HANDHELD-GERÄT MIT VERBESSERTE BEDIENBARKEIT, FUNKTIONS- UND BETRIEBSSICHERHEIT  HANDHELD DEVICE WITH IMPROVED OPERABILITY, FUNCTIONAL AND OPERATIONAL SAFETY
Beschreibung description
Die Erfindung betrifft Handheld-Geräte, die aufgrund ihrer räumlichkörperlichen Ausgestaltung und Anordnung der Bedienelemente eine verbesserte Bedienbarkeit, Funktions- und Betriebssicherheit aufweisen. The invention relates to handheld devices that have improved operability, functional and operational safety due to their spatial configuration and arrangement of the controls.
Tragbare elektronische Anzeige- oder Bedienelemente, die bei Benutzung in der Hand gehalten und mit der Hand oder den Fingern bedient werden, sogenannte Handheld oder Handheld-Geräte sind bekannt. Darunter fallen tragbare Computer, sogenannte Electronic Organizer, PDAs, und Pocket Computer und sogenannte Tablet-Computer sowie Mobiltelefone mit erweiterten Funktionen, sogenannte Smartphones (früher„Communicator") und„Phablets" aber auch tragbare Spielkonsolen, tragbare Messgeräte oder andere Datenerfassungs- oder Anzeige- geräte sowie tragbare Geräte zum Abspielen von Musik oder Multimediainhalten und Navigationsgeräte, GPS-Empfänger. Portable electronic display or control elements held in the hand and operated by hand or fingers when in use are known as handheld or handheld devices. These include portable computers, so-called electronic organizers, PDAs, and pocket computers and so-called tablet computers and mobile phones with advanced features, so-called smartphones (formerly "Communicator") and "Phablets" but also portable game consoles, portable gauges or other data acquisition or display - devices and portable devices for playing music or multimedia content and navigation devices, GPS receivers.
Handheld-Geräte neuerer Bauart weisen insbesondere eine im Wesentlichen flache, plattenförmige oder tafelförmige Grundform mit bekanntermaßen streng rechteckigem Profil auf, welches zumindest zwei gegenüberliegende parallele gerade Kanten zeigt und lediglich die äußeren Ecken mit einem Verrundungsradius von wenigen Millimetern versehen sind. Gerade diese bisher allgemein angestrebte und weithin akzeptierte Bauform eines Handheld, sei es nun als Smartphone, Tablet-Computer, Navigationsgerät oder ähnliches, weist aber Nachteile bei der Bedienbarkeit und der Funktionssicherheit auf. All diesen Geräten ist nämlich gemeinsam, dass sie während des bestimmungsgemäßen Gebrauchs bei der Bedienung in der Hand gehalten werden, gleichzeitig aber gerade mit der Hand, die sie hält, bedient werden, um die gewünschte Funktionalität des Geräts zu erreichen. Bekanntermaßen erfolgt die Bedienung über berührungsempfindliche Felder, sogenannte Touchpads, oder berührungsempfindliche Anzeigeschirme, sogenannte Touchscreens. Zusätzlich oder alternativ weisen bekannte Handheld-Geräte gelegentlich auch andere Bedienelemente wie Drehräder oder Steuerknüppel auf. Bekannte Bedienoperationen sind das Eintippen von (alphanumerischen Zeichen und Befehlen über ein frontseitiges Tastenfeld oder aber vor allem sogenannte Zeige- und Wischbewegungen an einem berührungsempfindlichen Anzeigeschirm (Gestensteuerung). Hierbei bestehen aber insbesondere anatomisch bedingte Einschrän- kungen, welche die Bedienbarkeit zum einen oder aber vor allem den sicheren Halt des Geräts in der Hand während der Bedienung beeinträchtigen. Die technische Funktionssicherheit kann daher bei bestimmten Bedienoperationen nicht gewährleistet werden. Fehlbedienungen, versehentliche Programmstarts, die mit Ressourcenverbrauch einher- gehen, aber auch unmittelbar physische Schäden, weil sich das Gerät aus dem Handgriff löst und zu Boden fällt, sind häufig beobachtbar. Handheld devices of recent design have in particular a substantially flat, plate-shaped or tabular basic shape with a known strictly rectangular profile, which shows at least two opposite parallel straight edges and only the outer corners are provided with a rounding radius of a few millimeters. Especially this hitherto generally desired and widely accepted design of a handheld, be it as a smartphone, tablet computer, navigation device or the like, but has drawbacks in the usability and reliability. All these devices have in common that they are held during normal use in the operation in the hand, but at the same time just with the hand that holds them, be operated to achieve the desired functionality of the device. As is known, the operation takes place via touch-sensitive fields, so-called touchpads, or touch-sensitive display screens, so-called touchscreens. Additionally or alternatively, known handheld devices occasionally on other controls such as wheels or joysticks. Known operating operations are the typing of (alphanumeric characters and commands via a front-side keypad or, above all, so-called pointing and swiping movements on a touch-sensitive display screen (gesture control).) However, there are in particular anatomically-related restrictions, which are the operability on the one hand or before Therefore, the technical reliability can not be guaranteed in certain operating operations: incorrect operation, accidental program start-ups that involve the consumption of resources, but also direct physical damage, because the device is out of operation Handles and falls to the ground are often observable.
