Description

I. Field of application

The invention relates to a control, as known from EP 2 212 755 A with a joystick as commonly used to control the movements of a work machine, particularly a self-propelled work machine.

II. Technical background

The basic function of such a control is first in the pivoting of his joystick to two mutually angled horizontal axes at the bottom of the joystick, so that this pushed forward, pulled backwards and can also be pressed to the left and to the right.

This causes, for example, movements forward or backward or steering movements to the left or right side. The provision of the joystick in the starting position, ie the center position, usually takes place automatically.

Such a joystick is usually held by the operator in the fist, so that either the thumb surrounds the joystick in the upper area or he is on the front of the joystick, while the remaining four fingers surround the joystick and lie on the back.

Since you usually want to control more functions with the joystick, either digital actuators such as push buttons or proportional actuators such as slides are arranged on the front and / or on the back, positioned so that it from one of the on respective front or back resting fingers can be operated without the fist altogether let go of the joystick.

Since the hand holding the joystick can be quite different in size, and the joystick often has to be held by the operator for many hours during operation, it is crucial that the actuators are within easy reach and can be reached without cramping the holding hand.

In order to control by means of the joystick as many other functions by means of the actuators, it has been customary that the controls arranged there such as pushbuttons or slides are each assigned to several functional levels, so can be switched from one function to another.

However, the switching requires either an additional actuator, but in any case a thinking of the operator, on which function the respective actuator is currently set.

III. Presentation of the invention a) Technical task

It is therefore the object of the invention to provide a control with a joystick, which can control as many functions, and yet manages with as few occupancy levels and can be performed comfortably and without cramped attitude by the operator.

b) Solution of the task

This object is solved by the features of claim 1 . Advantageous embodiments will be apparent from the dependent claims.

The object according to the invention is achieved in that, in addition to the first actuating element in the form of a joystick, further, in particular, proportional actuators are arranged on the front side as well as on the back of the joystick and optionally also on one of the side surfaces, preferably in the area of the head and / or in the transition area between the head and the hands of the joystick.

As a result, the number of physically present proportional actuators is sufficiently large, so that the individual actuator no longer needs to be assigned with different functions and switchable, thereby spared the operator to know or get displayed on what function the proportional actuator is currently set.

The same applies to any additional existing digital actuators, such as push buttons, which have a much smaller footprint than proportional actuators, and in addition to these can be arranged between or next to the proportional actuators.

The main problem, however, is the ergonomic arrangement especially of the much space consuming proportional actuators, such as scroll wheels or sliders whose rotation or displacement entails a correspondingly strong adjustment of the thus controlled movement by itself.

For this purpose, viewed in the side view, the front surface of the joystick curved, where it extends at its lower end approximately in the vertical direction - the perpendicular to the flat bottom or top of the base body, and at the same time the direction of the lower part of the shaft - and assumes in its upper end region a frontal angle to the vertical, which is between 45 ° and 75 °, preferably between 53 ° and 65 °.

Viewed from the front view, the center of the middle extending between the two side surfaces on the front surfaces also extends arcuately curved, at its lower end approximately in the direction of the vertical, and runs from there curved upwards to the left, so that they at their upper End occupies a lateral tilt angle to the vertical, which is between 15 ° and 46 ° , preferably between 27 ° and 37 ° .

In order to accommodate the desired number of proportional actuators, at least three such proportional actuators are mounted on the front surface of the joystick in the handle area of the thumb, preferably in a circular arc about a mid-point located in the mid-height range on the front of the joystick and approximately in its center Position corresponds to the thumb joint of the joystick holding hand.

In order to allow a relaxed hand position, the front of the joystick is divided into two and consists of a right thumb, which is usually very weak or not curved at all, and on which there are usually only two proportional actuators in the upper part of this right thumb ,

For right-handed people joins the left thumb on the right thumb surface on the left, on which at least one further proportional actuator is arranged.

These two thumb surfaces are different in that the left thumb surface is one paragraph lower than the right thumb surface, or is tilted to the left rear from the left end edge of the right thumb surface, which corresponds to the natural movement of the thumb from left to right.

In the paragraph in the height range between the two proportional adjacent actuators a substantially along the longitudinal center extending, raised thumb rest is arranged, which protrudes from the front surface and rises higher than the right and left located adjacent proportional actuators. This allows a fatigue-free storage of the thumb, as long as it is not needed.

The proportional actuators on the front surface or generally in the present application are usually either scroll wheels, which project with a part of its circumference slightly over the front surface, so that they can be rotated, or slider, which usually also project something from the mold surface to lighter be taken or moved.

Of course, such components could also be deliberately recessed with respect to the surface in which they are arranged, in order to avoid unintentional actuation while striking over this surface, but then the actuation is made more difficult.

