Definitions
- the invention relates to a wheelchair frame consisting of two opposite side frames, which are connected to each other via at least one transverse strut, a seat and a back frame, and each having a substantially horizontal, the seat receiving, upper strut and a lower strut connected thereto.
- Such a wheelchair frame is for example from the DE 20 2004 005 653 U1 known.
- the two struts of the frame are connected at their front end by being welded to a vertical tube. At their rear end, they are screwed together via a vertical strut, which can simultaneously accommodate a bearing for a drive wheel.
- the back frame is bolted to the wheel bearing strut.
- the known compounds are time consuming and expensive to produce.
- the invention is therefore based on the object to simplify the structure of the side frame and to allow a quick installation.
- a generic wheelchair frame is characterized in that the two struts are connected to each other at their end facing the back frame via a one-piece pipe bend, and that the diameter of the pipe bend is different in size at its two ends. It may be the inner diameter and / or the outer diameter at the two ends of different sizes.
- the upper strut can be connected to the tubular frame by a sleeve or a screw connection.
- the different diameter of the ends of the pipe bend allow to use conventional pipes for the lower strut and the back frame, which favors the modular structure of a wheelchair frame and reduces the manufacturing costs, since the storage can be kept small.
- connectors are much faster to produce than screw or welded connections.
- the lower ends of which are insertable into the upper ends of the pipe bends, are preferably arranged at the upper end of push handles.
- the wheelchair consists of the frame, which has two opposite side frames 1, 2.
- Each side frame 1, 2 consists of a horizontally extending upper strut 3 and a parallel thereto lower strut 4.
- the struts 3, 4 are connected to each other at its front end via a strut 8 and at its rear end via the integral pipe bend 7.
- the footrest bracket 9 are attached to the footrest 10.
- the side frames 1, 2 are connected to each other via the seat 5 and the cross strut 11.
- the one-piece pipe bend 7 is butted.
- the inner diameter D 1 of the upper end 7 ' is larger than the inner diameter D 2 at the lower end.
- the lower end 7 "of the pipe bend 7 is fixedly connected to the strut 4 by a hinge element 16 around which the cross strut 11 moves.
- the hinge element 16 is inserted into the end 7" of the pipe bend 7.
- the tubes 6a of the back frame 6 are respectively inserted, which have the push handles 12 at the opposite ends.
- a fabric 15 is provided, which forms the backrest for the wheelchair.
- a steerable front wheel 14 is still attached to the lower strut 4 and between the upper strut 3 and the lower strut 4 is in the rear area depending on a drive wheel 15 mounted vertically adjustable.

Abstract
Description
Die Erfindung betrifft einen Rollstuhlrahmen, bestehend aus zwei sich gegenüberliegenden Seitenrahmen, die über mindestens eine Querstrebe, einen Sitz und einen Rückenrahmen miteinander verbunden sind, und die jeweils eine im Wesentlichen horizontale, den Sitz aufnehmende, obere Strebe und eine damit verbundene untere Strebe aufweisen.The invention relates to a wheelchair frame consisting of two opposite side frames, which are connected to each other via at least one transverse strut, a seat and a back frame, and each having a substantially horizontal, the seat receiving, upper strut and a lower strut connected thereto.

Die bekannten Verbindungen sind zeit- und kostenaufwendig herzustellen. Der Erfindung liegt deshalb die Aufgabe zugrunde, den Aufbau der Seitenrahmen zu vereinfachen und eine schnelle Montage zu gestatten.The known compounds are time consuming and expensive to produce. The invention is therefore based on the object to simplify the structure of the side frame and to allow a quick installation.
Zur Lösung der Aufgabe zeichnet sich ein gattungsgemäßer Rollstuhlrahmen dadurch aus, dass die beiden Streben an ihren dem Rückenrahmen zugewandten Ende über einen einteiligen Rohrbogen miteinander verbunden sind, und dass der Durchmesser des Rohrbogens an seinen beiden Enden unterschiedlich groß ist. Es kann der Innendurchmesser und/oder der Außendurchmesser an den beiden Enden unterschiedlich groß sein.To solve the problem, a generic wheelchair frame is characterized in that the two struts are connected to each other at their end facing the back frame via a one-piece pipe bend, and that the diameter of the pipe bend is different in size at its two ends. It may be the inner diameter and / or the outer diameter at the two ends of different sizes.
Durch diese Ausgestaltung ist es möglich, den Rohrbogen als separates Bauteil herzustellen und die untere Strebe in das eine Ende des Rohrbogens einzustecken und in das andere Ende jeweils ein unteres Ende des Rückenrahmens einzustecken oder aufzustecken.By this configuration, it is possible to produce the pipe bend as a separate component and to insert the lower strut in one end of the pipe bend and plug in the other end in each case a lower end of the back frame or aufzustecken.
Die obere Strebe kann mit dem Rohrrahmen durch eine Muffe oder eine Verschraubung verbunden werden. Die unterschiedlich großen Durchmesser der Enden des Rohrbogens gestatten es, herkömmliche Rohre für die untere Strebe und den Rückenrahmen zu verwenden, was den modularen Aufbau eines Rollstuhlrahmens begünstigt und die Herstellkosten reduziert, da die Lagerhaltung klein gehalten werden kann. Außerdem sind Steckverbindungen wesentlich schneller herstellbar als Schraub- oder Schweißverbindungen.The upper strut can be connected to the tubular frame by a sleeve or a screw connection. The different diameter of the ends of the pipe bend allow to use conventional pipes for the lower strut and the back frame, which favors the modular structure of a wheelchair frame and reduces the manufacturing costs, since the storage can be kept small. In addition, connectors are much faster to produce than screw or welded connections.
An dem Rückenteil, das einen Rohrrahmen aufweist, dessen untere Enden in die oberen Enden der Rohrbögen einsteckbar sind, sind vorzugsweise an dessen oberen Ende Schiebegriffe angeordnet.At the back part, which has a tubular frame, the lower ends of which are insertable into the upper ends of the pipe bends, are preferably arranged at the upper end of push handles.
