Definitions

  • the present invention relates to a Wheelchair.
  • EP-0 887 064-A2 which forms part of the state of the art under Article 54 (3) EPC, describes, for example, a wheelchair of the type mentioned at the beginning; whose frame is closed and therefore relatively rigid.
  • This frame consists of a front horizontal cross member at user height, a rear horizontal cross member which is formed by an axle tube of the rear wheel pair, and two L-shaped side members, each of which connects one end of the front cross member to one end of the rear cross member, each side carrier has an upright leg and a longitudinal leg.
  • a front wheel device with a single central front wheel or with two spaced front wheels is attached to the front cross member.
  • This wheelchair has a high degree of rigidity and, thanks to the front wheel device which is generally arranged in the central region of the front crossmember, is easy to turn and easy to maneuver. It is mainly used as a sports wheelchair.
  • the main disadvantage of this wheelchair is its low stability against tipping; it is therefore less suitable for everyday use and is considered unsuitable for severely disabled and older users.
  • Elements of the wheelchair described in EP-0 887 046 A2 have become known through an obvious prior use. This apparent prior use is regarded as the closest prior art and forms the preamble of claim 1.
  • a wheelchair is known from EP-0 255 804-A2 , which has a front cross member at foot height, two side members and a rear cross member in the form of an axle tube for a pair of rear wheels.
  • the side carriers are I-shaped and consist of an upright leg, to which a front wheel is attached, and an adjoining rearward side leg.
  • the rear side leg is connected in its rear area to the rear cross member via a support element and a holding device.
  • the intermediate piece is accommodated in the holding device in a height-adjustable manner. In this way, a frame is obtained which, although closed, does not have sufficient rigidity due to the non-rigid connection of the support element and the holding device.
  • the object of the invention is therefore seen in to improve the wheelchair mentioned at the beginning that he has a high level of rigidity Stability and thus an improved lateral Tilting stability, so that it can be safely from severely disabled and elderly disabled can be.
  • the new wheelchair thus points like the previous one Wheelchair has a closed frame but thanks to the large mutual on the front wheel carriers Significantly spaced front wheels more stable and laterally more stable
  • Another advantage of the new wheelchair is in seeing that it gives the possibility of the front wheel carriers to be placed relatively far above the ground, so that front wheels with a relatively large diameter can be used, making driving on uneven ground and overcoming Levels is facilitated.
  • front wheels with different Diameters.
  • front wheel carriers in different positions relative to the longitudinal median plane of the wheelchair at the upright Legs of the side carrier must be attached.
  • the front wheel carriers can be parallel or oblique, each forwards or backwards, or laterally across extend to the longitudinal median plane of the wheelchair, whereby each of these arrangements also has certain advantages offers certain disadvantages.
  • the farther the front wheel carrier extend to the side the bigger they get Stability and the lateral tilt stability.
  • Front wheel carriers extending far forward increase stability.
  • a disadvantage of these arrangements but are the less easy to turn and the Danger of such protruding front wheel carrier objects touch around the wheelchair and thereby a handicap for the wheelchair movement form.
  • front wheel carriers are parallel to the median longitudinal plane or directed obliquely towards it.
  • forward directed front wheel carrier is generally the Footprint larger than with rear-facing front wheel carriers, and also the foot area protect the user against injuries, if the front wheels are the foremost and possibly form the side of the wheelchair.
  • forward and front wheel carriers directed slightly towards the longitudinal center plane you get a very large footprint as well as good turning ability and avoids colliding the front wheels with the environment, but such Front wheel carriers can be used for the arrangement of the footrest to be inconvenient. In many cases there are front wheel carriers proven that slightly backwards inward are what you can do with sufficient stability gets good turning ability and front wheel collisions avoids.
  • the front wheel carriers can with respect to their Position to the longitudinal median plane of the wheelchair also adjustable be attached.
  • the attachment should be free of play and not loosen during use.
  • this increases the weight of the wheelchair and it becomes less easy to turn because of the extra Weight at a relatively large distance from the center of gravity of the wheelchair.
  • front wheel carrier is adjustable in height attached to the upright legs of the side straps are, you also get the opportunity to vote to changing requirements front wheels with different To mount diameters.
  • the front cross member can be integral with the be made both side beams. But it did proven to be favorable to design the front cross member so that he is on both sides towards the subsequent upright leg of the side carrier extending approach, over which it is adjustable in height attached to this upright leg is.
  • the height adjustment of the front cross member is particularly necessary when on it a footrest is formed.
  • the footrest can but also on the upright legs of the side straps be attached.
  • a footrest integrated in the frame allows a foot position in which the knees of the Users are bent less and consequently the feet are placed further forward.
  • the bearings for the rear wheels are in the rear hub and are designed so that the Rear wheels in a known manner with thru-axle in angle adapter sleeves assembled and therefore easy to disassemble are.

The wheelchair (10) has a closed, three-dimensional frame (12). The latter is constituted by a front horizontal transverse support (12.1), two lateral supports (12.2, 12.3), which are arranged symmetrically in respect to the longitudinal center axis, and a rear, essentially horizontal transverse support (14). The lateral supports have the shape of a letter L with respectively an upright leg (12.2), which laterally adjoins the front transverse support (12.1), and with a rearward oriented longitudinal leg (12.3). A front wheel support (25), on which a front wheel (24) is mounted, is fastened on each upright leg (12.2) of the longitudinal supports.

Description

Gegenstand der vorliegenden Erfindung ist ein Rollstuhl.The present invention relates to a Wheelchair.

Herkömmliche Rollstühle weisen zwei Räderpaare auf, nämlich ein hinteres Räderpaar mit zwei grossen, manuell antreibbaren Hinterrädern und ein vorderes Räderpaar mit zwei wesentlich kleineren, seitlich am Rollstuhl angeordneten Vorderrädern, deren Achsen sich in einer Horizontalebene um einen Drehpunkt drehen können. Diese Rollstühle sind im allgemeinen zusammenklappbar und weisen dazu Querträger aus zwei gelenkig verbundenen Teilen auf, von denen jeder an einem Längsträger angelenkt ist. Beim Zusammenklappen dieser Rollstühle erfolgt demzufolge eine Reduktion ihrer Breite. Der Nachteil dieser zusammenklappbaren Rollstühle liegt in ihrer aufgrund der vielen gelenkigen Verbindungen mangelhaften Starrheit:Conventional wheelchairs have two pairs of wheels on, namely a rear pair of wheels with two large, manually drivable rear wheels and a front pair of wheels with two much smaller, laterally front wheels arranged on the wheelchair, their Axes in a horizontal plane around a pivot point can turn. These wheelchairs are general collapsible and have crossbars of two articulated parts, one of which everyone is articulated on a side member. When collapsing these wheelchairs are therefore made a reduction in their width. The disadvantage of this collapsible Wheelchairs are in her due to the many articulated connections deficient rigidity:

Um diesen Nachteil zu beheben, wurde versucht, Rollstühle mit starren und vorzugsweise geschlossenen Rahmen herzustellen. Durch die EP-0 887 064-A2, die einen Stand der Technik nach Artikel 54(3) EPÜ bildet, wird beispielsweise ein Rollstuhl der eingangs genannten Art beschrieben; dessen Rahmen geschlossen und daher verhältnismässig starr ist. Dieser Rahmen besteht aus einem vorderen horizontalen Querträger in Fusshöhe des Benutzers, einem hinteren horizontalen Querträger, welcher durch ein Achsrohr des Hinterradpaares gebildet ist, und zwei L-förmige Seitenträger, von welchen jeder ein Ende des vorderen Querträgers mit einem Ende des hinteren Querträgers verbindet, wobei jeder Seitenträger einen aufrechten Schenkel und einen Längsschenkel besitzt. Eine Vorderradeinrichtung mit einem einzelnen mittigen Vorderrad oder mit zwei voneinander beabstandeten Vorderrädern ist am vorderen Querträger befestigt. Dieser Rollstuhl weist eine hohe Starrheit auf und ist dank der sich im allgemeinen im mittigen Bereich des vorderen Querträgers angeordneten Vorderradeinrichtung drehfreudig und gut manövrierbar. Er wird vorwiegend als Sportrollstuhl eingesetzt. Der Nachteil dieses Rollstuhls besteht vor allem in seiner geringen Kippstabilität; er eignet sich daher weniger für den Gebrauch im Alltag und wird als ungeeignet für stark behinderte und ältere Benutzer betrachtet.
Elemente des in EP-0 887 046 A2 beschriebenen Rollstuhls sind durch eine offenkundige vorbenutzung bekannt gewerden. Diese offenkundige vorbenutzung wird als nächstliegender Stand der Technik angesehen, und bildet den Oberbegriff des Anspruchs 1.
To remedy this disadvantage, attempts have been made to produce wheelchairs with rigid and preferably closed frames. EP-0 887 064-A2, which forms part of the state of the art under Article 54 (3) EPC, describes, for example, a wheelchair of the type mentioned at the beginning; whose frame is closed and therefore relatively rigid. This frame consists of a front horizontal cross member at user height, a rear horizontal cross member which is formed by an axle tube of the rear wheel pair, and two L-shaped side members, each of which connects one end of the front cross member to one end of the rear cross member, each side carrier has an upright leg and a longitudinal leg. A front wheel device with a single central front wheel or with two spaced front wheels is attached to the front cross member. This wheelchair has a high degree of rigidity and, thanks to the front wheel device which is generally arranged in the central region of the front crossmember, is easy to turn and easy to maneuver. It is mainly used as a sports wheelchair. The main disadvantage of this wheelchair is its low stability against tipping; it is therefore less suitable for everyday use and is considered unsuitable for severely disabled and older users.
Elements of the wheelchair described in EP-0 887 046 A2 have become known through an obvious prior use. This apparent prior use is regarded as the closest prior art and forms the preamble of claim 1.