So that the thumb of the hand holding the control stick with his front finger member can reach the above all proportional controls on the front surface, a radial on at least the right hand side protruding hand rest is in the lower part of the stick, ie on the shaft, present in height relative to the joystick adjustable and fixable to hang up on the palm of the hand holding the joystick and hold it at such a height that the thumb the arranged on the front actuators can reach well.

For this purpose, the above all proportional actuators are arranged on the front surface along a circular arc whose center lies approximately in the middle height range of the swivel part, in particular in a hand placed on the correctly adjusted hand rest, in the region of the thumb joint.

At the upper end, the operating end of the joystick, the front surface terminates in an upper edge, the uppermost point of the front surface, in particular of the entire joystick having at its right end, and from there the upper edge of the front surface to the left falls down, in particular arcuately convex curved down.

The direction of movement of the proportional actuators, so scroll wheels or slider, yet differs only by a maximum of a skew angle of + - 20 °, better only from + - 15 °, better only + - 10 ° from the longitudinal center of the along the front surface extending longitudinal center in This height range, as a greater deviation would lead to a cramped thumb position.

On the front surface are - especially in addition - several, in particular 3, digital actuators also in the grip region of the thumb of a pivotal part holding hand arranged. The digital actuators, in particular buttons are preferably arranged below each one of the 3 proportional actuators, so that for the operation of the thumb must be curved, but in this position just pressing a pushbutton is still easily possible in contrast to pressing a slide switch or scroll wheel.

Also on the back surface of the joystick further actuators are arranged:
On the one hand - with respect to the height at the transition from the head to the shaft - in the grip of the middle finger resting on the palm rest and the control stick holding hand first arranged a proportional actuator, wherein the direction of movement is substantially horizontal, so that it by curving and Geradestellen the middle finger can be well operated.

This proportional actuator is preferably located in the upwardly facing flank of a bulge in the rear surface viewed in the side view, thereby causing the middle finger to not slip further down the proportional actuator further.

Preferably, a further digital actuator is arranged above it, which can preferably also be operated with the middle finger, but also possibly with the index finger.

Between both a protruding from the rear surface of the middle finger support is provided, which protrudes further than the two adjacent actuating elements, and has the shape of a transversely, so as about the horizontal, extending web.

There, the middle finger can be stored, as long as it is not needed to operate one of the actuators on the back surface.

In the uppermost area of the rear surface, a bulge is preferably provided, which opens in particular in the right side surface.

This creates below this bulge, in particular in the distance to the underlying digital actuator, a storage channel for a finger, preferably the index finger of the control stick holding hand when it is not needed.

In a joystick according to the invention preferably also in one of the side surfaces - provided in a right-handed joystick in the right side surface -:
Thus, at least one, preferably a plurality of digital actuators are arranged in the right side surface near the upper operating end of the joystick.

These are located on the right side surface preferably closer to the rear surface than on the front surface and have a different distance to the rear surface, but preferably the same distance to the attachment end, as to the end face of the joystick.

Such actuators in the right side surface can be achieved very well with the index finger, which is longer than the thumb, which is why the top actuators in the front surface, preferably the proportional actuators, are set back from the upper end edge of the front surface down.

As a result, the actuators at the upper end of the side surface have the correct position to be actuated by a nearly or fully extended index finger of the holding hand of the joystick.

Of course, in place of a digital actuator there may be arranged additionally or instead one or even two proportional actuators, experience, however, it overstrains the motor of the user when he with two fingers of the same hand different movements, especially different sliding movements in finger longitudinal direction perform should.

The two digital actuators in the side surface are preferably located in each case in a partial region of this side surface, the flanks represent a bulge or the sections at an angle of about 75 ° to 88 °, more preferably from 80 ° to 86 °, to each other.

This opens up to the user alone by the sense of touch of the index finger and the surface inclination around this actuator around which of the two is concerned.

For the arrangement of the joystick according to the invention on a component of the environment, it is essential that the base part, which as a rule comprises a mounting plate and a downwardly projecting part, is formed as flat as possible, so that no deep depression in the female component is needed ,

Preferably, the base body is therefore only a maximum of 3.0 cm high, better at most 2.5 cm high, better only 2.2 cm or even better only a maximum of 1.5 cm.

In order not to overstrain the possibilities of movement and holding forces of the hand 50 , the head of the control stick considered in the side view has a thickness between 5.0 cm and 7.0 cm, more preferably between 5.5 cm and 6.5 cm, measured between the front surface and rear surface.

Viewed on the front surface in the front view, this has at its widest point a width of 7.0 cm to 10.0 cm, better only between 8.0 cm and 9.0 cm.

