Plug-in element for the mechanical and electrically conductive connection of Rails, tracks and guideways in model making.

The object of the invention is, by means of the plug-in elements, the mechanical and - if desired - to enable the electrically conductive connection and disconnection of rails, tracks and guideways in model construction in such a way, that these can be used or lifted off at any time perpendicular to the laying plane.

The systems used so far see the tracks being put together by means of lugs located at the rail ends by sliding on the laying level, which is when laying and especially when repairs makes it necessary to loosen all neighboring tracks at the same time in order to obtain the required freedom of movement. This is often the case to damage, but always to deformation of the connecting straps.

The task mentioned at the beginning is made possible by the characteristics of the Characteristic part of the protection claim 1. solved. ■ / Further developments of the invention are disclosed in the subclaims.

The invention is explained in more detail with reference to drawings. It shows :

The plug element 1 ″ consists of a flat plate 1a, preferably made of Plastic, which on its underside on two opposite edges 1b, has strips or rows of teeth 1c running parallel to the edge and which is placed on the ends of the tracks to be connected 2 that this Strips or rows of teeth 1c with their closure surfaces 1d in to the Fixed surfaces 2d located at right angles to the longitudinal direction of the track - see secure while working on the two lengthways of the tracks

extending rows of teeth 1c of the flat plate 1a are shaped and dimensioned so that they rest resiliently on the foot 2b of the rails to be connected 2c and prevent the rails 2 from sliding against each other, with a perpendicular through the cement of the flat plate 1a guided around its longitudinal axis rotatable bolt 3 with z.3. Slotted head 3a with a T-shaped transverse spar 3b firmly attached to its lower end, which when inserting the plug-in element 1 initially slides through appropriately shaped recesses 2a on the track ends when inserting the plug-in element 1 and which, after the bars or rows of teeth 1c snap into the recesses 2a the track 2 by turning it by approx. 90 "pushes itself under the correspondingly shaped track ends, causes a releasable locking of the track 2 in the vertical direction.

With an appropriate design of the parallel to the track longitudinal axis running edges 4 on the flat plate 1a of the plug-in element 1, e.g. the attachment of a protruding, slightly resilient metal strip 4a, the electrical connection of the two adjacent rails 2c can also be effected, while a bolt 3 made of metal, for example also & can establish the electrical connection of a point contact strip 5 • if the ends 5 & this point contact strip 5 are shaped accordingly ^; are while the bolt head 3a also serves as a point contact.

λ The various embodiments with regard to the connection of Rail ends of various designs and the production of the electrically conductive connections are the following features within the scope of the present Invention common.

H The proposed plug element 1 is used for simple mechanical and electrically conductive connection of rails, tracks and guideways in model making, the ends of which are not pulled apart, as has been the case since then must be, namely, they are pushed into the connection position brought and connected to a plug-in element that can be placed on top, with a bolt on this plug-in element 1 on the top is attached, the head 3a · can be rotated by hand by approx. 90 ° after which the track connection is fixed.

The plug element 1 has according to the different on the Harkt slight differences between the forms located, e.g. that the rows of teeth 1c have different angles of inclination and different lengths to adapt to the shape of the track 2, or the length of the bolt

changes with the different track shapes.

Also have to borrow different from those on the market Different changes are made to the casting system, e.g.

in FIG. 2, formation 2a in contrast to the circular formation 2e in FIG. 4, or also the various bevels of the fixing surfaces 2d.

To the plug element according to the invention in existing track systems to be able to use only one or both ends of a piece of track need to be modified slightly, as in Figure 4 and Figure 2 can be seen. With the adapter system, only one end of the track is required to be changed.
