Description

Die Erfindung betrifft eine Gehhilfe nach dem Oberbegriff des Hauptanspruchs.The invention relates to a walking aid according to the preamble of Main claim.

Aus den Stand der Technik sind unterschiedlichste Ausgestaltungsformen derartiger Gehhilfen vorbekannt, üblicherweise weisen diese einen Rohr-Rahmen auf, an welchem die Handgriffe und die Bremshebel integriert sind.A wide variety of design forms are from the prior art Such walking aids previously known, usually point this a tubular frame on which the handles and the brake levers are integrated.

Bei Gehhilfen der beschriebenen Art müssen mehrere Funktionen erfüllt sein. Zum einen muß sich die Bedienungsperson sicher auf der Gehhilfe abstützen können. Diese muß kippsicher sein, unabhängig von der jeweiligen Stellung der lenkbaren Räder. Weiterhin muß die Gehhilfe so konzipiert sein, daß die Bedienungsperson auch beim Bremsen und/oder Lenken nicht aus dem Gleichgewicht kommt. Die Gehhilfe muß insbesondere für ungeübte Bedienungspersonen ausreichend sicher betätigbar sein, so daß auch bei plötzlich auftretenden Schwierigkeiten, sei es hinsichtlich der Bodenbeschaffenheit oder bei plötzlichen Schwächezuständen der Bedienungsperson sowohl ein Abstützen als auch ein sicheres Bremsen der Gehhilfe gewährleistet ist.With walking aids of the type described have several functions be fulfilled. First, the operator must be sure can rest on the walking aid. This must be safe from tipping over regardless of the position of the steerable wheels. Furthermore, the walking aid must be designed so that the operator even when braking and / or steering from the Balance comes. The walking aid must be especially for inexperienced Operators must be sufficiently safe to operate so that even in the event of sudden difficulties, be it in terms of the condition of the ground or in the event of sudden weakness the operator both a support as well safe braking of the walking aid is guaranteed.

Die DE U 93 03 081 beschreibt ein von Behinderten geführtes Fahrgerät, welches auch als Gehhilfe bezeichnet wird. Dieses Fahrgerät ist mit Brems-Handhebeln versehen, die im nicht-betätigten Zustand das Fahrgerät bremsen. Es handelt sich somit um eine automatische "Totmann-Bremse". Durch Betätigung der Brems-Handhebel wird der Bremsandruck aufgehoben und das Fahrgerät fahrbereit. Die Brems-Handhebel kennen somit lediglich eine Betätigungsrichtung, die zur Lösung der Bremse dient. Bei einem leichten Bremsen muß die Bedienungsperson die Betätigung der Bremse langsam nachlassen, die Bremse kehrt dann letztlich in die "Totmann-Bremse" zurück.DE U 93 03 081 describes a run by disabled people Driving device, which is also called walking aid. This Driving device is provided with brake hand levers, which in the non-operated Brake the vehicle. So it is an automatic "dead man's brake". By pressing the Brake hand lever releases the brake pressure and the driving device ready for driving. The brake hand levers therefore only know an actuation direction that serves to release the brake. At The operator must actuate the brake lightly the brake slowly releases, the brake finally turns back into the "dead man's brake".

Der Erfindung liegt die Aufgabe zugrunde, eine Gehhilfe der eingangs genannten Art zu schaffen, welche bei einfachem Aufbau und kostengünstiger Herstellbarkeit sicher bedienbar ist und insbesondere sichere Bremsfunktionen gewährleistet.The invention has for its object a walking aid to create the type mentioned above, which with a simple structure and inexpensive to manufacture is safe to use and guaranteed safe braking functions in particular.

Erfindungsgemäß wird die Aufgabe durch die Merkmale des Hauptanspruchs gelöst.According to the invention the object is characterized by the features of the main claim solved.

Die Unteransprüche zeigen weitere vorteilhafte Ausgestaltungen der Erfindung.The subclaims show further advantageous refinements the invention.

