Abstract

Wheelchair has a rotatable handgrip used for transferring drive force provided by the arm and the hand of the user to the driven wheel. Handgrip is provided by a radial holder (1) supported by a bearing (2) from the wheel hub (3) and having a clamp frame (4) with a friction pad (5) engaging the grip ring (8) attached to the wheel. The handgrip is pivoted transverse to the travel direction for disengaging it from the wheel.

Description

Allgemein gebräuchliche Rollstühle für Selbstfahrer sind ausgestattet mit Greifreifen, welche zum Antrieb mit den Händen erfasst und bewegt werden. Um den zum Fahren erforderlichen Schub zu erzeugen, muss zwischen Hand und Reifen ein Reibschluss aufgebaut werden. Hierzu ist ein Druck auf den Reifen nötig, welcher einen nicht unbeträchtlichen Teil der vorhandenen Armkräfte beansprucht. Behinderte Personen haben oftmals keine Kraft, diesen Druck auszuüben. Auch anormale Handaus­ bildungen können den Kontakt mit dem Greifreifen erschweren oder un­ möglich machen. Eine unangenehme Folge dieser Antriebsart ist auch das Unvermeidliche Entstehen von Hautverschiebungen und -verhärtungen. Der nachfolgend beschriebene Rollstuhl mit Antriebshilfe kann diese Schwierigkeiten überbrücken. Es handelt sich darum, den Kontakt zerischen Hand und Reifen mit einem Handgriff herzustellen; welcher infolge von Hebelwirkung auch mit sehr geringer Armkraft einen zuver­ lässigen Kraftschluss bewirkt. Auch kann die Handauflage des Hand­ griffes individuell einer Behinderung entsprechend gestaltet werden. Die Antriebskraft wird dabei entweder direkt auf den Schlauchmantel oder auf den Greifreifen übertragen. Durch entsprechende Material­ paarung und Oberflächenrauhigkeit ist ein zuverlässiger Kraftschluss gegeben, z. B. Kunststoff-Gummi oder dergleichen. Für die Freilauf­ phase des Antriebsvorganges wird der Kontakt mit dem Reifen durch seitliches Abschwenken des Handgriffs gelöst, Beispiel hier: Greifreifen. Der Handgriff besteht aus einem radialen Halter (1), welcher über ein Lager (2) achsmittig drehbar mit der Radnabe (3) verbunden ist, einem Klemmbügel (4) mit Reibbelag (5) und Handauflage, z. B. Kugel (6). Halter und Klemmbügel sind gelenkig miteinander verbunden (7). Zum An­ treiben (10) wird der Klemmbügel (4) auf den Greifreifen (8) geschwenkt (11) und leicht angedrückt, für den Freilauf durch Anschlag (9) begrenzt abgeschwenkt. Der Greifreifen ist mit einem handelsüblichem rutsch­ festem Überzug (12) versehen.Commonly used wheelchairs for self-drivers are equipped with push rims, which are gripped and moved by hand to drive them. In order to generate the thrust required for driving, a frictional connection must be established between the hand and the tire. This requires pressure on the tire, which takes up a not inconsiderable part of the existing arm forces. Disabled people often have no strength to apply this pressure. Abnormal hand training can also make contact with the push rim difficult or impossible. An unpleasant consequence of this type of drive is the inevitable occurrence of skin shifts and hardening. The wheelchair with drive aid described below can bridge these difficulties. It is a matter of making contact between the hand and the tire with one hand; which results in a reliable adhesion due to leverage even with very little arm strength. The palm rest of the handgrip can also be designed individually to suit a disability. The driving force is transferred either directly to the tubular casing or to the push rim. Appropriate material pairing and surface roughness ensure reliable adhesion, e.g. B. plastic rubber or the like. For the freewheeling phase of the drive process, the contact with the tire is released by swiveling the handle sideways, example here: push rims. The handle consists of a radial holder ( 1 ) which is rotatably connected to the wheel hub ( 3 ) via a bearing ( 2 ), a clamping bracket ( 4 ) with a friction lining ( 5 ) and a hand rest, e.g. B. ball ( 6 ). Bracket and clamp are articulated together ( 7 ). To drive ( 10 ), the clamping bracket ( 4 ) on the hand rim ( 8 ) is pivoted ( 11 ) and slightly pressed, for free-running by the stop ( 9 ) swiveled to a limited extent. The push rim is provided with a commercially available non-slip cover ( 12 ).
