Description

Die Erfindung betrifft eine Spielzeug-Baugruppe mit einem Lastarm mit verstellbaren Lastarm-Anstellwinkel. Ferner betrifft die Erfindung ein Spielzeug mit einer derartigen Baugruppe.The invention relates to a toy assembly with a load arm with adjustable load arm angle of attack. Furthermore, the invention relates to a toy with such an assembly.

Eine derartige Spielzeug-Baugruppe und ein Spielzeug mit einer solchen Baugruppe sind aus der DE 93 02 435 U1 und der US 1,652,135 bekannt.Such a toy assembly and a toy with such an assembly are known from DE 93 02 435 U1 and the US 1,652,135 known.

Es ist eine Aufgabe der vorliegenden Erfindung, eine Spielzeug-Baugruppe der eingangs genannten Art derart weiterzubilden, dass deren Spieltauglichkeit verbessert ist.It is an object of the present invention to develop a toy assembly of the type mentioned in such a way that their playability is improved.

Diese Aufgabe ist erfindungsgemäß gelöst durch eine SpielzeugBaugruppe mit den im Anspruch 1 angegebenen Merkmalen.This object is achieved by a toy assembly with the features specified in claim 1.

Erfindungsgemäß wurde erkannt, dass eine Kulissenführung einer Betätigungseinrichtung zum Verstellen eines Lastarm-Anstellwinkels zur Möglichkeit führt, die Kraftentfaltung des Betätigungselements auf den Lastarm abhängig vom Anstellwinkel zu gestalten. Dies ermöglicht eine an den Spieleinsatz der Spielzeug-Baugruppe angepasste Krafteinleitung. Die Kraft über das Betätigungselement kann insbesondere bei Anstellwinkeln am stärksten eingeleitet werden, wo die stärkste Kraft zur Änderung des Anstellwinkels des Lastarms benötigt wird. Dies ist insbesondere dort der Fall, wo auf den Lastarm das höchste Drehmoment wirkt. Die Kulisse kann insbesondere so gestaltet werden, dass praktisch eine vom Anstellwinkel des Lastarms unabhängige Betätigungskraft auf das Betätigungselement resultiert. Die Anordnung der Kulisse kann derart sein, dass sich abhängig vom Lastarm-Anstellwinkel ein Abstand zwischen dem mindestens einen Führungselement der Spindelmutter und einer Schwenkachse, über die das Verbindungsende des Lastarms am Rahmen angelenkt ist, kontinuierlich und insbesondere progressiv verringert.According to the invention, it has been recognized that a slide guide of an actuating device for adjusting a load arm angle of attack leads to the possibility of designing the force development of the actuating element on the load arm depending on the angle of attack. This allows an adapted to the game use the toy assembly force application. The force on the actuator can be initiated most particularly at angles of attack where the strongest force is required to change the angle of attack of the load arm. This is especially the case where the highest torque acts on the load arm. The scenery can in particular be designed so that practically results in an independent of the pitch of the load arm operating force on the actuator. The arrangement of the backdrop may be such that, depending on the load arm angle of attack, a distance between the at least one Guide element of the spindle nut and a pivot axis, via which the connecting end of the load arm is articulated to the frame, continuously and in particular progressively reduced.

Die Spindelmutter kann genau zwei gegenüberliegende Führungselemente aufweisen, die mit zwei beabstandet parallel zueinander verlaufenden Teilkulissen der Kulisse zusammenwirken. Die Spindelmutter läuft dann zwischen diesen beiden Teilkulissen.The spindle nut may have exactly two opposing guide elements which cooperate with two spaced apart mutually parallel partial scenes of the backdrop. The spindle nut then runs between these two partial scenes.

