Definitions
- the invention relates to a model railroad track for electric model railways, with a trapezoidal, elongated, gravel structure, track body, on the upper side of which two metallic rails are fastened to sleepers, which has a lower side serving as support and two has end connection areas for the electrical and mechanical connection of a neighboring rail.
- the track body is made of thin sheet metal, which is shaped in the gravel structure and is open at the bottom.
- the connection of adjacent model railroad tracks takes place at the front connection areas by means of electrical contact tongues which are electrically connected to the rails or a central conductor and, in addition to the electrical contact, also ensure the mechanical hold of adjacent, interconnected rails.
- connection areas of two adjacent rails which are expressed on the one hand as a gap, or as an offset, projection or the like, and have the effect that the connection area of two rails can be easily recognized, in any case disturbing the observer's eye.
- the connection areas of the known model railroad tracks are also not suitable for a permanent mechanical connection of adjacent rails.
- the contact tongues which essentially serve for the electrical connection only result in a relatively weak mechanical cohesion, so that the gaps already described can occur between adjacent rails.
- the attachment of the rails is also associated with considerable effort and time.
- the object of the invention is to provide a model railroad track which allows a more realistic replica and, as a prerequisite for this, provides connecting areas which have a coupling which is much more precise and which enables mechanically better cohesion of adjacent tracks.
- each of the two connecting areas has only a bottom side and a recess open to the connecting plane, which has an undercut, and a separate one, to the connecting plane Symmetrical connecting element is provided, which can be inserted with a positive fit in the recess of the connection area.
- connection of adjacent rails is not provided by electrical and mechanical coupling means provided exclusively on the model railroad tracks, but rather an additional connecting element is provided for the mechanical and preferably also electrical connection of adjacent rails, which brings about a reliable mechanical cohesion of adjacent rails and so that the prerequisite for a very precise, gap-free collision of two adjacent tracks is created.
- a particular advantage of the connections obtained in this way is that each individual model railway track can be individually lifted up out of a series of interconnected tracks because no contact tongues projecting relative to the connecting plane are required, which force the model railway tracks to be pushed together in their longitudinal direction.
- the connecting elements allow a very large and thus effective mechanical cohesion of adjacent model railway tracks.
- the production of the recesses is relatively simple, preferably the recesses also have the simplest possible geometric shape, for example pitch circle shape, hexagon shape, push button shape or the like.
- connection areas ensures that the adjacent model railroad tracks are always clean and free of gaps.
- the connection areas are practically no longer recognizable with a suitable design of the model railroad track, contact tongues are not necessary, so that the rails also run through the area in the area of the connection in accordance with the great model, at least no thickening points, as caused by the contact tongue.
- the connecting element for the electrical connection of adjacent model railroad tracks.
- the connecting part has contact surfaces which are electrically connected to one another and are located on its upper side or on its side surfaces. On the underside or the side surfaces of the recesses of the model railroad tracks, these contact surfaces are provided with contact zones, at least two of which are electrically connected to the rails.
- connecting elements thus not only bring about a mechanical but also an electrical connection of adjacent rails. It is very favorable here that the electrical connection is not only possible for two electrical contacts, as in the previously known model railway track, but that a significantly larger number of connections can be seen before.
- the relatively large area of the contact elements is also advantageous here, which can take up a considerable proportion, for example 50 to 70%, of the width of a model railroad track. Due to the relatively large surface, a larger number of contact surfaces that can be made sufficiently large can be accommodated without having to maintain excessive accuracy during production.
- the electrical contact surfaces of the connecting elements are also designed to be fold-symmetrical to the connecting plane, so that the two halves of the connecting element can perform identical functions and can therefore be exchanged without any problems.
- the electrical contact surfaces are not provided on the connecting elements, but on the end faces of the model railroad tracks. They are preferably designed to be elastically resilient and can be pushed back elastically behind the connection plane, so that they do not impede a close, precisely fitting contact between two adjacent end faces, but nevertheless enable a very precise spring contact for the power line.
- the connecting elements are preferably also fold symmetrical to a plane of symmetry running through the longitudinal center of neighboring model railway tracks. This improves their universal use, and the assembly of model railroad tracks with them is simplified. In addition, if the bottom and top of the connecting elements are identical and each provided with contact surfaces, a special arrangement or alignment of the connecting elements is no longer necessary because they always fit.
