Switching levers, which can be actuated by moving the hand with an immovable arm, are provided as actuators which can be gripped by hand. It is also known to move the shift lever in two vertical directions, whereby several shift channels can be controlled. The actuation of the actuating levers takes place proportionally along two mutually perpendicular flat arcs, being approximately parallel to the plane receptacle during operation in a plane.

Aus der GB-A-2 201 758 ist eine mit einer Armlehne verbundene Stelleinrichtung bekanntgeworden, bei der eine Schwenkachse für ein Griffelement, das von der Hand bei Auflage des Arms auf der Armauflage übergriffen wird, im Bereich des Handgelenks liegt, wenn die Hand das Griffelement erfaßt.From GB-A-2 201 758 an actuator connected to an armrest has become known, in which a pivot axis for a grip element which is overlapped by the hand when the arm is placed on the armrest lies in the region of the wrist when the hand does so Grip element detected.

Aus der EP-A-0 503 801 ist eine Stellvorrichtung für Flurförderfahrzeuge bekanntgeworden, bei der ebenfalls seitlich des Bedienungssitzes eine Auflage für den Unterarm und vor der Unterarmauflage ein von Hand ergreifbares Stellorgan vorgesehen ist, das zwischen Handballen und Finger von der Hand erfaßt werden kann. Seitlich ist ein Druckknopf zur Betätigung mit Hilfe des Daumens vorgesehen. Das Stellorgan wird mittels einer Stange in einem Steuergehäuse geführt und kann sowohl eine translatorische als auch rotatorische Bewegung ausführen.From EP-A-0 503 801 an adjusting device for industrial trucks has become known, in which a support for the forearm is also provided on the side of the operating seat and a hand-held actuator is provided in front of the forearm support, which can be gripped by hand between the ball of the hand and the finger . A push button is provided on the side for actuation using the thumb. The actuator is guided in a control housing by means of a rod and can carry out both a translatory and a rotary movement.

Aus der EP-A-0 453 587 ist eine sogenannte Computermaus bekanntgeworden, die zwischen Handballen und Finger sich erstreckend von der Hand übergreifbar und ballig ausgeformt ist zur Anpassung an die Handinnenfläche. Die Computermaus weist mehrere Schalttasten auf, die auf der dem Unterarm gegenüberliegenden Seite angeordnet sind.From EP-A-0 453 587 a so-called computer mouse has become known, which is located between the ball of the hand and the finger can be gripped by the hand and has a spherical shape to adapt to the palm of the hand. The computer mouse has a plurality of switch buttons which are arranged on the side opposite the forearm.

Der Erfindung liegt die Aufgabe zugrunde, eine handbetätigte Stellvorrichtung für einen Bedienungssitz, insbesondere für Förderzeuge, zu schaffen, die eine feinfühlige Steuerung ermöglicht, ohne daß beim Bediener nach längerer Zeit Verkrampfungen oder Folgeschäden auftreten. Ferner soll sie problemlos innerhalb der ergonomischen Grenzen genutzt werden können.The invention has for its object to provide a manually operated control device for an operator seat, in particular for conveyors, which enables sensitive control without cramping or consequential damage to the operator after a long time. Furthermore, it should be easy to use within the ergonomic limits.

Diese Aufgabe wird erfindungsgemäß gelöst durch die Merkmale des Patentanspruchs 1.This object is achieved according to the invention by the features of patent claim 1.

Bei der erfindungsgemäßen Stellvorrichtung ist ein schildförmiges balliges Griffelement vorgesehen, das von Hand übergriffen werden kann und dabei zwischen den Fingern und dem Handballen liegt. Alternativ kann es auch zwischen Daumen und Fingern erfaßt werden. Seine Höhe oberhalb der Auflage ist derart, daß es beim Aufliegen des Unterarms auf der Auflage bequem von Hand übergriffen werden kann. Das Griffelement ist in geeigneter Weise annähernd in einer Ebene geführt derart, daß es im wesentlichen aus den Fingergelenken und/oder aus dem Handgelenk heraus betätigbar ist. Die Führungsebene ist parallel zur ebenen Auflagefläche.In the actuating device according to the invention, a shield-shaped spherical grip element is provided which can be gripped by hand and thereby lies between the fingers and the ball of the hand. Alternatively, it can also be gripped between the thumb and fingers. Its height above the support is such that it can be easily gripped by hand when the forearm rests on the support. The handle element is approximately in a suitable manner guided in a plane such that it can be actuated essentially from the finger joints and / or from the wrist. The management level is parallel to the level contact surface.

