Description

Die Erfindung betrifft einen Spielzeugkreisel mit den im Oberbegriff des Anspruches 1 angegebenen Merkmalen.The invention relates to a toy spinning top with the features specified in the preamble of claim 1.

Spielzeugkreisel weisen in der Regel einen Standfuß auf, in dem eine vertikale, feststehende Standachse mit ihrem unteren Ende gehalten ist. Die Verbindung zwi­schen dem Standfuß und der Standachse ist abzugsicher auszubilden, um zum einen zu verhindern, daß der Krei­sel auf dem relativ scharfkantigen Ende seiner Stand­achse betätigt wird und somit Beschädigungen an Fußbö­den oder Mobiliar verursacht werden. Zum anderen ginge von dem freiliegenden Standachsenende ein erhebliches Verletzungsrisiko für die mit einem derart beschädigten Kreisel hantierenden Kinder aus.Toy spinning tops generally have a base in which a vertical, fixed base axis is held with its lower end. The connection between the pedestal and the pedestal is to be designed to be deductible, on the one hand to prevent the gyroscope from being actuated on the relatively sharp-edged end of its pedestal and thus causing damage to floors or furniture. On the other hand, the exposed end of the standing axis would pose a considerable risk of injury to the children handling such a damaged spinning top.

Auf der feststehenden Standachse ist der eigentliche Kreiselkörper drehbar gelagert. Für eine einwandfreie Funktion des Kreisels muß diese Lagerung eine ausrei­chend exakte Vertikalhaltung der Kreiselrotationsachse und eine wirkungsvolle Abstützung des Kreiselkörpers gegen seine Gewichtskraft und die durch den Angriff des Drallstabes nach unten wirkende Antriebskraft gewährlei­sten. Dazu sind zwischen der Standachse und dem Kreisel­körper zwei Radial- und ein Axial-Gleitlager vorhanden. Ein erstes Radial-Gleitlager wird durch eine zentri­sche, buchsenartige Lageröffnung in den vorzugsweise aus einem spritz- oder gießbaren Kunststoff gefertigten Spitzenteil des KreiselkGrpers gebildet. Die Standachse durchgreift diese Lageröffnung vertikal nach oben. Das zweite Radial-Gleitlager wird durch eine weitere zentri­ sche, buchsenartige Lageröffnung in einem im Spitzen­teil befestigten, ebenfalls vorzugsweise aus einem spritz- oder gießbaren Kunststoff gefertigten Einsatz­teil gebildet. In diese Lageröffnung liegt das obere Ende der Standachse ein. Durch den vertikalen Abstand der beiden Radial-Gleitlager wird die Vertikalhaltung der Kreiselrotationsachse erzielt. Da zwischen der Standachse und dem Spitzen- bzw. Einsatzteil relativ geringe Querkräfte auftreten und die Standachse mit entsprechendem Spiel in den Lageröffnungen gehalten ist, sind die Gleitreibungskräfte in diesen Lagern ver­nachlässigbar klein.The actual gyroscope body is rotatably mounted on the fixed standing axis. In order for the gyro to function properly, this mounting must ensure that the gyro rotation axis is held in a sufficiently precise vertical position and that the gyro body is effectively supported against its weight and the driving force acting downwards through the action of the swirl rod. For this purpose, two radial and one axial plain bearing are available between the standing axis and the gyro body. A first radial slide bearing is formed by a central, bush-like bearing opening in the tip part of the rotary body, which is preferably made of an injection-moldable or pourable plastic. The standing axis extends vertically upwards through this bearing opening. The second radial plain bearing is centered by another cal, bush-like bearing opening in an attached in the tip part, also preferably made of an injection or castable plastic insert. The upper end of the standing axis lies in this bearing opening. The vertical spacing of the two radial plain bearings ensures that the gyro rotation axis is kept vertical. Since relatively small transverse forces occur between the standing axis and the tip or insert part and the standing axis is held in the bearing openings with corresponding play, the sliding friction forces in these bearings are negligibly small.

