Description

Track for model railways with track bedding

The invention relates to a track for model railways as described in the preamble of claim 1.

Track elements for model railroads usually consist of a ^'one- piece grate made of plastic injection molding, the shape of which corresponds to a track grate, the rails being connected to the sleepers by means of these one-piece extensions, which have the shape of holding plates with nails, and the rails which are the sleepers of the Cover the rust-connecting web parts. To connect the individual track elements to one another, the rails are provided at their ends with coupling pieces which enable the tracks to be connected by plugging them together. With the track elements, which consist of straight and curved track sections as well as switches and crossings, the desired track systems can then be constructed, which are usually attached to a plate in order to avoid undesired displacements.

In order to fulfill the model railroaders' wish for the most natural possible track structures, the manufacturers have developed tracks of the type specified at the beginning. In the known tracks, however, the track gratings are usually fixed and lead bend connected to the track bed simulating the superstructure, so that the tracks with track bedding are joined and laid like tracks without track bedding. The known tracks with track bedding only allow the intended installation in a track system, so that modifications in the construction and deviations from a given track plan are only possible to a limited extent. Since the individual track elements with track bedding can only be used in accordance with their intended purpose, without these changes being permitted, appropriate prefabricated versions must be used in the event of variations in the track layout or in the event of a subsequent conversion

Track elements are available, which restricts the model railroader in creating individual and modified track diagrams if he does not have a large number of different track elements available with and without track bedding.

It is therefore an object of the invention to provide a modular track bed system which allows conventional track elements, that is to say those without special bedding parts, to be laid in the usual manner and optionally to connect these track elements to bedding parts, the Bedding parts are adapted to, or adaptable to, the usual tracks and track elements, and repeated use of the bedding parts is also possible in track systems with other track patterns.

According to the invention, this object is achieved on a track of the generic type by the features specified in the characterizing part of patent claim 1. The model railroader has the option of laying conventional track elements with or without the bedding part according to the invention. A correspondingly shaped bedding profile can be assigned to each track element, which is either already preformed by the manufacturer or can be adapted to the respective track element by simply being cut by the model railroader. Through the intermediate Switching the bedding part between the track grate and the stiffening elements also achieves noise insulation of the driving noise.

The development according to claim 2 ensures that a torsionally rigid support and a simple height and side alignment of the track is possible.

The development according to claim 3 ensures that at least one strip of the strips arranged in pairs is so high that its lower edges are flush with the side edges of the bedding part in the side view.

An embodiment according to claim 4 is also advantageous, as a result of which undesired torsions and resulting derailments of the model railroad vehicles can be avoided.

The measure according to claim 5 ensures that a desired track alignment in the vertical and lateral directions can nevertheless be achieved with a limp, elastically deformable part.

The measure according to claim 6 makes it possible to compensate for production-related tolerance deviations between the bedding parts and the ladder-shaped parts. In addition, the bedding parts can also be curved, so that curved bedding pieces can also be easily produced with these bedding parts.

A further embodiment is expedient, as a result of which centering and alignment of the bedding parts to a desired bedding course predetermined by the strips is possible without additional measures. An embodiment according to claim 20 is advantageous, since the weakening lines guide the scissors to separate side parts of the bedding body.

A further development according to claim 21 is equally possible. By means of these coupling pieces, the bedding parts can then be connected to one another in a simple manner.

A further development according to claim 22 is also advantageous. This configuration enables a snap connection of the bedding parts stiffened by the ladder-shaped profiles.

In order to further improve the modularity and variability, an embodiment according to claim 23 is also possible. In the case of switches or curved sections or if required, these adapter pieces can be inserted in order to continuously connect the bedding parts to one another.

However, an embodiment according to claim 24 is also advantageous, since in this way a connection of the stiffeners can be easily established with any longitudinal configuration of the individual tracks.

But it is also a further development according to claim 25, whereby a coupling with the adapter pieces is possible even after the support device has been bent down.

An embodiment according to claim 26 is advantageous. As a result, the connection between individual support devices or track gratings or bedding parts can be made at any point and the formation of coupling parts and thus the production of track parts with different coupling parts is avoided . Another solution is described in claim 13. In spite of the omission of a continuous track grate, an exact positioning of the sleeper band or track grate in the bedding part can be achieved.

An embodiment according to claim 14 is expedient. Pins or nails can be passed through these aligned bores in order to connect the tracks embedded in the bedding parts to a mounting plate.

The arrangement of bowl-shaped holding parts according to claim 15 enables the bed and holding parts to be connected and disconnected quickly.

In the embodiment according to claim 16, the tracks can be detachably connected to their bedding bodies by the cover connections.

The adaptation of the bedding body to different track patterns is achieved in a simple manner by the measures according to patent claim 17.

An embodiment variant according to claim 18 is also advantageous. Corresponding cutouts enable an acute-angled connection of bedding parts, as is required, for example, following switches.

By means of the development according to claim 19, the side parts, for example the side parts simulating the slopes, can then be separated from the central part of the bedding bodies and can then be connected to the central part again by means of special side part profiles. In this way, cut bedding parts can be reused without sacrificing appearance. An embodiment according to claim 20 is advantageous, since the weakening lines guide the scissors to separate side parts of the bedding body.

An embodiment according to claim 26 is advantageous. As a result, the connection between individual support devices or track gratings or bedding parts can be made at any point, and the requirement for coupling parts and thus the production of track parts with different coupling parts is avoided . Another solution variant is described in patent claim 27, which, in addition to providing good protection against unwanted loosening in the longitudinal direction of the track, also enables exact height and lateral guidance in the transition region between the individual rails of the track when the bedding parts or track gratings abut one another.

Another embodiment is described in claim 28, as a result of which a precise alignment of the ends of the rails of adjacent track gratings can be achieved without any problems even when connecting center webs or longitudinal spars through sleeve parts.

However, an embodiment according to claim 29 is also possible, so that the model railroader no longer needs to subsequently edit the bedding in the area of switches or overhead line masts.

In the embodiment according to claim 30, a track structure that is exact in reality is also possible with multi-track track systems.

The further development according to claim 31 is advantageous, since with the assembly of the track grate a track geometry that is almost identical to reality and thus a better driving behavior of the model vehicles, in particular in track arches, can be achieved.

The further embodiment according to claim 32 has the result that the entire track structure can be easily simulated with the laying of the bedding parts. -10-

3-wire track system can be retrofitted and with the same parts for the normal two-wire track system and a 3-wire track system it can be found.

Due to the design according to claim 46, the choice of different bedding parts or central parts makes it possible to adapt the track system that can be produced according to the invention to the two-wire or three-wire system at any time.

Furthermore, an embodiment according to claim 47 is also possible, since the arrangement of additional power supply lines can be dispensed with and the risk of line interruptions is additionally reduced.

The measure according to claim 48 ensures that when the track system is assembled, the electrical line connection for an additionally arranged center conductor or the contact pins are simultaneously established.

Another embodiment variant is described in claim 49, whereby contacts provided with snap elements can be easily used for power supply, in particular in broken track sections or in the area of reversing loops, and for individual power supply along the track grating. In addition, the arrangement of monitoring organs, for example, track-occupied signaling systems or barrier systems or the like can be easily controlled via such monitoring organs arranged in the region of the rails of the track grate.

A further development according to claim 50 is also advantageous, since the necessary drives, monitoring and control devices for monitoring, controlling and actuating equipment parts of such track systems, for example of point machines and the like, are thereby directly incorporated into the invention. of the granules, it is possible to take into account the natural conditions and different colors that also occur with ballast.

An embodiment according to claim 40 is also advantageous, since in this way the granulate character is retained in any case even when the plastic material receiving the granulate is melted.

