Definitions

  • the invention relates to a model railway track for electric model trains according to the preamble of claim 1.
  • the connecting elements in cross-section have rectangular, slotted tube sections which are inserted from the connecting plane in the longitudinal direction of the track into recesses formed laterally next to the rails and below these as slots will.
  • a piece of pipe which is made of metal, is provided for each rail. It overlaps the rail foot in the area of its slot and thereby establishes electrical contact with the rail.
  • connecting pins which preferably have the shape of a U-shaped bracket, are provided in order to block separation of the tracks in the longitudinal direction.
  • a model railroad track is known from GB-A-20 35 105, in which the rails are electrically connected by tongues which are pushed together in the longitudinal direction.
  • the mechanical connection of the railway track in ladder structure is achieved using connecting elements.
  • the object of the invention is to provide a model railroad track that allows a more realistic replica and provides as a prerequisite for this connection areas that enable the connection of adjacent tracks without moving in the longitudinal direction and allow a more convenient establishment of the connection.
  • a particular advantage of the connections obtained is that each individual model railway track can be individually lifted up out of a series of interconnected tracks, because no lateral clearance is required, for example, no contact tongues protruding from the connection level are necessary to push the model railway tracks together their longitudinal direction.
  • the connecting elements enable a very large and thus effective mechanical cohesion of neighboring model railroad tracks.
  • the production of the recesses is relatively simple, preferably the recesses also have the simplest possible geometrical shape, for example pitch circle shape, hexagon shape, push button shape or the like.
  • connection areas ensures an always clean, gap-free adjoining of two neighboring ones Model railroad tracks reached.
  • the connection areas are practically no longer recognizable with a suitable design of the model railroad tracks, contact tongues are not necessary, so that the rails also run through the area in the area of the connection areas according to the great model, in any case have no thickening points, as caused by contact tongues.
  • the connecting element has contact surfaces which are electrically connected to one another and are located on its top side or on its side surfaces. On the underside or the side surfaces of the recesses of the model railroad tracks, contact zones associated with these contact surfaces are provided, at least two of which are electrically connected to the rails.
  • the connecting elements thus not only effect a mechanical but also an electrical connection of adjacent rails. It is very favorable that the electrical connection is not only possible for two electrical contacts, but that a significantly larger number of connections can be provided.
  • 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 problems.
  • the connecting elements are preferably also fold-symmetrical to a plane of symmetry running through the longitudinal center of adjacent model railroad tracks. This improves their universal use, and the assembly of model railroad tracks with them is simplified. If, in addition, the bottom and top of the connecting elements are of identical design and each provided with contact surfaces, a special arrangement or alignment of the connecting elements is no longer necessary because they always fit.
  • the two head regions of a connecting element are generally connected to one another by a central web which is elastic. It is narrower than the head areas, which creates a positive fit. Due to the elastic design of the web it is achieved that the two connection areas of adjacent model railway tracks are elastically pulled against each other in the connection state, whereby a gap in the connection area is reliably avoided and a very good mechanical hold is achieved. The measure also improves the electrical connection.
  • a second positive connection is possible, which acts transversely to the plane of the two rails.
  • a push-button connection is provided, which is provided between each half of the connecting element and part of the recess of the model railroad tracks.
  • the track body and sleepers are preferably made of plastic, which is preferably set hard, in the full cross section and an insert stiffening this body is embedded in the track body.
  • the plastic construction enables on the one hand very simple insulation of the electrical lines, but in particular the rails. Additional insulating agents, such as are necessary for metal track bodies, are not required. This greatly simplifies production.
  • the plastic track bodies have the advantage, however, that the track edges do not have to run in a straight line, that any course can be reproduced, as they also occur with a large prototype. This gives the track body a much more natural shape and a significantly improved appearance.
  • the track bodies are preferably made from a plastic material using the casting process, the rails being cast in at the same time.
  • connecting elements with electrical connections for the voltage supply to the tracks and possibly other parts.
  • the electrical voltage supply is no longer carried out on the tracks, but on the connecting elements, which simplifies the manufacture of the tracks and in particular it it is no longer necessary to specifically use so-called connecting tracks and normal, i.e. no electrical connection tracks when building a railway system.
  • the electrical connections can be easily formed on the connecting elements, for example plug contacts can be provided on each connecting element, into which — if a connecting element is to be used as a connecting piece — connecting wires can be plugged in.
  • a model railroad track for electrical model railways 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 track 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 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, blunt fit of the rails being achieved by the carefully flat design of the end face.