Im weiteren ist aus der EP-0 255 804-A2 ein Rollstuhl bekannt, der einen vorderen Querträger in Fusshöhe, zwei Seitenträger und einen hinteren Querträger in Form eines Achsrohres für ein Hinterradpaar besitzt. Die Seitenträger sind I-förmig und bestehen aus einem aufrechten Schenkel, an welchem ein Vorderrad befestigt ist, und aus einem daran anschliessenden rückwärts gerichteten Seitenschenkel. Der rückwärts gerichtete Seitenschenken ist in seinem hinteren Bereich über ein Stützelement und eine Haltevorrichtung mit dem hinteren Querträger verbunden. Hierbei ist das Zwischenstück höhenverstellbar in der Haltevorrichtung aufgenommen. Auf diese Weise erhält man einen Rahmen, der zwar geschlossen ist, der aber wegen der nicht-starren Verbindung von Stützelement und Haltevorrichtung dennoch keine genügende Starrheit aufweist.Furthermore, a wheelchair is known from EP-0 255 804-A2 , which has a front cross member at foot height, two side members and a rear cross member in the form of an axle tube for a pair of rear wheels. The side carriers are I-shaped and consist of an upright leg, to which a front wheel is attached, and an adjoining rearward side leg. The rear side leg is connected in its rear area to the rear cross member via a support element and a holding device. In this case, the intermediate piece is accommodated in the holding device in a height-adjustable manner. In this way, a frame is obtained which, although closed, does not have sufficient rigidity due to the non-rigid connection of the support element and the holding device.

Die Aufgabe der Erfindung wird somit darin gesehen, den eingangs genannten Rollstuhl so zu verbessern, dass er bei gleichbleibender Starrheit eine hohe Standfestigkeit und damit eine verbesserte seitliche Kippstabilität aufweist, so dass er gefahrlos auch von schwer Behinderten und älteren Behinderten benutzt werden kann.The object of the invention is therefore seen in to improve the wheelchair mentioned at the beginning that he has a high level of rigidity Stability and thus an improved lateral Tilting stability, so that it can be safely from severely disabled and elderly disabled can be.

Diese Aufgabe wird bei einem Rollstuhl der eingangs genannten Art durch die Merkmale des kennzeichnenden Teils des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen des erfindungsgemässen Rollstuhls sind durch die entsprechenden abhängigen Ansprüche umschrieben.This object is achieved in a wheelchair of the type mentioned by the features of the characterizing part of claim 1 . Advantageous further developments of the wheelchair according to the invention are described by the corresponding dependent claims.

Der neue Rollstuhl weist somit wie der vorbekannte Rollstuhl einen geschlossenen Rahmen auf, ist aber dank der an den Vorderradträgem in grossem gegenseitigen Abstand befestigten Vorderräder bedeutend standfester und seitlich kippstabilerThe new wheelchair thus points like the previous one Wheelchair has a closed frame but thanks to the large mutual on the front wheel carriers Significantly spaced front wheels more stable and laterally more stable

Ein weiterer Vorteil des neuen Rollstuhls ist darin zu sehen, dass er die Möglichkeit gibt, die Vorderradträger relativ weit über dem Boden anzuordnen, so dass Vorderräder mit verhältnismässig grossem Durchmesser verwendet werden können, wodurch das Fahren auf unebenem Untergrund und das Überwinden von Stufen erleichtert wird.Another advantage of the new wheelchair is in seeing that it gives the possibility of the front wheel carriers to be placed relatively far above the ground, so that front wheels with a relatively large diameter can be used, making driving on uneven ground and overcoming Levels is facilitated.

Je nach der Höhe, in der die Vorderradträger befestigt sind, können Vorderräder mit verschiedenen Durchmessern montiert werden.Depending on the height at which the front wheel carriers are attached, front wheels with different Diameters.

Je nach den Bedürfnissen der Benutzer können die Vorderradträger in verschiedenen Lagen relativ zur Längsmittelebene des Rollstuhls an den aufrechten Schenkeln der Seitenträger befestigt sein. Die Vorderradträger können sich parallel oder schräg, und zwar jeweils nach vorne oder hinten, oder auch seitlich quer zur Längsmittelebene des Rollstuhls erstrecken, wobei jede dieser Anordnungen gewisse Vorteile aber auch gewisse Nachteile bietet. Je weiter sich die Vorderradträger seitlich erstrecken, desto grösser werden die Standfestigkeit und die seitliche Kippstabilität. Auch weit nach vorwärts sich erstreckende Vorderradträger erhöhen die Standfestigkeit. Ein Nachteil dieser Anordnungen sind aber die geringere Drehfreudigkeit und die Gefahr, dass solche weit ragende Vorderradträger Gegenstände in der Umgebung des Rollstuhls berühren und dadurch eine Behinderung für die Rollstuhlbewegung bilden. Diese Nachteile können vermieden werden, wenn die Vorderradträger parallel zur Längsmittelebene oder schräg zu dieser hin gerichtet sind. Bei vorwärts gerichteten Vorderradträger ist generell die Standfläche grösser als bei rückwärts gerichteten Vorderradträgern, und ausserdem kann der Fussbereich des Benutzers gegen Verletzungen geschützt werden, wenn die Vorderräder den vordersten und gegebenenfalls seitlichsten Teil des Rollstuhles bilden. Damit einher gehen aber eine Verminderung der Drehfreudigkeit und eine Erschwerung der Handhabung wegen der Gefahr, mit den Vorderrädern anzustossen. Mit vorwärts und leicht zur Längsmittelebene gerichteten Vorderradträgern erhält man eine noch sehr grosse Standfläche sowie eine gute Drehfreudigkeit und vermeidet das Kollidieren der Vorderräder mit der Umgebung, aber solche Vorderradträger können für die Anordnung der Fussauflage ungünstig sein. In vielen Fällen haben sich Vorderradträger bewährt, die leicht rückwärts einwärts gerichtet sind, womit man bei noch genügender Standfestigkeit eine gute Drehfreudigkeit erhält und Vorderradkollisionen vermeidet.Depending on the needs of the users can the front wheel carriers in different positions relative to the longitudinal median plane of the wheelchair at the upright Legs of the side carrier must be attached. The front wheel carriers can be parallel or oblique, each forwards or backwards, or laterally across extend to the longitudinal median plane of the wheelchair, whereby each of these arrangements also has certain advantages offers certain disadvantages. The farther the front wheel carrier extend to the side, the bigger they get Stability and the lateral tilt stability. Also Front wheel carriers extending far forward increase stability. A disadvantage of these arrangements but are the less easy to turn and the Danger of such protruding front wheel carrier objects touch around the wheelchair and thereby a handicap for the wheelchair movement form. These disadvantages can be avoided if the front wheel carriers are parallel to the median longitudinal plane or directed obliquely towards it. At forward directed front wheel carrier is generally the Footprint larger than with rear-facing front wheel carriers, and also the foot area protect the user against injuries, if the front wheels are the foremost and possibly form the side of the wheelchair. Along with it go but a reduction in the ability to turn and aggravation of handling because of the danger to bump with the front wheels. With forward and front wheel carriers directed slightly towards the longitudinal center plane you get a very large footprint as well as good turning ability and avoids colliding the front wheels with the environment, but such Front wheel carriers can be used for the arrangement of the footrest to be inconvenient. In many cases there are front wheel carriers proven that slightly backwards inward are what you can do with sufficient stability gets good turning ability and front wheel collisions avoids.

