Description

Driving toys

The invention relates to a driving toy with a vehicle chassis that can be moved by wheels on roadways and a vehicle body that can be fixed to it.

In known driving toys, the body is designed with a predetermined design and is laboriously connected to the chassis by means of bends or gill means. Apart from the fact that these driving toys require interventions in the interior of the vehicle, for example for the purpose of changing the power source or complicating the handling of the tools, the maintenance of the body is also imperative.

Replacing the body is either not possible or requires a complex adjustment to the chassis or requires one of the respective ones

Body-adapted chassis.

It is an object of the invention to provide measures for attaching any bodies to the vehicle chassis while maintaining the same vehicle chassis.

According to the invention, this object is achieved in that the vehicle chassis has a number of pegs and the driving on the chassis side of the chassis with the spacing and assignment of the pins has a fixed number of sleeves that can be pushed onto the pins of the vehicle chassis. The pins and sleeves are preferably arranged in a row on the vehicle chassis or on the vehicle body, a multi-row arrangement of the pins or sleeves having proven to be advantageous and providing stable connections. In this way, the prerequisite for exchanging any bodywork on a vehicle chassis that can be maintained unchanged is given by a simple plug-in process. The body to be used on the vehicle chassis can be fixed or removed without tools. To compensate for tolerances, the pins are expediently provided with fitting webs projecting over the circumferential surface of the same, which result in a clamping fit when the sleeves are pushed on by deformation. It is understood that fitting webs can also be arranged on the inner circumferential surface of the sleeves, while the pins are smooth on the outside.

In an embodiment of the toy vehicle it is provided that the vehicle chassis is formed in a box-like manner by two vehicle chassis parts which are arranged one above the other and can be joined together in a plane parallel to the roadway plane, both of which are arranged by means of pins arranged on one chassis part and arranged on the other chassis part the pegs can be slid together with one another. The vehicle chassis thus formed is used to hold the wheels in addition to Power sources and gears as well as the drive motor. A chassis part can expediently be provided with a receiving chamber for a low-voltage power source and a receiving space for the drive motor, while the other chassis part receives a gear train, at least partially the electrical conductors and a switch device. Requests or pinches arranged on the chassis parts can be used as hold-down devices for the current source and, for. B. serve as electrical conductors formed by loosely inserted conductor tracks. The drive motor can be held in the receiving space of the one chassis part by means of clamping voltages. The electrical coupling of the drive motor and the electrical conductor is effected simply by pressing the same against one another.

In a further embodiment, it is provided that the two chaise parts are provided with half-shells which complement one another for bearings for the vehicle wheels or wheel shafts. In this case, in particular the front vehicles can be stacked in two. extending identical half shells can be mounted, one of which is arranged on an extension of the upper chassis part and the other on the lower chassis part. However, the rear vehicle wheels are expediently arranged on a shaft which is guided in recesses in the chassis parts.

It is also provided that the front vehicle wheels each have a cylindrical stub axle in the half-shells engage in a freely rotatable manner and that the stub axles for axially fixing the wheels in the half-shells by means of stub axles which protrude from the stub axles and which extend beyond the peripheral surfaces of the stub axles or with annular body sections engage in an annular groove formed in the half-shells. The axle stubs are preferably formed by pipe or sleeve sections. The arrangement enables the wheels to be held by simple plug-in operations, the stub axles contributing to a low-backlash holding of the wheels by a relatively large diameter, while the ring bodies or the ring body sections keep axial bearing play within narrow limits . The wheels can be held on the chassis without tools and the usual molding of metal parts as axles or shafts is no longer necessary.

According to a preferred embodiment, the half-shells can be supported against one another axially and transversely to the longitudinal axes of the half-shells by means of grooves and tongues formed in the common separating surfaces.

For this purpose, a half-shell expediently has the springs, while the associated other half-shell is provided with grooves. There is also the possibility of providing a tongue on each half-shell and a groove diametrically to this.

It is understood that the ring body and the ring grooves can have any cross-sectional shape and cross-sectional size. According to a preferred embodiment, the ring bodies and the ring grooves are covered with a trapezoidal cross-section. The wedge-shaped surfaces of the trapezoidal shape result in a particularly playful mounting of the wheels on the chassis through mutual support. It is possible to form ring bodies and ring grooves with semicircular cross sections.

