Abstract

Composable track sections have two smooth driving surfaces (41, 42) and a central toothed rail (43) with two toothings (44, 45) which are spaced apart from one another in the transverse direction of the track section and perpendicular to the driving surfaces (41, 42). A driven chassis (4) has wheels (16) with smooth running surfaces. On its underside, the chassis (4) is provided with guide walls (21, 22) which face each other in pairs and which abut the toothings (44, 45) on both sides of the rack (43). The chassis (4) is provided with a drive motor, the drive axis (27) of which is perpendicular to the driving surfaces (41, 42) and is laterally displaced relative to the center of the distance of the guide walls (21, 22) which are opposed in pairs. A drive gear (28) attached to the drive axis is therefore only in engagement with one of the two toothings (44, 45). This cogwheel toy train has a high level of stability even when the road is laid with tight curves and steep gradients.

Description

The present invention relates to a toy rack railway according to the preamble of claim 1.

Known toy cogwheel railways, which are intended to overcome the lack of static friction of the drive wheels on steep gradients of the roadway, are essentially true-to-life replicas of actually existing cogwheel railways on a smaller scale. Their lanes accordingly have a toothed rack arranged centrally between two rails, into which at least one gearwheel driven by an electric motor of the locomotive engages. Although several systems, known under the names "System Riggenbach", "System Abt", "System Strub" and "System Locher", have been implemented in the actually existing rack and pinion tracks, known toy model rack and pinion tracks have both the racks for reasons of simple manufacture as well as the traction vehicle racks with open top teeth, for example according to the "Strub system".

The known model cogwheel railways understandably show the disadvantages of high manufacturing costs and limited robustness because of their required realistic model character. They are therefore not suitable for satisfying the play instinct of children of small age who have a differentiated techni There is a lack of understanding, of course, but there is still a need to let vehicles run independently on roads that are laid arbitrarily and unprofessionally, with steep gradients and tight curves. In addition, the known model cogwheel railways have the defect that also exists with the real cogwheel railways that the maximum possible gradient of the roadway is relatively small, in particular when curves are present. Only a relatively high weight of the locomotive and a relatively low trailer load or impact load can prevent the locomotive from "rising" from the rack. In addition, push operation is also possible in a very limited manner in the known model gear wheel railways because the pushed cars are pushed out of the road, particularly in curves, on steep inclines.

As such, the prior art also includes toys with other designs of a gear drive for a vehicle, which, however, is not part of a gear train.

From US Pat. No. 4,547,710 a movable toy is known which contains a horizontal, essentially smooth roadway on a carrier and a driven vehicle which represents the shape of a fantasy animal figure. The roadway has the shape of an approximate oval with two parallel roadway sections and two arcuate end connectors. Over its entire length, this roadway is provided on its inner edge with a toothing perpendicular to the driving surface of the roadway, with which a gearwheel of the vehicle, which can be driven by a battery-powered electric motor, engages stands. The vehicle extends over the two parallel lanes. When the electric motor is activated, the vehicle moves in one direction along the two lanes in order to turn 180 ° in the subsequent arcuate end connector and to drive on the lanes in the opposite direction. To guide the vehicle on the carrier, the vehicle is provided with a sliding shoe which is guided in a recess in the carriageway and between the toothing and an outer edge of the carriageway.

A toy similar in terms of locomotion of a vehicle is known from French patent 517.106. This toy also has on a carrier a closed, approximately oval road with a toothing perpendicular to the driving surface of the road at the inner edge of the driving surface. The vehicle, which rotates along this lane and is provided with a drive motor and a drive gearwheel engaging in the toothing mentioned, is also designed to move two aircraft models attached to the booms of the vehicle in a plane perpendicular to the lane of the girder raised above the ground to rotate.

In contrast, the present invention has the task of creating a toy rack railway of the type mentioned, which, while maintaining extensive model fidelity with a practically arbitrarily laid road in three dimensions, allows trouble-free operation even with high tensile and impact loads, without the need for specialist knowledge of the user.

According to the invention, the toy rack railway of the type mentioned has the features stated in the characterizing part of patent claim 1.

The invention also relates to a roadway and to a traction vehicle for a toy cogwheel train according to claim 1. The roadway according to the invention and the traction vehicle according to the invention are defined in claims 26 and 27, respectively.

The fact that, in the toy cogwheel train according to the invention, the guidance of the traction vehicle and also the guidance of further vehicles coupled to the traction vehicle takes place by means of the toothed member arranged on the roadway, results in a very high stability of the vehicle or vehicles on the roadway, whereby " Derailments "in tight bends and changeable, winding gradients can be practically excluded even at high driving speeds. The lateral toothing of the toothed member, which is arranged perpendicular to the driving surface of the carriageway, enables steep gradients to be overcome without the risk of the drive gear of the locomotive jumping out of this toothing. The one-sided engagement of the drive gear in the toothing of the toothed member allows the locomotive to be easily placed on the road. A roadway consisting of several linked roadway sections with gradients and curves can therefore be laid practically as desired and without knowledge of professional rules, without this resulting in a smooth operation Driving on the road would be questioned. In addition, there is a further advantage that the arrangement according to the invention of coupling devices between the locomotive and possibly other non-driven vehicles connected to the latter largely prevents the vehicles from being pushed out of the carriageway, even on steep gradients with curves, by the use of the Locomotive force is applied to each vehicle at a point as close as possible to the driving surface of the road and close to the center of gravity of the vehicle in question or the chassis of the vehicle.

1 to 8 an exemplary embodiment of the toy rack railway according to the invention is shown, with FIGS. 1 to 3 in side view, top view and bottom view of a train built from building blocks in the manner of a railcar train and FIGS. 4 to 8 various associated ones Show road sections.

