Abstract

A toy vehicle system, such as a battery powered toy railway, comprises a vehicle adapted to run on a base which guides the vehicle. The vehicle has three travelling states, viz. forward, stop and reverse. The base includes at least one switching section provided with a guide adapted to cooperate with a switching element on the vehicle when the vehicle enters said switching section from either direction. The guide may be set for travel in a selected direction or ''''stop'''' and thereby changes over the switching element to correspond to the desired setting unless the switching element is already at that setting when the vehicle enters the switching section. The guide may be movable by means of a lever between three transverse positions corresponding to the three settings, or may be movable between only two of these settings or may have a fixed setting.

3 Sheets-Sheet 2 Patented May 1; 1973 3 Sheets-Sheet 5 TOY RAILROAD VEHICLE AND SWITCHING SECTION The invention relates to a toy vehicle system in which the vehicle runs on a base which guides the vehicle, such as a toy railway driven by an electric battery, and in which the travelling states of the vehicle (forward, stop and reverse) are controllable by a switching section on the base.

In toy railways which have a self-contained power supply, direct external control by varying the current or voltage which is fed to the vehicle is not practical. Normally, the child playing with such railways operates them manually by actuating a switching device on the vehicle, whereupon the vehicle continues to run until it is again gripped manually and switched off or reversed. The possibilities of playing with such a railway are very limited, and the vehicle is readily damaged by constant handling. Railways having a switching section are already known, the switching section acting upon two separate switching levers for stop and reverse, in order to stop or change the direction of travel of the vehicle. However, these switching sections have the great disadvantage that they require great attention from the child playing with the toy, since change of direction is dependent upon the direction and the position (forward or reverse) in which the locomotive enters the switching section.

A feature of the invention is to provide a toy vehicle system of the initially mentioned kind in which change over to the individual travelling states may be effected in a particularly simple manner and in which the possibilities of play thus obtained are considerably increased.

In accordance with the invention, a switch having switching positions for the travelling states is mounted on the vehicle, the switching element of which switch The invention is further described by way of example, with reference to the accompanying drawings wherein:

FIG. 1 is a side elevation of a locomotive,

FIG. 2 is a partially broken-away longitudinal section through the locomotive,

FIG. 3 is a section taken on the line III-III in FIG. 2, FIG. 4 is a plan view of a switching section in the rail track,

FIG. Sis a section, taken on the line V-V in FIG. 4, with a broken-away fragmentary view of a locomotive,

FIG. 6 is a view seen in the direction of the arrow VI in FIG. 4,

FIG. 7 is a diagrammatic plan of a rail track having switching sections as illustrated in FIG. 4,

FIGS. 8 and 9 are plan views of different embodiments of switching sections, and

can co-operate with a guide device which is arranged on the switching section insertable into the base, wherein, when the vehicle enters the switching section from any optional direction, the guide device can changeover the switching element to that travelling state which corresponds to the selected direction of travel or stop setting of the guide device irrespective of whether the vehicle is travelling forward or in reverse.

When the terms locomotive and rail are used hereinafter instead of vehicle and base, this is intended to refer to all vehicles which travel on rails or track-like bases, such as toy cars on guideways. It will be appreciated that the possibilities of playing with such a system are increased to a considerable extent. At each switching section of which a plurality may be arranged in a preferably endless track, the child playing with the toy sets the desired direction of travel which a locomotive or a train is to assume when it reaches this section irrespective of whether the locomotive is travelling forward or in reverse or irrespective of the direction of travel in which it enters the section. This renders possible a combination of possibilities of play which have scarcely any disadvantages compared with a conventional electric railway supplied by an external source of energy. However, at the same time, operation is so simple that even the smallest child can play sensibly with the system. Thus, there is provided a toy which may be used by children of many age groups.

FIG. 10 is a diagrammatic plan. view of a rail track having switching sections as illustrated in FIGS. 8 and 9.

A toy locomotive 11 is illustrated in FIGS. 1 to 3. It is driven by batteries 12 which are accommodated in its boiler and which feed an electric d.c. motor 13. One of the total of three axles 15 of the locomotive is driven by the motor by way of a worm drive 14. For the purpose of changing the batteries, the upper portion 16 of the boiler is removabl after a snap device 17 has been disengaged. Electriczil power is fed to the motor 13 from the batteries 12 by way of an electrical switch 18 which can assume three switching positions for three travelling states, i.e., for forward and reverse travel and for stopping the locomotive.