Eine gekrümmte Ausführung der Kulisse nach Anspruch 2 erhöht den Gestaltungsspielraum und damit die Möglichkeiten der Gestaltung der Abhängigkeit einer Betätigungskraft vom Anstellwinkel des Lastarms. Eine Umdrehung der Spindel bei kleinen Anstellwinkeln kann dann in einem geringeren Hubwinkel resultieren als bei größeren Anstellwinkeln. Die Gestaltung der Kulisse, insbesondere die gekrümmte Gestaltung der Kulisse, kann so sein, dass bei Lastarm-Anstellwinkeln zwischen 0° (horizontal verlaufender Lastaram) und 40° die Hubkraft größer ist als oberhalb von 40°.A curved embodiment of the gate according to claim 2 increases the design freedom and thus the possibilities of designing the dependence of an actuating force on the angle of attack of the load arm. One revolution of the spindle at low angles of attack can then result in a smaller stroke angle than at larger angles of attack. The design of the scenery, in particular the curved design of the scenery, may be such that at load arm angles between 0 ° (horizontally extending Lastaram) and 40 °, the lifting force is greater than above 40 °.

Eine Ausgestaltung der Kulissenführung nach Anspruch 3 kann eine Beschädigung der Spielzeug-Baugruppe vermeiden helfen.An embodiment of the slotted guide according to claim 3 can help prevent damage to the toy assembly.

Anlaufschrägen nach Anspruch 4 erleichtern das Rückführen des mindestens einen Führungselements in die Kulisse.Run-on slopes according to claim 4 facilitate the return of the at least one guide element in the backdrop.

Bei einem teleskopierbaren Lastarm kommen die Vorteile der erfindungsgemäßen Kulissenführung besonders gut zum Tragen.In a telescopic load arm, the advantages of the slotted guide according to the invention come particularly well to fruition.

Die Vorteile eines Spielzeugs nach Anspruch 6 entsprechen denen, die vorstehend im Zusammenhang mit der Spielzeug-Baugruppe erläutert wurden.The advantages of a toy according to claim 6 are similar to those discussed above in the context of the toy assembly.

Dieses kämmt mit einer Zahnreihe 10, die längs einer Längsseite einer langlochartigen Durchtrittsöffnung 11 in der Lenkplatte 7 verläuft. Die Durchtrittsöffnung 11 stellt gleichzeitig ein Fenster zum Durchtritt des Lenk-Betätigungselements 5 durch die Lenkplatte 7 dar. Die Zahnreihe 10 verläuft nicht gerade, sondern folgt einer konvexen Krümmung einer Berandung der Durchtrittsöffnung 11. Die Durchtrittsöffnung 11 ist in einem Ausleger der Lenkplatte 7 ausgeführt, der sich auf Höhe des Lenk-Betätigungselements 5 von einem längs der Fahrtrichtung des Spielfahrzeugs 1 verlaufenden Haupt-Plattenabschnitt der Lenkplatte 7 aus erstreckt.At the height of the steering plate 7, the steering actuator 5 has an integrally molded gear 9. This meshes with a row of teeth 10 which extends along a longitudinal side of a slot-like passage opening 11 in the steering plate 7. The passage opening 11 simultaneously represents a window for the passage of the steering actuator 5 through the steering plate 7. The row of teeth 10 is not straight, but follows a convex curvature of a boundary of the passage opening 11.

Der in der Fig. 2 rechte Achsschenkel 12c kann aufgrund seines Höhenspiels sich relativ zum Fahrgestell 2 nach unten verlagern, sodass zwischen den Achsschenkel 12c und dem zugeordneten oberen Anschlag 15 des Fahrgestells 2 ein Abstand A resultiert. Auf diese Weise kann das dem Achsschenkel 12c zugeordnete Laufrad 3 den Kontakt mit dem unebenen Untergrund wahren. Das Höhenspiel der Achsschenkel 12 relativ zum Fahrgestell 2 wird nach unten begrenzt durch untere Fahrgestell-Anschläge 16 für die Achsschenkel 12. Fig. 2 shows the toy vehicle 1 with an impeller assembly for uneven and falling in the rear wheels of the toy vehicle 1 from left to right sloping terrain. The relative position of the stub axle 12d to the upper stop 15 has not changed. The Indian Fig. 2 right stub axle 12c can move due to its height clearance relative to the chassis 2 down, so that between the stub axle 12c and the associated upper stop 15 of the chassis 2, a distance A results. In this way, the associated with the stub axle 12 c Impeller 3 maintain contact with the uneven ground. The height clearance of the knuckle 12 relative to the chassis 2 is limited down by lower chassis stops 16 for the knuckle 12th