1 to 3, the train shown has three cars, namely a head or control car 1, an intermediate car 2 and a trailer 3. The head car 1 is connected to the intermediate car 2 via a chassis 4 coupled on both sides, and the intermediate car 2 with the trailer 3 via a coupling on both sides Chassis 5 connected. The head coach 1 and the end coach 3 are also provided in their outer end regions with a bogie 6 and 7, respectively. 1 to 3, the outer linings of the carriages 1 to 3 and the chassis 4 and 5 are not shown, with the exception of the head carriage 1, in which a suitable carriage lining 8 composed of individual components is arranged. Such car trims, such as car bodies, doors, windows etc., are preferably assembled from individual components of a toy building system in the present exemplary embodiment and can of course be designed in any way without influencing the functioning of the present toy rack railway, which is still operated below. For the construction of such car panels, each car 1 to 3 has a platform serving as a car chassis 9, 10 and 11, via which platform the cars 1, 2 and 3 are also coupled to the chassis 4 and 5, as will be explained later. To accommodate additional components, the platforms 9, 10 and 11 are provided with coupling pins 12 in a manner known per se (FIG. 2). On their underside, the platforms 9, 10 and 11 are designed as hollow bodies which are reinforced by struts 13 (FIG. 3).

The chassis 4 and 5 and the bogies 6 and 7 are in the present embodiment, apart from Wheel axles and coupling or fastening elements, made in one piece from a plastic. According to FIG. 3, the two bogies 6 and 7 have an essentially hollow underside, which has molded-on bearing parts 14 for receiving rotatable wheel axles 15, each of which is provided with two loosely pressed-on rotatable wheels 16 with a smooth running surface. Furthermore, the bogies 6 and 7 have walls 17 and 18 which face each other in pairs and extend essentially in the longitudinal direction. As will be explained below, these walls 17 and 18 serve as guide walls of the bogies 6, 7 on a track provided with a toothed rack, the toothed rack coming to rest in the space between two opposing walls 17 and 18 when the train shown is on the roadway is put. On its upper side, each bogie 6, 7 is provided with a pivot pin 19 (FIG. 1) which is captively inserted into a hole 20 (FIG. 2) in the corresponding platform 9 or 11. Further details will be explained later with reference to FIGS. 16 and 17.

The biaxial undercarriage 5, which is a drive-free undercarriage, is designed on its underside according to FIG. 3 similarly to the bogies 6 and 7. It accordingly also has the integrally formed bearing parts 14, in which the parts with the wheels 16 provided wheel axles 15 are added. In addition, opposite guide walls 21 and 22 are provided in pairs on the underside. On the upper side, the chassis 5 is provided on both sides with an attached, pivotable coupling bracket 23 or 24, which is pivotable about lateral pin 25. The coupling brackets 23 and 24 are provided to releasably receive corresponding coupling elements at the adjacent ends of the platforms 10 and 11, respectively. This coupling device will be explained later with reference to FIGS. 12 to 15 and 19 to 21. On its upper side, the chassis 5 is also provided with a few coupling pins 12 which, like the platforms 9, 10 and 11, permit the attachment of structures such as cladding.

The chassis 4, as far as its underside is concerned (FIG. 3), is basically of the same design as the chassis 5 and accordingly has the same clamping tabs 14, wheel axles 15, wheels 16 and guide walls 21 and 22, respectively. However, since the chassis 4 is a driven chassis, an essentially cylindrical electric motor 26 is fastened in a vertical position on its upper side (FIGS. 1, 2). The electric motor 26 has a likewise vertical drive axis 27 (FIG. 3) which carries a gear wheel 28. The gear 28 is accordingly on the underside of the chassis 4 in the area of a guide walls 22, with its axis 27 lying to the side of the longitudinal center line of the chassis 4. As will subsequently be explained, the gearwheel 28, which is driven by the electric motor 26, preferably via a gear built into the electric motor, is intended to come into engagement with a side toothing of a toothed rack which is toothed on both sides and which is arranged centrally on a carriageway, in order to engage the chassis 4 and thus to move the entire train of FIGS. 1 to 3 along the roadway when the electric motor 26 is excited.

The electric motor 26 is fed via a plug 29 (FIG. 1) designed as a module and a feed cable 30 through a battery box 31 arranged on the head carriage 1. To control the electric motor 26, a slide 32 is located in the chassis 4 near the underside of the electric motor 26 arranged. The slide 32 is provided with switching contacts and can be brought from the illustrated "off" position (motor separated from the battery) by pressing in one or the other transverse direction into a circuit for forward or backward travel of the chassis 4 or the train . The slide 32 protrudes laterally beyond the chassis 4 and has bevelled surfaces at the ends. This allows actuating elements such as pins and the like to be arranged on the roadway, which act on the slider 32 the passage of the train and thus cause a stop or a change of direction of the train. It will be appreciated that it is also possible to provide a remote control, for example an infrared remote control, in order to control the electric motor 26 continuously and with respect to the direction of rotation. The carriages of the present train, in particular the head carriage 1, have sufficient space to accommodate the necessary receiving and switching elements.

Like the chassis 5, the chassis 4 is provided with two coupling brackets 23 and 24 mounted in lateral pins 25 in order to releasably connect the chassis 4 to the platform 9 of the head carriage 1 and to the platform 10 of the intermediate carriage 2. Furthermore, the electric motor 26 is also provided with a few coupling pins 12 for attaching covers or the like.

The toy rack railway according to the invention also comprises a track with a toothed member with which the gear of the electric motor of the locomotive engages. 4 to 8, preferred embodiments of straight and curved road sections are shown.