The invention is illustrated using exemplary embodiments in the drawing. It means:

In the figures, 1 denotes a chassis that is known to be movable on roadways (not shown) by front wheels 2 and rear wheels 3. A body of any design is designated with 4. net, which is connected to the chassis 1. In the exemplary embodiment, the chassis 1 is formed by a lower chassis part 1 ″ and an upper chassis part 1 ′ *, which together form a box-shaped chassis part 1. The two chassis parts 1 ¹ and 1 ″ ε can be connected to one another by a sliding process, with the chassis part 1 ′ ¹ friction pins ¹ arranged in sleeves 6 of the chassis part 1. The chassis part 1 'is provided near the front end on both sides on the outside in the areas of recesses 9 with half-shells 7 which, when the chassis part 1 is plugged in "'with half-shells 7', which are arranged on extensions 8, are supplemented to wheel bearings. In addition, the chassis part 1 'has, in the region of further recesses 10, a half-bearing opening 11 for a drive shaft 12 of the rear wheels 3. In the recesses 10 in the connecting both Chasεisteile dip l ^1, l ¹ 'wei¬ tere extensions 13 with bearing half openings 14 a. Inside the chassis part 1 'supports connection springs 15, 15' which can be connected to a drive motor 17 via electrical conductors 16, 16 '. The chassis part 1 ' ¹ receives a battery (not shown) in a receiving chamber 32 and is provided with a receiving space 33 for the drive motor 17. The electrical conductor 16 is connected to the drive motor by pressing it on an insulated contact 18 of the drive motor 17 and the electrical conductor 16 'is connected by means of a slide switch 19, which is in a recess 20 in the chassis part 1 is movable in the longitudinal direction. The slide switch 19 has a wedge-shaped requisition 21, which Bend 22 lifts the electrical conductor 16 "during displacement movements and places it with its free end against another motor contact, for example the motor housing. 23 denotes webs for fixing the electrical conductors 16, 16 ' , while there are 24 formations for fixing the same to the chassis part 1 '.

The drive motor 17 acts via a pinion 25 on a gear wheel 26 and a pinion 27 which meshes with a further gear wheel 28 which is fixedly arranged on the drive shaft 12 of the rear wheels 3.

The chassis part 1 ″ has pins 29 at the top, which in the exemplary embodiment are formed in two rows next to one another. The body 4 can be pushed and connected to the pins 29 by means of sleeves 30 (FIG. 1). For the purpose of compensating for manufacturing tolerances, the pins 29 can have fitting webs 31 in the outer circumferential surface, which bring about a secure fixation of the body 4 on the chassis 1 by deformation.

In the case of a toy vehicle, the front wheels 2 are individually connected to the chassis 1 so that they can rotate freely. For this purpose, as can be seen in particular in FIG. 10, the front wheels 2 engage with a tube or sleeve section as an axle stub 37 in bearings of the chassis 1 formed by half-shells 7, 7 '. To axially fix the front wheels 2, stub axles 37 are provided with an annular body or annular body sections projecting over the circumferential surface of the same 38 provided which engage in annular grooves 39 of the half-shells 7, 7 '.

For the mutual alignment of the half-shells 7, 7 ", one half-shell 7 has springs 40 and the other half-shell 7 '. Grooves 41. When the springs 40 are immersed in the grooves 41, the alignment is carried out automatically by a simple sliding process.

For the attachment of the front wheels 2, it must first be assumed that the two chassis parts 1 'and 1''are held one above the other at a distance. In this position, the chassis parts of the front wheels 2 can, with its stub axles 37 in the bottom half-shells l ¹ is inserted and by subsequently pushing the obe¬ ren chassis part, the upper half-shells 7 "with the un¬ direct half-shells l 'are supplemented to peripherally closed warehouses, that the stub axles 37 are kept axially free of play or with little play by means of the ring body 38.

In the exemplary embodiment in FIG. 7, annular body sections 38 'arranged on the axle stubs 37 are used for axially fixing the front wheels 2.