Die erfindungsgemäße Gehhilfe zeichnet sich durch eine Reihe erheblicher Vorteile aus. Durch die erfindungsgemäß vorgesehene Ausgestaltung des Griffs und des zugehörigen Bremshebels ist gewährleistet, daß die Bedienungsperson den Griff frei und ungehindert ergreifen kann. Dies war bei den aus dem Stand der Technik bekannten, einen hinten geschlossenen Rohrbogen aufweisenden Griffen nicht immer gewährleistet, bei diesen Ausgestaltungen ergab sich insbesondere das Problem, daß der schnelle Zugriff auf den Bremshebel vielfach blockiert war.The walking aid according to the invention is characterized by a number significant benefits. By the provided according to the invention Design of the handle and the associated brake lever is ensures that the operator has a free and unimpeded grip can take. This was the case with the state of the art Known technology, having a pipe bend closed at the rear Handles are not always guaranteed with these designs in particular the problem arose that the fast Access to the brake lever was blocked many times.

Erfindungsgemäß ist vorgesehen, daß jeweils ein äußerer Seitenrahmen vorgesehen ist, welcher in Form eines in einer Ebene geformten Elements ausgeformt ist, an dessen unterem freiem Ende ein Rad und an dessen oberem, nach hinten weisenden Ende der Handgriff angebracht ist, daß innenliegend zu dem äußeren Seitenrahmen ein die Vorderräder tragender Innenrahmen angeordnet ist und daß die Bremshebel jeweils unter dem Handgriff frei nach hinten vorstehend gelagert und an den Hinterrädern befindlichen Bremsen zugeordnet sind.According to the invention it is provided that an outer side frame is provided, which is shaped in the form of a plane Elements is formed, at its lower free end a wheel and at its upper, rear-facing end the Handle is attached to the inside of the outer side frame an inner frame carrying the front wheels is arranged and that the brake lever is free under the handle stored rearward and located on the rear wheels Brakes are assigned.

Durch die erfindungsgemäß vorgesehene Ausgestaltung des Rahmens weisen die Hinterräder eine größere Spurweite auf, als die Vorderräder. Diese Konstruktion vereinfacht Kurvenfahrten und verbessert die Lenkfähigkeit der gesamten Gehhilfe, weist jedoch, bedingt durch die vier Räder, ein hohes Maß an Standsicherheit auf.Due to the design of the frame provided according to the invention the rear wheels have a larger track width than the front wheels. This construction simplifies cornering and improves the ability to steer the entire walking aid, however, indicates due to the four wheels, a high degree of stability on.

Ein weiterer, wesentlicher Vorteil ergibt sich aus der größeren mechanischen Festigkeit des Gestells, da der äußere, in sich geschlossene Rahmen hohe Kräfte aufnehmen kann, die auch schwereren Personen eine sichere Benutzung der Gehhilfe ermöglichen. Hinzu kommt, daß die äußeren Seitenrahmen jeweils nur in einer Ebene verformt sind. Dies führt zu einer erheblichen Vereinfachung der Herstellung.Another major advantage comes from the larger one mechanical strength of the frame, since the outer, in itself closed frames can absorb high forces, which are also heavier Allow people to use the walking aid safely. In addition, the outer side frames only in one Plane are deformed. This leads to a considerable simplification the production.

In bevorzugter Weiterbildung der Erfindung ist vorgesehen, daß der obere Bereich des äußeren Seitenrahmens höhenverstellbar ist. Die Höhenverstellung ist somit an der Vorderseite der Gehhilfe angeordnet. Hierdurch wird sie gut zugänglich, andererseits ist sichergestellt, daß die Bedienungsperson nicht in ungewollter Weise die Höhenverstellung lockert oder an dieser hängenbleibt. Der äußere Seitenrahmen bildet somit, zusammen mit der bevorzugterweise teleskopartig ausgebildeten Höhenverstell-Einrichtung eine in sich geschlossene Einheit.In a preferred development of the invention it is provided that the upper area of the outer side frame is height adjustable is. The height adjustment is therefore on the front the walking aid arranged. This makes it easily accessible on the other hand, it ensures that the operator not inadvertently the height adjustment loosens or gets stuck. The outer side frame thus forms, together with the preferably telescopic trained height adjustment device one in itself closed unit.

