Abstract

A braking device is provided to reduce the speed at which a shiftable spring motor runs down. The braking device includes a pallet which is mounted so that it can oscillate, the pallet having a pair or arms which cooperate with the teeth of an escape wheel 13 which rotates as the spring runs down. The pallet is connected to a pendulum weight. The depth of engagement of the arms of the pallet in the teeth of the escape wheel as well as the amplitude of oscillation of the pallet and/or the pendulum weight connected therewith allow the braking action to be changed and hence the speed at which the motor runs down in one of a plurality of selectable shift positions.

Description

Die Erfindung betrifft ein Federtriebwerk nach dem Oberbegriff von Anspruch 1. Funktionsweisen von Federtriebwerken sind grundsätzlich in den deutschen Patentschriften 2 019 085, 2 039 265, 21 05 734 und 21 66 490 und dessen be­sonders bevorzugter Aufbau in der deutschen Patentschrift 24 61 625 beschrieben, welche Erfindungen desselben Anmelders betreffen.The invention relates to a spring drive according to the preamble of claim 1. Functions of spring drives are described in principle in German Patents 2,019,085, 2,039,265, 2,055,734 and 2,166,490 and its particularly preferred structure in German Patent 24 61 625, which inventions of the same applicant concern.

Federtriebwerke dieser Art werden vorzugsweise wegen ihrer kompakten Bauweise in sehr kleinen Fahrspielzeugen verwen­det.Spring drives of this type are preferably used because of their compact design in very small driving toys.

Diese Federtriebwerke besitzen ein vergleichsweise einfach aufgebautes Differentialgetriebe, das vor allem optimal zum Antrieb schnellaufender Fahrspielzeuge geeignet ist.These spring drives have a comparatively simple differential gear, which is particularly ideal for driving high-speed toys.

Aus der deutschen Patentschrift 21 66 888 ist bereits der Vorschlag bekannt, bei einem Federtriebwerk der gattungsgemäßen Art zwischen Abtriebswelle des eigentlichen Feder­triebwerks und der Fahrzeugantriebswelle ein weiteres Unter­setzungsgetriebe anzuordnen, um mit diesem die Fahrgeschwin­ digkeit zu reduzieren.From German patent specification 21 66 888 the proposal is already known to arrange a further reduction gear in a spring drive of the generic type between the output shaft of the actual spring drive and the vehicle drive shaft in order to drive the speed with this reduce severity.

Diese Lösung ist zwar realisierbar, jedoch für preisgünstige kleine Fahrspielzeuge jedenfalls dann ungeeignet, ween dieses Getriebe außerdem noch schaltbar sein soll. Außerdem läßt sich dieses Untersetzungsgetriebe nicht ohne wesentliche Änderung in das Federtriebwerk nach der deutschen Patentschrift 24 61 625 integrieren.Although this solution can be implemented, it is in any case unsuitable for inexpensive small driving toys, since this transmission should also be switchable. In addition, this reduction gear can not be integrated into the spring drive according to the German patent specification 24 61 625 without a significant change.

In der deutschen Patentschrift DE-C-832 563 ist ein Federtriebwerk für Fahrspielzeuge mit den Merlemalen des Oberbegriffs von Anspruch 1 offenbart, das einen mechanischen Kraftspeicher in Form einer Spiralfeder aufweist, welcher über ein Ablaufgetriebe mit einer Antriebswelle getrieblich koppelbar ist. Das Federtriebwerk weist eine zuschaltbare Hemmeinrichtung mit einem auf einer Achse des Getriebes sitzenden Ankerrad auf, in das ein Schwinghebelelement eingreift. Zur Veränderung der Bremswirkung ist der Schwinghebel mittels eines Schiebers und einer Druckfeder durch Rasten für verschiedene Lagen einstellbar.In the German patent DE-C-832 563, a spring drive for toys with the merlem of the preamble of claim 1 is disclosed, which has a mechanical energy store in the form of a coil spring, which can be coupled to a drive shaft via a sequence gear. The spring drive has a switchable inhibiting device with an escape wheel seated on an axis of the transmission, in which a rocker arm element engages. To change the braking effect, the rocker arm can be adjusted for different positions by means of a slide and a compression spring.

