Drive for toy vehicles

The innovation concerns a drive for toy vehicles, which is not damaged even with the roughest treatment,

It is also known that ϊsf Ί <3 children, in their eagerness to play, put the vehicle on the ground with momentum, especially if it is a vehicle with a flywheel motor that has to be brought to the desired high speeds by pushing the vehicle. The success is that after a short time the bearings of the rear axles are knocked out and the toy vehicle makes a lot of noise. The innovation eliminates this disadvantage.

The innovation is that the base plate of the drive can rotate parallel to the rear wheel axle of the vehicle the chassis plate is connected and the freely pivotable

Side of the base plate by a spring of the chassis plate is pressed against the chassis plate from above. So if the toy vehicle is pressed from above, it works also the chassis plate downwards, but the drive can absorb this pressure by compressing the pressure spring, so that the rear wheel axle does not experience any impermissible load and therefore also no deflection of the axle bearings is more to be feared. It is advantageous to use a pin fastened to the chassis plate, through a recess on the side of the base plate opposite the bearing points protrudes upwards and its broad head a coil spring pushed over the pin presses against the top of the base plate. Will also be about that Coil spring inserted into a sleeve that is narrower than the head of the pen and at the same time shorter than the one under tension standing helical spring, then the spring stroke is limited in a simple manner and only the hard impact is absorbed, while a toy vehicle with a flywheel drive still has the option The flywheel remains at any desired position by moving the vehicle forward quickly under constant pressure Bring speed.

The drawing gives a drive to the innovation in Longitudinal section through part of a toy vehicle, for example again.

The drive contains a base plate 1 in a known manner with side walls 2 and a cross piece 3 with an upper bearing for a shaft 5 with a flywheel 6 and a worm 7. In the worm 7 engages a gear 8 which is attached to the rear wheel axle 9 of the toy vehicle.

According to the innovation, the base plate 1 is not rigidly connected to the chassis plate 10, for example by rivets, but has lobe-like extensions 11 that dun $ Rivets 12 articulated with lugs 13, bent up like a bearing block, of a sheet metal strip 14 attached to the chassis plate 10 is connected in such a way that the entire flywheel drive, including the rear wheel axle, revolves around the rivets 12 15 and 16 can be swiveled up in the direction of the arrows. However, this pivoting up is prevented by a helical spring 17, that of a broad head 18 of one on the chassis

presses the base plate firmly against the chassis plate 10 on this side.

If strong pressure is exerted on the toy vehicle 22 approximately at the point and in the direction of the arrow 23, i.e. approximately above the rear wheels 24, then the pressure is also transferred to the points indicated by the arrows 25 to 28, the counter pressure on the wheels in the direction of arrow 29 but causes the flywheel drive including the rear wheel axle 9 and the wheels 24 to pivot under compression of the spring 17 around the rivets 12 in the direction of arrows 15 and 16 until the broad head 18 of the pin 20 at a sleeve 30 abuts, surrounding the coil spring 17, but ■> shorter and shorter than the spring in the biased position, the length of the sleeve 30 is selected such that the spring can fully receive 17 a substantial impact in the direction of arrow 23 , but still allowed to bring the flywheel drive to any desired high speed with calm and strong pressure and simultaneous forward movement of the vehicle 22.
