Description

The present patent application takes the priority of the German utility model application DE 20 2015 100 263.7 claim, the contents of which are incorporated herein by reference.

The invention relates to a toy vehicle, in particular a model toy vehicle. Furthermore, the invention is directed to an arrangement of a work roll and a removable mounting bandage for such a toy vehicle. In particular, the toy vehicle enables the imitation of the real environment.

Toy vehicles are known for example from the DE 10 2012 022 638 A1 , of the DE 1 745 170 U and from the DE 1 005 419 A ,

The invention has for its object to develop a toy vehicle such that a particularly diverse and realistic gaming experience with this is possible. Furthermore, a corresponding arrangement is to be created.

This object is achieved by the features specified in claims 1 and 15 features. The core is that a mounting bandage is releasably connectable to a work roll main body or is removable from the work roll main body. The assembly bandage can therefore be arranged around the work roll main body or around the work roll. It is mountable and dismountable. When assembled, the mounting bandage forms an outer shell, as it were, with respect to the work roll.

Playing with the toy vehicle is possible both with the assembly bandage removed and with the work roll main body associated assembly bandage. With removed assembly bandage is the work roll main body with its lateral surface or tread, for example in the form of a smooth-bandage or smooth-coat bandage in contact with the ground. When connected to the work roll main body mounting bandage, however, is the assembly bandage itself with its tread or lateral surface in contact with the ground.

The work roll main body preferably has an outer diameter of between 4 cm and 20 cm, more preferably between 6 cm and 15 cm.

Preferably, the mounting bandage is made of plastic. It is preferably annular in cross section.

It is useful if the assembly bandage of the work roll main body without tools, so without tools, is removable or removable. Conveniently, the assembly bandage without tools, so without tools, attached to the work roll main body or mountable.

It is advantageous if the work roll is rotatable about a longitudinal central axis. For this, the toy vehicle preferably has at least one corresponding bearing device.

Conveniently, the work roll main body and the mounting bandage in the assembled state of the assembly bandage are non-rotatable with each other connected. A relative rotational movement between these is then prevented.

Further advantageous embodiments of the invention are specified in the subclaims.

The design of the assembly bandage, divided into a plurality of bandage lower body, which are each detachably connected to the work roll main body, allows an extremely simple assembly of the assembly bandage on the work roll main body. A particularly simple disassembly of the assembly bandage is also possible. It is expedient if the bandage lower body are formed identical to one another. The bandage lower body are preferably individually and independently removable or mountable. There may be between two and sixteen bandage lower body.

The bandage lower bodies are each substantially bowl-like. They are preferably designed as sheath segments. Each bandage lower body conveniently extends in the assembled state over an angular range of 22.5 ° to 180 °, in particular from 45 ° to 90 °, about a longitudinal center axis of the work roll. In the assembled state of the assembly bandage this has a circumferential closed lateral surface.

There may be a gap between adjacent bandage sub-bodies at least in places, so that there the bandage lower bodies are separated from one another. Adjacent bandage lower body can touch each other at least but also or alternatively partially edge. Conveniently, each bandage lower body is at least partially inside on the work roll base body.

The embodiment according to the dependent claim 2 allows a quick assembly and disassembly of the assembly bandage.

According to the dependent claim 4, the bandages lower body are attached exclusively to the work roll main body. An attachment of the bandage lower body to each other or among each other thus remains.

The embodiment according to the dependent claim 5 prevents a relative movement between adjacent drum sub-bodies in the direction of the longitudinal center axis of the work roll. Preferably, the adjacent bandage lower body engage each other via their edge contours. The same applies to the subclaims 6 and 7.

The locking connection according to the dependent claim 8 allows a functionally reliable and fast attachment of the bandage lower body to the work roll main body. A simple removal or removal of the bandage lower body is also possible.

It is advantageous if the at least one locking element according to the dependent claim 9 has at least one locking lug. Conveniently, the at least one latching counter element is designed as a receptacle for the latching element. A reverse training is alternatively possible.

If the mounting bandage is mounted according to the dependent claim 12, the operation "padfoot bandage" of the toy vehicle is possible. The padfoot bandage is in reality intended for use on cohesive soils. The stamp feet are arranged on the outside. They are conveniently identical. It is an advantage if the stamp feet in Rows and / or columns are arranged. Alternatively, the assembly bandage and / or the work roll main body can be designed as a belt wheel bandage, as a lattice wheel bandage, as a disc wheel bandage or as a polygonal bandage.

