Description

Die Erfindung bezieht sich auf einen Falt-Rollstuhl mit einem von Rädern getragenen Untergestell, auf bzw. an dem eine Sitzfläche, eine Rückenlehne und seitliche Armlehnen angeordnet sind.The invention relates to a folding wheelchair with a base supported by wheels, on or on which a seat, a backrest and side armrests are arranged.

Derartige Rollstühle sind in verschiedenen Ausführungen bekannt geworden. Nachteilig an den üblicherweise eingesetzten Rollstühlen ist die fehlende Verstellmöglichkeit bezüglich der Breite der Sitzfläche, so dass sie in verschiedenen Breiten vorgehalten werden müssen.Such wheelchairs have become known in various designs. A disadvantage of the wheelchairs commonly used is the lack of adjustment with respect to the width of the seat so that they must be kept in different widths.

Zwar sind schon verschiedene Vorschläge für Breitenverstellungen gemacht worden, diese sind aber entweder aufwändig oder in der Praxis nicht ausreichend sicher.Although various proposals have been made for width adjustments, but these are either expensive or not sufficiently safe in practice.

Es ist bekannt, bei Falt-Rollstühlen die Kreuzstreben aus Teleskoprohren zu bilden, die durch Rasten, teilweise mit Sicherungsstiften, in der Länge der Streben und dadurch in der Sitzbreite verstellbar sind, siehe z.B. US 4,082,348 ; US 2,669,289 ; US 4,989,890 und DE 203 10 215 .It is known to form the cross struts of telescopic tubes in folding-wheelchairs, which are adjustable by means of detents, sometimes with locking pins, in the length of the struts and thereby in the seat width, see, for example U.S. 4,082,348 ; US 2,669,289 ; US 4,989,890 and DE 203 10 215 ,

DE GM 89 13 468 schlägt vor, bei einem Falt-Rollstuhl die Kreuzstrebe als Doppel-V-förmige Faltrohrschere mit verstellbaren Gelenkpunkten auszubilden.DE GM 89 13 468 proposes to form the cross strut in a folding wheelchair as a double V-shaped folding tube scissors with adjustable hinge points.

DE GM 93 14 406 beschreibt einen Bausatz, aus dem unter Verwendung einzelner, in unterschiedlicher Baugröße vorgehaltener Teile, ein in den Abmessungen an den Benutzer angepasster Rollstuhl montiert wird. Hierbei bleibt aber die Notwendigkeit bestehen, individuell an die Größe angepasste Teile vorrätig zu halten.DE GM 93 14 406 describes a kit from which, using individual, held in different sizes reproached parts, a dimensioned in the dimensions of the user wheelchair is mounted. Here, however, there remains the need to keep individually adapted to the size of stock parts.

Gemäß DE 37 08 302 wird eine gewisse Anpassung eines Rollstuhles durch eine in allen drei Raumrichtungen verstellbare Sitzfläche erreicht, eine wirkliche Breitenanpassung des Rollstuhles als Ganzes besteht nicht.According to DE 37 08 302 If a certain adaptation of a wheelchair is achieved by means of a seat which can be adjusted in all three spatial directions, a true width adjustment of the wheelchair as a whole does not exist.

Auf einem ähnlichen Ansatz beruht DE GM 90 12 190 , bei dem zur Anpassung der Sitzbreite eine Verstellung der Armlehnen vorgeschlagen wird.Based on a similar approach DE GM 90 12 190 , in which an adjustment of the armrests is proposed for adjusting the seat width.

Aufgabe der Erfindung ist es deshalb, den nach der eingangs genannten Art aufgebauten Falt-Rollstuhl durch einfach aufgebaute und leicht zu bedienende Mittel mit einer Möglichkeit zur Anpassung der Breite auszustatten, um somit das Vorhalten von Rollstühlen verschiedener Breiten bzw. Bauteilen verschiedener Breiten entbehrlich zu machen. Weiterhin soll trotz Anpassung eine hohe Stabilität und Sicherheit gewährleistet sein.The object of the invention is therefore to provide the constructed according to the type mentioned folding wheelchair by simply constructed and easy-to-use means with a possibility for adjusting the width, thus making the provision of wheelchairs different widths or components of different widths unnecessary , Furthermore, a high stability and security should be ensured despite adjustment.

Diese Aufgabe wird erfindungsgemäss gelöst, indem bei einem Falt-Rollstuhl mit einem von Rädern getragenen Untergestell, auf bzw. an dem eine Sitzfläche, eine Rückenlehne und seitliche Armlehnen angeordnet sind, das Untergestell durch eine Kreuzstrebe gebildet wird, deren Streben jeweils aus einem inneren und zwei äußeren Rohren bestehen, die über ein Gewinde miteinander längenveränderlich verbunden sind.This object is achieved according to the invention by a folding wheelchair with a base supported by wheels, on or on which a seat, a backrest and side armrests are arranged, the base is formed by a cross strut, the struts each of an inner and consist of two outer tubes, which are connected by a thread variable length.

