Description

The invention relates to a toy vehicle according to the preamble of claim 1.

Such toy vehicles are known by public prior use. The DE 20 2010 001 555 U1 discloses a toy vehicle with a steerable chassis.

It is an object of the present invention, a toy vehicle of the type mentioned in such a way that a more diverse gaming experience is possible.

The object is achieved by a toy vehicle with the features specified in claim 1.

According to the invention, it has been recognized that a steering changeover device offers the possibility of predetermining different steering positions with corresponding steering relative positions of the steering plate sections which differ fundamentally from one another and which would not be possible by normal steering, that is to say by steering with the steering actuating device. The steering changeover device is actuated via a changeover actuating element, which is different from and independent of the actual steering confirmation device, which is usually designed as a steering wheel. The steering position of the steering changeover device can remain independent of the position of the steering actuating element. About the steering position of the steering changeover can be, for example, in addition to a normal straight-ahead driving position The wheels also bring about a driving position, which is known as crabbing. This driving position results in a straight ahead a rear axle offset from the front axle, so that each of the wheels drives in its own lane. This can be used for the underground gentle locomotion of the toy vehicle according to the real model. In the normal steering position in particular a cornering with two steered axles can be realized. Between the two steering positions of the steering changeover can be adjusted by switching the steering changeover a transitional steering position. For this purpose, the steering changeover between the two steering positions can be continuously or discretely be changed. In the two steering positions of the steering changeover device are basically different relative steering positions of the four wheels to each other or driving positions possible. The steering plate does not necessarily have to be plate-shaped, that is to say of low strength compared to the surface area. The steering plate or the individual steering plate sections can assume any spatial form that is suitable for the steering plate or the steering plate sections to fulfill their steering function.

A power transmission according to claim 2 can be realized robust.

This applies correspondingly to a design according to claim 3.

An arrangement of the steering actuator according to claim 4 allows intuitive steering. The steering actuator can be arranged as in the real example.

A position indicator according to claim 5 allows rapid control of the induced via the steering changeover steering position.

An arrangement according to claim 6 allows a kensing with a few components kinematic transmission via the steering changeover device. This can be accommodated in particular in the available space between the two vehicle axles of the toy vehicle.

A design of the changeover device according to claim 7 is robust executable.

A steering column Umstellgehäuse according to claim 8 makes it possible to specify according to the real model different positions of the steering column in order to control the vehicle in a movement in the corresponding direction of travel can.

A convertible steering column Umstellgehäuse is independent of the previously discussed steering changeover device and regardless of the other chassis design and in particular of the other steering design an independent feature of the invention.

A transmission toothed disk according to claim 9 allows a change of the steering column such that the position of components of the steering drive, apart from the steering column and the toothed pulley, can remain unchanged.

An embodiment of the steering drive unit according to claim 10 ensures that in the various positions of the steering column Umstellgehäuses the various steering components remain in operative connection with each other.

In the drawing, a chassis 1 of an otherwise not shown toy vehicle is shown, partly with omitted components and components. The toy vehicle may be a tractor or a substructure of a toy crane truck. The chassis 1 has a plurality, namely a total of four, of wheels 2, 3, 4 and 5. At one in the Fig. 1 shown on the left housing section 6 of a chassis housing 7, of which in the Fig. 1 only one half shown is, a trailer coupling, not shown, or device coupling is attachable. The in the Fig. 1 Left illustrated vehicle axle with the wheels 2 and 4 is hereinafter also referred to as trailer-side vehicle axle 8 and thereby of the in the Fig. 1 On the right vehicle axis 9 with the wheels 3 and 5 distinguished.

The two wheels 2 and 4 are mounted pivotably about a vertical axis on a trailer-side axle shaft 10 of the trailer-side vehicle axle 8. Hub-side, not co-rotating bearing body 11 (see. Fig. 16 ) of the wheels 2, 4 are also connected via a hinged between these wishbone 12 together. For steering the two trailer-side wheels 2, 4 is a steering plate portion 13 which is mounted on the chassis housing 7 pivotally about a pivot joint with a vertical pivot axis 14. A trailer-side end of the trailer side steering plate portion 13 has a slot 15 into which a fixedly connected to the trailer axle shaft 10 steering pin 16 engages. Opposite, the trailer side steering plate portion 13 has another slot 17 into which a hinge pin 18 of a middle steering plate portion 19 engages. The middle steering plate portion 19 is pivotable about a pivot joint with a vertical pivot axis 20.

