A sensor integrated in the GD offers ergonomic improvement so that the user's hand rests on it in a position, in which a metacarpus (19b) with a support encompasses an angle of less than 45[deg] and, for each second to fifth fingers, a main phalanx (19c) and the metacarpus encompass an angle between 120[deg] and 130[deg].

Description

The The invention relates to a device for converting a hand movement in an electrical signal sequence, in particular a pointing device for one Computer ("mouse") after the generic term of claim 1.

Such pointing devices (computer mice) are used to control movements of a symbol ("cursor") on a computer screen. The use of such computer mice burdens the hand and forearm muscles. Static handling and small goal-oriented movements create a high tension of the musculature. In the conventional mouse, these stresses are due to the extended position of the fingers 2 - 5 (Index finger, middle finger, ring finger and little finger) even stronger. Both the flexor muscles and the extensor muscles of the hand must perform physiological hard work when operating the mouse in the extended position, which is also recognized by the fact that the hand has the least power in this position.

By this unphysiological overuse It can come to hand disease, with the pain typically migrates from the bottom to the top, where at the spine between cervical vertebrae C5 and thoracic vertebrae T1 arise exactly the nerves. The pain wanders from the hand to the forearm and from there over the upper arm and shoulder to the Move. Do not work with the mouse, the complaints are better, but return by the memory of the cells after work recovery rapidly and even intensified back.

Out DE 202 12 753 U1 there is known a so-called ergonomic mouse device for use on a work surface, the device comprising a housing comprising: a bottom adapted to be placed on the work surface; at least one finger-operated pointing element; and an upper surface having an elevation for contacting a palm area of the palm of a user's hand substantially at the metacarpal-phalangeal joint of the second finger and at least a portion of the metacarpal-phalangeal joint of the third finger, the elevation having a higher height as the remaining portions of the upper surface relative to the lower surface, the upper surface extending downward from the elevation in a forward direction toward the tips of the second and third fingers to form a forward portion, in a rearward direction toward the user's wrist downwardly to form a rear portion and extending downwardly in an outward direction toward the metacarpal phalanges of the fourth and fifth fingers to form an outer portion, the rear portion being formed so as to extend from the ball of the thumb of the palm surface is arranged outwardly in order to avoid supporting the ball of the thumb area substantially.

Out DE 201 10 241 U1 For example, there is known a computer mouse having an orthopedic shape comprising a base portion comprising the actuators and the scanner, which is provided with connection means for receiving a hand support portion which, in the back of the mouse following a palm contours, supports the user's handball as mouse-gliding support , includes.

The However, devices according to the prior art have the disadvantage that they still do not sufficiently relieve the user from a physiological point of view and longer Working with them can still lead to tension.

task Therefore, it is an ergonomic feature of the present invention improved device (computer mouse) for converting a hand movement to create in an electrical signal sequence, which front the user Malpositioning of the hand and thus early fatigue when working with one protects such device.

These The object is achieved by the device for converting a hand movement into an electrical Signal sequence according to claim 1. Preferred embodiments of the invention are the subject of the dependent claims.

The inventive device (Mouse) is anatomically physiologically shaped so that the discomfort, as they usually do after an unnatural hand gesture over a longer Duration often are no longer occurring. This is achieved by the fact that Mouse is operated out of the working position of the hand. The Function position is for the daily accumulating Working the hand the most appropriate position.

The inventive device for converting a hand movement in an electrical signal sequence, in particular computer mouse, with a handle device on which rests the hand of a user and which is movable on a base, a sensor which is integrated in the handle device and the electrical signal sequence in Dependent on the direction of movement and the speed of movement generated, and at least one Schalterein direction, which is integrated in the gripping device and with which a switching operation can be triggered, characterized in that the gripping device is formed by corresponding support surfaces so that the user's hand rests in a position on it, in the middle hand with the pad a Angle of less than 45 ° (preferably about 30 °) and includes - for the second, third, fourth and fifth finger - the metacarpal and the finger base include an angle between substantially 120 ° and 130 °, the finger base and the finger middle member one Include flexion angles between substantially 150 ° and 170 ° and include the finger middle member and the finger end member a flexion angle between substantially 150 ° and 170 °.

