Description

Automatically disengageable coupling for toy train vehicles The invention relates to a coupling for toy railway vehicles, in which the wagons are automatically coupled by driving against each other, after operation the uncoupling device: but can be separated again by moving them apart can.

The device according to the invention consists in that: on the one hand each of the two equalize the couplings attached to the two ends of the car a dome bracket that can be swiveled upwards and a dome finger pointing upwards exists, which is engaged behind by the bracket of the next car when the car is coupled and on the other hand from a means lying in the track, with which the coupling bracket through Raising, triggered when the coupling is to be disengaged. This agent can be operated by hand lifted up «'earth and then hits a base of the dome bracket, on, on this way, in turn, is lifted up and thereby triggered. When railway vehicles were received with automatic clutches these are not present in an advantageous manner Invention, d. H. not longitudinally and transversely symmetrical, formed, but: as one-sided mounted coupling hooks, so that a one-sided effect when coupling and uncoupling takes place, which consists of thin sheet metal parts of the coupling and their axes not withstand in the long run, or breakdowns can easily occur.

The longitudinally symmetrical design and arrangement of the coupling parts, d. H. a coupling bracket according to the invention, also enables such an action of the decoupling means that its stress when decoupling is also symmetrical distributed to the longitudinal axis and attacked evenly on the coupling hill. It happens this in that the uncoupling is carried out by an attack from the bottom up is by placing a lying in the longitudinal direction of the track Switch bracket is lifted, which then hits an approach of the coupling bracket and this thereby raises.

But then the hitching and uncoupling device has to follow the Invention above all the advantage that the car is not as in the known facilities can only be decoupled while driving, but also while standing. That virtue is attributed to it, i.e. the lifting of the coupling bracket by the movement of is made down to the top while the uncoupling movement at known Devices in the direction of travel takes place, insofar as this is done in the track after above finger pivotable about a horizontal transverse axis is used.

In itself, however, it has already become unknown, the uncoupling by moving the decoupling means from bottom to top, but it then the whole car became hocligeli, obcti that is impractical.

The switch bracket expediently has a U-shaped cross section, wherein its two legs on either side of the track center rail - so that they Approach the correspondingly wide decoupling attachment of the coupling bracket symmetrically.

To lift the switch lever, it is at the end of a lever. the mechanically, z. B. by means of a finger button, or also electrically, for. B. can be controlled by means of an electromagnet.

To prevent the car from coupling or reversing come so close to each other that the clutches could malfunction, each coupling is provided with a stop directed towards the next wagon, which consists of a wide, downward curve of the carrier of the coupling. -These stops then advantageously also form the support for the dome bracket and the starting point for the dome fingers pointing upwards.

The object of the invention is on the drawing, for example shown.

Fig. Z shows a side view of two cars to be coupled at the uncoupling point. Figures 2, 3 and 4 show these cars being coupled, coupled and uncoupled. Figure 5 is a bottom view of two cars on a curve.

Figures 6 and 7 are end and plan views of a car and its, respectively Coupling. Fig. Ä is a side view of the uncoupling device, cut vertically.

The Wageaa to be coupled to a toy train, which on the Rails b of the track running are at both ends - with an automatic coupling provided, "- who couple the carriages by simply driving against each other.

This coupling device is designed and arranged in such a way that it does not matter whether the wagons @a are coupled with one or the other facing each other on the other side. For this purpose the couplings, as especially Figs. 6 and 7 show, partly in the central axis of the car rc arranged, and on the other hand its individual parts are symmetrical to this central axis formed and arranged.

The couplings each consist of a coupling bracket c, which is around a Transverse axis d is pivotably mounted to .oben on the carriage a. Furthermore, they always exist from an upturned finger, which in the coupled position (Fig. 3) is behind the bracket c of the neighboring car a, d. according to it finds a mutual Reaching behind the fingers on both sides of two Wageaa to be coupled instead. To a to enable automatic coupling when two carriages a are driving against each other the contact surfaces at the front coupling bracket c and coupling finger e are set at an angle accordingly, d. H. the front end f of the bracket c is slightly bent upwards, while the fingers ; e are placed slightly backwards at an angle. When the sloping end f of a bracket c runs onto the inclined finger e of the neighboring car a, which is in the same direction, it is thus automatically pushed up (Fig. 2) and finally falls over the finger e (Fig. q), whereby the coupling of the two carriages a is established.

In order to prevent the car to be coupled, a too far against each other can be driven, be it when coupling or when reversing, is A stop ä is provided on each coupling, which, as shown in Fig. is curved, so that the two stops u rest against each other when reversing and can roll over one another in a curve, for example.

The stops & are located at the front end of the carrier h the Coupling and form a downward turn of the same. On the carrier h is also the pivot: axis, d of the coupling bracket c. The front end of the Carrier h also simultaneously forms a support for the coupling bracket c, so that this cannot lower itself under the detachable position. Goes on from the front The end of the beam is also shown by the dome finger pointing upwards.

The carrier k and thus the whole coupling is perpendicular to one another Bolt i on the underside of the car a laterally weldable, and around the Couplings despite-Z> to hold it automatically in its middle position, are the rear ends of the beams k of the couplings mounted on the same carriage a connected to one another by a tension spring h.

As with toy trains, especially with the small version of the Car, a for uncoupling, d. H. for lifting the cup; elbow c, for the finger If there is not enough space, the uncoupling is done ziveckweise by means of a mechanical one. Made by hand, in a specific place of the track b. For this purpose there is a means, usually sunk, in track b L provided, which can be lifted somehow by hand and then in turn lifts the two coupling brackets c of the coupled car. For this purpose are located on this downwardly directed flap zn, on which the decoupling means l hits when being lifted and thereby triggers the coupling bracket c.

A switch bracket is expediently used as the uncoupling means L, which is in the middle of track b and is U-shaped, with his both legs are on both sides of the central rail and on both longitudinal ends , fall off so as not to impede driving. This switch bracket L is located at the end of a lever az, which is pivotable about a transverse axis, o. This uncoupling lever can be controlled mechanically by hand, namely by means of a finger button p or electrically by means of a vain electromagnet g. Control of the lever n is done by means of a second lever r which extends over its free end, the is pivotable about a cross bolt s. The finger button is also located on this lever r p, and with electrical control of the coupling device, the lever serves as Anchor. After releasing the finger button p-, or after switching off the electrical one Stromes the switch bracket l automatically goes back down, so z. B. be through Own weight.