However, a further development according to claim 41 is also possible, whereby a secure hold of the granulate parts in the surface of the bedding parts is achieved and, on the other hand, a true-to-nature reproduction of the actual conditions can be achieved.

An embodiment according to claim 42 is advantageous, since electrical connections or additional fastening elements in the bedding part or the central part can subsequently be introduced in a simple manner at predefined locations.

However, an embodiment according to claim 43 is also possible, as a result of which pin contacts can be passed through these openings, with which, for example, a current conductor can be built up between the two rails of the track grate.

Due to the design according to claim 44, the components required for stiffening can be used simultaneously for supplying traction current or for signaling.

However, a further development according to claim 45 is also possible, as a result of which the track system according to the invention can be retrofitted to a so-called one at any time without great expense 3-wire track system can be retrofitted and with it the same parts for the normal two-wire track system and a 3-wire track system can be found.

Another embodiment variant is described in claim 49, whereby contacts provided with snap elements can be easily used for power supply, in particular in broken track sections or in the area of reversing loops, and for individual power supply along the track grating. In addition, the arrangement of monitoring organs, for example, can be used to control, for example, ice-filled alarm systems or barrier systems or the like via such monitoring organs arranged in the region of the rails of the track grate.

A further development according to claim 50 is also advantageous, since the necessary drives, monitoring and control devices for monitoring, controlling and actuating equipment parts of such track systems, for example ^* of point machines and the like, are thereby incorporated directly into the invention. track system according to the invention can be integrated and thus elaborate underfloor arrangements can be saved and nevertheless an "invisible" and thus real-world assembly is easily possible.

Any coupling of the switches with mechanical or motor drives enables the configuration according to patent claim 51.

An embodiment according to claim 52 is also advantageous. Due to the mechanics partially integrated into the stiffening elements, rigid mounting of the mechanical parts and thus exact adjustment of the adjustment paths can be carried out easily. The cutting lines expediently consist of grooves, so that these guides form scissors through corresponding lines of weakness.

A further embodiment according to claim 53 is also advantageous. Due to the deformation of the spring device perpendicular to the longitudinal direction when the adjusting lever is in the end position! in the direction of the end position an "over dead point lock" of the actuating lever is reached. Therefore, the switch tongue snaps, even if the switch is cut open, again and again into its end position on the same rail. The required deformation of the spring can be advantageous

Be used simultaneously to perform a switching function. This makes it possible to find an end with an even smaller and more compact structure of the mechanical drive, with the switching element also making polarization possible even when the switch is actuated purely mechanically, if one of the two is located on either side of the spring device Direction arranged contacts with one of the two rails in front of the switch is connected. If the switching flag is contacted with the heart via a cable or a conductor track, the heart is -14-

The tracks which can be embedded in the bedding parts are of conventional construction and, as can be seen from FIG. 1, consist of a one-piece track grating 1. A threshold band of the track grating 1 formed from plastic or plastic injection molding consists of the parallel tracks Thresholds 2, which are connected at least below one of the rails to be connected to them with connecting webs 3 parallel to the rails. The

Threshold band or the track grate 1 is provided in a uniform grid at the intersections of the connecting webs 3 with the thresholds 2 with blind holes 4, which allow the force-fit connection of a support device 5, such as e.g. serve a ladder-shaped stiffening element 6 by means of pins 7 which are pressed into it and held there in a force-fitting manner. Furthermore, individual sleepers 2 are provided in their central area with through holes 8 which, in a manner explained below, connect the tracks embedded in the bedding parts to the mounting plate by means of pins or nails or

Serve screws.

The track grate 1 can be seen in a perspective view from FIG. The rails 9,10 are attached to form the track grate 1 in such a way from the threshold band that they

Cover connecting webs 3 so that they do not appear from the top. The sleepers 2 formed by the sleepers 2, which may also be individual and not integrated into a sleeper band, and the rails 9, 10 fastened on the sleeper band, are of a known type and can be used by themselves -18-

alone in the usual way e.g. can be used by any shortening or the like to create track systems with any track diagrams. With the so-called flexible track gratings, which can be curved in different radii, a revealing radius-variable track design is also possible.

The bedding part Tl is provided for the bedding of the track grate. This consists of an injection molded part made of elastoplastic material and, in its basic shape, has the profile of an isosceles trapezoid without the lower, larger side or base in the case of non-track sticking. The bedding part 11 has a central part or central part 12, with which the beveled side parts 13, 14 are connected in one piece. According to a first embodiment, side parts 13, 14 are formed directly on the longitudinal side edges of the central part 12, which preferably also consist of an elastically deformable, flexible material, for example rubber or plastic, like the central part 12. The central part 12 is in its surface with a relief or a recess 15, the shape of which is complementary to the track grate 1, so that the track grate 1 can be inserted into the recesses 15 of the relief in such a way that the sleepers 2 of the track grate 1 the recesses in the direction of the rails only slightly transferred.

On its underside, the bedding part 11 is provided at the edge of the central and central part 12 with two parallel webs 17, 18 which delimit a groove between them. The respective inner webs 18 of the paired webs 17, 18 are higher than the respective outer webs

17. The outer webs 17 are provided on the inner edges of their edges with inwardly facing beads 19. The pair of webs 17, 18 arranged on the edges of the central or central part 12 serve to stiffen the profile and, moreover, also as a coupling part for coupling side parts 20, ^■ 19-

if the side parts 13, 14 are not formed in one piece with the central part 12. The side parts 20 can thus be provided with coupling parts of a connecting device, for example a groove with different cross-sectional areas, which are opposite to the central part 12.

The coupling part can be formed on the central part 12 by a web 17, 18 projecting over the underside, which preferably has a different thickness over its height.

The webs 17, 18 can be integrally formed on the central part 12 as a support device.

The bedding part is provided on its underside with oblique cutting lines 21, 22 which are formed by grooves and therefore form lines of weakness. The cutting lines run from the outer edge of the side parts 13, 14 to the ends of the bedding parts 11, specifically in the direction of the outside of the webs 17. Further cutting lines 23 are provided immediately adjacent to the outside of the webs 17. Due to their groove-shaped design, the cutting lines 21, 22, 23 offer good guidance when cutting out with scissors. The side parts 13, 14 can then be cut away obliquely if the bedding parts 11 are to be used for the bedding of tracks connected to a switch. If the side parts 13, 14 have been separated from the central part 12 by cuts along the section lines 23, the side parts 20 can be connected to the central part 12 on the webs 17, 18 by their complementary connecting profiles 24. In order to ensure the desired variability, the undersides of the side parts 13, 14 are provided with markings and / or lines of weakness.

To stiffen the bedding parts 11, ladder-shaped stiffening elements 6 can be connected to them. These consist of plastic injection molded parts made of a harder plastic. The -20-

Longitudinal bars 25, 26 of these ladder-shaped stiffening elements 6, which are connected to one another by rung-forming webs 27, are interrupted between one or more rungs or webs 27 alternately on opposite sides by a column 28. The column-shaped stiffening profile or stiffening element 6 can be curved in its plane through this column and also compressed and pulled apart to compensate for tolerances.

With individual rungs or webs 27, bush-shaped parts 30 are connected either directly or via attached webs 29, the bores 31 of which are aligned in the bedding part 11 and the bores 8 of the track grating 1. Through the aligned bores 8, 31, 32, nails or pins can be passed through on a mounting plate for mounting the track gratings 1 embedded in the bedding parts 11.