Die Vorderradträger können bezüglich ihrer Lage zur Längsmittelebene des Rollstuhls auch einstellbar befestigt sein. Allerdings sollte dabei die Befestigung spielfrei sein und sich im Gebrauch nicht lockern. Dadurch wird allerdings das Gewicht des Rollstuhls höher und er wird weniger drehfreudig, weil sich das zusätzliche Gewicht in verhältnismässig grossem Abstand vom Schwerpunkt des Rollstuhls befindet.The front wheel carriers can with respect to their Position to the longitudinal median plane of the wheelchair also adjustable be attached. However, the attachment should be free of play and not loosen during use. However, this increases the weight of the wheelchair and it becomes less easy to turn because of the extra Weight at a relatively large distance from the center of gravity of the wheelchair.

Wenn die Vorderradträger höhenverstellbar an den aufrechten Schenkeln der Seitenträger befestigt sind, so erhält man auch die Möglichkeit, in Abstimmung an wechselnde Anforderungen Vorderräder mit verschiedenen Durchmessern zu montieren.When the front wheel carrier is adjustable in height attached to the upright legs of the side straps are, you also get the opportunity to vote to changing requirements front wheels with different To mount diameters.

Der vordere Querträger kann integral mit den beiden Seitenträgern hergestellt sein. Es hat sich aber als günstig erwiesen, den vorderen Querträger so auszubilden, dass er beidseitig einen sich in Richtung der anschliessenden aufrechten Schenkels des Seitenträgers erstreckenden Ansatz besitzt, über welchen er höhenverstellbar an diesem aufrechten Schenkel befestigt ist.The front cross member can be integral with the be made both side beams. But it did proven to be favorable to design the front cross member so that he is on both sides towards the subsequent upright leg of the side carrier extending approach, over which it is adjustable in height attached to this upright leg is.

Die Höhenverstellbarkeit des vorderen Querträgers ist insbesondere dann erforderlich, wenn an ihm eine Fussauflage gebildet ist. Die Fussauflage kann aber auch an den aufrechten Schenkeln der Seitenträger befestigt sein. Eine im Rahmen integrierte Fussauflage lässt eine Fussstellug zu, bei welcher die Knie des Benutzers weniger gebogen werden und demzufolge die Füsse weiter vorn angeordnet sind.The height adjustment of the front cross member is particularly necessary when on it a footrest is formed. The footrest can but also on the upright legs of the side straps be attached. A footrest integrated in the frame allows a foot position in which the knees of the Users are bent less and consequently the feet are placed further forward.

Die Lager für die Hinterräder befinden sich in der Hinterradnabe und sind so ausgebildet, dass die Hinterräder in bekannter Weise mit Steckachser in Winkeladapterhülsen montiert und dadurch leicht demontierbar sind. Im montierten Zustand sind die Winkeladapterhülsen für die Achsen der Hinterräder, die im allgemeinen als Steckachsen ausgebildet sind, quer zur Fahrtrichtung und seitlich leicht aufwärts gerichtet, damit die Räder, wie bei Rollstühlen üblich, unter einem gewissen Radsturz angeordnet sind. Um die Spurparallelität der Hinterräder genau einzustellen, kann der hintere Querträger, mit den in ihm befestigten Winkeladapterhülsen, gedreht werden, bis es diejenige Lage einnimmt, in der die Winkeladapterhülsen korrekt gerichtet sind, seine richtige Lage einnimmt; zu diesem Zweck kann am hinteren Querträger eine Wasserwaage eingebaut sein. Der winkelmässige Radsturz richtet sich einerseits nach den Abmessungen des Rollstuhls und anderseits nach dem jeweiligen Verwendungszweck des Rollstuhls und ist daher vorzugsweise veränderbar. Erfindungsgemäss ist der Einbau eines Paares von einstellbaren Winkeladapterhülsen. Vorteilhaft kann der Radsturz mittels solcher einstellbaren Winkeladapterhülsen nach der Erfindung zwischen 0° und etwa 15° verändert werden.The bearings for the rear wheels are in the rear hub and are designed so that the Rear wheels in a known manner with thru-axle in angle adapter sleeves assembled and therefore easy to disassemble are. The angle adapter sleeves are in the assembled state for the axles of the rear wheels, which in general are designed as thru axles, across Direction of travel and slightly upwards to the side so that the wheels, as usual with wheelchairs, under one certain camber are arranged. To track parallelism the rear wheels can be adjusted precisely rear crossmember, with the angle adapter sleeves fixed in it, be rotated until it's that location occupies in the right angle adapter sleeves are in its correct position; to this A spirit level can be used on the rear crossmember be installed. The angular camber is aligned on the one hand according to the dimensions of the wheelchair and on the other hand according to the respective purpose of the wheelchair and is therefore preferably changeable. According to the invention, the installation of a pair of adjustable Angle adapter sleeves. The camber can be advantageous by means of such adjustable angle adapter sleeves according to the invention between 0 ° and about 15 ° can be changed.

In neuerer Zeit werden Rollstühle vorzugsweise so konzipiert, dass sie sich zusammen mit einem sogenannten Bike verwenden lassen. Ein Bike ist eine Einrichtung mit einem Frontrad, einem Antrieb und einer Lenkung. Der Rollstuhl wird an das Bike angehängt und bildet zusammen mit dem Bike eine antreibbare Einheit. Diese Einheit läuft auf drei Rädern, nämlich dem Rad des Bikes, welches ein vorne angeordnetes Triebrad bildet, und den Hinterrägem des Rollstuhls, welche hinten angeordnete Laufräder bilden. Beim Ankoppeln des Rollstuhles wird dieser leicht nach hinten gekippt, so dass sein Vorderrad bzw. seine Vorderräder keinen Bodenkontakt mehr haben. Diese Anordnung ist allerdings bei Rollstühlen herkömmlicher Konzeption mit einem gewissen Nachteil behaftet, nämlich mit der Tendenz des Rollstuhls und damit der Einheit, nach hinten zu kippen. Um einen Rollstuhl mit angehobenenem Vorderrad bzw. angehobenen Vorderrädem mit einem Bike zu koppeln, ohne dass die Gefahr des Rückwärtskippens besteht, kann der Radstand, das heisst der gegenseitige Abstand der Vorderachse des Bikes und des Hinterradpaares des Rollstuhls, vergrössert. Zu diesem Zwecke werden die Hinterräder und ihre Befestigung so gestaltet, dass die Hinterräder zwischen einer vorderen Lage, in der sie sich bei der Verwendung des Rollstuhls ohne Bike befinden, und einer hinteren Lage, in der der Rollstuhl weniger kippgefährdet und damit biketauglich ist, verschieben lassen. Die Vergrösserung des Radstandes kann beispielsweise dadurch erreicht werden, dass die hinteren Enden der Längsschenkel ein sich rückwärts erstreckendes Verlängerungsteil aufweisen, an welchem der hintere Querträger bzw. das Achsrohr in verschiedenen Lagen befestigt werden kann. Bei Verwendung des Rollstuhls ohne Bike wirken die unter der Sitzfläche angeordneten Verlängerungsteile nicht störend. Der Radstand kann zwecks Verbesserung der Kippsicherheit natürlich auch vergrössert werden, ohne dass der Rollstuhl mit einem Bike gekoppelt wird, allerdings muss dabei eine Verschlechterung der Manövrierbarkeit in Kauf genommen werden.In recent times, wheelchairs are preferred designed to work together with a so-called Have your bike used. A bike is an institution with a front wheel, a drive and one Steering. The wheelchair is attached to the bike and forms a drivable unit together with the bike. This unit runs on three wheels, namely the wheel of the bike, which forms a front wheel, and the back of the wheelchair, which is in the back form arranged impellers. When connecting the The wheelchair is tipped back slightly, so that his front wheel or his front wheels have no ground contact have more. However, this arrangement is for conventional wheelchairs with one certain disadvantage, namely with the tendency of the wheelchair and thus the unit to tip backwards. To a wheelchair with the front wheel raised or to raise the front wheels to a bike, without the risk of tipping backwards can the wheelbase, that is the mutual Distance between the front axle of the bike and the rear wheel pair of the wheelchair, enlarged. For this purpose the rear wheels and their attachment are designed so that the rear wheels between a front position in which they are using the wheelchair without Bike, and a rear position in which the wheelchair less risk of tipping and therefore suitable for biking, let it move. The enlargement of the wheelbase can be achieved, for example, by the rear ends of the longitudinal legs face backwards have extending extension part which the rear crossmember or the axle tube in different layers can be attached. When using the wheelchair without a bike, those arranged under the seat seem to be working Extension parts not disturbing. The wheelbase can to improve tipping safety, of course be enlarged without the wheelchair with one Bike is coupled, however, must deteriorate maneuverability become.

