Abstract

A control column of the joy-stick type has its main control-rod (12) suspended in the wall (16) of hermetically-sealed housing (14) by a moulded sphere (18) and is further equipped with a swivelling plate- or disc-shaped pressure element (15), which is positioned diametrally opposite the sphere. Pressure sensors (25) are arranged between the pressure element and the housing. At least one sensor is loaded axiparallely to the control column by the pressure element, and one other, transversely to the axis of the control column, with pressure-springs (22) tensioned between the pressure plate and the housing in the direction of the mechanical sensor-loading-stress.

Description

Die Erfindung betrifft einen Steuerknüppel gemäß dem Oberbegriff des Anspruches 1, wie er als Joystick für Computer-Eingaben (auch als Maus-Ersatz) oder als Stellelement an mobilen oder an stationären Geräten (wie an Behinderten-Selbstfahrstühlen oder zur Bedienung von Handhabungs-Robotern) geläufig ist. Solche Steuerknüppel weisen übli­ cherweise große Auslenkwinkel und somit große Betätigungswege in einander entgegen­ gesetzten oder gar in orthogonalen Richtungen auf, um mit entsprechendem Hub Poten­ tiometerabgriffe zu verschieben oder Schalter zu betätigen.The invention relates to a joystick according to the preamble of claim 1. like it is used as a joystick for computer inputs (also as a mouse replacement) or as an actuator on mobile or stationary devices (such as handicapped self-propelled chairs or for Operation of handling robots) is common. Such sticks have übli large deflection angles and thus large actuation paths towards each other set or even in orthogonal directions to pots with appropriate stroke to move tiometer taps or to operate switches.

Diese vergleichsweise großen Wege, die bei der richtungsabhängigen Steuerungseingabe auftreten, bedingen entsprechend aufwendige Rückführmechanismen, um die Handhabe nach Beendigung ihrer manuellen Auslenkung aus allen Auslenkrichtungen gleicherma­ ßen rasch und zuverlässig wieder in die neutrale Mitten- oder Nullstellung zurückzufüh­ ren. Bei schnellen Reaktions-Erfordernissen seitens des Bediener stellt sich in der Praxis ein solcher wegabhängig reagierender Steuerknüppel aber häufig als handhabungstech­ nisch nachteilig heraus. Vor allem jedoch besteht bei muskel- oder nervengeschädigten Behinderten oft das Problem, daß sie kaum noch bis gar nicht mehr in der Lage sind, mit Unterarm und Handballen reproduzierbar eine gezielte räumliche Bewegung auszuführen - zumal wenn dabei die Hand gewissermaßen auf dem Knauf am bedienungsseitigen Ende eines Steuerknüppels "balanciert" oder sogar erst gezielt an die Handhabe herangeführt und mit dieser dann wieder ausgelenkt werden muß.These comparatively large paths, which are used for directional control input occur, require correspondingly complex return mechanisms to handle after completing their manual deflection from all deflection directions alike quickly and reliably return to the neutral center or zero position In the case of quick reaction requirements on the part of the operator, this arises in practice such a path-dependent control stick but often as a handling tech nisch disadvantageous out. But above all, there is muscle or nerve damage Disabled often the problem that they are hardly or no longer able to help Forearm and ball of the hand reproducibly perform a targeted spatial movement - especially when the hand is on the knob at the operator end of a joystick "balanced" or even introduced to the handle and then it has to be deflected again.

