Description

Die Erfindung bezieht sich auf einen Ladearm eines Spielfahrzeugs mit einer schwenkbaren Ladeschaufel, der eine hochschwenkbare Hauptstange mit einem an ihrem vorderen Ende vorgesehenen ersten Ladeschaufel-Schwenklager und einem an ihrem hinteren Ende vorgesehenen ersten Fahrzeug-Schwenklager und einen Ladeschaufel-Schwenkmechanismus umfasst.The invention relates to a loading arm of a toy vehicle with a pivoting loading shovel, comprising a swing-up main rod with a front end provided at first loading blade pivot bearing and provided at its rear end of the first vehicle pivot bearing and a bucket pivoting mechanism.

Ein derartiger Ladearm ist beispielsweise aus der DE 298 00 336.8 bekannt. Der dort beschriebene Ladearm enthält ein Ladeschaufel-Schwenkgestänge mit einem Schwenkhebel. Der resultierende Aufbau des Ladeschaufel-Schwenkmechanismus benötigt relativ viel Platz.Such a loading arm is for example from the DE 298 00 336.8 known. The loading arm described therein includes a loading bucket pivot linkage with a pivot lever. The resulting construction of the bucket swing mechanism requires a relatively large amount of space.

Die Aufgabe der Erfindung besteht deshalb darin, einen Ladearm der eingangs bezeichneten Art so anzugeben, dass der Ladeschaufel-Schwenkmechanismus einen geringeren Platzbedarf hat.The object of the invention is therefore to provide a loading arm of the type described above so that the loading bucket pivot mechanism has a smaller footprint.

Diese Aufgabe wird gelöst durch die Merkmale des unabhängigen Schutzanspruchs 1. Der erfindungsgemäße Ladearm umfasst

  1. a) eine hochschwenkbare Hauptstange mit einem an ihrem vorderen Ende vorgesehenen ersten Ladeschaufel-Schwenklager und einem an ihrem hinteren Ende vorgesehenen ersten Fahrzeug-Schwenklager und
  2. b) einen Ladeschaufel-Schwenkmechanismus, wobei
  3. c) der Ladeschaufel-Schwenkmechanismus ein vorderes, ein mittleres und ein hinteres Schwenkgestänge sowie eine Haltestange mit einem zweiten Fahrzeug-Schwenklager umfasst,
  4. d) das vordere Schwenkgestänge ein zweites Ladeschaufel-Schwenklager aufweist,
  5. e) das mittlere Schwenkgestänge das vordere und das hintere Schwenkgestänge kettengliedartig verbindet, und
  6. f) das hintere Schwenkgestänge jeweils schwenkbar im vorderen Abschnitt der Hauptstange und am vom zweiten Fahrzeug-Schwenklager abgewandten Ende der Haltestange angelenkt ist.
This object is achieved by the features of the independent protection claim 1. The charging arm according to the invention comprises
  1. a) a swing-up main rod with a provided at its front end first loading blade pivot bearing and provided at its rear end first vehicle pivot bearing and
  2. b) a bucket swing mechanism, wherein
  3. c) the bucket pivoting mechanism comprises front, middle and rear pivot links and a support bar with a second vehicle pivot bearing,
  4. d) the front pivot linkage has a second loader blade pivot bearing,
  5. e) the central pivot linkage connects the front and the rear pivot linkage in a chain link, and
  6. f) the rear pivot linkage is pivotally articulated respectively in the front portion of the main rod and the end remote from the second vehicle pivot bearing end of the support rod.