According to the dependent claim 13 of the work roll main body has a smooth-bandage or smooth-coat bandage, which is annular in cross-section and is substantially free of elevations or depressions. The smooth bandage differs so constructively from the padfoot bandage. In particular, the smooth bandage differs in its surface or its surface profile from the padfoot bandage. With the smooth-bandage the mode of operation "smooth-bandage" of the toy vehicle is possible. The smooth bandage is in reality preferably intended for compacting asphalt or non-cohesive soils.

The toy vehicle according to the dependent claim 14 is designed as a construction machine, which is used in reality essentially to compact soils or ground. It is advantageous if the frame part of the compactor comprises or carries a driver's cab. It is useful if the frame part, for example, has an engine compartment. The machine frame is preferably arranged in front of the frame part.

Conveniently, the machine frame and the frame member are in articulated connection with each other to allow steering of the toy vehicle. An articulated steering can be so available. Alternatively, the machine frame and the frame part are rigidly connected. The frame part preferably has at least one wheel for ground contact. Alternatively, a further work roll is mounted in / on the frame part, with their Work roll main body another mounting bandage removably connected or connectable.

The dependent claims 2 to 14 may also be the subject of the independent claim 15.

First, referring to the Fig. 1 to 3 a trained as a toy vehicle roller train comprises a front machine frame 1 and a rear frame part 2 and a vertical bending axis predetermining articulated joint 3, which connects the machine frame 1 and the frame part 2 hinged together.

The machine frame 1 comprises a horizontally extending, rigid bearing frame 4 and a work roll 5, which is rotatably mounted in the bearing frame 4 about its horizontally extending longitudinal central axis 6 in a running direction 7. The longitudinal central axis 6 forms an axis of rotation.

The frame part 2 is frosted. It includes two rotatably mounted wheels 8 and a driver's cab 9 and a rear engine compartment 10. In the engine compartment 10 is preferably no functioning engine, since the toy vehicle conveniently displaced by hand, in particular pushed.

The bearing frame 4 comprises two outer cross members 11 and two cross members 11 interconnecting outer bearing support 12, which extend perpendicular to the cross members 11 and extending parallel to each other. The bearing carrier 12 extend parallel to a direction of travel 33 of the toy vehicle. By the cross member 11 and the bearing bracket 12, a laterally limited receiving space 13 is formed for the work roll 5. It is appropriate when the bearing frame 4 is composed of two frame-like components, namely an upper frame part and a lower frame part.

The arranged adjacent to the frame part 2 cross member 11 is articulated via the articulated joint 3 with the frame part 2.

Each bearing support 12 has substantially centrally a bearing means 14, which is formed according to this embodiment as a circular cross-sectional bearing receptacle.

The work roll 5 comprises a work roll main body 15, which in turn comprises two circular disk-like, outer bearing discs 16 and a smooth bandage 17.

The bearing discs 16 are parallel to each other. They are preferably non-rotatably connected to the smooth bandage 17. Conveniently, the bearing discs 16 are inserted into the smooth bandage 17 laterally outside. Each bearing disk 16 has a central bearing means 18, which according to this embodiment is designed as an axially outwardly projecting bearing journal and is adapted to the respective bearing means 14. Each bearing disk 16 also has, on the outside, a plurality of nose-like latching counter-elements 19, which project in each case in the direction of the longitudinal central axis 6 to the outside and have a latching counter-surface 20 facing the longitudinal central axis 6. Each locking counter-element 19 has an outer, oblique latching counter-flank 21, which projects axially from radially outward in the direction of the longitudinal central axis 6 and extends straight up to the latching counter-surface 20. The locking counter-elements 19 have an identical angular distance about the longitudinal central axis 6 to each other. Overall, here are arranged on each bearing disc 16 six locking counter-elements 19. The locking counter-elements 19 are structurally identical.