The control shown in the figures consists of the joystick 1, which according to the Figures 5 and 6 from the operator's hand 50 , and a base body 8 which serves to secure the joystick to a component of the environment and from the top of which the joystick 1 is attached by means of a hinge and projects upwards.

The base member 8 has either a flat top 8 a and / or a flat bottom 8 b, at least on the mounting plate of the base part 8, which serves the screw connection with respect to another component.

This planar upper surface 8 a or 8 b, in this case the plane of the mounting plate, is assumed to be the horizontal plane for the purposes of the present application, since the base body is usually mounted on a horizontal surface.

Similarly, the perpendicular to this flat top or bottom 8 a, b of the base body 8 is defined as a vertical 10 .

The joystick 1 is pivotally mounted on the upper side of the base body 8 pivotally about two mutually angled and preferably lying in the horizontal pivot axes 2 a, b, wherein the relevant joint is arranged in a conventional rubber bellows 27 .

These two Verschwenkungsrichtungen of the joystick 1 represent the first two proportional actuation options, because this two movement functions of a working device can be controlled, for example, forward or backward movement and deflection to the left or right.

For many machines to be controlled with such a joystick, however, a much larger number of proportional as well as digital control options is necessary, which is why on the joystick a variety of such actuators are housed with the fingers of the joystick 1 holding the hand of a user - as in the Figures 5 and 6 shown - can be operated.

For this purpose, the control stick 1 has a base body 8 towering, relatively narrow, shaft 11, which widened to the operating end 1 b of the joystick 1 towards a head 9 , so especially on the widened in the head 9 thereby front surface 4 of the Joystick 1 several more actuators can be accommodated:
In order for the actuation of these fingers of the user's hand are in the correct position , a hand rest 7 is attached to the shaft 11 at the lower end, near the operating end 1 a of the joystick 1 , which at least on one side, for a right-handed the right side, radially projecting from the shaft 11 , as best in Fig. 1b and 4a to recognize:
Then, the user's hand leading the joystick can be placed with the narrow side of the palm opposite the thumb, and the hand rest 7 in the longitudinal direction, ie substantially in the direction of the vertical 10 along the shaft 11 adjustable and to adapt to the size of this hand lockable, for example by loosening or tightening a clamping screw in the ring-shaped hand rest 7th

The joystick 1 is held in the operation of the user's hand 50 in a staple grip, so that only the thumb on the front surface 4 of the joystick 1, in particular the head 9, is located.

To allow a natural, fatigue-free attitude of the leading hand 50 , the joystick 1 and thus also its front surface 4 is not straight, but bent in several directions:
As Fig. 4a can be seen in the side view, the front surface 4 at the lower end of the shaft 11 is still aligned vertically or approximately vertically, and extends from there convexly arcuate, so that the front surface 4 at the attachment end 1 b relative to the vertical 10 a front surface angle 16 of about 53 ° to 65 ° occupies, and this angle remains approximately over the entire extent of the head 9 , by the front-side actuators are.

How best Fig. 1a shows the joystick 1 viewed in the front view not straight up, but is - the present joystick is designed for a right-handed, for a left-hander, it would be exactly the opposite - curved from the mounting end 1 a from the top left.

Is drawn on the center of the front surface 4 a longitudinal center 4 ' , from the center at the operating end 1 b to the center at the attachment end 1 a in the Front view is sufficient, this longitudinal center 4 'is at the upper end of the front surface 4 at a lateral inclination angle 19 of 27 ° to 37 ° to the vertical 10th

The upper end edge of the front surface 4 is also designed convex arcuate, so that its highest top point 17 is located at the right end of this end edge and it drops from there to the left arcuately.

In the supervision of the Fig. 1a and viewed also further front views, the pivoting part 1 is thus designed approximately pear-shaped, with the front surface 4, the side surfaces 6 a, b and the back surface 5 merge into each other in only slightly rounded edges, but this is not a condition for the features of this control stick invention.

In the present drawings are as proportional actuators scroll wheels - ie wheels whose axis of rotation are below the surface, in this case the front surface 4, and preferably projecting out of this and twisted - drawn or merely the receiving opening for such a proportional actuator in Housing of the swivel part 1, and as digital actuators pushbuttons.

In order to accommodate as many actuators, three proportional actuators 3 a, b are arranged on the front surface 4 , each near the upper end of the front surface, and with their orientation, ie their direction of movement 14, not parallel to each other but in an upwardly opening Corner.