Mit dieser Anordnung läßt sich zwar eine Veränderung der Ablaufgeschwindigkeit des Federtriebwerkes erreichen, allerdings nur innerhalb relativ enger Grenzen. Darüber hinaus ist die Verstellung der Ablaufgeschwindigkeit nur bedingt reproduzierbar.With this arrangement, a change in the running speed of the spring engine can be achieved, but only within relatively narrow limits. In addition, the adjustment of the running speed is only partially reproducible.

Die Aufgabe der Erfindung besteht demnach darin, ein gattungsgemäßes Federtriebwerk so zu verbessern, daß mit einfachen Mitteln eine Verstellung der Ablaufgeschwindigkeit in weiten Grenzen in reproduzierbarer Weise ermöglicht wird.The object of the invention is therefore to improve a generic spring drive so that a simple adjustment of the running speed is made possible in a reproducible manner.

Bei einem Untersetzungsgetriebe der eingangs genannten Art wird diese Aufgabe gemäß dem kennzeichnenden Teil von Anspruch 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen gekennzeichnet.In a reduction gear of the type mentioned, this object is achieved according to the characterizing part of claim 1. Advantageous developments of the invention are characterized in the dependent claims.

Bei einem erfindungsgemäßen Untersetzungsgetriebe ist zur Verstellung der an sich bekannten Hemmeinrichtung in Form eines pendelnd gelagerten Ankers, dessen Zähne jeweils abwechseln mit einem von zwei Armen in das Ankerrad hemmend eingreifen, ein in Schwingungsrichtung verschiebbarer Stellschieber vorgesehen, über den sich Eingriffstiefe und Schwingungsamplitude in weiten Grenzen reproduzierbar ver­stellen lassen. Hierzu sind am Anker in Schwingungsrichtung beidseitig versetzt angeordnete Anschläge vorgesehen, wel­chen Gegenanschläge zugeordnet sind. Hiermit lassen sich große Schaltstufen realisieren, die wie Gänge eines Schalt­getriebes für Kraftfahrzeugmotoren einstellbar sind.In a reduction gear according to the invention for adjusting the known inhibiting device in the form of an oscillating armature, the teeth of which alternately intervene with one of two arms to inhibitly engage the escape wheel, an adjusting slide which is displaceable in the direction of oscillation is provided, via which the depth of engagement and the oscillation amplitude vary within wide limits reproducibly adjusted. For this purpose, stops which are offset on both sides in the direction of vibration are provided on the armature, to which counter-stops are assigned. Large shift stages can be realized in this way, which are adjustable like gears of a manual transmission for motor vehicle engines.

Vorzugsweise sind die verschiedenen Schaltpositionen des Stellschiebers über eine mit der Bodenplatte zusammenwirken­de Rasteinrichtung vorgegeben.The various switching positions of the adjusting slide are preferably specified via a latching device which interacts with the base plate.

Für den Konstrukteur, der Fahrspielzeuge sehr unterschied­licher Abmessungen mit einem Federtriebwerk der erfindungs­gemäßen Art zu versehen hat, ist es vorteilhaft, wenn ohne wesentliche Änderungen die Eigenschaften des Federtriebwer­kes auf das Fahrspielzeug abgestimmt werden können.For the designer who has to provide driving toys of very different dimensions with a spring drive of the type according to the invention, it is advantageous if the properties of the spring drive can be matched to the driving toy without significant changes.