Diese Konstruktion bietet den Vorteil, dass trotz der einfachen Verstellung eine große Stabilität und Sicherheit erreicht wird, da bei einem Gewinde ein ungewolltes Verschieben oder gar Herausrutschen weitgehend ausgeschlossen ist. Auch ermöglicht die Konstruktion eine im wesentlichen stufenlose Verstellung.This construction offers the advantage that, despite the simple adjustment, a high degree of stability and safety is achieved, since with a thread an unintentional displacement or even slipping out is largely precluded. Also allows the construction of a substantially continuous adjustment.

In einer bevorzugten Ausführungsform ist die Position der inneren und äußeren Rohre zueinander durch ein Kontermutter fixierbar.In a preferred embodiment, the position of the inner and outer tubes is fixable to each other by a lock nut.

Es ist weiterhin vorteilhaft, die Stellung der Gewinde durch Markierungen kenntlich zu machen, so dass eine gleichmäßige Einstellung der Länge beider Kreuzstreben gewährleistet ist. Hierzu kann beispielsweise eine Längsmarkierung in dem Gewinde vorgesehen sein. Ebenso ist es möglich, in bestimmten Abständen umlaufende Markierungen vorzusehen. Diese können beispielsweise aus Ziffern, Buchstaben oder Farben bestehen.It is also advantageous to make the position of the threads by markings, so that a uniform adjustment of the length of both cross struts is guaranteed. For this purpose, for example, a longitudinal mark can be provided in the thread. It is also possible to provide circumferential markings at certain intervals. These can, for example, consist of numbers, letters or colors.

Dabei ist es auch grundsätzlich möglich, die äußeren und inneren Rohre mit rechts/links Gewinden zu versehen, so dass eine Drehung des Innenrohres die aufgeschraubten (äußeren) jeweils nach außen weitet oder einander annähert. Dazu ist lediglich die achsenförmige Gelenkverbindung herauszuziehen, um die Innenrohre drehen zu können. Diese bildet gleichzeitig eine Sicherung gegen unbeabsichtigtes Verstellen.It is also basically possible to provide the outer and inner tubes with right / left threads, so that a rotation of the inner tube expands the screwed (outer) in each case to the outside or approaches each other. For this purpose, only the axis-shaped articulated connection is pulled out to rotate the inner tubes can. This also forms a safeguard against unintentional adjustment.

Selbstverständlich kann die erfindungsgemäße Breitenverstellung noch durch an sich bekannte Maßnahmen um eine Sitzhöhen- und/oder Sitztiefenverstellung ergänzt werden.Of course, the width adjustment according to the invention can be supplemented by measures known per se by a Sitzhöhen- and / or seat depth adjustment.

Anhand der Zeichnungen wird nachfolgend ein Ausführungsbeispiel gemäss der Erfindung näher erläutert, ohne dass die Erfindung auf die spezielle gezeigte Gestaltung beschränkt wäre.An embodiment according to the invention will be explained in more detail below with reference to the drawings, without the invention being restricted to the specific design shown.

Es zeigen:

  • Figur 1 eine erfindungsgemäß ausgebildete Kreuzstrebe.
  • Figur 2 einen Rollstuhl in Seitenansicht
  • Figur 3 einen solchen von hinten und
  • Figur 4 Sitz- bzw. Rückenlehnengurte
Show it:
  • Figure 1 is an inventively designed cross strut.
  • Figure 2 shows a wheelchair in side view
  • Figure 3 such from the back and
  • Figure 4 seat or backrest straps

Die Kreuzstrebe 10 in Fig. 1 wird von zwei Streben gebildet, die jeweils aus einem inneren Rohr 11 und zwei äußeren Rohren 12 bestehen. Die inneren Rohre 11 sind in an sich bekannter Weise über eine Gelenkverbindung zu der Kreuzstrebe 10 vereinigt. Die inneren Rohre 11 sind über Gewinde 13 mit den äußeren Rohren längenveränderlich verbunden. Im gezeigten Beispiel tragen die inneren Rohre ein Außengewinde und die äußeren Rohre das dazu passende Innengewinde. Die gewählte Längeneinstellung ist durch Kontermuttern 14 zusätzlich sicherbar. An den dem Gewinde 14 gegenüberliegenden Enden sind die äußeren Rohre 12 an den Seitenrahmen 8 angelenkt.The cross brace 10 in Fig. 1 is formed by two struts, each consisting of an inner tube 11 and two outer tubes 12. The inner tubes 11 are in a conventional manner via a hinge connection to the crossbar 10 united. The inner tubes 11 are connected via threads 13 with the outer tubes variable in length. In the example shown, the inner tubes carry an external thread and the outer tubes have the matching internal thread. The selected length adjustment is additionally secured by lock nuts 14. At the opposite ends of the thread 14, the outer tubes 12 are hinged to the side frame 8.

