Claims (2)

1 2 anchored. However, due to the patent claims: straight edges of the sheet metal flap, this anchoring is not very reliable; this results from the fact that in this version the central conductor plate has a special 1. Arrangement for attaching the point 5 clamp-like brackets on the rails and the Contact track of a center conductor forming ladder longitudinal webs of the sleeper body are attached shaped sheet metal on the underside of a ladder-must. shaped sleeper body made of plastic for the object of the invention is the known Toy railway track pieces with central conductor, to avoid fastening types own disadvantages, characterized in that in itself io ie a reliable in use and nevertheless known way to create the fastening which forms the point contacts is easy to manufacture.
Sheet metal tabs (2 c) from the center conductor plate (2) To solve this problem, a combination are bent upwards around a bending edge perpendicular to the track axis from known and a new feature and hit each sheet metal tab. This solution consists in that in per se (2c) a transverse sleeper (la) penetrates in a manner known to the cross-section of the sheet metal tabs forming the section of the sheet metal tabs that is adapted to form the rectangular sheet metal tabs from the central conductor plate around a hole (F), and that the upper end of the track axis vertical bending edge upwards gedes the point contact forming sheet metal tabs with curved, each sheet metal tab is provided with a cross over the hole (F) in the sleeper (la) reaching threshold in a cross-section of the sheet metal tab barbs (2 d) . 20 adapted, rectangular hole penetrates, and that 2. Arrangement for attaching a central, the upper end of the point contact forming conductor according to claim 1, characterized in that sheet metal tabs with over, the hole in the threshold that the width of the central conductor plate (2) is provided equally gripping barbs. This Widerdem distance between the outer ends of the two hooks prevent the rail feet (3 b) of the rails from slipping back and that a moderate force occurs on the underside of the sleeper body. This training has flat recess of the same width is provided, furthermore the advantage that due to the track axis in which the center conductor plate (2) is flush and flush with the vertical bending edges of the sheet metal tabs below the base (S) fits into it. . the rails of the central ladder 30 sheet must be pressed securely upwards against the longitudinal spars of the sleeper body. That on Bending stressed cross bars of the central ladder sheet metal, as they are as wide as the sleepers can be maintained, the relatively favorable bending resistance moment. Also enables it is the intended, known arrangement for making contact with the wiper The invention relates to an arrangement for holding the point contact track of a central upper edge of the sheet metal tabs on the 40, whereby the wear is low and the underside of a ladder-shaped sleeper body can be reliably kept from making contact .
Plastic for toy train tracks with an expedient development of the invention Center conductor. - is that the width of the central conductor plate In a known design (German patent - equal to the distance between the outer ends of the two writing 1 169 824) is the fastening of the ladder rail feet of the rails, and that on the shaped central conductor plate on the sleeper body there- underside of the sleeper body a flat opening achieved that the point contacts forming the same width assumption is provided in which the Sheet metal tabs from the center conductor plate around one to the center conductor plate and flush with the base Track axis vertical bending edge bent upwards fits into it in alignment. ' Each sheet metal tab is a! cross sleeper in a 50 As a result, the punched cut for the hole is penetrated on the one hand and then the cross sleeper is bent horizontally around the central conductor plate on the outer long sides. This Umlinig, ie very simple; On the other hand, central bending requires a special conductor plate in the shallow recess during manufacture. ; '■ - .. · .. Facilitating assembly and preventing lateral In another known type of fastening 55 slides secured space. In addition, through the central conductor plate (French patent specification of the aligned formation of the underside of track 1 255 104), the pieces forming the point contact tips achieve an optimal footprint.
Sheet metal tabs around a parallel to the track axis. The drawing shows an embodiment. The bending edge is bent upwards. Feder, in the present F i g. 1 shows the cross-section of a piece of track the case of relatively narrow sheet metal flaps is 60 (according to line CC in FIG. 3), while
during assembly in a preformed, downwardly FIG. 2 shows the top view of a part of the central open, round blind hole of the associated transverse conductor plate; . threshold pushed in until the upper end Fig. 3 shows the top view of part of the of the sheet metal flap the upper, liaut-thin end of the track section according to FIG. 1 in direction A ;
of the blind hole breaks through. On the basis of the Ve, r- 65 Fig. 4 shows part of the sleeper body in the form of the plastic is then the sheet metal tab, the view from below (direction ^ *).