Die Sitzfläche des Rollstuhls befindet sich zwischen den Längsschenkeln der Seitenträger und kann an diesen befestigt sein. Die Sitzfläche ist an zwei zusätzlichen Sitzlängsträgern befestigt, und die nach hinten gerichteten Längsschenkel der Seitenträger sind leicht nach unten gerichtet. An diesen geneigten Längsschenkeln sind die Sitzlängsträger so befestigt, dass sie vorne um einen Punkt der Längsschenkel schwenkbar sind und hinten einen verstellbaren Abstand von den Längsschenkeln haben. Zu diesem Zwecke ist eine Sitzstrebenvorrichtung angeordnet; diese weist zwei Sitzstreben auf, von denen jede schwenkbar an einem Drehpunkt an einem der Sitzlängsträger befestigt ist und in wählbarer wirksamer Sitzstrebenlänge am Längsschenkel des Seitenträgers des Rahmens befestigt ist. Beidseitig unterhalb des Sitzes bilden somit der Längsschenkel, der Sitzlängsträger und die Sitzstrebe je ein Dreieck in einer Vertikalebene. Die maximale Neigung nach hinten unten, die der Sitz einnehmen kann, ist durch die Neigung der Längsschenkel des Seitenträgers bestimmt, und die maximale Neigung nach vorne unten, die der Sitz einnehmen kann, ist durch die Länge der Sitzstreben bestimmt. Obwohl auch längenverstellbare Sitzstreben, gegebenenfalls mit fluidbetätigte Zylinder/Kolben-Einrichtungen oder mit Spindeln, verwendet werden könnten, wird eine einfache Ausführungsform des Rollstuhls nach der Erfindung so ausgebildet, dass die Sitzstreben über ihre Länge eine Vielzahl von Bohrungen aufweisen. Je nach gewählter Sitzneigung werden zwei Schrauben durch zwei im gleichen Abstand von den Drehpunkten befindliche Bohrungen geführt, mittels welchen die Sitzstreben an den zugehörigen Längsschenkeln befestigt sind. Zur Stabilisierung hat es sich als vorteilhaft erwiesen, die beiden Sitzstreben mittels einer Querstangenanordnung zu parallelisieren. Vorzugsweise sind mehrere mögliche Befestigungspunkte der Sitzlängsträger an den vorderen Enden der Längsschenkel der Seitenträger des Rahmens in Längsrichtung vorgesehen.The seat of the wheelchair is between the longitudinal legs of the side beams and can be attached to this. The seat is attached to two additional ones Seat side straps attached, and the rearward facing Longitudinal legs of the side beams are light directed downwards. On these inclined longitudinal legs the seat rails are attached so that they are in the front are pivotable about a point of the longitudinal leg and at the back an adjustable distance from the longitudinal legs to have. For this purpose is a seat stay device arranged; this has two seat stays on, each of which pivots at a pivot point is attached to one of the seat side members and in selectable effective seat stay length on the longitudinal leg the side member of the frame is attached. The longitudinal leg thus forms on both sides below the seat, the seat side member and the seat stay each Triangle in a vertical plane. The maximum slope towards the bottom, which the seat can take up due to the inclination of the longitudinal legs of the side carrier determined, and the maximum forward tilt below that the seat can take is by length the seatstay determines. Although also adjustable in length Seat stays, possibly with fluid-operated cylinder / piston devices or with spindles could be a simple embodiment of the wheelchair designed according to the invention that the seat stays have a variety of lengths Have holes. Depending on the selected seat angle are two screws by two at the same distance bores from the fulcrums, by means of which the seat stays on the associated Longitudinal legs are attached. For stabilization it has proven advantageous to use the two seat stays parallelize by means of a crossbar arrangement. Preferably there are several possible attachment points the seat side member at the front ends the longitudinal leg of the side member of the frame provided in the longitudinal direction.

In einer besonders günstigen Ausführungsform des erfindungsgemässen Rolllstuhls wird der Sitz mit den beiden Sitzlängsträgem durch einen Teil eines vom Rahmen entfernbaren Sitzmoduls gebildet.In a particularly favorable embodiment the wheelchair according to the invention becomes the seat with the two longitudinal seats by part of one formed from the frame removable seat module.

Das Sitzmodul umfasst üblicherweise neben dem eigentlichen Sitz einen Rücken, wobei vorzugsweise nur der Sitz am Rahmen des Rollstuhls befestigt ist, während der Rücken seinerseits am Sitz montiert ist, und zwar bevorzugt so, dass der Winkel zwischen Sitz und Rücken verstellbar ist, am besten so weit, dass der Rücken auf den Sitz abgeklappt werden kann, um das Transportvolumen des Rollstuhls zu verringern.The seat module usually includes in addition the actual seat a back, preferably only the seat is attached to the frame of the wheelchair, while the back is in turn attached to the seat, preferably so that the angle between the seat and back is adjustable, preferably so far that the Back on the seat can be folded to the Reduce the transport volume of the wheelchair.

In einem solchen Sitzmodul sind die Sitzlängsträger zur Erhöhung der Stabilität vorzugsweise durch mindestens einen Sitzquerträger verbunden, und in einer besonders geeigneten Ausführungsform bilden die Sitzlängsträger und ein hinten angeordneter Sitzquerträger einen U-förmigen Sitzrahmen, der durch einen weiteren, in seinem vorderen Bereich vorgesehenen, nach unten ausgewölbten Sitzverstärkungsträger verstärkt werden kann. Da der Rollstuhl trotz der beschriebenen Möglichkeit des Umklappens des Rückens kein unter Breitenverminderung zusammenklappbarer Klapprollstuhl ist, kann die Sitzfläche starr sein. Vorzugsweise wird aber auch beim vorliegenden breitenfesten Rollstuhl nach der Erfindung für die Sitzfläche ein flexibles Material wie beispielsweise ein Gewebeabschnitt, verwendet, auf dem im allgemeinen ein austauschbares Sitzkissen liegt. Ein als Keilkissen ausgebildetes Sitzkissen erlaubt eine weitere Einflussnahme auf die Neigung des Sitzes.The seat side members are in such a seat module preferably to increase stability connected at least one seat cross member, and in one particularly suitable embodiment form the Seat side member and a rear seat cross member a U-shaped seat frame through a further, provided in its front area, Reinforced seat reinforcement beam arched downwards can be. Because the wheelchair despite the described Possibility of folding the back no collapsible with reduced width Folding wheelchair, the seat can be rigid. Preferably but is also in the present broad-based Wheelchair according to the invention for the seat flexible material such as a fabric section, used on the generally a replaceable Seat cushion lies. One designed as a wedge pillow Seat cushion allows further influence on the inclination of the seat.

Das Sitzmodul umfasst, wie schon erwähnt, den soeben beschriebenen Sitz sowie den Rücken, der am Sitz befestigt ist, ohne unmittelbar mit dem Rahmen des Rollstuhls verbunden zu sein. In einer bevorzugten Ausbildung weist der Rücken zwei seitliche, meist rohrförmige Rückenstützen auf, deren untere Enden über Winkelplatten am hinteren Bereich der Sitzlängsträger befestigt sind; eine gewisse Einstellbarkeit kann erreicht werden, indem für die Befestigung der Winkelplatten verschiedene Bohrungen, sei es in den Winkelplatten und/oder in den Sitziängsträgern und/oder in den Rükkenstützen vorgesehen werden.As already mentioned, the seating module includes the seat just described and the back, the is attached to the seat without being directly to the frame of being connected to the wheelchair. In a preferred one Training, the back has two lateral, mostly tubular Back supports on, whose lower ends over Angle plates on the rear area of the side rails are attached; a certain adjustability can be achieved be made by for fixing the angle plates different holes, be it in the angle plates and / or in the seat side members and / or in the back supports be provided.