The straight track section shown in perspective in FIG. 4 and in bottom view in FIG. 5 can itself understandably have any, but preferably standardized, length. The track section has two smooth driving surfaces 41 and 42, which are separated in the longitudinal direction of the track section by a centrally located raised rack 43. The toothed rack 43 has a toothing 44 and 45, which is perpendicular to the driving surfaces 41 and 42 on both sides. To connect this track section with further, adjacent track sections, the track section in its end regions is provided on both sides with two coupling pins 46 formed in lateral recesses. A connecting plate 47, the rear side of which can be plugged onto the coupling pin 46 in FIG. 8, is provided with clamping pin 48, so that, as indicated in FIG be clamped connected.

It can be seen from FIG. 5 that the underside of the track section of FIG. 4 forms a cavity reinforced by struts 49. A box-shaped cavity 50 is also formed at each end of the road section. The purpose of this is to be able to plug the roadway piece onto a base or building plate, which is provided with coupling pins arranged according to a certain grid.

From FIG. 4 it can also be seen that the two end faces of the straight track section are each provided with a projection 51 and a corresponding depression 52. This design of the end faces causes a fixation of two lane pieces lined up in the transverse direction, so that the tabs 47 (FIG. 8) are only subjected to tension. In addition, the projections 51 and depressions 52 are also provided as coding elements in order to prevent the stringing together and connecting of certain pieces of roadway that do not match, which will be explained below.

In Fig. 6 is a plan view of a curved, extending over an angular range of 90 ° piece of roadway, which in turn has two smooth road surfaces 53 and 54, which are separated by a central, curved toothed rail 55, which has side teeth 56 and 57. In addition, this curved track section is provided in its end regions with lateral coupling pins 46 and on the end faces with the projections 51 and depressions 52. As can be seen from FIG. 7, the underside of the curved lane section of FIG. 6 is likewise designed analogously to that of the straight lane section of FIGS. 4 and 5 and has, in particular in the end regions, the box-shaped cavity 50 for plugging the track section onto the coupling pin of a base plate.

In this connection it should be noted that it is of course impossible to arrange a circular arc piece in a rectangular, in particular square, grid in such a way that end points of the circular arc piece match exactly with grid points, unless the circular arc piece extends over 90 °. In order to bring curved ends of the lane sections exactly into line with the grid points of a base plate or with coupling pins arranged in these grid points so that the curved road sections can be plugged onto the base plate without any constraint, it has already been proposed that each curved road section be made from a shorter straight line Section and a longer arcuate section to assemble (see. CH-PS .... Patent Application No. 7981/86).

6 is made use of this teaching. The 90 ° lane section shown in FIG. 6 is to be regarded as the composition of two 45 ° lane sections which are separated along the radial 45 ° line 58. Each of these 45 ° track sections is therefore composed of an arcuate section 59 or 60 and a much shorter straight section 61 and 62 together. 6 also shows the inner radius and the outer radius of the carriageway as well as the center radius of the toothed rail 55 of the arcuate sections 59 and 60 of the carriageway section, all of which emanate from a displaced center 63.

Instead of just a one-piece 90 ° lane section according to FIG. 6, it is of course also possible to provide and use 45 ° lane sections which, as mentioned, result from the 90 ° lane section of FIG. 6 by separation along the radial line 58. Such 45 ° track sections are of course provided at both ends with coupling pins 46 for connection to an adjacent, straight or curved track section. Since the 45 ° lane sections created by such a division, i.e. a lane section with sections 59 and 61 and a lane section with sections 60 and 62 are not identical, they are coded at the 45 ° ends with a different coding by protrusions and depressions provided, as indicated in Fig. 6 at the radial line 58.

Not shown are straight and curved lane sections provided with a toothed rail, which are suitable for forming a lane with gradients. In this regard and with regard to the required dimensions of general roadways that are to be used together with a predetermined grid of a base plate, reference is made to the aforementioned CH patent.

9 to 11, the bottom views of the chassis 4 and 5 and the bogie 7 of FIG. 3 are shown again, but on a larger scale and with the rack 43 of the straight track section of FIG. 4. It can be seen that the Chassis 4 and 5 with their guide walls 21 and 22 and the bogie 7 with its guide walls 17 and 18 are guided along the rack 43. It can also be seen from FIG. 9 how the gear 28 of the electric motor engages on one side in the rack 43. The transverse force generated thereby is absorbed by the guide walls 21.

The bogie 5 already described with reference to FIGS. 1 to 3 is shown in perspective in FIG. 12. One associated coupling bracket 23 is shown in perspective in FIG. 13, in plan view in FIG. 14 and in a section in FIG. 15. The coupling bracket 23 has two angled arms 65 which are provided with a clamping slot 66 at their ends. With this clamping slot 66, each arm 65 of the coupling bracket 23 can be applied to one of the pins 25 formed laterally on the chassis 5, as shown in FIG. 1. In the central yoke part 67, the coupling bracket 23 has a slot 68, the upper and lower slot walls being provided with a small, groove-like recess 69 in the inner part of the slot 68.

The slot 68 of the coupling bracket 23 serves to receive a corresponding coupling tongue, which are attached to the ends of the platforms 9, 10 and 11. 18 to 21, the platform 10 of the intermediate car 1 (FIG. 1) is shown in detail, but on a larger scale. The platform 10 is provided with an integrally formed tongue 70 and 71 on each end face. At their outer ends, the two tongues 70, 71 each have an upper and lower locking button 72. When a tongue 70 or 71 is inserted into the slot 68 of the coupling bracket 23 (FIGS. 13 to 15), the locking buttons 72 push the upper and lower slot walls slightly apart and into the groove-like recesses 69 (FIGS. 14, 15), so that the tongue 70 or 71 is held in the slot 68, ie the platform 10 is coupled to the coupling bracket 23 and thus to the chassis 5. To decouple the platform 10 is simply pulled off the coupling bracket 23. The same coupling design is also present in the further coupling brackets 23, 24 and the ends of the platforms 9, 10, 11 of FIG. 1 to be coupled.