Weiterhin ist es vorteilhaft, wenn der Innenrahmen zwei zueinander parallele, jeweils in einer Ebene angeordnete Innenträger umfaßt, welche miteinander verstrebt sind. Die Innenträger sind bevorzugterweise ebenfalls nur in einer Ebene verformt, ihre Innenlage - bezogen auf die äußeren Seitenrahmen - führt zu der verminderten Spurbreite der lenkbaren Vorderräder. Die Verstrebung kann in geeigneter Weise erfolgen, es ist auch möglich, einen Teil der Verstrebung zur Lagerung einer Sitzfläche zu nutzen.It is also advantageous if the inner frame two parallel to each other, each arranged in one plane Includes inner beams, which are braced together. The Inner beams are also preferably only in one Plane deformed, its inner layer - in relation to the outer Side frame - leads to the reduced track width of the steerable front wheels. The strut can be more appropriate Way, it is also possible to use some of the bracing to use for storing a seat.

Durch die erfindungsgemäß gewählte Ausgestaltung der äußeren Seitenrahmen und der Innenträger ist es möglich, das gesamte Gestell der Gehhilfe auf besonders einfache Weise zusammenzuklappen, um die Transportmaße zu verringern. Ein geeigneter Entriegelungsmechanismus kann im mittleren Bereich der Gehhilfe so angebracht werden, daß er unterhalb einer Sitzfläche liegt und somit vor Fehlbedienungen geschützt ist.Due to the design of the outer selected according to the invention Side frame and the inner support it is possible to cover the whole Folding the frame of the walking aid in a particularly simple manner, to reduce the transport dimensions. A suitable one Unlocking mechanism can be in the middle of the range Walking aid should be attached so that it is below a seat lies and is therefore protected against incorrect operation.

Die Sitzfläche kann aus einem Drahtgeflecht oder einer Kunststoffplatte bestehen, dabei kann es günstig sein, wenn die Sitzfläche fest mit dem inneren Rohrrahmen verbunden ist.The seat can be made of wire mesh or a plastic plate, it can be cheap be when the seat is tight with the inner tubular frame connected is.

Besonders günstig ist es, wenn der Bremshebel schlaufenartig ausgebildet ist und zur besseren Bedienbarkeit mit verbreiterten Griffflächen versehen ist. Die schlaufenartige Ausbildung gestattet es der Bedienungsperson, den Bremshebel in unterschiedlichen Griffpositionen jeweils fest und betriebssicher zu greifen. Hierbei wird verhindert, daß die Bedienungsperson von dem Bremshebel abrutscht. Sie kann diesen vielmehr mit der Hand durchgreifen und sich insbesondere mit dem Handballen abstützen bzw. sämtliche Finger zum Bremsen verwenden.It is particularly favorable if the brake lever is loop-like is trained and for better usability with widened Grip surfaces is provided. The loop-like training allows the operator to put the brake lever in different grip positions each firm and reliable to grab. This prevents the operator slips off the brake lever. You can do this rather reach through with your hand and especially with support the ball of the hand or all fingers to brake use.

Weiterhin ist es besonders vorteilhaft, wenn ein seitlicher Teil des Bremshebels nach außen mit einem verbreiterten Schutzbereich versehen ist. Dieser Schutzbereich erstreckt sich soweit nach außen, daß die Bedienungsperson auch dann, wenn sie versehentlich seitlich an eine Wand oder ein ähnliches Hindernis fährt, hinsichtlich ihrer Hände geschützt ist. Die Hände stehen somit seitlich nicht über, vielmehr bildet der verbreiterte Schutzbereich des Bremshebels einen Anschlag, mit welchem sich die Gehhilfe an einer Wand etc. abstützt.Furthermore, it is particularly advantageous if a side Part of the brake lever to the outside with a widened Protection area is provided. This protection area extends to the extent that the operator can if they accidentally hit the side of a wall or something similar Obstacle drives, protected with regard to their hands is. The hands do not protrude laterally, rather the widened protection area of the brake lever forms one Stop with which the walking aid is attached to a wall etc. supports.