Anders ist dies bei dem Axial-Gleitlager, das insbeson­dere die hohe Antriebskraft des Drallstabes aufnehmen muß. Hier ist ein direkter Kontakt zwischen feststehen­den und rotierenden Kunststoff- bzw. Metall- und Kunst­stoffteilen unbedingt zu vermeiden, da in diesen Fällen eine hohe Gleitreibungskraft und ein außerordentlich hoher Verschleiß im Lager auftreten würde. ßefriedigen­de Lagereigenschaften werden durch die Verwendung von metallenen Lagerelementen zwischen feststehenden und rotierenden Lagerteilen erzielt. Entsprechend ist bei Spielzeugkreiseln nach dem Stande der Technik zwischen dem Spitzen- und dem Einsatzteil eine Anquetschung vor­gesehen, die als vertikales Gegenlager für zwei auf die Standachse von oben aufgefädelte Ringscheiben dient. Auf diesen Ringscheiben stützt sich das im Spitzenteil beispielsweise durch Ultraschallverschweißung oder Ver­klebung befestigte Einsatzteil ab, wodurch die axiale Lagerung gegeben ist. Die untere Ringscheibe kann be­dingt durch die Quetschung stillstehen, während die obere sich mit dem Einsatzteil und folglich dem Spitzen­teil drehen kann. Die Gleitlagerung findet also zwi­schen den beiden metallenen Ringscheiben statt und weist entsprechend einen geringen Gleitreibungswider stand und Verschleiß auf. Die besagte Anquetschung dient gleichzeitig als Abzugssicherung für den Kreisel­körper von der Standachse.This is different with the axial plain bearing, which in particular has to absorb the high driving force of the swirl rod. Direct contact between stationary and rotating plastic or metal and plastic parts must be avoided here, since in these cases a high sliding friction force and an extraordinarily high level of wear would occur in the bearing. ß satisfactory bearing properties are achieved through the use of metal bearing elements between fixed and rotating bearing parts. Correspondingly, in the case of toy spinning tops according to the prior art, a crimp is provided between the tip part and the insert part, which serves as a vertical counter bearing for two ring disks threaded onto the standing axis from above. The insert part fastened in the tip part, for example by ultrasound welding or gluing, is supported on these ring disks, as a result of which the axial bearing is provided. The lower ring disc can stand still due to the crushing, while the upper one can rotate with the insert part and consequently the tip part. The plain bearing therefore takes place between the two metal ring disks and accordingly has a low sliding friction resistance got up and wear. The said crimping also serves as a trigger protection for the gyro body from the standing axis.

Nachteilig bei dieser bekannten Konstruktion ist ihr außerordentlich hoher Montageaufwand. Die beiden Ring­scheiben müssen eigens auf die Standachse aufgefädelt werden. Insbesondere eine Montage des Kreisels auf Fer­tigungsautomaten ist wegen der schwierigen Handhabung der Ringscheiben nur schwer möglich.A disadvantage of this known construction is its extremely high installation effort. The two washers must be threaded onto the standing axis. In particular, assembly of the gyroscope on production machines is difficult because of the difficult handling of the washers.

Davon ausgehend liegt der Erfindung die Aufgabe zugrun­de, die Lagerkonstruktion des Kreiselkörpers an der Standachse hinsichtlich des Fertigungsaufwandes zu ver­einfachen und verbessern und insbesondere eine automa­tische Fertigung zu ermöglichen.Proceeding from this, the object of the invention is to simplify and improve the bearing construction of the gyro body on the standing axis with regard to the manufacturing effort and, in particular, to enable automatic production.

Die Lösung dieser Aufgabe ist in den kennzeichnenden Merkmalen des Anspruches 1 angegeben. Demnach wird die bisher regelmäßig beim Stand der Technik verfolgte Axiallagerung durch Anquetschungen an der Standachse und daraufsitzenden Lagerringscheiben vollkommen aufge­geben und durch eine Ausbildung der metallenen Lagerele­mente nach Art etwa einer Spitzenlagerung ersetzt. Das eine Lagerelement wird von der oberen Stirnfläche der Standachse selbst gebildet. Das andere Lagerelement ist durch eine auf dieser Stirnfläche angeordnete Lager­kugel realisiert, welche am geschlossenen Innenende der über das obere Ende der Standachse gestülpten, sackloch­artigen Lageröffnung des Einsatzteiles sitzt.The solution to this problem is specified in the characterizing features of claim 1. Accordingly, the axial bearing, which has been regularly pursued in the prior art, is completely abandoned by crushing on the standing axis and bearing ring washers sitting thereon and is replaced by a design of the metal bearing elements in the manner of, for example, a tip bearing. One bearing element is itself formed by the upper end face of the standing axis. The other bearing element is realized by a bearing ball arranged on this end face, which sits at the closed inner end of the blind hole-like bearing opening of the insert part which is slipped over the upper end of the standing axis.

Damit ergibt sich grundsätzlich bereits eine Verringe­rung der benötigten Anzahl von Lagerteilen um ein Teil.This basically results in a reduction of the required number of storage parts by one part.