' For this purpose, the switch has a contact bridge 20 which is connected to the chassis 19 of the locomotive and on the top of which is provided an outer conducting region 21 and an inner conducting region 22. The two regions are connected by way of connection wires 23 to the terminals of the battery. The

regions

21 and 22 are insulated from one another and arearranged such that insulated places 24 are formed between the regions 21 overlapping the two outsides, and the center region 22. Two contact springs 25, 25' co-operate with the contact bridge and are connected to the motor term inals by way of connection wires 26; The

contact springs

25, 25 are arranged on a pivotable switching element in the form of a switching lever 27 which is pivotable about a screw 28 serving as a pivot. The switching lever 27 may be pivoted manually by way of a hand lever 29 which projects towards both sides from the chassis 19 of the locomotive and which is pivotable together with the switching lever. An actuating pin 30 is mounted at the free end of the switching lever 27 and projects downwardly from the locomotive chassis 19 through a slot 31 provided in the latter.

The switch 18 acts as an off switch and reversing switch by virtue of the fact that, when in one outer position (upper position in FIG. 3), the contact spring 25 is in contact with the region 21 and the contact spring 25' is in contact with the region 22. When in the central position illustrated in FIG. 3, the two contact springs are in the region of the insulating places 24, so that the flow of current is interrupted, while, when in a lower position, the contact spring 25 is in contact with the region 21 and the contact spring 25 is in contact with the region 22. Thus, in the respective outer positions (not illustrated; top or bottom in FIG. 3), the motor runs in different directions of rotation.

A switching section 32 is illustrated in FIGS. 4 to 6. In order that it may be connected into the normal track for the railway 11, the switching section 32 also has rails 33 which, however, do not have to act as current conductors and thus may be made relatively simply from plastics material. A guide 34 having a guide slot 35 is arranged between the rails 33. As may be seen from FIG. 5, the guide 34 is substantially channelshaped. It is of relatively great length and has sloping entry portions 36 at each end. The guide 34 is mounted on a slider 37 which engages below the rails 33 and which is horizontally displaceable in a base plate 38 and transversely of the rails. The swivel pin 40 of a lever 41 is journalled in a sleeve-like bulge 39 in the base plate. A bulge 42 in the slider engages over the bulge 39 and has an oblique slot 43 which forms a guideway and into which engages a transverse pin 44 on the swivel pin 40. During rotation of the swivel pin 40, the pin 44 can move in a slot 45 which extends across a portion of the periphery of the bulge 39. The lever 41 and its swivel pin, the slotted guideway 43 and the slider, and the associated parts described, form an actuating device 46 for the guide 34.

The slider 37 is made from plastics material like all the parts of the switching section 32, and a portion of the slider 37 is separated by a slot and forms a resilient detent 47 whose lug can engage into any one of three recesses 48 in the base plate in order to arrest the slider resiliently in a respective one of the three positions.

The locomotive and the switching section co-operate in the following manner:

When the locomotive 11 is placed on the switching section, as is partially illustrated in FIG. 5, the actuating pin extends into the guide slot in the guide 34. In the embodiment illustrated in FIG. 5, the lever 41 is located in its upwardly directed position, the pin 44 is in a central position in the slotted guideway 43, and the slider 37 holds the guide 34 in its central position. Accordingly, the pin 30, and thus the switching lever 27, are in their central positions. The switch 18 is switched off and the motor 13 carries no current. If the lever 41 is now pivoted, for example upwardly in FIG. 4 or to the right in FIG. 6, the pin 44 moves in the same direction of rotation and, owing to the slope of the slotted guideway 43, pushes the slider 37 to the left in FIGS. 4 and 5. The guide 34 drives the actuating pin 30 in the same direction, so that the switching lever 27 (FIG. 3) is pivoted in an anti-clockwise direction, i.e., upwardly. The leads 23 and 26 are connected to the battery and to the motor in such a manner that this movement of the switching lever 27 corresponds to reverse travel of the locomotive.