Das Spielfahrzeug 1 hat weiterhin eine Spielzeug-Baugruppe 17, zu der Details in den Fig. 6 bis 13 dargestellt sind. Die Spielzeug-Baugruppe 17 hat einen Lastarm 18, der in nicht dargestellter Weise teleskopisch ausfahrbar ist. Der Lastarm 18 hat ein nicht dargestelltes freies Ende zum Heben einer Last. Diesem freien Ende gegenüber liegt ein Verbindungsende 19 des Lastarms 18, über das dieser an einem Rahmen 20 der SpielzeugBaugruppe 17 montiert ist. Am Rahmen 20 ist das Fahrgestell 2 des Spielfahrzeugs 1 festgelegt.The toy vehicle 1 further has a toy assembly 17, to the details in the Fig. 6 to 13 are shown. The toy assembly 17 has a load arm 18 which is telescopically extendable in a manner not shown. The load arm 18 has an unillustrated free end for lifting a load. Opposite this free end is a connection end 19 of the load arm 18, via which it is mounted on a frame 20 of the toy assembly 17. On the frame 20, the chassis 2 of the toy vehicle 1 is fixed.

Eine Betätigungseinrichtung 21 dient zum Verstellen eines Lastarm-Anstellwinkels α und damit zum Anheben des freien Lastarm-Endes. Der Lastarm-Anstellwinkel α kann, wie aus der Sequenz der Fig. 6 bis 11 hervorgeht, zwischen einem minimalen Winkel von etwa 0° und einem maximalen Winkel von mehr als 50° kontinuierlich über die Betätigungseinrichtung 21 vorgegeben werden. Zur Verstellung des Lastarm-Anstellwinkels α ist der Lastarm 18 über ein Schwenkgelenk mit Schwenkachse S am Rahmen 20 angelenkt.An actuator 21 is used to adjust a load arm angle of attack α and thus to raise the free load arm end. The load arm angle α can, as from the sequence of Fig. 6 to 11 shows, between a minimum angle of about 0 ° and a maximum angle of more than 50 ° continuously via the actuator 21 are given. To adjust the load arm angle α of the load arm 18 is articulated via a pivot joint with pivot axis S on the frame 20.

Die Betätigungseinrichtung 21 hat eine am Rahmen 20 gelagerte Spindel 22, die mit einem Winkelvorgabe-Betätigungselement 23 in Form einer Kurbel zur Drehung um eine Spindelachse 24 in Antriebsverbindung steht. Zur Betätigungseinrichtung 21 gehört ferner eine Spindelmutter 25 mit zwei gegenüberliegend angeordneten Führungselementen 26 in Form von bolzenartigen Führungsansätzen. Die Betätigungseinrichtung 21 hat weiterhin eine lastarmfeste Kulisse 27, die mit den Führungselementen 26 der Spindelmutter 25 zur Kulissenfühning der Spindelmutter 25 relativ zum Lastarm 18 zusammenwirkt. Die Kulisse 27 ist gekrümmt ausgeführt.The actuating device 21 has a spindle 22 mounted on the frame 20, which is in drive connection with an angle setting actuating element 23 in the form of a crank for rotation about a spindle axis 24. The actuating device 21 further includes a spindle nut 25 with two oppositely arranged guide elements 26 in the form of bolt-like guide lugs. The actuator 21 further has a load arm fixed gate 27, with the guide elements 26 of the Spindle nut 25 to Kulissenfühning the spindle nut 25 cooperates relative to the load arm 18. The gate 27 is curved.