Der so gestaltete Erfindungsgegenstand kann darüber hinaus auch problemlos von einem Fertigungsautomaten montiert werden, da lediglich die Kugel in die sackloch­artige Lageröffnung des vorgefertigten Einsatzteiles eingelegt, anschließend die Standachse eingeführt und die so geschaffene Anordnung in das Spitzenteil einge­setzt werden. In einem letzten Schritt kann der Stand­fuß auf das untere Ende der Standachse aufgeschoben wer­den. Ein weiterer Vorteil liegt in der gegenüber dem Stand der Technik verringerten Gleitreibung zwischen der Lagerkugel und der Standachse, da hier ein im we­sentlichen punktförmiger Metall-Metall-Kontakt vorhan­den ist.The subject matter of the invention designed in this way can also be easily assembled by a production machine, since only the ball is inserted into the blind hole-like bearing opening of the prefabricated insert, then the stand axis is inserted and the arrangement thus created is inserted into the tip part. In a final step, the stand can be pushed onto the lower end of the stand axis. Another advantage lies in the reduced sliding friction between the bearing ball and the standing axis compared to the prior art, since there is an essentially point-like metal-metal contact.

Eine vorteilhafte Weiterbildung des Erfindungsgegenstan des ist im Kennzeichen des Anspruches 2 angegeben. Durch die Halterung der Lagerkugel am geschlossenen Innenende der Lageröffnung ist die Montage des erfin­dungsgemäßen Spielzeugkreisels weiter vereinfacht. Das Einsatzteil mit bereits eingesetzter Lagerkugel kann als vorkonfektioniertes Teil zur Endmontage des Krei­sels bereitgestellt werden. Die Halterung der Lagerku­gel kann dabei durch Verklebung, Einschmelzen oder - wie im Kennzeichen des Anspruches 3 angegeben ist ­selbsthemmend unter Preßpassung erfolgen. Hierzu kann die Lagerkugel beispielsweise gleichzeitig mit dem Spritzen oder Gießen des Einsatzteiles in die Lageröff­nung eingebracht werden.An advantageous development of the subject of the invention is specified in the characterizing part of claim 2. By mounting the bearing ball at the closed inner end of the bearing opening, the assembly of the toy top according to the invention is further simplified. The insert part with the bearing ball already inserted can be provided as a pre-assembled part for final assembly of the gyro. The mounting of the bearing ball can be done by gluing, melting or - as indicated in the characterizing part of claim 3, it is self-locking with a press fit. For this purpose, the bearing ball can, for example, be introduced into the bearing opening simultaneously with the injection molding or pouring of the insert part.

Die in den Ansprüchen 4 und 5 angegebenen Merkmale bringen eine weitere Reduzierung der Gleitreibung im Axial-Lager und eine Erhöhung dessen Standzeit mit sich.The features specified in claims 4 and 5 bring a further reduction in sliding friction in the axial bearing and an increase in its service life.

Weitere Merkmale, Einzelheiten und Vorteile der Erfin­dung können der nachfolgenden Figurenbeschreibung ent­nommen werden, in der ein Ausführungsbeispiel anhand der beiliegenden Zeichnung näher erläutert ist. Die Zeichnung zeigt einen Vertikallängsschnitt durch das untere Lagerteil eines Spielzeugkreisels.Further features, details and advantages of the invention can be found in the following description of the figures, in which an exemplary embodiment is explained in more detail with reference to the accompanying drawing. The drawing shows a vertical longitudinal section through the lower bearing part of a toy spinning top.

Der Kreisel weist einen als flachkegelförmiges Kunst­stoff-Formteil ausgebildeten Standfuß (1) auf, in des­sen Spitze eine Einstecköffnung (2) für das untere Ende (3) der Standachse (4) angeformt ist. In dieser Ein­stecköffnung (2) ist die koaxial zur Rotationsachse (5) des eigentlichen (strichliert angedeuteten) Kreiselkör­pers (6) verlaufende Standachse (4) mittels des hutarti­gen Federringes (7) abzugsicher und rotationsfest gehal­ten. Die gezeigte Fußkonstruktion ist Gegenstand des europäischen Patentes Nr. 197092 (EP-Patentanmeldung 85 904 058.7).The gyroscope has a base (1) designed as a flat-conical plastic molded part, in the tip of which an insertion opening (2) for the lower end (3) of the base axis (4) is formed. In this insertion opening (2) the coaxial to the axis of rotation (5) of the actual (indicated by dashed lines) gyro body (6) standing axis (4) by means of the hat-like spring washer (7) is held trigger-proof and rotation-proof. The foot construction shown is the subject of European Patent No. 197092 (EP patent application 85 904 058.7).