In addition, preferred embodiments of the invention have one or more of the following features in combination, so that in the device preferably:
the gripping device has a transverse extension transverse to the flexion axis of the hand, in which the metacarp assumes a convex shape in the region of the attachment of forefinger, middle finger, ring finger and small finger;
a first switch means is provided, the first switch means having a switching path from bottom to top with respect to the pad;
a second switch means is provided, wherein the second switch means comprises a switching path from the front bottom obliquely rear top of the pad away towards the center hand;

One Advantage of the invention is that the hand in use the device can always remain in its rest position, so that the musculature also with longer ones activity not overused becomes. Thereby can even after a long time Work with the device the fine movements are being performed with which, for example, an exact adjustment of a pointer a computer screen is made.

in the Following, the invention with reference to the in the drawing in more schematic Illustrated embodiments explained in more detail. It demonstrate:

1 the inner surface of a right hand;

2 the right hand from the left side;

3A to 3D the right hand from the left side or from above with different diffraction of the fingers, each with the direction of force of least effort;

4 the usual position of the hand in a device according to the prior art;

5A , B, C, D bis 11A , B, C, D are each an embodiment of the invention from the left, top, front and rear.

1 shows the inside surface of a right hand 1 with a thumb 2 , a second finger 3 (Index finger), a third finger 4 (Middle finger), a fourth finger 5 (Ring finger) and a fifth finger 6 (pinkie finger). The essential areas of the hand relieved by the invention are:
the thumb basic element 7 .
the thumb end member 8th .
the basic link 9 the second, third, fourth and fifth fingers,
the middle link 10 the second, third, fourth and fifth fingers,
the end member 11 the second, third, fourth and fifth fingers,
the distal interphalangeal joint (DIP) 12 .
the proximal interphalangeal joint (PIP) 13 .
the finger base joint (MP joint) 14 .
the ball of the thumb (Thenar) 15 .
the little fingerballen (Hypothenar) 16 .
and the middle-hand well 17 ,

2 shows the right hand from the left side with the angles that the individual finger members of the second finger enclose with each other when the hand is in a rest position and relaxed. These angles apply correspondingly to the third, fourth and fifth fingers. For clarity, the lines are as auxiliary lines 19a to 19d located.

In the resting position, the forearm is flat on a plane, ie, the (sagittal) axis 19a through the forearm is horizontal. The middle hand 18 is placed slightly upwards, so that the forearm axis 19a with the obliquely upward axis 19b the middle hand 18 forms an angle which is substantially 150 ° in the rest position or functional position of the hand, but does not fall below 135 °. The better clarity is instead of this angle its complementary angle α in 2 drawn, which is 30 °, but does not exceed 45 °.

The middle hand 18 closes with the base member 9 of the second to fifth fingers 3 to 6 an angle between substantially 120 ° and 130 °. For the sake of clarity, is in 2 its complementary angle β between the two auxiliary lines 19b for the middle hand 18 and 19c for the finger basic element 9 drawn, which is correspondingly between 50 ° and 60 °. The finger basic element 9 and the finger middle link 10 in turn include a deflection angle between substantially 150 ° and 170 °. Again, for the sake of clarity, the complementary angle γ between the axis 19c of the finger basic element 9 and the axis 19d of the finger middle link 10 located. The complementary angle γ is correspondingly between 20 ° and 30 °. Finally form the finger middle link 10 and the finger tip 11 a bending angle of substantially 150 ° to 170 °. The corresponding complementary angle δ between the two auxiliary lines 19d for the finger middle link 10 and 19e for the finger end member 11 is also between 20 ° and 30 °.

The hand in 2 is shown in the functional position, in which the fingers take a slightly curved position and in which the muscles are relaxed. 3A , B, C show the right hand from the left side, each with differently curved fingers two to five. Depending on the degree of flexion, a force can be exerted in different directions with the fingers. Thus, in the attitude of the hand in 3A a force 20 exercised, which is substantially horizontal. For slightly more bent fingers, as in 3B is shown, the force passes 21 which is exerted by the finger-end member, diagonally upward with respect to a pad (not shown) on which the hand rests. In 3C Finally, the fingers of the hand are even more curved, so the force 22 , which is optimally exerted by the finger tip, is directed vertically upwards.