In vorteilhafter Weiterbildung der Erfindung wird dies dadurch ermöglicht, daß der pendelnd gelagerte Anker eine zusätzliche Pendelmasse aufweist, welche vorzugsweise lös­und austauschbar am Pendel befestigt ist. Durch Austausch der in Fahrtrichtung des Fahrspielzeuges hin- und her­schwingenden Pendelmasse kann die Fahrtrichtung des frei laufenden, also nicht schienengebundenen, Fahrzeuges be­einflußt werden, was z.B. dann notwendig ist, wenn die Fahrtrichtung in unerwünschter Weise vom Geradeauslauf abweicht.In an advantageous development of the invention, this is made possible in that the pendulum-mounted armature has an additional pendulum mass, which is preferably attached to the pendulum in a detachable and exchangeable manner. By exchanging the pendulum mass oscillating back and forth in the direction of travel of the toy, the direction of travel of the free-running, that is to say not rail-bound, vehicle can be influenced, which is necessary, for example, if the direction of travel is undesirably from straight running deviates.

Weitere vorteilhafte Ausgestaltungen der Erfindung sind nachstehend anhand eines Ausführungsbeispiels im einzelnen unter Bezugnahme auf die Zeichnungen erläutert.Further advantageous embodiments of the invention are explained below using an exemplary embodiment with reference to the drawings.

Der grundsätzliche Aufbau des Federtriebwerkes, dessen Ar­beitsweise in den eingangs zitierten Patentschriften im De­tail beschrieben ist, ist folgender:The basic structure of the spring drive, the operation of which is described in detail in the patents cited at the beginning, is as follows:

In einem geschlossenen Federhaus 10 befindet sich eine nicht dargestellte Feder, deren Federenden einerseits mit dem Federhauszahnrad 11 und andererseits mit dem Federkern­zahnrad 12 verbunden sind.In a closed barrel 10 there is a spring, not shown, the spring ends of which are connected on the one hand to the barrel gear 11 and on the other hand to the spring core gear 12.

Die gegeneinander umlaufenden Zahnräder 11 und 12 sind über ein sogenanntes Umkehrritzel 19, welches die starr mitein­ander verbundenen Ritzel 19a und 19b besitzt, und auf der Radachse 18 sitzende Antriebsritzel 18a und 18b derart ge­trieblich miteinander verbunden, daß auf die Radachse 18 ein Drehmoment ausgeübt wird, welches der Differenz der von den Zahnrädern 11 und 12 abgegebenen Drehmomente ent­spricht. Die Anordnung der Zahnräder ist hierbei ferner derart, daß die im Federhaus 10 befindliche Feder in einer bestimmten Schaltposition durch Verdrehen der Radachse 18 in beiden Richtungen gleichzeitig vom inneren und äußeren Ende her gespannt wird.The gears 11 and 12 rotating around one another are connected to one another in terms of gears via a so-called reversing pinion 19, which has the rigidly connected pinions 19a and 19b, and drive pinions 18a and 18b seated on the wheel axle 18 such that a torque is exerted on the wheel axle 18, which corresponds to the difference between the torques emitted by the gear wheels 11 and 12. The arrangement of the gears is also such that the spring in the barrel 10 is tensioned in a certain switching position by rotating the wheel axis 18 in both directions simultaneously from the inner and outer ends.

Die Teile dieses aus den einleitend genannten Patentschrif­ten bekannten Federtriebwerkes sind zwischen Triebwerkspla­tinen 14 gelagert, welche über die Pfeiler 16 miteinander verbunden sind. Das komplette Triebwerk ist mittels des in Fahrtrichtung vorn befindlichen Pfeilers 16 (in Figur 1 rechts) verschwenkbar an der Bodenplatte 60 gelagert. Das Federhaus 10 mit seinen Zahnrädern 11 und 12 ist mittels seiner Achse 15 zwischen den Platinen 14 verdrehbar gela­gert.The parts of this spring drive mechanism known from the patent specifications mentioned at the outset are mounted between engine plates 14, which are connected to one another via the pillars 16. The entire engine is pivotally mounted on the base plate 60 by means of the pillar 16 located at the front in the direction of travel (on the right in FIG. 1). The barrel 10 with its gears 11 and 12 is rotatably mounted between the plates 14 by means of its axis 15.