Erfindungsgemäß ist die Bremse als Doppelfunktions-Bremse ausgebildet, sie dient einerseits als Betriebsbremse und andererseits als Feststellbremse. In beiden Fällen wirkt die Bremse reibschlüssig auf die Hinterräder. Diese Ausgestaltung ist technisch besonders einfach zu verwirklichen und zeichnet sich durch ein hohes Maß an Betriebssicherheit aus. Dabei kann es besonders günstig sein, wenn die Bremse durch entgegengesetzte Verschwenkung des Bremshebels bedient werden kann. Ein Niederdrücken des Bremshebels beaufschlagt die Feststellbremse(Parkbremse), während ein Anziehen des Bremshebels die Betriebsbrems-Funktion betätigt. Sollte die Bedienungsperson, beispielsweise in einem Notfall, mit ihrer vollen Abstütz-Kraft den Bremshebel nach unten verschwenken, so wird hierdurch ein wirkungsvolles Betätigen der Feststellbremse hervorgerufen, die Gehhilfe kann nicht weiter bewegt werden und kommt zum völligen Stillstand.According to the invention, the brake is a double-function brake trained, it serves as a service brake and on the other hand as a parking brake. It works in both cases Brake on the rear wheels. This configuration is technically particularly easy to implement and is characterized by a high degree of operational safety. It can be particularly advantageous if the brake is applied opposite pivoting of the brake lever are operated can. Depressing the brake lever acts on the Parking brake (parking brake) while pulling the brake lever Service brake function activated. If the operator for example, in an emergency, with their full Support force swivel the brake lever down, see above is an effective application of the parking brake caused, the walking aid can not be moved and comes to a complete standstill.

Zur Begrenzung der Sitzfläche ist erfindungsgemäß ein Sicherungsbügel vorgesehen, welcher den vorderseitigen Bereich der Sitzfläche - bezogen auf die Fahrtrichtung - begrenzt, Um den Aufbau der Gehhilfe besonders einfach zu gestalten, ist es günstig, wenn der Sicherungsbügel an seinem freien Ende jeweils an einem Trägerelement des Bremshebels gelagert ist. Das Trägerelement kann über das freie Ende des Griffrohres des äußeren Seitenrahmens geschoben werden und bildet mit dem Bremsgriff eine in sich geschlossene Einheit.According to the invention, a securing bracket is used to limit the seating surface provided which is the front area the seat - limited in relation to the direction of travel - To make the construction of the walking aid particularly easy, it is convenient if the safety bracket on its free End each mounted on a support member of the brake lever is. The carrier element can over the free end of the handle tube of the outer side frame are pushed and forms with the brake handle a self-contained unit.

Die Räder sind vorzugsweise mit einer Vollgummi-Bereifung versehen, welche sich durch eine besondere Leichtläufigkeit auszeichnen.The wheels are preferably with solid rubber tires provided, which is characterized by a special smoothness award.

Wie aus den Fig. 1 und 2 ersichtlich ist, weist die erfindungsgemäße Gehhilfe zwei Vorderräder 1, 2 sowie zwei Hinterräder 7, 8 auf. Die Vorderräder 1, 2 sind jeweils um eine vertikale Achse lenkbar, während die Drehachsen der Hinterräder 7, 8 nicht-lenkbar gelagert sind. Auf die Detail-Konstruktion der Radaufhängung kann verzichtet werden, da diese aus dem Stand der Technik bekannt ist.As can be seen from FIGS. 1 and 2, the invention has Walking aid two front wheels 1, 2 and two rear wheels 7, 8 on. The front wheels 1, 2 are each one vertical axis steerable, while the axes of rotation of the rear wheels 7, 8 are non-steerable. On the detail construction the wheel suspension can be dispensed with as this is known from the prior art.