Auf der Standachse (4) ist der Kreiselkörper (6) dreh­bar gelagert. Dazu weist dieser an seinem unteren Ende die mehrteilige Lagerkonstruktion (8) auf, die im we­sentlichen von dem dem Standfuß (1) zugewandten, etwa kegelstumpfförmigen Spitzenteil (9) und dem in dessen hohlen Innenraum (10) sitzenden Einsatzteil (11) gebil­det ist.The gyroscope body (6) is rotatably mounted on the standing axis (4). For this purpose, it has at its lower end the multi-part bearing structure (8) which is essentially formed by the approximately frustoconical tip part (9) facing the base (1) and the insert part (11) sitting in its hollow interior (10).

Die Standachse (4) durchgreift das aus einem spritzba­ren Kunststoff gefertigte Spitzenteil (9) vertikal nach oben über eine zentrische, buchsenartige Lageröffnung (12). Diese bildet ein erstes Radial-Gleitlager (13). Mit ihrem oberen Ende (23) liegt die Standachse (4) in einer zentrischen, buchsenartigen Lageröffnung (14) im Einsatzteil (11) ein, die nach Art eines Sackloches aus­gebildet ist und ein zweites Radial-Gleitlager (15) bil­det Zur axialen Gleitlagerung des Kreiselkörpers (6) auf der Standachse (4) ist am geschlossenen Innenende (16) der Lageröffnung (14) unter Preßpassung - also selbsthemmend - eine Lagerkugel (17) gehalten, die in einem punktförmigen Metall-Metall-Kontakt auf der obe­ren Stirnfläche (18) der Standachse (4) sitzt und somit ein Axial-Gleitlager (24) für den Kreiselkörper bildet.The standing axis (4) passes through the tip part (9) made of a sprayable plastic vertically upwards via a central, bush-like bearing opening (12). This forms a first radial slide bearing (13). With its upper end (23), the standing axis (4) lies in a central, bush-like bearing opening (14) in the insert part (11), which is designed in the manner of a blind hole and forms a second radial sliding bearing (15) for the axial sliding bearing Spinning top (6) A bearing ball (17) is held on the standing axis (4) at the closed inner end (16) of the bearing opening (14) with a press fit - that is to say self-locking - which is in a point-like metal-metal contact on the upper end face (18) of the standing axis ( 4) sits and thus forms an axial plain bearing (24) for the gyro body.

Das Einsatzteil (11) weist in seinem Mantelbereich eine ringförmige Schrägflanke (19) sowie einen an deren krei­selkörperseitigen Umfangsrand umlaufend angeordneten, radialen Ringvorsprung (20) auf. Durch Ultraschallver­schweißung in diesen Bereichen ist das Einsatzteil (11) dauerhaft mit dem Spitzenteil (9) verbunden. über das durch die Lagerkugel (17) und die Stirnfläche (18) der Standachse (4) gebildete Axial-Gleitlager (24) ist der Kreiselkörper (6) somit nach unten abgestützt. Eine besonders innige Verbindung zwischen dem Einsatz- (11) und dem Spitzenteil (9) wird durch die formschlüssige Anlage der Schrägflanke (19) und des Ringvorsprunges (20) an der Innenmantelfläche des Spitzenteiles (9) und dessen zum Ringvorsprung (20) komplementäre, umlaufende Ringschulter (21) erzielt.The insert part (11) has in its jacket area an annular oblique flank (19) and a radial annular projection (20) arranged circumferentially on its peripheral edge on the circumferential body side. The insert part (11) is permanently connected to the tip part (9) by ultrasonic welding in these areas. The gyro body (6) is thus supported downwards via the axial slide bearing (24) formed by the bearing ball (17) and the end face (18) of the standing axis (4). A particularly intimate connection between the insert part (11) and the tip part (9) is achieved by the positive engagement of the inclined flank (19) and the ring projection (20) on the inner lateral surface of the tip part (9) and its complementary to the ring projection (20), circumferential ring shoulder (21) achieved.

Zwischen dem Einsatz- (11) und dem Spitzenteil (9) ist an der Standachse (4) eine Anquetschung (22) ange­bracht, die das Spitzenteil (9) und somit den Kreisel­körper (6) vor einem Abziehen von der Standachse (4) schützt.Between the insert part (11) and the tip part (9) a crimp (22) is attached to the standing axis (4), which protects the tip part (9) and thus the gyroscope body (6) from being pulled off the standing axis (4) .
