Zur Problemlösung zeichnet sich ein gattungsgemäßer Faltrollstuhl durch folgende Merkmale aus:
- a) die Sitzrohre (10, 10') bestehen aus einem Außenrohr (11, 11') und einem Innenrohr (12, 12'),
- b) das Außenrohr (11, 11') weist einen sich in Längsrichtung (L) erstreckenden Schlitz (111) auf, der zumindest in ein Außenrohrende (117) mündet,
- c) das Innenrohr (12, 12') weist einen sich in Längsrichtung (L) erstreckenden Schlitz (121) auf, der zumindest in ein Innenrohrende (127) mündet,
- d) jede Bespannungsstange (20, 20') ist in einem Außenrohr (11, 11') aufgenommen und mündet in das zugehörige Innenrohr (12, 12'),
- e) das Gewebe (3) ist durch die Schlitze (111, 121) vom Innenrohr (12, 12') und Außenrohr (11, 11') nach außen geführt,
- f) das Innenrohr (12, 12'), das Gewebe (3) und die Bespannungsstange (20, 20') sind miteinander verbunden.
- a) the seat tubes (10, 10 ') consist of an outer tube (11, 11') and an inner tube (12, 12 '),
- b) the outer tube (11, 11 ') has a slot (111) extending in the longitudinal direction (L), which opens at least into an outer tube end (117),
- c) the inner tube (12, 12 ') has a slot (121) extending in the longitudinal direction (L), which opens at least into an inner tube end (127),
- d) each stringing rod (20, 20 ') is received in an outer tube (11, 11') and opens into the associated inner tube (12, 12 '),
- e) the fabric (3) is guided through the slots (111, 121) from the inner tube (12, 12 ') and outer tube (11, 11') to the outside,
- f) the inner tube (12, 12 '), the fabric (3) and the stringing bar (20, 20') are interconnected.
Durch diese Ausgestaltung wird das Gewebe, das mit dem Innenrohr verbunden ist, im Außenrohr verschoben, wobei die Führung über die Bespannungsstange und die Schlitze in den Außenrohren erfolgt. Die Sitzfläche bleibt bei einer Einstellung der Sitztiefe unverändert, die Sitzfläche selbst wird nur weiter nach vorn oder zurück verlagert. Das Gewebe bleibt bei einer Veränderung der Sitztiefe immer gespannt. Faltenbildung ist ausgeschlossen, sodass Druckstellen am Körper des Benutzers sicher vermieden werden.By this configuration, the tissue which is connected to the inner tube, moved in the outer tube, wherein the guide via the stringing rod and the slots in the outer tubes takes place. The seat remains unchanged when adjusting the seat depth, the seat itself is only moved further forward or backward. The fabric always stays taut when the seat depth changes. Wrinkling is excluded, so that pressure sores on the user's body are safely avoided.
Vorzugsweise ist zwischen jedem Innenrohr und jeder Bespannungsstange eine mit einem in Längsrichtung durchgängigen Schlitz versehene Hülse angeordnet, die insbesondere vorzugsweise mit einer Gewindebohrung versehen sein kann, in die eine das Gewebe an der Bespannungsstange fixierende Schraube eindrehbar ist. Über diese Hülse wird das Gewebe im Außenrohr verschoben, wobei die Hülse mit dem Innenrohr verbunden ist.Preferably, a sleeve provided with a slit extending in the longitudinal direction is provided between each inner tube and each stringing rod, which sleeve may in particular preferably be provided with a threaded bore into which a screw fixing the fabric to the stringing rod can be screwed. About this sleeve, the tissue is moved in the outer tube, wherein the sleeve is connected to the inner tube.
Vorzugsweise sind die Hülse und die Bespannungsstange über die Schraube miteinander verbunden. Die Schraube kann durch das Gewebe und eine Ausnehmung oder eine Durchgangsbohrung in die Bespannungsstange eingreifen.Preferably, the sleeve and the stringing rod are connected to each other via the screw. The screw can engage through the fabric and a recess or through-hole in the stringing bar.
Anstatt eine Hülse vorzusehen, kann das Innenrohr aber auch unmittelbar mit der Bespannungsstange verbunden werden.Instead of providing a sleeve, the inner tube can also be connected directly to the stringing rod.
Um den Aufbau des Innenrohres zu vereinfachen und eine optisch hochwertige Anmutung zu schaffen, kann das Innenrohr an seinem vom Gewebe abgewandten Ende mit einem Stopfen verschlossen werden.In order to simplify the structure of the inner tube and to create a visually high-quality appearance, the inner tube can be closed at its end remote from the tissue with a stopper.
Um die Teleskopierbarkeit der oberen Sitzrohre zu vereinfachen, sind die Außenrohre mit einer Mehrzahl in Längsrichtung parallel zueinander beabstandeter Löcher versehen, die jeweils mit einem im Innenrohr angeordneten Zapfen zur Einstellung der Sitztiefe des Sitzes zusammenwirken. Die Zapfen sind vorzugsweise gegen die Kraft einer Feder verschiebbar.In order to simplify the telescoping of the upper seat tubes, the outer tubes are provided with a plurality of longitudinally parallel spaced holes, each cooperating with a pin arranged in the inner tube for adjusting the seat depth of the seat. The pins are preferably displaceable against the force of a spring.
Das Innenrohr kann auch klemmend, beziehungsweise kraft- und/oder reibschlüssig mit dem Außenrohr verbunden werden, so dass eine stufenlose Teleskopierbarkeit der oberen Sitzrohre möglich ist.The inner tube can also be connected by clamping, or force and / or frictional engagement with the outer tube, so that a stepless telescoping of the upper seat tubes is possible.