3D shows the right hand from above. Here the direction is marked, in which with the thumb a force can be exercised optimally, without thereby it comes to a tension of the hand. This power 23 also runs horizontally as in 3A but this time in a direction transverse to the axis (not shown) 19a of the forearm.

From the in 3A , B, C and D shown "natural" and relaxed positions of the hand deviates the attitude of the hand, which must be taken in a mouse according to the prior art.

4 shows the "normal" attitude of the hand on a computer mouse 24 According to the state of the art. With the computer mouse 24 a movement is converted into an electrical signal sequence. It is therefore with a cable 25 connected to a processing device (not shown) such as a computer. The mouse is placed on a pad 26 emotional.

As can be seen, the links of the second to fifth fingers are significantly more elongated than is the case with the hand held in place 2 or in 3A to D, so that the angles β, γ, δ between the axes 19c . 19d and 19e are very small (and therefore in 4 not shown): the axes 19c . 19d and 19e run almost collinear. This means that the hand is overstretched and needs to expend a lot more force when making a movement in one of the directions 3A to 3C are shown to cause, as in the operation of a switching element of the device 24 is required.

In the case of the computer mouse according to the invention, by contrast, the mouse is operated from the functional position of the hand, since the functional position is the most suitable position for the daily work of the hand. In the functional position, the flexor and extensor muscles are in balance. This means that the fingers of the MP, PIP and DIP joints are bent so that the hand takes an incomplete fit as in 3A to 3C is shown.

Generally become in the mouse according to the invention front one or more buttons from the end member of the second and third or another finger operated. The printing direction of the keys is in the sagittal axis, i. from the front to the back. The pressure is in the direction of the palmar surface (Inner surface the hand) exercised. Depending on the version The mouse moves the print operation to the longitudinal axis upon actuation of the incomplete Fist. Here are the push buttons (switching elements) then operated from bottom to top. The printing operation wanders forward - back over then rising from the front below - behind above to ultimately below - above.

In the following some embodiments of the mouse according to the invention will be described with reference to FIG 5 to 11 explained in detail.

5A shows an embodiment of the device with an anatomical-physiological shape (for right-handed) from the left side. The device comprises a grip device with a grip part 27 on a base part 28 with a support surface 29 , The hand rests on the handle 27 that has a thumbball recess 30 as well as a guide bed 31 for the base and end member of the thumb. There With the hand is comfortable and fatigue-free, so it is above the handle 27 slightly arched. The recess 30 for the ball of the thumb and the guide bed 31 prevent slipping of the hand. The switching elements 32 and 33 are arranged one above the other so that they can be easily reached by the end member of the thumb. So there is a switching element 32 at the end of the guide bed 31 below immediately above the base of the device. Another switching element 33 in the form of a wheel is located above the guide bed 31 in the handle part 27 integrated and is also easily accessible with the thumb end member.

5B shows the same device from above. In addition to those associated with 5A explained features of the device are in 5B also guide beds 36 for the middle member of the second, third, fourth and fifth fingers and a recess 37 visible to the little finger bale. These contribute to further improving the grip of the hand on the handle part 27 and thus prevent premature fatigue of the hand due to incorrect loads.

In the representation of the device from the front in 5C is another element as a guide bed 35 represented for the finger end members. This also prevents slipping of the fingertips and therefore gives the user more security in handling the computer mouse. In the guide bed 35 for the finger end members are next to each other two switching elements 32 integrated, which can be operated particularly well with the second and third fingers.

In 5D the device is shown from the back. On the back of the device is a palmar support 34 provided, resting on the middle hand, so that a slipping of the mouse is prevented under the user's hand. Right in the figure is again the small finger bale recess 37 shown, left in the figure are the two switching elements for the thumb 32 and 33 shown.

at another (not shown) preferred embodiment is a wheel or a roller arranged laterally inward so that it from the end member of the thumb comfortably from top to bottom or back turned to the front and vice versa or in one direction in between can be. The wheel is as a combined turning and pushing device intended. The wheel can also be used on all models instead of the printing device of the index finger, where it can be conveniently moved in the longitudinal axis.