Soll zur Verkleinerung des Transportvolumens des Rollstuhls der Rücken auf den Sitz abklappbar sein, so werden die Winkelplatten so befestigt, dass sie sich um ihre beiden Befestigungsachsen am Sitzlängsträger und an der Rückenstütze drehen können. Um dennoch beim Gebrauch des Rollstuhls den Rücken relativ zum Sitz zu fixieren, sind zwei seitliche Fixierplatten vorgesehen, die fest an den Sitzlängsträgern befestigt sind und die schlitzförmige Durchbrüche enthalten, durch welche Zapfen der Rückenstützen ragen. Die Fixierplatten bilden, wenn der Rücken nicht auf den Sitz geklappt ist, Winkelstreben zwischen den Sitzlängsträgern und den Rückenstützen. Die Durchbrüche weisen an ihren hinteren Enden quer zu ihnen ünd bei nicht abgeklapptem Rücken nach oben gerichtete Rastöffnungen für die Zapfen auf. Die leicht elastischen Fixierplatten sind an ihren hinteren Enden durch eine Kordel verbunden. Ein Aufwärtszug an der Kordel bewirkt das Ausrasten der Zapfen aus den Rastöffnungen und erlaubt das Abklappen des Rücken auf den Sitz. Die Fixierplatten sind mittels Schrauben an den Sitzlängsträgern befestigt; um eine wahlweise Befestigung in verschiedenen Stellungen zu ermöglichen, können sie anstelle einer einzigen Bohrung mehrere nebeneinanderliegende Bohrungen für die Schrauben enthalten.To reduce the transport volume the back of the wheelchair can be folded down onto the seat, so the angle plates are attached so that they are around their two fastening axes on the seat side member and can turn on the back support. To still when using the wheelchair the back relative to To fix the seat, two side fixing plates are provided, which are firmly attached to the seat side members and which contain slit-shaped openings, through which pins of the back supports protrude. The fixing plates form when the back is not folded on the seat is, angle struts between the seat rails and the back supports. The breakthroughs point to theirs rear ends transverse to them and when not folded down Back upward locking openings for the Cones on. The slightly elastic fixing plates are on their rear ends connected by a cord. On Upward pull on the cord causes the Pin out of the locking openings and allows folding of the back on the seat. The fixing plates are by means of Screws attached to the seat side members; around an optional attachment in different positions to enable them instead of a single one Drilling several adjacent holes included for the screws.

Die Fixierplatten können auch zur Befestigung von seitlichen Kleiderschutzplatten benutzt werden, die an den Fixierplatten angeschraubt werden können, oder zur Befestigung eines Radspritzschutzes. Vorzugsweise wird der Radspritzschutz so ausgebildet, dass er an seiner dem Benutzer abgewandten Fläche eine leicht federnde, in verschiedenen Stellungen montierbare Radschutzbride besitzt, so dass der Radspritzschutz werkzeuglos auf die Fixierplatte oder gegebenenfalls auf die Kleiderschutzplatte aufsteckbar ist, so dass im montierten Zustand die Fixierplatte oder die Kleiderschutzplatte zwischen dem eigentlichen Spritzschutzteil und der Radschutzbride eingeklemmt ist.The fixing plates can also be used for fastening of side clothing protection plates that are used can be screwed to the fixing plates, or for attaching a wheel splash guard. Preferably the wheel splash guard is designed so that it is on its surface facing away from the user is easy resilient, mountable in different positions Has wheel guard, so the wheel splash guard without tools on the fixing plate or if necessary is attachable to the protective clothing plate, so that in assembled the fixing plate or the clothing protection plate between the actual splash guard and the wheel guard is jammed.

Obwohl man zur Einsparung von Gewicht beim Rückenteil auf Querträger verzichten kann, werden vorzugsweise die beiden seitlichen Rückenstützen durch einen nach hinten ausgebogene Querträger verbunden. Dieser kann gleichzeitig als Griff zum Schieben des Rollstuhls durch eine Drittperson dienen und erleichtert das Ausüben des eben erwähnten Kordelzuges, wenn mit der gleichen Hand die Querstange und die Kordel erfasst werden.Although saving weight can do without cross members on the back preferably the two side back supports connected by a cross beam bent backwards. This can also be used as a handle for pushing serve the wheelchair by a third party and make it easier practicing the drawstring just mentioned, if with the same hand the cross bar and the cord is grasped.

Zum Schieben des Rollstuhis können auch an den oberen Enden der Rückenträger demontierbare Schiebegriffe befestigt sein, die vorzugsweise höhenverstellbar sind.You can also push the wheelchair the upper ends of the back straps can be removed Push handles can be attached, preferably adjustable in height are.

Zur Bildung einer Fläche für den Rücken kann, wie beim Sitz, ein starres Material oder ein Gewebeabschnitt vorgesehen sein. Um einen einstellbaren und damit an den Benutzer des Rollstuhls anpassbaren Rücken zu erhalten, ist es aber vorteilhaft, die Rückenstützen durch ein breites oder, was eine individuellere Anpassung ermöglicht, mehrere schmale längenverstellbare flexible Bandpaare zu verbinden.To form an area for the back, like the seat, a rigid material or a section of fabric be provided. To get an adjustable and adaptable to the user of the wheelchair To get back, it is advantageous to use the back supports by a broad or what a more individual Adjustment allows multiple narrow length adjustable to connect flexible pairs of bands.

Um den Sitzkomfort zu verbessern, kann der Rücken ferner mit einem Rückenkissen versehen sein. Ein solches Rückenkissen kann beispielsweise zwei zusammenhängende, vorne und hinten an der Verbindung der Rückenträger anliegende Rückenkissenteile aufweisen und von oben über die Verbindung der Rückenträger gestülpt werden. Es sind aber auch anders geformte Rückenkissen, beispielsweise mit nur einem Rückenkissenteil, möglich.To improve seating comfort, the Back also be provided with a back cushion. Such a back cushion can, for example, two connected, at the front and back of the connection the back support has adjacent back cushion parts and from above via the connection of the back straps be put over. But they are also shaped differently Back cushions, for example with only one Back cushion part, possible.

Damit das Rückenkissen auch bei Bewegungen des Benutzers in seiner Lage bleibt, und damit sich das Sitzkissen nicht zwischen der Sitzfläche und dem Rücken nach hinten entfernt, kann am vorderen Teil des Rückenkissens unten ein textiler Rückenkissenlappen angesetzt sein, der zwischen das Gewebe der Sitzfläche und das Sitzkissen zu liegen kommt.So that the back cushion also during movements of the user remains in his position, and thus himself the seat cushion is not between the seat and the Back removed back, can be on the front part of the Back cushion below a textile back cushion rag be attached between the fabric of the seat and the seat cushion comes to rest.

Das Rückenkissen kann an seinem hinteren Teil auch eine Tasche aufweisen.The back cushion can be on its back Part also have a pocket.

Beim neuen Sitzmodul müssen vielerorts zwei Gewebeteile aneinander befestigt werden, wobei diese Befestigungen vorzugsweise lösbar und gegebenenfalls in kleinen Bereichen einstellbar sein sollten; das Sitzkissen muss auf der Sitzfläche befestigt werden, die beiden Teile des Rückenkissen müssen gegenseitig und/oder an den die Rückenstützen verbindenden Teilen befestigt werden, und jeweils zwei Bänder eines der Bandpaare, die die Rückenstützen verbinden, müssen gegenseitig befestigt werden.