A position of the pivot axis 20 transversely to the direction of travel can be set steplessly with a steering change-over device 21. The steering changeover device 21 has a laterally arranged changeover knob 22, which is accessible from the outside. Rotationally connected to the changeover knob 22 is a threaded spindle 23. The latter cooperates with a complementary thereto internal thread of a carriage body 24 which is guided transversely to the direction of travel displaceable on the chassis housing 7. The middle steering plate portion 19 is pivotable about the pivot axis 20 mounted on the carriage body 24. The steering changeover device 21 engages the middle steering plate portion 19.

The changeover knob 22 with the threaded spindle 23 is mounted axially and radially on the chassis housing 7.

On the opposite side of the hinge pin 18, the middle steering plate portion 19 has a serrated in an arcuate slot 25 tooth row 26. The latter meshes with a steering drive member in the form of a steering drive rod 27 via a longitudinally extending along a rod axis 28 toothing of a gear portion 29 of the steering drive rod 27. Der Gear section 29 represents an integrally formed on the steering drive rod 27 teeth.

The steering drive rod 27 is mounted axially and radially in a guide sleeve portion 30 of the chassis housing 7 (see. Fig. 16 ). Opposite to the bottom-side gear portion 29, the steering drive rod 27 has an upper, cab-side gear portion 31 with compared to the bottom gear portion 29 more than twice as large axial extent of a toothing 32nd

With this toothing 32 of the cab-side gear portion 31 of the steering drive rod 27 meshes a transmission toothed disc 33 which is mounted in a steering column Umstellgehäuse 34 about a vertically extending axis of rotation 35. On the opposite with respect to the axis of rotation 35 of the steering drive rod 27 side meshes with the transmission toothed disc 33, a gear portion 36 of a steering column 37 which is axially and radially mounted in the steering column Umstellgehäuse 34, and rotationally fixed to a toy vehicle steering wheel 38 is connected. A steering axle 38a closes to a chassis level, which is predetermined by the four wheels 2 to 5 and, for example, parallel to the plane of the Fig. 1 runs at an angle greater than 70 °.

Fixed to the carriage body 24 is a position indicator or steering position indicator of the steering-Umstelleinrichtung 21 serving pin 39, the one in the Fig. 1 not shown opening in the chassis housing 7 passes above the switching knob 22 for the user both visible and tactile.

Between the slot 25 for the passage of the steering drive rod 27 and the pivot axis 20 for the middle steering plate portion 19, a hinge pin with a vertical pivot axis 40 is arranged, via which the middle steering plate portion 19, another steering plate portion 41 for steering the two wheels 3, 5 hinged the other vehicle axle 9 is. The further steering plate portion 41 is pivotable on the chassis housing 7 about a pivot joint with housing-fixed vertical pivot axis 42. The further vehicle axle 9 faces, the steering for the two wheels 3, 5, the same steering components 10, 11, 12, 15, 16 as the steering for the two trailer-side wheels 2, 4, which bear the same reference numerals and not again in detail be explained.

The steering plate portions 13, 19 and 41 and the axle shafts 10, the bearing body 11 and the control arms 12 on the two vehicle axles 8, 9 are components of a steering device 42a of the chassis 1. The three steering plate sections 13, 19, 41 are components of an overall steering plate of Chassis 1. Axles 10 and wishbones 12 are steering elements of the steering device 42a. The steering drive rod 27 constitutes a steering drive element of the steering device 42a.

Fig. 1 shows the steering changeover device 21 in a first steering position with a first steering relative position of the steering plate sections 13, 19 and 41 to each other. In addition, the shows Fig. 1 a neutral driving position of the wheels 2 to 5 for a straight-ahead driving of the toy vehicle with the chassis 1. The position indicator pin 39 is at its free end is approximately at the level of a changeover knob 22 to the chassis housing 7 final bearing collar 43rd