In 6A to 6D a device according to the invention in the form of a "shell" is shown. Their basic shape is substantially symmetrical to the longitudinal direction of the hand, ie, the left and the right half are almost mirror-symmetrical to each other.

How out 6A the handle part is visible 27 bulge. At its rear end, it is slightly concave, giving a thumb-ball recess 30 with guide bed 31 for the thumb end member. In this thumbball recess 30 rest your thumb, and it will give the hand additional support. On the left side, easily accessible for the thumb, are two switching elements 32 arranged. Furthermore, in the viewable since Lich guide bed 35 for the finger end members at least one further switching element 32 intended.

From above is in 6B next to the thumb ball recess 30 with guide bed 31 for the thumb end member a small finger recess 37 visible, by which the contact pressure on the hand is reduced at this point and so fatigue is counteracted. There are also guide beds 36 intended for the finger middle links. They also give the hand additional support and relieve pressure on the middle links of the fingers.

In the representation of the device from the front in 6C are in addition to those already associated with 6A and 6B explained features two switching elements 32 in the depression 35 represented for the finger end members. As with the embodiment described above with reference to FIG 5 has been explained, here are the two front switching elements 32 good with the second and third fingers to reach.

Finally, the device is in the form of a "shell" in 6D shown from the back, with the recesses for the thumb ball recess 30 with guide bed 31 for the thumb end member and the thumbnails recess 37 emerge.

Due to the conch-like configuration of this embodiment, the gripping surface widens forward, while on the rear side a thumb ball recess is provided, and the surface has additional guide contours for the thumb end member and the remaining finger end members. This will ensure that the end members of the fingers 2 to 4 not be bent backwards, but only downwards.

In embodiment of the invention in the form of a "Manta" according to 7 come two different directions of pressure, such as once from bottom to top and the second operating switch from the bottom front to obliquely behind the top, on a mouse used. In addition, one or more pressure devices may be actuated from the thumb in the manner of the fistula grip towards the inner surface of the hand. Here, the actuation then takes place in the direction of the transverse axis. - The Transverse expansion of the handle part 27 transverse to the hand is therefore preferably chosen such that the middle hand 18 at the level of the finger base joint 14 of the second 3 , third 4 fourth 5 and fifth 6 Fingers takes a convex shape.

The device is in 7A shown from the front, with two switching elements 32 are arranged one above the other. Again, as in the embodiments already explained above, a thumb ball recess 30 with guide bed 31 intended. A third switching element 33 is located at the front so that it can be easily reached and operated with an end member of the second or third finger.

In the representation of the device from above in 7B are next to the guide beds 36 for the finger middle links also the thumb ball recess 30 with guide bed 31 , the thumbnails recess 37 and a center-hand support 34 shown. From this perspective, no switching elements are visible.

In the representation of the device from the front in 7C are the two switching elements 32 visible, which are attached to the side of the device. In addition, the other switching element 33 visible in front. This switching element 33 is a wheel that is easy to reach and manipulate with the end member of the second finger. In this illustration, it can be seen particularly well that the device in this embodiment is slightly beveled to the right, ie the surface falls off laterally to the outside of the hand. This ensures that the (right) hand comfortably on the handle part 27 is not forced into an unnatural lurch to the left, and also a slight twist of the hand is supported outwards. This feature also contributes to the fatigue-free handling of the device.

In 7D the device is shown from the back. In this perspective, the switching elements fall 32 with the thumb ball recess 30 with guide bed 31 together. On the back of the device is a center-hand support 34 , and on the right side of the device a small finger bale recess is provided.

In a further preferred embodiment according to 8A to 8D The mouse is designed for both right and left-handers. Seen from the left ( 8A ) has the device on both sides in the guide bed 35 for the finger end members two switching elements 32 only one of which can be seen in this illustration. Furthermore, the device also has on the side of another switching element 32 in the form of a pressure switch and another switching element 33 in the form of a wheel. Both switching elements 32 and 33 are arranged one above the other. These two latter switching elements are arranged in the embodiment shown only on one side of the device.

