Tomaro, Maplewood, N.J., assignor to Remco Industries, Inc., Harrison, NJ. Filed Jan. 29, 1970, Ser. No. 6,880 Int. Cl. A63h 18/12 US. Cl. 46-243 7 Claims ABSTRACT OF THE DISCLOSURE A toy train system is described with a monorail track.

A train adapted to move on this track is provided with lateral supporting and vertical supporting wheels which ride respectively on side and upper surfaces of the track. The wheels are mounted in a track receiving channel of the train body and are both longitudinally and laterally spaced to engage the monorail in a track hugging manner. In one embodiment stanchions are attached to the underside of selected portions of the monorail track to obtain track elevations. High train speeds may be sustained along the elevated portions of the track without train derailment.

BRIEF DESCRIPTION OF THE INVENTION This invention relates to a toy train system. More specifically, this invention relatesto a toy train system with a monorail and a train structure shaped to envelop the monorail track for high speed stable movement over the monorail.

In a preferred embodiment in accordance with the invention a high speed toy train system is provided with a track structure generally in the form of a continuous monorail made of nonconductive material with conductive strips imbedded therein for electrical power transmission to the train. A train adapted to move on the monorail has wheels which ride on both upper and side surfaces of the track. The wheels are mounted in a track receiving channel of the train body and are spaced longitudinally along the track as well as laterally on both monorail track sides so that the train may embrace the monorail for stable train motion. Electrical power take off wipers are located in the track receiving channel of the train and contact the conductive strips which are preferably mounted in the top surface of the monorail. Upper track surface contacting vertical support wheels are also located in the channel of the train body with one of the latter wheels being driven by an electric motor whose driving power is obtained from the conductive strips. In a preferred embodiment the vertical support wheels ride between the imbedded conductive strips.

The track enveloping construction of the train body imparts to the toy train system excellent stability with little likelihood of toppling at high operating speeds. Portions of the monorail may be elevated with stanchions mounted to the underside of the track. When a track is elevated, upwardly and downwardly slanted ramps are formed; yet, train stability is maintained despite the high speed of a train 'as it travels along a downwardly slanted ramp.

FIGS. 6 and 7 are horizontal sectional views of a train locomotive such as take-n along a line 6-6 in FIG. 5 illustrating the position of the train wheels while on a straight and curved track segment respectively.

DETAILED DESCRIPTION OF THE INVENTION With reference to FIG. 1 a toy train system 10 is shown formed of a continuous monorail track 12. Monorail track 12 is formed of nonconductive material and is arranged in a figure 8 pattern with a portion 14 thereof elevated with stanchions 16. Track 12 is formed of a plurality of mating and interlocking monorail segments such as 18 some of which are curved. A train 20 is mounted on track 12. Train 20 is formed of a locomotive 22 which pulls cars 24. The track system depicted in FIG. 1 is arranged in a figure 8 pattern though it may be appreciated that other configurations may be used as desired.

Stanchions 16 are differently sized so as to provide gradually inclined track portions 26. Track 12 is further provided with electrically conductive strips 28-28 (See FIG. 2) embedded in the top nonconducting surface of the track to supply electrical power to a driving motor located within train 22. Electrical power for this purpose is fed to conductive strips 28-28 from a conventional transformer and rheostat control 30 with electrical leads 32.

The construction of a track segment 18 may be more clearly appreciated from the views in FIGS. 2 and 3. Therein, track segments 18 are shown with conductive strips vertically embedded in the track upper surface 34 and producing thereabove sufiiciently to enable electrical power pick-off wipers located in the locomotive 22 to make electrical contact therewith. As can be seen in FIG. 2 conductive strips 28-28 terminate in male and female ends whereby mating engagement may be made with other track segments 18 to form a continuous electrified track 12.