Der in den Fig. 1, 2A und 2B dargestellte Rollstuhl 10 weist einen Rahmen 12 auf, der durch einen vorderen horizontalen Querträger 12.1, zwei symmetrisch zu seiner Längsmittelachse angeordnete Seitenträger 12.2, 12.3 sowie durch einen hinteren, im wesentlichen horizontalen Querträger 14 gebildet wird. Die Seitenträger weisen die Form eines L auf, mit einen aufrechten Schenkel 12.2 einem oben an diesen anschliessenden rückwärts gerichteten Längsschenkel 12.3 etwa in Sitzhöhe. Die aufrechten Schenkel 12.2 sind jedoch im allgemeinen nicht genau senkrecht sondern leicht nach hinten geneigt, und sie werden üblicherweise durch ein nicht dargestelltes Wadenband verbunden. Der vordere Querträger 12.1 befindet sich um ein Weniges über dem Boden, also etwa in Fusshöhe eines Benutzers. Der hintere Querträger 14 wird durch ein Achsrohr für ein Hinterradpaar mit zwei Rädern 18 des Rollstuhls gebildet, wobei zur Verbindung des Achsrohres 14 mit den hinteren Enden der Längsschenkel 12.3.der Seitenträger Achshaltereinrichtungen 16 dienen. Die Seitenträger 12.2, 12.3 und der vordere Querträger 12.1 sind im allgemeinen aus gebogenem rohrförmigem Material hergestellt.The wheelchair 10 shown in FIGS. 1, 2A and 2B has a frame 12 which is formed by a front horizontal cross member 12.1, two side members 12.2, 12.3 arranged symmetrically to its longitudinal central axis and by a rear, essentially horizontal cross member 14 . The side supports have the shape of an L, with an upright leg 12.2 and a rearward-facing longitudinal leg 12.3 adjoining the top at about the seat height. However, the upright legs 12.2 are generally not exactly vertical but slightly inclined backwards, and they are usually connected by a calf band, not shown. The front cross member 12.1 is located a little above the floor, that is to say at about a user's foot level. The rear crossmember 14 is formed by an axle tube for a pair of rear wheels with two wheels 18 of the wheelchair, the axle supports 16 serving to connect the axle tube 14 to the rear ends of the longitudinal legs 12.3 . The side beams 12.2, 12.3 and the front cross beam 12.1 are generally made of bent tubular material.

Der vordere Querträger 12.1 ist beidseits um etwa 90° abgebogen oder weist entsprechend gerichtete Ansätze 12.4 auf, welche sich in Richtung der benachbarten aufrechten Schenkel 12.2 der Seitenträger erstrecken und höhenverstellbar an diesen befestigt sind; im vorliegenden Ausführungsbeispiel ragen die abgebogenen Enden des Querträgers 12.1 in diese aufrechten Schenkel 12.2, es wäre aber auch die umgekehrte Anordnung denkbar, in welcher die unteren Enden der Schenkel 12.2 in die entsprechend gerichteten abgebogenen Enden 12.4 des Querträgers 12.1 hineinragen würden.The front cross member 12.1 is bent on both sides by approximately 90 ° or has correspondingly directed lugs 12.4 which extend in the direction of the adjacent upright legs 12.2 of the side members and are attached to them in an adjustable manner; In the present exemplary embodiment, the bent ends of the cross member 12.1 protrude into these upright legs 12.2, but the reverse arrangement would also be conceivable, in which the lower ends of the legs 12.2 would protrude into the correspondingly directed bent ends 12.4 of the cross member 12.1 .

Die Hinterräder 18 sind seitlich mittels in den Fig. 3A, 3B, 4A, 4B dargestellten Winkeladapterhülsen 20.1 bzw. 20.2 bzw. 22 am Achsrohr bzw. am hinteren Querträger 14 befestigt. Jede Winkeladapterhülse 20.1 bzw. 20.2 bzw. 22, die mit einem Teil ihrer Länge in eines der offenen Enden de hinteren Querträgers 14 eingepresst ist und mit ihrer restlichen Länge aus dem hinteren Querträger 14 hinausragt, bildet ein Lager für eine in ihr aufgenommene, nicht dargestellte Steckachse, mit welcher ein Hinterrad 18 befestigt ist. Um den Radsturz zu verändern, muss entweder die für einen bestimmten Radsturz gefertigte Winkeladapterhülse 20.1 gemäss Fig. 3A gegen eine für einen anderen Radsturz gefertigte Winkeladapterhülse 20.2 gemäss Fig. 3B ausgetauscht werden, oder es wird eine verstellbare Winkeladapterhülse 22 gemäss Fig. 4A und Fig. 4B verwendet.The rear wheels 18 are laterally fastened to the axle tube or to the rear cross member 14 by means of angle adapter sleeves 20.1 or 20.2 or 22 shown in FIGS . 3A, 3B, 4A, 4B . Each angle adapter sleeve 20.1 or 20.2 or 22 de with a part of its length in one of the open ends of the rear cross member is pressed 14 and protrudes with its remaining length of the rear cross member 14 forms a bearing for a received therein, not shown Thru axle with which a rear wheel 18 is attached. In order to change the wheel camber, either the angle adapter sleeve 20.1 manufactured according to FIG. 3A for a specific wheel camber must be exchanged for an angle adapter sleeve 20.2 manufactured according to FIG. 3B for another wheel camber, or an adjustable angle adapter sleeve 22 according to FIGS. 4A and 4B. 4B used.

Die in Fig. 3A dargestellte Winkeladapterhülse ergibt einen minimalen Radsturz von 0°, und die in Fig. 3B dargestellte Winkeladapterhülse ergibt einen Radsturz im Bereich von ca. 15°, was bei dieser Konstruktion der Winkeladapterhülse etwa dem maximalen Wert entspricht.The angle adapter sleeve shown in FIG. 3A results in a minimum camber of 0 °, and the angle adapter sleeve shown in FIG. 3B results in a camber in the range of approximately 15 °, which corresponds approximately to the maximum value in this construction of the angle adapter sleeve.

Die Fig. 4A und 4B zeigen dieselbe verstellbare Winkeladapterhülse 22 in zwei verschiedenen Einstellungen, wobei der Radsturz mit einer Einstellung gemäss Fig. 4A etwa 1° und mit einer Einstellung gemäss Fig. 4B etwa 10° beträgt. Die Winkeladapterhülse 22 weist einen zylindrischen Teil 22.1 mit einer Lagerbohrung 22.2 und einen asymmetrischen, schräg zur Achse der Lagerbohrung 22.2 gerichteten Ansatz 22.3 auf. Der zylindrische Teil 22.1 verläuft durch einen Lagerzylinder 22.4, der drehbar über ein Achsrohr-Einsatzstück 22.5 im hinteren Querträger bzw. Achsrohr 14 gelagert ist. Der asymmetrische Ansatz 22.3 ist über ein weiteres Achsrohr-Einsatzstück 22.6 und eine Querwelle 22.7 im hinteren Querträger bzw. Achsrohr 14 abgestützt. Ein Stempel 22.8, der über einen Exzenterhebel 22.9 betätigbar ist, drückt in montierter Stellung den asymmetrischen Ansatz 22.3 gegen die Kraft einer Feder nach unten. Durch eine Schwenkung des Exzenterhebels 22.9 entfernt sich der Stempel 22.8 unter der Kraft der Feder vom exzentrischen Ansatz 22.3, so dass die Winkeladapterhülse 22 in eine andere Stellung gebracht werden kann, in welcher sie durch erneute Drehung des Exzenterhebeis 22.9 in dieser neuen Stellung wieder fixiert wird. 4A and 4B show the same adjustable angle adapter sleeve 22 in two different settings, the wheel camber being approximately 1 ° with a setting according to FIG. 4A and approximately 10 ° with a setting according to FIG. 4B . The angle adapter sleeve 22 has a cylindrical part 22.1 with a bearing bore 22.2 and an asymmetrical extension 22.3 directed obliquely to the axis of the bearing bore 22.2 . The cylindrical part 22.1 runs through a bearing cylinder 22.4 which is rotatably mounted in the rear cross member or axle tube 14 via an axle tube insert 22.5 . The asymmetrical extension 22.3 is supported by a further axle tube insert 22.6 and a cross shaft 22.7 in the rear cross member or axle tube 14 . A plunger 22.8, which can be actuated via an eccentric lever 22.9 , presses the asymmetrical extension 22.3 downward against the force of a spring in the mounted position. By pivoting the eccentric lever 22.9 , the plunger 22.8 moves away from the eccentric extension 22.3 under the force of the spring, so that the angle adapter sleeve 22 can be brought into another position in which it is fixed in this new position again by rotating the eccentric lever 22.9 ,

Damit die Spuren der Hinterräder 18 parallel zur Fahrtrichtung bzw. zur Längsmittelebene des Rollstuhls 10 verlaufen, muss der hintere Querträger 14 bzw. das Achsrohr mit den eingepressten Winkeladaptern 20.1, 20.2 bzw. 22 so eingestellt sein, dass sich die Lager und damit die nicht dargestellten Steckachsen der Hinterräder 18, die entsprechend dem gewünschten Radsturz nach aussen leicht aufwärts gerichtet sein müssen, genau in einer Querebene zur Längsmittelebene des Rollstuhls 10 befinden. Zur Einstellung der Winkeladapterhülsen bzw. des hinteren Querträgers 14 ist am letzteren eine nicht dargestellte Wasserwaage angebracht.So that the traces of the rear wheels 18 run parallel to the direction of travel or to the longitudinal median plane of the wheelchair 10 , the rear cross member 14 or the axle tube with the pressed-in angle adapters 20.1, 20.2 or 22 must be set so that the bearings and thus the ones not shown Thru axles of the rear wheels 18 , which must be directed slightly upwards in accordance with the desired camber, are located exactly in a transverse plane to the longitudinal center plane of the wheelchair 10 . To adjust the angle adapter sleeves or the rear cross member 14 , a spirit level, not shown, is attached to the latter.