18 to 21 show that the tongue 70 at one end of the platform 10 of the intermediate carriage 2 has a different cross-sectional shape than the tongue 71 at the other end of the platform 10. The tongue 70 (FIG. 20) has a rectangular cross-section, while the cross-sectional shape of the tongue 71 (FIG. 21) is similar to that of a rhombus. The tongue 70 (rectangle) brings about a connection which is rigid with respect to the direction of rotation about the longitudinal axis of the platform 10 in the slot 68 of the coupling bracket 23, 24, since the tongue 70 lies against the upper and lower wall of the slot 68. The tongue 71 (rhombus), on the other hand, allows a slight swiveling back and forth in slot 68. If all of the carriages 1 to 3 of FIG. 1 are rigidly coupled via the chassis 4 and 5 in the direction of rotation mentioned, by designing all the tongues like the tongue 70 (FIG. 20), then there is the disadvantage that the carriages are very tight Take tight bends, especially those on slopes, off the road. If, on the other hand, only tongues according to tongue 71 (FIG. 21) are provided, the car may run roughly at any speed. It is therefore favorable to use both forms of tongues 70 and 71 in a mixed manner, which is readily possible because the slot 68 of the coupling bracket 23 can accommodate both tongues 70 and 71.

In Fig. 12, the non-powered chassis 5 is shown. However, the driven undercarriage 4 coincides with this, except for the applied electric motor 26 (FIG. 1), so that the design and arrangement of the coupling bracket 23, 24 in the driven undercarriage 4 in FIG. 1 is the same as in the traveling undercarriage 5.

• 1) Die genannten Angriffspunkte sollen in der Höhenrichtung (senkrechten Richtung) bezüglich der Fahr­bahn möglichst nahe denjenigen Stellen liegen, die an der Fahrbahn und am Fahrgestell an einer Krafteinwir­kung für den Vorschub des Fahrgestells und der mit die­sem gekuppelten Wagen beteiligt sind. Diese Stellen sind demnach einerseits beim angetriebenen Fahrgestell die Eingriffstelle des Zahnrades des Antriebsmotors in die Verzahnung des verzahnten Organs, und andererseits bei allen Fahrgestellen die Auflagepunkte ihrer Räder auf den glatten Fahrflächen der Fahrbahn. Daraus ergibt sich die erste Vorschrift, dass die Kupplungsbügel 23, 24 an die Fahrgestelle 4, 5 so tief als möglich, d.h. auf dem Niveau der Zahnstange 43 (Fig. 4) und möglichst nahe den Fahrflächen 41, 42 (Fig. 4) angelenkt sein sollen. Aus den Fig. 1 und 12 ergibt sich, dass die bezüglich der Fahrbahn tiefe Lage der seitlichen Zapfen 25 der Fahr­gestelle 4, 5 dieser Vorschrift nachkommt.
• 2) Die genannten Angriffspunkte sollen darüber­hinaus benachbart, das heisst, so nahe wie konstruktiv möglich, zu einer Ebene liegen, welche zur Längsrichtung des Fahrgestells senkrecht ist und den Schwerpunkt des Fahrgestells enthält. Bei den in der Fig. 1 dargestell­ten Fahrgestellen 4 und 5 liegt diese Ebene in der Mitte der Fahrgestelle quer zur Längsrichtung des dar­gestellten Zuges. Somit sind die seitlichen Zapfen 25 der Fahrgestelle 4, 5 für die Kupplungsbügel 23 und 24 sehr nahe diesen Fahrgestellmitten ausgebildet. Die Kupplungsbügel 23, 24 weisen, in eher unüblicher Art, entsprechend lange und geneigte Arme 65 (Fig. 15) auf, damit gemäss Fig. 1 die Kupplung der Fahrgestelle 4 und 5 mit den Plattformen 9, 10 bzw. 10, 11 der benachbarten Fahrzeuge 1, 2 bzw. 2, 3 an den Enden der Fahrgestelle möglich ist.

The arrangement of the coupling brackets 23, 24 on the chassis 4, 5, which can be seen in particular from FIG. 1 and from FIGS. 12 to 15, represents an embodiment of the present toy cogwheel train according to the invention, which is particularly advantageous and enables the track to be used to lay unusually steep inclines, also in connection with very tight bends, without there being a risk that the locomotive and other vehicles coupled to it would lift off the road and thus "derail" or "crash". The measure according to the invention consists in the fact that the points of application of the power transmission from a chassis to a vehicle coupled to this chassis or to its platform serving as the vehicle chassis are provided at locations on the chassis itself which have specific requirements with regard to the roadway or the chassis in accordance with the design Fully meet the possibilities at least approximately. These requests are the following :

• 1) The specified points of attack should be as close as possible to those points in the vertical direction (vertical direction) with respect to the carriageway that are involved in the force on the carriageway and on the chassis for the advancement of the chassis and the cars coupled to it. These points are therefore on the one hand the point of engagement of the gear of the drive motor in the toothing of the toothed member in the driven chassis, and on the other hand the support points of their wheels on the smooth surfaces of the carriageway on all chassis. This results in the first regulation that the coupling brackets 23, 24 are articulated to the chassis 4, 5 as deep as possible, ie at the level of the rack 43 (FIG. 4) and as close as possible to the driving surfaces 41, 42 (FIG. 4) should be. 1 and 12 show that the position of the lateral pins 25 of the chassis 4, 5, which is deep with respect to the roadway, complies with this regulation.
• 2) The points of attack mentioned should also be adjacent, that is, as close as possible to the design, to a plane that is perpendicular to the longitudinal direction of the chassis and the center of gravity of the Includes chassis. In the chassis 4 and 5 shown in FIG. 1, this plane lies in the middle of the chassis transverse to the longitudinal direction of the train shown. Thus, the side pins 25 of the chassis 4, 5 for the coupling bracket 23 and 24 are formed very close to these chassis centers. The coupling brackets 23, 24 have, in a rather unusual way, correspondingly long and inclined arms 65 (FIG. 15), so that, according to FIG. 1, the coupling of the chassis 4 and 5 with the platforms 9, 10 and 10, 11 of the neighboring ones Vehicles 1, 2 or 2, 3 at the ends of the chassis is possible.