Am Griffelement ist mindestens eine Schalttaste oder dergleichen angeordnet, die auf der dem Unterarm gegenüberliegenden Seite des Griffelements angeordnet ist.At least one switch button or the like is arranged on the grip element and is arranged on the side of the grip element opposite the forearm.

Bei der erfindungsgemäßen Stellvorrichtung ist das Griffelement die Schnittstelle zur menschlichen Hand. Es kann nach einer Ausgestaltung der Erfindung auf gegenüberliegenden Seiten seitliche Vertiefungen aufweisen, in die der Daumen bzw. Ringfinger/kleiner Finger eingreifen können. Die Bewegung des Griffelements wird vornehmlich durch Finger bzw. Handgelenkdrehung ausgeführt (Feinsteuerung). Die Bewegung kann ebenso gut durch vollflächiges Auflegen der Hand und Verschieben des ganzen Arms erzeugt werden (Grobsteuerung, zum Beispiel volle Geschwindigkeit). Dadurch ist ein Wechsel der Handhaltung möglich und eine statische Haltung der Hand vermieden. Bei einer balligen Grundform kann das erfindungsgemäße Griffelement an die Handinnenfläche von 5.Perzentil Frau bis 95.Perzentil Mann angepaßt sein. Dabei ist das Griffelement nur so hoch, daß bei aufliegendem Unterarm die Hand über dem Griffelement liegt.In the actuating device according to the invention, the grip element is the interface to the human hand. According to one embodiment of the invention, it can have lateral depressions on opposite sides, into which the thumb or ring finger / little finger can engage. The movement of the grip element is mainly carried out by turning the finger or wrist (fine control). The movement can also be generated by laying the hand on the entire surface and shifting the whole arm (rough control, for example full speed). This makes it possible to change the hand position and avoid a static hand position. In the case of a spherical basic shape, the grip element according to the invention can be adapted to the palm of the hand from the 5th percentile to the 95th percentile man. The grip element is only so high that the hand is above the grip element when the forearm is resting on it.

Mit einem Griffelement nach der Erfindung lassen sich vier analoge Kanäle feinfühlig steuern, wobei das Griffelement Schalttasten oder dergleichen enthält, um weitere digitale Kanäle zu schalten. Das Griffelement ermöglicht Bewegungen und Belastungen des Bedieners innerhalb ergonomisch zulässiger Grenzen. Eine Einwirkung auf das Griffelement durch den Bediener aufgrund von dynamischen Kräften, die aus beliebigen Richtungen (Bremsen, Beschleunigen usw.) auf seinen Körper wirken, findet nicht statt. Auch eine Benutzung über einen längeren Zeitraum führt beim Bediener nicht zu Verkrampfungen oder Folgeschäden am Bewegungsapparat.With a handle element according to the invention, four analog channels can be controlled sensitively, the handle element containing switching buttons or the like in order to switch further digital channels. The handle element enables movements and loads on the operator within ergonomically permissible limits. The operator has no influence on the handle element due to dynamic forces acting on his body from any direction (braking, accelerating, etc.). Even use over a longer period of time does not cause cramps or consequential damage to the musculoskeletal system.

Bei der erfindungsgemäßen Stellvorrichtung ist das Griffelement so gestaltet, daß die Unterarmauflage das Armgewicht auffängt und den Oberkörper gegen quer zur Körperachse angreifende dynamische Kräfte abstützt.In the adjusting device according to the invention, the grip element is designed so that the forearm support absorbs the arm weight and supports the upper body against dynamic forces acting transversely to the body axis.

Das erfindungsgemäße Griffelement kann für die unbekleidete Hand ebenso verwendet werden wie für eine Hand mit Arbeitshandschuh. Eine allzu genaue Fixierung der Hand an dem Griffelement ist nicht erforderlich, so daß Verkrampfungen vermieden werden.The grip element according to the invention can be used for the bare hand as well as for a hand with work gloves. A too precise fixation of the hand on the grip element is not necessary, so that cramping is avoided.