Die Fig. 2 zeigt im Detail den Aufbau der erfindungsgemäß vorgesehenen Bremse 9, diese umfaßt ein hebelartiges, um eine Achse 19 schwenkbares Bremselement 18, dessen freie Enden jeweils als Betriebsbremse bzw. Feststellbremse wirksam sind. Die Betätigung des Bremselements 18 erfolgt über einen im einzelnen nicht dargestellten Seilzug 20 (siehe Fig. 1), über Bremshebel 5, 6, welche jeweils schwenkbar am Trägerelement 17 gelagert sind. Die Form der Bremshebel 5, 6 wird nachfolgend im Zusammenhang mit den Figuren 3 bis 7 erläutert.2 shows in detail the structure of the invention provided brake 9, this includes a lever-like to an axis 19 pivotable brake element 18, the free Each ends as a service brake or parking brake are. The brake element 18 is actuated via a cable 20, not shown in detail (see Fig. 1), via brake levers 5, 6, which are each pivotable on Carrier element 17 are mounted. The shape of the brake levers 5, 6 is subsequently used in connection with FIGS. 3 to 7 explained.

Aus den Fig. 1 und 2 ist weiterhin ersichtlich, daß die beiden äußeren Seitenrahmen, welche parallel zueinander angeordnet sind, jeweils in einer Ebene verformt sind und einen oberen, fast U-förmigen Bereich aufweisen. Dieser dient mit seinem freien, vorstehenden Ende zur Anbringung von Handgriffen 3, 4 sowie zur Lagerung der Trägerelemente 17 der Bremshebel 5, 6. Weiterhin ist der Basisbereich, d.h. der obere Bereich des äußeren Seitenrahmens 10 höhenverstellbar, dieser obere Bereich ist in den Fig. 1 und 2 mit dem Bezugszeichen 13 gekennzeichnet. Die Höhenverstellung kann durch eine teleskopartige Ausbildung erreicht werden, welche mittels einer Klemmschraube 22 betätigbar ist.1 and 2 that the two outer side frame, which are arranged parallel to each other are deformed in one plane and one have upper, almost U-shaped area. This serves with its free, protruding end for attaching handles 3, 4 and for mounting the support elements 17 of the Brake levers 5, 6. Furthermore, the base area, i.e. the upper area of the outer side frame 10 adjustable in height, this upper area is in FIGS. 1 and 2 with the reference symbol 13 marked. The height adjustment can be done by a telescopic training can be achieved, which means a clamping screw 22 can be actuated.

Die Fig. 1 und 2 zeigen weiterhin, daß das untere, freie Ende 11 des Seitenrahmens 10 das Hinterrad 7, 8 trägt.1 and 2 further show that the lower, free End 11 of the side frame 10 carries the rear wheel 7, 8.

Parallel zu dem äußeren Seitenrahmen 10 ist ein Innenrahmen 12 angeordnet, welcher über eine Schwenkachse 21 relativ zu dem äußeren Seitenrahmen 10 verschwenkbar ist. An inner frame is parallel to the outer side frame 10 12 arranged, which relative to a pivot axis 21 the outer side frame 10 is pivotable.

Diese Streben dienen zum einen zur Stabilisierung des Gestells, zum anderen ist die obere Strebe 23 als Auflage für eine Sitzfläche 14 nutzbar.The two inner frames 12 are by horizontal struts 23 connected with each other. On the one hand, these struts serve Stabilization of the frame, on the other hand, the upper strut 23 usable as a support for a seat 14.

Aus den Figuren ist weiterhin ersichtlich, daß parallel zu jedem äußeren Seitenrahmen 10 der Seilzug 20 der zugeordneten Bremse verläuft.From the figures it can also be seen that parallel to each outer side frame 10 of the cable 20 of the associated Brake runs.