The fulfillment of the two requirements mentioned above by the articulation of the coupling bracket 23, 24 to the chassis 4, 5 shown in FIG. 1 has the effect that all forces which are transmitted from the chassis 4, 5 to the coupled platforms 9, 10, 11 are transmitted , have a major, predominant component that is parallel to the road. The vertical force component, that is, the upward force component, is considerably smaller. This means that only a negligibly small moment is generated, which strives to move the chassis and the vehicles coupled to them upwards perpendicular to the road to take off this. In addition, since the lateral toothing 44 or 45 (FIG. 4) or 56, 57 (FIG. 6) prevents the drive gear 28 (FIG. 9), which is engaged with the toothing, from climbing out of the toothing, the present toothed wheel path has one very high stability, even if the road is laid on steep inclines and tight bends without suitable pillars (ie "free hanging"). A slope limit is essentially only reached when the vertical plane passing through the center of gravity of a chassis intersects the contact points of the wheels on the affected wheel axle on the road. This corresponds to an incline of the road of significantly more than 100% in the present cog railway. In addition, with the cogwheel train at hand, the advantages mentioned exist regardless of whether the traction vehicle pulls or pushes other, coupled vehicles.

In Fig. 16 the bogie 6 or 7 (Fig. 1, 3) is shown in perspective; 17 is a perspective view of a rotating element 19 for mounting the bogie 6, 7 in the platforms 9 and 11 (FIGS. 1, 3). The rotating element 19 has a cylindrical pin element 75 which is attached to a support bracket 76. The support bracket 76 has two arms 77, which with a clamp slots 78 are provided. The arms 77 are inserted through slot openings 79 of the bogie 6, 7 and then, as can be seen in FIG. 3, clamped onto retaining webs 80 of the bogie 6, 7. The pin element 75 has an edge bead 81 which is elastic in that the pin element 75 is provided with two longitudinal slots 82. The rotary element 19 with the attached bogie 6, 7 can therefore be inserted in a simple manner into the hole 20 (FIG. 2) provided in the platform 9 or 11, but it cannot be lost.

FIG. 22 shows an alternative guidance of the driven chassis 4 to the embodiment according to FIG. 9. The guidance of the chassis and the absorption of the pressure exerted by the drive gear 28 via the rack 43 is taken over by two loosely rotatable toothed rollers 83. Here, the friction of the rack 43 on the chassis 4 is somewhat less than when it bears against the guide walls 21 (FIG. 9). However, there is the disadvantage that the chassis 4 can no longer be easily placed on the roadway because of the gear wheels 28 and 83 on both sides.

1 to 3, a train consisting of several carriages 1, 2, 3 is shown for example. It It is understandable that other, practically arbitrary combinations of chassis 4, 5 with coupled vehicles or platforms using end bogies 6, 7 are also possible. In particular, the locomotive can be a single locomotive which would consist of a driven chassis 4 and the coupled car 1 with bogie 6, with reference to FIG. 1, further car linings (not shown) being arranged and the coupling bracket 24 at the outer end of the chassis 4 could be omitted.

Another embodiment of the locomotive according to the invention is explained with reference to FIGS. 23 to 34. 23, this exemplary embodiment relates to an electric locomotive which, as essential components, has a platform 85, a car body 86 built thereon with components, two chassis 87 and 88 and a coupling device 89 each connected to the chassis 87, 88, wherein one chassis 87 is driven and the other chassis 88 is a moving chassis. According to the invention, this locomotive is intended for a carriageway which has a smooth driving surface 90 and a toothed rack 91 which is arranged in the center of the carriageway and has toothing on both sides, as is shown, for example, in FIG. 4 as a carriageway piece. The Embodiment of FIG. 23 is characterized in that not only the structure 86 of the platform 85 is composed of individual components, but also that the chassis 87 and 88 are formed by stacking several components, as will be explained below.

24 and 25 show the two chassis 87 and 88 of FIG. 23 in a side view and on a larger scale, the side wheel cover plates 92 and the wheels 96 (FIG. 23) being shown on the view side in FIGS. 24 and 25 are omitted.

24, the driven chassis 87 is composed of the following components:
- A guide and basic component 93, which extends over the entire length of the chassis 87, and which is designed on the one hand as a base for the construction of further components and on the other hand as a sliding guide element of the chassis 87 along the rack 91;
- Two bearing plates 94 mounted on the guide component 93, each of which has openings for receiving a wheel axle 95, on which two running wheels 96 with smooth running surfaces are arranged for the smooth running surfaces 90 of the carriageway located on both sides of the rack 91;
- A drive unit 97 plugged onto the bearing plates 94, which has two longitudinal plate parts 98, two protruding side plate parts 99 (only one of these visible in FIG. 24) and an electric motor 100, the drive axis of which is provided with the drive gear 28 already mentioned above, which is provided with the a toothing of the rack 91 is engaged;
- Two holding brackets 101, which are attached to the drive unit 97 and the guide component 93 and thus hold the guide component 93, the bearing plates 94 and the drive unit 97 together as a structural unit;
a connecting bracket 102, which is articulated to the guide component 93 and is provided for rotatably connecting the chassis 87 to the platform 85 of the locomotive shown in FIG. 23; and
23, the coupling device 89 already mentioned with reference to FIG. 23, which contains a coupling bracket 103 which is likewise articulated to the guide component 93 and which is designed to couple the chassis 87 and thus the locomotive shown in FIG. 23 to another vehicle.