The direction of movement 14 of the left proportional actuator 3 a is in an oblique angle 21 of about 10 ° to 20 ° to the longitudinal center 4 'of the front surface . 4

The centers of the proportional actuators 3 a, b, c are arranged on a circular arc 12 , the center 14 sits approximately in the region of the transition between the head 9 and shaft 11 , ie at a the joystick 1 leading hand 50 of the user approximately in the region of the thumb joint , When the thumb is stretched out, it is thus optionally located on one of the proportional actuators 3 a, b, c.

Below each of the three proportional actuators 3 a, b, c is in each case a digital actuator 13 a, b, c arranged so that the thumb for actuating these digital actuators 13 a, b, c must be curved.

In addition, the left part of the front surface 4, the left thumb surface 4 a, is set lower than in relation to the right thumb surface 4 b, in which there are two proportional and digital actuators, since this is easier for the operation by the thumb.

In the paragraph 22 between, and in the area between the first and second proportional actuator 3 a and 3 b protrudes from the front surface 4, a thumb rest 23 in the form of a raised, approximately in the longitudinal center 4 ' extending web up, and indeed as the adjacent actuators protrude upwards.

The thumb must therefore not be held rigidly in the air when not in use, but can be placed specifically on the thumb rest 23 to prevent fatigue.

How best that FIGS. 2a . b . c 1, further actuating elements are accommodated on the back surface 5 of the control stick 1. First, a proportional actuating element 3 d whose direction of movement 14 is arranged approximately horizontally and which is in the lower region of the head 9, ie almost in the transition to the shaft 11 .

As Fig. 3a shows, the rear surface 5 of the joystick 1 is approximately parallel to the front surface 4, so that the thickness of the joystick 1 only slightly widened from the lower mounting end 1 a to the upper actuating end 1 b.

As Fig. 3a can also be seen, is the said proportional actuator 3 d in the upward-facing edge of a bulge 26 in the rear surface 5, which interrupts the otherwise concave contour of the rear surface 5 in the side view by its convex shape. As a result, the middle finger 53, which should operate this proportional actuator 3 d - as best in Fig. 6 a to recognize - placed there without cramping and moved.

In the distance above it is - see Fig. 2a - Another digital actuator 13 d arranged, which preferably also from the middle finger 53 - see Fig. 6 a . b - Can be operated, but also by the index finger 52.

Between the two actuators is a middle finger tray 24 in the form of extending approximately in the horizontal direction, bulging from the back surface 5 web, which is more highly arched than the adjacent two actuators 13 d and 3 d and as a relaxed storage for not used middle finger 53 or index finger 52 is used.

In addition, in this joystick in the - for right-handed - right side surface 6 b actuators housed, which can be reached and operated by the extended upwardly pointing index finger 52 :
How best in Fig. 2b . c and Fig. 3a can be seen, there are two digital actuators 13 e, 13 f, which are arranged near the upper end of the side surface 6 b and close to the rear surface 5 side by side are, so that one is arranged almost immediately adjacent to the rear surface 5 , the other a little further towards the front surface . 4

These two pushbuttons 13 e, f are arranged on portions 6 b 1 , 6 b 2 of the side surface 6 b, which are in an outer angle 29 of about 185 ° to 215 °, better 195 ° to 209 ° to each other, which is the distinctness of both push buttons sensor-facilitated by the operator alone.

In the Figures 5 and 6 In addition, the hand leading the joystick is additionally drawn:
As Fig. 5a . b illustrated with the direction of view from the front, the user's hand 50 surrounds at least with the middle finger, ring finger and little finger the shaft 11 of the control stick of 1, and lies with the palm on the top of the hand pad 7 .

In FIG. 5a the thumb on the front actuates the right proportional actuator 3 c or the underlying digital actuator 13 c, in FIG. 5 b In contrast, the left digital actuator 13 a.

In the FIGS. 6a -d are various hand postures viewed from the back of the joystick 1 :
In FIG. 6a encircle ring finger and little finger the shaft 11, while the middle finger 53 is located on the rear proportional actuator 13 d and can operate this. The index finger 52 is located on the rear digital actuator 13 d and can operate this.

In FIG. 6b However, ring finger and index finger 52 also enclose the shaft 11, the middle finger 53 is now stored on the middle finger pad 24 of the back, and is inactive, while the index finger 52 in the storage channel 28 on the back, between the back digital Actuator 13 d and the spaced-apart buckle 25 which is formed for the lateral digital actuator 13 f.

In FIG. 6c differs the hand position opposite FIG. 6b in that here the index finger curved actuates the digital actuator 13 f, which is arranged in the upper region of the side surface 6 b.

In FIG. 6d Hand posture of middle finger 53 and index finger 52 is different again by the middle finger 53 is located on the rear digital actuator 13 d, while the index finger 52 is the arranged on the side surface 6 b, further forward of the two digital actuators 13 e, f to press.
