Definitions
- the invention is directed to a telescopic arrangement for a children's toy, in particular a toy vehicle, such as excavators, shovels, trucks or the like, comprising at least one telescopic tube and a longitudinally displaceably arranged telescopic piston and connecting means at the free end of the telescopic tube on the one hand and the free end of the telescopic piston on the other.
- a toy vehicle in the form of a shovel with, such a telescopic arrangement is, for example DE 20 2005 001 824 U1 or DE 20001819 U . DE 20001738 U . DE 20301186 U known.
- the invention is based on the object, such a telescopic arrangement in such a way that it can be locked in a simple manner in at least two end positions, but preferably in any intermediate positions.
- the telescopic tube may have a radially outwardly extending actuating tab.
- the locking pin has at its free outer end a connecting part which engages over the telescopic tube end and determines in the longitudinal direction.
- the locking pin may be provided at its outer end with a locking projection for a ring collar of the telescopic tube, so that the entire assembly can be mounted by simply mating and locking.
- a toy excavator 1 with a chassis 2 and four wheels 3 is shown, wherein on the chassis 2, a housing 4 is pivotally mounted, from which an excavator 5 extends upward, comprising three hinged sections 6, 7, 8, wherein at the extreme end of section 8 an excavator bucket 8a is arranged.
- a telescopic arrangement 9 according to the invention, which in upright excavator arm 5, as in Fig. 1 shown, extended and with lowered excavator 5, as in Fig. 2 shown, retracted.
- telescopic assembly 9 comprises a telescopic tube 10, a telescopic piston 11 and a locking pin 12th
- a connecting part 13 is provided for connection to the portion 6 of the excavator arm 5, which also serves as an axial stop against an annular collar 14 on the telescopic tube 10.
- a locking projection 15 is further formed on both sides of the locking pin 12, so that the annular collar 14, the telescopic tube 10 which projects inwardly, can be slid over an inclined surface 16 of the locking projection 15 and axially fixed.
- the telescopic piston 11 has at its end also a connecting part 17 for establishing a connection with the section 7 of the excavator arm 5.
- the telescopic piston 11 is seen in cross-section as a half-shell, so that it can engage over the locking pin 12 in the interior of the telescopic tube 10.
- the locking pin 12 has, based on the illustration in Fig. 5 on its upper side a rack portion 18, which forms a plurality of ArretierausEnglishungen 19 and locking projections 20.
- a corresponding rack portion 21 is provided which also forms locking recesses 22 and locking projections 23 again.
- the braces sections 18 of the locking pin 12 and 21 of the telescopic piston 11 engage with each other.
- the inner diameter of the telescopic tube 10 is dimensioned so that a certain clearance remains with respect to the interlocking entirety of the telescopic piston 11 and locking pin 12, which allows the rack sections 18 and 21 by a radial displacement either, as in Fig.
- an actuating tab 24 is provided on the telescopic tube 10, which allows the telescopic tube 10 to pivot relative to the entirety of locking pin 12 and telescopic piston 11.
- a radially inwardly projecting inclined surface 25 is provided, which merges into a tangential section 26 which is closed by a stop 27.
- Fig. 12 to 15 the unlocked position is shown.
- this consists between the rack assembly 21 of the telescopic cylinder 11 and the rack assembly 18 of the locking pin 12 a radial clearance, ie, it is an axial relative movement possible.