It is advantageous here if the parts 30 consist of a pressure-resistant material, for example a hard plastic or a soft plastic embedded sleeve, made of pressure-resistant rollers supporting parts which run approximately perpendicular to the track grating. As a result, an exact spacing is achieved during the assembly of the track grate 1 with the bedding parts 11 from the mounting plate essentially independently of the respective clamping force that is applied with the nail or the pin or the screw. Differences can then only arise in a different deformation of the very thin layer of the bedding part 1 between the support body and the sleepers 2 of the track grate 1. This elastic intermediate layer between the support body and the track grate, however, leads to considerable sound insulation and is therefore very advantageous for the intended use, so that, owing to the design of the support body, these advantages can be achieved simultaneously with an exact attachment of the track grate 1. -21 -

The distance between the longitudinal bars 25, 26 of the ladder-shaped stiffening elements 6 corresponds to the distance between the inner strip-shaped webs 18 of the bedding part 11, so that the ladder-shaped stiffening element can be inserted between these inner webs 18. For centering and holding 12 bowl-shaped receptacles 33 are connected to the underside of the upper wall and the central part. These cup-shaped receptacles 33 are provided with a recess in the cylindrical jacket for the parts 30 formed by bushes with these holding webs 29 and consist of two shells 34 formed receptacles for the parts 30 which are arranged centrally in the webs 27.

As can be seen in particular from the illustration in FIG. 9, a height 35 of the webs 18 or the receptacles 33 is slightly greater, for example, between 0.1 mm and 0.5 mm than the corresponding height of the support device or the stiffening element ¬ elements 6 or the longitudinal spars 25, 26 or webs 27 forming the same.

This makes it possible to pretension the elastically deformable or pliable plastic from which the bedding part 11 is made when fastening the track grate 1, so that this pretensioning can secure the fastening means against loosening and unscrewing in the event of vibrations in a surprisingly advantageous manner.

To fix the rail grating 1 inserted into the relief-like recesses 15, the longitudinal spars 25, 26 are provided with the pins 7, which penetrate the upper wall of the central part 12 of the bed part 11 in bores 36 and force fit into the blind holes 4 of the rail grating 1 to grab. -22-

The supporting devices or stiffening elements 6 stiffening the bedding parts 11 are expediently designed like a ladder and have rungs at least in the area of the fastening points of the track grating 1. The longitudinal bars 25, 26 of these ladder-like support devices or stiffening elements 6 are expediently interrupted.

The longitudinal bars 25, 26 of the ladder-shaped support devices or stiffening elements 6 have at their front ends opposing coupling parts 37, 38, each of which forms one part of a coupling device, for example a snap coupling device. The one coupling parts 38 are V-shaped or fork-shaped and have thickenings 39 at their mutually facing ends. The coupling part 37 is approximately arrowhead-shaped and, as can best be seen from FIG. 0a, has a shape that is complementary to the inner part of the coupling part 38.

The coupling device can thus be provided with locking pins extending in the longitudinal direction of the longitudinal bars. Furthermore, the coupling devices can have side and / or height guide members. For this purpose it is possible, for example, for the V-shaped or fork-shaped coupling point 38 to be half-shell-shaped and for the coupling part 37 to be conical or pyramid-shaped in its end facing the coupling parts 38, for example. As a result, a height and side alignment of the bedding parts or track grating 1 arranged one behind the other can be achieved at the same time by means of the coupling device.

In order to ensure the desired modularity of the system and to be able to create different track patterns, the adapter parts 40 containing the coupling parts 37, 38 can be provided, which are shown in FIGS. 8 and 10. ^■ 23-

8 shows a stiffening ladder-shaped support element or stiffening element 6 for a switch bed part. The adapter piece 40 can be connected to one end of the support profile by complementary coupling parts 41, 42. The ladder-shaped support profile is provided with a chamber-shaped recess 43, into which an electric switch drive 44 can be inserted.

It can be seen from FIGS. 9 and 19 that the connecting profile 24 of the separate side part 20 can be inserted or pressed into the groove formed between the longitudinal webs 17, 18 provided in pairs.

A continuous power supply line can be arranged in the central part 12 and / or the support device. The electrical coupling device for the power supply line can be formed by connecting devices arranged in the region of the front ends of the longitudinal bars.

FIG. 12 shows a track 46 in which a bedding part 11 is used which essentially corresponds to that shown in FIG. A track grate 1 is arranged in this bedding part 11. The bedding part 11 differs from the embodiment shown in FIG. 9 in that a support bracket 47 is formed or attached to the side part 13 outside the web 17. This support bracket 47 forms a cable channel for receiving cables 48 for controlling or supplying power to the track grate 1 or the built-in parts interacting with the track. The advantage of this arrangement lies in the fact that, as indicated by dashed lines, the side parts 13 can be lifted at any time by the slack or elastically deformable design, even when the track grating 1 is installed, in order to insert or damage new cables 48 or cables to be removed can be removed or replaced. Of course it is also how ^■ 24-

shown in the right part of FIG. 12 possible to use the free space extending between the leg or web 17 and the side part 13 without arranging a carrying strap 47 for arranging cables 48.

Furthermore, the embodiment shown in FIG. 12 differs from that shown in FIG. 9 in that the support device 5 is formed by disk-shaped stiffening elements 49. As can be seen better from FIG. 13, these disk-shaped stiffening elements 49 can also be designed in the manner of an oval, so that the bedding part 11 can be fixed on the support device 5 by the nose 50 of the webs 18 projecting over the mutually facing sides . However, it is also possible to manufacture these support devices 5, which consist of a hard, incompressible material, for example by a coextrusion or two-component injection molding process, in which case the bedding part 11 is made of a flexible, resiliently deformable plastic and the reinforcing element 49 is made of one resistant plastic material can be formed.

If the disk-shaped stiffening elements 49 are subsequently inserted into the bedding parts 11, it is also possible to connect the individual stiffening elements 49 via thin, flexible connecting webs 51. As a result, the stiffening elements 49 can also be perfectly centered and aligned in the circular arc or it is ensured that the holes or the through holes 8 and holes 52 in the stiffening element 49 are each in an overlapping position. As can be seen, these stiffening elements 49 can be provided with bores 52 for receiving fastening means 53 formed, for example, by screws. ^■ 25-

In the embodiment shown in FIG. 14, it is shown that the blind holes 4 arranged under the rails 9, 10 can also receive pins 7, which are subsequently inserted into the support device 5, for example in the disk-shaped stiffening element 49. Of course, they can also be produced in the manufacture of the disk-shaped stiffening element. It is advantageous here if the pins 7 in their area penetrating into the blind hole 4 are provided with a roughening, for example knurling or with transverse ribs or screw threads, so that there is a deliberate positive connection even with corresponding tolerances in the diameter of the pin 7 and the blind hole 4 comes.

Furthermore, it is shown in Fig. 14 that it is also possible to use the

To secure the support device or the disk-shaped stiffening elements 49 via its own fastening means 53 on a mounting plate 54 for receiving such a track, while the fastening means 53 for fastening the track grating 1 takes place with the interposition of the bedding part 11 after the bedding part 11 has been placed on the support device. This can also be done with a threaded screw, for example, if a holding disk 55 with an internal thread is arranged in the bore 52 of the supporting device 5 in the disk-shaped supporting device or the stiffening element 49. The tension between the support device 5 and the track grating 1 can thus be regulated very sensitively.

It is also shown in this embodiment that a side part 56 which engages in the groove 45 formed between the webs 17 and 18 forms a bed part 57 running parallel to the track planes. This can be arranged overlapping with another bedding part 58, as shown, so that a track spacing between two track gratings 1 running parallel to one another can be changed easily. In order to -26-

Reaching the true-to-life bedding surface even if the bedding parts 57, 58, as shown, cannot be produced without a joint due to a slightly larger track spacing, it is also possible to insert insert strips 59, each in the desired manner

Width can be cut from plates made in any dimensions.