In the described compactor, the so in Fig. 1 is shown, it is a game ready or playable toy vehicle. The compactor has on his wheels 8 and the work roll 5 while playing ground contact. When moving the roller in the direction of travel 33, the work roll 5 rotates about its longitudinal central axis 6 in the running direction 7. The latching counter-elements 19 are here without function or free. An opposing displacement of the roller is naturally possible alternatively, resulting in a reverse rotation of the work roll 5.

In order to switch from the "smooth-bandage" mode of operation to the "padfoot bandage" mode of operation, a plurality of bandage lower bodies 22 can be detachably or detachably fastened to the work roll main body 15.

The bandage lower body 22 are identical. They are elongated. Each bandage lower body 22 is formed substantially cup-shaped or segment-like.

Each bandage lower body 22 has, for contact with the ground, a cup-shaped running region 23, from which a multiplicity of block-like stamping feet 24 project radially outward. Each bandage lower body 22 has a leading edge contour 25 in the running direction 7 and a trailing edge contour 26 trailing in the running direction 7. The edge contours 25, 26 of each bandage lower body 22 extend opposite one another. Between these lies in the running direction 7 in each case an identical distance. The edge contours 25, 26 have a course that deviates from a parallel to the longitudinal central axis 6 course. The leading edge contour 25 has a projecting in the running direction 7 central area, while the trailing edge contour 26 of this bandage lower body 22 has a corresponding bulge. Each leading edge contour 25 projects from axially laterally outside in the center in the running direction 7.

Each bandage lower body 22 has axially laterally outside each a final contour 27 which extends between the edge contours 25, 26 of the respective bandage lower body 22. Each bandage lower body 22 thus has two end contours 27, which are opposite to each other and parallel to each other. In the area of each end contour 27, an edge web 28 projects radially inwards. From each edge web 28 in turn jumps in the middle of a side part 31 radially inward before, which has a radially outwardly open latching receptacle 29. Each latching receptacle 29 is bounded by a radially inner latching surface 30, which is preferably flat and is turned radially outward in the assembled state of the respective bandage lower body 22. The locking receptacles 29 each have a width in the running direction 7, which corresponds approximately to the corresponding width of the respective locking counter-element 19.

For use of the toy vehicle as a "padfoot bandage", the individual bandage lower bodies 22 are attached to the work roll main body 15 to form a padfoot bandage 32. In this case, the latching receptacles 29 are latched to the latching counter-elements 19. In the locked state, the latching mating surfaces 20 and the latching surfaces 30 of the respective bandage lower body 22 are arranged opposite one another, whereby the bandage lower bodies 22 are fixed radially outward on the work roll main body 15. The bandage lower body 22 are at their running area 23 outside of the smooth bandage 17, so that the smooth bandage 17 is surrounded by these and the bandage lower body 22 are fixed radially inward. The side parts 31 are arranged laterally outside with respect to the bearing discs 16, so that the bandage lower body 22 are axially fixed to the work roll main body 15. Each locking receptacle 29 has in the running direction 7 to a width which corresponds approximately to the corresponding width of the locking counter-element 19, so that in the running direction 7 between the bearing discs 16 and the respective bandage lower body 22 is substantially a play-free connection. The toy vehicle is also ready to play or playable with mounted padfoot bandage 32.

During assembly of the bandage lower body 22 slide the side members 31 on the locking counter-flank 21 from radially outward to radially inward and are thereby deflected axially outwardly until the locking counter-surface 20 is reached. The side parts 31 then spring back into their undeflected position, whereby the latching connection described between the bandage lower body 22 and the work roll main body 15 is created. Adjacent bandage lower bodies 22 are unattached to each other.

When associated with the work roll main body 15 padfoot bandage 32 is the padfoot bandage 32 or stand their pestles 24 when playing in contact with the ground. The bandage lower body 22 together envelop the smooth bandage 17 and form an outer jacket. The smooth bandage 17 then has no contact with the ground while playing. It is then virtually functionless and lifted off the ground. The smooth bandage 17 is then within the padfoot bandage 32nd

The bandage lower bodies 22 are removable from the work roll body 15 again to return to the "plain bandage" mode of operation to be able to. To release the latching connection between drum base body 22 and work roll main body 15, the corresponding side member 31 must be directed axially outward to dissolve the positive connection between the associated locking counter-element 19 and the locking receptacle 29.

The terms "radial" and "axial" used generally refer to the longitudinal central axis 6.