In the representation of the device from above in 8B the device appears essentially as a rectangle, with the switching element on one side 33 projects.

Accordingly, in the view from the front in 8C two switching elements 32 in the guide bed 35 recognizable for the finger end members as well as a switching element 33 and a switching element 32 one above the other on the right in the illustration. The two front switching elements 32 in the guide bed 35 are on the left side of the device, in the drawing on the right side.

The view of the device from behind in 8D is similar to the front view, except that it is laterally reversed. So there are two switching elements 32 in the guide bed 35 for the finger end members, but these are shown on the left in the illustration. Accordingly, the switching element 33 and the switching element 32 , which are both stacked, in 8D shown on the left side.

The embodiment for left and right handed people is of course mirror-symmetrical with respect to a vertical plane through the center of the device, apart from the laterally arranged switching elements 32 and 33 ,

In this embodiment, the handle device is virtually only the handle part 27 There is no socket part as in the previous embodiments.

A further development in spherical form is the embodiment according to 9A to 9D , Again, the grip device consists almost only from the handle part 27 , and there is no pedestal part. This is a particularly simple and thus on the one hand versatile and on the other hand inexpensive to produce form. In essence, the illustrated shape corresponds to a one-sided flattened ball.

Seen from the left is in 9A the handle part 27 with contact surface 29 shown, with one another on the side of a switching element 33 and a switching element 32 are located. Both switching elements 32 and 33 are operated with the thumb. At the front of the device is another switching element 32 which is operated accordingly by the second and third fingers.

Seen from above is in 9B only that switching element 33 to recognize at the side. This can be easily reached and operated by the end member of the thumb.

In the view of the device from the front in 9C are two switching elements 32 for the end members of the second and third fingers. They differ slightly in terms of their height above the support surface 29 the device. This ensures that they are optimally positioned in front of the finger tip of the second or the third finger and thus can be easily operated. In addition, in this illustration, the two side-mounted switching elements 32 and 33 shown.

In the view of the device from behind in 9D Finally, only the two laterally arranged switching elements 32 and 33 to see.

Thereby, that the handle body is designed ball-like, is a large-scale enclosure of the handle body through the hand possible.

Due to the functional position of the hand, the mouse according to the invention is preferably oriented transversely to the hand in the anatomical transverse axis. In particular, this is the case when the shape of the mouse corresponds to the shape of a handlebar or a climbing handle. An embodiment with such a shape is shown in FIG 10A to D shown.

In the view from the left it can be seen that a first switching element 32 and a second switching element 33 laterally in the handle body 27 are integrated. The handle body 27 is via an intermediate part with the base 28 connected with its bearing surface 29 on a base (not shown), the movement being in direction and speed by a sensor (not shown) provided in the base 28 is integrated, is converted into an electrical signal sequence. The two switching elements 32 and 33 on the side of the handle 27 are arranged are operated with the thumb. In addition, other switching elements 32 provided, which are operated with the end member of the second and third fingers.

As from the representation of the device from above in 10B it can be seen, runs the handle part 27 in the direction of the middle hand 18 perfectly straight; he is not bent. From this perspective, only the upper switching element 33 recognizable on the side.

Seen from the front, 10C , you realize that the two switching elements 32 are arranged slightly differently in height for the second and third fingers. This takes into account the different lengths of these two fingers. It can also be seen that in the horizontal of the handle part 27 completely straight. In short, the device in this embodiment is similar to a handlebar.

Accordingly, in the representation of the device from the rear in 10D only the two laterally arranged switching elements 32 and 33 visible, noticeable.

In this embodiment, in which the handle body 27 is formed like a handlebar and on a base (mandrel or base part) 28 seated, which rests on the surface, is especially for the thumb, the embrace more pleasant and easier.

Of the handle can in this embodiment in terms of a longitudinal center plane be formed symmetrically, so he for right and left operation suitable is.

To protect the fingertips when moving the device on a pad and / or to offer them a shelf, the handle has 27 in the embodiment according to 11 a beak 38 on, the front of the handle 27 is appropriate. Moreover, this embodiment is similar to the embodiment of the "ball", ie the handle part 27 lies directly with its bearing surface 29 on the (not shown) pad and has substantially the shape of a flattened ball on one side. The grip device is quasi turn only from the handle part 27 There is no pedestal part.