This exemplary embodiment also shows that the bedding parts 57, 58 can be removed along the section line 23 after the side parts 13 have been cut off, and instead that between the webs 17 and 18 or into the groove 45 formed between them with the bedding parts 57 or 58 molded connection profile 24 can be snapped.

Another embodiment variant of a track 60 is shown in FIGS. 15 and 16. In this embodiment variant, a continuous central web 61 is provided, on which transverse webs 62 are formed or snapped on in the longitudinal direction of the track. These transverse webs 62 form supports 63, 64 for the central part 12 of the bedding part 11 in the area of the rails 9, 10. Pins 7 projecting in the direction of the track grating 1 are arranged on the supports 63, 64, which, as already explained, for example, with reference to FIG has been inserted or can be inserted into the sleepers 2 of the track grate 1 in order to position the track grate 1 in the central part 12 or in a fixed position relative to the support device 5 and its supports 63 and 64. To fasten the support device 5, 61 through holes 65 are provided in the center webs, which are penetrated by fastening means 53 with which the support devices 5 are fastened on the mounting plate 54. If, in addition, the rail grating 1 is to be screwed to the support device 5, through holes 65 can also be provided in the area of the crossbars 62, for which purpose support or spacing between the mounting plate 54 ^• 27-

and the track grate 1 supports 66 can also be arranged. By selecting the wall thicknesses or the width and the height of the center web 61, sufficient flexibility of the center web 61 and thus the support device 5 for deformations in the track plane or perpendicular to a mounting surface 67 on the mounting plate 54 can be achieved.

To fix the central part 12 laterally and in terms of height, the support device 5 can further be provided with coupling parts 68, which can be formed by support webs with a mushroom-shaped cross section running approximately parallel to the supports 63, 64. These coupling parts 68 are comprised of opposing coupling parts 69 which are formed, for example, by longitudinal grooves with a dovetail cross section. By the fact that the protrusions with the dovetail-shaped

Coupling parts with a cross-section which grip around the opposite projections of the coupling parts 68 with a mushroom-shaped cross-section also ensure that the central part 12 is fixed in terms of height. In the exemplary embodiment shown, the side parts 70 adjoining the central part 12 are connected to a coupling device 72 between the central part and the side parts 70 by a coupling device 71 formed by the coupling parts 68, 69.

As further indicated schematically in FIG. 16 by dash-dotted lines, it is also possible to provide 61 side webs 73 instead of the central web 61, which can be arranged alternately left or right at a distance from a longitudinal central axis 74. This also enables a flexible deformation of the support device 5 in the area of the mounting surface 67. To simplify a central structure of the support device along a predetermined track axis in this case, center markings 75 can be provided when using side bars 73 in the area of the cross bars 62. with which the support device 5 extends along a planned track axis -28-

can be aligned and attached. If center bars 61 are used in the support device 5, it is also possible to provide the center markings 75 instead of the center markings 75 by means of arrows or grooves, bores or elongated holes, which make it easy to center the support device 5 on a track axis, in particular of track arches.

Another embodiment of a support device 5 is shown in FIGS. 17 and 18, which also has a central web 61. In this case too, transverse webs 62 are fastened to the central web 61, or are integrally formed thereon. The central web 61 has a width 76 which makes it possible to deform the central web 61 on the mounting surface 67 of the mounting plate 54, so that it also assumes an arc-shaped, for example circular or basket-shaped, curve shown in FIG. 17 by a dash-dotted line 77 can. For vertical, lateral and longitudinal guidance of the central parts 12 of the bed parts 11 or of the track grating 1 consisting of sleepers 2 and rails 9, 10, center supports 79 are provided at a longitudinal distance 78 approximately centrally to through holes 65, in which also the through holes 65 are integrated. The longitudinal distance 78 preferably corresponds to a longitudinal distance 78 - FIG. 1 - between two through holes 8 in the sleepers 2 spaced apart from one another in the longitudinal direction of the sleeper band. The central part 12 has an approximately C-shaped cross section on its side facing the support device 5 Coupling part 80 comprising guide bar is provided, which is provided with a guide bar 82 acting as coupling part 81 and projecting beyond the width 76 of the central supports 79. Because the guide strips 82 are provided with inclined end faces 83 in the longitudinal direction of the support device 5, it is also possible to slide the central part 12 onto the guide strips 82 after the support device 5 has been mounted on the mounting plate 54. A central, central positioning of the track grate 1 on the support device 5 is thus possible. -29-

In addition, the central part 12 is supported against twisting or tilting via side parts 84, 85, wherein for example the side part 84 can form an oblique downward gravel bed flank and the side part 85 can form a flat connecting part to an adjacent track. These side parts 84, 85 now differ from the previously described side parts in that, as is indicated by differently dense hatching of the side parts 84 and 85 in the cutting area, the side parts in the area between the support device 5 and the central part 12 from one Deformation-stable plastic 86 and the area of the side parts 84, 85 which form the bedding parts consist of an elastically deformable, in particular additionally also limp plastic 87. The side parts 84 and 85 are either injection-molded or extruded in one operation, by mixing the two different plastic materials together in the mold, or first the parts of the side parts 84, 85 consisting of the plastic 87 or 86 are produced and the other parts are opened the prefabricated parts are sprayed or extruded by inserting the prefabricated parts into the mold.

In this embodiment too, it is therefore possible either to fasten the track grating 1 to the mounting plate 54 via fastening means through the through holes 65 or to glue it into the central part 12. In order not to hinder sufficient flexibility in the case of deformations of the track grate 1 along a line 77, it is also possible for the parts of the side parts 84 and 85 consisting of the rigid plastic 86, as indicated by dashed lines, with the center supports 79 facing recesses 88 which should enable an accordion-like bending of these parts of the side parts 84, 85. ^■ 30-

In the case of side parts 84 and 85, which are possible for the arrangement in connection with a so-called flexible track grating, which can therefore be deformed to any radii in the mounting surface 67, the wall thickness of the side parts 84 and 85 can be very small for such applications be held or designed with notches or ziehar onika-like in order to accommodate the longitudinal changes - on the outside of the curve and the extensions and on the inside the shortenings - without wrinkling.

To connect the individual abutting support devices 5, these can be provided with opposing coupling parts 41, 42. The coupling parts 42 consist of toothings 89 which are arranged in the region of the two side edges of the center webs 61 facing away from one another and into which a counter-toothing engages in the fork-like coupling parts 41.

If, as is indicated schematically in connection with the coupling part 41, the entire outside of the central web 61 is equipped or provided with a continuous toothing 89, the central parts 12 can be cut to any length and coupled again at any time. It is also possible, among other things, not to provide fork-shaped coupling parts 41, but sleeve-like coupling pieces, and to provide the middle webs exclusively with teeth 89 so that a sleeve-like coupling part 41 can be used in the connection area for coupling the teeth 89 of the two abutting support devices 5 .

Of course, it is also possible, in all the other exemplary embodiments shown, to provide corresponding toothing or coupling parts on the longitudinal webs or the central webs either over the entire length or in the area of their ends, so that any length of a stand is cut to length. -31 -

In addition, an additional coupling is made possible over a shorter length by means of the connection of the individual track pieces separated from the tabs between the individual rails.