Mit der erfindungsgemäßen Vorrichtung wird der Ablauf des Federtriebwerkes verlangsamt, wobei der Grad der Verlangsa­mung veränderbar ist.With the device according to the invention, the running of the spring drive is slowed down, the degree of deceleration being changeable.

Diesem Zweck dient das erfindungsgemäße Hemmwerk, das aus einem mit dem Federhauszahnrad 11 fest verbundenen Ankerrad 13 und einem mit diesem zusammenwirkenden Anker 20 (vgl. Figur 3 und 4) besteht, der seinerseits über das Teil 33, das Pendel 30 mit der Pendelmasse 31 verbunden ist.This purpose is served by the escapement according to the invention, which consists of an anchor wheel 13 which is fixedly connected to the barrel gear 11 and an anchor 20 which interacts with it (see FIGS. 3 and 4), which in turn connects the pendulum 30 to the pendulum mass 31 via part 33 is.

Das Pendel 30 ist mittels der Pendelachse 32 zwischen den Armen 52 einer Pendelgabel 50 pendelnd gelagert. Die Pen­delgabel 50 selbst ist mit Verankerungsarmen 53 mit der Bo­denplatte 60 fest verbunden. Sie ist jedoch mittels des Steuerbolzens 51 dank ihrer Elastizität senkrecht zur Bo­denplatte begrenzt auslenkbar. Diesem Zweck dient der Stellschieber 40, der mittels des Stellhebels 41 längs der Bodenplatte 60 verschiebbar angeordnet ist. Er umgreift mittels einer Steuerkurve 46, deren genauere Ausbildung in den Figuren 5 bis 9 dargestellt ist, den Steuerbolzen 51 der Pendelgabel 50. Der Verlauf der Steuerkurve 46 bewirkt, daß die Pendelgabel 52 und damit die Pendelachse 32 bei Verschieben des Stellschiebers 40 aus der Position gemäß Figur 5 über diejenigen gemäß Figur 6, 7 in diejenige gemäß Figur 8 und 9 angehoben wird, wodurch der Anker 20 mit sei­nen Ankerarmen 21, 24 zunehmend stärker mit der Verzahnung des Ankerrades 13 in Eingriff gebracht wird, wie mit den Figuren 5a bis 9a im einzelnen veranschaulicht ist.The pendulum 30 is pivotally mounted between the arms 52 of a pendulum fork 50 by means of the pendulum axis 32. The pendulum fork 50 itself is firmly connected to the base plate 60 with anchoring arms 53. However, thanks to its elasticity, it can be deflected to a limited extent perpendicular to the base plate by means of the control bolt 51. This is the purpose of the adjusting slide 40, which is arranged to be displaceable along the base plate 60 by means of the adjusting lever 41. It encompasses the control pin 51 of the pendulum fork 50 by means of a control cam 46, the more precise design of which is shown in FIGS. 5 to 9. The course of the control curve 46 causes the pendulum fork 52 and thus the pendulum axis 32 when the adjusting slide 40 is displaced from the position 5 over those according to FIGS. 6, 7 into those according to FIGS. 8 and 9, whereby the armature 20 with its armature arms 21, 24 is increasingly engaged with the toothing of the armature wheel 13, as with FIGS. 5a to 9a is illustrated in detail.

Aus den Figuren 3 und 4 ist erkennbar, daß der untere Be­reich des Ankers 20 und des Pendels 30 sowie das Verbin­dungsteil 33 zwischen diesen in einer Wanne 61 gelagert sind, deren in Fahrtrichtung vorn und hinten gelegene Rän­der 66 über die Oberfläche der Bodenplatte 60 hochgezogen sind.It can be seen from FIGS. 3 and 4 that the lower region of the armature 20 and the pendulum 30 and the connecting part 33 between them are mounted in a trough 61, the edges 66 of which are at the front and rear in the direction of travel are pulled up over the surface of the base plate 60 .