Description
Die Erfindung richtet sich auf eine Teleskopanordnung für ein Kinderspielzeug, insbesondere ein Spielzeug-Fahrzeug, wie Bagger, Schaufellader, Lastkraftwagen oder dergleichen, umfassend wenigstens ein Teleskoprohr und einen darin längs verschiebbar angeordneten Teleskopkolben sowie Verbindungseinrichtungen an dem freien Ende des Teleskoprohrs einerseits und dem freien Ende des Teleskopkolbens andererseits. Ein Spielzeugfahrzeug in Form eines Schaufelbaggers mit, einer derartigen Teleskopanordnung ist beispielsweise aus
Hiervon ausgehend liegt der Erfindung die Aufgabe zu Grunde, eine solche Teleskopanordnung so auszugestalten, dass diese auf einfache Weise in wenigstens zwei Endlagen, vorzugsweise aber in beliebigen Zwischenstellungen arretierbar ist.On this basis, the invention is based on the object, such a telescopic arrangement in such a way that it can be locked in a simple manner in at least two end positions, but preferably in any intermediate positions.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass
- der Teleskopkolben halbschalenartig ausgebildet ist und im Inneren der Halbschale wenigstens eine Arretierausnehmung aufweist,
- ein Arretierbolzen mit wenigstens einem zu der Rastausnehmung korrespondierendem Rastvorsprung sich längs erstreckend im Inneren des Teleskoprohrs und des Teleskopkolbens vorgesehen ist,
- Teleskopkolben und Arretierbolzen ein geringes radiales Spiel gegenüber dem Teleskoprohr aufweisen,
- das Teleskoprohr relativ zum Teleskopkolben und Arretierbolzen verschwenkbar ist,
- der Arretierbolzen relativ zum Teleskoprohr axial festgelegt ist,
- an der Innenseite des Teleskoprohrs eine sich von dessen Wandung radial nach Innen verlaufende Arretier-Schrägfläche aufweist, welche beim Verschwenken des Teleskoprohrs den Arretierbolzen radial gegen den Teleskopkolben und damit den Arretiervorsprung in die Arretierausnehmung drückt.
- the telescopic piston is of a half-shell-like design and has at least one locking recess in the interior of the half-shell,
- a locking bolt is provided with at least one locking projection corresponding to the latching recess extending longitudinally inside the telescopic tube and the telescopic piston,
- Telescope piston and locking pin have a slight radial clearance relative to the telescopic tube,
- the telescopic tube is pivotable relative to the telescopic piston and locking pin,
- the locking pin is fixed axially relative to the telescopic tube,
- on the inside of the telescopic tube has a radially inwardly extending from the wall locking inclined surface which presses the locking pin radially against the telescopic piston and thus the locking projection in the locking recess during pivoting of the telescopic tube.
Durch die erfindungsgemäße Ausgestaltung wird ein wirklichkeitsnahes äußeres Erscheinungsbild erreicht sowie eine stabile Fixierung ermöglicht.Due to the inventive design, a realistic appearance is achieved as well as a stable fixation allows.
Zur Erzielung einer besonders einfachen Handhabung kann das Teleskoprohr eine sich radial nach außen erstreckende Betätigungslasche aufweisen.To achieve a particularly simple handling, the telescopic tube may have a radially outwardly extending actuating tab.
Um eine Fixierung in beliebigen Zwischenstellungen zu ermöglichen, kann vorgesehen sein, dass an dem Teleskopkolben und an dem Arretierbolzen zahnstangenartige Abschnitte ausgebildet sind, durch die eine Mehrzahl von Arretierausnehmungen und Arretiervorsprüngen gebildet wird.In order to enable a fixation in any intermediate positions, it may be provided that on the telescopic piston and on the locking pin rack-like portions are formed, through which a plurality of Arretierausnehmungen and locking projections is formed.
Der Arretierbolzen weist an seinem freien äußeren Ende ein Verbindungsteil auf, welches das Teleskoprohr endseitig übergreift und in Längsrichtung festlegt.The locking pin has at its free outer end a connecting part which engages over the telescopic tube end and determines in the longitudinal direction.
Der Arretierbolzen kann an seinem äußeren Ende mit einem Rastvorsprung für einen Ringkragen des Teleskoprohrs versehen sein, so dass die gesamte Anordnung durch einfaches Zusammenstecken und Verrasten montiert werden kann.The locking pin may be provided at its outer end with a locking projection for a ring collar of the telescopic tube, so that the entire assembly can be mounted by simply mating and locking.