FIG. 19 shows an embodiment variant of a support device 5 in the area of a switch, for example similar to that shown in the support device in FIG. 8. A central part 12 for receiving the track grate 1 is made from a coextrusion or multi-component injection molding. In the area of the fastening means or the end face 83, the central part 12 is made of deformation-resistant and hard plastic 86, while the support for the track grating 1 is formed by a soft, elastically deformable plastic 87, which may be pliable. The connection of side parts 90 takes place, as already explained with reference to FIG. 15, via coupling devices 71. In this exemplary embodiment, it is further shown that the side parts 90 can also be designed in a stepped manner and, for example, between the central part 12 of the support device 5 and the side parts 90 Point machine 44 can be located. This can be connected via a linkage 91 and a driver 92 with adjustable switch tongues 93. This makes it possible, for example, to couple the turnout drive 44 to a turnout lantern 95 arranged in the area of a step 94.

Such side parts 90 can, however, also be used instead of guiding and arranging switch lanterns 95 for receiving signal masts or overhead line masts 96, these overhead line masts being fastened via fastening means 53 directly in the mounting plate 54 or, if appropriate, also support strips arranged in lower side parts 90 .

In order to allow a corresponding free movement of the drivers 92 for adjusting the switch tongue 93, it is advantageous if an opening 126 is arranged in the bedding part 11. -32-

which can also be formed by an elongated hole, for example. Of course, in order to enable mechanical actuating elements or contact strips or the like to be connected to the rails, it is advantageous if corresponding openings in the bedding parts are provided or appropriately marked cutting lines are prepared at the necessary points, so that if necessary these transit points can be opened. This also applies to the recordings for carrying out signals or overhead line masts through the bedding parts or side parts thereof.

The attachment of the bedding part 11 in FIG. 19 can be achieved by fastening individual C-profile-shaped fastening elements or also a continuous hat-profile-like strip onto the mounting plate 54, onto which the bedding part consisting of a hard-soft profile is snapped on . The elasticity of the vertical legs of this bedding part 11 made of hard plastic is made possible by the areas made of elastic plastic in the transition to the contact surface for the sleepers 2.

For the sake of order, it should only be mentioned that in all of the exemplary embodiments in the present application, in order to better understand the invention and to simplify the illustration in the drawings, individual parts or all parts were partially disproportionately enlarged.

An embodiment similar to the bedding part 11 according to FIG. 9 is shown in FIG. However, this differs from the one described above in that in addition to the webs 17, 18, the longitudinal bars 26 and the parts 30 are integrally formed on the central part 12. As indicated schematically by different densities, the longitudinal bars 26 and the parts 30 consist of a deformation-resistant, rather hard plastic, while the remaining parts of the central bed -33-

tion part 11 or the side parts 13 consist of an elastically deformable, preferably pliable plastic. The longitudinal bars 26 and the parts 30 as well as the pins 7, which are also integrally formed on the longitudinal bars 26, thus form the stable, dimensionally stable framework for the track. Furthermore, it can be seen from this illustration that a distance between an underside of the threshold 2 facing the central part 12 and the mounting surface 67 of the mounting plate 54 corresponds to the height of the webs 18 or receptacles 33. A height 97 between the underside of the sleepers facing the central part 12 and the underside of the longitudinal spars 26 or parts 30 facing the mounting plate 54 is slightly less, for example, between 0.1 mm and 0.5 m than the height of the webs 18 or the receptacles 33. If the track grating 1 is now fastened directly to the mounting plate 54 by means of a fastening means 53, then when the fastening means 53 is tightened, for example a screw, the plastic forming the webs 18 or receptacles 33 is indicated, compressed or schematically as shown in dashed lines elastically deformed. This deformation continues until the end face of the longitudinal spars 26 or the parts 30 assigned to the mounting plate 54 abuts on the mounting surface 67. This elastic prestressing of the webs 18 or the receptacles 33 indirectly achieves screw locking, since the fastening means 53 cannot loosen even in the event of vibrations acting on the track.

Nevertheless, the interposed elastically deformable and thus vibration-damping layer of the central part 12 between the receptacles 33 and the underside of the sleepers 2 facing them achieves vibration and, above all, noise insulation.

Another embodiment of a coupling device 98 is shown in FIGS. 21 to 23. This consists of a coupling part 99 that either directly on a longitudinal beam 26 or -34-

a central web 61 is integrally formed or connected by means of coupling parts 41, 42. The opposite coupling part 100 opposite the coupling part 99 is fork-like equipped with two fork tines 102 resilient in the direction of the arrows 101. Between the two fork tines 102, a centering opening 103 is arranged in the coupling part 100, which is formed, for example, from a bore running parallel to an axis of symmetry 104. If the coupling part 100 is now pushed onto the coupling part 99, the fork tines 102 are pressed apart and snap over a thickening 105, so that a separation of the coupling device 98 is only possible by overcoming the deformation energy of the fork tines 102. At the same time, the coupling part 99 is equipped with a guide pin 106 directed in the direction of the centering opening 103, which is conical at its end facing the coupling part 100. When the two coupling parts 99 and 100 are plugged together, the guide pin 106 is pushed into the centering opening 103 and the longitudinal bars of the abutting track parts are thus fixed not only in their position parallel to the longitudinal direction of the sleeper but also perpendicular to the track plane.

24 and 25 show a further coupling device 107, which enables a connection with longitudinal bars 26 or central webs 61 at any point along the longitudinal course of the support devices 5 and at the same time a lateral and vertical guidance and alignment of the support to be connected ¬ directions 5 allows. This coupling device comprises a sleeve part 108 which is pushed onto ends 109, 110 which are immediately adjacent to one another from above. A continuous groove 111, which has a C-shaped cross section, is arranged on the longitudinal spar 26 or the central web 61 on the side facing away from the mounting plate 54. The sleeve part 108 is provided with a centering strip 112 and has the teeth 89 on the two side walls of the longitudinal bars 26 and ^■ 35-

Center arms 61 assigned snap arms 113, which are radially elastically deformable by a weakening point 114 relative to the housing part holding the centering strip 112.

If the sleeve part 108 is now plugged and snapped onto the two ends of the longitudinal spars 26 or central webs 61 to be connected from above, this results in a rigid connection and precise alignment both in the longitudinal direction of the track and in the vertical and lateral directions achieved, which can be solved at any time. If the longitudinal spars 26 or central webs 61 are accordingly equipped with continuous toothing as coupling part 69, they can be connected at any point by the sleeve parts 108. Of course, such sleeve parts can be used as adapter pieces 40 for support devices 5 designed in switch form. On the other hand, however, it is also possible at any time to mount the adapter pieces 40 even with normal support devices by subsequently snapping them on if they are to be connected via a coupling device.

26 and 27 show bedding parts 115, 116 for double glazing which should be arranged at a fixed distance from one another. The structure of the bedding parts relating to each of the two tracks 117, 118 corresponds, for example, to the structure as shown in FIGS. 1 to 7 or FIG. 9 or FIG. 20 or the other exemplary embodiments explained in the above description.

The two bedding parts 115, 116 differ from one another only in that the bedding part 115 is provided for a straight-line double bed by the two bedding 117 and 118 running in a horizontal plane. The bedding part 116, on the other hand, is provided for a double layer in the area of a sliding arch, bearing surfaces 119 for the sleeper 2 of the sliding surface 117, 118 by an elevation angle 120 -36-

run inclined to each other. This inclination can slowly increase at the beginning of the curve and then decrease again towards the end of a 90 ° curve, for example. However, corresponding bedding parts can also be provided for a semicircular circular arch, which have a corresponding transition arch to achieve a maximum elevation and then have a transition arch back onto the horizontal track. If necessary, it is also possible to produce your own bedding parts which have the corresponding transition arches, so that bedding parts 116 with a fixed cant can be provided, which can be assembled to form an arbitrarily long arch and which have transition pieces with the horizontally running track parts get connected.

Of course, it is also possible that the differently designed support bodies can be combined in connection with the most varied coupling devices as described on the basis of the various exemplary embodiments, and individual combinations of characteristics of the individual exemplary embodiments can form independent solutions according to the invention .

