Description
Die Erfindung betrifft einen Trackball gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a trackball according to the preamble of claim 1.
Ein Trackball, wie aus den deutschen Gebrauchsmustern DE 91 15 189 U1 und DE 93 15 584 U1 bekannt, ist ein Peripheriegerät zur Steuerung der Bewegung des Cur sors. Dies erfolgt mittels eines kugelförmigen Gegenstandes, der als Trackball bezeichnet wird. Ein Trackball besitzt einen Durchmesser von etwa 1,5-2,0 cm und wird im allgemeinen in einem Personalcomputer eingesetzt, um die gleiche oder eine ähnliche Funktion auszuführen wie die herkömmliche Maus.A trackball, as from the German utility models DE 91 15 189 U1 and Known from DE 93 15 584 U1 is a peripheral device for controlling the movement of the cur sors. This is done using a spherical object called a trackball referred to as. A trackball has a diameter of about 1.5-2.0 cm and is generally used in a personal computer to do the same or perform a function similar to that of the conventional mouse.
Aus der US 5 029 292 wird eine Kugel beschrieben, die einen inneren Kern um faßt, der dieser Kugel das hauptsächliche Gewicht geben soll. Es wird jedoch als Nachteilig beschrieben, daß die Herstellung derartiger Kugeln schwierig ist, da dieser Kern genau mittig angeordnet sein soll, dies jedoch üblicherweise nicht er reicht wird. Daher wird eine kernlose Kugel aus einem einzigen Material mit ent sprechend Gewicht vorgeschlagen.From US 5 029 292 a ball is described which surrounds an inner core that should give this ball the main weight. However, it is considered Disadvantageously described that the production of such balls is difficult because this core should be arranged exactly in the middle, but usually not he is enough. Therefore, a coreless ball made of a single material is ent speaking weight suggested.
Ferner beschreibt die US 4 951 034 eine Kugel für eine Computermaus, welche ohne einem Kern aus Stahl oder einem anderen Metall in einem einzigen Arbeits gang mittels Spritzguß hergestellt wird.Furthermore, US 4 951 034 describes a ball for a computer mouse, which without a steel or other metal core in a single work gear is produced by injection molding.
Für Videospiele ist der Durchmesser des Trackballs im allgemeinen größer, bis etwa 10 cm. Es gibt zwei verschiedene Typen eines Trackballs für Videospiele, wobei einer einen hohlen Aufbau besitzt, während der andere massiv ausgebildet ist. Der hohle Trackball umfaßt zwei halbkugelförmige Schalen, die den Vorteil eines geringen Gewichts besitzen, während jedoch andererseits eine rauhe umlaufende Naht vorhanden ist, die durch die Kombination der beiden Schalen ent steht. Dementsprechend bevorzugt man die massive Ausführung des Trackballs, um das Auftreten der Verbindungsnaht zu vermeiden. Jedoch besitzt dieser her kömmliche massive Trackball den Nachteil, daß der gesamte massive Körper aus Acrylnitril-Butadien-Styrol (ABS) besteht, wobei dieser Werkstoff relativ schwer ist, kein wirkungsvolles Material darstellt und keinen leichtgängigen Betrieb zuläßt.For video games, the diameter of the trackball is generally larger, up to about 10 cm. There are two different types of video game trackballs, one having a hollow structure, while the other is solid is. The hollow trackball includes two hemispherical shells that have the advantage have a low weight, while on the other hand a rough circumferential Seam is present by the combination of the two shells ent stands. Accordingly, one prefers the massive execution of the trackball, to avoid the occurrence of the connection seam. However, this one comes from Conventional massive trackball has the disadvantage that the entire massive body is made up Acrylonitrile-butadiene-styrene (ABS), which material is relatively heavy, is not an effective material and does not allow smooth operation.
Der Erfindung liegt dementsprechend die Aufgabe zugrunde, einen Trackball zur Verfügung zu stellen, der unter Vermeidung der aufgezeigten Nachteile keine umlaufende Naht besitzt und andererseits sich durch ein geringes Gewicht aus zeichnet.The invention is accordingly based on the object of a trackball To provide the none while avoiding the disadvantages shown has all-round seam and on the other hand is characterized by a low weight draws.
Gelöst wird diese Aufgabe erfindungsgemäß durch einen Trackball der o. g. Art mit den in Anspruch 1 gekennzeichneten Merkmalen.This object is achieved according to the invention by a trackball from the above-mentioned. Kind with the features characterized in claim 1.
Hierzu ist es erfindungsgemäß vorgesehen, daß die Innenkugel aus einem Polyu rethanschaummaterial (PU) und die äußere Hohlkugel aus einem ungesättigten Polyester besteht, wobei die äußere Hohlkugel materialeinheitlich ausgebildet ist.For this purpose, it is provided according to the invention that the inner ball made of a polyu rethane foam material (PU) and the outer hollow sphere from an unsaturated Polyester is made, the outer hollow ball is made of the same material.
Dies hat den Vorteil, daß die Innenkugel leichter als die Außenkugel ist, wodurch sich verbesserte Bedieneigenschaften für einen Trackball ergeben, da das Ge wicht einerseits reduziert und andererseits hauptsächlich im Umfangsbereich des Trackballs konzentriert ist. Somit verbindet der erfindungsgemäße Trackball den Vorteil einer hohlen Kugel mit den Vorteilen einer Vollkugel ohne umlaufende Naht.This has the advantage that the inner ball is lighter than the outer ball, whereby improved operating properties for a trackball result because the Ge weight on the one hand and on the other hand mainly in the area of the Trackballs is focused. Thus, the trackball according to the invention connects the Advantage of a hollow ball with the advantages of a solid ball without a rotating one Seam.
Die Erfindung wird im folgenden anhand der Zeichnung näher erläutert. Diese zeigt in der einzigen Figur perspektivisch eine bevorzugte Ausführungsform des erfindungsgemäßen Trackballs.The invention is explained below with reference to the drawing. This shows in perspective in the single figure a preferred embodiment of the trackballs according to the invention.
Der dargestellte Trackball 12 umfaßt eine äußere Hohlkugel 10 sowie eine Innen kugel 11, die in die äußere Hohlkugel 10 paßt. Die Innenkugel 11 ist unbeweglich in der äußeren Hohlkugel 10 fixiert, die aus einem ungesättigten Polyester be steht. The trackball 12 shown comprises an outer hollow ball 10 and an inner ball 11 which fits into the outer hollow ball 10 . The inner ball 11 is immovably fixed in the outer hollow ball 10 , which is made of an unsaturated polyester.
Das eingesetzte Material ist ein Polymer in Form eines ungesättigten Polyesters. Die Innenkugel 11 besteht aus einem Polyurethan(PU)-schaummaterial, welches leichter ist als das herkömmlich eingesetzte Material.The material used is a polymer in the form of an unsaturated polyester. The inner ball 11 consists of a polyurethane (PU) foam material, which is lighter than the conventionally used material.
Somit vermeidet der Trackball 12 mit der Innenkugel 11 nicht nur die herkömmli che umlaufende Naht, da die äußere Kugel materialeinheitlich ausgebildet ist, sondern es wird auch das Gewicht erheblich vermindert, da die Innenkugel 11 aus Polyurethanschaum (PU) hergestellt ist.Thus, the trackball 12 with the inner ball 11 not only avoids the conventional circumferential seam, since the outer ball is made of the same material, but it also significantly reduces the weight, since the inner ball 11 is made of polyurethane foam (PU).