Diese Wannenränder 66 dienen vor allem dazu, die Pendelbe­wegung des Ankers 20 insb. in seiner obersten Position zu begrenzen, um Verklemmungen zwischen den Ankerarmen 21 und 24 einerseits und dem Ankerrad 13 zu verhindern, was zu einer vollständigen Blockierung des Federtriebwerkes oder zumindest einer ungleichmäßigen Beeinflussung des Federtriebwerkablaufes führen könnte.These tub edges 66 serve primarily to limit the pendulum movement of the armature 20, in particular in its uppermost position, in order to prevent jamming between the armature arms 21 and 24 on the one hand and the armature wheel 13, which leads to a complete blocking of the spring drive or at least an uneven influence of the spring engine drain could result.

Die genaue Funktionsweise der erfindungsgemäßen Hemmein­richtung ist mit den nachfolgenden Figuren 5 bis 9 veran­schaulicht.The exact functioning of the inhibiting device according to the invention is illustrated in the following FIGS. 5 to 9.

Figur 5 zeigt die Hemmeinrichtung in der ersten Schaltpo­sition, in welcher der Stellschieber 40 mit einer Rastnase 42 in eine erste Raste 62 der Bodenplatte 60 eingreift. Zur weiteren Sicherung dieser Position liegt die auf der rechten Seite des Stellschiebers befindliche Anschlagflä­che 45 an einem Nocken 65 der Bodenplatte an.FIG. 5 shows the inhibiting device in the first switching position, in which the adjusting slide 40 engages with a latch 42 in a first catch 62 of the base plate 60. To further secure this position, the abutment surface 45 located on the right-hand side of the adjusting slide bears against a cam 65 of the base plate.

Die Oberseite des Stellschiebers 40 ist mit einer Anzahl von Anschlägen 43a bis 43f ausgestattet, mit welchen die Schwingungsamplitude der Pendelmasse 31 begrenzt wird. Zu diesem Zweck ist unterhalb der Pendelmasse 31 ein An­schlagsteil mit Anschlägen 34a, b, c sowie 35a vorgesehen, welche auf der Unterseite des Pendelteiles 34 angebracht sind, damit also mit der Pendelmasse 31 verbunden sind und welche mit den oben erwähnten Anschlägen 43a bis f in den verschiedenen Schalt- und Schwingpositionen zusammenwir­ken.The top of the slide valve 40 is equipped with a number of stops 43a to 43f, with which the oscillation amplitude of the pendulum mass 31 is limited. For this purpose, a stop part with stops 34a, b, c and 35a is provided below the pendulum mass 31, which are attached to the underside of the pendulum part 34, so that they are connected to the pendulum mass 31 and which with the abovementioned stops 43a to f in the different switching and vibration positions work together.

Bei der Schaltposition gemäß Figur 5 liegt die Pendelmasse 31 mit dem Teil 34 auf den Anschlägen 43d, 43e und 43g der­art auf, daß eine Pendelbewegung nicht möglich ist. Außer­dem ist der Anker 20, wie vor allem Figur 5a erkennen läßt, so weit nach unten abgesenkt, daß er mit dem bei Federab­lauf in Pfeilrichtung umlaufenden Ankerrad 13 nicht in Ein­griff gelangen kann.5, the pendulum mass 31 rests with the part 34 on the stops 43d, 43e and 43g in such a way that a pendulum movement is not possible. In addition, the armature 20, as can be seen above all in FIG. 5a, is lowered so far down that it cannot come into engagement with the armature wheel 13 rotating in the direction of the arrow when the spring expires.