25, the non-driven undercarriage 88 is composed in a similar manner to the driven undercarriage 87 in FIG. 24, specifically from the following components:
a guide and basic component 104, which performs the same assembly and sliding guide functions as the corresponding element 93 of FIG. 24;
two bearing plates 94 which are plugged onto the guide component 104 and which are provided in accordance with the identical bearing plates 94 of FIG. 24 for receiving the wheel axles 95 provided with wheels 96;
two holding brackets 105 which hold the guide component 104 and the bearing plates 94 together;
a central pivot element 106 which is plugged onto the guide component 104 and can be rotatably arranged in the platform 85 (FIG. 23) of the locomotive; and
the same coupling device 89 of FIG. 24, which is articulated on the guide component 104 and comprises the coupling bracket 103.

The individual components of the chassis 87 and 88 can be seen more clearly from FIGS. 26, 27 and 28, 29 and also from FIGS. 30 to 34.

FIG. 26 shows the driven chassis 87 including the wheel cover plate 92 (FIG. 23) in a perspective view. The individual components are shown in an exploded perspective view in FIG. 27, but the wheels 96 (FIG. 26) and their wheel axles have been omitted.

As already mentioned with reference to FIG. 24, the chassis 87 has the elongated guide and basic component 93, which is provided on its upper side with a number of the coupling pins 12 belonging to the system of the present components. On its underside, the guide component 93 is shown in FIG. 30 formed, opposite sliding guide walls 107 and 108, the space 109 is intended to receive the rack 91 (Fig. 23, 24), as has already been described with reference to the embodiment of FIGS. 1 to 3. The guide component 93 is provided on its one long side with a recess 110 which serves to receive the drive gear 28 (FIG. 24). Both long sides are also provided with four molded bearing journals 111a, 111b, 111c and 111d and with two stops 112 designed as molded projections.

As already shown in FIG. 24, the connecting bracket 102 and the coupling bracket 103 of the coupling device 89 are articulated to the guide component 93. For this purpose, the connecting bracket 102 has two arms 113, which are provided at their ends with a clamping slot 114, such that the arms 113 can be plugged onto the inner bearing journals 111c. The yoke part of the connecting bracket 102 has a slot-like opening 115, in which a pin 116 is formed. As will be explained in more detail with reference to FIG. 34, the connecting bracket 102 serves to pivotally connect the chassis 87 to the platform 85 of the locomotive according to FIG. 23. A possible swivel in the height direction Downward movement of the connecting bracket 102 is limited by the fact that its arms 113 abut the adjacent projections 112 of the guide element 93 (FIG. 24).

The coupling bracket 103 of the coupling device 89 is similar to the connecting bracket 102 and also has two arms 117 and 118, each of which is provided with a hole 119 in its end regions. Thus, as can also be seen from FIG. 24, the coupling bracket 103 can be plugged onto the outer bearing journals 111a, a downward pivoting movement of the coupling bracket 103 being restricted by the fact that extensions 120 of the arms 117, 118 on the adjacent projections 112 of the guide component 93 (Fig. 24).

The yoke part of the coupling bracket 103 also has a slot-like opening 121, in which a pin 122 is formed. The opening 121 and the pin 122 serve to receive a clamping tab 123 of a further two-armed bracket 124, the two arms 125 of which each have a hole 126. A magnet holder 127, which comprises a permanent magnet 128, is provided with two bearing pins 129 which fit into the holes 126. In the assembled state (FIG. 24), the magnet holder 127 can therefore rotate between the arms 125 of the bracket 124. In a manner known per se, therefore, the permanent magnets 128 of similar coupling devices 89 of two abutting vehicles can rotate in such a way that the north pole of one magnet faces the south pole of the other magnet and then a magnetic coupling of the two vehicles takes place.

According to FIG. 27, two bearing plates 94 are fitted onto the coupling pins 12 of the guide component 93, each of which has two clamping openings 131 for receiving a wheel axle (not shown). The underside of one of these bearing plates 94 is shown in FIG. 31. In addition to a groove-shaped recess 132 for said wheel axle, the otherwise hollow underside of the bearing plate 94 has, in a manner known per se, a central, short and integrally formed tube piece 133 which, together with the lateral inner surfaces of the hollow underside, serves as the coupling pin 12 of the guide component 93 to clamp. The bearing plates 94 are also provided on their upper side with coupling pins 12. It can also be seen from FIG. 26 that the wheels 96 placed on the wheel axles 95 lie laterally outside the connecting bracket 102 and the coupling bracket 103.

The drive unit 97 is placed on the bearing plates 94 as a further component. As already mentioned with reference to FIG. 24, this has two longitudinal plate parts 98, two side plate parts 99 and the upright electric motor 100. The top of the longitudinal plate parts 98 and the side plate parts 99 are in turn provided with coupling pins 12. 32, the undersides of the longitudinal plate parts 98 are of the same design as those of the bearing plates 94 (FIG. 31), apart from the means for mounting the wheel axle. The drive gear 28 of the electric motor 100 protrudes between the side plate parts 99 and comes to rest in the recess 110 of the guide component 93 (FIG. 30). Furthermore, a pin 134 which is movable in its longitudinal direction is arranged in each side plate part 99 (cf. also FIGS. 23, 24 and 26) and can act on an inner switching device (not shown) for the feed circuit of the electric motor 100. It is thus possible to arrange protrusions on the carriageway which actuate the pins 134 when the locomotive passes through, as a result of which a stop or a reversal of the direction of travel of the locomotive is effected via the feed circuit of the electric motor 100.