Die Hinterräder 18 sind in üblicher Weise mittels an ihnen befestigten, zu ihnen konzentrischen Greifringen 19 manuell antreibbar.The rear wheels 18 can be manually driven in the usual way by means of gripping rings 19 attached to them and concentric with them.

Zwei nicht antreibbare Vorderräder 24 eines Vorderradpaares sind drehbar an Vorderradträgem 25 montiert, welche an den aufrechten Schenkeln 12.2 der Seitenträger befestigt sind. Der Durchmesser der Vorderräder 24 ist wie üblich bedeutend kleiner ist als der Durchmesser der Hinterräder 18, jedoch können bei genügend hoch angeordneten Vorderradträgem 25 die Vorderräder 24 einen verhältnismässig grossen Durchmesser aufweisen. Jedes Vorderrad 24 ist in einer Gabel 26 gelagert. Die Gabel 26 weist an ihrem oberen Ende einen vertikalen Drehzapfen auf, der drehbar in einem Zapfenlager 28 aufgenommen ist, welches über den Vorderadträger 25 am aufrechten Schenkel 12.2 befestigt ist.. Der Vorderadträger 25 ist nach rückwärts und zur Längsmittelebene des Rollstuhls 10 gerichtet. Die beiden Enden der Gabel 26 weisen für die Aufnahme einer Vorderradachse 32 paarweise Bohrungen 33 in zwei oder mehr Höhen auf, so dass das Vorderrad 24 in verschiedenen Höhen eingebaut werden kann, wodurch die Neigung des gesamten Rollstuhls 10 verändert werden kann. Eine weitere Möglichkeit zur Veränderung der Neigung des gesamten Rollstuhls 10 erhält man durch den Einbau kleinerer oder grösserer Vorderräder 24. Two non-drivable front wheels 24 of a pair of front wheels are rotatably mounted on front wheel carriers 25 , which are fastened to the upright legs 12.2 of the side carriers. The diameter of the front wheels 24 is, as usual, significantly smaller than the diameter of the rear wheels 18, but the front wheels 24 can have a relatively large diameter if the front wheel carriers 25 are arranged high enough. Each front wheel 24 is supported in a fork 26 . The fork 26 has at its upper end a vertical pivot which is rotatably received in a journal bearing 28 which is fastened to the upright leg 12.2 via the front wheel carrier 25. The front wheel carrier 25 is directed backwards and towards the longitudinal center plane of the wheelchair 10 . The two ends of the fork 26 have bores 33 in pairs at two or more heights for receiving a front wheel axle 32 , so that the front wheel 24 can be installed at different heights, as a result of which the inclination of the entire wheelchair 10 can be changed. Another possibility for changing the inclination of the entire wheelchair 10 is obtained by installing smaller or larger front wheels 24.

Fig. 5 zeigt eine Fussauflage 40, die im wesentlichen aus einem am vorderen Querträger 12.1 befestigten Bügel 42 zum Abstellen der Füsse des Benutzers besteht; durch die Höhenverstellbarkeit des Querträgers 12.1 relativ zu den aufrechten Schenkeln 12.2 der Seitenträger kann die Höhe der Fussauflage 40 eingestellt werden. Fig. 5 shows a footrest 40 , which consists essentially of a bracket 42 attached to the front cross member 12.1 for parking the user's feet; the height of the cross member 12.1 relative to the upright legs 12.2 of the side members allows the height of the footrest 40 to be adjusted.

Fig. 6 zeigt eine anders ausgebildete Fussauflage 40, die durch einen an den aufrechten Teilen der Seitenträger seitlichen Träger 12.2 höhenverstellbar befestigten U-förmigen Teil 44 mit einem bügelartigen Ansatz 46 gebildet ist. 6 shows a differently designed footrest 40 , which is formed by a U-shaped part 44 with a bow-like extension 46, which is attached to the upright parts of the side supports 12.2 in a height-adjustable manner.

Der Rollstuhl 10 weist ferner eine Bremsvorrichtung auf, die durch zwei Bremseinheiten 34 gebildet ist. Die Bremseinheiten sind gegengleich ausgebildet und spiegelsymmetrisch am vorderen Bereich der Längsträger 12.3 befestigt. Die Fig. 7 bis 9 zeigen drei verschiedene, an sich bekannte Ausführungsformen einer Bremseinheit 34 bzw. 36 bzw. 38 und bedürfen keiner weiteren Erklärung.The wheelchair 10 also has a braking device which is formed by two braking units 34 . The brake units are of opposite design and mirror-symmetrically fastened to the front area of the longitudinal beams 12.3 . 7 to 9 show three different, known embodiments of a brake unit 34 or 36 or 38 and need no further explanation.

In Fig. 10 ist ein Sitzmodul 50 dargestellt. Dieses Sitzmodul 50 besteht im wesentlichen aus einem Sitz 52 und aus einem Rücken 54. 10 shows a seat module 50 . This seat module 50 essentially consists of a seat 52 and a back 54 .

Der Sitz 52 weist zwei parallele Sitzlängsträger 56 auf, welche zusammen mit einem rückwärtigen, in Fig. 13 sichtbaren Sitzquerträger 58 einen U-förmigen, aus einem entsprechend gebogenen Rohr hergestellten Sitzrahmen bilden, der durch einen weiteren, nach unten gewölbten, in Fig. 13 teilweise sichtbaren Sitzquerträger 60 verstärkt ist. Zwischen den Sitzlängsträgern 56 ist mittels mehrerer Schrauben 62 ein Abschnitt eines textilen Materials befestigt, das im wesentlichen die Sitzfläche 64 bildet, und auf welchem ein nicht dargestelltes Sitzkissen angeordnet ist.The seat 52 has two parallel seat longitudinal members 56 which, together with a rear seat cross member 58 visible in FIG. 13 , form a U-shaped seat frame made from a correspondingly bent tube, which is curved in FIG. 13 by a further, curved downward partially visible seat cross member 60 is reinforced. A section of a textile material, which essentially forms the seat surface 64 and on which a seat cushion (not shown) is arranged, is fastened between the seat longitudinal beams 56 by means of a plurality of screws 62 .

Am sein em vorderen Ende weist jeder der Sitzlängsträger 56 einen Ansatz mit einer Befestigungslasche 66 auf, die eine Bohrung enthält, welche zur Aufnahme einer Schraube vorgesehen ist, mittels welcher das vordere Ende des Sitzlängsträgers 56 in einer von mehreren in Fig. 1 sichtbaren Bohrungen 68 am vorderen Ende des Längsschenkels 12.3 des Seitenträgers des Rollstuhls 10 befestigt ist.At its front end, each of the seat side members 56 has an attachment with a fastening tab 66 , which contains a bore which is provided for receiving a screw, by means of which the front end of the seat side member 56 in one of several bores 68 visible in FIG. 1 is attached to the front end of the longitudinal leg 12.3 of the side member of the wheelchair 10 .