Fig. 3 shows the chassis 1 with the steering change-over device 21 again in the first steering position. In the Fig. 3 is the steering wheel 38 to turn right (see direction arrow 44) taken. As a result, transmitted through the transmission pulley 33, the steering drive rod 27 has also rotated about the rod axis 28, so that the middle steering plate portion 19 compared to the position after Fig. 1 in the position after the Fig. 3 is now rotated counterclockwise about the pivot axis 20. As a result, the two outer steering plate sections 13 and 41 are each rotated about their pivot axes 14 and 42 in a clockwise direction via the hinge pin articulation points 18, 40. This causes the steering pin 16 of the trailer-side vehicle axle 8 in the Fig. 3 upwards and the corresponding steering pin 16 of the other vehicle axle 9 in the Fig. 3 was moved down. Accordingly, the result in the Fig. 3 shown steering angle of the two wheels 2, 4 of the trailer-side vehicle axle 8 and the wheels 3, 5 of the other vehicle axle 9. The toy vehicle can in the driving position to Fig. 3 with counter-steered wheels 2 to 5 drive a curve.

Fig. 4 shows a second steering position of the steering-Umstelleinrichtung 21. Compared to the first steering position after the Fig. 1 and 3 is displaced by pressing the change-over knob 22 of the carriage 24 a little way down. Accordingly, the position indicator pin 39 is compared with the changeover knob 22 a little further retracted into the chassis housing 7. Due to the change of the carriage 24 and thus the displacement of the pivot axis 20 transversely to the direction of travel, the positions of the articulation points on the hinge pins 18, 40 have moved. The pivot axes 14, 20, 42 are no longer, as in the positions after the Fig. 1 and 3 the case was, in a flight to each other. In the second steering position of the steering changeover device 21 is therefore a driving position of the four wheels 2 to 5 such. B. in the Fig. 1 not possible anymore. Fig. 4 shows a brought about a corresponding steering angle of the steering wheel 38 driving position of the wheels 2 to 5, which is also referred to as "dog walk". In this driving position of the wheels 2 to 5 is also a straight ahead of the toy vehicle possible, the direction of travel does not coincide with the vehicle longitudinal direction. In the driving position "Crab" after Fig. 4 In addition, all four wheels 2 to 5 drive in their own lane.

Fig. 5 shows a further driving position of the wheels 2 to 5 in the second steering position of the steering changeover device 21. Compared to the driving position of the wheels 2 to 5 after Fig. 4 are the wheels 2 to 5 in the position after Fig. 5 for a slight right cornering (see direction arrow 45) taken. Compared to the relative position after Fig. 4 are in relative position in the Fig. 5 the two steering plate portions 13 and 41 pivoted about their two pivot axes 14, 42 a piece in the clockwise direction.

The steering column Umstellgehäuse 34 is convertible between two steering column positions. In the first steering column position, the z. Tie Fig. 6 . 7 . 12 . 14 and 16 is shown, the steering column 37 of the trailer-side vehicle axle 8 faces. The transmission-toothed disc 33 is located in this position between the steering drive rod 27 and spray covers 46, which are attached to the bearing bodies 11 of the trailer-side wheels 2, 4. In the position after Fig. 16 engage behind Fixierlaschen 47 on the chassis housing 7 Fixierfüße 48, which are integrally formed on the underside of the steering column Umstellgehäuses 34.

The Fig. 17 and 18 show a further steering column position of the steering column Umstellgehäuses 34. In the position according to the Fig. 17 and 18 the steering column 37 is arranged above the further vehicle axle 9. Compared to the position after Fig. 16 the steering column Umstellgehäuse 34 is rotated about the rod axis 28 by 180 °. In addition, the steering column Umstellgehäuse 34 in the position after the Fig. 18 in comparison to the position after Fig. 16 pulled a piece far axially from the chassis housing 7. In the position after Fig. 18 the fixing feet 48 of the steering column Umstellgehäuses 34 are engaged by other fixing tabs 49 which are formed on the chassis housing 7 above the other vehicle axle 9.

To switch between the steering column positions after the Fig. 16 on the one hand and 18 on the other hand, the steering column Umstellgehäuse 34 is a piece far twisted about the rod axis 28 until the Fixierfüße 48 disengage from the fixing tabs 47 and 49 respectively. Subsequently, the steering column Umstellgehäuse 34 is rotated about the rod axis 28 by 180 ° and adjusted in its axial position relative to the chassis housing by pulling or pushing along the rod axis 28. In this axial displacement In the region of the desired steering column position, the fixing feet 48 are again brought into engagement with the fixing lugs 47 and 49 of the chassis housing 7.

The two steering column positions correspond to the two possible directions of travel of the toy vehicle. Various game situations approximated to the real role model can be created in this way.

All components of the chassis 1 are made of plastic.