Connecting elements can be provided which penetrate the support device between the track grate and a support surface receiving the bedding body.

In the central part, recesses can be provided below the rails, into which contact devices between the rails and the power supply line can be inserted. Receptacle bases for signals or overhead line masts can be integrated in the side parts. -37-

In order to enable a state of the model track bedding that corresponds as exactly as possible to reality, it is also possible, as further shown schematically in FIG. 20, to produce the bore or the through hole 8 as a blind hole 121, so that an upper end face 122 of the sleeper 2 is continuous . If the bore or the through hole 8 is required, it is possible to pierce an end face 123 from the side of the blind hole 121. Likewise, the pin 7 can also be guided in a blind hole 121 below the rail, so that no opening in the end face 122 of the threshold 2 can be seen from the rail 9 or 10.

In order to obtain a reproduction of the structure of the track bed that is as exact as possible according to the actual circumstances, it has proven to be particularly advantageous if, particularly in the soft, elastically deformable, preferably pliable plastic 87, as also shown schematically in FIG. 20, a granulate 124 is mixed into the raw material before production of the bedding part 11. With appropriate choice of material, these granules 124 are not melted during the injection molding process or extrusion process of the bedding parts 11 or the central part 12 or the side parts 13 and are therefore embedded in the liquid melted plastic. If the shape in those areas in which a gravel representation and a rough gravel structure corresponding to the actual conditions is desired is provided with a surface roughness which corresponds approximately to a part of the grain size of the granules 124, then a surface is formed on a surface surface 125 of the bedding parts has the structure shown in part of the side parts 13 in FIG.

It is particularly advantageous if the granules 124 are formed by appropriately colored rubber particles or plastic particles with a higher melting temperature. However, it is also possible to use mineral granules in the -38-

wanted to mix grain size into the raw material. Nevertheless, it is ensured that in the area in which the mold has a smooth surface, the molded part also has a smooth surface and thus an exact position, for example of the sleepers of the track body, is achieved in the bedding part.

As is also shown in FIGS. 21 and 22, it is also possible to design the centering opening 103 and the guide pin 106 as a carbon pin or a metal pin, in order to enable an electrical connection between the individual support devices. The guide pin 106 and the centering opening 103 can be contacted with cables 127 in order to enable a continuous power supply to the track. By inserting appropriate contact pieces from below, it is also possible to repeatedly connect the rail network to the continuous contact rail in a plurality of areas spaced apart from one another. It is also advantageous here if the entire longitudinal spars 26 or central webs 61 are formed from conductive plastic, for example with PVC or graphite mixed with graphite or the like, it being advantageous if, in the case of a plurality of longitudinal spars running parallel to one another, the connection between them that is transverse to runs the rails 9, 10, is designed to be insulating.

The tracks which can be embedded in the bedding parts are of conventional construction and, as can be seen from FIGS. 28 to 31, consist of a one-piece track grate 201. A sleeper band of the track grate 201 made of plastic or plastic injection molding consists of the mutually parallel sleepers 202 which are connected at least below one of the rails to be connected to them with connecting webs 203 parallel to the rails. The sleeper band or the track grate 201 is provided in a uniform grid at the intersections of the connecting webs 203 with the sleepers 202 with blind holes 204, which provide the non-positive connection of a support device. -39-

device 205 such as a ladder-like stiffening element 206 by means of pins 207 which are pressed into it and held in a force-fitting manner therein. Furthermore, individual sleepers 202 are provided in their central region with through holes 208 which, in a manner explained below, serve to connect the tracks embedded in the bedding parts to the mounting plate by means of pins or nails or screws.

31 shows the track grating 201 in a perspective representation. The rails 209, 210 are fastened to form the track grating 201 in such a way from the sleeper band that they cover the connecting webs 203 so that they do not appear from the top. The track 202 formed by the possibly individual sleepers 202, which are not integrated into a sleeper band and the rails 209, 210 fastened thereon, is of a known type and can be used in the usual way e.g. can be used by any shortening or the like to create track systems with any track diagrams. With the so-called flexible track gratings, which can be curved in different radii, a freely radius-variable track design is also possible.

The bedding part 211 is provided for bedding the track grate. This consists of an injection molded part made of elastoplastic plastic and, in its basic form, has the profile of an isosceles trapezoid without the lower larger side or base in the case of non-track sticking. The bedding part 211 has a central part or central part 212, with which the beveled side parts 213, 214 are integrally connected. According to a first embodiment, side parts 213, 214 are thus integrally formed on the longitudinal side edges of the central part 212, which preferably also consist of an elastically deformable, pliable material, for example rubber or plastic, like the central part 212 -40-

Central part 212 is provided in its surface with a recess 215, the shape of which is complementary to the track grate 201, so that the track grate 201 can be inserted into the recesses of the recess 215 in such a way that the sleepers 202 of the track grate 201 have the recesses only slightly transferred in the direction of the rails.

On its underside, the bedding part 211 is provided at the edge of the central or central part 212 with two mutually parallel webs 217, 218, which delimit a groove between them. The respective inner webs 218 of the webs 217, 218 provided in pairs are higher than the respective outer webs 217. The outer webs 217 are provided on the inner edges of their edges with inwardly pointing beads 219. The pairs arranged on the edges of the central or central part 212

Crosspieces 217, 21 serve to stiffen the profile and, moreover, also as coupling parts for coupling side parts 220 if the side parts 213, 214 are not formed in one piece with the central part 212. The side parts 220 can alos be provided with coupling parts of a connecting device, for example a groove with different cross-sectional widths, which are the same as the central part 212.

The coupling part can be formed on the central part 212 by a web 217, 218 projecting over the underside, which preferably has a different thickness over its height.

The webs 217, 218 can be formed on the central part 212 as a supporting device.

The bedding part is provided on its underside with oblique cutting lines 221, 222 which are formed by grooves and therefore form lines of weakness. The cutting lines run from the outer edge of the side parts 213, 214 to the ends of the bedding parts 211, in the direction of the -41 -

Outside of the webs 217. Further cutting lines 223 are each provided directly adjacent to the outside of the webs 217. Due to their groove-shaped design, the cutting lines 221, 222, 223 offer good guidance when cutting out with scissors. The side parts 213, 214 can then be cut away obliquely if the bedding part 211 is to be used for the bedding of tracks connected to a switch. If the side parts 213, 214 have been separated from the central part 212 by cuts along the section lines 223, the side parts 220 can be connected to the central part 212 on the webs 217, 218 by their complementary connecting profiles 224. In order to ensure the desired variability, the side parts 213, 214 are provided on their undersides with markings and / or lines of weakness.

To stiffen the bedding parts 211, ladder-shaped stiffening elements 206 can be connected to them or they can be produced by a multi-component injection molding. These consist of plastic injection molded parts made of a harder plastic. The longitudinal spars 225, 226 of these ladder-shaped stiffening elements 206, which are connected to one another by rung-forming rungs or transverse webs 227, are alternately interrupted by columns 228 between one or more rungs on opposite sides. This column allows the ladder-shaped stiffening profile or stiffening element 206 to bend in its plane and also to compress and pull apart to compensate for tolerances.

With individual rungs or transverse webs 227, bush-shaped parts 230 are connected either directly or via attached webs 229, the bores 231 of which, when inserted in the bedding part 211, are aligned with bores 232 of the bedding part 211 and the through holes 208 of the track grate 201. Through the aligned through hole 208 and the holes -42-

231, 232 can be used to mount the track gratings 201 embedded in the bedding parts 211 on a mounting plate through nails or pins.