If it is now assumed that the locomotive had been placed on the switching section 32 in the reverse position, i.e., with the forward direction of travel of the locomotive towards the top in FIG. 4, the switching lever 27 would have been pivoted in the opposite direction, so that the locomotive would have moved off in forward travel. Thus, with the selected setting of the lever 41, the locomotive would have left the switching section 32 in the same direction of travel irrespective of which way round the locomotive has been placed on the switching section. Preferably, the actuating device is constructed in such a manner that the direction in which the locomotive leaves the section always coincides with the direction in which the lever 41 is pointing. It is also to be noted that it is completely immaterial as to which way round the switching section is inserted into the rail track. In the above-described construction of the actuating device, the locomotive always leaves the section in the direction in which the lever is pointing.

A locomotive, which enters the switching section in the direction in which the lever is pointing, always has its actuating pin 30 in a position which coincides with the position of the guide slot 35 in the guide 34. The locomotive travels through the switching section in an unobstructed manner. When a locomotive enters the switching section in the opposite direction to the direction in which the lever 41 is pointing, its guide pin 30 is in the opposite position to the position of the guide 34. The guide pin 30 then strikes against the corresponding sloping entry portion 36 and is changed over to the opposite direction by way of the stop position. The locomotive then immediately leaves the switching section in the direction from which it came.

In the central position illustrated in FIGS. 4 to 6, the actuating pin is also guided into the central position by the guide 34. As may be seen from FIG. 3, the contact springs 25, 25 are on the insulating places 24 of the contact bridge 21, so that the flow of current is interrupted and the locomotive remains stationary or stops. When the switching section 32 is in the illustrated stop setting, the actuating pin 30 on a locomotive 11 entering the switching section 32 from any direction of travel is guided into the central position by the sloping entry portions, and the locomotive stops.

It will be seen that all functions of the locomotive may be controlled by way of the switching section, both when putting the locomotive into operation (throwing the lever when the locomotive is stationary on the switching section) and automatically when the locomotive enters the switching section. However, in order that the locomotive may be placed on the rail track and put into operation at places at which there are no switching sections, there is provided the hand lever 29 by means of which forward and reverse travel may be set and by means of which the locomotive may be stopped.

It may readily be seen that this manual and automatic actuating possibility for the travelling states of the locomotive provides numerous possibilities of play. By virtue of the obvious association of the position of the lever and the direction of travel, the child playing with the railway can control the direction of travel of the train manually and can also pre-programme the direction of travel, so that the train changes its direction of travel and travels over specific portions of the track without external influence. A simple example is illustrated in FIG. 7 which shows a rail track 50in the form of an external oval and an inner circle, the two self-contained loops being interconnected by points 5 l. The main directions of travel which have been set are indicated by arrows adjacent the points. Three switching

sections

32, 32' and 32" are arranged in the rail track 50, and their directions of travel (positions of their levers 41) which have been set are also indicated by arrows.

A train travelling forwardly in the clockwise direction from the switching section 32 travels up to the switching section 32" where it is reversed and then travels along the lower inner arc up to the switching section 32' where it is again changed over to forward travel and returns to the switching section 32. It will be seen that a slightly larger system provides many possibilities of variation which enable a child to devise a large number of such functions for himself.

It is possible, within the scope of the invention, to provide a large number of modifications of the described embodiment. Thus, for example, the slotted guideway for controlling the actuating device 46 may be replaced by a different control arrangement for the guide 34, although, preferably, parallel displacement of the guide in the plane of the rails is retained, since this has proved to be particularly advantageous. The points 51 may be of conventional construction, as well as the couplings mounted on the locomotive 11 and the associated carriages, although it must be ensured that they are simple to operate in order to ensure that the railway may be used even by young children.

A switching section 32 inserted into a rail track 53 is illustrated in FIG. 8. The switching section 132 comprises a single plastics material member constructed as a flat member 64 in the form of an arrow pointing upwardly when referring to FIG. 8. The switching section 132 may be engaged or snapped between the rails 33 by means of two transverse ribs 52 formed on the underside of the flat member 64. It will be seen that this enables the switching section 32' to be secured at any optional position on the rail track and in any optional direction. A projection forming a guide 34' extends upwardly from the flat member 64. The guide 34 has a long guide surface 53 extending obliquely to the direction of travel, and a shorter guide surface 54 which also extends obliquely to the direction of travel.