Der Ladeschaufel-Schwenkmechanismus des erfindungsgemäßen Ladearms lässt sich mit sehr geringem Platzbedarf realisieren. So ist das mittlere Schwenkgestänge in Fahrzeuglängsrichtung vorzugsweise sehr kurz ausgebildet. Diese Abmessung ist im Wesentlichen nur durch den Platzbedarf für die beiden Verbindungs-Schwenklager zur Verbindung mit dem vorderen bzw. dem hinteren Schwenkgestänge bestimmt. Der kompakte Aufbau ist außerdem auch durch den relativ nahe am vorderen Ende der Hauptstange, insbesondere im vorderen Drittel, angeordneten Anlenkpunkt des hinteren Schwenkgestänges an der Hauptstange bedingt. Auf diese Weise kann der Ladeschaufel-Schwenkmechanismus auch bei einem Ladearm eingesetzt werden, der nur eine vergleichsweise kurze Hauptstange hat und sich deshalb nicht für die bekannten Hebel-basierten Schwenkmechanismen eignet. Der Hebel-Mechanismus benötigt mehr Platz.The loading bucket pivoting mechanism of the loading arm according to the invention can be realized with very little space. Thus, the central pivot linkage in the vehicle longitudinal direction is preferably designed to be very short. This dimension is determined essentially only by the space required for the two connecting pivot bearing for connection to the front and the rear pivot linkage. The compact design is also due to the relatively close to the front end of the main rod, in particular in the front third, arranged articulation point of the rear pivot linkage on the main rod conditional. In this way, the bucket pivot mechanism can also be used in a loading arm, which has only a relatively short main rod and therefore is not suitable for the known lever-based pivoting mechanisms. The lever mechanism needs more space.

Darüber hinaus vermittelt der Ladeschaufel-Schwenkmechanismus des erfindungsgemäßen Ladearms den Eindruck einer sehr wirklichkeitsgetreuen Nachbildung des Originals. Insbesondere kann der bei den bekannten Hebel-basierten Schwenkmechanismen meistens recht auffällige und im Original nicht vorhandene Betätigungsgriff bei dem erfindungsgemäßen Ladearm sehr unauffällig in den Ladeschaufel-Schwenkmechanismus integriert werden.In addition, the loading bucket pivot mechanism of the loading arm according to the invention gives the impression of a very realistic replica of the original. In particular, in the known lever-based pivoting mechanisms usually quite conspicuous and not present in the original operating handle in the loading arm according to the invention can be integrated very inconspicuously in the loading bucket pivoting mechanism.

In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass das vordere, das mittlere und das hintere Schwenkgestänge jeweils als Parallel-Doppel-Gestänge mit zwei parallel zur Fahrzeuglängsachse angeordneten Seitenwangen und mit mindestens einer Querverstrebung ausgeführt ist. Dies entspricht dem großen Vorbild.In a further embodiment of the invention, it is provided that the front, the middle and the rear pivot linkage is designed in each case as a parallel double linkage with two side cheeks arranged parallel to the vehicle longitudinal axis and with at least one cross brace. This corresponds to the big role model.

Vorzugsweise kann weiterhin an einer der Querverstrebungen des vorderen Schwenkgestänges eine Einrastlasche vorgesehen sein, die in einer Endlage des Ladeschaufel-Schwenkmechanismus an einer der Querverstrebungen des mittleren Schwenkgestänges einrastet. Dadurch wird die Ladeschaufel in dieser Endlage gesichert.Preferably, on one of the cross struts of the front pivot linkage, a latching tab may be provided which engages in an end position of the loading-blade pivoting mechanism on one of the cross braces of the central pivot linkage. As a result, the loading bucket is secured in this end position.

Bei einer weiteren Variante ist an den Seitenwangen des vorderen Schwenkgestänges jeweils eine Aufnahme vorgesehen ist, in die ein Schwenklager der Verbindung zwischen dem mittleren und hinteren Schwenkgestänge in einer Endlage des Ladeschaufel-Schwenkmechanismus eingreift. Auch dies dient der Lagesicherung. Außerdem ergibt sich so ein sehr kompakter Aufbau.In a further variant, in each case a receptacle is provided on the side cheeks of the front pivot linkage, in which engages a pivot bearing of the connection between the middle and rear pivot linkage in an end position of the loading blade pivot mechanism. This also serves to secure the position. In addition, this results in a very compact design.