It is advantageous here if the parts 230 consist of a pressure-resistant material, for example a hard plastic or a soft plastic embedded sleeve, of pressure-resistant rollers supporting parts that run approximately perpendicular to the track grating. As a result, an exact spacing is achieved when installing the track grating 201 with the bedding parts 211 from the mounting plate, essentially independently of the respective clamping force that is applied with the nail or the pin or the screw. Differences can then only result in a different deformation of the very thin layer of the bedding part 211 between the support body and the sleepers 202 of the track grate 201. However, this elastic intermediate layer between the support body and the track grate leads to considerable sound insulation and is therefore very advantageous for the intended use, so that due to the design of the support body these advantages can be achieved at the same time as an exact attachment of the track grate 201 .

The distance between the longitudinal bars 225, 226 of the ladder-shaped stiffening elements 206 corresponds to the distance between the inner strip-shaped webs 218 of the bedding part 211, so that the ladder-shaped stiffening element can be inserted between these inner webs 218. For centering and mounting, cup-shaped receptacles 233 are connected to the underside of the upper wall and the central part 212. These cup-shaped receptacles 233 are provided with a recess in the cylindrical casing for the parts 230 formed by bushings with these holding webs 229 and consist of two cups 234 formed receptacles for the parts 230, which are arranged centrally in the transverse webs 227. -43-

As can be seen from the illustration, a height 235 of the webs 218 or the receptacles 233 is slightly greater, for example, between 0.1 mm and 0.5 mm than the corresponding height of the stiffening elements 206 or the support device 205 or the longitudinal bars forming the same 225,226 or crossbars 227.

This makes it possible to pretension the elastically deformable or pliable plastic from which the bedding part 211 is made when the track grate 201 is fastened, so that this pretensioning can secure the fastening means against loosening and unscrewing in the event of shocks in a surprisingly advantageous manner.

To fix the rail grating 201 inserted into the relief-like recesses 215, the longitudinal spars 225, 226 are provided with the pins 207, which penetrate the upper wall of the central part 212 of the bedding part 211 in bores 236 and engage in the blind holes 204 of the rail grating 201 with a force fit.

The support devices 205 stiffening the bedding parts 211 are expediently designed in a ladder-like manner and have rungs at least in the region of the attachment points of the track grate 201. The longitudinal bars 225, 226 of these ladder-like support devices 205 are expediently interrupted.

The longitudinal bars 225, 226 of the ladder-shaped stiffening elements or support devices 205 have coupling parts 237, 238, which are the same at their ends, and each form the one part of a coupling device, for example a snap coupling device. The one coupling parts 238 are V-shaped or fork-shaped and have thickenings 239 at their mutually facing ends. The coupling part 237 is approximately -44-

arrowhead-shaped and, as can best be seen from FIG. 37, has a shape that is complementary to the inner part of the coupling part 238.

The coupling device can also be used in the longitudinal direction

Longitudinal spar locking pins are provided. Furthermore, the coupling devices can have side and / or height guide members. For this purpose it is possible, for example, for the V-shaped or fork-shaped coupling parts 238 to be half-shell-shaped and for the coupling part 237 to be conical or pyramid-shaped in its end facing the coupling parts 238, for example. As a result, a height and side alignment of the bedding parts or track grating 201 arranged one behind the other can be achieved at the same time by means of the coupling device.

As can also be seen from the illustrations in FIG. 29, weakened areas 240 or openings 241, which are in the area of the intermediate compartments, can be formed in the bedding part 211 or its central part 212 on the side facing away from the recesses 215 for the sleepers 202 of the track grate 201 can be arranged between the thresholds or independently thereof. It is advantageous if these breakthroughs 241 or the weakening areas 240, preferably centered on a central longitudinal axis 242 of the bedding part 211 or the central part 212, are preferably centered between two recesses immediately adjacent to one another in the direction of the central longitudinal axis 215 are arranged. Such an arrangement makes it possible, among other things, to pass contact pins 243 through these openings 241 or weakened areas 240, as best seen in FIG. 31, so that a row of contact pins 243 can be formed between the two rails 209, 210. These can be used to introduce supply voltages or control signals into model vehicles provided with appropriate customers. Using this -45-

It is therefore also possible for contact pins 243 to use the bedding system or bedding parts 211 described in connection with a so-called 3-wire system.

The bedding parts 211 or central parts 212 can be produced uniformly, for example, only with the weakening areas 240, so that the user who wants to manufacture a 3-wire system can break through the openings 241 into this weakening area 240 by pressing the contact pins 243 can manufacture itself. However, it is also possible to manufacture the bedding parts 2! 1 or central parts 212 using the same tools and to make the openings 241 in the factory for those groups of customers who use a 3-pipe system in order to supply them directly to be able to.

Another embodiment variant for a stiffening element 206 is shown in FIG. 31, which is equipped with a continuous central web 247. 227 parts of longitudinal spars 225 and 226 are connected to the central web 247 via cross webs. Gaps 228 are arranged between the individual parts of the longitudinal spars 225, 226, so that the individual sections of the longitudinal spars 225, 226 do not hinder one another when the central web 247 is deformed to produce an arcuate track course.

On this continuous central web 247, the so-called intermediate compartments 248 arranged between the recesses 215 for the sleepers 202 of the track grating 201 are assigned weakening areas 240 on the side facing the stiffening elements 206. Contact pins 249 attached to the central web 247 are assigned to these weakening areas 240. When the bedding part 211 is placed on the stiffening element 206, the contact pins 249 can be designed accordingly -46-

Weakness areas 240 are pierced in the bedding part 211, so that the contact pins 249 protrude beyond the intermediate compartments 248 in the direction of a running surface of the rails 209, 210.

To supply power to the individual contact pins 249, these can be connected via a conductor 250, which can also consist, for example, of a conductor track applied to the central web 247 or a conductive plastic. The connection to the adjacent bedding parts 211 or central parts 212 or their central webs 247 is made via a coupling tab 251 or via contact areas 252 arranged in the area of the coupling parts 237, 238. For this purpose, the conductor 250 can be connected to these contact areas 252, or a conductor track be guided into the area of the contact surfaces 252.

As further shown in FIG. 32, it is possible for the contact pins 243 to consist of a conductive material, for example a metallic material. For example, it is possible to use a continuous metal strip as a support strip 244, from which the contact pins 243 are released and are bent upwards by 90 °. In the area between the individual contact pins 243, retaining bolts 245 can also be notched, with which the support strip 244 on transverse crosspieces 227 between the longitudinal spars 225,226 or via corresponding transverse arms or notches directly on the longitudinal spars 225,226 or, in the case of stiffening elements 206, with a central web 247 are snapped on directly at Mittelsteg 247.

It is of course also advantageous here if the support strip 244 has a shape which, especially in the case of so-called flexible tracks, which can thus be deformed to different radii in the assembly plane, can also be deformed in this direction, so that they are seamless be able to adapt to the changed radius ratios of a track. -47-

To connect the individual contact pins 243 in the various bedding parts 211 or central parts 212, it is possible for the support strip 244 to be provided, for example, with connecting lugs 246 of the same type as the connecting lugs 246 between the rails 209, 210 of the individual parts of the track grate 201, so that when the individual parts of the track grate or the individual pieces of the rails 209, 210 are plugged together with the coupling of the rails and to produce a continuous roadway, the electrical contact between the support strips 244 also takes place. However, the connection can also be made via cables connected to the individual support strips 244 or soldered to them and via corresponding plug connections.