A switching section 132" is illustrated in FIG. 9 and may also be inserted between rails 33. The switching section 132" has a flat member 55 which is made from plastics material and which may be clamped between the rails 33 at any optional point by means of transverse ribs 52 formed on the underside of the switching section 132". An actuating member 56 in the form of an arrow is pivotally secured to the flat member 55 by means of a pivot pin 57 shown by a dotted line in FIG. 9. A switching lever 58 is secured to the actuating member 56 and extends below the flat member 55 and engages through an opening (not illustrated) in the flat member 55.

The actuating member 56 is urged into the position illustrated in FIG. 9 by means of a plastics material spring (not illustrated) integrally formed with the flat member 55, so that the actuating member lies substantially parallel to the rails 33. As is shown by the dotted arrow 60, the actuating member 56 may be pivoted about a pivot pin 57 by pivoting the switching lever 58 in the direction of the dash-dot arrow 59.

A guide 34" in the form of an upwardly extending rib is arranged on the actuating member 56. The guide 34" has a sloping or bent guide surface 61 directed towards the pivot pin 37, and a guide surface 62 which, when the actuating member 56 is in its normal position illustrated in FIG. 9, extends substantially parallel to the rails 33 and is located substantially in the center between the rails 33.

The flat member 55 has an upwardly extending projection 63 adjacent the guide surface 62.

The mode of operation of the switching sections will be described hereinafter with reference to FIGS. 8 to 10. When the locomotive l 1 is placed on the rails, the actuating pin 30 can engage the guides 34', 34". When the locomotive l 1 travels through. the switching section 132 from the top in FIG. 10, its actuating pin is in a position in which the actuating pin is not actuated by the guide 34'. Thus, the actuating pin 30 runs past the guide surfaces 53, 54 without a switching operation taking place, irrespective of whether the locomotive is travelling forward or in reverse. Thus, the locomotive travels straight through the switching section 132. When the locomotive enters the switching section 132", the actuating pin 30, which had been directed towards the right during travel from top to bottom in FIG. 10, is urged by the guide surface 61 into the central position and is guided along the guide surface 62. The central position of the actuating pin 30 is the stopping position of the locomotive, and the locomotive is arrested. If the momentum of the locomotive should be too great, the projection 63 ensures that the locomotive cannot travel out of the switching section 32".

If the switching lever 58 is pivoted in the direction-of the arrow 59, the actuating member 56 is also pivoted in the direction of the arrow 60. The actuating pin 30 of the locomotive 11, located in the central position and abutting against the guide surface 62, is then displaced towards the left, so that the direction of travel of the locomotive is changed to the direction which allows the locomotive to travel upwardly (FIG. 10) out of the switching section 132". I

When the locomotive arrives at the switching section 132', its actuating pin 30, directed towards the left, comes into abutment against the guide surface 53 and is deflected into the right hand position by way of the central position. Thus, the motor of the locomotive 11 is reversed, and the locomotive travels back again, i.e., from the top to the bottom in FIG. 10. The guide surface 54 of the switching section 132' ensures that a locomotive, which is pushed manually into the switching section with its switching lever in the central position, is switched into the direction corresponding to the direction of the arrow of the flat member 64.

Thus, it may be seen that the switching section 132 is a station which always ensures change over or passage in the direction of its arrow, irrespective of the side from which the locomotive is coming and irrespective of the direction of travel (forward or reverse) in which it enters, while the switching section 132", when in its position normally assumed, stops the locomotive and initiates departure in the predetermined direction by actuating the switching lever 58.

The described switching sections are particularly simple to manufacture and to operate and which provide numerous possibilities. For example, the switching section 132" may be inserted at a terminal railway station where the train automatically stops and then departs again in the opposite direction when desired. This switching section also forms an automatic buffer," so that the locomotive is prevented from leaving a nonclosed section of rail. It will also be seen that the same function may be performed in the opposite direction of travel merely by reversing the member forming the switching section 132'.