- the connecting elements have two head regions which are connected to one another via a central web. This web is narrower than the head areas, whereby a positive fit is achieved.
- a second positive connection is possible, which acts transversely to the plane of the two rails.
- a push-button connection is provided, for example, which is provided between each half of the connecting element and a part of the recess in the model railroad tracks.
- the web between the two heads of the connecting elements can preferably be designed to be elastic, as a result of which the two connecting areas of adjacent model railway tracks are pulled elastically against one another in the connected state, whereby a gap in the connecting area is reliably avoided and a very good mechanical hold is achieved .
- the measure also improves the electrical connection.
- the track body is essentially made as a full body and made of plastic.
- the plastic construction enables on the one hand very simple insulation of the electrical lines, but in particular the rails.
- the plastic track bodies have the advantage, however, that the track edges do not have to run in a straight line, but that any course can be reproduced, as they also occur with the large prototype. In this way the track wins body a much more natural shape and appearance.
- the track bodies are preferably made from a plastic material using the casting process, the rails being cast in at the same time and the sleepers also being formed.
- the connecting elements with electrical connections for the voltage supply to the tracks and possibly other parts.
- the electrical voltage supply ' is no longer on the tracks, but on the connecting elements, which simplifies the manufacture of the tracks and in particular it is no longer necessary to use so-called connecting tracks and normal, i.e. no electrical connection, tracks when building a railway system.
- the electrical connections can easily be made on the connecting elements, for example plug contacts can be provided on each connecting element, into which connecting wires can be plugged in - if a connecting element is to be used as a connecting piece.

- Fig. 11 is a perspective plan view illustration of a connecting piece for the Modelleisenbahn ⁇ track according to FIG. 10
- FIG. 12 is a sectional view through the junction plane of two M o d e l railway tracks gem.
- FIG. 13 shows a perspective illustration of a connecting piece similar to FIG. 11.
- a model railway track for electric model trains is shown, which is constructed from a track body 20 which is trapezoidal in profile, elongated and has a ballast structure 18, sleepers 22 and metallically conductive rails 24.
- the Gleis ⁇ body 20 is made of plastic in the molding process, for example molding or injection molding.
- the thresholds 22 are also formed.
- the rails 24 are inserted into the mold and connected to the track body 20 or the rails 22 during casting.
- the track body 20 has a full cross section, its essentially flat upper side 26 and its sloping side surfaces support the ballast structure 18, its underside 30 is flat, as can be seen from FIGS. 2 and 3.
- the front end face lies in a connecting plane 32, in which both the flat end edge of the track body 20, including its sleepers 22, and the ends of the metallic rails 24 are located. These therefore do not protrude beyond the connection level 32, for example by means of contact tongues, nor do they stand back from it.
- This arrangement makes it possible for two model railroad tracks to butt against one another, the flush, flush design of the front being used to achieve a flush, butt-fitting fit of the rails.
- a recess 36 is provided, which is not recognizable from the outside in the case of two interconnected model railroad tracks, since the recess is only for each End face and the bottom 30 is open.
- the recess 36 is shown for receiving one half of a connecting element 38, as shown in FIGS. 1 and 2 below the recess 36.
- the connecting element 38 is fold-symmetrical to a center line 39 which lies in the connecting plane 32 in the case of assembled railway tracks. It is also fold-symmetrical about a longitudinal center line, which lies on the longitudinal central axis of the tracks in the case of assembled railway tracks.
- the connecting element 38 thus consists of two identically designed heads 40, each of which is provided for receiving in a recess 36, and a web 42 with a smaller cross section, which, as can be seen from FIG. 1, for example, is extremely short can, but also - as with - for example, Fig. 7 shows a certain length.
- the recess 36 has an undercut. Together with the head 40, which is wider than the web 42, this causes a positive connection of the connecting element 38 used. In other words, the inserted connecting element cannot be pulled out of the track body 20 in the direction of the arrow 44, but it can in the sense of the arrow 46 are pressed into the recess 36 from below.