Der Erfindung liegt das technische Problem zugrunde, diese Nachteile zu überwinden und die Handhabbarkeit, Bedienbarkeit und Betriebssicherheit solcher Handheld-Geräte zu verbessern. Das technische Prob- lern wird gelöst durch ein Handheld-Gerät gemäß Hauptanspruch, insbesondere ein Handheld-Gerät mit tafelförmiger Grundform und frontseitigem Anzeigeschirm, welches erfindungsgemäß dadurch gekennzeichnet ist, dass zumindest zwei gegenüberliegende Seiten ein konve- xes und besonders kreisförmiges oder ellipsoides Profil aufweisen, so dass sich ein tonnenförmiges oder balliges Querschnittsprofil an der Tafelform ausbildet. The invention is based on the technical problem of overcoming these disadvantages and improving the manageability, operability and reliability of such handheld devices. The technical problem is solved by a handheld device according to the main claim, in particular a handheld device with a tabular basic shape and front-side display screen, which according to the invention is characterized in that at least two opposite sides are convex. xes and have a particularly circular or ellipsoidal profile, so that a barrel-shaped or spherical cross-sectional profile is formed on the sheet shape.
Unter einer platten- oder tafelförmigen Grundform wird hier vor allem eine im Wesentlichen vier- oder rechteckige und flache Platte oder Tafel verstanden, wie sie für gattungsgemäße Handheids üblich ist. Die Platte oder Tafel hat eine Hauptebene mit einem Seitenverhältnis, das sich vor allem an dem Seitenverhältnis des eingebauten fronseitigen Anzeigeschirm (Display) orientiert. Bevorzugt beträgt das Seitenver- hältnis von Breite zu Länge der Tafel etwa 4:3, 3:2, 14:9, 16:9, 1 ,85:1 , 2:1 oder 2,35:1. Die Dicke (Höhe) der Tafel beträgt bevorzugt etwa 1 % bis etwa 10% der Länge. Under a plate-shaped or tabular basic form is understood here especially a substantially four- or rectangular and flat plate or panel, as is customary for generic Handheids. The plate or tablet has a main plane with an aspect ratio that is primarily oriented to the aspect ratio of the built-in front-side display screen. Preferably, the aspect ratio of width to length of the panel is about 4: 3, 3: 2, 14: 9, 16: 9, 1, 85: 1, 2: 1 or 2.35: 1. The thickness (height) of the panel is preferably about 1% to about 10% of the length.
Unter einem konvexen Kantenprofil wird hier vor allem ein einer Kreisform oder einer Ellipse folgenden Kante verstanden. Die Dimensionie- rung ist in bevorzugten Ausgestaltungen wie folgt: Bildet die (ursprüngliche) gedachte gerade Kante der Tafel die Kreissehne, bildet die erfindungsgemäße Konvexe Kante den zugehörigen Kreisbogen. Dabei beträgt der Kreisradius etwa 2 bis 5 mal die Länge der Sehne und der Abstand der Sehne vom Kreismittelpunkt beträgt etwa 0,9 bis 0,95 des Kreisradius: Entsprechende Dimensionierungen gelten für ellipsoide Kantenformen. A convex edge profile is to be understood here in particular as an edge following a circular shape or an ellipse. In preferred embodiments, the dimensioning is as follows: If the (original) imaginary straight edge of the panel forms the circular chord, the convex edge according to the invention forms the associated circular arc. The circle radius is about 2 to 5 times the length of the chord and the distance of the chord from the circle center is about 0.9 to 0.95 of the circle radius: Corresponding dimensions apply to ellipsoidal edge shapes.