Weiterhin ist ein Sicherungsbügel 15 vorgesehen, welcher mit seinen beiden freien Enden an den Trägerelementen 17 verankert ist und die Sitzfläche 14 nach vorne begrenzt und somit als Rückenlehne dient.Furthermore, a safety bracket 15 is provided, which with its two free ends anchored to the carrier elements 17 is and the seat 14 limited to the front and thus serves as a backrest.

Die Fig. 3 bis 7 zeigen in unterschiedlichen Ansichten jeweils die Ausgestaltung des erfindungsgemäßen Bremshebels 5 (bzw. 6) sowie des zugeordneten Trägerelements 17. Das Trägerelement 17 weist einen rohrförmigen Bereich 24 auf, in welchem das freie Ende des Seitenrahmens 10 einsteckbar und mittels Befestigungen 25 (Schrauben) fixierbar ist. Eine Anlage 27 dient zur seitlichen Abstützung.3 to 7 show in different views each the design of the brake lever according to the invention 5 (or 6) and the associated carrier element 17. Das Carrier element 17 has a tubular region 24, in which the free end of the side frame 10 insertable and can be fixed by means of fastenings 25 (screws). A Appendix 27 is used for lateral support.

An dem Trägerelement 17 ist weiterhin ein Nippel 26 befestigt, in welchen der Seilzug 20 eingehängt wird.A nipple 26 is also attached to the carrier element 17, in which the cable 20 is hooked.

An dem Trägerelement ist schwenkbar der Bremshebel 5, 6 gelagert, dieser ist, wie aus den Figuren ersichtlich in Form einer geschlossenen Schlaufe ausgebildet, welche verbreitert ausgestaltet ist. Die untere Fläche des Bremshebels 5, 6 ist mit einem verbreiterten Schutzbereich 16 versehen, welcher, wie insbesondere aus Fig. 6 ersichtlich ist, über den Bremshebel 5, 6 übersteht und auf diese Weise die Hand einer Bedienungsperson schützt, falls die Gehhilfe gegen eine Wand gefahren wird.The brake lever 5, 6 can be pivoted on the carrier element stored, this is, as can be seen from the figures in Formed a closed loop, which widens is designed. The lower surface of the brake lever 5, 6 is provided with an enlarged protective area 16, which, as can be seen in particular from FIG. 6, via the brake lever 5, 6 protrudes and in this way the hand protects an operator if the walking aid against a wall is driven.

Der Bremshebel 5, 6 ist in den Fig. 3 bis 7 jeweils in der neutralen Position gezeigt, er kann sowohl nach oben als auch nach unten verschwenkt werden.The brake lever 5, 6 is in Figs. 3 to 7 each in the shown neutral position, it can be both up and down can also be pivoted downwards.

Durch die oben beschriebene Ausgestaltung des Bremshebels mit den verbreiterten Auflageflächen ergibt sich somit der Vorteil, daß bei der Betätigung der Bremse an der Hand der Bedienungsperson eine geringere Flächenpressung auftritt, da die Auflagekraft, welche mit der Hand aufgebracht wird, auf einen größeren Bereich verteilt wird. Verletzungen der Haut, Rötungen, Druckstellen etc. können somit vermieden werden. Hierzu kann es zusätzlich günstig sein, eine entsprechende Oberflächenbeschichtung auf den Bremshebel aufzubringen, beispielsweise in Form einer gummierten Schicht, einer Moosgummischicht etc. Die beschriebene Form des Bremshebels erhöht weiterhin die Treffsicherheit, so daß auch in hektischen Situationen eine sichere Betätigung der Bremse erfolgen kann.Due to the design of the brake lever described above with the widened contact surfaces, the result is Advantage that when operating the brake on the hand Operator a lower surface pressure occurs because the contact force, which is applied by hand a larger area is distributed. Skin injuries, Redness, pressure marks etc. can thus be avoided. For this purpose, it may also be advantageous to have a corresponding one Apply surface coating to the brake lever, for example in the form of a rubberized layer, a foam rubber layer etc. The shape of the brake lever described increases continue the marksmanship, so that even in hectic Safe brake application can.