Diese Krümmung der Kulisse 27 ist derart, dass sich beim Aufstellen des Lastarms 18 der Abstand zwischen den Führungselementen 26 und der Schwenkachse S progressiv verringert. Bei gegebener Betätigungskraft, die am Winkelvorgabe-Bedienungselement 23 manuell ausgeübt wird, ist eine Hubkraft, die die Betätigungseinrichtung 21 auf den Lastarm 18 ausübt, bei kleinen Anstellwinkeln, insbesondere bei Anstellwinkeln im Bereich zwischen 0° und 40°, größer als bei größeren Anstellwinkeln, insbesondere bei Anstellwinkeln im Bereich zwischen 40° und 55°. Eine Umdrehung der Spindel 22 resultiert bei kleinen Anstellwinkeln in einer geringeren Hubwinkeländerung als bei größeren Anstellwinkeln.This curvature of the gate 27 is such that when setting up the load arm 18, the distance between the guide elements 26 and the pivot axis S is progressively reduced. For a given actuation force, which is exerted manually on the angle setting operating element 23, a lifting force exerted by the actuating device 21 on the load arm 18, at small angles of attack, in particular at angles of attack in the range between 0 ° and 40 °, greater than at larger angles of attack, especially at angles of attack in the range between 40 ° and 55 °. One revolution of the spindle 22 results in smaller angles of attack in a smaller Hubwinkeländerung than larger angles of attack.

Bei einer nicht dargestellten alternativen Gestaltung kann die Kulisse 27 auch geradlinig ausgeführt sein. Sichergestellt werden muss hierbei ein Verlauf der Kulisse, bei dem bei kleineren Anstellwinkeln ein größerer Abstand zwischen den Führungselementen 26 und der Schwenkachse S resultiert als bei größeren Anstellwinkeln. Bei der dargestellten Ausführung unterstützen sowohl ein grundsätzlicher, auch linear angenähert möglicher Verlauf der Kulisse 27 als auch die auf die Schwenkachse S zuführende Krümmung der Kulisse 27 die Abnahme der Hubkraft bei größeren Anstellwinkeln.In an alternative embodiment, not shown, the gate 27 can also be designed in a straight line. It must be ensured here a course of the scenery, in which at smaller angles of attack a greater distance between the guide elements 26 and the pivot axis S results than at larger angles of attack. In the illustrated embodiment support both a basic, even linearly approximate possible course of the gate 27 and the feeding on the pivot axis S curvature of the gate 27, the decrease in the lifting force at larger angles of attack.

Die Kulissenführung mit den Führungselementen 26 der Kulisse 27 ist so ausgestaltet, dass bei einer auf den Lastarm 18 wirkenden Überlast die Führungselemente 26 aus der Kulisse 27 ausrücken. Dies ist im Vergleich der Fig. 12 und 13 dargestellt. Fig. 12 zeigt die Spindelmutter 25 mit den in die Kulisse 27 eingerückten Führungselementen 26, also eine Stellung die derjenigen nach den Fig. 6 bis 11 entspricht. Fig. 13 zeigt die Spindelmutter 25 mit aus der Kulisse 27 ausgerückten Führungselementen 26.The slotted guide with the guide elements 26 of the guide 27 is designed so that when acting on the load arm 18 overload the guide elements 26 disengage from the gate 27. This is compared to the FIGS. 12 and 13 shown. Fig. 12 shows the spindle nut 25 with the engaged in the slot 27 guide elements 26, so a position the those after the Fig. 6 to 11 equivalent. Fig. 13 shows the spindle nut 25 with disengaged from the backdrop 27 guide elements 26th