- the recess 36 has a further undercut in the direction of the arrow 46.
- the recess 36 is dovetail-shaped, its side surfaces are inclined.
- the connecting elements 38 are preferably made of a plastic, but a different plastic is used for them than for the track body 20 with the sleepers 22.
- the plastic of the connecting elements 38 should be somewhat elastic, in particular it should practically not break.
- the plastic of the track body 20 and the sleepers 22 can be set relatively hard, here a very inexpensive plastic with a lot of filling material can also be used.
- the coordination with the material of the connecting elements 38 must be such that when the connecting elements 38 are used the material of the track body 20 can in no case be damaged, in particular the boundary surfaces of the recess 36 cannot be damaged, crumble or flake off.
- the configuration of the recess 36 shown in the figures is also designed so that no dangerous corners, edges or projections are formed which could break off when the connecting element 38 is pressed in. - Q -
- connection member 38 electrical connection will be described: As evident from the Fi ⁇ gures 1 and 2 it can be seen, the two rails 24 in each case via electrical connector 48 with Kunststoffzofien ⁇ 54 ver ⁇ connected, based on the top of the recess 36 are. On the upper side 52 of the connecting element 38 are these contact zone 'formed nc 54 associated Kunststoff50, the IRD assigned in pairs to each other' are electrically connected together. Upon insertion of the connecting element 38 in a recess 36 Aus ⁇ the contact zones with the contact surfaces 54 come into 50 e l ektrisch conductive contact, so that the electrical clock Kon ⁇ elements between the individual rails 24 via the seems ⁇ is prepared 38th
- the snap connection described which acts in the direction of arrow 46, is very advantageous for the electrical contact, because the contact zones 54 are pressed against the contact surfaces 50. " These zones can be designed in any way, for example as flat thin metal strips which are embedded in the respective plastic material, as strips or the like applied to discharge paint.
- the connection via the connectors 48 is also arbitrary, only one is decisive for the practice of safe electrical connection
- the contact surfaces 50 and the contact zones 54 are so large that contact between them is always achieved, regardless of manufacturing tolerances.
- the mechanical and electrical connection described in this way which is achieved via the recesses 36 and the connecting elements 38, is invisible in the assembled state.
- the mechanical connection is very secure and firm, since large forces can be transmitted over the relatively large areas.
- the electrical connection is also carried out very safely using simple means.
- the individual model railway tracks are simply placed on heads 40 of the connecting element 38 from above. presses, a lateral pushing together of the model railroad tracks is not necessary. In this respect, each individual model railway track can also be lifted in the direction of arrow 46 and removed from a closed association.
- a stiffening insert 58 is in the embodiment of Fig. 4, which is transverse to the bottom 30 and formed for example as a "metal profile. It will ensure that the fabricated track body material from Kunststoff ⁇ 20 not throw or bend can The insert 58 thus stiffens the track body 20, which is made of plastic, in its longitudinal direction in the sense of a reinforcement, thereby avoiding hollow parts of individual parts of the track body 20 on a base. 5 and 6, a connecting element 38 is shown, which enables a total of eleven separate connections between adjacent tracks. In addition to the two conductor tracks 60 required for pure driving operation, the additional conductor tracks can be used for any functions, for example switches, signals, train lighting or the like. A corresponding model railroad track is shown in FIG. 9.
- the underside of the connecting element 38 according to FIG. 5 can now be configured identically to the upper side 52 shown in FIG. 5. This has the advantage that the connecting elements 38 cannot be misaligned during assembly, so that it is avoided that, for example in the exemplary embodiment according to FIGS. 1 to 3, that surface of the connecting element 38 comes into contact with the contact surfaces 50 that even has no conductor tracks 60 and contact areas 50.
- the underside of the connecting element 38 does not carry any conductor tracks, so that attention must be paid to the orientation of the connecting element 38 when tracks are joined together. Instead, a number of sockets or contact openings 68 are provided on the underside, via which individual conductor tracks 60 can be electrically contacted. According to the invention, the current supply to the rails 24 does not take place on so-called connecting rails but via the connecting elements 38. Because of the sockets shown, it is possible to use each connecting element 38 as a connecting element. This simplifies the construction of a model railroad system because there is no need to differentiate between connecting parts and normal parts.