In order to hold the listed components, namely the guide component 93, the bearing plates 94 and the drive unit 97 together, the two retaining brackets 101 (FIG. 24) are present, which are plugged onto corresponding coupling pins 12 of the longitudinal plate parts 98 of the drive unit 97, and which with the their arms 135 provided clamping slots 136 are snapped into the remaining journals 111b and 111d of the guide component 93.

Finally, an outer wheel cover plate 92 is also provided on both sides, which is plugged onto the coupling pin 12 of the side plate parts 99 of the drive unit 97 and has only a purely decorative function.

The structure of the non-driven bogie of FIGS. 23 and 25 will now be explained in more detail with reference to FIGS. 28 and 29, FIG. 28 showing a perspective view of the bogie complete including the wheel cover plates 92. The individual components are shown in an exploded perspective view in FIG. 29, but the wheels 96 (FIG. 28) and their wheel axles 95 (FIG. 25) have been omitted. Since individual components are the same as in the driven chassis 87 according to FIGS. 26 and 27, these are given the same details and are no longer described in detail.

The bogie 88 has the elongated guide and basic component 104 already shown in FIG. 25, which essentially, also with regard to the underside shown in FIG. 33, corresponds to the guide element 93 of the driven chassis 87 of FIGS. 26, 27. The difference is that a recess 110 (FIG. 27) for receiving a drive gear wheel is not present, and that both longitudinal side walls are instead provided with a further bearing journal 111e.

25, 28 and 29 can be seen, a coupling device 89, comprising the coupling bracket 103, the further bracket 124 and the rotatably mounted magnet holder 127 with the permanent magnet 128, on the guide component 104 via the holes 119 of the coupling bracket 103 and Hinge pin 111d articulated, as has already been explained for the driven chassis 87 with reference to FIGS. 26 and 27.

Two bearing plates 94 for the rotation axes 95 (FIG. 25) provided with the wheels 96 are in turn attached to the guide component 104, the bearing plates 94 being identical to those of FIGS. 27 and 31.

In order to hold the bearing plates 94 on the guide component 104, two holding brackets, namely the holding brackets 105, are again present, which, with their ends provided with clamping slots 136, are engaged by arms 135 in the bearing journals 111a and 111c.

Instead of the drive unit 97 of FIGS. 26, 27, the bogie 88 according to FIGS. 28 and 29 is provided with a pivot arrangement 138. An unspecified base carries a pivot pin 139, which is provided with an upper edge bead 140 and has longitudinal slots 141 in the region of this edge bead. Furthermore, two downwardly directed tabs 142 are formed on the base (only one tab is visible in FIG. 29), the ends of which have a clamping slot 143. In addition, the base has lateral projections, each of which is provided with an upper coupling pin 12. The pivot pin arrangement 138 is pivotably fastened on the guide component 104 in that its tabs are snapped into the additional, central bearing pins 111e.

Finally, the decorative wheel cover plates 92 (FIG. 29) are plugged onto the side coupling pins 12 of the pivot pin arrangement 138.

The connection of the chassis 87 and 88 to the platform 85 of the locomotive (FIG. 23) is realized as follows.

According to FIG. 34, the platform 85 has, in addition to a number of coupling pins 12 for plugging on any cladding and also a battery box (not shown) for feeding the electric motor 100 (FIG. 23), an opening 145 through which the electric motor 100 located on the chassis 87 can be passed through. A tab 146 projecting into the opening 145 is formed on the platform 85 and is provided with a clamping slot 147 at its free end. To attach the chassis 87 to the platform 85, the motor 100 (FIG. 26) is guided through the opening 145. At the same time, the slot 115 of the connecting bracket 102 is brought onto the tab 146 until its clamping slot 147 engages in the pin 116 (FIG. 27) of the connecting bracket 102. The chassis 87 is thus pivotably arranged on the platform 85.

The platform 85 is provided with a central bore 148 for the rotary fastening of the bogie 88. In this hole, the radially elastic pivot pin 139 (Fig. 29) of the chassis 88 ge plugged. The pivot 139 and thus the entire chassis 88 are rotatably held on the platform 85 by the edge bead 140.

It can be seen in particular from FIGS. 24 and 25 that the force-transmitting elements, namely the connecting bracket 102 and the coupling devices 89 in the bearing journals 111, 111a to 111d, are also very close to the driving surfaces 90 and close to the center of gravity in this embodiment of the gear train according to the invention. Transverse plane are articulated on the chassis 87 and 88, so that the stability of the rack railway on the road is guaranteed in this embodiment up to the natural tilt limit.

The toy rack and pinion railway according to the invention can not only be designed, as previously described, in the sense of a railway with a roadway that is level on the floor or in ramps, but can also have the form of a monorail conveyor. 35 shows an example of such a monorail in a view transverse to the longitudinal direction of the carriageway, partly in section.

In this embodiment, the roadway consists of roadway sections 150 that can be arranged in a row with one box-shaped profile that is open on its lower side. Since this roadway should be located above the floor 151 (suspension track), the roadway sections are supported at certain longitudinal distances by pillars 152, which in the sense of the present component system can advantageously be plugged onto the roadway sections 150 in a manner not shown, in order to determine the roadway sections 150 in a certain manner Support height from the floor 151.

The profile of the roadway sections 150 accordingly has two legs 154 delimiting a lower opening 153, a yoke 155 opposite the opening 153 and two webs 156 connecting the yoke 155 to the legs 154. The inner surfaces of the legs 154 form driving surfaces for the wheels 96 of a vehicle 157. The inner side of the yoke 155 is provided with a toothed rack 158.