Zur Erleichterung eines Einführens der Führungselemente 26 in die Kulisse 27 hat die Kulisse 27 Anlaufschrägen 28. Wenn beim Einführen der Führungselemente 26 in die Kulisse 27 über die Spindelmutter 25 und die Führungselemente 26 Druck auf die Anlaufschrägen 28 der Kulisse 27 ausgeübt wird, zwängen die Führungselemente 26 die Anlaufschrägen 28 und damit die beiden den jeweiligen Führungselementen 26 zugeordneten Teilkulissen der Kulisse 27 auseinander, bis die Führungselemente 26 in die Kulisse 27 einrücken können.To facilitate insertion of the guide elements 26 into the slot 27, the gate 27 has run-on slopes 28. When pressure is applied to the run-on slopes 28 of the slide 27 when inserting the guide elements 26 into the slot 27 via the spindle nut 25 and the guide elements 26, the guide elements force 26, the run-on slopes 28 and thus the two the respective guide elements 26 associated partial scenes of the gate 27 apart until the guide elements 26 can engage in the slot 27.

Das Spielfahrzeug 1 hat unter anderem folgende Spielfunktionen: Zum Lenken des Spielfahrzeugs 1 wird das Lenk-Betätigungselement intuitiv wie das Lenkrad eines Fahrzeugs betätigt. Bei einer Drehung des Lenk-Betätigungselements 5 nach rechts fährt das Spielfahrzeug 1 eine Rechtskurve und bei einer Betätigung nach links eine Linkskurve. Durch Betätigung des Winkelvorgabe-Betätigungselements 23 wird der Anstellwinkel des Lastarms 18 vorgegeben. Dort, wo die Last am freien Ende des Lastarms das höchste Drehmoment ausübt, nämlich im Bereich kleiner Anstellwinkel α, ist aufgrund der Gestaltung der Kulisse 27 die Hubkraft, die bei gegebener Betätigungskraft auf das Winkelvorgabe-Betätigungselement 23 ausgeübt werden kann, am größten. Hin zu größeren Anstellwinkeln α ist aufgrund des geringeren Drehmoments, das die Last ausübt, eine kleinere Hubkraft tolerierbar, sodass dann eine Umdrehung der Spindel 22 zu einer größeren Änderung des Anstellwinkels führt. Bei einer Überlast auf den Lastarm 18 rücken die Führungselemente 26, bevor Verbindungskomponenten beschädigt werden, aus der Kulisse 27 aus. Aufgrund der Anlaufschrägen 28 ist ein erleichtertes Rückführen der Führungselemente 26 in die Kulisse 27 zur Wiederherstellung der Kulissenführung gegeben. Weitere Betätigungselemente können zum Teleskopieren des Lastarms 18 sowie zum Betätigen einer gegebenenfalls am freien Ende des Lastarms 18 angeordneten Schaufel vorhanden sein.The toy vehicle 1 has, inter alia, the following game functions: For steering the toy vehicle 1, the steering actuator is operated intuitively as the steering wheel of a vehicle. Upon rotation of the steering actuator 5 to the right, the toy vehicle 1 travels a right turn and a left turn left. By actuating the angle input actuating element 23, the angle of attack of the load arm 18 is predetermined. Where the load at the free end of the load arm exerts the highest torque, namely in the range of small angle α, due to the design of the gate 27, the lifting force that can be exerted on the angle setting actuator 23 for a given operating force, the largest. Towards larger angles of attack α, a smaller lifting force is tolerable due to the lower torque exerted by the load, so that one rotation of the spindle 22 then leads to a greater change in the angle of attack. In the event of an overload on the load arm 18, the guide elements 26 move out of the slot 27 before connecting components are damaged. Due to the chamfers 28 is a facilitated return of the guide elements 26 in the backdrop 27 given to restore the slide guide. Further actuators may be provided for telescoping the load arm 18 and for actuating a blade optionally arranged at the free end of the load arm 18.

Das Spielfahrzeug 1 ist insgesamt aus Kunststoff ausgeführt. Die Komponenten des Spielfahrzeugs 1 sind Spritzgussteile.The toy vehicle 1 is made entirely of plastic. The components of the toy vehicle 1 are injection-molded parts.