In FIG. 33 it is shown that a bedding part 211 is fastened to a mounting plate 254 on a schematically indicated fastening means 253 and consists of a soft, elastically deformable, in particular limp plastic - as is indicated by the loose hatching. This is made of rigid plastic - indicated by tight hatching - associated with longitudinal bars 225, via which the track grating 201 or the rails 209 and sleepers 202 can be appropriately spaced from the mounting plate 254.

To use such a bedding part 211 in a so-called 3-conductor track system, a weakening area 240, for example a corresponding recess, is provided in an intermediate compartment 248 in the bedding part 211, which is only covered with a very thin material layer 255. This can be pierced by a contact pin 243, which can be carried on an upright support profile 256 with a rectangular cross-section. The support profile can preferably have a length corresponding to the bedding part 211 and in the area -48-

of the through holes 208 penetrating the thresholds 202 are provided with a lateral penetration 257 in order to avoid these through holes 208.

Another embodiment variant of a bedding part 211 for a 3-conductor track system is shown in FIG. Contact pins 243 are in turn arranged on a flat profile !, which forms a support profile 258, for example by welding, soldering or by notching out of the support profile 258, the weakening areas 240 or openings 241 in the bedding part 211 in the area of an intermediate compartment 248, i.e. between two sleepers 202 and preferably penetrate centrally between rails 209 and 210. The contact pins 243 are preferably arranged on a longitudinal central axis 259 which also forms an axis of symmetry of the track. The support profile 258 is placed on the stiffening element, of which a longitudinal bar 225 is shown, or on the crossbars 227 connecting the longitudinal bars 225, 226. For contacting the support profile 258 or the contact pins 243, it is now also possible to design the plastic of the bedding part 211 in this area as a conductor track 260, so that a continuous power supply to the contact pins 243 can take place. Of course, as indicated by dashed lines, it is also possible for the support profile 258 or the contact pins 243 with corresponding anchoring elements such as plates or the like to be inserted directly into the plastic of the bedding element 211, preferably in the electrically conductive ones designed as a conductor track 260 Plastic is poured or injected.

In Fig. 35 the Tragprofi1 258 is shown in plan view. The support profile 258 is provided between the individual contact pins 243 with notches 261, which allow deformation to any radii parallel to the mounting plate 254. -49-

Another embodiment variant for a 3-conductor track system is shown in FIG. This again includes the already known bedding parts 211, which have a central part 212 and side parts 213. A stiffening element 206 is provided to support the bedding parts 211, which consist of an elastically deformable, preferably pliable plastic. This stiffening element 206 comprises longitudinal spars 225, 226, of which only the longitudinal spar 225 can be seen. The longitudinal spar 226 is arranged as a mirror image of a longitudinal central axis 259. The contact pins 243 for the middle power supply line lying between the rails 209, 210 are fastened via support sleeves 262 to transverse struts 263 running transversely to the longitudinal direction of the bedding parts 211. These cross struts 263 are snapped onto a mushroom-shaped extension 265 of the longitudinal spars 225, 226 via snap elements 264 which enclose a groove between them. The individual transverse struts 263 can be contacted via a line 266 running parallel to the longitudinal spars 225, 226, for example a copper wire, or else through the longitudinal spars 225, which can be provided with a corresponding coating or can be electrically conductive.

37 shows that the contact pins 243 penetrate the central part 212 in intermediate compartments 248 between the individual sleepers 202. Furthermore, it is shown that the through holes 208 in the sleepers 202 are not obstructed by such an arrangement of the contact pins 243. The contact pins 243 therefore penetrate the central part 212 in openings 241, which are also produced during manufacture. The bedding parts 211 are in turn fastened to mounting plates 254. In order not to have to snap each individual contact pin 243 individually onto the longitudinal bars 225, 226, it is also possible to arrange them on a support profile 267, so that the distance between the individual contact pins 243 is predetermined. As shown in the right part of Fig. 37, the central part -50-

212 can also be seen only with corresponding weakening areas 240 which are penetrated when the contact pins 243 are inserted. Of course, the power supply can be carried out directly by the support profile 267 when using a support profile 267 instead of the line 266. However, it is also possible to maintain the power supply via line 266 and to produce support profile 267 from a flexible plastic.

38 shows a ladder-shaped stiffening element 206 for a bedding part of a switch. The ladder-shaped stiffening element 206 is provided with a karamer-shaped recess 268, into which a mechanical module 269 and an adjusting module 270 can be inserted on the side of the stiffening element 206 facing away from the bedding part 211.

39 shows the mechanical module 269 and the adjusting module 270. As can be seen on a floor plate

271 which is arranged in the stiffening element 206, arranged pivot axis 272 an adjusting lever! 273 postponed. The jack! is essentially T-shaped, the leg forming the crossbar being placed asymmetrically on the other leg. In the area of a shorter leg part 274, a coupling pin 275 is arranged, on which an adjusting lever 276 is pushed. The leg running perpendicular to the crossbar is connected to the pivot axis

272 is formed by a frame part 277, to which an actuating arm 279 which is elastically deformable in the setting direction - double arrow 278 - adjoins. In the interior of the frame part 277, a helical spring 281 is arranged in a motion-connected manner via an extension 280, which is pushed in its end region facing away from the extension 280 on a bending rod 282 which is fastened to the base plate 271 on its end facing away from the helical spring 281 . The bending rod 282 is provided with a line 283 which leads to a plug 284 in the area of the longitudinal -51 -

holmes 225 leads, coupled. In addition, 282, contacts 285, 286 are provided on both sides of the bending rod, each of which is contacted with a conductor track 287, 288. Each of the two conductor tracks 287, 288 is in contact with that rail 209 or 210 of the track grate 201 which is arranged on the side of the bending rod 282 opposite the contact 286 or 285. If a cable 289 connected to the centerpiece of the switch which is arranged isolated from the other rails is inserted into the connector 284, the centerpiece is polarized correctly depending on the position of the switch or switch tongue and thus of the frame part 277.

For manual adjustment of the actuating arm from the position shown in dashed lines to the full lines in which the switch tongues alternately rest on one of the two rails 209 or 210, the frame part 277 can extend over the longer part of the beam-like leg 290 of the T-shaped one Setting lever 273 can be operated.

However, the mechanical module 269 with an adjusting lever 276 of the

Adjusted module 270 coupled, the switch tongues can also be adjusted automatically. For this purpose, the setting lever 276 has a recess 291 in a setting plate 292, which is adjustably arranged in the interior of two opposing coils 293, 294.

The two coils 293, 294 each consist of crossheads 295, which are kept at a distance from one another via two longitudinal bars 296 and which are wound with a coil wire 297. Depending on the application of one of the two coils 293, 294, the setting plate 292 is shifted from the position shown in dashed lines to the position shown in dashed lines. Furthermore, extensions 298 of limit switches 299 are assigned to a recess opposite one of the recess 291 of the setting plate 292, which limit switches 299 -52-

When the extension 298 is in the end position, interrupt the power supply to the coils 293, 294 and thus ensure that there is no overheating of the coil body or the winding.

In FIG. 40 it can be seen that the longitudinal spars 296 which connect the crossheads 295 have a thickness 300 which corresponds approximately to the thickness of the setting plate 292 and are likewise arranged at a distance from one another which corresponds to a width 301 of the setting plate 292. The crossheads are also provided with openings 302, the cross section of which essentially corresponds to the cross section of the adjusting plate 292.

In addition, recesses 303 are arranged in the housing of the control module - FIG. 38 - in which magnetic surfaces 304 which surround the coils 293 and 294 are inserted. This ensures a very low overall height of the control module.

The bedding system described can of course be used for a wide variety of track gauges on model trains, for example N, HO, HOe, I, Um. Furthermore, the control modules or mechanical modules described are not only suitable for switches but also for crossing switches, curved switches but also for actuating decouplers.