In the exemplary embodiment shown, the vehicle 157 designed as a traction vehicle has a driven chassis 159, which is constructed essentially the same as the driven chassis 87 of FIGS. 26 and 17, but is adapted to the suspension construction in deviation from this and has a different coupling device. Thus, the chassis 159 has the leadership and 27, the two bearing plates 94, in which the wheel axles with the wheels 96 are mounted, the drive unit 97 with the electric motor 100 and the two side plate parts 99, in which switching pins 134 for the electric motor 100 are arranged, and the two retaining brackets 101. Furthermore, a coupling device with arms 65 of the coupling bracket 67 (FIG. 13) is articulated to the guide component 93 and has the slot 68 for receiving the tongue 71 of the coupled platform of a carriage (FIGS. 18 to 21). The electric motor 100 also has a drive axis perpendicular to the inner surface of the yoke 155, which carries a drive gear, not shown, which is in engagement with one of the two toothings of the rack 158.

It can thus be seen that the monorail of FIG. 35 has the same function as that of the train of FIG. 1 or the locomotive of FIG. 23. Since the wheels 96 of the vehicle 157 are caught in the inside of the box-shaped profile of the road section 150, that is to say the distance between the inner surfaces of the legs 154 and the inner surface of the yoke 155 is only slightly larger than the diameter of the wheels 96, the road section 150 can also be vertical or be arranged obliquely to one with the corresponding to the chassis 159 car body Form elevator or inclined elevator. In order to be able to insert the vehicle 157 into the box-shaped profile of the roadway 150, the roadway must contain a specially designed roadway section at one or more points, in which the legs 154 can be removed or folded out.

With regard to the roadway, the invention is not restricted to the embodiments described so far and in particular shown in FIGS. 4 and 6. Rather, other arrangements of the driving surfaces and the toothed member are also included in the scope of the invention, as will be explained below with reference to FIGS. 36a to 36h. In each of these figures, a section of a roadway is shown in profile, the running surface or running surfaces being designated by arrows pointing vertically downward and the two side toothings of the toothed member being shown in the usual manner with double dashes.

• 36a shows the cross-sectional shape of the embodiment already described with reference to FIGS. 4 and 6 with two driving surfaces and a rack arranged in the center.
• 36b shows a corresponding embodiment in which the toothed organ is not a tooth rod raised above the running surfaces, but is designed as a groove with teeth on both sides.

• 36d accordingly shows the case of FIG. 36b with recessed driving surfaces.

• 36g and 36h show lanes with a toothed rack toothed on both sides and a toothed groove toothed on both sides, which allow the vehicles to be designed in the so-called "monorail" form (wheel axles with only a single wheel). In the embodiment according to FIG. 36g, the upper, smooth surface of the toothed rack forms the only driving surface, while in the embodiment of FIG. 36h, the toothing is formed by the smooth bottom ten groove is formed.

In all of the illustrated embodiments, in particular those which result in a small wheel distance of the wheels arranged on the same axis (FIGS. 36e, 36f), or that only require one wheel per wheel axis (FIGS. 36g, 36h), safe guidance is provided of the vehicle or its chassis thereby ensures that, according to the invention, each vehicle is equipped with sliding or rolling guide means which bear against the two toothings of the toothed member.

According to the previously described embodiments of the toy rack railway according to the invention, the vehicles or the bogies or bogies are provided with running wheels which roll on the smooth running surfaces. It has been shown that the vehicles or their bogies or bogies can also be provided with sliding surfaces for the running surfaces instead of with wheels. Although the frictional resistance becomes greater than the rolling resistance, it is not to such an extent that the use of battery-powered traction vehicles is no longer economical and therefore no longer sensible.

In the previously described exemplary embodiments of the toy rack railway according to the invention, a battery accommodated on one of the vehicles is provided as the source of supply for an electric motor, which battery can of course also consist of rechargeable battery elements. Furthermore, it has been described that 3-way control (stop, forward drive, reverse drive) of the electric motor can be achieved by means of action elements arranged by hand or on the roadway, or virtually any control of the electric motor by means of a remote control device known per se. The use of batteries as a power source is by no means uneconomical and therefore not unreasonable, since it has been shown that the rack and pinion railway according to the invention operates perfectly with commercially available batteries on a road with numerous inclines over a period of 6 to 25 hours of pure travel time until the batteries are exhausted can be.

However, there may also be a desire to create a battery-independent, continuously controllable supply of the electric motor of the present cogwheel train over its lane. An expedient embodiment of such a roadway is shown schematically in FIGS. 37 to 39.

FIG. 37 shows a track section according to FIG. 4, which is provided with three rows 161, 162 and 163 of point contacts 164 known per se. The point contacts protrude slightly above the two driving surfaces 165 and the upper surface 166 of the rack 167. In a likewise known manner, the two outer rows 161 and 162 of the point contacts 164 arranged in the driving surfaces 165 are electrically connected to one another, but are electrically isolated from the middle row 163 arranged in the rack 167.

Such point contacts 164 can be achieved in a simple manner by inserting and anchoring a corresponding metal strip 168 (FIG. 38) in a section of roadway formed with the required openings (slots).

The electrical connections between two mechanically interconnected track sections (see FIGS. 4 to 8) can also be achieved in a simple manner by arranging two resilient, electrically separate contact pieces 169 and 170 on the front side of each track section according to FIG which one with the outer rows 161 and 162 of contacts 164 and the other with the middle row 163 of contacts 164 is in electrical connection. since a mechanically firm connection of adjacent road sections is achieved by the connecting straps 47 (FIG. 8), there is also a perfect electrical connection of resilient contact pieces 169 and 170.