Insbesondere ist weiterhin am vorderen Schwenkgestänge ein die Aufnahmen verbindender und als Querverstrebung ausgeführter Betätigungsgriff vorgesehen. So fügt er sich sehr gut in die Optik des übrigen Ladeschaufel-Schwenkmechanismus ein und fällt praktisch nicht auf. Aufgrund der mechanischen Querstabilisierung des vorderen Schwenkgestänges erfüllt er außerdem eine Doppelfunktion.In particular, a connecting the recordings and executed as a cross-tie operating handle is still provided on the front pivot linkage. So he fits very well into the appearance of the rest of the bucket-tilting mechanism and practically does not fall on. Due to the mechanical stabilization of the front pivot linkage, it also fulfills a dual function.

Möglich ist auch eine Ausgestaltung, bei der eine weitere Haltestange vorgesehen ist, die in ihrem vorderen Abschnitt mittels einer an der Unterseite der Hauptstange angeordneten Führungshülse geführt ist.Also possible is an embodiment in which a further support rod is provided which is guided in its front portion by means of a guide sleeve arranged on the underside of the main rod.

Insbesondere hat die weitere Haltestange einen Rastvorsprung und die Hauptstange an ihrer Unterseite eine Rastkante, so dass der Rastvorsprung zur Verriegelung der Hauptstange in der hochgeschwenkten Position lösbar an der Rastkante einrastet. Dadurch lässt sich die Hauptstange in dieser Position sichern.In particular, the further support rod has a latching projection and the main rod on its underside a latching edge, so that the latching projection for locking the main rod in the raised position releasably engages the latching edge. This will secure the main bar in this position.

In den Fig. 1 bis 9 wird ein Spielfahrzeug 1 mit einem Ladearm 2 und einer schwenkbaren Ladeschaufel 3 in verschiedenen Positionen des Ladearms 2 und der Ladeschaufel 3 dargestellt. Grundsätzlich kann anstelle der Ladeschaufel 3 auch ein anderes Element, wie beispielsweise ein Pflug oder eine Strohballen-Gabel, vorgesehen sein. Im Ausführungsbeispiel handelt es sich bei dem Spielfahrzeug 1 um einen Gelenkradlader. Dieser Anwendungsfall ist jedoch nicht einschränkend für den erfindungsgemäßen Ladearm 2 zu verstehen.In the Fig. 1 to 9 For example, a toy vehicle 1 with a loading arm 2 and a pivoting loading shovel 3 in different positions of the loading arm 2 and the loading shovel 3 is shown. In principle, instead of the loading shovel 3, another element, such as a plow or straw bale fork, may also be provided. In the exemplary embodiment, the toy vehicle 1 is a Gelenkradlader. However, this application is not intended to be limiting for the loading arm 2 according to the invention.

Der Ladearm 2 umfasst eine Hauptstange 4, die an ihrem vorderen Ende mittels eines Ladeschaufel-Schwenklagers 5 schwenkbar mit der Ladeschaufel 3 und an ihrem hinteren Ende mittels eines Fahrzeug-Schwenklagers 6 ebenfalls schwenkbar mit dem Rumpf des Spielfahrzeugs 1 verbunden ist. Oberhalb der Hauptstange 4 ist ein Ladeschaufel-Schwenkmechanismus 7 angeordnet, der ein vorderes, ein mittleres und ein hinteres Schwenkgestänge 8, 9 bzw. 10 sowie eine Haltestange 11 beinhaltet. Die drei Schwenkgestänge 8, 9 und 10 sind jeweils als Parallel-Doppel-Gestänge mit zwei parallel zur Fahrzeuglängsachse angeordneten Seitenwangen 12, 13 bzw. 14 und mit Querverstrebungen 15, 16 bzw. 17 ausgeführt.The loading arm 2 comprises a main rod 4, which is connected at its front end by means of a loading blade pivot bearing 5 pivotally connected to the loading shovel 3 and at its rear end by means of a vehicle pivot bearing 6 also pivotally connected to the fuselage of the toy vehicle 1. Above the main rod 4, a bucket swing mechanism 7 is arranged, which includes a front, a middle and a rear pivot linkage 8, 9 and 10 and a support rod 11. The three pivot rods 8, 9 and 10 are each designed as a parallel-double linkage with two parallel to the vehicle longitudinal axis arranged side cheeks 12, 13 and 14 and with cross braces 15, 16 and 17 respectively.

