Trailer hitch, especially for mail trolley, has tow bar overlapping and held against counter bearing in front of bolt in tow bar receiving part

摘要

The coupling bolt (12e) for passing through the eyelet (3a) in the tow bar (3) has a fixed and essentially vertical position. The tow bar-receiving part (12) has a counter-bearing (12f) located in front of the bolt with respect to the tow direction, which is used to restrict vertical movement of the tow bar. During use, the tow bar overlaps the counter-bearing with a degree of play and is held against it. The front end (5) of the trolley (1, 2) has a pivotally raisable tow bar, the free end of which has an eyelet.