Um diesem Problemkomplex abzuhelfen, ist es Gegenstand der Erfindung gemäß der eigenen prioritätsbegründenden Gebrauchsmuster-Anmeldung 29609458.7 vom 28. Mai 1996, einen praktisch weglos und spielfrei arbeitenden Steuerknüppel zur Verfügung zu stellen, indem die Handhabe als gelenkig aufgehängter ein- oder zweiarmiger Hebel ständig gegen einen druckabhängig reagierenden Sensor anliegt, der seinerseits praktisch weglos arbeitet. Die Dynamik eines solchen Steuerknüppels ist dann nicht mehr von der Geschwindigkeit der Schwenkauslenkung eines beweglichen Steuerknüppels abhängig, sondern von der einfacher beherrschbaren Intensität der seitlichen Druckausübung gegen einen an sich starr gehalterten Steuerknüppel (wobei dessen Handhabungs-Ende auch elastisch biegsam an den eigentlichen druckübertragenden Hebelarm angeschlossen sein kann). Im Interesse von möglichst eindeutig nur bedienungsabhängigen Einwir­ kungen auf den Sensor ist die Handhabe vorzugsweise in einem Wälzkörper-Gelenk (Walze bzw. Kugel) im indifferenten Gleichgewichtszustand aufgehängt, so daß lage­ oder erschütterungsabhängige Sensorbeanspruchungen weitestgehend vermieden sind. Wegen konstruktiver Einzelheiten wird hier ausdrücklich auf jene prioritätsbegründende Anmeldung und auf die darin genannten älteren Anmeldungen zu diesem Komplex Bezug genommen.In order to remedy this complex of problems, it is the subject of the invention according to own priority utility model application 29609458.7 from May 28th 1996, a practically pathless and play-free joystick is available by using the handle as an articulated one- or two-armed lever is constantly against a pressure-sensitive sensor, which in turn is practical  works without a path. The dynamics of such a joystick is then no longer of that Speed of the swivel deflection of a movable control stick depends on but from the more easily manageable intensity of lateral pressure a control stick rigidly held per se (whereby its handling end also be connected elastically and flexibly to the actual pressure-transmitting lever arm can). In the interest of a user-dependent operator who is as clear as possible The handle is preferably in a roller joint (Roller or ball) suspended in the indifferent equilibrium state, so that lay or vibration-dependent sensor stresses are largely avoided. Because of constructive details, we explicitly refer to those reasons for priority Registration and reference to the older applications to this complex mentioned therein taken.

Vorliegender Erfindung liegt nun die ergänzende Aufgabenstellung zugrunde, insbeson­ dere motorisch sehr gestörten Benutzern eines solchen Steuerknüppels die Bedienung noch weiter zu erleichtern.The present invention is based on the additional task, in particular the motorized very disturbed users of such a joystick the operation to make it even easier.

Diese technische Problematik ist durch den Hauptanspruch gelöst, wie nachstehend an­ hand der Zeichnungsbeschreibung und mittels weiterführender Ansprüche sowie der ab­ schließenden Kurzfassung beispielshalber näher erläutert.This technical problem is solved by the main claim, as below hand of the drawing description and by means of further claims as well as from closing short version explained for the sake of example.

Die einzige Figur der Zeichnungsskizze zeigt stark abstrahiert in Seitenansicht, wie die Handhabe 1 eines Steuerknüppels 2 vorstehend erläuterten Aufbaues nun erfindungsge­ mäß nicht mehr aus einer Auflagefläche 3 für die Hand 4 des Bedieners hervorragt, son­ dern gewissermaßen kopfüber so weit oberhalb der jetzt für die Hand 4 freigehaltenen Auflagefläche 3 schwebt, daß die Hand 4 im dargestellten Beispielsfall als geballte Faust mit aufgerichtetem Daumen 5 unter der Halterung 10 für den Steuerknüppel 2 auf die Fläche 3 aufgelegt werden kann. Zur Orientierung beim Ablegen der Faust und zur Ab­ stützung gegen die seitliche Druckausübung auf die Handhabe 1 ragt aus der Auflageflä­ che 3 eine Ausbeulung 12 hervor. Bei hier abgelegter Faust sollte das freie Stirnende 6 der Handhabe 1 angenähert vertikal und vorzugsweise etwas gegen die Vertikale geneigt auf den Handballen zu weisend im Bogen-Innern des zur Faust gekrümmten Zeigefingers 7 enden, während der hochgestreckte Daumen 5 oberhalb des Stirnendes 6 seitlich gegen die stabförmig herabragende Handhabe 1 anliegt. So kann aus der unter dem Steuer­ knüppel 2 stabil gelagerten da gewichtsmäßig entlasteten und in der Umgebung der Aus­ buchtung 12 flächig abgestützten Hand 4 durch Druck mit dem Daumen 5 bzw. durch Zug mit dem Zeigefinger 7 eine reproduzierbare Biegebeanspruchung in einander entge­ gengesetzten Richtungen an der Handhabe 1 hervorgerufen und gemäß den Hebel-Gege­ benheiten der Handhaben-Aufhängung als Druckbeanspruchung auf die kontinuierlich oder schaltend reagierenden Sensoren im Innern des Steuerknüppel-Gehäuses 8 übertra­ gen werden. Für unterschiedliche Eingaberichtungen an einer mittels eines Kugelgelenkes im Gehäuse 8 gelenkig aufgehängten Handhabe 1 braucht lediglich die um die Handhabe 1 zur Faust geschlossene Hand 4 etwas in die oder gegen die Richtung der Finger- Krümmung verschwenkt zu werden, bevor oder während die Druck- bzw. Zug-Belastung der Handhabe 1 erfolgt.The single figure of the drawing shows a highly abstract side view of how the handle 1 of a joystick 2 structure explained in accordance with the invention no longer protrudes according to the invention from a support surface 3 for the hand 4 of the operator, but rather upside down so far above that now for the hand 4 free support surface 3 hovers that the hand 4 can be placed on the surface 3 in the example shown as a clenched fist with an upright thumb 5 under the holder 10 for the joystick 2 . For orientation when putting down the fist and for support against the lateral pressure exerted on the handle 1 , a bulge 12 protrudes from the support surface 3 . When the fist is placed here, the free front end 6 of the handle 1 should end approximately vertically and preferably slightly inclined towards the vertical, pointing towards the palm of the hand inside the bow of the index finger 7 curved into a fist, while the raised thumb 5 above the front end 6 laterally against the rod-like protruding handle 1 . So from the stick 2 stably mounted under the weight relieved and in the area of the bulge 12 area supported hand 4 by pressing with the thumb 5 or by pulling with the index finger 7 a reproducible bending stress in opposite directions opposite each other Handle 1 evoked and according to the lever-Gege conditions of the handle suspension as a pressure load on the continuously or switching reacting sensors inside the joystick housing 8 are transmitted conditions. For different input directions on a hingedly suspended by means of a ball joint in the housing 8 handle 1, only the to the handle 1 closed fist hand 4 needs something to be pivoted curvature in or against the direction of the finger, before or during the pressure or There is a tensile load on the handle 1 .