Anker 20, Pendel 30 und Pendelmasse 31 sind hierbei so be­messen und gelagert, daß der Anker 20 gegenüber der Hori­zontallage leicht im Gegenuhrzeigersinn verschwenkt ist, so daß bei der Anordnung des Ausführungsbeispieles sicherge­stellt ist, daß die Zähne des Ankerrades 13 nicht mit den Armen 21 und 24 des Ankers 20 in Berührung kommen. Anker 20 mit Pendel 30 werden in dieser Position gehalten, da die Pendelgabel 50, in welcher die Pendelachse 32 gelagert ist, mittels des rechten Teiles der Steuerkurve 46 und des in diesem befindlichen Steuerbolzens 51 in der untersten Posi­tion gehalten wird.Armature 20, pendulum 30 and pendulum mass 31 are dimensioned and mounted so that the armature 20 is pivoted slightly counterclockwise relative to the horizontal position, so that it is ensured in the arrangement of the embodiment that the teeth of the escape wheel 13 are not with the arms 21 and 24 of the armature 20 come into contact. Armature 20 with pendulum 30 are held in this position, since the pendulum fork 50, in which the pendulum axis 32 is mounted, is held in the lowest position by means of the right part of the control cam 46 and the control bolt 51 located therein.

Mit den Figuren 6 und 6a ist die Hemmeinrichtung in der zweiten Schaltposition dargestellt.FIGS. 6 and 6a show the inhibiting device in the second switching position.

Um diese Schaltposition zu erreichen, ist der Stellschieber 40 aus der in Fig. 5 gezeigten Position nach rechts zu ver­schieben, bis seine Rastnase 42 in die zweite Raste 63 und seine Raste 44b in den Nocken 65 eingreifen. Durch diese Verschiebung wird die Pendelgabel 50, die mit ihrem Steuer­bolzen 51 in die Steuerkurve 46 eingreift, aus der unteren Position in die mittlere Position angehoben. In dieser mittleren Position kommt, wie Figur 6a deutlicher erkennen läßt, der Anker 20 mit dem Ankerrad 13 in Eingriff. Bei Um­lauf des Ankerrades 13 im Uhrzeigersinn läuft eines seiner Zähne auf die Innenseite des Ankerarmes 21 auf und ver­schwenkt diesen und hiermit das Pendel 30 mit der Pendel­masse 31 in die in den Figuren 7 und 7a gezeigte Position.In order to achieve this switching position, the adjusting slide 40 is to be shifted from the position shown in FIG. 5 to the right until its catch 42 engages in the second catch 63 and its catch 44b in the cam 65. As a result of this displacement, the pendulum fork 50, which engages with the control bolt 51 in the control cam 46, is raised from the lower position to the middle position. In this 6a, the armature 20 comes into engagement with the armature wheel 13. When the armature wheel 13 rotates clockwise, one of its teeth runs onto the inside of the armature arm 21 and pivots it and thus the pendulum 30 with the pendulum mass 31 into the position shown in FIGS. 7 and 7a.

Wie die Figuren 6 und 7 erkennen lassen, ist die Schwingam­plitude des Pendels dadurch begrenzt, daß es einerseits mit dem Anschlag 35a an der Zunge 35 auf den Anschlag 43f des Stellschiebers 40 (vgl. Figur 6) und andererseits mit dem Anschlag 34a auf den Anschlag 43b des Stellschiebers 40 (vgl. Figur 7) aufläuft. In der in den Figuren 7 und 7a ge­zeigten Position läuft das Ankerrad 13 mit einem seiner Zähne 13a auf die in bezug auf den Anker 20 nach innen ab­fallende Auflauffläche 25 des Ankers 20 auf. Da die Spitze des Zahnes 13a auf die Auflauffläche 25 des Ankers 20 unter einem spitzen Winkel aufläuft, vermag das Ankerrad 13 den Anker 20 mit geringerer Kraft wegzuschwenken.As can be seen from FIGS. 6 and 7, the oscillation amplitude of the pendulum is limited by the fact that on the one hand it is connected with the stop 35a on the tongue 35 to the stop 43f of the slide valve 40 (see FIG. 6) and on the other hand with the stop 34a on the stop 43b of the slide valve 40 (see FIG. 7). In the position shown in FIGS. 7 and 7a, the armature wheel 13 runs with one of its teeth 13a onto the run-up surface 25 of the armature 20 which drops inwards with respect to the armature 20. Since the tip of the tooth 13a runs onto the run-up surface 25 of the armature 20 at an acute angle, the armature wheel 13 can pivot the armature 20 away with less force.