  • a recess 36 is provided in each of the two end-side connection areas 34 (only one is shown in each of FIGS. 1 to 3), which is not recognizable from the outside in the case of two model railroad tracks connected to one another, since the recess only points towards the end face and the underside 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 about a center line 39 which lies in the connecting plane 32 in the case of assembled railway tracks. It is also fold-symmetrical to 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, which are each provided for receiving in a recess 36, and a web 42 with a smaller cross section, which, as can be seen for example from FIG. 1, can be extremely short, but also - like for example Fig. 7 shows can have a certain length.
  • the recess 36 has an undercut. Together with the head 40, which is wider than the web 42, this brings about a positive fit of the connecting element 38 used. In other words, the connecting element used cannot be pulled out of the track body 20 in the direction of the arrow 44, but it can be moved from the bottom in the direction of the arrow 46 Recess 36 are pressed.
  • the recess 36 has yet another 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 using the connecting elements 38 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 design of the recess 36 shown in the figures is also designed such that no dangerous corners, edges or projections are formed which could break off when the connecting element 38 is pressed in.
  • the two rails 24 are each connected via electrical connectors 48 to contacts 54 which are located on the upper side of the recess 36.
  • contacts 54 which are located on the upper side of the recess 36.
  • contact areas 50 assigned to these contact zones 54 are formed, which are assigned to one another in pairs and are electrically connected to one another.
  • the snap connection described which acts in the direction of the 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 manner, for example as flat thin metal strips which are embedded in the respective plastic material, as strips or the like applied with a conductive paint.
  • the connection via the connector 48 is also arbitrary, the only decisive factor is a practical 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 railroad tracks are simply pressed onto heads 40 of the connecting elements 38 from above, there is no need to push the model railroad tracks sideways. In this respect, each individual model railroad track can also be lifted in the direction of arrow 46 and removed from a closed association.
  • FIGS. 1 to 3 a model railroad track with a central conductor 56 is shown, otherwise the design is largely the same as the embodiment according to FIGS. 1 to 3.
  • a stiffening insert 58 is shown in the exemplary embodiment according to FIG. 4, which runs transversely to the underside 30 and is designed, for example, as a metal profile. It ensures that the plastic track body 20 can not throw or bend.
  • the insert 58 thus reinforces the track body 20, which is made of plastic, in its longitudinal direction in the sense of a reinforcement. Hollow lying of individual parts of the track body 20 on a base is thereby avoided.
  • a connecting element 38 is shown, which enables a total of eleven separate connections between adjacent tracks.
  • 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 identical to the upper side 52 shown in FIG. 5. This has the advantage that the connecting elements 38 cannot be misoriented 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 which does not have any conductor tracks 60 and contact surfaces 50 has.
  • 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 rather 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, that is, their heads are hexagonal, triangular, T-shaped or otherwise could 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. This ensures that interconnected tracks are pulled together in the direction of arrow 44, so that their end faces abut each other 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 to 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 arranged, via which the individual conductor tracks 60 are electrically accessible (alternatively or in addition to the embodiment according to FIG. 6).
  • the additional conductor tracks 60 (which are necessary outside the traction power supply) are used for different functions. For example, it is possible to attach a signal directly to 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 railway can be controlled via the additional conductor tracks 60 without additional cables. 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 shown end region of the rail (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 Connection level 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.
  • this pocket 70 fits a cuboid projection 72 on the connecting element 38 with little play, this also has the same thickness as the rest of the connecting element 38.
  • the track body 20 accordingly have differently formed connecting areas 34 at both ends, the difference lies in the orientation of the one Pocket 70, at one end region the pocket points to one 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 from FIG. 11.
  • the rails 24 and the central conductor 56 are so high in profile (see FIGS. 10 and 12) that they extend practically through the entire track body 20, but their lower edge is still somewhat above the underside 30 of the track body 20 remains, so that they only project freely downwards and thus in a contactable manner in the area of the two end recesses 36, whereas they otherwise only project above the track body 20, that is to say are embedded and insulated downward.
  • the relatively high-level design of the rails 24 and the central conductor 56 makes it possible to dispense with electrical connectors 48 or specially designed contact zones 54; rather, the rails 24 and the central conductor 56 can be contacted directly on them themselves.
  • the connecting element 38 according to FIG.
  • 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 their inner walls, which when the connecting element 38 is pressed into a connecting area 34 (see FIG. 12, arrow 46) come into contact with the two rails 24 or the central conductor 56, insofar as these protrude freely downward 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.
  • 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.
  • FIG. 12 shows how track body 20 and connecting element 38 are pressed against one another during assembly, this is symbolized by arrow 46.
  • arrow 46 When pressed in, on the one hand the areas of the rails 24 or the central conductor 56 which project freely below come into contact with the contacts 80, and on the other hand the projection 72 engages in the pocket 70.
  • Fig. 12 shows the state shortly before completion of the assembly.
  • semicircular protrusions 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 to a carrier.
  • the connecting elements 38 can thus be fastened to 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.