- FIGS. 7 and 8 Another embodiment of the connecting elements 38 is shown in the exemplary embodiment according to FIGS. 7 and 8.
- the purpose of this figure is in particular to explain that the connecting elements can basically have any shape, ie their heads are hexagonal, triangular, T-shaped or otherwise shaped. forms can be.
- the heads 40 shown in FIGS. 7 and 8 have an oval shape and are connected to one another by a significantly narrower web 42.
- This is elastic, for example made of a rubber material, and has an elasticity in the direction of the connecting line of the two heads 40. By this means that tracks connected to one another are pulled together in the direction of arrow 44, so that their end faces abut one another under pressure .
- the connecting element 38 also has push-button-like projections 62, which snap elastically into correspondingly shaped recesses in the track body 20. In this way, a frictional and positive connection of the track with the connecting element 38 is achieved and the elastic tension in the longitudinal direction, as described above, can occur.
- FIG. 9 shows a track which is referred to as an "intelligent rail" and which interacts with a connecting element 38, as is shown in FIGS. 5 and 6.
- the interconnects 60 are continued in the recessed rail floor.
- the conductor tracks 60 are partially completely covered, partially freely accessible below a recess area 64, this recess area 64 can be covered by a plate 66.
- contact sockets 68 are in turn arranged - Ü. -
- the additional conductor tracks 60 (which are required outside the traction power supply) are used for different functions. For example, it is possible to fasten a signal directly on the track body 20 and to wire it to the conductor tracks 60, possibly via contact sockets 68 of a plate 66. Numerous functions of a model railroad can be controlled without additional cables via the additional conductor tracks 60. Track detectors, sliding contacts and the like are also possible.
- FIGS. 10 to 12 Another exemplary embodiment is shown in FIGS. 10 to 12.
- the recess 36 in the end region of the rail shown (FIG. 10) is no longer fold-symmetrical to a longitudinal center plane of the track body 20.
- the connecting element 38 (FIG. 11) is also no longer fold-symmetrical to the corresponding longitudinal center plane , but it is rotationally symmetrical to the connecting plane 32.
- Recess 36 and, accordingly, both halves of the connecting element 38 are cuboid, an undercut is achieved by a pocket 70, which is also cuboid and has the same height as the recess 36, and thus enables a positive fit.
- a square projection 72 on the connecting element 38 fits into this pocket 70 with little play, this also has the same thickness as the rest of the connecting element 38.
- the track bodies 20 accordingly have differently designed connecting areas 34 at their two ends, the difference being that Orientation of the one pocket 70 at one end region, the pocket points to a side surface 28, at the other end region to the other side surface 28. This is reflected in the connecting element 38, as can be seen in FIG. 11.
- the rails 24 and the central conductor 56 are so high in profile (see FIGS.
- FIG. 11 has slots 74 machined on one of its main surfaces, which are arranged at a distance from the rails 24 or the central conductor 56, and has metallic contacts 76 on its inner walls, which when the connecting element is pressed in 38 come into a connection area 34 (see FIG. 12, arrow 46) in contact with the two rails 24 or the central conductor 56, insofar as these protrude freely downwards in the recess 36.
- the contacts 76 extend over the entire length of the slot 74 and thereby electrically connect the rails 24 and the central conductor 56 of two adjacent track bodies 20.
- the rails 24 or the central conductor 56 have perforations 78 which, for example, have a circular or oval shape and are visible in FIG. 10 are.
- the high-web rails 24 and the central conductor 56 also act in the sense of an insert 58, they have a high moment against bending transverse to the underside 30 of the Track body 20 and thus ensure that this underside 30 remains flat and can not throw. '
- semicircular projections 72 can also be used, as shown by the connecting element 38 according to FIG. 13.
- the bags must also be designed accordingly.
- the connecting elements 38 can be provided with through holes for screws.
- the lower surface of the connecting elements 38 can be provided with an adhesive film, but the underside can also be glued onto a carrier.
- the connecting elements 38 can thus be fastened on a carrier, for example a large plate, by different methods, then the track bodies 20 are pressed on from above, thereby achieving an invisible fastening, but a secure hold of the entire track system.