Das Schwenkgestänge 8 ist an seinem vorderen Ende mittels eines zweiten Ladeschaufel-Schwenklagers 18 mit der Ladeschaufel 3 schwenkbar verbunden. Das Ladeschaufel-Schwenklager 18 ist ebenso wie das Ladeschaufel-Schwenklager 5 und das Fahrzeug-Schwenklager 6 in den Längsschnitten der Fig. 2 bis 9 verdeckt und deshalb nur gestrichelt eingetragen. Die Seitenwangen 12 des Schwenkgestänges 8 enthalten jeweils eine Aufnahme 19, die durch eine oben angeformte halbbogenförmige Vorwölbung gebildet ist. Diese Vorwölbungen an den Seitenwangen 12 sind mittels eines Betätigungsgriffs 20 miteinander verbunden, der zugleich auch als Querverstrebung des Schwenkgestänges 8 wirkt.The pivot linkage 8 is pivotally connected at its front end by means of a second loading blade pivot bearing 18 with the loading shovel 3. The loader blade pivot bearing 18 as well as the loading blade pivot bearing 5 and the vehicle pivot bearing 6 in the longitudinal sections of Fig. 2 to 9 hidden and therefore only indicated by dashed lines. The side cheeks 12 of the pivot linkage 8 each contain a receptacle 19, which is formed by a top-formed semi-curved protrusion. These protrusions on the side walls 12 are connected to each other by means of an actuating handle 20, which also acts as a cross brace of the pivot linkage 8 at the same time.

Das mittlere Schwenkgestänge 9 verbindet das vordere und das hintere Schwenkgestänge 8 bzw. 10 kettengliedartig, also jeweils gegeneinander schwenkbar.The central pivot linkage 9 connects the front and the rear pivot linkage 8 and 10 in the manner of a chain link, ie in each case pivotable relative to one another.

Das Schwenkgestänge 10 ist im vorderen Drittel der Hauptstange 4 schwenkbar außen an zwei Seitenwänden der Hauptstange 4 angelenkt. Benachbart zur Schwenkverbindung mit dem mittleren Schwenkgestänge 9 enthält das Schwenkgestänge 10 eine weitere Anlenkstelle zur schwenkbaren Verbindung mit dem vorderen Ende der Haltestange 11. An ihrem anderen Ende ist die Haltestange 11 mittels eines Fahrzeug-Schwenklagers 21 schwenkbar mit dem Rumpf des Spielfahrzeugs 1 verbunden.The pivot linkage 10 is hinged in the front third of the main rod 4 pivotally outside on two side walls of the main rod 4. Adjacent to the pivotal connection with the central pivot link 9, the pivot link 10 includes another pivot point for pivotal connection with the front end of the support rod 11. At its other end, the support rod 11 is pivotally connected by means of a vehicle pivot bearing 21 to the fuselage of the toy vehicle 1.

