TRACK FOR TOY VEHICLES Filed Dec. 13, 1934 E. HORN 2 2,052,228

Patented Aug. '25, 1936 UNITED STATE TRACK FOB TOY-VEHICLES Ernst Horn, Nurembnrg, Germany Application December is, 1934, Serial No. 157,396 In Germany December 18, 1933 x- 20mm.

The invention relates to'track-bodies for toyvehicles, and more especially for toy-vehicles designed to travel on a track without rails, that is for toy-vehicles without flanges on the wheels;

the track-body, moreover, may consist of a single member or also or a plurality of parts iorm ing a closed track. The novelty of my invention flangeson the wheels, the said concavely arched track aflording a zone of travel that always acts in such a manner that the vehicle travellin thereon will invariably tend to follow the central line of the-track, even if temporarily deviating therefrom.

The track-body may be equipped with one or more tracks for guiding a toy-vehicle; in the latter case, for instance, two concentrical or parallel concavely arched guide-tracks may be provided on the track-body. said guide-tracks being separated from each other by an elevated zone.

In the accompanying drawing which forms part Ofthis specification I have represented an example of the construction 0! my present novel track-body for toy-vehicles showing in particular the concavely arched guide-track, Fig. .1 being a cross-section through the entire trackfigures showing two concentrically adjacent tion 'through the profile of a track-body having a single guide-track, and Fig. 4 a similar crosssection through the profile which inay advantageously be given to the guide-track at curvatures thereof.

Referring more particularly to'the drawing,

' the track-body consists of a closed guide-ring without rails, which guide-ring may be composed of several parts of alternately arched and straight conformation. In the construction represented body, Fig. 2 a plan-view taken on Fig. 1, both guide-tracks, Fig. 3 being an enlarged oross-sec- (c1. ec-zon in Figs. 1 and 2, the track-body is provided with two concentrically or parallelly adjacent guidezones l and between said guide-zones there is arranged the aforementioned elevated zone 5 which may, for instance, be properly masked to 6 represent a grass-surface.

The two guide-tracks or zones i according to my invention are of concavely arched coniormation so that the lateral rini's 2, as may especially be seen from Fig. 3, are positioned higher than 10 the middle portion at I. At curvatures the double track, the same as shown in the single track in Fig. 4, may be made with the one of its edges, 3. positioned higher than the other edge I so that the middle portion in. of the guide-track forms Iii an obliquely positioned archinterposed between the edges 3 and l.

A toy-vehicle, travelling along one of the concaveiy arched guide-tracks will always have the V tendency to move essentially along the central 20 line of the track, thus securing proper and regular travel of the vehicle.

With the aid of my novel track it will be possible to operate toy-vehicles having wheels without flanges in a manner to travel along a definite path and to be positively kept therein.

Evidently it is'immaterial whether the trackbody is provided with two or more guide-zones or tracks, as represented in Figs. 1 and 2, or whether a single guide-zone or track is used, shown in Figs. 3 and 4.

I claim:

'1. A track for wheeled toy-vehicles, said track comprising straight and curved portions, reversely cambered wheel engaging surfaces on said 35 track on either side of the center thereof, and said surfaces being so positioned that the treads of the wheels on opposite sides of said vehicles are engaged at all times by oppositely extending slopes of said surfaces to maintain the vehicles 40 on said track. I

2. The structure of claim 1, and the outer reversely cambered surface on said track being higher than the corresponding inner surface on the curved portions of said track.
