Abstract: An adapter coupler (1) for adapting couplings of different design, wherein the adapter coupler (1) comprises a first connecting mechanism for releasably connecting the adapter coupler (1) to a first coupling, a second connecting mechanism for releasably connecting the adapter coupler (1) to the drawhook (50) of a second coupling, and a coupler housing (2) for connecting the first connecting mechanism to the second connecting mechanism, and wherein the second connecting mechanism comprises a tension yoke (8) with which to engage with the drawhook (50) of the second coupling.

Abstract: A coupling head housing of a central buffer coupling for rail vehicles, especially low-platform vehicles, with a lock with rotatable disk-type hook and articulated coupling ring, which is located retracted inside the centering projection when the coupling is not in use, and with a funnel for receiving the centering projection of an opposite coupling head of the same design. Offsets in height and lateral offsets, but even angular offsets are to be compensated prior to the coupling process. Accordingly, the front part, which combines a compact design with the known advantages of older coupling designs for the largest possible gripping range, within which a coupling process can still be initiated as intended when the coupling head housings are axially offset in relation to one another and it can be concluded after the adjustment to one another.