Gegenstand der Erfindung ist daher besonders ein als Smartphone ausgebildetes Handheld mit einer typischen Größe seines Anzeigeschirms von etwa 7 bis 12,5 cm (vgl. etwa 3 bis 5 Zoll) Schirmdiagona- le, das zur ßenutzgng in der Regel mit einer Hand gehalten und mit genau dieser auch bedient wird. Darunter werden auch mobile Navigationsgeräte verstanden. Weiterer Gegenstand der Erfindung ist beson- ders ein als Tablet-PC ausgebildetes Handheld mit einer typischen Größe seines Anzeigeschirms von etwa 20 bis 28 cm (vgl. etwa 8 bis 11 Zoll) Schirmdiagonale, das zur Benutzung in der Regel beidhändig gehalten und bedient werden muss. Weiterer Gegenstand der Erfin- dung ist besonders ein als so genanntes„Phablet" bekanntes Handheld mit einer typischen Größe seines Anzeigeschirms von etwa 13 bis 18 cm (vgl. etwa 5,2 bis 7 Zoll) Schirmdiagonale, das zur Benutzung in der Regel beidhändig gehalten und bedient werden muss, aber auch mit einer Hand gehalten und bedient werden kann, wobei hier der Vorteil der erfindungsgemäßen Formgestaltung in ganz besonderer Weise zum Tragen kommt und welche die Betriebs- und Funktionssicherheit gerade bei diesen Ausführungen erheblich verbessert. The subject of the invention is therefore, in particular, a handheld device embodied as a smartphone with a typical size of its display screen of approximately 7 to 12.5 cm (cf., approximately 3 to 5 inches) screen diagonal which, as a rule, is held with one hand and with exactly this is also served. This also includes mobile navigation devices. Another object of the invention is particularly That is, a handheld computer designed as a tablet PC with a typical size of its display screen of about 20 to 28 cm (cf about 8 to 11 inches) screen diagonal, which usually needs to be held and operated ambidextrous for use. A further subject of the invention is in particular a handheld known as a "phablet" with a typical size of its display screen of about 13 to 18 cm (compare about 5.2 to 7 inches) screen diagonal, which is usually held ambidextrous for use and must be operated, but can also be held and operated with one hand, in which case the advantage of the design of the invention in a very special way comes to fruition and which significantly improves the operational and reliability especially in these versions.
Die Erfinder fanden nämlich überraschend, dass ein Handheld-Gerät, besonders wenn es diese typische gattungsgemäße flache, tafelförmi- ge Grundform aufweist, durch diese besondere Formgestaltung sicherer in der Hand gehalten und dabei wesentlich besser bedient werden kann. Die konvexe Form ermöglicht einen rutschsicheren Griff und gestattet, dass die Finger der Hand einen größeren Bereich des frontseitigen Bedienfelds sicherer erreichen, was die Funktionssicherheit des Geräts verbessert und die Gefahr von Fehlbedienungen reduziert. The inventors found that, surprisingly, a hand-held device, especially if it has this typical generic flat, tabular basic shape, can be held more securely in the hand by this special shape design and can be operated much better. The convex shape provides a non-slip grip and allows the fingers of the hand to reach a larger area of the front panel more securely, which improves the functional safety of the device and reduces the risk of operating errors.
Vorteilhafterweise braucht ein Bedienfeld, das gattungsgemäß regelmäßig mit dem Anzeigefeld zusammenfällt, selbst nicht dieser tonnen- förmigen oder balligen Grundform folgen, sondern kann selbst weiterhin streng rechteckig mit geraden Kantenprofilen ausgebildet sein. Selbst- verständlich ist aber auch vorgesehen, nicht streng rechteckige Bedien- und/oder Anzeigefelder einzusetzen, die sich in die ballige, konvexe Ausbuchtung des Profils hinhemerstrecken. In einer bevorzugten Ausgestaltung ist aber vorgesehen, dass zumindest das frontseitige Bedien- und/oder Anzeigefeld des Handheids eine Form aufweist, die dem anatomisch möglichen und insbesondere sinnvollen Bewegungsumfang der Finger der haltenden Hand angepasst sind. Bevorzugt ist das nicht rechteckige Bedien- und/oder Anzeigefeld dann fächerförmig oder als Ringsektor ausgebildet. Advantageously, a control panel which generally coincides regularly with the display panel itself does not need to follow this barrel-shaped or crowned basic shape, but may itself continue to be formed in a strictly rectangular manner with straight edge profiles. Naturally, however, it is also envisaged not to use strictly rectangular control and / or display fields which extend into the convex, convex bulge of the profile. In a preferred embodiment, however, it is provided that at least the front-side control and / or display panel of the hand has a shape which is adapted to the anatomically possible and in particular meaningful range of motion of the fingers of the holding hand. Preferably, the non-rectangular control and / or display panel is then fan-shaped or formed as a ring sector.
Entsprechende Vorteile zeigt die erfindungsgemäße neuartige Strukturierung auch bei Handheld-Geräten in Form von sogenannten„Tab- lets", die einen großen, querformatigen Anzeigeschirm aufweisen und üblicherweise mit beiden Händen gehalten werden. Auch hier passt sich die konvexe kreisförmige oder ellipsenförmige Profilierung der stirnseitigen Kanten an die anatomischen Bedingungen der Hände an und erhöht sogar so signifikant die Betriebssicherheit. Corresponding advantages of the novel structuring according to the invention also show in handheld devices in the form of so-called "tablets", which have a large, oblong display screen and are usually held with both hands.Also, the convex circular or elliptical profiling of the frontal edges fits to the anatomical conditions of the hands and even significantly increases the reliability.