Neben der oberhalb und weitgehend parallel zu der Hauptstange 4 verlaufenden Haltestange 11 ist eine weitere Haltestange 22 unterhalb der Hauptstange 4 angeordnet. Die Hauptstange 4 weist an ihrer Unterseite eine Führungshülse 23 auf, durch die die Haltestange 22 lose hindurch gesteckt ist, so dass sich eine bewegliche Führung der Haltestange 22 in ihrem vorderen Abschnitt ergibt. An ihrem hinteren Ende ist die Haltestange 22 mittels eines dritten Fahrzeug-Schwenklagers 24 mit dem Rumpf des Spielfahrzeugs 1 schwenkbar verbunden. An einer der Unterseite der Hauptstange 4 zugewandten Seite der Haltestange 22 ist ein Rastvorsprung 25 angeformt. Als Gegenstück ist an der Unterseite der Hauptstange 4 eine Rastkante 26 vorgesehen. Der Rastvorsprung 25 rastet bei hochgeschwenkter Position des Ladearms 2 lösbar hinter der Rastkante 26 ein und sichert somit diese Position des Ladearms 2 (siehe Detailansicht gemäß Fig. 9).In addition to the above and largely parallel to the main rod 4 extending support rod 11, a further support rod 22 is disposed below the main rod 4. The main rod 4 has on its underside a guide sleeve 23, through which the support rod 22 is loosely inserted therethrough, so that there is a movable guidance of the support rod 22 in its front portion. At its rear end, the support rod 22 is pivotally connected by means of a third vehicle pivot bearing 24 with the fuselage of the toy vehicle 1. At one of the bottom of the Main rod 4 facing side of the support rod 22, a locking projection 25 is formed. As a counterpart, a latching edge 26 is provided on the underside of the main rod 4. The latching projection 25 engages in the swung-up position of the loading arm 2 releasably behind the locking edge 26 and thus secures this position of the loading arm 2 (see detail view according to FIG Fig. 9 ).

Im Folgenden wird die Funktionsweise des Ladeschaufel-Schwenkmechanismus 7 beschrieben.The operation of the bucket swing mechanism 7 will be described below.

Die Haltestange 11 bewirkt ein Aufstellen oder Absenken des hinteren Schwenkgestänges 10 je nach Schwenkstellung des Ladearms 2. Das Schwenkgestänge 10 wird also bei gegebener Schwenkstellung des Ladearms 2 in einer festen Position gehalten, die insbesondere unabhängig von der aktuellen Schwenkstellung der Ladeschaufel 3 ist.The support rod 11 causes a raising or lowering of the rear pivot linkage 10 depending on the pivot position of the loading arm 2. The pivot linkage 10 is thus kept at a given pivot position of the loading arm 2 in a fixed position, which is in particular independent of the current pivot position of the bucket 3.

Zum Verschwenken der Ladeschaufel 3 sind dagegen die beiden anderen Schwenkgestänge 8 und 9 vorgesehen. Der Ladeschaufel-Schwenkmechanismus 7 ist diesbezüglich so ausgelegt, dass zwei stabile Schwenkendpositionen der Ladeschaufel 3 existieren, in die sich der Ladeschaufel-Schwenkmechanismus 7 nach einem durch das spielende Kind veranlassten Überschreiten eines Totpunkts jeweils selbsttätig weiterbewegt.For pivoting the loading blade 3, however, the other two pivot rods 8 and 9 are provided. The bucket swing mechanism 7 in this regard is designed so that there are two stable swing end positions of the bucket 3, in which the bucket swing mechanism 7 moves automatically after exceeding one dead point caused by the child playing.

Die erste Schwenkendposition zum Entleeren der Schaufel 3 ist in Fig. 6 und 7 dargestellt. In dieser Stellung befindet sich die Schwenkverbindung zwischen dem vorderen Schwenkgestänge 8 und dem mittleren Schwenkgestänge 9 in Richtung der Fahrzeuglängsachse betrachtet vor der - bei bei gegebener Schwenkstellung des Ladearms 2 ortstabilen - Schwenkverbindung zwischen dem mittleren Schwenkgestänge 9 und dem hinteren Schwenkgestänge 10.The first pivot end position for emptying the bucket 3 is in FIG Fig. 6 and 7 shown. In this position, the pivotal connection between the front pivot linkage 8 and the central pivot linkage 9 is viewed in the direction of the vehicle longitudinal axis in front of - at a given swivel position of the loading arm 2 locally stable - pivotal connection between the central pivot linkage 9 and the rear pivot linkage 10th