Das Innenrohr 11 weist dabei vorteilhaft an seinen Enden gegensinnige Rechts/Linksgewinde auf, so dass zum Verstellen lediglich das Innenrohr 11 gedreht zu werden braucht, ohne die Außenrohre 12 vom Rahmen des Rollstuhls lösen zu müssen.The inner tube 11 has advantageously at its ends opposing right / left-hand thread, so that for adjusting only the inner tube 11 needs to be rotated without having to solve the outer tubes 12 from the frame of the wheelchair.

Fig. 2 zeit einen Rollstuhl 1 herkömmlicher Art, in den zwei Kreuzstreben 10 gemäß Fig. 1 eingebaut sind. Dieser umfasst kleine Vorderräder 5 sowie größere Hinterräder 6, die an einem Untergestell 9 befestigt sind. Auf diesen ruht ein Seitenrahmen 8 mit den Armlehnen 4. Zwischen zwei dieser Teile 8, 9 befindet sich ein Holm 2 zur Befestigung einer Sitzfläche. Fig. 2 time a wheelchair 1 conventional type, are installed in the two cross struts 10 of FIG. This includes small front wheels 5 and larger rear wheels 6, which are fixed to a base frame 9. On these rests a side frame 8 with the armrests 4. Between two of these parts 8, 9 is a spar 2 for attachment of a seat.

Die Rückenlehne 3 weist zwei Griffe 7 mit entsprechenden Streben 15 auf, zwischen die Gurte gespannt sind, ebenso zwischen den Holmen 2 zur Bildung der Sitzfläche (Fig 3+4).The backrest 3 has two handles 7 with corresponding struts 15, are stretched between the straps, as well as between the bars 2 to form the seat (Fig 3 + 4).

Fig 3 veranschaulicht die Breitenverstellung des Rollstuhls. Dabei sind die Kreuzstreben 10 durch drehen der Innenrohre 12 elongiert, wodurch die Kreuzstrebe 10 gestreckt wird und die Außenrohre 1 und ebenso der gesamte Seitenrahmen nach außen versetzt ist, wie mit den Positionen 7' für den Griff und 6' für das Hinterrad angedeutet. Fig. 3 illustrates the width adjustment of the wheelchair. In this case, the cross braces 10 are elongated by rotating the inner tubes 12, whereby the cross brace 10 is stretched and the outer tubes 1 and also the entire side frame is offset outwardly, as indicated by the positions 7 'for the handle and 6' for the rear wheel.

Um dies zu ermöglichen, ohne eine breitere Sitzfläche und eine breitere Lehne verwenden zu müssen, bestehen Sitzfläche und Lehne aus Einzelgurten, die längenverstellbar sind.
Der Vorteil der Verwendung separater Gurtzüge liegt auch darin, dass diese dem individuellen Körperbau angepasst werden können, d.h. die Einzelgurte können unterschiedlich lang sein.To make this possible, without having to use a wider seat and a wider backrest, seat and back consist of individual straps, which are adjustable in length.
The advantage of using separate belts is also that they can be adapted to the individual physique, ie the individual straps can be different lengths.

Fig. 4 zeigt die Konstruktion einer solchen erfindungsgemäßen Rückenlehne oder Sitzfläche. Fig. 4 shows the construction of such a backrest or seat according to the invention.

Diese bestehen aus je zwei aneinander stoßenden seitlichen Streifen 16, 17, die zusammengefügt die entsprechenden Seitenteile des Rollstuhls umfassen d.h. z.B. entweder zusammengenäht eine Hülse bilden, oder die entsprechenden Rohre in Klettverschluß umfassen. Zwischen den seitlichen Gewebestreifen 16, 17 sind Gurte 18 angeordnet, die eine kürzere Lasche 19 aufweisen, die endseitig eine Öse 20 tragen.These consist of two abutting side strips 16, 17, which together comprise the corresponding side parts of the wheelchair, i. e.g. either sewed together form a sleeve, or include the corresponding tubes in Velcro. Between the side fabric strips 16, 17 straps 18 are arranged, which have a shorter tab 19, the end wear an eyelet 20.

Die längeren Gurtenabschnitte 21 sind von oben durch die Ösen 20 geschoben und an der Unterseite in Klettverschluß gehalten. Damit sind die Lehne und der Sitz auf sehr einfache Weise verstellbar.The longer belt sections 21 are pushed from above through the eyelets 20 and held at the bottom in Velcro. Thus, the backrest and the seat are adjustable in a very simple manner.