Bei der Erfindung liegt eine Schwenkachse für das Griffelement etwa im Bereich des Handgelenks, wenn die Hand das Griffelement erfaßt. Dadurch kann das Griffelement besonders leicht aus dem Handgelenk heraus und mit den Fingern bewegt werden. Es werden mithin feinmotorische Gliedmaßen zur Steuerung herangezogen. Wie schon erwähnt, ist es jedoch nicht ausgeschlossen, das Griffelement auch im Zufassungsgriff der hohlen Hand zu halten und aus der Bewegung des gesamten Arms zu bewegen.In the invention, a pivot axis for the grip element lies approximately in the area of the wrist when the hand grips the grip element. This makes it particularly easy to move the grip element out of the wrist and with your fingers. Fine motor limbs are therefore used for control. However, as already mentioned, it is not impossible to hold the grip element in the grip grip of the hollow hand and to move it from the movement of the entire arm.

Um vier analoge Kanäle steuern zu können, ist eine Bewegung des Griffelements in der Ebene erforderlich. Zu diesem Zweck sieht eine Ausgestaltung der Erfindung vor, daß die Führung ein Langloch und einen Zapfen aufweist, die relativ zueinander beweglich gelagert sind, wobei das Langloch im wesentlichen in der Längsrichtung des Unterarms liegt. Das Griffelement ist zu diesem Zweck nach einer Ausgestaltung der Erfindung mit einem Führungselement unterhalb der Auflage verbunden, das mittels ortsfester Führungsabschnitte bzw. -flächen in einer Ebene geführt ist. Vorzugsweise wird das Führungselement von einer Führungsplatte gebildet, die nach einer weiteren Ausgestaltung der Erfindung kreuzförmig sein kann. Vorzugsweise erfolgt die Bewegung des Griffelements mit der Führung in einer horizontalen Ebene. Dadurch können das Arm- und Handgewicht aufgenommen werden, so daß die Armmuskulatur nur durch die Steueraufgabe beansprucht ist und keine überlagerte statische Haltespannung auftritt. Wie erwähnt, kann die Vor- und Rückbewegung entlang einer geraden Bahn verlaufen. Eine vorgegebene Bahn kann jedoch je nach den Anforderungen auch gekrümmt sein.In order to be able to control four analog channels, a movement of the handle element in the plane is required. For this purpose, an embodiment of the invention provides that the guide has an elongated hole and a pin which are mounted so as to be movable relative to one another, the elongated hole lying essentially in the longitudinal direction of the forearm. For this purpose, according to an embodiment of the invention, the grip element is connected to a guide element below the support, which is guided in one plane by means of stationary guide sections or surfaces. The guide element is preferably formed by a guide plate which, according to a further embodiment of the invention, can be cross-shaped. The movement of the grip element with the guide preferably takes place in a horizontal plane. This allows the arm and Hand weight are taken so that the arm muscles are only used by the control task and no superimposed static holding voltage occurs. As mentioned, the forward and backward movement can be along a straight path. However, a given path can also be curved depending on the requirements.

Es verseht sich, daß auch andere Führungen verwendet werden können, um eine Steuerung über vier analoge Kanäle vornehmen zu können, z.B. sogenannte Kreuztischführungen oder dergleichen.It will be appreciated that other guides can be used to control four analog channels, e.g. so-called cross table tours or the like.

Die Links-Rechtsbewegung beschreibt einen Kreisbogen, dessen Mittelpunkt etwa dem des Handgelenkdrehpunktes entspricht. Zu diesem Zweck kann nach einer Ausgestaltung der Erfindung zwischen dem Führungselement und der Unterseite des Griffelements ein Verbindungszapfen vorgesehen sein, der sich durch eine vorzugsweise kreisförmige Öffnung mit einem größeren Durchmesser als der des Zapfens hindurcherstreckt. Die Größe und Form der Öffnung bestimmt mithin die Größe und Form der Bewegungsfläche für das erfindungsgemäße Griffelement.The left-right movement describes a circular arc, the center of which corresponds approximately to that of the wrist pivot. For this purpose, according to an embodiment of the invention, a connecting pin can be provided between the guide element and the underside of the handle element, which extends through a preferably circular opening with a larger diameter than that of the pin. The size and shape of the opening therefore determines the size and shape of the movement surface for the grip element according to the invention.