Die Endposition, in welcher die erfindungsgemäße Hemmein­richtung ihre maximale Hemmwirkung entfaltet, ist mit den Figuren 8 bis 9 gezeigt.The end position in which the inhibiting device according to the invention unfolds its maximum inhibiting effect is shown in FIGS. 8 to 9.

Um in diese Position zu gelangen, ist der Steuerschieber 40 ganz nach rechts zu verschieben, bis seine Rastnase 42 in die dritte Raste 64 und seine Raste 44a in den Nocken 65 eingreifen und damit den Schieber in der Endposition ver­riegeln.In order to get into this position, the control slide 40 has to be moved all the way to the right until its catch 42 engages in the third catch 64 and its catch 44a in the cam 65 and thus lock the slide in the end position.

Mittels der Steuerkurve 46 und dem mit dieser zusammenwir­kenden Steuerbolzen 51 wird in vorbeschriebener Weise das Pendel 30 mit Anker 20 und Pendelmasse 31 weiter angehoben, wodurch die Eingriffstiefe der Ankerarme 21 und 24 in die Verzahnung des Ankerrades 13 auf ihr Maximum erhöht wird.By means of the control cam 46 and the control bolt 51 interacting therewith, the pendulum 30 with the armature 20 and the pendulum mass 31 is raised further in the manner described, whereby the engagement depth of the armature arms 21 and 24 in the toothing of the armature wheel 13 is increased to its maximum.

Gleichzeitig wird die Zuordnung der Anschläge am Stell­schieber 40 und Pendel 30 derart verändert, daß das Pendel 30 mit Pendelmasse 31 maximale Schwingweiten erreicht. So schlägt das Pendel 30 in seiner in Figur 8 rechten Position mit der stirnseitigen Anschlagfläche 35a an der Zunge 35 an den Anschlag 43e des Stellschiebers und in seiner linken Position gemäß Figur 9 mit seinem Anschlag 34b an den An­schlag 43a des Stellschiebers 40 an. Wie mit den strich­punktierten Symmetrielinien Z des Pendels deutlich gemacht, wird hierdurch die Schwingungsweite maximal vergrößert, was zwangsläufig zu einer Verlangsamung der Pendelbewegung und damit der Drehgeschwindigkeit des mit dem Federzahnrad 11 verbundenen Ankerrades 13 führt.At the same time, the assignment of the stops on the adjusting slide 40 and the pendulum 30 is changed in such a way that the pendulum 30 with the pendulum mass 31 reaches maximum vibration ranges. Thus, in its right position in FIG. 8, the pendulum 30 strikes the stop 35e on the tongue 35 with the end stop surface 35a on the tongue 35 and in its left position in accordance with FIG. 9 with the stop 43b on the stop 43a of the control slide 40. As made clear with the dash-dotted lines of symmetry Z of the pendulum, the range of vibration is hereby increased to a maximum, which inevitably leads to a slowdown of the pendulum movement and thus the rotational speed of the escape wheel 13 connected to the spring gear 11.

Um in dieser Position ein ungewolltes Blockieren des Anker­rades 13 zu vermeiden, ist der Ankerarm 21 mit einer vor­springenden Nase 23 versehen, welche in Zusammenwirken mit der Innenfläche des Ankerarmes 21 die Eingriffstiefe be­schränkt. Würde der Ankerarm 21 noch weiter in den Zahnzwi­schenraum eintauchen, könnte es zu einem totalen Stillstand des Ankerrades 13 oder zumindest zu einer ungleichmäßigen Hemmung und damit zu einem unrunden Ablauf des Federtrieb­werkes kommen.In order to avoid undesired blocking of the armature wheel 13 in this position, the armature arm 21 is provided with a projecting nose 23 which, in cooperation with the inner surface of the armature arm 21, limits the depth of engagement. If the armature arm 21 were to penetrate even further into the interdental space, the armature wheel 13 could come to a complete standstill or at least to an uneven inhibition and thus to a non-circular running of the spring drive.