Track segments such as 18 have channel shaped bodies with smooth outwardly facing side surfaces 36-36. Preferably these side surfaces extend in a downwardly and outwardly lateral direction so as to form a trapezoidal crossesction with the bottom of surfaces 36-36 wider spaced from one another than their tops. The ends, 38 of track segments 18 are closed to form a rigid track segment whose side surfaces 36-36 are free from undulations and present a smooth high speed riding platform for train wheels. When in use, track segments 18 are placed with their open channels facing downwardly. The vertical track elevating supports 16 may then be placed in the track channels without interference with a train moving along the track. The top portions of vertical track supports 16 are, therefore, preferably so shaped as to wedge between the sides of track segments 18. A protrusion 39 and a recess 41 are each located in end surfaces 38 of a track segment 18 and mate in complementary fashion with like protrusions and recesses of other track segments 18. The protrusion 39 and recess 41 are so spaced from the male and female ends of conductive strips 28-28 that a tight frictional lock between adjacent track segments is obtained when male and female ends of conductive strips 28-28 are connected to one another.

Train 20 is so shaped that each of its components such as locomotive 22 and cars 24 envelop track 12. This construction is made possible by providing each train component with a track receiving channel 40. (See FIG. 4.)

This channel extends from the front towards the rear and is provided with side surface riding wheels 42 and vertical support wheels such as 44.

Side riding or lateral support wheels 42 are arranged in front and rear located pairs (See FIG. 5.) and the wheels in each pair are so laterally spaced to receive a track segment 18 between them and provide side rolling contact between locomotive 2'2 and track 12. As illustrated in FIGS. 4 and 5 lateral support wheels 42 rotate about vertical axes and are preferably in the form of conical roller elements whose conical shape is selected to provide a line contact with side surfaces 36-36 of track 12.

As may be observed in FIG. 5 vertical support of locomotive 22 and other train components is provided with wheels 44 rotating about horizontal axes. A front located vertical support wheel 44 contacts upper surface 34 of track 12 at a location generally between the pair of front located lateral support wheels 42. The other vertical support wheel contacts upper surface 34 of track 12 generally between the rear located lateral support wheels 42. Rear located vertical support wheel 44 is driven by an electric motor 46 through suitable gears 48 to rapidly advance locomotive 22 along continuous track 12'. As may be observed in FIG. 4 both the driwing vertical support wheel 44 and the front located vertical support wheel 44 contact upper surface 34 of track 12 between the parallel spaced conductor strips 28-28 Sliding contacts such as 50-50' are mounted in track receiving channel 40 to contact conductive strips 28-28 at upper portions thereof for locomotive power.

The location of vertical support wheels 44 is so selected as to reduce their lateral motion to a minimum when the train engages curved track segments. Thus, as clearly illustrated in the view of FIG. 5, each of the vertical support wheels 44 is located so as to contact upper track surface 34 in an area which falls generally midway of a line drawn between the contacts of lateral support wheels 42 with side surfaces 3646'. In this manner, lateral excursions of vertical support wheels 44-44 are reduced so that these vertical support wheels may ride between conductive strips 28-28 without interference therewith.

FIG. 7 illustrates the lateral displacement of portions of locomotive 22 as it engages a curved track segment 18'. As may be observed, portions 52-52 of the longitudinal slot protruding in front of front located lateral support wheels 42' and behind the rear located lateral support wheels 42 tend to approach the curved track. However, portions 52-52 of the locomotive body are laterally recessed so as to accommodate the curved track segments without interference. Portions 54 of channel 40 between lateral support wheels 4242' are so sized as to accommodate track curvatures.

On a curved track, vertical support wheels 44 operate in tangential direction relative to the track. The lateral support wheels 42, however, maintain locomotive 22 on the track regardless of this tangential effect and the speed of travel.

Having thus describe-d the elements employed in the high speed stable train system in accordance with the invention its advantages may be especially appreciated when high speed operating conditions are encountered. When the high speed train has rounded the curve 14 as indicated in FIG. 1 and commences to move along a downwardly inclined ramp 26 the construction employed with the train system of this invention maintains the train on the track. As the train quickly rounds the bottom located curve it ramps upwardly without toppling over.