Nach einer anderen Ausgestaltung der Erfindung ist das Griffelement begrenzt höhenverstellbar gelagert zur Erzeugung eines weiteren Stellsignals, beispielsweise eines Hupsignals.According to another embodiment of the invention, the handle element is mounted to produce a limited height a further control signal, for example a horn signal.

Es ist ohne weiteres möglich, mehrere erfindungsgemäße Griffelemente nebeneinander anzuordnen ohne Nachteile für den Zugriff und die Betätigung. Das erfindungsgemäße Griffelement ist im übrigen sowohl für die rechte als auch für die linke Hand einsetzbar. Darüber hinaus kann es in seiner Ausformung der menschlichen Hand oder auch an andere Gegebenheiten angepaßt sein. Es ist, wie bereits erwähnt, bei gleicher Baugröße auch von einer mit Arbeitshandschuhen bekleideten Hand bedienbar. Da das erfindungsgemäße Griffelement ein flaches gewölbtes Bauteil auf einer ebenen Fläche ist, ist eine ungewollte Betätigung, zum Beispiel durch Hängenbleiben mit dem Ärmel, auszuschließen.It is easily possible to arrange several grip elements according to the invention next to one another without disadvantages for access and operation. The grip element according to the invention can also be used for both the right and the left hand. In addition, its shape can be adapted to the human hand or to other circumstances. As already mentioned, it can also be operated from a hand wearing work gloves, with the same size. Since the grip element according to the invention is a flat, curved component on a flat surface, unwanted actuation, for example by getting caught with the sleeve, can be ruled out.

Zu diesem Zweck ist eine Führung vorgesehen, die anhand der Figuren 3 bis 6 näher erläutert werden soll.The grip element 10 can be moved to a limited extent in one plane, preferably a horizontal plane, the axes of which are shown in dash-dot lines at 30 and 32 in FIG. 2. From the broad arrows shown in Fig. 2 it can be seen that the handle element 10 can be pivoted in a straight line back and forth and / or to the side. For this purpose, a guide is provided, which will be explained in more detail with reference to FIGS. 3 to 6.

In Fig. 3 ist eine horizontale, ebene Auflage 34 für den Unterarm des Bedieners gezeigt, die eine Öffnung aufweist, über die das Griffelement 10 mit einer Führung 36 verbunden ist, und zwar über zwei Zapfen 38, 40. Die Führung 36 weist ein Gehäuse 42 auf, das von einem Deckel 44 verschlossen ist. Im Deckel 44, der in Fig. 6 aus Darstellungsgründen durchsichtig gezeichnet ist, sind zwei kreisförmige Öffnungen 46, 48 vorgesehen, durch die sich die Zapfen 38, 40 hindurcherstrecken. Wie aus Fig. 6 erkennbar, ist der Durchmesser der Zapfen 38, 40 erheblich kleiner als der Durchmesser der Öffnungen 46, 48.3 shows a horizontal, level support 34 for the forearm of the operator, which has an opening via which the grip element 10 is connected to a guide 36, specifically via two pins 38, 40. The guide 36 has a housing 42, which is closed by a cover 44. In the cover 44, which is drawn transparently in FIG. 6 for reasons of illustration, two circular openings 46, 48 are provided through which the Extend pin 38, 40 through. As can be seen from FIG. 6, the diameter of the pins 38, 40 is considerably smaller than the diameter of the openings 46, 48.