As from the representation of the device from the left in 11A can be seen, are two switching elements 32 . 33 laterally in the handle part 27 integrated. These two switching elements can be easily reached and operated by the thumb. Two more switching elements 32 are arranged in front for the second and third fingers. Of these two switching elements, only the leftmost is seen in this perspective.

From above, 11B , you can see the beak 28 serving as a pad for the fingers two to five. In addition, the upper of the two laterally arranged switching elements 33 to recognize.

From the front, 11C , are the two switching elements 32 visible for the second or third finger. These can be attached to the 32 designated positions may be arranged on the device; But they can just as well be arranged so that they contribute to a visually pleasing appearance of the device - in particular, so children can be addressed. In the illustration shown in 11C are therefore at the position that with 39 is designated, two graphical elements or two other switching elements provided.

In the representation of the embodiment from the rear, 11D , are the two laterally arranged switching elements 32 . 33 visible as well as the guide bed for the base and the end member of the thumb.

• 1. Vorteilhafterweise sind in dem hinterschnittenen Bereich des Griffteils Schaltelemente zur Mausbetätigung angeordnet, wobei bevorzugt eine Anordnung in sagittaler Richtung der Handinnenfläche vorgesehen ist, so dass die Betätigungsrichtung entsprechend zur Handinnenfläche weist. Die Schaltelemente können auch von unten nach oben betätigt werden, d.h. in kaudal-granialer Richtung. Dadurch wird die Ruhehaltung der Hand am wenigsten bei der Tastenbewegung gestört.
• 2. Der Grundkörper der Vorrichtung erstreckt sich vorzugsweise in der Beugeachse der Hand, während herkömmliche Mäuse einen länglichen Grundkörper senkrecht dazu, d.h. in Verlängerung der Hand, aufweisen.
• 3. Ein besonders anatomischer Griffkörper verläuft quer zur Hand, wobei die Rückseite der Handform entsprechend ausgebildet ist, d.h. es ist eine Daumenballenaussparung und eine Mittelhandstütze vorgesehen und eine Abflachung für den kleinen Fingerballen nach außen, d.h. in lateraler Richtung.
• 4. Es muss eine Auflagefläche vorhanden sein, die eine Gleitführung gegenüber der Tischoberfläche bildet. Der Körper wird also von oben mit der Hand umfasst und nach unten belastet. Generell verbreitert sich bei der anatomischen Maus der Querschnitt zu dem Daumen hin, während sich zu dem kleinen Finger hin der Umfang verrin gert. An der Vorderkante sind Führungsbetten für die Fingermittelglieder vorgesehen.

With regard to all the embodiments explained above, the following features can be summarized as particularly advantageous:

• 1. Advantageously, switching elements for mouse actuation are arranged in the undercut region of the grip part, whereby an arrangement in the sagittal direction of the palm of the hand is preferably provided so that the actuation direction is corresponding to the palm of the hand. The switching elements can also be operated from bottom to top, ie in caudal-granial direction. As a result, the rest position of the hand is the least disturbed in the key movement.
• 2. The main body of the device preferably extends in the flexion axis of the hand, while conventional mice have an elongated body perpendicular thereto, ie in extension of the hand.
• 3. A particularly anatomical handle body extends transversely to the hand, wherein the back of the hand shape is designed accordingly, ie there is a thumb ball recess and a middle-hand support provided and a flattening for the small finger ball outwards, ie in the lateral direction.
• 4. There must be a support surface that forms a sliding guide opposite the table surface. The body is thus covered from above with the hand and loaded down. Generally, in the anatomical mouse, the cross-section widens toward the thumb while the circumference diminishes toward the little finger. At the front edge guide beds are provided for the finger middle links.

It it should be understood that the embodiments of the invention described above are only to be understood as examples and that they are in different Hand sizes made can be e.g. also as mice for children, which are shaped according to the aforementioned ergonomic findings. So can the physiological burden of the mouse operation maximum be reduced.
