AI Technical Summary

Technical Problem

Existing model railway couplers lack efficient automatic uncoupling mechanisms that do not require electrical components on both wagons, and existing couplers are not designed to accommodate varying curve radii effectively.

Method used

An electric model railway coupler with a motor-operated rocker arm and a slider with a fork and cam mechanism, along with a jointed coupling head and steel springs, allows for automatic uncoupling without electrical components on one wagon and accommodates different curve radii.

Benefits of technology

Enables automatic uncoupling of wagons with compatible couplers without additional electrical components and ensures smooth operation through varying curve radii.

Abstract

Electric model railway coupling, characterized in that it is equipped with a rocker arm (Fig.1 No.6) and lifts both its own closing rod with closing bracket (Fig.1, No.3 and No.4) and the closing rod with closing bracket (Fig.2, No.3.1 and No.4.1) of the opposite coupling.

Description

[0001] Electric model railways of gauge 1 and (gauge G), suitable for the coupling for model railways of gauge 1 and (gauge G) with utility model no. 20 2024 002 219 (mentioned only as an example).

[0002] The electric model railway coupler is used for the automatic uncoupling of wagons with a compatible coupler. The coupler of the opposite wagon, which is coupled to this coupler, does not need to have its own electrical components.

[0003] The electric model railway coupling has a motor that operates a rocker arm via a slider with a fork (with a cam).

[0004] This rocker arm lifts its own and the closing rod of the opposite coupling, thus releasing the couplings from each other.

[0005] In order to be able to follow curve radii, the coupling head is designed as a joint over the vertical axis and is centered with 2 steel springs. (The drawings do not show the feathers, only the photographs)

[0006] An example implementation will be shown using the Fig. 1, Fig. 1a and Fig. 2 shown: Fig. 1.
