Laufhilfe wird es als besonders vorteilhaft angesehen, wenn, bezogen auf die auseinandergefaltete Stellung der Laufhilfe, von oben gesehen, die Stützrohre schräg nach unten und vorne und die Seitenstreben schräg nach unten und hinten gerichtet angeordnet sind.Under the aspect of the lowest possible load on the frame parts and frame connections and the tipping stability of the walker, it is considered to be special considered advantageous when, based on the unfolded position of the walking aid, seen from above, the support tubes are arranged obliquely downwards and forwards and the side struts obliquely downwards and backwards.
Eine besondere Ausführungsform der Erfindung sieht vor, dass Mittel zum lösbaren Festlegen der Schieber in der ausgeklappten Stellung des Fahrgestells vorgesehen sind. Vorzugsweise dienen die Mittel dem Festlegen mindestens eines der Schieber und der dem Schieber zugeordneten Einrichtung zum Begrenzen der Ausklappbewegung des Fahrgestells.A particular embodiment of the invention provides that means are provided for releasably securing the slide in the unfolded position of the chassis. Preferably, the means serve to define at least one of the slides and the slider associated with the means for limiting the Ausklappbewegung the chassis.
Die Mittel, die in dem Festlegen dienen, weisen beispielsweise einen Fanghaken, insbesondere einen mit dem Schieber verbundenen Fanghaken auf, der in eine Hintergriffsstellung mit einer Aufnahme, insbesondere einer stiftförmigen Aufnahme der Einrichtung zum Begrenzen der Ausklappbewegung des Fahrgestells bringbar ist. Der Fanghaken ist beispielsweise mittels einer Feder in Richtung der stiftförmigen Aufnahme vorgespannt, so dass die lösbare Verbindung nur durch aktives Bewegen des Fanghakens entgegen der Federkraft gelöst werden kann.The means used in setting have, for example, a catch hook, in particular a catch hook connected to the slider, which can be brought into a rear grip position with a receptacle, in particular a pin-shaped receptacle of the device for limiting the unfolding movement of the chassis. The catch hook is biased for example by means of a spring in the direction of the pin-shaped receptacle, so that the releasable connection can be achieved only by actively moving the catch against the spring force.
In einer baulich besonders einfachen Gestaltung sind die Einrichtung zum Begrenzen der Ausklappbewegung des Fahrgestells als mit den Stützrohren verbundene Anschläge ausgebildet.In a structurally particularly simple design, the device for limiting the unfolding movement of the chassis are formed as connected to the support tubes stops.
Weitere Merkmale der Erfindung sind in den Unteransprüchen, der Beschreibung der Figuren und den Figuren selbst dargestellt, wobei bemerkt wird, dass alle Einzelmerkmale und alle Kombinationen von Einzelmerkmalen weitere erfinderische Ausgestaltungen darstellen.Further features of the invention are set forth in the subclaims, the description of the figures and the figures themselves, wherein it is noted that all individual features and all combinations of individual features represent further inventive embodiments.

Die zusammenklappbare Laufhilfe 1 weist ein in Laufrichtung A offenes Fahrgestell auf. Ein U-förmiger Rahmen 2 nimmt im Bereich seiner vorderen freien Enden Vorderräder 3 schwenkbar auf. Im hinteren Bereich des U-förmigen Rahmens 2 sind in diesem Seitenstreben 5 um Achsen 8 schwenkbar gelagert. Die Seitenstreben 5 nehmen im Bereich ihrer unteren Enden Hinterräder 7 auf, deren Durchmesser größer ist als der Durchmesser der Vorderräder 3. Die beiden Seitenstreben 5 sind mittels einer U-förmigen Querstrebe 6, die nach vorne offen ist, verbunden. Die Querstrebe 6 greift an den beiden Seitenstreben 5 zwischen den Achsen 8 und den Drehachsen der Hinterräder 7 an. Etwa auf halber Länge zwischen der jeweiligen Achse 8 und dem zugeordneten Vorderrad 3 nimmt der U-förmige Rahmen 2, um eine Achse 9 schwenkbar, ein Stützrohr 10 im Bereich dessen unteren Endes auf. Die beiden Stützrohre 10 sind teleskopierbar und nehmen im Bereich ihres oberen Endes einen U-förmigen Haltebügel 11 auf, der horizontal angeordnet ist und nach vorne offen ist, auf. Die die Schenkel von U-förmigen Rahmen 2, Haltebügel 11 und Querstrebe 6 verbindenden Stege sind, wie der Darstellung der
Bei der Laufhilfe 1 sind somit an dem U-förmigen Rahmen 2 zur Aufnahme der schwenkbaren Vorderräder 3 in dessen hinterem Bereich ein Hinterrahmen 4 zur Aufnahme der Hinterräder 7 mit seinen Seitenstreben 5 in der Achse 8 schwenkbar angelenkt und es sind in dessen vorderem Bereich jeweils links und rechts (im Sinne der Laufrichtung) in der Achse 9 möglichst nahe der Vorderräder 3 die Stützrohre 10 zur höhenverstellbaren Aufnahme des Haltebügels 11 ebenfalls schwenkbar angelenkt. Die Seitenstreben 5 des Hinterrahmens 4 sind zur besseren Stabilität mit der Querstrebe 6 verbunden. Je ein auf den Stützrohren 10 in deren Längsrichtung beweglich geführter Schieber 12 ist mit je einer Seitenstrebe 5 des Hinterrahmens 4 mittels eines Gelenks 18 schwenkbar verbunden. Jeweils ein auf den Stützrohren 10 fest positionierter Schieberanschlag 13 begrenzt die Bewegung der Schieber 12 nach unten, legt die Endposition des Aufklappvorgangs fest und sichert diese mittels in je einem Schieber 12 gelagerten Fanghaken 14 einerseits und je einem im Schieberanschlag integrierten Hakenfang 15 andererseits. Die Sicherung der Klappbewegung und der Endanschlag kann aber auch auf andere Weise bewerkstelligt werden.In the walker 1 are thus on the
Der Vorgang des Zusammenklappens wird durch das Lösen der Fanghaken 14 eingeleitet. Durch Ziehen der nun frei gegebenen Schieber 12 nach oben in Richtung Haltebügel 11 werden sowohl die Stützrohre 10 mit dem Haltebügel 11 als auch der Hinterrahmen 4 kompakt gegen den U-förmigen Rahmen 2 geschwenkt.The process of folding is initiated by the release of the fishing hooks 14.