In der gemäß Figur 9 dargestellten linken Schwingposition läuft anders als bei der Position gemäß Figur 7 und 7a der Zahn 13a des Ankerrades 13 auf die nach außen abfallende Fläche 26 des Ankerarmes 24, und zwar unter einem stumpfen Winkel, auf. Das hat zur Folge, daß in dieser Position die Reibung zwischen Anker 20 und Ankerrad 13 gegenüber der Reibung der Anordnung gemäß Figur 7a vergrößert ist, wo­durch eine weitere Vergrößerung der Hemmwirkung und damit Verlangsamung des Ablaufes erreicht wird.In the left oscillating position shown in FIG. 9, unlike in the position according to FIGS. 7 and 7a, the tooth 13a of the armature wheel 13 runs onto the outwardly sloping surface 26 of the armature arm 24, namely at an obtuse angle. The consequence of this is that in this position the friction between armature 20 and armature wheel 13 is increased compared to the friction of the arrangement according to FIG. 7a, which further increases the inhibiting effect and thus slows down the process.

Nach einem weiteren Vorschlag der Erfindung ist die vor­zugsweise aus Metall bestehende Schwingmasse 31 mit dem Pendel 30 lösbar verbunden. Damit besteht die Möglichkeit, die Hemmwirkung durch Austausch der Pendelmasse zu verän­dern, so daß das im übrigen unveränderte Federtriebwerk zum Antrieb unterschiedlich schwerer oder unterschiedlich ausgebildeter Spielzeugautos dienen kann. Dies ist für ei­ne rationelle Fertigung von großer Bedeutung.According to a further proposal of the invention, the oscillating mass 31, which is preferably made of metal, is detachably connected to the pendulum 30. This makes it possible to change the inhibitory effect by exchanging the pendulum mass, so that the spring mechanism, which is otherwise unchanged, can be used to drive toy cars of different weights or different designs. This is of great importance for efficient production.

Ebenso bedeutsam ist, daß die erfindungsgemäße Hemmein­richtung bei geringfügiger Änerdung des in der Fertigung befindlichen Federtriebwerkes z.B. nach dem deutschen Pa­tent 24 61 625 eingebaut werden kann. Bei diesem in der deutschen Patentschrift 24 61 625 beschriebenen und ge­zeigten Federtriebwerk brauchen lediglich die auf dem Fe­derzahnrad 1a befindlichen rein dekorativen Ansätze durch das Ankerrad 13 ersetzt und das Federtriebwerk nachträg­lich mit der erfindungsgemäßen Hemmeinrichtung, bestehend aus Anker 20, Pendel 30, Stellschieber 40 sowie Pendelga­bel 50, ergänzt zu werden, wobei nur geringfügige Änderun­gen an der Bodenplatte 60 notwendig sind.It is also important that the inhibiting device according to the invention can be installed, for example according to the German patent 24 61 625, with slight alteration of the spring engine being manufactured. In this spring drive described and shown in the German patent specification 24 61 625, only the purely decorative approaches located on the spring gear 1a need to be replaced by the escape wheel 13 and the spring drive subsequently with the inhibiting device according to the invention, consisting of anchor 20, pendulum 30, slide valve 40 and pendulum fork 50 to be supplemented, with only slight changes to the base plate 60 being necessary.

Damit läßt sich aber die Erfindung durch einfache und preisgünstige Maßnahmen an dem bekannten Federtriebwerk realisieren.However, this allows the invention to be implemented by simple and inexpensive measures on the known spring drive.

Eine vorteilhafte Nebenerscheinung der erfindungsgemäßen Hemmeinrichtung besteht darin, daß diese beim Ablauf des Federtriebwerkes ein Geräusch erzeugt, daß dem Motorenge­räusch ähnelt, wodurch die Attraktivität des Fahrspielzeu­ges für Kinder gesteigert wird.An advantageous side effect of the inhibiting device according to the invention is that it generates a noise when the spring drive runs off that resembles the engine noise, which increases the attractiveness of the toy vehicle for children.
