"Coupling for vehicles from üpielseu _o - and LodeH railways with a device for automatic decoupling" ^ _

The present invention relates to a clutch for Vehicles of toy and model railroads through which it is possible, e.g. 3. Traction vehicles not only safe with others Vehicles to couple automatically, but also without special Additional equipment on any 3 parts of the shade ice automatically uncouple from the other vehicles.

The coupling according to the invention is as follows due to the cleaning Features marked;

a) Each coupling half consists of a one-piece, preferably Hook-shaped profile part manufactured as a spray frame with an I-shaped attachment attachment when viewed from above, with this in a warehouse provided on the vehicle Spring force can be returned to the central position, both after both ueiten as well as pivoted in the vertical direction

In the figures, 1 represents part of the chassis of a drive train in which an approximately T-shaped recess 2 is provided. A recess A7, accessible from below, is covered by a plate 5 which can be attached to the chassis from below by means of a screw 4. The end of the chassis part 1 is provided with an opalt 5, wherein within the recess 2 egg head 6 of an I-shaped, from the head S and a neck 7 standing approach is located. The neck part 7 is continued by a transverse web 8, to which a web 9 running in the longitudinal direction of the vehicle is attached at right angles. At right angles to the part 9 is a triangular coupling nose 10 in cross section and at its end a relatively short extension 11 running backwards at right angles to the bevel. Jie i'eile 8 to 11 form a coupling hook which is mounted on the ΐ-shaped extension 6, 7 in the recess 2. In the narrower part of the recess 2, a helical spring 12 is provided, which opposes with its free end the head 6 of the * I-shaped Ans.at-ze.js, -6, - _k 7? supports. Lan takes from the drawings,

that due to a small lateral play between the gap, 5 and the neck 7 of the coupling hooks have a certain pivoting movement. can run to the left and right, being returned to its central position by the force of the spring 12. Of the .Spalt 5 also eats so that the coupling hook is also around a certain Jinkel can be pivoted upwards, whereby he. is also returned to its "horizontal starting position" again under the action of the spring 12 one further, · that if two with such a coupling hook equipped vehicles collide with each other, one of the two hooks moves upwards / so that the coupling position shown in Fig. 1 and 2 is obtained. It can also be seen from FIG. 2 that the rearward projections 11 result in a decoupling Evasion of the two coupling halves to the side is not possible.

The left opening half shown in the figures should be on a driving vehicle and the right coupling half can be provided on a driven vehicle. Accordingly, the means The direction of travel to the left is a pulling movement and the direction of travel to the right is a pushing movement. The coupling of the The driving vehicle is also approximately in the middle of the footbridge 9 provided with a pin 13, the end of which with a relatively large flat disk 14 is provided. On this pin 13, a rocker arm 15 is mounted, with a V-shaped Recess 16, 17, above the shorter leg 16 of the recess runs approximately transversely to the longitudinal extent of the drag lift and is at its end somewhat widened towards the bottom. The longer leg 17 of the recess extends in the direction of the longitudinal rocker arm. The lower end of the rocker arm is held by a edge 18 extending transversely to its longitudinal direction, wherein '

the width of this 3 rocker arm at the bottom. Somewhat bigger at the end is chosen as the distance between two sleepers 19 of the track 20. At the transition point between the lower boundary 18 and the lateral boundaries of the rocker arm bevels 21 and 22 are provided. As material for the A viscoplastic plastic is preferably proposed.

The length of the recess 16 must be chosen to be at least as large Y / earth that the pin 13 is held securely in this when the ^ The driving vehicle moves backwards a short distance from a pulling movement, the coupling hook being the one shown in Fig.3a position shown. The length of the tow is straight dimensioned so large that, as Fig.3a shows, the coupling hook up to is raised over the uncoupling division. Is that moving Vehicle closer to the right, the positions of the coupling hook and rocker arm shown in Fig. 3b and 3c are taken, the left coupling hook again assumes its horizontal coupling position shown steepness again to the left, then comes the Chew 18 of the rocker arm 15 in the stop on one of the thresholds 19, whereby the pin 15 ia the second Se & ankel 17 of the V-shaped Recess arrives. Here, the rocker arm 15 moves again; in dit back position shown in dashed lines in Fig.3a without the coupling hook is lifted in the process.

The coupling proposed according to the invention thus allows .by a simple change of direction from a pulling movement to a pushing movement of the driving vehicle to decouple it from the driven vehicles. üJird the pushing movement , continued, the clutch is re-engaged and at

Animals from the pushing to the pulling movement only engage the clutch. The particular advantage of the coupling according to the invention is that the coupling is not released when pushing on a downhill stretch and the train cannot break.