Wenn die Handhabe 1 noch weiter in Richtung auf die Auflagefläche 3 hinabragt, dann genügt es sogar, die Handfläche mit leicht nach oben durchgebogenen Fingern hier abzu­ legen und das freie Handhaben-Stirnende 6 zwischen die Gelenke zweier benachbarter Finger einzuklemmen (nicht zeichnerisch dargestellt), um quer zur Längserstreckung der Finger durch Verlagern oder Verkippen der abgestützten Hand Druck auf die Handhabe 1 zu übertragen.If the handle 1 protrudes even further in the direction of the support surface 3 , then it is even sufficient to place the palm of the hand here with slightly bent fingers and to clamp the free end face 6 between the joints of two adjacent fingers (not shown in the drawing), to transmit pressure to the handle 1 transversely to the longitudinal extension of the fingers by moving or tilting the supported hand.

In beiden Fällen ist wichtig für extrem Muskel schwache, daß durch die Auflage unter der Handhabe 1 alles Erfordernis an schwerkraftbedingter Muskelbeanspruchung (zum frei­ schwebenden Halten und gezielten Bewegen der Hand) entfällt und die wenigen noch aufbringbaren Zehntel Millinewton Kraftanstrengung ganz auf die Krafteinleitung in die Handhabe konzentriert werden können, wodurch fast schon Bewegungsunfähige wieder mobil werden.In both cases, it is important for extremely weak muscles that the support under handle 1 eliminates all the need for muscular stress due to gravity (for free-floating holding and targeted movement of the hand) and the few tenths of a millinewton of force that can still be applied entirely to the introduction of force into the handle can be concentrated, which means that people who are almost unable to move become mobile again.

Die Aufnahme 9 für die Handhabe 2, die an der Aufnahme 9 etwa mittels des Gehäuses 8 zwischen einem Flansch und einer Überwurfmutter befestigt ist, kann an einer Halterung 10 ausgebildet sein, die Teil einer zu bedienenden Einrichtung selbst ist und in die des­ halb der Steuerknüppel 2 eingebaut ist. Im skizzierten Ausführungsbeispiel dagegen ist die Halterung 10 für den Steuerknüppel 2 mittels eines separaten, geschwungen aus der Auflagefläche 3 hervortauchenden Ständers 11 oberhalb der Auflagefläche 3 positioniert.The receptacle 9 for the handle 2 , which is attached to the receptacle 9 approximately by means of the housing 8 between a flange and a union nut, can be formed on a holder 10 which is part of a device to be operated and into which the control stick is half 2 is installed. In the outlined embodiment, however, the bracket 10 is separate for the joystick 2 by means of, swinging from the support surface 3 projecting diving stator 11 is positioned above the support surface. 3