Wie am besten aus Fig. 13 ersichtlich, ist an beiden Sitzlängsträgem 56 im hinteren Bereich der eigentlichen Sitzfläche 64 je ein weiterer, nach unten gerichteter Ansatz bzw. eine weitere Befestigungslasche 70 vorgesehen. Diese Befestigungslaschen 70 dienen zur Anlenkung von je einer Sitzstrebe 72. Die beiden Sitzstreben 72 bilden ein Sitzstrebenpaar und sind durch eine sie verbindende, nicht dargestellte Querstangenanordnung parallelisiert. Jede Sitzstrebe 72 weist eine Vielzahl von Bohrungen 76 auf, die zur Aufnahme einer nicht dargestellten Schraube vorgesehen ist, mittels welcher die Sitzstrebe 72 am hinteren Ende des zugehörigen Längsschenkels 12.3 des Seitenträgers befestigt ist. Durch die jeweilige Wahl der Bohrung 76 für die genannte Schraube wird die wirksame Länge der Sitzstreben 72 und damit der Neigungswinkel der Sitzfläche 64 bestimmt, wobei die maximale Neigung der Sitzfläche 64 etwas geringer ist als die Neigung der Längsschenkel 12.3 der SeitenträgerAs best seen from FIG. 13, according to a further two Sitzlängsträgem 56 in the rear portion of the actual seat surface 64 is provided is directed downward approach or another fastening tab 70. These fastening tabs 70 are used to link each of a seat stay 72 . The two seat stays 72 form a pair of seat stays and are parallelized by a connecting rod arrangement, not shown, connecting them. Each seat strut 72 has a plurality of bores 76 , which is provided for receiving a screw, not shown, by means of which the seat strut 72 is fastened to the rear end of the associated longitudinal leg 12.3 of the side carrier. The effective length of the seat struts 72 and thus the angle of inclination of the seat surface 64 is determined by the respective selection of the bore 76 for the screw mentioned, the maximum inclination of the seat surface 64 being somewhat less than the inclination of the longitudinal legs 12.3 of the side members

Der Rücken 54 weist zwei seitliche Rückenstützen 80 auf, die mittels Winkelplatten 81 an den Sitzlängsträgern 56 befestigt sind, wobei der Winkel zwischen Rücken 54 und Sitzfläche 64 verstellbar ist. Die beiden Rückenstützen 80 sind durch eine nach hinten gewölbte Querstange 82 miteinander verbunden. Gemäss Fig. 11 erstrecken sich zwischen den Rückenstützen in mehrerer Höhen Bänderpaare 84, deren Länge einstellbar ist, und die teilweise mit Klettband 85 versehen sind.The back 54 has two lateral back supports 80 which are fixed to the seat side members 56 by means of angle plates 81, the angle between the back 54 and the seat surface is adjustable 64th The two back supports 80 are connected to one another by a crossbar 82 which is curved to the rear. 11 extend between the back supports at several heights, pairs of bands 84, the length of which is adjustable, and which are partially provided with Velcro 85 .

Der Rücken 54 weist im weiteren ein Rückenkissen 86 mit einem hinteren Kissenteil 86.1, einem vorderen Kissenteil 86.2 und einem am unteren Ende des vorderen Kissenteils 86.2 befestigten Rückenkissenlappen 86.3 auf, der im montierten Zustand zwischen der Sitzfläche 64 und dem Sitzkissen liegt. Wie die Bänderpaare 84 ist auch das Rückenkissen 86 entsprechend mit Klettband 87 versehen.The back 54 also has a back cushion 86 with a rear cushion part 86.1, a front cushion part 86.2 and a back cushion flap 86.3 fastened to the lower end of the front cushion part 86.2 , which in the assembled state lies between the seat surface 64 and the seat cushion. Like the pairs of bands 84 , the back cushion 86 is also provided with Velcro 87 .

Zum Schieben des Rollstuhls 10 dient entweder die Querstange 82 gemäss Fig. 11 oder Handgriffe 88 gemäss Fig. 12A oder höhenverstellbare Handgriffe 90 gemäss Fig. 12B. Either the crossbar 82 according to FIG. 11 or handles 88 according to FIG. 12A or height-adjustable handles 90 according to FIG. 12B are used to push the wheelchair 10 .

Wiederum mit Bezug auf Fig. 13 wird nun beschrieben, welche konstruktiven Massnahmen beim Sitzmodul 50 getroffen sind, um ein Abklappen des Rükkens 54 auf den Sitz 52 zu ermöglichen. Eine Fixierplatte 92 ist mit ihrem vorderen Ende bei 94 schwenkbar am Sitzlängsträger 56 befestigt, wobei mehrere Bohrungen die Montage in verschiedenen Stellungen erlauben, welche die relative Neigung des Rückens 54 zur Sitzfläche 64 bestimmen. Die Fixierplatte 92 weist ferner einen schlitzförmigen Durchbruch 96 auf, in welche ein an der Rückenstütze 80 befestigter Zapfen 97 hineinragt. Der Durchbruch 96 ist an seinem hinteren Ende nach oben erweitert und bildet eine Rastöffnung 96.1 für den Zapfen 97, wenn der Rücken 54 hochgeklappt ist. Um den Rücken 54 abzuklappen, wird an einer die hinteren Enden der Fixierplatte 92 verbindenden Kordel 98 ein Aufwärtszug ausgeübt. Dadurch kommt der Zapfen 97 von der Rastöffnung 96.1 frei und der Rücken 54 kann nach vorne geneigt werden, während sich der Zapfen 97 im Durchbruch 96 verschiebt. Die den Rücken 54 mit dem Sitzlängsträger 56 verbindende Schraube 99 ist nicht fest angezogen sondern dient als Schwenkachse bei der Klappbewegung des Rückens 54.Again, with reference to FIG. 13 , it will now be described which constructional measures have been taken for the seat module 50 in order to enable the back 54 to be folded down onto the seat 52 . A fixing plate 92 is pivotally attached at its front end at 94 to the seat longitudinal member 56 , with a plurality of bores allowing mounting in different positions, which determine the relative inclination of the back 54 to the seat surface 64 . The fixing plate 92 also has a slot-shaped opening 96 , into which a pin 97 fastened to the back support 80 projects. The opening 96 is widened upwards at its rear end and forms a latching opening 96.1 for the pin 97 when the back 54 is folded up. In order to fold down the back 54 , an upward pull is exerted on a cord 98 connecting the rear ends of the fixing plate 92 . As a result, the pin 97 is clear of the latching opening 96.1 and the back 54 can be tilted forward, while the pin 97 moves in the opening 96 . The screw 99 connecting the back 54 to the seat longitudinal member 56 is not tightened but serves as a pivot axis during the folding movement of the back 54 .

Die Fixierplatte 92 dient auch als Montageplatte für eine angeschraubte Kleiderschutzplatte 100 gemäss Fig. 13 oder einen aufsteckbaren Radspritzschutz 102, der in Fig. 14 dargestellt ist. Der Radspritzschutz 102 weist einen zum Rad gebogenen Teil 102.1 und einen vertikalen Teil 102.2 auf. Am letzteren ist eine Aufsteckbride 104 festgeschraubt, wobei am vertikalen Teil für die nicht dargestellten Schrauben keine Bohrungen sondern Schlitze 102.3 vorhanden sind. Dadurch kann die Aufsteckbride 104 in verschiedenen Stellungen festgeschraubt werden, wodurch der Radspritzschutz 102 relativ zur Fixierplatte 92 verschiedene Lagen einnehmen kann.The fixing plate 92 also serves as a mounting plate for a screwed-on clothes protection plate 100 according to FIG. 13 or an attachable wheel splash guard 102, which is shown in FIG. 14 . The wheel splash guard 102 has a part 102.1 bent towards the wheel and a vertical part 102.2 . A plug-on bracket 104 is screwed tightly onto the latter, wherein there are no bores but slots 102.3 on the vertical part for the screws (not shown). As a result, the clip-on bracket 104 can be screwed tight in different positions, as a result of which the wheel splash guard 102 can assume different positions relative to the fixing plate 92 .

Der Rollstuhl 10 kann bei Bedarf mit einer Transitrolleneinrichtung 106 nach Fig. 15 und/oder einer Antikippeinrichtung 108 nach Fig. 16 ausgerüstet werden.If necessary, the wheelchair 10 can be equipped with a transit roller device 106 according to FIG. 15 and / or an anti-tip device 108 according to FIG. 16 .

Fig. 15 zeigt eine Transitrolleneinrichtung und Fig. 16 eine Antikippeinrichtung, die optional am Rollstuhl 10 angeordnet werden können. FIG. 15 shows a transit roller device and FIG. 16 shows an anti-tipping device which can optionally be arranged on the wheelchair 10 .