Mittels einer entsprechenden Betätigung am Betätigungsgriff 20 durch das spielende Kind kann die Ladeschaufel 3 in die andere Schwenkendposition überführt werden, die in den Fig. 4, 5, 8 und 9 wiedergegeben ist. Dabei befindet sich die Schwenkverbindung zwischen dem vorderen Schwenkgestänge 8 und dem mittleren Schwenkgestänge 9 in Richtung der Längsachse des Spielfahrzeugs 1 betrachtet hinter der Schwenkverbindung zwischen dem mittleren Schwenkgestänge 9 und dem hinteren Schwenkgestänge 10. In dieser Schwenkendposition greift die Schwenkverbindung zwischen dem mittleren und dem hinteren Schwenkgestänge 9 bzw. 10 in die Aufnahmen 19 ein. Außerdem rastet eine an einer der Querverstrebungen 15 vorgesehene Einrastlasche 27 an der Querverstrebung 16 ein, die die Seitenwangen 13 auf Höhe dieser Schwenkverbindung verbindet. In Fig. 9 ist die eingerastete Stellung gezeigt, in Fig. 5 dagegen eine Stellung kurz vor dem Einrasten. Die Einrastlasche 27 sichert diese Schwenkendposition der Ladeschaufel 3 zusätzlich. Dies ist insbesondere dann von Vorteil, wenn die Ladeschaufel 3 beladen ist.By means of a corresponding operation on the operating handle 20 by the child playing the loading bucket 3 can be converted into the other pivoting end position in the Fig. 4 . 5 . 8th and 9 is reproduced. In this case, the pivotal connection between the front pivot linkage 8 and the central pivot linkage 9 is viewed in the direction of the longitudinal axis of the toy vehicle 1 behind the pivotal connection between the central pivot linkage 9 and the rear pivot linkage 10. In this Schwenkendposition the pivotal connection between the middle and the rear pivot linkage engages 9 and 10 in the recordings 19 a. In addition, a provided on one of the cross braces 15 locking tab 27 engages the cross bar 16, which connects the side cheeks 13 at the height of this pivotal connection. In Fig. 9 is the locked position shown in Fig. 5 however, a position just before snapping. The latching tab 27 additionally secures this pivoting end position of the loading shovel 3. This is particularly advantageous when the loading bucket 3 is loaded.

Der Ladearm 2 und insbesondere auch die Haltestange 22 sind aus Kunststoff hergestellt. Dadurch resultiert eine vorteilhafte Eigenelastizität. Diese bedingt, dass sich die Haltestange 22 beim Hochschwenken des Ladearms 2 ein Stück nach unten zurückbiegt, wenn der Rastvorsprung 25 mit seiner abgeschrägten Flanke an der Rastkante 26 entlang bewegt wird. Nach dem kompletten Überschreiten der Rastkante 26 schnappt die Haltestange 22 federnd zurück und der Rastvorsprung 25 kommt hinter der Rastkante 26 zu liegen, wodurch die Positionssicherung erreicht wird. Aufgrund des verwendeten Kunststoffs kann die Positionssicherung also besonders einfach und effizient realisiert werden. Bei einer anderen Materialwahl, beispielsweise bei einem Metall-Material, wäre aufgrund der schlechteren Eigenelastizität dagegen ein aufwändigerer Sicherungsmechanismus erforderlich.The loading arm 2 and in particular also the support rod 22 are made of plastic. This results in a beneficial inherent elasticity. This requires that the support rod 22 bends back a little while pivoting the loading arm 2 down when the locking projection 25 is moved with its bevelled edge on the locking edge 26 along. After completely exceeding the locking edge 26, the holding rod 22 snaps back resiliently and the locking projection 25 comes to lie behind the locking edge 26, whereby the position assurance is achieved. Due to the plastic used, the position assurance can therefore be implemented particularly easily and efficiently. For a different choice of material, such as a metal material, would be due to the poorer inherent elasticity however, a more elaborate security mechanism is required.

Insgesamt hat der Ladeschaufel-Schwenkmechanismus 7 einen sehr kompakten Aufbau. Außerdem ist der so realisierte Ladearm 2 dem Vorbild des Original-Fahrzeugs sehr ähnlich und bietet dennoch eine kindgerechte Handhabung.Overall, the bucket pivoting mechanism 7 has a very compact construction. In addition, the charging arm 2 realized in this way is very similar to the model of the original vehicle and nevertheless offers child-friendly handling.