Im Gehäuse 42 befindet sich eine kreuzförmige Führungsplatte 50. Sie ist oben durch den Deckel 44 und unten durch geeignete Führungsflächen annähernd spielfrei horizontal geführt. Die Arme 52, 54, 56 und 58 erstrecken sich durch entsprechende Öffnungen des Gehäuses 42 nach außen. Sie können mit Signalwandlern verbunden werden (nicht gezeigt). In Fig. 3 ist gezeigt, wie nach unten aus dem Gehäuse 42 eine Stange 60 heraussteht, die mit einem Signalwandler 62 verbunden ist zur Umwandlung der Verstellwege bzw. -positionen des Griffelements 10 in geeignete Stellsignale. Im Arm 52 ist ein Langloch 64 geformt, durch den sich ein gehäusefester Zapfen 66 hindurcherstreckt. Der Zapfen 66 ermöglicht eine geradlinige Bewegung des Griffelements 10. Die durch den Zapfen 66 und das Langloch 64 gebildete Schwenkverbindung liegt etwa in Übereinstimmung mit dem Handgelenk des Bedieners. Die maximalen Verstellbewegungen der Führungsplatte 50 sind begrenzt durch die kreisförmigen Öffnungen 46, 48 in der Deckplatte 44. In Fig. 6 sind verschiedene Positionen der Führungsplatte 50 in punktierten Linien angedeutet.A cross-shaped guide plate 50 is located in the housing 42. It is guided horizontally almost without play at the top through the cover 44 and at the bottom through suitable guide surfaces. The arms 52, 54, 56 and 58 extend through corresponding openings in the housing 42 to the outside. They can be connected to signal converters (not shown). 3 shows how a rod 60 protrudes downward from the housing 42 and is connected to a signal converter 62 for converting the adjustment paths or positions of the grip element 10 into suitable actuating signals. An elongated hole 64 is formed in the arm 52, through which a pin 66 fixed to the housing extends. The pin 66 enables the handle element 10 to move in a straight line. The pivot connection formed by the pin 66 and the elongated hole 64 is approximately in agreement with the operator's wrist. The maximum adjustment movements of the guide plate 50 are limited by the circular openings 46, 48 in the cover plate 44. In FIG. 6, different positions of the guide plate 50 are indicated in dotted lines.

In Fig. 7 ist zu erkennen, wie der Unterarm eines Bedieners auf der Auflage 34 ruht, oberhalb der drei Griffelemente 10, 10a und 10b von identischem Aufbau angeordnet sind, wobei ihre Unterseite (Fig. 3) sich nur minimal oberhalb der Oberfläche der Auflage 34 befindet. Die Griffelemente 10, 10a, 10b liegen auf einem Kreisbogen, dessen Mittelpunkt annähernd im Ellbogengelenk des Bedieners liegt. Mit Hilfe der drei Griffelemente kann eine hohe Anzahl von analogen Kanälen bedient werden. Das Griffelement 10 kann zum Beispiel auch höhenverstellbar gelagert sein zur Auslösung eines digitalen Signals beim Herabdrücken des Griffelements, beispielsweise eines Hupsignals.In Fig. 7 it can be seen how the forearm of an operator rests on the support 34, above which three handle elements 10, 10a and 10b of identical construction are arranged, their underside (Fig. 3) being only slightly above the surface of the support 34 is located. The grip elements 10, 10a, 10b lie on a circular arc, the center of which lies approximately in the elbow joint of the operator. With the help of the three handle elements, a large number of analog channels can be operated. For example, the handle element 10 can also be height-adjustable to trigger a digital signal when the handle element is pressed down, for example a horn signal.

Das Griffelement 10 ist aus einem geeigneten Kunststoffmaterial geformt, kann Jedoch auch aus Metall oder Holz bestehen.The grip element 10 is formed from a suitable plastic material, but can also consist of metal or wood.

Die gezeigte Verstellvorrichtung ist für die verschiedensten Bedienungsstände und Bedienungsplätze geeignet, insbesondere als Stellvorrichtung für Steuerventile eines Förderfahrzeugs und hier wiederum insbesondere für einen Schubmaststapler. Es versteht sich jedoch, daß auch andere Fahrzeuge und auch mehr oder weniger stationäre Förderzeuge mit der erfindungsgemäßen Stellvorrichtung gesteuert werden können, zum Beispiel Kräne, Bagger und dergleichen.The adjusting device shown is suitable for a wide variety of operating positions and operating positions, in particular as an adjusting device for control valves of a conveyor vehicle and here again in particular for a reach truck. However, it goes without saying that other vehicles and also more or less stationary conveyors are controlled with the actuating device according to the invention such as cranes, excavators and the like.

Es versteht sich, daß dem Griffelement bzw. der Führung ein Federmechanismus zugeordnet ist, um das Griffelement in der Neutralstellung zu halten und in diese nach Betätigung zurückzubringen.It is understood that a spring mechanism is assigned to the handle element or the guide in order to hold the handle element in the neutral position and to return it to it after actuation.
